Abstract
A dimmer includes a window panel connected to a viewing screen area of a device with light-shielding plates provided thereon, the light-shielding plates including a plurality of plates respectively hinged at window edges of the window panel. A window of the window panel is closed off when each plate is folded, while a light-shielding structure is formed in front of the screen when each plate is straightened up. Torsion springs or the like automatically straighten up the left and right side plates and are respectively provided at hinged positions of the two plates and the like. A flat-plate magnifying lens, whose pulled-out end projects from the edge opposite to the hinged edge of the upper plate is slidably fitted in a sandwiched cavity. The flat-plate lens is positioned right in front of the screen when it is pulled out and folded downwardly.

Referring to FIGS. 1-4, a dimmer for LCD screen of a digital camera according to an embodiment includes a window panel 1 connected to LCD screen area of the digital camera and light-shielding plates disposed on the window panel 1, the light-shielding plates consisting of an upper plate 2, a left side plate 3, a right side plate 4 respectively hinged at corresponding window edges of the window panel 1. A window of the window panel is closed off when each of the plates 2,3,4 is folded, as shown in FIG. 2, while a canopy-shaped structure is formed in front of the LCD screen when each of the plates 2,3,4 is straightened up, as shown in FIG. 1, wherein torsion springs 5 or the like for automatically straightening up the left side plate 3 and the right side plate 4 are respectively arranged at the hinged positions of the two above-mentioned plates, and a magnetic attraction part 7 to be attractively fixed to the window panel 1 is provided at the non-hinged edge 6 of the upper plate 2. A sandwiched cavity 8 is provided inside the upper plate 2, and a flat-plate lens 9 for magnifying, whose pulled-out end projects from the edge opposite to the hinged edge of the upper plate 2, is slidably fitted in the cavity 8. The flat-plate lens 9 is positioned right in front of the LCD screen when it is pulled out and folded downwardly, as shown in FIG. 4.


Referring to FIGS. 5-8, a dimmer for LCD screen of a digital camera according to another exemplary embodiment differs from that shown in FIGS. 1-4 in that light-shielding plates of the dimmer consist of an upper plate 12, a left side plate 13, a right side plate 14 and a lower plate 15 respectively hinged at the window edges of the window panel 11. A rectangular sight tube is formed in front of the LCD screen when each of the plates 12,13,14,15 is straightened up. A torsion spring 16 or the like for automatically straightening up the lower plate 15 is provided at the hinged position of the lower plate 15. Other structures are identical with those of the dimmer for LCD screen of the digital camera as shown in FIGS. 1-4.


When the above-mentioned dimmers is provided in the state as shown in FIG. 4 or FIG. 8, it is possible to see the magnified picture on the LCD screen of the digital camera clearly from the flat-plate lens 9 or 17.


While the invention has been described with reference to one or more exemplary embodiments, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted for elements thereof without departing from the scope of the invention. In addition, many modifications may be made to adapt a particular situation or material to the teachings of the invention without departing from the essential scope thereof. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed as the best mode contemplated for carrying out this invention, but that the invention will include all embodiments falling within the scope of the appended claims.
