There is provided a transport device which transports a web-shaped substrate from a first atmosphere of a first atmosphere temperature to a second atmosphere of a second atmosphere temperature different from the first atmosphere temperature along a transport path, the transport device including a plurality of pass rollers that are disposed in the transport path and that each support the substrate, and a plurality of heaters that heat the plurality of pass rollers respectively. The plurality of heaters perform heating such that the closer a pass roller is to an upstream side of the transport path, the closer a temperature to which the pass roller is heated is to the first atmosphere temperature and the closer a pass roller is to a downstream side of the transport path, the closer a temperature to which the pass roller is heated is to the second atmosphere temperature.

An elastic roller is capable of elastic deformation at low load, lightweight and low-cost, and the surface speed of the roller has been made stable. At a drawing showing the view from the side of pipe 2 and flange 3 which make up roller 1, roller 1 which has pipe 2 and flange 3 is supported by shaft 8 which is inserted therein along axis 8a of shaft 8, the situation being such that elastic deformation occurs upon being pressed downward by pressure P from pressure-applying body 11 above pipe. None of the four outermost ribs 7a disposed in outermost gap 6a between outermost ring 4a of flange 3 and middle ring 4b which is mutually adjacent thereto and toward the interior therefrom is present in the upper portion of pipe 2.

A conveyance apparatus includes a bearing rotator, an entrance rotator, an exit rotator, a first driver circuit, a downstream conveyor, a second driver circuit, and a recording medium detector. The entrance rotator receives a recording medium at a first position. The downstream conveyor receives the medium at a second position. As a process of removing the medium, the first driver circuit starts rotation operation after the second driver circuit starts driving the downstream conveyor and rotates the rotators for not less than a period of time for the medium to be conveyed from the first position to the second position. The second driver circuit continues driving the downstream conveyor for not less than a period of time for the medium to be conveyed from the second position to a position at which the medium is detected after the rotation operation of the first driver circuit is stopped.

A sheet separation device separates a non-bonding portion of a two-ply sheet in which two sheets are overlapped and bonded together at a bonding portion of the two-ply sheet. The sheet separation device includes a winding roller and a gripper. The winding roller rotates and winds the two-ply sheet to separate the two-ply sheet. The gripper is disposed in the winding roller and configured to grip a gripped portion of the two-ply sheet at one end of the two-ply sheet without abutting a tip of the gripped portion at the one end of the two-ply sheet on a member.

A recording device includes a recording head, a transport roller set, and a controller that controls a driving source that drives a transport driving roller. The controller judges whether a rear end that is an upstream end of a medium in a transport direction crosses a kicking region set in a range present downstream of a nipping position of the transport roller set in a transport direction. When the controller judges that the rear end does not cross the kicking region, the controller adjusts a feeding amount for at least one of a plurality of transport operations to be performed until the rear end reaches the kicking region in such a manner that the rear end of the medium crosses the kicking region.

A sheet pasting device EA includes: a sheet feed unit 10 that feeds an adhesive sheet AS; and a press unit 20 that has a press roller 25 for pressing the adhesive sheet AS against a work WK and that pastes the adhesive sheet AS on the work WK by pressing the adhesive sheet AS against the work WK moving relative to the press roller 25, the press unit 20 bringing the press roller 25 into contact with an attachment surface WK1 of the work WK to displace the press roller 25 and rotating the press roller 25 on the attachment surface WK1, at a stage before pressing the adhesive sheet AS against the work WK using the press roller 25.

Provided is a paper feeding roll that prevents paper transportation failures over a long time. A paper feeding roll 10 is provided with an axial body 12 and an elastic layer 14 formed on an outer periphery of the axial body 12. The circumferential surface of the elastic layer 14 has a plurality of projections 16 forming surface unevenness. Each projection 16 of the plurality of projections 16 is shaped such that a position X of a distal-end part preceding in an opposite direction to a paper feeding direction precedes, in the opposite direction to the paper feeding direction, a position Y of a base-end part preceding in the opposite direction to the paper feeding direction.
