Claims

[Scope of utility model registration request]

an ejector die that is supported from above and presses the coin and makes the pressed coin stick out; a male die that moves up and down to press the coin from below; a table whose upper surface is positioned at the lowest point of the range; a feeding device provided on the table to transfer the coin material onto the male die; and a feeding device positioned below the male die to support the vertical movement of the male die. A push rod provided integrally with this, a toggle transmission device that connects the lower end of the push rod to the fixed side of the main body and pushes the male die upward through the push rod, and a toggle transmission device that connects the lower end of the push rod to the fixed side of the main body and pushes the male die upward, and the male die is positioned at the top surface of the table and the highest point during pressing. A cam whose outer periphery is formed so as to move up and down accurately, smoothly and continuously between positions, and which is directly attached to the toggle transmission to directly drive the cam; A press machine for producing coins, comprising a counterbalance for biasing the toggle transmission device toward the cam side so that the toggle transmission device can follow the cam.
