  8 to 10 show a configuration example of the receptacle KRE1. FIG. 8A is a perspective view showing the left rear as viewed obliquely from below. FIG. 8 (B) is a perspective view showing a state of the left rear as viewed from obliquely above. FIG. 9 is a rear view showing a state in which the vicinity of the receptacle KRE 1 outside the cover member 802 is viewed from the rear side (rear side). FIG. 10 is a cross-sectional view showing the vicinity of the receptacle KRE1 as viewed from the lower side. The receptacle KRE1 includes a housing in which the insertion port OP1 is formed, and terminals TA01 to TA03.

  The insertion opening OP1 is an opening portion into which a connector plug provided on the main substrate wiring can be inserted and attached. The terminals TA01 to TA03 are made of metal such as copper, for example, and correspond to the plurality of terminals provided on the connector plug when the connector plug of the main board wiring is inserted into the insertion port OP1. It is a metal member which is in electrical contact with the terminal placed at the position. In the receptacle KRE 1, terminals TA 01 and TA 03 serving as a pair of ground terminals are surface-mounted on the substrate of the effect control board 12 at positions sandwiching both sides of the terminal TA 02 serving as a signal terminal. In the main substrate wiring, ground lines serving as a pair of ground voltage lines may be provided at positions sandwiching both sides of the signal line serving as the signal transmission line. Alternatively, even if the coaxial cable is used as the main board wiring, the inner conductor of the coaxial cable is electrically connected to the terminal TA02, and the outer conductor of the coaxial cable is electrically connected to the terminals TA01 and TA03. Good.

  The receptacles KRE1 can be joined to connection pads provided on the effect control substrate 12 (first substrate 12A) with the terminals TA01 to TA03 drawn out on the side surface PL1 to be the terminal arrangement surface. The method of bonding the terminal to the connection pad may be a metal bonding method using solder or the like, or may be an adhesive bonding method such as conductive resin bonding or anisotropic conductive member bonding. Fixing brackets SS01 and SS02 are provided on the side of the side surface PL2 which is the back side of the side surface PL1.

  In the cover member 802 of the substrate case 800, of the connector openings 836, the opening area 836a formed corresponding to the receptacle KRE1 has a narrower opening width than the opening area formed corresponding to the other receptacles. It may be formed to be Each of the terminals TA01 to TA03 of the receptacle KRE1 is formed to have an exposed portion exposed from the substrate case 800 in the opening region 836a and a covered portion which is covered by the substrate case 800 and not exposed. For example, in the terminals TA01 to TA03, the tip end portion joined to the corresponding connection pad may be included in the covering portion which is covered by the cover member 802 of the substrate case 800 and is not exposed.

  If the component housing portion 802a and the opening peripheral portion 840 forming the inner peripheral wall surface 836b to be the inner end surface in the opening region 836a are integrally formed on the cover member 802 of the substrate case 800 via the sloped portion 821e1. Good. The component storage portion 802 a is formed so as to be able to store at least a part of the electrical components mounted on the effect control substrate 12. In the opening region 836a, the distance between the inner peripheral wall surface 836b and the receptacle KRE1 is such that the distance between the inner peripheral wall surface 836b far from the component storage portion 802a and the side surface PL2 of the receptacle KRE1 is the opening width W1. An opening width W2 is a distance between the near inner peripheral wall surface 836b and the side surface PL1 which is a terminal disposition surface of the receptacle KRE1. The arrangement of the opening area 836a and the receptacle KRE1 may be adjusted so that the opening width W2 is wider than the opening width W1. In the terminals TA01 to TA03 of the receptacle KRE1, the tip end portion which is a mounting position joined to the corresponding connection pad and mounted on the surface is covered by the opening peripheral portion 840 forming the inner peripheral wall surface 836b in the opening region 836a. A space SP1 as a space is formed near the mounting position of the receptacle KRE1 by the opening peripheral portion 840 of the cover member 802 and the substrate surface of the effect control board 12.

  The terminal TA01 is bonded to the dummy pad DP1 provided on the effect control substrate 12. The terminal TA03 is bonded to the dummy pad DP2 provided on the effect control substrate 12. The terminals TA01 and TA03 are joined to the connection pad GPA1. The connection pad GPA1 may be connected to the wiring layer LY4 in which the wiring pattern for grounding is formed through the through holes provided in the effect control substrate 12. In the section of the effect control board 12 shown in FIG. 10, the wiring layer LY2 is formed between the insulating layer LY1 and the insulating layer LY3, and the surface on which the receptacle KRE1 is surface mounted is protected using, for example, polyimide. It is sufficient if the layer LY0 is formed. As described above, the wiring pattern in the effect control substrate 12 may be formed in the wiring layer LY2 provided between the insulating layer LY1 and the insulating layer LY3 serving as the inner layer in the substrate of the effect control substrate 12. Alternatively, the wiring pattern in the effect control board 12 may be formed on the surface of the effect control board 12. The terminal TA02 is joined to a connection pad electrically connected to the wiring pattern for signal transmission.

  The fixing bracket SS01 provided in the receptacle KRE1 is joined to a dummy pad DP3 provided on the effect control board 12. The fixing bracket SS02 provided in the receptacle KRE1 is joined to the dummy pad DP4 provided on the effect control substrate 12. Thus, on the side of the side surface PL2 on the back side of the side surface PL1 where the terminals TA01 to TA03 are arranged, the fixing brackets SS01 and SS02 are provided on the substrate of the effect control substrate 12, and dummy pads DP3 and DP4. It is sufficient to be bonded to the

  While the presentation control command is transmitted from the main substrate 11 to the presentation control substrate 12, there may be only one signal line serving as a signal transmission line in the main substrate wiring for transmitting the command. . Corresponding to this, in receptacle KRE1 surface-mounted on the board of effect control board 12, a case where only terminal TA02 used as a signal terminal is provided is also considered. In this case, the area of the bonding surface of the effect control board 12 on the substrate according to the lateral width and depth of the receptacle KRE1 corresponds to the protrusion amount of the effect control board 12 from the substrate surface according to the height of the receptacle KRE1. Since it becomes easy to reduce, there exists a possibility that it may become impossible to fully ensure the joint intensity by surface mounting of receptacle KRE1. Therefore, in the receptacle KRE 1, the terminals TA 01 and TA 03 serving as a pair of ground terminals are surface-mounted on the substrate of the effect control board 12 at positions sandwiching both sides of the terminal TA 02 serving as a signal terminal. As a result, an appropriate substrate configuration that can sufficiently ensure the bonding strength by surface mounting of the receptacle KRE 1 is possible. Further, since both sides of the terminal TA02 serving as a signal terminal are sandwiched between the terminals TA01 and TA03 serving as a pair of ground terminals, an appropriate substrate configuration that is less susceptible to noise can be realized.

