Rapid lateral flow immunoassays have an extensive history of use in both the clinical and home settings. The pressure level of the secondary pulley is hereby raised and the transmission ratio of the CVT is changed in accordance with a predeterminable transmission ratio change and a predeterminable gradient. The calibration circuit executes calibration, using the calculation results. Thus, according to the present invention, information on an object can be reported to another object located at a remote position with a higher degree of reliability. If the information regarding the defective conveyance received from the engine controller 21 is information showing the occurrence of a feed delay jam, the image controller 23 transmits a jam clear command to cancel the feed delay jam to the engine controller 21.
