The urging force of the spring 36 is prevented from reaching the rotating piece 34, and has an arcuate cam surface 56A concentric with the through hole 32C of the lever 32. The engaging operation between the cam 56 and the pin 54 will be described later.
[0020]
7A and 7B are explanatory views of the rotating piece 34. FIG. 7A is a top view and FIG. 7B is a side view. As shown in these drawings, the turning piece 34 is formed with the U-shaped groove 34A and the pin 54 described above. Further, as shown in FIG. 7A, the turning piece 34 has a through hole 34B formed at a substantially central portion thereof. Then, the light shielding door drive shaft 22 is fitted into the through hole 34B, and when the rotating piece 34 is rotated in the direction of arrow A in FIG. 1, the light shielding door opening / closing member 30 is rotated and the cartridge light shielding door 28 is rotated.

On the contrary, when the turning piece 34 is turned in the direction of arrow B in FIG. 1R> 1, the light shielding door opening / closing member 30 is turned in the reverse direction, and the cartridge light shielding door 28 is opened.
[0021]
The rotating piece 34 is urged toward one moving end side shown in FIG. 2 or the other moving end side shown in FIG. 5 by the urging force of the torsion coil spring 36 described above, and is not shown. The respective stoppers are stably positioned at their moving end positions. One end of the torsion coil spring 36 is locked to the pin 54 of the rotating piece 34, and the other end is locked to a fixing pin 58 on the apparatus main body side.
[0022]
Next, the operation of the driving force transmission mechanism 20 configured as described above will be described. The operation of the driving force transmission mechanism 20 shown in order in FIGS. 2 to 5 is an operation of first closing the cartridge light shielding door 28 and then opening the lid 4 of the cartridge chamber 2A. This operation will be described. First, when the film is completely wound on the spool 26 of the film cartridge 10, the motor 38 is driven in the counterclockwise direction in the drawing from the position shown in FIG. The driving force of the motor 38 is transmitted to the lever 32 through the gear 42A, the gear 44, the gear 46, and the gear 32A, and the lever 32 starts to rotate counterclockwise in the drawing. Then, the claw 32B of the lever 32 is engaged with the groove 34A of the rotating piece 34 as shown in FIG. 3, and the rotating piece 34 is rotated in the counterclockwise direction in FIG. 4 by pushing the groove 34A. Begin to. At this time, the rotating piece 34 rotates against the urging force of the torsion coil spring 36. With this urging force, the turning piece 34 tries to turn in the reverse direction (the original position shown in FIG. 2), but the pin 54 of the turning piece 34 moves the lever 32 as shown in FIGS. Since it is abutted against the ridge 52 and the return is restricted, it rotates smoothly without returning.
[0023]
When the lever 32 rotates to the position shown in FIG. 4, the urging force of the torsion coil spring 36 is switched to the other moving end direction side. Therefore, the turning piece 34 is turned at once toward the other moving end position by the biasing force of the torsion coil spring 36 that has been switched. However, the pin 54 of the torsional turning piece 34 comes into contact with the cam surface 56A of the cam 56 and stops there. In this state, the light blocking door 28 of the film cartridge 10 is closed, but if further lever 32 is rotated, the cam 56 escapes completely from the pin 54, the biasing force of Kaidokoma 34 torsion coil spring 36 Is rotated to the other moving end position. 1 is rotated in the direction of arrow A in the drawing, the cartridge light-shielding door 28 is reliably closed.
[0024]
Incidentally, the lock release lever 18 is not rotated in the range of rotation of the lever 32 shown in FIGS. During this time, one end of the lock release lever 18 slides in the cam groove 48A, so that the tip 18A of the lock release lever 18 is held at a position away from the end 12A of the lock lever 12, but the lever 32 thereafter rotates. By operation, one end portion of the lock release lever 18 slides in the deformed cam groove 48B shown in FIG. 6A to operate the lock release lever 18, and comes into contact with the end portion 12B of the lock lever 12, thereby The lever 12 is operated to open the lid 4.
[0025]
In the above embodiment, the closing operation of the light shielding door 28 and the opening operation of the lid 4 have been described. However, if the lever 32 is rotated in the order shown in FIGS. 5 to 2, the opening operation of the light shielding door 28 and the film feeding operation are performed. And can be done. Similarly, in this case, since the turning piece 34 is prevented from returning backward by the restricting member, it smoothly turns. The lever 32 is engaged with the spool drive shaft 24 shown in FIG. 10 after the engagement with the rotating piece 34 is released. The lever 32 rotates the spool 26 in the film feeding direction via the spool drive shaft 24. As a result, the film is sent out from the film cartridge 10.
[0026]
By the way, as shown in FIG. 8, the light shielding door drive shaft 22 receives the opening / closing member 30 of the film cartridge 10 in the region where the rotation angle is 209 ° ± 4 ° from the reference position, and the rotation angle is 117 ° ± 4 °. The cartridge light-shielding door 28 of the cartridge 10 is opened in this area, and the cartridge light-shielding door 28 of the cartridge 10 is closed in the area of the rotation angle of 209 ° ± 4 °, and the film cartridge 10 is discharged.
[0027]