  In the receptacle KRE1, the terminal TA01 is joined to the dummy pad DP1 provided on the substrate of the effect control board 12, and the terminal TA03 is joined to the dummy pad DP2 provided on the substrate of the effect control board 12. Further, tip portions of the terminals TA01 to TA03 are disposed so as to be covered by the cover member 802 of the substrate case 800. As described above, since the terminals TA01 and TA03 are bonded to the dummy pads DP1 and DP2, it is possible to achieve an appropriate substrate configuration capable of sufficiently securing the bonding strength by surface mounting of the receptacle KRE1. Since the tips of the terminals TA01 to TA03 are covered with the cover member 802 of the substrate case 800, an appropriate substrate configuration that can protect important portions in surface mounting, such as the junctions between the terminals and the substrate surface, is possible. Note that the terminal TA 02 that is to be a signal terminal may be bonded to the dummy pad or may not be bonded to the dummy pad. The signal deterioration due to the influence of the conductor shape may be prevented by preventing the terminal TA 02 serving as the signal terminal from being bonded to the dummy pad.

  In receptacle KRE1, fixing bracket SS01 is joined to dummy pad DP3 provided on the board of effect control board 12 on the side of side PL2 on the back side of side face PL1 on which terminals TA01 to TA03 are arranged, and fixed. The metal fitting SS02 is bonded to the dummy pad DP4 provided on the effect control substrate 12. As described above, since the fixing brackets SS01 and SS02 are joined to the dummy pads DP3 and DP4, it is possible to provide an appropriate substrate configuration capable of sufficiently securing the joint strength by surface mounting of the receptacle KRE1. In addition, any fixing method such as bonding a fixing member using a synthetic resin similar to that of the housing of the receptacle KRE 1 onto a substrate is possible regardless of the method of bonding metal members such as fixing brackets SS01 and SS02 onto the substrate. Any member may be used as long as the member can be bonded onto the substrate.

  The component housing portion 802a of the cover member 802 of the substrate case 800 is formed so as to be able to receive at least a part of the electric components mounted on the substrate of the effect control substrate 12, and the inner peripheral wall surface 836b in the opening region 836a and the receptacle KRE1. The opening width W2 of the side close to the component storage portion 802a is formed wider than the opening width W1 of the far side. The side close to the component storage portion 802a is the side of the side surface PL1 which is a terminal disposition surface on which the terminals TA01 to TA03 are drawn out in the receptacle KRE1. On the other hand, the side far from the component storage portion 802a is the side of the side face PL2 which is the back side of the terminal arrangement face in the receptacle KRE1. Therefore, the distance between inner peripheral wall surface 836b and receptacle KRE1 in opening region 836a is the opening width on the side corresponding to side PL2 where the opening width W2 on the side corresponding to side PL1 serving as the terminal arranging face corresponds to the back surface It is formed wider than W1. The adjusted opening width enables, for example, an appropriate substrate configuration that allows the cover member 802 to be easily attached, removed, or aligned. In addition, an appropriate board configuration that can suppress damage due to a collision between the terminal arrangement surface of the receptacle KRE1 and the cover member 802 at the time of attachment or removal of the cover member 802 is possible.

  Each of the terminals TA01 to TA03 of the receptacle KRE1 is not covered by the cover member 802 of the substrate case 800 in the opening area 836a, and an exposed part exposed and a cover part not covered by the cover member 802 of the substrate case 800 are formed. Ru. As described above, unlike the exposed portion, each of the terminals TA01 to TA03 is provided with a covered portion which is covered and not exposed, so that important portions in surface mounting can be protected, such as a joint portion between the terminal and the substrate surface. Appropriate substrate configuration is possible.

  In the terminals TA01 to TA03 of the receptacle KRE1, the mounting position surface-mounted to be bonded to the corresponding connection pad on the effect control substrate 12 is the opening of the cover member 802 forming the inner peripheral wall surface 836b in the opening region 836a. It is covered by the rim 840. Then, a space SP1 close to the mounting position of the receptacle KRE1 is formed by the opening peripheral edge portion 840 of the cover member 802 and the substrate surface of the effect control substrate 12. As described above, since the opening peripheral portion 840 of the cover member 802 and the substrate surface of the effect control substrate 12 are arranged so as to be position adjustable, an appropriate substrate configuration capable of protecting the mounting position of the receptacle KRE1 is possible.

  FIG. 11A shows a transmission path corresponding to the main substrate wiring. As shown in FIG. 11A, the signal SCD supplied to the terminal TA 02 in the main substrate wiring receptacle KRE 1 is input to the effect control CPU 120 via the input driver circuit 130. The terminals TA01 and TA03 of the receptacle KRE1 are grounded (connected to the ground line).

  FIG. 11B shows a transmission path corresponding to the power supply substrate wiring. The receptacle KRE2 for power supply substrate wiring includes terminals TA11 to TA30. Among these, in the receptacle KRE2, the terminals TA11 and TA12 corresponding to the outside and the terminals TA29 and TA30 are all grounded (connected to the ground line). In addition to the terminals TA11, TA12, TA29, and TA30, the terminals TA25 and TA26 are grounded (connected to the ground line). A power supply voltage VSL2 of 34 V DC is supplied to the terminals TA13 and TA14 of the receptacle KRE2. A power supply voltage VDD2 of 12 V DC is supplied to the terminals TA15 to TA20 of the receptacle KRE2. A power supply voltage VCC2 of 5 V DC is supplied to the terminals TA21 to TA24 of the receptacle KRE2. A power supply voltage VDD3 of DC 12 V is supplied to the terminals TA27 and TA28 of the receptacle KRE2.

