Apparatus for applying noise reducing elements to tyres for vehicle wheels. The apparatus includes a loading station of stacks of noise reducing elements, an extraction station of noise reducing elements from each stack placed downstream of the loading station, and a conveyor placed downstream of the extraction station and extending along a predefined path. The conveyor is configured for supporting and advancing in a row the noise reducing elements extracted from the stacks which are then applied to a radially inner surface of the tyres. The extraction of each of the noise reducing elements contemplates: retaining a first noise reducing element placed at the base of a stack; raising the remaining noise reducing elements of the stack from the first noise reducing element; moving away the first noise reducing element according to a set path; and lowering the remaining noise reducing elements of the stack.

In order to downsize an overall apparatus without setting the swing angle of a swing member to be unnecessarily large, a pickup roller, which is for feeding a document disposed on a feeding tray, is supported by a pickup arm that is swingable about a rotation shaft. Depending on the rotational direction of the rotation axis, the pickup arm swings between a first position, in which the pickup roller is in contact with the document on the feeding tray, and a second position, in which the pickup roller is above and not in contact with the feeding tray. An arm member is rotated by rotation of the rotation axis after the pickup arm swings to the second position.

A pickup mechanism includes a paper feeding channel, a pickup roller assembly disposed in the paper feeding channel and projecting beyond a top of the paper feeding channel, a paper tray disposed to an upstream of the pickup roller assembly, and a guiding swing arm assembly. The guiding swing arm assembly includes two guiding swing arms mounted adjacent to and spaced from two opposite sides of the pickup roller assembly. Each guiding swing arm includes a pivoting shaft, a stopping block, and an extending arm connected between the pivoting shaft and the stopping block. The two stopping blocks of the two guiding swing arms are disposed between the pickup roller assembly and the paper tray for blocking paper. An axial direction of the pivoting shaft of each guiding swing arm is deviated from a center axis direction of the pickup roller assembly.

A sheet feeding device includes a stacking tray, a feeding portion, a first restricting member which includes a first restricting surface and a first supporting portion, a second restricting member which includes a second restricting surface and a second supporting portion, and an interrelating portion. In a state in which the first restricting surface and the second restricting surface are brought closest to each other, a part of the first restricting portion is positioned on a second restricting surface side with respect to a center line of the stacking tray, and a part of the second restricting portion is positioned on a first restricting surface side with respect to the center line.

A medium feeder includes: a path blocking member configured to rotate to switch between a blocking state that blocks a feed path for a medium fed out from a tray at a position of the guide member, and an open state that opens the feed path; and a switching unit that performs switching of the path blocking member, wherein the switching unit includes a rack configured to be displaced in a feeding direction in which a medium is fed from the tray to thereby perform switching of the path blocking member, and a pinion gear that drives the rack.
