Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an instant camera in which a lens board having a photographing lens incorporated therein can be raised and lowered.

[0002]

2. Description of the Related Art In an instant camera, the screen size of a film unit loaded in the camera is significantly larger than that of a 135 film, and the developing solution pod is cleaved after taking a picture so that the developing solution is stored in the film unit. The shape of the camera tends to increase in size because, for example, the deployment roller for spreading the paper must be built into the camera. For this reason, as known from Japanese Patent Laid-Open No. 4-151632, a lens board incorporating a taking lens can be raised and lowered with respect to a main body portion provided with a film pack storage portion, and the lens board can be used when not in use. Various structures have been devised that can be folded compactly.

In an instant camera having a lens board that can be raised and lowered, a bellows is generally used to connect the main body and the lens board in a light-tight manner when the lens board is erected. If the bellows is exposed to the outside as it is with the lens board raised, the bellows may be pushed in by the hand holding the camera, and vignetting may occur in a part of the photographing optical path. In this regard, in the instant camera described in the above publication, a cover-shaped lens stay is pivotally attached to the front edge side of the lens board, and the lens stay covers the lower part of the bellows when the lens board is erected. It is designed so that the bellows will not be pushed in sometimes.

[0004]

In the instant camera described in the above publication, at the time of shooting, the side surface of the main body on the side where the shutter button is provided is grasped by the right hand, and the lens stay wrapping under the bellows is lowered by the left hand. Since it was supported from the side, it was difficult to hold the camera, and it was insufficient in terms of mobility. Further, in the case of an instant camera that does not have the plate-like lens stay as described above, the camera must be held without pushing the bellows, and there is a drawback that it is difficult to operate. Furthermore, if the lens board protrudes when not in use and an inadvertent shock is applied, the optical axis of the shooting lens will shift and this will cause a failure.Therefore, a mechanism for locking the lens board in the prone position is also required. Was becoming.

The present invention has been made to solve the above problems, and makes it easy to hold the camera during photography without impairing the compactness of the camera when it is carried, and the lens board stands up carelessly when not in use. The purpose is to provide an instant camera that does not.

[0006]

In order to achieve the above-mentioned object, the present invention is stored in a main body portion provided with a film pack storage portion along a protruding position protruding from the side surface and a side surface of the main body portion. A movable gripping member is provided between the gripping member and the storage position, and when the gripping member is at the storage position, the standing of the lens board is locked. Further, a click mechanism is provided to stop the gripping member at the projecting position and the storage position respectively, and further, a part of the gripping member at the storage position is fitted into the groove of the lens board at the fall position to mount the lens board. Locking in the prone position is also an effective means for implementing the present invention.

[0007]

When the grip member is moved to the projecting position from the side surface of the main body, the lens board is unlocked and the lens board can be erected at the photographing position. Since the gripping member projects to the side surface of the main body, the camera can be held securely by gripping the gripping member.

[0008]

1 and 2 showing an instant camera using the present invention, this camera has a thin box-shaped contour, and a main body portion 2 having a film pack storage portion provided therein.
And a lens board 3 which is rotatably and axially attached to the main body 2. In the upright position shown in FIG. 1, the lens board 3 is locked by the stay 5, and when the stay 5 is pushed up in the direction of the arrow, the lock is released and the lens board 3 can be folded in the lying position shown in FIG. it can.

A bellows 6 is provided between the lens board 3 and the main body 2 to cover the photographing optical path between the photographing lens 15 incorporated in the lens board 3 and the exposure frame in the main body 2 in a light-tight manner. ing. When the lens board 3 is folded, the bellows 6 is folded between the lens board 3 and the main body.

A stroboscopic light emitting portion 7, a finder 8, a shutter button 9 and the like are provided on the upper front surface of the main body portion 2, and a discharge port 10 for discharging the exposed film unit is provided on the upper surface. A developing roller that crushes and expands the developer pod while the exposed instant film unit is transferred toward the discharging port 10 is built in the discharging port 10.

A side surface 2a on the right side of the front of the main body 3
The gripping member 4 is axially attached to the shaft by a shaft portion 17. Bending pieces 4a and 4b are integrally formed on the front edge and the rear edge of the grip member 4. As shown in FIG. 3, the bent piece 4b on the trailing edge side has a recess 22 formed on the inner surface side thereof, and a semicircular cutout 23 formed on the end edge. The click ball 20 incorporated in the step surface 2c, which is lower than the back surface 2b of the main body 2, is fitted into the recess 22 and the notch 23. As a result, the gripping member 4 is click-stopped at two positions, the protruding position protruding from the side surface 2a of the main body 2 and the storage position folded along the side surface 2a. It is also possible to use a separately provided locking mechanism to lock the gripping member 4 at the storage position and the protruding position.

On one side surface of the lens board 3, a groove 13 having a V-shape is formed following the shape of the bent piece 4a on the front edge side of the grip member 4. Then, when the grip member 4 is folded to the storage position while the lens board 3 is rotated to the lying position shown in FIG. 2, the bent piece 4 a is fitted into the groove 13.

The operation of the above configuration will be described below. In this instant camera, when not in use, the lens board 3 is folded to the lying position and the gripping member 4 is folded to the storage position as shown in FIG. In this state, the bent piece 4a of the grip member 4 is fitted in the groove 13 formed on the side surface of the lens board 3, and the click ball 20 is fitted in the recess 22 of the grip member 4. Therefore lens board 3
Is in a locked state, and the lens board 3 does not stand up carelessly when the camera is carried.

In use, the holding member 4 is first pulled out to the protruding position shown in FIG. In this pulled-out position, the click ball 20 engages with the notch 23 and click-stops the gripping member 4 at the projecting position, so that the gripping member 4 does not return to the storage position even if some external force is applied. When the gripping member 4 moves to the protruding position, the bent piece 4a on the front edge side of the gripping member 4 comes out of the groove 13 of the lens board 3 and the lens board 3 is unlocked.

After that, when the lens board 3 is lifted and rotated to a predetermined upright position, the stay 5 performs a locking action, and the lens board 3 is locked at the photographing position so that photographing can be performed as shown in FIG. It becomes a state. In this state, since the gripping member 4 projects from the side surface 2a of the main body portion 2, the photographer grips the side surface of the main body portion on the side where the shutter button 9 is provided with the right hand, and further wraps the gripping member 4 with the left hand. Can be grasped. By gripping the main body 2 with the left and right hands in this way, the camera can be firmly held without touching the bellows 6, and the camera can be freely oriented in the shooting direction.

After the photographing is finished, the stay 5 is pushed up to unlock the lens board 3, so that the lens board 3 can be pushed down and folded as shown in FIG. Then, when the grip member 4 is strongly pushed, the grip member rotates so as to get over the click ball 20. Then, the click ball 20 engages with the concave portion 22 and the grip member 4 is locked in the storage position. By returning the gripping member 4 to the storage position, the bent piece 4a is fitted into the groove 13 of the lens board 3, and the lens board 3 is locked at the unused position.
