摘要： A loading mechanism (11) has first and second arm members (30, 30) rotated about first and second supporting points (31, 31), a cam mechanism (60) for rotating, by driving force from a drive source (71), at least either of the first and second arm members (30, 30) to hold and feed a disc (12), and a third arm member (80) independently rotated about a third supporting point (81), applying urging force to the disc (12) by an urging means (86) to hold the outer circumferential edge of the disc (12). In the holding and feeding of the disc, the center part of the disc (12) is present inside a figure obtained by connecting adjacent points out of three or more points of contact between the disc (12) and the first to third arm members (30, 30, 80).

摘要： A disc cramp device which holds a disc by sandwiching it by a turn table and a cramper, according to the present invention, includes a cramper arm which is rotated in a direction to move close to the turn table and a direction to move away from it, a plate spring member, a part of which is fixed to the cramper arm, which lifts the cramper during an uncramping time, and which presses an upper center of the cramper in a direction of the turn table during a cramping time. It is constructed so that by providing tongue pieces for pressing the upper center of the cramper at a tip end portion of the cramper arm, the plate spring member presses the cramper while it is held at both sides during the uncramping time, and the plate spring member is pressed by the fixing member to be elastically deformed during the uncramping time. Consequently, according to the disc cramp device of the present invention, the number of components is reduced, and the height of the space for transferring the disc can be made large with respect to the height of the entire device, in addition to which, the driving force in a cramping and uncramping operations can be made small.
