Description
~.o6~4 The invention relates to an electrostatic or xerographic copying and duplicating apparatus, in which the originals to be copied or duplicated are placed, for illumin-ation, face down on a transparent ~upporting surface, e.g.
a sheet of glass, two covers or templets forming a ~lot being arranged on the said transparent supporting surface, if necessary in plastic envelopes, an additional templet, if necessary in a plastic cover, being arranged line-wise dis-placeably above the said first templet~, and the lines in this additional templet being exposed, for illumination, in the slot in the two covers or templets lying thereunder.
In apparatuses of this kind, as a rule only partial use is made of the sheets of copying paper of conventional size used, since usually only portions of the originals placed in the apparatus are duplicated. However, sheets of copying paper of different sizes cannot be fed into an apparatus of this kind, since the said apparatus is normally designed for one size only and conversion for sheets of different sizes would require considerable structural alterations. Thus the copies made by the apparatus either have blank areas of different sizes or, in order to make better use of the sheets of a given size, several items are copied onto a single sheet.
In either case, the sheets of copying paper must be cut up manually, either to remove the unused portions of each sheet, or to separate the various items on a single sheet.
It ls the purpose of this present invention to dis-pense with this subsequent manual cutting up of the sheets of copying paper, which involves a considerable amount o~ labour.
According to the invention, this purpose is achieved, in the case of the copying and duplicating apparatus mentioned at the beginning hereof, in that a plurality of devices for cutting up the sheets of copying paper is arranged in the path of the said paper between the fixing device and the area where the copies are stacked, the said cutting devices acting in the direction of feed of the said sheet~ of copying paper. ~t i8 desirable that the said cutting devices be in the form of two counter-rotating cutter blades, the individual devices being preferably adapted to be brought into their operative po~itions selectively for specific sizes of sheet.
The invention is explained hereinafter in greater detail in conjunction with the drawings,wherein:
Fig. 1 is a simplified representation of a xerographic copying apparatus with a cutting device, and Fig. 2 show~ the cutting device in Fig. 1 to an en-larged scale.
~ he xerographic copying apparatus illustrated in Fig. 1 has a drum 2 provided with a layer of selenium 1, the 3aid drum being rotated about a shaft 3 by mean~ of a drive, not shown. Arranged at the outer peripbery of drum 2, and extending over the entire length thereof, i8 a charging device 4 by means of which an electrical charge is imparted to the area of selenium layer 1 passing by. By means of a pivotable mirror 5, a lens 6, a stationary mirror 7, and an additional lens 8, a mirrox image of the originals located on a trans-parent supporting surface 9 is projected onto selenium layer 1.
The said original~ are illuminated by means of lamps 10 and reflectors 11 arranged behind the said lamps.
The movement of pivotable mirror 5 is synchronized with that of drum 2, so that the uncovered areas of the originals are projected onto selenium layer 1. The electrical charges 10614~
previously applied to the said selenium layer by charg$ng device 4 are era~ed at the illuminated locations, remaining only at the image locations. As drum 2 moves onwards, the charged image locations in the selenium layer are brought within range of a dusting device 12 where the said selenium layer is brought into contact with a powder which adhere~
only to the charged image locations. A sheet 15, fed by feed rollers 13,14, is moved pa~t drum 2 for a suitable period of time, the powder image being transferred from selenium layer 1 to sheet 15 by means of a transfer device 16. Sheet 15 then passes, with the readable powder image, to a fixing station where the said powder image is fused solid by an infra-red radiator 17. Before selenium layer 1 is charged again, any powder remaining thereon is removed in a cleaning station 18.
After passing through the fixing station, sheet 15 is passed by feed rollers 19,20 to a plurality of cutting devices arranged one behind the other, at right angles to the direction of travel of sheet 15, and over the entire width thereof. The number of cutting devices depends upon the number of piece~ into which it is desired to cut sheet 15. As a result of the aforesaid arrangement of the cutting devices in relation to each other, only one such cutting device ~s visible in Figs. 1 and 2, but the others are of id~ntical design. Each cutting device comprises two rotating blades 21,22 arranged one above the other, both of them being driven by a motor, not shown, through belts 23,24, in the ~ame direc-tion as feed rollers 19,20. Upper blade 21 is held in a frame 25 adapted to pivot ~etween two stops 26,27 about an axis 28.
