Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a camera driving device which can be used as a film feeding device for a single-lens reflex camera.

Conventionally, various film feeding devices have been proposed for winding and rewinding a film of a camera by utilizing the power of a motor. Among them, a film feeding device using a spool drive system in which power is transmitted to the spool of the camera by a motor to wind up the film, the movement amount of the film is detected by a sprocket, and the rotation of the motor is controlled is mainstream. Is becoming.

However, in this spool drive type camera, the diameter of the spool becomes thicker as the film is wound on the spool, so that the rotation amount of the spool changes momentarily when performing one winding operation. I have to change. Therefore, with a single-lens reflex camera,
During the one-time winding operation, both the shutter and mirror charging mechanism, which is a fixed amount rotation mechanism, and the film winding mechanism, which is a non-fixed amount rotation mechanism, must be driven.

Conventionally, two motors are used for switching the driving force, one for the fixed amount rotating mechanism and the other for the non-fixed amount rotating mechanism, or one motor rotates in one direction, such as a shutter which is a fixed amount rotating mechanism. A method has been adopted in which a charge mechanism of a mirror is driven and a film winding mechanism which is an indefinite rotation mechanism is driven by rotation in the other direction.

[0005]

However, in the former prior art, since two sets of motors and their speed reducing mechanisms are required, the cost is high and it is difficult to reduce the size.

In the latter prior art, since the rotation direction of the motor has to be changed during winding, the winding speed is lowered and the winding sound is bad. Further, it is necessary to provide a detecting means for detecting the timing for switching the rotation direction of the motor, which causes an increase in cost.

The present invention has been made in view of the above-mentioned problems of the prior art, and provides a spool drive type camera drive device having a high winding speed and an excellent winding sound with a simple structure. With the goal.

[0008]

In order to solve the above-mentioned problems, the driving device for a camera according to the present invention transmits the driving force of a single motor to a film take-up spool, and the film is wound by the rotation of the spool. In a camera driving device for performing the above, a charging means for charging at least an urging member for operating either the shutter or the quick return mirror, and a first means for transmitting rotation of the motor in a first direction to the charging means. Of the transmission means, the release means other than the motor for starting the operation of the shutter or the quick return mirror by opening the biasing member charged by the charging means, and the film by the rotation of the film take-up spool. Film winding means for winding the film, and the first side of the motor Second transmission means for transmitting the rotation of the film to the film winding means, and switching from the first transmission means to the second transmission means upon completion of charging of the charging means, and the release operation of the release means. Upon completion, it is configured to include switching means for switching from the second transmission means to the first transmission means.

In this case, film rewinding means for rewinding the film by the rotation of the motor in the second direction and control means for controlling the rotation of the motor can be added.

Further, two sets of planetary gears, each of which is composed of respective sun gears, planetary gears, and arms connecting them, in which the respective sun gears mesh with each other, are connected to the two sets of arms, and a four-bar link is provided. A connecting member that forms a rotating force, an input member that inputs a rotational force of a drive source from one of the sun gears, a first output unit that outputs a rotational force from one of the two sets of planetary gears, and Second output means for outputting a rotational force from the other of the pair of planetary gears, and switching means for switching the first output means and the second output means by rotating the four-bar link of the connecting member. It can be characterized in that the rotational force from the motor is switched and transmitted in two directions.

[0011]

According to the present invention, the film can be fed by one motor, and the rotation of the motor does not change during one photographing operation. The film can be rewound by the reverse rotation of the motor.

[0012]

The present invention will be described in detail below with reference to the drawings and the like. FIG. 1 is a perspective view of an essential part showing an embodiment of a camera driving device according to the present invention, and FIG. 2 is a plan view showing a shutter charge mechanism and a mirror charge mechanism of the same embodiment. It shows the state.

The rotation of the motor 1 is transmitted to the gear 6 via the gear 2 and the reduction gears 3 to 5 provided on the rotary shaft 1a. The gears 6 and 7 and the arm 8 form a planetary gear, and 6 is a sun gear. Therefore, when the gear 6 rotates left, the rotation is transmitted to the gear 9, and when the gear 6 rotates right, the rotation is transmitted to the gear 40. A known friction mechanism is arranged between the gear 7 and the arm 8 in order to stabilize the switching of the planetary gears.

