Abstract: The portable memory medium of the invention has a memory, for storing the predetermined information which is embossed on its surface, and a CPU. When a read instruction is supplied from a portable memory medium handling system externally connected to the portable memory medium, the CPU reads out the predetermined information stored in the memory, and supplies it to the portable memory medium handling system, which then displays the information on a display unit. The operator compares the information displayed on the display unit with the predetermined information embossed on the portable memory medium, and thereby determines the authenticity of the embossed predetermined information.

Abstract: A sheet convey apparatus which conveys a mixture of obverse and reverse-sheets set at an inlet port to a collecting section, comprises a first convey path for conveying obverse-presented bills which are distinguished from reverse-presented bills by a sorting convey path, and a second convey path disposed parallel to the first convey path, for conveying reverse-presented bills which are to be reversed.

Abstract: A sheet collecting apparatus for collecting paper sheets, comprises a plurality of collecting chambers which are arranged to receive sorted bills through an insertion port, a shutter unit which is disposed to cover dispensing ports of all of the collecting chambers and is movable between a first position where all of the dispensing ports are closed and a second position where all of the dispensing ports are opened, and a drive section for driving the shutter unit in one of the first and second positions. The paper sheets are stacked in the collecting chamber when the shutter unit is located in the first position and the paper sheets are dispensed outside the collecting chamber when the shutter unit is located in the second position.
