A dynamic tension control system is described herein for driving linear material off a roll in a controlled manner. The dynamic tension control system may include a frame, a shaft for holding a roll of linear material, a motor for driving the shaft, and a dancer tensioning control system for controlling the motor. The dancer tensioning control system may include an actuator assembly through which the linear material passes and a proximity sensor for detecting whether the actuator assembly is proximate to the proximity sensor. When the linear material is pulled from the roll, tension is created in the linear material, which lifts the actuator assembly away from the proximity sensor. The dynamic tension control system may be configured to command, based on detecting that the actuator assembly is not proximate to the proximity sensor, the motor to drive the shaft to unwind linear material from the roll.

A sheet conveying device includes: a sheet discharge roller disposed in a conveying path of sheets so as to discharge a sheet being conveyed to a sheet discharge tray; a conveying unit that conveys sheets on a side of the conveying path closer to an upstream side than the sheet discharge roller; a motor that rotates at a constant system speed during conveying of sheets to drive the conveying unit; a transmission mechanism that transmits power of the motor to the sheet discharge roller to rotate the sheet discharge roller; and a controller that controls an operation of the transmission mechanism, wherein the transmission mechanism changes a circumferential speed of the sheet discharge roller, and the controller performs speed reduction control of controlling the operation of the transmission mechanism to temporarily reduce the circumferential speed of the sheet discharge roller when a sheet is discharged to the sheet discharge tray.
