    摘要： A medium conveying apparatus includes a driving force transmitting mechanism to transmit a driving force from a first motor to a brake roller and a pair of conveyance rollers located on the downstream side of the brake roller, and a processor to rotate the first motor forward to control so that a medium separated by the brake roller is conveyed by the pair of conveyance rollers, in a separation mode. The processor rotates the first motor backward to perform a feed operation by the brake roller and rotate the pair of conveyance rollers backward until a front edge of the medium passes through a position of the brake roller, and rotates the first motor forward to control so that the medium is conveyed by the pair of conveyance rollers after the front edge of the medium passes through the position of the brake roller, in a non-separation mode.

    摘要： A medium supply device includes a feeding unit that feeds a medium among one or more media placed on a placing table, a separating unit that is arranged to come into pressure-contact with the feeding unit, a blocking portion that is movable and blocks a space formed between the feeding unit and the separating unit in an upstream side of a nip region in a conveying direction of the medium, and a curve-forming portion that presses the medium against the feeding unit side to form a curve in a width direction of the medium.

    摘要： A medium reversing and discharging device includes a discharger that discharges a medium in a paper discharge direction from a discharge outlet, a holder that holds and reverses the medium, and a driver that moves the holder such that when a first plane along a portion of the medium in contact with the discharge outlet does not intersect with a second plane along a portion of the medium held by the holder on a downstream side in the paper discharge direction of the discharge outlet a moving speed at which the holder moves is lower than a discharge speed at which the medium is discharged from the discharge outlet.

    摘要： A medium feeding device 1 includes a separating power generating device 7 which causes a brake roller 4 to generate a rotational load in a direction counter to a conveying direction. The device 7 includes a torque limiter 17 which generates a load of a predetermined upper limit torque T1, a torque limiter 18 which is arranged in series with the torque limiter 17 on a power transmission path to the brake roller 4 and generates a load of an upper limit torque T2 smaller than the torque T1, and an electromagnetic clutch 22 which switches between connection and disconnection between the power transmission path and a bypass route which bypasses the torque limiter 18. The device 7 can change the rotational load of the brake roller 4 to the torque T1 or the torque T2 by the switching of the electromagnetic clutch 22.
