The voice guidance device 26 includes a handset 31 and a handset base 32 as shown in FIG.

  The handset 31 includes a mouthpiece 33, a mouthpiece 34, and a dial button 35. A microphone is housed inside the mouthpiece 33, and a speaker is housed inside the earpiece 34. The handset 31 is connected to a circuit inside the automatic teller machine 21 by a two-wire cable 36.

  The handset table 32 on the automatic teller machine 21 side is provided with a button 37 that is pressed when the handset 31 is placed. A hook switch 42 and a handset detection switch 43 (see FIG. 3), which will be described later, are arranged below the buttons 37 inside the handset table 32. When the handset 31 is placed on the handset base 32, both the hook switch 42 and the handset detection switch 43 are pressed by the button 37. Therefore, the hook switch 42 and the handset detection switch 43 can detect whether or not the handset 31 is placed on the handset base 32.

  In the embodiment, the hook switch 42 and the handset detection switch 43 are pressed at the same time with one button 37. However, the present invention is not limited to such a structure. For example, a structure in which each button is pressed may be used.

Next, FIG. 3 is a diagram showing a substrate inside the handset 31 and the automatic teller machine 21.
The handset 31 incorporates a control board 51 on which a circuit for amplifying a DTMF signal corresponding to the key of the dial button 35 and outputting it to the automatic teller machine 21 is mounted. The control board 51 is connected to the switch board 41 inside the automatic teller machine 21 by a two-wire cable 36.

  The switch board 41 is arranged below the handset table 32. When the handset 31 is placed on the handset base 32, the hook switch 42 and the handset detection switch 43 are pressed by the button 37 in FIG.

  The handset detection switch 43 (corresponding to the first switch) and the hook switch 42 (corresponding to the second switch) are respectively in an on-hook state where the handset 31 is placed on a predetermined position, that is, on the handset base 32, It is a switch that detects an off-hook condition that is not placed on it.

FIG. 4 is a diagram showing a configuration of a control board 51 built in the handset 31 and a switch board 41 built in the automatic teller machine 21. As shown in FIG.
The control board 51 includes a microphone 52, a DTMF output circuit 53 that outputs a DTMF signal, an amplifier 54, an inverting amplifier 55, and an amplifier 56 that amplify the output signals of the microphone 52 and the DTMF output circuit 53, respectively. The control board 51 includes a connector 57 for connecting to the switch board 41, an amplifier 58 for amplifying an audio signal output from the ATM control unit 71 (see FIG. 5), a microphone 52, and a DTMF output circuit 53. An amplifier 59 for amplifying the output signal is included. The DTMF signal and the like amplified by the amplifier 59 is output to the ATM control unit 71 via the connector 57, the cable 36, and the switch board 41.

The DTMF output circuit 53 outputs a DTMF signal corresponding to the operation signal of the dial button 35.
The output signals of the microphone 52 and the DTMF output circuit 53 are inverted in phase by the inverting amplifier 55 and output to the amplifier 56. The output signals of the microphone 52 and the DTMF output circuit 53 are amplified by the amplifier 54, and the in-phase signal is output to the amplifier 56. The amplifier 56 receives the output signal of the microphone 52 and the DTMF output circuit 53 and the signal whose phase is inverted, so that these signals are canceled out and are not output from the speaker 60 of the handset 31.

  On the other hand, an audio signal input from the ATM control unit 71 via the switch board 41 is amplified by the amplifiers 58, 54 and 56 of the control board 51 and output from the speaker 60 of the handset 31.

  Output signals from the microphone 52 and the DTMF output circuit 53 are amplified by the amplifier 54, further amplified by the amplifier 59, and then output to the switch substrate 41 via the connector 57. As a result, a voice signal or DTMF signal output from the control board 51 is input to the switch board 41. When the handset 31 is in an off-hook state, the voice signal or DTMF signal input from the handset 31 is sent to the ATM control unit 71 (FIG. 5).

  The switch board 41 includes a hook switch 42 and connectors 44 and 45 connected to the hook switch 42. The connector 44 is internally connected to two lines, one line is connected to one terminal of the hook switch 42, and the other line is connected to the connector 45. The connector 45 is also connected to two lines internally, one line is connected to the other terminal of the hook switch 42, and the other line is connected to the connector 44. The connector 45 is connected to the ATM control unit 71 by a two-wire cable 47.

  Accordingly, one line of the two-wire cable 36 is connected in series to the hook switch 42 in the switch board 41, and when the hook switch 42 is in the ON state, the audio signal or DTMF output from the control board 51 A signal is output to the ATM control unit 71.

  On the other hand, when the hook switch 42 is in the OFF state, one line of the two-wire cable 36 is open, so that no audio signal or DTMF signal is output to the ATM control unit 71. The same applies to the audio signal input from the ATM control unit 71. When the hook switch 42 is in the OFF state, the audio signal output from the ATM control unit 71 is not input to the control board 51.

