A sheet conveyance device includes a conveyance roller pair to convey a sheet, a skew correction roller pair to correct a skew of the sheet in a state in which the skew correction roller pair is being stopped, first and second conveyance guides, and a protrusion. The first conveyance guide includes a bend contact portion to come into contact with a portion forming a bend on the first surface of the sheet. The second conveyance guides the sheet. The protrusion is disposed between the skew correction roller pair and the bend contact portion to come into contact with the first surface of the sheet. The protrusion protrudes toward the second conveyance guide from the first conveyance guide in a manner as to intersect with a straight line connecting two nip portions and the bend contact portion in a cross section perpendicular to a width direction.

A sheet conveyance apparatus that conveys a sheet along a curved path shorter than the sheet and corrects skew of the sheet, includes: a conveyance roller that sends the sheet into the curved path; a guide that guides the sheet along the curved path; and a gate that is hinders advance of the leading end, generates a moment about a normal of the sheet passing through the leading end, and allows advance of the leading end by being pushed away by the leading end, wherein the guide includes a projection projecting toward a movement space for the sheet on a surface facing the movement space, and the projection abuts a center portion of the sheet in a longitudinal direction and generates a moment about an axis parallel to an advance direction of a portion that has come into contact with the projection.

In one example, a sheet media alignment system includes: a guide (12) defining a curved media path (14) that extends from an upstream part of the guide to a downstream part of the guide; a movable blocker (16, 56) to block the curved media path (14) at the downstream part of the guide, the blocker movable into and out of a blocking position in which the blocker is spaced from the downstream part of the guide a first distance; and a driver (24, 58) upstream from the curved media path to drive a media sheet into the guide along the curved media path and into the blocker. The driver is spaced from the upstream part of the guide a second distance greater than the first distance such that a media sheet driven into the blocker will buckle between the driver and the guide before it will buckle between the guide and the blocker.

A medium conveyance route switching device includes: a support unit located at a branching point where conveyance directions of a medium converge in three directions; a gate assembly including a plurality of gates to guide at the branching point the medium to different conveyance paths; and a rotation mechanism configured to selectively rotate the plurality of gates. The support unit includes: a first support piece having a first through-hole portion; a second support piece having a second through-hole portion; a third support piece having a third through-hole portion; a first bending connection portion rotatably connecting one end of the first support piece and the second support piece; a second bending connection portion rotatably connecting the other end of the first support piece and the third support piece; and a fixing shaft inserted into the first through-hole portion, the second through-hole portion, and the third through-hole portion.

A sheet-conveying device contains a first linear sheet-conveying path on which the sheet is conveyed, a curved sheet-conveying path connecting the first linear sheet-conveying path and a second linear sheet-conveying path connecting the curved sheet-conveying path. A curved conveying guide is provided at only an outside of a curved sheet-conveying route. Conveying guide rollers are provided at an upstream side of the curved conveying guide. The conveying guide rollers contain a driving roller which is arranged at outside of the curved sheet-conveying path and a driven roller which is arranged at inside of the curved sheet-conveying path. The driven roller has a diameter more than that of the driving roller. The driven roller also has hardness less than that of the driving roller.

A sheet conveyance apparatus that conveys a sheet along a curved path shorter than the sheet and corrects skew of the sheet, includes: a conveyance roller that sends the sheet into the curved path; a guide that guides the sheet along the curved path; and a gate that is hinders advance of the leading end, generates a moment about a normal of the sheet passing through the leading end, and allows advance of the leading end by being pushed away by the leading end, wherein the guide includes a projection projecting toward a movement space for the sheet on a surface facing the movement space, and the projection abuts a center portion of the sheet in a longitudinal direction and generates a moment about an axis parallel to an advance direction of a portion that has come into contact with the projection.

A device for winding an electrode plate includes a feed roller configured to guide a first electrode plate or a second electrode plate, each of the first electrode plate and the second electrode plate including a plurality of electrode tabs protruding from one side, a deformation reducing member spaced apart from an outer circumferential surface of one end of the feed roller and configured to guide the electrode tabs fed to the feed roller to be brought into close contact with the outer circumferential surface of the one end of the feed roller to reduce deformation of the electrode tabs, and a winding unit configured to wind together the first electrode plate or the second electrode plate transferred by the feed roller and a separator interposed between the first electrode plate and the second electrode plate.

An image forming apparatus includes a conveying guide and a sheet member. The conveying guide is provided in a joining section and guides a sheet to a conveying roller pair along a main conveying path. The sheet member is provided in the joining section and configured to form a lower conveying path with the conveying guide and to guide the sheet from an upper conveying path toward the main conveying path. The conveying guide has a convex guide part and planer guide parts. The convex guide is provided at a center portion and projects toward the sheet member. The planer guide parts are provided on both sides of the convex guide part. A first gap formed between the convex guide part and the sheet member is narrower than a second gap formed between the planer guide part and the sheet member.

A separation device (1) intended to separate a profiled element (2) from a conveying surface (3) which conveys the profiled element (2) in a longitudinal direction (L0) comprises a detachment roller (10) which is mounted so as to be able to rotate on a support (11) about a detachment axis (X10), and which is intended to be interposed, in an engagement configuration (C1), between the profiled element (2) and the conveying surface (3) to cause the profiled element (2) to become detached from the conveying surface (3).

A temporary holding section winds banknotes onto an outer peripheral face of a circular, cylinder-shaped and rotatably supported drum to retain the banknotes between a facing portion and the outer peripheral face. More specifically, the temporary holding section uses an upper side tape and a lower side tape, that respectively have one end wound onto the drum, such that accompanying rotation of the drum, the supplied banknotes are sandwiched between the tapes and the outer peripheral face. Moreover, in the temporary holding section, a movable section that presses the banknote against the drum outer peripheral face while being movable with respect to the drum is positioned with the other end further away from the drum than the facing portion.
