JP-A-2016-144506

In this type of game machine, a large number of resin molded products such as a production board case and a back cover are adopted. When manufacturing such a molded product, an injection molding method is adopted in which a molten resin is poured into a cavity between a fixed mold and a movable mold at a high pressure to form the molded product.
The board cases such as the production board case and the main board case are made of colorless and transparent resin so that the display information of the board management information display part of the board can be visually recognized from the outside, and the back cover is the display information on the board case side and the board side. The display information is made of colorless transparent or colored transparent resin so that it can be visually recognized from the back side.
When molding these substrate cases and back covers with resin, the molten resin is poured into the cavity from the resin pouring portion on the fixed mold side at high pressure to mold, and then the movable mold is retracted to open the mold. Next, the resin part is extruded by the extruded portion on the movable mold side and removed. Therefore, the traces of the resin molding portion such as the trace of the resin pouring portion and the trace of the extruded portion used at the time of molding remain on the substrate case and the back cover.
However, since most of the traces of the resin molding part are uneven, if the traces of the resin molding part overlap with specific parts such as the substrate and the information display part of the substrate case, the light is diffusely reflected at the traces of the resin molding part. Therefore, the trace of the resin molded portion becomes an obstacle and the visibility of the display information and the like from the back side of the back cover is lowered.
If the substrate case, back cover, etc. have heat dissipation holes, weld lines are generated on the downstream side of the heat dissipation holes when the substrate case and back cover are molded. Therefore, the substrate corresponds to the heat dissipation region in which a large number of heat dissipation holes are formed. When the board management information display unit on the side is arranged, there is a drawback that the weld line formed on the downstream side of the heat dissipation hole becomes an obstacle and the visibility of the display information is lowered.
In view of such conventional problems, an object of the present invention is to provide a gaming machine capable of preventing a decrease in visibility when the main part of the back member is visually recognized from the back side of the back cover that protects the back member. To do.

According to the present invention, in a gaming machine including a back member including a board case for accommodating a substrate and a resin back cover for visually protecting the back member side, the back cover specifies the board case side. The trace of the resin molding part provided at the time of resin molding of the back cover is arranged at a position that does not overlap with the part.
The substrate is a main substrate for controlling a game operation, and the substrate case may be a first substrate case for accommodating the main substrate. The back cover may overlap with the first substrate case, and the trace of the resin molded portion may be arranged at a position not overlapping with the first substrate case. The back cover may not overlap with the first substrate case and may protect the back member other than the first substrate case. The trace of the resin molding portion may be a trace of the resin pouring portion at the time of molding. The resin molded portion trace may be an extruded portion trace at the time of molding.

According to the present invention, there is an advantage that deterioration of visibility when the main part of the back member is visually recognized from the back side of the back cover covering the back member can be prevented.

The advantages are "less pressure loss due to the gate" and "simple structure, low cost and hard to break". On the other hand, the disadvantages are that "gate cut is required in the post-process", "gate cut trace is large", "many pieces cannot be taken", and "multi-point cannot be made".

(2) Side gate (2-plate mold)
The advantages are "the pressure loss due to the gate is relatively small" and "the structure is simple, inexpensive and hard to break". On the other hand, the disadvantages are that "gate cut is required in the post-process" and "gate marks remain".

(3) Submarine gate (2-plate mold)
The advantage is that "gate cutting is not required in the post-process". On the other hand, the disadvantages are that "it can be installed only on the side" and "the gate mark is not convex but dirty".

(4) Pin gate (3 plate mold)
The advantages are that "gate cutting is not required in the post-process", "gate marks are small and inconspicuous", "multi-point / multi-piece removal is easy", and "uniform pressure distribution can be easily obtained". On the other hand, the disadvantages are that "the amount of material used is large because the runner is long", "the mold size is large", and "the structure is complicated and expensive".

The extruded portion traces 91a and 91b are traces of the extruded portion such as an extruding pin contacting the molded product during die cutting, and are spaced apart from the lower end surface of the body portion 68 and the lower surface of the step portion 69 in the circumferential direction. Multiple are arranged. The extruded portion trace 91b on the lower surface of the step portion 69 has a circular shape, and the extruded portion trace 91a on the lower end surface of the body portion 68 has a semicircular shape smaller than the extruded portion trace 91b on the step portion 69 side. Therefore, at the time of molding, two types of extrusion portions having different sizes are used according to the conditions of each extrusion position of the operation button 64.

Here, the "extruded portion trace" will be briefly described. In addition, although the name "extruded part trace" often appears in the explanations so far and the following explanations, instead of this, "extruded pin traces, ejectors" which are universally used among those skilled in the art (extruded pin traces, ejectors) The name "Ejector) pin trace" may be used (replaced). Further, in this case, what corresponds to the "extrusion means" is an "extrusion pin (also synonymous with an extrusion pin), an ejector pin".

When molding the resin of the operation button 64, as shown in FIG. 15, the resin pouring portion corresponding to the resin pouring portion trace 90 melts into the cavity between the fixed mold and the movable mold in the direction indicated by 90a. The resin is poured and molded into a predetermined operation button shape. The resin pouring portion trace 90 is located at a substantially central portion in the vertical direction of the body portion 68, and the molten resin is poured in the radial direction (90a arrow direction) from the resin pouring portion corresponding to the resin pouring portion trace 90. Therefore, it is possible to pour the molten resin substantially uniformly into the entire cavity at the time of molding, and it is possible to prevent the generation of weld lines due to the merging of the molten resins.

Here, the "weld line" will be briefly described. If a pin or core is provided in the molded product to form a hollow part, the resin will diverge in that part, and when it goes around that part, it will rejoin, so a thin line ( Line) will occur. In resin molding, the "thin line generated at the portion where the flow of molten resin merges and is fused in the mold" is the weld line, but it may also be referred to as a weld line or a weld line.

The name "weld line" often appears in the explanations so far and thereafter, but instead of this, "a line that can occur at the resin confluence (during resin molding)" or "resin". It may be expressed as "merging line, resin merging line" or the like. The process until the weld line is formed is shown below.

As shown in FIG. 15, the molten resin poured from the resin pouring portion in the radial direction 90a arrow indicates the left-right direction (90b arrow direction, 90c arrow) in the entire cavity on the back side of the body portion 68 from the resin pouring portion. It flows substantially uniformly and radially in the indicated direction) and the vertical direction (90d arrow indicating direction, 90e arrow indicating direction). For example, the molten resin flows from the resin pouring portion into the cavity of the body portion 68 in the left-right direction (90b arrow direction, 90c arrow pointing direction), and flows from the resin pouring portion into the cavity of the body portion 68 in the vertical direction (90d arrow). Flows in the indicated direction (90e arrow indicated direction).

However, when the molten resin flowing in the left-right direction (90b arrow direction, 90c arrow direction) reaches the left and right notches (flow obstruction) 68a on the front side thereof, the notch 68a moves the molten resin forward. Since the flow is hindered, the molten resin does not flow from both the left and right sides to the front side of the body portion 68 beyond the notch portion 68a. On the other hand, the molten resin flowing in the upward direction (direction indicated by 90d) is in a state of communicating with the front side of the body portion 68 via the top side of the operation portion 70 between the left and right notch portions 68a of the cavity. It flows to the front side of the body portion 68 through the top side of the operation portion 70 between the left and right notch portions 68a.

When the molten resin in the cavity is cured, the mold is opened after that, and the molded product is extruded by the extruded portion on the movable mold side to be removed from the movable mold. A plurality of extruded portion traces 91a and 91b are arranged in the circumferential direction on the lower end surface of the body portion 68 of the operation button 64 and the lower surface of the step portion 69, and the extruding portion of each extruded portion corresponding to the extruded portion traces 91a and 91b is extruded. Therefore, the molded product of the operation button 64 can be easily removed from the movable mold.

After that, if the runner or the like is cut with a tool, a predetermined operation button 64 can be obtained, and the operation button 64 has a resin pouring portion trace 90 having a shape corresponding to the resin pouring portion on the outer periphery of the body portion 68. Remaining, recessed extruded portion traces 91a and 91b remain on the lower end surface of the body portion 68 and the lower surface of the step portion 69.

By injection molding the operation button 64 in this way, the molten resin separated into two hands does not merge in the cavity for the operation button 64, and the generation of weld lines can be prevented. Therefore, the strength of the operation button 64 is improved, and even when the player during the game frequently hits or presses the operation button 64, the strength sufficient to withstand the impact can be secured.

Moreover, although the resin pouring portion trace 90 having a shape corresponding to the resin pouring portion remains, the resin pouring portion trace 90 is at one place and is the rear part of the body portion 68, so that the weld line does not occur. Therefore, the aesthetic appearance of the operation button 64 is improved. Further, recessed extruded portion traces 91a and 91b remain on the lower end surface of the body portion 68 and the lower surface of the step portion 69, but the extruded portion trace 91b on the step portion 69 side is large depending on the shape and structure of the operation button 64. Since the extruded portion trace 91a on the lower end side of the body portion 68 is small, the extruded portion can be arranged according to the portion of the operation button 64.

As shown in FIGS. 1, 2, and 10, the front door 4 is provided with first to fifth warning display means 120 to 124 at required locations. The first attention alert display means 120 displays the precautions regarding the assembly of the movable effect means 97 to the game machine installer, and is near the movable effect means 97 on the upper surface of the lateral main body 95 of the second upper unit 58. It is provided in. The second caution display means 121 directly or indirectly displays the precautions regarding the assembly of the second upper unit 58 to the game machine installer, and is on the right side of the vertical main body 96 of the second upper unit 58. It is provided on the upper side.

The third caution display means 122 directly or indirectly displays the precautions regarding the operation of the movable effect means 97 to the player, and the movable effect means on the front side surface of the vertical main body 96 of the second upper unit 58. It is provided near the lower side of 97. The fourth attention alert display means 123 directly or indirectly displays the precautions regarding the operation of the second operation effect means 47 to the player, and is provided near the lower side of the second operation effect means 47. .. The fifth attention alert display means 124 directly or indirectly displays the precautions regarding the operation of the first operation effect means 46 to the player, and the first operation effect is displayed on the front surface or the upper surface of the lower cover 62. It is provided in the vicinity of the means 46.

The first caution display means 120 relates to an assembly work of assembling the movable effect body 114 of the movable effect means 97 in a protruding state, except for some precautions related to less important work when there are a plurality of work steps. Display precautions for major work processes that are of high importance to call attention. For example, when installing the game machine 1 on the island facility, after attaching the package of the game machine 1 to the island facility, the movable effect body 114 is unlocked by the locking means at the storage position 114D, and the movable effect body 114 is released. It is necessary to perform each assembling work of rotating the movable effect body 114 from the storage position 114D to the protruding position 114C around the front-rear axis and locking the movable effect body 114 again by the locking means so as not to rotate at the protruding position 114C.

Therefore, the first alert display means 120 "1. unlocks the movable effect body at the stored position. 2. rotates the movable effect body to the protruding position. 3. locks the movable effect body at the protruding position." When it is necessary to set the movable effect body 114 at the protruding position 114C through a plurality of work processes as in the above, the movable effect body except for some precautions regarding less important work such as a self-explanatory work process. Precautions regarding important work that should be noted when setting 114 safely are displayed, and the displayed items call attention to the operator.

If the important assembly work process when assembling the movable effect body 114 in the protruding state is explicitly displayed by the first caution display means 120 arranged in the vicinity of the movable effect means 97 in this way, the operator Can easily grasp which work process should be paid attention to when assembling the movable effect body 114, and is safe by proceeding according to the precautions of the first caution display means 120. Moreover, the movable effect body 114 can be efficiently set in the protruding state.

Further, the first caution display means 120 displays precautions related to important work for safely setting the movable effect body 114, except for precautions related to less important work such as a self-explanatory work process. Therefore, it is possible to display indispensable precautions in an easy-to-understand manner in the limited display area of the first alert display means 120 as compared with the case where all the matters are covered in detail. As a result, it is possible to prevent the occurrence of work mistakes of the operator as much as possible. Further, since it is not necessary to increase the size of the first alert display means 120, it does not spoil the aesthetic appearance of the entire game machine 1.

Moreover, since the movable effect body 114 is provided on the second upper unit 58 and the second upper unit 58 is removable from the door frame 55, the first caution display means 120 is also the movable effect body 114. Similarly, by providing the second upper unit 58, even when the second upper unit 58 is removed from the window frame, the movable effect body 114 and the first alert display means 120 do not become separate, and the first There is an advantage that the display related to the movable effect body 114 of the caution display means 120 can be easily confirmed at any time, and the management becomes easy.

The second caution display means 121 displays precautions regarding mounting work when mounting the second upper unit 58 on the door frame 55. When the second upper unit 58 is attached to the door frame 55, the second upper unit 58 is arranged on the front side of the door frame 55, and the engaging hook 100 of each engaging means 98 is engaged with the door frame 55. After engaging with the portion 102, the engaging hook 100 is clamped by the clamping means 103 corresponding to any of the engaging means 98 on the back side of the door frame 55 to tighten the engaging means 98 so as not to be disengaged, and finally. The fastening screw 110 of the fastening means 99 is operated from the back side of the door frame 55 to fasten the reinforcing plate of the second upper unit 58 to the door frame 55 side.

Therefore, the second caution display means 121 states, "1. Engage the engaging means with the door frame. 2. Clamp the engaging means with the clamping means. 3. Fasten the second upper unit to the door frame side with the fastening screw. When it is necessary to mount the second upper unit 58 on the front side of the door frame 55 through a plurality of work processes such as ".", Some precautions regarding less important work such as a self-explanatory work process. Except for, the precautions regarding important work to be noted in safely mounting the second upper unit 58 are displayed, and the operator is alerted by the displayed items. Therefore, the same effect as that of the first alert display means 120 can be obtained.

The third caution display means 122 is provided on the front side surface of the lateral main body portion 95 of the second upper unit 58 near the lower side of the movable effect means 97. Since the movable effect body 114 of the movable effect means 97 moves back and forth between the origin position 114A and the advance position 114B, if the player in the game stands up when the movable effect body 114 is located at the advance position 114B, it advances. There is a fear of hitting the head with the movable directing body 114 at the position 114B. Therefore, on the third warning display means 122, along with a warning display such as "Caution overhead!", Precautions for moving the movable effect body 114 back and forth or for the movable effect body 114 at the forward position 114B are displayed by characters, figures, etc. The display is designed to draw the player's attention.

The fourth caution display means 123 is provided on the front side surface of the vertical main body 96 of the second upper unit 58 near the lower side of the second operation effect means 47. Since the operation unit 118 of the second operation effect means 47 moves back and forth between the origin position 118A and the forward position 118B, when operating the operation unit 118, a finger is moved between the front surface of the vertical main body 96. There is a fear of pinching. Therefore, on the fourth caution display means 123, along with a warning display such as "Caution for pinching fingers!", Precautions for pinching fingers are displayed by characters, figures, etc., and the periphery of the second operation effect means 47. It is affixed in the vicinity.

If the operation unit 118 of the second operation effect means 47 is located at the forward position 118B and there is a risk that the player's body, arms, etc. may come into contact with the operation unit 118, the fourth caution display means. Different notes may be displayed on 123. Different precautions regarding the operation unit 118 may be displayed individually or separately.

The fifth caution display means 124 is provided on the lower cover 62 in the vicinity of the first operation effect means 46. For example, the first operation effect means 46 has three operations: a first operation of up and down movement by pressing the operation button 64, a second operation of rotation light emission operation by rotation light emitting means 67, and a third operation of vibration operation by vibration means 66. It is possible. In such a case, the fifth attention alert display means 124 directly or indirectly displays the precautions regarding the operation of the first operation effect means 46 to call the player's attention. The attention-calling information of the first movement, which has a high degree of attention to the player, is displayed without displaying the movements having a low degree of attention to the player, such as the second movement and the third movement.

When the first operation effect means 46 performs a plurality of operations of the first to third operations, if all the attention information for each operation is displayed on the fifth attention display means 124, the attention by displaying the attention information is displayed. The effectiveness of the arousal effect is rather reduced. That is, even if the fifth alert display means 124 is provided on the lower cover 62 on the front surface of the game machine main bodies 2 and 3, the arrangement area is also limited in space, and it cannot be secured indefinitely. Therefore, if all the alert information for each operation of the first operation effect means 46 that performs the first to third operations is displayed, the display of each alert information becomes too small and it becomes difficult for the player to confirm, and the alert is alerted. The effect of alerting by displaying information is rather reduced. However, if the fifth alert display means 124 displays the alert information of the first operation having a high degree of alert to the player, the player can accurately grasp the alert information.

The degree of alerting to the player may be determined by the amount of movement of the operation buttons 64 in the first to third operations. For example, the first operation of the up-and-down operation has a large amount of movement of the operation button 64, the second operation of the rotary light emission operation has no movement of the operation button 64, and the third operation of the vibration operation by the vibrating means 66 is the operation button 64. When the movement amount of is small, the fifth caution display means 124 displays the caution information regarding the first operation in which the movement amount of the operation button 64 is large, as described above.

Since the operation button 64 of the first operation effect means 46 is made of resin and may be damaged if a large impact force is applied, the fifth caution display means 124 may include "Caution for damage to the operation button!" Along with the warning display, precautions regarding damage to the operation button 64 may be displayed by characters, figures, or the like. In this case, it can be said that the precautions regarding the damage of the operation button 64 are the alert information having a high degree of alert to the player.

