DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera using a photographic film such as a so-called silver halide film, and more particularly to a shutter and a drive mechanism for a photographic film.

[0002]

2. Description of the Related Art In a camera using a photographic film such as a silver halide film, it is necessary to perform operations such as opening and closing a shutter and feeding a film. Conventionally, in cameras provided relatively inexpensively, such as a single-focus camera equipped with a single-focus lens, the motor is usually used to feed the film electronically. In many cases, a manual drive system using a mechanical operation mechanism that utilizes the operation force of the photographer was adopted for the operation of. In the manual drive system, reliable and accurate operation of the shutter is important, and if necessary, the feeling of release in operation has to be sacrificed. In such a case, an appropriate operation feeling in the release operation cannot be obtained. Furthermore, in the manual drive system, when a self-timer function is desired to be realized, a complicated governor mechanism must be used to obtain an operation time of a timer for delaying a release operation. In addition, in order to completely electronically drive the shutter, it is necessary to provide a new motor or a driving source dedicated to the shutter, such as a plunger, separately from the film feeding.

An example of a conventional shutter mechanism using a manual drive system with a mechanical operating mechanism is disclosed in Japanese Patent Application Laid-Open No. 9-4 / 1997.
No. 3675. JP-A-9-4367
Japanese Patent Application Laid-Open No. 5 (1999) -1995 discloses a shutter blade rotatably supported by a camera body to open and close an exposure opening, and a kick type in which the shutter blade is rotated in an opening direction by colliding with a claw portion of the shutter blade. A shutter mechanism including a lever is disclosed. The shutter mechanism includes a support member provided on the camera body and extending in a substantially horizontal direction, and a support member having one end supported on an upper surface of the support member and a locking claw at the other end protruding forward from a front edge of the support member. A locking member is provided for moving the locking claw up and down, and a lever member is supported on the lower surface of the support member at one end so as to be rotatable in the horizontal direction and moves the lever at the front end in the vertical and horizontal directions. The lever includes a kicking member and a rigid member that hang down from a front end of the lever member, and a gap for elastically deforming the kicking member toward the rigid member is provided between the kicking member and the rigid member. I have.

In this case, when the shutter button of the camera is pressed, the lever member previously locked by the locking claw descends over the locking claw while descending, and then moves to the claw portion of the shutter blade. The claw portion is horizontally moved toward and pressed by the kicking member in the shutter opening direction,
The return path after the shutter is opened is a horizontal straight path.In the return path, the kicking member elastically deforms and goes over the claw portion. Return. Such a shutter mechanism of the camera eliminates disadvantages such as complicating the operation mechanism of the lever for opening the shutter blade by kicking the shutter blade, increasing the cost by increasing the number of parts, and requiring a large operation space.

Opens and closes an aperture 17 that forms a photographing optical path. The lever 13 is pivotally supported at a substantially central portion, and is urged to rotate clockwise in the drawing to lock the slide lever 14. The lever 13 is engaged with a pin 6 a protruding from the gear 6.
a to rotate the slide lever 1
Release the lock of 4. The slide lever 14 is provided so as to be able to move forward and backward substantially in the left and right directions in the figure, and is urged to the left in the figure. The shutter blade 15 is pivotally supported at a portion deviating from a portion that opens and closes the aperture 17 and is urged clockwise in the drawing. The stopper 16 locks the shutter blade 15 at a predetermined position against the clockwise turning force.

That is, when the lock by the lever 13 is released in the shutter charge state, the slide lever 14 moves to the left in the figure, and rotates the shutter blade 15 counterclockwise as shown in FIG. , Shutter blade 15
Is retracted from the aperture 17 and the shutter is opened. When the slide lever 14 further moves to the left in the figure, the engagement with the shutter blade 15 is released, and the shutter blade 15
Rotates clockwise, is locked by the stopper 16, and stands still with the aperture 17 closed. When the shutter is charged, the slide lever 14 moves rightward in the figure and is locked by the lever 13 as shown in FIG.

