Here, when the signal from the data transfer signal generation unit 62 detects that the electronic telephone directory has been removed during the reception of the dial data from the electronic telephone directory by the signal of the switch SW9 (steps S31 and S32), the CPU 1 determines A signal is sent to the NCU 9 to release the line being captured (step S33). Of course, if it has not been captured with the line, leave it as it is.

On the other hand, when the CPU 1 finishes receiving the dial data, it makes a call.

As described above, in the present embodiment, no call is made when the electronic telephone directory goes off during the reception of the dial data. Further, since a howler sound is sent unless a call is made after the line is captured, in this embodiment, when the electronic telephone directory goes off, not only the call is not made but the captured line is released.

[Sixth Embodiment] In the present embodiment, if the electronic telephone directory comes off while dial data is being received from the electronic telephone directory, the buffer of the main body is cleared.

The configuration of the facsimile of this embodiment is common to FIGS. 2 and 3.

FIG. 14 shows an interface portion between the operation unit 12 and the electronic telephone directory 15 in this embodiment.

FIG. 14 is a block diagram showing the features of the present embodiment. Reference numeral 45 denotes an electronic telephone directory control unit, which is serially (continuously) transmitted by a start signal, a dial signal, an end signal, and a start switch pressed by the user. I do. Reference numeral 82 denotes an interface between the electronic telephone directory and the facsimile. The dial signal from the electronic telephone directory control unit 45 is converted by the PD 11 from an electric signal to an optical signal. PT11 is a light receiving unit on the facsimile main body side, performs photoelectric conversion, and sends it to the operation unit control unit 72.
On the other hand, a control signal from the operation section control section 72 is sent to the electronic telephone directory 45 through PD2 and PT2. The switch SW10 is a switch for monitoring whether or not the electronic telephone directory has been removed from the facsimile main body, and is constituted by a microswitch or a reflection type photosensor. And that information

 FIG. 15 shows a flowchart of the operation unit control unit 72.

First, in step S61, the operation unit control unit SEC72 determines whether or not the electronic telephone directory is attached by the switch SW10. If the electronic telephone directory is removed, the data is not accepted in step S66. On the other hand, if the electronic telephone directory is attached in S61, a dial start signal is detected in step S62. If not detected here, the process returns to step S61 through step S66.
If the start signal is detected in step S62, it is determined whether or not the electronic telephone directory is attached in step S63. If the start signal is attached, the process proceeds to step S64 to detect the end signal. If the end signal is not detected in S64, the data is taken into the buffer 73 in S65, and the process returns to S63. On the other hand, if it has been removed, the contents of the buffer 73 storing the dial information received after the start signal are cleared in step S67. When the end signal is detected, data acquisition is completed in S68, and the process returns to S61.

As described above, by detecting that the electronic telephone directory has been removed from the facsimile body and clearing the dial information that had been transferred up to that point for each buffer, it is ensured that incorrect dialing due to external light will occur. Can be prevented.

[Seventh Embodiment] In this embodiment, when the electronic telephone directory is removed, a signal from the electronic telephone directory is immediately not accepted to prevent a malfunction due to external light. When it is detected that there is a delay, a signal from the electronic telephone directory is accepted after a delay time, so that it is reliably protected from the influence of external light.

The configuration of the facsimile of this embodiment is common to FIGS. 2 and 3. FIG. 17 shows an interface part between the operation unit 12 and the electronic telephone directory 15 in this embodiment. 17, elements that are the same as the elements in FIG. 11 are given the same reference numerals, and descriptions thereof will be omitted. SW9 is a connection monitoring switch for checking whether the switch is attached to or detached from the electronic telephone directory. When the switch is attached, SW9 and SW91 are turned on. Therefore, SW1 to SW7 work effectively, and send a ten-key press signal from the electronic telephone directory to the operation unit control unit 32.
On the other hand, when the electronic telephone directory is removed, the switches 81 and 91 are turned off. Therefore, the conduction of SW1 to SW7
Regardless of the non-conduction, the numeric keypad pressing signal from the electronic telephone directory is not input to the operation unit control unit 32 at all. As a result, when the electronic phone book is removed, the light receiving unit (PT
1 to PT7) malfunction, and an erroneous ten-key press signal (dial signal) is prevented from being input to the operation unit control unit 32.

