Abstract: A projection electronic apparatus is presented. A movable keyboard component is disposed on a host of the electronic apparatus, and a projection component is disposed on the host. When the keyboard component is moved out from the host, a projection ray from the projection component is projected on a screen board outside the host, so as to display a projected screen picture. In addition, the screen board may also be pivoted to the host. When the screen board is opened from the host, the keyboard component is moved out from the host, and the projection ray from the projection component is projected on the screen board, so as to display a screen picture having a maximum scope.

Abstract: A resonance removing mechanism for a CD-RW drive is provided. The mechanism includes a first holding-down plate on which a read/write head is installed through two sliding rods. The first holding-down plate connects to a chassis frame through a series of first elastic pads, and a second holding-down plate is connected in parallel to the first holding-down plate through a series of second elastic pads. Active components are installed on the first holding-down plate and the second holding-down plate.

Abstract: A resonance removing mechanism installed on CD-RW drive to remove resonance. The CD-RW drive contains a tray, a read/write head, a CD-RW driving plate and other components. All these components are installed on a chassis frame. The tray is controlled by the motor at the front of the chassis frame through a set of gears and a linking component so that it can expand and contract on the chassis frame. The read/write head is installed on the first holding-down plate together with the CD-RW driving plate through two sliding rods. The first holding-down plate connects to the chassis frame through a serial of the first elastic pads, while a serial of the second elastic pads is installed and connects to the second holding-down plate parallel to the first holding-down plate to form a resonance removing mechanism.
