Title:
CONTROLLER FOR MOTOR DRIVEN HOUSING TYPE DOOR MIRROR
Document Type and Number:
Japanese Patent JP3150883
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a compact small volume door mirror by providing an NPN type transistor and PNP type transistor having respectively emitters and collectors bypassing both ends of a relay for making a current value flowing in the zero or minute and connected to both ends of the relay.
SOLUTION: A contact between a drive motor M and resistance R3 is also connected to the resistance R2 and the other end side of the resistance R2 is branched into two systems. One system is connected to the base of an NPN type transistor Q1 and the other is connected to the base of a PNP type transistor Q2. The collectors of the respective transistors Q1, Q2 are together connected to the connection of a relay coil Rc and resistance R1 and emitters are together connected to the contact C2. A relay circuit 3 and relay controlling circuit 4 can be provided as a unit in a cabin of a vehicle and since the circuit can be simply miniaturized, these circuits can be combined with a switch circuit 2 to be incorporated in a switch unit or a mirror housing.
