Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a battery box for equipment such as a camera and a video device that uses a plurality of batteries such as a main battery and a backup battery.

[Conventional technology]

Conventionally, generally in the battery box of this kind of equipment,
Each battery was stored in its own dedicated battery compartment.

Therefore, we will put multiple batteries in the same battery room,
If the lid has the smallest size that allows the largest one of the batteries to be taken in and out, only one lid is required. Further, if the partition or locking member for each battery is not necessary, the batteries are closely arranged side by side. Since the battery can be accommodated in it, the internal space becomes smaller.

In addition, it is desirable that the inside of the battery is waterproof, and a battery box that has an advantage in terms of the number of parts if a waterproof structure is used has been proposed in recent years.

[Problems to be Solved by the Invention] However, in the battery box as described above,
Since you can only remove and install batteries one by one, after removing all the batteries, if you put the batteries in the wrong order, you will not be able to install the batteries that should be installed, or you will forget to install them. There was a flaw. For example, if a battery that has been forgotten to be installed is used as a power source for backing up data in the camera or as a power source for liquid crystal display, if the battery for the main power source is also installed, shooting and recording operation by the camera Since it is often possible, there is a problem in that, after photographing, the data or the like to be recorded in the recording medium together with the photographed image is not recorded in the recording medium together with the photographed image.

The present invention has been made to solve the above-mentioned conventional problems, and provides a battery box that can wipe out forgetting to insert a battery and prevent malfunctions due to forgetting to insert a battery such as data recording error. Has an aim.

[Means for solving problems]

The battery box according to the present invention has a battery chamber capable of storing a plurality of batteries, and a second battery of the plurality of batteries housed in the battery chamber is discharged as the first battery is discharged. A battery mounting restriction mechanism is provided which prevents the mounting of the second battery in the storage portion and allows the mounting of the second battery in the storage portion of the second battery when the first battery is mounted. Is.

[Action]

In the battery box of the present invention, for example, when there is a first battery and a second battery, the battery mounting restriction member causes the second battery in the storage portion of the second battery to be discharged as the first battery is discharged. The mounting of the second battery is prevented, and the second battery can be mounted in the storage portion of the second battery along with the mounting of the first battery, thereby preventing forgetting to mount the first battery. You can

〔Example〕

 An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1 showing a vertical cross section of a battery chamber 6 accommodating each battery, reference numeral 1 denotes a main battery accommodated in a main battery chamber 61, which compresses a conical coil spring 7 attached to a back wall. . 2 is a backup battery stored by inserting the L-shaped lever 4 in the clockwise direction into the backup battery chamber 62, and 3
Is rotatably supported by the housing 8 so as to shield a part of the backup battery chamber 62 and the main battery chamber 61 from the external environment.
It is a battery lid which is hooked at 8 m and prevents the main battery 1 from being pushed out by the repulsive force of the conical coil spring 7.

In addition, the L-shaped lever 4 is provided with a push-out portion 41p and a blocking portion 42s by bending the tips of both arm portions 41 and 42 formed in a mountain shape inward, and the center is located at a required position of the housing 8. Fixed fixed shaft
It is rotatably supported by 4j and is urged in the counterclockwise direction by a tension coil spring 4b held between the arm portion 41 and the housing 8.

A latch lever 5 is rotatably supported by a fixed shaft 5j and is urged in a counterclockwise direction by a tension coil spring 5b, and a hook 5k at the tip is bent to the outside of the arm 41. By latching the latching piece 41k formed as described above, the L-shaped lever 4 is placed in a posture in which the backup battery 2 inserted between the pushing portion 41p and the blocking portion 42s is sandwiched.

Note that FIG. 3 is a perspective view of the main battery 1 and the backup battery 2 in the storage state, and reference numerals 21 and 22 are contact pieces that are attached to the housing 8 and are in pressure contact with the end surface and the side surface of the battery 2. .

The battery lid 3 is constructed by assembling an inner lid 32 to an outer lid 31 as shown in the diffusion diagram of FIG.

The outer lid 31 is formed by integrally forming a main body 31B and a spring portion 31S via a thinly bendable hinge portion 31H, and fits in a retaining groove 8m of the housing 8 at the center of the tip of the main body 31B. A claw 31t is projected and a dowel 31d is projected in the center of the inner surface (upper surface in the figure), and a pair of mounting seats 31z having screw holes are arranged on both sides of the dowel 31d on the coaxial line including the dowel 31d and the claw 31t. It is set up.

The inner lid 32 is a flat plate that is substantially the same in shape and size as the main body 31B of the outer lid 31, has a recess 32h that is largely carved in the center of the inner surface, and has a pair of ears 32e at the tip end side. Square hole 32a
And a pair of stepped oval holes 32c are engraved at a position facing the dowel 31d, and the inner lid 32 is provided with an outer lid 31
When they are superposed on each other, the retaining screw 33 is screwed into the mounting seat 31z to be reciprocally slidably assembled in the axial direction.

In addition, an Ω-shaped elastic body 34, which is attached by fitting an ear 34e to an ear portion 32e, is attached to the square hole 32a, and the inner lid 32 is urged toward the tip of the outer lid 31 by the dowel 31d. is doing.

In addition, 35 is a waterproof packing, which is fitted in a groove 32m formed around the inner lid 32, and 36 is a recess 32h.
The lid is fitted with double-sided tape or the like to prevent water from entering through the square hole 32a and the oval hole 32c.

The operation of the above configuration will be described with reference to FIGS. 4 to 6.

In FIG. 4, the outer lid 31 is moved in the direction of the arrow a by compressing the spring portion 3S, and the claw 31t is disengaged from the retaining groove 8m of the housing 8. However, since the inner lid 32 is in the battery chamber 6 and maintains the waterproof posture, the outer lid 31 is displaced with respect to the inner lid 31.

Therefore, the battery lid 3 which receives the pushing force of the main battery 1 urged downward by the conical coil spring 7 has a hinge portion.
The main battery 1 can be taken out by rotating in the direction of arrow b around 31H as shown in FIG. Inner lid 32
Is always urged toward the claw 31t side by the elastic body 34 via the dowel 31d, so that after the opening of the battery lid 3, it returns to its original fixed position and does not dangle.

Then, the latch lever 5 is moved to the arrow c by an operating member (not shown).
When the hook portion 5k is disengaged from the hooking piece 41k, the L-shaped lever 4 is rotated in the direction of the arrow d by receiving the storage force of the tension coil spring 4b. 2 is pushed out into the main battery chamber 61, so that it can be easily taken out. At this time, as shown in FIG.
Since the blocking portion 42s of the L-shaped lever 4 is in the posture of protruding into the main battery chamber 61, it is impossible to insert the main battery 1 in this state.

Therefore, when the battery is to be stored next, the backup battery 2 is first exposed to the battery chamber 62 and then pushed in, so that the battery 2 comes into contact with the push-out portion 41p of the L-shaped lever 4 and the battery is pushed by the arrow d. Since it rotates in the opposite direction, when it is hooked by the hooking lever 5, the contact pieces 21, 2 are placed at a fixed position in the backup battery chamber 62.
It is pressed against 2 and stored.
The main battery 1 can be inserted because the main battery 1 is retracted.

[Effect of device]

As described above, according to the present invention, the mounting restriction member prevents the mounting of the second battery in the storage portion of the second battery unless the first battery is mounted.
Since the first battery and the second battery must be mounted one by one, and the second battery must be mounted after the first battery has been mounted, the first battery should not be mounted. An effect that it is possible to prevent a data recording error and the like due to forgetting to install the first battery is obtained.
