    Abstract: A medium feeding device includes a feeding roller that is provided in a medium feeding path through which a medium is fed and that feeds a medium downstream by rotating in the forward direction in response to power of a motor, a nip roller that is provided in the medium feeding path and that nips a medium in cooperation with the feeding roller and rotates, and a controller configured to control the motor. Based on an increase in a variation value varying in accordance with a drive load of the motor, the controller controls the motor and causes the feeding roller to start a medium feeding operation.

    Abstract: A medium transport device includes a feeding roller that feeds a recording medium, a transport roller that transports the recording medium toward a recording head, and a transport motor which is a common driving source for the feeding roller and the transport roller. The medium transport device includes a power transmission mechanism that transmits power of the transport motor to the feeding roller, and a control section that controls a current of the transport motor. The control section measures a current value flowing through the transport motor during driving as a measured current value, and adds a predetermined offset value to the measured current value to set a second limit value as a limit value of the current supplied to the transport motor.

    Abstract: A recording device includes a recording head, a transport roller set, and a controller that controls a driving source that drives a transport driving roller. The controller judges whether a rear end that is an upstream end of a medium in a transport direction crosses a kicking region set in a range present downstream of a nipping position of the transport roller set in a transport direction. When the controller judges that the rear end does not cross the kicking region, the controller adjusts a feeding amount for at least one of a plurality of transport operations to be performed until the rear end reaches the kicking region in such a manner that the rear end of the medium crosses the kicking region.

    Abstract: An openable cover automatic opening mechanism 3 includes a lever 11 rotatable about a rotation fulcrum 9, a locking section 13 that is positioned at one end of the lever 11 and that maintains the openable cover 11, which is in a closed state and which receives an opening force F, in the closed state by locking with the openable cover 11, and a power receiving section 17 positioned at the other end 8 of the lever 11 for contacting the horizontally moving carriage 15 to receive power of the carriage 15. The lever 11 rotates when the carriage 15 comes into contact with and presses the power receiving section 17, and releases maintenance of the closed state of the openable cover 5 by the locking section 13.
