However, computers have come to be widely used as general-purpose tools in daily work, and information communication via the Internet has been actively carried out, and the time required for operating a mouse has been long. Nowadays, physical stress given to an operator with the operation of the conventional mouse 60 has become a problem. That is, the conventional mouse 60 had to be operated while pinching both sides thereof with the thumb and the ring finger (little finger). Stress is exerted on the upper arm, shoulder, and neck, resulting in a disorder called neck-shoulder-arm syndrome in which the long-time operation of the mouse 60 impairs the soft tissues near the neck, shoulder, and upper arm. There was something. In addition, the conventional mouse 60 had to be placed on the mouse 60 with the forefinger and the middle finger extended in order to perform a click operation, but if the fingers were extended, the muscles of the forearm would be stressed. It was not preferable from the viewpoint that it became easier to apply, and that the greater the number of fingers extended, the more easily the forearm muscles were more stressed.

Further, in the conventional mouse 60, since the trackball 63 of the X-axis and Y-axis detecting unit is provided substantially at the center of the bottom surface of the mouse 60, it is difficult to move the mouse 60 up, down, left and right delicately. Skills were required because the cursor had to be adjusted to the desired coordinate position on the display screen by relying on the palm of the forefinger or the middle finger located near the center of the hand placed on or on the palm sensation, especially for beginners. Operation was not easy.

Therefore, the present invention has been made to solve the above-mentioned problems in the conventional mouse.
