The operation of the above-configured drive mechanism of the camera according to the present embodiment will be described below.

<Operating Door Closing Operation> When it is recognized that the operator has pressed the eject button (not shown) to load the film cartridge 1 into the camera, the operation shown in FIG. 6 starts. In step S1 of FIG. 6, the state of the light shielding door of the film cartridge 1 is read. If it is determined that the light shielding door is closed, the process proceeds to step S3. If it is determined that the light shielding door is not closed, the process proceeds to step S2. In step S2, the film feeding motor M is rotated in the winding direction of the film F.

When the motor M is rotated in the winding direction of the film F in step S2, the rotational force of the motor M is transmitted through the reduction gear train, the gear 31b, and the shaft member 31a, and the sun gear 31 and the sun gear 51 are moved in FIG. Rotate in the direction of the white arrow (clockwise).

In response to the rotation of the sun gear 31, the rewind planetary gear 33 and the hoisting planetary gear 34 rotate counterclockwise, and the first planetary lever 32 starts rotating clockwise. However, as shown in FIG. 1, the switching locking lever 42 pushed by the cam surface 41a is at a position rotated counterclockwise against the urging force of the urging spring 42b,
The contact portion 32a of the first planetary lever 32 and the switching locking lever 4
The second abutment portion 42b abuts, and the rotation of the first planetary lever 32 stops at that position. Therefore, the hoisting planet gear 3
4 does not mesh with the fork gear 35 and the cartridge fork shaft 11 does not rotate. That is, the film is not fed.

On the other hand, the driving planetary gear 53 rotates counterclockwise in response to the rotation of the sun gear 51, and the second planetary lever 52 rotates clockwise. In the state shown in FIG. 1 in which the switching locking lever 42 rotates counterclockwise, the contact portion 52a of the second planetary lever 52 does not contact the contact portion 42b of the switching locking lever 42, and the driving planetary gear The second planetary lever 52 rotates until 53 engages with one rotation gear 55. Therefore, the one-turn gear 55 rotates clockwise.

When the one-rotation gear 55 rotates, the light-shielding door drive lever 56 rotates clockwise about a rotation shaft 56c. With the rotation of the light shielding door drive lever 56, the light shielding door driving member 57 rotates clockwise as shown in FIG. 1, so that the light shielding door opening / closing shaft 12 rotates and the light shielding door of the film cartridge 1 is closed. . When it is detected in step S1 of FIG. 6 that the light shielding door is closed, step S1 is performed.
At 3, the rotation of the motor M is stopped. As a result, the light shielding door is maintained in the closed state. At this time, the light shielding door driving lever 56 comes to the position shown by the solid line in FIG.

<Cartridge Chamber Lid Opening Operation> Next, FIG.
In step S4, the state of the cartridge chamber lid 21 is read. If it is determined that the cartridge chamber lid 21 is in the open state, the process proceeds to step S6, where the cartridge chamber lid 21 is read.
If it is determined that is not in the open state, the process proceeds to step S5.

In step S5, the motor M is rotated in the direction of rewinding the film F. When the motor M rotates, the sun gear 31 and the sun gear 51 rotate counterclockwise as shown in FIG. In addition, the rewind planetary gear 33 and the hoisting planetary gear 34 rotate clockwise in accordance with the rotation of the sun gear 31, and the first planetary lever 32 rotates counterclockwise. However, since the light shielding door driving lever 56 is maintained at the position shown by the solid line in FIG. 2 rotated clockwise, the locking portion 32b of the rotating first planetary lever 32 is engaged with the light shielding door driving lever 56. The first planetary lever 32 stops rotating at that position. For this reason, the rewind planetary gear 33 does not mesh with the fork gear 35, and the film is not fed.

On the other hand, the driving planetary gear 53 rotates clockwise in accordance with the rotation of the sun gear 51, and the second planetary lever 5
2 rotates counterclockwise. Light shielding door drive lever 56
2, the second planetary lever 52 rotates counterclockwise without contacting the light-shielding door drive lever 56, so that the drive planetary gear 53 is rotated by the film cartridge chamber opening gear. The film cartridge chamber opening gear 61 rotates in the counterclockwise direction.

When the film cartridge opening gear 61 rotates, the projection 61a pushes the upper end portion 62a of the cartridge chamber opening drive lever 62 rightward in FIG.
The cartridge chamber opening drive lever 62 rotates, and the lower end 6
2b pushes the key board 22 to the left via the projection 22a of the key board 22. As a result, the key plate 22 moves in the P direction against the urging force of the urging spring 22c.
2b is disengaged from the locking claw 21b of the cartridge chamber lid 21, and the cartridge chamber lid 21 is opened.

As described above, the state of the cartridge chamber lid 21 is read in step S4 of FIG. 6, and if it is determined that the cartridge chamber lid 21 is in the open state, the process proceeds to step S6 and the rotation of the motor M is stopped. Then, the cartridge chamber lid 21 is kept open, and a new film cartridge 1 can be loaded.

