TECHNICAL FIELD The present invention relates to a keyboard, and more particularly, to a keyboard that can be applied to game play to prevent ghost keys conditions from occurring.

U.S. Patent No. 4,888,600, "KEYBOARD ARRANGEMENT WITH GHOST KEY CONDITION DETECTION," proposes the detection of ghost key status and its circuitry to solve the problems caused by ghost keys of the keyboard. It was. However, there is a problem that the manufacturing cost is increased by adding the detection circuit.

Conventional keyboard configurations used on IBM PCs or IBM compatible computers have been used to control orientation during game play, while conventional keyboard configurations utilize ↑ -keys, to control orientation and detect ghost keys. Only one key set had to be provided, such as the ↓ -key, ← -key and → -key. Thus, other key sets that control direction, such as the W-key, A-key, S-key, and D-key, could not prevent the ghost key state from occurring. Therefore, there was an uncomfortable problem for the PC game player.

In order to overcome the problems of the prior art, the inventors of the present invention provide a keyboard configuration for a plurality of sets of direction control keys that can overcome the problems of the prior art, and a method and a keyboard configuration for preventing the generation of ghost keys. Provide a method.

It is a first object of the present invention to provide a keyboard on which a plurality of key sets can control a direction while preventing the generation of ghost keys for PC game players who simultaneously input any key set or other keys.

In order to achieve the above object, the keyboard according to the present invention includes a plurality of key matrices and a plurality of key sets, wherein the plurality of key sets include ↑ -letter key, ↓ -letter key, ← -letter key and →- A first set of keys disposed in a key matrix comprising a character key; A second set of keys disposed within a key matrix including W-letter keys, A-letter keys, S-letter keys, and D-letter keys; A third set of keys disposed within a key matrix including I-letter keys, J-letter keys, K-letter keys, and L-letter keys; A fourth set of keys disposed within a key matrix including 4-character keys, 5-character keys, 6-character keys, and 8-character keys; And a fifth set of keys disposed in a key matrix comprising a two-character key, a four-character key, a six-character key, and an eight-character key, each scan line belonging to any character key in any key set. And each return line is different from the remaining scan lines and return lines belonging to the remaining related characters in the same set.

The above and other objects and advantages of the present invention will become more apparent from the following detailed description and the accompanying drawings.

1 is a schematic diagram showing a circuit structure of a keyboard according to the present invention.

As shown in FIG. 1, the keyboard 10 uses the I / O port of the controller 100 as scan lines 1001 and return lines 1003. The scan lines 1001 and return lines 1003 constitute a key matrix 101. In the keyboard 10, a plurality of characters from the first key set to the fifth key set are arranged in the key matrix 101 to prevent ghost keys. The amount of the key matrix 101 arranged for the keyboard 10 according to the actual generation amount of the total key numbers may be at least one, and each key matrix 101 is independent. 2 and 3 are schematic diagrams showing another circuit structure of the keyboard according to the present invention. The keyboard 10 may be used in an IBM PC or an IBM compatible computer, such as a 83-key keyboard, a 101-key keyboard, a 104-key keyboard, and the like.

The first to fifth set of keys are defined as follows. The first set of keys includes ↑ -character keys, ↓ -letter keys, ← -letter keys and → -letter keys, and the second set of keys includes W-letter keys, A-letter keys, and S-letters. Key and D-letter key. The third set of keys includes I-letter keys, J-letter keys, K-letter keys, and L-letter keys, and the fourth set of keys includes 4-letter keys, 5-letter keys, 6-letter keys, and 8- letter keys. And a fifth key set includes a two-character key, a four-character key, a six-character key, and an eight-character key. 4-character keys, 6-character keys, and 8-character keys are defined simultaneously in both the fourth and fifth key sets, and the two-character and five-character keys are numeric areas of the keyboard 10. Are placed jointly in.

