In a conventional magnetic printing apparatus, a recording head scans a rotating printing drum having a magnetic material on its surface to form a magnetic latent image on the drum, and then this latent image is coated with magnetic toner or ink. Once developed, this developed image can be transferred to ordinary recording paper using a pressure-type or electrostatic transfer roller, or the magnetic latent image can be transferred to a magnetic layer of each magnetized pixel body without developing the magnetic latent image. Obtain an image of magnetic toner or ink directly on recording paper using attraction force.

In such a magnetic printing device, print quality, particularly resolution, depends primarily on the size and pixel density of a magnetized pixel body or pixel that is magnetized by a recording head. In the normal magnetic printing method using current recording heads, it is necessary to reduce the size of the magnetized pixel body and increase the pixel density.In other words, the distance between the pixel points, especially in the direction transverse to the rotational direction of the drum, that is, in the drum axis direction, is reduced. There are limits to shortening the interval. This is because it is currently technically and economically difficult to keep the width of the rad core for each shielded record below a certain limit. Therefore, each recording head core with the minimum possible width is arranged in parallel as close as possible as a group of herad cores corresponding to the pixel points that make up a unit character, and the units composed of the rad cores are arranged in parallel as close as possible to each other. Even if the magnetic field is scanned by the recording head, the lateral distance between the magnetized pixels cannot be reduced below a certain limit because the lateral width of the rad core becomes an obstacle to this limited recording. the result,
There is a limit to the ability to clearly print fine print and dramatically improve image resolution, and therefore there has been a strong desire to shorten the horizontal spacing between pixels.

Based on the idea of repeating the operation of moving the track and performing scan conversion using multiple pattern memories, it is possible to reduce the gap between tracks and print images with high precision and high speed. The objective is to obtain a magnetic printer device that can.

Regarding the 5-point deviation, the head feed speed is selected so that when one drum rotation period is divided into recording time and head deviation time, the head deviation time is sufficiently smaller than the recording time. . For the 13-line deviation after the third rotation recording, if a feed speed that allows deviation in a sufficiently short time cannot be selected, the entire one rotation time can be allocated to head feed. This increases the recording time by 25 inches.

FIG. 6 shows a control section that generates control signals for realizing the scanning mode shown in FIG. 5. Pattern memory 603.604
are two sets of scan conversion memories, each holding one line of character patterns, and each bit in memory corresponds to one line on the drum.
It corresponds to each pixel in the row area. The 4-turn memory is divided into four parts corresponding to the areas recorded by each head, and its address consists of a line number indicating the head feeding position and a dot number indicating the position in the drum circumferential direction. Two sets of pattern notes! 7603 and 604, when one is writing (W), the other is reading (R) at the same time, and
It operates so that its role changes in synchronization with the recording of each line. The memory address is the write address counter 60
The write address specified by 5 and the read address specified by the read address counter 606 are switched by the address switching circuit 607 to become the address of each memory. Memory reading and writing and address switching are controlled by a read/write control circuit 609 so that reading and writing are performed alternately. The character nozzle memory 602 is a memory that stores all character patterns printed by the device and can read character patterns corresponding to appropriately addressed character codes at the required access speed, and is usually an IC memory. be done.

The shift register converts 4-bit parallel data into serial data. The character pattern specified by the character/code to be printed is taken out of the character pattern memory 602 and stored in the pattern memory A. As shown in FIG. 5, the data of the line corresponding to recording head 0 is read out from the pattern memory A, at least one bit at a time, in the order of the rotational direction of the drum, that is, by line scanning, and after passing through the buffer register AO, it is shifted. stored in register BO,
The signals are sequentially shifted to form line scanning signals, which are sent to recording head 0 and recorded on the drum. Corresponding areas of the recording heads 1, 2, and 3 are similarly read out sequentially and used as line scanning signals. Here, storage and shifting to the shift register is performed in synchronization with a pixel synchronization signal synchronized with drum rotation, and within one storage period to the shift register, readout corresponding to the head of the shift register and buffering are performed. Storage into registers is performed sequentially. The functions of buffer registers and shift registers solve problems related to memory access speeds, such as the fact that the memory addresses corresponding to each head are different and must all be read out within one pixel time. .

For example, in the above, the pattern memory is divided by the number of heads within one address space, but as another method,
It is possible to use four sets of memories that can each be read independently.

In that case, the data in the area corresponding to each head can be read out simultaneously, so that the bit speed of line scanning can be further increased in the above-mentioned case. Note that a buffer register is not required. Furthermore, although the number of herad cores is four in the above description, it is not limited to this. If the number of head cores is large, the recording time will decrease in almost inverse proportion to the number of head cores, but since the cost of the head and 7,000-turn memory will increase, it is generally better to combine recording speed and economic efficiency. decide.

Further, in the above description, the capacity of the main turn memory is set to be the size of one row, but the capacity is not limited to this, and it is possible to make it smaller or larger. If the size is small, for example half a line, one line can be printed by repeating the above procedure twice. However, writing the character font into the pattern memory is performed by dividing the character font into two equal parts. If the size is increased, data for two lines, for example, may be written in one pattern memory in the same way. Generally, the capacity of the 4-turn memory is determined by taking into consideration the size of the character font (for example, 5 x 7 dots for alphanumeric characters, 32 x 32 dots for Chinese characters), the number of head cores, economic efficiency, and recording speed.

In addition, although the case where character data is printed has been described above, the present invention is not limited to this, and can also be applied to graph data by writing the graph data into the pattern memory.
