Abstract
A clamp operating member which is bendable cooperates with a spindle to support a clamping member which cooperates to clamp a disc-shaped recording medium and to position the clamping member in a clamped position and an unclamped position. The arrangement has a restraining member engaging with the clamp operating member to bend the clamp operating member when the clamp operating member is in a position to position the clamping member in an unclamped position. The clamp operating member is bent by the restraining member when in the unclamped condition to reduce an operating space occupied by the clamp operating member.
