Abstract
Abstract A document size detection device detects the size of documents (N) such as non-US currency and comprises a housing (33), a plate (35) mounted in the housing past which each document is moved, and LED photoelectric sensors (37,38) positioned along and across the plate (35) for sensing the size of each document and for initiating a signal indicating the length and width of each document. The signals are transmitted to a counting machine, which counts the sheets in response to said signal, and thereby counts the value of the sheets where the latter are currency notes.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
57 words
A document size detection device for detecting the size of documents such as non-US currency comprising: a plate (35) past which the documents (N) are moved, and sensor means (37,38) positioned along the plate for sensing the length and width of each document and for initiating a signal indicating the length and width of each document (N).
Claim 2
Dependent Claim
44 words
A document size detection device according to claim 1, wherein the sensor means includes a plurality of LED sensor pairs (37,38) spaced in a pattern at the plate such that a different designated number of sensor pairs corresponds to different designated sizes of documents.
Claim 3
Dependent Claim
53 words
A device according to claim 3, in which a first set of sensor pairs (37,38) extends in a first direction of the plate for sensing the length of each document and a second set of sensor pairs (37,38) for sensing document width extends in a second direction substantially perpendicular to the first direction.
Claim 4
Dependent Claim
39 words
A detection device according to claim 3, in which the sensor means further comprising a detector (37a,38a), which is spaced apart from the width sensor pairs in said second direction, for detecting the trailing edge of each document N.
Claim 5
Dependent Claim
24 words
A document size detection device according to any of claims 1 to 4, further including means (41,43) for conveying each document over the plate.
Claim 6
Dependent Claim
45 words
A machine for counting money in the form of paper currency notes of different sizes as to width and/or length, comprising a document size detecting device according to claim 5, and counting means responsive to the said signal and connected to receive the said signal.
Claim 7
Dependent Claim
21 words
A machine according to claim 6, characterized by sorting means responsive to the said signal for sorting the sheets by size.
Claim 8
Independent Claim
75 words
A method of detecting the size of documents like sheets of paper currency comprising the steps of: sensing the presence of each sheet, identifying the sheet by sensing the width and length of the sheet, creating an electrical signal proportionate to the width and length of the sheet, transmitting the signal to a counting machine, counting the sheets in response to said signal, and counting the value of the sheets in response to the signal.
Claim 9
Dependent Claim
31 words
A method according to claim 8, further including the step of stopping the process when counting sheets of uniform size and a sheet of different size passes through the sensing unit.
Claim 10
Dependent Claim
40 words
The method of claim 8, further including the step of: transmitting a signal to a sorter corresponding to the size of each sheet being identified, and sorting the sheets by size in response to each signal sent to the sorter.