Next, the operation of the above-described camera driving mechanism will be described. First, regarding the operation of the entire drive mechanism, FIGS.
This will be described with reference to FIG. First, when a photographic film is loaded into the camera, the state shown in FIG. 1 is obtained. When the motor 1 rotates in the direction A shown in FIG.
Rotates around the planetary gear 4A in the counterclockwise direction in the figure,
The planet gear 4B is connected to the gear 9. Therefore, the motor 1
And gears 12 are gears 2, 3, 4A (planetary gears), 4B
(Planetary gears), 9, 10 and 11, and the first frame set, that is, the photographic film is pulled out of the patrone by the rotation of the motor 1 and the 1
A frame is set. At this time, the shutter is charged. After that, when the release operation is started by the release operation, the motor 1 is rotated in the reverse direction, and the planetary gear 4B rotates around the planetary gear 4A in the illustrated clockwise direction by the rotation of the motor 1 in the illustrated B direction, that is, clockwise. By rotating, the planetary gear 4B is connected to the gear 5 as shown in FIG. Therefore, the motor 1 and the gear 6 are combined with the gears 2, 3,.
They are connected via 4A (planetary gear), 4B (planetary gear) and 5, and the shutter is driven to open and close. After the shutter opening / closing operation, the motor 1 is again rotated in the counterclockwise direction A,
The motor 1 and the gear 12 are connected, and the photographic film is fed by one frame in a direction to be taken out of the cartridge. This shutter opening / closing operation and one frame feed constitute a continuous shooting sequence,
Repeat each time one frame is shot.

The photographic film is fed gradually one frame at a time.
When the photographing of all the frames of the photographic film is completed and the end of the film is detected, the planetary gear 7A is rotated manually around the planetary gear 7B in the counterclockwise direction in the figure by a manual operation, so that the operation trajectory of the planetary gear 4B is moved. 3 and set in the state shown in FIG. 3, and thereafter, the motor 1 is rotated in the counterclockwise direction A in the figure. Thereby, the motor 1 and the gear 8 are connected via the gears 2, 3, 4A (planetary gear), 4B (planetary gear), 7A (planetary gear) and 7B (planetary gear). The photographic film is rewound into the patrone. Also, when the user wants to rewind the photographic film from the middle before completing the shooting of all the frames of the photographic film, set the planetary gear 7A to the state shown in FIG. 3 by manual operation and rotate the motor in the counterclockwise direction A. By doing so, the motor 1 and the gear 8 are connected to rewind the photographic film.

Next, the operation of the shutter drive mechanism will be described with reference to FIGS. First, in the initial stage of the shutter sequence, the slide lever 14 urged to the left in the drawing is charged by a shutter charging operation associated with the first frame setting as shown in FIG.
It is arranged rightward in the figure against the biasing force to the left in the figure. The lever 13 is biased to rotate clockwise. The shutter blade 15 is urged in a clockwise direction, that is, in a shutter closing direction, and is locked by a stopper 16 to close the aperture 17. Slide lever 1
4 is locked by the lever 13 in the state shown in FIG. When the motor 1 rotates clockwise B in the drawing by the shutter driving operation in the state of FIG. 2, the gear 6 rotates in the direction C shown in FIG. Rotate. The rotation of the lever 13 releases the lock of the slide lever 14, and the slide lever 14 slides to the left in the drawing. This slide lever 14
The shutter blade 15 rotates counterclockwise due to the movement of. After the state of FIG. 5 is reached, the shutter blade 15 returns to the closed state by the urging force of a spring or the like. The charge of the shutter is set by moving the slide lever 14 to the right using a sprocket that rotates using the movement of the photographic film from the patrone. At this time, the lever 13 rotates clockwise to return the gear 6 to the state shown in FIG. 4 and lock the slide lever 14.

