Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an output device, and particularly to an output device that outputs high-quality characters.

[Prior Art] Conventionally, this type of device outputs high-quality characters at the same position even when outputting high-quality characters, so that very high-quality characters could not be obtained.

[Problems to be Solved by the Invention] The present invention provides an output device that eliminates the drawbacks of the conventional example and outputs high-quality characters.

[Means for Solving the Problem] As a means for solving this problem, the output device of the present invention is an output bag that develops input information into a dot pattern and outputs it. A storage means for storing a dot pattern in the form of at least two dot patterns constituting the output dot pattern, and an output means for outputting the at least two dot patterns stored in the storage means by a predetermined amount while outputting the at least two dot patterns. .

[Operation] In this configuration, the output means outputs at least two dot patterns constituting the output dot pattern stored in the storage means while moving them by a predetermined amount.

[Example] An embodiment of the present invention will be described with reference to FIGS. 1 to 4.

FIG. 1 is a block diagram showing the configuration of the main parts of the output device of the embodiment. Note that this embodiment will be described based on a recording device as an example of an output device.

In FIG. 1, 1 is data from a host device such as a computer as serial or parallel data based on a predetermined method.
This is an interface unit that converts recorded data to be transferred into a format that can be processed by the control unit 3. The recording data transmitted from the host is stored in the RAM 9, which also serves as a buffer memory, an image buffer, and the like. The control section 3, which is composed of a microcomputer element, etc., receives data from the host device in response to operation input from the display operation section 2, and stores it in the RAM.
The data stored in 9 is sequentially recorded using the recording mechanism 4. Note that the control unit 3 performs control according to a processing program stored in the ROM 8. Further, reception of the data transfer buffer memory from the host device is performed by the interface unit 1 in parallel with the recording process. The recording mechanism 4 includes a recording head 5 made of a predetermined method such as an inkjet method or an impact method, and a carriage motor 6 that reciprocates a carriage on which the recording head 5 is mounted in the lateral direction of the recording medium.
Line feed motor 7 that moves the recording medium in the vertical direction
It consists of

FIG. 2 shows a recording section of a serial type recording device.

The recording medium 11 is backed up by the platen 12, guided by its circumferential surface, and conveyed in the direction indicated by the arrow. The illustrated platen 12 also serves as a conveying roller that is rotationally driven via a platen shaft 13 by a line foot motor shown in FIG. In front of the platen 12, a guide shaft 14 and a guide rail 15 are installed in parallel, and the carriage 16 is guided and supported by these guide shafts 14 and guide rails 15, and is moved in the direction of arrow B by the carriage motor 6 in FIG. Driven back and forth. A recording head 17 is mounted on the carriage 16, and the recording head 17 is driven to record on the recording medium 17 synchronously or asynchronously with the movement of the carriage 16.
Recording will be performed in step 1. The recording apparatus shown in FIG. 2 is of a wire dot type, and an ink ribbon cassette 18 for impact transfer is mounted on a carriage 16.

FIG. 3 is a processing flowchart of the output device of the embodiment.

FIG. 4 is an example of output output by the output device of this embodiment.

To simplify the explanation, assume that the number of output paths is m=2, the minimum horizontal distance between output dots is d, and the minimum vertical distance is straddle. The operation of the output device of this embodiment will be described below with reference to the drawings.

In FIG. 3, M is a register that stores the number of output paths;
N is an output counter, and the RAM 9 may be used or it may be provided within the control unit 3. First, in step S1, a register M that stores the number of output passes is cleared. In step S2, it is determined whether the command from the host machine (not shown) or the designation from the operation display unit is high quality output.
If high-quality output is not specified, the process moves to step S4, and if it is specified, the process moves to step S3, where m, the number of high-quality outputs, is set in register M, and output counter N is cleared.

Next, in step S4, image development is performed so that output data (characters) from a host machine (not shown) can be output.At this time, the image development process changes depending on the output counter N. In step S5, the output data processed in step S4 is output. In step S6, it is determined whether high-quality output is to be performed based on the value of register M set in steps S1 and S3, and if the output is not high-quality, the process proceeds to the next process without executing steps S7 to Stt. and transition. When the output is of high quality, the process moves to step S7 and the output counter N is counted up. In step S8, it is determined whether or not the output counter N has become the same value as the number of output passes m. If they are the same, the process moves to step Sll, where the paper is moved in the opposite direction by the distance ÷ mx (m-1). 8 to prepare for the next data and proceed to the next process.

On the other hand, if the output counter N is different from the output path number m, the process moves to step S9, and the output counter N moves the next bus position 8 shifts to the right of the first output starting position 100 (r3! II 4x becomes d x N/m)
. Next, in step S10, the paper is fed by a value 1/m obtained by dividing the value of the minimum vertical position in the paper feeding direction (usually the dot opening fi of the head) by the number of output passes m, and the process moves to step S4. , repeat until the value N of the output counter becomes equal to m.

In the case of mw2, the horizontal direction is d/2, the vertical direction is sentence/2, and as shown in Figure 4(d), the output of the second pass is shifted to the right by a half dot with respect to the output of the first bus. It will take 8 shifts to output the data.

FIG. 4(a) shows the output data of the first bus, FIG. 4(b) shows the output data of the second pass, and FIG. 4(C) shows the output result of high quality characters. A similar result can be obtained even if the moving direction is moved not only to the right but also to the left in step S9 of FIG.

Also, in step SIO, the same result can be obtained even if the paper feed direction is reversed.Because of 0 or more, even when -1m=2, the output of the second pass is lower right, lower right, compared to the output of the first bus. It is possible to select one of four locations: upper right, lower left, and upper left.

Note that the movement may be performed only up and down, or only left and right.Furthermore, in this embodiment, a recording device that records a pattern on a recording medium is assumed as an output device, but the technical idea of the present invention This can be applied not only to recording devices but also to display devices and the like.

As explained above, when outputting high-quality characters, output is performed multiple times, and the output position is set horizontally by d /
By outputting the characters by shifting them by l/m in the vertical direction, it is possible to output characters of higher quality.

[Effects of the Invention] According to the present invention, it is possible to provide an output device that outputs high-quality characters.
