Patent ID: 7641037

Claim:
A bill handling apparatus, comprising: a line sensor disposed along a direction transverse to a bill feeding path, the line sensor being configured to read a bill fed on the bill feeding path; a sensor board configured to mount the line sensor on one face and a first connector on another face; a control board configured to mount a second connector, which is configured to connect to the first connector on the sensor board, on a flat face of the control board; and a side wall extending in a direction parallel to the bill feeding path, wherein a predetermined opening is formed on the side wall, the first and second connectors are comprised of stacking connectors configured to electrically connect the sensor board and the control board, and are mounted on the sensor board and the control board so as to be positioned in proximity to the opening of the side wall, when the sensor board and the control board are disposed inside the apparatus, a surface of the line sensor is exposed to the bill feeding path, when the sensor board is disposed at a predetermined position inside of the apparatus by being inserted via the opening of the side wall, the control board is electrically connected and opposed to the sensor board inside the apparatus while the first and second connectors connected to each other are sandwiched therebetween, when the second connector is connected to the first connector of the sensor board disposed inside of the apparatus; and the opening of the side wall, which is configured to receive the sensor board into the apparatus, is formed so that a connection state between the first connector of the sensor board disposed inside the apparatus and the second connector of the control board is externally visible through the opening.
