Conventionally, in this type of power-saving data processing device, a power-saving time limit is set for power saving, and if no data is input during this time period, the operation mode automatically saves power. While switching to the mode, when data is input from an input means such as a keyboard, a numeric keypad, a mouse, the mode returns to the normal operation mode.

Another technique for saving power when an operator leaves the seat is disclosed in, for example, Japanese Patent Laid-Open No. 4-291612.
And Japanese Patent Laid-Open No. 5-66863. In the devices described in these two publications, both
The device is equipped with a proximity sensor that detects the presence / absence of an operator in a non-contact manner. When the operator (worker) is absent, the proximity sensor detects that the power saving mode is immediately activated, and the file device and backlight Power supply to input devices such as a keyboard and the like, and others is cut off.

[0005]

The above-described conventional power-saving data processing device has a problem that the power saving is insufficient because the power is normally supplied during the power-saving time period monitoring. Furthermore, if data input is interrupted due to thinking work, office work, etc. while referring to the display image displayed on the screen, the power saving mode is automatically switched to when the power saving time monitoring reaches the time limit, and the reference is made. There is a problem that the displayed image disappears.

Further, in the device described in the above-mentioned publication, when a person is near the device, the person is sensed and the normal power is supplied to the device, so that power saving is not achieved, which is a problem in practical use. There is a point.

An object of the present invention is to solve the above problems and
It is an object of the present invention to further promote power saving and provide a user-friendly power saving data processing device.

Further, for the power saving function, the input unit 1 is provided with the touch sensor 12 and the proximity sensor 13, the display unit 2 is provided with the proximity sensor 22, and the control unit 3 is set to the power saving mode. The power saving time limit unit 31 is further provided, and the display switch 4 and the power saving switch 5 are further provided. These outputs are inputted to the control determination unit 6, and the control determination unit 6 is made to the power distribution unit by the input information. 7 is controlled to cut off the supply of extra power.

The touch sensor 12 is provided according to the present invention. For example, as shown in FIG. 2, the touch sensor 12 is provided on the front side edge portion of the input means 11 such as a keyboard, and, for example, on a mouse. In this case, it is provided in a portion such as the front side surface where a hand or a finger touches, and when the hand or the finger touches it, this is detected, and the power distribution unit 7 is detected via the control determination unit 6.
Immediately instructs the power supply in the normal operation mode.

As shown in FIG. 2, the proximity sensors 13 and 22 detect the presence of an operator who operates the device by sensing infrared rays radiated from the human body, for example, on the front surface, and display it. When both the switch 4 and the power saving switch 5 are in the “OFF” state, the power supply distribution unit 7 is instructed to supply power in the normal operation mode via the control determination unit 6. Even when the display switch 4 is in the "ON" state, the display mode is immediately switched to the power saving mode when the worker leaves the seat and the proximity sensors 13 and 22 become insensitive.

The power saving time limit means 31 timely monitors a continuous state such as no input from the input means 11 by a predetermined power saving time limit monitoring while the power is turned on, and the power saving time limit is determined. When reaching, the power distribution unit 7 is instructed to switch from the normal operation mode to the power saving mode via the control determination unit 6.

The display switch 4 is provided according to the present invention, and is provided, for example, as a part of the input means 11 of the input section 1 as shown in FIG. The display switch 4 is operated “ON” when the worker interrupts the input during the normal input work and performs a thinking work while referring to the display image on the display screen 23 (FIG. 2) of the display unit 2. .
This “ON” information serves as an instruction for setting a display mode to cut off power supply other than screen display on the display unit 2 to the power distribution unit 7 via the control determination unit 6.

When the power saving switch 5 is in the "ON" state by the "ON" operation of the display switch 4, the power saving switch 5 is switched to the "OFF" state. Further, when the display switch 4 is operated to be "ON", the power saving time monitoring is canceled and the initial state is returned. However, as described above, when the worker leaves the seat, the proximity sensor 13/22 is detected. The display mode is immediately switched to the power saving mode due to the insensitivity information.

