Abstract

PURPOSE:To simplify the printing mechanism of an ink type wire dot printer by eliminating the needs for the electric controller of ink feeding by a method in which ink is stored in the internal hollow of a damper in the rear of the head and connected to the inking portion of the printing head by an ink supply tube. CONSTITUTION:When a printing head 9 starts printing, a damper 1 is pressed by the restoring force of the head 9 to push out ink in the damper 1. Ink is passed through an ink-sending tube 2, supplied to the inking portion of the tip of the head 9, and adhered to the tips of wires 6. Since the number of hammers to be attached to the damper 1 differs to each other according to the letter pattern of printing, the amount of ink to be supplied to the head 9 is different. Since the amount of ink to be used in printing is directly proportional to the amount of ink to be supplied, proper amounts of ink can be supplied to the printing head 9.

Reference numeral 1 denotes a damper, which is hollow and made of a hard material such as polyacetal, and stores ink inside.The ink is circulated between the ink adhesion part at the tip of the print head 9 and the damper by an ink transport tube 2. is connected to.

For printing, the print head 9 moves left and right, and according to signals sent from a control circuit, the coil 4 is energized, the hammer 3 is attracted, and the print wire 6 is pushed forward.

This action causes the print paper 8 to collide with the platen 7. Moreover, after printing, the printing wire 6
The return spring 5 returns the hammer 3 to its original position while pushing it. At this time, a considerable amount of pressure is naturally applied to the damper 1. When the print head 9 starts printing, its return force pressurizes the damper 1 and pushes out the fluid ink inside the damper. The fluid ink passes through the low ink tube 2;
The ink is supplied to the ink adhesion section at the tip of the print head and adheres to the tip of the wire. Inside the ink feeder 2, there is a check valve 1.
0 is provided to supply ink in a fixed direction.

Furthermore, in the print head 9, the number of hammers that hit the dampers differs depending on the character pattern to be printed, so the amount of ink supplied to the print head also differs, and the amount of ink used for printing is directly proportional to the amount of ink supplied. Therefore, an appropriate amount of ink is supplied to the print head.

The entire damper 1 may be made of polyacetal or the like, or only the portion that is in contact with the hammer may be made of polyacetal or the like, and the other portions may be made of a different material such as gold porcelain.

ダンパ1の内部のインクがなくなった時は適宜、ダンパ