<Light-shielding door opening operation> Next, step S in FIG.
7, it is determined whether or not the film cartridge 1 has been loaded in the cartridge chamber. If it is determined that the film cartridge 1 has been loaded, the process proceeds to step S11 in FIG. 7. If the film cartridge 1 has not been loaded for a predetermined time, the sequence ends. I do.

If the loading of the film cartridge 1 is detected in step S7, the process proceeds to step S12 after waiting for the detection that the cartridge chamber lid 21 is closed in step S11 in FIG. Step S1
In step 2, it is determined whether or not the light shielding door of the film cartridge 1 is open.
If it is determined that the light blocking door is not open, the process proceeds to step S13. In step S13, the motor M is rotated in the winding direction of the film F.

When the motor M is rotated in the winding direction, FIG.
Similarly, the sun gear 31 and the sun gear 51 rotate clockwise, and the second planetary lever 52 rotates clockwise. As a result, the driving planetary gear 53 meshes with the one-rotation gear 55, so that the one-rotation gear 55 rotates clockwise, and the light-shielding door driving lever 56 engaged with the driving pin 55a of the one-rotation gear 55 swings. The light-shielding door drive member 57 and the light-shielding door opening / closing shaft 12 rotate in accordance with the swing of the light-shielding door drive lever 56, and the light-shielding door drive lever 56 has moved to the position shown in FIG. 1 (the position shown by the dotted line in FIG. 2). When
The light blocking door of the film cartridge 1 reaches the open position.

If it is detected in step S12 in FIG. 7 that the light shielding door is opened, the process proceeds to step S14, in which the rotation of the motor M is stopped. As a result, the light shielding door of the film cartridge 1 is maintained at the open position.

<Data reading operation of data disk> After the light shielding door of the film cartridge 1 is opened, step S1 is executed.
In step 5, it is determined whether the reading of the data of the data disk of the film F has been completed. If it is determined that the reading of the data has already been completed, the process proceeds to step S17, and it is determined that the reading of the data has not been completed. If step S
Proceed to 16. In step S16, the motor M is set to the film F
Rotate in the rewind direction.

When the motor M is rotated in the rewinding direction, FIG.
, The sun gear 31 and the sun gear 51 rotate counterclockwise, and the first planetary lever 32 and the second planetary lever 52 rotate counterclockwise. Since the light-shielding door drive lever 56 is in the position shown in FIG. 3 (the position shown by the dotted line in FIG. 2) rotated clockwise, the first planetary lever 32
Rotates without contacting the locking portion 56 d, and the rewind planetary gear 33 meshes with the fork gear 35. Since the rewind planetary gear 33 rotates clockwise, the fork gear 35 rotates counterclockwise, and the data disk rotating integrally with the cartridge fork shaft 11 is also in the same direction (rewind direction of the film F). To rotate.

On the other hand, the contact portion 52b of the second planetary lever 52
Abuts on the contact portion 56e of the light-shielding door drive lever 56, and the second planetary lever 52 stops at that position. Therefore, the drive planet gear 53 and the film cartridge chamber opening gear 61 do not mesh with each other, and the cartridge chamber lid 21 is
The opening is prohibited by.

While the data disk is rotating, a bar code formed on the data disk is scanned by, for example, two photo reflectors provided opposite to the data disk.
The bar code on the data disk indicates various information related to the film cartridge 1, and such information can be read by scanning the bar code. Further, the stop position of the data disk of the loaded film cartridge at the time of loading is detected, so that the state of the film cartridge 1 can be determined.

If it is determined in step S15 in FIG. 7 that the reading of the information on the data disk has been completed, the process proceeds to step S17. In step S17, the position of the switching locking lever 42 is detected while the rotation of the motor M in the film rewinding direction is continued.

Since the switching locking lever 42 is urged clockwise by the urging spring 42c, the contact portion 42a of the switching locking lever 42 is constantly pressed against the cam surface 41a of the drive gear 41. . For this reason, while the data disk is rotating, the switching locking lever 42 is driven by the rotation of the drive gear 41.
Makes a rocking motion.

As described above, the stop angle of the data disk is defined for each state of photographing completed, film unexposed or development completed, but in the present embodiment, the switching locking lever 42 swings. The moving angle changes in synchronization with the angle of the data disk. That is,
When the data disk is oriented at the stop angle indicating any of the above states, the switching locking lever 42 is pushed by the cam surface 41a and rotated counterclockwise (shown in FIGS. 1 and 2). Position), the sun gear 31, the fork gear 35, the hoisting planetary gear 34 and the drive gear 4
A gear ratio of 1 is set. When the data disk is oriented in a direction other than the stop angle indicating any of the above states, the cam surface 41a is retracted from the switching locking lever 42,
The switching locking lever 42 is set at a position pivoted clockwise (a position shown in FIG. 3).

