PURPOSE:To count the number of parts always precisely by setting a gate means to parts feeding state and supplying parts to be counted from a parts feeding device to a scale of a balance body. CONSTITUTION:A hopper 8 serving as a parts feeding device is arranged on the upper parts of the counting balance body 1 and the parts feeding port is opened/ closed by a gate 9. If the number of parts is to be set to n=124, the number is set in the balance body 1 by depressing ten keys and a limitation number setting button B. When a start button is depressed, a gate open starting signal is supplied from an output line A to the gate 9 to open the gate 9. When the number of parts reaches 124, the gate 9 is closed. Thus, the number of parts can be counted up always precisely. |
