(The film cassette C is provided in a portion exposed to the outside when the film cassette C is inserted into the film cassette storage section H.) After unlocking the lock N, the magazine knob N is pulled forward to open the shutter S. I do. When the photographing is completed and the film cassette C is pulled out, the magazine knob N is pushed out toward the photographing device to close the shutter S. When the shutter S is closed, a spring of the lock L (not shown)
, The lock L resiliently returns to the original position, and the magazine knob N is locked.

As described above, conventionally, when mounting and removing the film cassette C, the user has to operate the magazine knob N to open and close the shutter S, which causes a problem that the operation is complicated.

[0004] In addition, since it is necessary to operate the magazine knob N,
Since the film cassette C protrudes from the photo reproducing device,
There is also a problem that the photo reproducing apparatus cannot be made compact and its appearance is poor.

[0005]

A rotatable lever mainly including a mold-shaped opening / closing operation member, a first spring member 64, and a second spring member 65.
It is a form. That is, as shown in FIG.
The mechanism 6 is configured to be rotatable about a holding shaft 81.
Have been. This rotatable form is a film supply cassette
According to the insertion direction side surface 32 of FIG.
-It will be in the form.

More specifically, a holding shaft 81 of the holding member 8 penetrates a substantially central portion of the second member 62, whereby the second member 62 can rotate around the holding shaft 81. . Near the end of the second member 62 on the cassette insertion port side, an end of the third member 63 is attached rotatably about a shaft 63b . The end of the first member 61 is slidable near the opposite end of the second member 62.
It is stuck to. The first member 61 and the second member 61
In a state where the member 62 and the third member 63 are connected, the first opening / closing mechanism 6 has an arcuate shape open to the cassette side as shown in FIG. In this bowed state, the distal end portion 61a of the first member is projected to a position where it comes into contact with the distal end corner portion 31 of the film supply cassette 3. The amount of protrusion is adjusted by a stopper 66 abutting on the first member 61 inside the first opening / closing mechanism 6 having an arc shape. Also, the third
The distal end 63a of the member 63 is
The shutter opening / closing member N protrudes to a position where the shutter opening / closing member N comes into contact with the guide portion N2. The amount of protrusion is the third member of the second member 62.
It is adjusted by a set screw 62a provided at a position where the member is attached.

Further, for smooth operation of the first opening / closing mechanism 6, the first opening / closing mechanism 6 having an arcuate shape is provided inside the first opening / closing mechanism 6.
A spring member 64 and a second spring member 65 are provided. One end of the first spring member 64 is locked by the first member 61, and the other end is locked by a locking piece 82 provided on the holding member 8. On the other hand, one end of the second spring member 65 is connected to the second member 6.
2 is locked by a locking piece 62 b provided on the second member 2, and the other end is locked by a third member 63. In addition, the contents of the smooth operation
Will be described later.

By the way, in this embodiment, first member 61
The side surface 32 of the film supply cassette 3 is
In order to facilitate sliding on the top, a rotating member 67 is attached as shown in FIG.
An engaging member 68 made of a material having a large frictional resistance, such as urethane, is attached to the front end portion 63a so that the front end portion 63a can firmly engage with the shutter opening / closing member N.

The second opening / closing mechanism 7 is also a rotatable lever type having a first member 71, a second member 72, a third member 73, a first spring member 74 and a second spring member 75 as main components.
State . The connection relationship and operation of these components are the same as those of the first opening / closing member 6. Therefore, here, the drawing of the second opening / closing mechanism 7 corresponding to FIG. 6 is not particularly shown, and FIG. 6 for the first opening / closing mechanism 6 is applied mutatis mutandis.

Next, the opening and closing of the shutter S in the film cassette mechanism configured as described above will be described with reference to the first opening and closing mechanism 6 as an example, with reference to FIGS. In FIG. 5, the shutter S of the film supply cassette 3 is closed, and the shutter S of the film collection cassette 4 is open.

Irradiation) is set to be larger than the step b of the top portion of the guiding portion N2 and the bottom of the engagement recess N1 of the shutter opening and closing member N (see Figure 9). Therefore, the force is proportional to both the difference (a-b) engaging recess N1 is the third member 63 tip 63
It is pressed by the engaging member 68 attached to the “a” . For this reason, the shutter opening / closing member N is located at that position ,
It will remain at the position of engagement with the engagement member 68 . In Figure 5, rotation of first member 61 of the first opening and closing mechanism 6 is rotated in the direction of the arrow in the figure is attached to the distal end 61a
The member 67 is the side surface 32 of the film supply cassette 3 in the insertion direction.
And attached to the distal end portion 63a of the third member 63.
The engaged engaging member 68 engages with the engaging concave portion N1 of the shutter opening / closing member N.

Thereafter, the insertion (movement in the direction of the arrow in FIG. 5) of the film supply cassette 3 is continued .
As described above, since the movement of the shutter opening / closing member N in the insertion direction is restricted by the pressing force of the engaging member 68 attached to the distal end portion 63a of the first opening / closing mechanism 6 , the main body of the film supply cassette 3 is (Film storage section) Only C1 moves into the insertion opening 21 of the cassette storage section 2 . On the other hand, the shutter S integrated with the opening / closing member N stays there. Therefore, the shutter S is in phase with the main body C1.

Although the present invention has been described based on the embodiments, the present invention is not limited to the above-described embodiments, and the design can be appropriately changed.

For example, in the present embodiment, the opening / closing mechanism is mechanically configured using a link mechanism. However, the opening / closing mechanism can be electrically configured by combining a limit switch and a step motor.

[0034]

As described above, according to the present invention,
Since the shutter is automatically opened and closed when the film cassette is mounted and demounted, the operation can be simplified. Further, since the shutter opening / closing mechanism is provided in the storage portion of the film cassette, the projection of the film cassette from the photo reproducing device can be minimized, so that the photo reproducing device can be made compact.

In the film cassette used in the present invention, the lock mechanism conventionally used is not required, so that the film cassette can be made compact and
Manufacturing costs can be reduced.
