【発明の詳細な説明】 (産業上の利用分野) 本発明は、短波帯の電波を使用して文字伝送を行なう
無線印刷電信通信に関し、特に文字データの変復調を行
なう印電装置と、この印電装置を制御し、文字情報の入
出力を行なう制御装置との間における回線の接続手順の
改良に関するものである。Description: TECHNICAL FIELD The present invention relates to wireless printing and telecommunication in which characters are transmitted using radio waves in the short-wave band, and more particularly, to a printing device for modulating and demodulating character data, and this printing device. The present invention relates to an improvement in a connection procedure of a line with a control device which controls an electric device and inputs / outputs character information.
(従来の技術) 例えば陸上海岸局と船舶局の間で行なわれる無線印刷
電信通信は、近年陸上テレックス網との自動接続を中心
とした自動化が進んでいる。(Prior Art) For example, wireless printing and telegraph communication performed between a land shore station and a ship station has recently been automated centering on automatic connection with a land telex network.
従来、自動化海岸局では無線回線が空いていて船舶か
らの着信が可能な場合には、空線信号を送出して船舶へ
これを周知させていた。Conventionally, in an automated coast station, when a wireless line is available and an incoming call from a ship is possible, a skyline signal is sent to inform the ship of this.
(発明が解決しようとする問題点) しかしながら、近年の短波帯周波数の混雑状態は、無
通信時の空線信号が他局に与える影響を無視できないも
のになってきており、新規海岸局においては空線信号の
使用を控える方向にある。(Problems to be Solved by the Invention) However, in the recent congestion state of short-wave band frequencies, the influence of the sky signal during non-communication on other stations has become non-negligible. There is a tendency to refrain from using skyline signals.
このため、船舶局は海岸局の使用状況を知ることな
く、海岸局への発呼を行なうこととなり、海岸局と船舶
局の同時発呼による運用上の障害や、海岸局がスケジュ
ールした定時サービスが妨害されるなどの不都合が生じ
る恐れがある。For this reason, the Vessel Station will call the Coast Station without knowing the usage status of the Coast Station, resulting in operational problems due to simultaneous calls from the Coast Station and the Vessel Station, and scheduled services scheduled by the Coast Station. There is a risk of inconvenience such as being disturbed.
例えば、海岸局と船舶局の同時発呼が発生した場合、
従来の印電装置では制御装置が選択呼び出し要求を出し
た後でも同時発呼のタイミングによっては船舶局からの
呼び出しが優先してしまう可能性があり、制御装置が一
旦選択呼び出しを行なった後に船舶局側の要求に応じる
ようにすることが必要となり、自動化海岸局の設計時の
回線処理が複雑になる。For example, if a simultaneous call from the coast station and the ship station occurs,
In the conventional printing device, even if the control device issues a selective call request, the call from the ship station may be prioritized depending on the timing of simultaneous calls. It is necessary to comply with the request from the station side, which complicates the line processing when designing the automated coast station.
また、海岸局が多数船舶に対する周知サービスなどを
定刻に実施する場合にも一船舶からの選択呼び出しに応
答してしまうとスケジュールを守れない場合が起り得
る。Further, even when the coast station regularly carries out well-known services for a large number of vessels, if the response to the selective call from one vessel may occur, the schedule may not be kept.
そこで本発明は、印電装置の着信動作に対する制御を
制御装置から自由に行なうことができ、空線信号を用い
ないために発生する船舶局からのランダムな選択呼び出
しに対して繁雑な対応処理を用意する必要がなく、安定
した自動通信動作を行なうことのできる無線印刷電信装
置を提供することを目的としている。Therefore, the present invention allows the control device to freely control the incoming call operation of the printing device, and performs a complicated handling process for a random selective call from the ship station that occurs because the skyline signal is not used. It is an object of the present invention to provide a wireless printing and telegraph device that does not need to be prepared and can perform stable automatic communication operation.

32, a receiving line securing signal detecting means 33, a transmitting line securing signal sending means 34, and an acknowledgment signal sending means 35. Of these, the transmission line securing signal transmitting means 34
Is configured to supply a transmission line securing signal to the power-charging device 2 prior to issuing a selective call request from the control device 3. Also, the affirmative response signal sending means 35
Is a receiving line securing signal detecting means for receiving the receiving line securing signal.
When 33 is received, the positive response signal is supplied to the printing apparatus 2 only when the transmission line securing signal has not been transmitted yet. In other words, the control device 3 determines whether to return an affirmative response to this signal or a transmission line securing signal according to the processing status at the time of receiving the receiving line securing signal, and to return the positive response signal and the transmission line securing signal. Any of the securing signals is supplied to the printing apparatus 2 side.

処理を保留させておく。In the printing apparatus 2, when the affirmative response signal detecting means 24 receives the affirmative response signal from the control device 3, the response to the call of the ship station wireless printing and telegraphing device 6 is returned to start the wireless printing and telecommunication. Further, when the transmission line securing signal detecting means 23 receives the receiving line securing signal from the control device 3, the calling of the ship station wireless printing and telegraph device 6 is ignored. In other words, the printing apparatus 2 does not return a response signal to the ship station wireless printing and telegraph apparatus 6 until it receives an affirmative response signal from the control apparatus 3, and suspends the wireless line connection processing.
