b. A cylindrical portion 1a for positioning the grip 1 on the camera body 7 is provided above the battery chamber ceiling 1b. The grip 1 needs to be formed so as not to make a large gap with the camera body in order to prevent water or the like from entering the battery chamber 1e.

As shown in FIG. 10, the camera body 7 is provided with a movable switch lid 8 which is adjacent to the grip 1 and covers a switch (not shown). In order to cover the gap, a waterproof wall 1f is provided continuously with the grip outer peripheral surface portion 1h.
Therefore, when the battery 3 is taken out of the battery chamber 1e, it is impossible to operate the battery 3 from the side of the grip 1. Therefore, a cutout portion 1c is provided in a part of the battery chamber ceiling 1b. The end surface 3b of the battery 3 exposed in the cutout portion 1c is operated by placing a finger on it.

[0005]

However, the end surface 3b of the battery 3 has no unevenness, and the contact terminal 4a,
4b receives the biasing force of the battery 3 from the finger and the end surface 3
It was very difficult to pull out from the battery chamber 1e only by the frictional force with b.

[0006] Therefore, an object of the present invention is to provide an electric device constructed so that a battery can be taken out surely.

[0007]

In order to achieve the above object, in the present invention, a contact which is rotatably provided on an end surface of the battery housing portion and contacts a part of a battery housed in the battery housing portion. By having the battery discharge member in which the part is formed, the stored battery can be easily discharged.

[0008]

1 is a perspective view showing a state in which a battery discharging member 2 of the present invention is attached to a grip 1 of a camera having a battery chamber described in the conventional example, and FIG. 2 shows a shape of the battery discharging member 2. FIG. 3 is a top view of the grip showing a state in which a battery is loaded in the battery chamber.

The battery discharging member 2 is made of a relatively elastic material such as polyacetal resin, and as shown in FIG. 2, a protrusion 2a which is a contacting part for contacting the battery and a substantially conical operating part 2e. And knurl 2b, annular locking portion 2
c and the plate-like locking portion 2e are integrally formed. The battery discharging member 2 is engaged so that the annular locking portion 2c holds the cylindrical portion 1a formed on the upper portion of the battery chamber ceiling 1b of the grip 1, and further the tip of the plate-shaped locking portion 2e. The boss portion 2d provided on the battery chamber ceiling 1b is located at the center of the cylindrical portion 1a and is fitted into the hole portion 1d provided on the battery chamber ceiling 1b from the lower surface of the battery chamber ceiling 1b. Mounted rotatably.

FIG. 7 is a view showing the height relationship between the battery discharging member 2 and the battery when the grip 1 is viewed from the rear side of the camera. The protrusion 2a projects into the battery chamber 1e and the battery 3 It has been shown to be engageable.

When the battery is loaded, the battery discharging member 2 rotates counterclockwise when the protrusion 2a is pushed by the battery 3, and FIG.
The state becomes as shown in. At this time, the operation portion 2e is arranged along the edge of the cutout portion 1c of the battery chamber ceiling so that a finger can easily enter.

Next, the discharging operation of the battery by the battery discharging member 2 will be described. FIG. 5 is a cross-sectional view of the grip 1 showing the movements of the protrusion 2a and the battery 3 during the discharging operation.

When the battery discharging member 2 is rotated clockwise by placing a finger on the operating portion 2e, the protrusion 2a pushes the concave portion 3a of the battery 3. The battery 3 moves in the battery chamber 1e.
Since it is limited to the inner wall of No. 3, not only the rotation operation but also the downward movement as seen in FIG. 5 is performed along the inner wall, but the force F1 from the protrusion 2a is not the same as the inclination of the concave surface 3a. In relation, it acts in a direction that does not hinder the downward movement.

FIG. 4 shows a state in which the battery discharging member 2 has finished the battery discharging operation. The battery discharging member 2 has a stopper portion (not shown) on the end surface of the battery chamber ceiling 1b. The rotation of the protrusion is stopped, and the protrusion comes to the position 2a '. In this state, the battery chamber 1
It is possible to take out the battery 3 by directly grasping the outer peripheral surface of the battery 3 exposed from e with a finger.

Next, the operation of taking out the battery from the above state will be described. FIG. 6 shows the battery in the battery chamber 1e.
It shows the movement of the battery discharge member 2 (projection portion 2a) when further taken out.

When the battery is taken out while rotating it in the direction shown by the arrow, the battery discharging member 2 has the protrusion 2
a is pushed by the outer peripheral surface of the battery 3 and rotates clockwise, and normally the protrusion 2a does not hinder the removal of the battery.

However, at the time when the protrusion 2a is at the position 2a ', the force F2 exerted by the battery 3 on the protrusion 2a is a slight amount due to the inclination of the outer peripheral surface of the battery 3, but the protrusion 2a. In some cases, the protrusion 2a acts in a direction in which the battery 2a is not rotated to the right, and the protrusion 2a interferes with the battery take-out operation. Therefore, the above problem is solved as follows. As described above, the battery discharging member 2 is formed of an elastic material, and the battery discharging member 2 is not pressed by the finger during the battery removing operation unlike the discharging operation described above. It is possible to bend to. Therefore, if the overlap amount t between the protrusion 2a and the battery 3 shown in FIG. 7 is set within a range in which the battery discharging member 2 is flexible, the protrusion 2a will pass over the battery 3 and It can be taken out.

[0018]

As described above, the present invention has the battery discharging member which is rotatably provided on the end face of the battery housing and has the contact portion which comes into contact with a part of the battery housed in the battery housing. As a result, the battery discharging member having excellent operability can be provided in a small space of the battery housing portion, and the battery housed in the housing portion can be reliably and easily taken out.