Also in the movable effect means 97, the first operation in which the movable effect body 114 moves between the origin position 114A and the forward position 114B, and the movable effect body 114 vibrates at the origin position 114A and / or the forward position 114B. Since two movements of two movements are performed, when displaying the warning information by the third warning display means 122, the second movement having a small movement amount is not displayed, and the first movement having a large movement amount is noted. The arousal information may be displayed.

The same configuration may be used when the fourth warning display means 123 displays the warning information regarding the second operation effect means 47.

It should be noted that the caution display means 120 to 124 are generally composed of a display sheet on which precautions are printed, and the display sheet is generally attached to a predetermined place by adhesive, adhesive, etc., but caution is given instead of the display sheet. A reminder display or other reminder information may be displayed by printing, engraving, or the like. Further, the alert information displayed on the third to fifth alert display means 122 to 124 may be any one that calls attention to safety precautions and characteristic matters in operation or operation of the target location. ..

Here, the disclosure of the alert information to the player or the game machine installer will be described.

<1. Attention to players>

<1-1> When there are a plurality of movements in the same movable body For example, in the movable effect means 97, the movable effect body 114 pops out toward the front (first operation) and the front surface of the movable effect body 114. Consider the case where there are two light emitting operations (second operation) in which the light emitting unit on the side emits light. As a potential risk of the first movement of the movable effect body 114, a player who does not know the existence of the first movement puts a wallet, a cigarette, or other small item on the movable effect body 114, or is placed above the game machine. If you reach out to see the data display on the side of the Tajima facility, it is possible that small items may fall from the movable effect body 114 or your hand may hit the movable effect body 114. ..

Further, as a potential risk of the second movement of the light emitting unit, when a player who does not know the existence of the second movement makes a violent light emission at the timing of staring at the light emitting part of the movable effect means 97, he / she looks at the eyes. There is a risk of injury. However, it is widely known to players that a predetermined portion of a game machine emits light, and it can be said that the movable effect means 97 emits light within a certain range of assumption.

Therefore, when calling attention to the effect operation of the movable effect means 97, "movable (at least a part of the position changes)" and "light emission (at least a part of the color changes, or changes from an extinguished state to a lighting state)". , Or changes from a low-intensity light-emitting state to a high-intensity light-emitting state) ”, since it can be said that the potential risk is greater if the“ movable ”is not known, the first warning display means 120 is used to call attention. As for the priority (“attention level”), “movable” is higher than “light emission”.

Therefore, the first alert display means 120 mainly displays the precautions regarding "movability" of the first operation having a high priority at least in a large size, and omits the precautions regarding "light emission" of the second operation having a low priority. Or display it small.

<1-2> When there are multiple movable bodies that perform the same type of operation As shown in 1-1, it can be said that "movable" has a higher potential risk than "light emission", but the same type of operation Even if it is (light emission, movable), it is possible that there is a difference or difference in the amount of movement (degree of movement).

For example, even when the operation type is "light emission", the former has a greater burden on the eyes and is higher when the light emission state is changed from the off state to the high brightness light emission state. There is a big difference in the burden on the player between the case of high-intensity blinking and the case of lighting (non-blinking) or low-intensity low-speed blinking (gradation emission), such as the former having a greater burden on the eyes.

Furthermore, even when the movement type is "movable", there is a risk that the former will hit the hand or head when the movement amount is large (for example, moving 20 cm) and when the movement amount is small (for example, moving 5 cm). In addition, when the movable body pops out and when the movable body vibrates, the former has a higher risk of hitting the hand or head.

Therefore, even when alerting the player by the alert display means, if the same movable body has a plurality of motion modes in the same type of motion, the motion mode that gives a heavy burden to the eyes, or , Movement modes with a high risk of hitting the hand or head (those that may cause injury) have a higher priority for alerting than other movement modes. Therefore, when alerting by the alert display means, the alert regarding the operation mode having a high priority is preferentially displayed, and the operation mode having a low priority is omitted or displayed as a secondary small.

<1-3> When there are a plurality of movable bodies performing the same type of operation In 1-2, a case where there are a plurality of movement modes of the same type in one movable body has been described, but here, the same type of operation is performed. A case where there are a plurality of movable bodies (or effectors) will be described.

For example, when the operation type is "light emission", it is assumed that two or more movable bodies may perform substantially the same light emission operation (high-speed blinking, high-intensity lighting, change from off state to light-emitting state, etc.). A movable body located near the line of sight (for example, a movable body provided on the front side surface side of the game machine frame as in the second operation effect means 47) and a movable body located far from the player's line of sight (for example,). , A movable body provided in the upper part of the game machine frame such as the movable effect means 97, or a movable body provided in the lower part of the game machine frame such as the first operation effect means 46), the former is the eye. The burden on the body is large.

Further, when the movement type is "movable", it is assumed that two or more movable bodies may perform substantially the same movable movement (movement, rotation, vibration), and the movable body moving in the front-rear direction (for example, the second operation). There is a higher risk of the former hitting the head between the effect means 47) and the movable body that moves in the vertical direction (for example, the first operation effect means 46) (comparison when both do not recognize the movement). .. Similarly for rotation and vibration, the risk of pinching your hands or hitting your head depends on the size of the movable body itself and the relationship with the surrounding structures (flat or uneven, etc.). Can be defined.

Therefore, even when the same type of movement is performed by a plurality of movable bodies, those that place a heavy burden on the player have a high priority when the caution display means is used to call the attention. Therefore, the effect operation having a high priority is displayed preferentially, and the effect operation having a low priority is omitted or displayed as a secondary effect.

<2. Attention to game machine installers>
The degree of alerting to the game machine installer is different from that to the player mentioned above. When installing a game machine, of course, the power is not turned on, and the above-mentioned "light emission" and "movable" operations are not performed. The power may be turned on to check the operation after installation, but here, the explanation will be made assuming that the power is not turned on.

<When assembling the parts of 2-1.1>
When assembling one member to the game machine frame, etc., in principle, it is not necessary to call attention to the assembly order, and to call attention to injuries during work of the game machine installer, such as "Be careful of finger pinching!" Is prioritized.

When assembling one member through multiple steps such as moving it up (or down) and then moving it to the left (or right) from that position and fixing it, be careful about the assembly order. Matters may be prioritized, and precautions for injuries during work may be secondary.

<When assembling 2-2-2 or more members in a predetermined order>
When assembling two or more members in a predetermined order for a game machine frame, etc., on the contrary, the priority for calling attention such as "caution for pinching fingers" becomes lower, and each member such as "caution for assembly order!" The priority of calling attention to the assembly order is high. Therefore, the precautions for the assembly order are displayed preferentially, and the precautions such as "caution for pinching fingers" are displayed secondarily.

<3. Warning display means for players and warning display means for game machine installers>

<3-1. Difference in the number of warning display means>
Increase the number of warning display means for the player more than the number of warning display means for the game machine installer. The reason is that since the game machine installer describes the precautions in the "instruction manual", the warning display means placed on the game machine can be suppressed to the minimum necessary, whereas for the player This is because there is only a place to call attention on the game machine, so the number of warning display means required increases. Another reason is that only one type (one action) of attention is given to one warning display means in order to reduce the size of one warning display means so as not to spoil the aesthetic appearance as much as possible. It is also for.

<3-2. Difference in the position of the alert display means>
The warning display means for the player is placed on the front side of the game machine, and the warning display means for the game machine installer is placed on the side of the game machine (upper, left and right, etc.). Further, the warning display means for the game machine installer may be displayed at a position where it can be visually recognized only when the door is opened.

<3-3. Difference in size of alert display means>
The alert display means for the player should not spoil the aesthetics while having the alert power, and the alert display means for the game machine installer emphasizes the alert power rather than the aesthetics. Further, since the warning display means for the game machine installer is in a position invisible (or difficult to see) from the player, one warning display means may have a plurality of different warning targets. The alert items may be displayed, or a plurality of alert items for one alert target may be displayed. For example, the display of "caution for pinching fingers" and the display of "caution for assembly order" are performed by the caution display means such as the printed matter of 1.

<3-4. Difference in display method of alert display>
The warning display means for the player may be a position that can be seen by the player. For example, if it is displayed with a sticker of a type that can be easily peeled off, it may be peeled off intentionally or by mistake. Therefore, various measures such as adopting a seal having higher adhesive strength, coating the surface so that it cannot be touched by hand, and so on can be considered.

On the other hand, the warning display means for the game machine installer is basically only seen by the game machine installer, and once installed, the work of reassembling afterwards does not occur very often, so at least it is a mistake. It is unlikely that it will come off. Therefore, the effect of cost reduction can be expected by adopting a general sticker or the like whose adhesiveness is not so high as compared with the warning display means for the player.

As another countermeasure, the caution display means for the player is covered with a convex portion (not all four sides), or only the caution display area of the caution display means is a concave portion lower than the surrounding. It is also possible to take measures against peeling, such as by setting. In this case as well, the effect of cost reduction can be expected by differentiating according to the person to be alerted, such as not taking the same measures for the alert display to the game machine installer.

As described above, the countermeasure method may be divided according to the person to be alerted, or the countermeasure method may be divided according to the content of the alert (for example, the alert display means for movement is provided with countermeasures to alert the light emission. Measures are not taken for the display means, etc.), and the countermeasures are divided according to the place to call attention (for example, measures are taken for the warning display means displayed in the frame, and measures are taken for the warning display means displayed on the board. No etc.)

The front door 4 is a glass door on the upper side provided with a viewing window 53, a glass unit, etc., and an opening / closing door on the lower side provided with an operation effect means, an upper plate 52, a lower plate 61, a firing handle 63, and the like. It is also possible to divide the glass door into two parts so that the glass door and the opening / closing door can be opened and closed separately around the second hinge means 7 on substantially the same axis.

The liquid crystal substrate case 136 for accommodating the main substrate 137 is arranged side by side, and the main substrate case 138 accommodating the main substrate 137 is arranged on the back side of the ball collecting case 128 below the liquid crystal substrate case 136. The effect board case 134 and the liquid crystal board case 136 are mounted on the back side of the back mounting base 127 and the ball collecting case 128, and the main board case 138 is mounted on the back side of the ball collecting case 128.

As shown in FIGS. 3, 9, 20, and 21, a board mounting base 34 provided with a discharge passage 131 is fixed to the back side of the lower mounting portion 15 of the front frame 3, and the back side of the board mounting base 34 is fixed. The power supply board case 141 for accommodating the power supply board 140 and the payout board case 143 for accommodating the payout board 142 are arranged in front of and behind each other.

Each substrate case 134, 136, 138, 141, 143 is made of transparent resin, and the internal substrates 133, 135, 137, 140, 142 can be visually recognized from the back side. Further, the substrate cases 134, 136, 138, and 143 are protected by a transparent resin back cover 22, and the substrates 133, 135, 137, and 142 can be visually recognized from the back side of the back cover 22. There is.

The back cover 22 is made of colorless transparent or colored transparent synthetic resin, and as shown in FIGS. 3, 8, 9, and 22, the effect substrate case 134 projecting rearward from the back protection portion 14 of the front frame 3. , LCD board case 136, main board case 138, power supply board case 141, payout board case 143, and other back parts are covered from the back side with a flat back surface 144, and the back surface 144 is bent forward along the outer peripheral edge. It is integrally provided with a peripheral edge portion 145 formed on the outer peripheral side to protect back parts such as the effect substrate case 134, the liquid crystal substrate case 136, and the main substrate case 138 from the outer peripheral side. This is to ensure the rigidity of itself and to secure the security for the back parts such as the substrate cases 134, 136, 138, 141, 143 and the like. The back cover 22 is removably attached to the back side of the back protection portion 14 of the front frame 3 by a third hinge means 21 and a latch means 24. A plurality of third hinge means 21 and latch means 24 are provided in the vertical direction.

The back cover 22 secures a predetermined rigidity by integrally providing a peripheral edge portion 145 on the outer peripheral edge of the back surface portion 144. The peripheral edge portion 145 includes bent portions 145a and 145b on both the left and right sides and bent portions 145c and 145d on both the upper and lower sides, and the bending length of the bent portions 145a, 145b, 145c and 145d to the front side is determined by the back protection portion 14 and the like. It is determined by the relative relationship with the mating member, and the bending length is partially different depending on the back protection portion 14 or the like so that the front end side abuts or approaches the back protection portion 14 or the like.

For example, the left and right bent portions 145a and 145b of the peripheral edge portion 145 of the back cover 22 correspond to the magnitude of the amount of protrusion of the attachment portion 20a on one end side and the attachment portion 20b on the other end side of the back protection portion 14 in the rear direction. The bending length of the bent portion 145a on one end side corresponding to the mounting portion 20a on one end side of the back protection portion 14 to the front side is long, and the other end side corresponding to the mounting portion 20b on the other end side of the back protection portion 14 The bending length of the bent portion 145b to the front side is shortened.

As shown in FIG. 3, the peripheral edge portion 145 of the back cover 22 has upper and lower bent portions 145c and 145d in addition to the left and right bent portions 145a and 145b, and the upper bent portions 145c are the ball tank 48 and the guide rail 49. It is inclined substantially parallel to the bottom surface side of the back protection portion 14, and is in contact with the rear end of the upper wall portion 19 of the back protection portion 14. The upper wall portion 19 of the back protection portion 14 has an inclined rear end side on which the upper bent portion 145c of the back cover 22 abuts.

The bent portion 145d on the lower side of the back cover 22 is substantially horizontal and protrudes to the front side to the extent that a predetermined rigidity d of the back cover 22 can be secured. An outside air introduction portion 146 is formed between the lower bent portion 145d and the board mounting base 34, and by introducing outside air from the outside air introduction portion 146 and raising the inside of the back cover 22, it will be described later. It is designed to dissipate heat from heat-generating electronic components. The bent portion 145d on the lower side of the back cover 22 does not have to be substantially horizontal.

As shown in FIGS. 6 and 7, the back cover 22 is in a closed state in which the main board case 138 or the like is covered from the back side in contact with or close to the back side of the back protection portion 14, and the back side of the main board case 138 or the like is opened. It can be opened and closed around the third hinge means 21 in the open state. Further, the back cover 22 can be attached to and detached from the front frame 3 by attaching and detaching the third hinge means 21 up and down in the open state, and the back cover 22 is placed between the back cover 22 side and the front frame 3 side. Regulatory means 149 for restricting attachment / detachment are provided.

As shown in FIGS. 6 and 7, when the back cover 22 is opened from the closed position 22A around the third hinge means 21, the regulating means 149 opens the back cover 22 at an opening angle of less than a predetermined angle α1. Restricts the back cover 22 to be non-detachable, releases the restriction on the back cover 22 when the back cover 22 is opened to a predetermined angle α1 or more and is located at the detachable position 22B, and separates the third hinge means 21 vertically. The back cover 22 can be removed from the game machine main bodies 2 and 3.

As shown in FIGS. 23 to 26, the regulating means 149 is arranged at the upper bent portion 145c of the back cover 22 and the guide rail 49 arranged near the upper side of the back cover 22 and projecting rearward from the back cover 22. It is composed of and. When the back cover 22 is less than the predetermined angle α1, the bent portion 145c of the back cover 22 is under the guide rail 49 to restrict the back cover 22 from being detachable, and the back cover 22 has the predetermined angle α1. When the back cover 22 is opened and located at the attachment / detachment position 22B, the bent portion 145c of the back cover 22 retracts rearward from the guide rail 49 to release the restriction on the back cover 22.

The back cover 22 has a structure in which a flat back surface portion 144 and a peripheral edge portion 145 that bends from the outer circumference of the back surface portion 144 to the front side are integrally provided, and the back surface portion 144 is simply a substrate case 134, 136, 138. In addition to covering the back parts such as 141 and 143 from the back side, the back parts such as the board case 134 are protected from the outer peripheral side by the peripheral edge portion 145 that bends from the outer peripheral side of the back surface portion 144 to the front side to ensure security. ing.

Therefore, when the back cover 22 is opened to a predetermined angle α1 or more and is located at the attachment / detachment position 22B, the upper side of the peripheral edge portion 145 of the back cover 22 is retracted to a position where it is displaced rearward from the guide rail 49, and the peripheral edge of the back cover 22 is retracted. The lower side of the portion 145 is retracted to a position where it can be detached rearward from the back component such as the board case 134, so that the peripheral edge portion 145 does not interfere with the back mechanism even if the back cover 22 is moved upward.

Therefore, when removing the back cover 22, after releasing the latch means 24, the back cover 22 is moved around the third hinge means 21 until the upper bent portion 145c of the back cover 22 comes off from the guide rail 49 rearward. The back cover 22 may be lifted to the rear at a predetermined angle α1 or more, and the third hinge means 21 may be separated into upper and lower parts and pulled out.

The reason is that even if the back cover 22 is opened around the third hinge means 21, if the back cover 22 is less than the predetermined angle α1, even if the back cover 22 is lifted, it is under the guide rail 49 and is on the back. The upper bent portion 145c of the cover 22 comes into contact with the lower surface side of the guide rail 49, and the regulating means 149 restricts the removal of the back cover 22. Therefore, the back cover 22 is lifted until the third hinge means 21 is separated vertically. Can't.

If the back cover 22 is opened to a predetermined angle α1 or more and is located rearward from the attachment / detachment position 22B, the back cover 22 will come off rearward from the rear end of the guide rail 49, and even if the back cover 22 is lifted, the guide rail 49 Since it does not hit the lower side and the regulation of the regulating means 149 on the back cover 22 can be released, the back cover 22 can be removed. When the back cover 22 is attached, the reverse operation is performed.

