Japanese Patent Laid-Open No. 2003-81411 (pages 3, 4 and 3-8)

  By the way, in recent pachinko machines, the size of the display unit of the symbol display device has been increased, and the symbol control board has also been increasing in size in order to perform an advanced game production utilizing the large display unit. It is in. However, in order to increase the size of the symbol display device and the symbol control board, it is necessary to increase the size of the ball gathering cover to which these symbols are attached. On the front of the back set board facing the back of the game board, the path of the game ball as described above. Since the mechanism is provided, the ball gathering cover has a large design limit for avoiding interference with the back set panel, and it is difficult to design the conventional mounting mechanism in response to the trend toward larger symbol display devices. There was a problem.

  Moreover, when the symbol control board which protrudes on the back side is enlarged and the case body which accommodates it is enlarged, it is necessary to enlarge the opening provided in the back set board. Further, in a pachinko machine in which the back set board and the front frame are assembled via a hinge mechanism, the case body is used to avoid interference between the edge of the opening and the case body when the back set board is opened and closed. It is necessary to form an opening larger in the opening / closing direction (lateral direction) than the dimension of. For this reason, in the conventional mounting mechanism, the degree of freedom of arrangement of other mechanisms and devices arranged on the back set board is limited by the enlargement of the opening of the back set board accompanying the increase in the size of the symbol control board. Or the design margin for further opening in the opening and closing direction is lost, making it difficult to configure the back set board in an assembled form via a hinge mechanism. Also, if the design control board is downsized, there is a risk that the level of performance will be reduced and the game will be lost. If the level of performance is maintained by further improving the high-density mounting, the heat generated from the circuit will become more prominent. As a result, there arises a new problem that the possibility of causing malfunction of the circuit increases.

  In addition, a liquid crystal panel that is generally used as a display of a symbol display device of a pachinko machine has a backlight life of about 10,000 to 50,000 hours, and the number of days used in a game facility is 2 The calculation will enable operation for more than a year. However, on the other hand, in the gaming facilities, the installation priority of popular models and new models is extremely high in providing gaming services in a limited space, and it is renewed in about 3 to 6 months for general pachinko machines It is in the present condition to be forced. For this reason, when the board is changed due to the model change, the liquid crystal panel with sufficient life is discarded along with the game board, and a new liquid crystal panel is attached to each model, and the game board is manufactured. This has been a problem as one of the reasons for the high manufacturing cost of pachinko machines.

  In view of the above problems, an object of the present invention is to provide a ball game machine that can be attached to a large symbol display device and can be manufactured at a low cost.

  To achieve the above objective, a game board having a game area formed on the front surface, a front frame that accommodates and holds the game board in a standing posture, and is located on the back side of the game board and always covers the back of the front frame. In a ball game machine equipped with a back set board and a symbol display device that displays a symbol according to game development, the perspective view is located in the game area so that the back side can be seen from the front side. The rear surface of the back set board is provided with an engaging projection protruding from the bracket member that forms a region and is detachably attached to the back surface of the back set board, and an engagement receiving portion that engages with the engagement protrusion is provided on the symbol display device. A bracket member is detachably attached to the bracket, and an engagement protrusion is provided on one of the bracket member and the symbol display device, and an engagement receiving portion that engages with the engagement protrusion is provided on the other, and the bracket member is attached to the back set board. , The back set board on the back of the front frame And a covering position, when engaged with the engagement projection and the engagement receiving portion are arranged so as to face the front of the display unit of the symbol display device via the transparent region.

  The display device mounting mechanism of a ball game machine according to the present invention has a configuration in which a symbol display device, which has been conventionally mounted on a ball cover on the back side of the game board, is attached to the back set board. With such a configuration, it is possible to increase the size of the symbol display device, which has conventionally been difficult due to the limitation in increasing the size of the ball-throwing cover due to design restrictions for avoiding interference with the back set board. it can. Furthermore, since the symbol display device can be attached from the back side, the opening provided in the back set board for accommodating the case body protruding from the back side of the display unit has at least the display unit facing the front side of the game board. Therefore, it is sufficient if the size is set to be large enough to increase the degree of freedom in disposing other mechanisms and devices provided on the back set board. Furthermore, since a design margin for forming the back set board in an assembled form via a hinge mechanism is formed, it is possible to attach a large symbol display device and provide a ball handling machine with high operability. Can do.

  In addition, since the symbol display device that was previously attached to the game board that is attached and removed when the model is changed is attached to the back set board that can be used from the old model to the new model, It is no longer necessary to install and manufacture a new symbol display device each time. For this reason, it is possible to provide a bullet ball game machine that can use the symbol display device in view of the lifetime and suppress the manufacturing cost.

  Furthermore, the symbol display device is configured to be attached to the back set board via a bracket member provided with either one of an engagement protrusion or an engagement receiving portion which is a fixture. For this reason, for example, even when it is necessary to change the size of the liquid crystal panel in accordance with the change of the panel accompanying the change of the model, the arrangement position of either the engagement protrusion or the engagement receiving portion is changed. By manufacturing the bracket member, it is possible to support the mounting of the symbol display device regardless of the size, so the size of the indicator, control board, etc. of the symbol display device has been changed with the change of model In addition, it is possible to provide a ball game machine that can be mounted on the back side of the back set board.

