Abstract: A load/unload control system for a tray, the load/unload control system includes a control module and a drive module. The control module is used for controlling a voltage, the control module includes a storage unit for storing instructions and an output unit constructed and arranged for reading the instructions from the storage unit and outputting the instructions. The drive module is coupled to the drive module for supplying the voltage adapted to move the tray based on the instructions, the instructions comprising at least one step-up voltage instruction for increasing the voltage during a load process and at least one step-down voltage instruction for decreasing the voltage during an unload process. A related control method for controlling a voltage to load/unload a tray is also provided.

Abstract: A drawer device or container holder includes a member disposed in a closed position to be able to draw into an open position, a driving device attached to the member to move the member between the closed position and the open position, and a sensing device for sensing whether or not the member is drawn out for a predetermined amount from the closed position. A control device controls the driving device to cause the member to be housed when the sensing device senses that the member is not drawn out for a predetermined amount. Also, a container placed on a tray can be sensed assuredly regardless of vibration during a movement of a vehicle.

Abstract: A recording apparatus effects recording on a recording material by a recorder. The apparatus includes a tray, mountable to the recording apparatus, for stacking a recording material, a portion to be detected, provided on the tray to permit detection of a position of the tray, and a tray position detecting portion for detecting the portion to be detected. A position of the recording material stacked on the tray is detected by detecting the position of the portion to be detected.

Abstract: A tray (1) having blocking portion for an optical disc driver can be received in a housing (2). The tray includes a main body (11) and a blocking portion (12). The main body includes a rear end (114) received in the optical disc driver and a front end (113). The front end can move out of the optical disc driver. A recess (115) is defined in the main body, for accommodating an optical disc therein. The blocking portion has a protrusion (123), a free end (121), and a connecting end (122). The tray is prevented from sliding completely out of the optical disc driver by the blocking portion. When the tray is manually pulled, the blocking portion is bent inwardly, and the tray is completely detachable from the optical disc driver. The blocking portion helps prevent the tray from being damaged or broken.

Abstract: A control method for ejecting optical disk from optical disk driver is proposed and applicable to both vertical type and horizontal type optical disk drivers. The control method firstly measures the minimal voltage require by the tray motor to eject a tray with or without an optical disk loaded thereon. Afterward, the disk loading condition of the tray is examined before the ejecting voltage is applied to the tray motor. The minimal voltage determined in above is applied to the tray motor according to the disk loading condition of the tray.

Abstract: The present invention relates to a disc ejecting apparatus for quickly ejecting a disc by utilizing a pick-up drive motor. A slip mechanism is provided in a first route leading from the pick-up drive motor to a pick-up, and a switching mechanism is provided in a second route leading from the pick-up motor to a disc ejecting mechanism.
