Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a power supply storage device used in electronic devices such as small tape recorders.

[Summary of the idea]

The present invention provides a case of an electronic device with a storage section in which a battery and a power adapter are selectively stored, and the storage section matches with an external power supply section provided on the power adapter and communicates with the outside. By providing a hole or a notch, the battery and the power adapter can be selectively used with a simple structure.

[Conventional technology]

Conventionally, as a power supply storage device for a small cassette tape recorder, etc., as shown in FIG. It is known that the device is designed to be installed. In this device, when the battery 1 is not used, the plug 5 connected to the external battery case or AC/DC adapter is inserted into the jack (not shown) provided on the external power supply section 2. External power is supplied to the main body 4.

[Problem that the invention attempts to solve]

In the conventional configuration shown in FIG. 2, the storage case 3 is detachably attached to the main body 4.
In addition to the problem of falling and breaking, the structure was also complicated, and there were also problems in terms of strength.

[Means for solving problems]

In the present invention, a case of an electronic device is provided with a storage section in which batteries and a power adapter are selectively stored, and the storage section is communicated with the outside at a position that matches the external power supply section provided on the power adapter. A hole or cutout is provided for the

[Effect]

The configuration is simple, and batteries and power adapters can be stored stably.

〔Example〕

FIG. 1 shows an embodiment in which the present invention is applied to a small cassette tape recorder.

In FIG. 1, a tape recorder case 10
On one side 10a, there are PLAY, STOP, FF,
Operation buttons 11 such as REW are provided. A power supply storage section 12 having an opening 12a in the one side surface 10a is provided at one end of the case 10. An opening/closing lid 13 is provided in the opening 12a of the power supply storage section 12 with one end thereof being rotatable.

This power supply storage section 12 is configured to selectively store a battery 13 or a power adapter 14. The battery 13 is a nickel cadmium battery, for example, and is formed into a thin rectangular parallelepiped shape as shown in the figure, with a positive electrode 15 provided on the top surface and a negative electrode (not shown) provided on the bottom surface. .

The power adapter 14 has the same external dimensions and shape as the battery 13, and has a positive terminal 1 on the top surface.
6 is provided and a negative terminal (not shown) is provided on the bottom.
is provided. Further, a jack 17 for supplying external power is provided on the side surface of the power adapter 14.

On the power supply compartment 12 side, a terminal 18 is provided on the back surface of the opening/closing lid 13 to which the positive electrode 15 of the battery 13 or the positive terminal 16 of the power adapter 14 comes into contact. is the negative electrode of the battery 13 or the power adapter 1
A terminal 19 is provided to which the negative terminal of No. 4 is contacted. The terminals 18 and 19 are connected to a predetermined circuit on a printed circuit board (not shown) provided inside the case 10.

The power supply storage section 12 is also provided with a hole 20 on its side surface that communicates with the outside. This hole 20 is provided at a position where the jack 17 is aligned with the hole 20 when the power adapter 14 is stored in the power storage section 12.

Incidentally, the jack 17 may also be provided on the side of the power adapter 14 opposite to that shown in the drawing. Also, the hole 20
Instead, a notch extending downward from above the opening 12 may be provided.

According to the above configuration, the battery 13 is provided in the power supply storage section 12.
If you store the battery and close the opening/closing lid 13, this battery 13
The positive electrode 15 and the negative electrode are connected to terminals 18 and 1, respectively.
By touching 9, the electrical circuit can be supplied with a power supply voltage.

Moreover, if the power adapter 14 is stored in the power supply storage part 12 and the opening/closing lid 13 is closed, this power adapter 1
The positive terminal 16 and the negative terminal of No. 4 are terminal 1, respectively.
8 and 19, and the jack 17 is in contact with the hole 2.
0 and is exposed to the outside.

In this state, connect the DC power supply plug 21 from the outside.
By connecting this, power supply voltage can be supplied to the electric circuit through the power adapter 14. Incidentally, the plug 21 is connected to an AC/DC converter or an external battery via its cord 22.

According to the embodiment of the present invention described above, the battery 13
Since the power supply adapter 14 and the power supply adapter 14 are formed to have the same size and shape, they can be easily replaced and used in the common power supply storage section 12. Further, when the power adapter 14 is housed and the plug 21 and the jack 17 are connected, the connection is made through the hole 20, so the strength is reinforced and the connection is made stably. Furthermore, it can be determined through the hole 20 whether the battery 13 or the power adapter 14 is stored in the power storage section 12. Furthermore, it is possible to incorporate electrical components inside the power adapter 14 that cannot be inserted into the case 10 side. For example, a capacitor or the like can be built in to improve the regulation of an external power source.

[Effect of idea]

According to the present invention, the extremely simple structure allows the battery and power adapter to be easily replaced and used, and the provision of the hole 20 (or notch) ensures stable connection with the plug. In addition, it is possible to obtain effects such as being able to know whether a battery or a power adapter is stored in the power storage section.
