That is, in the vibration conveying apparatus 100, it is required to process the goods M so that the input amount and the discharge amount of the goods M are equal within a predetermined time. 100% processing is required. Therefore, the control signal generator 14 generates the first control signal based on the processing time obtained from the calculated input amount.
