Abstract: To provide a banknote-processing device with an IC card reader/writer function, a card reader/writer which records and reproduces information to and from the IC recording area of an IC card is fitted within the front mask where the banknote insertion slot is formed, or within a front mask cover which serves to cover this front mask.

Abstract: A coin dispensing apparatus having a simple construction and capable of dispensing coins securely and easily. A guide member is arranged extending along a tangent to a column formed in the center of rotation of the disk, whereby the coins can be smoothly transported along the guide member by means of a force from first protrusions without applying an impulsive force to the first protrusions and the guide member. Each coin transported to a predetermined position by the associated first protrusion is further transported to the outside of the transportation limit of the first protrusion by a second protrusion which is associated with a subsequent through hole, and is delivered securely to a coin dispensing port. A stirring rod having a rigid portion with an elliptic section and a rod with a circular section is fixed to the center of rotation of the disk, and the coins in a hopper are stirred by the protuberances on the outer peripheral surface of the rigid portion.

Abstract: A bill identification apparatus which is hardly subject to decision errors attributable to fluctuations of detected data caused by aging or partial soiling of bills. In identifying a bill, physical properties pi for various positions i on the bill are detected in synchronism with the transportation speed of the bill, a correction value pm for making an average value for an inspection section for the detected data pi equal to an average value for an inspection section for standard pattern values pci is obtained, and the detected data pi are corrected by using the correction value pm, thereby eliminating fluctuations of the data attributable to general deterioration or soiling of the bill or detectors.

Abstract: Various signals are exchanged between a coin acceptor section that identifies the authenticity of deposited coins and sorts out the on the basis of their denominations, and a change control section that receives the sorted-out coins and performs control to count the coins and to deliver the coins as a change. Such a signal exchange between the two sections is achieved through optical coupling between a light emitting diode and a photo transistor, without employing any electric contacts. Further, electric power supply from the change control section to the coin acceptor section is done through spring-biased probes without employing any electric connectors, or through inductive coupling without employing any electric contacts. Such arrangements can greatly facilitate attachment and detachment of the coin acceptor section to and from the change control section.

Abstract: An insulated gate field effect transistor having improved high-frequency operating characteristics includes an extended region electrically connected to one of the source and drain regions and spaced from the surface of the substrate. The extended region extends toward the other of the source and drain regions such that the distance between the source and drain regions is relatively small within the substrate and relatively large at the surface of the substrate.
