Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A medium wind-up apparatus comprising: a motor, which is a driving source that winds up a medium; a control portion that controls the motor on the basis of a torque limit value, which regulates an upper limit of an output torque of the motor; and a detection portion that detects a rotation speed of the motor, wherein the control portion changes the torque limit value on the basis of the detected rotation speed. 2. The medium wind-up apparatus according to claim 1 , wherein the control portion decreases the torque limit value in a case in which the detected rotation speed exceeds a threshold value. 3. The medium wind-up apparatus according to claim 1 , wherein the control portion increases the torque limit value in a case in which the detected rotation speed falls below a threshold value. 4. The medium wind-up apparatus according to claim 1 , wherein the control portion increases the torque limit value in a case in which the detected rotation speed falls below a first threshold value, and wherein the control portion decreases 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. 5. The medium wind-up apparatus according to claim 1 , further comprising: a reel-out portion that includes the motor and in which a roll body, around which the medium is wound, is set; and a wind-up portion that winds up the medium that is reeled out from the roll body, wherein the control portion changes the torque limit value on the basis of the detected rotation speed when the medium wound up by the wind-up portion is rewound by the reel-out portion.
