Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
92 words
A display device for use in association with an electronic balance, the display device comprising: a digital display section for digital-displaying a measured value of a load applied to a scale pan of the balance; an analog display section for analog-displaying a value corresponding to a number of digits selected from the digits displayed on said digital display section, said analog display section including a plurality of display elements arranged in series; a selection switch for selecting said number of digits; and means for indicating the digits selected by said selection switch.
Claim 2
Dependent Claim
92 words
A display device for use in association with an electronic balance, the display device comprising: a digital display section for digital-displaying a measured value of a load applied to a scale pan of the balance; an analog display section for analog-displaying a value corresponding to a number of digits selected from the digits displayed on said digital display section, said analog display section including a plurality of display elements arranged in series; a selection switch for selecting said number of digits; and means for indicating the digits selected by said selection switch.
Claim 3
Dependent Claim
28 words
A display device as set forth in claim 1, wherein said series of display elements are arranged in more than two straight lines, thereby allowing a bar-shaped representation.
Claim 4
Dependent Claim
33 words
A display device as set forth in claim 1, wherein said analog representation is carried out in correspondence to the digits automatically selected in response to the changing speeds of the measured values.
Claim 5
Dependent Claim
34 words
A display device as set forth in claim 1, wherein said analog representation is carried out only when the corresponding digits in said digital representation change at a slower speed than a predetermined speed.
Claim 6
Dependent Claim
25 words
A display device as set forth in claim 1, wherein said series of display elements are arranged in a loop, thereby allowing a loop-shaped representation.
Claim 7
Dependent Claim
25 words
A display device as set forth in claim 5, wherein said display elements arranged in a loop surround said first display section for digital representation.
