Patent ID: 8382089

Claim:
A sheet cutting apparatus, comprising: a conveying member configured to convey a half-folded sheet bunch into which sheets are half-folded, the conveying member being provided in a conveyance path through which the half-folded sheet bunch is conveyed; a registration member which comes into contact with a leading edge portion of the conveyed half-folded sheet bunch to correct a skew feed of the half-folded sheet bunch; a cutting member configured to cut a trailing edge portion of the half-folded sheet bunch in a sheet-bunch conveying direction of the half-folded sheet bunch; and a controller configured to control the conveying member, the registration member, and the cutting member in such a manner that after the skew feed is corrected by the registration member, the registration member is retracted from the conveyance path, and thereafter the leading edge portion of the half-folded sheet bunch is conveyed downstream of a position in which the registration member comes into contact with the leading edge portion in the sheet-bunch conveying direction by the conveying member, to convey the trailing edge portion of the half-folded sheet bunch to a cutting position of the cutting member so that the trailing edge portion is cut with the cutting member.
