Abstract

A sheet binding device and a sheet post-processing apparatus. A sheet binding device includes: a first tooth member having a plurality of teeth arranged; and a second tooth member having a plurality of teeth arranged, the The second tooth-shaped member is engaged with the first tooth-shaped member to clamp and bind the sheets in cooperation with the first tooth-shaped member, and is inclined relative to the first tooth-shaped member from the beginning of the engagement to the completion of the engagement. .

Description

technical field [0001] The present invention relates to a sheet binding device and a sheet post-processing apparatus. Background technique [0002] There is known a recording material binding apparatus in which a plurality of stacked recording materials are joined together by being nipped in waves by a pair of toothed members each having a ring gear, pressed and deformed (see Japanese Unexamined Patent Application Publication No.2011-201654). [0003] If the teeth in two paired toothed members are misaligned with each other, uneven contact occurs, that is, one tooth surface of one tooth is in strong contact with the tooth on the other side, and the other tooth surface is in strong contact with the tooth on the other side weak tooth contact. Sometimes the recording material is damaged on the strong contact side, while the bonding force is reduced on the weak contact side. Contents of the invention [0004] It is therefore an object of the present invention to suppress un...
