ッド１に対向する様に配置し、印字紙２をヘッドｌ。Conventionally, magnetic powder is attracted by electromagnetic means to print desired patterns such as characters, symbols, or figures on plain paper (hereinafter simply referred to as [
- Printing), as shown in FIG. 1, a magnetic head 1 such as an electromagnet capable of adjusting the magnitude of magnetic force is positioned on one side (usually the top side) of the printing paper 2, and 3 tons of magnetic powder is placed on the other side (usually the bottom side) of the printing paper 2.
A permanent magnet 4 is placed in the magnetic powder so that one end thereof faces the head 1, and the printing paper 2 is placed in the head 1.

困難であった。By inputting an appropriate control signal to the head 1 while the stored magnetic powder 3 and the permanent magnet 4 are moving relative to each other, the magnetic force is adjusted as appropriate, and normally a constant magnetic force is turned on.
, OFF control is performed), thereby attracting the magnetic powder attached to the end of the permanent magnet 4 and depositing it on the printing paper,
The toner in the magnetic powder is heated and melted to fix it on the printing paper 2 by a conventional method, and the magnetic powder is recovered. However, in this method, the permanent magnet 4
When the magnetic powder 5 is attracted from the tip of the paper and attached to the printing paper 2, an empty PJA 6 is formed after the magnetic powder 5 comes out, but normally the magnetic powder would be removed immediately by the attraction force of the permanent magnet 4. 3 flows so as to fill the gap 6 (7) The magnetic powder 3 should be prepared for the next magnetic material attraction by the herad 1, but since the magnetic material 3 does not have very high fluidity, the supply of the magnetic powder 3 to the void 6 is limited to its amount and The printing speed was insufficient, and as a result, the printing density was not constant, sometimes resulting in missing prints, and it was difficult to improve the printing speed.

A magnetic powder storage case 7 is arranged on the lower side of the printing paper 2 held horizontally at a position facing the magnetic head 1 on the upper side. Magnetic powder 3 is stored in the lower part of the case 7. ing. The upper part of the case 7 is open, and a roller 8, which is driven and rotated by a rotational axis horizontal to the opening, is provided with a part of the roller 8 protruding outside the case 7 and facing the head 1. There is. roller 8
An endless case 9 having magnetism is wound around. The case 9 is circulated through a storage section of the magnetic powder 3 in the lower part of the case 7.

る。The head 1 and the case 7 are moved in the direction of the arrow while maintaining their relative positional relationship, and the printing paper 2 is stationary. The roller 8 rotates in the direction of the arrow, causing the magnetic tape 9 to run. When the magnetic case 9 travels through the magnetic powder 3, the magnetic powder 3 is attracted to the tape surface, and the chip 19 reaches the printing position facing the roller 8 and the roller 8.
A magnetic powder layer with a certain thickness is placed on the surface of the paper.

応し得る。The tape guide 10 is used to keep the printing paper 2 parallel to the case 9t throughout its life and to make it run in the direction of the arrow. In this embodiment, the case 7, the tape guide 10, and the printing paper 2 remain stationary. Then, the head 1 is made to travel in the direction of the arrow. During operation, the tape 9 having a magnetic powder layer is caused to come to a position above the magnetic field 10 in advance by the movement of the case 9 and is held stationary, and then the magnetic force is controlled while the head 1 is moved in the direction of the arrow. As a result, the magnetic powder on the tape 9 is properly attracted. When the head 1 moves to the magnetic end S of the printing paper 2 while printing and then returns to the other end, the case 9 is made to travel the same distance in the direction of the arrow, and a new entire surface is placed on the tape guide 10. A case 9 containing magnetic powder N is supplied to O. [Effect of the present invention J] According to the magnetic powder supply mechanism of the present invention as described above, when the magnetic head moves relative to the printing paper during printing, the printing Since a fixed amount of magnetic powder is always supplied to the position, the printing density can be kept constant and the printing speed can be increased sufficiently.
