The exposure state of the film cartridge 10 can be visually detected by positioning the rotary display plate 12b formed at one end of the cartridge spool 12 opposite to the bearing hole 12a below the predetermined display hole 16a.

In such a camera that enables the use of the film cartridge 10, when the feeding of the film F is performed without providing a drive motor or a control circuit, various operations relating to photographing are performed using the feeding operation of the film F. Is performed.
For example, operations such as shutter charging and rotation locking (spool parking) of the cartridge spool 12 after rewinding, which have been conventionally performed by a control circuit and motor drive, must be performed using manual film feeding.

For each mechanism of this type of camera, the feeding direction of the film F is an important operation requirement, and therefore the feeding direction of the film F must not be reversed during photographing. In other words, it is necessary not to operate the film driving means in the rewind direction during the film feeding. If a control circuit and a motor are not provided, the number of operations required by the photographer may increase and the operation may become complicated. Therefore, a camera that can perform photographing with as simple operations as possible is desired.

And A film feed dial 140, which is a driving source, has a disc-shaped operation knob 141 protruding from the camera body 21 to the outside, and is coaxially joined to a lower portion of the operation knob 141 to be connected to the camera body 21.
Drive gear 14 for transmitting rotation to internal cartridge spool drive mechanism 200 and hoist spool drive mechanism 300
The film F is fed by rotating the operation knob 141 manually in the unwinding (winding) and rewinding directions.

First, the cartridge spool drive mechanism 200 for driving the cartridge spool drive shaft 131 will be described. First gear 201 meshing with driving gear 142
Is supported by a gear arm 204 rotatably supported by a shaft 142x of a driving gear 142 so as to be able to rotate around the shaft 201x and revolve around the shaft 142x. A planetary gear 203 coaxial with the first gear 201 is provided via a gear shaft 202 extending in the direction of the rotation axis 201x of the first gear 201. With the revolution of the first gear 201 with respect to the driving gear 142, the planetary gear 203

A cartridge spool driving shaft 131 is provided on the side of the film cartridge chamber 23 of the cartridge spool driving gear 205.
And the axis is fixed. The cartridge spool drive shaft 131 has a substantially cylindrical base 133, and a coupling portion 135 having a smaller diameter than the base 133, which is formed integrally with one end of the base 133 so that its axis is aligned. The coupling portion 135 is engaged with the spool drive bearing hole 12a of the cartridge spool 12 so as to be insertable and detachable, and the distal end portion has a smaller diameter toward the distal end, and a top surface is formed at the distal end. The coupling portion 135 has a key portion 137 protruding from the outer peripheral surface. When the film cartridge 10 is loaded in the film cartridge chamber 23, the coupling portion 135 is fitted into the spool drive bearing hole 12a of the cartridge spool 12, and Further, the key portion 137 has the key groove 14.
Is engaged with the cartridge spool drive shaft 131.
Is transmitted to the cartridge spool 12.

Next, the winding spool drive mechanism 300 will be described. The first gear 301 is located at a position different from the first gear 201 on the outer periphery of the driving gear 142.
The first gear 301 and a second gear 303 below the camera body 21 are connected to a gear shaft 30 extending vertically in the vicinity of the film cartridge chamber 23.
2 are coaxially connected to the upper and lower ends. A large-diameter gear 305 and a large-diameter gear 307 are sequentially meshed with the second gear 303,
A planet gear 309 is supported by the gear arm 308, which is rotatable by a predetermined width with respect to the shaft 307x of the large diameter gear 307, so as to revolve with respect to the large diameter gear 307. Axis 30
The planetary gear 309 having 9x has a second planetary gear 311
Are coaxially connected. The planetary gear 309 and the second planetary gear 311 are in a range where the rotation of the gear arm 308 is allowed when the rotation direction of the film feed dial 140 is changed from the feeding (winding) direction to the rewinding direction or vice versa.

The gear 311 meshes.

