| 摘要 | PURPOSE: To perform enlarging, reducing, and scrolling operation for a display picture on a CRT in parallel to editing input operation without interrupting operation or consideration for editing input. CONSTITUTION: An operator when viewing the details of the CRT picture 4 in editing input operation for a CRT 1 by operating a mouse 2, a keyboard, etc., puts his eyes to the screen unintentionally as shown by an arrow 6. At this time, the upper half body of the operator moves and the center of gravity moves forward to operate a piezoelectric step 3a fitted to a chair 7, thereby enlarging the CRT picture 4. When the operator sees the whole picture, the eyes leaves the CRT screen 4 unintentionally, so the center of gravity of the operator moves to the rear part of the chair 7 and the piezoelectric switch 3c is operated to reduce the picture 4.
