[0002]

2. Description of the Related Art Generally, a data processing such as a relatively small computer called a workstation, a personal computer or the like, or a word processor or the like which is a relatively small computer specialized for enhancing a document creating function. In a device, usually, a plurality of key switches are provided as main constituent elements, and a keyboard forming a data input operation unit, which is supposed to input data by operating them, is inputted from a keyboard. Data that is supplied, performs arithmetic processing according to the supplied data to obtain processed data, and outputs a video signal based on the obtained processed data, and an image sent from the arithmetic processing section. A signal display unit is provided, and a data display unit for displaying an image based on the supplied video signal is provided. . In addition, in place of the keyboard or in addition to the keyboard, a mobile data input operation unit usually called "mouse" is often provided.

The arithmetic processing section is, so to speak, a main body section in a work station, a personal computer, a word processor, etc., and incorporates an input / output port section, a central processing unit, a data memory section, a data display processing section and the like. To be taken. Further, the data display unit is, for example, provided with a cathode ray tube having an image display screen unit, and performs image display based on a video signal sent from the arithmetic processing unit on the image display screen unit of the cathode ray tube. Thus, data display relating to the data input by the keyboard or the mouse is performed.

In a data processing device such as a work station, a personal computer, a word processor, etc., when it is used for business, for example, the power supply is turned on at the start of the work of the day and the operating state is changed. After being started, with or without a user, the machine remains in the operating state without being turned off until the end of the work of the day, so that the operating state can be maintained for a relatively long period of time. There are many ways in which it can be used. Under such a relatively long period of operation, the accumulated power consumption of the data processing device reaches a considerable amount, but in reality, the user is absent. Even if there is, the power consumption under the operating state is not useful.

Therefore, for example, in order to reduce the integrated power consumption amount in the data processing device without substantially affecting the smooth performance of the business, in particular, a large proportion is consumed in terms of power consumption. Pay attention to the data display part
If no data is input from the keyboard or mouse by the user's operation for a predetermined period set in advance, it is determined that the user is absent.
It has been proposed to automatically stop or reduce the power supply voltage supply to the data display section so that the data display section does not display a normal image.

[0006]

As described above, when the data input from the keyboard or the mouse by the user's operation is not performed for a predetermined period set in advance, the data display section is automatically operated. In a data processing device which is designed to stop or reduce the supply of power supply voltage so that a normal image display by the data display unit is not performed, data input from a keyboard or a mouse is performed within a predetermined period set in advance. In the case where the non-executed state is taken by the fact that the user is absent, the reduction of the integrated power consumption amount can be achieved without any other problem. However, when the data input from the keyboard or mouse is not performed for a predetermined period set in advance, the user examines the content of the processed data obtained by the arithmetic processing unit by displaying an image on the data display unit. As is the case when the data input is performed by monitoring the image display by the data display unit without performing the operation for data input by the keyboard or mouse as in the case of If the power supply voltage supply to the data display unit is automatically stopped or reduced by not performing it for a predetermined period set in advance, and the normal image display by the data display unit is not performed, the user can It will cause some inconvenience.

In view of the above point, the present invention provides a data input operation unit, which is operated by a user to input data.
An arithmetic processing unit that performs arithmetic processing according to data input from the data input operation unit to obtain processed data, and transmits a video signal based on the obtained processing data, and a video signal transmitted from the arithmetic processing unit When the operating state is maintained for a relatively long period under the provision of the data display unit for displaying an image based on, for example, without the user performing an operation for data input by the data input operation unit. Even when the image display by the data display unit is monitored, the accumulated power consumption can be calculated without causing any inconvenience to the user and without hindering the smooth use condition by the user. It is an object of the present invention to provide a data processing device that can be effectively reduced.

[0008]

In order to achieve the above-mentioned object, a data processing apparatus according to the present invention performs processing by performing a data input operation section and arithmetic processing according to data input by the data input operation section. An arithmetic processing unit that obtains data and sends a video signal based on the obtained processed data,
A video signal sent from the arithmetic processing unit is supplied, and a data display unit that displays an image according to the video signal is included,
The data display portion of which is provided at a position to be the display front surface, and the detection means for detecting a user facing the display front surface within a range in which the distance from the data display portion is less than or equal to a predetermined value, and When the user's detection is not done for a predetermined period, in order to reduce the power consumption,
It is configured to include a power supply control means for stopping the supply of the power supply voltage to the main circuit system for displaying an image in whole or in part.

[0009]

In the data processing apparatus according to the present invention having the above-described structure, when the user is in a state of use, the user can display the data except when very special use is made. The position will be close to the front of the display in the section. Then, the detection of the use state by the user is not performed in response to the operation of the data input operation unit, but the distance from the data display unit is detected by the detection means provided on the display front of the data display unit. This is done by detecting a user facing the display front within a predetermined range, for example, 0.8 m or less, and when the detecting means detects the user, the data display section displays an image. The power supply voltage is supplied to each part including the main circuit system for performing the operation, and the image is appropriately displayed, while the detection unit detects the user for a predetermined period, for example, several minutes. If not done, the data display unit is in a state where the supply of the power supply voltage to the main circuit system for displaying an image is entirely or partially stopped by the power supply control means. Be scented.

As a result, when the user does not take a position in close proximity to the display front of the data display unit for a predetermined period, it is determined that the user is not using the image, and the image on the data display unit is not used. The supply of the power supply voltage to the main circuit system for displaying is entirely or partially stopped to reduce power consumption.

Therefore, the data processing device according to the present invention is
When the operating state is maintained for a relatively long period and the user is in the operating state, the data display is performed regardless of whether the user is operating the data input operation unit. The section can quickly display and maintain the appropriate image display, which does not hinder the smooth use by the user, and for example, the user can input data using the data input operation unit. Even when the image display by the data display unit is monitored without performing the operation for, it is assumed that the user is not inconvenienced. If it is,
By stopping the supply of the power supply voltage to the main circuit system for displaying an image in the data display unit wholly or partly, it is possible to effectively reduce the integrated power consumption.
