Claim 5

An external display device for a camera comprising: (a) an electro-optical display panel consisting of one unit; (b) segments for digit display of at least four figures formed in said display panel; (c) means for forming a plurality of types of photographing information to be displayed by said digit display segments, said means having at least shutter time information, film sensitivity information and time counting information in bulb exposure mode; (d) selecting means for selecting one of the plurality of photographing information to be displayed by said digit display segments; and (e) display means for causing said digit display segments to display the selected one of the plurality of types of photographing information by said selecting means, whereby when said shutter time information and said film sensitivity information are selected, said display means renders all the figures of said digit display elements possible to display, while when said time counting information is selected, the least significant figure of said digit display segments is always rendered non-operative, and at least two of the other figures are rendered possible to display.

Claim 6

An external display device for a camera comprising: (a) an electro-optical display panel consisting of one unit; (b) segments for digit display of at least four figures formed in said display panel; (c) means for forming a plurality of types of photographing information to be displayed by said digit display segments, said means having at least shutter time information, film sensitivity information and time counting information in bulb exposure mode; (d) selecting means for selecting one of the plurality of photographing information to be displayed by said digit display segments; and (e) display means for causing said digit display segments to display the selected one of the plurality of types of photographing information by said selecting means, whereby when said shutter time information and said film sensitivity information are selected, said display means renders all the figures of said digit display elements possible to display, while when said time counting information is selected, the least significant figure of said digit display segments is always rendered non-operative, and at least two of the other figures are rendered possible to display.

Claim 7

A device according to claim 4, wherein said digit display segments consist of four figures, the most significant figure being made of fixed digit segments for "1", and the least significant figure being made of fixed digit segments for "0".

Claim 8

A device according to claim 1, further comprising film frame information included in said means for forming the plurality of types of photographing information.

Claim 9

A device according to claim 4, further comprising film frame information included in said means for forming the plurality of types of photographing information.

Claim 10

An external display device for a camera having a plurality of photographing modes, comprising: (a) photographing mode selecting means for selecting one of said plurality of photographing modes; (b) an electro-optical display unit; (c) a plurality of photographing mode display colored patterns of non-changeable patternized to depict said plurality of photographing modes, said display colored patterns being arranged in pictographic shapes, and said display colored patterns being arranged in said electro-optical display unit; (d) electro-optical display patterns responsive to electrical control for changing between light shuttering and light permeating states, said display patterns being in the area of said display colored patterns and being formed almost to the shapes of said display colored patterns, and said electro-optical display patterns being arranged in said electro-optical display unit; and (e) a display circuit arranged to operate at least one of said electro-optical display patterns according to the operation of said photographing mode selecting means.

Claim 11

An external display device for a camera having a plurality of photographing modes, comprising: (a) photographing mode selecting means for selecting one of said plurality of photographing modes; (b) an electro-optical display unit; (c) a plurality of photographing mode display colored patterns of non-changeable patternized to depict said plurality of photographing modes, said display colored patterns being arranged in pictographic shapes, and said display colored patterns being arranged in said electro-optical display unit; (d) electro-optical display patterns responsive to electrical control for changing between light shuttering and light permeating states, said display patterns being in the area of said display colored patterns and being formed almost to the shapes of said display colored patterns, and said electro-optical display patterns being arranged in said electro-optical display unit; and (e) a display circuit arranged to operate at least one of said electro-optical display patterns according to the operation of said photographing mode selecting means.
