That is, as shown in FIG. 25, the via v204 is connected to the resistor built-in transistor T1 by a wiring path cp527 provided in the sixth wiring layer L6, further connected to the logic integrated circuit IC7 by a wiring path cp528, and further connected to the logic integrated circuit IC7 by a wiring path cp529. , is connected to the WDT built-in reset integrated circuit (reset IC) IC10 via a via v203 forming the test point TP23. The wiring path cp528 is connected to DC 3.3V (fifth wiring layer L5) through a resistor R19, the wiring path cp529 is connected to the ground (second wiring layer L2) through a capacitor C40, and the resistor R26 is connected. are connected to DC 3.3V (fifth wiring layer L5) via the Via.

The reset circuit on the sixth wiring layer L6 side is constructed as shown in FIG. A system reset signal can be input to the logic integrated circuit IC7 via the liquid crystal control first connector CN31, and a reset signal can be input from the WDT built-in reset integrated circuit (reset IC) IC10. When a signal is input, a reset signal is transmitted to the composite chip 104 and the control ROM 105 via the resistor built-in transistor T1 for noise countermeasures. For example, a data output terminal ASIBLDTB for LED of the composite chip 104 is connected to the WDT built-in reset integrated circuit (reset IC) IC10 for resetting the WDT.

Here, the test point TP23 is for checking when the reset integrated circuit IC10 operates, and as shown in FIG. Therefore, the identification information "TP23" indicating the test point TP23 is displayed by silk printing on the sixth wiring layer L6 side where the wiring path cp421 is provided, that is, on the back surface 98b side. is normal. On the other hand, the check operation by the test point TP23 must be performed with the board assembled (see FIGS. 8 and 9) or with the board assembled (installed) in the game machine main body. The rear surface 98b of 98 cannot be touched by a tester because it is shaded by the presentation interface board 96 and the liquid crystal interface board 97 facing each other. Therefore, in this embodiment, as shown in FIG. 43, the display of "TP23", which is the identification information indicating the test point TP23, is displayed on the wiring path cp421 side where the test point TP23 is arranged, that is, not on the back surface 98b side but on the front surface. It is arranged on the 98a side. Since the test point TP23 is configured by the via v203 penetrating the substrate body 190, it is possible to apply the tester from the surface 98a side of the substrate body 190 as well.

The test point TP17 is provided in the via v204 that connects the wiring path cp418 on the first wiring layer L1 side and the wiring path cp419 on the sixth wiring layer L6 side. The display of "TP17" is also arranged on the surface 98a side like the test point TP23.

The same applies to the other test points TP28 and TP33 described above. That is, the test point TP28 is provided on the wiring path cp3 of the third wiring layer L3, but the display of "TP28", which is the identification information indicating the test point TP28, is arranged on the surface 98a side. Also, the test point TP33 is provided on the wiring path cp505 of the sixth wiring layer L6, but the display of "TP33", which is the identification information indicating this test point TP33, is arranged on the surface 98a side.

Next, wiring paths P46 and P47 connected to the 8/16-bit mode selection terminal BYTE#, writable input terminal WE#, and write inhibit/program input terminal WP#/ACC of the control ROM 105 will be described. These wiring paths P46 and P47 are not connected to the composite chip 104. FIG.

In the wiring path P46 (FIG. 40), as shown in FIG. 27, the terminal connection portion BYTE# provided in the control ROM arrangement region 192 of the first wiring layer L1 is connected to the via v48 by the wiring path cp531. The via v48 is arranged in the vicinity of the terminal connection portion BYTE# on the outside (-X side) of the control ROM arrangement area 192, and as shown in FIG. It is connected. Thus, in this embodiment, the 16-bit communication mode is selected by connecting the 8/16-bit mode selection terminal BYTE# of the control ROM 105 to the power supply (H level).

