Cd holder

Abstract

A CD holder to hold multiple compact disks basically consists of a first housing ( 10 ) and a second housing ( 20 ) pivotally connected to the first housing ( 10 ). The second housing has multiple slots ( 25 ) to arrange the CDs inside and a selecting device ( 30 ) secured between the first housing ( 10 ) and the second housing ( 20 ) to pick up a selected CD. The selecting device ( 30 ) is comprised of a shaft ( 31 ) and a roller ( 34 ) mounted around the shaft ( 31 ), wherein the roller ( 34 ) has multiple resilient blocks ( 36 ) mounted on the periphery to contact the corresponding CD. The first housing ( 10 ) is able to clamp the selected CD when the roller ( 34 ) rotates to the corresponding position.
