Auxiliary image-observing device for portable liquid crystal display system

Claim 2

The image observing auxiliary instrument according to claim 1, wherein said magnifying lens has a plane shape having an area approximately equal to or larger than that of said liquid crystal display, and said holding frame has an opening in the same plane shape as that of said magnifying lens.

Claim 3

The image observing auxiliary instrument according to claim 1, wherein said mounting member has a mounting portion for allowing said portable liquid crystal display apparatus to be mounted on the mounting member with a part thereof being engaged with the mounting member.

Claim 4

The image observing auxiliary instrument according to claim 3, wherein said mounting member is provided with a rotatably supporting member for rotatably supporting said holding frame on the mounting member such that said holding frame can be superimposed on the mounting member at the time of folding and an angle which the magnifying lens fixed to said holding frame and the liquid crystal display form can be adjusted.

Claim 5

The image observing auxiliary instrument according to claim 3, wherein the mounting portion of said mounting member is a recess portion which is provided in a position spaced apart from a portion, which supports said holding frame, of the mounting member by a predetermined distance and to and with which one end of said portable liquid crystal display apparatus in the vicinity of a portion containing the liquid crystal display is to be inserted and engaged.

Claim 6

An image observing auxiliary instrument used for a portable liquid crystal display apparatus or the like comprising a housing having an opening formed in a part of its surface and a liquid crystal display contained in the housing so as to be visually observed from the outside through the opening, which comprises: a magnifying lens for enlarging an image reflected in said liquid crystal display; a holding frame for fixedly holding said magnifying lens; a mounting member connected to said holding frame for allowing the magnifying lens to face an upper position of said liquid crystal display such that said magnifying lens is opposed to said liquid crystal display as well as detachably mounting said holding frame on the housing of said liquid crystal display apparatus; and illuminating means mounted on said holding frame such that a screen of the liquid crystal display is made bright when the image reflected in said liquid crystal display is observed in an enlarged manner by the magnifying lens.

Claim 7

The image observing auxiliary instrument according to claim 6, wherein said mounting member has a mounting portion for mounting said portable liquid crystal display apparatus on the mounting member with a part thereof being engaged with the mounting member.

Claim 8

The image observing auxiliary instrument according to claim 7, wherein said mounting member is provided with a rotatably supporting member for rotatably supporting said holding frame on the mounting member such that said holding frame can be superimposed on the mounting member at the time of folding and an angle which the magnifying lens fixed to said holding frame and the liquid crystal display form can be adjusted.

Claim 9

The image observing auxiliary instrument according to claim 8, which further comprises dry cells for supplying power to said illuminating means, said mounting member being provided with a dry cell containing portion for containing said dry cells.

Claim 10

The image observing auxiliary instrument according to claim 9, wherein said dry cell containing portion comprises a dry cell containing recess portion for containing dry cells and a dry cell cover for closing the dry cell containing recess portion, said dry cell containing portion being formed in such a position as not to prevent said holding frame from being superimposed on said mounting member at the time of folding.

Claim 11

The image observing auxiliary instrument according to claim 10, which further comprises a power switch for turning the supply of power from said dry cells to said illuminating means on and off.

Claim 12

The image observing auxiliary instrument according to claim 11, wherein said power switch comprises a first contact provided in said mounting member and formed related to the rotatably supporting portion of said mounting member for further supplying power from a power supply line through said power switch, and a second contact formed in said holding frame so as to be opposed to said first contact and electrically brought into contact with said first contact when the holding frame is positioned to be brought into a state where it is used, whereby the power from said dry cells is supplied to said illuminating means when said holding frame is positioned to be brought into a state where it is used.

Claim 13

The image observing auxiliary instrument according to claim 12, wherein the mounting portion of said mounting member is a recess portion which is provided in a position spaced apart from a portion, which supports said holding frame, of the mounting member by a predetermined distance and to and with which one end of said portable liquid crystal display apparatus in the vicinity of a portion containing the liquid crystal display is to be inserted and engaged,

Claim 14

An image observing auxiliary instrument used for a portable liquid crystal display apparatus or the like comprising a housing having an opening formed in a part of its surface and a liquid crystal display contained in the housing so as to be visually observed from the outside through the opening, which comprises: illuminating means for allowing a screen of the liquid crystal display to be made bright when an image reflected in said liquid crystal display is observed; a holding frame for fixedly holding said illuminating means; and a mounting member connected to said holding frame for allowing an upper position of said liquid crystal display to be irradiated by illuminating light from the illuminating means as well as detachably mounting said holding frame on the housing of said liquid crystal display apparatus.