The film feeding mechanism of the camera 20 operates as follows. When the film feed dial 140 is rotated in the feeding direction (counterclockwise in FIG. 5) in a state where the film cartridge 10 is mounted in the film cartridge chamber 23, the cartridge spool driving shaft 131 is fed through the cartridge spool driving mechanism 200. Cartridge spool 12 (spool drive bearing hole 12a) that rotates in the direction (same clockwise) and engages with coupling portion 135.
Of the film cartridge 10 by the rotation of
The film F passes through the film feeding space 29 in the camera body 21 and advances toward the winding spool 25 (initial feeding of the film F). At this time, the hoisting spool 25 moves in the hoisting direction (FIG.
When the leading end of the film F is wound around the winding spool 25, the film F is pulled on the winding spool 25 by the winding speed of the winding spool 25 which is slightly higher than the feeding speed of the cartridge spool 12. And wound up by a predetermined amount. The reason why the rotation on the winding side is made faster than on the feeding side is to prevent the film F from becoming loose, and the cartridge spool driving mechanism 2
00 and the gear ratio setting of the hoisting spool drive mechanism 300, the cartridge spool 12 rotating by a common drive source
And the rotation speed of the winding spool 25 can be changed. Even if the second planetary gear 311 and the hoisting spool drive gear 313 are separated at the beginning of winding, the planetary gear 309 and the second planetary gear 311 are rotated by the rotation of the film feed dial 140 in the feeding (winding) direction. In order to revolve in the direction of the hoisting spool drive gear 313 and mesh therewith, the hoisting spool 25 starts rotating in the hoisting direction.

On the other hand, when rewinding the film F, the film feed dial 140 is rotated in the rewinding direction (clockwise in FIG. 6). Since the rotation direction of the large-diameter gear 307 changes, the planetary gear 309 and the second planetary gear 311 revolve counterclockwise as shown in FIG.
1 is disengaged from the hoisting spool drive gear 313, and they are separated from each other. Since power is not transmitted to the hoist spool drive gear 313, the hoist spool 25 is free and the film F is rewound by the cartridge spool 12
Is performed only by rotation in the rewind direction. Accordingly, the cartridge spool 12 of the film cartridge 10 is a spool for feeding and rewinding, and
Reference numeral 5 denotes a spool exclusively used for winding.

Is rotatably supported about a bearing hole 81a by a rotating shaft 123 disposed therein. Here, the rotation transmitting teeth 7
Since the film number plate 80 is installed so that the gear 4 engages with the gear 83, when the film F is fed in the forward and reverse directions, the sprocket 70 engaged with the perforation P rotates in the forward and reverse directions. The film number plate 80 also rotates.
Perforation P: One set (two) per shot
Since the sprocket 70 is formed of a film and has four engaging teeth 72, when the film F is fed (sent or rewound) by one frame, the sprocket 70 makes a half turn. As described above, the rotation transmitting teeth 74
Is provided with two concave portions 75, so that half rotation of the sprocket 70 is performed by the concave portions 75 of the rotation transmitting teeth 74.
The rotation corresponds to one minute. Accordingly, for feeding one frame of the film F, the film plate 80 rotates by one tooth of the gear 83 meshing with the concave portion 75 of the rotation transmitting tooth 74. When the number of photographed images is “0”, the film number plate 80
The rotation phase is set so that the communication portion 87 of the rotation restricting rib 85 faces the rear side of the camera 20 (initial position). At the same time, the second engaging portion 59 of the spool parking lever 50 comes into contact with a predetermined position near the rotation restricting rib 85 from the bottom side of the camera 20 when the film number plate 80 is installed.

A one-way clutch 120 is provided above the rewind lever 60. The one-way clutch 120 includes a substantially straight plate-shaped bar 121, a ring portion 122 at one end of the bar 121, and a driving gear regulating portion 12 at the other end.
7 and a stopper release projection 129, and a clutch stopper 123 at an intermediate portion. The clutch stopper 123 is provided on the lower side surface of the bar 121 with respect to the driving gear restricting portion 127 extending on the upper surface side of the bar 121. The clutch stopper 123 has a clutch inclined surface 124 inclined to the rear side of the camera 20, and a stopper concave portion 125 having a bottom surface substantially parallel to the longitudinal direction of the bar 121. A stopper release protrusion 129 extends from the clutch stopper 123 in the direction in which the bar 121 extends.

