Patent Application
20050007350
The present invention relates in general to a wireless cursor-controlling device and, more particularly, to a wireless cursor-controlling device including a controller and a receiver, wherein the receiver can be stored in the controller for conveniently carrying, storing and using.
Conventional projectors using transparent sheets in a briefing or a seminar are inconvenient. Instead, using computers are more popular. A speaker can utilize the software installed in the computer to provide a dynamic and dramatic performance. Meanwhile, a wireless computer cursor-controlling device is provided for the speaker to control the computer via infrared (IR) or radio frequency (RF) transmission.
A conventional wireless cursor-controlling device includes a controller and a receiver, as shown in
However, the conventional wireless cursor-controlling device has the drawbacks as follows.
1. The controller 10a and the receiver 20a have to be used together, but they are separated and cannot be combined together; therefore, it may always happen to forget the receiver 20a when it is ready to use.
2. This kind of computer-related product is compact and sophisticated. That is, the receiver 20a is smaller for its portability; therefore, it may happen to lose without attention.
Therefore, there exist inconvenience and drawbacks for practically application of the above conventional connector structure. There is thus a substantial need to provide an improved connector structure that resolves the above drawbacks and can be used more conveniently and practically.
The present invention provides a wireless cursor-controlling device, which includes a controller having a containing space for receiving a receiver. It is convenient for storing, carrying and using.
The wireless cursor-controlling device provided by the present invention includes a controller and a receiver. The controller includes a main body and a cover. The main body includes a first containing space for placing at least one battery and a second containing space for placing the receiver.
These as well as other features of the present invention will become more apparent upon reference to the drawings wherein:
Please refer to
The controller 10 has a substantially rectangular shape with an easy handling portion. The front end of the controller 10 has an infrared transmitter. The controller 10 includes page-up and page-down buttons 101, a mouse button 102 and an enable button 103, as shown in
Furthermore, the controller 10 includes a main body 11 and a cover plate 12. There are a first containing space 13 and a second containing space 14 divided by an insulating plate 15 in the main body 11. The cover plate 12 is used to closely cover above the first and second containing space 13, 14. The separating plate 15 has a recess 151. The first containing space 13 is for placing the batteries 13.
The receiver 20 is for receiving the controlling signal transmitting from the controller 10, and can be put into the second containing space 14. There is a connecting portion 21 on one end of the receiver 20 to be connected to a corresponding port of the computer. In this preferred embodiment, the connecting portion 21 is a USB (universal serial bus) connector. A holding portion 141 is formed in the second containing space 14. The receiver 20 can be securely placed in the second containing space 14 by the holding portion 141. It is easy to take the receiver 20 out of the second containing space 14 for use.
Referring to
The resilient portion 30 can be a leaf spring as in this preferred embodiment or a spiral spring and etc. By using the leaf, the receiver 20 is placed on the resilient portion 30; therefore, while the cover 12 is removed from the main body 11, the receiver 20 will be raised by the resilient portion 30. As such, it is much easier to take out the receiver 20.
According to the wireless cursor-controlling device of the present invention, it provides at least the advantages as follows.
This disclosure provides exemplary embodiments of the present invention. The scope of the present invention is not limited by these exemplary embodiments. Numerous variations, whether explicitly provided for by the specification or implied by the specification, such as variations in structure, dimension, type of material and manufacturing process may be implemented by one of skill in the art in view of this disclosure.
