Abstract

PURPOSE:To obtain an output apparatus capable of discriminating whether the previous printing and the current printing are different or the same, by a method wherein input information is converted to output pattern information which is, in turn, outputted according to an indicated format and output data is operated in a predetermined unit to be determined in a numerical value. CONSTITUTION:A paint memory 26 is constituted of a character pattern 31, a character pitch 32 and a line pitch 33, and a pattern output part 27 reads a dot pattern from the start address of the paint memory 26 at every number of the printing elements of a dot printer part, for example, at every 8 bits to drive the dot printer part 28. At the same time, the dot pattern is also read to be applied to a pattern data adding part 29 which in turn performs addition by the addition order from a control part 21 outputted in synchronous relation to the reading of the dot pattern. The data corresponding to one page is successively added and the total addition value is displayed on the display part 19 of CRT in a page unit. Therefore, an operator can know whether the previous output format and the current output format are different or the same not by a visual sensation but by a numerical value.

Description

[Detailed Description of the Invention] Industrial Application Field 1 The present invention converts human power information into corresponding output pattern information and outputs it, and also confirms the output data as a numerical value.
The present invention relates to an output device that can distinguish between the different and the same.

[Prior Art] Conventionally, this type of output device does not have a means to handle output data as numerical values, so output results may vary due to subtle differences in the output environment, such as character pitch, line pitch, and font pattern used. It was difficult to discover the differences between the two. Therefore, even if the prints are thought to be of the same format, the actual print results often differ.

[Problems to be Solved by the Invention] Therefore, the present invention is proposed to eliminate the above-mentioned drawbacks of the conventional example, and its purpose is to provide an output that can distinguish between the previous print and the current print. The goal is to propose a device.

[Means for Solving the Problem] As a means for solving this problem, for example, the functional block diagram of the output device of the embodiment shown in FIG. , an output section 50 as an output means, a recording section 60, and an addition section 70 as an arithmetic means. Print data sent from an external post computer 10 or the like is developed into actual output pattern information by a pattern development section 30 under the control of a control section 20. The output pattern information developed in this way is written into the memory 40. That is, image data similar to the actual print result is constructed on the memory 40. Output pattern information is read from this memory 40 by an output section 50 and recorded by a recording section 60. In this embodiment, a wire dot head is used in the recording section 50, and output pattern information is read out from the memory 40J in units of 8 dots, for example, and this output pattern information is output to both the addition section 70 and the recording section 60. The adding section 70 adds up the output pattern information, and displays the added value for one page on a display section 80 such as a CRT.

In this configuration, the character font, character pitch, line pitch, etc. that make up the print format are patterned as image data on a page-by-page basis, and are digitized and compared by the calculation unit, so that differences in print formats can be evaluated numerically. That's how you can tell.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[Block diagram of output device (Figures 2 and 3)] In Figure 2, the character code to be printed, the control code such as character pitch, line pitch, etc., the file name storing the print information, and its The number of pages is transmitted from the host computer 1 to the output device 2, such as a dot printer.

These print data are written into the paint memory 26 under the control of the control unit 21 in a one-to-one correspondence with the page to be actually printed.
5, it is expanded into pattern information.

Therefore, as shown in FIG. 3, the paint memory 26 contains image data corresponding to an example of an actual printed image.

In FIG. 3, 31 is a character pattern written in the paint memory 26, 32 is a character pitch created according to a character pitch code, and 33 is a line pitch created according to a line pitch code. The pattern output section 27 reads out the number of printing elements of the dot printer section 28, for example every 8 bits, from the start address of the paint memory 26 having such a memory configuration, and drives the dot printer section 28.

At the same time, the dot pattern is also read out to the pattern data adding section 29, and the control section 21 outputs it in synchronization with this.
Addition is performed according to an addition command from. One page's worth of data is sequentially added, and the total added value is displayed on a display section 19 such as a CRT on a page-by-page basis. Therefore, the operator can know the difference between the previous output format and the current output format not by visual sensation but by numerical values.

The above explanation has been made according to the block diagram shown in FIG.
, a ROM 33 that stores the processing program shown in FIG.
Since it is controlled by the RAM 24, which provides temporary data storage and a working area for the CPU 22, the control operation will be explained next.

[Explanation of Operation of Control Section (FIG. 4) FIG. 4 is a flowchart illustrating the operation of the control section 21.

When control starts, in step 1 the file number and page number sent by the host computer 1 are read, and in step S2 the character code forming the core of the print data is received. Next, in step S3, character pitch, line pitch,
Read format control information that specifies the type of character font. According to the format control information in step S4,
Dra based on the pattern development section 25 in Stella 7/S4]・
The pattern is developed, and in step s5, writing is performed on the vent mark 26.

When one page's worth of print data is written to the print pattern 26, the CPU 22 instructs the pattern output section 27 to read out 8 bits at a time (step S6).
. Simultaneously, an addition command is issued to the pattern data addition section 29 in synchronization with this (step S7). Next, control step S
Proceed to step 8 and see if the 8th sale of paint memory 26 has ended.

If the process is not completed, control is returned to step S6, and 8 bits at a time are sequentially read from the paint memory 26 and added. When the reading of the paint memory 26 is completed in step S8, the CPU 22 reads the added value for 1 base from the pattern data addition section 29 in step s9, and in step SIO the CPU 22 reads the RA value specified by the file name and page number in step SIO.
The additional value is registered in the table of M, and the display routine St
Execute t and end the process. Therefore, the operator can numerically evaluate the differences between the previous print result and the current print result from the displayed results.

Furthermore, if the numerical evaluation is performed when writing from the pattern development section 25 to the paint memory 26, printing in different print formats can be prevented in advance.

As described above, according to this embodiment, by converting input information into a pattern and making it possible to display it as a numerical value,
By checking the numerical value, it is possible to guarantee that the previously outputted result and the currently outputted result are exactly the same.

[Effects of the Invention] As described above, the present invention has the effect of being able to determine whether the previous output data and the current output data are different.
