    • The disclosure discloses a printer comprising a printing head, a take-up driving device, a take-up amount detecting portion, a constant torque control device, and a switching control portion. The take-up driving device drives a take-up portion for taking up at least a part of layers of the recording medium fed by a feeder on an outer circumference part and forming a roll. The take-up amount detecting portion detects a take-up amount by the take-up portion. The constant torque control device performs constant torque control that sets a driving torque of the take-up driving device to a constant value corresponding to an input command value. The switching control portion switches the command value in stages in accordance with an increase in the take-up amount detected by the take-up amount detecting portion associated with an advancement of the take-up by the take-up portion.
    • 本公开公开了一种打印机,包括打印头,卷取驱动装置,卷取量检测部分,恒转矩控制装置和切换控制部分。 卷取驱动装置驱动卷取部分,用于卷取由外周部分上的进料器供给的记录介质的至少一部分层并形成辊。 卷取量检测部分通过卷取部分检测卷取量。 恒转矩控制装置执行恒定转矩控制,其将卷取驱动装置的驱动转矩设定为与输入指令值对应的常数值。 切换控制部分根据由卷取部分的卷绕进给相关联的卷取量检测部分检测到的卷取量的增加而分阶段地切换命令值。