When an electro-magnet 29 connected to frame 25 is energized, the said frame lies against stop 26, as shown in Figs. 1 and 2.
In this position, blade~ 21,22 are arranged in relation to each other in a ~anner such ~hat a sheet 15 pa~sing through the cutting device is parted in the direction in which it is travelling. If electro-ma~net 29 i8 not energized, a spring 30 causes frame 26 to lie against stop 27. ~n this position, blades 21,22 are far enough ap~rt to allow a sheet to pa~s between them uncut. Thus when individual electro-magnets 29 are energized selectively, sheet 15, before it reaches ~tacking tray 31, may be cut, in its direction of travel, one or more times, at selected locations. If none of the electro-magnets is energized, the sheet passes to the $ray uncut. Electro-magnets 29 are preferably controlled by keys actuated by the operator. It is desirably that one key be assigned to each electro-magnet.
The originals are arranged face down on supporting surface 9, in transparent folders 32,33, the said folders being secured by clamping means 34,35 arranged at the e~dge of the said supporting surface and extendlng over the entire length thered~-; or the said originals may be held directly by the said clamping means. Arranged in lower folder 33 are two templets forming a slot in the scanning direction of pivotable mirror 5, or one templet and one cover. A portion of the original in upper cover 32 is visible from below through the said slot. Clamping means 34 is displaceable longitudinally, i.e. at right angles to the plane of the drawing. Thus the upper original can also be moved, so that the portion thereof projected through the slot onto ~elenium layer 1 may also be changed. A transparent strip of foil 38, carried on spools 36,37, is arranged to move between the two spools. This strip carries various blanks or masks, one of which may be placed between supporting surface 9 and lower folder 33, so that visible parts of the originals can be projected onto selenium layer 1.
a sheet of glass, two covers or templets forming a ~lot being arranged on the said transparent supporting surface, if necessary in plastic envelopes, an additional templet, if necessary in a plastic cover, being arranged line-wise dis-placeably above the said first templet~, and the lines in this additional templet being exposed, for illumination, in the slot in the two covers or templets lying thereunder.
In apparatuses of this kind, as a rule only partial use is made of the sheets of copying paper of conventional size used, since usually only portions of the originals placed in the apparatus are duplicated. However, sheets of copying paper of different sizes cannot be fed into an apparatus of this kind, since the said apparatus is normally designed for one size only and conversion for sheets of different sizes would require considerable structural alterations. Thus the copies made by the apparatus either have blank areas of different sizes or, in order to make better use of the sheets of a given size, several items are copied onto a single sheet.
In either case, the sheets of copying paper must be cut up manually, either to remove the unused portions of each sheet, or to separate the various items on a single sheet.
It ls the purpose of this present invention to dis-pense with this subsequent manual cutting up of the sheets of copying paper, which involves a considerable amount o~ labour.
According to the invention, this purpose is achieved, in the case of the copying and duplicating apparatus mentioned at the beginning hereof, in that a plurality of devices for cutting up the sheets of copying paper is arranged in the path of the said paper between the fixing device and the area where the copies are stacked, the said cutting devices acting in the direction of feed of the said sheet~ of copying paper. ~t i8 desirable that the said cutting devices be in the form of two counter-rotating cutter blades, the individual devices being preferably adapted to be brought into their operative po~itions selectively for specific sizes of sheet.
The invention is explained hereinafter in greater detail in conjunction with the drawings,wherein:
Fig. 1 is a simplified representation of a xerographic copying apparatus with a cutting device, and Fig. 2 show~ the cutting device in Fig. 1 to an en-larged scale.