In this way, when the opening angle of the back cover 22 is less than the predetermined angle α1, the regulation means 149 restricts the removal of the back cover 22, and when the back cover 22 is opened by the predetermined angle α1 or more, the regulating means 149 regulates the removal. The regulation of the back cover 22 is released so that the back cover 22 can be removed. As a result, when the back cover 22 is removed, it is possible to prevent interference with back parts such as the effect board case 134, the liquid crystal board case 136, and the payout board case 143 of the peripheral portion 145. Further, since the guide rail 49 is used as the regulating means 149, the structure can be simplified as compared with the case where the dedicated regulating means is provided.

When the back side mechanism 17 of the main board case 138 or the like is maintained / inspected with the game machine 1 mounted on the island facility 150 of the game hall, the front frame 3 is as shown in FIG. 26-1. It is necessary to open the back cover 22 around the first hinge means 6 and wrap around the back side of the front frame 3 in that state by opening the back cover 22 around the third hinge means 21.

In this case, as shown in FIG. 21, if the first hinge means 6 that supports the front frame 3 and the third hinge means 21 that supports the back cover 22 are on opposite sides, the back side mechanism 17 is on the front side. Since there is a cover 22, a worker enters between the back cover 22 and the island facility 150 to perform maintenance / inspection work. This also applies when the illicit worker removes the main board case 138 and performs the illicit work, and the illicit worker gets in between the back cover 22 and the island equipment 150 which are in the open state as at the time of inspection. There is a need. Therefore, if the back cover 22 is opened, it becomes very noticeable, so that there is an advantage that it is possible to prevent an illegal work performed by opening the back cover 22, such as an illegal work on the main board 137.

The bent portion 145b on the other end side of the back cover 22 is fixed to the mounting portion 20b of the side wall portion 18 of the back protection portion 14 by the latch means 24 arranged at the contact portions 152 on both the upper and lower end sides thereof. The latch means 24 is a push-pull type, and as shown in FIGS. 27 and 28, it is arranged in the contact portion 152 of the bent portion 145b of the back cover 22 and in the mounting hole 153 of the mounting portion 20b of the back protection portion 14. It includes an engaging body 154 that engages with each other so as to be engaged and disengaged from the inner peripheral side, and an operating body 155 that is inserted into the engaging body 154 so that it can be pushed and pulled.

The engaging body 154 includes a body portion 157 inserted into the through hole 156 of the contact portion 152, a collar portion 158 formed on the rear end side of the body portion 157 and abutting on the back surface of the contact portion 152, and a body portion 157. It is provided on the front end side of the mounting hole 153 so as to be expandable and contractible, and has a plurality of engaging claws 159 in the circumferential direction in which the outer peripheral surface engages with the front side of the mounting hole 153 when expanded.

The operating body 155 is a push-pull that is provided on the rear end side of the operating shaft portion 160 inserted through the body portion 157 and the flange portion 158 of the engaging body 154 and the operating shaft portion 160 and is capable of contacting the back surface of the flange portion 158. When the operation unit 161 and the operation unit 161 provided at the front end of the operation shaft unit 160 and the operation unit 161 are pushed to the pushing position 161A, the engaging claw 159 is expanded outward and the operation part 161 is pulled out to the pull-out position 161B. It sometimes has a scaling portion 162 that shrinks the engaging claw 159 inward. The operating body 155 does not fall off from the engaging body 154.

As shown in FIG. 27, when the operating body 155 is pushed to the pushing position 161A, the rear end of the operating portion 161 is located in front of the back surface of the back surface portion 144 of the back cover 22. Further, when the operating body 155 is pulled out to the pull-out position 161B, the rear end of the operating portion 161 is substantially the same height as the back surface of the back surface portion 144 of the back cover 22, or slightly lower than the back surface of the back surface portion 144. ..

When the bent portion 145b of the back cover 22 is fixed to the attachment portion 20b of the back protection portion 14 by the latch means 24, the procedure is as follows. If the operating body 155 of the latch means 24 is pulled out to the pull-out position 161B, when the engaging claw 159 is inserted into the mounting hole 153 of the mounting portion 20b, the engaging claw 159 is pressed against the inner circumference of the mounting hole 153. The engaging claw 159 of the engaging body 154 is inserted into the mounting hole 153. As a result, the bent portion 145b of the back cover 22 can be fixed to the mounting portion 20b of the back protection portion 14 by the latch means 24.

When the engaging claw 159 is pierced into the mounting hole 153 of the mounting portion 20b, the contact portion 152 of the back cover 22 comes into contact with the back surface of the mounting portion 20b, so that the operating portion 161 of the operating body 155 is pushed forward to the pushing position 161A. Push it in. At this time, since the expansion / contraction portion 162 of the operating body 155 expands the engaging claw 159 to the outside, the outer peripheral side of the engaging claw 159 is pressure-welded to the inner circumference of the mounting hole 153 of the mounting portion 20b, as shown by a solid line in FIG. Then, the engaging body 154 connects the bent portion 145b of the back cover 22 and the mounting portion 20b of the back protection portion 14 back and forth. As a result, the bent portion 145b of the back cover 22 can be fixed to the mounting portion 20b of the back protection portion 14 by the latch means 24.

When the operating body 155 is pushed to the pushing position 161A, the rear end of the operating portion 161 is on the front side of the back surface of the back surface portion 144 of the back cover 22, and the rear end of the operating unit 161 with respect to the back surface portion 144 of the back cover 22. Is recessed so that the latching means 24 does not interfere with anything else.

When opening and closing the back cover 22, first, the fixing by the latch means 24 is released. In that case, the operation unit 161 of the operation body 155 is grasped by the fingers, and the operation body 155 is pulled out to the pull-out position 161B. Then, the expansion / contraction portion 162 of the operating body 155 is disengaged from the engaging claw 159. Therefore, if the bent portion 145b side of the back cover 22 is pulled backward, the engaging claw 159 is disengaged from the mounting hole 153 of the mounting portion 20b, and the latch means 24 The fixing of the effect board case 134 can be released.

That is, when the operating body 155 is pulled out to the pull-out position 161B, the expansion / contraction portion 162 is disengaged from the engaging claw 159, so that the engaging claw 159 has its own elastic force or the elasticity of the joint portion between the engaging claw 159 and the body portion 157. It contracts inward by force, or the engaging claw 159 can be elastically deformed inward. Therefore, when the operating portion 161 is pulled further rearward, as shown in FIG. 28, the engaging claw 159 of the engaging body 154 comes out rearward from the mounting hole 153 of the mounting portion 20b, so that the fixing by the latch means 24 is fixed. It can be released.

When the operating body 155 of the latch means 24 is pulled out to the rearward position 161B, the rear end of the operating body 161 of the operating body 155 is substantially the same height as the back surface of the back surface portion 144 of the back cover 22, or the back surface portion 144. Since the operation unit 161 is slightly lower than the back surface of the back cover 22, the operation unit 161 does not get in the way as compared with the one protruding from the back surface of the back surface portion 144 of the back cover 22.

A plurality of three third hinge means 21 are provided in the vertical direction, and as shown in FIGS. 29 to 34, the hinge shaft 147 provided integrally with the bent portion 145a side on one end side of the back cover 22 and A hinge bearing 148 is provided integrally with the side wall portion 18a on one end side of the back protection portion 14 which is a support member and receives the hinge shaft 147, and the hinge shaft 147 is determined to be located on the vertical axis center in the vertical direction. Multiple pieces are arranged in the vertical direction with an interval of.

The outer peripheral surface of the hinge shaft 147 has a substantially cylindrical surface shape, has a diameter sufficiently larger than the plate thickness of other parts of the back cover 22, and projects downward to the lower side of the support base portion 165. The hinge shaft 147 is provided with a tapered insertion head 166 on the lower end side, and a recess 167 having a substantially U-shaped cross section between the insertion head 166 and the support base 165. There is. The recess 167 is recessed in the radial direction from the front surface side of the hinge shaft 147, and is formed long in the vertical axial direction between the insertion head 166 and the support base 165.

Therefore, the hinge shaft 147 has an elliptical shape in which the major axis portion 147A and the minor axis portion 147B are arranged in substantially perpendicular directions, and the open end of the recess 167 is located on one end side of the minor axis portion 147B. .. The hinge shaft 147 has a recess 167 open to the front side.

The support base portion 165 is integrally provided on the front end side of the bent portion 145a, and the base wall 165a projecting outward from the bent portion 145a and a pair of upper and lower semicircular support walls protruding outward from the base wall 165a. It has a 165b and a connecting wall 165c that is arranged substantially at right angles to the base wall 165a and connects the upper and lower support walls 165b in the vertical direction.

The wall thickness can be made thin. Therefore, even if the diameter of the hinge shaft 147 is sufficiently secured, the wall thickness can be suppressed to about the plate thickness of the back cover 22, and the curing speed of the molten resin on the hinge shaft 147 side at the time of injection molding is slow. Therefore, it is possible to prevent molding distortion from occurring.

Further, when the back cover 22 is molded, the back cover 22 remains on the movable mold side and is pushed out from the front side by the extruded portion on the movable mold side, but the recess 167 is recessed from the front side to the rear side. Therefore, the hinge shaft 147 can be molded in the same manner as the normal injection molding of the back cover 22.

Therefore, when the first case body 218 is molded, it is molded by injection molding in which the molten resin is poured into the cavity of the molding die from the three resin pouring portions corresponding to the traces of each resin pouring portion 217.

When molten resin is poured from the three resin pouring portions and molded, a short weld line 216a is formed downstream of the heat radiating holes 214 on the heat radiating hole 214 side located near each resin pouring portion. On the other hand, even between the three resin pouring portions, a relatively long weld line is connected to the intermediate portion between the adjacent resin pouring portions so as to connect a plurality of heat dissipation holes 214 in the direction connecting the two resin pouring portions and in the direction intersecting with each other. 216b can be made. This is the same as in the case of the main board case 138.

Even if weld lines 216a and 216b are generated on the rear wall portion 218a of the first case body 218 in this way, the weld lines 216a and 216b are located at positions deviated from the specific portion on the liquid crystal substrate 135 side. The 216a and 216b do not reduce the visibility of the specific portion on the liquid crystal substrate 135 side.

In this embodiment, there is a part of the integrated circuit device 210 in the formation region 215 of the heat radiating hole 214, but the heat radiating hole 214 may be provided so as not to overlap with each integrated circuit device 210. Further, although the resin pouring portion trace 217 overlaps with the integrated circuit device 210, it is desirable that the resin pouring portion trace 217 does not overlap with the integrated circuit device 210.

When comparing the importance of the main board 137 housed in the main board case 138 and the sub-boards such as the effect board 133 housed in the effect board case 134 and the liquid crystal board 135 housed in the liquid crystal board case 136 in the game machine 1. The importance of the main board 137 (first board), which determines the game content of the game machine 1 itself, is compared with the sub-boards (second board) such as the effect board 133 and the liquid crystal board 135, which simply control the effect operation. It's much bigger. Therefore, the main board case 138 (first board case) for accommodating the main board 137 is required to have higher strength than the effect board case 134 (second board case) for accommodating the effect board 133, and at the same time, it is inside. High visibility is required for a specific part of the.

On the other hand, when the main substrate case 138, the effect substrate case 134, and the like are molded with resin, if the number of resin pouring portions is increased, there is an advantage that the cycle time required for molding the respective substrate cases 138 and 134 can be shortened and the production can be performed efficiently. On the other hand, there is a problem that the number of traces of the resin pouring portion 192,207 increases and the visibility inside is lowered. Further, if the number of the resin pouring portion traces 192, 207 increases, the number of weld lines 192a, 192b, 208a, 208b formed between the resin pouring portions also increases, so that the weld lines 192a, 192b, 208a, 208b increase. As a result, the visibility inside the substrate cases 138 and 134 is lowered, and at the same time, the strength of the substrate cases 138 and 134 itself is also lowered.

Therefore, regardless of whether the volume of the synthetic resin portion of the main board case 138 and the sub-board case such as the effect board case 134 is substantially the same, or whether the volume of the main board case 138 is larger or smaller than that of the sub-board case. Do the following: For example, the number of resin pouring portion traces (or resin pouring portion) 192 of the first case body 180 of the main board case 138 is N2 (N2 ≧ 1), and the number of sub-boards such as the first case body 201 of the effect board case 134 is set. The number of resin pouring portion traces (or resin pouring portion) 207 on the case side is N2 + n2 (n2 ≧ 0). As a result, the strength and visibility of the main board case 138 side can be improved as compared with the effect board case 134 side.

Incidentally, in this embodiment, the number N2 of the resin pouring portion trace 192 of the first case body 180 of the main substrate case 138 is set to two, and the number N2 + n2 of the resin pouring portion trace 207 of the first case body 201 of the effect board case 134. It is one less than the three of.

The main board case 138 and the second case body 181, 202 side of the effect board case 134 are both flat, and in order to correspond to the back surface side of the boards 133 and 137 itself, the resin pouring portion trace (or the resin pouring portion) ) May be the same number, but may be the same as the resin pouring portion trace (or resin pouring portion) on the first case body 180, 201 side.

A window 268 and a viewing window 269 corresponding to the opening history notation means 246 are provided.

The operation holes 265 and 266 have tubular portions 265a and 266a projecting forward from the back surface portion 144, and when operating the operation means 176 and the game information clearing means 236, the back cover 22 is kept closed. A fingertip or other object is inserted into the tubular portions 265a and 266a of the operation holes 265 and 266 from the back side of the cover 22, and operations such as pressing the operation means 176 and the game information clearing means 236 are performed.

The viewing windows 267 and 269 for the opening history notation means 184 and 246 are formed corresponding to the substrate cases 138 and 143 of the back portion 144 of the back cover 22, and the back cover 22 is kept closed. From the back side of 22, the notation information of the opening history notation units 191 and 249 of the opening history notation means 184 and 246 can be easily read. Therefore, it is not necessary to open and close the back cover 22 each time the notation information of the opening history notation means 184 and 246 is confirmed.

Since the back cover 22 is a molded product of transparent resin, it is also possible to confirm the notation information of the management information notation units 178 and 239 and the part information display units 179 and 240 via the back surface portion 144 of the back cover 22. Yes, it is not always necessary to provide an opening-shaped viewing window corresponding to the management information notation units 178,239 and the part information display units 179,240.

The back surface portion 144 of the back cover 22 can confirm the error information displayed on the payout error display means 237 from the back side of the back cover 22 in the closed state. Further, the back surface portion 144 of the back cover 22 is provided with a viewing window 268 in an opening shape corresponding to the error information display means 245, and the display information of the error information display means 245 can be visually recognized from the viewing window 268. ..

Therefore, by looking at the error information of the payout error display means 237 in the payout board case 143 from the back side of the back cover 22, the location where the error of the payout means 23 occurs can be easily confirmed.

If the location where the error has occurred cannot be determined only by displaying the error information of the payout error display means 237, the location where the error has occurred can be easily confirmed by collating with the display information of the error information display means 245 through the viewing window 268. can do.

The heat radiating holes 264 are centrally provided in the upper portion 22U of the back surface portion 144 of the back cover 22. The back portion 144 of the back cover 22 is substantially divided into an upper portion 22U corresponding to the effect substrate case 134 and the liquid crystal substrate case 136, and a lower portion 22D corresponding to the main substrate case 138, the power supply substrate case 141, and the payout substrate case 143. It can be divided into two. Therefore, when the distribution status of the heat radiating holes 264 is compared by dividing the upper portion 22U and the lower portion 22D, the heat radiating holes 264 are arranged substantially evenly over the entire upper portion 22U, and the lower side. Not provided in portion 22D. Each heat radiating hole 264 has an elongated shape long in the left-right direction, and is arranged at a predetermined interval between the heat radiating holes 264 adjacent to each other in the left-right direction and the up-down direction.

The heat dissipation hole 264 of the back cover 22 is not arranged in the vicinity of the operation shaft 196a of the volume adjusting means 196, and the volume adjusting means 196 is operated by inserting a tool such as a screwdriver from the heat dissipation hole 264. The shaft 196a cannot be operated. Therefore, the operating means 176 and the game information clearing means 236 can be operated from the back side of the back cover 22 in a closed state without opening the back cover 22, but the volume adjusting means 196 cannot be operated unless the back cover 22 is opened. .. This is because the volume adjusting means 196 is operated less frequently than the operation means 176 and the game information clearing means 236.

In providing the heat dissipation holes 264 on the back surface portion 144 of the back cover 22 in this way, by arranging the heat dissipation holes 264 substantially evenly over the entire area of the upper portion 22U thereof, the high temperature that tends to stay on the upper side in the back cover 22 is high. Air can be discharged to the outside through the heat dissipation hole 264. Therefore, air convection is generated in the back cover 22, and external cold air can be introduced from the outside air introduction portion 146 on the lower end side of the back cover 22, and high-temperature hot air can be discharged from the heat radiation hole 264 at the upper part. It is possible to efficiently dissipate heat via 264.

Further, among the back surface portions 144 of the back cover 22, the lower portion 22D corresponding to the main substrate case 138 and the payout substrate case 143 is provided with operation holes 265 and 266 and viewing windows 267 to 269, and is on the lower side. Since the heat radiation hole 264 and other openings are not provided in substantially the entire area of the portion 22D, the status of the main board 137 and the payout board 142 inside the main board case 138 and the payout board case 143 from the back side of the back cover 22. Can be easily visually recognized, and deterioration of visibility of the main substrate 137 and the payout substrate 142 with respect to a specific portion can be prevented.

Moreover, since the lower portion 22D of the back surface portion 144 of the back cover 22 is in a non-perforated state with no openings other than the operation holes 265 and 266 and the viewing windows 267 to 269, the lower portion 22D of the back surface portion 144 is opened. It is possible to promote the ascending flow of air on the lower side in the back cover 22 as compared with the case where there is. Therefore, the convection of air in the back cover 22 can be further promoted.

