1, a tape recorder 102 that is a sub voice recorder, a changeover switch 103 for switching between the two analog tape recorders 101 and 102, and a tape recorder 10.
The audio amplifier 104 amplifies the reproduced signals 1 and 102. The external recording / reproducing device 100 of the ATIS system according to this configuration is a device that records the audio signal from the console 80 in the audio recording device in the external recording / reproducing device 100 and then sends the reproduced signal to the transmitter 90. .

The switch 103 includes two tape recorders 1.
The changeover switch selects 01 or 102, and the changeover operation is controlled by a control signal sent from the console 80 through the control cable 301. The recording / playback control for the voice recorders 101 and 102 is as follows.
Multicore control cables 201 and 4 from console 80
Each of them is remotely controlled by 01. The reproduced signals from the two tape recorders 101 and 102 are amplified by the audio amplifier 104 and then sent to the transmitter 90 via the audio line 601.

The monitoring and control procedure and installation work are complicated, and the work efficiency in maintenance and maintenance is very poor. In addition, since the control of recording / playback / sending to the main recorder and the sub recorder of the analog tape recorder is remotely controlled from the console and is switched by manual selection, the reliability of the device and the information providing device at the airport can be achieved. The required safety is still insufficient.

It is an object of the present invention to provide an external recording / reproducing apparatus for an ATIS system which has reduced costs and man-hours for installation and has improved safety and reliability.

[0006]

In order to achieve the above object, an external recording / reproducing apparatus of an ATIS system configured with a console and a transmitter according to the present invention uses two main and sub digital recorders and two audio signals. Between the selector and the selector that switches the transmission line of the audio signal for recording to one or both of the two digital recorders, the switch that selects and outputs the playback signal of one of the digital recorders, and the console and the transmitter. It has an interface for sending and receiving control signals and a control means for controlling the operation of the digital recorder based on the control signals. The selector receives the audio signal from the console and the interface receives the control signal, and the received control Based on the signal, the control means outputs the audio signal to one of the two digital recorders. One or both of them is recorded, and the interface receives a control signal from the console, reproduces the audio signal recorded by the digital recorder under the control of the control means, and outputs the reproduced audio signal to the transmitter. I am trying.