The one-way clutch 120 is installed so that the clutch stopper 123 can be turned around the ring 122 with the clutch stopper 123 facing the front of the camera 20. Bar 121
Is substantially parallel to the sliding direction of the rewind lever 60, the driving gear restricting portion 127 engages with the driving gear 142 to stop its clockwise rotation. The one-way clutch 120 is urged toward the locking position (counterclockwise) as a whole by a tension spring 119. For the one-way clutch 120, the rewind lever 60
Is located in the vicinity of the clutch stopper 123. When the door driver drive lever 40 is rotated to the position shown in FIG.
It is possible for the user 9 to push up the stopper release projection 129 toward the back of the camera 20. The one-way clutch 120, the rewind lever 60, the door driver driving lever 40, and the driving gear 142 constitute a one-way clutch mechanism that restricts the operation of the film feeding mechanism in the feeding direction only when the film F is sent.

The operation of the cartridge lid lock mechanism and the one-way clutch mechanism having the above-described configuration is described with reference to the camera 2.
11 will be described with reference to FIGS. 11 to 13 show the interlocking relationship between the locking operation of the cartridge lid 27 and the cartridge spool 12, that is, the operation of the cartridge lid locking mechanism. 11 shows a state in which the film F has been sent out from the film cartridge 10, FIG. 12 shows a state in which the rewinding of the film F has been completed,
FIG. 13 shows a state in which the spool parking is completed from the state of FIG. 12 and the lock is released, respectively.
14 to 16 show the interlocking relationship of the one-way clutch mechanism. FIG. 14 shows a state in which the film F is fed (winded up), FIG. 15 shows a state in which the film F is rewound, and FIG. 16 shows a state in which spool parking is completed and the cartridge lid is unlocked.

When the film F shown in FIG. 14 is sent out, the driving gear restricting portion 127 of the one-way clutch 120
Are engaged with the driving gear 142. Since the one-way clutch 120 is restricted by the lever rotation restricting protrusion 65 of the rewind lever 60, the one-way clutch 120 does not rotate counterclockwise (biasing direction) from the position in FIG. Therefore, the driving gear 142
Cannot be rotated clockwise (rewind direction). On the other hand, since rotation of the one-way clutch 120 in the clockwise direction is permitted, it is possible to rotate the driving gear 142 in the counterclockwise direction (delivery direction). At this time, each time the driving gear 142 rotates, the driving gear regulating unit 1
Although 27 moves over each tooth of the driving gear 142, the one-way clutch 120 always returns to the illustrated state by the urging force of the tension spring 119. Therefore, when feeding the film F, the film feed dial 140 can rotate only in the feeding (winding) direction.

FIG. 11 shows the stage of feeding the film F. During filming, when the film feed dial 140, which is allowed to rotate in only one direction, is rotated each time a frame of film is finished, the film F is sent out from the film cartridge 10 to the film feed space 29. It is wound up on a hoisting spool 25. As described above, the sprocket 70 rotates one half in response to the feeding (rewinding) of one frame of the film F, and the film plate 80 rotates by one gear 83. Therefore, when taking X frames, the film number plate 80 is rotated by X teeth. In addition,
The film F is a film cartridge 10 on the left hand side in the figure.
And is wound up by a winding spool 25 in the right-hand direction. Therefore, when the film F is fed, the sprocket 70 engaging with the perforation P rotates clockwise, and the film number plate 80 rotates counterclockwise. At the time of rewinding, reverse rotation is performed. During this time, the spool parking lever 50 is urged counterclockwise by the tension spring 111, but the second engagement portion 59 is regulated by the inner peripheral wall 86 of the rotation regulating rib 85 provided on the film number plate 80, and The lever rotation restricting projection 65 of the rewind lever 60 at the wind position is rotated by the rotation restricting surface 58.
, The spool parking lever 50 is in a state of being rotationally locked.