  Power supply voltage VSL2 of direct current 34 V supplied from power supply substrate 92 to effect control substrate 12 via power supply substrate wiring connected to receptacle KRE2 for power supply substrate wiring is output from effect control substrate 12 as power supply voltage VSL as it is The driver substrate 19 is supplied via the driver substrate wiring connected to the receptacle KRE 3 for driver substrate wiring. For example, in receptacle KRE2 for power supply substrate wiring, terminals TA13 and TA14 receiving supply of power supply voltage VSL2 are connected to power supply line LSL, and power supply line LSL is connected to a predetermined terminal in receptacle KRE3 for driver substrate wiring . As shown in FIG. 4, receptacle KRE 2 for power supply substrate wiring is provided adjacent to receptacle KRE 3 for driver substrate wiring, and power supply line LSL does not approach main electric circuits or electrical parts in effect control substrate 12. It may be arranged to pass through the end of the substrate 12.

  FIG. 12 shows the transmission path of the power supply voltage VSL. In the power supply substrate 92, a power supply voltage VSL2 of DC 34 V is generated from a commercial power supply which is an external power supply, using the transformer circuit 501, the DC voltage generation circuit 502, and the like. For example, in the transformer circuit 501, a power supply voltage of 24 V AC is generated. The DC voltage generation circuit 502 includes a rectification circuit and a smoothing circuit, and rectifies and smoothes a power supply voltage of 24 V AC to generate a power supply voltage VSL2 of 34 V DC. The power supply voltage VSL2 of 34 V DC is not controlled by feedback control or the like, so the power supply voltage VSL2 of 34 V DC also fluctuates due to the fluctuation of the power supply voltage of 24 V AC. As described above, the power supply voltage VSL2 of 34 V DC supplied to the terminals TA13 and TA14 of the receptacle KRE2 is a DC voltage with a large fluctuation range (ripple component) in which voltage control is not performed. On the other hand, the power supply voltage VDD2 of DC 12 V supplied to the terminals TA15 to TA20 of the receptacle KRE2, the power supply voltage VCC2 of DC 5 V supplied to the terminals TA21 to TA24 of the receptacle KRE2, and the terminals TA27 and TA28 of the receptacle KRE2 The power supply voltage VDD3 of 12 V DC is voltage controlled by feedback control in the power supply substrate 92, and may be a DC voltage having a smaller fluctuation range (ripple component) compared to the power voltage VSL of 34 V DC. .

  In the effect control board 12, the power supply line LSL corresponding to the power supply voltage VSL of DC 34 V does not interpose the stabilization circuit for stabilizing the voltage such as the filter circuit. On the other hand, in the driver substrate 19, the power supply voltage VSL of DC 34 V is input to the filter circuit 511 to stabilize the voltage. Further, in the effect control board 12, a stabilization circuit for stabilizing the voltage by a filter circuit or the like intervenes on the power supply line corresponding to the power supply voltage different from the power supply voltage VSL of 34 V DC.

  For example, in receptacle KRE2 for power supply substrate wiring, terminals TA15 to TA20 to which power supply voltage VDD2 of 12 V DC is supplied are connected to filter circuit 131a, and terminals TA21 to TA24 to which power supply voltage VCC2 of 5 V DC is supplied are filter The terminals TA 27 and TA 28 connected to the circuit 131 b and supplied with the power supply voltage VDD 3 of 12 V DC are connected to the filter circuit 131 c. The output portion of the filter circuit 131a is connected to a power supply line LDS supplying a 12 V DC power supply voltage VDS, and the output portion of the filter circuit 131b is connected to a power supply line LCC supplying a 5 V DC power supply voltage VCC. The output unit is connected to a power supply line LDC that supplies a power supply voltage VDC of 12 V DC. Thus, filter circuit 131a is interposed between terminals TA15-TA20 of receptacle KRE2 and power supply line LDS corresponding to power supply voltage VDS of 12 V DC, and filter circuit 131b is the power supply voltage of terminals TA21-TA24 of receptacle KRE2 and DC 5 V The filter circuit 131c intervenes between the terminals TA27 and TA28 of the receptacle KRE2 and the power supply line LDC corresponding to the power supply voltage VDC of 12 V DC.

  The power supply line LSL is provided to supply a 34 V DC power supply voltage VSL. The power supply line LDS is provided to supply a 12 V DC power supply voltage VDS. The power supply line LCC is provided to supply a power supply voltage VCC of 5 V DC. The power supply line LDC is provided to supply a power supply voltage VDC of 12 V DC. Therefore, the power supply line LSL not including the filter circuit is provided to supply a high power supply voltage as compared with any of the power supply lines LDS, LCC, and LDC in which the filter circuit is interposed.

  In the receptacle KRE2, six terminals TA15 to TA20 to which the power supply voltage VDD2 of 12 V DC is supplied, four terminals TA21 to TA24 to which the power supply voltage VCC2 of 5 V DC is supplied, and two power supplies VDD3 of 12 V DC are supplied While the terminals TA27 and TA28 are provided, two terminals TA13 and TA14 to which a 34 V DC power supply voltage VSL2 is supplied are provided. Therefore, in the receptacle KRE2, among the terminals to which the power supply voltage is supplied, the terminals TA15 to TA20, TA21 to TA24, TA27, and TA28 connected to the filter circuit are not connected to the filter circuit. It becomes more than the number of terminals of TA14. The number of terminals corresponding to each power supply voltage may be set according to the power supply capacity and the load current.

  In receptacle KRE2, power supply voltage VDD2 of DC 12 V is supplied to terminals TA15 to TA20, power supply voltage VCC2 of DC 5 V is supplied to terminals TA21 to TA24, and power supply voltage VDD3 of DC 12 V is supplied to terminals TA27 and TA28. Thus, a power supply voltage VSL2 of 34 V DC is supplied to the terminals TA13 and TA14. A filter circuit 131a intervenes between the terminals TA15 to TA20 of the receptacle KRE2 and the power supply line LDS supplying the power supply voltage VDS of 12 V DC to supply the terminals TA21 to TA24 of the receptacle KRE2 and the power supply voltage VCC of 5 V DC. A filter circuit 131b intervenes between the power supply line LCC and the power supply line LCC, and a filter circuit 131c intervenes between the terminals TA27 and TA28 of the receptacle KRE2 and the power supply line LDC supplying the power supply voltage VDC of 12 V DC. On the other hand, no filter circuit intervenes between the terminals TA13 and TA14 of the receptacle KRE2 and the power supply line LSL supplying the power supply voltage VSL of 34 V DC. Thus, the power supply lines LDS, LCC, and LDC in which the filter circuit intervenes can supply a plurality of types of power supply voltages such as DC 12 V and DC 5 V, and the power supply line LSL in which the filter circuit is not interposed is one type of DC 34 V Power supply voltage can be supplied. In the receptacle KRE2, the terminals TA13 and TA14 are disposed outside the terminals TA15 to TA24 and the like. Alternatively, the receptacle KRE2 includes, among the terminals TA15 to TA24, TA27, and TA28, a terminal disposed inside the terminals TA13 and TA14, such as the terminals TA15 to TA24.

