Description of the Related Art In general, a radio selective calling receiver of this type is provided with a display unit, and when displaying message information on the display unit, the display unit is illuminated for easy viewing. Further, the radio selective calling receiver can display not only message information but also general information (for example, time display by a clock function) based on a program stored in hardware and a memory on a display unit. Selective call receivers are also known. In such a selective call receiver, generally, even when general information is displayed, the above-described lighting function operates, that is, the lighting function operates even when the general information being displayed is not required. However, the receiver power is wasted. As a result, it is necessary to newly provide an illumination lighting switch for selectively performing illumination during the display of general information.

Here, the operation of the conventional radio selective calling receiver will be outlined with reference to FIG. The illustrated radio selective calling receiver includes a reception control unit 11. A transmitting station (not shown) transmits a transmission signal having a plurality of selective calling signals and a message signal following each of the selective calling signals. This transmission signal is received as a reception signal by the reception control unit 11 via the antenna 12, where it is amplified and demodulated and provided to the decoder 13 as a demodulated signal. In the decoder 13, a call number unique to the receiver is stored as a self-call number, and when the demodulation signal is received and the call number indicated by the selected call signal matches the self-call number, the decoder 13 informs the notification unit. 14 is activated to notify the call (the notification unit 14 notifies reception by sounding and / or light). Further, the decoder 13 supplies a message signal following the selective calling signal to the control unit 15.

The control unit 15 includes a central processing unit (CPU) 15
a, a ROM 15b, and a RAM 15c.
The OM 15b stores a program that operates on the CPU 15a (for example, a control program). CP
When U15a receives the message signal, it stores this message signal in the RAM 15c as message information.
When the display changeover switch 16 is operated, the CPU 15a reads out the message information from the RAM 15c and
7 displays message information. At this time, the CPU 15a
Drives the illumination unit 18 to illuminate the display unit 17.

When message information is not displayed, the CPU 15a displays general information on the display unit 17 in response to an operation signal from the decoder 13 or a ROM program. At this time, when the illumination lighting switch 19 is operated, C
The PU 15a drives the illumination unit 18 to illuminate the display unit 17. The CPU 15a sets a predetermined time in a built-in timer for operating the illumination lighting switch 19, and starts counting time. When the counting of the predetermined time is completed, the CPU
15a turns off the lighting unit 18. Further, when the display changeover switch 16 is operated while the message information is displayed on the display unit 17, the CPU 15 a executes switching from the message information to the general information, and displays the general information on the display unit 17. At this time, the CPU 15a turns off the illumination unit 18. When the display changeover switch 16 is operated while the general information is displayed, the CPU 15a executes switching from the general information to the message information, displays the message information on the display unit 17, and displays the message information on the illumination unit 18. To illuminate the display unit 17. At this time, the CPU 15a sets a predetermined time in the built-in timer and starts counting time. When the measurement of the predetermined time is completed, the CPU 15a switches the display from the message information to the general information, and
Turn off the light.
