Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a hard copy device, and more particularly to a hard copy device capable of copying images from a plurality of related display devices onto the same recording paper.

Conventionally, one screen (one display device) was copied onto one sheet of recording paper.
Therefore, in conventional methods, when multiple display devices are used to display related graphs, for example, two display devices are used to perform remote control for process control in a chemical plant or the like. If one display shows the process temperature and the other displays the defective rate, when you want to copy this, you have to copy it onto separate recording papers. Also, 1
When two hard copy devices are used, there is a slight time lag (one copy), which is inconvenient when trying to see changes in time.

The present invention aims to eliminate such conventional drawbacks and make it possible to copy images from a plurality of related display devices onto the same recording paper. An example will be explained.

FIG. 1 shows recording paper recorded by the copying apparatus of the present invention; 1 is one sheet of recording paper; 2 is a display screen recorded by recording head A; 3 is a display screen recorded by recording head B; This shows a case where a temperature graph is recorded on the screen and a failure rate graph is recorded on the screen.

FIG. 2 is a block diagram of the copying apparatus of the present invention, in which 10 is a display control section into which head position information is input, 11 is a printing control section, and 12 and 13 are a display and a display address section, respectively. Note that the display control section 10 and the printing control section 11 are well known, so detailed explanations thereof will be omitted.

Next, the operation will be explained. First, the display screen and which areas on the recording paper are to be printed on each of the display screens are determined, and the printing start position data for each screen is stored in the display control section 10. Furthermore, the order in which image information is read out on the display is determined in advance. When the head position information corresponding to the printing start position data is input to the display control section 10, the display control section 10 controls the display address sections 12 and 13, and the address information is input from the display address section to the display. Then, image information corresponding to that address is read out, and the printing control section 11 outputs a printing signal corresponding thereto, drives heads A and B, and prints.

In this way, the image information is sequentially read out from the display according to a predetermined reading order, and the print control section 11 drives the heads A and B to display both the images in predetermined areas on the recording paper. The screens are copied at the same time.

FIG. 3 shows an example of a printing device used in the block configuration copying device shown in FIG. 2, in which 20 is a drum, 21 is a main scanning motor, 22 is a head moving wire, 23 is a guide rod, 24 is a rubber belt, 25 is a head A, and 26 is a head B.

In the printing apparatus shown in FIG. 3, a main scanning motor 21 rotates a drum 20 around which recording paper is wound, and a sub-scanning motor (not shown) connects heads A and B to print in line sequential order through a wire 22. Copy.

Note that although the above example has been described for the case of two display devices, the same applies to two or more displays.

Figure 4 shows an example in which images from four display devices (from display to display) are copied onto the same recording paper, and Figure 5 shows an example in which the same image is divided and displayed on four displays and copied onto the same recording paper. Here is an example.

As described above, according to the present invention, images from a plurality of related display devices can be copied onto the same recording paper.

[Brief explanation of the drawing]

FIG. 1 is a diagram showing recording paper recorded by the copying device of the present invention, FIG. 2 is a block diagram of the copying device of the present invention, and FIG. 3 is a diagram showing an example of a printing device. Figure 4 is a diagram showing an example of copying images from four display devices onto the same recording paper.
The figure shows the same image divided into four displays.
