Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Field of Industrial Application) The present invention mainly relates to a small camera such as a pocket camera in which a 110 (one-ten) type film is used.

(Prior Art) Conventionally, in this type of small-sized camera, a film winding base provided with a film winding mechanism at an appropriate position is integrally provided at the lower end of the left side surface of the camera body so as to project laterally.

(Problems to be solved by the invention) However, since the film winding stand remains protruding to the side of the lower end of the left side surface of the camera body even when it is not used, not only is the camera body bulky and large The appearance was also unfavorable.

Therefore, this invention was devised to solve the above-mentioned problems, and when not in use, not only can the entire camera be made compact and downsized, but also the appearance can be improved. It is intended to provide a small camera that can be improved.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention has a film winding mechanism at a proper position at a lower end or an upper end of one side surface of a camera body. The film winding base provided was supported so as to be foldable upward or downward.

(Operation) By means of the above technical means, the film winding base can be swung upward or downward to be folded when not in use.

(Embodiment) An embodiment of the present invention will be described below with reference to the drawings.

As shown in FIGS. 1 and 2, the present invention is a substantially tongue-shaped film in which a film winding mechanism 2 is provided in a front portion and an inner portion at a lower end portion of a left side surface of a camera body 1 having a substantially cubic shape. The hoisting base 3 is supported by a shaft pin 4 so as to be foldable upward.

As shown in FIGS. 3 and 4, the film winding base 3 has a film winding plate 5 supported on the lower end of the left side surface of the camera body 1, and a lower surface of the film winding plate 5. The film winding mechanism 2 is covered with a cover plate 6 which is removably fitted to (a surface that does not come into contact with the left side surface of the camera body 1 when folded). A recess 7 for inserting the winding driven gear B of the film A is provided so as to be opened rearward, and a 110-type film A is wound on the front portion of the recess 7 so as to mesh with the winding driven gear B. The hoisting drive gear 8 of the hoisting mechanism 2 is rotatably attached to the shaft, and the hoisting drive gear 8 in the front portion of the lower surface of the film hoisting plate 5 is coaxial with the hoisting drive gear 8.
A hoisting dial 9 for hoisting the mold film A is rotatably fixed so that a part thereof is exposed to the front. In the vicinity of the rear part of the winding dial 9 on the lower surface base end side of the film winding plate 5, by rotating the winding dial 9 or pressing the shutter buttons 10 and 11 on the upper front part and the lower front part of the camera body 1. The engaging portion 13 that engages with the tip of the shutter operating plate 12 that swings in the front-rear direction and the engagement gear 14 that engages with the locking gear 14 on the outer peripheral surface of the hoist dial 9 by swinging the shutter operating plate 12 in the front-rear direction A dial stopper (16) including a locking claw portion (15) that is locked to is supported by a shaft portion (17) so as to be swingable in the front-back direction. Further, in the vicinity of the rear part of the winding dial 9 on the lower end side of the lower surface of the film winding plate 5, the leading end is a locking gear of the winding dial 9.
A reverse rotation preventing spring 18 is provided to prevent the reverse rotation of the hoisting dial 9 by locking it diagonally.

Further, although the film winding base 3 is described and illustrated as being supported by the lower end portion of the left side surface of the camera body 1 so as to be foldable upward by the shaft pin 4, the invention is not limited thereto. , Foldably supported downward on the upper end of the left side surface of the camera body 1, or foldable upward or downward on the lower end or upper end of the right side surface of the camera body 1; It may be supported by a lower end or an upper end of the left side surface or the right side surface of the main body 1 by a hinge so as to be foldable upward or downward.

Reference numeral 19 in the drawing is a locking projection for locking and winding up on the perforation of the 110 type film A,
Is a film mounting plate rotatably supported on the lower end of the rear surface of the camera body 1, and reference numeral 21 is a lens. Furthermore,
Reference numeral 22 is a band, which can be used as a small watch-type camera by fitting it on an arm. In this case, if the main body of the watch is attached to the outer surface of the film mounting plate 20 on the rear surface of the camera body 1,
It is even better as a small watch-type camera.

Next, the use state will be described. As shown in FIGS. 2 and 5, the film winding base 3 swings laterally around the shaft pin 4 to open in a horizontal state, and the film mounting plate 20 is opened rearward, so that the hoisting drive gear 8 of the film hoisting mechanism 2 in front of the concave portion 7 of the film hoisting plate 5 meshes with the hoisting driven gear B of the 110-type film A on the rear surface of the camera body 1. 110
The mold film A is fitted from the rear and the film mounting plate 20 is closed to the front. When taking a picture, when the winding dial 9 of the film winding mechanism 2 is rotated, the 110-inch film A is wound up via the winding drive gear 8 and the winding driven gear B, and at the same time, the shutter operating plate 12 Swings forward,
When the locking claws 15 are locked to the locking teeth 14 on the outer peripheral surface of the winding dial 9 and the shutter buttons 10 and 11 are pressed, the shutter operating plate 12 swings rearward, and the locking claws 15 move. The winding dial 9 is disengaged from the locking tooth portion 14. By these operations, after taking a picture, the 110 type film A is sequentially wound.

In this case, as the film winding mechanism 2 of the film winding base 3, a part of a dial stopper 16 which is swingably supported in the front-rear direction in the vicinity of the rear portion of the winding dial 9 on the lower surface base end side of the film winding plate 5 is supported. By providing the engaging portion 13, when the film winding base 3 is swung to the side and opened horizontally in use, the winding dial 9 is rotated and the shutter buttons 10 and 11 of the camera body 1 are operated. An engaging portion 13 of the dial stopper 16 of the film winding mechanism 2 of the film winding base 3 is attached to the front end portion of the shutter operating plate 12 which swings in the front-rear direction when pressed.
Can be reliably engaged.

[Advantages of the Invention] This invention folds a film winding base 3 having a film winding mechanism 2 in place at the lower end or the upper end of one side of the camera body 1 as shown above. Since it is configured to be supported so that it can be folded up, the entire camera can be made compact by swinging the film winding base 3 upward or downward when not in use to make it compact. The appearance of is very good.
