DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a portable wireless device according to the present invention. In FIG. 1, reference numeral 1 denotes a wireless unit for receiving, detecting and outputting a transmission signal such as a selective call signal including a message from the outside by radio, and 2. Is wireless unit 1
Is a decoder for judging whether or not the call number in the output signal of the above and the own call registration number stored therein match. The decoder 2 informs the control unit that its own call registration number has been called and that there has been a message following the call number in the output signal. A control unit 3 controls a main display area driving unit 5 and a sub display area driving unit 6 to transmit a message from the decoder 2 to a main display area 12 constituting a screen of the display unit 11.
And the sub-display area 13 is displayed in the entire combined area.

The main display area 12 is a display area capable of displaying several characters by dot matrix display and capable of sufficiently displaying a received message. On the other hand, the sub-display area 13 is a display area in which a display is performed by a segment or a single function is displayed only by lighting (ON) with a symbol designed by one dot, and for example, “ON”, “Speaker”, A symbol mark such as “battery” can be displayed in the display area. FIG. 2 shows a main display area 12 and a sub-display area 13 for dividing the screen on the display unit 11.

As described above, only one type of symbol mark can be displayed in the same portion of the sub display area 13, but various types of characters can be displayed in the main display area 12 by dot matrix display by selectively lighting each dot. Can be displayed. The display capability difference between the display areas 12 and 13 is directly proportional to the circuit size of the display drive units 5 and 6. Therefore, in order to display the main display area 12, a large-scale main display area driving unit 5 is required, and the consumed current increases. On the other hand, a small-sized sub-display-area driving unit is sufficient to display the sub-display area 13,
Compared with the display current in the display in the main display area, an extremely small current consumption is required.

Further, the contents simultaneously displayed on the main display area 12 and the sub display area 13 which are the entire display area of the screen of the display section 11 become the current time display which is made at the end of the notification operation. Although the current time can be displayed in the segment display of the sub display area 13, if all time information such as year, month, day, and day of the week is displayed simultaneously, the display unit 11
Is required to be applied to the sub-display area 13. Because, as described above, only one type of symbol mark can be displayed in the same place as described above, a display area dedicated to time display must be secured, and therefore the main display area 12 must be narrowed. It will not be practical. Therefore, by performing the current time display in the main display area 12, the performance of the portable wireless device with a display function can be brought out. However, as described above, continuation of the display in the main display area 12 requires a large amount of current consumption. Therefore, the current consumption is reduced by the following method.

In FIG. 1, reference numeral 4 denotes an operation switch operated to set various functions and select functions. Reference numeral 7 denotes a speaker, a vibrator, a light emitting diode, and the like which perform a ringing alarm operation under the control of the control unit 3. A notification drive unit 9 that drives the notification unit 8 is an illumination drive unit that turns on or off the display illumination unit 10 of the display unit 11 under the control of the control unit 3 in accordance with the result of the illuminance detection unit 14 detecting the illuminance of the surrounding environment. .

Next, the operation of the portable wireless device of the present invention will be described with reference to the flowchart shown in FIG. First, when a power switch (not shown) is turned on and a power voltage is applied to each circuit of the wireless device (step S21), the notification drive unit 7 drives the notification unit 8 under the control of the control unit 3 to generate a sound or the like. To perform an informing operation for notifying the initial operation (step S22).
When the initial operation is completed, the control unit 3 causes the illuminance detection unit 14 to detect the surrounding brightness. From the detection result, if it is bright, the current time display is performed on the entire area including the main display area 12 and the sub display area 13. (Step S24), and if dark, display is performed only in the sub-display area 13 (Step S2).
5). Next, when the user operates the operation switch 4 of the predetermined function (step S26), the control unit 3 controls the illuminance driving unit 9 if it is dark, and displays it based on the detection result by the illuminance detection unit 14 (step S29). The illumination unit 10 is operated (step S31), and after illuminating the display unit 11, a function is displayed according to a switch operation. On the other hand, when it is bright, function display is performed without illumination. Here, the function display is a display on the screen that allows the user to perform a series of operations such as switching of the current time, notification means, and confirmation of a previously received message. When the switch operation is completed in this way (step S32), under the control of the control unit 3,
The display operation is stopped (Step S33), and Step S2 is performed.
It will return to 3.

On the other hand, if the operation switch 4 has not been operated in step S26, it is checked whether or not there is a call (step S27). If there is a call, the control unit 3 controls the notification drive unit 7 Then, notification is performed by the notification unit 8 (step S34). Subsequently, when the user operates the operation switch 4 (step S35), the control unit 3 stops the notification operation (step S36). Then, the control unit 3 controls the illuminance driving unit 9 to operate the display illuminating unit 10 if dark (step S37) and illuminates the display unit 11 based on the illuminance detection result by the illuminance detecting unit 14 (step S37). Then, the received message information is displayed (39). On the other hand, if the display is bright,
Only the message display by 1 is performed.

Therefore, as long as the user does not operate the switch and is not called, step S23 → step S
T24 (25) → Step S26 → Step S27 → Step S28 → Step S23 The looping operation is continued. If the surroundings are bright, the main display area 12 and the sub display area 1
3 is performed, and if dark, only the sub-display area 13 is performed.

[0016] Incidentally, in the embodiment, the dark Itoki the display by only the sub display area 13, also in view of only the main display area 12 when bright, possible only slightly change the control operation of the controller 3 It is. In the above-described embodiment, the case has been described where the current time is displayed at the time of standby. However, the display content of the standby character need not be the time . The displayed message content may be continuously displayed, or the name of the operator company may be displayed. Also, as an example of a portable wireless device with a display function, a pager has been described above as an example, but a mobile phone or a PHS may be used as long as it is a portable wireless device with a display function.
