Abstract
Description
- 1. Field of Invention
- The present invention generally relates to a device for adjusting the position of a platform of a scanner, and more particularly relates to an adjusting device for a flatbed scanner. The device can precisely adjust the height of the platform so as to calibrate the depth of field of the scanner.
- 2. Related Art
- Flatbed scanners have been the mainstream of scanners as peripheral devices of computers. Manufacturing processes for flatbed scanners are of known arts.
- As shown in FIG. 1, a flatbed scanner mainly includes a
lower case 76 having an opto-mechanic module 75 mounted therein; anupper case 70 mounted on thelower case 76; and aplatform 77 mounted on theupper case 70 for carrying the materials (such as documents or photos, not shown) to be scanned. Theplatform 77 is usually a transparent glass plate supported by a frame of theupper case 70. Theplatform 77 enables the scanned material to be scanned by the opto-mechanic module 75. In order to ensure good imaging, i.e., a suitable depth of field, the distance between the surface ofplatform 77 and the opto-mechanic module 75 must be well calibrated. An earlier method for calibrating the optical distance of the surface ofplatform 77 to the opto-mechanic module 75 is to test scanning and find out the correct position before fixing theplatform 77 to the case. The process is rather bothersome. - An adjusting device is further shown in FIG. 1, which is disclosed by Taiwan Laidopen Patent No. 361,756. The platform adjusting device includes a
screw hole 71 formed on theupper case 70 who has aplatform 77; and ahollow screw 73 engaged with thescrew hole 71. Thehollow screw 73 has a lower end stands on asupport plate 72 that is fixed to thelower case 76 of scanner. Finally, afastening screw 74 passing through thehollow screw 73 will fasten theupper case 70 and theplatform 77 to thesupport plate 72, and fix these elements. When thefastening screw 74 was removed, the height of theplatform 77 to thesupport plate 72 could be adjusting by turn thehollow screw 73. - In the aforesaid adjusting device, the
fastening screw 74 passing through the center hole of thehollow screw 73 to fasten the elements will hinder thetop 78 of thehollow screw 73 where a fastening tool will apply to. So, it is inconvenient that thefastening screw 74 has to be removed from the device before adjusting thehollow screw 73. Therefore, it will be quiet bothersome for re-adjusting the height of the platform that thefastening screw 74 has to be removed since there are usually four adjusting devices at the four comers of the platform. Also, the screws are easy to lose. Furthermore, the adjusting devices are based on the support plates that are weak in structure and cause insufficient support to the platform. - It is therefore an object of the present invention to provide an adjusting device for platform of scanner that can be easily used.
- Another object of the present invention is to provide an adjusting device for platform of scanner that is simple in structure and easy to be used.
- To achieve the aforesaid object, an adjusting device for platform of scanner according to the present invention mainly includes an exposed driving element for moving a supporting element of the platform. By first releasing a fastening screw, then turning with fingers the driving element from an exposed portion outside of the case, the position of the platform can be adjusted.
- In a first embodiment of the present invention, an adjusting device for platform of scanner includes a nut incorporated with an exposed flange for turning, and a stud fixed on the lower base. The nut rotatively engaged on the stud to move vertically and adjust the height of the platform that is supported on the nut.
- In a second embodiment of the present invention, an adjusting device for platform of scanner includes a driving slant element movably mounted on the lower case and activated by a screw exposed outwards; and a driven portion formed on the upper case that support the platform. By the function of the slant, the upper case and platform will be moved upward or downward to adjust its position according to a horizontal movement of the driving slant element.
- Further scope of applicability of the present invention will become apparent from the detailed description given hereinafter. However, it should be understood that the detailed description and specific examples, while indicating preferred embodiments of the invention, are given by way of illustration only, since various changes and modifications within the spirit and scope of the invention will become apparent to those skilled in the art from this detailed description.
- The present invention will become more fully understood from the detailed description given hereinbelow illustration only, and thus are not limitative of the present invention, and wherein:
- FIG. 1 is a sectional view of a prior art of adjusting device for platform of a scanner;
- FIG. 2 is a sectional view of an adjusting device for platform of scanner as a first embodiment of the present invention;
- FIGS. 3A, 3B are functional views of the first embodiment of the present invention showing operation of the adjusting device;
- FIG. 4 is a sectional view of an adjusting device for platform of scanner as a second embodiment of the present invention; and
- FIGS. 5A, 5B are functional views of the second embodiment of the present invention showing operation of the adjusting device.
