Abstract

Abstract A device for indicating characters by selective activation of plural segments is arranged along two vertically adjoining rectangles with a horizontal common side therebetween. The device comprises a first pair of segments and a second pair of segments. The first pair of segments includes an upper segment and a lower segment separated in the middle of the right-hand vertical side of the upper one of the rectangles. Each segment is so shaped as to at least partly lie along the right-hand vertical side of the upper rectangle. The second pair of segments includes an upper segment and a lower segment separated in the middle of the left-hand vertical side of the lower one of the rectangles. Each segment is so shaped as to at least partly lie along the left-hand vertical side of the lower rectangle.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 239 words
In a camera having a mode selector capable of selecting a plurality of exposure control modes including a shutter speed priority mode, an aperture priority mode, and a program mode, a device for distinguishing and indicating the selected mode, comprising: plural segments arranged along two vertically adjoining rectangles with a horizontal common side therebetween, said plural segments including a first pair of segments having an upper segment and a lower segment separated in the middle of the right-hand vertical side of the upper one of said rectangles and constituting the right-hand vertical side of said upper rectangle and a second pair of segments having an upper segment and a lower segment separated in the middle of the left-hand vertical side of the lower one of said rectangles and constituting the left-hand vertical side of said lower rectangle; and means for indicating a character S by driving said plural segments excluding said lower segment of said first pair of segments and said upper segment of said second pair of segments when said shutter speed priority mode is selected, indicating a character A by driving said plural segments excluding every segment corresponding to the lower horizontal side of said lower rectangle when said aperture priority mode is selected, and indicating a character P by driving said plural segments excluding every segment corresponding to the lower horizontal and the right-hand vertical sides of said lower rectangle when said program mode is selected.
Claim 2
Dependent Claim 239 words
In a camera having a mode selector capable of selecting a plurality of exposure control modes including a shutter speed priority mode, an aperture priority mode, and a program mode, a device for distinguishing and indicating the selected mode, comprising: plural segments arranged along two vertically adjoining rectangles with a horizontal common side therebetween, said plural segments including a first pair of segments having an upper segment and a lower segment separated in the middle of the right-hand vertical side of the upper one of said rectangles and constituting the right-hand vertical side of said upper rectangle and a second pair of segments having an upper segment and a lower segment separated in the middle of the left-hand vertical side of the lower one of said rectangles and constituting the left-hand vertical side of said lower rectangle; and means for indicating a character S by driving said plural segments excluding said lower segment of said first pair of segments and said upper segment of said second pair of segments when said shutter speed priority mode is selected, indicating a character A by driving said plural segments excluding every segment corresponding to the lower horizontal side of said lower rectangle when said aperture priority mode is selected, and indicating a character P by driving said plural segments excluding every segment corresponding to the lower horizontal and the right-hand vertical sides of said lower rectangle when said program mode is selected.
Claim 3
Dependent Claim 52 words
A device according to claim 1, wherein said plurality of exposure control modes includes a manual mode, and further comprising another segment disposed to the right of said rectangles and means for indicating a character M by driving said further segment together with segments at the right-hand vertical side of said rectangles.
Claim 4
Dependent Claim 45 words
A device according to claim 1, wherein said upper segment of said first pair of segments comprises a substantially C-shaped segment extending from the right-hand vertical side of said upper rectangle, through the upper horizontal side, the left-hand vertical side thereof, and said common side.
Claim 5
Dependent Claim 43 words
A device according to claim 3, wherein said lower segment of said second pair of segments comprises a substantially U-shaped segment extending from the left-hand vertical side of said lower rectangle, through the lower horizontal side thereof, to the right-hand vertical side thereof.
Claim 6
Independent Claim 174 words
A device for indicating characters, comprising: first character indicating means including plural segments arranged along two vertically adjoining rectangles with a horizontal common side therebetween, said plural segments including a first pair of segments having an upper segment and a lower segment separated in the middle of the right-hand vertical side of the upper one of said rectangles, each segment of said first pair being so shaped as to at least partly lie along the right-hand vertical side of said upper rectangle, and a second pair of segments having an upper segment and a lower segment separated in the middle of the left-hand vertical side of the lower one of said rectangles, each segment of the second pair being so shaped as to at least partly lie along the left-hand vertical side of said lower rectangle; and second character indicating means for indicating a character M, including at least one segment disposed along a left-hand vertical line of the character M which is common to the right-hand sides of said upper and lower rectangles.
Claim 7
Independent Claim 174 words
A device for indicating characters, comprising: first character indicating means including plural segments arranged along two vertically adjoining rectangles with a horizontal common side therebetween, said plural segments including a first pair of segments having an upper segment and a lower segment separated in the middle of the right-hand vertical side of the upper one of said rectangles, each segment of said first pair being so shaped as to at least partly lie along the right-hand vertical side of said upper rectangle, and a second pair of segments having an upper segment and a lower segment separated in the middle of the left-hand vertical side of the lower one of said rectangles, each segment of the second pair being so shaped as to at least partly lie along the left-hand vertical side of said lower rectangle; and second character indicating means for indicating a character M, including at least one segment disposed along a left-hand vertical line of the character M which is common to the right-hand sides of said upper and lower rectangles.
Claim 8
Dependent Claim 41 words
A character indicating device according to claim 5, further comprising means for indicating a character S by driving said plural segments excluding said lower segment of said first pair of segments and said upper segment of said second pair of segments.
Claim 9
Dependent Claim 47 words
A character indicating device according to claim 5, wherein said upper segment of said first pair of segments comprises a substantially C-shaped segment extending from the right-hand vertical side of said upper rectangle through the upper horizontal side, the left-hand vertical side thereof, and said common side.
Claim 10
Dependent Claim 45 words
A character indicating device according to claim 7, wherein said lower segment of said second pair of segments comprises a substantially U-shaped segment extending from the left-hand vertical side of said lower rectangle, through the lower horizontal side thereof, to the right-hand vertical side thereof.