~ he xerographic copying apparatus illustrated in Fig. 1 has a drum 2 provided with a layer of selenium 1, the 3aid drum being rotated about a shaft 3 by mean~ of a drive, not shown. Arranged at the outer peripbery of drum 2, and extending over the entire length thereof, i8 a charging device 4 by means of which an electrical charge is imparted to the area of selenium layer 1 passing by. By means of a pivotable mirror 5, a lens 6, a stationary mirror 7, and an additional lens 8, a mirrox image of the originals located on a trans-parent supporting surface 9 is projected onto selenium layer 1.
The said original~ are illuminated by means of lamps 10 and reflectors 11 arranged behind the said lamps.
The movement of pivotable mirror 5 is synchronized with that of drum 2, so that the uncovered areas of the originals are projected onto selenium layer 1. The electrical charges 10614~
previously applied to the said selenium layer by charg$ng device 4 are era~ed at the illuminated locations, remaining only at the image locations. As drum 2 moves onwards, the charged image locations in the selenium layer are brought within range of a dusting device 12 where the said selenium layer is brought into contact with a powder which adhere~
only to the charged image locations. A sheet 15, fed by feed rollers 13,14, is moved pa~t drum 2 for a suitable period of time, the powder image being transferred from selenium layer 1 to sheet 15 by means of a transfer device 16. Sheet 15 then passes, with the readable powder image, to a fixing station where the said powder image is fused solid by an infra-red radiator 17. Before selenium layer 1 is charged again, any powder remaining thereon is removed in a cleaning station 18.
After passing through the fixing station, sheet 15 is passed by feed rollers 19,20 to a plurality of cutting devices arranged one behind the other, at right angles to the direction of travel of sheet 15, and over the entire width thereof. The number of cutting devices depends upon the number of piece~ into which it is desired to cut sheet 15. As a result of the aforesaid arrangement of the cutting devices in relation to each other, only one such cutting device ~s visible in Figs. 1 and 2, but the others are of id~ntical design. Each cutting device comprises two rotating blades 21,22 arranged one above the other, both of them being driven by a motor, not shown, through belts 23,24, in the ~ame direc-tion as feed rollers 19,20. Upper blade 21 is held in a frame 25 adapted to pivot ~etween two stops 26,27 about an axis 28.
When an electro-magnet 29 connected to frame 25 is energized, the said frame lies against stop 26, as shown in Figs. 1 and 2.
In this position, blade~ 21,22 are arranged in relation to each other in a ~anner such ~hat a sheet 15 pa~sing through the cutting device is parted in the direction in which it is travelling. If electro-ma~net 29 i8 not energized, a spring 30 causes frame 26 to lie against stop 27. ~n this position, blades 21,22 are far enough ap~rt to allow a sheet to pa~s between them uncut. Thus when individual electro-magnets 29 are energized selectively, sheet 15, before it reaches ~tacking tray 31, may be cut, in its direction of travel, one or more times, at selected locations. If none of the electro-magnets is energized, the sheet passes to the $ray uncut. Electro-magnets 29 are preferably controlled by keys actuated by the operator. It is desirably that one key be assigned to each electro-magnet.
The originals are arranged face down on supporting surface 9, in transparent folders 32,33, the said folders being secured by clamping means 34,35 arranged at the e~dge of the said supporting surface and extendlng over the entire length thered~-; or the said originals may be held directly by the said clamping means. Arranged in lower folder 33 are two templets forming a slot in the scanning direction of pivotable mirror 5, or one templet and one cover. A portion of the original in upper cover 32 is visible from below through the said slot. Clamping means 34 is displaceable longitudinally, i.e. at right angles to the plane of the drawing. Thus the upper original can also be moved, so that the portion thereof projected through the slot onto ~elenium layer 1 may also be changed. A transparent strip of foil 38, carried on spools 36,37, is arranged to move between the two spools. This strip carries various blanks or masks, one of which may be placed between supporting surface 9 and lower folder 33, so that visible parts of the originals can be projected onto selenium layer 1.
