PURPOSE:To reduce a manufacturing cost, and to execute freely a cutting work by providing a rotary supporting shaft on a control member and a base end part of a free bear, respectively, and also turning the free bear and the control member by a prescribed angle by using each supporting shaft a supporting point. CONSTITUTION:A vertical plate 11 is provided on a base 20, and also at its every prescribed sheet number internal, a rotary supporting shaft 35 is provided. The supporting shaft 35 is supported freely turnably through bearings 23, 24 between side walls of the base 20, and a free bear 30 is placed at a suitable interval on its upper face. On the side wall surfaces of the base 20, spline shafts 41, 42 are provided in the X and the Y axis directions, respectively, and a control member 40 is slid and also attached turnably in the peripheral direction. After an object to be worked has been positioned, the free bear 30 is turned by 180 deg. and placed on work receiving pins 10a, 10b, etc., and subsequently, the control member 40 is turned by 180 deg.. In this way, the manufacturing cost is reduced, also, a limit of cutting is dissolved, and the work is executed freely. |
