<p>PURPOSE:To hold the data input device in one hand and to easily input much data by the motion of a finger tip of one hand by mounting a movable instruction part in which a magnet is assembled on a main body fixed plate, moving the movable instruction part from the center position to an index direction in the peripheral area, placing a movable instruction detection switch in operation with a magnetic force and sending an electric signal out. CONSTITUTION:A printed board 2 is fixed to the bottom part of the opening part in the top surface of the main body of the data input device, a fixed part magnet 4 is fixed at the center position of the printed board 2, and plural movable instruction detection switches 3 which send an input signal are arranged in the peripheral area of the fixed part magnet 4. Then the movable instruction part A in which the fixed part magnet 4 and the magnet B to be magnetized are assembled is mounted on the top surface of the main body fixed plate 1 which covers the opening part. When the movable instruction part A is pressed and moved toward the index, the movable instruction detection switches 3 operate detecting the magnetic force of the magnet B and output the input signal to a computer. When the depressig force to the movable instruction part 3 is reduced, the movable instruction part A moves to the center position of the main body fixed plate 1.</p> |
