Description

[0001]
[Industrial application fields]
The present invention relates to an improvement in a negative mask device of an automatic photo processor.
[0002]
[Prior art]
In recent years, a new type of film F has been proposed on the assumption that it is used while being connected to the spool shaft C1 of the cartridge C except during development processing. When such a film F is set and printed in a negative mask device of an automatic photo processor, a negative mask device 60 provided with a cartridge setting unit 61 with a thrust mechanism is required as shown in FIG.
[0003]
However, according to the flow of processing operations at a photo shop or the like, in the printing process after film development, it is better to print using a strip-state film (hereinafter referred to as “strip film”) f before being connected to the cartridge. It can be efficient. In this case, as shown in FIG. 6, when the strip film f is fed into the negative mask device 60, the thrust mechanism is obstructed and it is difficult to insert the film into the film insertion port 62 of the negative mask device 60. There was a problem that the film f was damaged.
[0004]
Therefore, as shown in FIG. 7, a negative mask device 70 dedicated to a strip film in which the cartridge setting unit is omitted is necessary, but there is a problem that the equipment burden of a photo shop or the like increases. Although it is conceivable that the film F stored in the cartridge C is processed by the negative mask device 70 dedicated to the strip film, since the negative mask device 70 is not provided with a thrust mechanism, the film F is fed into the film insertion port 71. In addition, when only the front end of the film F is manually pulled out from the cartridge C and fed into the film insertion port 71, the rear end of the film F is connected to the spool shaft C1 of the cartridge C. There was a problem that the conveyance resistance of the film F was increased and the film F was damaged.
[0005]
[Problems to be solved by the invention]
The present invention has been made in view of the above points, and an object of the present invention is to feed a strip film into a film insertion opening without being obstructed by the cartridge setting portion in an apparatus having the cartridge setting portion. An object of the present invention is to provide a negative mask device for an automatic photo processor.