Since the heat radiating holes 264 have a long hole shape that is long in the left-right direction, it is possible to increase the opening area of each heat radiating hole 264 as compared with the case of the round hole shape, and reduce the number of heat radiating holes 264. can do.

Further, the harness 255 that curves in a U shape to the back side between the connectors 177a and 197a that are close to each other in the vertical direction, such as the connector 177a of the main board 137 and the connector 197a of the effect board 133, with a predetermined margin. When connecting vertically, the harness 255 in the vertical direction may come into contact with or press contact with the inside of the back surface portion 144 of the back cover 22.

Even in such a case, by forming the heat dissipation hole 264 in the shape of a long hole in the left-right direction, the heat dissipation hole 264 is in the left-right direction with respect to the harness 255 in the vertical direction, so that a part of the harness 255 is formed from the heat dissipation hole 264. It does not come out on the back side of the back cover 22.

Further, the harness 258 for connecting the connector 197b of the effect board 133 and the connector 211a of the liquid crystal board 135 is arranged in the left-right direction, but the distance between the two connectors 197b and 211a in the left-right direction is the vertical distance between the connectors 177a and 197a. Since it is sufficiently large in comparison, the length of the harness 258 in the left-right direction becomes long, and it is not necessary to bend or bend it extremely as compared with the harness 255 between the connectors 177a and 197a. Unless it becomes extremely long, the harness 258 does not protrude from the heat radiation hole 264 to the back side of the back cover 22.

As shown in FIGS. 3, 41, and 42, a plurality of resin pouring portion traces 280 and extruded portion traces 281 are formed on the back surface portion 144 of the back cover 22 at positions deviating from specific portions of the respective substrates 133 and 137. is there. The resin pouring portion trace 280 indicates a trace of the resin pouring portion in which the molten resin is poured into the cavity of the molding mold at the time of molding the back cover 22, and is substantially covered in the entire cavity of the molding mold within a predetermined time. The molten resin is dispersed and arranged so that the molten resin can be poured evenly.

In the upper portion 22U in which a large number of heat radiating holes 264 are arranged, a large number of heat radiating hole molded portions of the mold act as a flow inhibiting portion for the molten resin, so that the flow resistance when the molten resin flows in the cavity is large. Therefore, it is necessary to pour the molten resin from the resin pouring portion against the flow resistance. Therefore, when the back cover 22 is molded, the upper portion 22U has many resin pouring portions, and as a result, the upper portion 22U of the back cover 22 has many resin pouring portion traces 280. A plurality of traces of the resin pouring portion 280, for example, N3, are provided from the intermediate portion to the peripheral portion of the formation region 282 of the heat radiation hole 264.

The upper portion 22U of the back cover 22 has a large number of heat dissipation holes 264, and an extrusion resistance is generated between the large number of heat dissipation hole molded portions of the mold and the heat dissipation hole 264, and an extrusion resistance is generated at the peripheral edge portion 145. There are far more extruded portion traces 281a and 281b than the number of resin poured portion traces 280.

As shown in FIGS. 43 and 44, the resin pouring portion trace 280 is arranged outside the back surface portion 144 of the back cover 22. On the other hand, the extruded portion trace 281a has a circular shape and is arranged on the front side of the back surface portion 144 of the back cover 22, and the extruded portion trace 281b has a semicircular shape and is arranged at the front end of the peripheral edge portion 145.

Further, in the lower portion 22D in which the operation holes 265 and 266 and the viewing windows 267 to 269 are almost non-perforated to some extent, the flow resistance when the molten resin flows in the cavity is smaller than that in the upper portion 22U. Since the molten resin circulates quickly in the cavity, the number of traces of the resin pouring portion 280 is smaller than that of the upper portion 22U.

Moreover, in the lower portion 22D, the main substrate case 138 and the payout substrate case are not impaired by the resin pouring portion trace 280 and the weld line 283 generated during molding so as not to impair the visibility of specific parts of the main substrate 137 and the payout substrate 142. In the vicinity of the outer circumference of 143, there are a relatively small number of resin pouring traces 280.

That is, the number of resin pouring portion traces 280 of the lower portion 22D of the back cover 22 is N3-n3 (N3> n3 ≧ 1), and 2 on the upper portion 22U side located near the upper side of the main substrate case 138. Even if the traces of the resin pouring portion 280 are included, the number is as small as four, one between the main board case 138 and the payout board case 143 and one at the outer position of the payout board case 143. ..

It should be noted that the resin molding part and weld line 283 such as the resin pouring part trace 280 of the lower portion 22D of the back cover 22, and the resin molding part and weld such as the resin pouring part trace 192 and 252 of the main substrate case 138 and the payout case 143. The lines 192a, 192b, 251a, and 251b are designed so that they do not overlap each other with respect to specific parts of the main substrate 137 and the payout substrate 142 even if they overlap each other in the front-rear direction.

The entire back cover 22 is divided into a hinge side portion 22L on the first hinge means 6 side and an anti-hinge side portion 22R on the opposite side to the first hinge means 6 with the center line CL1 as a boundary, and the traces of the resin pouring portions of both are divided. When comparing the number NX of 280, the number NR of the resin pouring portion 280 of the anti-hinge side portion 22R having a large volume is larger than the number NL of the resin pouring portion 280 of the hinge side portion 22L having a small volume.

This is because the bending length of the bending portion 145a to the front side of the peripheral edge portion 145 of the back cover 22 is longer than the bending length of the bending portion 145b to the front side, and the anti-hinge side portion 22R of the back cover 22. This is because the volume is larger than the volume of the hinge side portion 22L. As a result, when the back cover 22 is molded, the molten resin can be poured substantially evenly in a short time into the cavity of the anti-hinge side portion 22R of the mold and the cavity of the hinge side portion 22L.

Incidentally, the number NL of the resin pouring portion trace 280 of the anti-hinge side portion 22R of the back cover 22 is 4, and the number NR of the resin pouring portion trace 280 of the hinge side portion 22L is 3. The number of traces of the resin pouring portion 280, NL = 4, and NR = 3, is merely an example.

Five resin-filled traces 280 of the anti-hinge side portion 22R are dispersed in the vicinity of the bent portion 145c and the central side of the back surface portion 144, and are arranged in the vertical direction. Further, the resin pouring portion trace 280 of the hinge side portion 22L is arranged in the back surface portion 144 in the vicinity of the bending portions 145b, 145c, 145d in the vertical direction. Therefore, it is possible to improve the circulation of the molten resin from the outer peripheral portion 145 side to the cavity on the back surface portion 144 side in the vicinity thereof.

The resin pouring portion trace 280 of the hinge side portion 22L is in the vicinity of the bent portions 145b, 145c, 145d, but there is only the resin pouring portion trace 280 on the left-right central side of the back portion 144, and the hinge side portion. There is no resin pouring portion trace 280 on the left and right center side of 22L. This is because the molten resin in the cavity in the central portion of the back surface portion 144 has good circulation.

Even when the molten resin is poured into the back surface portion 144 of the back cover 22 from the resin pouring portion corresponding to the resin pouring portion trace 280, the integrated circuit devices 174,195,210 on the respective substrates 133, 135, 137, 142 sides. , 235, parts information display units 179, 199, 212, 240, board management information display units 178, 200, 213, 239, etc., so that weld lines 283 do not occur corresponding to specific parts, each board 133, 135, There are traces of the resin pouring portion 192, 207, 217, 252 at a position deviated from the specific portion on the 137, 142 side.

At the time of injection molding of the back cover 22, molten resin is poured into the cavity of the molding die from the resin pouring portion corresponding to each resin pouring portion trace 280 and molded. In this case, on the opening side of the heat dissipation hole 264 or the like, a short weld line (not shown) is formed on the downstream side of each heat dissipation hole 264 on the side close to each resin pouring portion due to the merging of the molten resin poured from the resin pouring portion. Further, in the intermediate portion between the two adjacent resin pouring portions, a long weld line 283 due to the merging of the molten resin from the two resin pouring portions can be formed to connect the plurality of heat radiating holes 264.

The resin pouring portion trace 280 is positioned so as to sandwich the formation region 282 of the heat dissipation hole 264 at a predetermined interval, and when the back cover 22 is molded, two resin pouring portions corresponding to the resin pouring portion trace 280 are formed. It is molded by pouring molten resin into the cavity of the molding mold from the part.

When the back cover 22 is molded by pouring molten resin from the two resin pouring portions corresponding to the resin pouring portion traces 280, the back portion 144 is on the downstream side of approximately half of the heat dissipation holes 264 on the side close to each resin pouring portion. A weld line (not shown) is formed by merging the molten resin poured from the resin pouring portion, and a weld line is formed by merging the molten resin from the two resin pouring portions in the substantially central portion between the two resin pouring portions. The 283 can be made to connect the plurality of heat dissipation holes 264.

The former weld line can be shortened to the downstream side of each heat dissipation hole 264, but the latter weld line 283 can be lengthened so as to connect a plurality of heat dissipation holes 264 in the direction intersecting the diagonal direction corresponding to the resin pouring portion. Or, it can be lengthened at a position separated from between the two resin pouring portions in a direction intersecting the diagonal direction.

Such a weld line 283 causes an extremely decrease in the tensile strength of the back surface portion 144 of the back cover 22, and also causes the back side of the back cover 22 to pass through the back surface portion 144 of the substrates 133, 135, 137, respectively. This is a factor that hinders visibility when visually recognizing a specific portion on the 142 side. However, by considering the arrangement position of the resin pouring portion, it is possible to prevent the weld line 283 generated on the back surface portion 144 of the back cover 22 from overlapping with the specific portion on each substrate 133, 135, 137, 142 side. The visibility is not hindered by the weld line 283.

For example, looking at the positional relationship between each resin pouring portion trace 280 and each weld line 283 of the back cover 22, the upper portion 22U of the back portion 144 is as shown in FIG. 41, and the lower portion 22D of the back portion 144 is shown in FIG. It is as shown in 42.

That is, on the upper side portion 22U side of the back surface portion 144, as shown in FIG. 41, a weld line c is provided between the resin pouring portion trace a and the resin pouring portion trace b, and the resin pouring portion trace a and the resin pouring portion trace d are provided. There is a weld line e between the resin pouring portion b, a weld line f between the resin pouring portion trace b and the resin pouring portion trace d, and a weld line h between the resin pouring portion trace d and the resin pouring portion trace g. A weld line s is provided between the pouring portion a and the resin pouring portion g, a weld line j is provided between the resin pouring portion d and the resin pouring portion i, and the resin pouring portion b and the resin pouring portion trace i are provided. Weld lines k are generated between and each.

Each weld line 283 on the upper portion 22U side is generated at a position deviated from specific parts such as the component information display units 199 and 212 of the effect board 133 and the liquid crystal board 135 and the board management information display units 200 and 213. Therefore, the resin pouring traces 207 and 217 and the weld lines 208b and 216b on the rear wall portions 201a and 218a of the substrate cases 134 and 136 are the component information display portions 199 and 212 of the effect substrate 133 and the liquid crystal substrate 135, and the substrate management information display. Although there are a large number of heat dissipation holes 264 on the back surface portion 144 of the weld line 283, the visibility of the specific portion is hindered by the weld line 283 and the like, in combination with the fact that the portions 200 and 213 are separated from the specific portion. There is nothing.

In the lower portion 22D of the back surface portion 144, as shown in FIG. 42, a weld line m is formed between the resin pouring portion trace g and the resin pouring portion trace l, and the resin pouring portion trace d and the resin pouring portion trace l are formed. There is a weld line n between the resin pouring portion trace i and the resin pouring portion trace l, a weld line o between the resin pouring portion trace i and the resin pouring portion trace l, and a weld line q between the resin pouring portion trace i and the resin pouring portion trace p. Weld lines r are generated between the trace l and the trace p of the resin pouring portion, respectively.

Each weld line 283 of the lower portion 22D is generated at a position deviated from specific parts such as the component information display units 179 and 240 and the board management information display units 178 and 239 of the main board 137 and the payout board 142. Therefore, the traces of the resin pouring portion 280 and the weld line 283 on the rear wall portions 180a and 241a of the substrate cases 138 and 143 are the component information display portions 179 and 240 and the substrate management information display units 178 and 239 of the main substrate 137 and the payout substrate 142. The visibility of the specific part is not impaired by the weld line or the like in combination with the fact that the part is out of the specific part such as. Further, since the back surface portion 144 of the back cover 22 does not have heat dissipation holes or the like corresponding to the main board case 138 and the payout board case 143, there are a large number of heat dissipation holes 204 and 214 on the effect board 133 side and the liquid crystal board 135 side. Visibility is further improved in comparison.

At the time of injection molding of the back cover 22, molten resin is poured into a cavity between a protruding movable mold and a recessed fixed mold for molding. After the resin is cured, the movable mold is opened to be separated from the fixed mold, and the molded product for the back cover 22 remaining on the movable mold side is extruded by an extrusion portion such as an extrusion pin on the movable mold side.

The extruded portion traces 281a and 281b are traces of the extruded portion being brought into contact with the molded product at the time of die cutting, and the movable mold has the back portion 144 and the peripheral portion 145 in consideration of the extrusion resistance of each portion of the back cover 22. A large number of extruded portions are provided so as to correspond to the above, and a large number of extruded portion traces 281a and 281b remain on the back surface portion 144 and the peripheral edge portion 145 of the back cover 22.

The extruded portion trace 281a of the back surface portion 144 of the back cover 22 has a round shape, and the extruded portion trace 281b of the peripheral portion 145 has a semicircular shape, and the shape differs depending on the conditions of the target portion. On the upper side of the back surface portion 144 of the back cover 22, a large number of extruded portion traces 281a are arranged between the heat radiation holes 264 so as to be substantially evenly distributed over the entire area of the heat radiation hole 264 forming region 282. Further, on the lower side of the back surface portion 144 of the back cover 22, the peripheral portion of the main substrate case 138 and the peripheral portion of the payout substrate case 143 are arranged corresponding to the peripheral portion. On the payout substrate case 143 side, the extruded portion trace 281a is arranged at the peripheral portions such as the four corners of the viewing window 268 for the error display portion of the payout substrate 142.

Therefore, the upper portion 22U of the back surface portion 144 of the back cover 22 has a large number of heat dissipation holes 264, which is structurally complicated and has a large extrusion resistance, but a large number of heat dissipation holes 264 are formed in substantially the entire area 282. Since there is an extruded portion trace 281a, the extruded portion corresponding to each extruded portion trace 281a can sufficiently resist the extruding resistance of the back cover 22.

On the other hand, the lower portion 22D of the back portion 144 of the back cover 22 has no heat radiating holes 264 or the like and has a flat spread compared to the upper side and the extrusion resistance is small, so that the number of extrusion portion traces 281a and 281b is large. It is less than the upper side. Further, in the lower portion 22D of the back cover 22, it is important to ensure visibility of the main board 137 and the payout board 142. Therefore, the overlap of the extruded portion traces 281a and 281b with respect to the main board 137 and the payout board 142 is minimized. A small number of extruded portion traces 281a and 281b are arranged around the main board case 138 and the payout board case 143. Therefore, the lower portion 22D of the back cover 22 can be easily extruded from the mold without impairing the visibility of the back cover 22 with respect to the main substrate 137 and the payout substrate 142.

The extruded portion traces 281b of the peripheral edge portion 145 of the back cover 22 are arranged on the front end surface of the peripheral edge portion 145 at predetermined intervals along the longitudinal direction thereof. Therefore, when the back cover 22 is die-cut, the front end surface of the peripheral edge portion 145 is pressed in the pushing direction by the extruded portion, so that the peripheral edge portion 145 can be reliably removed from the movable mold.

In this type of gaming machine 1, molded products such as the main substrate case 138 and the payout substrate case 143 are manufactured by an injection molding method in which molten resin is poured into a cavity from a resin pouring portion of a mold. Therefore, if the number of resin pouring portions is increased, it is possible to quickly pour the molten resin into the cavity, the cycle time at the time of molding the molded product can be shortened, and there is an advantage that efficient production can be performed.

However, if the number of resin pouring portions increases in the molded product after molding, resin pouring portion traces 192 and 252 corresponding to the number of resin pouring portions are formed, and weld lines 192a, 192b, 251a and 251b are generated. .. Then, the traces of the resin pouring portion 192,252 and the weld lines 192a, 192b, 251a, 251b are important specific portions such as the substrate management information display portions 178, 239 displayed on the substrates 137, 142 in the substrate cases 138, 143. In the case of corresponding to the above, the visibility with respect to the specific portion is lowered, and the mechanical strength of the substrate cases 138 and 143 is lowered regardless of whether or not the specific portion is supported.

That is, in resin molding, injection molding is a molding method capable of mass-producing molded products having complicated shapes in one process, and the molding process follows the processes of melting, transferring, cooling, and solidifying. The traces of the resin pouring portion 192 and 252 are traces of the trace of the resin pouring portion in which the molten resin is poured into the cavity of the mold, and the traces of the resin pouring portion 192 and 252 reduce the visibility to a specific part inside due to diffused reflection of light. There is a problem to do.

The weld lines 192a, 192b, 251a, and 251b are phenomena that occur when molten resin is poured into the cavity from the resin pouring portion and when a molded product having holes and openings is molded, and the melt is divided into two hands in the cavity. When the resins merge again, the surface of the molten resin at the merged portion is slightly lowered and hardened, so that the resin is generated in a line shape. Then, in the case of the substrate cases 138 and 143, at the locations where the weld lines 192a, 192b, 251a and 251b are generated, the visibility to a specific part inside is lowered due to diffused reflection of light, and the tensile impact strength is extremely lowered. It causes a decrease in mechanical strength such as light.