The gear 10 that meshes with the gear 9 is a gear 11,
The arm 12 constitutes a planetary gear. Gear 10
Is the sun gear. Further, the gear 13 meshing with the gear 10 constitutes a planetary gear by the gear 14 and the arm 15. Gear 13 is the sun gear. The arms 12 and 15 are connected by a lever 16, and the arms 12 and 15 and the lever 16 form a four-node link mechanism 60. A pin 22 is provided on the four-bar link. No friction mechanism is provided between the gear 11 and the arm 12 and between the gear 14 and the arm 15 as described above.

When the four-bar ring mechanism 60 is in the state shown in FIG. 1, the gear 14 and the gear 17 mesh with each other, and the rotation thereof is transmitted to the spool 19 via the gear 18 to wind the film. At this time, the gear 11 and the gear 20 described later are disengaged from each other, and the gear 11 idles.

As the film is taken up by the spool 19, the sprocket 50 having the four-toothed claw 50a engaging with the perforation of the film rotates. Then, the rotation is transmitted from the gear 51 that rotates integrally with the sprocket 50 to the gear 52. Gear 52
An electrode pattern 52a that generates a pulse signal with rotation and an electrode pattern 52b that is turned on once for one rotation of the gear 52 are provided on the upper side, and the brushes 53 and 54 are in contact with these electrodes.

In this embodiment, the speed reduction ratio of the gear 51 and the gear 52 is set so that the gear 52 rotates once by winding up one frame of film. Also, the electrode pattern 5
A sprocket switch SW1 (hereinafter referred to as a sprocket switch) composed of 2a and a brush 53 generates 16 pulses by winding one film film, and a sprocket reference switch SW2 (hereinafter referred to as a sprocket switch) composed of an electrode pattern 52b and a brush 54. It is turned on when the winding of one frame of film is completed.

When the four-node ring mechanism 60 is rotated clockwise and the gear 11 is located at the position shown by the chain double-dashed line in FIG.

In this embodiment, the gear 10 always rotates clockwise and the gear 13 rotates counterclockwise. As a result, the arm 12 tends to rotate right around the rotation axis of the gear 10, and the arm 15 tends to rotate left around the rotation axis of the gear 13. But,
Since the tips of the arms 12 and 15 are connected by a lever 16 to form a four-bar link, the arm 1
The rotational forces of 2, 15 cancel each other out.

Therefore, when the four-joint link 60 is rotated clockwise by the external force and the gear 11 and the gear 20 are engaged with each other and start rotating,
The rotation torque of itself causes the gear 11 and the gear 20 to receive a force in the direction of strengthening the meshing, and the rotation can be stably transmitted. Further, when the four-node link 60 is rotated leftward by another external force, and the gear 14 and the gear 17 are engaged and start rotating, similarly, the rotation torque of itself also causes the gear 14 and the gear 17 to rotate.
Receives a force in the direction of strengthening the meshing and can stably transmit the rotation. In order to cancel the rotational force of the arms 12 and 15, the sun gears 10 and 13 and the planet gears 11 and 14 are preferably gears having the same number of teeth.

Connected are an X contact switch SW3 provided in the shutter, a known release switch SW4, a rewind switch SW5 that is operated when starting a rewind operation, and a back cover switch SW6 that detects opening and closing of the back cover. There is. The drive circuit 101 includes a motor 1 and a front curtain magnet 1.
02, the rear curtain magnet 103, the solenoid 84, etc. are connected.

Next, the operation of this embodiment will be described. Figure 4
FIG. 4 is a timing chart for explaining the operation of this embodiment. First, a normal release operation will be described.

After the film is loaded into the camera, the back cover is closed and the first frame is searched, the release switch S
When W4 is turned on, at time A shown in FIG. 4, the release solenoid 84, the front curtain magnet 102, and the rear curtain magnet 103 are energized.

By energizing the solenoid 84,
The movable contact piece 84a shown in FIG. 2 moves to the right, the release locking lever 83 rotates right, and the engaging portion 83a and the engaging portion 8 are moved.
0c is unlocked. As a result, the mirror-up lever 80 is rotated clockwise by the urging force of the spring 79 to shift the quick return mirror to the mirror-up state as described above.

