On the other hand, if no signal is obtained from the microswitch 78, the display circuit 113 is activated and a warning device 114 such as a display lamp or a buzzer displays a warning.

[Effect of the embodiment]

The action of the photo vending machine 20 having the above configuration is as follows:
It is as follows. First, a predetermined number of film packs 13 are loaded into the rack 85, and the photo vending machine 20 is ready for use. In addition, the first light shielding sheet 1
4 is manually ejected after loading the film pack 13. Further, the film pack 13 is pushed onto the base plate 3 by a pressing plate 47 provided on the bag 45.
It is pressed against the surface 35 of 0 so as to be optically dense. And the leaf spring 46 of the back 45
As a result, the film pack 13 is positioned at the scheduled photographing position.

In this way, after the photo vending machine 20 is ready for use, its operations are performed according to the flowchart shown in FIG. That is, when the coin insertion detection circuit 100 detects the insertion of a predetermined coin, the shutter circuit 101 is activated and photographing is performed after some preparation time. When photographing is completed, the unit drawer device 55 is activated in response to a signal from the shutter operation detection circuit 102. In conjunction with this, the solenoid 69 operates, and the distribution shutter 70
moves to the position indicated by the dashed dot line in FIG. Then, the driving roller 57, the driven roller 60, and the moving table 5
6 is lowered, the tab 6 is pulled out, and the pulled out tab 6 is collected in the waste box 71.

Thereafter, the sorting shutter 70 returns to the position shown in the solid line in FIG. 6, and the photographed photosensitive sheet 1 , image-receiving sheet 2 are pulled out through the developing roller 48 in the bag 45. The photosensitive sheet 1 and image receiving sheet 2 pulled out in this way are
The sheets 1 and 2 are discharged to the outlet 24 in a close contact state, and when the user peels off both sheets 1 and 2, a printed image can be obtained on the image receiving sheet 2.

The above operation is repeated in the same way up to nine times of imaging. When the tenth photograph is taken, the "10" count signal obtained from the counter 105 is delayed until the pulling out of the tenth film sheet 10 is completed, and then the drive circuits 107, 108 is output to. As a result, the motor 50 is driven and the support plate 40 moves backward, so that the bag 45 also moves backward. Therefore, the empty film pack 13 is left on the protrusion 36. At this time, due to the action of the pressing plate 47,
The empty film pack 13 does not move back together with the bag 45. At the same time, the motor 88
Due to the cycle drive, the rack 85 is moved forward by the thickness of one film pack, and a new film pack 13 is brought to a position where it is juxtaposed with the guide piece 37.

When the drive circuit 107 drives the motor 50 for half a cycle and the bag 45 is moved backward, the drive circuit 110 is activated. As a result, the motor 75
is driven to move the pack feed lever 76 to the left in FIG. Therefore, pack feed claw 7
7 feeds a new film pack 13 inward, and while pushing out the empty film pack to the guide piece 38, insert the new film pack 13 into the protrusion 3.
6. Place it on top. Empty film packs fall downward via the guide piece 38 and are collected in the waste box 71. Thereafter, when the rotation of the motor 50 reaches a predetermined amount, the bag 45 is moved forward, and the leaf springs 46,
The film pack 13 is pressed against the surface 3 through the pressing plate 47.
It is fixed at the shooting position pressed by 5.

When the pack feed lever 76 feeds a new film pack 13, the micro switch 78 comes into contact with the side of the film pack, and a pack detection signal is obtained there. This signal resets the count value of the counter 105 to "0" and operates the unit drawer device 55 after a period of time has passed until the new film pack 13 is securely fixed at the photographing position. When the unit drawer 55 is operated in this manner, the light-shielding sheet 15 (see FIGS. 1 and 8) of a new film pack 13 is pulled out, and preparations for subsequent photography are completed.

On the other hand, in the above operation, if no film pack detection signal is obtained from the micro switch 78, the warning device 114 is activated via the display circuit 113 to display a warning that the film pack needs to be replenished. Note that each part of the device may be configured to be locked at this point.

In the embodiment described above, the motors 50, 75, 8
A cam or a link mechanism may be used between the motor 8 and each interlocking member to convert the rotation of the motor into movement in a desired direction. In addition, the drive circuit for driving each motor is controlled by a microcomputer, etc., and the operating timing of each motor is controlled, and microswitches are controlled by interlocking members operated by each motor.
It is also possible to turn the motors ON and OFF and use the signals to perform sequence control of each motor.

In the above embodiment, the pack feed lever 76 is operated after the rack 85 is moved, but the same effect can be obtained even if the rack 85 is moved after a new film pack is fed by the pack feed lever 76. Functionality is obtained.

[Effect of idea]

As described above, according to the instant photography device of the present invention, the film pack for peel-apart film stored in the pack housing section can be kept in the attitude with the tab facing downward, and the tab can be moved while being fed. Since the lower surface of the film pack on the exposure aperture side is supported to prevent deformation, and the film packs are fed into the shooting position one after another, there is no need to manually replace film packs even with peel-apart type instant film units. Become. Therefore, the present invention is particularly effective when constructing an unmanned photographing device such as a photo vending machine or an interval photographing machine.
