Abstract
Abstract A weighing machine with a digital display including a converter which responds to the body weight and generates digital signals, and electrical circuits which respond to the digital signals and generate signals actuating a display tube only when receiving a specific digital signal from the converter whereby a high stability is attained in the indication of the display.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
144 words
A weighing machine with a digital display comprising: a disc means having a rotation in accordance with the descending movement of a weighing platform, said disc means having a first mark pattern generating digital signal corresponding to the amount of said disc rotation and a second mark pattern generating timing signals in relation to said first mark pattern, those marks being shifted in circumferential position relative to each other; memory means in which said digital signal is not stored therein until said memory means receives said timing signal; said disc means having at least a first group and a second group, each group comprising said first and second marks, said first group representing the first order while said second group representing the second order; and a display means to display figures representing the weight measured in response to the output from said memory means.
Claim 2
Dependent Claim
144 words
A weighing machine with a digital display comprising: a disc means having a rotation in accordance with the descending movement of a weighing platform, said disc means having a first mark pattern generating digital signal corresponding to the amount of said disc rotation and a second mark pattern generating timing signals in relation to said first mark pattern, those marks being shifted in circumferential position relative to each other; memory means in which said digital signal is not stored therein until said memory means receives said timing signal; said disc means having at least a first group and a second group, each group comprising said first and second marks, said first group representing the first order while said second group representing the second order; and a display means to display figures representing the weight measured in response to the output from said memory means.
Claim 3
Dependent Claim
39 words
A weighing machine in accordance with claim 1, in which said memory circuit is comprised of a plurality of flip-flops, each of which is provided with a gate being enabled by coincidence of said digital and said timing signals.
Claim 4
Dependent Claim
23 words
A weighing machine as claimed in claim 1 in which said first mark is arranged in decimal digits in the 8-4-2-1 binary code.
Claim 5
Dependent Claim
29 words
A weighing machine as claimed in claim 1 in which said first group of marks is disposed nearer to the peripheral portion of said disc than the second group.
Claim 6
Dependent Claim
29 words
A weighing machine as claimed in claim 1 in which said second mark of said first group is disposed on the portion nearest to the circumference of said disc.
Claim 7
Dependent Claim
18 words
A weighing machine as claimed in claim 1 in which said first and second marks are slits respectively.
Claim 8
Dependent Claim
17 words
A weighing machine as claimed in claim 3, in which said flipflop is of a latch type.
Claim 9
Dependent Claim
140 words
A weighing machine with a digital display comprising: a disc means having a rotation in accordance with the descending movement of a weighing platform, said disc having plural digit annular areas encoded for respective digit orders of a multidigit number each annular area having at least one first mark generating digital signal corresponding to the amount of said disc rotation and at least one second mark generating timing signal in relation to said first mark, those marks being shifted in circumferential position relative to each other; memory means in which said digital signal is not stored therein until said memory means receives said timing signal; a display means to display figures representing the weight measured in response to the output from said memory means; and switching means automatically to close the power supply circuit therein when weighing operation is made.
Claim 10
Dependent Claim
140 words
A weighing machine with a digital display comprising: a disc means having a rotation in accordance with the descending movement of a weighing platform, said disc having plural digit annular areas encoded for respective digit orders of a multidigit number each annular area having at least one first mark generating digital signal corresponding to the amount of said disc rotation and at least one second mark generating timing signal in relation to said first mark, those marks being shifted in circumferential position relative to each other; memory means in which said digital signal is not stored therein until said memory means receives said timing signal; a display means to display figures representing the weight measured in response to the output from said memory means; and switching means automatically to close the power supply circuit therein when weighing operation is made.
Claim 11
Dependent Claim
45 words
A weighing machine with a digital display as claimed in claim 8, and including a manual switch connected in circuit with a d.c. power source and an a.c. power source selectively operable to energize the weighing and display circuits from either of said power sources.