Therefore, various weld line countermeasures have been taken in the past, such as simulating the flow path of the molten resin in the cavity to predict the occurrence position of the weld line and reinforcing the occurrence location of the weld line. However, it is difficult to solve this weld line problem due to cost and other reasons, and it is one of the important issues common to molded products of home appliances and various other products.

Also in the game machine 1, the one is arranged in a place where the player touches the hand of the player on the front side of the game machines 2 and 3 (for example, the operation button 64 etc.), or the player on the back side of the game machines 2 and 3 Various molded products are used, such as those arranged in a place that cannot be touched (for example, main board case 138, effect board case 134, back cover 22, etc.).

The various board cases 138 and 143 have internal boards 137 and 142 as measures to prevent fraudulent activity against the respective boards 137 and 142 and to facilitate the detection of such fraudulent activity. Although it is configured so that the condition of a specific part of the substrate can be easily confirmed, the traces of the resin pouring portion 192,252 and the weld lines 192a, 192b, 251a, 251b cause a decrease in the visibility inside the substrate cases 138 and 143. Further, the weld lines 192a, 192b, 251a and 251b have a problem of causing a decrease in the mechanical strength of the substrate cases 138 and 143.

Even if the board is used for the same game machine 1, the main board 137 has a very large influence on the result of the whole game, and therefore, it is easy to be targeted as a fraudulent target such as the integrated circuit device 174 being illegally replaced. The main board case 138 that houses the main board 137 is required to have much higher visibility and mechanical strength than the sub board case that houses other sub boards.

Further, even if the position where the weld line is generated can be specified to some extent by simulating the flow path in the cavity of the molten resin, the separately molded products such as the substrate cases 138 and 143 and the back cover 22 overlap. Even if the weld lines 192a, 192b, 251a, 251b of one of the molded products deviate from a specific part of the substrate, the weld lines 192a, 192b, 251a, 251b of the other molded product are arranged. If it overlaps with the specific part, it cannot be said that the visibility of the specific part is secured as a result.

The molded product has an extruded portion mark in addition to the resin pouring portion traces 192 and 252 as the resin molding trace at the time of molding, and the extruded portion trace also contributes to the deterioration of visibility. That is, from the viewpoint of ensuring visibility for a specific part, when the molded product is extruded from the movable mold by the extruded portion, the extruded portion traces 281a and 281b formed corresponding to the extruded portion are also the resin pouring portion traces 192. It is the same as 252 etc.

Therefore, when manufacturing various resin parts used for the game machine 1, molding is performed while considering the optimum requirements for each resin part. For example, in the comparison between the operation button 64, which is the first resin member (cover body) that the player can contact, and the back cover 22, which is the second resin component that the player cannot contact, when the operation button 64 is molded. The number of resin pouring portion traces 90 is N1 (N1 ≧ 1), and the number of resin pouring portion traces 280 at the time of molding the back cover 22 is N1 + n1 (n1 ≧ 1). Incidentally, the number of the resin pouring portion traces 90 of the operation button 64 is one, and the number of the resin pouring portion traces 280 of the back cover 22 is about 5 to 10, for example, 7.

In the case of the operation button 64, it is possible to prevent the occurrence of weld lines by pouring molten resin from one resin pouring portion corresponding to one resin pouring portion trace 90 and molding the resin, and also to pour the resin. Since the number of traces 90 is reduced, it takes time to pour the molten resin, the molding efficiency is lowered, and the manufacturing cost is increased, but there is an advantage that the aesthetic appearance and strength of the operation button 64 after molding are improved.

On the other hand, in the case of the back cover 22, the number of the resin pouring portion traces 280 is 7, which is larger than that of the operation button 64, and at the time of molding, the molten resin is formed from the 7 resin pouring portions corresponding to the resin pouring portion traces 280. Since the molten resin is poured into the cavity, the molding efficiency is improved and the manufacturing cost can be reduced.

Further, there are many traces of the resin pouring portion 280, and the appearance and strength of the back cover 22 after molding are deteriorated due to the generation of the weld line 283, etc., but the back cover 22 is the main board case 138 on the back side of the game machine main bodies 2 and 3. Since it protects from the back side of the plastic and does not come into contact with the player, there is no particular problem of a slight decrease in aesthetics and strength.

Therefore, consider where the resin member is arranged with respect to the game machine main bodies 2 and 3, such as the operation button 64 that the player can contact and the back cover 22 that the player cannot contact. It is necessary to determine the number of resin pouring parts and balance the aesthetics, strength and molding efficiency.

The operation button 64 includes a body portion 68 provided with a flow-inhibiting portion of the molten resin and an operation portion 70 continuously formed on the upper end side of the body portion 68, and the flow-inhibiting portion of the body portion 68. The resin pouring portion trace 90 is arranged on the back side. Two flow-inhibiting portions are arranged on the left and right sides facing each other in the radial direction of the body portion 68, and are composed of a pair of notch portions 68a recessed from the edge of the body portion 68 toward the operation portion 70 side. There is.

The board cases used in the game machine 1 include, for example, a main board case (first board case) 138 for accommodating a main board 137 for game operation control, and an effect board for effect operation control different from the main board 137. There is an effect board case (second board case) 134 for accommodating 133. Taking the main substrate case 138 and the effect substrate case 134 as an example, the number of the resin pouring portion traces 192 and 207 will be considered.

The first case body 180 of the main board case 138 has a resin pouring portion trace 192 as shown in FIG. 35, and the first case body 201 of the effect board case 134 has a resin pouring portion as shown in FIG. There is a mark 207. Assuming that the number of resin pouring portion traces 192 of the main substrate case 138 is N2 (N2 ≧ 1) (for example, 2), the number of resin pouring portion traces 207 of the effect substrate case 134 is N2 + n2 (n2 ≧ 0). ) (For example, 3). Therefore, the number of resin pouring traces 192 and 207 between the main board case 138 and the effect board case 134 is the same, or the number of resin pouring portion traces 207 of the effect board case 134 is the same as the number of resin pouring traces 192 of the main substrate case 138. There are n2 (n2 ≧ 1) more than the number of.

When the main board case 138 and the effect board case 134 are molded by the injection molding method, the traces of the resin pouring portion 192,207 and the weld lines 192a, 192b, 208a, 208b reduce the visibility inside the board cases 134,138. In addition, the weld lines 192a, 192b, 208a, and 208b have a problem of causing a decrease in the mechanical strength of the substrate cases 134 and 138. However, even if the board is used for the same game machine 1, the main board 137 has a very large influence on the result of the whole game. Therefore, the integrated circuit device 174 is illegally replaced as compared with the effect board 133. The main board case 138 that houses the main board 137 is required to have much higher visibility and mechanical strength than the effect board case 134 that houses the effect board 133. It will be.

Therefore, the number of resin pouring portion traces 192 during molding of the main substrate case 138 is less than the number N2 + n2 (n2 ≧ 0) of the number of resin pouring portion traces 207 during molding of the effect substrate case 134 N2 (N2 ≧ 1). By using two, for example, two, it is possible to prevent a decrease in visibility and mechanical strength on the main board case 138 side. Further, by setting the number of the resin pouring portion traces 207 at the time of molding the effect substrate case 134 to N2 + n2 (n2 ≧ 0), the visibility and mechanical strength of the effect substrate case 134 and the liquid crystal substrate case 136 side are slightly lowered. , The molten resin can be easily poured into the cavity, the molding efficiency can be improved, and the manufacturing cost can be reduced.

In addition to the resin pouring portion trace 192 of the main substrate case 138 and the resin pouring portion trace 207 of the effect substrate case 134, the resin pouring portion trace 192 of the main substrate case 138 and the resin pouring portion trace 217 of the liquid crystal substrate case 136. The relationship with is also feasible.

When looking at the relative positions of the back surfaces of the main board case 138, the effect board case 134, and the liquid crystal board case 136 in the front-rear direction, the back surfaces of the effect board case 134 and the liquid crystal board case 136 are substantially at the same position, and the main board case 138 The back surface of the surface protrudes rearward from the effect board case 134 and the like. That is, the back surface of the rear wall portion 180a of the main substrate case 138 projects to the back side of the back surface of the rear wall portion 201a of the effect substrate case 134 and the liquid crystal substrate case 136.

Therefore, as long as the back surface 144 of the back cover 22 corresponding to each board case 134, 136, 138 is substantially flat, the distance between the back surface of the main board case 138 and the back surface 144 of the back cover 22 is the effect board case 134. , It is smaller than the distance between the back surface of the liquid crystal substrate case 136 and the back surface portion 144 of the back cover 22.

In this way, even when the respective substrate cases 134, 136, and 138 are viewed through the back surface 144 of the back cover 22, the visibility of the inside of the main substrate case 138 can be improved by the effect substrate case 134 and the liquid crystal substrate. It is improved as compared with the visibility to the inside of the case 136. The amount of protrusion of the main board case 138, the effect board case 134, and the liquid crystal board case 136 to the rear may be substantially the same.

In the resin back cover 22 that protects the main board case 138, the effect board case 134, and the liquid crystal board case 136, as shown in FIG. 40, a region overlapping the main board case 138 in the lower portion 22D of the back cover 22 is defined. When one region is defined and the region overlapping the effect substrate case 134 and the liquid crystal substrate case 136 in the upper portion 22U of the back cover 22 is defined as the second region, the number of resin pouring portion traces 280 in the first region is N3 (N3 ≧). 1) It is desirable that the number is (for example, 2) and the number of resin pouring portion traces 280 in the second region is N3 + n3 (n3 ≧ 1) (for example, 5). It is desirable that the first region and the second region of the back cover 22 have substantially the same area and volume.

By doing so, in the first region overlapping the lower portion from the main board case 138, the visibility is improved through the back cover 22, and the second region overlapping the effect board case 134 and the liquid crystal board case 136. Even when a large number of heat dissipation holes 264 are arranged in the cavity, the flow of the molten resin in the cavity is not extremely deteriorated due to the molded portion of the heat dissipation holes 264, and the molding efficiency of the back cover 22 does not decrease.

When molding the back cover 22, a plurality of first extruded portions are arranged corresponding to the first extruded portion trace 281a of the back surface portion 144 of the back cover 22, and the second extruded portion of the peripheral portion 145 of the back cover 22. A movable mold in which a plurality of second extrusion portions are arranged corresponding to the trace 281b is used. When the back cover 22 after molding is extruded, the first extruded portion and the second extruded portion on the movable mold side are brought into contact with the back surface portion 144 and the peripheral edge portion 145 of the back cover 22, respectively. The resin part is extruded by simultaneously moving the extruded portion in the extruding direction with the same stroke. Therefore, on the back cover 22 after molding, the first extruded portion trace 281a and the second extruded portion trace 281b remain at a plurality of locations corresponding to each extruded portion.

In this case, as shown in FIG. 40, the first extruded portion trace 281a of the back surface portion 144, which makes it easy to secure the contact area of the first extruded portion, has a large circular shape to secure the contact area of the second extruded portion. The second extruded portion trace 281b of the peripheral portion 145, which is easy to facilitate, has a semicircular shape with a small area, and since the shapes and sizes of the first extruded portion trace 281a and the second extruded portion trace 281b are different, each part of the back cover 22 The back cover 22 can be extruded by an extruded portion having a suitable shape and size.

Further, when the surface area of the back cover 22 is divided into a heat dissipation area 264A in which a plurality of heat dissipation holes 264 are arranged and a non-heat dissipation area 264B other than the heat dissipation area 264A, the heat dissipation area 264A and the non-heat dissipation area 264B Since the degree of adhesion of the back cover 22 to the movable mold is significantly different, the number of the extruded portion traces 281a and 281b of the non-radiating region 264B having a small degree of adhesion is increased according to the difference in the degree of adhesion of the back cover 22 to the movable mold. It is assumed that N5 (N5 ≧ 1) is used, and the number of extruded portion traces 281a and 281b in the heat radiation region 264A having a high degree of adhesion is N5 + n5 (n5 ≧ 1).

For example, in the heat radiating region 264A of the back cover 22, N5 + n5 (n5 ≧ 1) extruded portion traces 281a and 281b are arranged between the heat radiating holes 264 of the back surface portion 144 so as to be substantially evenly distributed. Although a large extrusion resistance is generated by the molded portion of the back cover 22, the heat dissipation region 264A side of the back cover 22 can be extruded against the extrusion resistance.

On the other hand, the number of extruded portions 281a and 281b in the non-heat dissipation region 264B is smaller than the number of N5 (N5 ≧ 1) and the number of extruded portions 281a and 281b on the heat dissipation region 264A side, but the non-heat dissipation region 264B Since the back surface portion 144 has a certain degree of opening, most of which is flat and has a small extrusion resistance, the visibility to the main substrate case 138 is also improved.

The back cover 22 includes a back surface portion 144 that protects the back members of the effect substrate case 134, the liquid crystal substrate case 136, and the like from the back side, and a peripheral edge portion 145 that bends from the outer circumference of the back surface portion 144 to the front side to protect the back member from the outside. It has. When molding such a back cover 22, the molten resin is poured into the cavity from the resin pouring portion and molded in the same manner as other back parts and the like.

The back cover 22 is attached to the left and right mounting portions 20a and 20b on the game machine main body 2 and 3 side, but the front and rear positions of the mounting portions 20a and 20b are different on the left and right due to the relative relationship with the back member and other peripheral members. For such reasons, the back cover 22 itself often has a left-right asymmetric structure. Therefore, when arranging the resin pouring portion in the molding die for the back cover 22, the left and right volume ratios of the left and right bent portions 145a and 145b of the peripheral edge portion 145 are taken into consideration with respect to the entire cavity. The resin pouring portion is arranged so that the circulation of the molten resin becomes substantially uniform.

That is, when looking at the surface region of the back cover 22, as shown in FIG. 40, a first region having a large volume (with reference to a substantially central portion in the left-right direction of the back surface portion 144 of the back cover 22, for example, the center line CL1 ( When the anti-hinge side portion 22R) and the second region (hinge side portion 22L) having a smaller volume than the first region are divided, the number of resin pouring portion traces 280 at the time of molding in the second region is N6 (N6). ≧ 1), and the number of resin pouring portion traces 280 at the time of molding in the first region is N6 + n6 (n6 ≧ 1).

By allocating the number of resin pouring portion traces 280 in consideration of the volume ratio between the first region and the second region in this way, the circulation of the molten resin with respect to the entire cavity becomes substantially uniform, so that the back cover 22 is molded. It is possible to improve the molding efficiency at the time of molding and prevent an extreme decrease in the partial strength of the back cover 22.

The resin pouring portion trace 280 may be arranged on both the back surface portion 144 and the bent portions 145a and 145b of the back cover 22, but it is desirable to arrange the resin pouring portion trace 280 on the back surface portion 144. In the case of the back cover 22 provided with the bent portions 145a and 145b on both the left and right sides of the back portion 144, the bent portion 145a in the first region generally has a larger protruding length than the bent portion 145b in the second region. However, the same applies when the volume is increased or decreased due to factors other than the length of the protrusion. The back cover 22 is attached to the game machine main body 2 and 3 so that one of the bent portions 145a and 145b can be opened and closed by the third hinge means 21, and the other of the bent portions 145a and 145b is attached by the latch means 24 with the back cover 22 closed. Stop at the game machine main body 2 and 3.

In the gaming machine 1 provided with the two members) 138 and provided with through holes such as heat dissipation holes 183 in the region corresponding to the substrate 137 of the substrate case 138, from the viewpoint of ensuring the visibility of a specific portion of the substrate 137, the present invention is used. The specific portion needs to be arranged at a position that does not overlap with the through hole, the weld lines 192a and 192b, the resin pouring portion trace 192, and the extruded portion trace.

Further, in the substrate case 138 for accommodating the substrate 137 on which the electronic component 174 is mounted and the back cover (second member) 22 for protecting the substrate case 138, a plurality of heat dissipation holes (through holes) 183 are provided in the substrate case 138. The same applies when there is.

If the substrate case 138 and the back cover 22 have small through holes, weld lines 192a, 192b, resin pouring portion traces 192, extruded portion traces, etc., light is diffusely reflected at those portions, so that visibility to a specific portion is reduced. Further, if there is a through hole such as a heat radiating hole 183, a weld line 192a is generated on the downstream side of the heat radiating hole 183 when the substrate case 138 and the back cover 22 are molded, so that the weld line 192a makes it difficult to see a specific part and visibility. Decreases. Therefore, in order to ensure the visibility of the specific portion on the substrate 137 side, the specific portion overlaps with the substrate case 138, the through hole of the back cover 22, the weld lines 192a and 192b, the resin pouring portion trace 192, and the extruded portion trace. It is desirable to place it in a position where it does not become.

When the back member including the board case 138 for accommodating the board 137 and the resin back cover 22 for visually protecting the back member side are provided, the back cover 22 is provided from the viewpoint of ensuring the visibility of a specific portion. It is necessary to arrange the trace of the resin molding part provided at the time of molding at a position that does not overlap with the specific part. For example, in the relationship between the first substrate case 138 that houses the main substrate 137 for controlling the game operation and the back cover 22 that overlaps with the first substrate case 138, the resin molded portion trace of the back cover 22 is the first. It is desirable to arrange it at a position that does not overlap with the board case 138. The traces of the resin molding portion at the time of molding include the trace of the resin pouring portion 192 and the trace of the extruded portion.

