FIG. 8 is a cross-sectional view of the battery holding unit of the portable electronic device of FIG. 7, showing a state when the battery is attached and detached.

The third embodiment is the same as the first embodiment except for the method of holding the battery, and therefore, the same parts are not described, and are denoted by the same reference numerals as the first embodiment.

Referring to FIGS. 7 and 8, the battery 120 is engaged with and held by the support 130 in the first embodiment.
30 without using the battery 120
11 is engaged with and held by the case 110 on the side surface.

For this purpose, a pin 324 is provided on the both sides orthogonal to the bottom surface of the battery housing 111 of the battery 120 near the contact point 121, and the pins 324 are engaged with both sides orthogonal to the bottom surface of the battery housing 111. The slide groove 313 which can slide is formed. Slide groove 31
3 is a pin 324 having one end opened at the upper surface of the battery storage portion 111 of the case 110 and engaged with the slide groove 313.
Is formed at the other end so that the terminal 170 provided in the battery housing 111 and the power supply contact 121 of the battery 120 come into contact with each other. A leaf spring 390 is provided at the bottom of the battery housing 111, and the pin 324 is engaged with the slide groove 313 to urge the battery 120 inserted into the battery housing 111 in a direction to jump up.

The pin 324 is inserted into the slide groove 313, and the battery 120 is inserted into the slide groove 313.
When the battery 120 is pushed into the battery housing 111 against the urging force of the leaf spring 390, the second hook 140 is pushed by the action of the tapered surface of the second hook 140,
Finally, the second hook 140 is engaged with the step 123 of the battery 120, and the battery 120 is
It is fixed in 1.

In the third embodiment, the structure having the leaf spring 390 has been described. However, even without the leaf spring 390, the battery 120 does not automatically jump up, but the cover is detached due to the drop impact and the power supply terminal of the present invention. The purpose of avoiding the deformation of can be achieved.

Although the above description has been given as a battery holding method for portable electronic devices in general, the present invention is particularly effective as a battery holding method for a portable telephone having a large chance of being damaged by an impact such as dropping.

[0039]

As described above, the present invention has the following effects. That is, the first effect is that when the device receives an impact such as dropping, it is possible to prevent the cover from falling off and the power supply terminal from being deformed. The reason is that since the battery is fixed in the battery storage portion by the independent holding means and the fixing means, the inertial force that the battery receives when the battery falls or the like is not directly applied to the cover or the terminal.

The second effect is that it is possible to prevent the deformation of the terminal due to the attachment / detachment of the battery. The reason is that since the direction of attachment / detachment of the battery is regulated by the movement of the holding means, it is possible to prevent an attachment / detachment method in which an excessive force is applied to the terminal.
