In a method of discriminating a sheet of the present invention, a comparison and discrimination value becoming the reference of the comparison and discrimination of a printing pattern data is updated whenever the preceding sheet passes through a photodetector. Accordingly, the comparison and discrimination of the following sheet is performed based on the updated comparison and discrimination value, and is not affected by the variation in the sensitivity of the photodetector.

Method of discriminating sheet

Described is a counting apparatus for counting paper sheets settable when effecting a batch counting to a clear mode in which the count data obtained in the counting operation of each preceding batch of paper sheets are cleared for counting a new batch or to an add mode in which the count data for the current batch is added to the count data for the preceding batch or batches and the resulting sum of the count obtained until the current time is displayed.

Apparatus for counting paper sheets

An apparatus for counting the number of paper sheets is described in which a target number entered by an entry unit is stored in a target number memory and displayed in a target number display section, the count number supplied from a sensor and counter section since the time of start of counting is displayed in a count number display section and compared to said target number, and the counting number is discontinued in case of coincidence between said count number and the target number. According to the invention, the entry section has a batch key, a plus key and a minus key. A gross or an approximate number is entered by the batch key and incremented or decremented by the plus or minus key for adjustment of the gross number to the desired number. When the gross number is the infinite number, a continuous counting operation is performed until depletion of the paper sheets.
