money gun

A gun-shaped novelty device designed to shoot out paper money. Also called a cash cannon. A common version of the device is a boxy gun-shaped device where a stack of bills are loaded into the top and its lid helps to hold down the stack of bills. With the pull of the trigger a wheel inside touching the lowest bill in the stack will rapidly spin and propel the bill through the slot in the front. It can readily be used to make falling money.

Money guns appear as a weapon used in Osaka in the series Kill la Kill.
