Since the urging force of the spring 33 is sufficiently smaller than the force of the film 25 sent out to push the film detection lever 10, the film 25 is moved by the film detection lever 1
Even if the film detection lever 10 comes into contact with 0, the movement is not hindered, the film detection lever 10 is rotated clockwise in FIG. 17, and then further fed (see FIG. 18).

When the film detection portion 10a of the film detection lever 10 is pushed out of the film feeding path 32 by the film 25, the locking portion 10b at the other end also rotates integrally, and the first transmission member 11 of the first transmission member 11 is rotated. It engages with the engaging portion 11e.

When the film 25 is coming out of the film cartridge 1, the film detecting section 10a of the film detecting lever 10 detects the presence of the film 25, and at this time, the locking section 10b is the engaging section of the first transmission member 11. 11e
Is always engaged.

In this state, if the knob portion 9c of the locking member 9 is moved to the upper side of the camera in order to open the cartridge cover 5, the locking member 9 has a U-shaped engaging portion 9c.
e and the boss 11c of the first arm 11a of the first transmission member 11.
Are engaged, the first transmission member 11 tries to rotate counterclockwise in FIG. 15 about the shaft 11f as a rotation center.

However, the second arm 1 of the first transmission member 11
Since the engagement portion 11e of 1b is engaged with the locking portion 10b of the film detection lever 10, the first transmission member 11 cannot rotate.

As a result, the boss 11 of the second lever 11b is
The second transmission member 12 engaged with d does not move either, and the engagement between the boss 6b of the light-shielding lid opening / closing member 6 and the second contact surface 12d of the second transmission member 12 is not released, and thus the light shielding is performed. Since the lid opening / closing member 6 does not rotate, the light shielding lid 2 of the film cartridge 1 does not close.

In other words, even if the patrone cover 5 is opened while the film 25 is pulled out from the film patrone 1, the locking portion 10 of the film detecting lever 10 is opened.
Since only a slight gap (that is, a so-called backlash) can be moved between b and the engaging portion 11e of the first transmission member 11, the engaging portion 9a of the engaging member 9 and the cartridge cover 5 can be moved. The engagement of the engaging portion 5a is not released, and therefore the patrone lid 5 is not opened.

On the other hand, the light-blocking lid opening / closing member 6 cannot rotate because the boss 6b is locked to the second contact surface 12d of the second transmitting member 12, so that the light-blocking lid 2 of the film cartridge 1 is also opened. Never close (Figs. 15 and 1)
6).

In this state, the knob 9 of the locking member 9
When a force is applied to forcefully lift c, the first transmission member 11 tries to rotate counterclockwise in FIG. 15 about the shaft 11f, so that the engaging portion 11e of the second arm 11b moves to the film detection lever 10c. The locking portion 10b of is pressed downward in FIG. Since this force is not a force applied to the film 25, even if the photographer accidentally tries to move the knob 9c of the locking member 9 upward, the film 25
Does not hurt or hurt.

Next, the operation of opening the cartridge cover 5 will be described. When the shooting of all the frames of the film 25 stored in the loaded film cartridge 1 is completed, the CPU drives a motor (not shown) so as to rotate the sun gear 21 in the direction of arrow R in FIG. .

When the sun gear 21 rotates in the direction of arrow R in FIG. 16, the planetary gear 23 revolves around the sun gear 21 in the direction of arrow R and meshes with the gear 16b of the drive shaft 16 to drive the drive shaft 16. Rotate in the direction of arrow R.

The drive shaft 16 is used for the film cartridge 1.
The film 25 is wound into the film cartridge 1 because it is engaged with the cartridge pool 3 of FIG.

When the film 25 is rewound and the film 25 no longer exists in the film feeding path 32, the film detecting lever 10 is moved by the urging force of the spring 33 as shown in FIG.
(A) The film detector 1 is rotated counterclockwise in the middle direction.
0a projects into the film feed path 32 (see FIG. 17).

When the film detecting lever 10 rotates, the engaging portion 1b between the engaging portion 10b and the first transmitting member 11 is rotated.
The engagement with 1e is released (see FIGS. 17 and 13).

In this state, the photographer slides the knob 9c of the locking member 9 exposed to the outside of the camera body 4 upward.

As the locking member 9 moves upward, the first transmission member 11 engaged with the engaging portion 9e of the engaging member 9e becomes the shaft 11
It is rotated counterclockwise in FIG. 13 with f as the center of rotation.

Locking portion 10b of the film detecting lever 10
As described above, the engaging portion 1 of the first transmission member 11 has already been
Since the engagement with 1e is released, the first transmission member 1
1 is in a state of being rotatable about a shaft 11f as a rotation center.

The first transmission member 11 and the second transmission member 12 are
Since the boss 11d and the engaging portion 12b are engaged with each other, the rotational movement of the first transmission member 11 is caused by the rotation of the second transmission member 12.
Transmitted as a sliding movement to. That is, the second transmission member 12 slides and moves to the right in FIGS. 13 and 14.

The light-blocking lid opening / closing member 6 is biased counterclockwise in FIG. 14 by the biasing force of the spring 28.
Does not rotate because is still locked to the second contact surface 12d of the second transmission member 12.

Even if the second transmission member 12 moves to the right,
Since the positional relationship between the second contact surface 12d and the boss 6b of the light shielding lid opening / closing member 6 does not change for a while, the locking is not released and the light shielding lid opening / closing member 6 does not rotate (FIGS. 11 to 14).
reference).

When the knob 9c of the locking member 9 is slid further upward, the second transmission member 12 is also slid further rightward in FIGS. 11 and 12.

By sliding the second transmission member 12,
The second contact surface 12d is no longer the boss 6b of the light-shielding lid opening / closing member 6.
10 cannot be locked, the light-blocking lid opening / closing member 6 rotates counterclockwise in FIG. 10 by the urging force of the spring 28, and rotates until the boss 6b contacts the first contact surface 12c of the second transmission member 12. (See FIGS. 9 and 10).

By sliding the locking member 9 further upward, the second transmission member 12 is further moved to the right in FIGS. 9 and 10, and the light-shielding lid opening / closing member 6 also moves the boss 6b to the second transmission member 12. In the state of being brought into contact with the first contact surface 12c of the above, it rotates counterclockwise in FIG. 10 along with the second transmission member 12.

The arm 6c of the light-shielding lid opening / closing member 6 serves as a positioning boss 3 for the bottom plate 26b of the film cartridge loading chamber 26.
When it comes into contact with 1, the light shielding lid opening / closing member 6 stops its rotation. At this position, the light shielding lid 2 of the film cartridge 1 is completely closed.

In this state, the light-shielding lid 2 of the film cartridge 1 is completely closed, but the locking portion 9a of the locking member 9 is closed.
Since the engagement with the engaging portion 5a of the cartridge cover 5 has not been released yet, the knob 9c of the locking member 9 is further raised (see FIGS. 7 and 8).

By sliding the knob 9c of the locking member 9 upward, the engagement between the locking portion 9a and the engaging portion 5a of the cartridge cover 5 is released, and at the same time, the locking arm 9d of the locking member 9 is released. Engages with the locking portion of the camera body 4 not shown,
