A medium transport apparatus includes a controller that determines how many transport roller pairs disposed on a medium transport route are transporting a medium, based on detection information from detectors disposed in relation to respective transport roller pairs. Then, the controller sets a threshold to a larger value as a larger number of transport roller pairs are transporting the medium and sets the threshold to a lower value as a smaller number of transport roller pairs are transporting the medium.

Medium transport apparatus, image read apparatus, jam detection method, and storage medium

An image reading apparatus includes a feed roller configured to feed a document, a transport roller disposed downstream of the feed roller and configured to transport the document downstream; a transport motor being a drive source of the transport roller; a reading unit disposed downstream of the transport roller and configured to read the document; and a control unit configured to control the reading unit and the transport motor, wherein the control unit is configured to obtain information on a document type and an inclination detection reference value for an inclination of image data set in accordance with the document type and obtained from the reading unit, and when the inclination of the image data exceeds the inclination detection reference value in accordance with the document type, the control unit stops the transport motor.

Image reading apparatus

A medium-transporting device includes: a medium-mounting section on which a medium is mounted; a feeding unit that includes a feeding roller and that is configured to be displaced between a contact posture and a separation posture; a first restricting member that is provided downstream of the feeding roller in the transport direction and that is configured to switch between a restriction posture in which the first restricting member restricts movement of the medium and a retreat posture in which the first restricting member permits the movement of the medium; a first motor configured to generate power for rotating the feeding roller; and a second motor configured to generate power for switching a posture of the first restricting member, in which an operation of rotating the feeding roller and an operation of switching the first restricting member from the restriction posture to the retreat posture are performed in parallel.

Medium-transporting device and image reading apparatus

An image reading apparatus includes a feeding roller that includes a first roller and a second roller provided at an interval in a width direction intersecting a medium feeding direction, and feeds a sheet from a placing section; and a skew detection section that detects skew of the sheet fed from the feeding roller. Skew is corrected by giving a difference between a rotation speed of the first roller and a rotation speed of the second roller with respect to at least one of the relevant sheet detected by the skew detection section and subsequent sheets fed following the relevant sheet based on a skew amount in the sheet.

Medium feeding device and image reading apparatus

An image reading apparatus includes a lower unit, an upper unit, a flexible flat cable (FFC), a GND harness, an accommodating portion, and a widened portion. The lower unit includes a main board. The upper unit includes a sub-board and is pivotably connected to the lower unit. The FFC and the GND harness have flexibility and couple the main board and the sub-board to each other. The accommodating portion accommodates the FFC and the GND harness. A length of the GND harness in a width direction is larger than a length corresponding to a gap between the accommodating portion and the FFC.

Information processing method, information processing apparatus, and program

A medium feeding apparatus includes a mounting section on which a medium to be fed is mounted, a feeding roller configured to feed the medium mounted on the mounting section, a separation roller configured to nip and separate the medium with the feeding roller therebetween, and a regulation section disposed downstream of the nipping position between the feeding roller and the separation roller, the regulation section being configured to regulate the contact of the medium to be fed and the separation roller by coming into contact with the medium from the side of the separation roller.

Medium feeding apparatus and image reading apparatus

When consecutively feeding a plurality of media, an image scanning apparatus, according to the length of a preceding medium in a feed direction, changes the feed control for feeding the succeeding medium.

Image scanning apparatus

A pair of edge guides provided on a medium mounting section of a medium feeding apparatus each include a volume limiter spaced from the mounting surface of the medium mounting section and extending from the guide surface of at least one of the pair of edge guides in a direction intersecting the guide surface, the volume limiter including a limiting surface that limits a number of sheets mounted on the medium mounting section. The limiting surface includes a groove extending in the feed direction, at a position between a corner portion formed at an intersection of an end portion of the limiting surface in the width direction and the guide surface, and the other end portion of the limiting surface, and configured to insert at least a part of a side edge of the medium, to thereby restrict the side edge from moving in the width direction.

Medium feeding apparatus, image reading apparatus, and recording apparatus

A feeder includes a pressing section that presses a medium after a feeding force is applied on the medium in a direction in which a leading edge of the medium set in a setting section in a feeding direction abuts on an abutment section during feeding of the media by a feed roller.

Feeder, image reading apparatus and recording apparatus

A recording apparatus includes a support unit that supports a recording medium; a feed roller that feeds the medium by rotating in contact with the recording medium supported on the support unit; and a swing member that displaces the feed roller comes in contact with and separates from the recording medium, and is provided to support the feed roller and be able to swing with a swing shaft, in which the swing member includes a regulating portion that is able to attain a first state separated from the support unit in a state in which the feed roller is in contact with the recording medium, and a second state that regulates a number of recording media set on the support unit by relatively approaching the support unit more closely than in the first state in a state in which the feed roller is separated from the recording medium.

Recording medium feeding device and recording apparatus

An image forming apparatus having a print head that reciprocates along a guide rail includes a carriage on which the print head is mounted. The print head is supplied with ink through a tube from an ink cartridge that is arranged outside the carriage. The carriage includes an engaging portion that slidably engages the carriage with the guide rail, an urging portion that presses the guide rail against the engaging portion, and a base portion on which the urging portion is mounted. The urging portion includes an elastic member that is in contact with the base portion at one end thereof, and a wedge-shaped member that is connected to the other end of the elastic member and urged in a direction in which the guide rail is pressed against the engaging portion by the elastic force of the elastic member.
