<p>A lever-type detector, a stylus, and an automatic stylus exchanger allow styluses of different types to be exchanged automatically and reduce the burden of exchanging the styluses of different types for the lever-type detector. An approximately U-shaped notch is formed in a seating plate provided for a stylus body. In order to attach a stylus to a stylus holder, the longitudinal direction of the stylus body is set in a direction orthogonal to the central axis of a shaft body of the stylus holder, and the seating plate is moved in the direction orthogonal to the central axis of the shaft body. Then, the notch guides the shaft body to the center of gravity of the whole stylus on the seating plate. With the shaft body guided to the center of gravity by the notch, a flat swinging member holds the seating plate detachably.</p> |
