Abstract: A feeder unit includes: a first tray that keeps a storage position in which the first tray is stored within the base portion and an operation position, and is provided at one end of a feeding path of a medium so as to place the medium thereon; a cover member that is openably and closeably provided to cover the first tray in the storage position when being closed or uncover the first tray when being open; and a first power transmitter that transmits power to open and close the cover member to the first tray, and the first power transmitter is configured so as to displace the first tray to the operation position with the displacement of the cover member when the cover member is switched to an open-state, and to the storage position with the displacement of the cover member when the cover member is switched to a closed-state.

Abstract: A rotation-transmitting mechanism includes a first planetary gear mechanism and a locking mechanism. The first planetary gear mechanism transmits rotational driving force to the transportation unit through a first planet gear to rotate the transportation roller when the motor rotates in a first direction, and transmits rotational driving force to the transportation unit through a second planet gear to rotate the transportation roller when the motor rotates in a second direction. The locking mechanism can lock a planetary rocking member of the first planetary gear mechanism in such a condition that rotational driving force of the motor is transmitted to the transportation unit through the second planet gear. The locking mechanism terminates locking of the planetary rocking member of the first planetary gear mechanism by engaging with the sheet in the transportation path downstream of the transportation roller with respect to the direction in which the sheet is transported.

Abstract: A recording apparatus has a paper feeder wherein single sheets of paper can be set, a paper delivery device for transporting paper fed from the paper feeder to a recorder, and a control unit for controlling operation of the paper feeder and the paper delivery device. The control unit has a skew removal execution mode of only the first sheet of paper where the paper tip is bitten into a paper delivery roller forming a part of the paper delivery device and then the paper delivery roller is reversely rotated for ejecting the paper tip for the first sheet of paper at the start of recording and then forward rotating the paper delivery roller for delivering the sheet of paper whose skew is removed to the recorder and delivering the second and later sheets of paper to a record area without executing the skew removal.

Abstract: A gap detector is operable to detect a distance between a liquid ejecting head adapted to eject liquid toward a target medium and a platen adapted to support the target medium. A circular plate is adapted to be provided on a guide shaft which is rotated together with the rotary plate to selectively determine the distance as one of a plurality of distances. The circular plate has a plurality of flags formed on an outer periphery, each of which is associated with one of the distances. A sensor is disposed in the vicinity of the outer periphery of the circular plate and operable to output a signal indicative of a passage of each of the flags in accordance with the rotation of the circular plate. At least one of intervals between the flags in a circumferential direction of the circular plate is made different from the other.

Abstract: A paper feed unit includes a hopper on which sheets are stacked and which is turned around a rotation shaft. The hopper is turned to move apart from or move to a paper feed roller. The paper feed unit has three modes: a large release mode in which the hopper is turned to be most apart from the paper feed roller, a non-release mode in which the printing sheet is abutted against the paper feed roller, and a small release mode in which the printing sheet is slightly separated from the paper feed roller, and is at a medium level between the above two modes. When a paper feeding job is still present, a state that the uppermost printing sheet is slightly separated from the paper feed roller is retained by the small release mode, whereby a swing range of the hopper is minimized.

Abstract: A paper returner is placed in the vicinity of an end portion of a hopper for stacking a plurality of sheets of paper which faces a paper feeding roller, so as to be pivotable between a first position where the paper returner constitutes a part of the paper transporting passage, and a second position where the paper returner is isolated from the paper transporting passage. A separation pad is provided on a first face of the paper returner. The separation pad has a friction coefficient which is higher than a friction coefficient of the first face of the paper returner. The paper returner is placed at the first position so that a top sheet of paper in the hopper is abutted against the paper feeding roller, and is separated from other sheets of paper by the separation pad. The paper returner is placed at the second position so that the first face of the paper returner returns sheets of paper, which are entered in the paper transporting passage-together with the sheet of paper to be fed, to the hopper.