FIG. 18 is a detailed block diagram of SW9, SW81 and SW91. The monitoring switch SW9 comprises switches 96 and 97 for detecting the attachment and detachment of the electronic telephone directory and the facsimile apparatus. When the electronic telephone directory is attached, the switch is closed. At this time, the inputs of the buffers 93 and 94 become low level, and the outputs are reflected and become high level. Here, reference numeral 95 denotes a delay circuit comprising a capacitor and the like, and the output of the buffer 94 causes a delay with respect to the output of the buffer 93. SW81 and SW91 are analog switches, and C10 and C20 are control signals for the analog switches. This analog switch SW81,91
Is switched on when the control signal is at a high level.
In other words, when the electronic telephone directory is attached, it becomes an analog switch.

FIG. 19 is a timing chart. C1 and C2 are control signals for the analog switches SW81 and 91. An output signal therebelow indicates a conductive / non-conductive state at both ends of the analog switches SW81 and 91. As shown in the timing chart, when the electronic telephone directory is mounted, after a certain delay time, the SW 91 is turned on, the output signal is turned on, and the signal from the card is received. Further, when the electronic telephone directory is removed, the signal is immediately turned off by turning off the SW81, and the signal from the electronic telephone directory is not accepted.

This embodiment is intended to be attached to an electronic phone book.
Even if SW9 is turned on, there is a case where the light is not safely shielded and external light leaks from the gap. According to the present embodiment, even if the SW9 is turned on, a malfunction due to external light can be prevented by not detecting a dial signal until a predetermined delay time.

On the other hand, FIG. 20 shows the operation of FIG. 17 performed by software.

FIG. 21 is a flowchart of the operation unit control unit 32.
In step S81, the operation unit control unit 32 monitors that the electronic telephone directory has been mounted by the connection switch SW9. Then, when it is attached, the timer is set in step S82, and step S82 is performed.
At 83, the timeout is monitored. That is, steps S82 and S8
At 3, the start of optical signal detection is delayed. Then, in step S84, reception of a signal from the electronic telephone directory is started. During the removal of the electronic telephone directory, it is monitored in step S85 that the electronic telephone directory has been removed, and when it has been removed, the signal from the electronic telephone directory is not accepted in step S86.

[Eighth Embodiment] A telephone 100 of this embodiment receives an optical signal from a card dialer 200 to capture a line and transmit a dial signal. Then, if the card dialer 200 comes off while receiving the dial signal from the card dialer 200, the line that is being captured is released.

FIG. 22 shows the configuration of this embodiment. 101 is a CPU which is a control unit of the telephone 100, and 102 is a light receiving unit which receives an optical signal from a card dialer, for example, a photodiode. Reference numeral 103 denotes a microswitch for detecting whether the card dialer 202 has been set to the telephone 100 or not.
Further, a reflection type photo sensor may be used. A dial circuit 104 sends a dial pulse or dial tone to the line 107. A ROM 105 stores a table for converting an optical signal received by the light receiving unit 102 into a dial pulse or a dial tone, a hook switch 106 for capturing and releasing a line, a telephone line 107, and a RAM 108. .

Reference numeral 200 denotes a card dialer.
This is a card dialer that sends a line capture command and a dial number as an optical signal to the light receiving unit 102 in close contact with the light receiving unit 102 so that no external light enters. 201 is a CPU which is a control unit of the card dialer 200, 202 is a light emitting unit such as a light emitting diode, 203
Is a display unit composed of liquid crystal, etc., 204 is an operation unit, 205 is RO
M and 206 are RAMs. The operator operates the numeric keypad and the alphabet key of the operation unit 204 to register the telephone number and name in the RAM 206. When a call is made, the user searches for a telephone number to be called from a telephone number registered in the RAM 206 in advance while operating the search key of the operation unit and looking at the display unit 203.

