Abstract

PURPOSE: To prevent a battery from being fallen off by mounting a camcorder and not releasing the battery only with the operation of an operation knob. CONSTITUTION: The battery is fixed by an operation knob 1 moved in the direction of the arrow A, a lock member 7 interlocking with the knob 1, a coil spring 6 restoring them to their home position, a retainer 8 and fastening machine screw 9 in a slidable way. When the operation knob 1 is moved to an end, since the battery 2 is engaged by the lock member 7 with a very small amount of latch, the battery is not released. The battery 2 is easily and safely released by extracting it by a hand in this state.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a battery attaching / detaching device for a camera-integrated magnetic recording / reproducing device.

[0002]

2. Description of the Related Art A conventional battery attaching / detaching device will be described below with reference to the drawings.

FIG. 5 shows a conventional battery mounting device, (a) is a rear view thereof, and (b) is a side sectional view thereof. The battery 2 has an upper claw 21 and a lower claw 22 formed on the battery 2 and an upper claw 4 formed on the operation knob 1.
And the lower claw portion 5 formed on the main body device 11,
Is held.

When the operating knob 1 is moved in the direction A in the figure, the upper claw portion 4 is separated from the upper claw 21 of the battery 2, and is moved in the direction of arrow B by the spring restoring force of the battery terminal 3 to move the main body device. It is released from 11.

[0005]

However, in the above structure, since the battery 2 is pushed out by the spring restoring force of the battery terminal 3, the battery 2 rotates about the lower fixed claw 5 as a fulcrum and drops in the direction of arrow B. , The user's safety may be impaired, and the battery 2 may be damaged.

The present invention solves the above problems and provides a battery attachment / detachment device which does not release the battery only by moving the operation knob and allows safe and easy removal.

[0007]

In order to solve the above-mentioned problems,
The battery attaching / detaching device of the present invention has a structure for preventing the battery from being released only by moving the operation knob.

[0008]

According to the present invention, due to the above-mentioned structure, the battery does not drop off only by moving the operation knob, and safe and easy removal is possible.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a battery attaching / detaching device of the present invention will be described below with reference to the drawings.

FIG. 1 shows a camera-integrated magnetic recording / reproducing apparatus equipped with the battery attaching / detaching device of the present invention. In the figure, the same components as those in FIG. 5 are designated by the same reference numerals and the description thereof will be omitted.

A major feature of the configuration of this embodiment is that the operation knob 1 and the upper claw 4 which are conventionally formed integrally are configured as separate parts. However, the operation knob 1 and the upper pawl 4 formed on the lock member 7 can be interlocked with each other because the interlocking pawl 12 and the recess 19 are engaged with each other.

FIG. 2 is an exploded perspective view showing a schematic structure of the battery attaching / detaching device of the present invention. The first through hole portion 14 of the lock member 7 in which the upper side claw 4 is formed is inserted into the screw receiving portion 13 formed in the main body device 11 from the arrow D direction, and the coil spring 6 is inserted into the spring receiving portion 15 in the arrow E direction. Then, the pressing plate 8 is attached to the coil spring 6 by the spring pressing portion 16 formed on the pressing plate 8.
While compressing the end face of, the screw receiving portion 13 formed in the main body device 11 and the second through hole portion 17 formed in the holding plate 8 are fastened with the stopper screw 9 via the lock member 7. The operation knob 1 inserts the screw receiver 18 into the third through hole 21 formed in the main body device 11 from the direction of the arrow F so that the interlocking claw 12 engages with the recess 19 formed in the lock member 7. Then
Tighten with the operation knob stop screw 10.

The operation of the battery attaching / detaching device constructed as above will be described below with reference to FIGS. 3 (a) to 3 (c) and FIG.
This will be described with reference to (a) to (c).

First, FIG. 3A is a perspective view of a main part showing a state before the operation knob 1 is moved. Due to the restoring force of the coil spring 6, the lock member 7 and the operation knob 1 interlocked with the lock member 7 are pressed against each other in the arrow G direction.

FIG. 3B is a perspective view of the main parts showing the operation of each part when the battery 2 is mounted. Battery 2 with arrow H
When inserted in the direction, the slope of the upper claw portion 4 formed on the lock member 7 is pushed, and the lock member 7 moves in the arrow J direction while compressing the coil spring 6. After that, coil spring 6
The lock member 7 is returned to the original position by the return force of.

FIG. 3 (c) is a perspective view of essential parts showing a state after the battery 2 is mounted. In the figure, L indicates the amount of engagement of the upper claw portion 4 formed on the lock member 7 and the upper claw 22 formed on the battery 2.

Next, the operation when the battery 2 is released will be described. FIG. 4A is a perspective view of a main part when the operation knob 1 is moved. When the operation knob 1 is moved in the direction A to a movement end (not shown) by the movement amount S, the lock member 7 is also moved by the movement amount S in association with it. FIG. 4B is a cross-sectional view of the main parts when the lock member 7 moves in the direction of arrow A with the movement amount S. At this time, the upper side claw portion 4 formed on the lock member 7
Is the upper claw 21 formed on the battery 2 and the amount of contact l
The battery 2 is not released because it is engaged with.

However, in FIG. 4A, the gap X between the interlocking claw 12 of the operation knob 1 and the concave portion 19 of the lock member 7, and the through hole portion 14 of the lock member 7 and the screw receiving portion 13 of the main body device 11 are shown. Because of the gap X, the lock member can move with the remaining movement amount X. Therefore, X is larger than the applied amount 1 in FIG. 4B, and the upper claw 2 of the battery 2 is
If the R dimension r of the tip R portion 23 of 2 is larger than the applied amount l, the upper claw portion 5 is moved by the tip R portion 23 in the G direction and released by loading the battery 2 in the C direction in this state. be able to.

[0019]

As described above, according to the present invention, the battery can be safely and easily taken out without releasing the battery only by moving the operation knob.
