  The audio output control unit 23 controls the timing of turning on the three pulse switches 24a, 24b, and 24c and the timing of switching on / off of the four speaker connection contacts 25a, 25b, 25c, and 25d as follows. By doing so, the destination guidance broadcast and the attention broadcast are not overlapped, and these broadcasts are output from the corresponding speakers in order.

  That is, the audio | voice output control part 23 inputs the driving direction signal which shows the driving direction of a passenger conveyor from the control apparatus 5, and recognizes the driving direction of a passenger conveyor first. Then, during the ascending operation, the first destination guidance broadcast pulse switch 24a and the attention broadcast pulse switch 24c are alternately turned on at a predetermined timing, and the first destination guidance broadcast pulse switch 24a is turned on. Among the four speaker connection contacts 25a, 25b, 25c, and 25d, the contact corresponding to the speaker 15a for outputting the destination guidance broadcast during ascending operation during the time required for broadcasting the destination guidance broadcast during ascending operation A speaker for outputting a caution broadcast among the four speaker connection contacts 25a, 25b, 25c, and 25d for the time required for the caution broadcast after turning on only the caution broadcast pulse switch 24c. Control is performed such that only the contacts 25c and 25d corresponding to 14a and 14b are turned on.

  Specifically, T1 (up) is the required time for the destination guidance broadcast during ascending driving, T2 is the required broadcasting time for the attention broadcasting, and T3 is the interval between the destination guidance broadcasting and the attention broadcasting during ascending driving. Then, the audio output control unit 23 periodically turns on the first destination guidance broadcast pulse switch 24a at intervals of T1 (up) + T2 + 2 × T3. The speaker connection contact 25a corresponding to the speaker 15a for outputting the destination guidance broadcast during the ascending operation from when the first destination guidance broadcast pulse switch 24a is turned on until T1 (up) elapses. Only turn on. As a result, the voice signal of the destination guidance broadcast during the ascending operation is output from the voice generation unit 21 at an interval of T1 (up) + T2 + 2 × T3 and amplified by the amplification unit 22, and this voice signal is passed through the speaker connection contact 25a. Is supplied only to the speaker 15a, and the destination guidance broadcast during the ascending operation is output only from the speaker 15a. Also, the audio output control unit 23 sets the attention broadcast pulse switch 24c to T1 (up) + T2 + 2 × T3 at the timing when T1 (up) + T3 has elapsed since the first destination guidance broadcast pulse switch 24a is turned on. Turns on periodically at intervals. Then, only the speaker connection contacts 25c and 25d corresponding to the speakers 14a and 14b for outputting the attention broadcast are turned on until T2 elapses after the attention broadcast pulse switch 24c is turned on. As a result, the audio signal of the attention broadcast is output from the audio generation unit 21 at a predetermined interval after the destination guidance broadcast ends, and is amplified by the amplifying unit 22, and the audio signal is connected to the speaker connection contacts 25c and 25d. To the speakers 14a and 14b, and a warning broadcast is output from the speakers 14a and 14b.

  Broadcast required time T1 (up) of the destination guidance broadcast during ascending driving is 3.0 seconds, broadcast required time T2 of the attention broadcasting is 17.5 seconds, and interval T3 between the destination guidance broadcasting and the attention broadcasting during ascending driving FIG. 3 shows a time chart when the value is 1.0 second. In the example shown in FIG. 3, the audio output control unit 24 periodically turns on the first destination guidance broadcast pulse switch 24a at intervals of 22.5 seconds, and turns on the first destination guidance broadcast pulse switch 24a. Only the speaker connection contact 25a is turned on until 3.0 seconds elapse after turning on. Accordingly, a destination guidance broadcast such as “It is a escalator going up to the home floor” is output from the speaker 15a at intervals of 22.5 seconds. The audio output control unit 24 periodically turns the attention broadcast pulse switch 24c at intervals of 22.5 seconds at the timing when 4.0 seconds have elapsed since the first destination guidance broadcast pulse switch 24a was turned on. In the period from when the attention broadcast pulse switch 24c is turned on until 17.5 seconds elapses, only the speaker connection contacts 25c and 25d are turned on. As a result, 1.0 seconds after the destination guidance broadcast ends, the speakers 14a and 14b, for example, “If you are using an escalator, please be careful not to get caught in gaps in steps, handrails, etc. ”Is output.

