Abstract

In accordance with an output signal from a weight sensor mounted on a vehicle, a display control section causes a display unit to display weights calculated at predetermined intervals by a weight calculating section. The display control section adds, to the weight which is being displayed, the difference in the weights sequentially calculated by the weight calculating section from detection of start of a loading/unloading operation performed by a detection section to start of running of the vehicle and causes the display unit to display the obtained weight. When a release detection section has detected release of the brake within a predetermined time from the stoppage of the vehicle, detection of start of a loading/unloading operation is inhibited for a predetermined time from detection of the release. If release of the brake is not detected within a predetermined time from the moment at which the vehicle has been brought to the stoppage state, detection of start of a loading/unloading operation is enabled after a predetermined time elapses from the stoppage of the vehicle.
