Description

[0001]
[Industrial application fields]
The present invention relates to an improvement of a sound effect generating device of a gaming machine control circuit that generates a predetermined sound effect as a game progresses.
[0002]
[Prior art]
A gaming machine is composed of a wide variety of components, and by controlling these with a voice synthesis circuit LSI controlled by a central processing unit, a game with extremely varied contents can be easily provided.
[0003]
In other words, the voice synthesis circuit LSI sequentially executes the control program stored in the memory, so that, in other words, the entire gaming machine operates each component to advance the game, and a predetermined sound effect is generated as the game progresses. Generated.
[0004]
As a result, a game change is given to the player through visual perception, tactile sensation, etc. in addition to the player's hearing. Therefore, in recent years, in order to satisfy the demands of the player, the number of components of the gaming machine that directly touches the sight is increased, and these are operated in a complex manner, and at the same time, control is performed so that sound effects are closely generated. ing.
[0005]
On the other hand, the circuit for controlling the component parts of the gaming machine is inevitably required to increase the mounting density as the number of parts increases as described above. Various designs have been applied to the substrate, such as bonding the circuit wafer directly to the substrate.
[0006]
However, in the present situation, the mounting density is reaching the limit, and the simplification of the configuration of the gaming machine and the reduction in the number of parts are technical issues of the developer.
[0007]
By the way, when developing a gaming machine, it is completed as a product by making improvements so that each component of the gaming machine operates well while debugging each step from both the hardware and software sides at the time of prototyping. Increase the degree.
[0008]
In addition, sound effects are generated according to the progress of the game by the sound source unit provided in the gaming machine, but in recent years, not only the sound quality is good, but also has a variety of tones and advanced musicality. What is rich in change is desired.
[0009]
Therefore, in order to use the real sound for the sound material data, an EP-ROM (or mask ROM) in which the sampled real sound is written is provided in the sound generation unit.
[0010]
The sound material data written in the sound source memory is read out according to the progress of the game by the control unit for controlling the entire gaming machine and appropriately subjected to electronic processing. It is generated as a predetermined sound effect by a sound generator configured together with the sound source memory.
[0011]
The sound generator is composed of an A / D converter for converting sound material data written in the sound source memory into an audio signal, an amplifier circuit for amplifying the converted audio signal and adjusting the tone. ing.
[0012]
A ROM as a sound source memory is rarely mounted directly on a board by soldering. By soldering a socket to a board and attaching / detaching various ROMs to / from the socket, a different sound source memory, that is, a new sound effect Can be exchanged for sound material data.
[0013]
For this reason, during development, experiments on various sound effects are carried out by manual ROM replacement.
[0014]
[Problems to be solved by the invention]
However, the ROM has a dimension of, for example, 32, in order to facilitate handling since the ROM is exchanged manually, even though the wafer is substantially several millimeters square. In the case of a DIP (Dual Inline Package) of pins, the size is 42 mm × 16 mm, and it is difficult to say that the mounting efficiency on the board is good.
[0015]
For this reason, the use of the socket facilitates changing the program specifications by exchanging the ROM, but reduces the mounting area of the electronic component as compared with a means for mounting directly on the substrate such as bonding.
[0016]
For this reason, from the viewpoint of board design, such as the arrangement of electronic components mounted on the board and the routing of lines for electrical connection between each electronic part, the use of sockets has resulted in extremely large development. Since it tends to create the above restrictions, the development period is likely to be prolonged, leading to increased costs.
[0017]
The sound source memory can easily change the specifications of the sound material data by exchanging the ROM. However, depending on the specifications, it may be necessary to change the specifications of the peripheral circuits, particularly the sound generator, and control the sound source, ie, the sound generator memory and the sound generator. When the unit is mounted on the same substrate, the specification of the entire substrate must be changed although only the sound source unit needs to be changed due to the ROM exchange.
[0018]
As a result, the same board on which the components of the sound source unit and the control unit are mounted cannot be used in common among different models of gaming machines, and it is difficult to reduce costs. In addition, if the sound source unit and the control unit are configured separately, only the control unit can be used in common among different models, but the number of parts is increased, which is inconvenient to handle.
