DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message receiver with an auto dial function.

[0002]

2. Description of the Related Art In recent years, in a radio paging system, not only a paging service by a selective paging signal but also a service of transmitting message information following a selective paging signal and displaying the message information on a display unit of a receiver. It is becoming popular.

[0003] This system is widely used as a means of business communication to outside employees, and as message information,
There are many contact information such as telephone numbers. For this reason, there has been proposed a message receiver with an auto-dial function provided with a dial tone (dial signal tone used in a touch-tone telephone).

[0004]

The above-mentioned message receiver with an auto-dial function generates a dial tone of a contact telephone number received as message information or a telephone number selected from a telephone number memory. By inputting from the mouthpiece of the touch-tone telephone, it is possible to make a call without operating the button of the touch-tone telephone, which is very convenient. However, most of the time you go out, you will need to use a public telephone.In this case, you have to insert coins into the telephone. There is a problem that it does not.

[0005] In addition, the telephone bill when making a telephone call as a business is settled when returning to the office, but there is a problem that it is unclear because it is self-reported. Furthermore, there is a method in which a company provides a telephone card for business use, but it is not actually used because it may be used for private use.

The present invention has been made in view of the above circumstances, and when calling a contact designated by a caller, the call can be made by credit call and private use of the credit call can be prevented. An object of the present invention is to provide a message receiver with an auto dial function.

[0007]

SUMMARY OF THE INVENTION The present invention relates to a message receiver with an auto-dial function, which uses a contact telephone number (or a code designating a telephone number) sent from a caller as message information and a credit call. Control information indicating whether or not the message is accepted is received in the same way as normal message information.
And store it in the message memory.
Out of multiple message information stored in the
Dial signal output with selected message information
When the operation key for commanding
The message information is authorized to use a credit call
Is determined whether or not
Set up a dial number for call
Output the combined dial signal.
You. More specifically, the use of credit calls is allowed
Which outputs a dial signal of a combination of a dial number and the telephone number of the contact for the credit call if, those so as to output a dial signal of only a contact telephone number if it is not allowed credit call It is.

[0008]

With the above arrangement, when calling a contact designated by a caller, or when use of a credit call is permitted, a credit call stored in a memory in advance is used. An auto-dial is performed by a credit call combining a dial number and a designated contact telephone number. Therefore, even when a public telephone is used, it is possible to make a call without inserting coins into the telephone. In addition, since the use of the credit call is controlled by the control information sent as message information from the caller, the private use of the credit call can be prevented.

[0009]

An embodiment of the present invention will be described below with reference to the drawings. First, the external configuration of a message receiver according to the present invention will be described with reference to FIG. In FIG. 1, reference numeral 1 denotes a case, on the front surface of which is provided a display unit 2 constituted by using, for example, a liquid crystal display element. The display unit 2 includes an upper display area 2a and a lower display area 2b, and can display a time, a message, and the like. In addition, a keyboard 3 is located below the display 2 on the front of the case 1.

The numeric keypad 4 is a double function key, and can be switched between a numerical value and an alphabet by a shift key 5 for input. Mode key 6
Designates four modes of (1) a clock mode, (2) a message display mode, (3) a telephone number display mode, and (4) a telephone number writing mode in order by a pressing operation. The memory read key 7 is a key for designating the address of the internal memory and sequentially reading the message information received or stored or the registered name and its telephone number. The memory read key 7 is also used as an address designation key when writing a telephone number in the memory. The transmission key 8 is a key for starting transmission of a designated telephone number by a dial tone. The message receiving function on / off switch 9 is a switch for turning on / off only the message receiving function.

The display unit 2 has a mode key
According to 6, (1) the current time is displayed in the upper display area 2a when the clock mode is specified, and (2) the message arrival time and the lower display in the upper display area 2a when the message display mode is specified. The call number, call type information and received message of the memory are displayed in area 2b. (3) When the telephone number display mode is designated, the upper display area 2
The name read from the memory is displayed at a, and the registered telephone number read from the memory is displayed at the lower display area 2b. (Four)
When the telephone number writing mode is designated, the name input by a key in the upper display area 2a and the telephone number set by the ten keys 4 in the lower display area 2b are displayed.

