Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lens-fitted photo film unit having a built-in strobe battery, and a film hoisting device for driving a motor using the power supply of the battery. Is.

[0002]

2. Description of the Related Art A simple photographing mechanism and a strobe unit are provided so that anyone can easily enjoy photographing, and it is defined by the international standard ISO 1007-1979.
A film unit with a lens (hereinafter referred to as a "film unit") in which a 35-type photographic film with a cartridge is preloaded is well known.

The film unit has a main body base for accommodating a photographic film with a cartridge, a front cover attached to the front surface of the main body base, and a rear surface attached to the main body base.
It consists of a rear cover that makes the photographic film light-tight between them, and a strobe unit that is sandwiched between the main body base and the front cover.The main body base has a taking lens, a shutter mechanism, a film winding mechanism, And a film counter mechanism and the like are incorporated. The base of the main unit is equipped with a cartridge storage room and a film storage room.The cartridge storage room is loaded with a cartridge, and the film storage room is loaded with a film roll that is a roll of a photo film taken out from the cartridge. To be done. The winding knob is engaged with the spool of the cartridge and has teeth formed on the outer circumference thereof.

When the winding knob is rotated in the film winding direction, the photographic film is transferred, and the sprocket is rotated by the transfer of the photographic film. When the photo film is fed by one frame, the sprocket rotates once and the film winding stop mechanism operates. When the film winding mechanism operates, the rotation of the sprocket and the rotation of the winding knob are prohibited. The shutter mechanism is charged during this time.

When stroboscopic photography is performed, the strobe charging switch is depressed. By this pressing operation, the main capacitor is charged with a high voltage obtained by boosting the power supply of the AA battery incorporated in the strobe unit. After that, when the shutter button is pressed, the shutter operates. At this time, the sync switch of the strobe unit is turned on, strobe light is emitted from the strobe light emitting portion toward the subject, and the operation of the film winding mechanism is released.

After one shot is taken, the prescribed number of shots are finished, and after the last frame is shot,
All the photo films are stored inside the patrone by rotating the winding knob, and the film winding stop mechanism does not operate after that, so the winding knob spins. As a result, the user directly submits the film unit to the photo lab. At the photo lab, a part of the film unit is opened, the cartridge is taken out, and processing such as development and printing is performed using the existing development processing system, and the print photograph and the film negative are returned to the user.

By the way, in the film unit, since the next photographing cannot be performed unless the turning operation of the winding knob is performed for each photographing, there is a possibility that the operator may forget the turning operation of the winding knob and miss a photo opportunity. . In order to eliminate such an adverse effect, a film winding device detachably attached to the film unit is desired.

When the film winding device is considered, it is desirable to have a detachable structure so that the film winding device can be used repeatedly. Therefore, when mounted, a connection gear connected to the tooth row on the outer periphery of the winding knob of the film unit, a motor for rotating the connection gear, and a power supply for the motor are required. The power source of the motor is preferably a widely used AA battery.

[0009]

However, in addition to incorporating a motor, a gear, etc. in the film winding device, even incorporating an AA battery not only increases the cost but also increases the size of the device itself. There is a fear that it will be difficult to hold. Furthermore, when the battery is exhausted, it is necessary to remove it from the film unit and replace it with a new battery.

Further, in the film unit, even if stroboscopic photography is performed on all the frames of the photographic film, the capacity of the built-in strobe battery is not exhausted. This battery is collected in the factory together with the used film unit after the cartridge is taken out at the developing place and is collected by the battery collecting company there.

The present invention has been made in order to solve the above problems, and is a film winding device which is inexpensive and small in size without requiring the user to perform a troublesome battery replacement operation. It is an object of the present invention to provide a film unit in which a strobe battery is used as a power source of a film winding device in order to effectively use the battery.

[0012]

In order to achieve the above object, the present invention utilizes a strobe battery built in a film unit to drive a motor of a film hoisting device attached to the strobe battery. It was done. Therefore, the film unit is provided with an external connection terminal for supplying the power source of the strobe battery to the outside, and the film winding device is connected to the external connection terminal when the film unit is mounted, A terminal is provided for supplying the power of the battery to the motor. Since the external connection terminal is required only when the film winding device is mounted, it is usually desirable to hide it. Therefore, it is sufficient to cover the film unit with an outer case and cut it to form perforations so that the external connection terminals are exposed. Further, according to the invention in which the pocket portion is provided outside the film unit, the pocket portion can serve both as the coupling between the film winding device and the film unit and for the electrical connection.

