PURPOSE:To latch a disc to the standby position very simply and to prevent damae due to incomplete loading, by energizing one of disc guides supporting the disc from left and right sides with a spring, and providing a latching projection to give an insertion resistance. CONSTITUTION:The disc guides 33, 34 supporting the disc 2 from left and right sides are provided, one guide 33 is fixed to an inner cover, the other guide 34 is supported pivotally to a shaft 34a and energized to the guide 33 side with a spring 36. The inside of the guide 34 is provided with a latch projection 34b. In loading the disc 2, it is latched once to the projection 34b. The operator notices the position easily since the insertion resistance is increased at the standby position. Further, the disc is pushed in to be latched to a disc guide 37. Thus, damages to the disc due to incomplete loading are prevented. |
