Slot-in optical disk drive with transmission belt

A slot-in optical disk drive with a transmission belt comprising:

• a base chassis with at least one first sliding slot and one second sliding slot on two sides thereof;
• a first sliding board with a driving pulley on one end thereof mounted on the first sliding slot;
• a first rail member with a first guide slot thereof disposed on the first sliding board;
• a transmission belt put on the first guide slot and the driving pulley;
• a second sliding board inserted in the second sliding slot;
• a second rail member with a second guide slot thereof installed on the second sliding board;
• a first synchronous gear disposed on top of the base chassis;
• a second synchronous gear arranged on top of the base chassis and engaged with the first synchronous gear;
• a first synchronous link with two ends thereof connected to the first sliding board and the first synchronous gear respectively;
• a second synchronous link with two ends thereof connected to the second sliding board and the second synchronous gear respectively;
• a driving mechanism disposed on the base chassis for rotating the driving pulley to drive the transmission belt;
• wherein when an optical disk is loaded on the disk drive, the optical disk enters the first guide slot and the second guide slot and pushes the first sliding board and the second sliding board to move toward the two sides of the base chassis synchronously while the driving mechanism drives the transmission belt to move the optical disk into the disk drive for retrieving data.
