Claim 0:
1. A combination weighing device, comprising:
at least two linear feeders including an upstream linear feeder and a downstream linear feeder, the linear feeders being disposed to transport an article from an upstream side to a downstream side in a direction of transport;
a controller in charge of drive controls of the linear feeders; and
an upstream article detector that detects the article currently present at an upstream end of a trough of the downstream linear feeder in the direction of transport,
the controller being configured to, when the upstream article detector is not detecting the article, drive the upstream linear feeder to operate until the article is detected by the upstream article detector,
the controller being configured to, when a predetermined period of time is passed after the upstream linear feeder starts to be driven, drive the upstream linear feeder to operate by an increased vibration strength.
