Abstract: A coin dispenser is disclosed to use a dialing rod of a dialing device of a coin dispensing unit to push one side of the peripheral edge of one metal coin so that the other side of the peripheral edge of the metal coin will push two coin-stopping columns of one spring plate of the coin dispensing unit, causing the two coin-stopping columns to slide along the peripheral edge of the metal coin, and thus, when the metal coin crosses two coin-stopping columns, the metal coin is sent out of the coin outlet, achieving the effect of dispensing one metal coin at one time.

Abstract: An ink-staining anti-theft cash box includes a cash box mounted in a host machine for receiving and storing bills, an ink-jet module and an anti-theft security device consisting of a gas cylinder, a needle valve unit, a drive unit and a trigger unit. When the trigger unit detects abnormal separation of the cash box from the host machine, the trigger unit is triggered, and the drive unit is activated to move the gas cylinder toward the needle valve unit from a first position to a second position where an air seal diaphragm of the gas cylinder is pierced by the needle valve unit, and the compressed gas of the gas cylinder is released through an ink tub into an ink cartridge to force an ink out of a nozzle assembly of the ink-jet module for staining storage bills in the box body, enhancing the security level of the cash box.
