ABSTRACT:
An apparatus for changeably setting a width of a sheet guide path for a sheet includes a pair of sheet guide members set at both sides, respectively, of the sheet guide path to face each other and to be movable in a transverse direction of the sheet guide path so as to define the width of the sheet guide path therebetween and a pair of positioning members which move one of the sheet guide members, respectively, in the transverse direction to position the corresponding sheet guide members. The positioning members are rotatable about a mutual axis extending in the transverse direction and each having a plurality of cam surfaces which are circumferentially offset from each other about the mutual axis and stepwisely offset from each other in the direction of the mutual axis, the sheet guide members being engaged with the cam surfaces of the corresponding positioning members.
