Abstract
Abstract A digital display body-weight meter includes a positioning means to bring a code disc having a logic code arrangement to standstill at the termination of its rotation according to the descent of a footstool such that a detecting means to detect a logic code is located at the center of one of a plurality of logic codes, whereby reliable measurement signal may be obtained from the detecting means. It also includes means to bring the detecting means into contact with the logic code arrangement on the code disc after the termination of the rotation of the disc, whereby wear of brush and conductor can be eliminated and also good contact therebetween and reliable read-out of signal may be ensured.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
112 words
A digital display body-weight meter comprising a footstool, a code disc having a circumferential logi code arrangement of a plurality of electrical conductor codes and adapted to be rotated according to the extent of descent of said footstool that results when a body to be measured rides thereon, a detecting means to detect at least one electrical conductor code corresponding to the descent of the footstool, a positioning means to bring the code disc to standstill at the termination of its rotation such that said detecting means is located at the center of one of said electrical conductor codes, and a display section for digitally displaying the output of said detecting means.
Claim 2
Dependent Claim
112 words
A digital display body-weight meter comprising a footstool, a code disc having a circumferential logi code arrangement of a plurality of electrical conductor codes and adapted to be rotated according to the extent of descent of said footstool that results when a body to be measured rides thereon, a detecting means to detect at least one electrical conductor code corresponding to the descent of the footstool, a positioning means to bring the code disc to standstill at the termination of its rotation such that said detecting means is located at the center of one of said electrical conductor codes, and a display section for digitally displaying the output of said detecting means.
Claim 3
Dependent Claim
24 words
A digital display body-weight meter according to claim 1, wherein said code disc also has a grounding conductor concentric with said logic code arrangement.
Claim 4
Dependent Claim
72 words
A digital display body-weight meter according to claim 1, wherein said detecting means comprises at least one brush caPable of being brought into contact with said electrical conductor codes, a rotatable brush support supporting one end of said brush and a rotary solenoid means co-operating with a rotative shaft of said brush support, said brush being brought into contact with said electrical conductor codes only when said rotary solenoid means is energized.
Claim 5
Dependent Claim
81 words
A digital display body-weight meter according to claim 1, wherein said detecting means comprises at least one brush capable of being brought into contact with said electrical conductor codes, a brush support supporting one end of said brush, a cam member rotatable and capable of urging said brush and a rotaty solenoid means co-operating with said cam member, said brush being urged by said cam member into contact with said electrical conductor codes only when said rotary solenoid means is energized.
Claim 6
Dependent Claim
59 words
A digital display body-weight meter according to claim 1, wherein said positioning means comprises a plurality of magnetic material spaced along the circumference of said code disc and individually located adjacent respective conductor codes between adjacent borderlines between adjacent conductor codes and at least one magnet held at a fixed position and capable of facing said magnetic material pieces.
Claim 7
Dependent Claim
56 words
A digital display body-weight meter according to claim 1, wherein said positioning means comprises a plurality of recesses individually formed in said code disc adjacent respective conductor codes between adjacent borderlines between adjacent conductor codes and at least one positioning member capable of facing said recesses and adapted to be urged into engagement in said recesses.
Claim 8
Dependent Claim
31 words
A digital display body-weight meter according to claim 6, wherein said at least one positioning member is provided with a rolling member capable of being in rolling contact with said recesses.
