Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a printing device that can register image information and combine it with other print information for printing.

[Prior Art] Conventionally, there have been many printers capable of storing image information in advance in a memory in a printing device, and then combining and outputting the image information with separately sent print information. This feature is called page overlay.
It was used in such a way that the ruled lines and headings of a book, etc., were stored in advance as image information, which was then combined with print information sent from a host computer, etc., and output.

However, registration of overlay pages in conventional devices of this type requires executing various commands such as page registration commands, print position control commands, ruled line start commands, and ruled line end commands, as well as data consisting of character codes, control codes, etc. I was doing it.

Methods for registering such overlay pages can be broadly classified into the following two types.

■Purchase one that has already been created and stored in ROM.

■A figure creation program or a document input program is executed on a host computer, etc., and created by an operator's operation.

[Problems to be solved by the invention] With method ①, only a limited number of ready-made products can be obtained;
In method (2), not only is the operation complicated, but the data that can be created is limited by the functions of the program executed on the host computer or the like.

The present invention has been made in view of the above-mentioned conventional example, and is a printing device that stores image information input by an image input device in the memory of an printing device, and outputs the image information and print information by overlaying the same. The purpose is to provide

[Means for Solving the Problems] The present invention that achieves the above object has the following configuration. That is, an image input means for reading a document image and inputting image information, a first memory for inputting and storing the image information, a second memory for inputting and storing print information, and a second memory for inputting and storing the print information. The printing apparatus is provided with a printing unit that originally performs printing, and includes a unit that combines information in the first memory and the second memory.

[Function] With the above configuration, the printing device of the present invention operates to input document information from the image input means, store it in the first memory, combine the input print information and image information, and print. .

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

[Description of Printing Apparatus (FIG. 1)] FIG. 1 is a diagram showing the configuration of the printing apparatus and control system of this embodiment.

1 is a scanner for inputting image information, and 2 is a printing apparatus main body. An input interface section 3 controls the interface between the scanner 1, the host computer 11, and the printer main body 2, and receives image data transmitted from the scanner 1 and print data transmitted from the host computer 11. 4 is an input buffer that temporarily stores input data from the input interface unit 3; 5 is a central processing unit (CPU) consisting of a general-purpose microprocessor that executes the control program in ROM 5-1 and controls the entire device; -1, RAM5-2 as a work area, etc. 6 is an overlay memory that stores image information from the scanner 1 as overlay data, and 7 is a page registration table that stores various information of the overlay memory, which will be described later.

8 temporarily stores one page's worth of print information consisting of the dot image sent from the CPU 5, and outputs it to the dot printer section 9.
An output page memory 9 is a dot printer section that forms a permanent visible image on paper based on the dot information sent from the output page memory 8. Reference numeral 10 is an operation panel that controls the printing apparatus 2 and also issues instructions such as reading image information from the scanner 1. Reference numeral 11 is a host computer that transmits printing information such as character codes or control commands to the printing apparatus 2.

[Description of Page Registration Table (Fig. 2)] Fig. 2 is a diagram showing the structure of the page registration table.

22 is an identification number for identifying and searching one page of image data registered in the overlay memory 6, and 23 is the size of the page, for example, paper sizes such as A4, B4, 85, etc. are stored. has been done. 24 is an overlay memory 6 in which the image data of that page is stored.
This is the address. According to column 25, the image data with identification number 1 is A4 size, and 10 in overlay memory 6.
It can be seen that it is stored from address 00 (hexadecimal).

[Description of Page Registration Processing (Fig. 3)] Fig. 3 is a program flowchart of the page registration processing of the CPU 5 stored in the ROM 5-1.

This program is started when page registration processing is activated by the operation panel 10. At this time, the operator also inputs the paper size, identification number, etc. of the image data to be registered. First, in step S1, the registered size and identification number are input from the operation panel 10. In step S2, the amount of memory is determined based on the registered paper size read in step S1, and in step S3 it is checked whether there is enough free space in the overlay memory 6 to store the image data. If the area cannot be secured, the process advances to step S4, where error handling is performed and the page registration process is ended.

When an area is secured in the overlay memory 6 in step S3, the scanner 1 is driven to read image data in step S5. In step S6, the image data is expanded into the overlay memory 6. In step S7, it is checked whether the image data from the scanner 1 has been completed, and if it has not been completed, the process returns to step S5 and the above-described operations are repeated. When the image reading by the scanner 1 is completed, the address of the overlay memory 6 at the time of completion is stored in the RAM 5-2, etc., and is stored in the registration page table 7 in step S1.
The data such as the identification number, page size, and storage start address of the overlay memory 6 input in step 2 are registered, and the process ends.

[Explanation of overlay memory read routine (FIG. 4)] FIG. 4 shows a read routine for the overlay memory 6 stored in the ROM 5-1. This program is started when the host computer 11 instructs the dot printer 9 to overlay output information.

The page registration memory 7 is searched to determine whether the image data with the identification number specified in step SIO is stored in the overlay memory 6. It is checked in step Sll if there is data with the specified identification number, and if not, the process advances to step S12 to perform error processing such as sending a message without the corresponding data to the host computer 11.

If there is image data with the identification number specified in step Sit, the process advances to step S13, and one byte of image data is read out from the overlay memory 6. In step S14, the data is expanded into the output page memory 8. Next, in step S15, it is checked whether data reading from the overlay memory 6 has been completed, and if it has not been completed, step S13 is again performed.
Return to and perform the operations described above.

After the reading from the overlay memory 6 to the output page memory 8 is completed, for example, when print data is input from the host computer 11 via the input buffer 4, this data is developed into a dot image and output to the output page memory 8. It is logically ORed with the data of and stored in the output page memory ν8. This allows output page memory 8
stores the logical OR data of the image data in the overlay memory 6 and the dot data based on the output information from the host computer 11, and when this data is output to the dot printer section 9, the contents of the overlay memory 6 and the dot data from the host computer 11 are combined. Print data will be output overlapping each other.

FIG. 5 is a diagram showing an example of composition of an input image from the scanner 1 and print data from the host computer 11 according to this embodiment.

Reference numeral 51 indicates image information of ruled lines read and input by the scanner 1, and 50 indicates print data sent from the host computer 11. These data are printed on printing device 2.
The output data shown at 52 is inputted to , synthesized and outputted by the dot printer section 9 . As described above, according to this embodiment, it is possible to input a ruled line image from the scanner 1, combine it with print data from the host computer 11, and output the combined image.

In this embodiment, the page registration process is started by the operation panel 10, and the page read process is executed by the control command from the host computer 11, but the reverse case is also possible, and both processes can be started from the operation panel. It may be executed by an instruction or a control command from a host computer.

Furthermore, although registration of an overlay page is expressed as page registration, it is not necessary to register all of one page, and a portion of one page may be registered.

As explained above, according to this embodiment, arbitrary image information can be registered in the printing device, and it can be combined with other print information and output. Marks etc. can be registered and easily combined with print data and output.

[Effects of the Invention] As described above, according to the present invention, arbitrary image information can be input and stored, and the image information and other print information can be combined and output.
