PROBLEM TO BE SOLVED: To obtain an equipment capable of preventing the dirt of a moving amount detection part for a mouse to be an information input device without using a mouse pad which is a nuisance, to maintain stable and accurate input and to obtain a comfortable operation environment. SOLUTION: A sheet has an extra fine fiber layer 1 of woven fabric having no self-fluff generating property or nonwoven fabric mainly consisting of an extra fine fiber string of 0.0001 to 1 denier as a wiping surface and has a viscous adhesive layer 2 on a rear face. The thickness of the sheet is set to a value not more than the dimension of a ball projection of which moving amount can be detected from the bottom main part of the mouse. The sheet is stuck and fixed to the bottom of the mouse by the viscous adhesive layer 2 so as to surround the projected part of the ball and the wiping face consisting of the extra fine fiber string is used as a plane included in flatness consisting of the bottom part contact face of the mouse and the contact operation face of the ball of which moving amount can be detected. Input operation is utilized for wiping operation, so that the ball can be always rotated on a face free from an oil film or foreign matters by a wiping effect. The abrasion of the operation face can be prevented by sliding on a soft fiber face. In addition, the sheet has versatility and can be inexpensively provided. |
