PURPOSE:To set a record on a player without touching the record directly, by forming a groove which has width nearly equal to the diamter of a record center hole from a center part to the center part of an opening side. CONSTITUTION:A jacket 1 has the groove 1b which extends to a position where the center hole 2a of the record 2 is confirmed externally, i.e. from the opening part 1a of the jacket 1 to the center hole 2a of the record 2 and has the width equal to or a little bit greater than the diameter of the center hole 2a. While the jacket 1 contains the record 2, the center hole 2a of the record 2 is fitted around the turntable shaft 3a of the player 3 and the jacket 1 is drawn as shown by an arrow A to set the record without touching. When the record 2 is stored in the jacket 1, the jacket 1 is handles in the opposite direction. |
