(57) [Abstract] [Purpose] If the command signal from the keyboard to the computer main unit does not perform the following operation within the preset time, the power of the receiver 4 will be automatically cut off and the power will be forgotten. An apparatus for reducing power consumption regardless of the above. [Structure] Signal line a from keyboard 6 of input device
7, and the computer main body 5 by the signal line b8
Connect with. Further, it is characterized in that it is connected to the receiver 4 through the relay 12 from the AC power supply a2.

Description

[Detailed description of the device]

[Industrial application] The present invention automatically shuts off the power of a receiver unless a command signal from a keyboard of an input device to a computer main body is transmitted within a preset time. It is related to the device.

[Prior Art] Conventionally, when using a computer, it is troublesome to save data and turn off the power each time the user leaves a seat such as a telephone or a conference, according to the principle of instantly starting the computer. Generally, when the computer is turned on for a long time, the power of the receiver continues to be turned on, which not only shortens the life of the receiver but is also unreasonable for saving energy.

[Problems to be Solved by the Invention] The present invention is directed to the input device when the power of the receiver is cut off or restarted unless the keyboard or the like of the input device is used within a preset time. It provides a device that can be turned on by hitting the keyboard etc.

[Means for Solving the Problems] In order to solve the above problems, the present invention takes in a signal line a7 from a keyboard 6 or the like of an input device and connects the computer line 5 with a signal line b8. If a key operation of the keyboard 6 of the input device is not performed within a preset time, a means for cutting off the AC power supply b3 of the receiver 4 from the AC power supply a2 through a relay is provided.

[Operation] Since the present invention has taken the above-mentioned means, the receiver automatic power cutoff device 1 has the power supply 9 inside the device. The signal line a7 such as the keyboard 6 of the input device is connected to the computer main body 5 via the receiver automatic power cutoff device 1. The detection circuit 10 detects that a key operation has been performed from a part of the signal line a 7 of the keyboard 6, and starts the timer 11. When the preset timer time has elapsed, the relay 12 is operated and the AC power supply b3 of the receiver 4 is cut off. If the key operation of the keyboard 6 or the like of the input device is performed within the set time of the timer 11, the timer 11 is reset to the initial state.

[Embodiment] FIG. 1 shows an embodiment of connection in which a signal line a7 from a keyboard 6, a mouse, a pen or the like which is an input device is taken in and connected to a computer main body 5 by a signal line b8. Further, the AC power supply a2 is connected to the receiver 4 through the relay 12.

In the computer to which the keyboard 6 or the like of the input device and the image receiver 4 are attached, the time until the interruption can be arbitrarily set to 1 minute, 5 minutes, or 10 minutes. If no key operation is performed within the set time, the power of the receiver 4 is automatically cut off.

At the same time when the power switch of the computer main body 5 is turned on, the receiver 4 also becomes in the operating state. When the operating person stops key input, the power of the receiver 4 is automatically cut off. When the person who operates it again hits the "shift key" on the keyboard 6, the power turns on and the screen rises.If you hit any key other than the "shift key", the power turns on but the key functions also work.

The block diagram of FIG. 2 is an example in implementation, but the receiver automatic power cutoff device 1 can be incorporated in the computer main body 5 or the receiver 4 main body. Further, the invention is applied to a device having the same function instead of the receiver 4. Further, not only the operation of the keyboard 6 of the input device but also a sensor or the like can be substituted.

When there is no SSTV input signal, it can also be used as a monitor on the scan converter side of SSTV.

[Effects of the Invention] As described above, the present invention automatically turns off and on the power supply of the receiver when the computer is in use, and since the screen is not displayed for a long time, the screen burns. It also helps extend the life of the receiver and maintain quality. It also protects VDT, which is harmful to humans, from the screen, and can maintain safety in terms of health. Further, it is economical because the power consumption is reduced regardless of forgetting to turn off the power.
