Abstract

PURPOSE:To prevent an ink ribbon from being caught by a cassette-mounting part of a printer when a cassette is removed from the printer, by providing an energizing means for rotating a payout reel in the cassette in a direction opposite to a take-up direction when take-up motion is stopped. CONSTITUTION:When a take-up reel 4 is rotated and an ink ribbon 1 is fed, rotation of a payout reel 5 rotates a brake reel 10, and a rotating force is transmitted to a friction member 12 through a friction disk 11, whereby the member 12 is rotated, and a spring 15 is stretched. At the time of stopping printing and removing a cassette 2, guide rollers 16 and a thermal head 18 are lifted up, and are contained at predetermined positions in a mounting part 8, so that a force for drawing out the ribbon 1 is released to permit the ribbon 1 to slacken. A force for pulling the reel 10 is released, and the spring 15 rotates the friction member 12 to rotate the reel 10 and the reel 5 in a direction opposite to a take-up direction, so that a slack in the ribbon 1 is taken up. Thus, the ribbon 1 is prevented from being caught by an inserting port 7 when the cassette 2 is removed.

The force pulling out the ink ribbon 1 is released and it becomes slack. As a result, the pulling force on the brake reel 10 is released, and the friction member 12 is rotated by the spring 15, causing the brake reel 10 and the supply reel 5 to rotate in the opposite direction to the winding direction, so that the state shown in FIG. The state shown in FIG. 4 is reached. In this way, when the ink ribbon 1 of the cassette 2 becomes slack, it is wound up and the ink ribbon 1 is prevented from being caught on the insertion lower when the cassette 2 is extracted.