At this time, the mirror up lever 80
The convex portion 80d contacts the engaging portion 74b of the locking lever 74 and rotates the locking lever 74 counterclockwise to unlock the engaging portion 74a and the engaging portion 72c of the shutter charge lever 72. Therefore, the shutter charge lever 72 has the spring 73.
The urging force of turns the counterclockwise to make the shutter curtain ready for traveling. At this point in time, since the front curtain magnet 102 and the rear curtain magnet 103 of the shutter are energized, the front curtain and the rear curtain are held in the charged state.

As shown in FIG. 6, the mirror up lever 8
The mirror charge lever 78 rotates counterclockwise with the right rotation of 0. When the mirror charge lever 78 is rotated counterclockwise and the shutter charge lever 72 is rotated counterclockwise, the engaging portions 72a, 78 are rotated.
a moves to the right respectively and engages with the engaging portion 3 of the lever 36.
6b is also pushed to the right.

Here, in FIG. 5, the lever 36 rotates clockwise about the shaft 30b by the movement of the engaging portion 36b, the engaging portion 36b and the pin 35 come into contact with each other, and the lever 33 also moves about the shaft 30b. Turn right as.

As a result, the engagement between the engagement portion 33a and the pin 22 is released, and the four-bar linkage 60 is rotated clockwise by the urging force of the spring 38 so that the gear 11 and the gear 20 are engaged with each other and the gear 14 and the gear 17 are engaged. The meshing (not shown in FIG. 5) is released. The state around the four-bar linkage and the charge lateral lever 30 at this time is shown in FIG. 5, and the state of the charge mechanism section of the mirror and the shutter is shown in FIG.

After the operation immediately after the release is performed in this way, in this embodiment, as shown in FIG.
[s], the power supply to the solenoid 84 is cut off. As a result, the movable contact piece 84a becomes free, and the release locking lever 83 tries to rotate counterclockwise due to the biasing force of the spring 85. However, at this time, since the mirror up lever 80 is in the up state, the engagement portions 83a and 80c are not locked. Further, after a lapse of time (X [ms] in FIG. 4) until the mirror rises and stabilizes, the energization of the front curtain magnet 102 is cut off. And
After a predetermined shutter time, the rear curtain magnet 103
The power supply to is also cut off. As a result, the leading and trailing curtains sequentially run, and the exposure operation to the film is performed.

Next, after the power supply to the rear curtain magnet 103 is cut off, a predetermined time (Y [ms] in FIG. 4) is opened and the motor 1 is normally rotated (counterclockwise in FIG. 1). Then, the sun gear 6 also rotates counterclockwise, the arm 8 rotates counterclockwise, the gears 7 and 9 mesh, the gear 10 rotates clockwise, and the gear 11 rotates counterclockwise.

As described above, since the four-bar linkage 60 is rotated clockwise by the action of the spring 37, the gear 11 and the gear 20 mesh with each other, and the rotational force is transmitted to the gear 20, Turn the cam 21 clockwise. As shown in FIG. 7, when the cam 21 starts rotating to the right, the cam surface of the cam 21 comes into contact with the shaft 30 a provided on the charge lateral lever 30, and the charge lateral lever 30 rotates left about the shaft 31.

When the charge lateral lever 30 is turned counterclockwise, the engaging portion 30c becomes the engaging portion 72 of the shutter charge lever 72.
a and the engaging portion 78a of the mirror charge lever 78 are moved leftward from the state of FIG. Along with this, the shutter charge lever 72 rotates counterclockwise, the mirror up lever 80 rotates clockwise, and the state of FIG. 2 is restored again.

FIG. 7 shows the state immediately before the charging of the charge lateral lever 30 by the cam 21 is completed. With the counterclockwise rotation of the charge lateral lever 30, the shaft 30b provided on the charge lateral lever 30 rotates in the counterclockwise direction about the shaft 31. Immediately before the completion of charging, the engaging portion 33a of the lever 33 is again engaged with the pin 22 by the urging force of the spring 34.

At this time, the lever 36, which is rotating the lever 33 clockwise at the time of release, has the engagement portion 72a of the shutter charge lever 72 with which the engagement portion 36b is in contact, and the engagement portion of the mirror charge lever 78. 78a move to the state shown in FIG. 2 by the charge lateral lever 30, respectively, so that the urging force of the spring 37 interlocks with the shaft 30b.
Turn left around and 36a will move away from pin 35
Can turn left.

