Abstract

PURPOSE:To reduce the capacity of a portable, small electronic equipment main body by that of a voltage-fluctuation absorbing capacitor by housing the capacitor in a vacant space forming outside batteries in a battery pack. CONSTITUTION:A battery pack 1 holds two cylindrical batteries 2 with the cylindrical side faces of the batteries 2 adjoining each other. A voltage- fluctuation absorbing capacitor 3 is housed in a vacant space 4 forming outside the batteries 2 in the pack 1. The capacitor 3, which was housed in a portable, small electronic equipment main body 5, is held in the space 4 in the pack 1, whereby the capacity of the portable, small electronic equipment main body and the space 4 in the pack 1 can both be reduced. The portable, small electronic equipment main body can thus be made smaller and thinner and its portability can be enhanced.

2. Description of the Related Art FIGS. 2 and 4 are cross-sectional views of a conventional battery and a portable small electronic device. Hereinafter, description will be given with reference to FIGS. 2 and 4. According to the conventional technique, the voltage fluctuation absorbing capacitor 3 is provided in the portable small electronic device main body 5, and the volume of the portable small electronic device main body 5 must be increased by the volume of the capacitor 3. Further, since the battery pack 1 contains a plurality of cylindrical batteries 2, an empty volume 4 is created outside the batteries 2 in the battery pack 1. As a publicly known example, Japanese Patent Application Laid-Open No. 3-13003 discloses a system utilizing an empty volume.
The publication describes a portable small electronic device in which an auxiliary antenna is arranged outside the battery in the battery storage chamber.

According to the prior art, since the capacitor 3 for absorbing the voltage fluctuation caused by the sudden change of the load is inserted inside the portable small electronic device body 5, the capacitor 3 has a volume corresponding to that of the capacitor 3. However, there is a problem that the portable small electronic device body 5 is enlarged. Further, since the battery pack 1 contains a plurality of cylindrical batteries 2, the battery pack 1
There is a problem that an empty volume 4 is generated inside and outside the battery 2.
Therefore, it is a problem to be solved by the present invention to reduce the volume of the portable small electronic device body 5 and to reduce the empty volume 4 in the battery pack 1.
