DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates includes a simple camera function, turtle unexposed film is loaded in advance
The present invention relates to a battery contact piece of La.

[0002]

2. Description of the Related Art A camera in which an unexposed film is loaded in advance is used.
As is well known, Mera is a film-integrated camera that allows users to easily enjoy photography, and is used mainly when purchased and used on the go, such as during travel. . In response to this request, the compact Konica MiNi has been marketed and is well received.

[0003]

Although it is desired to make the camera more compact than the market, since the basic functions of the camera do not change, compactness has reached a certain limit. In such a state, the unexposed film is loaded in advance.
The space occupied by the battery in the installed camera components is very large. Therefore, by reducing the space in the battery compartment, the unexposed film can be loaded in advance.
It is an object of the present invention to contribute to downsizing of a camera .

[0004]

According to the present invention, an unexposed film using a cylindrical battery is loaded in advance.
Camera , the positive electrode and the position around the positive electrode
And the shoulder connected to the positive electrode via the step is the same.
While using a cylindrical battery composed of members,
The shape of the battery contact piece for the positive electrode should be
Then, the positive electrode of the cylindrical dry battery is connected to the two battery contact pieces for the positive electrode.
Positioned between forked parts, forked part
When the minute part comes in contact with the shoulder, the electric potential with the positive electrode of the cylindrical
The connection is made so as to perform a pneumatic connection.
Are those exposed film is solved by a camera is loaded, when disposed batteries in longitudinal advance unexposed Fi
The height direction of the camera on which the lum is loaded is reduced.

[0005]

FIG. 1 shows an unexposed film according to the present invention.
This is a view showing the external appearance of the camera , which is loaded with 135 film in advance, and after shooting is sent to the lab with the film stored inside without rewinding, developing and printing Is performed.

A turtle previously loaded with an unexposed film
The unexposed film used in the cartridge is loaded in the patrone, and after being made light-tight, the winding shaft on the film winding chamber side is driven to take up all the film in the patrone. Wind up the room. The user winds the film every time a photograph is taken, so that the photographed film is wound into the patrone. Therefore, in the lab, the photographed film can be taken out of the patrone in the light room.

Since the photographed film can be easily taken out by bending a part of the back cover, the function and appearance of the camera are inspected, and the back cover and defective members are replaced. If an unexposed film is loaded, it can be reused.

In this embodiment, an unexposed film is loaded in advance.
Cartridge loaded in to which the camera is different from the commercially available cartridge (JIS K7528), outer diameter cartridge of 20.6mm is used. As a result, it is possible to make the thickness of the camera very thin except for the taking lens,
An ultra-thin compact camera has been realized.

In FIG. 1, 1 is a photographing lens, 2 is a viewfinder, 3 is a strobe light emission window, 4 is a strobe charge indicator lamp, 5 is a film counter, 6 is a release button, 7
Reference numeral 8 denotes a back cover, and reference numeral 8 denotes a cardboard carton on the outer surface of which a product name, a simple usage method, and the like are displayed.

FIG. 2 is a diagram of a conventional battery chamber.
(A) is a perspective view thereof, and FIG. 2 (b) is a longitudinal sectional view thereof. Normally, a single AA battery is used for a camera pre-loaded with an unexposed film in terms of performance, and the internal components are the largest in volume together with the strobe condenser. Also, since the dimensions of AA batteries are determined by JIS, they cannot be freely changed in design like other mechanical parts, and the configuration and dimensions of the battery chamber in which AA batteries are loaded are limited. Unexposed film is loaded beforehand
Directly affects the outer diameter of the camera . In the figure,
11 is a dry battery, 11a is a positive electrode, and 11b is a negative electrode. Reference numeral 12 denotes a contact piece for the positive electrode, and 13 denotes a contact piece for the negative electrode.
a, is in pressure contact with the negative electrode 11b. 14 is a side wall of a part of the battery compartment.

FIG. 3 is a view of a battery chamber according to an embodiment of the present invention. FIG. 3 (a) is a perspective view thereof, and FIG. 3 (b) is a longitudinal sectional view thereof. The shoulder 11c of the dry battery 11 has a positive electrode 11a and a positive electrode 11a.
The electrode is a positive electrode because it is positioned around the stepped portion a and is made of the same member as the positive electrode 11a . Reference numeral 22 denotes a contact piece for the positive electrode, which is configured to make electrical contact with a shoulder portion 11c of the dry battery 11 by a forked end portion 22a. Reference numeral 13 denotes a contact piece for the negative electrode, which is in pressure contact with the negative electrode 11b as in FIG. 24 is a part of the side wall of the battery compartment.

By constructing the positive electrode contact piece 22 in this manner, the shoulder 11c of the dry battery 11 and the side wall of the battery chamber in FIG.
Gap d between 24 since the gap becomes dimension of the height h of the positive electrode shorter than D of the shoulder portion 11c and the side wall 14 of the battery compartment of the battery 11 in FIG. 2, the dimensions of the battery compartment previously un can be shortened h min Exposure field
The overall outer dimensions of the camera on which the lum is loaded can be reduced by h.

The battery can be applied not only to AA batteries, but also to other types of batteries as long as the shoulder and the positive electrode are made of the same material.

In addition, it is desirable to provide an escape hole 24a in the side wall 24 of the battery chamber in consideration of variations in the height h of the positive electrode.

Further, both the positive electrode contact piece 22 and the negative electrode contact piece 13 may have elasticity, or either one of them may be used.

[0016]

As described above, according to the present invention, the space on the positive electrode side can be reduced, and as a result, the space in the battery chamber is reduced, and the unexposed film is loaded in advance.
Since the outer diameter of the camera can be reduced, it is possible to realize a camera which has better portability and is loaded with an unexposed film in advance .
