A medium storage box includes a guide member and a liquid spraying mechanism. The guide member forms a stacking space for a medium. The liquid spraying mechanism sprays a liquid from a liquid spraying nozzle. The liquid spraying nozzle has a pipe section through which liquid flows, a first liquid spray hole and a second liquid spray hole. The first liquid spray hole sprays liquid in a direction that intersects an extension direction of the pipe section at substantially a right angle. The second liquid spray hole sprays liquid in a direction that is approximately the extension direction of the pipe section.

Embodiments relate to a security system for securing items within any cavity, of any object, which may be opened or closed with a zipper. The security system includes functionality to detect the opening and/or detect the closing of a zipper. The security system may be configured to trigger an alarm if the zipper is opened while the security system is in an armed state. The security system may be configured to not trigger the alarm if the zipper is opened while the security system is in a disarmed state. The security system may be armed and/or disarmed via a wireless signal.
