  • Disc player apparatus with upper and lower rollers for transporting and guiding a disc
    Patent number: 7814504
    Abstract: There is provided a disc player apparatus capable of transporting a disc (11) by holding the disc (11) between a lower roller (70) and an upper roller (80). The lower roller (70) and the upper roller (80) are rockably supported with respect to a main body (20a). A flat spring (210) which urges the upper roller (80) is attached to an upper case (200a) that is attached to the main body (20a). The urge of the flat spring (210) is applied via a roller support member (810) which supports the upper roller (80). The pressure is applied evenly to the upper roller (80), enabling to reduce diagonal travel of the disc for example, and to transport the disc smoothly.
