作部・表示部を照明する方法をとっている。The conventional method of illuminating the operation and display sections is only when the vehicle's night light switch is turned on, as shown in the circuit diagram in the Hitachi AM Car Radio TM-771D service book published in June 1981. A method is used to illuminate the operation and display sections of in-vehicle equipment. Alternatively, in some devices, a method is adopted in which the operation section and display section of the vehicle-mounted device are illuminated only when the power switch of the vehicle-mounted device is turned on.

困難であるという問題があった。In the above conventional technology, the method of illuminating the operation parts and display parts of in-vehicle equipment by turning on the vehicle's lighting switch at night is such that when the vehicle is stopped and the lighting switch is turned off, the operation part of the in-vehicle equipment is illuminated. - No consideration was given to the fact that the display section could not be illuminated, making it difficult to operate in-vehicle equipment at night.

車載用機器の操作が困難であるという問題があった。In addition, with the method of turning on the power switch of in-vehicle equipment and illuminating its operation and display parts, even if the vehicle's lighting switch is turned on at night, the power of the in-vehicle equipment is not turned on. Otherwise, the illumination of the operation section and display section would not turn on, and there was a problem that no consideration was given to operation and display at night, making it difficult to operate the in-vehicle equipment at night.
本発明の目的は、車載用機器の操作部・表示部の照明方
法を改善し、夜間の車載用機器の操作性を向上させるこ
とにある。SUMMARY OF THE INVENTION An object of the present invention is to improve the method of illuminating the operation section and display section of an in-vehicle device, and to improve the operability of the in-vehicle device at night.

設けたものである。In order to achieve the above purpose, the lights on the operation and display sections of on-board equipment are turned on at night, both when the vehicle's lighting switch is turned on and when the on-board equipment is turned on. It is something that To do this, we need to create a switching circuit that turns on the lights of the onboard equipment when either the power signal when the vehicle's lighting switch is turned on or the power signal when the onboard equipment is turned on. It was established.
２つの電源信号のうち一方が投入されれば、照明回路に
電源が供給されるオア回路を採用している。同時に２つ

作することはない。An OR circuit is used in which power is supplied to the lighting circuit when one of the two power signals is turned on. Even if two power supply signals are applied at the same time, there will be no malfunction because the power supply voltage is the same.
以下、本発明の一実施例を第１図、第２図によす説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.
第１図に車載用機器４の照明部構成図を示す。FIG. 1 shows a configuration diagram of the lighting section of the vehicle-mounted equipment 4.
操作文字表示部１と液晶表示部２と電源スイッチ３とか

される。Furthermore, when the power switch 3 of the in-vehicle device 4 is turned on, power is supplied to the operation section/display section illumination lamp 6 through the diode 12. The diode 11 and the diode 12 form an OR circuit, and if either the lighting switch 9 of the vehicle 10 or the power switch 3 of the in-vehicle equipment 4 is turned on, the operation part/mounting part illumination lamp 6 is turned on. tg is supplied.

果がある。According to the present invention, since the vehicle lighting switch is always turned on while the vehicle is running at night, the switch is used to illuminate the operation section and display section of the in-vehicle equipment, so that the location of the operation section etc. can be clearly identified. can. In addition, when you want to stop the vehicle and turn off the vehicle's lighting switch to operate the in-vehicle equipment, you can turn on the power switch of the in-vehicle equipment, then turn off the vehicle's lighting switch. Since the display section is illuminated, there is no need to worry about inconveniences such as not being able to understand the operation section due to darkness inside the vehicle at night, and the operability at night is greatly improved.
