In this embodiment, a floppy disk, for example, is used as the mass storage device 13. (cm2)...Operation Next, the operation of the CRT display device of the present invention constructed as described above will be explained by item.

(1) Input Guide The input guide here refers to display content that is displayed on the screen of the CRT 8 prior to input by the operator, and displays the type and order of data to be input by the operator.

Since input guides are prepared for each type of work that the operator intends to perform, there are multiple types of input guides. FIG. 2 shows an example in which an input guide for inn reservations used for travel handling services is displayed on the screen of the CRT 8. Input guide to operator (1)
Name indicates that the customer's name should be entered, and (2) Month, Day, and Number of Nights indicates that the date and number of nights for which the reservation is desired should be entered. The operator sees these instructions and displays an underline () on the CRT8 screen.
-) is displayed (input character device) by operating an input pen (not shown) of the electromagnetic tablet 6 to input data.

Then, the position to be input next is determined by the power sol 20.
0 indicates. Every time you enter l characters, the cursor moves to 20
The basic function of the force solen, in which 0 moves to the right, is the same as that in a normal CRT display device. In addition to the basic function of this CRT display device 100, the CRT display device 100 also functions to input characters in the first desired area of the input guide shown in FIG. It also has the function of moving to the "second choice" area and then to the "third preference" area Hekasol 200 when inputting one group of positions is completed. In addition, the operator can enter the customer's preferences in order, starting with ``first preference.''
When the user enters the "second choice" and then completes the input of the "third choice," the cursor 200 returns to the "first choice" area. (a) Calling a guide Next, calling a guide will be described.

Since input guides are prepared for each business and come in many types, it is often not a good idea to store them all inside the CRT display device 100. Therefore, in this embodiment, the necessary input guide is prepared first before starting the work.
It has a function of calling and displaying from the mass storage device 13 in the higher-level model 12 shown in the figure. In Figure 2, the input guide is displayed covering the entire screen of the CRT8, but it does not necessarily have to be that way.If there are only a few types of input, for example, the input guide can be displayed on only half the screen of the CRT8. A guide may be displayed. By calling up an input guide for another task on the remaining half screen, it is possible to perform two tasks at the same time with one device. In this mass storage device 13, input guides are often stored in the same form as the image stored in the refresh memory 10 shown in FIG. It is clear that any data format makes no difference as long as PrOtOcOl) is determined.

2 Refresh Memory FIG. 3A shows the bit configuration of the refresh memory 10 in the embodiment of FIG. 1, and FIGS. 3B to 3D explain the meaning of each bit. The text memory 10 has a one-to-one correspondence with character positions on the screen of the CRT 8, and holds 24 bits for one character position.

A detailed explanation of all of the 24 bits will be avoided here. (1) Movement of the cursor
00 is sequentially moved from the "first preference" area to the "second preference" area, the "third preference" area, and the "first preference" area to benefit the operator's human power.

This corresponds to B22 of the refresh memory 10 in FIG. 3B.
, b2l by the control program. Figure 3B to Figure 3D
, (Figures 3C and 3D are continuations of Figure 3B), the desired order bit is added for each character position, but for input items (or input fields) consisting of multiple character positions, ) is also available. (2
) Preserving the input guide when erasing the screen After displaying the input guide on the screen of the CRT 8, completing the operator input, and finishing the prescribed work, normally instruct the screen to be erased from the electromagnetic tablet 6 and erase the screen. and prepare for the next customer.

However, when the next customer's request is the same as the previous customer's request, it is better to leave the input guide in place for the following reasons. (:) It takes time to call up the input guide.

(::) Depending on the mass storage device 13, fewer accesses may extend the life of the mass storage device. During the previous work, for example, a message such as a reservation response to a travel reservation was sent to a high-end model 12 to C.
Since it is displayed on the screen of RT8, when you instruct to erase the screen, if you erase only the answer part from the higher model 12 and the part inputted by the operator first, the input guide can be preserved. That will happen.