[0019]
In addition, since ROM replacement is easy, after the product is shipped, a third party can modify the regular ROM or its peripheral circuit illegally on hardware, or include a ROM that contains illegal control programs and data. It is easy to exchange and it is difficult to reliably prevent such fraud.
[0020]
Therefore, according to the present invention, the sound material data stored in the sound source memory can be easily exchanged and handled easily during development and product manufacture, and a circuit for generating sound effects occupies the control board. Providing sound effect generators for game machine control circuits that reduce the rate as much as possible, thereby reducing restrictions on control board design and protecting legitimate sound source memory after product shipment and making it difficult to cheat It is an object.
[0021]

When at least one of the specifications needs to be changed, the control board can be used in common between different models by replacing only the sound generation board, and the sound generation board is mounted in a direction that intersects the control board. The board extends from the control board surface, and the proportion of the sound generation board occupying the control board can be made extremely small as compared to the case where the sound source component is directly mounted on the control board. By covering the sound source memory with (4), the occurrence of illegal acts on the sound source memory and the peripheral circuits of the sound source memory is suppressed.
[0026]
When the electronic component constituting the sound source memory is an integrated circuit, and the socket (13) to which the integrated circuit is removable is fixed to the sound generation board, the sound source memory can be removed by attaching / detaching the sound source memory to / from the socket.

FIG. 1 shows a main configuration of a sound effect generating device 1 for a gaming machine control circuit according to the present invention. In this embodiment, the sound effect generating device 1 for a game machine control circuit is shown in FIG. The case where it is provided in 2 will be described below.
[0030]
The sound effect generating device 1 of this gaming machine control circuit mainly includes a sound generating board 3 and a covering member 4 shown in FIGS. 3 and 4, and the sound generating board 3 and the covering member 4 control the entire pachinko machine 2. A control circuit (not shown) for mounting is mounted on the control board 5 shown in FIG.
[0031]
The sound generation board 3 is made of a glass epoxy based synthetic resin or the like, and includes an EP-ROM 7, a ROM address latch circuit 8, and a voice synthesis circuit LSI 9 that constitute a sound source unit 6 for generating a plurality of predetermined sound effects.

Based on the sequential execution of the control procedure of the pachinko machine 2 stored in the memory, the pachinko game is advanced, and any sound effect is generated from the sound source unit 6 in accordance with the progress of the pachinko game.
[0033]
On the sound generation board 3, an EP-ROM 7 as a sound source memory, a ROM address latch circuit 8 for accessing the EP-ROM 7, and a voice synthesis circuit LSI 9 as a sound generation unit, as well as chip-like electronic components 12 is distributed and mounted on both surfaces, and these sound sources 7 to 9 and 12 are electrically connected by lines (not shown) routed on the sound generation board 3 to form the sound source unit 6. .
[0034]
The voice synthesis circuit LSI 9 accesses the EP-ROM 7 via the ROM address latch circuit 8, reads each voice data stored at a predetermined address of the EP-ROM 7, and sends a predetermined voice to the speaker ( (Not shown).
[0035]
The sound generation board 3 has an EP-ROM 7 mounted on one surface, and electronic components constituting the ROM address latch circuit 8 and the speech synthesis circuit LSI 9 mounted on the other surface.
[0036]
The EP-ROM 7 is mounted on the sound generation board 3 via a socket 13, and the socket 13 is fixed to the sound generation board 3 by soldering.
[0037]
Thus, since the EP-ROM 7 is detachably attached to the socket 13, the EP-ROM 7 already attached to the socket 13 can be replaced with an EP-ROM 7 for another model according to the specifications of the pachinko game.
[0038]
As shown in FIG. 6, the sound generating board 3 has a plurality of connection pins 14 along one side of the sound generating board 3 as a first connecting part for electrical connection to the control unit 10. The connecting pins 14 are juxtaposed at a predetermined pitch, and the connecting pins 14 protrude along the sound generating board 3 as shown in FIG.
[0039]
On the other hand, the control board 5 is provided with a plurality of connection holes 15 as second connection portions corresponding to each pitch of the connection pins 14. Then, the surface of the connection pin 14 and the periphery of the opening of the connection hole 15 are processed to make it easy to become familiar with the solder 16.
