本発明は電源制御装置に関し、特にＣＲＴ表示装置の電
源の制御に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a power supply control device, and particularly to control of the power supply of a CRT display device.
従来のＣＲＴ表示装置は使用する際使用者が電源を投入
するが電源投入後使用者が何らかの理由でその場を離れ
たり電源の切り忘れがあった場合はそのまま放置される
ということが生じる。When using a conventional CRT display device, the user turns on the power, but if the user leaves the area for some reason after turning on the power or forgets to turn off the power, the device may be left as it is.
上述した従来のＣＲＴ表示装置は使用者が該装置からし
ばらく離れたり使用後電源を切り忘れたりされた場合無
駄な電力を浪費するという欠点がある。The above-described conventional CRT display device has the disadvantage that it wastes power if the user leaves the device for a while or forgets to turn off the power after use.

別信号によりＣＲＴ表示装置の電源を制御する電源制御
装置から構成される。The CRT power control device of the present invention includes a detector for detecting whether a user is near the CRT display device, and a signal from the detector that maintains the same state for a preset time or longer. The CRT display device is composed of a discriminator that determines whether or not the CRT display device is operated, a timer that determines the determination time, and a power supply control device that controls the power supply of the CRT display device based on the determination signal output from the discriminator.
次に、本発明について図面を参照して説明する。 Next, the present invention will be explained with reference to the drawings.

し電源制御装置４へＣＲＴ表示部６へ電源供給を停止す
る信号を出力し、電源制御装置４はこれを受けて電源供
給端子５からＣＲＴ表示部６への電源を停止する。When the main power of the CRT display device is turned on, the detector 1 detects the presence or absence of the user 7. If the user detects the presence, the detector 1 outputs an on signal to the discriminator 2. The discriminator 2 determines whether the on signal of the detector 1 is longer than the discrimination reference time based on the discrimination reference time signal from the timer 3. If the on signal is longer than the discrimination reference time, the discriminator 3 outputs a signal to the power supply control device 4 to supply power from the power supply terminal 5 to the CRT display unit 6. If the ON signal is less than the determination reference time, the discriminator 3 determines that the user 7 is not using the device and outputs a signal to the power supply control device 4 to stop the power supply to the CRT display section 6. In response to this, the power supply from the power supply terminal 5 to the CRT display section 6 is stopped.
以上説明したように本発明はＣＲＴ表示装置の主電源が

止をできる効果がある。As explained above, the present invention has the effect of preventing wasted power by supplying or stopping the power supply to the CRT display section depending on whether or not there is a user after the main power of the CRT display device is turned on. be.