Next, an electronic circuit provided in the case 1 will be described with reference to FIG. In the figure, reference numeral 11 denotes an antenna which receives a radio wave output from a radio base of a message service company and inputs the radio wave to a receiving unit 12. As a radio wave output from the radio base of the message service company, for example, a 280 MHz FM radio wave is used. This FM radio wave is modulated by the FSK signal (NRZ) method,
It contains information on a bit rate of 512 bits / sec.

The receiving section 12 includes a selection circuit for selecting a 280 MHz signal, a demodulation circuit for demodulating an FSK signal, and the like. The FSK FM signal is demodulated to “0”,
The signal is output as “1” to the decoder unit 13. The decoder unit 13 is connected to an ID-ROM 14 that stores its own identification code. The decoder unit 13 analyzes the data by, for example, the POCSAG method, determines whether or not it is its own calling number by referring to the ID-ROM 14, and when it is its own calling number,
The CPU 15 issues a reception fetch command for receiving call type information associated with the call number and message data following the call number.
Output to The CPU 15 includes a key input unit 16 and a RAM.
The display unit 2 is connected via the display buffer 18 together with the connection 17.

The key input section 16 inputs a signal corresponding to the operation of each key provided on the keyboard 3 to the CPU 15. The RAM 17 is a memory for storing a message from the caller and also for storing a plurality of telephone numbers, credit telephone numbers (dial numbers for credit calls), etc., which are input by the ten keys 4. It will be described later. Further, the CPU 15 is provided with an LED drive section 21, a sound signal generation section 22, a DTMF signal sound (Double).
Tone Multi Frequency: dial signal tone used in a touch-tone telephone) generating unit 23 and a buffer 24 for temporarily storing dial data are connected. And LE
The LED 10 is connected to the D drive unit 21, and the speaker 25 is connected to the sound signal generation unit 22 and the DTMF signal sound generation unit 23. The speaker 25 is provided, for example, on the back side of the case 1.

When the ringing signal generator 22 receives a call from a caller, it drives a speaker 25 in accordance with a command from the CPU 15 to notify an incoming call, and the DTMF signal generator 23 is set in a buffer 24. A DTMF signal is generated based on the dial data thus generated, and the speaker 25 is driven to generate a dial sound. After the end of the dialing, an end signal is sent from the DTMF signal tone generator 23 to the CPU 15. The above CP
U15 controls each part according to the key operation signal, and determines the control information indicating whether or not to use the credit call sent from the caller together with the contact information. When the use of the credit call is permitted, Only the operation of reading the credit call telephone number from the RAM 17 and generating a dial tone is performed.

Next, an outline of the pox sag method used in the message receiver will be described. FIG.
(D) is a data configuration diagram of the poxag method. FIG.
(A) shows the entire transmission signal format. In the Poxag system, a preamble signal A in which 576 bits of bit data successively follows 101010, and a plurality of batch signals B, C,. . The preamble signal is a signal for causing the message receiver to recognize that data will be sent from now on and for achieving bit synchronization. The decoder unit 13 detects this preamble signal and prepares for reception of the subsequent batch data.

FIG. 3B shows a batch format of the batch data. In this batch format, there is first a one-word synchronization code SC, followed by eight frames CD1 to CD8, each consisting of two codewords. Each code word has a 32-bit configuration, and the code word includes an address code word and a message code word.

FIGS. 3C and 3D show the structures of an address code word and a message code word, respectively. FIG. 3C shows an address code word, which has a message flag at the head, an address bit, a function bit, a BCH parity bit, and an even parity bit.

The message flag is a flag for discriminating whether the code word is an address code word or a message code word. When the code flag is "0", the message code word is represented. I have. 2 bits after message flag to 19
The bit is an address bit representing an address code, and this address code corresponds to the above-mentioned call number. Further, there are two function bits after this. These are bits for indicating a display mode and a sound mode. For example, there are four types of functions of "00", "01", "10", and "11". This function information can be input by the caller with a touch-tone telephone by contracting with the message company, and can be used for identification of the caller.

In the wireless paging system, an error may occur in received data, for example, in an address code. Especially when the reception condition is bad,
The demodulation of the FSK signal is not complete, and an error occurs. In order to correct this, the BCH parity is provided in bits 22 to 31 in the Poxag scheme. After that,
An even parity bit is provided. The even parity indicates whether the total number of bits whose first to last bits represent the number of “1” is odd or even.

In the case of the message code word shown in FIG. 3D, a message bit is added after the message flag. This is in addition to the message from the caller, for example a telephone number and other information. Further, as in the case of the address code word, BCH parity and even parity data are added to form a message code word.

