Description

[Detailed description of the invention] a. Technical field This invention relates to an improved technology for a battery storage case for a camera.

b. Prior Art and Problems Recently, electronic cameras are increasingly using lithium batteries, which have a fast charging speed and a relatively long discharge time.
Because of the disparity in their popularity, there has been a desire for a so-called compatible camera battery storage case that can also use, for example, alkaline manganese batteries, which are popular especially overseas.

c. Purpose This invention was made in view of the above background, and the purpose is to provide a battery storage case for a camera that can compactly store either a lithium battery or an alkaline manganese battery as described above. It is said that

d. Structure of Embodiment Hereinafter, an embodiment of this invention will be described with reference to the accompanying drawings.

Figures 1 to 5 are diagrams showing one embodiment of this invention, respectively. Figure 1 is a longitudinal cross-sectional view of a state in which a lithium battery is housed, and Figure 2 is a longitudinal cross-sectional view of a state in which a AAA alkaline manganese battery is housed. Figure 3 is a back view with the outer cover removed, Figure 4 is a perspective view showing the arrangement of the main parts, and Figure 5 is when AAA alkaline manganese batteries are stored. FIG. 2 is a layout diagram of each battery.

In each figure, 1 is a camera body, and a battery storage case 2 according to the invention is provided at one end of the camera body.

This battery storage case 2 contains a lithium pack containing two lithium batteries with an open circuit voltage of 3V (output voltage 6V) and 3 or 4 AAA alkaline manganese batteries (1.5V each; 6V for 4 batteries). It is designed to be able to store 4.

5 is an outer lid of the battery storage case 2, and electrode contacts 6, 6 for alkaline manganese batteries are provided on the inner surface 5a of the outer lid.
It can be opened and closed with respect to the battery storage chamber 2a by a hinge mechanism 7.

Reference numerals 8 and 8 designate electrode terminal members, which are formed by bending a band-shaped conductive member having a width corresponding to the difference in total height between the lithium pack 3 and the alkaline manganese battery 4 in a single meandering S-shape.

The electrode terminal members 8, 8 are connected to the upper side of each lithium pack 3 when the lithium pack 3 is stored.
There are 8 electrode contacts at positions corresponding to electrodes 3a and 3b.
a, 8a, and is attached to the camera body 1 by a hinge mechanism 9 so as to be openable and closable inside the outer cover 5.

Reference numeral 10 designates electrode contacts for the alkaline manganese battery, each of which is made of a conductive spring member, and is provided at the bottom of the battery storage chamber 2a in a layout as shown in the figure.

e Effects of the Embodiment According to the battery storage case 2 configured as described above, when storing the alkaline manganese battery 4 which is longer than the total height of the lithium pack 3, the outer cover 5
After the outer cover 5 is opened and the four batteries 4 are housed with the polarities as shown in FIG. 5, passing through each curved part of the S-shaped electrode terminal members 8, 8, the outer cover 5 is closed.

In this way, the four batteries 4 are held by the electrode terminal members 8, 8, and their respective electrodes are connected to the electrode contacts 6, 6 on the outer cover 5 and the electrode contacts at the bottom of the battery storage chamber 2a. 10 and are electrically connected in series, making it possible to output 1.5V×4=6V.

Next, when storing the lithium pack 3 which has a short overall height, open the outer cover 5 and the electrode terminal members 8, 8 and insert the lithium pack 3 into the upper two electrodes 3a, 3b.
The electrode terminal members 8, 8 and the outer cover 5 are closed in this order.

In this way, the electrodes 3a and 3b of the lithium pack 3 come into contact with the electrode contacts 8a and 8a of the electrode terminal members 8 and 8, respectively, and an output of 6V can be extracted.

In the above embodiment, an example using S-shaped electrode terminal members 8, 8 was described, but the invention is not limited to this, and three or more curved portions may be used depending on the output voltage and the number of batteries. It may also have a meandering shape.

f Effects As described above, according to this invention, any of batteries having different total heights can be stored compactly.

Claims (1)

[Scope of utility model registration request] In a camera battery storage case configured to store batteries having different total height dimensions, a strip-shaped conductive member having a width corresponding to the difference in total height of the batteries is formed by bending the longitudinal direction of the strip in a serpentine shape. When storing a battery having a long total height, an electrode terminal member having electrode contacts at predetermined positions on the meandering side edge is attached so as to be openable and closable inside the outer cover of the case using a hinge mechanism. is housed in a manner that penetrates the curved portion of each part of the meandering electrode terminal member so that one electrode of the battery comes into contact with the electrode contact provided on the inner surface of the outer cover, and has a short total height dimension. A battery storage case for a camera, characterized in that when storing a battery, one electrode of the battery is brought into contact with an electrode contact of the meandering electrode terminal member.
