Abstract

PURPOSE:To adjust easily a twist degree, by providing an open/close matter in a free open/close way having a range in which the reverse turning torque caused by a twist spring is set at zero, and attaching a twist degree adjusting means at least to an end of a twist spring. CONSTITUTION:An end of a twist spring 19 is put into a support hole 20 of a support foot 16, and a sleeve 21 at the other end is inserted into a holder 23. Then the holder 23 is fixed on the bottom surface of an automatic original feeder 14. The feeder is fully opened, and the correspondence between a screw hole 24A and a screw hole 25A is set identical with the standard twist degree. The positioning is carried out between these holes 24A and 25A. A screw 26 is inserted to these holes, and the sleeve 21 is fixed to the holder 23. In this cas, the open angle is set in a range of theta2-90 deg. for the attachment of the screw 26 to the holes 24A and 25A. When the feeder 14 is turned within an angle of <=theta2, the twisting force is applied to a twist spring 19. Then the feeder is finally turned onto a copier 15, and accordingly the reverse torque nealy equal to the turning torque caused by the empty weight of the feeder 14 which is produced pivoting on a fulcrum 18 is obtained by the spring 19.
