Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technical field of a battery insertion mechanism for accommodating a dry battery for supplying power to the electronic device, particularly in a portable electronic device, in an outer casing of the electronic device. Belong.

[0002]

2. Description of the Related Art Conventionally, electronic devices such as radios, tape recorders, video tape recorders, disk recorders (players) and the like, in particular, portable electronic devices, use a dry battery for supplying power to the electronic devices. The electronic device is configured to be stored in an outer housing. That is,
As shown in FIG. 6, the outer housing of such an electronic device has an opening 101
1 has a built-in battery housing 102. The inside of the battery housing 102 is open to the outside through the opening 101. The opening 101 can be opened and closed by a removable lid member 103. That is, the lid member 103 is detachable from the rear surface of the outer housing 104, and forms a part of the rear surface of the outer housing 104 when the opening 101 is closed.

[0003] The battery housing 102 is configured to be able to store a predetermined number of dry batteries. In the battery housing 102, a section member 105 that is in contact with an electrode portion of a dry battery housed in the battery housing 102 is provided. The section member 105 is formed of a coil spring-like elastic material, and when a dry battery is stored in the battery housing 102, the cut member 105 comes into contact with the electrode of the dry battery. The section member 105 is connected to a power input unit of the electronic device in the outer housing 104. That is, this section member 1
05, when dry batteries are stored in the battery storage housing 102,
The electrode section of the dry battery is connected to the power input section of the electronic device, so that the dry battery can supply power to the electronic device.

[0004] Insertion of a dry battery into the battery housing 102 and removal of the dry battery from the battery housing 102 are performed by removing the lid member 103 from the outer housing 104 and opening the opening 101. This is performed through the opening 101. When the electronic device is used, the cover member 103 with the dry battery stored in the battery housing 102 is used.
Is attached to the outer casing 104, and the opening 101 is closed.

[0005]

By the way, in an electronic apparatus having the above-described battery housing 102, when the opening 101 is opened, the battery housing 10 is closed.
2 is open to the rear side of the outer housing 104. Therefore, the operation of inserting the dry battery into the battery housing 102 and removing the dry battery from the battery housing 102 is performed with the back of the outer housing 104 facing upward, that is, the outer housing 104 is moved forward. It is difficult unless the front part of the outer housing 104 is set to a state in which the front part is turned down.

Also, the operation of inserting a dry battery into the battery housing 102 and removing the dry battery from the battery housing 102 must be performed while the section member is elastically displaced through the dry battery, which is complicated. And it is difficult. When the elastic force of the section member 105 is increased to ensure the contact of the section member 105 with the electrode section, it becomes more difficult to displace the section member 105.

In particular, when a plurality of dry batteries are stored in series in the battery housing 102, not only the contact between the cut member 105 and the electrode portion but also the plurality of dry batteries In order to ensure the contact between the electrode portions, a material having a strong elastic force is used.
In this case, it becomes more difficult to displace the section member 105, and it becomes considerably difficult to insert the dry battery into the battery housing 102 and take out the dry battery from the battery housing 102.

Further, in the above-described electronic apparatus, the lid member 10 is inserted during the operation of inserting and removing the dry battery.
3 is likely to be lost.

Therefore, the present invention has been proposed in view of the above-described circumstances, and it is easy to insert a dry battery into a battery housing and take out the dry battery from the battery housing. An object of the present invention is to solve the problem of providing a battery insertion mechanism in which power supply to an electronic device is reliably performed by a dry battery stored in a storage housing and there is no risk of loss of members. .

[0010]

In order to solve the above-mentioned problems, a battery insertion mechanism according to the present invention has an opening in one direction and is rotatably supported on an outer casing of an electronic device. When the opening is turned to the outer housing side, the opening is closed by the outer housing, and the opening is turned to the outside by being turned in a direction away from the outer housing. When a battery housing to be opened and a dry battery for supplying power to the electronic device are housed in the battery housing, the battery housing is brought into contact with an electrode portion of the dry battery and connected to a power input portion of the electronic device. And a section member for supplying power from the dry battery to the power input unit.

Further, according to the present invention, in the battery insertion mechanism, the section member is formed of an elastic material, and is moved in conjunction with the rotation of the battery storage housing with respect to the outer housing. When the storage housing is rotated toward the outer housing, the storage housing is elastically pressed against the electrode portion of the dry battery stored in the battery housing, and the battery housing is separated from the outer housing. When the rotating operation is performed in the manner described above, the pressing force against the electrode portion is reduced.

The battery housing 1 is rotated with respect to the outer housing 1 by fitting into a pair of support shaft fitting holes provided on both sides of the lower portion of the opening 5 of the outer housing 4. It is movably supported.

When the battery housing 1 is rotated toward the outer housing 4, the bottom surface is substantially flush with the rear surface of the outer housing 4 as shown in FIG. The opening 5 is closed by the bottom surface, and the peripheral wall is housed in the outer housing 4. In this state, the opening of the battery housing 1 is closed by the outer housing 4. In this state, the battery housing 1 is releasably locked.

When the battery housing 1 is rotated in a direction away from the outer housing 4, as shown in FIG. It will be in the state protruded to the side. In this state, the battery housing 1 is open toward the outside with the open portion facing upward. In this manner, in a state where the battery housing 1 is open with the open portion facing outward, the dry batteries can be inserted into and removed from the battery housing 1. In this battery insertion mechanism, there is no member separated (separated) from the outer housing 4 even in the state where the battery housing 1 is opened with the open portion facing outward, as described above. There is no fear of loss.

In the battery housing 1, a slider 2 to which a section member 3 is attached is provided. This slider 2
Is located on one side of the battery housing 1, and is provided through a defective portion provided on one side of the peripheral wall of the battery housing 1.
It faces the outside of the battery housing 1. As shown in FIG. 4, the slider 2 is formed in a substantially flat plate shape, and is disposed so as to substantially close a defective portion of the peripheral wall of the battery housing 1. The slider 2 is slidable between a first position which is a position on one side of the battery housing 1 and a second position which is on the inner side of the battery housing 1 from the first position. It has been done.

The slider 2 has a pair of section members 3
