Abstract

PROBLEM TO BE SOLVED: To confirm information on unexposed film housed in a loaded cartridge for a camera capable of displaying information on film housed in the cartridge for a camera in a photographing state from the outside of a camera at any time by loading such a cartridge to a camera and visually confirming the information from the outside of the camera. SOLUTION: This camera is provided with a cartridge cover 12 equipped with a transparent window 20. The window 20 is attached and fixed to the aperture part of the cover 12 after it is engaged from the inner surface side. When the cover 12 is closed and locked with respect to the camera, the window 20 faces to a label L stuck to the cartridge P, and a bearing 20A is engaged with the shaft hole of the cartridge P. Then, a light shielding member 21 press- contacts with the periphery of the end of the cartridge P. Therefore, a user confirms the information on the loaded film from the outside of the camera through the window 20 at any time.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cartridge system for storing an unexposed film, for example, for APS or J.
The present invention relates to a 135 film film cartridge for a camera and a camera loaded with the film.

[0002]

2. Description of the Related Art For example, regarding a patrone for an APS camera, when the patrone is loaded into the camera, information on the sensitivity and the number of shots of the unexposed film to be stored is transmitted to the camera, and the exposure conditions at the time of shooting are transmitted. And the number of pictures that can be taken is automatically controlled.

Accordingly, a user can freely take a predetermined number of appropriately exposed photographs by a camera, regardless of the type or performance of the loaded unexposed film.

[0004]

However, in actual shooting, it is necessary to keep in mind the type of film and the number of shootable images. Such information may be forgotten when the camera is used in combination with the camera, and there is no means to know when the camera is borrowed from the owner.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and as a result, a camera patrone and a camera using the patrone can be used to check information on an unexposed film contained in the loaded patrone from outside the camera at any time. The purpose is to provide.

[0006]

An object of the present invention is to provide a camera patrone characterized in that information on a film to be stored in the camera patrone can be displayed on an end face of the camera patrone (the invention according to claim 1). And a camera patrone capable of displaying information on a film stored in the camera patrone is mounted on an end face of the camera patrone, so that the information can be visually recognized from outside the camera. Invention according to the present invention).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the first and second aspects of the present invention will be described with reference to FIGS.

[0008] camera shown as an embodiment a camera using an APS film, as shown in FIG. 1, for photographing the front lens L _S, viewfinder F, the power switch to the strobe light emitting portion S also not shown upper surface, A display panel and a shutter button are provided, and a tripod mounting screw hole T and a film loading unit 10 are provided on the bottom surface.

In loading the film into the camera, when the opening / closing knob 11 on the side is first operated, the patrone cover 12 on the bottom is unlocked and the cover supporting shaft 12A is supported by the function of the built-in elastic member. The camera is opened at an angle indicated by a dashed line, and the patrone room 13 of the camera is opened.

Next, the APS patrone P containing the unexposed film is inserted into the patrone chamber 13 from below, and the patrone cover 12 is closed. A signal relating to the film such as the number of films is input to the camera body, and at the same time, the film is sent out and the loading of the film is completed.

FIG. 2 shows a patrone for a camera according to the present invention.
For example, I relating to a film to be stored as shown in FIG.
A ring-shaped label L that specifically displays information such as the SO sensitivity and the number of films is attached, and the user checks the use state mark on the lower end face of the patrone beforehand if necessary, and then draws the label L. As shown in FIG. 2 (b), it can be arbitrarily attached coaxially to the lower end surface of the cartridge. The label L is affixed with a soft adhesive applied to the back surface so that the patrone P can be easily removed after the patrone P is taken out of the camera upon completion of the photographing.

It is to be noted that the label L specifically indicating the information on the film to be stored may be pasted or printed on the lower end face of the cartridge in advance. In this case, it is preferable that the printed sheet is pasted or printed so as to avoid the use state mark portion provided on the lower end face of the cartridge.

On the other hand, in the camera of the present invention, a patrone cover 12 having a transparent window 20 as shown in FIG. 3 is used. The transparent window 20 is a disk-shaped transparent body formed of an acrylic resin or the like, and has a central portion on which a bearing 20A of a patrone P is protruded, and a peripheral portion formed of a black elastic material such as, for example, maltoprene (trade name) material. A ring-shaped light shielding member 21 made of a material is integrated by bonding.

The transparent window 20 is provided with the patrone cover 1.
When the patrone cover 12 is closed and locked with respect to the camera, the transparent window 20 is attached to the patrone P when the patrone cover 12 is closed and locked with respect to the camera. The bearing 20A facing the label L
Is engaged with the shaft hole of the patrone P, and
1 is in a state of being pressed against the periphery of the end of the cartridge P.

Therefore, the user can check the information on the film loaded from the outside of the camera at any time through the transparent window 20, as shown in FIG. This is also effectively prevented by the light shielding member 21 described above. Also, as shown in FIG. 4B, the present invention can be applied to a camera having a patrone cover 12 on the upper surface of the camera.

Although this embodiment has been described only with respect to the APS patrone and the camera using the same, the present invention can be applied to many patrones and cameras including the J135 patrone and the camera using the same. It is.

[0017]

According to the first and second aspects of the present invention, specific information on the loaded film can be confirmed from the outside of the camera at any time, and a photograph can be taken with the type and performance of the film in mind. According to the third aspect, the bearing of the patrone is secured, and the smooth operation of feeding and rewinding the film is also ensured.
