Claims

[Scope of Claim for Utility Model Registration] (1) A keyboard chassis, a key swingably supported by the keyboard chassis, and an electrically conductive long piece provided on the key side that moves as the key swings. a movable slider having a shape, a fixed contact provided on the keyboard chassis side at a position where the movable slider can come into contact with the movable slider as it moves; key pressing speed detection means for detecting the time from the time when one end of the child makes electrical contact to the time when the other end makes contact, and detects the key pressing speed of the key based on the detected time; A key press detection device characterized by: (2) a keyboard chassis; a key swingably supported by the keyboard chassis; a conductive movable slider that is provided on the key side and moves in accordance with the swinging of the slider; and the keyboard chassis side. an elongated fixed contact disposed at a position where the movable slider can come into contact with the movable slider as it moves; and the movable slider electrically contacts one end of the fixed contactor. key pressing speed detection means for detecting the time from the time when the key is touched to the time when the key touches the other end, and detecting the key pressing speed of the key based on the time; Device. (3) a keyboard chassis; a key swingably supported by the keyboard chassis; a conductive movable slider that is provided on the key side and moves as the key swings; and the keyboard chassis side. a plurality of fixed contacts disposed at predetermined intervals at positions where the movable slider can come into contact with the movable slider as it moves; A key press detection device comprising: a key press speed detecting means for detecting the time when movers are sequentially electrically contacted, and detecting the key press speed of the key based on the detected time. (4) a keyboard chassis; a key swingably supported by the keyboard chassis; and a plurality of conductive elements provided at predetermined intervals on the key side and that move as the keys swing. a movable slider; a fixed contact provided on the keyboard chassis side at a position where the movable slider can come into contact as it moves; and a pair of movable contacts adjacent to the fixed contact. A key press detection device comprising: a key press speed detecting means for detecting the time when the slider makes electrical contact in sequence, and detecting the key press speed of the key based on the detected time. .
