A sheet feeder, which is included in an image forming apparatus, includes a sheet tray on which a recording medium is loaded, a regulating member, a link mechanism, and a guide storage. The regulating member is movably disposed to regulate a position of the recording medium loaded on the sheet tray and has guide portions having a height higher than a maximum possible thickness of a sheet stack loadable on the sheet tray and the height thereof is changeable. The link mechanism rotatably supports the sheet tray with respect to a tray storing position and a sheet feeding position. The guide storage stores the guide portions of the regulating member as the link mechanism moves the sheet tray from the sheet feeding position to the tray storing position and has a depth set to be greater than a length in a height direction of the guide portions.

An assist mechanism aids movement of a retractable unit reciprocally moving between an open and a closed position and includes a pressing device, a stopper mechanism, an engagement member, a catch portion, and a release member. The pressing device presses the retractable unit toward the open position in which the unit is extended. The stopper mechanism controls and releases retraction of the retractable unit to the closed position in which the unit is retracted, and includes a stopper and a blocking member. The engagement member is provided in the retractable unit. The catch portion engages the engagement member. The release member releases a force pulling the retractable unit when the retractable unit is moved to the closed position.

A system for transporting an object between stations, for example, from a magazine to a conveyor is provided having a rotary apparatus having two arms, wherein a first arm rocks back and forth between two positions and a second arm rotates about an axis on the first arm. The second arm can be fixedly connected to a holder having one or more suction heads for grasping the object. Preferably, the holder is arranged parallel to the object and moved in a direction perpendicular to the plane of the object as the object is removed from the magazine. Additionally, the holder is preferably displaced above the conveyor and positioned to be parallel to the conveyor, after which the holder is moved toward the conveyor in a path that is perpendicular to the plane of the conveyor. Therefore, the lateral force, shearing force, and friction exerted on the object during removal from the magazine and deposition onto the conveyor can be minimized.

A link member is rotatably supported by a lifting plate. When the lifting plate moves upward and downward, the movement of the link member is guided by a guide portion provided on a link guide hole. Before sheet feeding starts, the movement of the link member is regulated by a holding portion provided on a lower end of the guide portion so as to hold the lifting plate in a standby position against a biasing force of a feed spring. When the sheet is fed, a feed cam rotating integrally with a feed roller presses the link member to release the link member from being locked by the holding portion of the link guide hole to thereby make the link member movable along the guide portion.