As described above, the motor 1 used for feeding the film not only winds up the photographic film by one frame but also drives the shutter and rewinds. Specifically, by rotating the motor 1 in the illustrated counterclockwise direction B, the motor 1 and the shutter mechanism are connected, and the shutter is opened and closed to perform photographing. Then, by the reverse rotation of the motor 1, that is, the rotation in the clockwise direction A in the drawing, the motor 1 and the film feeding mechanism for extracting and transporting the photographic film from the patrone are connected to feed the photographic film one frame at a time. When the photographing of the photographic film is completed, a rewinding mechanism for returning the photographic film to the patrone by rotating either the counterclockwise direction A or the clockwise direction B by a switching operation is connected to the motor 1 by a switching operation. Then, the photographic film is rewound into the patrone. In this manner, the film feeding / rewinding and the driving of the electronic shutter can be performed by only one motor, so that the cost can be reduced and the operation feeling of the release due to the electronicization of the shutter can be improved. Space is also achieved. (Claim 1
Further, the film feed motor 1 performs all of the winding, shutter drive, and rewind of the photographic film by one frame. Specifically, at first, the film feeding mechanism is not connected to the motor 1 but is separated from the motor 1. When the photographic film is loaded, the motor 1 is connected to the film feeding mechanism by the rotation of the motor 1 in the counterclockwise direction A to set the first frame of the photographic film. When the photographer performs a release operation, the motor 1 and the shutter driving mechanism are connected using the clockwise rotation of the motor 1 to operate the shutter. Then, by utilizing the rotation of the motor in the counterclockwise direction A, the shutter drive mechanism and the motor 1 are disconnected from each other, the motor 1 is connected to the film feeding mechanism, and the photographic film is fed one frame at a time.

These operations are repeated for each release operation during photographing. When the photographing of one photographic film is completed, the motor 1 and the rewinding mechanism are connected by a manual operation at a position where the connection between the motor and the shutter driving mechanism is interrupted or at a position where the connection between the motor and the shutter feeding mechanism is interrupted. A rewind operation is performed. As for the operation of the shutter, the shutter blade 15 is urged to the closing side, and the motor 1 operates the mechanism that opens and closes the shutter blade 15 after opening it for a predetermined time. In this way, although manual switching is required at the time of rewinding, film feeding and electronic shutter driving can be performed by only a single motor 1, thereby reducing cost and cost.
Electronic shutter and space saving can be achieved.

The gear 9, the gear 11, and the gear 12 are a film feeding system that constitutes a film feeding unit that conveys the photographic film in a direction to be pulled out from the cartridge. Although the motor 1 and the gear 12 are shown coaxially, they are not directly connected. The planetary gears 4A and 4B constitute drive path switching means for selectively transmitting the driving force of the motor 1 to the gear 5, the planetary gear 7A and the gear 9 according to the rotation direction.

Similarly, when the motor 1 rotates in the second direction, for example, the clockwise direction B in FIG. 6, while the planetary gear 7A is retracted from the operation trajectory of the planetary gear 4B, the planetary gear 4A The planetary gear 4 </ b> B is connected to the gear 5.

When the lever 21 is rotated counterclockwise in the figure based on the stop of the gear 12 when the end of the film is detected, the locking lever 24 is rotated counterclockwise in the figure. Release the lock (see FIG. 8). When the release of the locking lever 24 is detected by the sensor portion 21a of the lever 21, the motor 1 is rotated in the illustrated clockwise direction B by a predetermined amount (see FIG. 9), and the lever 23 is rotated in the counterclockwise direction. Planetary gear 7A to planetary gear 4B
(See FIG. 10), and the gear 8 of the rewinding system is connected to the planetary gear 4B.

Next, the operation of the camera driving mechanism according to the third embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows an initial state. In the state shown in FIG. 6, the lever 23 is urged to rotate in the counterclockwise direction in the figure, but this lever 23 is locked by the locking lever 24, and its rotation is prevented. When a photographic film is set in this state, the motor 1 rotates in the counterclockwise direction A in the drawing to reach the state shown in FIG. 7, the rotation of the motor 1 is controlled by the gear 2, the planetary gears 3A and 3A.
B, and transmitted to the gear 9 via the planetary gears 4A and 4B, and further transmitted to the gear 12 via the gear 11. Therefore, the motor 1 drives the gear 12 to set the first frame.

