Abstract: A switching mechanism for a toner cartridge includes a base and a sliding member. The base is mounted to a housing. A chamber is defined between the housing and the base for receiving the sliding member. The base has a guiding slot. The sliding member has a body received in the chamber, a suspension arm extending from the body, a hook disposed on the suspension arm, and a post extending from the suspension arm and received in the guiding slot. When the sliding member is moved to different positions, an outlet of the toner cartridge can be closed or opened. The post moves along the guiding slot to cause an elastic deformation of the suspension arm for changing the position of the hook such that an erroneous operation of the switching mechanism can be avoided, and a mold for the switching mechanism is easy to manufacture to reduce the manufacturing costs.

Abstract: A protection method for manual ejection operation of optical disk drive is proposed. In the present method, a locked state is set when the optical disk drive is in normal rotation. The load-sensing switch would turn to the on position (stage) when the optical disk is loaded in the tray and in the rotating state. When a manual ejection operation with manual ejection function is activated, the load sensing switch would turn to the off position (stage). A controller senses the stage change from on position to off position. Then, the controller applies a voltage to the tray motor and the position of the load-sensing switch is returned to the on position. Therefore, a locked state is maintained.

Abstract: A method for editing a video data stream is suited for converting an analog AV signal into a MPEG file in a recordable player. The method includes the steps of: converting the analog AV signal into a plurality of continuous digital frames; inserting time information onto the digital frames; and encoding the digital frames with the time information into the MPEG file and recording the MPEG file onto an optical disc. In this way, when the recorded disc is played by different optical disk players, the time information is always shown on a screen at the same position.

Abstract: A recordable player has an external storage device to advantageously extend the capacity, facilitate the portability and provide the aseismatic design. The external storage device is additionally connected to a DVD or VCD recordable player. A USB transmission port or an IEEE 1394 transmission port is embedded in the DVD or VCD recordable player. Thus, data transmission between the player and the external storage device may be made through a USB transmission line or an IEEE 1394 transmission line. Therefore, AV data can be transferred to the external storage device from the DVD or VCD recordable player such that the AV data can be edited, rewritten and deleted. In addition, the data in the external storage device also can be transferred back to the DVD recordable player so that the data can be recorded and played.
