DRIVE BELT TENSIONING APPARATUS FOR PRINTER

摘要

A drive belt tensioning apparatus for a printer is provided having a tensioning member pivotally mounted to the printer housing so as to contact and thereby tension a drive belt about a drive shaft of a motor and a roller so as to impart rotational driving force of the motor to the roller for transporting media through the printer, a brace member mounted to the housing about a slotted arm of the tensioning member, and a locking screw fixed to the housing through the brace member and slotted arm. The pivoted position of the tensioning member relative to the housing determines the amount of tension imparted on the drive belt. The locking screw locks the pivoted position of the tensioning member. The brace member is fixedly mounted to the housing so that rotation of the locking screw is not imparted to the slotted arm during fixing of the locking screw.
