て撮影する予備巻方式のカメラに関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a pre-winding type camera in which a film stored in a cartridge is pulled out in advance, wound onto a spool, and then rewound frame by frame from the spool to be photographed. .

タを設けるとカメラが大形化する不具合がある。Recently, cameras have become more and more electric, and functions such as winding the film one frame during shooting, rewinding the film after shooting, and adjusting the focal length are all now electric. In this case, in a normal winding camera that has a variable focal length mechanism such as a zoom mechanism or a tele-wide switching mechanism, the focal length can be adjusted electrically in addition to the single-frame winding mechanism and rewind motor. If a dedicated motor is provided for the camera, there is a problem in that the camera becomes larger.

りラッチ機構は複雑な機構を必要とする欠点がある。If one motor drives the one-frame winding mechanism, the rewinding mechanism, and the variable focal length mechanism, there is a drawback that the latching mechanism requires a complicated mechanism because the three directions can be switched.

戻すようにしている。Conventionally, in a normal winding type camera, in addition to the first clutch that switches between one-frame winding and rewinding, a second clutch that switches between the rewinding mechanism and the variable focal length mechanism is used, and two clutches are used. A camera has been proposed that selectively switches among three mechanisms: an l-frame winding mechanism, a rewinding mechanism, and a variable focal length mechanism (Japanese Utility Model Publication No. 110835/1983). In this case, first switch the first clutch to the one-frame winding mechanism to wind up one frame of film, then switch the first clutch from the one-frame winding mechanism to the rewind side, and then switch the second clutch to the rewind side. Switch to the variable distance mechanism to drive the lens, and after releasing the shack, switch the first clutch to the one-frame winding mechanism again. Repeat this operation to photograph all frames. After shooting, move the first clutch to the rewind side. At the same time, the second clutch is switched to the rewinding mechanism to rewind the film.

There is a drawback that a complicated switching mechanism is required between this external operating member.

のカメラが提案されている。On the other hand, a pre-winding camera has been proposed in which the entire length of the film is pre-wound onto a take-up spool, and each frame is rewound into the film cassette while the frame is advanced and the film is taken. .

Rewind the film one frame at a time into the cartridge and shoot.

目的としている。Focusing on the fact that if a camera with such a pre-winding system is adopted, pre-winding, frame winding, and focal length adjustment can be performed with a simple mechanism, the present invention has developed a system that allows the rotation direction of the motor to be adjusted without using a complicated switching mechanism. The object of the present invention is to propose an electric device for a camera that can easily switch the rotational force of a motor to a preliminary winding mechanism, a one-frame winding mechanism, and a variable focal length mechanism by simply changing the mechanism.

4, the clockwise rotation of the gear 12 of the motor 10 rotates clockwise as shown by the two-dot chain line in FIG. It meshes with the gear 32 of the winding mechanism. Further, when the gear 12 rotates counterclockwise and the arm 26 rotates counterclockwise, the pin 26A of the arm 26 presses and rotates the locking lever 74 clockwise against the force of the spring 30. As shown in FIG. 4, the pin 26A is eventually locked in the recess 74A of the locking lever 74.

完全にギア３４から離される。When the back cover 72 is opened by rotating it counterclockwise in FIG. 1 about its rotation axis 73, the back cover 72 opens as shown in FIG.
Since the abutting portion 72Δ of is separated from the receiving portion 66A of the release lever 66, the release lever 66 is rotated counterclockwise about the shaft 68 by the biasing force of the spring 70. Release lever 66
As mentioned above, the strength of the spring 70 is greater than that of the spring 30, so when the release lever 66 is rotated counterclockwise, the locking lever 74, which the pin 66B of the release lever 66 and its protrusion 74B are in contact with, is released. The pin 26 of the arm 26 is rotated clockwise against the biasing force of the spring 30, as shown in FIG.
A is disengaged from the recess 74A of the locking lever 74. Furthermore, when the release lever 66 is rotated counterclockwise by the biasing force of the spring 70, the protrusion 66C of the release lever 66 presses and rotates the protrusion 26B of the arm 26, and the arm 26 is forcibly rotated clockwise. As a result, the planetary gear 28 that was meshing with the gear 34 is forcibly separated from the gear 34,
It will be reset. As a result, the gear 32 is completely separated from the gear 34 even when the gear 32 and the gear 34 are in mesh with each other and are difficult to separate.

is fitted into the recess 66B and locked. Therefore, even if the gear 12 of the motor 10 rotates clockwise in this state, the gear 28 will not run away from the gear 34. When the gear 12 of the motor 10 rotates counterclockwise in this state, the rotational force of the motor 100 is transmitted to the sun gear 46 through the gears 12 to 28 and further through the gears 34 to 44. When the gear 12 of the motor 10 is rotated counterclockwise, the arm 48 of the sun gear 46 rotates counterclockwise, and the planetary gear 50 meshes with the gear 54 as shown in FIG. As a result, the fork portion 60 engages with the patrone shaft.
rotates, and one frame of film is taken up.

ズされフィルムが露光されることになる。The clockwise rotation of the gear 12 of the motor 10 causes the arm to rotate clockwise, causing the planetary gear 50 to separate from the gear 54 and become engaged with the sun gear 56 of the switching mechanism, as shown in FIG. When the zoom lever 86 is set to the telephoto position as shown in FIG. 2, when the motor 10 is rotated by a predetermined amount, the gear 78 rotates in the telephoto direction, and the lens barrel 100 is moved to the zoom side. will be moved to Further, when the zoom lever 86 is set to the wide position as shown in FIG. 3, the gear 78 rotates in the wide direction, and the lens barrel 10
0 is moved to the wide side. After focus adjustment, the shirt is released and the film is exposed.

The rotational force is transmitted to the sun gear 46 via the arm 48. The arm 48 rotates counterclockwise again, and the arm 48 rotates counterclockwise to the gear 5 of the one frame feed mechanism.
It will mesh with 4. In this state, when the motor 10 rotates counterclockwise by one frame, the fork portion 60 winds up the film (not shown) by one frame.

After shooting, the film is completely wound in the cartridge, and when the lid 72 is opened, the release lever 66 is operated as described above, the arm 26 is released from the locking lever 74, and the planetary gear is forcibly moved. 28 is separated from gear 34 and reset. In the above embodiments, the focal length variable mechanism may be either a zoom mechanism or a tele->id bifocal mechanism.
