Fare box in which belt conveyors transport coins and dollar bills past an inspection window to a vault. The coins are sized, indicated audibly, and registered. Both sides of dollar bills may be inspected by transillumination or by automatic reversal of the bills in transit. The coin size detector comprises a multiple-contact switch employing an actuator arm driven in a first direction by the coins and in the opposite direction by a spring, the length of the stroke of the actuator arm in the first direction determining which contacts are transferred when the arm moves in the reverse direction.