The motor 1 further rotates in the normal direction from the state shown in FIG.
When the cam 21 rotates, the cam 21 makes one rotation and returns to the state of FIG. 1 again. At this time, the charge side lever 30
Is rotated clockwise around the shaft 31 by the urging force of the spring 32, and the shaft 30b provided on the charge lateral lever 30 moves, so that the lever 33 maintains the engagement between the engaging portion 33a and the pin 22. , The four-bar linkage 60 rotates counterclockwise, and the gear 14 and the gear 17 mesh with each other.
This is the time point B shown in FIG.

Further, when the motor 1 continues to rotate in the normal direction, this time, as shown in FIG. 1, the gears 10, 13, 14, 17,
The rotational force is transmitted in the order of 18, and the spool 19 turns left,
The film is wound up. When the film winding is started, as described above, the sprocket 50 rotates and the winding pulse is output from the sprocket switch SW1. Then, when the winding of one film, that is, 16 pulses in this embodiment is completed, the spro standard switch SW2 is also turned on. At this time, one shooting operation is completed by stopping the motor 1 (see FIG.
Point C).

When the motor 1 is stopped, the number of pulses from the spro switch SW1 is counted, and the motor 1 is pulse-driven as appropriate before the completion of winding to reduce the rotation and improve the stopping accuracy. Good.

As described above, in this embodiment, 1
Since the motor 1 is constantly rotating in one direction during one shooting operation, the winding speed can be improved.

Next, the operation of this embodiment when the film is loaded and at the end of the film will be described. When the film is loaded and the back cover is closed, the back cover switch SW6 is turned on. The control circuit 100 performs the film idling control when the release switch SW4 is turned on for the first time after the back cover switch SW6 is turned on (at the time point D shown in FIG. 4).

At this time, the motor 1 starts normal rotation and winds the film. If the mirror and shutter have not been charged, as described above, 4
Since the joint link mechanism 60 rotates clockwise and the gear 11 and the gear 20 are meshed with each other, they are charged first, and then the winding operation is automatically started.

When the film winding is started, a pulse is output from the spro switch SW1. Therefore, a predetermined winding amount, 48 pulses for three frames in this embodiment, is wound, and the spro standard is first started from that point. The film is stopped when the switch SW2 is turned on (Fig. 4
Time point E). As a result, when the winding of one frame is completed, the phase of the film and the switch is adjusted so that the sprout reference switch SW2 is always turned on.

Next, the operation of the film end will be described. At the end of the film, the film cannot be fed any more during winding, so the number of pulses from the spro switch SW1 does not become 16 pulses. If 16 pulses are not output from the spro switch SW1 even after a lapse of a predetermined time (shown as a timeout in FIG. 4) during the winding operation (time point F shown in FIG. 4), the control circuit 100 causes the film end. Then, the motor 1 is stopped.

After that, when the rewinding switch SW5 is turned on, the motor 1 starts reverse rotation in response to a command from the control circuit 100 (at time G shown in FIG. 4).

At the time of rewinding, the reverse rotation of the motor 1 causes
In FIG. 1, the gear 2 rotates clockwise, and the sun gear 6 rotates clockwise through the gears 3 to 5. Then, the arm 8 rotates right by the action of the friction mechanism provided between the arm 8 and the planet gear 7, the gears 7 and 40 mesh, and the pulley 41 rotates right.
This rotation is transmitted to the pulley 43 by the belt 42, and the fork 43a is rotated clockwise to rewind the film in the cartridge.

When the rewinding of the film is started, the sprocket 50 rotates, so that the sprocket switch SW1 outputs a pulse. Then, at the end of rewinding, when the tip of the film separates from the sprocket 50,
The pulse stops.

Therefore, when the output from the spro switch SW1 disappears for a certain period of time, the control circuit 100 (Z in FIG. 4).
(Indicated by [ms]), it is determined that the rewinding is completed, and the motor 1 is stopped (at the time point H shown in FIG. 4).

[0060]

As described in detail above, according to the present invention, since the film is fed by a single motor, it is small and low in cost, and the motor of the motor can be operated during one photographing operation. Since the rotation direction does not change, it is possible to obtain a spool drive type camera drive device that has a high winding speed and excellent winding sound.