[0040]
A line (not shown) is routed from the control unit 10 to the connection hole 15, and the connection pins 14 are soldered 16 in a state where the connection pins 14 are engaged with the corresponding connection holes 15. In other words, each of the sound source units 6 to 9 and 12 and the control unit 10 are electrically connected.
[0041]
The covering member 4 is for covering at least the EP-ROM 7 (or a mask ROM not shown). In this embodiment, the covering member 4 covers the entire sound generating board 3 mounted on the control board 5. The case where the covering member 4 is mounted on the control board 5 will be described below.
[0042]
The covering member 4 is made of plastic or the like and is formed in a rectangular parallelepiped shape. One side surface of the covering member 4 is opened, and a total of four mounting pins 17 as second mounting portions protrude from corner portions of the open side surface. ing.
[0043]
Specifically, the mounting pins 17 are provided through bosses 18 (see FIG. 1) formed respectively at the corner portions of the covering member 4, and only the tip protrudes from the open side surface of the covering member 4.
[0044]
A first soldering surface 19 is formed at the tip of the mounting pin 17, and the mounting pin 17 engages with a mounting hole 20 as a first mounting portion formed in the control board 5. A second soldering surface 21 is formed around the opening of the mounting hole 20, and when the mounting pin 17 and the mounting hole 20 are engaged, the first soldering surface 19 and the second soldering surface 21 are adjacent to each other.
[0045]
As a result, the first solder processed surface 19 and the second solder processed surface 21 can be easily soldered 16, and the covering member 4 is mounted on the control board 5. In the present embodiment, the mounting holes 20 are formed in four places on the control board 5 so as to surround the connection holes 15, and the pitch of the mounting holes 20 is determined based on the arrangement of the mounting pins 17.
[0046]
Further, on the other side of the covering member 4, in other words, on the bottom surface, a pair of engaging tongue pieces 22 and 22 as first engaging portions are directed inward of the covering member 4 as shown in FIGS. It protrudes like a cantilever.
[0047]
The pair of engaging tongue pieces 22 and 22 are for mounting the sound generating board 3 on the covering member 4. A pair of insertion tongue pieces 22 and 22 are inserted into the base ends of the engaging tongue pieces 22 and 22 on the bottom surface of the covering member 4. While holes 23 and 23 are formed, return steps 24 and 24 are formed at the tips.
[0048]
On the other hand, the sound generating board 3 has a pair of engaging holes (described later) as return step portions 24 and 24 which are detachably engaged with the engaging tongue pieces 22 and 22, respectively. 1 to 6, 11, and 12) 25 and 25 are formed.
[0049]
Further, the pair of engaging tongue pieces 22 and 22 are respectively formed with a pair of release tongue pieces 26 and 26 adjacent to the inside of the both engagement tongue pieces 22 and 22 shown in FIG. Steps 27 and 27 are formed between 26 and 26 and the engaging tongue pieces 22 and 22, respectively.
[0050]
Although the details of the insertion holes 23 and 23 will be described later, the insertion holes 23 and 23 are for releasing the engagement state of the engagement tongue pieces 22 and 22 and the engagement holes 25 and 25, and from the base ends of the release tongue pieces 26 and 26. Tapered surfaces 28 and 28 are formed toward the tip.
[0051]
A pair of guide grooves 29 and 29 are formed along the mounting pins 17 on the inner wall surfaces of the covering member 4 facing each other. The pair of guide grooves 29, 29 are formed to have dimensions that allow sliding on the short side piece of the sound generating board 3 shown in FIGS.
[0052]
A dedicated release member (see FIG. 12) 30 is used to release the engagement state by the engagement tongue pieces 22 and 22 and the engagement holes 25 and 25 described above.
[0053]
The release member 30 includes a pair of release tongues 31, 31 that can be inserted into the insertion holes 23, 23 corresponding to the release tongues 26, 26, and a pair of release stages for pushing out the sound generating board 3. Parts 32 and 32. In the release member 30, the release tongue pieces 31, 31 are formed in parallel with each other, and the release step portions 32, 32 are also formed in parallel with each other.
