Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improvement in a cartridge loading device for a camera.

As shown in FIG. 7, the conventional camera cartridge loading device has a structure in which the lower side of the cartridge chamber of the main body 20 is cut out and a protrusion 22' is provided on the lower side of the back cover 22. Patrone 2
3 is inserted and removed from the bottom of the main body 20 in the direction of arrow a, using the rewinding gear 2 provided on the upper side of the cartridge chamber.
There is one in which the cartridge 23 is engaged with a fork 21 having a fork 1', and when the back cover 22 is closed, the lower part of the cartridge 23 is pushed up and supported by the protrusion 22' to regulate its position.

However, with this type of configuration, it becomes impossible to utilize the space in the lower part of the cartridge chamber where the above-mentioned notch is provided, so this is a drawback that is a major constraint for cameras that need to effectively use a small amount of space. It was hot.

Further, this type of structure has the disadvantage that the cartridge tends to fall out of the notch, making it extremely difficult to handle.

FIG. 8 shows another example of a conventional cartridge loading device, in which a rewind gear 34 and a fork 33 inside the rewind gear 34 are installed in a through hole in the lower side of the cartridge chamber of the main body 30.
The fork 33 is coupled to the rewinding gear 34 so that it can move up and down and rotate integrally with the rewind gear 34, and the fork cover 32 that covers both of them and the fork 33 are A spring 35 for pushing up the fork is inserted into the fork cover 3, and the knob 33' at the other end of the fork 33 is inserted into the fork cover 3.
2, and the cartridge 36 can be inserted or removed by pulling down the knob 33', pulling out the fork 33 downwards, inserting or removing the cartridge 36 into the cartridge chamber from direction b, and regulating its position with the upper and lower inner walls of the main body 30. I try to do this.

However, this type of configuration has the disadvantage that the mechanism becomes complicated and costs increase.

The present invention has been made in view of the above circumstances, and
A space for loading a cartridge in which a finger can be inserted between the film feeding fork and the cartridge being loaded on the opposite side of the film feeding fork. a cartridge chamber configured to form a cartridge; a cartridge loading lid for opening and closing the cartridge chamber; This camera cartridge is equipped with a cartridge position regulating member that is inserted into a cavity to regulate the position of the loaded cartridge, and has a simple configuration and can reduce costs, as well as making effective use of space and offering excellent operability. The purpose is to provide a loading device.

Embodiments of the present invention will be described based on the drawings. First, FIG. 1 is a layout diagram of each component in a camera embodying the present invention, and 1 is a camera body, 2 is a viewfinder, 3 is an aperture, 4 is a spool chamber, 5 is a spool, and 6 is a spool chamber. A battery compartment, 7 a film winding and rewinding mechanism, 8 an electronic flash device, 9 a cartridge compartment, and 10 a fork.

Figures 2 to 5 show the cartridge chamber of the camera in Figure 1. Figure 2 is a longitudinal sectional view of the cartridge chamber, showing the cartridge loaded state, and the third
4 and 4 are explanatory views of the cartridge taken out, and FIG. 5 is an exploded view of the fork portion.

In Fig. 2, numeral 11 is a front cover, from the bottom of which a fork guide rod 11a protrudes toward the cartridge chamber side, and 12 is a main body, the upper part of which is the cartridge 14 loaded on the upper wall side of the cartridge chamber. The taper 12a is tapered to form a gap in which a finger can be inserted between the guide rod 11a, and a through hole is provided on the lower wall side of the taper 12a, and a fork is inserted into the through hole with the guide rod 11a as the center. 10 and a fork rotation rewinding gear 15 are coaxially fitted. As shown in FIG. 5, the fork 10 and the gear 15 are such that a projection 15a provided inside the gear 15 engages with a groove 10a on the outer periphery of the fork 10, and the fork 10 is connected to the gear 1.
5, the groove 10a is centered around the guide rod 11a.
It is movable up and down along the fork 1 and is integrally rotatably connected to the gear 15, and is connected to the fork 1 by a spring 16 interposed between the bottom surface of the front cover 11
0 is pushed upwards. Also, fork 10
A collar portion 10b that comes into contact with the gear 15 is provided at the bottom of the
is provided. On the other hand, the back cover 13 is provided with a protrusion 13a on the upper side as a cartridge position regulating member,
When the back cover 13 is closed, the protrusion 13a fits into a gap formed in the upper part of the cartridge 14. Also, 14a is patrone 14
This is a protrusion for engaging a fork provided on the shaft end of the fork.

With the above configuration, when the cartridge is loaded in a photographable state as shown in FIG.
4, front and back play is restricted by the main body 12 and back cover 13, and vertical play is suppressed by the lower surface of the main body 12 and the protrusion 13a of the back cover 13. In this state, the film is wound and rewound.

Next, when taking out the cartridge, open the back cover 13 as shown in FIG. is hooked onto the upper part of the cartridge 14, and the cartridge 14 can be easily taken out along the taper 12a of the main body 12.

In addition, when loading the cartridge, you can do it in the reverse order to the above, but when inserting the cartridge 14, make sure that the protrusion 14a of the cartridge 14 does not hit the fork 10 and interfere with inserting the cartridge.
The fork 10 is lowered against the spring 16 and the cartridge 14 is loaded.

FIG. 6 shows another embodiment of the cartridge chamber configuration. When the height of the upper portion of the cartridge chamber is low, that is, when the space above the camera is not required, the upper wall portion of the main body 12' may be removed. The upper surface of the front cover 11' is used instead of the main body, and a gap is formed between the upper surface of the front cover 11' and the cartridge 14', and the back cover 1 is inserted into the gap.
The protrusion 13'a of the cartridge 3' is fitted into the cartridge, and the means for loading the cartridge into the camera and regulating the position are the same as in the above embodiment.

As explained above, according to the present invention, it is possible to provide a camera cartridge loading device that has a simple configuration, can reduce costs, can effectively utilize space, and has extremely good operability, and its effectiveness is extremely high. It's expensive.
