Abstract
Abstract In combination with an apparatus for counting sheet substances transferred in a row with any pitch of lapping, a partition plate for shutting rays having an edge touching the surfaces of the transferred substances and set in the direction of transference, a light source positioned at one side of said partition plate and a photoelectric converter positioned at the other side of said partition plate, so that rays filtering through the gap formed by the step at the lapping part of the transferred substances are sensed by said photoelectric converter which activates a counter.

In combination with an apparatus for counting sheet substances transferred in a row with any pitch of lapping, a partition plate for blocking rays having an edge touching the surfaces of the transferred substances and set in the direction of transference, a light source positioned at one side of said partition plate and a photoelectric converter positioned at the other side of said partition plate, whereby rays filtering from the gap formed by the step at the lapping part of the transferred substances and said plate are sensed by said photoelectric converter thereby activating a counter.
Claim 2
Dependent Claim

In combination with an apparatus for counting sheet substances transferred in a row with any pitch of lapping, a partition plate for blocking rays having an edge touching the surfaces of the transferred substances and set in the direction of transference, a light source positioned at one side of said partition plate and a photoelectric converter positioned at the other side of said partition plate, whereby rays filtering from the gap formed by the step at the lapping part of the transferred substances and said plate are sensed by said photoelectric converter thereby activating a counter.
Claim 3
Independent Claim
105 words
A method for counting sheet substances transferred in a row with any pitch of lapping by means of a light source and a photoelectric cell connected with a counter, which comprises the steps of: positioning a partition plate so as to lightly touch the surface of the substances being transferred; in the direction of transference positioning said light source on one side of said plate and said photoelectric cell on the other side of said plate, and then detecting with said photoelectric cell the light rays leaked from the gap between said plate and the upper surface of the lapped part of said transferred substance.
Claim 4
Independent Claim