  Further, during the descent operation, the audio output control unit 23 turns on the second destination guidance broadcast pulse switch 24b and the attention broadcast pulse switch 24c alternately at a predetermined timing, and the second destination guidance broadcast. In order to output the destination guidance broadcast during the descent operation among the four speaker connection contacts 25a, 25b, 25c, and 25d during the time required for broadcasting the destination guidance broadcast during the descent operation after the pulse switch 24b is turned on. Only the contact 25b corresponding to the speaker 15b is turned on, and the attention broadcast is required from the four speaker connection contacts 25a, 25b, 25c, 25d after the attention broadcast pulse switch 24c is turned on until the broadcast time required for the attention broadcast. Control is performed such that only the contacts 25c and 25d corresponding to the speakers 14a and 14b for outputting broadcasts are turned on.

  Specifically, T1 (down) is the time required for the destination guidance broadcast during the descent driving, T2 is the time required for the attention broadcasting, and T3 is the interval between the destination guidance broadcast and the attention broadcasting during the ascending driving. At this time, the audio output control unit 23 periodically turns on the second destination guidance broadcast pulse switch 24b at an interval of T1 (down) + T2 + 2 × T3. Then, the speaker connection contact 25b corresponding to the speaker 15b for outputting the destination guidance broadcast during the descent operation from when the second destination guidance broadcast pulse switch 24b is turned on until T1 (down) elapses. Only turn on. As a result, the voice signal of the destination guidance broadcast during the descending operation is output from the voice generation unit 21 at an interval of T1 (down) + T2 + 2 × T3 and amplified by the amplification unit 22, and this voice signal is passed through the speaker connection contact 25b. Is supplied only to the speaker 15b, and the destination guidance broadcast during the ascending operation is output only from the speaker 15b. Also, the audio output control unit 23 sets the attention broadcast pulse switch 24c to T1 (down) + T2 + 2 × T3 at the timing when T1 (down) + T3 has elapsed since the second destination guidance broadcast pulse switch 24b was turned on. Turns on periodically at intervals. Then, only the speaker connection contacts 25c and 25d corresponding to the speakers 14a and 14b for outputting the attention broadcast are turned on until T2 elapses after the attention broadcast pulse switch 24c is turned on. As a result, the audio signal of the attention broadcast is output from the audio generation unit 21 at a predetermined interval after the destination guidance broadcast ends, and is amplified by the amplifying unit 22, and the audio signal is connected to the speaker connection contacts 25c and 25d. To the speakers 14a and 14b, and a warning broadcast is output from the speakers 14a and 14b.

  Broadcast required time T1 (down) of the destination guidance broadcast during the descent operation is 3.5 seconds, broadcast required time T2 of the attention broadcast is 17.5 seconds, and interval T3 between the destination guide broadcast and the warning broadcast during the descent operation FIG. 4 shows a time chart when the value is 1.0 second. In the example shown in FIG. 4, the audio output control unit 24 periodically turns on the second destination guidance broadcast pulse switch 24b at intervals of 23.0 seconds, and turns on the second destination guidance broadcast pulse switch 24b. Only the speaker connection contact 25b is turned on until 3.5 seconds have passed since the power was turned on. Thereby, for example, a destination guidance broadcast such as “It is a wicket going down escalator” is output from the speaker 15b at intervals of 23.0 seconds. Also, the audio output control unit 24 periodically turns the attention broadcast pulse switch 24c at intervals of 23.0 seconds at the timing when 4.5 seconds have elapsed since the second destination guidance broadcast pulse switch 24b was turned on. In the period from when the attention broadcast pulse switch 24c is turned on until 17.5 seconds elapses, only the speaker connection contacts 25c and 25d are turned on. As a result, 1.0 seconds after the destination guidance broadcast ends, the speakers 14a and 14b, for example, “If you are using an escalator, please be careful not to get caught in gaps in steps, handrails, etc. ”Is output.