[0054]
The opening inner diameter of the insertion holes 23 and 23 and the width of the steps 27 and 27, that is, the width of the release tongues 26 and 26, can be easily inserted according to the size of the use site of the release member 30. (See FIG. 8 to be described later).
[0055]
The sound generating board 3 is guided toward the bottom surface of the covering member 4 by the sliding of the side pieces of the sound generating board 3 and the guide grooves 29, 29, and the engagement holes 25, 25 are in the return stage in this guide state. The tips of the portions 24 and 24 are formed at positions where the tips of the portions 24 and 24 are in sliding contact with the surface of the sound generating substrate 3.
[0056]
In the present embodiment, the engagement holes 25, 25 are formed as long holes, the inner diameter dimension in the longitudinal direction is larger than the tip width of the return step sections 24, 24, and the inner diameter dimension in the short direction is set to the return step section 24, The 24 tips are sized so that they can be inserted.
[0057]
As a result, when the sound generating board 3 and the guide grooves 29 and 29 are slid and the tips of the return step portions 24 and 24 come into contact with the side pieces of the sound generating board 3, if the sound generating board 3 is further pressed, The tips of the joint tongues 22 and 22 slidably contact the surface of the sound generating board 3 while getting over the side pieces of the sound generating board 3, and the engaging tongue pieces 22 and 22 eventually smoothly move with respect to the engaging holes 25 and 25. Engaged (see FIGS. 1 and 11).
[0058]
In this state, even if the sound generating board 3 is slid in the direction opposite to that at the time of engagement, the engaging tongue pieces 22 and 22 are locked to the openings of the engaging holes 25 and 25. 3 and the covering member 4 are integrated, and this integrated state is not released.
[0059]
Then, the distal end of the release member 30 for releasing the engagement state by the engagement tongue pieces 22 and 22 and the engagement holes 25 and 25 is inserted into the openings of the insertion holes 23 and 23, and is directly along the tapered surfaces 28 and 28. In FIG. 11, it may be pressed in the direction of arrow A.
[0060]
As a result, the release tongues 26 and 26 formed integrally with the return step portions 24 and 24 are gradually separated from the sound generating substrate 3 while being slid by the release member 30 (see FIG. 12), The portions 24, 24 are disengaged from the engagement holes 25, 25, and the engagement states of the engagement tongue pieces 22, 22 and the engagement holes 25, 25 are released.
[0061]
In the sound effect generator 1 of the gaming machine control circuit configured as described above, the sound source unit 6 includes an EP-ROM 7 and a ROM address latch circuit 8, a voice synthesis circuit LSI 9, and a chip-like electronic component 12. Is divided and mounted on both sides of the sound generation board 3, and if it is necessary to change the specifications of any of the components, the control board 5 can be used in common among different models if only the sound generation board 3 is replaced.
[0062]
When the sound generating board 3 is attached to the control board 5, first, the sound generating board 3 and the guide grooves 29 and 29 are slid while the sound generating board 3 is inserted into the guide grooves 29 and 29 of the covering member 4. By the engagement of the tongue pieces 22 and 22 and the engagement holes 25 and 25, the sound generating substrate 3 and the covering member 4 are integrated as described above.
[0063]
If the sound generating board 3 for another model is mistakenly integrated with the covering member 4, the release tongues 31 and 31 of the exclusive release member 30 are inserted through the insertion holes 23 and 23 from the tip. The engagement state of the tongue pieces 22, 22 and the engagement holes 25, 25 is released.
[0064]
If the release member 30 is further inserted from this state, the release step portions 32 and 32 push out the sound generating board 3 from the covering member 4, so that the sound generating board 3 is removed from the covering member 4 and the removed sound is generated. The substrate 3 is replaced with a regular sound generating substrate 3, and the new sound generating substrate 3 and the covering member 4 are integrated by the same procedure as described above.
