, 6f, and the movable contact 6a is movably connected to the cover 2 so that the tilt angle of the display 3 can be detected. The above fixed contact 6b
6f, the central fixed contact 6b is directly connected to one lead terminal of the brightness adjustment variable resistor 5, and has a display scale indicating that the display 3 is at the initial state of the display screen. It corresponds to "0". Other fixed contact 6c
, ad, 6e, and 6f, resistors 7, 8, 9, and 10 are connected to form a series circuit with the variable resistor 5, respectively, and fixed contacts 6c and 6d are connected to the rear side of the display 3. The fixed contacts 6e and 6f correspond to the display scales r-IJ and r-2, respectively, which indicate the tilt of the display 3 toward the front side, and the fixed contacts 6e and 6f correspond to the display scales r+l and [+24, respectively, which indicate the tilt of the display 3 toward the front side. . The brightness adjustment switch 6 and the variable resistor 5 constitute a brightness adjustment circuit 11 that changes the brightness of the display screen according to the tilt angle of the display 3.

る。The tilt angle of the display 3 is set so that the tilt angle of the display 3 is in the initial state shown in FIG. Adjust the brightness to an appropriate level. When the inclination angle of the display device 3 is displaced from the above-mentioned initial state to the rear side as shown in FIG. 1B or to the front side as shown in FIG. It switches in response, and the displacement of the above-mentioned inclination angle is detected. Now, if the display 3 is displaced backward from the initial state and changes to the display scale "-1" position, as shown in FIG. 1b, for example, the display screen of the display 3 becomes difficult to see with the conventional display. . However, in the 1-notation structure, at this time, the movable contact 6a of the brightness adjustment switch 6 switches to the fixed contact 6C,
Since the resistor 7 is connected in series to the brightness adjustment variable resistor 5, the brightness is increased and the display screen of the display 3 becomes easier to see.
すなわち、表示器３の傾き角度が初期状態から変化して
も、自動的に輝度が調整されるので、輝度調整用可変抵
抗器５の調整操作が不要となり、使い易くなる。That is, even if the inclination angle of the display device 3 changes from the initial state, the brightness is automatically adjusted, so the adjustment operation of the brightness adjustment variable resistor 5 is not required, making it easier to use.
なお、上記輝度調整スイッチ６の切り換え数は適宜増数
