Abstract: Cost counting apparatus wherein at each transaction a printing drum prints a consumed amount that is pre-set into the apparatus, a calculating section subtracts that amount from a balance that is initially set into an electronic memory, an electromechanical display section displays the resulting balance after each transaction and the positions of the elements of the display are communicated for use in restoring the balance information to memory in the event of power failure.

Abstract: A gatherer comprises a generally cylindrical bin drum having circumferentially thereon a plurality of inclined shelves spaced apart each other for receiving papers. The gatherer further comprises a paper-size changing body and a switching means for the changing body. The gatherer thus constructed has a number of advantages, such as convenient and rapid introduction and discharge of the papers, accurate alignment of the papers, convenient and simple control of the introduction and the discharge of the papers through rotation direction of the bin drum and applicability to any paper size, as well as high performance with compact and simple construction and so forth.
