A medium conveying apparatus includes a plurality of feed rollers, each feed roller rotating independently at a respective speed to feed a medium, a first sensor located on a downstream side of the plurality of feed rollers in a medium conveying direction and also in a central part in a direction perpendicular to the medium conveying direction, to detect the medium, a second sensor and a third sensor located on both sides of the first sensor in the direction perpendicular to the medium conveying direction, to respectively detect the medium, and a processor to change the speed of one of the plurality of feed rollers at least until the first sensor detects the medium when any of the second sensor or the third sensor detects the medium and the first sensor does not detect the medium within a predetermined time.

A box making machinery and a corrugated board running register method, include a feeding unit, a processing apparatus which carries out processing on a corrugated board, a running register device which adjusts the processing position of the processing device in a carrying direction of the corrugated board, and a control device which controls the running register device, wherein the control device includes a carrying misalignment amount calculation unit which calculates the carrying misalignment amount of the corrugated board from the feeding unit to a preset predetermined carrying position, and a control unit which adjusts the processing position of the corrugated board to be processed next using the running register device on the basis of the carrying misalignment amount after processing of the corrugated board has finished.

A toy device for dispensing stackable or rollable materials and related methods are described. The device has a housing arranged to contain a stack or roll of material and having a dispensing aperture. A manually actuated drive mechanism is provided by which a user can rotate a drive wheel of the drive mechanism. The drive wheel contacts and when rotated engages a portion of the material and to drive it through the dispensing aperture. A release mechanism is provided that can be moved to allow the material to be driven through the aperture. The drive mechanism can be actuated independently from the release mechanism.

A medium-feeding apparatus includes a movement detector configured to output information on movement of a medium in a first direction parallel to a feeding direction and in a second direction intersecting the feeding direction. A control unit is configured to perform abnormal feeding processing depending on the movement of the medium in the second direction. In the abnormal feeding processing, the control unit stops feeding of the medium when a first value indicating the movement of the medium in the first direction is within an allowable range and when a second value indicating the movement of the medium in the second direction exceeds a threshold, and continues feeding of the medium when the first value is outside the allowable range.

An image reading apparatus includes a medium mounting portion configured to mount a medium; a feeding means configured to feed a medium from the medium mounting portion; at least one edge guide each configured to regulate a corresponding one of at least one medium width direction edge of the medium having been mounted on the medium mounting portion; a reading means configured to read the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction; and at least one medium detection means configured to detect the medium and disposed on a further downstream side than the at least one edge guide in the medium feeding direction and further outside in the medium width direction than at least one edge regulation position for the edge regulation by the at least one edge guide.

A medium conveying apparatus includes a torque limiter provided on a rotation axis of the separation roller, a unit including a first gear, a second gear provided on the rotation axis, and a third gear provided between the first gear and the second gear. The separation roller is pressed toward a feed roller side by a force generated by the torque limiter. The first gear rotates in a direction for generating a force for separating the separation roller from the feed roller. The third gear is a two-stage gear. The number of teeth of a gear on the second gear side of the third gear is more than the number of teeth of a gear on the first gear side of the third gear.

A medium conveying apparatus includes a feed roller, a brake roller, a motor to generate a driving force, a first transmission mechanism to transmit the driving force to the brake roller through a first torque limiter, to rotate the brake roller in a direction opposite to a medium feeding direction, a second transmission mechanism to transmit the driving force to the brake roller through a second torque limiter, bypassing the first torque limiter, to rotate the brake roller in the direction opposite to the medium feeding direction, and a processor to detect media multi-feed, and perform control in such a way as to transmit the driving force to the brake roller by the second transmission mechanism and also cause the feed roller to be driven to rotate in the direction opposite to the medium feeding direction by the brake roller, when the media multi-feed is detected.

A medium feeding apparatus includes a medium supporting portion supporting a medium, a feeding roller that feeds the medium, a separation portion configured to advance and retreat with respect to the feeding roller, a path forming member that is a member positioned upstream in a medium feeding direction with respect to a contact position between the feeding roller and the separation portion, that is configured to advance and retreat with respect to the feeding roller, and that is configured to narrow a medium feeding path directed toward the contact position, and a first pressing portion pressing the path forming member toward the feeding roller, in which the path forming member displaces the separation portion in a direction away from the feeding roller when the path forming member is pushed down in a direction retreating from the feeding roller by a medium having a thickness exceeding a predetermined thickness.

The medium transporting device is arranged so as to face the feeder for feeding the medium in the transporting direction and the surface of the medium transported in the transporting direction, and detects the motion of the medium in the two-dimensional coordinate system including the first axis and the second axis. The two-dimensional sensor is provided in a state in which the first axis and the second axis are inclined with respect to the transporting direction.

A medium conveying apparatus includes a medium tray on which a medium is placed, a skew corrector that rotates the medium in such a manner that a part of an end of the medium is aligned with a predetermined line, a rotating member that contacts with the medium, and a conveyor that conveys the medium in a conveying direction, wherein the rotating member is supported rotatably on the medium tray so that, when the medium moves in a direction different from the conveying direction, the rotating member rotates following the medium.
