A limit switch, 14 is a power control circuit, 15 is a holder, and 16 and 17 are springs. The three terminal rods 11 for battery, ground, and power are slidably fitted in the holder 15, and are urged by a spring 16 in a protruding direction from the bottom surface 10 of the device main body. The terminal cover 12 is slidably fitted in a hole 20 in the bottom surface 10 and is urged by a spring 17 in a protruding direction from the bottom surface 10. The terminal cover 12 is provided with a hole 21 through which the terminal rod 11 penetrates, and the terminal rod 11 is mechanically protected by the tip of the terminal rod 11 being substantially flush with the terminal cover 12. The limit switch 13 is connected to the terminal cover 1.

The operation of the charging terminal 4 is as follows. When the handy terminal 1 is placed in the depression of the bottom surface 10, the bottom 1 a hits the terminal cover 12 and overcomes the urging force of the spring 17 to retreat the terminal cover 12 downward. Then, the terminal 1b on the bottom 1a comes into contact with the tip of the terminal rod 11 to be in a physically connected state, and the spring 1
The terminal rod 11 is retracted downward together with the terminal cover 12 by overcoming the biasing force of No. 6. At this time, the limit switch 13 has not been operated, and power has not been supplied to the terminal rod 11. When the terminal rod 11 and the terminal cover 12 are further retracted, the terminal cover 12 activates the limit switch 13 and the power supply control circuit 14 for turning on / off the supply of power to the terminal rod 11 is turned on. Power is supplied.
