Abstract

PURPOSE:To select only a specific page at the side of a recorder without requiring an extracting process via an information source and to attain a dump output by providing a comparison means which compares the number of pages counted by a counting means with the number of specific pages stored in a storage means. CONSTITUTION:A storage means A stores one or more specific pages for the information desiring the dump output, and an input means B receives the information from an external information source F. The counting means C counts the pages for the information received via the means B, and a comparison means D compares the number of pages counted by the means C with the number of pages stored in the means A. Thus an output control means E outputs with dump the input information received from the source F by an amount equivalent to one page only when the means D decides the coincidence between both numbers of pages. That is, the means E skips continuously the input information until the information on a specific page is received from the source F and outputs with dump only the input information on the desired specific page to be outputted. While the information on other pages are skipped and therefore the dump output of only the specific page is facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to various recording apparatuses such as laser beam printers, and particularly to a recording apparatus having a dump output function.

[Conventional technology]

There are recording devices that have a so-called dump output function that outputs all or part of the contents of a storage device or file onto a sheet material such as paper for depacking programs and checking data.

Conventionally, in this type of device, when attempting to obtain a dump output of a specific page, the information source leaves only the information of the specific page in advance, cuts the data of other pages that should not be output as a dump, and then The recording device had to input the information for that particular page.

(Problem to be Solved by the Invention) However, in the conventional example as described above, it is actually difficult to extract only a specific page in an information source and cut data on other pages.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, an object of the present invention is to provide a recording device that can selectively extract and dump only specific pages on the recording device side without requiring extraction processing at the information source. .

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a storage means for storing one or more specific page numbers of information to be dumped, and an input means for accepting information input from an external information source. ,
a counting means for counting pages of information input through the input means; a comparison means for comparing the number of pages of the counting means with a specific number of pages of the storage means; and a comparison means determining that the number of pages matches the specific number of pages. The apparatus is characterized in that it includes an output control means for dumping and outputting one page of input information from an information source only occasionally.

(Operation) In the present invention, the counting means counts the number of pages of input information from the information source, and the counted page number is compared with a specific specified number of pages to be output, which is stored in advance in the storage means. Until the information on a particular page is entered from the source by comparing
The control means continues to skip input information, and when information on a specific page that you want to output is input, only that information is dumped, and information sent after that that is not a specific page is also skipped, so extraction at the information source is possible. Processing is no longer necessary, and only information on a specific page of information input from an information source can be easily dumped.

(Example) The present invention will be described in detail below with reference to the drawings.

FIG. 1 shows the basic configuration of an embodiment of the present invention. In this figure, A is a recording means for recording one or more specific page numbers of information to be dumped. B is an input means for accepting information input from an external information source F. C is a counting means for counting the number of pages of the information input through the input means B. D is a comparison means for comparing the number of pages in the counting means C and the specific number of pages in the storage means A. E inputs the input information from the information F source only when the comparison means determines that the number of pages matches the specific number of pages.
This is an output control means that outputs a dump for the page.

FIG. 2 shows a specific circuit configuration of a page printer according to an embodiment of the present invention. In the figure, 1 is a host computer which generates character data and control command information and inputs the information to a character generator 2 having a component 31G in the figure. Reference numeral 3 denotes an input buffer, which temporarily stores character data and control commands input from the host computer 1 as an information source. Reference numeral 4 denotes a central processing unit (hereinafter referred to as CPII) that controls the entire character generator 2 and analyzes and edits character data, control commands, etc. supplied from the host computer 1h).

Reference numeral 5 denotes a specific page number storage section (RAM) for temporarily storing a specific page number input in advance from an external input device (for example, a keyboard device) 12, and 6 a specific page number storage section (RAM) as shown in FIG. A current page recording unit (RAM) that temporarily stores the page being analyzed by the CPU 4.
When the contents of the specific page number storage section 5 (number of pages) match the contents of the current page storage section 7 (current number of pages) through comparison processing by the CPII 4, the CPII
4 transfers the data received from the input buffer 3 to the dump generator 8.

The dump generator 8 converts the data (code) received from the CPII 4 into dump character data (font) and transfers it to the output page buffer 9.

The contents of the current page storage section 7 are the specific page number storage section 5
When the content (maximum number of pages) is exceeded, CPU4
Dump generator 8 dumps data received from input buffer 3
Stop forwarding to. When the image data of the dump output reaches one page, the output page buffer 9 sends a dot image to the printer interface unit IO, and the printer interface unit IO converts the image data of the dump output into a video signal. , and sends it to the printing mechanism section 11.

FIG. 3 shows the operational procedure of the dump output control operation for a specific page in the embodiment of the present invention shown in FIG. In addition, SI S8
represents the number of steps in each process.

First, the CPII 4 receives the page number of a specific page to be printed out from the external input device 12 and sets it in the specific page number storage section 5 (S1). Set "l゛" to (
S2). When an operator issues an instruction to start output from an operator console (not shown), the host computer 1 stores character data and control command data codes in the input buffer 3 where transmission is started. After that, the CPIJ 4 reads the input data once stored in the input buffer 3 one unit at a time, 1 word or 1 line (S3).
U4 determines whether printing of all the input data stored in the input buffer 3 has been completed (S4), and makes an affirmative determination (YE).
S), the main printing process ends.

On the other hand, if the negative determination is NO in the determination process of step S4, the CPU 4 compares the contents of the specific page number storage section 5 and the contents of the current page storage section 7, and determines whether or not the contents of the two are the same. S5) If the determination is negative (NO), return to step S3. On the other hand, if the determination in step S5 is affirmative (YES), the CPU 4 converts the data read in step S3 into dump data (
The dump data is converted into dump character data) and output to the output page buffer 9 (56), and from the output page buffer 9, the dump data is recorded on paper by the printing mechanism section 11 via the printer interface IO. Then, (:PI
I4 determines whether the data read in step S3 is the end of the page (S7), and if the determination is affirmative (YES), the content of the current page storage unit 7 is incremented by "l" (Sa), and then, Control of the CPII4 returns to step S3 again. On the other hand, if the determination in step S7 is negative (NO), the process directly returns to step S3.

Through the above processing procedure, only the data of the specific page output by the operator is dumped, and when data is for other pages, only the reading operation in step S3 is repeated, so input data other than the specific page is skipped. , no output.

Note that in this embodiment, the number of pages to be specified is not only one page, but the storage area of the specific page number storage unit 5 in FIG. Of course, by comparing and determining the output of two or more specific pages, it is possible to obtain the output of two or more specific pages. Further, the input for setting a specific page may be input from an external device (not shown) to the host computer 1 through the host computer 1, or may be input from a panel switch (not shown) of the printer.

(Effects of the Invention) As explained above, according to the present invention, dump output is performed only when a preset specific number of pages matches the current page number of input data, and input data is skipped in other cases. As a result, it is possible to provide a recording device that can easily dump output only a specific page.
