The present invention relates to an apparatus for implementing a presentation function of a portable composite terminal. In particular, the present invention relates to a display device for controlling an external imaging apparatus. The present invention relates to a portable composite terminal capable of outputting contents stored in the portable composite terminal to an external image apparatus connected thereto. The present invention relates to an apparatus for implementing a presentation function.

In recent years, portable composite terminals collectively referred to as high-end mobile phones, PDAs (Personal Digital Assistants), smart phones, and the like have improved performance of main CPUs and sub-CPUs and storage space of flash memory. Various functions such as augmentation and 2D / 3D graphics are concentrated to serve as a multimedia terminal, not merely providing a voice call service.

In such a portable composite terminal, the basic unit of all the data can utilize the characteristics of the same digital data to store data such as games, MP3s, photos, etc. in the same storage space and can be driven by a single CPU.

Therefore, the mobile handheld terminal that will emerge in the future has a fast 400MHz class CPU, more than 64MB of storage space, and more than one display is expected to be equipped with a powerful operating system (OS) such as WinCE, Symbian, Palm.

However, according to the related art, a function of presenting a portable composite terminal by connecting it to another video device has not been developed. In general, presentation refers to the presentation of research contents, the presentation of a plan or business description, the presentation at a seminar, etc., and the presentation of a claim or opinion to a large number of people.

If you need to provide a large number of people with the materials you need for your presentation, use handouts, use briefing charts, slider projectors, and OHP. In recent years, many projectors are easy to use and have various functions. A projector is a device that converts certain screen data into an image that can be recognized by people, and is commonly used by connecting to a computer or a similar device.

In this case, the portable computer is mainly connected to an external display device such as a projector, but even when using a portable computer, it is inconvenient to carry due to its bulky and heavy weight, and to output a small amount of screen data. There is an inconvenience in carrying the computer itself.

In addition, if space is limited, for example, when the projector is far away, the presenter cannot directly operate the portable computer. Therefore, a separate person other than the presenter may be required because a person who needs to operate the portable computer will be required as the presentation proceeds. This was a necessary problem.

In addition, the screen information of the portable computer should be switched as the presenter progresses, and as the two people progress, the presenter and the computer operator have an inconvenience in needing an effort to match such a motive with a glance or a hand signal.

In order to overcome this, various applications that attempt to overcome the limitation of the size of the display window of the mobile communication terminal by having a projection (projection) function as shown in FIG. Number: 20-

0263336).

However, the above-mentioned conventional applications suggest only the technical concept of adding only a projection function to the mobile communication terminal, and the conventional application of the present invention should handle the hair work having a built-in projector directly, or fix the mobile and operate it through a key button. As a result, there is considerable inconvenience in operating the program for presentation or using the mobile Internet.

That is, it is urgent that a mouse pointer is required for the operation of the mobile program separately from the mobile functioning as a projector for easy operation of the mobile program projected on the external screen.

An object of the present invention to solve the above problems is to implement a device that can be easily detached and detached, and independently connected to the terminal to perform the function of a mouse or a pointer, easy to carry a projector-type wireless communication terminal To provide.

An aspect of the present invention for solving the above problems includes a keypad including a plurality of number keys and numeric keys, a display unit on which data or applications are output and displayed, and a control circuit unit for controlling and processing the data or application. In the mobile communication terminal is configured to receive the projector module coupled to the mobile communication terminal body, the optical mouse pointer for input of the mobile communication terminal, and receives the light reflected from the optical mouse pointer to convert the input signal A light receiving switch; And an optical fiber for guiding light by connecting the optical mouse pointer and the light receiving switch.

Here, the optical mouse pointer is a pen mouse shape that can be attached to or detached from the longitudinal groove located on the side of the terminal, the light source for generating a laser light on the contact portion of the pointer and the light reflected by the irradiated laser light. It is preferable to include a light receiving unit to collect and deliver to the light conversion unit.

Preferably, the optical mouse pointer has a box shape in which a user's finger insertion groove is formed, and collects a light source for generating a laser light and a light reflected by the irradiated laser light on a contact portion of the pointer to receive the light. It may include a light-receiving unit for transmitting to the part, the box-type pointer may be a box-type module that can be separated into the optical fiber and the socket.

Furthermore, the optical fiber is preferably coated with the outside of the rubber material.

By providing the present invention, not only can be displayed on the screen several tens of times larger than the LCD screen, but also can easily operate the program with the optical mouse pointer connected to the terminal, it is possible to perform the function of a large portion of the PC Will be obtained. In addition, the terminal can be easily attached and detached, thereby making it easy to carry.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

2 is a diagram illustrating the configuration of a projector-type mobile communication terminal according to the present invention. As shown in FIG. 2, the projector-type mobile communication terminal 100 includes all the configurations of a conventional mobile communication terminal, and further includes an optical module pointer 200 that is a projector module and an input device.

Conventionally, since there is no input device other than the keypad or the touch pad of the terminal, when the terminal is fixed and the image is projected on the screen at a certain distance, there is a difficulty in operating an application program that provides the image.

In other words, it is inconvenient in that it can only be operated by pressing a key button while directly projecting the terminal with a hand and projecting it, or it can only be input by operation through a key button in a fixed state. It was quite inconvenient if enemy manipulation was required.

In view of the above, in the present invention, if the present invention has a configuration including an input device such as a mouse in addition to a key button or a keypad, the terminal can be input as if the mouse is operated while the projected image is fixed while the terminal is fixed for the projection of the image. A configuration including an optical mouse pointer 200 is proposed.