In the clutch gear 79, the claw 79a engages with the claw 82a when the rotation operation of the winding knob 16 is permitted, and the drive transmission position for transmitting the drive of the motor 4 to the coupling gear 5 and the winding gear 16 of the winding knob 16. The load when the rotation operation is prohibited moves downward of the shaft 5b to disengage the claw 79a from the claw 82a, and moves to a drive release position where the drive of the motor 4 is not transmitted to the coupling gear 5. A switch 81 is arranged on the lower surface of the clutch gear 79.

A shutter release plate 80 is arranged above the disc 82. A shutter release button 24 is integrally formed on the upper surface of the shutter release plate 80. A pressing pin 80a for pressing the shutter button 15 of the film unit 11 is formed integrally on one end side of the shutter release button 24, and a sliding opening 80b is slidably formed on the other end side of the outer circumference of the disk 82. Has been done. The edge of the sliding opening 80b guides the shutter release plate 80 moving along the direction of the shaft 5 while sliding on the outer periphery of the disk 82 when the shutter release button 24 is pressed. By this movement, the push-down pin 80a pushes down the shutter button 15, and the sliding opening 80b
Around presses the clutch gear 79 to move it to the drive release position.

The switch 81 is a push-push type switch, and when the switch lever 81a is projected, the internal contact is in the ON state (closed state). The switch lever 81a is pushed into the housing 81b by the movement of the clutch gear 79 to the drive release position. The switch lever 81a slides in the housing 81b together with the guide 81c fitted in the linear groove.

When the switch lever 81a is in the protruding position, the guide 81c is at the position P1 shown in FIG. When the switch lever 81a is sufficiently pushed into the housing 81b, the guide 81c moves to P2 shown in FIG.
In the position. Then, the guide 81c is returned to the position P3 shown in the figure together with the switch lever 81a by the spring (not shown) built in the housing 81b, and the switch lever 81a is held at this position by the internal lock mechanism. This switch lever 81a is P3

When the switch lever 81a is pushed in again by the length L and the guide 81c moves from the position P3 to the position P2, the internal lock mechanism is released, and the spring returns the guide 81c to the original position together with the switch lever 81a. Then, the internal contact switches to the ON state when returned. At this time, the guide 81c is moving from the position P2 to the position P1.

The circuit structure of the film winding unit 10 is as shown in FIG.
1 and the motor 4 are connected in series. And
In the initial state of the film winding unit 10, the switch 81 is in the ON state.

Next, the operation of the above configuration will be described. In the initial state of the film winding unit 10, the switch 81 is in the ON state as described above, and as shown in FIG. 10, the clutch gear 79 is in the drive transmission position. Therefore, the shutter release plate 80 is in a state where the shutter release button 24 is exposed at the opening of the housing 8a.

When the film winding unit 10 is mounted on the film unit 11, first, the pair of cutout portions 6 provided on the outer case 13 are cut along the perforations. As a result, on the left side surface of the film unit 11,
The external connection terminals 30I and 30J are exposed. After that,
The film unit 11 is inserted into the opening 9 of the film winding unit 11 from the left side surface thereof. By this insertion, the connecting gear 5 causes the tooth row 16a on the outer circumference of the winding knob 16 to be formed.
And a pair of external connection terminals 30i, 30
j contacts the pair of terminals 7a and 7b, and the driving of the motor 4 is started.

The motor 4 is driven by the gear 4a, the gear 75,
76, gears 77, 78, and clutch gear 79. Since the clutch gear 79 is in the drive transmission position, the drive of the motor 4 is transmitted to the coupling gear 5 via the disc 82. As a result, the winding knob 16 of the film unit 11 rotates in the film winding direction.

When the winding knob 16 is rotated, the driven sprocket 57 is rotated along with the transfer of the photographic film 31a, and when the driven sprocket 57 is rotated once, the film winding mechanism is operated. In this film winding stopping mechanism, the claw 53a of the locking lever 53 enters the notch 55a of the cam member 55 to inhibit the rotation of the driven sprocket 57, and at the same time, the locking lever 53 moves slightly clockwise about the shaft 47. Rotate to the position of the locking lever 53
3d engages with the teeth 16a of the winding knob 16 to prohibit the rotation operation of the winding knob 16.

When the film winding stopping mechanism operates, a sudden load is applied to the connecting gear 5, causing slippage on the engagement surface between the claw 79a and the claw 82a, and the clutch gear 79 moves to the drive release position. When the switch lever 81a is pushed toward the inside of the housing 81b by the movement of the clutch gear 79, the guide 81c moves from the position P1 to the position P2. After that, the guide 81c is moved to the position P by the spring.
3, the internal lock mechanism holds this state.
