Abstract

PURPOSE:To solve the problem of a power supply being left ON after use by providing a circuit for detecting the lapse of a predetermined period of time after transmission of data is finished, and a means for disconnecting a power supply part in response to an output signal from the detecting circuit. CONSTITUTION:Data sent from a host device is received by a data sink circuit part 1, is transferred to a CPU, and a specified signal in the data is inputted to a detecting circuit 2. It is detected that the signal thus inputted remains in the same status for at least a preset period of time. Based on the detection, it is detected that the transmission of the data is finished, and a detection signal is outputted to an oscillating circuit part 3 in a power circuit. Upon receiving the signal from the detecting circuit part 2, the oscillating circuit part 3 stops oscillating. By this, a power supply part is turned OFF.

Description

【発明の詳細な説明】 〔産業上の利用分野〕 本発明はプリンタ装置に関し、特にその電源入断に関す
る。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printer device, and particularly to turning on/off the power thereof.

〔従来の技術〕[Conventional technology]

従来、この種のプリンタ装置の電源入断動作は、プリン

っていた。Conventionally, the power on/off operation of this type of printer device has been performed only by a mechanical switch provided on the outside of the printer device.

〔発明が解決しようとする課題〕[Problem to be solved by the invention]

上述した従来の電源入断方式は、機械的なスイッチのみ

Ｎのまま放置してしまうケースが多い。The conventional power on/off method described above uses only a mechanical switch, so it has the disadvantage that it is easy to forget to turn off the power. This is because when printing for a long time (for example, 10 minutes or more), it is rare for the printer to wait on the spot until the printing is finished. Therefore, even though printing has finished, the power is turned off.
There are many cases where it is left as N.

知り、電源回路の発振回路部３に検出信号を出力する。Referring to FIG. 1, data from a host device is received by a data receiving circuit section 1, and the data is transferred to a CPU. The specific data to be transferred is input to the detection circuit 2. The detection circuit 2 detects that the input signal remains in the same state for a preset time or longer. As a result, it knows that the data transmission from the host device has ended, and outputs a detection signal to the oscillation circuit section 3 of the power supply circuit.

発振回路部３は、検知回路部２からの信号を受は発振を
停止する。この事により電源部はＯＦＦ状態になる。The oscillation circuit section 3 stops oscillation upon receiving the signal from the detection circuit section 2. This turns the power supply section off.
