Description

  The present invention relates to a kind of electronic equipment browsing work auxiliary equipment. In particular, the present invention relates to a notebook PC workbench that can adjust the viewing surface height.

Portable electronic equipment such as notebook PCs are widespread today, and a large amount of document data is created as electronic files and viewed on a computer.
On the other hand, although the desktop computer is the most widely used computer, the desktop computer is heavy, bulky, complicated and difficult to move, so the use place is limited compared to the notebook PC. On the other hand, notebook PCs are convenient to replace desktop computers because they can be carried around and used in any place, and can be used on office desks. However, the current desk height of the office desk is designed to match the height of the desktop computer, and the monitor screen of the desktop computer has a fixed base so that the user can move forward. The monitor screen of the desktop computer is set in the area where direct viewing is possible. For this reason, the document on the monitor screen can be browsed directly without bowing. However, notebook PCs are lightweight, thin, and compact, so they do not have a base suitable for the height of an office desk. Therefore, the monitor screen of the notebook PC is in the same state as if it was placed directly on the office desk, and even if it is tilted to the maximum angle, the user cannot look directly at the monitor screen unless the head is lowered. If the document on the monitor screen is viewed in an unnatural posture for a long time, it may have a serious effect on the mental health of the user such as myopia, strabismus, cervical spine damage, and back pain.
At the same time, when the laptop is placed on the desk, the keyboard will be horizontal if placed flat. However, the most suitable form for using the keyboard at this height is to have a suitable tilt angle. That is, there are certain difficulties in using the keyboard at the desk height, and it is not suitable for human engineering.
Although the present applicant has already devised a variety of document browsing devices that can be browsed with a natural posture, no similar products have been developed in the browsing area of electronic equipment such as notebook PCs. Therefore, continuing the paperwork in an environment in which a notebook PC user crawls at the time of browsing and inputs a keyboard in a horizontal state has a serious impact on health and is a point of concern for the applicant.
Japanese Patent No. 3678176

The known structure has the following drawbacks.
In other words, with a current office desk designed to fit the height of a desktop computer and using a notebook PC that does not have a base that is suitable for the height of the office desk, the user can keep his head up even when tilted to the maximum angle. Since the monitor screen cannot be viewed directly without lowering, if this condition lasts for a long time, there is a possibility of serious effects on mental health such as myopia, strabismus, cervical spine damage, and back pain. Furthermore, if the notebook PC is placed on the current office desk, the keyboard will also be horizontal, so the keyboard will not have an inclination angle that is desirable in terms of ergonomics.
