Abstract

PURPOSE:To obtain a magnetic record with good resolution by using fine magnetic bodies embedded in a belt for the write head of a magnetic printer. CONSTITUTION:The write head 100 which forms a latent image on a magnetic drum 2 consists of a main head 11 made of fine magnetic bodies buried in the belt 12 rotating endlessly by a motor 13 and plural auxiliary heads 10 arrayed along a recording line. A rotary encoder 14 detects the position of the main head and a signal part magnetizes the main head reversely to form a fine latent image on the magnetic drum. Plural main heads are arranged at intervals >=2 times as large as the pitch of the auxiliary heads to speed up recording operation.

In such a magnetic printer, the conventional method for recording a magnetic latent image on a recording medium is to fix a writing head 1 provided with a Te line on a moving bed (not shown) and move the moving head in a direction parallel to the axis of the drum. There is a method in which a recording current is passed through the winding of the write head 1 in a reciprocating manner to generate a recording magnetic field to record at a predetermined location. There is a method in which a recording current is passed through an I@ line of a prescribed write head to generate a recording magnetic field, thereby recording at a prescribed location on a recording medium.

The former method, in which the write head 1 is fixed to a movable bed for recording, has the disadvantage of being unable to perform high-speed recording due to speed limitations due to the reciprocating motion of the movable head. In addition, in the latter method of arranging a plurality of write heads 1 for recording, there is a limit to the miniaturization of the write head because the magnetic head is not wound. However, there are drawbacks such as coarse recording dots and poor resolution.

Therefore, we take the AND output of the image signal R of fat in FIG. 3 and the main head position signal P of FIG. The head applied voltage Q is applied to the main node 11, and the auxiliary node 10 is excited, and a reversal magnetic field is applied to the magnetic drum 2, which is a recording medium. A magnetic latent image pattern as shown in fd+ is formed.When this formed latent image is developed with toner, toner d1 is deposited around the magnetic reversal region H as shown in Figure 3 (dl). Recording paper 9 is printed using the mechanism shown in Figure 1.
Transfer to. In addition, in FIG. 4, when writing a latent image at a location corresponding to the gear knob between the auxiliary heads, by simultaneously exciting the two auxiliary heads on both sides of the gear knob G, the small main head 11 that moves at high speed is activated.

In this way, the recording magnetic field generated by the recording signal sent to the winding I of the auxiliary head 10 once magnetizes the main head, which has a small cross-sectional area and moves at high speed, and then the magnetic drum 2 is magnetized by the lines of magnetic force radiated from the main head again. By forming a magnetic latent image on the surface, a magnetic printer with good resolution and high speed recording can be obtained. Second according to the present invention
An example of this is shown in FIG. As shown in the plan view of the same figure [al] and the side view of the same figure (bl), a plurality of main heads 11 are embedded in the hell eye 2, and the embedding interval d is the arrangement pitch of the auxiliary heads 10.
