ったことを知らせる。In the following, a description will be given with reference to the flowchart of FIG. 5. Since no current flows in the standby state, a flag of N = 1 is set. Initially, since the flag C is 0, the current presence / absence routine is circulated. However, when the adapter (3) is connected to the charger (2), a charging current flows, and the capacity display device (14) is turned on. Is notified that charging has started. Thereafter, the display device (14) is turned off, a flag of C = 1 and N = 0 is set, and charging is continued. After the flag of N = 0 is set, the display device (14) is not turned on. When charging is completed and the switch in the charger is turned off, the charging current will be lost,
After setting the flag of N = 1, all the LEDs of the capacity display device (14) are turned on to notify that the capacity of the battery pack (4) has reached 100%.

ック電池（４）の残存容量が分かるようになっている。In this state, remove the adapter (3) from the charger (2),
When the switch (7) is turned on while connected to the VTR (1), a discharge current flows. Since N = 1, the flag of C = 0 is set, and then the capacity display device (14) is turned on. Immediately after the start of use, the capacity display device (14) turns on all the LEDs. As time elapses, the arithmetic unit (16) integrates the current flowing through the current detection unit (15), subtracts the integrated value from the battery capacity, and then sets a flag of N = 0 to go around the routine. As the capacity of the battery pack (4) decreases, the capacity display device (14) decreases the number of lighted LEDs so that the remaining capacity of the battery pack (4) can be known.

以上の説明では、充電中、アダプタ（３）の容量表示
