Claims

[Claims for Utility Model Registration] (1) In a keyboard device equipped with a non-locking shift key that maintains a shifted state while the key is being pressed and releases the shifted state when the key is pressed, the shift key is pressed. 1. A keyboard device comprising a mode switching key for switching between a mode in which the shift state of the data key is valid only for the first data key pressed after the data key is pressed, and a mode in which the shift key is original. (2) In a keyboard device equipped with a non-locking shift key, which maintains the shift state while the key is being pressed and releases the shift state when the keystroke ends, the key is pressed first after the shift key is pressed. A mode switching key for switching between a first mode in which the shift state is valid only for the data key and a second mode that is the original mode of the shift key, and a state in which the first mode is set by pressing the mode switching key. shift state holding means for holding the shift state when the shift key is pressed;
A keyboard device comprising: means for releasing the shift state held by the shift state holding means when the data key is pressed. (3) On a keyboard device used for inputting Roman characters, “a”,
Keys corresponding to the characters “i”, “u”, “e”, “o”, “tsu”, “ya”, “yu”, “yo” and “n” and keys corresponding to English letters A keyboard device is provided independently, and the above characters and English characters are directly input in a Roman character input mode.
