ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
This invention relates to peripheral equipment of computer, more particularly, to a multi-functional documentary clamping holder that is adjustable in various angles and disposable on a desk or beside a monitor at will.
2. Description of the Prior Art
As it is well known that a computer can be used for learning language, augmenting knowledge, linking a network for communication with different people all over the world or searching data, computer graphing, data storing, or composing, etc. When computer typewriting in early days, a typist was supposed busy in swaying her head back and forth between a monitor and a documentary sheet on a desk. For eliminating the inconvenience, a documentary clamping holder shown in
FIG. 1
has been developed later on and used to clamp at an edge of worktable. This prior documentary clamping holder comprises an extendable holding arm disposed on its top having a joint for adjusting angle and direction and a panel for loading documents coupled with its open end being adjustable in oblique angle. Nevertheless, such a prior documentary clamping holder is not deft enough in adjustment with its limited holding arm that can scarcely satisfy various requirements. Another kind of a prior clamping holder shown in
FIG. 2
is provided with a cantilever having a stationary base at one end fixed in a corner of computer monitor and a fixing clamp at the other that can only clamp a sheet of paper. Anyway, the function of the prior documentary clamping holder is imperfect in one way or another and is pending for improvement.
SUMMARY OF THE INVENTION
The primary object of this invention is to provide an improved multi-functional documentary clamping holder for computer typewriting with a deft structure, which doesn't occupy too much space when stored, can be assembled simply and adjusted easily. Particularly, as it can be adjusted in a three-dimensional space, it may be located on a desk or beside a monitor for a user to adjust for an optimum angle.
For achieving the abovesaid object, this invention is provided with a support framework composed of a coupling base and a panel-clamping frame, wherein one end of the support framework is inserted in a panel, the other is united with a disposal platform or an adhering board for placing this invention beside or on a computer monitor alternatively. In virtue of two snap buttons pivotally disposed between a movable arm and a coupling base, two clamping pieces pivotally disposed in the movable arm, an insertion-disposed piece in the panel, and an indented groove, the panel can be moved vertically, horizontally, or turned around in a predetermined three-dimensional space.
