The support member 150 includes a first rotation shaft rod 151 and a second rotation shaft rod 151, And a support 153 rotatably coupled through the second rotary shaft rod 152, the first rotary shaft 151 and the second rotary shaft 152, and the like.

The support 153 coupled to the first rotary shaft 151 and the second rotary shaft 152 is formed of a resilient spring steel and corresponds to the support mount groove 116, The slope of the LED billiard can be made to be 30 or 45 degrees by rotating the support 153 to the outside and being supported by any one of the support protrusions 116a according to the inclination desired to be read, It is possible to read the book in a comfortable manner.

The cover member 160 is hingedly connected to the side surface of the body member 110 to cover the upper portion of the body member 110. The cover member 160 is provided in a shape corresponding to the body 111, A second fixture 162 for storing paper on the inner surface of the lid body 161, and the like.

Here, the lid body 161 may have a shape corresponding to the body 111 and a portion where the first fixture 115 provided at the upper portion of the body 111 is located.

In addition, the second fixing member 162 is provided at each corner portion in an elastic band manner to stably fix the paper to be used additionally, thereby improving the usability.

The control unit is provided inside the body member 110 to perform overall operation control on the electrical configuration such as the illuminance sensor 114, the light emitting member 120, the input member 130, the power supply member, and the like of the body member 110 When the power ON input signal is supplied from the first input button 131 of the input member 130, the power is supplied to the light emitting member 120 through the power supply member, When the power-off input signal is provided from the first input button 131, it is possible to control the power supply member to cut off power supply to the light-emitting member 120. [ The control unit is provided inside the body member 110 and is not shown in the drawings, but it is obvious to a person skilled in the art that the control unit can be practiced through the detailed description.

When the mode selection signal for selecting the light emitting mode is provided from the second input button 132 of the input member 130, the control unit controls the plurality of LED modules 121 of the light emitting member 120, As shown in FIGS. 5A to 5D, the light emitted from the light source can be displayed in the form of a horizontal underline, a vertical underline, a horizontal underline, a vertical underline (i.e., a document shape)

Here, when the control unit displays the island emission pattern, the island emission may be controlled to randomly select any one of the plurality of LED modules 121 to emit light.

For example, FIG. 5A illustrates the display of a horizontal underline using the LED billiard, FIG. 5B illustrates the display of the vertical underline using the LED billiard, and FIG. And FIG. 5D illustrates an island light emission pattern using an LED light bulb. In the case of the island light emission pattern, not all light is emitted, By doing so, eye movement can be done to help improve eye health.

Meanwhile, when the illuminance detection signal corresponding to the ambient brightness is provided from the illuminance sensor 114, the control unit controls the illuminance of the illuminance sensor 114 to be greater than the reference power supply amount It is possible to control the power supply to be supplied as much as the predetermined additional power supply and to supply the power supply more than the reference power supply through the power supply member so as to emit relatively stronger light than the reference power in the dark .

For example, when the illuminance sensed by the illuminance sensor 114 during the divergence of the light with the reference luminous intensity of 1000 cd is 1000 lx, which is the illuminance of the general office, the controller corresponds to a value larger than the sensed illuminance by a predetermined difference The power supply member and the light emitting member 120 can be controlled so that light is emitted at a light intensity of 1100 to 1150 cd (i.e., light is emitted with a stronger light intensity than the reference light intensity), and the light intensity sensor 114 (I.e., a relatively stronger light intensity than the reference light intensity), which is greater than the sensed light intensity when the illuminance sensed through the living room is 400 lx The power supply member and the light emitting member 120 can be controlled. Here, it goes without saying that such roughness and luminosity and its interval (i.e., luminosity as high as 100-150 cd at 400 cd corresponding to 400 lx) can be appropriately adjusted.

Accordingly, the present invention provides a light emitting mode corresponding to a horizontal underline, a vertical underline, and a pattern light emission selectively using an LED light source, so that it can be used even when a letter is written on an unlined paper, Lt; / RTI >

Also, according to the present invention, by controlling the light intensity of the LED light source through the illuminance sensor provided in the booklet, horizontal underline, vertical underline and pattern light emission can be generated according to the surrounding brightness to reduce fatigue of the eyes.

In this embodiment, the black film is applied on the front surface of the booklet so that the characters on the back side of the booklet can not be seen, or the black film is applied to the booklet, so that the underline, vertical underline and pattern light are generated, have.

In addition, the present invention can apply a non-slip material to the back side of the book cover, so that the user can write letters without slipping at any place, and a support member is provided on the back side of the book cover, And can be used in combination.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. It will be readily apparent that such substitutions, modifications, and alterations are possible.
