Description

[Detailed Description of the Invention] [Industrial field of application] The present invention is a circuit board mounting device for a gaming machine that detachably holds a circuit board assembled with an IC (integrated circuit) and other circuit elements inside a gaming machine. Regarding

[Prior Art] In a gaming machine such as a slot machine controlled by an electronic circuit, an electronic circuit such as an IC that constitutes a control device for performing more complicated control is attached as the game content becomes more sophisticated or complicated. A circuit board is housed inside the gaming machine.

The applicant of the present invention has provided a circuit board mounting device capable of efficiently and safely mounting and removing the circuit board in a limited space inside the gaming machine when the circuit board is assembled. As disclosed in Japanese Utility Model Laid-Open No. 1-93790, it is a circuit board case that houses a circuit board and has a projecting portion on at least one end surface, and a terminal portion of the circuit board that receives and holds the case. A holding member having a connector to be electrically connected and a support member that rotatably supports the case by engaging a protruding portion of the case are provided, and the case is held by rotating the case with the support member as a fulcrum. It is detachable from the member.

[Problems to be solved by the invention] However, in a game machine incorporating such a circuit board mounting device, the circuit board may be mistakenly attached / detached while the power is on when parts are replaced or repaired. Therefore, there was a risk that the electronic circuit on the circuit board would be destroyed. In particular, if the circuit board is taken out while the power is on, the voltage of the power supply terminal on the connector side is applied to the input / output terminals other than the power supply terminal on the circuit board side due to movement or displacement of the circuit board. The electronic circuit is electrically destroyed, but in the game machine, even if it is not destroyed,
If a problem occurs in the electronic circuit and the game control is changed even a little, the interest of the player is spoiled, and the game machine becomes unpopular.

In view of the above, it is an object of the present invention to provide a circuit board mounting device suitable for a gaming machine by making it impossible to attach and detach the circuit board inside the gaming machine while the power is on. .

[Means for Solving the Problems] According to the present invention, a circuit board case for accommodating a circuit board and having a projecting portion on at least one end surface thereof, and receiving and holding the case and electrically connecting to a terminal portion of the circuit board are provided. A circuit board mounting device provided with a holding member having a connector, provided in a game crosspiece, in which a switch is interposed in a power supply circuit for supplying power from the connector to the circuit board and which is engageable with a protruding portion of the case. A stop member and a switch operating member that operates in conjunction with the locking member are provided, and the locking member engages the protruding portion when the case is attached to the holding member to fix the case to the holding member. Is configured so that the switch is turned on when the locking member engages with the protruding portion of the case, and is turned off when the locking member is disengaged from the protruding portion of the case.

The above-mentioned switch operating members may be separate members as long as they operate in conjunction with the locking member, but it is preferable to form both members integrally.

In addition, a supporting member is provided on both end surfaces of the case, the locking member is arranged so as to engage with one of the protruding portions, and the case is rotatably supported by engaging with the other of the protruding portions. Is preferably installed near the holding member.

[Operation] According to the present invention, when the case containing the circuit board is mounted on the holding member in the gaming machine, the terminal portion of the circuit board is electrically connected to the connector of the holding member. In this state, the case can be fixed to the holding member by engaging the locking member with the projecting portion of the case. Since the switch actuating member turns on the switch of the power supply circuit in conjunction with this engaging operation, the necessary voltage is supplied to the circuit board without separately operating the power supply switch. Here, even if the circuit board is taken out, the case is fixed to the holding member by the locking member, so that the circuit board and the power supply are not inadvertently disconnected while the power is still on.

When the case is detached from the holding member, the engagement of the locking member with the projecting portion of the case may be released. In conjunction with this disengagement, the switch operating member turns off the switch of the power circuit, so that the circuit board can be safely removed with the power turned off without operating the power switch separately in this case as well. .

In this way, it is possible to prevent the electronic circuit from being damaged or adversely affecting the game control operation caused by the attachment / detachment of the circuit board while the power is on.

In the gaming machine circuit board mounting device of the present invention, when the case is provided with the protruding portions on both end surfaces, one of the protruding portions is used for engagement with the locking member to prevent the circuit from being damaged. When the case is attached or detached, the work efficiency is also improved by engaging the other protrusion with the support member and rotating the case.