  The handset detection switch 43 is connected to the connector 46 by two lines. The connector 46 is connected to the ATM control unit 71 by, for example, a two-wire cable 48. Therefore, the ATM control unit 71 can determine whether the handset 31 is in the on-hook state or in the off state, depending on whether the handset detection switch 43 is on or off.

The key input unit 86 is a touch panel type input unit and corresponds to the display unit 27 of FIG.

A camera (corresponding to a photographing unit) 87 photographs a user's image. The captured image is stored in the hard disk 83 or the like.
The voice output circuit 88 outputs a voice for guiding the input operation. The output destination of the audio signal output from the audio output circuit 88 is switched to the external speaker 90 or the audio amplifier circuit 91 by the audio switching circuit 89.

  When the handset 31 is in the on-hook state, the audio signal output from the audio output circuit 88 is output to the external speaker 90. When the handset 31 is in the off-hook state, the audio signal output from the audio output circuit 88 is output from the speaker 60 of the handset 31 via the audio amplifier 91 and the hook detection circuit 92. The DTMF signal generated when the user operates the dial button 35 of the handset 31 or the voice input from the microphone of the handset 31 by the user is output to the voice amplifier circuit 91 via the hook detection circuit 92.

  The audio amplifier circuit 91 amplifies the audio signal output from the audio switching circuit 89 and outputs the amplified signal to the hook detection circuit 92, and also outputs the DTMF signal or audio signal input from the handset 31 to the DTMF detection circuit 93.

The DTMF detection circuit 93 outputs a key input value corresponding to the DTMF signal to the IO control unit 94.
The IO control unit 94 outputs the key input value output from the DTMF detection circuit 93 to the main control unit 81. Further, the IO control unit 94 outputs a signal indicating whether or not the handset 31 output from the hook detection circuit 92 is in an off-hook state to the main control unit 81. Further, the IO control unit 94 outputs a signal indicating whether or not the handset 31 detected by the handset detection switch 43 is in an off-hook state to the main control unit 81.

Next, the deposit / withdrawal process in the automatic teller machine 21 will be described with reference to the flowcharts of FIGS. The following processing is executed by the main control unit 81.
When it is detected that the transaction start key displayed on the display unit 27 is operated by the user, the main control unit 81 displays a transaction selection screen (S11 in FIG. 6).

  Next, it is determined whether the handset detection switch 43 is on or off (S12). When the handset detection switch 43 is ON (S12, ON), that is, when the handset 31 is in the on-hook state, the process proceeds to step S13, and it is determined whether or not the key for specifying the transaction on the display unit 27 has been operated. When the transaction is not selected (S13, NO), the process returns to step S12, and the detection of whether the handset detection switch 43 is on or off is repeated.

On the other hand, when the operation of the transaction selection key is detected (S13, YES), the process proceeds to step S14 and normal transaction processing is executed. Description of the contents of normal transaction processing is omitted.
In step S12, when the handset detection switch is turned off, that is, when it is determined that the handset 31 is in an off-hook state (S12, OFF), the user is in the state of picking up the handset 31, so the mode is shifted to the visually impaired transaction mode. To do. In this visually impaired person transaction mode, first, handset current detection is performed (S15). The handset current detection is a process of detecting a current flowing through the cable 36 connecting the handset 31 and the automatic teller machine 21. This current detection is for checking whether or not the cable 36 of the handset 31 is disconnected.

  If it is detected by the handset detection switch 43 that the handset 31 is in the off-hook state and no current is flowing through the cable 36 (S15, NO), it is estimated that the cable 36 is disconnected. To do. The process for determining whether or not the cable 36 is disconnected will be described in detail later.

  When a current is flowing through the cable 36 of the handset 31 (S15, YES), the process proceeds to step S16, and a sound for guiding the transaction selection is output to the speaker 60 of the handset 31. When the user is holding the handset 31, the hook switch 42 is in an on state, so that the voice guiding the selection of the transaction output from the automatic teller machine 21 is transmitted via the hook switch 42. It is output from 31 speakers 60.

  When the user selects a transaction by operating the dial button 35 of the handset 31 in response to the guidance voice, a DTMF signal corresponding to the operated dial button 35 is sent from the handset 31 to the automatic teller machine 21 (hereinafter referred to as an apparatus main body). 21) (S17). In the process of step S17, for example, the main control unit 81 of the apparatus main body 21 recognizes which transaction is selected from the key input value input from the handset 31 and converted by the DTMF detection circuit 93, and the selected transaction. The screen is displayed on the display unit 27.

  Next, handset current detection processing is executed (S18). The handset current detection process in step S18 is the same as the process in step S15, and it is detected whether or not a current is flowing through the cable 36 of the handset 31.

