A recording apparatus includes: a feeding unit that feeds a medium placed on a medium placing unit located on a back side (&#x2212;Y) of the apparatus; a transport unit that transports the medium fed from the feeding unit; a recording unit that performs recording on the medium transported from the transport unit; a reverse path that transports the medium in a reverse direction after recording is performed by the recording unit to turn over the medium; and a feed driving motor that drives the feeding unit, wherein the feed driving motor is disposed above the reverse path.

Recording apparatus

A recording apparatus includes a return member switchable between a first orientation in which a portion of the return member overlaps a feed roller in a side view of a medium feeding path and a second orientation in which the return member is turned toward a downstream side in a medium feeding direction and does not overlap the feed roller. The return member changes an orientation thereof from the second orientation to the first orientation, thereby returning a medium to an upstream side in the medium feeding direction. When a transport roller disposed downstream of the feed roller is driven in reverse to return the medium to the upstream side and position the medium at a recording start position, the return member takes a third orientation in which the return member is raised toward the upstream side further than in the first orientation.

There is provided a recording apparatus including: a recording unit that performs recording on a medium transported in a first direction; a medium feeding unit that is positioned in a second direction opposite to the first direction of the recording unit, includes a medium supporting unit; and a medium reversing unit that reverses the medium transmitted in the second direction after the recording of the recording unit, and transmits the medium to the first direction, in which the medium feeding unit includes a first guide unit and forms a first guide surface in the downward slope toward the first direction, and a power transmission unit that transmits a driving power from a power source of the medium reversing unit to the medium reversing unit, and at least a part of the first guide unit in a vertical direction overlaps with the power transmission unit.

A recording apparatus includes a drive source, a medium receiving tray, a clutch, and a load applying unit. The medium receiving tray is configured to be driven by the drive source that is a motor having a cogging torque. The clutch is configured to idle when a predetermined amount of torque or more is applied, and provided to a power transmission pathway between the drive source and the medium receiving tray. The load applying unit is configured to apply a rotational load to a rotational body in the power transmission pathway closer to a side of the drive source than the clutch. The rotational load applied to the rotational body is set to a magnitude causing the clutch to idle before a rotational shaft of the motor rotates against the cogging torque when the medium receiving tray is operated by applying an external force to the medium receiving tray.

A recording medium feeding device includes a tray in which accommodates a recording medium, which is attachable to and detachable from a device main body including a feeding unit; a stopper that is able to switch between a regulating state in which the stopper comes into contact with a leading edge of the recording medium which is accommodated in the tray to regulate a movement of the recording medium, and a regulating release state that enables the recording medium to be fed to a feeding path; and a switching unit that is engaged with the tray to switch the stopper from the regulating state to the regulating release state, wherein the switching unit includes engaging portions that engages with the tray, and wherein the engaging portions are disposed, being separated from the stopper at the both sides of the stopper in a width direction of the recording medium.

Recording medium feeding device and recording apparatus

A sheet cassette includes a lower stage side tray that accommodates a sheet, an upper stage side tray that is slidable with respect to the lower stage side tray on an upper portion of the lower stage side tray and accommodates the sheet, and a discharged sheet tray that is slidable with respect to the upper stage side tray, is displaceable to a position to receive the sheet discharged after being recorded on, and covers an upper portion of the upper stage side tray. The upper stage side tray and the discharged sheet tray are configured to be driven by a driving unit, and the discharged sheet tray is displaced by the driving unit to a position to receive the sheet.

Recording device

A recording apparatus includes: a recording head that performs recording on a recording target medium; a driving mechanism that is capable of causing the recording head to move closer to the recording target medium or move away from the recording target medium; and a controlling section that determines driving amount for one driving operation that is performed by the driving mechanism on the basis of results of a comparison made between a first recording head movement direction that is taken or to be taken in the one driving operation and a second recording head movement direction that was taken in another driving operation that is immediately before the one driving operation and thus precedes the one driving operation.

A recording apparatus includes a recording unit, a discharge roller, a release mechanism, and a controller. The discharge roller is located downstream of the recording unit and includes a discharge driving roller and a discharge driven roller that apply a discharge force to the recording medium in a discharge direction. The release mechanism switches the discharge driven roller between a nip position, at which the discharge driven roller is brought into contact with the discharge driving roller when the recording medium is transported, and a release position, at which the discharge driven roller is spaced from the discharge driving roller when the holding tray is transported. The controller controls the transport roller, the discharge roller, and the release mechanism. The controller controls the discharge driving roller to be rotated a predetermined amount in the discharge direction before moving the discharge driven roller from the release position to the nip position.

A recording apparatus includes a lower tray that stores recording media therein, an upper tray that stores recording media therein and capable of being mounted on the lower tray, and an edge guide which is disposed on the lower tray and has a guide surface along which the sheet edge is guided, wherein the edge guide is configured such that, when the upper tray is not mounted on the lower tray, the guide surface extends to a space for storing recording media in the upper tray.

A printing apparatus includes: (A) a transport mechanism transporting a medium in a forward direction and a backward direction; (B) a head printing dots on the medium; (C) a sensor sensing existence of the medium in a non-contact manner; (D) a reversion mechanism reversing the medium; and (E) a controller controlling the sensor to sense an end of the medium when the transport mechanism transports the medium in the forward direction so as to allow the head to print the dots on the surface of the medium and controlling the sensor to sense the end of the medium when the transport mechanism transports the medium in the backward direction so as to allow the reversion mechanism to reverse the medium after the dots are printed on the surface thereof.

Printing apparatus and printing method

Printer unit for duplex printing

It is provided with a pair of carriage guide shafts, and the carriage guide shaft is made to be in sliding contact with a carriage, to realize such a concentric shaft configuration that a guide shaft part, which directly guides a reciprocating motion of the carriage, and rotation shaft parts, which are disposed on both ends thereof, were disposed so as to coincide therewith. In addition, by disposing parallel lifting device which utilized a cam mechanism and a lifting guide portion to side frames, the carriage guide shaft is configured so as to be able to obtain a predetermined lifting stroke which corresponds to a rotation angle. In addition, as synchronous drive transmission mechanism of the pair of carriage guide shafts, a gear wheel train was used.