  As described above in detail with specific examples, in the automatic broadcast apparatus 20 of the present embodiment, the timing at which the audio output control unit 23 turns on the three pulse switches 24a, 24b, and 24c, and the four speakers. By controlling the timing of switching on / off of the connection contacts 25a, 25b, 25c, and 25d, the audio signal of the destination guidance broadcast and the audio signal of the caution broadcast are selectively output from the audio generation unit 21, and the audio After the audio signal output from the generator 21 is amplified by the amplifier 22, it is output from only the corresponding speaker among the four speakers 14a, 14b, 15a, 15b. In other words, the destination guidance broadcast and the caution broadcast can be output from the corresponding speakers so that they do not overlap each other with a single broadcast device. Therefore, it is possible to appropriately output the destination guidance broadcast and the caution broadcast so that the automatic broadcast apparatus 20 itself can be compactly configured to reduce the cost and can be easily heard by the passengers on the passenger conveyor.

  By the way, in the automatic broadcast apparatus 20 of this embodiment, the destination guidance broadcast and the caution broadcast are alternately output from the corresponding speakers. For example, in the vicinity of the speakers 15a and 15b at the timing of outputting the destination guidance broadcast. If it is assumed that the destination guidance broadcast is buried in the surrounding noise and cannot be heard, it is also effective to output the attention broadcast from the speakers 14a and 14b during that time. Conversely, when it is assumed that the noise in the vicinity of the speakers 14a and 14b is large at the timing of outputting the caution broadcast and the caution broadcast is buried in the surrounding noise and cannot be heard, the destination guidance broadcast is transmitted to the speaker during that time. It is also effective to output from 15a and 15b.

  In order to realize such control, for example, as shown in FIG. 5, microphones 16a and 16b (first microphones) for detecting noise in the vicinity of the speakers 15a and 15b and speakers 14a and 14b at appropriate positions on the passenger conveyor. Microphones 17 a and 17 b (second microphones) that detect nearby noise are installed, and the microphones 16 a, 16 b, 17 a, and 17 b are connected to the automatic broadcast device 20. Then, the audio output control unit 23 of the automatic broadcast device 20 determines whether or not the noise level detected by the microphone 16a at the timing of turning on the first destination guidance broadcast pulse switch 24a is equal to or higher than the reference value. In this case, the caution broadcast pulse switch 24c is turned on without turning on the first destination guidance broadcast pulse switch 24a, and the speaker connection contacts 25c and 25d are turned on to transmit the caution broadcast from the speakers 14a and 14b. Is output. Also, the audio output control unit 23 determines whether or not the noise level detected by the microphone 16b at the timing of turning on the second destination guidance broadcast pulse switch 24a is greater than or equal to a reference value. The caution broadcast pulse switch 24c is turned on without turning on the second destination guidance broadcast pulse switch 24b, and the speaker connection contacts 25c and 25d are turned on to output the caution broadcast from the speakers 14a and 14b.

  The audio output control unit 23 determines whether the noise levels detected by the microphones 17a and 17b are both equal to or higher than the reference value at the timing when the attention broadcast pulse switch 24c is turned on, and is detected by the microphones 17a and 17b. When the noise level is higher than the reference value, the first destination guidance broadcast pulse switch 24a is turned on during the ascending operation without turning on the warning broadcast pulse switch 24b, and the speaker connection contact 25a is turned on to output the destination guidance broadcast during the ascending operation from the speaker 15a, and during the descending operation, the second destination guidance broadcast pulse switch 24b is turned on and the speaker connection contact 25b is turned on. The destination guidance broadcast during the descent operation is output from the speaker 15b.

  As described above, when the broadcast to be output is selected according to the ambient noise level, the destination guidance broadcast and the caution broadcast can be output more efficiently and effectively.

  In the above example, when the noise in the vicinity of the speakers 15a and 15b is large when the destination guidance broadcast is output, the caution broadcast is output, and when the noise near the speakers 14a and 14b is high at the timing of outputting the caution broadcast. However, when the destination guidance broadcast is output, the noise near the speakers 15a, 15b is large, or when the attention broadcast is output, the noise near the speakers 14a, 14b is large. In this case, the volume of the destination guidance broadcast output from the speakers 15a and 15b and the caution broadcast output from the speakers 14a and 14b may be increased by increasing the gain of the amplification unit 22, for example.