On the other hand, when the display switch 4 is operated "OFF" in the display mode, the mode is switched to the power saving mode.

Like the display switch 4, the power saving switch 5 is provided according to the present invention, and is provided, for example, as a part of the input means 11 of the input section 1 as shown in FIG. To do. The power-saving switch 5 is operated “ON” when the worker does not leave his seat during the normal input work, interrupts the data input by the input means 11 and temporarily stops using the data processing device. Based on the “ON” information, the power supply distribution unit 7 is instructed to supply power to the power distribution unit 7 via the control determination unit 6 in the minimum range of the control unit 3 and the like, and to cut off power supply in a wide range including the display screen 23. .

If the display switch 4 is in the "ON" state when the power saving switch 5 is operated "ON", the display switch 4 is switched to the "OFF" state.

The control determination section 6 includes a contact sensor 12, proximity sensors 13 and 22, a power saving time limit means 31, a display switch 4,
Also, it receives a signal from the power saving switch 5 and instructs the power distribution unit 7 to supply power to the input unit 1, the display unit 2, the control unit 3, etc. of the device according to the operating status of the device. In FIG. 2, the control determination unit 6 is installed in the control unit 3, for example.

First, when the power is turned on, the normal operation mode is set, and at least one of the proximity sensors 13 and 22 and the touch sensor 12 or the input means 1 is detected.
With the data input of 1, the setting of the normal operation mode is continued. Further, the normal processing operation is performed by the data input of the input means 11.

On the other hand, when there is no data input from the input means 11 and no detection by the touch sensor 12, the operator is present, so that the display switch 4 can be detected even if the proximity sensors 13 and 22 detect it. If there is an "ON" operation, the display mode is set, and if there is an "ON" operation for the power saving switch 5, the power saving mode is set, and power saving is performed at each stage.

On the other hand, neither data input from the input means 11 nor sensing by the touch sensor 12 is performed, and the display switch 4 and the power saving switch 5 are both "OF".
In the F "state, the power saving time limit monitoring of the power saving time limit means 31 is started.

After the power saving time monitoring is started, if any one of the detection by the contact sensor 12 and the data input from the input means 11 occurs, the power saving time monitoring is canceled and the initial state is set. Then, the normal operation mode is set.

When the power saving time limit is reached, and when the power saving switch 5 is operated "ON", the power saving mode is set for both, and the power saving time limit is set by this power saving mode setting. Monitoring is canceled and returns to the initial state. On the other hand, when the display switch 4 is operated "ON", the display mode is set, and the power saving time period monitoring is also canceled by this display mode setting to return to the initial state.

When the power saving mode is set, the sensing by the proximity sensors 13 and 22 is ignored, the sensing by the contact sensor 12, the data input from the input means 11, and the power saving switch 5 "OFF". When any one of the operations occurs, the power saving mode is canceled and the normal operation mode is set. Further, when the display switch 4 is operated "ON", the power saving switch 5 is interlocked with "OFF".
And the display mode is set.

On the other hand, when the display mode is set,
When any one of the sensing by the touch sensor 12 and the data input from the input means 11 occurs, the display mode is canceled and the normal operation mode is set. On the other hand, when the operator leaves the seat and any one of the non-sensing of the proximity sensors 13 and 22, the “OFF” operation of the display switch 4 and the “ON” operation of the power saving switch 5 occurs, the display is displayed. The mode is released, the power saving mode is set, and the display switch 4 is brought into the “OFF” state in conjunction with the “ON” operation of the power saving switch 5.

In the above description, the display showing the operation in each mode is not described, but for example, the lamp and a part of the display screen are displayed by at least one. Further, although the power saving mode and the display mode are not described in detail, the contents may be freely set. Further, regarding the operation of the touch sensor, it has been described that the touch sensing immediately switches to the normal operation mode setting, but it may be a process of switching from the power saving mode to the display mode. Further, although the operation associated with the change in the state of the sensor, the switch and the like has been described, the operation is free as long as the function for solving the above problems is satisfied, and the above description does not limit the present invention.
