A sheet cutting device includes a conveyance unit configured to convey a sheet, a cutting unit configured to cut the sheet conveyed by the conveyance unit, and a conveyance belt configured to convey a cut piece cut from the sheet cut by the cutting unit in a direction orthogonal to a conveyance direction of the conveyance unit.

Sheet cutting device and printer

A device includes a winding rotary member having a cylindrical shape; a holder having a rotating member, which is provided in the vicinity of a cylindrical surface of the winding rotary member, capable of nipping and conveying the sheet; a first driving mechanism configured to rotate the winding rotary member; and a second driving mechanism configured to rotate the rotating member. The winding rotary member rotates with the sheet is nipped with the rotatable holder, whereby the sheet is wound around the winding rotary member.

Printing apparatus, sheet processing apparatus, and sheet winding device

By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is decreased by narrowing a nozzle-use range and reducing a conveyance amount over an entire printing region according to a mode used for printing an image in which the coverage of a printing medium is low due to a small number of ink colors to be used, for example, a mode used for printing a monochrome image by using a black ink dominantly in all of the density regions.

Ink jet printing apparatus and printing method

An apparatus includes a reverse unit configured to wind a sheet printed at a print unit around the reverse unit and to reverse the sides of the sheet, and the reverse unit includes a winding rotary member having a cylindrical shape, and a skew correcting unit configured to correct skewing of sheets to be led into the winding rotary member.

Printing apparatus

A printing apparatus includes a first housing at least a sheet feeding unit is provided therein and a second housing at least a printing unit is provided therein. The first housing and the second housing are individually supported on a floor. The first housing and the second housing are separable for the purpose of maintenance.

Printing apparatus and method of installing printing apparatus

An ink jet recording apparatus includes a conveyance mechanism, a recording mechanism and a control unit. The conveyance mechanism has a roller in contact with a recording surface of a sheet and conveys the sheet in a first direction. The recording mechanism records an image on a recording surface using a recording head on which a plurality of nozzles are formed over a range covering a width of a sheet to be used along a second direction crossing the first direction. The control unit, which controls the conveyance and recording mechanisms, performs an image record operation and a preliminary discharge operation onto the recording surface.

Ink jet recording apparatus

An apparatus includes a printing unit configured to print a plurality of images sequentially onto a continuous sheet while conveying the sheet, a cutter configured to cut the printed sheet into every print unit length, a drying unit configured to dry the cut sheet cut while conveying the sheet piece by piece, and at least one feeding roller situated between the cutter and the drying unit configured to apply a driving force via a torque limiter, wherein a conveyance speed of the cut sheet is larger than the conveyance speed of the sheet conveyed through the drying unit, and the feeding roller absorbs a difference of the conveyance speed according to a function of the torque limiter.

Printing apparatus and sheet processing apparatus

By suppressing deviation of dot-formation positions stemming from insufficient accuracy in conveying a printing medium due to eccentricity of a conveying roller, a printed image in which unevenness is less visible is obtained. An accumulated amount of conveyance errors is reduced by narrowing a nozzle-use range and by reducing a conveyance amount over an entire printing region according to the number of colors to be used and desired printing quality in printing an image. Moreover, the nozzles used when the nozzle-use range is narrowed are not fixed, and are switched to be used as appropriate. This prevents only certain nozzles from being used concentratedly, and allows all of the nozzles to maintain substantially the same ejection performance.

A recording apparatus for recording on a recording sheet by a recording head includes a conveying roller for conveying the recording sheet, a pinch roller in contact with the conveying roller to rotate following the conveying roller, and a sheet pressure member pivotable on the rotational shaft of the pinch roller. The sheet pressure member prevents the recording sheet from floating, hence making it possible to prevent the recording sheet from interfering with the recording head for the prevention of the disturbance that may be given to recording and damage to the recording head.

Printing apparatus which prevents floating of a recording sheet

A recording apparatus for performing a recording operation to a recording medium, conveyed by a conveyor, by using ink jet heads, and comprising an optical detector, arranged within the recording apparatus, for optically detecting desirable information and light-shielding for preventing light entering the interior of the recording apparatus from reaching the optical detector.

Light shielding provided along a paper feed path of a recording apparatus

In an electronic apparatus with a printer, there is disclosed a technique such that a printing is performed at a printing speed according to a key operation of the user and, when the user wants to rapidly see the printing result such as an arithmetic operation result or the like irrespective of the key operation, it can be printed at a high speed.

Electronic apparatus with printer

A recording apparatus, which records on a recording medium by using a plurality of recording heads, includes: a carriage for moving the plurality of recording heads in a direction crossing the direction in which the recording medium is fed; and a control section which, when at least two of the plurality of recording heads are of the same recording color, performs recording by alternately using such recording heads for a predetermined number of lines, whereby the amounts of ink consumed by the plurality of recording heads are equalized to make the ink service lives of the recording heads substantially the same.

Recording method and apparatus in which use of recording heads is

According to the present invention, a feeding mechanism comprises feeding members to contact with a recording medium and exert a feeding force to the recording medium, holding portions for holding the feeding members in predetermined positions, and a shaft rotatively supported axially at both ends thereof. At least one portion of the shaft is in a tapering configuration to make its end side portion thinner, hence facilitating the mounting of the feeding member while maintaining the strength of the shaft member. The present invention is also directed to a recording apparatus including such a feeding mechanism.

Recording apparatus with easily assemblable roller

The present invention provides an ink jet recording system having a recording means for performing the recording by discharging ink onto a recording medium, wherein an ink receiving portion for receiving ink discharged from the recording means in no association with the recording regarding the recording medium is arranged within a width zone of the recording medium and out of a recordable area of the recording medium. The present invention further provides a carriage shifting apparatus comprising a body frame, a carriage reciprocally shiftable within the body frame, and a guide member having both ends supported by both side plates of the body frame and adapted to guide the carriage, and wherein a support portion provided on at least one ends of the guide member is non-detachably attached to at least one of the side plates by fitting the support portion into a guide member supporting portion provided in the guide plate while elastically deforming the guide member supporting portion.
