Abstract
In a prepayment fluid feeder, a depressing member forces down a valve driving member through a coin located in a coin interposing space by an operation of a handle. When the driving member is depressed, a valve member is shifted to an open position, and a fluid such as tap water is supplied through a flow pipe. The driving member is locked by a locking mechanism in a position to which the member is depressed. A releasing mechanism acts on the locking mechanism and releases the locking of the driving member when the supply of a predetermined flow quantity is completed with a single coin, and the valve member is returned to the closed position, thereby stopping the supply of the fluid. The releasing mechanism comprises a setting wheel with notches formed on the outer periphery thereof and balls placed in the notches.
