Claim 0:
1. A combinatorial weighing device comprising:
a linear feeder that vibrationally transports an article from an upstream side to a downstream side in a direction of transport; and
a controller in charge of drive control of the linear feeder; and
an article detector that detects whether the article is currently present at a downstream end of a trough of the linear feeder in the direction of transport,
the controller being configured to change a vibration strength by which the linear feeder is driven to operate depending on whether the article detector is detecting the article at the downstream end of the trough, wherein
the linear feeder is supplied with the article from a retaining hopper that retains and discharges the article,
the linear feeder discharges the article at the downstream end of the trough into a supply hopper,
the controller sets, as the vibration strength by which the linear feeder is driven to operate when the article detector is detecting the article at the downstream end of the trough, a first vibration strength for discharge of the article into the supply hopper, and
the controller sets, as the vibration strength by which the linear feeder is driven to operate when the article detector is not detecting the article at the downstream end of the trough, a second vibration strength for transport of the article to the downstream end of the trough.
