BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic apparatus, and is suitably applied to, for example, a camera-integrated video tape recorder in which an external battery can be detachably attached to an apparatus main body.

[0003]

2. Description of the Related Art Conventionally, as this type of camera-integrated video tape recorder, there is a type which uses an externally mounted battery device detachable from a device main body as a driving power source. The camera-integrated video tape recorder can be carried and used by using the battery device, and can be used outdoors.

In FIGS. 10 and 11, reference numeral 1 denotes a battery mounting portion of a camera-integrated video tape recorder as a whole, which is provided, for example, at the rear of the apparatus main body.
The battery device 7 as shown in FIG. The battery mounting portion 1 is provided with a power supply contact piece 2 which obtains an elastic force by being arranged in a bowed shape. The battery device 7 is provided with a contact piece 8 at a position corresponding to the power supply contact piece 2 when attached to the main body. When the battery device 7 is mounted on the main body, the contact piece 8 and the power supply contact piece 2 come into contact with each other, and power is supplied to the main body from the battery device 7 via the contact piece 8 and the power supply contact piece 2 in order. Here, since the power supply contact piece 2 obtains an elastic force due to the shape of the power supply contact piece 2, the power supply contact piece 2 can sufficiently adhere to the contact piece 8, and poor contact can be prevented.

When the battery device 7 is mounted on the main body of the battery mounting portion 1, projections 3 and 4 are provided on the upper portion of the battery mounting portion 1 for holding the battery device 7, and the lower portion of the battery mounting portion 1 is held. Are provided with convex portions 5 and 6, respectively.
Further, at positions corresponding to the convex portions 3, 4, 5, and 6 of the battery device 7, the concave portions 9, 10, having substantially the same size as the convex portions.
11 and 12 are provided respectively.

In such a configuration, there are two types of mounting methods for mounting the battery device 7 on the battery mounting section 1 as described below. FIG. 13A shows the first method in which the same reference numerals are given to the portions corresponding to FIG. 10, FIG. 11, and FIG.

And 4 as a fulcrum. The second method is shown in FIG.
As shown in FIG. 13 (B) in which the same reference numerals are assigned to the same parts as in FIGS. 0, 11, and 12, the protrusions 3 and 4 provided below the battery mounting portion 1 are used as fulcrums. . Second
The method is only upside down from the first method, so only the first method is shown here.

In the battery mounting portion 1, the convex portions 3 and 4 provided on the upper portion are used as fulcrums, and the convex portions 5 and 6 provided on the lower portion are used as fixing portions. Convex portions 5 and 6 serving as fixed portions
The surface on the front side in the direction of attaching and detaching the battery device 7 is an inclined surface having a predetermined inclination angle, and is usually formed by the elastic force of a spring (not shown) connecting the projections 5 and 6 and the main body. Although it is in a protruding state, the structure is such that the force for pushing the battery device 7 in order to mount the battery device 7 is applied to the inclined surface so that the battery device 7 is pushed downward.

In such a configuration, the protrusions 3 and 4 serving as fulcrums are fitted into the recesses 9 and 10 of the battery device 7, and the position is used as a fulcrum.

Except for this, the configuration is the same as that of the battery mounting unit 1, and the battery device 7 shown in FIG. 3 is detachably mounted.

The fall prevention portion 21 is provided with claw-shaped protrusions 21A on both ends in the longitudinal direction of a plate-like member having elasticity such as plastic.
And 21B. Further, as shown in FIG. 4, the convex portions 21A and 21B are formed with inclined surfaces 21C and 21D, and have a mountain-like shape as a whole. When a force is applied to the inclined surfaces 21C and 21D of the convex portions 21A and 21B, the fall preventing portion 21 sinks downward as shown by a dashed line in FIG. As shown in FIG. 8, the whole is bent in a bow shape and deformed.
Further, as shown in FIG. 9, when the force is removed, the convex portions 21A and 21B are lifted upward as shown by the one-dot chain line in the figure, and return to the original shape. Thus, the fall prevention unit 2
1 is such that the convex portions 21A and 21B move up and down depending on the presence or absence of a force applied to the inclined surfaces 21C and 21D, so that the shape is deformed into an arc shape.

The elasticity of the fall prevention unit 21 is limited so that the fall prevention unit 21 does not bend unless a large force that the user pulls out is applied. In other words, the power contact piece 2 cannot push the protrusions 21A and 21B downward with an elastic force that pushes the battery device 7 down, and prevents the battery device 7 attached to the battery mounting portion 20 from falling off. obtain.
