A medium supplying device includes a housing part configured to house a rolled medium obtained by winding a sheet, a pair of rollers disposed at a predetermined interval in the housing part, and a supplying belt with an endless annular shape provided around the pair of rollers and configured to rotate along with rotation of the pair of rollers. An outer peripheral surface of the rolled medium is supported with the supplying belt, and the supplying belt is driven into rotation to rotate the rolled medium to supply the sheet.

Medium supplying device and recording device

Printer

An ink jet printer is provided for ejecting ink droplet to paper fed into a recording section. The ink jet printer includes a print head. An ink intercept plate is disposed is disposal on a paper feed path. The intercept plate includes a print surface which has a slope which declines along the advancing paper feed direction. The print surface is disposed opposite the print head. A groove extends away from the print surface of the ink intercept plate for transporting unused ink away from the print surface.

A paper size discriminator of the size of a stacked printing paper includes a pair of members which are relatively displaced in the direction of the width of the loaded paper. A long detecting plate is attached to one of the members. The detecting plate includes a grove that is progressively stepped in a direction transverse to the width of the paper. A pin sliding in the groove is attached to the other member such that the size of loaded paper is ranked in the direction of the width by detecting the displacement of the pin. The rear end keep plate is displaced corresponding to the length of paper wherein the length of the paper is discriminated by combining output signals from first and second detecting switches.

Paper size discriminating apparatus

The telescopic structure which has a plurality of stages of sheet supporting bodies and all stages of the sheet supporting bodies are provided with top plates for covering the areas above the sheets, wherein the top plate for, at least, the last-stage sheet supporting body has of the plate member that is attached rotatably to an upper rear end part of the sheet supporting body of a stage previous to the last. The plate member can be pivoted so as to be placed on the top plate of the previous-stage sheet supporting body. The sheet feeder cassette is attached to an image forming apparatus and the top plates and such constitute the supporting body for the sheets which are discharged from the image forming apparatus.

Sheet feeder cassette

An ink jet recording method ejecting already printed sheets stacked one on top of another, wherein: a period T, necessary for ink printed on a former sheet to be fixed enough that it does not adhere to a successive sheet stacked on top of the former sheet is set; an elapsed period tn is measured from a point in time when printing of the former sheet is completed; the elapsed period is compared with a set period when the successive sheet is ejected; and if the elapsed period has not reached the set period, the successive sheet is ejected by an intermittent feeding operation in which the successive sheet slidingly contacts the former sheet at a point in time when the elapsed period exceeds the set period.

A paper discharge section for a printer having a printer body includes first and second support portions mounted on the printer body. At least one of the support portions is slidable towards and away from the other support portion. A paper pushing down portion is mounted on the printer body and positioned intermediate the support portions. The first support portion can rotate between at least a first position at which the first support portion supports a first bottom side portion of the sheet of paper and at least a second position in which the first support portion does not support the first bottom side portion of a sheet of paper. A slidable edge guide for guiding a first side edge of a sheet of paper is provided and slidable towards the other edge guide. A linkage mechanism links the slidable edge guide to the first support portion to cause the first edge guide and first support portion to slide together.

A sheet feeder assembly including and a sheet feed roller for feeding a sheet of paper in a sheet feeding direction. A sheet support is spaced apart from the sheet feed roller for supporting the sheet of paper thereon. A retaining plate is mounted on the sheet support. A hopper is displaceable between a first position spaced apart from the sheet feed roller so that the paper supported on the hopper cannot contact the sheet feed roller and at least a second position where the leading edge of the sheet of paper can contact the sheet feed roller so that the paper is urged towards the sheet feed roller.

Sheet feeder

An apparatus for conveying paper in a printer adapted to convey cut-sheet and fan-fold paper bi-directionally in a paper path. The apparatus includes a pair of paper conveying rollers positioned downstream of a print head and a pair of paper conveying rollers positioned upstream of the print head. At least one roller of one of the paper conveying roller pair has projections circumferentially extending away from the roller. The projections can be pressed against the roller to reduce the diameter and speed of the roller relative to its speed and diameter before compression to convey the paper in a first direction while preventing the formation of slack across the paper. In addition, the projections can be extended away from the roller to increase the diameter and speed of the roller relative to its speed and diameter before extension to convey the paper in a second direction while preventing the formation of slack across the paper.