FIG. 4 shows the details of the RAM 17 in FIG. In the RAM 17, a buffer register BU for temporarily storing a received message, a mode counter M for specifying a mode, timers T1 and T2, a pointer P for specifying an address of a specific area in the RAM 17, a clock register 30, and a received message are stored. There are provided a FIFO message register 31, a telephone number storage memory 32 for storing telephone numbers inputted from the key input unit 16, and a credit call memory 33 for storing credit call telephone numbers.

The mode counter M has a clock mode when the count value is "0", a message display mode when the count value is "1", a telephone number display mode when the count value is "2", and a telephone number writing mode when the count value is "3". specify. Pointer P is
This is for designating each address of the clock register 30, the message register section 31, and the telephone number storage memory 32. The timer T1 controls the notification time of the notification of the incoming call by the LED 10 and the speaker 25 when receiving the calling signal from the caller, and measures, for example, the lapse of time of 8 seconds. The timer T2 is for controlling the display time of the received message when the above-mentioned calling signal is received, and measures, for example, the elapse of 30 seconds. The clock register 30 is for clocking the current time.
The address is provided at the address (relative address).

Further, the message register section 31 has addresses 1 to
It is provided at the address of address 30, and stores the call type information and the arrival time together with the received message at each address. The message register section 31 is a FIFO
When the received message once stored in the buffer register BU is written to the register at the first address, the storage information of each register is sequentially shifted to the register at the next address. The message held in the address register is extruded and disappears.

The telephone number storage memory 32 has a
It is provided at addresses 50 to 50, and key input section in write mode
The phone number and name entered from 16 are stored in each address. In this case, the above time register 3
0, message register part 31, telephone number storage memory part 3
Each address of 2 is designated by the pointer P. Further, the credit call memory number 33 is written with a credit call telephone number in which a stop code for stopping generation of dial sound for a predetermined time for a second dial tone or the like is inserted at a predetermined position. The telephone number can be written in a confidential manner in advance on the side that lends the message receiver to an employee or the like. For example, after the write mode is designated by the mode key 6, the address of the credit call memory section 33 is designated by using the password, and thereafter, the credit call telephone number can be written by the ten keys 4.

Next, the operation of the above embodiment will be described with reference to the flowchart of FIG. The CPU 15 performs (1) when there is a call from the caller, (2) when performing the time counting process,
(3) When a key operation is performed, the processing shown in the flowchart of FIG. 5 is executed. Assuming that the call from the caller is received by the receiving unit 12 and the call is its own call number, a receiving / acquisition command is sent from the decoder unit 13 to the CPU 15. This causes an incoming interrupt,
The CPU 15 proceeds to step A2 from the HALT state in step A1 in FIG. It is temporarily stored in the BU. The message information sent from the caller includes control information indicating whether a credit call can be used together with the telephone number of the contact. As the control information, for example, two consecutive hexadecimal F-codes representing a left parenthesis “((” is used. That is, the double parenthesis is used as a credit call permission code, and is used in a received message. The use of the credit call is permitted only when this includes the permission code.

Then, the information fetched into the buffer register BU is transferred to the message register section 31 and stored at the address 1 (step A3). At this time, the previous information held at each address of the message register unit 31 is sequentially shifted to the next address. That is, the latest received information is always written and held at the address 1 of the message register unit 31. Next, whether or not you are dialing,
That is, the DTMF signal tone generator 23 determines whether or not a dial operation is being performed (step A4). If the dial operation is not being performed, an operation command is sent from the CPU 15 to the sound signal generator 22 and the speaker 25 is set to a predetermined It is driven at the frequency to notify the incoming call (step A5). More CPU
An operation command is sent from the LED 15 to the LED driving unit 21, the LED 10 is driven to emit light, and an incoming call notification is made by light (step A6). In this case, during dialing, the speaker 25 is not driven, only the LED 10 is driven to emit light, and an incoming call is notified. At this time, R for controlling the notification time of the incoming call is set.
The timer T1 in the AM 17 is set (step A7).
).

