Description

  The present invention relates to a pachinko machine for playing a game using a game ball.

  In the pachinko machine, while the game area (front side) of the game board is divided by the guide rail into a substantially circular game area, a variable display device, a winning opening (a start winning opening and a general winning opening) An attack device etc. is provided, and a lottery is performed when the game ball fired toward the game area has won the start winning opening, and based on the result of the lottery, the variable display device displays the variation of the production symbol and stops it. There are many models that are designed to display. Here, the start winning opening is provided with a ball detection sensor for electrically detecting a winning game ball, but the general winning opening is not provided with such a ball detection sensor.

  Conventionally, a decoration frame for decorating the game area is installed in almost the central part of the game board, and a warp passage through which the game ball flowing down the game area can enter is provided on the left side of this decoration frame. There is known a pachinko machine provided with a stage positioned directly above the start winning hole (see, for example, Patent Document 1). In such a pachinko machine, when the game ball flowing down the game area enters the warp passage, the game ball passes through the warp passage and is guided to the stage, and then rolls on the stage and then starts downward. In order to fall toward the winning opening, the probability that the game ball enters the warp passage increases the probability of winning in the starting winning opening.

  As described above, in a pachinko machine having a warp passage, when the game ball launched toward the game area enters the warp passage, the probability that the game ball will win in the start winning opening is high, so the pachinko machine is put on the market. At a manufacturing site or the like before shipping, it is necessary to check the degree to which the game ball enters the warp passage and wins the start winning opening. Therefore, conventionally, the game ball is continuously fired toward the game area within a predetermined time, and the quantity of game balls entering the warp passage is measured by the manual counter, and the measurement data satisfies the predetermined condition. In the case where the pachinko machine is used, it is shipped to the market as a good product.

  However, in order to obtain accurate data on the number of game balls entering the warp passage, for example, 100 game balls are shot continuously toward the game area in one minute, and the warp passage is entered among them. It is necessary to visually check and measure the number of game balls that have been made, and there is a problem that such measurement work is complicated and involves fatigue of an inspector.

  Therefore, as described in Patent Document 2, an opening is formed on the back surface side of the flow path through which the game ball passes, and the ball detection sensor is inserted and held in the opening to detect the ball detection sensor. It is conceivable to detect the passage of the game ball based on the signal. Specifically, an opening is formed on the back side of the warp passage, and the detection signal of the ball detection sensor inserted in the opening is counted to electrically check the degree to which the game ball enters the warp passage. The ball detection sensor, which has become unnecessary after the inspection, is removed from the opening, and the pachinko machine is shipped to the market in this state.

  By adopting such a method, since the gaming ball passing through the warp passage can be detected by the electric signal of the ball detection sensor, the visual inspection work manually measured by the operator can be omitted. Since the pachinko machine can be put on the market after the inspection with the ball detection sensor removed, the cost increase of the pachinko machine can be prevented with the addition of the ball detection sensor.

  However, when the ball detection sensor is detachable to the opening formed on the back surface side of the warp passage, the peripheral portion (edge) of the opening is formed on the inner peripheral surface of the warp passage. The behavior of the gaming ball passing through the warp passage and going to the stage slightly changes depending on when it is inserted and removed, and pachinko machines in the same state as the data acquired before shipment can be put on the market The problem of disappearing occurs.

  The present invention has been made in view of the circumstances of such prior art, and its object is to provide a pachinko machine which can be put into the market in the same state as data acquired using a detection sensor before shipment. It is to provide.

  In order to achieve the above object, the pachinko machine of the present invention is provided with a game board having a game area in which game balls can flow down, and a start winning prize which is disposed in the game area and generates a predetermined lottery chance.

  In the pachinko machine configured in this way, the detection sensor is inserted and held in the holding portion provided on the back surface of the specific flow path before shipping, and the game sensor without contact detects the gaming ball passing through the specific flow path by this detection sensor After that, since the detection sensor can be shipped to the market in a state of being extracted from the holding unit, it can be put into the market in the same state as the data acquired using the detection sensor before shipment.

  In the above configuration, the specific flow path may be anything as long as a part of the gaming ball flowing down the gaming area passes through, but a stage disposed above the start winning opening and capable of rolling the gaming ball, In the case of a pachinko machine provided with a warping passage for guiding the gaming ball flowing down the gaming area to the stage, it is preferable that at least the warping passage be a specific flow passage.

  According to the pachinko machine of the present invention, the data can be put into the market in the same state as the data acquired using the detection sensor before shipment.

The main control processing unit 28 includes a central processing unit (CPU), a read only memory (ROM) storing a predetermined control program, and a RAM (temporarily stored stored processing information and deleted stored information). A random access memory (Random Access Memory) or the like is mounted on the control substrate (main substrate), and the CPU reads and executes various programs and data stored in the ROM to perform main processing regarding the game.

  Next, the configuration of the passage unit 22 will be described in detail with reference to FIGS.

  The passage unit 22 is a molded product made of transparent resin, and the stage 20 and the warp passage 21 are integrally provided in the passage unit 22. The passage unit 22 has a support plate 34 extending along a vertical surface, and the support plate 34 is screwed to the lower part of the decoration frame 11.

  The stage 20 is a structure that protrudes in the forward direction of the support plate 34 and extends in the left-right direction. On this stage 20, the game ball entering the warp passage 21 is not only discharged but also enters the warp passage 21 The game ball which has flowed down the game area 8 is also possible to dive. In any case, the gaming ball that has reached the stage 20 rolls on the stage 20 and is guided to the induction opening 20a, and then falls from the induction opening 20a and enters the first start winning opening 12 with high probability. It is supposed to be a ball.

