The carrying mechanism of strip film (A) is located at the second guide in the movable side and unified into one body. The first guide located at the way from the photographic sensor ([0056] 60) of the picture of stripfilm (A) or slid mount (B) to the path. The distance of the scanner (63) of the photographic sensor (60) is minimized, therefore, the body of the device is getting smaller.
[The Scanning Operation of the Slide Mount][0057]
Next will be the scanning of the slide mount (B). The slide mount (B) is connected to the first guide ([0058] 51) from the third opening (50).
As for the insertion of slide mount (B), the view from upper part of the first opening ([0059] 11) of cover is able to judge the existence and the right position of the insertion, therefore, an identified sensor is not really necessary, it getting better of course.
The scanning is started automatically when the slid mount (B) is carried to the location in accordance with the position of two light path ([0060] 21) and (31). It is possible operated by man after the scanning is started.
[Effect][0061]
Neither the stripfilm nor slide mount is need a special scanner device. The scanning is going at the insertion of operation from the first or the second opening. [0062]
The same photographic sensor is used for scanning even the thickness of the stripfilm and slid mount is different. Therefore, the whole body of present invention is getting small. [0063]
