An image forming apparatus includes a reverse roller pair configured to reverse a conveyance direction of a recording medium between a first direction and a second direction, a first conveyance roller pair configured to convey the recording medium in the first direction, and a second conveyance roller pair configured to convey the recording medium in the second direction. A first distance is between the first conveyance roller pair and a reversal position in which a trailing edge of the recording medium is located when the conveyance direction is reversed. A second distance is between the reversal position and the second conveyance roller pair. An absolute value of a difference between the first distance and the second distance is an integer multiple of a circumferential length of a drive roller of the reverse roller pair or within a predetermined range from the integer multiple.

A conveying apparatus for feeding sheets into a processing apparatus is discloses which comprises a plurality of nips within which sheets are gripped and driven along a conveying direction towards the processing apparatus, each nip being defined between a respective drive wheel and an opposing reaction surface. The drive wheels are omni-wheels configured to apply a frictional force to advance the sheets in the conveying direction while permitting free movement of the sheets in a direction transverse to the conveying direction, the reaction surfaces permitting free movement of the sheets in the transverse direction, and an elongate guide is arranged on one side of the conveying apparatus, to extend generally parallel to the conveying direction, the conveying apparatus being configured to urge conveyed sheets in the transverse direction into contact with the guide. A control system is provided to move the guide generally in the transverse direction in dependence upon sensed fiducials on the conveyed sheets, to ensure correct alignment of the sheets in the transverse direction with respect to the processing apparatus.

A system and control method for determining an amount of paper product dispensed from a dispenser or remaining in the dispenser is provided. The paper product is initially loaded in the dispenser as a paper product formation, such as a roll or stack of the product. At defined intervals, a digital image of an aspect of the paper product formation in the dispenser is taken and transmitted to a digital imager processor. A feature of the digital image that changes as the paper product formation decreases in size as the paper product is dispensed is analyzed and compared with a predetermined value of the feature at a predefined size of the paper product formation to determine an amount of the paper product dispensed or remaining in the dispenser.

The invention relates to a system of spinning yarn that comprises a filament feed system configured to vary the tension applied to at least two continuous filaments before the filaments are introduced to a roving and twisted to form a yarn. The invention allows the filaments to be introduced to the roving when under tension, under no tension, or when under slack at set distances from the roving centre line by a specialized two filament guide.

There is provided a printing apparatus including: a recorder; first and second conveying rollers; a first member which includes the first conveying roller and in which the first conveying roller is supported shakably; and a second member which includes the second conveying roller. The first member includes: a roller support having: an extending part which extends in an extending direction of a rotation shaft of the first conveying roller, and first and second supports which rotatably supports first and second ends of the rotation shaft of the first conveying roller, respectively; and at least one pressing part configured to press a central area of the extending part in a pressing direction extending from the first conveying roller to the second extending roller, in a state that the first and second conveying rollers are brought into contact with each other.

A reading apparatus includes a reader, a conveyor, motors and a hardware processor. The reader reads a surface of a recording medium with an image formed. The conveyor includes rollers disposed along a conveyance path that passes through a reading area of the reader, and conveys the recording medium being laid across the rollers. The motors rotate the rollers. The hardware processor controls operations of the motors such that the rollers located farther downstream in a conveyance direction of the recording medium rotate faster. As to at least one motor of the motors, the hardware processor switches between and performs a first control to adjust a rotational speed and a second control to adjust a torque, depending on an operating state of the motor.

A conveyor includes: a receiver that detachably receives a roll-like sheet; a conveyance unit that conveys the sheet in a conveyance orientation along a conveyance surface; and a tensioner that applies tension to the sheet at a position upstream of the conveyance unit in the conveyance orientation. The tensioner includes: a frame having a groove pair extending in a first direction along the conveyance orientation; a guide having a curved surface that contacts the sheet and an engagement member pair that engages with the groove pair; a pivoting member that pivots around an axis extending in a second direction orthogonal to the first direction and parallel to the conveyance surface; a transmission member that transmits pivoting of the pivoting member to the guide; and an urging member that applies urging force including a component in the first direction to the guide.

A sheet conveyance device includes a conveyance roller pair. A skew correction roller pair conveys the sheet after contacting two nip portions, and a sheet skew is corrected in a state in which the skew correction roller pair is being stopped. The sheet having a toner image is bent by a first conveyance guide such that a sheet first surface becomes an inside surface. The sheet is bent by the first and second conveyance guides to cause the sheet first surface to be the inside surface and a sheet second surface to be an outside surface. The skew correction roller pair includes two first rotary members of a first roller. A second roller and the two first rotary members form the two nip portions. The second roller and the first conveyance guide contact the sheet first surface. The first roller and the second conveyance guide contact the sheet second surface.

There is provided an image recording apparatus having a housing having a front wall and a rear wall, and a right wall and a left wall defining an internal space of the housing, a sheet roll holder configured to hold a sheet roll, a supporting member configured to support the sheet roll, the supporting member extending in an axial direction of the sheet roll and being supported by the sheet roll holder, a sheet conveyer arranged in an internal space of the housing, the sheet conveyer being configured to convey a sheet unwound from the sheet roll, and a recording device configured to record an image on the sheet unwound from the sheet roll and conveyed by the sheet conveyer. The sheet roll holder is configured to be slidable with respect to the housing so as to be detachable from and attachable to the housing.

A recording apparatus includes a recording unit configured to perform recording on a recording medium that is a long medium, a supporting part disposed opposite to the recording unit and configured to support the recording medium, a cutting part configured to cut the long medium into a single sheet medium, a guide member configured to guide the recording medium, a winding unit configured to wind up the long medium, and a medium housing unit configured to be detachable and house the single sheet medium. The guide member is displaceable to a first supporting position in which the guide member supports the recording medium being conveyed to the medium housing unit and a second supporting position in which the guide member supports the long medium being conveyed to the winding unit, the second supporting position being located above the first supporting position.
