<p>PURPOSE:To enable the pointing in a picture element unit, while coming into contact directly with the display surface by providing a ball, a rotating state output means for the ball, and a movable contact connected to the contact face of the inside of a case. CONSTITUTION:On the peripheral wall of the inside of a pen mouse 1, the contact face 3 consisting of many contacts is arranged, a movable contact 4 for coming into contact with this contact face 3 is provided, and the movable contact 4 is constituted so as to move to the lowest part by gravity and comes into contact with the contact of the contact face 3, even if the pen mouse 1 is rotted. Accordingly, by the information of a fact that the tip part 4-1 of the movable contact 4 comes into contact with the contact face 3, the vertical downward state of the pen mouse 1 is recognized. Therefore, since the information of the pen mouse 1 is transferred to a data controller main body 7 through a lead wire 7, in which direction and by how many dots the pen point of the pen mouse 1 is moved based on the vertical downward state as a reference can be informed to the data controller main body 7 by calculating the displacement caused by this vertical downward information and a ball 2.</p> |
