Abstract
Description
The present invention relates to an ultra-slim optical joystick, and more particularly, to an ultra-slim optical joystick capable of good assembly and miniaturization and slimming.
As a portable terminal, there are a notebook computer, a netbook computer, a mobile phone, a personal digital assistant (PDA), and the like. As an input device of these portable terminals, there is a small portable mouse.
The portable mouse has a mouse body and a mouse cable, and is used by being connected to a portable terminal as necessary.
However, such a conventional portable mouse (hereinafter, abbreviated as "mouse") is configured separately from the portable terminal, and thus has a disadvantage in that it is very inconvenient to carry. In particular, since a mouse cable for connecting with a mobile terminal is provided, there is a problem that handling and storage are more inconvenient.
In view of this, a mouse that has been miniaturized and slimmed and capable of wirelessly connecting to a portable terminal without a separate cable has been proposed.
An example is the "Ultra-slim wireless optical mouse usable for a portable computer system" of Korean Patent Application No. 10-2005-113202 filed by the present applicant.
As shown in FIG. 1, the technique includes a mouse
In particular, the
Since the mouse of such a structure employ | adopts the
In addition, since the movement of the cursor and the pointer is made through the movement of the finger, there is an advantage that it is very easy to use. In addition, wireless connection to the computer is possible, no separate cable is required. Therefore, it is easier to carry.
However, such a conventional mouse has a disadvantage in that assembly is inferior since components of the
In addition, the conventional mouse has a disadvantage in that the size of the
In addition, the conventional mouse has a structure in which a command is selected or executed only by moving a cursor, a pointer, etc. to a desired place using an
SUMMARY OF THE INVENTION The present invention has been made to solve such a conventional problem, and an object thereof is to provide an ultra-slim optical joystick that can improve the assemblability and shorten the assembly time by simplifying the assembly structure of the optical pointing device. There is.
Another object of the present invention is to provide an ultra-slim optical joystick that can be miniaturized and slimmed by improving the structure of the optical pointing device and slimming the size thereof.
Still another object of the present invention is to provide an ultra-slim optical joystick that is very easy to use by configuring a single optical pointing device to move a cursor and a pointer, as well as to select and execute an instruction.
In order to achieve the above object, the ultra-slim optical joystick of the present invention moves the cursor or the pointer on the display unit of the portable terminal through the movement of the subject, and can be retractably stored in the card slot of the portable terminal. An optical joystick including a wireless transceiver for wirelessly communicating with the portable terminal, comprising: a lower package having a light source member and an image sensor mounted at intervals on a substrate, and a transparent encapsulant sealing the light source member and the image sensor; Wow; An illumination system corresponding to the light source member to illuminate the infrared light of the light source member, a light guide system corresponding to the image sensor so as to image the infrared light reflected from the subject to the image sensor, and the illumination system and the light guide system An upper package having an outer light shielding material for sealing the seal; It is characterized in that it comprises a click switch to select or execute the object pointed to by the cursor or pointer while being switched as the upper and lower packages are pressed.
Preferably, the light guide system is characterized in that the fiber (Fiber). The optical guide system may be an optical fiber having a multicore structure including a plurality of cores and a cladding surrounding the plurality of cores, and a plurality of single-core optical fibers including a single core and a cladding surrounding the single core. It may also consist of two bundles.
According to the ultra-slim optical joystick according to the present invention, since the assembly structure is simplified, the assemblability of the whole mouse is improved and the assembly time is greatly shortened. Therefore, the production efficiency is increased, the cost reduction effect can be expected.
In addition, since the structure can be made slimmer, there is an effect that the overall size of the mouse can be made smaller and slim.
In addition, since a single device can move a cursor and a pointer, as well as select and execute a command, it is very easy to use.
Hereinafter, exemplary embodiments of an ultra-slim optical joystick according to the present invention will be described in detail with reference to the accompanying drawings.
First, prior to looking at the features of the ultra-slim light joystick according to the present invention, the wireless light joystick is briefly described with reference to FIGS. 2 and 3.
