That is, the coupling member 68 and the coupled member 69 form holding means for temporarily holding the film cassette 1. Other configurations are the same as those of the above-described conventional endoscope camera, for example, the one disclosed in Japanese Patent Publication No. 61-8420. Therefore, description of the detailed configuration is omitted here.

Next, the operation of loading the endoscope film cassette 1 configured as described above into the endoscope camera 6 and taking out the cassette 1 from the camera 6 will be described. This will be described below. FIGS. 2 and 3 are a vertical sectional view and a horizontal sectional view of a main part showing a part of an endoscope camera 6 using the endoscope film cassette 1.

As shown in FIGS. 2 and 3, a cassette storage chamber 7 for storing the endoscope film cassette 1 in which the photographic film 5 is wound and stored is provided inside the endoscope camera 6. The storage room 7 is open on the back side of the main body of the camera 6. The opening on the back side is openable and closable by the turning operation of the opening / closing lid 9 rotatably supported by the support shaft 37.

When the opening / closing lid 9 is rotated in the opening direction (the state shown by the two-dot chain line in FIG. 2), the back side opening of the cassette storage chamber 7 is opened, and the film cassette 1 is moved to the cassette storage chamber 7. It is in a state where it can be loaded inside (see FIG. 1).

In this state, when the film cassette 1 is loaded at a predetermined position in the cassette storage chamber 7 and the opening / closing lid 9 is rotated in the closing direction to bring it into the closed state (the state shown by the solid line in FIG. 2). A pressing portion 53 provided on the inner wall surface side of the opening / closing lid 9 presses a hook 54 provided at one end of the lock lever 51. Thereby, the lock lever 5
1 rotates clockwise against the urging force of the urging spring 52. Then, the engaging portion 55 provided on the other arm end of the lock lever 51 is disengaged from the engaging step portion 49 of the slide plate 39. Therefore, the lock lever 51 is positioned at the position shown by the solid line in FIG.

When the opening / closing lid 9 is completely closed in this manner, the connecting member 6 attached to the inner wall surface of the opening / closing lid 9 is opened.

The rack 64 rotates the pinion 57 meshing with the rack 64 in a clockwise direction (the direction of the arrow X2 in FIG. 3) as viewed from the rear side of the camera 6. Since the pinion 57 is engaged with a rack 58 provided at the upper end of the slide plate 39, the slide plate 3 is connected via the rack 58.
9 is moved downward of the camera 6 against the urging force of the urging spring 44. As a result, the push-up pin 45 also descends, so that the inner cylinder 21 of the film cassette 1 descends by the urging force of the urging spring 33, and thus the engaging claw 26 and the claw 47 of the film winding shaft 46 come into contact with each other. Is disengaged. The upper surface of the inner cylinder 21 is covered with the outer cylinder 22 and the lid member 1.
5 returns to the normal state in which the upper surface is the same as the upper surface.

In this state, the opening / closing lid 9 is attached to the support shaft 3.
When the lock lever 51 is rotated about the fulcrum to be in the open state, the lock lever 51 rotates counterclockwise in FIG. 2 by the urging force of the urging spring 52, and the engaging portion 55 of the lock lever 51 Engage with the part 49. Thereby, the slide plate 39 is stopped at the lowered position. Therefore, the film cassette 1 can be taken out from the cassette storage chamber 7 to the rear side of the camera 6. At this time, the to-be-coupled member 69 provided on the back of the film cassette 1
The connecting member 68 provided on the inner wall surface of the opening / closing lid 9 is in a connected state. Therefore, the film cassette 1 is discharged from the cassette storage chamber 7 with the rotation of the open / close lid 9 to the open state. Then, the operator removes the film cassette 1 stuck to the opening / closing lid 9 against the coupling force of the coupling member 68 and the coupled member 69, thereby ensuring that the film cassette 1 is not dropped. Can be taken out.
