<p>PROBLEM TO BE SOLVED: To operate an arrow without an unnatural feeling compared with a POS operation by permitting a touch pad surface to be vertically movable, providing a switch under it and turning on the switch when more than fixed pressure force is added to the touch pad surface. SOLUTION: A spring 4 for pushing-up the touch pad 2 in order to permit the touch pad 2 surface to be vertically movable is provided in a lower part and also the switch 3 is fitted. The height of the touch pad 2 is aligned so as to be touched in standing work and formation is executed by inclining an angle. When more than fixed pressure force is added to the touch pad 2 surface by a finger, etc., it is lowered downwards, the switch 3 is depressed, the arrow on the screen of a liquid crystal pannel is operated and target data such as a job column, etc., is established. Thus, the arrow is operated without the unnatural feeling compared with the POS operation and also a pointing device is operated in a standing posture.</p> |