In the above steps shown in FIGS. 11 and 14,
The door driver 30 and the door driver drive lever 40 have the positional relationship shown in FIG. That is, the film cartridge lid 27 is closed and locked, and the light shielding door 17 is opened. In order to unlock the film cartridge lid 27 by operating the cartridge lid lock lever 151, the door driver driving lever 40 linked therewith needs to rotate counterclockwise. One side surface of the locking portion 47 is restricted by a drive lever locking surface 96 of the spool parking lever 50.
As described above, the rotation in the biasing direction of the spool parking lever 50 is locked, and as a result, the rotation of the door driver drive lever 40 in the counterclockwise direction is locked. Therefore, the unlock operation of the cartridge cover lock lever 151 cannot be performed, and the light shielding door 1 during the photographing operation is not available.
There is no danger of closing 7 and opening the film cartridge lid 27.

After photographing the predetermined number of frames X, the tension spring 1
The rewind lever 60 is slid to the rewind position against the urging force of No. 18. With this slide, the rotation restricting projection 65 is attached to the clutch inclined surface 1 of the one-way clutch 120.
While being guided by 24, it fits into the stopper recess 125. The bottom of the stopper recess 125 is slightly closer to the camera 2 than the bar 121.
0, and the rewind lever 60 is
, The one-way clutch 120 is pushed slightly clockwise. As a result, the engagement between the driving gear restricting portion 127 and the driving gear 142 is released, and the driving gear 142 can be rotated clockwise (rewinding direction). Rewind lever 60
Does not return to the wind position (biasing direction) because the lever rotation restricting protrusion 65 is fitted in the stopper concave portion 125 (FIG. 15).

When the rewind lever 60 is slid to the rewind position, the contact position of the lever rotation restricting projection 65 with respect to the spool parking lever 50 is simultaneously shifted from the rotation restricting surface 58 toward the rotation permitting recess 56. Thus, with respect to the rewind lever 60, the rotation of the spool parking lever 50 in the counterclockwise direction is released, but the inner peripheral wall 86 of the rotation restricting rib 85 still holds the second engaging portion 59. Therefore, the spool parking lever 50 does not rotate in the biasing direction. Since the door driver drive lever 40 is restricted by the drive lever locking surface 96 provided on the spool parking lever 50, the door driver drive lever 40 cannot rotate counterclockwise, and the lock of the film cartridge lid 27 cannot be released.

Subsequently, when the film feed dial 140, which is allowed to rotate clockwise, is rotated in the rewinding direction (clockwise), the cartridge is driven via the cartridge spool driving mechanism 200 including the cartridge spool driving gear 205. Spool 12 in rewind direction (counterclockwise)
And the film F is stored in the film cartridge 10. As in the case of feeding (winding up), when one frame of the film F is rewound, the film number plate 80 is moved by one gear 83 through the sprocket 70 in the opposite direction (clockwise) to the time of feeding (winding up). Rotate.
When the number of images to be photographed is X, when the reverse rotation of the gear 83X teeth is performed, the number of images to be photographed on the film number plate 80 becomes "0". The indication of the number of shots being "0" means that the communication portion 87 of the rotation restricting rib 85 has returned to the initial position facing the back side of the camera 20. In this state, since the second engaging portion 59 of the spool parking lever 50 has a phase relationship in which the inner peripheral wall 86 of the rotation restricting rib 85 is not restricted, the spool parking lever 50 is allowed to rotate counterclockwise. Therefore, when the number of films F becomes “0”, the spool parking lever 50 rotates counterclockwise around the bearing hole 51 a by the urging force of the tension spring 111.
This rotation is stopped when the first engaging portion 54 comes into contact with the gear outer peripheral surface 207 of the cartridge spool drive gear 205. At this time, since the spool parking lever 50 is at the position where the drive lever locking surface 96 regulates the rotation locking portion 47, the door driver drive lever 40 cannot be rotated counterclockwise, so that the unlock operation of the film cartridge lid 27 is performed. The state where the operation cannot be performed continues (FIG. 12).