Next, it is determined whether or not the set mode at this time is the watch mode, that is, whether or not the count value of the mode counter M in the RAM 17 is "0" (step A8). Return to HALT state. If the clock mode is designated, the count value of the mode counter M is set to "+1" to set the message display mode (step A9), and the pointer P
Is set to "1" (step A10). In this state, C
The PU 15 reads out the contents of the address 1 of the message register unit 31 indicated by the pointer P, outputs it to the display buffer 18, and displays it on the display unit 2 (step A11). In this case, the arrival time is displayed in the upper display area 2a of the display unit 2, and the call type information and the message are displayed in the lower display area 2b. At this time, if the permission code “((” is included in the message, the message is displayed as it is. Therefore, the user can easily confirm whether or not to make a credit call from the displayed content of the message.
When the above display processing is performed, a timer T2 for controlling the message display time is set (step A12).
The process returns to the HALT state in step A1.

If a timer interrupt occurs in this state, the process proceeds to step A13 to perform a timer process. The timer interrupt occurs at, for example, one second intervals, whereby the timer information in the clock register 30 is incremented by "+1". Next, it is determined whether or not the timer T1 is set (step A14). If the timer T1 is set, the count value of the timer T1 is incremented by "+1" (step A15). Then, it is determined whether or not the measured value of the timer T1 has reached a set value, 8 seconds in this embodiment, and if it has not reached 8 seconds, it is determined whether or not the timer T2 has been set (step A18).

If it is determined in step A14 that the timer T1 has not been set, the process immediately proceeds to step A18 without performing the measurement process of the timer T1, and determines the set state of the timer T2. When the timer T2 is set, the count value of the timer T2 is set to "+1".
After (Step A19), it is determined whether or not the measured value has reached a set value, in this embodiment, 30 seconds (Step A2).
0) If the time has not reached 30 seconds, the HAL of step A1
Return to the T state.

The above timer interrupt is performed at regular intervals, so that the timer T1 times out, that is, 8 times.
When the elapsed time of seconds is measured, a drive stop command is sent from the CPU 15 to the LED drive unit 21 and the sound signal generation unit 22, and LE
The incoming notification operation by D10 and the speaker 25 is stopped (step A17). Further, thereafter, when the timer T2 times out, that is, when the elapsed time of 30 seconds is measured, the CPU
From 15, "0" is set in the mode counter M to designate the clock mode, and "0" is set in the pointer P (step A21). When "0" is set in the pointer P, the current time information is read out from the clock register 30 at address 0 to the display buffer 18 via the CPU 15, and
As shown in FIG. 1, it is displayed in the upper display area 2a of the display unit 2 (step A22). If the timer T2 has not been set, the process proceeds directly from step A18 to step A18.
Proceeding to 22, the above-mentioned present time is displayed.

When a call is received from the caller as described above, an incoming call is notified by the LED 10 and the speaker 25 for 8 seconds, a received message is displayed on the display section 2 for 30 seconds, and thereafter, the mode returns to the normal clock mode. To display the current time.

The key operation signal from the key input section 16 is C
When input to the PU 15, the process proceeds from the HALT state of step A1 to step A23, where key processing is performed. Less than,
Details of this key processing will be described with reference to the flowcharts of FIGS. In order to display the message information held in the message register section 31 in the RAM 17 on the display section 2, the message display mode is designated by the mode key 6, or the reading key is read in the clock mode.
Operate 7. When the above key operation is performed, it is determined in step B1 whether the operation key is the mode key 6. If the operation key is the mode key 6, the count value of the mode counter M is incremented by "+1" (step B2). It is determined whether or not the mode is the message display mode (mode counter M = 1) (step B3). If the mode is the message display mode, the pointer P is set to "1" (step B4) and the timer T2 starts counting. (Step B5
).

Then, the storage information of the address specified by the pointer P from the RAM 17, in this case, the information stored at the address 1, that is, the call type information, the message,
The incoming time is read and displayed on the display unit 2 (step B6
). That is, when the message display mode is designated by the mode key 6, first, the latest message information stored at the address 1 of the message register section 31 is displayed on the display section 2.

When the read key 7 is operated in the clock mode, the process proceeds to step B7 via step B1 to determine whether or not the operation key is the read key 7. In this case, the read key 7 is operated. Is being operated,
Further, in step B8, it is determined whether or not the watch mode (M = 0). At this time, since the clock mode is specified, the content of the mode counter M is set to "+1" to specify the message display mode (step B9), and the pointer P is set to "1" (step B10). Thereafter, the above step B5 (start the timer T2)
Then, the process proceeds to step B6, where the message information stored in the address 1 of the message register unit 31 is displayed on the display unit 2 as described above.