When a back member including a first board case 138 for accommodating the main board 137 and a resin back cover 22 for visually covering the back member are provided, and the board management information display unit 178 is provided on the main board 137. In order to ensure the visibility of the board management information display unit 178, it is necessary to arrange the trace of the resin molding portion of the back cover 22 at the time of molding at a position that does not overlap with the substrate management information display unit 178.

Even when the back cover 22 overlaps with the first substrate case 138, the trace of the resin molded portion of the back cover 22 is arranged at a position where it does not overlap with the substrate management information display unit 178. The back cover 22 may be provided with an opening for viewing the board management information display unit 178.

45 to 47 illustrate a second embodiment of the present invention. The third hinge means 21 is provided integrally with the hinge shaft 147 provided integrally with the bent portion side of the back cover 22 and the side wall portion 18 of the back protection portion 14 on the front frame 3 side, and the hinge shaft 147 is placed on the upper side. It is equipped with a hinge bearing 148 that can be freely inserted and removed.

The outer peripheral surface of the hinge shaft 147 has a substantially circular shape as a whole, and the hinge shaft 147 has a circular shape having a diameter substantially the same as that of the insertion head 166 on the intermediate side between the lower end insertion head 166 and the upper end support base 165. The reinforcing portion 286 is provided, and a recess 167 is provided between the insertion head 166 and the reinforcing portion 286, and between the reinforcing portion 286 and the support base portion 165 in a substantially U-shaped cross section. Similar to the first embodiment, the recess 167 is recessed in the radial direction from the front surface side of the hinge shaft 147, and is formed long in the vertical axial direction toward the reinforcing portions 286 on both the upper and lower sides.

The hinge bearing 148 is provided on both the upper and lower sides of the outer peripheral holding portion 287 having a substantially U-shape in a plan view held on the reinforcing portion 286 side of the hinge shaft 147, and is arranged on the front side of the hinge shaft 147. An arc-shaped front holding portion 288 is provided, and the outer peripheral holding portion 287 and the front holding portion 288 cooperate to hold the hinge shaft 147 rotatably. If the outer peripheral holding portion 287 has a tubular shape sufficient for holding the hinge shaft 147, the front holding portion 288 is unnecessary. The step portion 289 of the hinge bearing 148 receives the support base portion 165 on the hinge shaft 147 side. Other configurations are the same as in the first embodiment.

Even when the recess 167 is provided in the hinge shaft 147 in this way to eliminate the molding distortion, in addition to the insertion head 166 on the lower end side, one or more reinforcing portions 286 are provided in the vertical direction on the intermediate side. Therefore, the outer circumference of the hinge shaft 147 can be formed in a substantially circular shape. Therefore, even in the hinge shaft 147 that can be identified with a substantially perfect circle or a substantially perfect circle, it is possible to provide the recess 167 to absorb the molding strain.

48 to 50 illustrate a third embodiment of the present invention. The third hinge means 21 is provided integrally with the hinge shaft 147 provided integrally with the bent portion 145a side of the back cover 22 and the side wall portion 18a of the back protection portion 14 on the front frame 3 side, and the hinge shaft 147 is placed on the upper side. A hinge bearing 148 that can be freely inserted and removed is provided, and a regulating means 149 for the back cover 22 is provided between the hinge shaft 147 and the hinge bearing 148.

The hinge shaft 147 projects downward from the support base 165, and the portion excluding the insertion head 166 on the lower end side and the reinforcing portion 286 between the insertion head 166 and the support base 165 has a cross-sectional cross section. It is formed, and a vertical recess 167 is provided between the insertion head 166 and the reinforcing portion 286, and between the reinforcing portion 286 and the support base portion 165.

Therefore, in this hinge shaft 147, the entire outer peripheral surface including the insertion head 166 and the reinforcing portion 286 has a substantially circular shape, and four recesses 167 in the circumferential direction are provided on both the upper and lower sides of the reinforcing portion 286. It is formed in the vertical direction.

The hinge bearing 148 has a pair of left and right holding members 290 protruding rearward from the support base 169 of the side wall portion 18a of the back protection portion 14, and the hinge shaft 147 can be rotated and inserted / detached between the left and right holding members 290. It is designed to be held in.

The regulating means 149 includes a regulating portion 291 formed on the lower surface of one holding member 290 on the hinge bearing 148 side, a regulating protrusion 292 projecting radially from the hinge shaft 147 on the lower side of the regulating portion 291, and left and right. A notch-shaped release portion 293 formed so that the regulation protrusion 292 can pass up and down is provided between the rear ends of the holding member 290.

Therefore, this regulating means 149 restricts the upward movement of the regulating protrusion 292 by the regulating portion 291 on the lower side of the hinge bearing 148 until the back cover 22 is opened from the closed state to the attachment / detachment position 22B, and the back cover When the 22 is opened to the attachment / detachment position 22B by a predetermined angle, the regulation of the regulation protrusion 292 by the regulation portion 291 is released, and the regulation protrusion 292 corresponds to the release portion 293 between the left and right holding members 290, and the release portion 293 thereof is released. Is designed to pass upward.

When the hinge shaft 147 is provided with the recesses 167 in this way to absorb the molding strain, it is also possible to form the hinge shafts 147 in a cross-shaped cross section and provide a plurality of recesses 167 in the circumferential direction. Further, it is also possible to provide a reinforcing portion 286 in the middle of the hinge shaft 147 and to make the outer peripheral shape other than the reinforcing portion 286 a substantially perfect circle or a shape that can be equated with a substantially perfect circle.

Further, the regulating means 149 can be incorporated into the third hinge means 21 by providing the regulating protrusion 292 on the hinge shaft 147 and providing the regulating portion 291 and the releasing portion 293 on the hinge bearing 148. In this regulating means 149, the regulating portion 291 of the hinge bearing 148 regulates the rise of the regulating protrusion 292 of the hinge shaft 147 until the back cover 22 is opened by a predetermined angle, and the hinge shaft 147 is moved upward from the hinge bearing 148. The back cover 22 cannot be removed by pulling it out. However, if the back cover 22 is opened at a predetermined angle, the regulation protrusion 292 of the hinge shaft 147 corresponds to the release portion 293 of the hinge bearing 148, and the regulation protrusion 292 can pass through the release portion 293. 22 can be removed. When the back cover 22 is attached, it may be performed in the reverse order.

51 to 56 illustrate a fourth embodiment of the present invention. As shown in FIGS. 51 to 54, the third hinge means 21 includes a hinge shaft 147 provided integrally with the bent portion 145a side of the back cover 22, and a side wall portion 18a of the back protection portion 14 on the front frame 3 side. It is provided with a hinge bearing 148 that is integrally provided and receives the hinge shaft 147 on the upper side so as to be removable.

Further, in each of the plurality of third hinge means 21 in the vertical direction, the first regulation that regulates the removal of the back cover 22 within the first regulation range 294A close to the closed position 22A between the hinge shaft 147 and the hinge bearing 148. The means 294 and the second regulating means 295 that regulate the removal of the back cover 22 in the second regulating range 295A far from the closed position 22A are provided. It is sufficient that the first regulating means 294 and the second regulating means 295 are in at least one third hinge means 21 among the plurality of third hinge means 21 in the vertical direction.

Similar to the second embodiment, the hinge shaft 147 includes an insertion head 166 on the lower end side and a recess 167 formed in the vertical direction between the insertion head 166 and the support base 165. The hinge bearing 148 includes a first receiving portion 296a that receives the hinge shaft 147 from the front side, and a second receiving portion 296b that is provided between the first receiving portions 296a and receives the hinge shaft 147 from the rear side.

The first regulating means 294 includes a regulating portion 291 provided on the upper side of the support base portion 165 and a regulating protrusion 292 provided on the hinge bearing 148 side on the upper side of the regulating portion 291, and the back cover 22 is in a closed position. Within the first regulation range 294A from 22A to the first position 22a, the regulation protrusion 292 regulates the rise of the regulation part 291 and the regulation protrusion 292 regulates when the back cover 22 is opened to the first regulation range 294A or more. It is designed to lift the regulation by leaving the section 291. Therefore, when the back cover 22 is opened within the first regulation range 294A, the back cover 22 cannot be removed due to the regulation of the first regulation means 294. Therefore, when the back cover 22 is removed, the back cover 22 is first. It is necessary to open the regulation range of 294A or more.

Even after the regulation is lifted by the first regulating means 294, the major axis of the hinge shaft 147 of the second regulating means 295 is in the second regulating range 295A from the second position 22b to the third position 22c near the first position 22a. A second regulating means for the portion 147A to come into contact with the first receiving portion 296a and the second receiving portion 296b of the hinge bearing 148 to regulate the vertical relative sliding between the hinge shaft 147 and the hinge bearing 148. Due to the restricting action of 295, it is possible to prevent the back cover 22 from being unstablely rotated around the hinge shaft 147 and unexpectedly falling off due to the hinge shaft 147 coming off.

That is, when the back cover 22 is in the second regulation range 295A, the major axis portion 147A of the hinge shaft 147 is the first receiving portion 296a and the second receiving portion 296b of the hinge bearing 148 as shown in FIG. 55. It is approximately the same as the minimum interval 296A or slightly larger than the minimum interval 296A. Therefore, when the back cover 22 is opened to the second regulation range 295A, the sliding portions at both ends of the major axis portion 147A of the hinge shaft 147 are the first receiving portion 296a and the second receiving portion 296b of the hinge bearing 148. Since the hinge shaft 147 and the hinge bearing 148 slide relatively around the hinge shaft 147 while abutting against the sliding portion and resisting the frictional resistance, the hinge shaft 147 and the hinge bearing 148 slide in the vertical direction. Relative sliding will be regulated.

The short diameter portion 147B of the hinge shaft 147 has a diameter smaller than the minimum distance 296A of the hinge bearing 148, and the back cover 22 is opened from the first regulation range 294A to the second regulation range 295A to shorten the hinge shaft 147. At a position where the diameter portion 147B corresponds to the minimum distance 296A of the hinge bearing 148, the hinge shaft 147 is vertically inserted and removed from the hinge bearing 148 to attach and detach the back cover 22.

In the second regulation means 295, the hinge shaft 147 and the hinge bearing 148 are tightened in the second regulation range 295A, and the hinge shaft 147 and the hinge bearing 148 are loosened and playable outside the second regulation range 295A. .. Therefore, the tightness of the third hinge means 21 is different from that of the second regulation range 295A in other cases, and when the back cover 22 is in the second regulation range 295A, even if the back cover 22 is forcibly removed, the third hinge The means 21 cannot be removed.

Therefore, when performing maintenance or the like with the back cover 22 open to the second regulation range 295A of FIG. 56, even if the back cover 22 comes into contact with the tip side of the back cover 22, the second regulation means 295 is used. Since the frictional resistance between the hinge shaft 147 and the hinge bearing 148 is large, it is possible to prevent the hinge shaft 147 from coming off the hinge bearing 148 and the back cover 22 from unexpectedly falling off.

Further, when the back cover 22 is opened from the first regulation range 294A to the second regulation range 295A, the frictional resistance between the hinge shaft 147 and the hinge bearing 148 becomes large by the second regulation means 295, and the frictional resistance is resisted. Since the hinge shaft 147 and the hinge bearing 148 slide relative to each other around the axis center, it is possible to prevent the back cover 22 in the open state from rotating unstablely around the third hinge means 21.

When the back cover is attached, the hinge shaft 147 may be inserted into the hinge bearing 148 at an open position where the back cover 22 is separated from the first regulation range 294A and the second regulation range 295A. In this open position, the minor axis portion 147B of the hinge shaft 147 corresponds to the minimum spacing 296A of the hinge bearing 148, so that the hinge shaft 147 can be easily inserted into the hinge bearing 148.

Further, if the hinge shaft 146 is inserted into the hinge bearing 148 and then the back cover 22 is rotated to the closed position 22A, the sliding portion of the major axis portion 147A of the hinge shaft 147 is moved to the hinge bearing 148 by the second regulating means 295. It rotates while resisting the frictional resistance between the two corresponding to the sliding portion having the minimum distance of 296A. As a result, when the back cover 22 rotates in the second regulation range 295A around the third hinge means 21 to the closed position 22A, the back cover 22 moves up and down due to play between the hinge shaft 147 and the hinge bearing 148. It is possible to prevent rattling in the direction.

Therefore, it can be said that the back cover 22 is rotated from the second regulation range 295A through the first regulation range 294A to the closed position 22A, but the back cover 22 is in the closed position as compared with the case where the second regulation means 295 is not provided. When 22A is reached, the latch means 24 can be located at or near the mounting hole 153. Therefore, even if the back cover 22 has a relatively low rigidity, the latch means 24 can be easily aligned with the mounting hole 153.

It is also possible to omit the first regulating means 294 and provide a second regulating range 295A in which the second regulating means 295 exerts a regulating function up to the closed position 22A or its vicinity. In this case, since the second regulating means 295 functions to the closed position 22A or its vicinity to regulate the rattling of the third hinge means 21, the positioning of the latch means 24 with respect to the mounting hole 153 becomes easier.

The major axis portion 147A of the hinge shaft 147 may be substantially the same as the distance 296A of the hinge bearing 148, or may be slightly larger or smaller than the distance 296A. When the major axis portion 147A of the hinge shaft 147 is slightly larger than the spacing 296A, the hinge shaft 147 and / or the hinge bearing 148 may be configured to be elastically deformable in the tightening direction. The first regulation range 294A and the second regulation range 295A may partially overlap, or there may be a slight gap between the first regulation range 294A and the second regulation range 295A.

For example, since the hinge shaft 147 has a U-shaped cross section due to the recess 167 for the purpose of absorbing molding strain, the U-shaped cross section U is formed by appropriately adjusting the wall thickness of the hinge shaft 147 having a U-shaped cross section. An appropriate elastic force can be provided on the open end side of the character. Further, by appropriately adjusting the wall thickness of the U-shaped second receiving portion 296b of the hinge bearing 148, the hinge bearing 148 can be provided with an appropriate elastic force in the front-rear direction.

57 to 61 illustrate a fifth embodiment of the present invention. As shown in FIGS. 57 to 60, the plurality of third hinge means 21 in the vertical direction include a hinge shaft 147 provided on the back cover 22 side and supported by support bases 165 on both upper and lower ends in a double-sided manner. It is provided with a hinge bearing 148 provided on the back protection portion 14 side of the front frame 3 and which receives the hinge shaft 147 detachably in the radial direction thereof.

As shown in FIG. 61, the hinge shaft 147 is provided with a recess 167 between the upper and lower support bases 165, and has a U-shaped cross section in which the major axis portion 147A and the minor axis portion 147B are formed in a right angle direction. Is. Further, in the intermediate portion of the hinge shaft 147, a reinforcing portion 286 also used as a guide is provided in a direction crossing the recess 167.

The hinge bearing 148 has a pair of left and right bearing protrusions 297 protruding rearward from the back protection portion 14 side of the front frame 3, and a pair of upper and lower connecting portions 298 that connect the upper and lower ends of the bearing protrusion 297 to the left and right. The upper and lower connecting portions 298 are provided with a first receiving portion 298a for holding the hinge shaft 147 from the front side, and the left and right bearing protrusions 297 are provided with a second receiving portion 298b for holding the hinge shaft 147 from the left and right. Between the rear ends of the bearing protrusion 297, an insertion / removal portion 299 capable of inserting / removing the hinge shaft 147 in the front-rear direction is provided.

The distance between the rear ends of the left and right bearing protrusions 297, that is, the left and right width of the insertion / removal portion 299, is slightly smaller than the dimension of the minor diameter portion 147B of the hinge shaft 147, and is rear of the left and right bearing protrusions 297. By elastically deforming one or both of the ends to the outside in the left-right direction, the minor axis portion 147B of the hinge shaft 147 can pass back and forth through the insertion / removal portion 299.

The insertion / removal portion 299 may have the same dimensions as the minor diameter portion 147B of the hinge shaft 147. The vertical width of the bearing protrusion 297 is slightly smaller than the distance between the support bases 165, and the relative vertical movement of the third hinge means 21 is regulated between the bearing protrusion 297 and the support bases 165 above and below the bearing protrusion 297. ing.

In the third hinge means 21 having such a configuration, when the back cover 22 is attached via the third hinge means 21, the short diameter portion 147B of the hinge shaft 147 is inserted and removed from the hinge bearing 148 as shown in FIG. After making it correspond to the portion 299, the hinge shaft 147 side is pressed toward the front frame 3 side in that state. Then, the minor axis portion 147B of the hinge shaft 147 elastically deforms the rear end portions of the left and right bearing protrusions 297 of the hinge bearing 148 outward, so that the distance between the rear end portions of the left and right bearing protrusions 297 widens and the minor axis The portion 147B passes through the insertion / removal portion 299 and enters between the left and right bearing protrusions 297, and the hinge shaft 147 is rotatably held by the left and right bearing protrusions 297.

A recess 167 is formed in the hinge shaft 147 to prevent molding distortion, and the cross-sectional shape of the hinge shaft 147 is substantially U-shaped, but since there is a reinforcing portion 286 in the middle of the recess 167. Even when the minor axis portion 147B of the hinge shaft 147 passes between the rear ends of the left and right bearing protrusions 297, the rear end corresponding to the open end side of the recess 167 may be caught in the recess 167. Instead, the minor axis portion 147B of the hinge shaft 147 can quickly pass between the rear ends of the left and right bearing protrusions 297.

After the minor axis portion 147B of the hinge shaft 147 passes through the insertion / removal portion 299 and enters between the left and right bearing protrusions 297, when the back cover 22 is rotated around the hinge shaft 147, the major axis portion 147A of the hinge shaft 147 Corresponds between the left and right bearing protrusions 297, so that the hinge shaft 147 does not fall off from the hinge bearing 148.

