Abstract: A crane game machine which includes a premium article placing face for putting a large number of premium articles thereon, a crane having a plurality of hooks for grasping a premium article, and a driving mechanism for setting the crane to a position on the premium article placing face and for making the crane hooks grasp a premium article in response to a starting operation by an operator. A grasping force is changed by changing the weight of the crane. The probability of gaining the premium article can be regulated in a recreation hall or the like where the game machine is handled by varying the weight of the crane.

Abstract: A ball-shooting game machine having a starter hole for initiating a separate game when a game ball shot onto a game board enters into the starter hole, and a separate game device for conducting the separate game, is provided with a random number generator to produce a random number when a predetermined number of balls is shot onto the game board and the results of any separate game is determined by the value of the random number generated.

Abstract: A coin inlet in which a storing recess capable of accommodating a plurality of coins in the state of being piled up is disposed parallel to a slot for inserting coins one by one so as to move the coins accommodated in the storing recess to the slot.

Abstract: A circuit board mounting apparatus comprising a circuit board case with a circuit board, a circuit board holding member with a connector and a supporting member, wherein the circuit board case has at least one extending portion capable of rotatably engaging with the supporting member so that the circuit board of the case can be easily attached to or detached from the connector of the circuit board holding member. The circuit board can efficiently and safely be installed or taken off in a limited mounting space in an electronic equipment. Also, since the case accommodating the circuit board is attached or detached, the circuit board is prevented from damage by carelessness during operation.

Abstract: A coin dispenser which includes a coin accommodating bucket having an opening formed at the bottom, a rotary disc disposed under the bucket so as to be rotated substantially horizontally for moving coins, which are supplied from the bucket through the opening, outside by a centrifugal force, a guide for receiving the fringes of the coins moved outside due to the rotation of the rotary disc and for inducing the coins to an outlet, a regulating board for receiving the coins in the bucket above the opening, and an elastic stirring member having a non-circular cross section which is rotated together with the rotary disc in the opening of the bottom of the bucket. The elastic member collides with the coins and flips them so that the coins are stirred, thus preventing the clogging of coins.
