Document Type and Number:
Japanese Patent JP3112507
Kind Code:
B2
Abstract:
PURPOSE: To provide a battery operating type device which allows a deeper discharge so as not to reduce the discharge capacity by memory effect, dispenses with an exclusive discharge means, thus requires no enlargement of the device for the discharge means, and also provides an advantageous cost.
CONSTITUTION: The power source part of an electron steel camera which is a battery operating type device using a Ni-Cd battery 30 as a power source, and its output is outputted as the line of a power source voltage V0 through a stabilizing circuit 31, and the power sources of four systems of power source lines V1, V2, V3, V4 are supplied to determined circuit parts, respectively, through a saving circuit 32 which is a power source system control means for controlling the power supply by a CPU 1. At the time of discharge operation, any one of the power source lines V1, V2, V3, V4 is selected as a load by the CPU 1.
