Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field] The present invention relates to an information processing apparatus capable of moving figures displayed on a display means according to the suppression level of a key input stage.

[Prior art] Conventionally, to move the cursor using key input, the cursor was moved in a single direction of up, down, left, and right using the movement keys, and when moved in the creation direction, it was moved in two directions. I had to move it separately. Therefore, the operation is complicated and it takes a lot of time to move.

[Objective] The present invention has been made in view of the problems of the prior art described above, and an object thereof is to provide an information processing device that can freely specify the moving direction of a figure.

[Embodiment] FIG. 1 is a functional block diagram of the present invention, in which the pressing level of the input of the figure movement instruction key 101 of the key input means 100 is detected by the pressing level detecting means 110, and the figure position specifying means 1.20 is detected. When inputting from a plurality of keys at the same time, the direction of figure movement is determined based on the vector of the ratio of the pressing levels of each input key, and the figure position specifying means 130 instructs the figure position specifying means 130, and the figure position specifying means 130 instructs the display means 140 in accordance with the instruction. This indicates the position of the displayed figure.

An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 2 shows an example of a schematic configuration of the information processing apparatus of this embodiment.

In the illustrated configuration, l is a microprocessor, 2 is an address bus for specifying the storage location of each input/output memory, 3 is a bidirectional data bus used for transferring various data, and 4 is a writing bus for each memory, etc. This is a control path for transmitting control signals such as , read, interrupt reception, data setting timing instructions, etc. Also, 5 is Alphabella 1
A keyboard 6 is a keyboard controller for controlling the keyboard 5, and data inputted from the keyboard 5 is encoded by the keypad 1 controller 6, and the key code is At the same time, a processing interrupt signal, ie, an included signal, is sent to the microprocessor 1 via the control path. Further, 7 is a CRT controller, which controls an eight-blade controller 12 for a CRT display device. The display controller 9 constantly reads the character generator 10 sequentially, and displays pattern information such as characters corresponding to the read key code stored in the refresh memory 11. Display control information such as brightness, inversion, underline, blinking, etc. The processed character pattern information is supplied to the CRT display device 8 for display. On the other hand, the character generator 10 sequentially outputs, from among the stored character patterns, character patterns to be arranged in a row specified by code input such as character coat and character pattern row address, and the refresh memory 11 . Once the character code and display control code to be displayed on the CRT display device 8 are stored,
In response to display instructions from the CRT controller 7, these character codes and display control codes are repeatedly output.

Furthermore, the refresh memory controller 12
In response to instructions from the RA controller, the above-described refresh cycle for CRT display and data writing and reading from the microprocessor 1 are controlled. Reference numeral 13 denotes a read-only memory, ie, a so-called read-only memory (ROM), which stores control procedures for information processing, which will be described later, as well as various processing procedures.

Further, 14 is a ROM controller that controls reading of the ROM 13, and 15 is a random access memory (R
AM) and stores various data. For example, a column cursor register (CCR) that stores the column direction position of the cursor on the CRT 8, a row cursor register (RCR) that stores the row direction position, a keyboard buffer (KB) that temporarily stores input information from the keyboard 5, and a keyboard Right direction suppression level register (RL) and left direction suppression level register (RL) that store the suppression level of the cursor movement key on 5
LL), an upward suppression level register (UL), and a downward pressure level register (DL), as shown in FIG.
UL corresponds to the "↑" key 17, and DL corresponds to the "↓" key 18.

In addition, in the RAM 15, a right margin register (RMR) and a left margin register (L
MR), upper margin register (UMR), lower margin register (DMR), and the human keys on keyboard 5 are on the same level as the cursor discrimination table (CDT) that determines whether the input is a cursor movement key or another key. When a number of cursor movement keys are input, a movement discrimination table (i
DT).

Note that 16 is a RAM controller that controls reading and writing of data to this RAM 15.

Next, an example of a specific configuration and arrangement of the keyboard 5 is shown in FIG.

5A in the figure is a character symbol key group consisting of alphabet keys, katakana keys, hiragana keys, etc. 5B is a group of cursor movement keys that instruct the cursor to move up, down, left, and right, and the upper blade direction cursor (↑) indicates upward movement.
17. Downward cursor (↓) indicating downward movement18
, right cursor (→) 19 that instructs movement to the right.
, left cursor (←) 20 that instructs movement to the left.
It becomes more.

Note that this cursor movement key group 5B is a mutually independent double action key. The input pressure level of the ↑ key 17 is set to UL in the RAM 15, the input pressure level of the ↓ key 18 is set to DL, the input pressure level of the → key 19 is set to RL, and the input pressure level of the ← key 20 is set to LL. be done.

Next, the cursor movement control process of this embodiment will be explained with reference to flowchart 1 in FIG.

