Paper sheet processing device

A paper sheet processing apparatus comprising:

• a stand;
• a main body disposed on the stand and including
• a paper sheet insertion slot formed in a front side of the main body,
• and
• a paper sheet conveyance mechanism that conveys a paper sheet inserted from the paper sheet insertion slot;
• a magnetic sensing unit comprising a plurality of magnetic sensors;
• a controller;
• and
• a housing that stores the paper sheet conveyed by the paper sheet conveyance mechanism, the housing slidably mountable to the stand and demountable from the stand along a sliding direction, the housing including a placing plate on which the paper sheet is to be stacked and a spring that pushes the placing plate,
• wherein the paper sheet conveyance mechanism conveys the paper sheet to a feed port of the housing by discharging the paper sheet along a paper sheet traveling route that is extended from the paper sheet insertion slot toward inside of the main body and is formed to be bent at a back side of the main body so as to be inclined downward,
• wherein the apparatus further comprises:
• a reader that reads information on a paper sheet inserted into the paper sheet insertion slot, the reader disposed on the main body;
• a transmitter that sends the information read by the reader, the transmitter disposed on a lower surface side of the main body,
• wherein the housing comprises an antenna that receives the information wirelessly from the transmitter, is installed on an upper wall of the housing, and has a surface substantially parallel to the upper wall and facing the transmitter;
• and
• wherein the transmitter has a first surface substantially parallel to the surface of the antenna and a second surface substantially perpendicular to the surface of the antenna, the first surface broader than the second surface,
• wherein the stand is frame-shaped by being surrounded by a pair of side plates facing each other, a bottom plate, and a back plate, the bottom plate and the back plate are sandwiched by the pair of side plates, and the housing is inserted into the frame of the stand so that the housing and the stand pass each other, and
• wherein when the housing is completely mounted on the stand, an outer periphery of the housing is held by the side plates, the back plate and the bottom plate of the stand so that a positional relationship of the transmitter and the antenna is defined to allow the antenna to receive the information from the transmitter,
• wherein the main body comprises a wall,
• wherein the first surface of the transmitter is disposed on the wall of the main body,
• wherein the upper wall of the housing is substantially parallel to a ceiling plate of the stand during the sliding of the housing into the stand such that the first surface of the transmitter and the surface of the antenna are substantially parallel to each other,
• wherein the upper wall of the housing is spaced apart from the ceiling plate of the stand and the first surface of the transmitter partly faces the surface of the antenna such that a distance between the transmitter and the antenna is maintained to allow a communication between the transmitter and the antenna to be performed when the housing is incompletely mounted to the stand by the sliding,
• wherein when the housing is incompletely mounted, a lower wall of the housing is partly overlapped with the bottom plate of the stand, and
• wherein each of the plurality of magnetic sensors are disposed at different respective predetermined positions along the pushing direction of the spring, each of the plurality of magnetic sensors detecting a magnetic field when the placing plate reaches each respective predetermined position,
• wherein the controller:
• transmits the information stored in the storage to a server;
• counts a number of paper sheets that are stacked in the housing after a respective magnetic sensor detects the magnetic field,
• informs to an external device that the housing is approaching a full state after a respective magnetic sensor detects the magnetic field and before the counted number exceeds a first threshold, and
• stops storing the paper sheet into the housing when the counted number reaches a second threshold greater than the first threshold.
