PROBLEM TO BE SOLVED: To use the can by identifying the can generated thereat only from the other can while limiting a place for installation to a school, etc., and taking all the cans generated at the place for an object of deposits. SOLUTION: A device is provided with a charging mouth opening/closing body 5, which is arranged openable/closable at a charging mouth 4 of a device main body 1 and sends a can into a device main body, a compression mechanism 16 to compress a charged empty can, a box to recover a compressed can, metal sensors S1a, S1b to detect a can material received by the changing mouth opening/closing body, a shape sensor S2 to detect a can shape, a control circuit 102 to identify that a sent-in empty can is the can when the respective information from the metal and shape sensors are received, the material of the empty can detected by the metal sensor is metal and the shape of the empty can detected by the shape sensor is a fixed size and shape, and a hard coin refund mechanism operated by the signal from the control circuit.
