Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a selective call receiver with a display function.

(Prior Art) Conventional selective call receivers have made calls by ringing or emitting light, but in recent years new selective call receivers have been developed that can display messages transmitted during a call. In a selective calling system using such a selective calling receiver, in order to make a call at a base station, a selective calling signal consisting of an individual number code and a message code obtained by encoding the transmitted message is created, and this selective calling signal is is inserted into an empty call word of the group to which the selective call receiver to which the call is to be made belongs. The selective call receiver compares the individual number code of the received call signal with its own machine, and if the two match, it notifies the subscriber that there is a call by ringing or flashing, deciphers the message code, and displays the message on the display. to be displayed.

Further, the transmitted message code is stored in a storage device provided within the selective call receiver.

When the subscriber performs a reading operation of the stored message code, the message can be displayed. This procedure will be explained using the flowchart shown in FIG. First, when a subscriber performs a reading operation, the % latest message is displayed and at the same time a time counter is started. If you press the changeover switch here, the next memorized function will operate and the display will disappear.

In this way, each time I wanted to read out the stored Metsu 7-ji, I had to press a changeover switch.

Therefore, in order to search for messages stored in memory, it was necessary to press the changeover switch many times.

(Problem to be Solved by the Invention) As mentioned above, in order to search for a stored message, it is necessary to press a switch each time.
K had to press the toggle button several times to retrieve the message.

SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a selective calling receiver that can eliminate these problems and easily search for messages.

[Structure of the invention]

(Means for Solving the Problem) The present invention provides a method for receiving a selective paging signal transmitted from a base station.
-5 If the individual number code in this selective call signal matches the preset individual number code of the own machine, a call notification is made, and the message code in the selective call signal is displayed on the display.・For selective calling receivers with a message display function that automatically turns off the display if no operation is performed for a certain period of time after the message is displayed, press and hold the changeover switch to change the message displayed on the display. This selective calling receiver is characterized in that the messages to be displayed are switched one after another when the message is displayed.

(Function) According to the present invention, when a changeover switch for changing the message to be displayed is held down for a certain period of time or more, the messages to be displayed are changed one after another at a certain period of time.

This makes it easier to search for stored messages.
There is no need to press the changeover switch many times.

(Example) An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing the configuration of a selective call receiver according to the present invention. In the figure, a receiving circuit 2 is connected to an antenna section 1 that receives a selective calling signal sent from a base station (not shown), and is further connected to a verification circuit 4 via a demodulating circuit 3. This verification circuit 41C is connected to a storage section 5 in which a code unique to this selective calling receiver is stored, and a control section 6 that controls the sound signal and display. Connected to this control section 6 are a drive circuit 7 that generates a sound, a speaker 8, a display driver 9 that displays a received message, a display section 1O1, and a changeover switch 11 that switches the message to be displayed. .

In such a configuration, a selective call signal transmitted from a base station (not shown) is composed of one individual number code and a message code, and this selective call signal is transmitted from the antenna section l.
After being received by the receiving circuit 2 through 1 frequency conversion,
It is demodulated by the demodulation circuit 3 and input to the collation circuit 41C.

The matching circuit 4 matches the sent individual number code with the device-specific code number stored in the storage section 5. When this individual number code and the device-specific code number match and it is confirmed that the device itself is being called,
A sound signal is supplied from the control unit 6 to the speaker 8 via the drive circuit, and a sound is generated. At the same time, it receives and decodes the Metsu 7-ji code sent from the base station (not shown) following the individual number code, stores it in the memory in the verification circuit 4, and displays it via the display driver 9. Part l
Display it on O. Here, a plurality of messages can be stored in the memory in the verification circuit 4, and the message displayed on the display section 10 is
By pressing 1, you can switch one after another.

Here, FIG. 2 shows a flowchart showing a method of displaying a message when performing a reading operation. First, when a message reading operation is performed, the first message among the messages stored in the memory provided in the control section 6 is displayed. In this case, 1. Usually, the newest messages are displayed first. At the same time, a first time counter is started. If the changeover switch 11 is held down from the start of the display, the message display scrolls at predetermined time intervals, and the contents of the second and subsequent messages are displayed one after another on the display section 10. The predetermined time for this scroll display is measured by a first time counter that starts when the display starts. When all messages are displayed in this way, the display is terminated. Further, if the changeover switch is released halfway, a second time counter is started, and if no operation is performed after a certain period of time, the display is ended.

In this way, when the user wants to check the contents of a stored message, it is not necessary to press the changeover switch 11 many times, and the message can be easily searched.

It should be noted that what has been described above is only one embodiment of the present invention, and it goes without saying that various changes can be made without departing from the gist of the present invention.

〔Effect of the invention〕

As described above, in the present invention, if you want to view the contents of a stored message, you can press and hold the changeover switch to change the display. This eliminates the need to press the button, making it easier to search for the contents of a message. In addition, the operation of the selective call receiver can be simplified and the usability can be improved.
