[Embodiments of the invention]

FIG. 1 is a diagram showing an outline of one embodiment of the present invention. 1st
In the figure, 1 is a display for an operator, 2 is a keyboard, and 3 is a small display for a customer. The operator hits the keyboard 2 to retrieve necessary information from the host computer and displays it on the display 1. Of course, data input from the keyboard can also be displayed on the display 1. The operator performs an operation to display part of the data on the screen of the display 1 on the small display 3 when necessary.

First, characteristic matters in the embodiments of the present invention will be explained. FIG. 2 is a diagram illustrating the cursor of the present invention. In Figure 2, C is the cursor on display 1, and D is the cursor on display 1.
SP indicates the display screen of the display 1, respectively. The cursor C consists of an arrow and a frame, and the converted X and Y coordinate values of the point indicated by the arrow are written in the frame. Note that the origin of the X-Y coordinates can be changed. The positioning of the cursor C can be done by dots or by character.

FIG. 3 is a diagram showing the state of the cursor C when indicating points at the four corners of the display screen DSP. The arrow of cursor C is 1 when pointing to the upper left corner of the display screen DSP.
If the lower left corner is indicated, the direction is 225 degrees; if the lower right corner is indicated, the direction is 315 degrees; and if the lower right corner is indicated, the direction is 45 degrees. In addition,
Let the X direction be 0 degrees.

It is also possible to print the data on the display screen DSP using a printer. The unit of length in the X direction on the display screen DSP and the unit of length in the X direction of the printer are different from the unit of length in the Y direction on the display screen DSP and the unit of length in the Y direction of the printer. It is different from. Therefore, the length of the printer in the X direction corresponding to one dot interval in the X direction on the display screen DSP can be set according to the printer. Then, write this converted value in cursor C. The same applies to the Y direction. By doing this, it is possible to know how many distances the point designated by cursor C is from the printing start end of the printer.

FIG. 4 is a block diagram of one embodiment of the present invention.

In FIG. 4, 4 is a mouse, 5 is a cursor display mechanism,
6 is a comparison circuit, 7 is a multiplier, 8 is a coordinate register, 9 is a conversion value register, 10 is a cursor address circuit, 11 is an address circuit, 12 is a screen memory, 13 is a display circuit, 1
4 is the start address register, 15 is the stop address register.
16 shows an address register, 16 a comparison circuit, and 17 a data transfer circuit. The mouse 4 is used to move the cursor C, and by moving the mouse 4, the contents of the cursor address circuit 10 change. Although not shown, the mouse 4 also includes a start switch,
It has a stop switch and a home setting switch. When the start switch is pressed, the contents of the cursor address circuit 10 at that time are set in the start address register 14. When the stop switch is pressed, the contents of the cursor address circuit 10 at that time are set in the stop address register 15. When the origin setting switch is pressed, the contents of the cursor address circuit 10 at that time are set in the coordinate register 8 as the origin of the XY coordinates. The cursor display mechanism 5 creates a cursor C, writes the converted X coordinate value and the X coordinate value sent from the multiplier 7 in the cursor C frame, and sends a match signal from the comparison circuit 6. When it comes, it outputs this. The comparison circuit 6 compares the address information output from the address circuit 11 with the contents of the cursor address circuit 10, and if the two match, sends a match signal to the cursor display mechanism 5.
send to The multiplier 7 receives the X output from the coordinate register 8.
The product of the relative coordinate values in the direction and Y direction and the converted value output from the converted value register 9 is generated, and the converted X and X coordinate values are sent to the cursor display mechanism 5. Coordinate register 8
outputs relative coordinate values in the X and Y directions based on the contents of the cursor address circuit 10 and the value of the origin. When the power is turned on, the origin value of the coordinate register 8 is (0, 0
), and both the X coordinate value and the X coordinate value of the cursor address circuit 10 are set to 0. The conversion value register 9 is
It stores a converted value indicating how many layers each dot interval on the display screen DSP corresponds to. The value of the conversion value register 9 becomes 1 when the power is turned on, but this value can be changed freely from the keyboard 2. The cursor address circuit 10 holds the X coordinate value and the X coordinate value of the cursor C on the display screen DSP. The address circuit 11 generates an address for the screen memory 2, and its contents are incremented by 1 every time a clock is input. Screen memory 2 is a bit map memory, and screen data output from screen memory 2 is sent to display circuit 13. Display circuit 13
sends the cursor C from the cursor display mechanism 5 and the screen data from the screen memory 12 to the display 1. Cursor C is displayed overlapping the screen data. The start address register 14 contains the cursor address circuit 1 when the start switch is pressed.
The contents of 0 are set.

The contents of the cursor address circuit 10 are set in the stop address register 15 when the stop switch is pressed. The comparison circuit 16 is the address circuit 11
The output address is the start address and stop address.
When it is within the area determined by the address, it outputs "1". The data transfer circuit 17 sends the screen data outputted from the screen memo 1/2 to the small display 3 or the printer while receiving the "1" signal from the comparison circuit 16.

The embodiment of FIG. 4 operates as follows. When the power is turned on, both the X coordinate value and the X coordinate value of the cursor address circuit 10 become O, and the cursor C is moved to the display screen D.
Pointing to the upper left corner of SP, the origin of coordinates 8 is (0,0
), and the converted value of the converted value register 9 becomes 1. The operator changes the origin value of the coordinate register 8 and the converted value of the converted value register 9 as necessary. When the operator wants to output part of the data on the display screen DSP to the small display 3 or printer, the operator specifies the beginning of the area with cursor C and presses the start switch, and then specifies the end of the area with cursor C. Press the stop switch. Then, the data of the designated area is sent to the small display 3 or the printer.

〔Effect of the invention〕

As is clear from the above description, according to the present invention, part of the data on the display screen can be easily output to another display or printer. .