Thereafter, the motor 1 is rotated clockwise B to return to the state shown in FIG. 6, and the motor 1 drives the gear 5 via the gear 2, the planetary gears 3A and 3B, and the planetary gears 4A and 4B. I do. The gear 6 is rotated by the rotation of the gear 5 by the motor 1, and the shutter is opened and closed. After the shutter is actuated, the motor 1 rotates again in the counterclockwise direction A in the drawing to reach the state shown in FIG. 7, and feeds the photographic film by one frame. During the shooting operation, the shutter operation and the one-frame feeding operation are repeated. At the end of the photographic film, when the photographic film reaches the end, the gear 12 that winds up the photographic film stops rotating, and the lever 21 rotates counterclockwise in the drawing by the action of the planetary gears 3A and 3B. As a result, as shown in FIG. 8, the locking lever 24 is rotated counterclockwise in the figure to release the locking of the lever 23 by the locking lever 24. At this time, when the release of the locking lever 24 is detected based on the position of the sensor portion 21a of the lever 21, for example, the motor 1 is rotated in the illustrated clockwise direction B by a predetermined slight amount as shown in FIG. When the lever 23 released from the locking by the locking lever 24 rotates counterclockwise in the figure and the planetary gear 7A meshes with the planetary gear 4B as shown in FIG. 10, the motor 1 is shown. By rotating in the counterclockwise direction A, the gear 8 is rotated via the planetary gears 7A and 7B to rewind the photographic film.

As described above, in the camera driving mechanism according to the third embodiment, the photographic film is wound up by one frame by the motor 1 used for feeding, shutter operation, and rewinding. Specifically, initially, the rewinding system such as the gear 8 is not connected to the motor 1 and is separated from the operation trajectories of the planetary gears 4A and 4B. When the photographic film is set, the motor 1 is connected to a film feeding system for feeding one frame by rotating in the direction A in the drawing to execute the first frame setting of the photographic film. When the release operation is performed, the motor 1 and the shutter drive system such as the gear 6 are connected by the reverse rotation of the motor 1, that is, the rotation in the direction B in the drawing, to open and close the shutter. Thereafter, the connection between the shutter drive system and the motor 1 is disconnected by the rotation of the motor 1 in the direction A, the motor 1 is connected to the film feeding system for feeding one frame, and the photographic film is fed by one frame. The shutter operation and the one-frame feeding operation are repeated during shooting. Meanwhile, the film feeding system is held at a position where the motor 1 and the film feeding system can be connected by mechanisms such as the lever 23 and the locking lever 24. In this state, the rewinding system is connected to the motor 1. Can not do it.

At the end of photographing, the lever 21 is actuated by using the force (tensile tension) of the photographic film to pull out of the patrone at the end portion, and the locking lever 2 is operated.
4 to release the locking of the lever 23. Thereby,
The rewinding system enters a position where it can be connected to the motor 1, making it impossible to connect the film feeding system to the motor 1. Thus, by rotating the motor 1 in the direction A, the motor 1 and the rewinding system are connected, and an automatic rewinding operation can be achieved without manual switching operation. As for the shutter operation, similarly to FIGS. 4 and 5, the shutter blade is initially urged to close, and in response to the release operation, the shutter blade is once opened and then closed at a predetermined exposure time. A mechanism for sequentially executing a series of operations is operated by the motor 1.

In this manner, all operations of film feeding, shutter operation, and rewinding can be achieved by a single motor 1, so that the operation feeling of the release is improved, the cost is reduced, and the space is saved. can do. Moreover, the mechanism is slightly more complicated than in the first embodiment,
Detecting means capable of generating an electronic signal is required, which slightly increases the cost, but eliminates the need for manual operation during rewinding. (Fourth Embodiment) A fourth embodiment of the present invention is an embodiment in which the present invention is applied to a camera of a type that performs preliminary winding, in which a photographic film is entirely wound from a patrone to a take-up spool. And rewind one frame at a time while shooting sequentially. In this case, the drive mechanism shown in FIGS. 6 to 10 is used as in the third embodiment described above. In the fourth embodiment, FIG.
FIG. 7 is a view showing a state of the drive mechanism before loading the photographic film and at the time of the release operation, FIG. 7 is a view showing a state of the drive mechanism at the time of loading the photographic film and at the time of preliminary winding, and FIG. FIG. 9 is a diagram showing a state of the driving mechanism, and FIG.
Is a diagram showing a state in which the drive mechanism rewinds the film one frame at a time.

