PROBLEM TO BE SOLVED: To prevent a collision sound between a tray and a hook when the tray is pulled into a case and when it is pushed out of the case. SOLUTION: A projection part 4 for pressing a hook 25A to the side face of a tray T when the pulling-in force or the pushing-out force of an elastic holding member 15 is applied to the tray T is disposed in a chassis for supporting the hook 25A so as to freely move. A projected part 25d is formed in the hook 25A to be confronted and abutted on the projection part 4 when the tray T reaches the position of applying the pulling-in force or the pushing-out force.
