出装置。The sensor device includes a shielding plate that is attached to the tone arm and operates in unison with the tone arm, and a light-emitting element and a light-receiving element arranged between the shielding plate, and detects the tracking error of the tone arm by detecting the movement of the shielding plate. A tracking error detection device configured to detect changes in the amount of light incident on a light-receiving element by using a mask, in which a slit in the shape of an exponential curve is formed between the light-receiving element and the light-emitting element of the sensor device. A tracking error detection device for a tone arm, characterized in that a plate is provided.
