Abstract

(57) [Abstract] [Purpose] To simplify the operation of reading out a plurality of messages received by the DTMF method and stored in the memory and displaying them on the display. [Composition] Means for reading out and displaying the messages stored in the memory are operated one by one by operating the push switch in order from the newest message, and means for scrolling the entire memory in the old order. The display means is provided so as to be selectively switched. Also, D
When storing a new message by TMF, a means for updating and storing from the old one, a means for clearing a message in the entire memory once, storing a message from the subsequent reception, and inhibiting the memory storage when the entire memory is stored. In this configuration, both storage means are selected by a changeover switch.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a pager display function of a communication device having a message paging function that uses either or both of DTSS and pager functions.

[0002]

[Prior art]

 As a communication method of a communication device, there is a pager communication called a so-called pocket belt in addition to the communication using normal AM / FM / SSB. This is a combination of DTMF (Dual Tone Multi Frequency Signaling) low-frequency high and low tones to call the other station using a signal assigned to a number or an alphabet. The number or alphabet is stored in the other station. Receives subsequent messages depending on the call.

In addition to the pager, there is a DTSS (Dual Tone Squelch System) system, which is a system for opening a squelch using a 3-digit DTMF code. There is a communication method that uses this method to call a specific station or call a specific group simultaneously.

For example, the pager method allows the pager to be used by many people at the same time by reducing the amount of information transmitted as radio waves as much as possible, so that limited radio waves can be effectively used. Therefore, the message transmission / reception after calling the partner station is usually performed in units of 6 characters. As an example of this message, a phrase such as (CALL ME) is used. Therefore, about 10 types of particularly frequently used ones are stored in memory and easily selected and used. For other words and phrases, after setting the communication device to the sending state, operate the ten keys to generate the DTMF signal and send the message. A message is displayed on the display during transmission. If it cannot be expressed in one message phrase, the message is divided into multiple packs of 6 characters and sent.

Most receivers having a message function can use the DTSS and the paging function together. Therefore, if the message reception is set and the DTSS or the paging code matches, the reception circuit opens to display the received message on the display and the latest about 10 packs are stored in the memory. It is rewritten in order from new ones to new messages.

If the message reception is set during a call or when a person is absent, the received message is stored in the memory. To read out and display multiple messages stored in this memory, operate the button switch, etc., and the oldest message is displayed on the display each time you press it. Can be confirmed.

[0007]

[Problems to be solved by the device]

 The messages stored in memory are displayed on the display from the new one one by one each time the button switch is pressed.However, in the case of long messages, they are received and stored in several packs. It is difficult to judge because the order of the words is displayed in reverse, and it is necessary to continue to press the button switches one after another. The present invention aims to improve the above display method.

[0008]

[Means for Solving the Problems]

 To display the stored message, press the button switch, etc. for each display to switch the display from new message to old message, and to display old message from new message by scrolling at a predetermined time. And can be selected by the display mode selection changeover switch.

The received messages are stored in the memory in the order of sequentially rewriting the stored old messages, and the messages to be newly stored in the memory after erasing the previously recorded messages are stored in the entire memory. After that, a means for selecting a function that prohibits the update storage of the memory until the selection of this function is canceled is provided.

[0010]

[Action]

 When the scrolling function is selected for the display means of the received message, the display is switched at an interval of about 2 seconds in the oldest order of the message.

[0011]

【Example】

 1 is a block diagram of an embodiment of a receiver having a message receiving function of the present invention. It will be described with reference to the drawings. In the figure, 1 is an antenna, 2 is a receiving unit, 3 is a low frequency amplifier circuit, 4 is a speaker, 5 is a DTMF receiver, 6 is a CPU, 7 is a display unit, and 8 is a display mode changeover switch.

The DTMF page operation will be described. A DTMF signal generated by a transmitter (not shown) is converted into an analog signal by a DTMF generator. The carrier wave is modulated with this analog signal and transmitted. The signal detected by receiving this signal from the antenna 1 to the receiving unit 2 is digitally converted into an analog signal by the DTMF receiver 6 to obtain numerical or alphabetic data. When this data matches the memory data of the receiver, the pager function synchronizes with the partner station and a call is established with the partner station, and the signal including the subsequent message is accepted.

The following messages are input as shown in FIG. 2 and are sequentially written in the display and the memory. If there is a message stored in the memory, the oldest message is overwritten. This message is stored in each memory at the same time when it is displayed as it is sent in 6-digit characters. If you need only one message, that is fine, but if you want to make multiple messages in a long sentence, naturally multiple memories are required. Also, if you want to view this long message later, you can operate the message read button snatch (not shown) to view the oldest messages in order. Therefore, in a long message, each word is viewed in reverse order, which makes it difficult to judge before and after, which is very inconvenient.

When the message memory is switched to the scroll display by operating the display mode changeover switch 8, the old messages are displayed in order at a predetermined time interval according to the flowchart shown in FIG. This flow chart is set to display every 2 seconds. When the stored message is confirmed, the display mode changeover switch 8 is operated to cancel the scroll display.

Next, claim 2 will be described. FIG. 4 is a flowchart thereof. There is a possibility that a long message is clearly entered, and especially when that message is important, it is necessary to prohibit updating and storing in memory in advance. In this case, first erase the current stored message, store the received messages after that one by one, and when all the memory is stored, update and store the received messages thereafter is prohibited. Hold important messages. The update storage prohibition function and the normal update storage function are selected and switched.

[0016]

[Effect of device]

 The DTMF pager according to the present invention has a function of scrolling the contents stored in the memory and sequentially displaying the stored contents from the oldest one, so that the messages are displayed in the order of reception even if the operator does not select the desired contents As a result, the operability has been improved, and it has become possible to send and receive simple sentences as well as phrases.

Further, since the memory is provided with the update storage means and the update storage prohibition means, and the storage of the memory can be selectively controlled, an important long message is not erased. Since most of the above ideas are processed by software, there are few additional parts and the cost does not increase.
