A selection indicator 2B, a right mirror selection indicator 2C indicating the operation of turning on the switch 100 at the same time as selecting to perform angle adjustment of the right mirror, and arrow indicators 2G indicating four directions of up, down, left and right for adjusting the angle of the door mirror, H, I, and J, and characters that are written as “OFF”, “L”, and “R” to inform the operator of the operation of the power indicator 2A and the left and right mirror selection indicators 2B and C Indicators 2D, E, and F are a power indicator 2A and left and right mirror selection indicators 2B and C, respectively. It is formed in the vicinity. These indicators 2A to 2J are formed by using white paint or the like on resin or rubber that transmits light.

  FIG. 3 is a top view of the transparent wiring member 3. The transparent wiring member 3 has electrostatic capacitance-type transparent electrodes 5A to 5C and G to J at positions corresponding to the indicators 2A to C and G to J other than the character indicators 2D to F of the case 1 in the plane direction. The transparent electrodes 5 </ b> A to 5 </ b> C and G to J are respectively connected to the control board 4 via transparent or non-transparent conductive wirings 10 formed on the transparent member 3 </ b> A. Moreover, as shown in FIG. 4, the shield member 11 which has the hole 11a in the position of indicators 2A-C and GJ other than the character indicators 2D-F is united with the upper surface of the transparent electrode film 3. It is stuck together. The shield member 11 other than the hole 11a is processed so as not to transmit static electricity to the transparent electrode 5 installed on the back of the shield member 11.

  Moreover, the control board 4 installed on the back side of the transparent conductive plate 3 is installed so that the plurality of LEDs 6A to J are in a one-to-one relationship with the indicators 2A to J in the plane direction, and is not illustrated. Electrically joined to motors 16 to 19 that adjust the vertical and horizontal angles of the left and right door mirrors.

  FIG. 5 is a block diagram showing an electrical configuration of the switch 100.

  The electrostatic capacitance-type transparent electrodes 5A to 5C and G to J are respectively connected to the capacitance detection circuits 12A to 12C and G to J on a one-to-one basis. The capacitance Cx is detected and output to the detection circuits 12A to 12C and G to J. The detection circuit 12A includes, for example, an oscillation circuit, generates a detection signal whose duty ratio changes in accordance with the capacitance Cx generated by the transparent electrode, and outputs the detection signal to the CPU 13. The CPU 13 is connected to the motor drive circuit 14 and the light source drive circuit 15 and outputs a control signal in accordance with detection signals input from the detection circuits 12A to 12C and G to J. The motor drive circuit 14 is connected to four motors 16 to 19 that adjust the vertical and horizontal angles of the left and right door mirrors, and drives the motors 16 to 19 in accordance with a control input from the CPU 13. Adjust the angle. The light source driving circuit 15 is connected to the LEDs 6A to 6J, and performs lighting control of the LEDs 6A to 6J in accordance with a control signal input from the CPU 13.

  Next, the operation of the vehicle-mounted door mirror switch 100 configured as described above will be described.

  A case where the operator adjusts the angle of the right door mirror upward will be described as an example. When the operator confirms the “R” character indicator 2F arranged on the upper surface of the case 1 and brings his finger close to the right mirror selection indicator 2C installed in the vicinity of the character indicator 2F, it is detected by the transparent electrode 5C. The detected capacitance Cx increases, and the detection circuit 12C outputs a detection value to the CPU 13. Here, the transparent electrode 5 other than the transparent electrode 5 </ b> C installed in the vicinity of the transparent electrode 5 </ b> C does not detect the capacitance by the shield member 11. The CPU 13 inputs a detection signal from the detection circuit 12C, recognizes that the right mirror has been selected, outputs a control signal to the light source drive circuit 15, and sets the LEDs 6A to J to the first lighting state. Here, when the LEDs 6A to J are turned on, the indicators 2A to J composed of the transparent wiring member 3, the transparent electrode 5, and the light transmitting material transmit the light of the LEDs 6A to J. It can be confirmed that the indicators 2A to 2J are lit.

  Next, when the operator confirming the first lighting state brings his finger close to the arrow indicator 2G indicating the upward angle adjustment, the CPU 13 inputs a detection signal from the detection circuit 12G, and the motor drive circuit 14 and A control signal is output to the light source driving circuit 15. The motor drive circuit 14 receives a control signal from the CPU 13 and drives the vertical adjustment right motor 18 that adjusts the vertical angle of the right door mirror in response to the control signal, thereby adjusting the angle of the door mirror upward. Further, the light source driving circuit 15 receives a control signal from the CPU 13 and sets the LEDs 6A to 6J to the third lighting state.

  When the operator confirms the third lighting state, confirms that the adjustment of the door mirror is completed, and brings his finger close to the power indicator 2A, the CPU 13 inputs a detection signal from the detection circuit 12, and the door mirror switch Set the power to OFF.

  The effect of the door mirror switch 100 configured as described above will be described.

  By using a transparent electrode for detecting capacitance in the basic structure of the door mirror switch, it is not necessary to use mechanical parts such as actuators and knobs, and the switch thickness can be flattened. Thereby, since a space can be ensured under the transparent wiring member 3, it becomes possible to arrange | position LED6 used as a light source.

  Also, by arranging the LED 6 and controlling the lighting of the LED 6 by the CPU 13, the operator can know the position of the switch and can easily perform the switch operation even at night.