In the wiring path P47 (FIG. 40), as shown in FIG. 27, the terminal connection portion WE# (first predetermined terminal) provided in the control ROM arrangement region 192 of the first wiring layer L1 is connected to the via v111 by the wiring path cp541. is connected with This via v111 (first predetermined inter-layer conductive portion) is arranged near the terminal connection portion WE# on the outside (+X side) of the control ROM arrangement area 192, and as shown in FIG. is connected to DC 3.3V through As described above, in this embodiment, the writable input terminal WE# of the control ROM 105 is connected to the power supply (H level), so that when it is at H level (when not reading), it is in the output disabled mode, and when it is at L level (when it is reading). ), the mode can be switched according to the value (H/L) of the output enable input terminal OE#. Output enable input terminal OE# is connected to read strobe output terminal HRD of composite chip 104 as described above.

In the wiring path P47, as shown in FIG. 27, the terminal connection portion WP#/ACC (second predetermined terminal) provided in the control ROM arrangement area 192 of the first wiring layer L1 is connected to the via v112 by the wiring path cp542. It is connected. The via v112 is arranged near the terminal connection portion WP#/ACC outside the control ROM arrangement area 192 (on the +X side). As shown in FIG. 25, the via v112 (second predetermined inter-layer conductive portion) is connected to the via v111 through a resistor R43 by a wiring path cp543 provided in the sixth wiring layer L6. This via v111 is connected to DC 3.3V through the fifth wiring layer L5 as described above. As described above, in the present embodiment, the write inhibit/program input terminal WP#/ACC of the control ROM (specific electronic component) 105 is connected to the power supply (H level), so that it is set to be writable and program executable. ing. Also, by connecting to the power supply through a resistor R43, an input exceeding the H level is eliminated and the H level is stably set.

For example, depending on the type of control ROM, when there is an input exceeding H level, if a mode setting different from write prohibition/permission and program execution prohibition/permission is performed, the Even if the input exceeds the H level due to noise, etc., the control ROM is set to a mode different from prohibition/permission of writing and prohibition/permission of program execution by configuring the control ROM so that it is stably at the H level. It is possible to prevent this from happening.

To summarize the configuration of the wiring paths P1 to P47 described above, among the wiring paths P2 to P45 connecting the composite chip 104 and the control ROM 105, the wiring paths P2 to P43 and P45 (specific wiring paths) are shown in FIG. , as shown in FIGS. 35 to 40, vias v60 to v108 (specific inter-layer conductive portions; vias indicated in gray in FIGS. 35 to 40) arranged in the control ROM arrangement area (second arrangement area) 192 are Further, wiring paths P2 to P16, P19 to P23, P35 to P43, and P45 (first specific wiring paths) among them are connected to terminal connections on the control ROM 105 side. The parts A0 to A14, A17 to A21, Q8 to Q15, CE# and RESET# are connected from the inside of the control ROM arrangement area 192 (wiring lines indicated by thick lines in FIGS. 35 to 40). Thus, the wiring path connecting the composite chip 104 and the control ROM 105 is arranged so as to pass through the control ROM arrangement area 192 which has a relatively large space, and the terminals of the control ROM 105 are connected as much as possible. By connecting from the inside of the control ROM arrangement area 192, the wiring patterns on the substrate can be arranged more efficiently, and the limited space can be used more effectively.

Wiring connecting vias v60 to v108 (specific inter-layer conductive portions) arranged in the control ROM arrangement area (second arrangement area) 192 to terminal connection parts on the control ROM 105 side from outside the control ROM arrangement area 192 As shown in FIG. It is arranged so as to cross sides 192a and 192b on the outside of each terminal connection portion. By configuring in this way, the wiring length can be shortened compared to the case of wiring avoiding the control ROM arrangement area 192, so that the wiring efficiency can be improved and noise can be reduced. In addition, since the control ROM 105 is actually located in the range indicated by the control ROM arrangement area 192, the wiring pattern cannot be visually observed, and therefore unauthorized access to the wiring pattern can be prevented. It is possible.

