Description

Assignment structure for wireless cursor transmitter {ALLOCATION STRUCTURE FOR WIRELESS CURSOR TRANSMITTER}

The present invention relates to an allocation structure for a wireless cursor transmitter, and more particularly to a wireless cursor transmitter that can be integrated into a portable computer.

In the past, projectors and slides were often used for presentations in conferences and seminars. The development of information technology has replaced conventional projectors or slides with computers and peripherals. Using a computer for presentation has become a common trend in conferences and seminars because the computer provides sound and dynamic visual effects to make the presentation look more attractive. Another advantage of computer presentation includes that information stored on a computer can be updated and changed at any time. Thus, computers, especially portable computers, have become indispensable tools for business in modern society.

1 shows a conventional portable computer 10a and transmitter 20a. The portable computer 10a includes a connection port 11a for plugging in the receiver 12a. The receiver 12a serves as a receiver for radio frequency signals. The transmitter 20a includes a power switch and a plurality of push buttons. By pressing the button, the cursor position is controlled remotely, and the signal generated by calculating the displacement value of the cursor is transmitted to the computer host via radio frequency such that the cursor on the screen is displaced.

The conventional portable computer 10a and the transmitter 20a remotely control the computer software for presentation. During application, the transmitter 20a is carried by the user and at the same time the portable computer 10a can be placed on the podium. However, when both devices are not used, the storage of the portable computer 10a and the transmitter 20a is independent of each other. Therefore, the transmitter 20a often forgets or loses the place.

The present invention provides an allocation structure of a wireless cursor transmitter. An expansion slot in a portable computer is used to assign the transmitter so that it can be stored with the computer when the transmitter is idle. Thus, access and storage are much more convenient.

The allocation structure of the wireless cursor transmitter provided by the present invention includes a card having a plurality of push buttons formed on its top face. One end of the card may be connected to an expansion slot of the portable computer and has a disposable connection.

2 is an exploded perspective view illustrating an allocation structure of a wireless cursor transmitter, and FIG. 3 is an enlarged view of region A illustrated in FIG. 2. 2 illustrates a portable computer 10 and a transmitter 20 disposed within the portable computer 10.

The portable computer 10 includes at least one expansion slot 11 which is, for example, a PCMCIA expansion slot for connecting a network card, a modem card or a sound card. The expansion slot 11 includes a common socket 12, and a push lever 13 is installed below the expansion slot 11. One side of the portable computer 10 includes a connection port 14 (shown in detail as USB). The connection port 14 provides a connection for the receiver 15 which functions as a receiving device for radio frequency signals.

The transmitter 20 includes a portable device that uses infrared (IR) or radio frequency (RF) signals to remotely control the position of the cursor on the computer screen. The front side of the transmitter 20 includes function keys such as page up, down and scrolling keys 201, left and right keys 202 and enable keys 203. Thus, the user can remotely apply computer applications such as PowerPoint for presentations.

In the present invention, the transmitter 20 comprises a card 21 which can be inserted into an expansion slot 11 of a portable computer. One end of the card 21 includes a connection part 22. The connection part 22 includes a female plug of PCMCIA for engaging with a male socket 12 located inside the expansion slot 11. In addition, a power pin may be formed on the connection part 22. Thereafter, the power pin is connected to a power terminal of the socket 12 to charge the transmitter 20.

4 illustrates the assembly of a portable computer and transmitter 20. As shown, the card 21 is gradually inserted into the expansion slot 11 until the connection part 22 of the card 21 is connected to the socket 12.

5 shows an operating state of the portable computer 10 and the transmitter 20. In application, the lever 13 of the portable computer 10 is pressed to extract the transmitter 20. Thereafter, the receiver 15 is plugged into the connection port 14 of the portable computer 10. By pressing the enable key 203 of the transmitter 20, the cursor displacement control function is activated. Thereby, the displacement of the cursor on the screen can be controlled remotely.

Therefore, the allocation structure of the wireless cursor transmitter provides the following advantages.

1. Since the expansion slot of the portable computer is suitable for accommodating the transmitter, the convenience of access, storage and carrying of the transmitter is greatly improved.

2. The connection part of the transmitter can be integrated with the portable computer to prevent the transmitter from being lost and forgotten.

This description provides a legendary embodiment of the present invention. The scope of this description is not limited by such a legendary embodiment. Although expressly provided or implied by the specification, numerous modifications may be made by one of ordinary skill in the art in view of this description, such as variations in shape, dimensions, material type, or fabrication process.