To display the next message, the read key 7 is displayed while the message information is displayed.
Operate. When the read key 7 is operated, the flow advances to step B11 via steps B1, B7 and B8, and it is determined whether or not the mode is the message display mode. In this case, since the message display mode is set, the pointer P is moved to “+”.
After "1" (step B12), it is determined whether or not the value has reached "31" (step B13). If the value of the pointer P has not reached "31", the process proceeds to step B6 via step B5, and the above-described message display processing is performed. That is, the information stored in the message register unit 31 specified by the value of the pointer P is read out and displayed on the display unit.
Displayed in 2.

In the same manner, each time the read key 7 is operated, the value of the pointer P is incremented by "+1", the designated address for the message register section 31 is updated, and the message information stored in the message register section 31 is updated. They are sequentially read out and displayed on the display unit 2. Then, the read key 7
The value of the pointer P is changed by the operation of
Becomes "31" beyond the last address (address 30), this state is detected in step B13 and the pointer P becomes "1".
Is set. As a result, the designated address of the message register section 31 returns to address 1, and the stored information is displayed on the display section 2. By operating the read key 7 as described above, the information stored in the message register section 31 is sequentially displayed on the display section 2. If no key operation is performed in this message display state, the timer T2 sets the timer to 30 minutes. When the seconds are counted, the mode returns to the clock mode.

The telephone number storage memory of the RAM 17
When the telephone number stored in 32 is displayed on the display section 2, the telephone number display mode is designated by the mode key 6. When the mode key 6 is operated, steps B1, B2
Then, the process goes to step B3 to determine whether or not the mode is the message display mode. In this case, since the telephone number display mode has been designated, the determination result in step B3 is NO, and
Proceeding to step B15, it is determined whether the telephone number display mode or the telephone number storage mode has been designated.

When the telephone number display mode or the telephone number storage mode is designated, the pointer P is set to "31".
Is set, the process proceeds from step B5 to step B6 to perform display processing. That is, the address "31" of the telephone number storage memory unit 32 is designated by the pointer P, and the name and the telephone number stored at the address "31" are stored in the CPU.
The name is read out to the display buffer 18 via the display 15, and the name is displayed in the upper display area 2a of the display unit 2, and the telephone number is displayed in the lower display area 2b.

When reading and displaying another telephone number stored in the telephone number storage memory section 32,
The read key 7 is operated in this state. This read key 7
Is operated, the flow advances to step B11 via steps B1, B7 and B8, and it is determined whether or not the mode is the message display mode. In this case, it is not the message display mode,
The result of the determination is NO, the process proceeds to step B17, and the pointer P is incremented by "+1". Next, the value of the pointer P becomes “5”.
1 ”, that is, a telephone number storage memory unit.
It is determined whether or not the final address of 32 has been exceeded. If the final address has not been exceeded, the flow advances to step B6 via step B5.
In this step B6, the information stored in the telephone number storage memory section 32 whose address is designated by the value of the pointer P is read out and displayed on the display section 2. As described above, in the telephone number display mode, the value of the pointer P is incremented by "1" each time the read key 7 is operated, and the name and telephone number stored in the telephone number storage memory section 32 are sequentially read. It is displayed on the display unit 2.

When the value of the pointer P reaches "51" beyond the last address (address 50) of the telephone number storage memory 32 by operating the read key 7, the state is detected in step B19. The value of “31” is set in the pointer P. As a result, the address designation of the telephone number storage memory unit 32 returns to the first address, and the stored information is displayed on the display unit 2.
Will be displayed.

In the telephone number writing mode, information stored in the telephone number storage memory section 32 is displayed on the display section 2 in the same manner as in the telephone number display mode. After correction or rewriting, it can be written in the corresponding address of the telephone number storage memory unit 32.

When the mode key 6 is operated to switch from the message display mode or the telephone number display mode to the clock mode, steps B3 and B are executed.
The determination results in 15 are all NO, and the process proceeds to step B20, where "0" is set in the pointer P. Then timer T
2 is turned off (step B21), and the process returns to the display processing of step B6. As a result, the clock register 30 at address 0 is designated by the pointer P, and the clock information is read out to the display buffer 18 and displayed on the display unit 2.