Also, a wiring path, more specifically, a wiring path cp233, is connected in the first wiring layer L1 to the vias v60 to v108 (specific inter-layer conductive portions) arranged in the control ROM placement area (second placement area) 192. , cp243 and cp253 are also arranged so as to cross the long side 192a of the control ROM arrangement area 192 outside the respective terminal connection portions, as shown in FIG. By adopting such a configuration at a plurality of locations together with the configuration in the preceding paragraph, the effect described in the preceding paragraph becomes more effective.

A ROM socket 193 (FIG. 8) is fixed to the control ROM arrangement area 192, and the bottom wall (shielding wall corresponding to the specific inter-layer conduction part) 193a of the ROM socket 193 shields the control ROM arrangement area 192. Even when the control ROM 105 is removed from the ROM socket 193, the wiring pattern in the control ROM arrangement area 192 including the vias v60 to v108 (specific inter-layer conduction portions) cannot be visually recognized from the outside and cannot be accessed.

The vias v60 to v108 (specific inter-layer conductive portions) in the control ROM arrangement area 192 penetrate from the front surface (first surface) 98a to the rear surface (second surface) 98b of the substrate body 190, thereby enhancing the heat radiation effect. The vias v60 to v108 (specific inter-layer conductive portions) in the control ROM arrangement area 192 are connected to predetermined electronic components such as ICs, resistors, capacitors, connectors, etc. on the back surface 98b side, that is, on the sixth wiring layer L6 side. .

As for the wiring paths P2 to P45 connecting the composite chip 104 and the control ROM 105, the first wiring portion connecting the composite chip 104 and a predetermined via (predetermined inter-layer conductive portion) is connected to the predetermined via and the control ROM 105. and a third wiring portion for connecting predetermined vias to other electronic components such as the liquid crystal control first connector CN31. The second wiring portion is formed in a first predetermined wiring layer such as the first wiring layer L1, and the third wiring portion is formed in a second predetermined wiring layer L3 and sixth wiring layer L6 which are different from the first predetermined wiring layer. They are arranged in wiring layers, respectively.

Among the wiring paths P2 to P45, for the wiring paths P2 to P42 for transmitting address/data information, predetermined vias (predetermined inter-layer conductive portions) serving as branch points are located in the control ROM layout area (second layout area). ) 192 (vias indicated in gray in FIGS. 35 to 40), the second wiring portion is on the first wiring layer L1, and at least a part of the first wiring portion are provided in the fourth wiring layer L4 (an example of a predetermined wiring layer different from the first wiring layer), and the third wiring portion is provided in the first wiring layer L1 (first predetermined wiring layer). This makes it possible to improve the preventiveness against fraudulent acts such as unauthorized modification of wiring patterns and vias for transmitting address/data information. By drawing wiring patterns in the control ROM arrangement area 192, wiring space can be secured in other areas. In addition, particularly at branch points, wiring patterns tend to be densely packed over multiple layers of the substrate, so a sufficient wiring space is required at the branch point. It is effective to place the branch point in the control ROM placement area 192 with the .

In addition, among the vias v60 to v107 (specific inter-layer conductive portions) in the control ROM arrangement area 192, the vias v61 to v85 and v103 forming part of the wiring paths P2 to P26 (address wiring) for transmitting address information. ∼ v107 (first specific interlayer conduction portion) and vias v87 to v102 (second specific interlayer conduction portion) forming part of wiring paths P27 to P42 (data wiring) for transmitting data information are controlled. They are arranged in the Y direction (first direction), which is the arrangement direction of the terminals in the ROM 105 .

