PROBLEM TO BE SOLVED: To suppress the reduction in combination accuracy and the reduction in operation speed by re-input or the like of a measuring object, by decreasing the frequency of occurrence of an empty measuring hopper that cannot contribute to a combination calculation.SOLUTION: By vibrating a linear feeder pan 6, a measuring object 20 is conveyed from a conveyance end 6a and is discharged and supplied to a supply hopper 12. Then, when a next measuring object 20 does not exist at the conveyance end 6a of the linear feeder pan 6, the next measuring object 20 is moved to the conveyance end 6a in a short time. Therefore, the vibration strength of a linear feeder 8 is made greater than a normal vibration strength. |