It can be easily accommodated by mounting. As described above, the attachment mechanism 150 having this configuration can attach the symbol display device 30 of various sizes.

  In each of the above embodiments, the engaging protrusion is integrally provided on the back set panel 90 or the flat plate portion 51 of the bracket 50. However, in each of the configuration examples, the engaging protrusion may be configured to be movable. FIGS. 6 to 8 show a configuration example in which the engagement protrusion is movable in the mounting mechanism using the bracket. Hereinafter, the mounting mechanism 160 of the configuration change example when the bracket is used with reference to these drawings. , 170 will be described. In addition, also in the attachment mechanisms 160 and 170 of these modified examples, the same members are denoted by the same reference numerals, and redundant description is omitted.

  First, a configuration example in which the engaging protrusion is movable will be described with reference to FIGS. The brackets 60 and 60 of the mounting mechanism 160 shown in FIGS. 6 and 7 are formed with the same outer dimensions as the bracket 50 of the above embodiment, and the flat plate portion 61 and the folded portion 62 are formed in the same manner. The flat plate portion 61 is provided with a substantially groove-shaped guide groove 61a formed extending in the vertical and horizontal directions. Further, the engaging protrusion 67 having the outer shape formed in a truncated cone shape similar to that of the engaging protrusions 97 and 57 of the above embodiment and provided with the screw receiving hole 67c on the bottom surface is provided with the guide groove 61a from the back surface of the flat plate portion 61. And is fixed to the position on the guide groove 61a. Further, the protruding end portion 67a of the engaging projection is formed in a cylindrical shape having a screw receiving hole 67b as in the above embodiment, and the outer diameter is formed to be substantially the same as the inner diameter of the receiving groove 34a.

  When the bracket 60 is fitted into the accommodating space 90b formed by the rectangular frame-shaped ribs 98 disposed on both sides of the opening 90a in the same manner as in the above-described embodiment, The engagement protrusion 67 provided on the part 61 is in a state of protruding to the back side of the back set board 90.

Further, in this configuration, by selecting the locations of the guide holes 71a, 71a,... To which the engagement protrusions 77 are attached, the arrangement intervals of the engagement protrusions 77 are multi-staged according to the drilling intervals of the guide holes 71a. Can be adjusted vertically and horizontally. Therefore, as in the above embodiment, even when the arrangement interval of the engagement receiver 34 of the symbol display device 30 is changed due to the change of the model, the engagement is achieved by selecting the guide hole 71a for fixing the position. By adjusting the arrangement interval of the protrusions 77 in the vertical and horizontal directions, it is possible to cope with the attachment of the symbol display device 30 from the back side of the back set panel.

  Further, the configuration described in FIGS. 6 to 8 is not limited to the application only when the bracket is used. For example, the back set board 90 can be configured by penetrating a groove formed in a substantially square shape in the same manner as the guide groove 61a of the above embodiment and attaching an engaging projection to this groove. The back set board 90 can also be configured in the same manner by drilling matrix-like holes arranged in the vertical and horizontal directions in the same manner as the guide holes 71a of the above embodiment and attaching engaging projections to these holes. An effect can be obtained.

  The guide groove 61a is not limited to the form shown in FIG. That is, it is not necessary to form grooves so as to communicate with each other as shown in the drawing, and the number of grooves extending in the vertical and horizontal directions may be set to be larger or smaller. Similarly, the number of drilled guide holes 71a, the drilling interval, etc. are not limited to the mode shown in FIG. 8, but any mode is possible as long as a plurality of through-holes can be provided to change the arrangement interval of the engaging projections. You may form in.

  In each of the above embodiments, the engagement protrusion is provided on the back surface of the back set panel 90, and the engagement receiving portion that engages with the engagement protrusion protrudes outward from the case half 33 of the symbol display device 30. However, the present invention is not necessarily limited to this configuration, and any configuration is possible as long as the symbol display device 30 can be attached from the back side of the back set panel 90. The arrangement positions of the engagement protrusions and the engagement receiving portions are as described above. You may comprise reverse to an example. Even if comprised in this way, the symbol display apparatus 30 can be attached similarly to said each Example, and the same effect can be acquired.

  In addition, the back set board 90 is configured to be opened and closed laterally via the hinge mechanisms 6a and 6b and detachably assembled to the front frame to improve handling, but only the back set board locking tool 9 is used. Even if the display device mounting mechanism according to the present invention is applied to a pachinko machine that has been assembled by being locked and used, it is possible to mount a large symbol display device and use it in light of the life of the symbol display device. A similar effect can be obtained.

  In each of the above embodiments, a pachinko machine is exemplified as a bullet ball game machine to which the display device mounting mechanism according to the present invention is applied. However, an arcade game machine and a smart ball machine are also illustrated as in this embodiment. Can be applied in the same manner to obtain the same effect as long as it is provided with other mechanism boards, mechanism frames and the like on the back side of the game board.
