A paper feeder includes a processor configured to, in a case of lowering a paper feed tray on which paper is placed in an accommodation section that accommodates paper and replenishing paper, the paper feed tray being controlled to be raised/lowered in a case of replenishing paper, control a lowering amount of the paper feed tray according to a number of sheets of paper to be replenished.

An accommodating device includes a device body, an accommodating unit that is movable to a supply position where a user is able to supply a medium by being pulled out from the device body in a pulling direction and of which a centroid position is located on one side surface side with respect to a center in an intersecting direction with the pulling direction, a first expanding and contracting member that expands and contracts to connect the accommodating unit to the device body so as to be able to be pulled out and is fixed to one side surface of the accommodating unit in the intersecting direction, and a second expanding and contracting member that expands and contracts to connect the accommodating unit to the device body so as to be able to be pulled out and is fixed at a position higher than the first expanding and contracting member on the other side surface of the accommodating unit in the intersecting direction.

Example feed trays for a printer are disclosed. In one example, the feed tray includes a support surface to support print media, and a guide wall coupled to the support surface. The support surface and the guide wall define a feed path for the print media into the printer. In addition, the feed tray includes a fill indicator comprising a cam rotatably coupled to the guide wall about an axis of rotation that is perpendicular to the feed path. The cam includes an extension that extends radially from the axis of rotation, and the cam is rotatable about the axis of rotation between a first position and a second position. The extension is more proximate to the support surface when the cam is in the second position than when the cam is in the first position, and the cam is rotationally biased from the second position toward the first position.

A cassette drawing-in device includes a guide portion to guide a pin protruding from a paper feed cassette, a first member in which the guide portion is formed, a second member facing the first member, a first rotation shaft, a first link rotationally supported by the first rotation shaft, a second rotation shaft provided on the first link, a second link rotationally supported by the second rotation shaft and including an engagement groove which engages the pin and slides on the pin in a direction intersecting the moving direction of the pin, and a rib on one or both of the first member and the second member. The rib slides on a side surface of the second link within a range of movement of the second link that accompanies the rotation of the first link about the first rotation shaft.

A printer extension kit that modifies a printer to receive and output longer pieces of paper. The printer extension kit includes an input extension part, an output extension part, and an output extension clip. The paper tray of a printer is extended by the input extension part allowing the printer to hold longer pieces of paper. The input extension part is attached to the paper tray of a printer. The output extension part allows a printer to output longer pieces of paper. In more detail, the output extension part prevents longer pieces of paper from falling of the catch tray of a printer. The output extension part is attached into the catch tray of a printer. The output extension clip provides another means for a printer to output longer pieces of paper. In more detail, the output extension clip is attached along the output paper catch of a printer.
