The purpose of this research is to explore the mechanism design of gift machines and change machines, develop a new type of electronic game machine, and improve the mechanisms of the old type of change machine. The Super Cup Gift Machine is a newly developed electronic game machine with a novel control mechanism that uses a Fire Electric Pen to negotiate a path, giving players different experiences. The machine’s exterior is covered with sheet metal, which not only improves its stability and robustness, but also reduces its cost. The game machine operates using three mechanisms. Firstly, a timing belt pulley and belt driven by a motor driver allows left and right transverse sensors to move in the X direction. Secondly, movement in the Y direction is achieved with a guide bar and a linear bearing with a hoisting appliance. Finally, the reciprocating action in the Z direction is achieved using a slider crank mechanism. The inside of the old type of change machine, which converts coins into tokens, can only store 2000 tokens. In order to increase the storage capacity to 20,000, we first used SOLIDWORKS drawing software to change the existing 3D stereogram; its internal redundant space was put to use, and a coin hopper able to bear the weight of 20,000 tokens with a weight sensor was designed. Meanwhile, two inclined planes and an automatic coin-dropping device were added in the coin hopper to prevent multiple coins from dropping at one time and crushing the automatic coin-dropping device. Finally, finite element analysis of the developed structure was performed using ANSYS software, and a physical machine was made by assembling the parts. The designs were tested several times to prove the feasibility of the structure.