The operation of this embodiment will be described with reference to FIG. The CPU 101 of the telephone 100 detects by the microswitch 103 that the operator has set the card dialer 200 to a telephone number (step S101). Then, the operator operates the operation unit 204.
Is pressed, the CPU 201 controls the calling unit 202 to transmit a line capture command to the light receiving unit 102 as an optical signal. When the CPU 101 receives the line capture command from the light receiving unit 102 (step S102), the CPU 101 controls the hook switch 106 to capture the line (step S103). After transmitting the line capture command, the CPU 201 transmits a dial signal after a lapse of time necessary for the telephone to capture the line. That is, the dial number displayed on the display unit 203 is encoded with reference to the ROM 205, and the light emitting unit is sequentially driven to emit light.

After capturing the line in step S103, the CPU 101 determines whether the card dialer 200 has been disconnected by the microswitch 103 (step S104) and whether or not the dial signal is transmitted as an optical signal by the light receiving unit 102 (step S105). I do. When the dial signal is detected (step S105), the optical signal is converted into a dial pulse with reference to the ROM 105. Then, it drives the dial circuit 104 to transmit a dial pulse to the line 107. For example, dial number 123
When a call is made to −4567, 1,2,3,4,5,6,7 are coded and sent at predetermined intervals. If the CPU 101 cannot detect the next optical signal within the predetermined period, it determines that reception of all dial numbers has been completed, and ends the light detection by the light receiving unit 102.

On the other hand, if the microswitch 103 detects that the card dialer 200 has come off by the time the reception of all dialed numbers is completed (step S104), C
The PU 101 controls the hook switch and releases the line (step S107). Thereafter, light detection is not performed.

After it is determined that all dial numbers have been received, the line is not released even if the card dialer 200 is removed.

Thus, during dial signal reception, the card dialer 20
When 0 is deviated, light detection is stopped and the line is released, thereby preventing malfunction due to external light. Further, even when a call cannot be made, the line is kept being caught, so that it is possible to prevent the howler sound from being sent.

It should be noted that the detection of the detachment of the card dialer can be detected without using a microswitch, for example, by judging that a signal other than the dial signal and the line capture signal has entered from the light receiving unit 102. .

Ninth Embodiment The telephone according to the ninth embodiment receives a dial signal from a card dialer as an optical signal, decodes and stores the signal, and then captures the line to make a call. On the other hand, if the card dialer comes off before the end of the dial signal reception, the line is not captured.

The configuration of this embodiment is the same as that of FIG. FIG. 24 shows the operation of this embodiment.

When the CPU 101 detects that the card dialer 200 has been set by the microswitch 103 (step S11).
1) The dial number transmitted from the light receiving unit 102 as an optical signal is detected (step S112). Then, the detected dial number is stored in the RAM 108 (step S113). When the CPU 101 determines that the reception of the dial signal has been completed (step S112), the CPU 101 controls the hook switch 106 to capture the line 107, and drives the dial circuit 104 according to the dial number stored in the RAM 108. A dial pulse is transmitted to the line 107 (step S114).

On the other hand, when the micro switch 104 detects that the card dialer 200 has come off before the reception of the dial signal is completed (step S115), the CPU 101 clears the dial number stored in the RAM 108 (step S115). Thereafter, the detection of the dial number and the capture of the line by the light receiving unit 102 are not performed. Therefore, malfunction due to external light can be prevented. Further, since the line is not captured when the card dialer comes off, even if the operator does not respond to the fact that the card dialer has come off, there is no problem such as howler sound being sent.

〔The invention's effect〕

As described above, according to the present invention, when a call is made in response to call information received from a detachably connected call information generation device while a line is seized, call information generation When the device is disconnected and the call is interrupted on the way, it is possible to prevent the line from being continuously invalidated.
