BACKGROUND OF THE INVENTION Field of the Invention The present invention relates to still cameras, and more particularly to single-lens reflex-cameras (SLRs) and film magazines that can be used to shoot in horizontal or vertical sizes in small or medium cameras. It is about.

An object of the present invention is to provide a still camera that can facilitate selective shooting in the horizontal or vertical size without rotating the camera body.

The above object of the present invention can be achieved by the following features of the present invention:

a) The film magazine of the present invention is spaced apart by about 90 ° spherical angle to facilitate horizontal size photographing with the picture gate of the film magazine lying down and vertical size photographing with the picture gate upright. It is optionally inserted into the camera body in two positions;

b) within the housing of the film magazine, a drive motor for film winding and a drive motor for film slide rails and a film press plate forming a film feed passage;

c) a slide in the magazine housing to seal the magazine's picture gate before removing the film magazine from the camera body to change the photographing position;

d) The contact portion between the camera body and the film magazine is formed to be rotationally symmetrical with respect to the picture gate closure and the electrical contact portion, and the magazine side blocking member and the camera side electrical contact portion are respectively a supplemental-blocking member and a supplementary-contact. Wealth is prepared. The blocking portion and the contact portion are mounted on either the camera side or the magazine side in double spaced at about 90 ° spherical angle, respectively;

When the film magazine is mounted on the camera body with the picture gate lying horizontally, the camera can shoot horizontally. When the film magazine is mounted 90 ° vertically, it can be used for vertical size shooting. have. The mounting portion between the camera body and the film magazine can be formed particularly simply by installing a drive motor for film winding and a member necessary for film movement in the magazine housing. In order to change the mounting of the film magazine to the camera body at a spherical angle of about 90 °, it is required to overlap the supplemental blocking member or the supplemental electrical contact part, so that the device is overlapped with either the camera body or the film magazine.

The slide of the film magazine can be quickly and simply closed and closed the picture gate, it is possible to quickly replace and replace the film magazine.

In particular, in order to solve the structural problem according to the present invention in a simple but effective way can be solved by providing a rectangular magazine insertion hole on the back of the camera body to accommodate the insertion aid mounted on the magazine housing.

In particular, for the purpose of saving space and facilitating the operation of the slide of the film magazine according to the present invention, the slide is freely rotated inside the magazine housing and flexibly formed to allow manual operation from the outside. External operation of this slide can use, for example, a trigger that operates between the closed and open positions of the slide.

In addition, four bolts each having a 90 ° spherical angle are provided on the camera body side to form a rotatable shaft on two opposite sides of the magazine housing side in order to realize a blocking portion having a simple but excellent effect in construction. It is provided. At this time, it is preferable to allow the shaft to rotate between two rotationally elastically fixed position using a spring, so that the film magazine can be accurately attached to the camera body when the film magazine is inserted, when the film magazine is removed The film magazine can be easily removed from the camera body.

In addition, the electrical contact portion on the film magazine side is preferably formed of six contact rivets installed at about 90 ° spherical angle position, and the corresponding camera side is provided with one end of leaf springs corresponding to the contact rivets. Form.

In addition, in the present invention, it is possible to install an adapter for mounting the film magazine to the camera housing.

Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention.

In the accompanying drawings, FIG. 1 is a plan view of a film magazine, FIG. 2 is a rear view of the film magazine according to FIG. 1, and FIG. 3 is a view corresponding to FIG. 1, which shows the internal structure of the film magazine as a hidden line. 4 is a rear view of the camera body for mounting the film magazine.

1 to 3 are diagrams showing the film magazine 1 of the present invention which can be attached to the back of the camera body 2 shown in FIG. The camera body 2 shown in the figure can also be considered a camera housing as a connectable adapter. The rear surface of the camera body 2 is provided with a rectangular insertion opening (3) for accommodating the insertion aid (5) mounted on the magazine housing (4).

The insertion opening 3 and the auxiliary portion 5 between the camera and the magazine are formed in a rotationally symmetrical direction with respect to the blocking portion and the electrical disconnection portion. The blocking part is provided on the magazine side so that the shaft 6 (see FIG. 1) is rotatably provided on two opposite surfaces of the frame housing 4, which shaft is elastically supported by two springs. Can rotate between positions. At the positions of the cameras corresponding to the two shafts 6, two bolts 7, 7 'are provided which are spaced apart from each other at about 90 ° spherical angles. 1 and 3 are plan views of the film magazine showing the positions of the springs for fixing the shaft 6 and the shafts 6 provided on the top and center of the insertion aid 5. When inserting the insertion aid 5 into the insertion opening 3 of the camera body, two bolts 7 and 7 'facing each other in the rectangular insertion opening 3 slide into the inlet of the shaft 6. Is inserted. Subsequently, when the insertion aid 5 of the film magazine 1 is continuously inserted, the spring-supported shaft 6 rotates to accommodate and support the bolts 7 and 7 'provided in the insertion hole 3 of the camera. Since the receiving support state of the bolts 7 and 7 'by the spring support shaft 6 of this film magazine is essential in the present invention, the film magazine 1 can be mounted to the camera body 2 without any supplementary operation. This is done automatically, and this release of the receiving support is again automatic by removing the film magazine completely from the camera.

On the film magazine side, the electrical weeding section is provided with six contact rivets 8, respectively, provided on the side of the insertion aid 5 (see FIG. 1) to one side of the 90 ° rotational position (see FIG. 2). 8 '), and on the corresponding camera side, it consists of six leaf springs 9 provided on each side of the rectangular insertion opening 3.

The insertion aid 5 of the film magazine 1 includes a rectangular picture gate 10, which is a horizontal size photographed in a horizontally laid state, and a vertical size in a vertical state. Used for shooting. The picture gate 10 can be closed closed by a slide 11 that is flexibly formed so as to bend, and can move between its closed position and the open position inside the magazine housing 4. Operation of the slide 11 inserted into the insertion opening 3 of the camera is achieved by externally operating a trigger 12 which rises outward from the magazine housing 4. 3 shows the slide 11 with the picture gate 10 open. When the trigger 12 is moved in the direction of the arrow 13 in this state, the slide 11 is moved above the picture gate 10 to close the inside of the magazine housing 4 so that light does not pass through.

The internal structure of the film magazine 1 is shown in FIG. As shown in this figure, inside the film magazine 1, a winding reel 15 and a film spool 14 which are driven and driven by an intermediate wheel 17 from a drive motor 16 are provided. . The film wound on the film spool 14 moves into a film rail held by a film slide rail and a film support plate not shown in the drawing.

As can be seen in FIG. 1, the film magazine 1 of the present invention is selectively mounted on the camera body 2 from two positions of 90 ° rotation for selective shooting of the horizontal size or the vertical size without rotating the camera body. Can be attached.

The wall 4a is pivotally mounted in the magazine housing 4, and this wall 4a can be flipped downward. In addition, the trigger 12 is operated externally for the operation of the slide 11.
