Abstract

PURPOSE:To execute efficiently an input by an inexpensive constitution, by providing an auxiliary input device having 16 keys corresponding to a hexadecimal number, separately from a personal computor body. CONSTITUTION:A titled computer is provided with a CPU10 constituted of a control part, an operating part, etc., a PPI 11 for executing an input and an output of a data between said CPU and an input/output device, and a decoder 12 being a selecting circuit for generating an output signal from in a combination of input signals. A key scan signal is processed by the decoder 12 through the CPU10 and the PPI11, and inputted to one of key matrices of a keyboard 2. A code corresponding to each key is outputted from the other of said key matrices, inputted to the CPU10 through the PPI11 and processed. In this case, an auxiliary input device 4 is provided, and each key corresponding to said keyboard 2 is disposed as connected in parallel. In this way, by operating the key of the auxiliary input device 4, the same code as the key of the keyboard 2 is outputted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Technical Field of the Invention] The present invention relates to a personal computer equipped with an auxiliary input device having keys each corresponding to a hexadecimal number.

BACKGROUND ART FIG. 1 is a perspective view showing a conventional general personal computer.

In the figure, 1 is a main body of a personal computer, and 2 is a keyboard having a large number of keys corresponding to alphabets, kana characters, numbers, etc., respectively.

FIG. 2 is a diagram showing the keyboard 2 shown in FIG. 1 in detail. Each key is assigned a number as shown in the diagram, and the "5HIF'r" key and the "kana" key are assigned to each key. key on/
By turning off the switch and pressing a desired key, appropriate selection input can be made.

The conventional configuration described above requires a great deal of effort to become proficient in its operation, and this is one of the obstacles to its widespread use in households.

At present, the main use of personal computers in households is for game software. However, since this game software costs several thousand yen each, there was a limit to how much it could be purchased.

Therefore, programs found in magazines, etc. are entered from the keyboard 2, but this game software is usually written in a language consisting of combinations of hexadecimal numbers called 2 machine languages to increase response speed. You can enjoy the game by inputting a program written in this language.

However, this hexadecimal number has keys from 0" to 9" and 1l.
It uses a total of 16 keys from AI' to "F#", and on the Shear Keyboard 2, it is from On to +9.
The 10 keys up to # are in a relatively easy-to-read arrangement, but H
The six keys from "A" to "F" were arranged in an extremely difficult to decipher arrangement, making it difficult to input data on the C99 machine.

[Summary of the invention]

The present invention has been made in view of the above points.

An auxiliary input device having at least 16 keys each corresponding to a hexadecimal number is provided separately from the main body of the personal computer, and a transmission means is provided for transmitting key manual signals from the auxiliary input device to the main body of the personal computer. A burner computer with an auxiliary input device is provided.

[Embodiments of the invention]

FIG. 3 is a perspective view showing an embodiment of the present invention.

In the figure, 3 is a main body of a personal computer, and a keyboard 2 is provided thereon. 4 is an auxiliary input device, which has 16 keys on the top surface, each corresponding to a hexadecimal number from IIO# to II F m, ',' (comma) and "CR".
Two keys (carriage return) are arranged in order.

Reference numeral 5 denotes a cable serving as a transmission means for transmitting key manual signals from the auxiliary input device 4, and is composed of a plug 6 and a cord T. 8 is a socket provided in the main body 3, and by inserting the plug 6, the 2 main body 3 and the auxiliary input device 4 are connected.
and are electrically connected.

FIG. 4 is a circuit block diagram of the system shown in FIG. 3.

In the figure, numerals 2 and 4 have the same configurations as those described above, and numeral 10 denotes C, which is composed of a control section, an arithmetic section, a storage section, etc.
PU (central processing unit), 11 is a PPI (programmable peripheral interface) as an interface for inputting and outputting data between the CPU 10 and input/output devices, and 12 is one or more outputs from a combination of input signals. A decoder serves as a selection circuit that generates a signal, and the Shaky scan signal is processed by the decoder 12 via cPUIO and PPIII, and input to one of the key matrices of the keyboard 2.

The code corresponding to each key is output from the other key matrix and is input to cPUlo via PPl11 for processing. Each key of the auxiliary input device 4 is arranged so as to be connected in parallel to each corresponding key of the key matrix of the keyboard 2. Therefore, even if the key on the auxiliary input device 4 is turned on, the same code will be output to the CPU 10 even if the corresponding key on the keyboard 2 is turned on, so all nine machine language programs can be input from the auxiliary input device 4. Become. As a result, even a person who is not accustomed to operating the keyboard 2 can input data extremely efficiently by using the auxiliary input device 4 in which only keys corresponding to hexadecimal numbers are arranged in an orderly manner. Furthermore, in terms of cost, it is only necessary to add a unit mainly consisting of a key, resulting in an inexpensive configuration, and it can be said to be an extremely useful means, especially for home use.

Further, the auxiliary input device 4 is configured to be electrically connected to the main body 3 through the socket 8.

The auxiliary input device 4 can be removed when not in use, and furthermore, if the auxiliary/dynamic input device 4 is sold separately as an option, the basic price of the main body 3 of the personal computer can be reduced. be.

Practically speaking, in addition to the 16 keys each corresponding to a hexadecimal number as in the above embodiment, the "CR" key 11. Although it is effective to integrate the # keys into about 18 keys, the number is not limited to this, and it is sufficient that the keys include 16 keys, each corresponding to a hexadecimal number.

Furthermore, it goes without saying that the auxiliary input device 4 and the main body 3 may be connected by a wireless configuration using infrared rays or the like instead of a cable 5.

〔Effect of the invention〕

As explained above, according to the present invention, an auxiliary input device having at least 16 keys each corresponding to a hexadecimal number is provided separately from the main body of the personal computer, and key human input signals from this auxiliary input device are transmitted to the By providing a transmission means for transmitting data to the main body of a personal computer, an extremely convenient means for inputting machine language can be provided at low cost.