When a current is flowing through the cable 36 of the handset 31 (S18, YES), the process proceeds to step S19, and a voice for guiding the input of the personal identification number is output to the handset 31.
When the user operates the dial button 35 of the handset 31 to input a password (for example, 4 digits), the main control unit 81 recognizes the input password (S20).

Next, the handset current detection process in step S21 of FIG. 7 is executed. The handset current detection process in step S21 is the same as the processes in steps S15 and S18 described above.
If it is detected in step S21 that a current is flowing through the cable 36 of the handset 31 (S21, YES), the process proceeds to step S22, and a voice for guiding the input of the amount is output to the handset 31. This guidance voice is output from the speaker 60 of the handset 31.

  When the user operates the dial button 35 of the handset 31 and inputs an amount, a DTMF signal corresponding to the operated key is output from the handset 31 to the apparatus main body 21. The main control unit 81 recognizes the amount from the key input value output from the IO control unit 94.

  Next, the handset current detection process is executed again (S24). When it is detected that a current is flowing through the cable 36 of the handset 31 (S24, YES), the process proceeds to step S25, where communication with the host computer is performed to check whether the account number, password, etc. are appropriate.

  When it is determined that the transaction is appropriate through communication with the host computer, the bills for the designated amount are counted (S26), and the bills are discharged to the bill insertion / discharge port 25 (S27).

  If no current is detected in the handset current detection process of step S15 or S18 of FIG. 6 or if no current is detected in the handset current detection process of step S21 or S24 of FIG. 7, the process proceeds to step S28. The user is photographed with a camera, and the photographed image is acquired.

  If the handset detection switch 43 detects that the handset 31 is in an off-hook state and it is detected that no current is flowing through the cable 36 of the handset 31, it is assumed that the cable 36 is disconnected, If there is transaction data, log information that associates the transaction data with the image of the person holding the handset 31 and the shooting time is stored in the hard disk 83 or the like (S29). In addition, an alarm is output to notify that the cable 36 is disconnected. At this time, if transaction data is not input, data in which the photographed image is associated with the photographing time is stored in a hard disk or the like. Note that an image may be taken before detecting that no current flows through the cable 36, and the taken image may be stored.

Here, a current detection method of the handset 31 will be described with reference to FIG. The handset control unit in FIG. 8 includes a circuit or the like mounted on the control board 51.
The handset detection switch 43 is, for example, a switch that is turned on when the handset 31 is placed on the handset base 32 and turned off when the handset 31 is not placed on the handset base 32.

  The handset detection switch 43 is connected to the IO control unit 94, and a signal indicating whether the handset detection switch 43 is on or off is output to the main control unit 81 via the IO control unit 94. The main control unit 81 can recognize whether or not the handset 31 is placed on the handset base 32 based on a signal indicating whether the handset detection switch 43 is on or off.

  The hook switch 42 is turned off when the handset 31 is placed on the handset base 32 (when in the on-hook state), and is on when the handset 31 is not placed on the handset base 32 (when in the off-hook state). It is a switch that becomes a state.

  One end of the hook switch 42 is connected to one line of a two-wire cable 36, and the other end of the hook switch 42 is connected to a positive power supply + 24V via resistors 101 and 102. The other wire of the two-wire cable 36 is connected to a negative power supply −24V via the resistor 103.

  When the hook switch 42 is on, the current supplied from the positive power supply + 24V flows through the cable 36 through the resistor 101. Therefore, whether or not the current flows through the cable 36 by detecting the voltage at both ends of the resistor 101. Can be detected. The function of detecting the voltages at both ends of the resistors 101 to 103 and the resistor 101 in FIG. 8 corresponds to the hook detection circuit 92.

  If the handset detection switch 43 detects that the handset 31 is in an off-hook state and if it is detected that current is flowing from the voltage across the resistor 101 to the cable 36, the cable 36 is in a conductive state. It can be judged.

  On the other hand, if the handset detection switch 43 detects that the handset 31 is in an off-hook state and if it is detected that no current is flowing through the cable 36, the cable 36 is disconnected. Can be estimated.

  According to the above-described embodiment, by using two switches, the hook switch 42 and the handset detection switch 43, whether the cable 36 connecting the handset 31 and the apparatus main body 21 is in a conductive state or is disconnected. Can be determined. When the cable 36 is cut or the like, an image of the person who operated the handset 31 is taken, and the image information of the person who cut the cable 36 can be obtained by storing the image.

  In the above-described embodiment, it is determined whether or not the cable 36 is in a conductive state by detecting the current flowing through the cable 36 of the handset 31. However, the present invention is not limited to this detection method. For example, if a response signal is not received within a certain period of time after the guidance sound is output from the apparatus main body 21 to the handset 31, it is assumed that the cable 36 has been disconnected and a user image is taken. May be. Further, when the response signal is not received for a certain time or more, it may be determined that the cable 36 has been disconnected or the like and an alarm may be output. In this case, there is an effect that a current detection circuit using a resistor or the like becomes unnecessary.
