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.

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 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 recording section that performs recording on a recording medium, a rotation section that sends out the recording medium by rotating a roll of the recording medium or rolls up the recording medium into a roll, and a roll diameter estimation section that estimates the roll diameter of the recording medium present in the rotation section. The roll diameter estimation section is capable of estimating the roll diameter during the recording performed by the recording section. The thus-configured recording apparatus estimates the roll diameter of the recording medium in real time during recording.
