  The hood body 1 has been described above. By the way, as shown in FIG. 9, a lens body 30 for enlarging and displaying an image projected on the liquid crystal screen is detachably attached to the front end portion of the light shielding portion 20 as needed. The lens body 30 includes a thin plate-shaped lens plate 31 that is substantially the same size as the liquid crystal screen Q and a lens holding frame 32 that holds the lens plate 31. In the present embodiment, the lens plate 31 is a plastic Fresnel lens having a performance as a convex lens having a magnification of about 1.5 to 2 times.

The lens holding frame 32 includes a holding frame main body 33 and a frame-shaped lens retainer 34 fixed to the front side of the holding frame main body 33 via a lens plate 31. As shown in FIG. 11A, the holding frame main body 33 is formed in a frame shape slightly larger than the lens plate 31 by a plastic resin. A lens mounting portion 33a is formed on the inner peripheral portion of the front side surface of the holding frame main body 33. The lens mounting portion 33a is dropped from the periphery by the thickness of the lens plate 31, and the lens plate 31 is formed on the lens mounting portion 33a. Is inserted. Similarly, mounting holes 33b and 33b for fixing the lens retainer 34 to the holding frame main body 33 are formed at predetermined positions on the front side surface.
Further, as shown in FIG. 11 (b), the holding frame main body 33 has a fitting grip part having fitting grooves 35a having substantially the same width as the thickness of the side plates 22 and 23 of the light shielding part 20 on the base side of the side part thereof. The lens body 30 is attached and fixed to the hood body 1 by fitting the front end portions of the side plates 22 and 23 of the light shielding portion 20 into the fitting groove 35a of the attachment grip portion 35.

By attaching and fixing the lens retainer 34 to the lens, it is held by the lens holding frame 32 as shown in FIG.

  Thus, by making the lens body 30 detachable with respect to the hood body 1, it is easy to confirm the image displayed on the liquid crystal screen Q. That is, the size of the liquid crystal screen of the digital cameras in circulation is as small as 1.8 to 2.0 inches, and it is difficult to check the details of the image when checking the captured image.

  Therefore, by attaching the lens body 30 to the tip of the hood body 1 and displaying an enlarged image displayed on the liquid crystal screen Q, it becomes easy to confirm details of the photographed image. Even if the lens body 30 is attached to the tip of the light shielding portion 20, the problem of incident light on the lens body 30 is unlikely to occur when confirming an image. That is, in the case of a digital camera, since the position and orientation of the digital camera are also determined from the positional relationship with the subject to be photographed, there is a case where light shielding is necessary in relation to incident light such as sunlight. . However, since the position, orientation, etc. of the digital camera are not specified when confirming the captured image, the digital camera can be moved to a position, or orientation, where the liquid crystal screen does not need to be shielded.

  Since the lens body 30 is detachable, it can be removed when the lens body 30 is unnecessary, such as during photographing, so that it can be used properly depending on the situation, such as photographing and image confirmation. In addition, by holding the side plates 22 and 23 by the lens holding frame 32, the open state of the light shielding portion 20 is reliably maintained, and the function as a magnifying glass can be reliably performed.

  The embodiment of the present invention has been described above. In the above embodiment, a digital camera has been described as an example of the liquid crystal device. However, the object to which the light shielding hood for liquid crystal equipment according to the present invention is attached is not limited to this, and a portable information terminal such as a video camera, a cellular phone, a PHS, a portable game machine, a portable TV, a vehicle navigator, and a PDA. Any liquid crystal device having a liquid crystal screen can be widely applied.
