However, when the conventional receiver is used, if the user does not carry the receiver at the time of reception and the user is at a remote position as shown in FIG. You can recognize that the receiver is receiving a ringing sound or blinking the LED, but the message displayed on the display by the user indicates whether the call to the receiver is an emergency call or another call. It will be understood for the first time when you see. Therefore, in the conventional message display type wireless call receiver, when the user does not carry it, it is not possible for the user to instantly recognize whether the caller is an emergency call or another call. . An object of the present invention is to solve the above problems and to provide a message display type wireless call receiver having a display function that allows a user to recognize the intention of a caller without instantaneously seeing the message. To provide.

A message display type radio paging receiver of the present invention has a liquid crystal display section and decodes a message code sent from a calling source following an individual calling number to display the liquid crystal display. In a message display type radio paging receiver configured to be displayed on a liquid crystal display unit, a light emitting element, which is arranged inside the case near the liquid crystal display unit and has an emission color different from that of the liquid crystal display unit, and a receiver And a drive circuit for causing the light emitting element to emit light according to an output signal from the call type detection unit, and a value of a specific digit of the message code is called. It is characterized in that the type detecting unit is configured to emit light when the light emitting element is compared with a value stored in advance in the type detecting unit.

1 is a block diagram showing a first embodiment of the present invention. In the figure, 1 to 12 are the same components as in the prior art. The present invention is realized by adding a portion surrounded by a broken line, that is, a call type detection unit 13, a light emitting element 15 such as an LED, and a drive circuit 14 to the conventional configuration. The call type detection unit 13 is connected to the data bus (parallel signal) of the control unit 3. A parallel input comparison circuit is built in the call type detection unit 13, and the result of the comparison is output in 1 bit. The operation of the call type detection unit 13 will be described. When the parallel signal output from the control unit 3 and input to the call type detection unit 13 is used as a 4-bit parallel input signal and a message display type wireless call receiver that displays numbers is used as an example, In synchronization with the reception, a synchronization signal for capturing 4-bit parallel data is given from the control unit 3 to the call type detection unit 13 by a capture synchronization signal line. With the software of the control unit,
When a message is received, a signal to be taken into the call type detection unit 13 is generated, and the content of the received message (maximum 12
The data for one digit of the message (numerical digit) of the twelfth digit from the digit) is sent to the data bus in the control unit as 4-bit parallel data. In the call type detection unit 13, 4-bit parallel data to be compared with the fetched 4-bit parallel data is stored in advance. In this example, 1 (0001) is stored in the call type detection unit 13 as 4-bit parallel data to be compared, and the operation will be described. When the message is received, the 12th digit data of the message is fetched from the control unit 3 to the call type detection unit 13 from the data bus of the control unit 3 in synchronization with the fetch synchronization signal. In the call type detection unit 13, parallel data 1 (0001 ₍₂₎ ) stored in advance is compared, and when the data match, the 1-bit state of the output of the call type detection unit 13 is changed. For example, when the output state before comparison is 0, the output state is changed to 1 if the data match when compared. In addition, the captured data is 1 (0
If it is other than 001 ₍₂₎ ), the state of 1 bit of the output is not changed.

The operation of the call type detection unit 13 in FIG. 1 has been described above. Instead of providing the call type detection unit 13 as hardware, the function of the call type detection unit is executed by software. It is also possible. In this case, the control unit 3 directly outputs one bit of the output of the call type detection unit 13. Figure 2
FIG. 3 is an external view explanatory diagram of the first embodiment of the present invention. In this embodiment, as shown in FIG.
The drive circuit 14 for driving D15 is provided, and the LED 15 is connected to the output of the drive circuit 14. Figure 2
Then, the LED 15 other than the red LED, which has not been used conventionally, is used. For example, using a green LED, L
LCD so that the light from the LED leaks to the CD display unit 12.
The structure is arranged in the case near the display unit 12.
When the caller makes an emergency call, the entire display unit of the message display type wireless call receiver of the user lights up in green. By doing so, the emergency call can be instantly recognized by the user without being influenced by the usage situation of the user. Further, it is possible to control the turning on and off of the LED 14 from the calling source. LED1
It is also possible to provide a plurality of types of emission colors of 5 to turn on the light.

FIG. 3 is a block diagram showing a second embodiment of the present invention. In the figure, 1 to 12 are the same as the conventional components. In this second embodiment, an EL (electroluminescence) display 17 and an EL drive circuit 16 are provided as light emitting elements instead of the LED 15 and the drive circuit 14 of the first embodiment shown in FIG. FIG. 4 is an external view for explaining the second embodiment of FIG. The EL display 17 uses an element that emits a color other than red, and is provided in the case to leak the emitted light to the LCD 12 to illuminate the entire display unit.

[0009]

By implementing the present invention, the intention of the caller can be more surely transmitted to the user. For example, when the user uses the message display type wireless paging receiver embodying the present invention, it is possible to instantly determine whether the call is an urgent call from the calling source or another call, even if the user does not carry it. Since it can be recognized by the display color of the display section, the response to the sender can be promptly achieved. Further, even when the user is busy with work and is busy, the intention of the caller can be instantly known. Therefore, in the case of a call other than an emergency, it is sufficient to confirm the requirement to the caller later. Unlike the conventional case, the caller does not need to confirm the requirement each time it is received, and it becomes possible to concentrate on the business without having to deal with the caller.
