Description

[Detailed description of the invention]

The present invention relates to improvements in keyboards, and more particularly to improvements in typewriters and information input keyboards that allow characters of multiple languages or writing systems to be typed or input from the keyboard. The above-mentioned keyboard was already developed in a patent application filed in 1974.
This was clarified by No. 085981. However, with the proposed keyboard, characters could only be entered by pressing the selection key or locking the key. for example,
When inputting Japanese, hiragana and katakana frequently appear alternately. Therefore, the typist is always aware of the selection key when pressing it, locking it, or unlocking it. For this reason, not only the efficiency of inputting operations may be reduced, but also input errors are likely to occur. The present invention has been made to improve the above-mentioned drawbacks, and an object of the present invention is to provide a keyboard that allows easy input by selecting two frequently used language systems or character systems and mixing them. Next, embodiments will be described in detail with reference to the drawings.
FIG. 1 is a block diagram of one embodiment of the present invention.
Reference numeral 10 is a group of selection switches. 20 is a three-state switching circuit. The selection switch group 10 is 10
It consists of three switches a, 10b, and 10c, one end of which is grounded and the other end connected to a three-state switching circuit 20. For example, switch 1
0a is for English letters, switch 10b is for hiragana,
The switch 10c is for selecting Kataka. Further, the switch group 10 is arranged so that it can be pressed with a finger along with other keys (not shown). The three-state switching circuit 20 outputs a signal corresponding to the switch pressed in the switch group 10. 3
0 is a selection means. This selection means 30 has the function of selecting any two language systems or writing systems from the aforementioned English characters, hiragana, and katakana language systems or writing systems. In this example,
Rotary switch 3 interlocks as shown in the figure.
1,32 is used. This rotary switch 3
1 and 32, conductive wires 41, 42, and 43 extend from the three-state switching circuit 20 so that English characters, hiragana, and katakana can be selected, respectively. Furthermore, the respective contacts 1, 2, 3 of the rotary switches 31, 32,
......, 6 are connected to one of the conductive wires 41, 42, and 43. Therefore, by rotating the not-illustrated knobs of the rotary switches 31 and 32, one of the six language systems or writing systems shown in the table can be selected depending on the combination of contact points.

[Table] In the figure, 1 in the table is selected.
50 is a changeover pedal switch. This pedal switch 50 has selected contacts 51, 52, 53 and a selection contact 54. Among these, the selected contact 51 is not connected to the others.
The selected contact 52 is connected to the rotary switch 31, and the selected contact 53 is connected to the rotary switch 32. The selection contact 54 is movable up and down, one end is grounded, and the other end connects the selected contacts 51, 52,
53 can be connected. Therefore, the selector pedal switch 50 can select two selected language systems or character systems by depressing the switch into upper and lower stages. The mechanical structure of the changeover pedal switch 50 is shown in FIG. That is, a selection contact 54 is formed on the pedal 55, and selected contacts 52 and 53 are arranged below it. 56
is a base plate and is rotatably connected to the pedal 55 at a fulcrum 57. Further, a spring 58 is provided near the center of the pedal 55 from the fulcrum 57, and the base plate 5
6 supports the pedal 55. As a result, even if the pedal 55 is depressed,
When the foot is released, the foot returns to its original position, and the selected contact 51 and the selection contact 54 are in contact with each other. Next, using an embodiment of the present invention, a case will be described in which Japanese characters are inputted. The typist first selects contact 1 of the selection means 30. As a result, when the pedal 55 is depressed to the lowest position with the foot, katakana can be selected, and when the foot is released from the pedal, the contact 54 is connected to the contact 52 and then settles on the contact 51, so that hiragana can be selected. Therefore, when typing hiragana,
It is sufficient to input the foot without pressing the pedal 55. When you should type katakana, use pedal 55.
Just step down and press the key to input. In this way, Japanese characters can be entered while operating the pedal 55 with the foot without relying on the language character series selection switch on the keyboard. Furthermore, if English letters are sometimes mixed in, it is sufficient to press the switch 10a on the keyboard and press the key corresponding to the desired English letter without operating the selection means 30. Furthermore, if the user wishes to return to hiragana again after inputting English characters, it is possible to press switch 10b in language selection switch group 10 on the keyboard. Hiragana can also be selected by depressing the pedal 55 until the contact 54 contacts the contact 52 and then releasing the foot from the pedal 55. In this way, by using the keyboard of the present invention,
Since two frequently used language systems or character systems can be selected by foot operation, input operations can be performed without having to be conscious of the language selection keys. This reduces input errors and improves work efficiency. Furthermore, by switching the selection means, any combination of language systems or character systems can be selected, and the selection keys on the keyboard can also be used together without any problems, making it extremely convenient. Furthermore, when selecting a language system or character system that is used frequently on one side and a language system that is used less frequently on the other hand, by assigning the language system or character system that is used less frequently to the selected contact point 53, it is possible to select a language system or a character system that is used less frequently. , the one that is used less frequently is selected, and by touching the selected contact 52 on the way back to the pedal, the language system or character system that is used more frequently is normally selected, making it possible to input characters with extremely good operability. be. In other words, the return to the original system can be made extremely smoothly.