At the stage shown in FIG. 12, the end of the first engagement portion 54 is the outer peripheral surface 2 of the cartridge spool drive gear 205.
However, since the cartridge spool drive gear 205 is rotatable, the photographer continues to rotate the film feed dial 140 in the rewinding direction. At this time, since the film F has been wound up to the film cartridge chamber 23 side and is not in the film feeding space 29, there is no engagement relationship between the perforation P of the film F and the engagement teeth 72 of the sprocket 70, and the cartridge spool drive is performed. Only the gear 205 (the cartridge spool drive shaft 131) rotates. As a result of this rotation, when the engagement concave portion 209 reaches a rotational position at which the engagement concave portion 209 can engage with the first engagement portion 54, the spool parking lever 50 further rotates counterclockwise from the above position by the urging force of the tension spring 111, First engagement part 5
4 and the engagement concave camera 209 are engaged. As a result, the rotation of the cartridge spool drive gear 205 is locked, and the cartridge spool 12 cannot be rotated by operating the film feed dial 140, and spool parking is completed. Film feed dial 140
Is stopped, the photographer can sense that the winding of the film F has been completed. At this time, the exposure state indicator 16 of the film cartridge 10 indicates that the exposure has been completed (FIG. 13).

The rotational position relationship between the key groove 14 formed on the inner wall surface of the spool drive bearing hole 12a of the cartridge spool 12 and the rotation display plate 12b of the exposure state display 16 is determined. Therefore, by regulating the stop positions of the cartridge spool drive shaft 131 and the cartridge spool drive gear 205, it is possible to arbitrarily adjust the display of the exposure state indicator 16. In this embodiment,
The engagement recess 2 of the cartridge spool drive gear 205 is set so that the spool parking is completed at a rotation phase corresponding to the display hole 16a indicating "exposed" on the rotation display plate 12b.
09, the first engagement portion 5 of the spool parking lever 50
4 is set.

When the spool parking lever 50 rotates to this position, there is no longer any restriction by the drive lever locking surface 96, so that the door driver drive lever 40 is allowed to rotate counterclockwise. That is, the cartridge lid lock lever 1
Since the operation of the lock lever 51 can be released, when the lock operation is unlocked, the rotation operation arm 43 is pushed downward (in the front direction of the camera 20) in the figure via a lock operation connection mechanism (not shown), and the door driver is driven. The lever 40 rotates counterclockwise about the center point C. As a result, the door driver driving lever 40 and the door driver 30 have the positional relationship shown in FIG. 10 as described above, and the door driver shaft 33 of the door driver 30 rotates the light shielding door operating shaft 17a to close the light shielding door 17. You. At the time of this closing, the rewinding of the film F is completed, the film F is not in the film feeding space 29, and the cartridge spool 1
Since the rotation of the cartridge spool 2 is locked, there is no possibility that the cartridge spool 12 is inadvertently rotated in the feeding direction. Thus, the film cartridge lid 27 can be opened and the film cartridge 10 can be taken out of the film cartridge chamber 23 without causing light leakage, damage to the film F or the light shielding door 17 (FIG. 13).

When the door driver drive lever 40 is rotated to the position shown in FIG. 10 by the unlock operation of the cartridge lid lock lever 151, the clutch operation projection 49 pushes the stopper release projection 129 at the tip of the rewind lever 120 to the rear side of the camera 20. , The rewind lever 1
20 is further rotated clockwise from the position shown in FIG.
Then, since the regulation of the stopper recess 125 is released, the rewind lever 60 is automatically returned to the wind position by the tension spring 118 (FIG. 16).

