In the attached state, at least a portion of a fastening member that fixes the frame attaching portion is exposed when viewing the frame surface on the front side from the front, and the fastening member is at an attachable/detachable position.

Recording apparatus

There is provided a recording apparatus including a recording head, a support member which is disposed to face the recording head and on which a plurality of ribs for supporting a medium are formed, the plurality of ribs include a plurality of first ribs which are provided in a medium width direction and a plurality of second ribs which are positioned on a downstream side from the first ribs and are provided in the medium width direction, each of the second ribs has a guide surface for scooping up a leading edge of the medium which is fed backward, and the guide surface includes a first guide surface which is formed on each of the second ribs and a second guide surface which is formed on each of the second ribs.

A recording apparatus includes: a center frame that supports a recorder which performs recording on a medium; and at least two side frames positioned with the center frame interposed therebetween. The two side frames include: a first sub-frame to which both of a first feeder and a second feeder that feed a medium are mountable, the second feeder differing from the first feeder in the position from which to feed a medium; and a second sub-frame to which one of the first feeder and the second feeder is mountable. The second sub-frame includes a support portion that supports a power transmission unit which transmits drive power from a motor to the first feeder or the second feeder, the motor being a drive source necessary to feed a medium.

A paper guide up unit pivotally supporting a transport driven roller making contact with a transport driving roller is provided so as to be able to be displaced by the rotation of cams. The angle &#x3b1; made by a straight line passing the rotation axis line position of the transport driving roller and the rotation axis line position of the transport driven roller when viewed from the paper transport pathway side and a straight perpendicular to the paper transport direction is changed by the displacement of the paper guide up unit. Control means for controlling the displacement operation of the paper guide up unit reduces the angle &#x3b1; before the paper back end is passed through the nip point of the transport driving roller and the transport driven roller.

Recording medium transport device, recording device, and liquid ejecting apparatus

A printing medium feeding device includes: a driving roller having a roller circumferential surface coming in contact with a printing medium to apply a feeding force to the printing medium around a core line of a rotation shaft and rotating to feeding the printing medium downstream; a driven roller in contact with the driving roller and following the rotation thereof; a shaft supporting member supporting the rotation shaft at least at two supporting positions; and a regulation unit regulating a core position of the rotation shaft between the two supporting positions at which the rotation shaft is supported by the shaft supporting member, wherein the regulation unit has a pressing surface coming in contact with the rotation shaft from the upstream side or the downstream side of the rotation shaft, and wherein the core position of the rotation shaft at the position of the regulation unit is located by the pressing surface to be more downstream than a straight line passing through the core positions of the rotation shaft at the two supporting positions when the pressing surface comes in contact with the rotation shaft from the upstream side, and the core position of the rotation shaft at the position of the regulation unit is located to be more upstream than the straight line when the pressing surface comes in contact with the rotation shaft from the downstream side.

Printing medium feeding device, printing apparatus, and liquid ejecting apparatus

[Object] To discharge printed paper to a different position on a single discharge tray by providing a changing means for changing a discharge direction of paper conveyed and discharged from a paper discharge part. [Solving Means] A page printerincluding a paper discharge part for conveying and discharging printed paperonto a discharge trayis provided with an auxiliary rollerwhich is positioned near the outlet of the paper discharge part and guides the paperon its bottom side, and a roller driving partwhich is brought into sliding contact with or separated from the paperby moving the auxiliary rollerso as to be advanced or retreated to/from the bottom surface of the paper, so that the discharge positions of the paperon the discharge trayare made different from each other alternately for each printed data.

Paper discharger and ink jet recording apparatus incorporating the same

A recording head has a head face on which at least one row of dot forming elements which form dots on a recording medium is arranged in a subscanning direction thereof. A drive feeding roller extends in a main scanning direction of the recording head. A plurality of driven feeding rollers are arranged in the main scanning direction with a predetermined interval, such that the recording medium is nipped between the drive feeding roller and the driven feeding rollers to be fed to the recording head. A plurality of medium regulators are arranged in the main scanning direction with a predetermined interval which is associated with the arrangement of the driven feeding rollers. The medium regulators are opposed to the head face such that top faces define a distance between the recording medium carried thereon and the head face.

Dot recording apparatus

A printer is provided wherein printing can be executed continuously after the rear end of printing paper comes off a paper feeding roller without loss in print image quality. Specifically, the position of a point nipped by a paper ejecting roller is placed higher than the position of the top face of a record medium regulating part, and the surface of the paper located upstream of the paper ejecting roller is pressed downward. The position of the top face of the record medium regulating may be varied and backed up. As a result, the rear end of the paper being pressed downward may be caused not to touch the print head. The printer is also provided with a driving controller, that executes an interlace recording method, and the end on the upstream side of the flat top face of the record medium regulating part is located within a range of the array of dot formation elements. The drive controller records a first line of a record object using dot formation elements located at the rear end of the recording head, after the front end of the record medium reaches the end on the upstream side of the top face of the record medium regulating part and is therefore properly positioned. Subsequently, the interlace recording method is executed by repeating sub scanning, by a predetermined sub scanning distance, and main scanning by the recording head.

Dot recording device

In a printer, a bottom of an automatic paper feeder is formed by a bottom itself of a printer case; an operation lever is provided for operating a hopper and separation pawls arranged in a stacker section; a spring member is used as a changeover mechanism for a paper feed-in roller; an ink shielding portion is provided over an entire print area; the paper is discharged while forcibly urging the paper in a concave shape in which its printed surface is concaved; and a changeover is effected between a paper feeding operation and a pumping operation by a carriage at both ends of a carriage-moving area.

Printer sheet discharge method

The present invention provides a serial printer and a printing method using the serial printer. In the serial printer, assuming that the number of driven nozzles arranged in a secondary scanning direction on a print head is n and a nozzle pitch is a k-dot pitch, k is set to an integer which is no greater than n and has no prime factors greater than one in common with n. Further, secondary scanning is performed at least once at each of the start of printing and the termination of printing using a paper feeding distance of an m-dot pitch. On the other hand, secondary scanning other than the at least once secondary scanning is performed using an interlaced printing paper feeding distance of an n-dot pitch. In this case, m is an integer which is less than n and has no prime factors greater than one in common with k. Preferably, m=k.+-.j, wherein j is an integer no less than 1 and less than n.
