[0002]

2. Description of the Related Art In a communication device such as a portable telephone, an information processing device such as a laptop personal computer, or a portable device such as a video / audio device such as a portable VTR, a secondary battery such as a nickel-cadmium battery is used as a power source. Is used. These portable devices tend to be miniaturized year by year in order to increase the degree of freedom in the form of use and expand the use. In order to reduce the size of the device, it is necessary to reduce the size of the secondary battery. In recent communication devices and video / audio devices, the size of the secondary battery is reduced with each model change.

[0003]

With the miniaturization of such portable devices and secondary batteries, new chargers corresponding to their shapes have been required. In addition, there are a type in which the secondary battery is charged alone and a type in which the secondary battery is charged while attached to a portable device, and these cannot be handled by a single charger.

[0004] It is an object of the present invention to make it possible to charge a rechargeable battery either in a state in which the rechargeable battery is attached to a portable device or in a rechargeable battery alone, and to be able to handle a miniaturized rechargeable battery. An object of the present invention is to provide a device charging device.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows the structure of a charger of a portable device charger according to an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes a lower case, and 2 denotes an upper case, each of which is formed by molding a synthetic resin. The combination of the lower case 1 and the upper case 2 constitutes a charger housing. A printed wiring board 3 on which a plurality of electronic components are densely mounted (each component is omitted) is provided in the housing. Further, in the figure, reference numerals 4a and 4b denote connection terminals that come into contact with a charging electrode of a secondary battery described later, and reference numerals 7a and 7b denote secondary battery holding portions that hold a charging electrode forming portion of the secondary battery. Reference numerals 5a and 5b denote thick-type secondary battery holders that hold the protruding portions other than the charge-electrode-forming portion when the charging electrode forming portion of the thick-type secondary battery is mounted on the secondary battery holding portion 7a or 7b. . Further depression indicated by 8, the charging electrode forming portions of the secondary battery remains attached to the portable device battery holding portion 7a
A portable device holding portion for holding the portable device between the portable device and the thick secondary battery holding portion when the portable device is attached to the portable device; Was
Projection . An indicator 10 such as an LED indicating the charging process (during charging, charging completed, etc.) of the secondary battery is provided on the front of the charging device.

Next, FIG. 2 shows a state where two types of secondary batteries having different sizes are mounted on a charger. In FIG. 2, 12
Denotes a thin secondary battery, and 13 denotes a thick secondary battery. The thin secondary battery 12 has a charging electrode formed at the lower end in the figure, and the charging electrode forming portion is mounted on the secondary battery holding portion 7b. Thus, the connection terminal 4b on the charger side contacts the charging electrode of the secondary battery 12 to perform charging. On the other hand, a charging electrode is also formed at the lower end of the thick secondary battery 13 in the drawing, and by attaching the charging electrode forming portion to the secondary battery holding portion 7a, the connection terminal 4a charges the secondary battery 13 Touch the electrodes. As is apparent from a comparison between the two secondary batteries 12 and 13, the thick secondary battery 13 has a protruding portion 14 provided on a part of the thin secondary battery 12 to increase the capacity. The thick secondary battery holding portion 5a of the charger holds the protruding portion 14 of the thick secondary battery 13, thereby dispersing the load on the secondary battery holding portion 7a and the charging electrode forming portion of the secondary battery 13. . The thin secondary battery 12 can be mounted on the secondary battery holder 7a, and the thick secondary battery 13 can be mounted on the secondary battery holder 7b.

Next, FIG. 3 shows a state in which the portable device with the secondary battery attached is mounted on the charger. In FIG. 3, reference numeral 11 denotes a portable device, and a thick secondary battery 13
Is installed. By attaching the portable device 11 to the portable device holding portion 8 with the secondary battery still attached, the charging electrode of the secondary battery 13 is connected to the connection terminal 4 on the charger side.
a. In this state, the thick secondary battery holder 5
“a” supports the rear surface of the thick secondary battery 13, and the protrusion 9 locks the lower front surface of the portable device 11. In addition, it is also possible to attach a thin type secondary battery or a thick type secondary battery alone to the secondary battery holding portion 7b, and charge the battery simultaneously or sequentially continuously.

[0010]

According to the present invention, with the secondary battery attached to the portable device, the charging electrode is exposed to the outside of the secondary battery, and the secondary battery holder and the secondary battery are provided on the charger side. By providing a connection terminal that comes into contact with the charging electrode when the secondary battery is mounted alone or integrally mounted with the mobile device, and a mobile device holding unit that holds the mobile device with the secondary battery attached, It can be charged in any state integrated with the portable device. In addition, since the secondary battery is held by the charging electrode forming portion, it is possible to charge a plurality of types of secondary batteries having a common charging electrode forming portion and different shapes. In addition, the connection terminals
