To provide a power switch structure of an inter-stand machine for a game machine, which enables an operator to surely confirm that appropriate positioning is performed without operating the inter-stand machine at an inappropriate position.

The power switch structure comprises: a positioning confirmation means provided with a moving body to be moved by the arrangement of an adjacent game machine at an appropriate installation position, for detecting the movement of the moving body and confirming that the game machine and the inter-stand machine for the game machine are appropriately positioned; and a reporting means for reporting the confirmation of appropriate positioning by the positioning confirmation means. The positioning confirmation means turns the inter-stand machine for the game machine to a non-energized state by interrupting a power source circuit in the case of not detecting the appropriate movement of the moving body and turns the inter-stand machine for the game machine to an energized state by turning the power source circuit to a conductive state in the case of detecting the appropriate movement of the moving body.
