The present invention includes a memory configured to store data having a pinned layer and a plurality of stacked memory locations. During a state of the display displaying a designated image, upon detecting that a specific location in the image has been touched with the touch panel, the controller detects a velocity by which a touch position changes and a direction in which the touch position changes while the touch continues, and determines an input instruction. The kit can be releasably engaged to a second canister, without tools, with the second canister containing a second banner with a different ad andor message to thus facilitate changing banners.