First, in step Sl, it is monitored whether there is any key input.

This is because when there is a key input from the keyboard 5, the above-mentioned interwoven signal is outputted from the keyboard controller 6 to the microprocessor l, and upon input of this interwoven signal, the process proceeds to step S2.

In step S2, the cursor discrimination table C in the RAM 15 is
DT is checked to see if there is any input from the cursor movement key group 5B. If the cursor movement key group 5B is not input, the process advances to step S3 and the process corresponding to the input key is executed.

When the cursor movement key 4I5B is being input, the process advances to step S4, and the KB data in the RAM 15 is set in the corresponding suppression level register. The extrusion level is "1" when the key is pressed lightly, and "1" when the key is pressed deeply.
2”. Then, in step S5, the KB in the RAM 15 is
Check to see if there are any other keys being entered. If there is no other key input, the counter of the corresponding suppression level register is set to "1", which is a low movement level, regardless of the input suppression level in step S6. Then, the processing from step S10 onwards is executed.

If there is another key input in step S5, step S
Proceeding to step 7, it is checked by CDT whether the other key is a cursor movement key other than the one detected in step S2 or An, and if there is no other cursor movement key, the process proceeds to step S6 described above.
If there is another cursor movement key input, step S8
Then, the data for this cursor movement key of KB is set in the corresponding suppression level register. Then, in step S9, it is checked whether the cursor can be moved by inputting these two cursor movement keys.

This is because in this embodiment, the cursor can be moved in 16 directions as shown at 21 in FIG.
It is represented by the combination specified in the movement discrimination table IDT in AM15.

As shown in Fig. 6, the cursor shown in Fig. 5 can be moved in combinations of upward and left or right directions, and in combinations of downwards and left or right. 21 is movable in 16 directions shown in the figure.

For example, a case will be explained in which the ↑ key 17 is pressed deeply and the → key 20 is pressed lightly.

UL is set to "2" and RL is set to "1". In this case, the combination shown in IDT in FIG. 6 becomes possible, and movement becomes possible in step S9, and step S1
Go to 0.

In step S10, the cursor position register is written in accordance with the value of the press level register. In the example above, the UL is “
2” and RL is “1”, the value of the row cursor register RCR is decreased by “2” and the value of the column address register C
"1" will be added to the value of CH.

Then, the process proceeds to step S11, and as a result of rewriting the contents of the cursor position registers (RCR, CCR) in step S10, whether scrolling is necessary, that is, if a new RCR,
Check whether the OCR count exceeds the limit value.

Specifically, RCT or margin register UMR, DM
If CCR exceeds R, the left margin register LMR,
This is to check whether it exceeds the RMR or not.

Here, if the value of the cursor register exceeds the value of the margin register, the difference between the value of the cursor register exceeding the value of the margin register and the value of the margin register is scrolled in the corresponding direction as the scroll amount, and in step S13, according to the scroll result, a new cursor position register is The value is set as the margin register value and the process proceeds to step S14.

If scrolling is not necessary in step S11, the process directly advances to step S14, and in step 314, the display controller 9 performs CR according to the new cursor position register value.
Move the cursor position on T8. and step S
Pressure level register (UL, DL, RL, LL) at 15
, and return to step Sl.

Further, in step S9, for example, when the ↑ key 17 and the ↓ key 18 are input, UL and DL are set, which is a combination not found in the IDT shown in FIG. 6, and the cursor cannot be moved. Process. Here, it is conceivable to alert the operator by outputting an alarm sound or the like. Then, the process proceeds to step S15, where the suppression level register is reset, and step S1
Return to

As mentioned above, the cursor displayed at 21a in FIG.
By making a shallow stroke of the key 20 and inputting an input, it can move as shown by the broken line and directly move to the position 21b.

By using keys and means that can detect the suppression level in this way, the direction of movement of the cursor can be determined by the sum of vectors in two directions.

Furthermore, in the above explanation, we have described an example in which a double action key is used as a key for moving the cursor, or by making it possible to detect fine suppression levels using a pressure-sensitive resistor r etc., the direction of movement can be further subdivided. Needless to say, it is also possible to set the moving direction linearly.

Furthermore, in the following explanation, a character display was used as an example, and the movement of the cursor was performed in units of character positions. However, by having a cursor position register in units of dots like in a graphic display, it is also easy to move the cursor in units of dots. can be done.

Although the above explanation shows an example of moving the cursor, any displayed graphic can be moved in exactly the same way. This means that the figure to be moved is t
This can be accomplished extremely easily by specifying the desired location and then inputting the movement instruction key.

[Effects] As explained above, according to the present invention, the displayed figure on the display means can be directly moved in any direction, and very efficient processing can be performed.
