Franking apparatus and printing means thereof |
摘要 |
A method and apparatus is disclosed for controlling energization of a take-up motor driving a take-up spool of used ink ribbon in thermal printing apparatus. Prior to a printing cycle, the take-up motor is energized to rotate the take-up spool until ternsion in the ink ribbon caused rotation of an ink ribbon supply spool. The take-up spool is then rotated a predetermined amount and resultant rotation of the supply spool is determined by sensing means. A function dependent upon the rotation of the supply spool is determined and used during subsequent operation of the apparatus to control energization of the take-up motor such as to wind the used riobbon onto the take-up spool with a desired amount of tension in the used ribbon.
