Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio selective call receiver with a display function, and more particularly to an improvement in an operation switch of the radio selective call receiver with a display function.

[Prior Art] In this type of conventional radio selective call receiver with a display function,
The operation of stopping the sound, reading and stopping the display information, and the like are performed by manually operating a mechanical switch such as a push switch.

FIG. 4 shows a radio selective call receiver with a display function in which a sound is stopped, display information is read out and stopped, and the like, by manually operating such a mechanical switch.

In FIG. 4, when a selective calling signal is input from the antenna 23, the receiving unit 22 determines whether the selective calling signal is its own signal, a test signal, or another selective calling signal. , A beep sounds to notify the wireless device holder.

When a message signal is added to the selective call signal, the message signal is sent to the signal processing unit 20, where it is stored and simultaneously supplied to the LCD display 19 for display. The LCD display 19 is illuminated by the phototransistor 15
The lamp 18 is turned on only when it is dark due to the photo sensor circuit utilizing. The phototransistor 15 is turned off only when it is dark, and the emitter voltage signal 107 becomes Low level. The signal 107 is inverted by the inverter circuit 29 and supplied to the AND circuit 17 as a signal 111.

At the output terminal 24 of the signal processing unit 20, the signal 108 is configured to be at the Hi level only during the display of the LCD display 19, and when both the signal 111 and the signal 108 are at the Hi level in the AND circuit 17, That is, when the surroundings are dark and the display on the LCD display 19 is being performed, the signal 106 becomes Hi level to turn on the transistor 16 and turn on the lamp 18.
FIG. 5 is a logic table of the signal 111, the signal 108, the signal 106, and the transistor 16.

The stop of the sound and the erasing of the display are realized by turning on the switch 26 and grounding the input terminal 21 of the signal processing unit 20. Some models stop automatically after about 10 seconds from the start of the sound.

When the test signal is received from the antenna 23, the fact that the test signal is received from the receiving unit 22 is transmitted to the signal processing unit 20, and the output terminal 25 of the signal processing unit 20 is set to the Hi level. The terminal 25 is connected to the receiving unit 22, and the receiving unit 22 enters a test mode so that it can receive a common selective calling signal different from its own selective calling signal.

[Problems to be solved by the invention] In the above-mentioned conventional radio selective call receiver with a display function,
To stop the sound and erase the display, the switch 26 must be manually operated.

There is no particular problem when operating one or two normal devices manually, but in operation check or during the manufacturing process, tens to thousands of devices will be handled. Has the problem that it takes a long time.

Also, if you try to operate the
Since the knob shape is made according to the hand of a human, there is a problem that it is not suitable for operation by a machine such as a robot.

[Means for Solving the Problems] The present invention has been made in view of the above-described problems, and has an object to enable an operation check of an operation of stopping a sound and deleting a display without manually operating the operation. The purpose,
In order to achieve this object, in a radio selective calling receiver having a function of displaying received content on a display unit and notifying by sounding and a message display function, a signal processing for detecting and outputting a test signal received and outputting. Unit, a photosensor circuit, and switch means for stopping the notification by the sound and deleting the display, and when a signal is output from the signal processing unit, a signal from the photosensor circuit is output. The switch means is configured to be turned on / off in accordance with an output.

[Example] Hereinafter, an example of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of a radio selective call receiver with a display function according to the present invention.

In FIG. 1, when a selective calling signal is input from the antenna 7, the receiving unit 6 determines whether the selective calling signal is its own signal, a test signal, or another selective calling signal. , A beep sounds to notify the wireless device holder.

If a message signal is added to the selective calling signal, the message signal is sent to the signal processing unit 5, where it is stored and simultaneously supplied to the LCD display 4 for display. The illumination of the LCD display 4 is the phototransistor 1
, The lamp 3 is turned on only when it is dark. The phototransistor 1 is turned off only when it is dark, and the emitter voltage signal 101 becomes Low level. The signal 101 is inverted by the inverter circuit 28 and supplied to the AND circuit 13 as a signal 110.

The output terminal 10 of the signal processing unit 5 is configured so that the signal 102 is at the Hi level only during the display on the LCD display 4, and the AND circuit 13 is used when both the signal 110 and the signal 102 are at the Hi level. That is, when the surroundings are dark and the display on the LCD display 4 is being performed, the signal 104 becomes Hi level to turn on the transistor 2 and turn on the lamp 3.
FIG. 2 is a logic table of the signal 110, the signal 102, the signal 104, and the transistor 2.

When performing operations such as stopping the sound, deleting the display, and calling the memory in the signal processing unit 5 to display the display information on the LCD display 4, the signal processing unit 5 or the transistor 9 is turned on to perform the signal processing. This is realized by grounding the input terminal 12 of the unit 5.

Usually, a plurality of own calling signals can be provided, so one of them is written as a common calling signal in all the receivers, and after receiving this common calling signal, the signal 103 at the terminal 11 is changed to a signal 103 at the terminal 11. It becomes Hi level. In the POCSAG code which calls the common calling signal a test signal, numbers after 2000000 can be used.

When this test signal is received from the antenna 7, the fact that the test signal has been received from the receiving unit 6 is transmitted to the signal processing unit 5. In the signal processing unit 5, the signal 103 at the terminal 11 is set to the Hi level. The signal 103 is supplied to the AND circuit 14.

The signal 101 from the phototransistor 1 is supplied to the AND circuit 14.
And a signal 103 from a terminal 11 of the signal processing unit 5 are supplied. When the light is shining on the phototransistor 1, the signal 101 becomes Hi level. The signal 103 becomes Hi level when the receiver receives the test signal and enters the test mode.
In the test mode, when light is incident on the phototransistor 1, the transistor 9 is turned on instead of the switch 8. When light does not fall on the phototransistor 1, the transistor 9 is turned off. FIG. 3 shows the signal 10
1 is a logic table of signal 103, signal 105, and transistor 9.

The light emitted from the lamp 3 does not leak to the phototransistor 1.

As described above, the present invention has been described with reference to the embodiments. However, various modifications are possible according to the technical concept of the present invention.

[Effects of the Invention] As described above, according to the present invention, in a radio selective calling receiver having a function of displaying received content on a display unit and reporting by sound, a signal for detecting that a test signal has been received is provided. A processing unit and switch means for stopping the sounding notification are provided, and the switch means is controlled to be turned on / off in accordance with the output of the signal processing unit. Thus, the operation can be checked accurately without any operation.
