Title:
INK RIBBON FEEDER
Document Type and Number:
Japanese Patent JPH06328819
Kind Code:
A
Abstract:

PURPOSE: To provide an ink ribbon feeder capable of protecting a thermal head from a static electricity charged on an ink ribbon.

CONSTITUTION: In such a constitution wherein a take-up action of a winding spool 4 for winding an ink ribbon 2 and an rewinding action of a supply spool 3 are alternately conducted for gradually winding the ink ribbon 2 on the take-up spool 4, the ink ribbon 2 can be repeatedly used by two or more times for every fixed section and, thereby, the life of the ink ribbon 2 is extended. A pull-out path 13 longer than the winding length of the take-up spool 4 for every action is provided between a thermal head 11 and the take-up spool 4. In this manner, when the used ink ribbon 2 is rewound from the take-up spool 4, a part of the ink ribbon 2 rubbed by the used ink ribbon 2 already wound on the take-up spool 4 to have a high potential of static electricity does not reach the thermal head 11.