  In the receptacle KRE2, the terminals TA13 to TA24, TA27, and TA28 are disposed between the terminals TA11 and TA12 and the terminals TA29 and TA30. The terminals TA13 to TA24, TA27, and TA28 are all terminals to which a power supply voltage is supplied, and serve as power supply voltage terminals connected to various power supply voltages. On the other hand, the terminals TA11 and TA12 and the terminals TA29 and TA30 are terminals to which no power supply voltage is supplied, and serve as ground terminals connected to the ground voltage. Therefore, in the receptacle KRE2, the terminals TA13 to TA24, TA27 and TA28 to be power supply voltage terminals are arranged between the terminals TA11 and TA12 to be ground terminals and the terminals TA29 and TA30.

  In receptacle KRE2, terminals TA13 and TA14 and terminals TA15 to TA24 are disposed between terminals TA11 and TA12 and terminals TA25 and TA26, and between terminals TA25 and TA26 and terminals TA29 and TA30 TA27 and TA28 are arranged. The terminals TA13 and TA14 are terminals to which a power supply voltage VSL2 of 34 V DC is supplied, and are power supply voltage terminals connected to the power supply voltage VSL2. The terminals TA15 to TA20 are terminals to which a power supply voltage VDD2 of 12 V DC is supplied, and are power supply voltage terminals connected to the power supply voltage VDD2. The terminals TA21 to TA24 are terminals to which a power supply voltage VCC2 of 5 V DC is supplied, and are power supply voltage terminals connected to the power supply voltage VCC2. The terminals TA27 and TA28 are terminals to which a power supply voltage VDD3 of 12 V DC is supplied, and are power supply voltage terminals connected to the power supply voltage VDD3. Therefore, terminals TA13 and TA14 as power supply voltage terminals connected to power supply voltage VSL2 of DC 34 V and terminals TA15 to TA24, TA27, TA28 as power supply voltage terminals connected to power supply voltage other than power supply voltage VSL2 of DC 34 V The terminals TA15 to TA24, which are a part of the above, are disposed between the terminals TA11 and TA12 serving as the ground terminals and the terminals TA25 and TA26. Further, among the terminals TA15 to TA24, TA27, and TA28 as power supply voltage terminals connected to a power supply voltage other than the power supply voltage VSL2 of DC 34V, terminals TA27 and TA28, which are other parts, become ground terminals. It is disposed between TA 25 and TA 26 and terminals TA 29 and TA 30.

  The 12 VDC power supply voltage VDD3 supplied to the terminals TA27 and TA28 is used by the step-down converter circuit 132 to generate a 1.05 VDC DC power supply voltage. The power supply voltage of DC 1.05 V is supplied to a specific microprocessor, such as a graphics processor of the display control unit 123, for example. Therefore, in the receptacle KRE2, of the terminals TA13 to TA24, TA27, and TA28 connected to the power supply voltage, the terminals TA13 and TA14 connected to the power supply voltage VSL2 having a relatively large fluctuation width (ripple component) 34V are The display control unit 123 is disposed farthest from TA 27 and TA 28 connected to a power supply voltage VDD 3 of DC 12 V used to generate a power supply voltage to be supplied to a specific microprocessor such as a graphics processor.

  In the effect control board 12, it is conceivable that the power supply voltage VSL2 of 34 V DC is stabilized and then output as the power supply voltage VSL. However, in the effect control board 12, the installation of the circuit element for stabilizing the power supply voltage VSL2 of direct current 34 V which has no direct application causes an increase in the number of parts and the substrate volume, and the power loss and the manufacturing cost also increase. In addition, the installation of special circuit elements may make it difficult to reuse and commonize the effect control board 12. Therefore, the power supply voltage VSL2 of direct current 34 V for which voltage control is not performed is output from the effect control board 12 as the power supply voltage VSL as it is, and is input to the filter circuit 511 by the driver board 19 to stabilize the voltage. This enables an appropriate substrate configuration that prevents the increase in the number of parts and the substrate volume, and the power loss and the manufacturing cost. In addition, an appropriate substrate configuration can be realized in which reuse and sharing of the effect control substrate 12 are easily performed. In addition, the power supply line LSL is disposed away from the main electric circuits and electric parts in the effect control board 12, so that an appropriate board configuration is provided to prevent the adverse effect of noise due to the DC voltage having a large fluctuation width (ripple component). It will be possible.

  In the effect control board 12, the power supply line LSL supplying the power supply voltage VSL of DC 34 V is the power supply line LDS supplying the power supply voltage VDS of DC 12 V, the power supply line LCC supplying the power supply voltage VCC of DC 5 V, the power supply of DC 12 V It supplies DC 34 V, which is a high power supply voltage, as compared with any of the power supply lines LDS that supply the voltage VDS. In general, a stabilization circuit that stabilizes a high power supply voltage tends to have larger circuit element volume and power loss than a stabilization circuit that stabilizes a low power supply voltage, and the cost of the circuit element is expensive. It is easy to be a thing. Therefore, since no filter circuit intervenes in the power supply line LSL for supplying the power supply voltage VSL of DC 34 V, which is a high power supply voltage, an appropriate substrate configuration capable of preventing an increase in substrate volume, an increase in power loss and manufacturing cost is possible. become.

