Abstract

PURPOSE:To avoid the recalculation mode during calculation and at the same time to ralize a quick recalculation, by providing a mobile object that slides in the lengthwise direction on the outer surface of an upper or lower frame which is opposite to the free end of an operation body. CONSTITUTION:A pair of rods 10 for recalculation are provided in parallel to each other on the back of a beam, and an operation body 11 is fixed at the position where the shaft attachment part of a link 8 overlaps. Then a mobile object 14 is provided on the outer face of the upper or lower frame which is opposite to the free end of the body 11 to slide in the lengthwise direction. Thus the recalculation mode is obtained by swinging the body11 by the sliding of the object 14. In such way, the recalculation mode by mistake during a calculation is avoided. And at the same time, the calculation mode is quickly obtained when necessary.