It stops at the front rotation position (standby position). This standby position is a position at which the light shielding door opening / closing member 30 of the film cartridge 10 can follow the light shielding door drive shaft 22 even if the film cartridge 10 is loaded with the cartridge light shielding door 28 opened. It is. In the embodiment of the present invention, the standby position is preferably a rotation angle of 206 ° ± 1 ° (hereinafter referred to as B mode), and the closed position when the film cartridge is discharged is a rotation angle of 212 ° ± 1. The rotation operation of the light-shielding door drive shaft 22 is controlled so as to be at 0 ° (hereinafter referred to as A mode).
[0028]
Below, an example of the rotation operation | movement of the light shielding door drive shaft 22 is demonstrated based on the flowchart of FIG. When the power is turned on (step 101) and the eject button is operated (step 102), the lever 32 is rotated in one direction and the lid 4 of the cartridge chamber 2A is unlocked at the position shown in FIG. The lid 4 is opened (step 103).

When the film cartridge 10 is loaded into the cartridge chamber 2A (step 104) and confirmed (step 105), the lever 32 is rotated in one direction, whereby the light shielding door drive shaft 22 is moved to the A mode position, that is, as shown in FIG. 5, the pin 54 of the rotating piece 34 is rotated to a position where it is completely removed from the cam 56 of the lever 32, and the cartridge light shielding door 28 is once completely closed. When it is confirmed that the lid 4 of the cartridge chamber 2A is closed (step 106), the lever 32 is rotated in the other direction, and the light shielding door drive shaft 22 is rotated to open the cartridge light shielding door 28. (Step 107). This state is a state in which the turning piece 34 is turned to one end as shown in FIG. Next, the film is fed out from the film cartridge 10 and is reproduced (step 108). When the reproduction is finished, the eject button is operated (step 109). Then, the film is wound on the film cartridge 10. When it is confirmed that the film is caught in the film cartridge 10, the lever 32 is rotated in one direction, the light shielding door drive shaft 22 passes through the A mode position, and the rotation piece 34 as shown in FIG. The pin 54 is rotated to a position where it is completely removed from the cam surface 56A of the cam 56 of the lever 32 (step 110), and the lid 4 of the cartridge chamber 2A is opened. When it is confirmed that the lid 4 of the cartridge chamber 2A has been opened (step 111), the lever 32 is rotated in the other direction and returned to the A mode position, where the film cartridge 10 is discharged from the cartridge chamber 2A ( Step 112). When it is confirmed that the film cartridge 10 is discharged from the cartridge chamber 2A, the lever 32 is further rotated in the other direction, and the light shielding door drive shaft 22 is in the B mode position, that is, as shown in FIG. The pin 54 of the rotating piece 34 is rotated so as to be in contact with the cam surface 56 </ b> A of the cam 56 of the lever 32. Next, the lid 4 of the cartridge chamber 2A is closed (step 114). The light shielding door drive shaft 22 is on standby at this B mode position.
[0029]
The above-described procedure is merely an example. In the present invention, when the film cartridge 10 is received in the cartridge chamber 2A, the light shielding door drive shaft 22 is made to wait slightly before the closed position of the light shielding door 28. When the film cartridge 10 is discharged from the cartridge chamber 2A, other procedures may be appropriately changed as long as the light shielding door drive shaft 22 is held at the closed position of the light shielding door 28.
[0030]