As shown in FIG. 2, the present invention is composed of a general mobile communication terminal, a projector module, and an optical mouse pointer 200. The projector module includes a photographing system unit 110 and an image processing unit which are configured as an optical system such as a lens. And a control unit. (Not shown) Here, the projection lens of the optical system unit is preferably provided at the upper end or the upper side of the terminal. Alternatively, it is preferable to protrude and install the upper side of the terminal, and to configure the hinge to be rotatable at a predetermined angle.

In the projector, it is necessary to adjust the projection lens in order to easily find and project the screen in various places as well as the screen focus.

In this way, the application program image of the terminal is converted into the image data by the image processing unit, and the projector module is configured to be projected on the screen through the lens through the control unit.

The optical mouse pointer 200 serves as a mouse which is an input device of a general terminal. When the optical mouse pointer is used as an input device by connecting an externally operable optical mouse pointer to the mobile communication terminal 100, the terminal can be stably used. After fixing and projecting the image on the screen 400, the user can conveniently operate the program as a mouse, there is an advantage that can be easily operated when a lot of input operations such as presentation or Internet web surfing is required.

Mobile communication terminals such as mobile phones have been developed to perform almost PC functions such as miniaturization and high integration of memory due to the development of semiconductor technology and IT technology. However, due to the size of the output device and the limitation of the input device, the mobile communication terminal has difficulty in executing or operating an application program executed in a general PC. Therefore, when using the projector and the optical mouse pointer 200 of the present invention, there is an advantage that can be obtained, such as carrying out work while carrying a PC and beam projector.

By projecting the image output from the liquid crystal display only a few inches by the projector built in the terminal on the screen by maintaining a certain distance, not only can be displayed on the screen several times to several tens of times, the optical mouse pointer 200 connected to the terminal The program can be operated easily, so that the functions of all the functions of the PC can be performed.

3 is a diagram illustrating a configuration of the pen mouse-type optical mouse pointer 200 as an embodiment according to the present invention. As shown in FIG. 3, the optical mouse pointer includes a light source 210 for generating a laser light, a light receiving unit 220 for irradiating the generated laser light and collecting light reflected from a contact surface, and a switching unit for selecting a cursor. do.

The light source is preferably a laser light source. This is more effective in the case of the optical mouse using the principle of extracting the information data by the surface reflected light because the laser light has good monochromaticity, coherence, high brightness, directivity, and energy concentration. Is improved, but the laser light mask shows high sensitivity even on various surfaces.

The light receiving unit 220 collects the laser light reflected on the surface and transmits the laser light to the light receiving switching unit mounted in the terminal through the optical guide 140 as the light guide. The introduction portion of the light receiving portion 220 has a larger area than the optical fiber to facilitate light collection, and when the cone shape or the taper shape is taken, the reflected laser light can be collected more effectively.

Since the mouse not only adjusts the movement of the cursor for determining the position on the screen to be displayed, but also needs to select a folder or an icon in a specific part, the mouse needs a switching signal for a click because it takes a selection signal. In the present invention, as shown in Figure 3, the ball 250, such as a light-transmissive resin to the contact end of the pen mouse is configured to act as a switching role when pressed by the elastic body.

Here, the contact portion may use a translucent resin to improve the feeling of contact, but may also be the case of a cylindrical tip made of a soft rubber material in which holes are formed so as to transmit or reflect the laser light.

In addition, the optical fiber 140 is preferably connected to the side by side with the conductive wires in order to transfer the electrical signal of the above-described switching unit. This is because the conducting wire not only supplies power to the light source mounted on the optical mouse pointer, but also transmits an electrical signal by switching to the main circuit of the terminal.

As described above, the pen mouse-type optical mouse pointer 200 having the above configuration is connected to the terminal 100 by an optical fiber, but in order to increase portability, a longitudinal groove is formed on the side of the terminal 100. It is preferable to form and store or mount the pointer. This is because it reduces the inconvenience of carrying and carrying the optical mouse pointer 200 separately, and can be conveniently used by leaving the terminal 100 when necessary.

In addition, another feature of the present invention is that the optical mouse pointer 200 merely reflects and collects and transmits light, and does not perform the function of a mouse that recognizes a position in the pointer itself and converts it into a digital signal. . As shown in Figure 2, in the present invention, the optical signal transmitted through the optical fiber recognizes the position on the screen by the ground contact by the light receiving conversion unit built in the terminal, and converts it into a digital signal to convert the input signal of the terminal Create

In this configuration, the optical mouse pointer 200 may be configured only by the light source, the light receiving unit 220 and the switching by mounting the light receiving conversion unit inside the terminal and connecting the optical mouse pointer and the optical fiber 140 separated from the terminal. In this regard, there is an advantage in that the optical mouse pointer 200 can be easily manufactured.

4 is a diagram illustrating a configuration of a box-type optical mouse pointer as an embodiment according to the present invention. As shown in FIG. 4, the pointer 300 is formed in a box-shaped constant groove to fit a user's finger, and includes a light source 310, a light receiving unit 320, and a switching unit. Descriptions of the light source 310, the light receiving unit 320, and the switching will be omitted with the same configuration as the invention illustrated in FIG. 2.

The box-type optical mouse pointer illustrated in FIG. 4 is a structure that can be conveniently inserted and used by a user's finger. The box-type optical mouse pointer can be manipulated by the movement of a finger and can be detached and detached. (100) It can be easily carried by connecting to the ring. In addition, it is also preferable that the box-shaped pointer 300 can be worn on the user's finger by attaching a ring-shaped ring to the side without forming a groove.

As described above, the present invention can easily operate the application program by fixing the terminal by connecting the optical mouse pointer to the optical fiber, and as shown in Figure 3, by using it by inserting the finger, not only can be conveniently used, but also small size The optical mouse pointer 300 has the advantage of being convenient to carry.