  In the receptacle KRE2, a power supply voltage VSL of 34 V DC is supplied to the two terminals TA13 and TA14. On the other hand, in receptacle KRE2, power supply voltage VDD2 of DC 12 V is supplied to six terminals TA15 to TA20, power supply voltage VCC2 of DC 5 V is supplied to four terminals TA21 to TA24, and two terminals TA27 and TA28 Is supplied with a power supply voltage VDD3 of DC 12V. Therefore, in the effect control board 12, among the terminals to which the power supply voltage is supplied in the receptacle KRE2, the number of terminals TA15 to TA24, TA27, TA28 connected to any of the filter circuits 131a to 131c is the filter circuit The number of terminals TA13 and TA14 not connected to is larger than the number of terminals. Since the number of terminals is set in this manner, an appropriate board for improving the degree of freedom in wiring design according to the application of the power supply voltage and the power supply capacity to be stabilized in the effect control board 12, for example. Configuration is possible.

  In the receptacle KRE2, among the terminals to which the power supply voltage is supplied, the terminals TA15 to TA24, TA27 and TA28 connected to any of the filter circuits 131a to 131c in the effect control board 12 have a power supply voltage VDD2 of 12 V DC. It includes terminals TA15 to TA20 which can be supplied, terminals TA21 to TA24 which can supply a power supply voltage VCC2 of 5 V DC, and terminals TA27 and TA28 which can supply a power supply voltage VDD3 of 12 V DC. On the other hand, in the receptacle KRE2, among the terminals to which the power supply voltage is supplied, the terminals TA13 and TA14 not connected to the filter circuit in the effect control board 12 can supply the power supply voltage VSL2 of DC 34 V, and other types Supply voltage is not supplied. Therefore, the number of types of power supply voltages that can be supplied differs depending on whether the power supply line includes the filter circuit or the power supply line does not include the filter circuit. More specifically, the power supply line through which the filter circuit intervenes can supply a plurality of types of power supply voltages such as a power supply voltage VDD2 of DC 12 V, a power supply voltage VCC2 of DC 5 V, and a power supply voltage VDD2 of DC 12 V. The power supply line where there is no intervening can supply one kind of power supply voltage of 34 V DC as the power supply voltage VSL. As described above, since the number of types of power supply voltages that can be supplied is different corresponding to the power supply line, for example, according to the application of the power supply voltage for which the voltage is stabilized in the effect control board 12, freedom of wiring design An appropriate substrate configuration can be made to improve the degree.

  The terminals TA13 and TA14 connected to the power supply line not including the filter circuit are disposed outside the terminals TA15 to TA24 and the like connected to the power supply line including the filter circuit. Such an arrangement of the terminals enables an appropriate substrate configuration that improves the degree of freedom in wiring design according to, for example, the application of the power supply voltage for which the voltage is to be stabilized in the effect control substrate 12. In addition, an appropriate substrate configuration can be achieved in which the wiring length for outputting the power supply voltage VSL2 of direct current 34 V supplied to the terminals TA13 and TA14 to the driver substrate 19 as the power supply voltage VSL as it is can be shortened.

  In the receptacle KRE2, the terminals TA13 to TA24, TA27, and TA28 are power supply voltage terminals connected to various power supply voltages. On the other hand, in the receptacle KRE2, the terminals TA11 and TA12 and the terminals TA29 and TA30 are all ground terminals connected to the ground voltage. The terminals TA13 to TA24, TA27, and TA28 are disposed between the terminals TA11 and TA12 and the terminals TA29 and TA30. Such an arrangement of terminals enables an appropriate substrate configuration that is less susceptible to noise. In addition, it is possible to shield the power supply voltage and to make an appropriate substrate configuration that prevents the occurrence of noise.

  In the receptacle KRE2, the terminals TA15 to TA24, TA27, and TA28 become first power supply voltage terminals connected to a power supply voltage different from the power supply voltage VSL2 of 34 V DC. On the other hand, in the receptacle KRE2, the terminals TA13 and TA14 become second power supply voltage terminals connected to the power supply voltage VSL2 of 34 V DC. In the receptacle KRE2, the terminals TA11 and TA12 are the first ground terminals connected to the ground voltage, the terminals TA25 and TA26 are the second ground terminals connected to the ground voltage, and the terminals TA29 and TA30 are connected to the ground voltage Third ground terminal. In receptacle KRE2, terminals TA13 and TA14 included in the second power supply voltage terminal and terminals TA15 to TA24 included in the first power supply voltage terminal are included in the first ground terminal, and terminals TA11 and TA12, and the second The terminals TA27 and TA28 disposed between the terminals TA25 and TA26 included in the ground terminal and included in the first power supply voltage terminal are included in the terminals TA25 and TA26 included in the second ground terminal and the third ground terminal It is disposed between the terminals TA29 and TA30. Such an arrangement of terminals enables an appropriate substrate configuration that is less susceptible to noise. In particular, the terminals TA25 and TA26 included in the second ground terminal are included in the terminals TA13 and TA14 included in the second power supply voltage terminal and the terminals TA15 to TA24 included in the first power supply voltage terminal and the first power supply voltage terminal. The arrangement between the TA 27 and the TA 28 enables an appropriate substrate configuration that is less susceptible to noise. In addition, it becomes possible to shield the power supply voltage efficiently, and to prevent the generation of noise. In addition, terminals TA13 and TA14 connected to the DC 34V power supply voltage VSL2 are connected to the DC 12V power supply voltage VDD3 used to generate the power supply voltage supplied to a specific microprocessor such as the graphics processor of the display control unit 123 Because they are located away from the TA 27 and TA 28 that are to be placed, it is possible to have an appropriate substrate configuration that makes certain microprocessors less susceptible to noise.

  In the effect control board 12, the power supply voltage VDL is branched at the branch point DB1 from the power supply voltage VDD2 supplied at the terminals TA15 to TA20 of the receptacle KRE2. After the power supply voltage VDL is branched at such a branch point DB1, the power supply voltage VDS is stabilized by the filter circuit 131a. The power supply voltage VDL is a DC 12 V power supply voltage used to drive a specific electrical component, such as a specific LED included in the effect LED 61, for example. The power supply voltage VDS is a DC 12 V power supply voltage which is supplied to the amplifier circuit 521 and used to output an audio signal. Thus, the filter circuit 131a stabilizes the power supply voltage VDS after branching the power supply voltage VDD2 of 1 into the power supply voltage VDL and the power supply voltage VDS. The effect control board 12 may be provided with an amplification circuit 521, and may output audio signals supplied to the speakers 8L and 8R.

