Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention, which is also called a so-called disposable camera, relates to a simplified camera which is loaded with a preliminary film and which enables immediate photographing.

[0002]

[Prior Art]

 As is well known, the disposable camera is a camera with a pre-loaded film and is used only for shooting a single film. After the shooting of the built-in film, the film is sent to the photo lab with the film still loaded in the camera. Therefore, it is essential that the price of the camera be low.

[0003] On the other hand, in addition to the simple type camera for taking a standard size screen which has been commercially available in the past due to the diversification of shooting applications, a simple type camera having a different product series for wide-angle photography or panoramic photography, etc. As a result, the main body of the camera itself is becoming more diverse.

[0004]

[Problems to be solved by the device]

 Since increasing the variety of camera bodies will lead to an increase in the number of types of parts and a decrease in the efficiency of assembly work, the simple cameras of the wide-angle and panoramic photograph figures mentioned above should be replaced by conventional standard-size simplified cameras as much as possible. It is desirable to be able to share each component.

For example, it is not desirable to provide a simplified camera having different screen frames with different configurations.

As a result of solving this problem and improving the present invention, it is an object of the present invention to provide a simplified camera having a different product series by assembling an extremely simple member by an easy work at a low price. It is what

[0007]

[Means for Solving the Problems]

 The above-mentioned object is to provide a plurality of locking claws on the frame member in a simple camera that enables the configuration of a camera body having screen frames of different sizes by replacing the frame member forming the screen frame. This is achieved by a simplified camera characterized in that the frame member is fixed and integrated with the camera body by engaging the locking claw with the screen frame of the camera body.

[0008]

【Example】

 One embodiment of the present invention is shown in FIGS.

FIG. 1 shows the appearance of a simple camera, also called a single-use camera, containing a 35 mm film (J135). In the figure, 1 is a taking lens, 2 is a protecting member for the taking lens, 3 Is a finder, 4 is a shutter button, 5 is a film winding knob, and 6 is a film counter window.

In the camera, the camera body including the photographing lens 1, the shutter, the mechanical parts for film winding, and the film storage chamber is sandwiched by front and rear covers that also serve as exterior members to be integrated. It is composed by.

The camera is a standard size (24 × 36 mm) screen frame, and the wide-angle shooting lens 1 is attached to the camera, and the screen frame has a panorama screen size (13 × 36 mm). By inserting and engaging a frame member having a frame, and further by attaching a frame-shaped protective member to the periphery of the taking lens 1, it is commercialized and used as a simplified camera dedicated to panoramic photography.

When gripping both sides of the camera when taking a picture, the protective member 2 prevents the hands and fingers from blocking the angle of view of the taking lens 1, so that the camera is suitable for beginners who are unfamiliar. Therefore, it is possible to securely hold and securely take panoramic photographs with a wide angle of view in the horizontal direction.

FIG. 2 shows a main portion of the rear surface of the camera body 10, that is, the film transport surface side, 11 is a standard size (24 × 36 mm) screen frame directly formed on the camera body 10, and 12 is the above-mentioned. It is a light-shielding frame that is open on the front surface of a light-shielding cylinder that projects in front of the screen frame 11.

Reference numeral 13 is a film slide rail, 14 is a sprocket gear, 15 is a hoisting pawl integral with the film hoisting knob 5, and 16 is a patrone chamber accommodating a film winding patrone. After exposure, the film, one end of which is locked to the shaft of the cartridge, is sequentially wound into the cartridge by one frame by rotation of the winding upper claw 15.

FIG. 3 shows a panoramic screen frame member 20 inserted into and engaged with the screen frame 11, 21 is a pair of upper and lower shading plates forming a panoramic screen therebetween, and 22 is the above-mentioned A light-shielding frame corresponding to a panoramic screen, which is opened in front of a light-shielding cylinder in front of the light-shielding plate 21.

Further, 23 is a pair of upper and lower engaging claws protruding from the front surface of the light shielding tube, and 24 is a pair of small protrusions formed on the upper and lower side surfaces, respectively.

The frame member 20 is formed as a common member that is divided into upper and lower parts with the center of the screen frame as a boundary, as shown by the one-dot chain line in FIG. It is integrated as follows.

The frame member 20 is attached to the camera body 10 as shown in FIG.

FIG. 4 is a sectional view taken along the arrows AA and BB in FIGS. 2 and 3, in which the frame member 20 is inserted into the screen frame 11 of the camera body 10 and strongly pressed. At the position where the front surface of the light-shielding cylinder abuts on the camera body 10, the locking claw 23 elastically deforms by the slope 12A and engages with the light-shielding frame 12, and at the same time, the small projection 24 of the light-shielding cylinder on the camera body 10 The light shielding plate 21 is lightly press-fitted inside and the light shielding plate 21 is set at the same position as the screen frame 11 of the camera body 10.

Therefore, the camera body 10 is switched from the standard size screen frame to the panoramic size screen frame, and at the same time, the size of the light shielding frame in front of it is also switched in response to the change of the screen frame.

Further, as is apparent from the figure, the frame member 20 can be removed from the camera body 10 extremely easily by bending the locking claw 23 inward, so that the camera body 10 switched to the panorama can be re-installed. It is also possible to return to the standard camera body.

In the present embodiment, the frame member 20 and the panoramic screen are limited to the description, but the present invention is not limited to this, and for all screens smaller than the standard size such as a half size. It can be applied to other cameras.

[0023]

[Effect of the device]

 With the present invention, a simple camera that composes a standard size screen can be converted to a simplified camera that composes images of different sizes for panoramic photography, etc., by performing extremely simple assembly follow-up work without increasing the types of parts. As a result, it is possible to easily realize a wide variety of products based on standard assembly work, and it is possible to provide a wide variety of simplified cameras that can be used for a variety of purposes at a low price. It was
