PURPOSE:To enable a device to be easily adjusted so as to hold an object in a sheet form to meet change in dimension of the object by arranging both stationary pins and numbers of guide holes which extend radially, for movable pins on a stage so as to enable the movable pins to move along the above said guide holes. CONSTITUTION:This is a device to hold an object in a sheet form by enclosing the object with both stationary and movable pins. A stage 1 in the device includes stationary pins 2 and numbers of guide holes 3, for the movement of the movable pins where the guide holes extend to the radial direction. In addition, a movable table 5 which has the same numbers of guide holes 4 that correspond to those on the stage, is arranged in such a manner that the guide holes on the movable table intersect the guide holes on the above said stage. And the movable pins 6 are placed at the position where the upper side hole intersects the lower side hole. The movable table 5 is allowed to move by means of a handle 10 permitting the movable pin 6 to move within the guide hole 3 on the stage. Accordingly, this configuration enables the device to be easily adjusted so as to hold the object in a sheet form to meet change in dimension of the object. |
