  • Publication number: 20220204294
    Abstract: A medium feeding apparatus includes a medium mounting section forming a mounting face for mounting a medium thereon, a feeding roller configured to feed a lowermost medium among mediums mounted on the medium mounting section in a feeding direction, and a movement detection unit configured to output information related to movement of the medium in a direction along the mounting face, wherein based on detection information detected by a medium height detection unit that outputs information related to a height of the medium mounted on the mounting section from the mounting face in abnormality detection processing, when the height is less than a first threshold value, a control unit continues feeding the medium regardless of detection information detected by the movement detection unit or without obtaining detection information detected by the movement detection unit.

  • Publication number: 20220194727
    Abstract: A control unit of a medium feeding apparatus is configured to execute a fault detection process to determine that there is a feeding fault when a movement of a subsequent medium in a feeding direction is detected based on detection information of a movement detection unit within a fault detection period that is set after a trailing edge of a preceding medium is detected based on the detection information of the movement detection unit and before feeding of the subsequent medium is started, and the fault detection period set when a size of the medium in a width direction intersecting the feeding direction is a first size is shorter than the fault detection period set when the size of the medium in the width direction is a second size larger than the first size.

  • Publication number: 20220177244
    Abstract: 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.
