Abstract

PURPOSE:To make it possible to rapidly recover magnetic ink after printing is finished, by immersing magnetic poles opposed through a slit for arranging a large number of needles in the magnetic ink within a tank while arranging a magnet opposed to the lower ends of the magnetic poles in the tank. CONSTITUTION:When a change-over switch 36 is set to (b) when printing is finished, a magnetic ink attracting coil 16 is excited corresponding to the discharge current of a condenser 39 and the intensity of the magnetic field between magnetic poles 19 which have formed a magnetic ink layer through a slit 18 is gradually lowered. In addition, the electromagnet 26 opposed to the lower ends of the magnetic poles 19 is excited only for the time set by a timer by a battery 37 and, thereafter, by the discharge current from a condenser 40 and force for pushing up the magnetic ink 24 is gradually reduced to quietly and rapidly recover the magnetic ink in an ink tank 20 under its own wt. without diffusing the same. Therefore, the magnetic ink can be prevented from solidification caused by remaining and staying between the magnetic poles.

Technical Background and Problems of the Invention Conventional dot printers impact pressure-sensitive paper along a platen with a needle, or impact plain paper through an ink ribbon. In either case, printing is caused by collision between the needle and the platen, which causes a lot of noise.

For this reason, the magnetic poles are placed opposite to the front of the platen,
A method has been considered in which magnetic ink in an ink tank is attracted between these magnetic poles by magnetic force, a needle is passed through this magnetic ink layer, and the magnetic ink is transferred from the tip of the needle to recording paper.

However, when the magnetic field between the magnetic poles is removed at the end of printing, the magnetic ink returns to the ink tank due to its own weight, but as it diffuses, the surrounding area becomes dirty. It is inconvenient to make the ink tank's through holes larger because dirt from which the magnetic ink has evaporated can enter. In order to store the magnetic ink between the magnetic poles to a certain width due to the surface tension, it is necessary to reduce the distance between the magnetic poles, but at the end of printing, the magnetic ink between the magnetic poles is difficult to return to the ink tank, and the magnetic ink hardens on the spot. This poses a problem that makes it difficult to put it into practical use.

Dot printers that are designed to scale can be used to prevent this from happening.

In such a configuration, the selector switch (to) is connected to terminal a.
When the magnetic ink attraction coil (le) is switched to the side and the magnetic ink attraction coil (le is energized), the magnetic ink in the multi-ink tank is attracted by the magnetic flux generated between the magnetic poles σ9, a magnetic ink layer is formed along the slit H, and the needle ( The leading edge of 9) is wetted with magnetic ink G4). Therefore, by energizing the specified electromagnet (7) and sending the needle (9) toward the recording paper (to), the magnetic ink at the tip of the needle (9) contacts the recording paper (b) and forms a dot. Form. In this case, if the tip of the needle (9) lightly touches the recording paper (to), a dot is formed, so there is no collision sound as in the conventional case, and the noise is extremely low. According to this embodiment, when the tip of the needle (9) approaches the recording paper (B), the magnetic ink at the tip of the needle (9) is attracted by O magnetic poles.
It is also possible to further reduce printing noise by setting the stroke of the recording paper to a small stroke that does not make it come into contact with the recording paper.

In addition, the magnetic force of the magnetic ink suction coil is constant, and the magnetic ink (2) in the ink tank is replenished from the cartridge (21) according to the amount consumed, so it is maintained at a constant level. The level of the magnetic ink layer is also constant, and there is no situation where the magnetic ink tank does not reach the upper needle (9). Furthermore, due to the presence of the cartridge CI), there is no need to manually replenish the ink tank, which saves time and effort.
