、Ｃ２の放電用抵抗である。As described above, when the battery 8 is attached to the camera-integrated handy VTR body 1, the + side terminal I3 and the -@ terminal 14 come into contact with the + side terminal and the - side terminal on the body 1 side (not shown), respectively. The switch 10 is folded to the opposite side from the illustrated state. When the switch is flipped to the opposite side, the battery 1
1, the capacitor C2 is charged via the resistors R1 and R2, and during this charging period, the transistor T which is the switching means is charged.
r is turned on. As a result of this turning on, current flows from the NiCd battery 11 to the load resistor 15 through the temperature fuse 12. This load resistor 15 is used to measure the terminal voltage of the battery 11 by flowing a certain amount of current, since an accurate value will not be obtained if the terminal voltage of the battery 11 is measured without applying a load. Therefore, comparators 16a~
At 16c, the battery 11 is connected while the current is flowing through the load resistor 15.
Therefore, if the threshold voltage of the comparator is set to 16a>16b>16c, when the battery 11 is fully charged, the LEDs 9a to 9c will be applied.
lights up, and when battery 11 is used to some extent, press L.
The LEDs 9b and 9c are turned on, and when the capacity of the battery 11 gradually decreases, only the LED 9c is turned on. And battery 1
When the capacity of 1 is completely exhausted, the LED 9a
None of the items 9c to 9c are lit. In addition, R3 is the capacitor C1
, C2 are discharge resistors.
