Sheet counting apparatus
First Claim
1. In a sheet counting apparatus, the combination comprising:
- a. a casing in which a stack of sheets to be counted is placed on one of their edges;
b. a sheet stand on the top of said casing, said sheet stand including means for exerting a forward pressure on the sheet-stack;
c. infeed means arranged forwardly of said sheet stand, said infeed means including at least one infeed roll which is rotatably mounted adjacent to one edge of the sheets in said sheet stand for frictionally and successively feeding out the foremost one of the sheets of a stack away from said sheet stand;
d. counting means arranged adjacent to said sheet stand for counting number of sheets successively fed from said sheet stand by said infeed means, said counting means including1. at least one sensing roll rotatably mounted under said infeed roll so as to be displaceable away from said infeed roll in response to travelling of each sheet between said infeed roll and said sensing roll,2. an arm on which said sensing roll is mounted, said arm being pivotally supported at one end thereof so as to be swingable through an angle corresponding to the degree of displacement of said sensing roll, and3. a counter switch mounted on the other end of said arm, said counter switch being adapted to be actuated each time when a single sheet travels over the sensing roll;
e. conveyor means having a rear end disposed adjacent to said infeed means and a front end being remote from said infeed means, whereby the successively counted sheets loaded on said conveyor means at said rear end are transported to said front end thereof;
f. recovery means for recovering the counted and transported sheets from said conveyor means in the form of a substantially neat stack, said recovery means including

Abstract
A neat arrangement such as a pack of bills or like sheets to be counted is placed on one of their longitudinal edges in a sheet stand formed on the top of the casing of a sheet counting apparatus. An infeed mechanism comprising first and second infeed rolls frictionally feed the sheets one by one into the apparatus. A pair of sensing rolls are mounted under the second infeed rolls for sensing the passage thereover of each sheet thus fed into the apparatus and hence for actuating a counter switch. The thus counted sheets are successively loaded on a conveyor mechanism at one end thereof and are thereby transported toward the other end, where the successive counted sheets are stacked for recovery purposes. The apparatus further comprises an adjusting mechanism for adjusting the position of the sheets in the sheet stand and in the recovery mechanism according to their size and a stop motion mechanism for instantly terminating the infeeding operation of the sheets.