Then, in order to select and delete only the answer part and the operator input part, the following conditions are set. (1) The answer is B23-1, Bl3 = 1 in Figure 3B, that is, this is an area where operator input is not possible and which is subject to screen erasure, and is normally blank on the CRT8 screen. It is only possible to enter the character position where B23 is 0 and the position where operator input is possible. In other words, answer information is not displayed in areas where some characters appear on the CRT 8 screen and instructions must be given to the operator. (4) Operator power is only permitted in position B23-0.

Then, all the positions of B23-0 are set to Bl3=1. By doing this, when the screen deletion instruction is given, B
If the position l3-1 is selected and deleted, the input guide is preserved and the state immediately after being called is restored.

Here, since the position B23=O indicates the position of operator input, it is necessary to write an underline when erasing the screen. As shown in Figure 5A, each page of the three-page conversion table electromagnetic tablet 6 has squares of 8 vertically x 15-120 horizontally on the left and right sides of the two-page spread. control].

A book is a collection of multiple pages arranged into a book. Here, the structure is such that each book can be attached to and detached from the CRT display device 100, and the number of the attached book and the number of the opened page are automatically read by a microprocessor. It will be done. on the other hand,
FIG. 5B shows the items of the page conversion table 4.

This page conversion table 4 is a table that stores the display and control contents (conversion data) of characters defined in each square, and in this embodiment, as shown in FIG. It is a hit and has 8 bytes. Also, it is not a good idea to memorize the conversion data for all pages of a book, so if you have only 240 items for one page and a new page is opened and you press the square, the conversion data for that page will be displayed at the top. The code is coded from the mass storage device 13 of the model 12. In addition, multiple CRTs can be installed in one high-end model 12.
When the display device 100 is connected, the mass storage device 13
Conversion data in can be shared.

0] Functions accommodated in the page conversion table The page conversion table 4 can have functions as shown in FIGS. 4 and 6.

In Figure 4, the first square has items in 8 bytes, and 2 for 1 page.
This shows a case with 40 items. Regarding 3P (space code) addition, this is an instruction bit for whether or not to add a space code when displayed using the type data key; "0" indicates not to add, and "1" indicates to add. shows. Furthermore, FIG. 6 shows the contents of the page conversion table, and the [X] marks in the figure indicate bits that have no meaning. (1) Display the number of characters specified by the number of display characters in the type data on the screen.

After displaying the characters, the cursor 200 moves to the TOP of the next input item.
(position B19-1 in FIG. 3B).
(2) Guide call input Requests the host model 12 to call the guide.

The requested input guide N6 is entered into the page conversion table 4. (3) Directly move the guide item key cursor 200 to a specific position on the input guide.

The address on the screen of the destination CRT 8 is stored in the page conversion table 4. After moving the cursor 200, the TOP of the next input item from the movement destination position (Fig. 3B
There is also a function to erase input character positions up to (Bl, -1 position). (4) Second and third desired keys Control the movement of the cursor to the first input position in the "second desired" area or "third desired" area of the input guide shown in FIG.

The explanation of the page conversion table 4 is based on the electromagnetic tablet 6.
Applicable to all types of equipment connected to

1))... [Effects of the Invention] As described above, according to the CRT display device of the present invention, C
Predetermined information to be displayed on the RT screen is stored in a refresh memory, read out from this refresh memory by a CRT control circuit in synchronization with the CRT's scanning frequency, and controlled to display on the CRT. In a CRT display device whose contents are automatically read by a microprocessor, prior to input by the operator, input guide data that instructs the operator to input the type of data and its order is called up from the host model and displayed on the CRT. Since it is displayed on the screen, the operator can visually know the input order and the type of input data.

In addition, by instructing the CRT screen to be erased using an electromagnetic tablet, it selectively erases only the answer from the higher-end model and the part manually entered by the operator, and has an input guide playback function. It is also possible,
The frequency of calling the input guide to the higher-end model can be reduced.
Additionally, cursor movement can be used to inform operator input by storing the order of operator input in refresh memory. In addition, it is now possible to equip a page conversion table for just one page of a book, and C
This has excellent effects such as making it possible to save storage space within the RT display device.