However, when performing auto dialing,
The message display mode or the telephone number display mode is designated, and the transmission key 8 is operated while the number to be called is displayed on the display section 2. When this send key 8 is operated,
The result of determination at steps B1 and B7 in FIG. 6 is NO, and the process proceeds to step B22 in FIG.
Is determined. If the operation key is the transmission key 8, it is further determined in step B23 whether or not the mode is the message display mode. When the message display mode is designated, it is further determined whether or not the permission code is included in the message. If the authorization code is included,
The credit call telephone number stored in the credit call memory unit 33 from the RAM 17 is read out by the CPU 15, combined with the telephone number displayed on the display unit 2 and set in the buffer 24 (step B25).

Next, a DTMF signal tone generator from the CPU 15
The operation command is sent to the DTMF signal generator 23, and the DTMF signal tone generator 23 operates to generate a DTMF signal according to the telephone number set in the buffer 24 to drive the speaker 25 (step B26). When the dial operation ends, the DTMF signal tone generator 23 outputs an end signal to the CPU 15.

On the other hand, if it is determined in step B24 that the permission code is not included in the message, the process proceeds to step B28. In step B28, the display unit
2 is set in the buffer 24, and then an operation command is sent from the CPU 15 to the DTMF signal tone generator 23. Thereby, the DTMF signal sound generation unit 23
Operates to generate a DTMF signal in accordance with the telephone number set in the buffer 24 to drive the speaker 25 (step B26). When the transmission key 8 is operated in the message display mode as described above, a dial operation by a credit call is performed when the permission code is included in the displayed message, and a credit call is performed when the permission code is not included in the display message. Is prohibited, and a normal dial operation is performed.

If it is determined in step B23 that the mode is not the message display mode, the process proceeds to step B23.
In step 27, it is determined whether the mode is the telephone number display mode. If the mode is the telephone number display mode, the process proceeds to step B28. In step B28, the telephone number read from the telephone number storage memory unit 32 and displayed on the display unit 2 at that time is buffered.
The operation command is sent from the CPU 15 to the DTMF signal tone generator 23. As a result, the DTMF signal tone generator 23 operates to generate a DTMF signal according to the telephone number set in the buffer 24 to drive the speaker 25 (step B26).

When the telephone number display mode is designated as described above, the use of the credit call is prohibited, and a normal dial operation is performed. If it is determined in step B27 that the current mode is not the telephone number display mode, the dial operation is not performed and the process returns to step A1 in FIG.

[0049] In addition, a numeric keypad 4,
When the shift key 5 or the like is operated, steps B1, B7
, B22 are all NO, and step B29
The process corresponding to the operation key is executed.

In the above embodiment, the contact information received as the message is not limited to the telephone number, but may be information specifying the address of the telephone number storage memory unit 32. Therefore, in this case, the address in the telephone number storage memory unit 32 is designated by the code in the message, the telephone number is read, and a credit call or a normal dial operation is performed depending on the presence or absence of the permission code.

FIG. 8 shows details of the transmission key processing in this case. Step numbers that are the same as those in FIG. 7 indicate the same processing. When the transmission key 8 is operated in the message display mode, the process proceeds to step B30 via step B23, and the information selected to display the address of the telephone number storage memory section 32 is included. Is determined. If the address designation information is included, the telephone number storage memory section 32 is executed in step B31.
Then, the telephone number is read from the address corresponding to the above, stored in the buffer in the CPU 15, and then proceeds to step B24. If the address designation information is not included, the procedure directly proceeds to step B24.

At step B24, it is determined whether or not the permission code is included in the message selected for display. If the authorization code is included, the credit call telephone number is read from the credit call memory unit 33. If the telephone number is stored in the buffer in the CPU 15, the telephone number is stored. Is set in the buffer 24 (step B25), and in the next step B26, a dial tone is output in accordance with the combined telephone number. That is, the dial sound of the credit call is output. If it is determined in step B24 that the permission code is not included, the process proceeds to step B28. If the telephone number is stored in the buffer in the CPU 15, the telephone number is not stored. The telephone number in the middle is set in the buffer 24, and a dial tone according to the set telephone number is output in step B26. That is, the dial tone of the normal call is output only by the telephone number.

When the transmission key 8 is operated in the telephone number display mode, the operation proceeds to step B28 via steps B23 and B27 as already described with reference to FIG. The telephone number read from 32 and displayed on the display unit 2 is set in the buffer 24, and a dial tone according to the set telephone number is output in step B26.

In the above embodiment, the control information sent from the caller together with the contact information is displayed on the display unit as it is to indicate whether or not the credit call can be used. The information may be determined and the display may be flushed when a credit call is permitted.
