As shown in FIG. 1, the reading enlarger 100 of the present invention has a link arm (1) composed of a main body 110, a vertical support 121, a horizontal support 122, and a plurality of link sections 123a, 123b, and 123c. The support frame includes a 123, a display device 140 connected to one end of the support frame, and an operation panel 130 electrically connected to the main body 110.

The main body 110 includes a lower plate 112 in which a circuit board including the central processing unit 200 is embedded, and an upper plate 111 slidably mounted on the lower plate. The upper plate 111 is mounted to be slidably up and down and left and right on the lower plate 112, and protrudes a guide rail (not shown) on the lower plate 122 and corresponds to the guide rail on the bottom surface of the upper plate 111 The guide groove (not shown) can be configured to be slidably movable by the operation of the drive motor, it is also possible to configure a sliding movement by adopting a linear linear motor. On the top plate 111, print media such as books, magazines or newspapers are placed.

The vertical support 121 is coupled to the main body 110 and extends from the vertical support 121 to form a horizontal support 122 horizontally on the bottom surface. One side of the link arm 123 formed of a plurality of link sections 123a, 123b, and 123c is coupled to the vertical support 121. The other side of the link arm 123, the display device 140 is coupled.

As the display device 140, a screen display device such as a liquid crystal display (LCD) is used, and its position or angle can be freely adjusted by the link clause of the link arm 123.

The camera 151 and the LED light 152 are attached below the horizontal support 122 of the support frame. The camera 151 is used to capture and enlarge the type of the print medium on the upper plate 111, and preferably has a macro lens.

The LED lighting is installed at a predetermined distance apart from the camera 151 at a predetermined distance, and is for illuminating the print medium on the upper plate 111 at night or in a dark indoor environment.

An operating circuit 130 having a plurality of function buttons is connected to an internal circuit board of the main body 110. The operation panel 130 has a main power switch 131, an LED light on / off switch 132, screen left and right scroll button 133, screen up and down scroll button 134, screen zoom button 135, lens zoom in The / zoom out button 136, the upper and lower left and right movement button 137, the upper and upper movement button 138 is provided.

The screen left and right scroll buttons 133 are used to move an image of the enlarged letter displayed on the display device 140 by turning the button left and right, and read a book from left to right or right to left.

The screen up and down scroll button 134 is to move the image of the enlarged type from the top to the bottom or up from the bottom to read down in order from the top to bottom of the book.

The screen enlargement / reduction button 135 is used to adjust the magnification of the magnification type displayed on the display device 140. The size magnification of the magnification of the magnification of the magnification of the enlarged type is adjusted by simply turning the button left or right. The screen enlargement / reduction function of this function is a simple magnification or reduction of the screen image captured by the camera 151 at a constant magnification and displayed on the display device 140. Since the function of simply enlarging or reducing an image in a device such as an LCD monitor is a well-known technique, a detailed description thereof will be omitted.

The lens zoom-in / zoom-out button 136 is for adjusting a magnification by zooming in or out of a lens of the camera 151 attached to the horizontal support 122. The above-described screen enlargement / reduction button 135 is used to simply display or enlarge the reduced type image of the photographed type image by software. However, the button of the present function enlarges or reduces the type of the letter type itself and then displays the image. This is to manifest itself at that magnification. Therefore, when the printing is enlarged or reduced by the function button, the resolution of the image displayed on the screen is kept constant, thereby obtaining a clear image.

The left and right movement button 137 and the up and down movement button 138 moves the upper plate 111 on which the reading distance of a book, etc., is raised, up, down, left and right, and places the enlarged portion of the contents of the book directly under the camera. It is for. Even if there is no such function button, the camera 151 can fully capture the entire surface of the book and display it by enlarging the entire image. However, the image of the typeface image taken may be distorted depending on the shape or state of the book. This is to prevent the phenomenon.

In the present invention, the image of the enlarged letter displayed on the display device 140 described above may be implemented by a touch screen method. In other words, when the user touches the screen to scroll up, down, left, or right, the image is scrolled up, down, left, and right to perform a function such as reading a book naturally. Such a function is particularly useful for users such as the elderly.

The touch screen function can be implemented using an analog resistive film method, which is the most common method among the touch screen methods. The display device 140 may be equipped with a touch panel. The touch panel is composed of a glass and a film on which a transparent conductive film (ITO) is deposited. Analog X and Y signals may be transmitted to the touch controller 232. The electrical analog signal transmitted from the touch panel is digitized by the A / D converter of the touch controller 232 and transmitted to the touch driver 233. The touch driver 233 is a kind of software that is optimized to receive a digital signal from the touch controller 232 and implement the touch panel in accordance with the reading enlarger.

The touch screen may be implemented using a capacitive method in addition to the analog resistive film described above. The capacitive touch screen is composed of glass coated with indium tin oxide (In2O3 + SnO2), which is a conductive compound of indium and tin oxide, and attaches a sensor to a corner of the glass and continuously applies current to the glass. As it flows, the sensor accumulates charge precisely in the transverse and longitudinal directions. Therefore, when the touch screen is pressed by a human finger, electrons flowing in the glass move to the body, and the touch screen function is performed by a sensor detecting the change of the electrons and measuring coordinates.

In addition, an ultrasonic touch screen and four touch screens are equipped with sound wave transmitters and sound wave receivers at four vertices of the touch screen, and then the coordinate plane is formed on the surface of the touch screen using a reflector to measure the coordinates by the disturbance of the wavelength caused by the object to touch the screen. Touch of the display device 140 by an infrared touch screen for measuring coordinates by the flow of infrared rays that the object to be touched by making a coordinate plane on the surface of the touch screen by mounting a photo transistor and an infrared LED facing each other. It might be possible to implement screen functionality.

In the present invention, using the voice receiving device 141, such as a microphone, the vertical and horizontal scrolling function and the enlargement / reduction function of the enlarged type image are also implemented by the user's voice command. The food recognition function is such that the voice signal control unit 251 connected to the CPU 200 receives and compares the voice frequency input through the voice receiver 141 such as a microphone to perform a corresponding command. It is implemented, it can be carried out using a conventionally known technique.

Speech recognition algorithms include dynamic time warping (DTW), a method of determining similarity by comparing a representative pattern with a given input pattern, and a transition probability modeling the temporal change of speech and an output probability modeling the spectral change. Hidden Markov Model (HMM), which calculates the similarity of a model using probabilistic estimates with a given model, rather than using similarity between input and output patterns, and the human brain encrypts and decrypts information. There is a method such as a neural network (Neural Network) using a neural network modeled in the engineering aspect of the process, and the details of these techniques are well known techniques, so a detailed description thereof will be omitted.
