Abstract
Abstract 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.