- As shown in FIG. 2, a flatbed scanner mainly includes a
lower case 11 having an opto-mechanic module 10 mounted therein; anupper case 20 mounted on thelower case 11; and aplatform 30 mounted on theupper case 20 for carrying the materials (such as documents or photos, not shown) to be scanned. Theplatform 30 is usually a transparent glass plate supported by a frame of theupper case 20 and fixed therewith by embedding or glue. Theplatform 30 enables the scanned material to be scanned by the opto-mechanic module 10. In order to ensure good imaging, i.e., obtain a suitable depth of field D, the distance between the surface ofplatform 30 and the opto-mechanic module 10 must be well calibrated. In other words, theplatform 30 must be well positioned in parallel to the opto-mechanic module 10 and keep a suitable distance for clear images detected by the movable opto-mechanic module 10. - An adjusting device for platform of scanner according to the present invention mainly includes an exposed driving element for moving a supporting element of the
platform 30. By turning with fingers the driving element from an exposed portion outside the case, the position of theplatform 30 can be adjusted. - In a first embodiment of the present invention, as shown in FIG. 2, an
adjusting device 40 for platform of a scanner includes annut 41 incorporated with an exposedflange 42 for turning, and astud 12 fixed to thelower base 11 via asupport 13. Thenut 41 rotatively engaged on thestud 12 to move vertically and adjust the height of theplatform 30 that is supported on thenut 41 through theupper case 20. Thestud 12 is fixed with its bottom end to thesupport 13. An outer screw is formed outside thestud 12 for engaging with thenut 41. Aninner screw 120 is also formed in a inside wall of thestud 12 for engaging with a fasteningscrew 21 a. Theflange 42 of thenut 41 exposes outside thecase flange 42 andnut 41 will move the upper surface of thenut 41 upwards or downwards and adjust theupper case 11, as well as theplatform 30, to a suitable height relative to the opto-mechanic module 10. After the adjustment, the fastening screw 21 a engaging into theinner screw 120 of thestud 12 will fasten theupper case 11 and theplatform 30 in place. - As shown in FIGS. 3A, 3B, when adjusting the
device 40, thefastening screw 21 a is first released (but need not be removed), especially when theplatform 30 is to be adjusted upwards. Then, theflange 42 ofnut 41 is rotated by user to move vertically along the axial direction of thestud 12, and adjust the height of theupper case 20 andplatform 30. After a suitable position is obtained, thefastening screw 21 a can be fastened again to fix the device. The head portion of thefastening screw 21 a can further be glued to theupper case 20 to prevent the elements from being moved. - FIG. 4 shows a second embodiment of the present invention. The adjusting device for platform of scanner includes a driving
slant element 60 movably mounted on thelower case 11 and activated by ascrew 50 exposed outwards; and a drivenportion 62 formed on the upper case that support theplatform 30. By the finction of theslant element 60, theupper case 20 andplatform 30 will be moved upward or downward to adjust its position according to a horizontal movement of the drivingslant element 60. In detail, thescrew 50 is rotatively mounted on asupport 13 fixed on thelower case 11. The drivingslant element 60 seating on thesupport 13 is movable by thescrew 50 engaging on a screw hole formed on side of the drivingslant element 60. Afirst slant 61 is formed on top of the drivingslant element 60 to contact the drivenportion 62 fixed or formed on theupper case 20. The drivenportion 62 is preferably formed with asecond slant 620 to match with thefirst slant 61 of the drivingslant element 60. The drivingslant element 60 is preferably formed with a throughhole 600 having a long slot cross-section to be passed by afastening screw 21 b and guided thereby during moving. After the height of theplatform 30 is settled, thefastening screw 21 b is fastened to thesupport 13 to fix theupper case 20 through fixing the drivenportion 62 and the drivingslant element 60. - As shown in FIGS. 5A, 5B, when adjusting the device, the
fastening screw 21 b is first released (but need not be removed), especially when theplatform 30 is to be adjusted upwards. Then, thescrew 50 is rotated by user to horizontally move the drivingslant element 60. The height of theupper case 20 andplatform 30 can then be adjusted through the vertical movement of the drivenportion 62 caused by movement of the drivingslant element 60. After a suitable height is obtained, thefastening screw 21 b can be fastened again to fix the device. The head portion of thefastening screw 21 b can further be glued to theupper case 20 to prevent the elements from being moved. - The invention being thus described, it will be obvious that the same may be varied in many ways. Such variations are not to be regarded as a departure from the spirit and scope of the invention, and all such modifications as would be obvious to one skilled in the art are intended to be included within the scope of the following claims.
