[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a communication device, a charging device for the communication device, and a rechargeable battery. Various types of communication devices, in particular, portable wireless communication devices utilizing radio waves, which can carry out communications while traveling, can perform desired communication at any time and from any place. Wireless telephone communication devices and the like are used in various fields.

[0002] Such a communication device is configured such that a rechargeable battery is detachably attached to a power source and can be efficiently used by repeatedly charging the battery. Further, by preparing a spare battery and charging the spare battery, when the used battery is exhausted, it can be immediately replaced with the spare battery and continuous communication can be performed.

[0003] In a case where communication and charging can be easily performed in a relatively short time, a small battery can be used so that the battery can be used in a lightweight state, and when a communication time is long or charging cannot be performed easily. In such a case, a large-sized battery having a large battery capacity can be attached and used.

[0004] The battery can be charged by using the power supply of the vehicle, but usually, it is generally charged by using a commercial power supply and using a charging device. Such a communication device is carried in a case with clues made of natural leather or artificial leather for carrying, so that it is not damaged or the operation part is not moved carelessly. Protected. However,
Since it is cumbersome to take out and house the case to communicate, it is necessary to expose the minimum necessary operation and use parts so that communication is possible even when housed in the case.

[0005] The battery is charged on a daily basis, depending on the frequency of communication, so that connection to the charging device is configured to be extremely easy. For example, by simply inserting the communication device with the battery connected thereto from above into the opening of the recess of the charging device, the terminals of the charging device and the battery are connected by the weight of the communication device. By pulling up and removing the communication device even when charging is completed or during charging,