  The warp passage 21 is a passage (specific flow passage) where a part of gaming balls flowing down the game area 8 on the left side of the decorative frame 11 can enter, and the rear opening of the warp passage 21 is closed by the support plate 34 (See FIG. 11). That is, the support plate 34 also functions as a back plate of the warp passage 21, and a plurality of claw portions 35 which are holding portions are formed on the back surface of the support plate 34. The claws 35 are disposed at four locations corresponding to the respective apexes of the rectangle, and the upper two claws 35 are formed as L-shaped hook pieces, and the lower two claws 35 are formed in a bottomed shape. It is formed. Here, since the passage unit 22 including the warp passage 21 and the support plate 34 is made of a transparent material, gaming balls passing through the warp passage 21 can be seen from the front of the game board 7 through the transparent plate 4. However, the claws 35 scattered at four locations are less noticeable.

  A detection sensor 36 for detecting the gaming ball passing through the warp passage 21 in a noncontact manner can be inserted into and removed from such a claw portion 35, and in the case of this embodiment, a rectangular parallelepiped shape called a reed switch. A magnetic sensor is used as the detection sensor 36. However, the detection sensor 36 is inserted and held in the claw portion 35 at the time of inspection before shipping the pachinko machine, but is removed from the claw portion 35 at the time of shipping the pachinko machine to the market.

  That is, in the pachinko machine according to the present embodiment, when the game ball launched toward the game area 8 enters the warp passage 21, the game ball rolls on the stage 20 and the first start winning opening 12 In order to win with a high probability, it is necessary to check the degree to which the game ball enters the warp passage 21 and wins the first start winning opening 12 at a manufacturing site or the like before shipping the pachinko machine to the market. Therefore, as shown in FIG. 8 to FIG. 11, the detection sensor 36 is inserted and held in the claw portion 35 at the time of the inspection, and the detection sensor 36 detects the gaming ball passing through the warp passage 21 without contact. Thus, among the gaming balls continuously fired toward the game area 8 within a predetermined time, data of the degree of entering the warp passage 21 and winning in the first start winning opening 12 is acquired.

  Thereafter, as shown in FIGS. 4 to 7, the detection sensor 36 used at the time of inspection is extracted from the claw portion 35 and collected, and the pachinko machine is shipped to the market in this state. In that case, even if the detection sensor 36 is removed, no change occurs in the internal space of the warp passage 21. Therefore, it can be put into the market in the same state as the data acquired using the detection sensor 36 before shipment. In addition, since it is possible to ship in a state in which the detection sensor 36 unnecessary for the game in the market is collected, it is possible to prevent the cost increase of the pachinko machine accompanying the addition of the ball detection sensor.

  As described above, in the pachinko machine according to this embodiment, since the plurality of claws 35 are provided on the back surface of the warp passage 21, the detection sensor 36 is inserted in each claw 35 before shipment to the market. Among the gaming balls continuously fired toward the game area 8 within a predetermined time, the holding ball is detected in a non-contact manner by detecting the gaming ball passing through the warp passage 21 by the detection sensor 36 in a non-contact manner. The degree of winning and winning at the first start winning opening 12 can be easily checked based on the electrical signal output from the detection sensor 36. Then, after the inspection, the detection sensor 36 is removed from the claw portion 35 and then the pachinko machine is shipped to the market. Therefore, no change occurs in the internal space of the warp passage 21 even if the detection sensor 36 is removed. It can be put on the market in the same state as the data acquired using the detection sensor 36 before shipment.

  Further, in the above embodiment, the warp passage 21 and the support plate 34 closing the back surface are made of a transparent material, and the claw portion 35 is formed on the back surface of the support plate 34. It is possible to make the presence of the claws 35 inconspicuous while making the passing game balls visible. In particular, since the holding portion that allows the insertion and removal of the detection sensor 36 is configured by forming a plurality of small claw portions 35 in a dispersed manner, the presence of each claw portion 35 can be made even less noticeable. . However, it is also possible to adopt a holding portion having a structure different from such a claw portion 35. For example, a box-shaped holding portion having an open upper end is formed on the back surface of the warp passage. The detection sensor may be removable.

  In the above embodiment, the warp passage 21 has been exemplified as the specific flow path, but if the specific flow path is a flow path through which a part of the gaming balls flowing down the gaming area 8 passes, the warp is Not only the passage 21 but other parts may be used.

  For example, not only the back surface of the warp passage 21 but also the back surface of the stage 20 connected to the outlet of the warp passage 21 may be provided with a holding portion that enables the detection sensor 36 to be inserted and removed. Based on the output signal of each detection sensor 36, ratio data between the gaming ball that passes through the passage 21 and reaches the stage 20 and the gaming ball that jumps directly from the gaming area 8 to the stage 20 can be acquired. Alternatively, a holding portion may be formed on the back surface of the high probability route from the induction port 20a of the stage 20 to the first starting winning opening 12 so as to allow the detection sensor 36 to be inserted and removed. It is possible to acquire data of a rate at which the reached game ball wins the first start winning opening 12.

  When the holding portions are respectively formed in a plurality of specific flow paths in this way, the number of detection sensors required at the time of inspection before shipment increases accordingly, so all detection sensors are removed from the holding portions. If the pachinko machine is put into the market in the state, the cost can be significantly reduced along with the recovery of the detection sensor.
