Paper sheet processing device

A paper sheet processing apparatus comprising:

• a stand;
• a main body comprising a conveyer that conveys a paper sheet, the main body mountable and demountable from the stand;
• a housing that stores the paper sheet from the conveyer, the housing mountable and demountable from the stand;
• a transmitter that is disposed on the main body and sends wirelessly information of the paper sheet;
• and
• a controller,
• wherein the housing comprises:
• an antenna that receives wirelessly the information from the transmitter and is installed on an upper wall of the housing;
• a storage that stores the information of the paper sheet received through the antenna;
• a first plate on which the paper sheet is to be stacked;
• a second plate;
• and
• a pair of regulatory members disposed on both sides of the first plate,
• wherein when detecting insertion of the paper sheet in a state that the second plate is brought between the pair of regulatory members, the controller moves the second plate to form an opening between the pair of regulatory members such that the paper sheet passes through the opening, and
• wherein in the state that the second plate is brought at between the pair of regulatory members, the second plate is brought between the pair of regulatory members such that the opening through which the paper sheet passes is occluded,
• wherein the apparatus further comprises:
• a magnet that is disposed on the first plate and generates a magnetic field when a number of paper sheets stacked in the housing reaches a threshold value;
• and
• a magnetic sensor that is disposed on the main body and receives the magnetic field,
• wherein the controller:
• starts counting a number of paper sheets that are stacked in the housing after the magnetic sensor receives the magnetic field, and
• stops storing the paper sheet into the housing when the counted number is ten or more, and
• wherein the antenna includes a loop antenna having a loop surface such that a communication direction of the antenna is perpendicular to the loop surface,
• wherein the transmitter has a first surface substantially parallel to the loop surface and broader than a second surface perpendicular to the loop surface,
• wherein the housing is slidably mounted and demounted on the stand,
• wherein an upper wall of the housing is parallel to an opposing surface side of the stand during the sliding of the housing into the stand such that the loop surface and the first surface of the transmitter are substantially parallel to each other,
• wherein the first surface of the transmitter and the loop surface of the antenna are located substantially parallel to a direction of the movement of the housing when mounting and demounting,
• wherein the loop surface is positioned such that the antenna receives the information from the transmitter even when the housing is not located at a predetermined position after the housing is mounted on the frame,
• wherein the loop surface of the antenna and the first surface of the transmitter entirely overlap each other when the housing is located at the predetermined position, and
• wherein the upper wall of the housing entirely overlaps the first surface of the transmitter when the housing is at the predetermined position.