Address output terminals HAD1 to HAD25 and data input/output terminals HDT0 to HDT15 (first terminal) on the composite chip 104 side, and corresponding address input terminals A0 to A24 and data input/output terminals Q0 to Q15 on the control ROM 105 side. The wiring paths P2 to P42 connecting them have vias v60 to v85 and v87 to v107 (specific inter-layer conductive portions) in the control ROM arrangement area 192, The arrangement of vias v60 to v85 and v87 to v107 (specific inter-layer conduction portions) in the control ROM arrangement area 192 is approximated to the arrangement of corresponding terminals (specific second terminals) on the control ROM 105 side. As a result, it is possible to arrange the wiring patterns that connect the specific interlayer conductive portions and the terminals of the control ROM, and for example, there is no need to arrange the patterns so that the positional relationship between a plurality of wiring patterns changes (twists). Therefore, the connection method is easier, and the space in the control ROM arrangement area 192 can be used more effectively. In this way, when the terminal arrangement of the composite chip 104 and the terminal arrangement of the control ROM 105 are different, a wiring pattern with a relatively short wiring distance from the specific inter-layer conductive portion in the arrangement area of the control ROM 105 to the terminals of the control ROM 105 can be used. Rather than devising the routing of the specific interlayer conductive portion, by devising the routing of a wiring pattern having a relatively long wiring distance from the composite chip 104 to the specific interlayer conductive portion, the arrangement of the specific interlayer conductive portion is approximated to the terminal arrangement of the control ROM 105. is more effective in terms of wiring efficiency.

Specifically, as shown in FIG. 27, for example, address input terminals A0 to A6 and corresponding vias v85 to v79, address input terminals A17 to A20 and corresponding vias v68 to v64, and data input/output terminals Q12 to Q15. and vias v90 to v87 corresponding thereto are arranged in substantially the same order in the Y direction. , Data input/output terminals Q0 to Q3 and corresponding vias v102 to v99, data input/output terminals Q8 to Q11 and corresponding vias v94 to v91, data input/output terminals Q4 to Q7 and corresponding vias v98 to v95 are arranged in substantially reversed order in the Y direction. In this way, rather than considering only the terminal arrangement of the control ROM 105 and devising the arrangement of the specific interlayer conductive portions, the terminal arrangement on the side of the composite chip 104 and the terminal arrangement on the liquid crystal control first connector CN31 side, which are also connected in the same manner, are not devised. Considering the above, the specific inter-layer conductive portions may be arranged. Although this partly complicates the connection relationship with the control ROM 105, the connection between the composite chip 104 and the liquid crystal control first connector CN31 side located farther than the terminals of the control ROM 105 is based on the specified inter-layer conduction portion. Since the connection relationship with the terminals is simplified, it is possible to improve the wiring efficiency of the entire board. That is, in the control ROM arrangement area 192, the wiring efficiency of the entire substrate can be improved by devising the arrangement of the specific inter-layer conductive portions as necessary. Also, the wiring efficiency of the entire substrate can be improved not only within the control ROM placement area 192, but also by devising the arrangement of vias serving as branch points as described above.

Address output terminals HAD1 to HAD25 and data input/output terminals HDT0 to HDT15 (first terminals) on the composite chip 104 side correspond to address input terminals A0 to A24 and data input/output terminals Q0 to Q15 on the control ROM 105 side. (second terminal), but also the terminals had1 to had25 and hdt0 to hdt15 (third terminal) of the liquid crystal control first connector CN31 are arranged differently. ) are made to match (approximately) the arrangement of the terminals had1 to had25 and hdt0 to hdt15 (third terminals) of the liquid crystal control first connector CN31. That is, as shown in FIGS. 28, 29 and 33, the vias v61 to v85 and v87 to v102 (specific inter-layer conductive portions) are arranged in the Y direction so that the corresponding terminals had1 to Since it matches the arrangement of had25 and hdt0 to hdt15 in the X direction, the wiring path group (third wiring path group) connecting them can be arranged in parallel without twisting. As a result, a wiring path group ( The second wiring path group) has a complicated wiring pattern including twists, but this can be easily realized by arranging it in the control ROM arrangement area 192 which has a relatively large space.

