Description

The present invention relates to a radio selective call receiver with a display function,
More specifically, the present invention relates to an improvement in technology for notifying a receiver carrier of whether or not a received message stored in a memory is to be retained when the message is later displayed on a display device.

[Conventional technology]

In recent years, the multi-functioning of the radio selective calling receiver has been advanced, and in addition to a simple calling function, a message display function has been provided which allows a desired command or message to be easily transmitted to a receiver carrier using characters, symbols, or the like. What you have is emerging. A conventional wireless selective call receiver having such a message display function gives a call notification by ringing or light emission when the selective call number in the received signal matches the selective call number assigned to itself in advance. At the same time, a message included in the received signal is detected and stored in the memory, and the message is displayed on a display such as an LCD. Further, when a message reading operation is performed by the operation unit at a later time, the message stored in the memory is read out and redisplayed on the display, so that the message can be reconfirmed. Further, in order to prevent a message stored in the memory from being rewritten by a newly received message, for example, a message protection registration operation is performed by the operation unit while the message is displayed on the display unit. It also has a function of putting the message in a protected state and preventing it from being rewritten. Conventionally, when a message in a protected state is displayed on a display in response to a message display operation, in order to inform the receiver carrier of the fact, conventionally, the memory displayed on the display together with the message content is conventionally used. A specific display such as enclosing a number (a number corresponding to a memory area where the message is stored) with a line is performed. Of course, for messages that no longer require protection, the protection status can be released by performing a message protection release operation on the operation unit.
The memory area it has occupied can be used for storing new messages.

[Problems to be solved by the invention]

The above-described radio selective call receiver, particularly the radio selective call receiver with a display function having a message protection function, can protect a message to be retained, so that when an important message to be confirmed later is received, etc. Was very effective, but it was notified by a method such as enclosing the memory number with a line whether or not it was a protected message, so unless the recipient was conscious of seeing that particular display, There is a problem that it is not possible to recognize whether the message displayed this time is in a protected state or not.

Accordingly, an object of the present invention is to provide a radio selective call receiver with a display function that can notify a receiver carrier of a displayed message in a protected state in a more aggressive and reliable manner. To provide.

[Means for solving the problem]

In order to achieve the above object, the present invention provides a call notification when a selected call number in a received signal matches a selected call number assigned to the self in advance, and stores a message included in the received signal in a memory. The message stored in the memory is read out and displayed on a display in response to a message reading operation of the operation unit, and the message stored in the memory is further responded to a message protection registration operation of the operation unit. In a wireless selective call receiver with a display function for protecting a message from being rewritten by a new message, whether a message read from the memory in response to a message reading operation of the operation unit is protected or not. Determining means for determining whether the message is protected by the determining means. By it is determined, and a control means for operating the drive circuit for driving the sound element.

In a preferred embodiment of the present invention, the sounding element and the driving circuit are also used for calling notification.

[Action]

In the wireless selective call receiver with a display function of the present invention, the message received and stored in the memory is protected by the message protection registration operation of the operation unit, and then read out by the message reading operation of the operation unit and is displayed on the display unit. When displayed, the judging means detects that the read message is protected, and the control means
Preferably, a drive circuit for driving a sounding element used for alerting the call is operated to notify the receiver carrier of the message of the protection state by sounding.

〔Example〕

Next, embodiments of the present invention will be described in detail with reference to the drawings.

Referring to FIG. 2, a radio selective call receiver with a display function according to one embodiment of the present invention includes an antenna 1, a radio unit 2 connected thereto, and a waveform shaping circuit 3 for inputting its output.
And a decoder 4 for inputting its output, and a crystal oscillator 7, an operation unit 8, an EEPROM 9, an LED drive circuit 10, a speaker drive circuit 12, and an LCD drive circuit 14 connected to the decoder 4, and the LED drive circuit 10. LED 11, a speaker 13 connected to a speaker drive circuit 12, and an LCD 15 connected to an LCD drive circuit 14. The decoder 4 includes a control unit 5 and a message storage unit 6, which is a memory for storing messages.

In FIG. 1, a radio signal received by an antenna 1 is amplified and demodulated by a radio unit 2 and then converted into a digital signal readable by a decoder 4 by a waveform shaping circuit 3. The decoder 4 takes in the transmitted digital signal into the control unit 5 while synchronizing with the reference clock generated by the crystal unit 7. The control unit 5 detects whether or not the input call signal contains the same selective call number as its own selective call number stored in the EEPROM 9, and if it contains a message signal to be subsequently inputted. Is detected and stored in the message storage unit 6. Then, the control unit 5 activates the LED drive circuit 10 to blink the LED 11 and / or activates the speaker drive circuit 12 to generate a sound from the speaker 13 to call the receiver carrier. At the same time as notifying, the received message is sent to the LCD drive circuit 14, and the message content is displayed on the LCD 15. Thereafter, when the message protection registration displayed on the LCD 15 is instructed by operating the operation unit 8 including a switch or the like, the control unit 5 sets protection of the corresponding message in the message storage unit 6. So that a new message is not rewritten when it is received.

After that, when the receiver carrier operates the operation unit 8 to instruct the message reading in order to confirm the message stored in the message storage unit 6, the control unit 5 performs a process as shown in FIG. 1, for example. Do. First, a message is read from the message storage unit 6 and sent to the LCD drive circuit 14 to display the message on the LCD 15 (S
1). Next, it is determined whether the message read this time is in a protected state (S2). If the message is in a protected state (YE in S2)
S), the speaker drive circuit 12 is activated to emit a sound from the speaker 13 (S3), and notifies the receiver carrier that the message displayed on the LCD 15 is in a protected state. Note that the sound pattern at this time may be the same as the pattern at the time of call notification, or may be a different pattern for distinction. Further, a specific display may be performed on the LCD 15 as in the related art.

Further, when the message is not in the protected state (NO in S2) and after generating a sound in processing S3, the control unit 5 sends an operation for selecting a message to be displayed next to the operation unit 8
Is determined (S4), and if selected, the process returns to step S1 to display the next message. On the other hand, if it is not selected (NO in S4), the timer for auto reset used to turn off the message display after a preset time is counted (S5), and the set time of the auto reset elapses thereafter. (S
6) If it has not elapsed (NO in S6), the process returns to the determination processing S4 of whether or not the next message display has been selected, and if the set time has elapsed (YES in S6), the LCD drive circuit 14 And the display of the message is deleted from the LCD 15 (S7).

〔The invention's effect〕

As described above, in the wireless selective call receiver with a display function of the present invention, when the message stored in the memory is read out and displayed on the display by the message reading operation of the operation unit, the message is protected. If the message is in the state, the receiver is notified by a sound, so that the receiver can be more positively and reliably informed that the message is in the protected state than before.

Moreover, since the sounding sound indicating that the message is in the protected state is generated using the sounding element provided for alerting the call and the driving circuit thereof, the cost and the size of the receiver are hardly increased.
