A turn guide is disposed between a first transport surface and a second transport surface on which a sheet is transported while being sucked. The turn guide has a plurality of guide ribs. The plurality of guide ribs have curved inverting transfer surfaces from an inversion start point corresponding to a first transport surface to an inversion end point corresponding to a second transport surface.

Provided is a sheet inverting apparatus wherein members, such as a roller, are not brought into contact with the printed surface of a sheet at all, and the occurrence of dirt can be prevented by eliminating friction of ink on the surface of the sheet. A first transport apparatus and a second transport apparatus each have a plurality of transport belts which move on transport tracks along sheet transport directions and a suction box which sucks the sheet on the transport belts through suction holes formed on the transport belts. A turn guide arranged between the first transport apparatus and the second transport apparatus has a plurality of guide ribs disposed between the transport belts. Each of the guide ribs coming into slidable contact with the sheet forms a curved inverting transfer surface from an inversion starting point side to an inversion end point side.

There is provided a sheet inverting and conveying mechanism for conveying a sheet in a first direction, inverting obverse and reverse sides of the sheet, and then conveying the inverted sheet in a second direction. The mechanism includes: a first conveyance section for receiving, at its conveyance face, one side of the sheet, and for conveying the sheet in the first direction; a sheet inverting section for receiving, at its bent inner peripheral face, one side of the sheet, and for inverting the sheet while bending the sheet along the bent inner peripheral face; and a second conveyance section for receiving, at its conveyance face, one side of the inverted sheet, and for conveying the sheet in the second direction, wherein the first conveyance section and the second conveyance section are formed so that the sheet is conveyed while being attracted to the conveyance faces.

A plate-making apparatus for stencil printing includes a plate feed section which feeds the heat-sensitive stencil plate that is an extended thermoplastic resin film with a predetermined thickness, and a heater to form ink-permeable openings in the film by heating the film, in which an opposite side surface to the minute recess side of the film is heated by the heater, the heater is a thermal head, a tensile stress at the time of extension internally remains in said thermoplastic resin film, an energy output of the thermal head for heating sufficiently satisfies to fuse-penetrate a thin closing portion of the minute recess, but it is restricted to the range which does not fuse-perforate a thick portion except the recess portion of the film, so that the openings are formed by the heated fused portion communicating the minute recess.

A sheet sorting and storing apparatus has a stack of bin trays which are brought open at a sheet reception position, but held close at the other position. The apparatus minimizes noises upon sheet reception with a simple mechanism, improving the efficiency of sheet sorting. The bin trays are inclined down or up depending on a position of a sheet discharge device. A desired bin tray is deviated by a deviation mechanism in an approximately horizontal direction so that a spacing in the direction of the tray inclination is enlarged between two adjacent bin trays located at the sheet reception position, while keeping constant a vertical spacing thereof. A flexible film of elastic material may be provided at the sheet entrance side of the bin trays to prevent the discharged sheet from leaping out thereof.
