Description

  The present invention relates to a gaming machine provided with a gutter member for discharging a game ball won in a winning opening.

  One of the conventionally known gaming machines is a so-called pachinko machine. The pachinko machine is provided with a game board, and a game area where a game ball flows down when a game is played in the game machine is formed on the surface of the game board. In this game area, various winning ports such as a normal winning port, a starting winning port and a large winning port are provided. The normal winning opening is a winning opening for paying out a predetermined number (for example, 10) of winning balls when a game ball is won, and the starting winning opening is a special advantage that is advantageous to the player from a normal gaming state that is disadvantageous to the player. It is a winning opening that triggers a lottery to determine whether or not to enter the gaming state. The big winning opening is a winning opening that is opened when a lottery is won and pays out a predetermined number (for example, 10) of winning balls when a game ball is won. In conventional gaming machines, there are various types such as one having only one of these various winning awards and one having a plurality thereof. Among them, there are a number of ordinary winning openings provided in the game area.

  On the back side of the game board, there is provided a back unit provided with a gutter member for discharging game balls won in various winning openings. The heel members are separately formed with a bowl that communicates with the normal prize opening, a bowl that communicates with the start prize opening, and a bowl that communicates with the large prize opening. A discharge path for discharging the gas is formed. These scissors members that communicate with a prize opening having the same function (for example, these ordinary prize openings in the case where a plurality of ordinary prize openings are provided) are respectively connected upstream of these prize openings. It is formed separately, and is formed so that the discharge passages merge into a single discharge passage at a predetermined position on the downstream side.

  The gaming machine is configured so that the detection sensor can detect that the game ball has passed through the discharge path in each cage described above, and a detection sensor is attached and held inside the cage member. A holding part is provided. Normally, one detection sensor is generally provided for each of the flange members, and one holding part is generally provided for each of the flange members. However, in the case where the discharge path is formed so as to merge into one like the collar member communicating with the above-described normal winning opening, a detection sensor is provided on the downstream side after the discharge paths merge into one. There are many cases. In this case, the holding unit is provided in the discharge path on the downstream side, and in the gaming machine, by providing a detection sensor in the holding unit on the downstream side, the number of game balls won in a plurality of winning holes is collectively collected. Processing such as detecting and paying out a predetermined number of prize balls can be performed.

  By the way, game machines are required to pass a type test before mass production. In the type test, it is one of the inspection items that the relationship between the number of game balls won in the winning opening and the number of winning balls paid out by winning is one of the inspection items. It is supposed to be done individually. Therefore, in the case of a saddle member formed so as to merge the discharge paths formed separately, it is possible to detect the passage of the game ball at a predetermined position on the upstream side where the discharge paths do not merge, Necessary for taking the inspection. Therefore, in conventional gaming machines, a detection sensor holding part is also provided on the upstream side where the discharge path has not yet joined, and when receiving a type test, the detection sensor is attached to this upstream side holding part. The passing of the game ball in the discharge path can be detected.

  However, the gaming machine is required to have the same configuration as the mass-produced product sold to the amusement store that has undergone the type test. Moreover, it is preferable that it is the same structure mentioned above also from a viewpoint of manufacturing cost. Therefore, the detection sensor holder used only in the type test is also provided in mass-produced gaming machines, and the detection sensor holder used in the type test exists without the detection sensor attached. It was. However, in such a state, if a holding unit for the detection sensor used only for the type test is also present in the mass-produced gaming machine, the detection sensor is improperly attached to the holding unit for the detection sensor, and more than actually won. There is a risk that cheating may be performed in an attempt to illegally acquire more prize balls as if the game balls have been won.

  In order to solve such a problem, for example, in Patent Document 1 shown below, a protrusion is formed so that the detection sensor cannot be attached to the holding part of the detection sensor used only for the type test. There is disclosed a gaming machine configured such that a detection sensor cannot be attached without destroying.

JP 2000-300775 A

  However, in the gaming machine described in Patent Document 1, the fragments of the protrusions that are generated when an unauthorized person improperly attaches the detection sensor are likely to fall into the discharge path, and the game balls that flow down in the discharge path are clogged. There was a problem that it is likely to become a factor that generates the. Moreover, since the gaming machine described in Patent Document 1 can attach the detection sensor by destroying the protrusion, there has been a problem that the above-described fraud cannot be reliably prevented.

  The present invention has been made in view of the above-described problems, and it is possible to prevent clogging of game balls flowing down in the discharge path and reliably prevent illegal acts of illegally acquiring a large number of prize balls. An object is to provide a possible gaming machine.
