Abstract: Evidence of a discrimination result of a drug can be presented, and various marks can be dealt with. A computer includes a feature extraction unit and a discrimination unit. The feature extraction unit generates an extraction mark image in which a mark appearing on a captured image is extracted, based on an output value obtained by inputting the captured image of a target drug whose type is unidentified to a trained model constructed to extract the mark formed on the drug. The discrimination unit discriminates the type of the target drug, based on a collation result between the extraction mark image and a registration mark image registered in advance for each type of the drug.

Abstract: A rider operates a driving source switching lever to switch an operation mode to a normal traveling mode or an auxiliary moving mode. During the normal traveling mode, a motorcycle travels by a driving force generated by an engine. During the auxiliary moving mode, the motorcycle moves at a low speed by a driving force generated by a vehicle driving motor.

When the rider operates the forward-backward movement operator during the auxiliary moving mode to put the forward-backward movement operator in a backward movement instruction state, the vehicle driving motor is controlled such that the motorcycle moves backward.
