Abstract
A sheet binding device binds a sheet bundle by causing a movable-crimping-member moving unit to move a movable crimping member thereby holding a sheet bundle between crimping members. The movable-crimping-member moving unit includes: a link mechanism that includes a first link member rotatably connected to the movable crimping member, a second link member rotatably connected to a fixed member fixed to a device body and connected to the first link member through a connecting part; a connecting member rotatably connected to the connecting part, and capable of moving between a first position causing the link mechanism to be extended and a second position causing the link mechanism to be more flexed than in the first position; and a connecting-member moving unit that includes a rotary member capable of rotating on a displaceable rotating shaft, and reciprocates the connecting member by rotation of the rotary member in one direction.
