Sheet processing apparatus

摘要

A sheet processing apparatus is provided with an operation member 70 and an motion member 61 that rotates with a force of the operation member 70 through the connection part 70c and applies force to an acting member 60. A fulcrum O of a rotating operation of the operation member 70 moves depending on an operation of the operation member 70. Thereby, a first length L1 between the fulcrum O and a part E1 at which the operation member 70 is applied with the force and a second length L2 between the fulcrum O and a part E2 at which the force is applied from the operation member 70 to the motion member 61 are changed.