Generally, characters belonging to the first to fifth key sets are used to control the direction in various kinds of game software. One or more keys may be activated in the key set while playing the game, and most of the conventional keyboards generate ghost key conditions when more keys are pressed. On the other hand, if any key set of the first to fifth key sets of the keyboard 10 is operated, this state can be prevented from occurring.

A first preferred embodiment of the keyboard 10 according to the invention shown in FIGS. 2 and 3 is presented below. 4 is a layout view showing a plurality of characters of the first embodiment of the keyboard according to the present invention.

The keyboard 10 includes a key matrix 101a, a key matrix 101b, and first to fifth key sets. Key matrix 101a consists of eight scan lines and 17 return lines, and key matrix 101b consists of one scan line and three return lines. Key matrix 101a is independent of key matrix 101b. The key matrix 101a is composed of the first key set, the second key set, the fifth key set, the I-letter key and the K-letter key of the third key set, and the four-letter key, the six-letter key, and the fourth key set. Contains an 8-character key. Key matrix 101b includes the J-letter keys and L-letter keys of the third key set, and the 5-letter keys of the fourth key set. Multiple scan lines and multiple return lines belonging to any character key of multiple key sets of key matrix 101a are different from the remaining scan lines and return lines belonging to the remaining relative characters of the same key set. It should be noted that. For example, scan lines and return lines belonging to the ↑ -character key are scan lines and return lines belonging to the other three characters of the first key set, ↓ -letter key, ← -letter key and → -letter key. Is different.

Further, all scan lines and return lines of characters in key matrix 101a intersect another key matrix defined by a key intersecting matrix (103), which is indicated by the diagonal lines in FIG. . There is no key in the key crossing matrix 103 in the keyboard 10. The remaining keys 105 are disposed in the area except for the key crossing matrix 103. Therefore, the present invention can prevent the ghost key state even when only one remaining key 105 is activated while any one of the first to fifth key sets is in operation.

A second preferred embodiment of the keyboard 10 according to the invention shown in FIG. 1 is presented below. 5 is a layout diagram illustrating a plurality of characters of a second embodiment of a keyboard according to the present invention.

The keyboard 10 of the second embodiment can reduce the total amount of keys in consideration of unnecessary keys. Thus, all the keys of the keyboard 10 can be placed in one key matrix 101. In FIG. 5, the key matrix 101 is composed of eight scan lines and seventeen return lines. Within the key matrix 101 is a second key set, a third key set, a fourth key set, and a fifth key set. The plurality of scan lines and the plurality of return lines belonging to any character key of the plurality of key sets of the key matrix 101 are different from the remaining scan lines and the lantern lines belonging to the remaining related characters in the same key set. For example, the plurality of scan lines and the plurality of return lines belonging to the W-character key of the second key set are the remaining three characters in the second key set, A-letter key, S-letter key and D-letter key. It is different from scan lines and return lines belonging to.

In FIG. 5, the other keys 105 are disposed in an area excluding the key crossing matrix 103. In FIG. 5 the key crossing matrix 103 is indicated by an oblique line. Therefore, even if only one remaining key 105 is activated while any one of the first to fifth key sets is in operation, the present invention can prevent the ghost key state.

The ↑ -letter key and the ↓ -letter key allow the same scan lines and return lines to be used jointly because the probability that the ↑ -letter key and ↓ -letter key of the first key set are activated at the same time is very low. Logically, the ← -letter key and → -letter key allow the same scan lines and return lines to be used jointly because the ← -letter key and → -letter key of the first key set are very rarely activated simultaneously.

The keyboard according to the present invention provides a plurality of key sets for controlling direction in a computer game, as the characters belong to the first to fifth key sets. In addition, even if a plurality of keys are activated at the same time when operating a character of an arbitrary key set and other keys while playing a game, the keyboard configuration according to the present invention can avoid the ghost key state.

While preferred embodiments of the present invention have been described using specific terms, such descriptions are for illustrative purposes only and it is understood that various changes and modifications may be made therein without departing from the spirit and scope of the following claims. You must lose.
