Consequently, strip film (A) is moved to the exit between roller (34) and the idling roller (24) of the press plate (2).

The carrying is stop by the signal of location sensor (D2) when the strip film (a) is positioned, means the first light path (4) of the cover (1), the second light path (21) of supporting plate (2) and the third light path (31) are at the same position.

The scanning is conducted when the position of the strip film (a) is in accordance with the two light paths (21), (31), the light from the light source (62) is transmitted through two light path (21), (31) and the strip film (A).

The scanning of the coma of the whole strip film (A) is over so far. The exit sensor (D3) is located at the supporting plate (3), the detected signal from the end of the strip film (A) is transmitted to the motor (37), The scanning of the strip film (A) is over because the motor (37) was stop working.

The operation was shown in FIG. 6, the partial thickness inside the second opening (12) and the first opening (11) of the cover (1), is embedded to the end cutting (41) of the carrying path (42), the right position relation between the cover (1) and press plate (2) is maintained even the vibration is happened.

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 (60) of the picture of strip film (A) or slid mount (B) to the path. The distance of the scanner (63) of the photographic sensor (60) are minimized, therefore, the body of the device is getting smaller.

The Scanning Operation of the Slid Mount

Next will be the scanning of the slid mount (B) the slid mount (B) is connected to the first guide (51) from the third opening (50).

As for the insertion of slid mount (B), the view from upper part of the first opening (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 (21) and (31). It is possible operated by man after the scanning is started.

Effect

Neither the strip film nor slid mount is need a special scanner device. The scanning is going at the insertion of operation from the first or the second opening.

The same photographic sensor is used for scanning even the thickness of the strip film and slid mount is different. Therefore, the whole body of present invention is getting small.