6 to 10, the gear 2 and the planetary gears 3A and 3B transmit the driving force of the motor 1 to the planetary gear 4A. The gear 5 and the gear 6 are shutter driving systems that constitute shutter driving means. In addition, this fourth
In the case of the embodiment, the planetary gears 7A and 7B and the gear 8 are a rewinding system which constitutes a rewinding means for sequentially rewinding the photographic film drawn from the patrone and wound on the take-up spool one by one. The gear 9, the gear 11, and the gear 12 are a pre-winding feed system that constitutes a pre-winding feeding unit that pulls out the photographic film from the cartridge and performs pre-winding. Motor 1 and gear 12
Are shown coaxially but not directly connected.

The planetary gears 4A and 4B constitute drive path switching means for selectively transmitting the driving force of the motor 1 to the gear 5, the planetary gears 7A and the gear 9 according to the direction of rotation. The planetary gears 7 </ b> A and 7 </ b> B constitute a coupling operation means, and operate in association with the lever 21, the coupling member 22, the lever 23, the locking lever 24, and the spring 25. The rotation of the planetary gears 4A and 4B in a state where the lever 23 is locked by the locking lever 24 and the planetary gear 7B is retracted from the operation trajectory of the planetary gear 4B causes the gear 9, the gear 11, and the gear of the preliminary winding system to rotate. 12 is retracted / coupled to the planetary gear 4B of the drive path switching means. That is,
When the motor 1 rotates in a first direction, for example, a counterclockwise direction A in the figure, the planetary gear 4A rotates counterclockwise, and FIG.
8, and the planetary gear 4B is connected to the gear 9 as shown in FIG.
Similarly, when the motor 1 rotates in the second direction, for example, the clockwise direction B in FIG.
And 4B rotate clockwise, and the planet gear 4B is connected to the gear 5.

When the lever 21 is rotated counterclockwise in the figure based on the stop of the gear 12 when the end of the film is detected, the locking lever 24 is rotated counterclockwise in the figure. Release the lock (see FIG. 8). When the release of the locking lever 24 is detected by the sensor portion 21a of the lever 21, the motor 1 is rotated in the illustrated clockwise direction B by a predetermined amount (see FIG. 9), and the lever 23 is rotated in the counterclockwise direction. Planetary gear 7A to planetary gear 4B
(See FIG. 10), and the gear 8 of the rewinding system is connected to the planetary gear 4B.

Next, the operation of the camera driving mechanism according to the fourth embodiment of the present invention will be described with reference to FIGS. FIG. 6 shows an initial state. In the state shown in FIG. 6, the lever 23 is urged to rotate in the counterclockwise direction in the figure, but this lever 23 is locked by the locking lever 24, and its rotation is prevented. When a photographic film is set in this state, the motor 1 rotates in the counterclockwise direction A in the drawing to reach the state shown in FIG. 7, the rotation of the motor 1 is controlled by the gear 2, the planetary gears 3A and 3A.
B, and transmitted to the gear 9 via the planetary gears 4A and 4A, and further transmitted to the gear 12 via the gear 11. Therefore, the motor 1 drives the gear 12 to wind the photographic film from the patrone to the end to perform the preliminary winding.

When the photographic film reaches the end, the gear 12 winding the photographic film stops rotating, and the action of the planetary gears 3A and 3B causes the lever 21 to rotate.
Is rotated counterclockwise in the figure, whereby the locking lever 24 is rotated counterclockwise in the figure, as shown in FIG. 8, and the locking of the lever 23 by the locking lever 24 is released. At this time, when the release of the locking lever 24 is detected based on the position of the sensor portion 21a of the lever 21, for example, the motor 1 is rotated in the illustrated clockwise direction B by a predetermined slight amount as shown in FIG. When the lever 23 released from the locking by the locking lever 24 rotates counterclockwise in the figure and the planetary gear 7A meshes with the planetary gear 4B as shown in FIG. 10, the motor 1 is shown. By rotating in the counterclockwise direction A, the gear 8 is rotated via the planetary gears 7A and 7B to set the first frame of the photographic film.