When the rewind lever 60 returns to the wind position, the lever rotation restricting protrusion 65 is brought into contact with the inclined surface 56b, and the rotation restricting lever 55 is moved downward in FIGS. 11 to 13 (front side of the camera 20). Move while pushing into. As a result, the spool parking lever 50 is rotated clockwise (FIGS. 11 to 13) against the biasing force of the tension spring 111, and the first engagement portion 54 and the engagement recess 209 are rotated.
Is disengaged.

To perform the next photographing operation, a new film cartridge 10 is loaded into the film cartridge chamber 23, the film cartridge cover 27 is closed, and the cartridge cover lock lever 151 is locked. The door driver drive lever 40 returns to the position shown in FIG.
The door driver 30 opens the light blocking door 17. When the door driver drive lever 40 returns, the regulation by the clutch operation projection 49 is released, and the one-way clutch 12
0 is returned to the position shown in FIG. 14 by the tension spring 119. Subsequently, the film F is sent out by operating the film feed dial 140 allowed to rotate only in the feed-out direction by the one-way clutch 120. That is, the spool parking state is released by the unlocking operation of the cartridge lid lock lever 151, and the one-way clutch mechanism is operated by the locking operation.

When the film F is sent out by a predetermined amount or more, the sprocket 70 and the film number plate 80 rotate, and
An inner peripheral wall 86 of the rotation restricting rib 85 restricts the second engaging portion 59 of the spool parking lever 50 as shown in FIG. As a result, the counterclockwise rotation of the door driver drive lever 40 is locked, so that when the film F is sent to the film feeding space 29, the film cartridge lid 2 is locked.
7 is securely held. Hereinafter, photographing is performed by repeating the above operation.

The camera 20 is further provided with a shutter charging mechanism using film feeding. FIG.
This will be described briefly with reference to FIG. The rotation direction of each member is represented by a direction as viewed from the upper surface of the camera 20. The shutter charging mechanism includes a charge lever 220 that engages with the perforation P of the film F and moves in the feeding direction of the film F, and receives a movement of the charge lever 220, and moves the camera in a direction substantially orthogonal to the movement direction of the charge lever 220. A shutter operation lever 230 that rotates around an axis provided in the vertical direction of the shutter 20 to perform a charging operation and an opening operation on the shutter blade 190, and a charge lock that restricts the rotation of the shutter operation lever 230 in a shutter charged state. It comprises a lever 240 and a charge release lever 250 that transmits a pressing operation of the release button 145 to release the regulation by the charge locking lever 240 and causes the shutter operation lever 230 to open the shutter blade 190. .

As shown in FIGS. 7 and 8, the shutter blade 19 is rotatably supported in front of the aperture 28.
0 has a kick plate 193. When the kick plate 193 is moved down to the winding spool 25, the shutter blade 190 is opened and the film F is exposed. FIG. 7 shows the shutter blade 1
90 shows a closed state, in which the shutter blade 190 is urged in the closing direction.

The charge lever 220 installed in the longitudinal direction substantially parallel to the feeding direction of the film F has two claw portions 222 facing the film F on the winding spool 25 side. A shaft 227 is provided on the side. The shaft portion 227 of the charge lever 220 is slidably and rotatably supported by a slide guide groove (not shown) formed in the film feeding direction. This allows
The claw portion 222 can be engaged with and disengaged from the perforation P of the film F, and the charge lever 220 can move together with the film F when engaged with the perforation P.

A substantially cylindrical shutter operation lever 23 supported on a rotating shaft substantially perpendicular to the feeding direction of the film F.
In the case of 0, the leg portion 233 receives the movement of the charge lever 220 and rotates counterclockwise. Shutter operation lever 2
30 has a shutter operation arm 235 protruding in the radial direction. The shutter operation arm 235 is moved toward the cartridge spool chamber 23 with respect to the kick plate 193 by the counterclockwise rotation of the shutter operation lever 230. (The position shown in FIG. 7). By operating the kick plate 193 toward the winding spool 25 from this position, the shutter blade 190 is opened. That is, the shutter is in a shutter charge state in which the shutter can be released when the shutter operation lever 230 rotates counterclockwise. Shutter operation lever 23
0 is urged in the shutter opening direction (counterclockwise). A locking groove 234 is formed in the cylindrical surface of the shutter operation lever 230 in the axial direction.

