  • Patent number: 11535480
    Abstract: To enable highly accurate fold processing by properly moving a sheet that has been subjected to fold processing. In a sheet processing apparatus that that performs fold processing in such a manner as to apply first fold processing to a sheet and then apply second fold processing at a position different from a fold line formed in the first fold processing so as to make one end of the sheet folded in the first fold processing lie inside the folded sheet, the first fold processing is applied to a sheet conveyed to an intermediate tray by a fold roller pair and, when a regulating stopper is moved to move the folded sheet that has been subjected to the first fold processing to a predetermined position of the intermediate tray, the folded sheet is gripped by a grip unit.

  • Patent number: 11377078
    Abstract: Provided is a vehicular operation pedal device having a fail-safe function to prevent backward movement of a step portion of an operation pedal mechanism at the time of a vehicle collision. A brake pedal device (1) includes a protrusion (90) which performs rotation restriction for preventing a rotating member (50) from rotating about a rotating shaft portion (14), and on which a restricting load (F2) acts by the rotation restriction. During the rotation restriction by the protrusion (90), a second load acts as the restricting load (F2) when a step portion (24) of an operation pedal mechanism (20) is fully stepped forward of a vehicle, and when the restricting load (F2) is greater than the second load, the rotation restriction is released due to deformation of the protrusion (90) by shearing or bending.

  • Patent number: 11294318
    Abstract: A sheet processing apparatus performs folding processing so that one end of a sheet exists inside the folded sheet. The sheet processing apparatus includes a transport path to guide a transported sheet, a rotating body pair capable of transporting the sheet in a first direction to perform folding processing, and in a second direction for switching back the sheet subjected to the folding processing, a folding blade that pushes the sheet to a nip portion of the rotating body pair, a press member that presses the sheet folded by the rotating body pair in the second direction, and a shift section that shifts the press member for pressing the sheet. In switching back the sheet, a control section controls transport of the sheet so that the one end of the sheet is halted within a region between the press member and a guide face of the transport path.
