A motorcycle includes a rear arm, at one end of which a rear wheel is axially supported and the other end of which is pivotally supported by a body frame via a pivotally supporting shaft. The microfluidic device includes guides disposed along both edges, a lower plate including a flow path defined between the guides, and a movable upper plate moved along the guides on the lower plate and having a length less than that the flow path. Each attenuation stage comprises a simulcast signal generator for generating an error signal, and attenuation means which attenuate, in dependence of said first error signal, at least one of the analogue and the digital broadcast signal. In response to a content from one or more of the multiple sources changing at a source, the dynamic document is updated with updated content, and a version name of the dynamic document is updated to reflect the updated content. Security can be provided by way of a security application integrated with software of the ticker or by way of another security component with which the ticker software communicates. The information processing apparatus changes an image reading setting included in a profile identified based on the transmitted identification information of the image forming apparatus to the transmitted image reading setting, and transmits an image reading instruction based on the changed profile to the image forming apparatus.