In particular, the hinge shaft 147 has a substantially U-shaped cross section due to the recess 167, but since there is a reinforcing portion 286 in the middle of the recess 167, an external force in the compression direction is applied to the major axis portion 147A side of the hinge shaft 147. Even if this happens, the major axis portion 147A of the hinge shaft 147 corresponding to the reinforcing portion 286 will not be elastically deformed in the compression direction. Therefore, even though the hinge shaft 147 has the recess 167, the hinge shaft 147 does not unexpectedly fall off from the hinge bearing 148.

When removing the back cover 22, the back cover 22 is opened rearward, the short diameter portion 147B of the hinge shaft 147 is aligned with the insertion / detachment portion 299 of the hinge bearing 148, and the back cover 22 is pulled rearward in that state. For example, the left and right bearing protrusions 297 are elastically deformed outward, and the hinge shaft 147 is detached from the hinge bearing 148, so that the back cover 22 can be easily removed.

In this way, it is also possible to support the upper and lower sides of the hinge shaft 147 with the support base portion 165 in a double-sided manner. When the back cover 22 is attached to the game machine main bodies 2 and 3, a plurality of third hinge means 21 are arranged in the vertical direction, and the plurality of third hinge means 21 are provided with the examples of the fifth embodiment. Alternatively, as illustrated in the first embodiment, the third hinge means 21 other than the one may be of a type that is inserted and removed from the upper side.

In addition, when the hinge shaft 147 is provided with the recess 167 to prevent molding distortion while increasing the diameter of the hinge shaft 147, it is generally appropriate to arrange one recess 167 in the circumferential direction. It is also possible to arrange a plurality of them in the circumferential direction. When the hinge shaft 147 is provided with the recess 167, the hinge shaft 147 is generally in a substantially elliptical shape having a major axis portion 147A and a minor axis portion 147B, but may have a substantially elliptical shape. , May be configured in a substantially perfect circle. Further, when the hinge shaft 147 is provided with the major axis portion 147A and the minor axis portion 147B, the outer peripheral shape of the hinge shaft 147 is substantially an oval shape, a substantially elliptical shape, a substantially perfect circle shape, or a rounded triangular shape. It may be rectangular or the like.

The back cover is within the range of the first angle to the second angle even when the regulation is released by the first regulating means 294 and the first regulating means 294 that regulate the removal of the back cover 22 until the first angle is opened at a predetermined angle. A second regulatory means 295 is provided to regulate 22 unexpected dropouts.

The hinge shaft 147 is provided with a recess 167 between the insertion head 166 and the support base 165 as in the first embodiment, and has a cross section in which the major axis portion 147A and the minor axis portion 147B are formed in a right angle direction. It is a U-shaped oval. The hinge bearing 148 includes a pair of upper and lower first receiving portions 296a that receive the hinge shaft 147 from the front side, and a second receiving portion 296b that is provided between the first receiving portions 296a and receives the hinge shaft 147 from the rear side. The first receiving portion 296a and the second receiving portion 296b support the entire circumference of the hinge shaft 147 so as to be rotatable and removable.

The first regulating means 294 includes a regulating portion 291 provided on the upper side of the support base portion 165 and a regulating protrusion 292 provided on the hinge bearing 148 side on the upper side of the regulating portion 291, and the back cover 22 is in a closed state. The regulation protrusion 292 regulates the rise of the regulation portion 291 within the range of opening to the first angle of the predetermined angle, and when the back cover 22 is opened to the first angle or more, the regulation protrusion 292 comes off from the regulation portion 291. The regulation is lifted. Therefore, until the back cover 22 is opened to the first angle or more, the back cover 22 cannot be removed due to the regulation of the first regulating means 294. Therefore, when the back cover 22 is removed, the back cover 22 is first. It is necessary to open more than the angle.

FIG. 62 illustrates a sixth embodiment of the present invention. In this embodiment, the back cover 22 does not overlap with the main board case 138 (first board case), the payout board case 143 and the power supply board case 141 arranged below the main board case 138 (first board case), and is on the upper side of the main board case 138. It is designed to overlap and protect the back members such as the effect board case 134 (second board case) and the liquid crystal board case 136 (second board case) arranged on the left and right.

Even in such a back cover 22, a resin pouring portion trace 280 and an extruded portion trace 281 which are traces of the resin molding portion at the time of molding are formed. However, when the back cover 22 does not overlap the main board case 138 and the payout board case 143, the main board 137 in the main board case 138 and the payout board 142 in the payout board case 143 have specific parts to be visually recognized. However, the main substrate case 138, the resin pouring portion trace 280, and the extruded portion trace 281 of the payout substrate case 143 may not overlap each other with respect to the specific portion.

On the other hand, when the back cover 22 overlaps with the effect substrate case 134 and the liquid crystal substrate case 136, the effect substrate 133 in the effect substrate case 134 and the liquid crystal substrate 135 in the liquid crystal substrate case 136 are required to be visible from the outside. If there is a substrate control number or other specific parts, it is necessary to arrange the resin casting part traces 280 and the extruded part traces 281 at positions that do not overlap with the specific parts.

The back surface portion 144 of the back cover 22 has a heat dissipation region 264A having a plurality of heat dissipation holes 264 on the upper side thereof, and a flat non-perforated non-heat dissipation region 264B on the lower side of the heat dissipation region 264A. In the effect board 133 in the effect board case 134 and the liquid crystal substrate 135 in the liquid crystal board case 136, specific parts such as a substrate control number are arranged in a portion corresponding to the non-heat dissipation region 264B of the back cover 22.

The resin pouring portion trace 280 and the extruded portion trace 281 of the back cover 22 are dispersedly arranged on the back surface portion 144. On the heat radiating region 264A side, a large number of resin pouring portion traces 280 and extruded portion traces 281 are dispersedly arranged so as to be located between the heat radiating holes 264. On the non-heat dissipation region 264B side, a smaller number of resin pouring portion traces 280 and extruded portion traces 281 are arranged than on the heat dissipation region 264A side, and the positions of the resin pouring portion traces 280 and the extruded portion traces 281 are not. It is arranged at a position that does not overlap with a specific part such as the component information display unit 179 on the main board 137 side at least, such as being arranged in the peripheral portion of the heat dissipation area 264B.

The number of resin pouring traces 192 of the main board case 138 is N2 (N2 ≧ 1), for example, one or two, and the number of resin pouring traces 90 at the time of molding the back cover 22 is N2 + n4 (n4 ≧ 1). ), For example, about 4 to 6 pieces. Of course, the resin pouring portion trace 192 of the main substrate case 138 is arranged so as not to overlap with the specific portion of the main substrate 137, such as being arranged in the peripheral portion of the main substrate case 138.

When the number of resin pouring portion traces 192 of the main substrate case 138 is N2 (N2 ≧ 1), the number of resin pouring portion traces 207 and 217 on the effect substrate case 134 and / or the liquid crystal substrate case 136 side is N2 + n2. About (n2 ≧ 0) is desirable.

By doing so, even if there is a specific part on the effect board 133 side in the effect board case 134 and there is a specific part on the liquid crystal substrate 135 side in the liquid crystal board case 136, the specific part via the back cover 22 Visibility can be ensured.

Further, the main board case 138 is removed from the back cover 22, and the main board case 138 is not protected by the back cover 22, but the number of resin pouring portion traces 192 of the main board case 138 is N2 (N2 ≧ 1). Since the number of traces of the resin pouring portion 90 of the back cover 22 is less than N2 + n4 (n4 ≧ 1), the number of weld lines generated is also smaller than that of the back cover 22, and the strength of the main board case 138 is ensured. Can be done.

FIG. 63 illustrates a seventh embodiment of the present invention. As shown in FIG. 63, a first regulating means 294 and a second regulating means 295 are provided between the back cover 22 side and the front frame 3 side of this embodiment.

The first regulating means 294 regulates the removal of the back cover 22 when the back cover 22 is in the vicinity of the closed position 22A between the closed position 22A and the first position 22a.

The hinge shaft 147 of the third hinge means 21 may be removed from the hinge bearing 148.

However, even if the back cover 22 is opened, if the back cover 22 is closer to the closed position 22A than the first position 22a, even if the back cover 22 is lifted, the first regulating means 294 is on the upper side of the back cover 22. Since there is a guide rail 49 and a second regulating means 295 on the third hinge means 21 side, the back cover 22 cannot be lifted until the hinge shaft 147 of the third hinge means 21 is separated from the hinge bearing 148.

While the back cover 22 is closer to the closed position 22A than the first position 22a, the first regulating means 294 and the second regulating means 295 cooperate to regulate the removal of the back cover 22, so that only one of them is used. It is possible to reduce the individual burdens of the first regulating means 294 and the second regulating means 295 as compared with the case of regulating with.

If the back cover 22 is opened beyond the first position 22a, the back cover 22 is removed from the guide rail 49 of the first regulating means 294, so that the regulation of the back cover 22 by the first regulating means 294 is released, but the back cover 22 is released. The second regulating means 295 restricts the removal of the back cover 22 until the cover 22 exceeds the second position 22b. If the back cover 22 is opened until it exceeds the second position 22b, the regulation of the back cover 22 by the second regulating means 295 is released, so that the back cover 22 can be lifted upward, and the hinge shaft 147 of the third hinge means 21 can be lifted. Can be removed from the hinge bearing 148 to remove the back cover 22.

When the first hinge means 6 and the third hinge means 21 are arranged on the same side in the left-right direction in this way, the front frame 3 is placed on the island equipment 150 side of the game hall with the game machine 1 mounted on the same side. 1 When the hinge means is opened around 6 and then the back cover 22 is opened around the 3rd hinge means 21, the back cover 22 is opened so as to approach the outer frame 2 as shown in FIG. 65. Therefore, the back side of the game machine 1 is largely opened to the passage side between the island facilities 150, and work such as maintenance and inspection can be easily performed.

The back protection portion 14 on the back side of the front frame 3 is provided with mounting portions 20a and 20b having substantially the same height at the rear ends of the side wall portions 18a and 18b, and the mounting portions 20b on the first hinge means 6 side thereof. The extension mounting portion 300 is provided with a payout means 23, a ball supply passage 51, and the like, and the back cover 22 is pivotally attached to the extension mounting portion 300 via a pair of upper and lower third hinge means 21 so as to be openable and closable. The back cover 22 is fixed to the mounting portion 20a on the opposite side via the latch means 24.

As shown in FIGS. 66 and 67, the back cover 22 has a back surface portion 144 that protects back components such as the effect board case 134, the liquid crystal substrate case 136, and the main board case 138 from the back side, and the back surface portion 144 from the outer periphery thereof. It has a peripheral portion 145 that is formed in a bent shape on the front side and protects back parts such as the effect substrate case 134 and the main substrate case 138 from the outer peripheral side.

The side is a flat, non-perforated non-heat dissipation region 264B. On the heat radiating region 264A side, a plurality of resin pouring portion traces 280 and extruded portion traces 281 are dispersedly arranged so as to be located between the heat radiating holes 264. Further, on the non-heat dissipation region 264B side, a smaller number of resin pouring portion traces 280 and extruded portion traces 281 are arranged than on the heat dissipation region 264A side, and the positions of the resin pouring portion traces 280 and the extruded portion traces 281 are non-heat dissipation. It is arranged at a position that does not overlap with a specific part such as the opening history notation means 184 of the main substrate 137, such as being arranged in the peripheral portion of the area 264B.

The resin pouring portion trace 280 of the back cover 22 has about 3 to 5 heat dissipation areas 264A including the vicinity side of the non-heat dissipation area 264B, and the number of non-heat dissipation areas 264B including the vicinity side of the heat dissipation area 264A. It is about 1 to 2 pieces. Then, when the distribution of the resin pouring portion traces between the first region 22D on the third hinge means 21 side and the second region 22U on the opposite side is observed with the back cover 22 as the center line at the center of the left and right sides, the molding die In order to make the circulation of the molten resin in the cavity for the back cover 22 substantially uniform, the number of the resin pouring portion traces 280 on the second region 22U side where the bending length of the bending portion 145a is long and the volume is large is bent. The bending length of the portion 145b is short and the volume is smaller than the number of the resin pouring portion traces 280 on the second region 22U side.

Further, when the component information display unit 179 of the integrated circuit device 174 of the main board 137 is designated as a specific portion, the weld line 283 generated between the upper and lower resin pouring portion traces 280 on the non-heat dissipation region 264B side of the back cover 22 is formed. It is placed at a position that does not overlap with a specific part. Of course, the weld line 192b generated between the adjacent resin pouring portion traces 192 of the main substrate case 138 is also arranged at a position that does not overlap with the specific portion.

Extruded portion traces 281b and 281c are also arranged at the front end of the peripheral portion 145 of the back cover 22, but the extruded portion trace 281b on the bent portion 145b side having a short bending length is semicircular and has a long bending length. The extruded portion trace 281c on the bent portion 145a side has a rectangular shape along the bent portion 145a.

Although each embodiment of the present invention has been described in detail above, the present invention is not limited to each embodiment, and various modifications can be made without departing from the spirit of the present invention. Although the pachinko machine is illustrated in the embodiment, it can be similarly implemented in a game machine 1 such as a ball game machine and an arrange ball machine in addition to the pachinko machine.

A plurality of back members arranged on the back surface side of the game machine main bodies 2 and 3 and a back cover 22 for protecting at least one of the back members of the plurality of back members are provided, and the back cover 22 is provided within a predetermined angle. In the game machine 1 that can be opened and closed and is further detachable, the back cover 22 is provided with regulatory means 149,294,295 for restricting the removal of the back cover 22 when the opening angle of the back cover 22 is less than a predetermined angle. It may be removable after the regulation is lifted by means 149.

In that case, the hinge means 21 that supports the back cover 22 so as to be openable / detachable may be provided, and the regulating means 149, 294, 295 may be arranged in the vicinity of the hinge means 21 and / or provided in the hinge means 21. Further, on the upper side of the back cover 22, a ball tank 48 for storing game balls and a guide rail 49 for guiding the game balls from the ball tank 48 to the payout means 23 are provided, and the regulating means 149 includes the ball tank 48 and the ball tank 48. / Or may be configured by a guide rail 49.

A plurality of back members arranged on the back surface side of the game machine main bodies 2 and 3 and a back cover 22 for protecting at least one of the back members of the plurality of back members are provided, and the back cover 22 is a hinge shaft made of resin. In the game machine 1 having 147 and capable of opening and closing the back cover 22 by inserting the hinge shaft 147 into the hinge bearings 148 on the game machine main bodies 2 and 3, the hinge shaft 147 is in the radial direction of the hinge shaft 147. It may be provided with a recess 167 that is recessed into the recess.

In that case, the recess 167 may be elongated in the axial direction of the hinge shaft 147. The hinge shaft 147 may have a substantially U-shaped cross section in the direction crossing the recess 167. Further, the hinge shaft 147 has an oval shape, an elliptical shape, or the like having a major axis portion 147A and a minor axis portion 147B, and when the hinge shaft 147 is inserted into the hinge bearing 148 and rotated from the first angle to the second angle, At the first angle, at least one of the major axis portions 147A may not abut on the inner wall of the hinge bearing 148, and at the second angle, the major axis portion 147A may abut on the inner wall of the hinge bearing 148.

The hinge shaft 147 has a side-holding shape integrated with the back cover 22 on one end side in the axial direction of the hinge shaft 147, and an insertion head (insertion end portion) for closing the recess 167 is on the other end side of the hinge shaft 147. ) 166 may be provided. The hinge shaft 147 may have a double-sided shape integrated with the back cover 22 on both ends in the axial direction of the hinge shaft 147.

In the game machine 1 provided with the first resin member that the player can contact and the second resin member that the player cannot contact, the number of traces of the resin pouring portion at the time of molding the first resin member is N1 (N1 ≧). 1) The number may be N1 + n1 (n1 ≧ 1), and the number of traces of the resin poured portion at the time of molding the second resin member may be N1 + n1 (n1 ≧ 1).

In that case, the first resin member is a cover body in the operating means that can be operated by the player, and the second resin member is a back cover 22 that protects the back members arranged on the back surface side of the game machine main bodies 2 and 3. It may be. The back cover 22 includes a body portion 68 provided with a flow blocking portion of the molten resin and an operation top portion continuously formed on the upper end side of the body portion 68, and is provided on the side of the body portion 68 without the flow blocking portion. The trace of the resin pouring portion may be arranged. Further, the flow inhibiting portion may be a pair of notched portions 68a which are arranged so as to face each other in the radial direction of the body portion 68 and which are recessed from the end edge of the body portion 68 toward the operation top side.

As a specific example of the first resin member that the player can contact, the cover body of the operating means has been mentioned, but the present invention is not limited to this. For example, the lower cover 62 that covers the outer peripheral sides of the upper plate 52 and the lower plate 61, the resin portion in the movable effect means 97, and the like may correspond to the first resin member.

However, it is not appropriate from the viewpoint of cost effectiveness to use all the resin parts that the player can contact as the first resin member. Therefore, among the resin portions that the game machine can contact, the number of resin pouring portions may be N1 or N1 + n1 or more. For example, (i) a resin part such as a handle or an operating means that may be violently touched (pulled or struck), and (ii) an upper plate or a lower plate may be touched in the process of playing. The resin part (which is supposed to come into contact), (iii) the resin part which is not supposed to come into contact with the movable effect means provided on the game machine frame, but which hinders the game if it is intentionally destroyed, (iv). Considering "contact possibility" and "influence in case of destruction" such as other resin parts, N1 is not the case if it is judged that the possibility or influence is large. For those judged to be, N1 + n1 or more may be used.

