PROBLEM TO BE SOLVED: To provide a novel apparatus for straightening a bent supply of a paper sheet for case manufacturing to correct an attitude at a stop reception of a front end of the supplied sheet. SOLUTION: In the apparatus for straightening a bent supply of a paper sheet for case manufacturing, a section for advancing a paper sheet by releasing a holding pressure is provided at an intermediate part of a supply conveyor for holding and supplying a cut sheet to a conveyor for sizing and assembling a paper case, and a stopper projecting from and retracting in the section is provided. Thus, two points of both sides of a front end of the sheet advanced by releasing the holding pressure by projecting or retracting the stopper in the section to match the timing of the stopper are brought into contact with the stopper to straighten the attitude of the sheet including the bent and to send and supply the sheet.
