<p>PROBLEM TO BE SOLVED: To provide a game machine for improving the smoothness of an opening operation of a back surface block from a front surface block and for improving the durability of a locking mechanism for locking the back surface block on the front surface block.SOLUTION: A game machine is constructed to comprise: a biasing mechanism for biasing a front surface block and a back surface block in their opening direction while the back surface block being locked with respect to the front surface block; and an automatic opening restricting mechanism for restricting such an automatic opening of the back surface block from the front surface block due to the biasing force from the biasing mechanism which accompanies the opening of the back surface block with respect to the front surface block in response to a predetermined operation upon a common operation portion of a locking mechanism while the game machine body being in an open state with respect to a frame body. The automatic opening of the back surface block with respect to the front surface block as accompanying the opening of the inter-block locking portion is stopped within a predetermined intermediate open range at an intermediate unlocked state, in which the back surface block can be unlocked and locked without being accompanied by an operation upon the common operation part.</p> |