To exemplify the combination, only the above (i) is N1, the above (i) and (ii) are N1, and the above (i), (ii) and (iii) are N1. It is conceivable that i) and (iii) are set to N1, and only the above (iii) is set to N1.

It is also possible to consider the possibility of damage from another perspective. That is, the game machine may be damaged not only due to the contact by the player but also due to the operation of the clerk. Of course, it is not intentionally destroyed or damaged, but it may be accidentally damaged at various timings such as assembly, installation, maintenance during business hours or outside business hours.

Therefore, based on the magnitude of the possibility of damage due to the negligence of the clerk, those with a high possibility may be regarded as the first resin member. For example, when considering the size of damage on the premise of "falling over of the game machine" at the time of installation, the damage to the back side of the game machine is invisible to the player, so there is no effect on the function and it is just an aesthetic appearance. There is no particular problem as long as it is damaged to the extent that it is damaged (scratches, etc.).

However, if the front side of the game machine is damaged, it does not give a good impression to the player even if the function is not affected at all. Therefore, when the game machine falls to the front side, higher strength is required for the part that first touches the ground (for example, the upper plate unit, the handle, etc.) due to the unevenness. The resin portion at such a portion may be used as the first resin member.

Not limited to this, if "contact when the door is opened" during maintenance is assumed, the part that may first contact the adjacent table (for example, the left end or the right end, or the amount of protrusion) A large portion or the like) may correspond to the first resin member.

On the back side of the game machine main bodies 2 and 3, a resin first board case 138 that houses the main board 137 that controls the game operation and a resin second board case 134 that houses a board different from the main board 137. The number of the resin pouring portion traces 192 at the time of molding the first substrate case 138 is set to N2 (N2 ≧ 1), and the resin pouring portion traces 207 at the time of molding the second substrate case 134 The number may be N2 + n2 (n2 ≧ 0).

In that case, it is desirable that the rear wall portion (back surface portion) 180a of the first substrate case 138 protrudes to the back side of the rear wall portion (back surface portion) 201a of the second substrate case 134. A resin back cover 22 that protects at least the first substrate case 138 and the second substrate case 134 is provided, and the region of the back cover 22 that overlaps with the first substrate case 138 is set as the first region, and the second substrate case of the back cover 22 is provided. When the region overlapping with 134 is the second region, the number of resin pouring portion traces 280 in the first region is N3 (N3 ≧ 1), and the number of resin pouring portion traces 280 in the second region is N3 + n3 (n3 ≧ 1). ) May be individual.

A resin back cover 22 that protects the second substrate case 134 and does not protect the first substrate case 138 is provided, and the number of resin pouring portion traces 192 of the first substrate case 138 is N4 (N4 ≧ 1). The number of resin pouring portion traces 280 at the time of molding the cover 22 may be N4 + n4 (n4 ≧ 1).

The second extruded portion traces 281a and 281b at the time of molding, which are arranged at the two positions, may be configured to have different sizes from each other.

In that case, the first resin component is a resin back cover 22 that protects the back member, and the surface area of the back cover 22 is other than the heat dissipation area 264A in which a plurality of heat dissipation holes 264 are arranged and the heat dissipation area 264A. When divided into the non-heat dissipation region 264B, the number of the extruded portion traces 281a and 281b in the non-heat dissipation region 264B is N5 (N5 ≧ 1), and the number of the extruded portion traces 281a and 281b in the heat dissipation region 264A is N5 + n5 (n5 ≧ 1). 1) It may be an individual piece. Further, the back cover 22 includes a back surface portion 144 that protects the back member from the back side, and bent portions 145a and 145b that bend from the outer circumference of the back surface portion 144 to the front side, and the extruded portion traces 281a and 281b are on the back surface portion 144 side. The size may be different on the bent portions 145a and 145b sides.

In the game machine 1 provided with the resin back cover 22 that protects the back member, the surface region of the back cover 22 is set from the first region having a large volume and the first region with reference to the substantially central portion in the left-right direction. When divided into a second region having a small volume, the number of resin pouring portion traces 280 during molding in the second region is N6 (N6 ≧ 1), and the number of resin pouring portion traces 280 during molding in the first region is set to N6 (N6 ≧ 1). The number may be N6 + n6 (n6 ≧ 1).

In that case, the back cover 22 includes a back surface portion 144 that covers the back member from the back side, and bent portions 145a and 145b that bend from the outer circumference of the back surface portion 144 to the front side, and the resin pouring portion trace 280 is arranged on the back surface portion 144.

You may do so.

When molding the resin parts, it is necessary to use an appropriate resin material according to the conditions required for each part. Resin parts with excellent heat resistance are used for resin parts that require heat resistance, resin materials with excellent transparency are used for resin parts that require transparency, and resin parts that require impact resistance are resistant to impact. Resin materials with excellent impact resistance are used respectively. On the contrary, for resin parts having relatively low heat resistance and impact resistance, an excellent resin material corresponding to the heat resistance is used. For example, ABS is suitable for the back cover 22, and PC is suitable for the substrate cases 134, 136, 138, 141, 143.

Depending on the peripheral conditions, such as when there is a peripheral member in the vicinity of the back cover 22, it is desirable that at least a part of the back cover 22 has a shape along the peripheral member. For example, the front end edge of the bent portion of the back cover 22 is processed into a concave-convex shape in the front-rear direction along the peripheral member on the front side thereof. When the ball tank 48, the guide rail 49, etc. are close to the upper side of the bent portion of the back cover 22, the upper side wall of the bent portion may be inclined in the vertical direction along the bottom surface of the ball tank 48, the guide rail 49. It is processed into an uneven shape.

The hinge shaft 147 of the third hinge means 21 may have a perfect circular shape, an oval shape, or a shape close thereto. The regulatory means 149 can be modified in various ways without impairing its function.

When the hinge shaft 147 is provided with a recess, it is desirable to dispose the recess in a place that is hard to see, such as arranging the recess so as to be located on the front side of the hinge shaft 147 when the back cover 22 is closed. Further, if the back cover 22 is in a non-detachable or difficult state, the concave portion cannot be visually recognized, and if the back cover 22 is opened to a predetermined angle and becomes removable, the concave portion can be visually recognized. Good.

When the inner rail of the guide rail 27 is molded by injection molding, when the length of the inner rail is long, or when a part of other parts is integrally provided on the inner rail, a plurality of inner rails in the longitudinal direction are used. Although the resin pouring portion is provided at the location, it is desirable that the number of the resin pouring portion of the inner rail is one from the viewpoint of preventing the occurrence of weld lines.

When the back cover 22 is provided with heat radiating holes, the shape and number of the heat radiating holes are not a problem as long as the heat radiating holes are suitable for the amount of heat radiated, but they are generally formed in a long hole shape. In this case, it is desirable that the harness arranged inside the back cover 22 is not caught in the heat radiating hole, and a part of the harness does not protrude rearward from the heat radiating hole.

For example, if there is a harness that curves largely to the back cover 22 with a small radius near the inside of the heat dissipation hole, and the curved portion of the harness approaches or contacts the back cover 22, the curved portion of the harness moves in the left-right direction. In the case of, the heat radiation holes are arranged in the vertical direction with respect to the left and right directions, and when the curved portion of the harness is in the vertical direction, the heat radiation holes are arranged in the horizontal direction with respect to the vertical direction.

As shown in Japanese Patent Application Laid-Open No. 2016-144506, a game machine such as a pachinko machine is provided with a game board in the game machine body, and a liquid crystal display means constituting the image display means is provided in the central portion of the game area of the game board. , Game parts such as prize-winning means and movable production means are arranged around the area. On the back side of the game board, an effect board case for accommodating an effect board for various effect control and a liquid crystal substrate case for accommodating a liquid crystal substrate for controlling a liquid crystal display means are arranged on the left and right, and game control is performed on the lower side thereof. A main board case for accommodating the main board for use is arranged.

On the front side of the game machine main body, the upper plate unit on the lower side of the game board is provided with an operation means including an operation button, and if the operation button is operated when a predetermined condition is satisfied during the game, the liquid crystal display means is designated. The operation effect image of is displayed. On the back side of the game machine main body, payout means are arranged in the vertical direction on one side in the left-right direction, and a ball tank for storing game balls and a game ball in the ball tank are guided to the payout means on the upper side. The guide rails are arranged in the left-right direction.

Further, on the back side of the game machine main body, payout means are arranged in the vertical direction on one side in the left-right direction, and a ball tank for storing game balls and a game ball in this ball tank are guided to the payout means on the upper side. The guide rails are arranged in the left-right direction. Further, on the back side of the game machine main body, a power supply board case for accommodating a power supply board for power supply and a payout board case for accommodating a payout board for payout control of game balls are arranged in front and behind under the main board case. Has been done. Further, on the back side of the game machine main body, a back cover that protects the entire effect board case and the liquid crystal board case and the upper side of the main board case from the back side is provided so as to be removable and openable via hinge means.

In this type of gaming machine, the back cover can be opened and closed around the hinge means in consideration of convenience when inspecting the production board case, liquid crystal board case, main board case, and other back member sides, but it is necessary. The entire back cover is removed according to the situation. However, in recent years, the back members of game machines have to be arranged so as to protrude greatly to the back side due to the expansion of the game board, the liquid crystal display means, etc. on the front side thereof, and the arrangement of the movable effect means. is there. Therefore, when the back member, which can be said to be three-dimensional, is protected by the back cover, it cannot be said that simply protecting the back member from the back side in a plane is sufficient, and it is necessary to protect the side surface side of the back member as well.

When removing the back cover under such a situation, it is indispensable to avoid interference with the back member in the back cover. After opening the back cover at a predetermined angle around the hinge means, the hinge shaft of the hinge means It is necessary to remove the back cover by pulling it upward. Therefore, in the back cover under such a situation, it is desired to provide a game machine capable of preventing interference with the back member when the back cover is attached or detached.

<Background technology and issues 2>
Further, in this type of gaming machine, when the gaming machine main body and the back cover are both made of resin, the hinge shaft constituting the hinge means and the hinge shaft are rotatable around the hinge shaft and supported in the vertical direction. Among the hinge bearings, it is conceivable that the hinge shaft is integrally injection-molded on the back cover which is an opening / closing member, and the hinge bearing is integrally injection-molded on the game machine main body which is a support member.

When the hinge shaft is integrally molded with the back cover in this way, in order to secure sufficient strength of the hinge shaft, it is necessary to make the diameter of the hinge shaft larger than the plate thickness on the back cover side. However, if the hinge shaft has a right-cylindrical solid structure and its diameter is larger than the plate thickness on the back cover side, the volume of the molten resin in the solid part of the hinge shaft is larger than the volume of the other parts. Because it is large, the cooling rate of the molten resin in the central part on the hinge shaft side is slower than in other parts, and molding strain (shrinkage strain) called sink marks occurs on the hinge shaft after cooling, causing deformation and backing. It may interfere with the opening and closing of the cover.

If the diameter of the hinge shaft is made the same as the plate thickness on the back cover side, the problem of molding distortion (shrinkage strain) when the molten resin is cooled can be solved, but the strength of the hinge shaft itself is reduced and the back cover is opened and closed. Has an unbearable problem.

In addition, when the hinge shaft is inserted into the hinge bearing, the friction resistance between the hinge shaft and the hinge bearing is small and the back cover can be opened and closed easily as long as the back cover cannot be removed, and the back cover can be removed up to a predetermined angle. When opened, the frictional resistance between the hinge shaft and the hinge bearing increases, and the back cover can be removed, but the hinge shaft does not accidentally come out of the hinge bearing when the back cover is not intended to be removed. It is conceivable to do so.

In such a case, it is necessary to make the cross-sectional shape of the hinge shaft substantially elliptical. However, when the cross-sectional shape of the hinge shaft is made substantially elliptical, the wear of the hinge shaft and / or the hinge bearing is minimized, and the hinge shaft can be inserted and removed from the hinge bearing while ensuring a predetermined frictional resistance. To facilitate it, the hinge shaft needs to be elastically deformable in the major axis direction.

Therefore, in a gaming machine having such a configuration, it is desired to be able to prevent the occurrence of molding distortion while ensuring the strength of the hinge shaft.

<Background technology and issues 3>
Many resin members molded by injection molding, such as operation buttons and back covers, are arranged on the game machine. On the other hand, in molding a resin member, the size of the number of resin pouring portions into which the molten resin is poured into the cavity in the mold greatly affects the aesthetic appearance, strength, and molding efficiency of the resin member after molding. That is, if the number of resin pouring portions of the mold is reduced, the weld line and the traces of the resin pouring portion are reduced, so that the aesthetic appearance and strength of the resin member after molding are improved, but it takes time to pour the molten resin into the cavity. This requires a decrease in molding efficiency, resulting in an increase in manufacturing cost.

On the contrary, if the number of resin pouring portions is increased, the weld lines and the traces of the resin pouring portions are increased, so that the aesthetic appearance and strength of the resin member after molding are lowered, but the molten resin can be easily poured into the cavity. Molding efficiency can be improved and manufacturing cost can be reduced.

Therefore, the number of resin pouring portions is determined in consideration of which part of the game machine the resin member is arranged, such as the first resin member that the player can contact and the second resin member that the player cannot contact. However, it is necessary to balance aesthetics, strength and molding efficiency.

Therefore, in this type of gaming machine, it is desired to ensure a suitable balance of aesthetics, strength and molding efficiency, which are required for each of the first resin member and the second resin member.

<Background technology and issues 4>
On the back side of the game machine, there is a first substrate case which is a main substrate case for accommodating a main substrate, an effect substrate case for accommodating an effect substrate other than the main substrate, a second substrate which is a liquid crystal substrate case for accommodating a liquid crystal substrate, and the like. The case is placed. Each of these board cases is made of transparent resin so that the state of the board inside can be visually recognized.

These substrate cases are molded by an injection molding method, but traces of resin pouring and weld lines cause a decrease in visibility inside the substrate case, and weld lines cause a decrease in the mechanical strength of the substrate case. There's a problem.

In addition, even if the board is used for the same game machine, the main board has a great influence on the result of the whole game, and is easily targeted as a fraudulent target such as illegally replacing the integrated circuit device. The first substrate case for accommodating the substrate is required to have much higher visibility and mechanical strength than the second substrate case for accommodating other sub substrates.

Therefore, in such a game machine, it is desired to improve the visibility of the first substrate case.

<Background technology and issues 5>
In this type of gaming machine, each board case, back cover, and many other resin parts are used. When manufacturing these resin parts, after molding by pouring molten resin from the resin pouring part into the cavity between the fixed mold and the movable mold at high pressure, the movable mold is retracted to open the mold. Then, an injection molding method is adopted in which the resin part is extruded and removed by a plurality of extruded portions on the movable mold side.

When extruding the resin component, the resin component is extruded by simultaneously moving in the extruding direction with the same stroke in a state where a plurality of extruded portions on the movable mold side are in contact with each part of the resin component. Therefore, in the resin part after molding, a plurality of extruded portion traces are left at a plurality of locations corresponding to each extruded portion.

Resin parts such as a substrate case and a back cover have a concavo-convex structure, and the concavo-convex structure portion has a draft according to the amount of the concavo-convex structure so as to be easily removed from the movable mold. However, even with a single resin part, there is a large difference in the degree of adhesion of the resin part to the movable mold between the part with many uneven structures and a complicated shape and the part with few uneven structures and a simple shape. For each target part of the part, it is necessary to arrange an extrusion portion having an optimum size for that part at an optimum position.

Therefore, in such a game machine, it is desired to be able to arrange an extrusion portion having a size suitable for each position of the resin component.

It is made of colorless transparent or colored transparent resin so that the case and the like can be visually recognized and the specific part such as the board management information display unit in each board case can be visually recognized. On the other hand, since the electronic components of the substrate include heat-generating components that generate a large amount of heat, in order to efficiently dissipate the heat, the substrate case and the back cover are provided with a large number of heat dissipation holes at required locations. ..

However, if the substrate case and the back cover have traces of resin pouring parts, heat dissipation holes, etc., light is diffusely reflected at those parts, so that visibility to a specific part is lowered. In addition, if there are through holes such as heat dissipation holes, weld lines are generated on the downstream side of the heat dissipation holes when molding the substrate case and back cover, so the substrate on the substrate side corresponds to the heat dissipation region where many heat dissipation holes are formed. When the management information display unit is arranged, there is a drawback that the display information becomes difficult to see due to the weld line or the like formed on the downstream side of the heat dissipation hole, and the visibility of the display information is lowered.

Therefore, in such a game machine, it is desired to be able to prevent a decrease in visibility when visually recognizing a specific portion on the first member side through the second member.

When molding these substrate cases and back covers with resin, the molten resin is poured into the cavity from the resin pouring portion on the fixed mold side at high pressure to mold, and then the movable mold is retracted to open the mold. Next, the resin part is extruded by the extruded portion on the movable mold side and removed. Therefore, the traces of the resin molding portion such as the trace of the resin pouring portion and the trace of the extruded portion used at the time of molding remain on the substrate case and the back cover.

However, since most of the traces of the resin molding part are uneven, if the traces of the resin molding part overlap with specific parts such as the substrate and the information display part of the substrate case, the light is diffusely reflected at the traces of the resin molding part. Therefore, the trace of the resin molded portion becomes an obstacle and the visibility of the display information and the like from the back side of the back cover is lowered.

Further, if the substrate case, the back cover, etc. have heat dissipation holes, a weld line is generated on the downstream side of the heat dissipation holes when the substrate case and the back cover are molded, so that the substrate corresponds to the heat dissipation region in which a large number of heat dissipation holes are formed.