[0065]
Of the electronic components mounted on the sound generation board 3, the sound generation board 3 on which the components other than the EP-ROM 7 are mounted in advance is produced in a very large amount in advance, and the pachinko machine 2 according to the production schedule according to the model. If the EP-ROM 7 corresponding to the model is appropriately mounted on the sound generating board 3 and the covering member 4 is soldered to the sound generating board 3, the stock corresponding to the model can be easily managed, and the regular EP- The ROM 7 is protected by the covering member 4.
[0066]
Next, while the integrated sound generating board 3 and the covering member 4 are brought close to the control board 5, each connection pin 14 is engaged with the corresponding connection hole 15, and at the same time, the mounting pin 17 is engaged with the mounting hole 20. Match.
[0067]
After that, the connection pins 14 and the connection holes 15 are soldered 16 so that the sound generation board 3 and the control unit 10 are electrically connected. As a result, the sound generation board 3 is shown in FIG. Are attached in a state of being substantially orthogonal.
[0068]
In this state, since the covering member 4 does not cover the EP-ROM 7, the EP-ROM 7 can be easily replaced, and is easy for software and hardware experiments related to sound effects during development.
[0069]
Further, since the sound generation board 3 is attached to the control board 5 so as to be substantially orthogonal, the sound generation board 3 extends from the control board 5 surface, and the ratio of the sound generation board 3 to the control board 5 is as follows. Compared with the case where the constituent members of the sound source unit 6 are directly mounted on the control board 5, it can be made extremely small.
[0070]
At the same time, the first soldering surface 19 and the second soldering surface 21 are soldered 16 so that the covering member 4 is mounted on the control substrate 5 while covering the sound generating substrate 3. The end is closed by the control board 5 (see FIG. 3).
[0071]
Therefore, the sound generating board 3 is entirely covered with the covering member 4 to protect not only the EP-ROM 7, the ROM address latch circuit 8 and the voice synthesis circuit LSI9 but also their peripheral circuits.
[0072]
In this embodiment, the case where the ROM address latch circuit 8 and the voice synthesis circuit LSI 9 are provided separately has been described. However, some voice synthesis circuits LSI 9 can operate only by processing on hardware. The ROM address latch circuit 8 can be omitted depending on the model of the speech synthesis circuit LSI9.
[0073]
【The invention's effect】
As described above, since the sound generation board is attached in a direction crossing the control board, the proportion of the sound generation board occupying the control board can be extremely small, and the restriction on the design of the control board can be relaxed. , Can prevent the development period from becoming longer.
[0074]
In addition, the covering member protects the sound generating board, thereby preventing the occurrence of fraudulent acts on the sound source memory and the peripheral circuit of the sound source memory, and replacing only the sound generating board even if the specification of the sound source section is changed. Therefore, the control board can be used in common among different models and mass production becomes possible, so cost reduction is easily realized.
[0075]
When the electronic components constituting the sound source memory are composed of integrated circuits, and the sockets to which the integrated circuits can be attached and fixed are fixed to the sound generation board, the electronic components mounted on the sound generation board are previously other than the sound source memory The sound generation board that has been mounted on the sound generator is produced in large quantities in advance, and according to the production schedule of each game machine, the sound source memory corresponding to the model is appropriately mounted on the sound generation board, and the covering member is the sound generation board If the soldering is performed, the stock corresponding to the model can be easily managed, and the regular sound source memory is protected by the covering member.
[0076]
A first mounting portion is formed on the control board, a second mounting portion that engages with the first mounting portion, and a first engagement portion for mounting the sound generating substrate are formed on the covering member. When the second engagement portion that is detachably engaged with the first engagement portion is formed, the covering member is attached to the sound generation board by the engagement of the first engagement portion and the second engagement portion. The covering member can be removed by releasing the engagement state between the first engaging portion and the second engaging portion, and the covering member is controlled by the engagement of the first mounting portion and the second mounting portion. By attaching to the board, it is possible to suppress the occurrence of fraudulent acts on the sound source memory and the peripheral circuit of the sound source memory.
[0077]
When an insertion hole for inserting a release member for releasing the engagement state by the first engagement portion and the second engagement portion is formed in at least one of the covering member and the control board, the release member is formed in the insertion hole. By inserting the, the engagement state between the first engagement portion and the second engagement portion can be released, and a reduction in workability during product assembly is suppressed.