In step S17 of FIG. 7, the angle of the switching locking lever 42 is read, and if it is determined that the switching locking lever 42 is at the position shown in FIG. 3, the process proceeds to step S18.
If it is determined that it is not at the position shown in FIG. 3, step S17 is repeated. In step S18, the rotation of the motor M is stopped. With the above operation, the information on the data disk is read, and the switching locking lever 42 is stopped at the position shown in FIG.

<Film Cueing Operation> Next, in step S19 in FIG. 7, it is determined whether or not the film F has been fed to a position where the first frame of the film F faces the aperture of the camera. If it is determined that the first frame is facing, the process proceeds to step S21. If it is determined that the first frame is not facing, the process proceeds to step S20. In step S20, the motor M is rotated in the winding direction of the film F, and in step S1
Return to 9.

When the motor M is rotated in the winding direction of the film F in step S20, the sun gear 31 and the sun gear 51 rotate clockwise as shown in FIG.
The first planetary gear 32 and the second planetary gear 52 rotate clockwise.

When the switching locking lever 42 is in the position shown in FIG. 4 (the position shown in FIG. 3) in which the switching locking lever 42 is rotated clockwise, the first planetary lever 32 does not come into contact with the switching locking lever 42.
The winding planetary gear 34 that rotates in the counterclockwise direction meshes with the fork gear 35, and the fork gear 35 rotates in the clockwise direction (the winding direction of the film F). For this reason,
The film F is fed (thrusted) in the winding direction with the rotation of the cartridge fork shaft 11.

On the other hand, when the switching locking lever 42 is at the position shown in FIG. 4, the contact portion 52a of the second planetary lever 52, which is to rotate clockwise, is in contact with the contact portion 42b of the switching locking lever 42. Since the second planetary lever 52 comes into contact with the second planetary gear 52 and stops at that position, the driving planetary gear 53 does not mesh with the one-turn gear 55.

In step S19 of FIG.
Is detected, the rotation of the motor M is stopped in step S21 to stop the film feeding. Thus, the cueing of the film F is completed.

In step S22 in FIG. 7, an operation for photographing is performed. In a succeeding step S23, it is determined whether or not the shooting has been completed up to the last frame of the film F. If it is determined that the shooting has been completed, the process proceeds to step S31 in FIG. It returns to S22. In the shooting operation, the motor M
The film F can be fed (rewound) by rotating the film F in the winding direction.

<Film Rewind Operation> After the photographing of the film F is completed, the motor M is rotated in the film F rewind direction in step S31 of FIG. In step S32, it is determined whether or not rewinding of the film F has been completed. If it is determined that rewinding has been completed, the process proceeds to step S33. If it is determined that rewinding has not been completed, the process returns to step S31.

When the motor M is rotated in the rewinding direction of the film F in step S31 as described above, the sun gear 31 and the sun gear 51 rotate counterclockwise as shown in FIG. And the second planetary lever 52 rotates counterclockwise.

As shown in FIG. 5, the light shielding door drive lever 56
Is in a position rotated in the counterclockwise direction, the first planetary lever 32 rotates without abutting on the locking portion 56d of the light shielding door drive lever 56, and the rewind planetary gear 33 and the fork gear 35 The rewind gear 34 meshes with the drive gear 41, respectively.

When the second planetary lever 52 rotates, the contact portion 52b of the second planetary lever 52 comes into contact with the contact portion 56e of the light door drive lever 56, so that the second planetary lever 52 stops at that position. The drive planet gear 53 and the film cartridge chamber opening gear 61 do not mesh with each other. Therefore, the opening of the cartridge chamber lid 21 remains prohibited.

While the motor M is rotating, the fork gear 35
Is rotated in the direction of rewinding the film F, thereby performing the rewinding operation of the film F and rotating the data disk. During this time, the switching locking lever 42 pressed against the gear surface 41a of the drive gear 41 repeatedly swings.

In step S32 of FIG.
When the completion of rewinding is detected, the process proceeds to step S33. In step S33, the direction of the rotating data disk is determined, and if it is determined that the data disk is at a predetermined stop angle, that is, at a predetermined angle indicating the completion of shooting, step S34.
Then, if it is determined that the angle is not at the predetermined angle, the process returns to step S31. In step S34, the rotation of the motor M is stopped. The rewinding operation of the film F is performed by the above operation, and the data disk is stopped at a predetermined stop angle. At this time, the switching locking lever 42 stops at the position shown in FIG. 5, that is, at the position shown in FIG.

In a succeeding step S35, it is determined whether or not the eject button has been operated. If it is determined that the eject button has been operated, the process proceeds to step S1 in FIG. 6, and the above operation is repeated. If it is determined in step S35 that the eject button has not been operated, the process proceeds to step S36. In step S36, it is determined whether a predetermined time has elapsed. If it is determined that the predetermined time has elapsed, the sequence ends.
If it is determined that the time has not elapsed, the process returns to step S35.

As described above, the operations from the removal of the photographed film cartridge 1 to the end of photographing of the new film cartridge 1 are performed by the sequence of <light-shielding door closing operation> to <film rewinding operation>. Will be
