Abstract

PURPOSE:To facilitate the attachment and detachment of only an ink tank, by forming a communication path to the ink tank so as to insert an ink film forming plate into said path by moving said ink tank to one direction. CONSTITUTION:An air vent 30 and a communication path 31 are formed to the upper surface of an ink tank 26 having an almost L-shaped configuration and the connection plate 32 integrally formed to the lower part of an ink film forming plate 21 is inserted into the communication path 31 in a water-tight and freely detachable state. When a magnetic coil is excited, the magnetic ink of the ink tank 26 is attracted and supplied into a magnetic slit 22, where the leading end of a needle 16 is positioned, from an ink passage orifice 33.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field of the Invention The present invention relates to dot printers using magnetic to r-zinks.

Technical background of the invention and its problems Conventionally, in dot printers that print using several IM needles, magnetic ink is applied to the tips of the needles.
By selectively driving the needle and bringing its tip into contact with or close to the recording paper, the magnetic ink is deposited in a circular pattern without generating an impact force, and printing can be performed with low noise. = (S'7k, Ink 119: By forming the ink II!,'

Something - C foot). Therefore, in order to make such a JJ inquiry, 1) Remove the tank and clean it, but it is necessary to replace it with a new one. However, since the ink tank is integrated with the print head and the ink tank, the print head must be removed from the carriage before it can be removed.

The printing machine must be disassembled, and the ink tank can be removed without a cone.

Purpose of the Invention The present invention provides an ink tank that can be easily replaced even when the magnetic ink becomes viscous or solidified due to long periods of non-use. The purpose is to provide one printer.

1. Summary of the Invention This invention forms a communication path in which the ink model 1 is inserted by moving the ink tank in one direction, so that it is easy to remove only the ink tank. Because of this, if the ink is not used for a long time, the viscosity of the magnetic ink may become high or it may solidify. Therefore, it is easy to replace with a new one, so you can always use magnetic ink with the appropriate viscosity, which improves printing quality. It is configured so that it can be done.

A cylindrical ink cassette 28 is removably fitted into the fitting tube 27 in a watertight manner between its lower ends. A magnetic interconnector 29 is housed in this infrastructure cassette 1-28. Next, an air hole (O) is formed on the upper surface of the ink tank 26 in close proximity to the fitting tube 27, and a communication path 1 is formed from the right side to the right side of the second side.

The width of this communicating path 31 is the same as the thickness of the ink film forming plate 21, which is determined by the J method.

In this way 1. The tank tank 26 holds the print head 6.
Since the ink tank 26 can be removed without removing it from the nozzle 5 or without removing the tank remover f1 2/I from the print head 6, the ink tank 26 can be easily removed.

Moreover, since the ink tank 26 is removed from the left side, where other parts of the printer are not located, it is extremely easy to remove the ink tank 2G.

In this way, since the ink tank 2G can be easily removed, even if the viscosity of the magnetic ink 29 in the ink tank 26 becomes high or solidifies, the ink tank 26 can be removed easily. It is easy to replace it with a new one] (
Since the use of magnetic ink 2ε1 with a viscosity of 11' always gives i'+J fil:, the printing quality can be stabilized.

Furthermore, when connecting the tank mounting base 24 and the ink tank 26, since a guide 25 is formed on the tank mounting base 24, the ink tank 26 can be fixed to the guide 25.

Effects of the Invention As described above, this invention has a communicating path in which the ink film forming plate is inserted when the ink tank is moved in one direction. This allows you to easily remove and clean the ink tank even if the magnetic ink has become viscous or hardened due to long periods of non-use, and the ink tank can be easily removed and cleaned. can be easily replaced with a new one, thereby ensuring that magnetic ink of the appropriate viscosity is always used, and
Part 44' that holds magnetic ink inside the ink tank
Since the magnetic ink is stored in the ink tank, it is possible to prevent the magnetic ink from moving when the ink tank is moved and prevent the magnetic ink from spilling from the ink tank.・It has the effect of being able to completely collect the R ink without spilling it into the ink tank.
