Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a computer mouse for controlling a cursor on a monitor, which has a case guided by hand on the bottom surface and a command key which is gathered in the case and operated by a finger.

[0002]

[Prior art]

 In order to control the movement of the cursor on the computer monitor, so-called computer mice of various structures are known. Most computer mice have a generally basal bottom surface with a curved or at least upper case portion that bends in the direction of the overlying finger. In this upper case part, the keys necessary for inputting commands are usually arranged closely together. It is usual to operate these keys with the index finger and middle finger of the operator, and hold and move the mouse itself with the thumb and the remaining fingers. The key operation direction is slightly deviated from the vertical plane. However, it was found that operating the key with a relatively extended finger was very tiring. In order to operate the keys arranged more closely with the index and middle fingers of the hand, a high degree of concentration is required.

From the German patent application DE 37 05 492 A1 a case-shaped XY input device is known, which is provided with key elements on the upper and vertical side surfaces. Since this is a multi-function device, the key layout is not advantageous from an ergonomic point of view. This is because providing a key element to be operated by the thumb on a flat vertical wall that also serves to hold and guide the mouse by the ball of the thumb makes handling difficult.

[0004]

[Problems to be solved by the device]

 The problem underlying the present invention is to provide a computer mouse that can be guided on the bottom surface without fatigue and enables easy key operation.

[0005]

In order to solve this problem, according to the present invention, the operator's thumb and forefinger are operated in different directions, and the ergonomic spacing condition and position condition of the thumb and forefinger are met. The command key corresponds to the command key, and it has a case or a bulge that supports the ball of the foot, and this bulge forms a grasping surface and a placement surface for the ball of the ball, and a command key corresponding to the thumb It is provided in the front end area of the grip surface.

[0006]

[Effect of device]

 The configuration of the computer mouse case according to the present invention and the arrangement of the operating element according to the present invention allow the operator's hand to grasp the case without applying any load. The fingers (thumb and index finger) for operating the command keys are always kept in a natural bent posture. In this range, a particularly ergonomically adapted case configuration of the thumb makes it possible to transfer an important input function, the so-called mouse click, to the thumb. This significantly improves the monitoring of finger movements.

[0007]

Embodiment

 Advantageous configurations are shown in claims 2 and 3. The configuration according to claim 2 helps ensure that the finger for operating the command key is placed. According to the third aspect, the case is provided with another recess for fixedly placing a finger.

[0008]

【Example】

 An embodiment of the invention is shown in FIGS. The figure shows Case 3 of the computer mouse according to the present invention, which is adapted to the ergonomic conditions of the human hand. The basic shape corresponds to the space surrounded by the human hand with a slightly bent finger (natural finger posture). In particular, in order to reliably and comfortably guide the computer mouse on the bottom surface, the bulging portion supporting the ball of the thumb is useful, and the bulging portion forms the grasping surface 4 and the mounting surface 5. By providing the command key 1 in the range where the grasping surface 4 ends in front, the command key that is most frequently operated, that is, the unique mouse click can be configured to be comfortable and less fatigued. By providing the command key 2 in the front region extending diagonally downward of the case 3, when the command keys 1 and 2 are operated by the operator's thumb and forefinger, particularly good matching of the motion process is possible. . To ensure that the fingers are placed on keys 1 and 2, these keys are recessed according to the shape of the rounded tip of the fingers. A properly formed recess 6 is provided to improve the movement and grasp of the computer mouse.