  FIG. 13A shows the relationship between the wire lengths of the wires for supplying the power supply voltage VDS. In the effect control board 12, the power supply line LDS for supplying the power supply voltage VDS to the amplifier circuit 521 has a wiring length LL1 from the branch point DB1 to the input part of the filter circuit 131a and the output part of the filter circuit 131a. A wire having a wire length LL2 to the input portion of the amplifier circuit 521 may be included. The wiring length LL2 may be adjusted so that the arrangement of the wirings and circuits in the effect control board 12 is shorter than the wiring length LL1. Thus, the wiring length LL2 from the filter circuit 131a to the amplifier circuit 521 becomes shorter than the wiring length LL1 to the filter circuit 131a after the power supply voltage VDS is branched at the branch point DB1. The amplification circuit 521 and the filter circuit 131 a are not limited to those installed on the effect control board 12, and may be installed on the voice control board 13.

  FIG. 13B shows the transmission path of the power supply voltage VDS when the amplifier circuit 521 and the filter circuit 131 a are installed on the voice control board 13. In the power supply substrate 92, a power supply voltage VDD2 of DC 12 V is generated from a commercial power supply which is an external power supply, using the transformer circuit 501, the DC voltage generation circuit 502 and the like. The power supply voltage VDD2 of DC 12 V is supplied to the terminals TA15 to TA20 in the receptacle KRE2 for power supply substrate wiring. In the effect control board 12, after the power supply voltage VDL is branched at the branch point DB1 from the power supply voltage VDD2 supplied from the terminals TA15 to TA20 of the receptacle KRE2, it is outputted from the effect control board 12 as the power supply voltage VDS as it is. The voice control board 13 may be supplied via the voice control board wire connected to the receptacle KRE 4 for voice board wiring. For example, in receptacle KRE2 for power supply substrate wiring, terminals TA15 to TA20 receiving supply of power supply voltage VDD2 are connected to power supply line LDS, and power supply line LDS is connected to a predetermined terminal in receptacle KRE4 for voice control substrate wiring. Just do it. In the effect control board 12, the power supply line LDS corresponding to the power supply voltage VDS of direct current 12 V may not have a stabilization circuit for stabilizing the voltage such as the filter circuit. On the other hand, in the voice control board 13, the power supply voltage VDS of DC 12 V is input to the filter circuit 131a to stabilize the voltage. The power supply voltage VDS thus stabilized may be supplied to the amplifier circuit 521.

  The voice control board 13 may be provided with a voice control IC 522, a voice data ROM 523 and the like. The voice control IC 522 executes signal processing for generating voice and sound effects in accordance with a command (such as sound number data) output from the effect control CPU 120 of the effect control board 12 or the like. The voice data ROM 523 stores control data corresponding to the sound number data. The control data corresponding to the sound number data is a collection of data indicating in time series the output mode of the sound and the sound effect in a predetermined period (for example, a variable display period of a decorative symbol). The various configurations provided on the voice control board 13 may be configured to be provided on the effect control board 12 without the voice control board 13.

  The amplifier circuit 521 that can amplify an audio signal generated by the audio control IC 522 or the like and output it to the speakers 8L, 8R, etc. causes distortion in the output audio signal when the power supply voltage fluctuates. May be adversely affected. Therefore, the power supply voltage VDS of DC 12 V is supplied to the amplifier circuit 521 after being stabilized by the filter circuit 131a. In the effect control board 12, after the power supply voltage VDD2 of 1 is branched into the power supply voltage VDL for driving a specific electric component and the power supply voltage VDS for supplying to the amplifier circuit 521, the filter circuit 131a is used. The stabilized power supply voltage VDS is supplied to the amplifier circuit 521. As described above, by supplying the stabilized power supply voltage VDS to the amplifier circuit 521 using the filter circuit 131a, an appropriate substrate configuration for stably operating the amplifier circuit 521 can be realized.

  In the power supply line LDS corresponding to the power supply voltage VDS to be supplied to the amplifier circuit 521, the wiring length LL2 from the filter circuit 131a to the amplifier circuit 521 is branched to the filter circuit 131a after the power supply voltage VDL is branched at the branch point DB1. It is shorter than the wiring length LL1 before input. As described above, by shortening the wiring length until the stabilized power supply voltage VDS is supplied to the amplifier circuit 521 using the filter circuit 131a, the amplifier circuit 521 is less likely to be affected by noise, and is appropriately operated. Board configuration is possible.

  In the effect control board 12, the power supply voltage VCL is branched from the power supply voltage VCC2 supplied at the terminals TA21 to TA24 of the receptacle KRE2. After the power supply voltage VCL is branched, the power supply voltage VCC is stabilized by the filter circuit 131 b. The power supply voltage VCL is, for example, a DC 5 V power supply voltage used to drive a specific electric component such as a specific motor included in the effect motor 60 or a specific LED included in the effect LED 61. The power supply voltage VCC is a DC 5 V DC power supply used to drive a predetermined electric circuit, such as the CPU 120 for effect control. As described above, the filter circuit 131 b stabilizes the power supply voltage VDD after branching the power supply voltage VCC2 of 1 into the power supply voltage VCL and the power supply voltage VDD.

  In the effect control board 12, after the power supply voltage VDD3 supplied at the terminals TA27 and TA28 of the receptacle KRE2 is stabilized by the filter circuit 131c, the power supply voltage VDC is branched so as to be able to be supplied. The power supply voltage VDC is a DC 12 V power supply voltage used to monitor the occurrence of the power supply interruption. The power supply voltage VDD3 is input to the step-down converter circuit 132 after being stabilized by the filter circuit 131c. The step-down converter circuit 132 is a circuit that converts a 1-input 2-output DC voltage.

Output. An output portion of the step-down converter circuit 132 is connected to a power supply line L10 supplying a power supply voltage of 1.05 V DC and a power supply line L33 supplying a power supply voltage of 3.3 V DC. The power supply voltage of 1.05 V DC is used to drive a predetermined electric circuit such as a graphics processor included in the display control unit 123, for example. The power supply voltage of 3.3 V DC is used to drive a predetermined electric circuit such as an image data memory included in the ROM 121 or the display control unit 123, for example. The power supply voltage of DC 3.3 V is also input to the regulator circuit 133. The regulator circuit 133 may be a linear type stabilized power supply circuit such as a series regulator such as an LDO (Low Drop-Out) regulator, for example. A power supply voltage of 3.3 V DC is input, and a power supply voltage of 1.5 V DC Convert to and output.

