JPS63197673A - Composite head type printer - Google Patents

Abstract

PURPOSE:To markedly enhance printing speed, by assembling a plurality of printing heads in a composite type, and mounting the composite head assembly on a driving belt. CONSTITUTION:A paper is placed on a printing plate of a printer and an ink ribbon having a sufficient width for facing both of two printing heads 1 and 2 combined into a composite assembly is passed on the front side of the paper. The two printing heads 1 and 2 are supplied respectively with printing information for alternate lines, and each of the heads mechanically or thermally forms dot patterns by using a plurality of pins or heat generating elements. Thus, printing in two lines is simultaneously performed by respective printing operations of the two printing heads, so that the printing speed is doubled. It is made possible to obtain a printing speed equal to three or more times a conventional speed by combining three or more printing heads and inputting printing information for every three or more lines.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Use for Sedentary Work The present invention relates to printers used in peripheral devices such as combinators or word processors.

In particular, it relates to a multi-function printer having a plurality of print heads 'f'.

Conventional technology Conventionally, impact type or non-impact thermal transfer type printers have generally been used. It has a drive belt for moving the head left and right and a print plate that holds the paper to be printed, and the drive belt moves and the print head arbitrarily touches the paper on the print plate via an ink ribbon or the like. Dora)? I had trouble finding something to print on. Therefore, in order to increase the printing speed, in the impact type, the mechanical time required to take out and take out multiple bottles to form dots is required, and in the thermal transfer type, the physical time required to heat and transfer the multiple heating elements is required. However, there are limits to how much time can be reduced, and it is difficult to significantly increase speed.

Problems to be Solved by the Invention The object of the present invention is to solve the above-mentioned drawbacks, namely, the problem that it is difficult to take into consideration the printing speed in the Ol: rice structure. The purpose is to provide 118 to 1 printers.

Problem t - Means for Solving The present invention solves the above-mentioned problem by providing at least a drive belt and a plurality of print heads mounted on the drive belt in a composite manner. This configuration employs a configuration that has

Function Since the present invention is configured as described above, each of the plurality of print heads mounted in a composite type on the drive belt can simultaneously input print information divided into every few lines or left and right. It is possible to print different characters on the paper at the same time.

Example Next, embodiments of the present invention will be described with reference to the drawings.

Referring to FIG. 1 showing the mounting state of the print head on the drive belt according to the first embodiment of the present invention, the composite head printer of the present invention has two print heads mounted on at least the drive belt 3. 1 and 2 are fixed by fixing fittings 4 and 5 with a printing line interval between them.

Next, the operation of this embodiment will be explained. A sheet of paper is placed on the printing plate of the printer, in front of which passes an ink ribbon having a width sufficient to face either of the two combined printheads 1 or 2. Two print heads 1 and 2&:r, printing every other line are manually operated, and a plurality of respective bottles or heating elements are used to mechanically or thermally form a dot pattern. Therefore, each printing operation prints two lines at the same time, doubling the printing speed. Note that it is possible to obtain multiple times the printing speed by combining three or more print heads and inputting print information for each line. ! Figure 2 shows the mounting state of the print head on the drive belt according to the second embodiment of the present invention, and the horizontal composite is performed in contrast to the vertical two-stage composite in Figure 1. ing. In this case, two print heads 1
By selecting an interval of 2 and 2, for example, half the printing width of the printer, it is possible to divide the recording surface into left and right sides and print two gold characters at the same time. In this case, as in the first embodiment, it is also possible to combine three or more print heads to obtain a print speed several times higher.

Effects of the Invention As explained above, according to the present invention, by mounting a plurality of composite print heads on a drive belt, the printing speed can be significantly improved by 2 times or 3 times t-. There is an effect that it can be done.
