Best Mode for Carrying Out the Invention The present invention will now be described in detail in connection with preferred embodiments with reference to the accompanying drawings.

First Embodiment Referring to FIG. 1 a LCD hood 5 in a digital camera 1 according to a first embodiment of the present invention has a rubber 9 attached to its bottom. The rubber 9 has a rectangular

cross section, which is mated with the shape of the LCD, and is closely adhered to the peripheral of the LCD. Further, the LCD hood 5 further includes an adjustment means for fixing the LCD hood to a spiral flute 42 to which a triangular pole of the digital camera 1 is fixed in order to adjust the position of the digital camera 1.

This adjustment means includes a vertical guide element 10 and a guide element 14 for adjusting the height of the hood 5, and a link 19 for allowing the adjustment means to move on a plane vertical to the height direction. A lever 30 for fixing the hood 5 when the position of the hood 5 is identical to the LCD, and a screw 40 for fixing the link 19 to the spiral flute 42 to which the triangular pole of the digital camera is fixed, are connected by an auxiliary means.

The vertical guide element 10 being the adjustment means for adjusting the height is integrally attached to a lateral side of the hood 5. The guide element 10 is thus inserted to the guide element 14, so that the hood 5 makes a sliding motion.

A rectilinear groove 11 for a sliding motion and a hanging protrusion 12 for preventing the motion are formed in the vertical guide element 10. The inside of the lateral side of the hood 5 in which the hanging protrusion 12 is formed is penetrated so that it has an elastic force by which the hanging protrusion 12 is inwardly

pushed and is then restored by a predetermined force.

The guide element 14 into which the vertical guide element 10 is inserted is coupled to the link 19. The hood 5 further includes a square protrusion 15 inserted into the rectilinear groove 11 of the vertical guide element 10 and a hanging uneven element 17 for preventing the bood 5 from easily moving by the hanging protrusion 12.

The link 19 includes an upper flat bar 23 to which the guide element 14 is connected, and a lower flat bar 23 connected to the upper flat bar 23 by means of a pin 27. Each of the upper flat bar 23 and the lower flat bar 23 has a through groove 25 formed therein, through which the pin 27 penetrates. Thus, the upper flat bar 23 and the lower flat bar 23 can make a sliding motion reciprocally through the through groove 25. A lever 30 for closely adhering the upper flat bar 23 and the lower flat bar 23 to fix the location of the hood 5. is hinged to a lower portion of the pin 27. A cam 35 formed at a portion where the lever 30 is connected to the pin 27 is brought into contact with the bottom of the lower flat bar 23. If the lever 30 rotates, the length of the pin 27, which penetrates the upper flat bar 23 and the lower flat bar 23, is shortened due to a difference in a thickness that the lever 30 rotary axis of the cam 35 and the lower flat bar 23 and the cam 35 are brought into contact

with each other. Consequently, the upper flat bar 23 and the lower flat bar 23 are closely adhered each other. The spiral flute 42 for allowing the triangular pole to be attached thereto, is formed in a screw 40 for fixing the link 19 to the spiral flute 42 of the digital camera 1 via the end of the upper flat bar 23.

Meanwhile unexplained reference numeral 45 designates a clamp ring 45 for making the screw 40 connected to the link 19 even before the screw 40 is attached to the spiral flute 42 through the link 19.

As shown in FIG. 2 and FIG. 3, in the LCD hood 5 in the digital camera according to the first embodiment of the present invention, if the lower flat bar 23 of the link 19 is attached to the spiral flute 42 formed at the lower side of the digital camera 1 by means of the screw 40, the height of the hood 5 is adjusted according to the guide element 14 in order for the LCD of the digital camera to be clearly seen, and the location of the hood 5 is fixed by adjusting the link 19 onto a plane location and turning over the lever 30, it is possible to preclude light from being incident to the LCD of the digital camera.