  The noise prevention circuit 135a shown in FIG. 15A is configured using a capacitor C20 and a resistor R20 connected in series, a capacitor C21 and a resistor R21 connected in series, and a capacitor C22 and a resistor R22 connected in series. It should just be. These configurations may be connected to the power supply line LDL supplying the power supply voltage VDL and the ground terminal (ground line) providing the ground voltage. The capacitors C20, C21 and C22 may all be bypass capacitors of 0.1 μF. The resistors R20, R21 and R22 may be any ones having a resistance value of 22Ω.

  The noise prevention circuit 135b illustrated in FIG. 15B may be configured using the capacitor C23 and the resistor R23 connected in series, and the capacitor C24 and the resistor R24 connected in series. These configurations may be connected to the power supply line LCL supplying the power supply voltage VCL and the ground terminal (ground line) providing the ground voltage. Both capacitors C23 and C24 may be bypass capacitors of 0.1 μF. Each of the resistors R23 and R24 may have a resistance value of 22Ω.

  The noise prevention circuit 135c shown in FIG. 15C may be configured using capacitors C25 to C28. The capacitor C25 may be connected to the power supply line LCC supplying the power supply voltage VCC and the ground terminal (ground line) providing the ground voltage. Capacitors C26, C27 and C28 may be connected to power supply line L33 supplying a power supply voltage of 3.3 V DC and to a ground terminal (ground line) providing a ground voltage. Each of the capacitors C25 to C28 may be a bypass capacitor of 0.1 μF.

  In the noise prevention circuit 135a shown in FIG. 15A, resistors R20, R21 and R22 are used in addition to the capacitors C20, C21 and C22. In the noise prevention circuit 135b shown in FIG. 15B, resistors R23 and R24 are used in addition to the capacitors C23 and C24. On the other hand, in the noise prevention circuit 135c shown in FIG. 15C, the capacitors C25 to C28 are used, and no resistor is used. As described above, in the noise prevention circuits 135a and 135b, the resistors R20, R21 and R22, and the resistors R23 and R24 are used as circuit elements different from the noise prevention circuit 135c.

  The power supply voltage VDL stabilized by the noise prevention circuit 135a shown in FIG. 15A is used to drive a specific electrical component such as a specific LED included in the effect LED 61, for example. The power supply line LDL supplies a power supply voltage VDL for driving a specific electrical component, such as a specific LED included in the effect LED 61, for example. The power supply voltage VCL stabilized by the noise prevention circuit 135b shown in FIG. 15B drives, for example, a specific electric component such as a specific motor included in the effect motor 60 or a specific LED included in the effect LED 61. Used to The power supply line LCL supplies a power supply voltage VCL for driving a specific electric component such as a specific motor included in the effect motor 60 or a specific LED included in the effect LED 61, for example. The power supply voltage VCC stabilized by the noise prevention circuit 135c shown in FIG. 15C and the power supply voltage of DC 3.3 V are specified, for example, an image data memory included in the effect control CPU 120, the ROM 121, or the display control unit 123. Is used to drive an electric circuit including the control circuit of The power supply line LCC supplies a power supply voltage VCC for driving an electric circuit including a specific control circuit, such as the CPU 120 for effect control. The power supply line L33 supplies a power supply voltage of 3.3 V DC for driving an electric circuit including a specific control circuit, such as the ROM 121 or an image data memory of the display control unit 123. Thus, in the noise prevention circuits 135a and 135b corresponding to the power supply voltage for driving a specific electric component such as a motor or an LED, the noise prevention corresponding to the power supply voltage for driving a specific electric circuit such as a CPU or a ROM As circuit elements different from the circuit 135c, resistors R20, R21, R22 and resistors R23, R24 are used.

  In a load circuit using a specific motor included in the effect motor 60 or a current drive circuit element such as a specific LED included in the effect LED 61, an excessive rush current is generated due to a transient phenomenon of the load circuit. , There is a risk of damage to electrical components. Therefore, in the noise prevention circuit 135a, the resistor R20 is connected in series to the capacitor C20, the resistor R21 is connected in series to the capacitor C21, and the resistor R22 is connected in series to the capacitor C22. Further, in the noise prevention circuit 135b, the resistor R23 is connected in series to the capacitor C23, and the resistor R24 is connected in series to the capacitor C24. When the power supply voltage VDL is stable, the capacitors C20, C21, and C22 are in a charging state, and the resistors R20, R21, and R22 are in a non-conducting state, so that the occurrence of power loss can be prevented. When the power supply voltage VCL is stable, the capacitors C23 and C24 are in the charging state, and the resistors R23 and R24 are in the non-conducting state, so that the occurrence of power loss can be prevented. On the other hand, in semiconductor integrated circuits such as the effect control CPU 120 and the ROM 121 or the image data memory of the display control unit 123, voltage driven circuit elements such as CMOS circuits are used, and the input impedance becomes relatively large. Therefore, inrush current due to the transient phenomenon of the circuit is hard to occur. Therefore, in the noise prevention circuit 135c, while using the capacitors C25 to C28, it is not necessary to use a resistor. In this way, by configuring the noise prevention circuit using different circuit elements according to the characteristics of the circuit and the electric component to which the power supply voltage is to be supplied, the increase of the substrate volume and the increase of the manufacturing cost can be prevented. An appropriate substrate configuration to prevent the occurrence is made possible.

  FIG. 16 shows a power supply monitoring circuit 140 using the power supply voltage VDC. In the effect control board 12, the power supply voltage VDC is used to monitor the occurrence of the power-off. The power supply monitoring circuit 140 is a circuit that is configured using, for example, a power failure monitoring and resetting module IC, and implements a power supply monitoring unit capable of outputting a power supply disconnection signal. For example, when the power supply voltage VDC exceeds a predetermined value (for example, 10 V), the power supply monitoring circuit 140 outputs a power off signal in the off state (high level). On the other hand, when the period when the power supply voltage VDC has become lower than or equal to the predetermined value continues for a predetermined standby time or more, a power off signal of the on state (low level) is output. The power-off signal output from the power supply monitoring circuit 140 is transmitted to the CPU 120 for effect control.

