Patent ID: 7065773

Claim:
A disc loading-and-unloading structure for a disc apparatus comprising: a drive motor; a drive roll assembly comprising first and second drive rolls and, an intervening transmission gear wheel, and a rotatable arm plate, the first drive roll being rotatably fixed to a stationary stud axle standing upright on a chassis of the disc apparatus, next to one end of a disc slot made in the front of the apparatus, and the first drive roll being connected to the drive motor; the first and second drive rolls being fixed to the opposite ends of the rotatable arm plate with the intervening transmission gear wheel sandwiched therebetween; a free-roll slider movably fixed to the chassis of the apparatus, next to the other end of the disc slot, the free-roll slider comprising first and second free rolls, and a slidable arm plate, the first and second free rolls being fixed to the opposite ends of the slidable arm plate; a rotary lever rotatably fixed to the chassis on the rear side of the chassis so that its free end may abut a disc when being inserted from the disc slot and advancing toward the rear side in the apparatus; a slider operatively connected to the rotary lever; and link-and-spring connection means for normally urging the free-roll slider toward the drive roll assembly, allowing the free-roll slider to move apart from the drive roll assembly as a counter action to hitting-and-pushing by the disc when inserted into the apparatus; wherein the drive roll assembly, the free-roll slider and the rotary lever are adapted to work together and hold the disc on its circumference by applying the second drive roll, the second free roll and the free end of the rotary lever to three points on the circumference of the disc.