Thereafter, the motor 1 is rotated clockwise B to return to the state shown in FIG. 6, and the motor 1 drives the gear 5 via the gear 2, the planetary gears 3A and 3B, and the planetary gears 4B and 4A. I do. The gear 6 is rotated by the rotation of the gear 5 by the motor 1, and the shutter is opened and closed. After the shutter is operated, the motor 1 rotates again in the counterclockwise direction A in the drawing to reach the state shown in FIG. 10, and feeds (rewinds) the photographic film by one frame. During the shooting operation, the shutter operation and the one-frame feeding operation are repeated. Then, at the end of the photographic film, the photographic film is wound into the cartridge in the state shown in FIG.

As described above, in the camera driving mechanism according to the fourth embodiment, the motor 1 performs preliminary winding of the photographic film, shutter operation, and rewinding one frame at a time. Specifically, initially, the rewinding system such as the gear 8 is not connected to the motor 1 and the planetary gears 4A and 4B
It is also separated from the orbit. Then, when the photographic film is set, the motor 1 is connected to a pre-winding feed system for pre-winding the photographic film by rotation in the direction A in the drawing to execute the pre-winding of the photographic film. In the meantime, the mechanism such as the lever 23 and the locking lever 24 holds the pre-winding feed system at a position where the motor 1 and the pre-winding feed system can be connected.
The frame-by-frame rewinding system cannot be connected to the motor 1. At the end of the pre-winding, the lever 21 is operated by using the force for the photographic film to pull out of the patrone at the end portion, and the lever 23 is operated by the locking lever 24.
Release the lock. As a result, the rewinding system for each frame enters a position where it can be connected to the motor 1, and the connection with the motor 1 of the pre-winding feeding system becomes impossible. Therefore, by rotating the motor 1 in the direction A, the motor 1 and the rewinding system are connected, and a first frame set by an automatic rewinding operation can be achieved without a manual switching operation.

When the release operation is performed, the motor 1
The motor 1 and the shutter drive system such as the gear 6 are connected to open and close the shutter by the reverse rotation of the shutter, that is, the rotation in the direction B in the figure. Then, the connection between the shutter drive system and the motor 1 is disconnected by the rotation of the motor 1 in the direction A, the motor 1 is connected to a rewinding system for rewinding one frame, and the photographic film is rewinded by one frame. The shutter operation and the rewinding operation for each frame are repeated during shooting. At the end of shooting, the motor 1 is connected to a rewinding system for rewinding one frame, and the photographic film is rewound to the patrone as it is. Regarding the shutter operation, as in FIGS. 4 and 5, initially,
The shutter 1 is urged to be closed, and the motor 1 operates a mechanism that sequentially executes a series of operations in which the shutter is once opened and then closed at a predetermined exposure time in response to a release operation.

In this manner, the single operation of the motor 1 can achieve all the operations of pre-winding the photographic film, shutter operation, and rewinding one frame at a time. Thus, cost reduction and space saving can be achieved. In addition, as compared with the second embodiment, the mechanism is slightly complicated, and a detection means capable of generating an electronic signal is required, and the cost is slightly increased. However, the manual operation at the end of the preliminary winding is unnecessary. Become.
According to the first to fourth embodiments, the film feeding / rewinding and the electronic shutter can be achieved by a single motor. Drive control becomes possible, and with a simple configuration, at least one of the functions of an electronic self-timer and a remote control operation can be added, and both of them can be supported at low cost. (Corresponding to claim 6) Also, as shown in the above-described first to fourth embodiments,
The drive path switching means for selectively switching the motor 1 and the gear 5 of the shutter drive system, the planetary gear 7A of the film feed system or the rewind system, and the gear 9 of the rewind system or the pre-winding feed system to switch and transmit. And the planetary gear 4A that rotates in a required direction by the forward and reverse rotations of the motor 1 and the planetary gear 4B that revolves. (Corresponding to claim 7) In the first to fourth embodiments described above, the operation timing of the shutter by the shutter drive system including the gear 5 is
