2. Related Art
In recent years, it is common to record information, such as sound, image or personal data, on optical discs. Since optical discs have large storage spaces and are easy to be carried and preserved, people may rapidly exchange information by using optical discs, and gain lots of fun by doing so.
The optical drive, as a reading device for an optical disc, is therefore becoming one of the essential peripheral equipments of computer. In general, as shown in
As users value much more on the appearance of computer mainframes, the design with integrity by covering the optical drive 1 with the computer housing 111 has been revealed these days. A button 14′, however, has to be disposed on the computer housing 11 at a position corresponding to that of the button 14 covered therein, and through the function of a linking rod 15, the button 14 on the optical drive 1 is being pressed indirectly when a user presses the button 14′ on the computer housing 11. Under the circumstances, the position of the button 14′ on the computer housing 11 has to be adjacent to that of the button 14 on the optical disc 1, and cannot be at any other position on the computer housing 11. Accordingly, the design of the computer housing 11 is not fashion enough to attract consumers.
It is therefore an important subject of the invention to provide an electronic apparatus and an optical drive for solving the above mentioned problem of positioning the button on the computer housing.
In view of the foregoing, the invention is to provide an electronic apparatus and an optical drive thereof, wherein a button for controlling the drive can be disposed at any position on a housing.
To achieve the above, an electronic apparatus of the invention includes an optical drive and a second housing. In the invention, the optical drive has a first housing, a circuit board, a first button and a second button. The circuit board is disposed in the first housing. The first button is disposed on the first housing and electrically connects to the circuit board. The optical drive is disposed in the second housing. The second button electrically connects to the circuit board with a wire and is disposed on the second housing for controlling the optical drive.

The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein:
The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.
First, please refer to FIGS. 2 to 4 for illustrating an electronic apparatus according to a preferred embodiment of the invention.
As shown in
In this embodiment, the second housing 31 is the computer housing, and the optical drive 20 is disposed in the second housing 31.
The optical drive 20 comprises a first housing 21, a circuit board 22, a first button 23 and a second button 24.
The circuit board 22 is disposed in the first housing 21. In this embodiment, the electronic apparatus 30 has a disc tray 32.
The first button 23 is disposed on the first housing 21 and electrically connects to the circuit board 22. By pressing the button 23, a first signal is transmitted to the circuit board 22. In this embodiment, the first signal may control the loading/ejection of the disc tray 32 for performing the loading/ejection action of the optical drive 20, or change the playing status of the optical drive 20 (a playing action).
The second button 24 can be disposed at any position on the second housing 31 and electrically connects to the circuit board 22 with a wire 25 for controlling the optical drive 20. The second button 24, by the connection of the wire 25, may be disposed at any position on the second housing 31 that the wire 25 can reach. In this embodiment, the wire 25 is a twist pair cable. A second signal is transmitted to the circuit board 22 when the second button 24 is pressed. The second signal may control the loading/ejection of the operating the disc tray 32 for performing the loading/ejection action of the optical drive 20, or change the playing status of the optical drive 20 (the playing action).
As shown in
As shown in
When a user presses the first button 23 on the first housing 21 and does not press the second button 24, the output terminal 224 transmits a first signal to the circuit board 22 to control the loading/ejection action or the playing action of the optical drive 20.
Further, when a user presses the second button 24 on the second housing 31, the output terminal 224 transmits a second signal to the circuit board 22 to control the loading/ejection action or the playing action of the optical drive 20.
In this case, the first and second signals, which are controlling signals outputted from the output terminal 224 of the OR gate 222, are use to control the loading/ejection of the disc tray 32 or the playing of the optical drive 20. The loading/ejection action of the optical drive 20 can be reached by operating the loading/ejection of the disc tray 32. For example, the disc in the optical drive 20 can be taken out after ejecting the disc tray 32, or the disc can be inserted into the optical drive 20 after placing the disc in the disc tray 32 and then inserting the disc tray 32. To control the playing of the optical drive 20 is to change the mode of the optical drive 20 from “Play Mode” to “Stop Mode” or to “Pause Mode”. Besides, the mode thereof could also be changed from “Stop Mode” or “Pause Mode” to “Play Mode”.
In this embodiment, the electronic apparatus 30 further comprises a connector 33, such as a jumper or a switch with separated positive and negative electrodes. The connector 33 electrically connects the wire 25 with the circuit board 22. Therefore, the controlling signal can be transmitted to the circuit board 22 from the second button 24 through the wire 25 and the connector 33.