  The power supply voltage VDC to be monitored for outputting the power supply disconnection signal is used to generate a power supply voltage of 1.05 V DC, a power voltage of 3.3 V DC, and a power voltage of 1.5 V DC. The power supply voltage of 1.05 V DC is used to drive a predetermined electric circuit such as a graphics processor included in the display control unit 123, for example. The power supply voltage of 3.3 V DC is used to drive a predetermined electric circuit such as an image data memory included in the ROM 121 or the display control unit 123, for example. A power supply voltage of 1.5 V DC is used to drive a predetermined electric circuit such as, for example, the RAM 122. By monitoring the power supply voltage VDC used to generate the power supply voltage supplied to such an electric circuit, a power-off signal is output (turned on) before the operation state of the electric circuit becomes unstable. As a result, malfunction in various electric circuits can be prevented.

  In the effect control board 12, the power supply voltage VDD3 supplied from the terminals TA27 and TA28 of the receptacle KRE2 is stabilized by the filter circuit 131c and then input to the step-down converter circuit 132. The step-down converter circuit 132 uses the input voltage to generate a power supply voltage of 1.05 V DC and a power supply voltage of 3.3 V DC higher than 1.05 V DC. The power supply voltage of DC 3.3 V is input to the regulator circuit 133. The regulator circuit 133 uses an input voltage to generate a power supply voltage of 1.5 V DC. The power supply voltage of 1.5 V DC is a power supply voltage higher than 1.05 V DC but lower than 3.3 V DC. Thus, using the step-down converter circuit 132 and the regulator circuit 133, the power supply voltage of 1.05 V DC, the power supply voltage of 1.5 V DC higher than 1.05 V DC, and the DC 3 higher than 1.5 V DC While the step-down converter circuit 132 outputs a power supply voltage of 1.05 V DC and a power supply voltage of 3.3 V DC, the regulator circuit 133 can generate a power supply voltage of 3 V. Output 5V power supply voltage.

  After the power supply voltage VDD3 is stabilized by the filter circuit 131c, the branched power supply voltage VDC of 12 V DC is supplied to the power supply monitoring circuit 140 that monitors the occurrence of the power-off. Therefore, the input voltage of step-down converter circuit 132 is common to power supply voltage VDC of 12 V DC, and the input voltage of step-down converter circuit 132 is to be monitored by power supply monitoring circuit 140. Note that after the power supply voltage VDC is branched, a bypass capacitor of a predetermined capacity (for example, 47 μF) may be connected to the input side of the step-down converter circuit 132.

  Among the power supply voltages generated using the step-down converter circuit 132 and the regulator circuit 133, the power supply voltage of 1.05 V DC, which is a low voltage with the smallest voltage value, is Supplied to a microprocessor. The power supply voltage of 1.05 V DC is not limited to that supplied to the graphics processor of the display control unit 123, and may be supplied to, for example, any microprocessor for effect control CPU 120 and the like.

  Of the power supply voltages generated using the step-down converter circuit 132 and the regulator circuit 133, the power supply voltage of 3.3 V DC, which is the largest voltage with the largest voltage value, is used, for example, in the image data memory of the ROM 121 and the display control unit 123. Supplied. The ROM 121 only needs to be able to start up earlier than the electric component driven by the power supply voltage of 1.5 V DC.

  Among the power supply voltages generated using the step-down converter circuit 132 and the regulator circuit 133, a power supply voltage of 1.5 V DC higher than 1.05 V DC and lower than 3.3 V DC is supplied to, for example, the RAM 122. The RAM 122 is, for example, a temporary storage memory that can store and read data in a double data rate (DDR) mode, and functions as a memory module such as a single in-line memory module (SIMM) or a dual in-line memory module (DIMM). Configure the substrate. Such a substrate constituting the RAM 122 may be configured as a separate substrate that can be detachably connected to the effect control substrate 12. In this case, the power supply voltage of 1.5 V DC is supplied to a substrate different from the effect control substrate 12.

  When a one-input three-output step-down converter circuit is used instead of the step-down converter circuit 132 and the regulator circuit 133, a special dedicated circuit is required, which may increase the manufacturing cost. In addition, the amount of heat generation in a single circuit may be increased to damage the electric circuit. Therefore, in the step-down converter circuit 132, the power supply voltage VDD3 stabilized by the filter circuit 131c (the same applies to the power supply voltage VDC) is input to output a power supply voltage of 1.05 V DC and a power voltage of 3.3 V DC. . The regulator circuit 133 receives a power supply voltage of 3.3 V DC and outputs a power supply voltage of 1.5 V DC. This makes it possible to prevent the increase of the manufacturing cost and to make the appropriate substrate configuration to disperse the heat generation in the electric circuit.

  The power supply voltage VDC that is the same as or substantially the same as the voltage supplied to the step-down converter circuit 132 is supplied to the power supply monitoring circuit 140, and the occurrence of a power-off is monitored. Thus, since the power supply voltage VDC used for generation of various power supply voltages by the step-down converter circuit 132 and the regulator circuit 133 is to be monitored by the power supply monitoring circuit 140, a pachinko gaming machine 1 such as a graphics processor such as Before the operation state of the electrical circuit, which is important for performing the rendering, becomes unstable, an appropriate substrate configuration for detecting the occurrence of the power-off becomes possible.

  The power supply voltage of DC 1.05 V output from the step-down converter circuit 132 is supplied to a specific microprocessor, such as a graphics processor of the display control unit 123, for example. By outputting the power supply voltage of 1.05 V DC from the step-down converter circuit 132, the power supply voltage of 1.05 V DC is output until a longer time elapses than in the configuration output from the regulator circuit 133 when a power failure occurs. Can be maintained. As a result, when a power failure occurs, an appropriate board configuration, such as the graphics processor of the display control unit 123, continues the operation of the electrical circuits that are important for executing effects in the pachinko gaming machine 1 as much as possible. It will be possible.

  The power supply voltage of 3.3 V DC output from the step-down converter circuit 132 is supplied to, for example, the ROM 121, and starts earlier than an electric component such as the RAM 122 driven by the 1.5 V DC power supply voltage output from the regulator circuit 133. It becomes possible.
