<P>PROBLEM TO BE SOLVED: To provide a game machine whose model change accompanying a change in an input operation can be done at low cost. Ž<P>SOLUTION: On the front surface frame 14 of a Pachinko game machine 10, a through port 14d is formed through to the front surface side of a game board 16 forming a game area, and a switch unit 120 is detachably attached at a position where the through port 14d is disposed. Thus, while two upper and lower buttons 121 and 122 are used for a game in the Pachinko game machine 10, by attaching a switch unit or the like to which only one button is mounted instead of the switch unit 120 to the front surface frame, the machine can be changed into the model requiring different input operations while sharing an inner frame 13 and the front surface frame 14. Thus, a plurality of kinds of the machine models having the different input operations can be manufactured at a low cost. Ž<P>COPYRIGHT: (C)2010,JPO&INPIT Ž
