Abstract: PURPOSE:To facilitate the manufacture of the subject apparatus, prevent the leakage of carbonated beverage easily and permit a reduction in its size by providing a stopper for controlling an open position of an actuating member to set the opening of a beverage passage, an operating shaft slidably retained by an adjusting screw in a predetermined direction and an energizing means for pressing the actuating member into a closed position. CONSTITUTION:When beverage is not being supplied, an energizing means 22 holds an operating shaft 17 against an actuating member 16, which, in turn, is pressed into a closed position to close a beverage passage 3. When the operating shaft 17 is moved by an operating lever 24 against the energizing means 22, the position maintaining pressure exerted on the actuating member 16 is released and, therefore, it is moved into an open position and stopped by engagement with a stopper 23. At this time, the open position of the actuating member 16 is unequivocally set by the stopper 23, independently of the movement length of the operating shaft 17. If an adjusting screw 21 is moved, the position in which the actuating member 16 is stopped by engagement with the stopper 23 moves, changing the open position thereof and, therefore, the opening of the beverage passage 3 can be adjusted by the adjusting screw 21.

IPC: G07D5/08
Filed: 1987-11-06
Abstract: PURPOSE: To easily perform deregulation within an allowable range by setting the allowable range through a variable resistor circuit and catching the allowable range with a central value and width. CONSTITUTION: A discriminator 6 detects the central value of the allowable range corresponding to the potential dividing value of an output voltage from a measuring sensor 2 due to a 1st variable resistor circuit 4 at standby time and detects the width of the allowable range corresponding to the potential dividing value due to a 2nd variable resistor circuit 5. When a coin is passed through a coin passage 1 and a measuring sensor 3 detects a coin characteristic value, the discriminator 6 discriminates whether the value of the coin characteristic signal is settled within the allowable range or not and discriminates whether this coin is proper or not. Thus, by setting the data of the allowable range to a volume circuit, the data can be easily set and changed.
