Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a desk for office automation equipment, more specifically, a personal computer (hereinafter, simply referred to as "personal computer") and a word processor (hereinafter, "computer").
The present invention relates to a desk for OA equipment suitable for mounting and operating OA equipment such as "word processor").

[0002]

2. Description of the Related Art Conventionally, as desks for mounting and operating OA equipment, various desks having a devised top plate have been provided. For example, a desk having a structure in which a keyboard mounting plate or a mouse operation plate can be pulled out from below the top plate, or a shape in which the keyboard mounting part protrudes from the top plate toward the front in order to secure a mounting space for OA equipment. Desks and the like using the odd-shaped top plate are provided.

There is also provided combined furniture in which a desk and a side desk are combined and installed in an L shape in a plan view, and a corner portion having a large depth width is used as an installation space for OA equipment, but the cost is high. In addition, it is inevitable that the user sits at an angle to the desk and the sitting posture becomes unnatural.

Further, the top plate is divided into a rear part and a front part, and the heights thereof are adjustable, respectively. The OA device main body or the display is placed on the rear top plate, and the keyboard is placed on the front top plate. A structured OA desk is also provided. In this case, since the display and the keyboard can be set to the optimum height for use, the convenience of use is good, but the drive mechanism is complicated and generally expensive.

In the OA equipment, the mouse is frequently operated on the top plate, but in that case, it is tiring to keep the arm floating, so the mouse should be placed deeper than the keyboard operation position.
The arm is put on the top board and it is operating. Therefore, when moving from mouse operation to keyboard operation and vice versa, the distance to move the arm becomes large, and it is hard to say that it is ergonomically ideal. In the case of the type in which the mouse operation plate is pulled forward from the top plate, it is practically impossible to place the arm on the mouse operation plate due to the problem of support strength of the mouse operation plate.

[0006]

SUMMARY OF THE INVENTION In view of the above situation, the present invention is suitable for mounting and operating an OA device such as a personal computer or a word processor. The point is to provide an OA device desk that can be placed on the desk and that is ideal for ergonomics by minimizing the movement of the arm when the keyboard and mouse are used alternately.

[0007]

In order to solve the above-mentioned problems, the present invention forms an arm rest part projecting forward on at least one of the left and right sides of the front part of a top plate supported by legs, and A desk for OA equipment was constructed in which a front edge portion other than the arm rest portion was a palm rest portion.

Further, the top plate is separated into a rear top plate on which the main body of the OA device or a display and a keyboard of the OA device are placed, and a front top plate having the palm rest portion and the arm rest portion, and the leg portion. When the rear end of the front top plate is detachably connected to the front end of the rear top plate supported by
The front top plate can be used for both right-handed and left-handed users, and the mode can be easily changed.

[0009] Further, by forming an inclined surface which descends frontward on the upper surfaces of the front edge portions of the palm rest portion and the arm rest portion, and by forming an inclined surface symmetrical with the inclined surface on the lower surface, keyboard operation is possible. The pressure on the palm when moving and the pressure on the arm when operating the mouse can be relieved, improving operability and
Can withstand long-term use.

Further, when the inclined surface is made of a soft material, the effect of relieving the pressure on the palm and the pressure on the arm is further enhanced.

Embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. FIG. 1 shows the OA of the present invention.
FIG. 2 is a perspective view showing a typical embodiment of an equipment desk, and FIG. 2 is a plan view for explaining its use state. In the figure, reference numeral 1 is a leg portion, 2 is a top plate, 3 is an arm rest portion, and 4 is a palm rest. Parts are shown respectively. Further, reference numeral D in FIG. 2 is a display of an OA device, K
Indicates a keyboard, and M indicates a mouse.

In the desk for office automation equipment according to the present invention, an arm rest 3 protruding forward is formed on at least one of left and right sides of a front portion of a top plate 2 supported by a leg 1, and the arm rest 3 is formed.
The front edge portion other than the above is the palm rest portion 4.

More specifically, the top plate 2 of the present embodiment.
Has a rear edge that bulges in an arc shape, and both side edges slightly expand toward the front, and forms an arm holder 3 that extends forward from a right edge, and the front edge portion other than the arm holder 3 is formed. The palm rest portion 4 is formed by recessing in an arc shape, and the outer circumference is a curved and smoothly continuous shape. Then, the display D is placed on the rear part of the top plate 2, the keyboard K is placed in front of it, and the mouse M is placed on the extension line of the arm rest 3 on the side of the keyboard K. To use.

First, when the keyboard K is operated, the palm is placed on the palm rest 4 for positioning, and the key is pressed with the fingertip. Next, when operating the mouse M, the hand is released from the keyboard K, the arm is placed on the arm rest portion 3, and the mouse M is slid on the top plate in a conventional manner for use. In the case of the present invention, since the arm rest 3 is located in front of the palm rest 4, when the arm is placed on the arm rest 3 in a stable state, the position of the hand including the palm and the fingertip is changed. It is just to the side of the keyboard K, and at this position the mouse M
Can be operated. Therefore, when the keyboard operation is changed to the mouse operation, or when the mouse operation is changed to the keyboard operation, it is sufficient to move the arm only in the lateral direction without the forward and backward movements. Therefore, the keyboard K and the mouse M are used alternately. In this case, the movement of the arm can be minimized, and ergonomically ideal operability can be realized.

Further, by forming the inclined front surfaces 5 and 6 on the upper surfaces of the front edges of the palm rest portion 4 and the arm rest portion 3, the palm is pressed when the keyboard is operated and the arm is pressed when the mouse is operated. Can be relieved.
