<p>PROBLEM TO BE SOLVED: To select a grip having a good operability in accordance with operator's more skilful hand and the size of a hand and also to reduce the cost of product inventory by providing a main body part and a grip part which is attachable and detachable to/from the main body part and is gripped by an operator. SOLUTION: The projecting part 12 of a mouse body 10 is inserted fittingly into an operation part 23 of a grip 20. The side on this side of the grip 20 and the side on this side of the part 12 are screwed after the insertion. A cord 110 is connected to a personal computer, etc., in this state and a mouse M1 is used with the grip 20 grabbed by a right hand. In such a case, its operability is satisfactory because the projecting and recessing shapes of the palm of the hand at the time of grabbing the right-hand grip 20 fit the shape of the grip 20. A left-hand grip is provided with a linear part and a curved part which are adapted to the projecting and recessing shapes of the palm of a left hand in the same way as the grip 20. When a left-handed user uses the mouse M1 , its operability is further improved by setting the functions of main and sub switches to reversed states with an on/off switch 17.</p> |
