Title:
DRIVE DEVICE
Document Type and Number:
Japanese Patent JP3468036
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a highly reliable drive device, which can surely operate a motor in correspondence with the operation of a switch, even if leaking due to an accident such as immersed in water or the like has occurred, in the drive device for operating a relay, which supplies an electric power source to a motor 1 corresponding to the operating state of the switches 4 and 5.
SOLUTION: Transistors 21a and 22a and transistors 21b and 22b, which turn on and off the power-supply sides and the grounding sides of relay coils 2a and 3a, and a microcomputer 23 are provided. The process for reading the magnitudes of the terminal voltages of switches 4 and 5 and discriminating that the operation of the switches has been made. The drive signals, which turn on the both transistors on the power supply side and the ground side corresponding to the case when the operation of the switches is discriminated, is outputted.