The charge locking lever 240 coaxially mounted on the film plate 80 is urged clockwise, and when the shutter operating lever 230 rotates to the shutter charging position, it rotates clockwise to rotate the first locking lever. 244 engages with the locking groove 234. At the same time, the rotation causes the second locking lever 247 to rotate and lock the driving gear 142. The rotation of the driving gear 142 in the rewinding direction is prohibited by the one-way clutch mechanism at the time of feeding (winding up) the film F, but the rotation in the feeding direction is further restricted at the time of shutter charging. As a result, the feeding of the film F becomes impossible, so that the shutter charge state is maintained.

When the release button 145 is depressed, the substantially cylindrical charge release lever 250 that rotates about the axis substantially parallel to the shutter operation lever 230 rotates counterclockwise. With this rotation, the shutter drive lever 255 projecting in the radial direction of the charge release lever 250 rotates the lock release lever 246 of the lock lever 240 counterclockwise to release the shutter charge holding. When the regulation of the charge locking lever 240 is released, the shutter operating lever 230 returns to the biased shutter opening direction (counterclockwise), so that the shutter operating arm 235 moves the kick plate 193 to the winding spool 25 side. And the shutter blade 190 is opened. When the shutter operation arm 235 passes, the shutter blade 190 is closed by the urging force. Thus, the exposure of the film F is completed.

When the above operation is completed, the above operation is repeated until the predetermined number of images have been photographed, and photographing is performed. What the photographer does with respect to photography is the film feed dial 14
It is only a rotation operation in the direction of feeding (winding up) 0 and a pressing operation of the release button. At this time, the rotation of the driving gear 142 is locked by the second locking lever 247 each time one frame is fed (winded up), so that the photographer needs to pay attention to the amount of rotation of the film feed dial 140. There is no.

After the photographing is completed, the one-way clutch 120 is released by moving the rewind lever 60 to the rewind position, as described above, and the film feed dial 140 is rotated in the rewinding direction. In the rewinding direction, since the shape of the claw portion 222 is smooth, the claw portion 222 does not engage with the perforation P and does not hinder winding.

According to the configuration of the camera 20, since the feeding direction of the film F is not inadvertently reversed, no malfunction occurs in each mechanism that operates by engaging the predetermined means with the perforation P of the film F. . Further, only when the film F is stored in the cartridge spool 10 and the cartridge spool 12 is rotationally locked, the lock of the cartridge lid 27 can be released. Therefore, light leakage and damage to the film F and the light shielding door 17 may occur. There is no. Further, the spool operation can be released and the one-way clutch mechanism can be operated by the lock operation and the release operation.

The operations performed by the photographer on the camera 20 are as follows. (1) Loading the film cartridge 10 at the time of film feeding (winding), photographing. Lock operation of the cartridge cover lock lever 151. Film feed dial 140
Rotation operation in the sending direction (for each shooting frame). Pressing the shutter release 145. (2) When shooting is completed, the rewind lever 60 is moved to the rewind position. Rotation operation of the film feed dial 140 in the rewind direction. (3) Rewinding is completed, spool parking is completed, and the lock of the cartridge cover lock lever 151 is released. Removal of the film cartridge 10. It is.

In other words, the shutter charge, the spool parking after rewinding, and the cartridge lid interlocked with the spool parking are performed by using the manual film feeding, with almost no special operation other than the normal shooting. The lock can be released and the light shielding door can be opened and closed.

Although the present invention has been described based on the illustrated embodiment, it is not limited to this. For example, the number of teeth of the sprocket and the film number plate can be made to correspond to the form of perforations provided on the film and the number of films. Further, it is possible to perform spool parking with a desired gear in the cartridge spool drive gear train other than the cartridge spool drive gear. Further, the rotation in one direction by the one-way clutch mechanism may be restricted to members other than the driving gear.
