Abstract

PURPOSE:To provide the pager receiver with a dialer function without mis- recognition of display as a dialer to be reception information relating to a call in which the reception information is very easily confirmed after the use of the dialer is finished. CONSTITUTION:Every time a dial tone is generated from a speaker 11 for dial tone, a CPU 1 uses a timer register T of a RAM 7 to measure a predetermined time after the end of the final tone. When a signal representing the presence of a call (coincidence detection signal) is sent from a decoder 4 during generation of a dial tone or during the measurement of said predetermined time, the CPU 1 uses a call tone speaker 14 and an LED 17 after the end of measurement of said predetermined time to start reception notice and allows a display section 20 to display the received information.

2. Description of the Related Art Conventionally, a dial function for generating a dial tone, that is, a DTMF signal tone, etc. is provided, and it corresponds to a contact telephone number received as a message or a telephone number stored in a separately provided telephone number memory. Paging receivers have been proposed which generate a dial tone. By the way, when a paging receiver with a dialer function of this type is called while being used as a dialer, that is, while a dial tone is being generated, only a reception notification is made by blinking an LED (the notification time is usually about 8 seconds). ), The ringing tone is not generated and the received message is not displayed.When the reception memory is to be confirmed, after the dial tone is generated, for example, the read switch is operated to display it on the display. It was But because of this, the LED
The user who notices the call by blinking may mistake the display at that time, that is, the display continuing from the time when the key operation is performed to generate the dial tone, as the received message of this time. Even in the case of not erroneously recognizing, the confirmation of the received message requires the switch operation as described above, which is extremely troublesome in this respect.

[0012] Operation Next, the operation of this embodiment constructed in as above. FIG. 3 is a flowchart showing a receiving process when a call is received. That is, when a signal indicating that there is a call (match detection signal) is sent from the decoder unit 4, the receiving process is started, and first, the received information (call type information and received message) sent. ) Is taken in and set in the buffer register BR (step S1). After that, it is checked whether or not the current reception is a so-called repeat call (a call after the same call is continuously made twice as a measure for poor reception) (step S2), and in the case of a repeat call, the reception process is ended. However, if it is not a repeat call, the process proceeds to step S3. In step S3, it is determined whether 0 is set in the mode register M, that is, whether the mode is the normal mode. When the mode is the normal mode, the display flag D is cleared. It is determined whether or not there is a reception wait (step S4), and when the reception is not received, that is, when a message received in the past is displayed, a number larger by 1 than the value of the pointer P. Is stored in the register W (step S5). On the other hand, the above step S
If a number other than 0 is set in the mode register M in 3 and it is determined that the normal mode is not set, the process proceeds to step S6 and the value of the pointer P itself is set in the register W.
Set to. The value of the pointer P and the like are stored in the register W because the pointer P is used in the next storage process (step S7). Further, the reason why the value of the pointer P is incremented by 1 instead of the value of the pointer P in step S5 is to cope with the shift processing in step S7 described below. When the processing in step S6 or step S5 is completed, or when it is determined in step S4 that reception is waiting, the reception information in the reception information storage unit MM is changed to a row whose row address is one larger. The data is shifted and stored again, and the current reception information set in the buffer register BR with the row with the row address 1 left blank is stored in the row with the row address 1 (step S7).

Next, in step S8, it is judged whether or not the dialing flag G is set, that is, whether or not the dialing tone is being generated. If the dialing tone is being generated, it is ended. After waiting (step S10), when the processing is completed, the dial flag G is lowered, the delay time measuring flag L is set, and the timer register T starts measuring a predetermined time (for example, 2 seconds) (step S11). On the other hand,
When it is determined in step S8 that the dial tone is not being generated, it is determined in step S9 whether or not the delay time measuring flag L is set, that is, after the end of the use as the dialer, a predetermined time is elapsed from the end. It is determined whether (hereinafter, referred to as delay time) has elapsed. When it is determined in step S9 that the delay time has not yet elapsed, and when the process of step S11 is completed, the process proceeds to step S12, and the operation of the reset switch or the elapse of the delay time is waited for, and then, The delay time measuring flag L is lowered (step S13).

When the processing in step S13 is completed or when it is determined in step S9 that the delay time has elapsed and the delay time measuring flag L is down, the process proceeds to step S14. Then, in this step S14, reception notification using the speaker 14 for ringing tone and the LED 17 is started, and the reception information of this time, that is, the reception information storage unit M.
The received information of the row with the row address 1 of M is set in the display buffer 19 and displayed on the display unit 20, the notification flag A and the display flag D are set, and the timer register T starts measuring the elapsed time. After the above processing is completed,
It waits until the reset switch is operated or the timer register T measures a predetermined time (for example, 8 seconds) preset as the notification time (step S15). When the reset switch is operated or when the timer register T measures the notification time, the reception notification is stopped, the notification flag A is lowered, and the timer register T
Is once cleared, and then the measurement is started again (step S16). After the above processing, the operation of the reset switch or the timer register T is waited for measuring a predetermined time (about 30 seconds) as the display time (step S17), and either of these is present. At this time, the post-processing shown in steps S18 to S20, that is, the processing for returning to the state before receiving the call is performed. First, in step S18, it is determined whether or not the data is stored in the register W, and when the data is stored in the register W, that is, the current call displays past reception information or telephone number data. If it is done in the interim, the value of the register W is returned to the pointer P, and the RAM designated by the pointer P
The stored information of No. 7 is set in the display buffer 19, the information is displayed on the display unit 20, the elapsed time is measured by the timer register T, and the content of the register W is further cleared (step S20). Further, when no data is stored in the register W, that is, when the current call is made while waiting for reception, the display flag D
To clear the pointer P and display the current time and the like on the display unit 20 instead of the received information up to that point (step S19). By the processes of steps S19 and S20, the state before the call is received is returned after the notification and display process of the call is completed. The present invention is not limited to the above embodiments, and various modifications can be applied without departing from the present invention.

[0015]

As described in detail above, the present invention is provided with a measuring means for measuring a predetermined time from the end of the final sound each time a dial sound is generated, so that the dial sound is generated or the measuring means is operated. When a call is received during measurement of, the paging receiver with dialer function is arranged to wait for the completion of measurement by the measuring means to display call notification and call information. Even when there is a call during or immediately after that, the operation of confirming the above received information is extremely accurate without misidentifying the display as a dialer as the received information related to the call and after the use as a dialer is completed. This makes it possible to easily provide a paging receiver with a dialer function.
