<p>PURPOSE:To improve operability, by forming a key for a cursor moving key switch in the hemispherical shape, and fitting a function key relating to the movement of the cursor to the side of said key. CONSTITUTION:When a cursor 9a is to be moved to a cursor position 9b, the hemispherical cursor moving key 4 is slided in the direction of a cursor switch 6X+. At this time, a spherical operation transmitting ball 5 is pushed and contacted with a plate spring part of a cursor switch 6 and a signal from the cursor switch 6 is controlled by a CPU in a device body 1. The balls 5 and the switches 6 to sense the balls 5 are fitted to the cursor moving key 4 at four positions, upper, lower, right, and left. When a cursor locking key 7 fitted to the side of the moving key 4 is pushed by a finger point, a plate spring part of a cursor lock switch is sensed and the cursor lock is stored in the CPU.</p> |
