Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a slot machine provided with a housing and a front door for opening and closing a front opening of the housing, and more particularly, to a technique for facilitating replacement of old and new models.
[0002]
[Prior art]
Conventionally, as a slot machine that has facilitated the exchange of old and new models, there is a slot machine with a reel device detachably attached to the front door, and a middle frame between the housing and the front door that can be freely opened and closed. Some have a reel device attached to a middle frame. Further, there has been proposed an apparatus in which a saucer is detachably attached to a lower side of a front door.
[0003]
However, such a conventional slot machine has a common problem that it is troublesome to exchange old and new models. That is, the slot machine is replaced with a new model after a certain period of time. At this time, a method of removing the old model and attaching the new model to the removed space has been generally used.
[0004]
For this reason, it takes time to replace the old and new models, and in order to replace the models, the pachinko hall business hours are often shortened and nighttime work is often required, resulting in a problem that a lot of labor and cost are required. . In addition, since the new model and the old model are completely replaced, the cost for transporting and storing them is also high, and the old model is discarded and a new model is newly manufactured, which wastes resources. There were also points.
[0005]
Therefore, instead of replacing the new model and the old model in their entirety, the reel device and the main board are attached to the upper half of the front door that opens and closes the front opening of the main body box of the slot machine. It is proposed that only the upper half of the front door is detachably attached to the housing so that only the front door can be replaced (for example, see Patent Document 1).
[0006]

JP-A-13-95973 (paragraph [0049] and FIG. 1)
[0007]
[Problems to be solved by the invention]
However, in the above-described method, for example, in the case of a configuration in which various switches are left on the lower half side of the front door, these switches are frequently operated. Since the performance is deteriorated, there is a possibility that the reliability and the quality of the operation are deteriorated.
[0008]
In addition, the front door frame part is easily damaged in appearance, and only the front door frame has scratches instead of the new model, resulting in a bad impression for the player in terms of appearance It becomes.
[0009]
Therefore, an object of the present invention is to make it possible to exchange models with a simple configuration with good quality and good appearance.
[0010]
[Means for Solving the Problems]
In order to achieve the above-mentioned object, the present invention provides a housing having a front opening, a display window, and an effect unit for performing an effect according to the progress of a game and various operation switches. A front door that is openably and closably attached to one side of the reel, and a reel device that has a plurality of reels and a drive motor for these reels between the housing and the front door and faces the display window. A medal ejection device that ejects medals to a player based on a game result of the reel device, a main control device that controls the reel device and the medal ejection device, and a signal that is received from the main control device. An auxiliary control device for controlling the production means, a power supply device for supplying power to the reel device, the medal ejection device, the main control device and the auxiliary control device, and a centralized terminal plate having an external output terminal are provided. In the slot machine, the front door is detachably attached to the housing, the reel device, the main control device and the auxiliary control device are attached to the front door, and the inside of the housing is A medal discharge device, the power supply device, and the centralized terminal board are provided (claim 1).
[0011]
According to such a configuration, by separating the front door from the housing, the front door and the reel device, the main control device, and the auxiliary control device attached to the front door can be easily replaced for a new model. . At this time, the operation switches normally mounted on the front door are also replaced together, so that the models can be replaced with good quality and appearance.

According to such a configuration, since the reel device and the main control device can be separated from the front door, the volume of the packing box at the time of replacement is reduced as compared with a case where the reel device and the main control device are not separated from the front door. Advantageously.
[0013]
Further, the present invention is characterized in that the front door is formed so as to be able to be bent at a substantially central portion (claim 3). At this time, as described in claim 4, the front door may be formed to be bent at a plurality of locations.
[0014]
According to such a configuration, by folding the front door, the size of the packing box can be reduced, and the packing efficiency can be improved.
[0015]
In addition, the present invention is provided with a housing having an open front, a display window, and a rendering means for performing a rendering in accordance with the progress of the game, and various operation switches. A reel device having a front door attached thereto, a plurality of reels and a drive motor for driving these reels between the housing and the front door, the reel device facing the display window, and a game for the reel device. A medal ejection device for ejecting medals to a player based on the result, a main control device for controlling the reel device and the medal ejection device, and an auxiliary control for controlling the effect means in response to a signal from the main control device Device, a power supply device for supplying power to the reel device, the medal discharge device, the main control device and the auxiliary control device, and a centralized terminal plate having an external output terminal. Wherein the front door includes a door frame, a plurality of panel frames detachably attached to the door frame, and a plurality of panels detachably attached to each of the panel frames. (Claim 5).
[0016]
According to such a configuration, when exchanging the model, a plurality of panels are removed from each panel frame, so that only each panel needs to be exchanged, and the component cost required for the new model can be greatly reduced. Yes, the weight of parts required for the new model can be reduced and transportation becomes very easy. Since these panels can be easily replaced in the hall, the replacement operation can be performed very easily.
[0017]
At this time, as described in claim 6, the panel frame is separable into upper, middle, and lower, and the panels are detachably attached to the upper, middle, and lower panel frames respectively. Is desirable. In this way, in the case of a slot machine, it can be roughly divided into upper, middle, and lower from the viewpoint of the front decorative design. Therefore, if the upper, middle, and lower panels can be separated, the front door can be separated. The trouble of replacing a new design can be greatly simplified.
[0018]
Further, the present invention is characterized in that the main control device and the auxiliary control device are mounted on the reel device (claim 7). According to such a configuration, the main control device and the auxiliary control device can be exchanged together with the reel device, and the reel device with the main control device and the auxiliary control device can be exchanged in the hall. Can be improved.
[0019]
