Description

  The present invention relates to a pachinko machine that uses a game ball to play a game, and more particularly, to a pachinko machine equipped with a detection sensor for detecting fraud using a magnet or the like.

  In the pachinko machine, the board surface (front surface) of the game board is divided into a substantially circular game area by a guide rail, and a variable display device, a winning opening (start winning opening and general winning opening), Arranging an attacker device, etc., a lottery is performed when the game ball launched toward the game area wins the start winning opening, and based on the lottery result, the variable display device displays and stops the change of the production symbol There are many models that can be displayed. The lottery results include winning (winning) and non-winning (losing), and if the lottery results are winning, a combination of predetermined design symbols is displayed on the display screen of the variable display device, and the normal mode is changed to the special game mode. And migrate. In this special game mode, the open / close door of the attacker device opens to expose the big prize opening, so that it becomes easy for the game balls to enter the exposed big prize opening and it is possible to acquire many prize balls. Note that if the game ball flowing down the game area does not win any of the winning prize openings, such as the start prize opening or the big prize opening, this game ball will be drawn from the out mouth provided at the lowest position of the game area. It is designed to be discharged to the back side.

  In such a pachinko machine, a magnet is brought close to a transparent plate (glass plate) that covers the surface of the game board, and the game balls are directly guided to the start winning opening, etc., or a large number of game balls are collected at predetermined locations in the game area. In other words, there is a problem of cheating (going action) that makes it easy to win a start winning opening (making a so-called grape state). Therefore, in recent pachinko machines, in order to prevent illegal acts using such magnets, the back of the game board located above the start winning opening, the board unit provided on the back side of the game board, etc. Measures are taken such as attaching a detection sensor (magnetic sensor) to an arbitrary place using an appropriate fixing means, detecting the magnetic force of the magnet with this detection sensor, and stopping the launch of the game ball. For example, in the pachinko machine disclosed in Patent Document 1, a sensor positioning unit is provided at a predetermined position of a center accessory unit disposed in a game area, and a rectangular parallelepiped detection sensor is stored in a bottomed box-shaped case. In this state, this case is screwed and fixed to the sensor positioning portion of the center accessory unit.

JP 2010-252928 A

  In the conventional pachinko machine disclosed in Patent Document 1, since the case housing the detection sensor is screwed to an arbitrary position of the game board, the positional relationship between the detection surface of the detection sensor and the transparent plate is properly maintained. The detection sensor can perform detection with uniform accuracy. However, since it is necessary to attach the detection sensor using a dedicated case, there are problems that the cost of parts increases due to the case, and the assembly work becomes complicated.

Can be detected.

  In this case, if the first restriction wall is disposed at the front position closest to the entrance of the out mouth, the detection surface of the magnetic sensor can be brought closer to the transparent plate (glass plate) covering the game area to improve the detection accuracy. At the same time, even if a person who intends to act illegally inserts a finger or a foreign object from the outlet and tries to remove the magnetic sensor, it is possible to make it extremely difficult to remove the magnetic sensor due to the presence of the first restriction wall.

  In the pachinko machine of the present invention, when a detection sensor for detecting an illegal act that inhibits a game is attached to the installation part, the detection sensor is inclined along the longitudinal direction from the first regulating wall side between the pair of hook pieces. When inserted, the outer wall surface of the detection sensor fits into a recess surrounded by the first restriction wall, the second restriction wall, and both hook pieces, so that the detection sensor can be easily attached to the installation portion without using a special case. be able to. Further, in such an attached state, the vicinity of one end portion of the detection sensor in the longitudinal direction contacts the first restriction wall and the second restriction wall, and the vicinity of the other end portion of the detection sensor in the longitudinal direction is engaged with the claw portions of both hook pieces. Since the finger and the nail are not easily caught by the detection sensor attached to the installation portion, it is possible to prevent the detection sensor from falling off and to make it difficult to remove.
