Abstract

PURPOSE:To facilitate the slanting movement of a cursor by providing a key switch at the middle position of each side of a single square key top and depressing a corner part of the key top. CONSTITUTION:Key switches (a)-(d) are provided at middle positions of respective sides of the single square key top. When a point A is pressed down, only the key switch (a) corresponding to ''longitudinal arrow'' is turned on and the cursor moves up; when a point B is pressed down, the key switches (a) and (b) corresponding to ''longitudinal array'' and '' '' are turned on and the cursor moves up and right. Similarly, the cursor moves right when a position C is pressed down and right when a position D is pressed down when a position E is pressed down and left when a position F is pressed left when a position G is pressed up and left when a position H is pressed, respectively. When the center position (i) of the keytop is depressed, none of keys turns on. Consequently, the movement by the cursor key matching with a human sense is realized.

Description

[Detailed Description of the Invention] (a) Technical field of the invention The present invention relates to a keyboard device ff? (Regarding this, I have added a gi keyboard equipped with keys for controlling cursor movement.
jj.

(b) Prior Art and Features Figure 1 shows an example of a conventional keyboard device. In the figure, 1 is each H key arrangement section, and 2 to 5 are cursor keys. In conventional keyboard devices, each of the control keys ``move right'', ``move left'', ``move up'', and ``move down'' is independent, so that the It is a duplicate work, and the movement is Digimel-like (for example, when moving to the upper right, press the right movement key, then perform the upward movement key operation,
It had the disadvantage of being a man-machine device that was similar to that of an ordinary person.

(c) Object of the Invention The object of the present invention is to provide a cursor movement display that is required to be inserted into the cursor movement operation during keyboard operation in a data processing system, without increasing the number of key switches or hardware. An object of the present invention is to provide a keyboard device which provides an improved system of constraints and improves the OJ functionality of a man-machine interface.

B) Structure of the Invention According to the present invention, the above-mentioned object is achieved by creating a single key top whose top surface is a rectangle, and a midpoint between each side of the rectangular key dog. A key switch is provided on the base at the position where the key is to be placed, and a key top guide J is distributed by warping a gap between the key top and the key top on the outer periphery of the key dot horn.
By suppressing the vicinity of the midpoint of each side of the rectangular operation surface, only the corresponding single key switch operates, and pressing the vicinity of the corner of the operation surface. A cursor movement control key configured so that two key switches corresponding to the two sides forming the corner are operated, and neither key switch is operated when the vicinity of the center of the operation surface is pressed. This is achieved by a keyboard device equipped with

(E) Embodiment of the Invention FIG. 2 is an external view of a keyboard device according to an embodiment of the present invention. The cursor H36 control with a single key top is the best. FIG. 3 is a detailed view of the cursor movement control key shown in FIG. In the third session, 11 is the key top, 12 is the base,
13 is a key top guiding fixing member, 14 is a key switch, 15 is a key switch pressing projection, 16 is a locking projection, and 17 is a spring member. There are 15 protrusions for suppressing the switch, which are provided on the lower surface of the center point of each side of the square key dog 11 shown in the plan view of FIG. 3(b). is located on the lower surface of the center point of the key top 11. Further, the usage rule 9 of the retaining protrusion 16 and the base body 12 is that the key switch suppressing protrusion 15
This is set smaller than the I\J1 gap of the key switch 14.

At the ij and 5 formations in Figure 3, the center A of the key dog 11
When pressed, the locking projections 16 come into contact with the base 12 before each key switch pressing projection 15 reaches the key switch 14, and the locking projections 16 are locked, so that none of the keyswitches operates.

↓ Next, when the midpoint of any side of the key top 11 is pressed, the key dog 11 is tilted, and the key switch suppression protrusion 15 at the pressed location is lowered to operate the corresponding key switch. . Furthermore, when any corner of the key dog 11 is pressed down, the two sides that make up the corner tilt downward, and the key switch suppressing protrusion 15 attached to the two sides descends together. , operate the two corresponding key switches. In this state (on an N-key rollover keyboard, it is possible to detect that N keys are turned on at 4 o'clock), if the codes corresponding to each key switch are alternately repeated and output to the information processing device, the information On a processing system display, the cursor appears to move diagonally across the screen. Furthermore, if you operate the cursor in conjunction with the shift key, you can vary the number of self-repeat operations, allowing smooth cursor movement.

Below, specific operational aspects according to the present invention will be explained. FIG. 4 is a diagram showing the relationship between key tops, key switch positions, and pressed positions. In FIG. The operation is as follows.

When the 0 point is pressed and the A point is pressed, only the "↑" key (■) is turned on and the cursor moves upward.

0 point is pressed When the B point is pressed, the "↑" and "→" keys (■, ■) are turned on and the cursor moves to the upper right.

0 point is pressed When the C point is pressed, only the "→" key (■) is turned on and the p cursor moves to the right.

When the 0 point is pressed, the "→" and "↓" keys (■, ■) are turned on and the deer crane moves to the lower right.

[F] point pressed When E point is pressed, the "↓" key (■ only turns ON) and the crane moves downward.

[F] point pressed When the F point is pressed, the "↓" and [←J keys (■, ■) are turned on and the υ cursor moves to the lower left.

When the 0 point is pressed and the G point is pressed, only the "←" key (■) is turned on and the deer crane moves to the left.

When 0 point is pressed 1 ■ When the point is pressed, "←" and "↑" keys (■, ■) are ON.
The cursor will move to the upper left.

Press the 0 point When you press the i point, it gets stuck in the middle, and all switches are OFF.
Not N.

Further, in the above case, a zero-order control system will be described in which the self-reply (M) period can be doubled to shorten the time required for movement by simultaneously operating the shift keys. FIG. 5 shows the relationship between keys and outputs in the case of normal self-repeat. FIG. 6 shows a case in which double-speed self-repeat mode is activated by detecting that the shift key is pressed at the same time as the shift key. When two cursor keys are turned on, codes corresponding to each are repeated as a set. This is called the cursor repeat function and is shown in FIG.

(F) Effects of the Invention According to the present invention, since the cursor can be easily moved diagonally, it is possible to perform smooth processing in accordance with human senses when moving the cursor, which alleviates the inconvenience of getting used to the keyboard and makes it more user-friendly. It can bring about the excellent effect of making it easier.
