摘要： A medium wind-up apparatus includes a reel-out motor, which is a driving source that winds up a medium, a control portion that controls the reel-out motor on the basis of a torque limit value, which regulates an upper limit of an output torque of the reel-out motor, and a reel-out side detection portion that detects a rotation speed of the reel-out motor, in which the control portion changes the torque limit value on the basis of the detected rotation speed. In this case, it is preferable that the control portion increase the torque limit value in a case in which the detected rotation speed falls below a first threshold value, and that the control portion reduce the torque limit value in a case in which the detected rotation speed exceeds a second threshold value, which is larger than the first threshold value.

摘要： A printing apparatus includes a roll-out motor that rotates a roll body supported by a roll body support unit, a feed roller pair that transports a paper drawn from the roll body, and a load measuring unit that measures a rotation load of the roll body when the roll body is rotated at a low speed and a rotation load of the roll body when the roll body is rotated at a high speed. A rotation angle range in which the roll body is rotated at the high speed is greater than a rotation angle range in which the roll body is rotated at the low speed. In one rotation of the roll body, at least a part of the rotation angle range of the roll body rotated at the low speed overlaps with the rotation angle range of the roll body rotated at the high speed.

摘要： A recording device includes a feeding roller which feeds a medium; and a groove which is provided on a downstream side of the feeding roller in a feeding path of the medium and is used for cutting the medium. The feeding roller feeds the medium to an upstream side before feeding the medium to the downstream side, after the medium is cut at a position of the groove. It is preferable that the recording device further include a control portion which controls the feeding roller so that the feeding roller feeds the medium to the upstream side before feeding the medium to the downstream side, in a case where whether or not there is a possibility that the medium is cut at the position of the groove is determined and thus it is determined that there is a possibility that the medium is cut at the position of the groove.

摘要： A recording apparatus includes a transportation section of a recording medium; a winding section of the recording medium; and a control section that controls transportation of the recording medium by controlling the transportation section and the winding section. The control section switches a threshold of a torque limit of the winding section when winding the recording medium at the winding section by synchronizing with an operation of the transportation section. According to the recording apparatus having such a configuration, an occurrence of defects is suppressed when winding the recording medium.