Among wiring paths P2 to P42 for transmitting address/data information, wiring paths P2 to P13 and P19 to P42 are vias v61 to v68, v74 to v85, and v87 to v102 ( The wiring paths P14 to P18 are branched to the control ROM 105 side and the liquid crystal control first connector CN31 side at the specific inter-layer conduction portion). Vias v103 to v107 are separately provided in the control ROM arrangement area 192 on the wiring path connecting the vias v69 to v73 and the liquid crystal control first connector CN31 without branching, and the vias v103 to v107 branch to the control ROM 105 side. ing. With this configuration, the wiring to the liquid crystal control first connector CN31 is arranged in parallel without being twisted in harmony with other wiring paths, and the wiring to the control ROM 105 is also prevented from interfering with other wiring paths. It is possible to efficiently arrange while avoiding.

Further, specific one end terminals A0 to A7, A17, A18, A20, A21, Q0 to Q3, Q8 to Q11 included in one end terminals arranged on one end side of the control ROM (second electronic component) 105 and The corresponding first specific terminals HAD0 to HAD7, HAD17, HAD18, HAD20, HAD21, HDT0 to HDT3, HDT8 to HDT11 on the side of the corresponding composite chip (first electronic component) 104 are connected to vias v65 to v68, v78 to v85, v91 to v94. , v99 to v102 (first interlayer conductive portions), a plurality of one end side wiring paths P2 to P9, P19, P20, P22, P23, P27 to P30, P35 to P38, a control ROM (second electronic Specific other-end terminals A8-A16, A19, A22-A24, Q4-Q7, Q12-Q15 included in the other-end terminals arranged on the other-end side of component) 105 and their corresponding composite chips (first The second specific terminals HAD8 to HAD16, HAD19, HAD22 to HAD24, HDT4 to HDT7, HDT12 to HDT15 on the electronic component) 104 side are connected to vias v61 to v63, v66, v74 to v77, v87 to v90, v95 to v98 (second a plurality of other end side wiring paths P10 to P18, P21, P24 to P26, P31 to P34, P39 to P42, which are connected to each other via a first interlayer conduction portion and a second interlayer conduction portion; are arranged close to each other so as to have different arrangements from those of the first specific terminal and second specific terminal and correspond to the specific one-end terminal and the specific other-end terminal, respectively.

In addition, internal connection wiring portions connected from the inside of the control ROM arrangement area 192 and external connection wiring portions connected from the outside are alternately arranged with respect to the plurality of ROM terminal connection portions arranged in a row. That is, as shown in FIG. 27, for the terminal connection portions Q0, Q8, Q1, Q9, Q2, Q10, Q3, and Q11 of the control ROM arrangement area 192, the external connection wiring portions cp303, cp313, cp323, cp333 and the internal wiring portions are connected. The connection wiring portions cp383, cp393, cp403, and cp413 are alternately connected. Moreover, the vias v102 to v99 on the other end side of the external connection wiring portions cp303, cp313, cp323, and cp333 are arranged close to each other, and the vias v94 to v91 on the other end side of the internal connection wiring portions cp383, cp393, cp403, and cp413. are also arranged close to each other. Similarly, the terminal connection portions Q15/A-1, Q7, Q14, Q6, Q13, Q5, Q12, and Q4 of the control ROM arrangement area 192 are connected to the internal connection wiring portions cp453, cp443, cp433, and cp423. The wiring portions cp373, cp363, cp353 and cp343 are alternately connected. Moreover, the vias v87 to v90 on the other end side of the internal connection wiring portions cp453, cp443, cp433, and cp423 are arranged close to each other, and the vias v95 to v98 on the other end side of the external connection wiring portions cp373, cp363, cp353, and cp343. are also arranged close to each other. In this way, by arranging and grouping the internal connection wiring section and the external connection wiring section in close proximity instead of the terminal arrangement of the control ROM 105, the routing of the wiring pattern can be simplified and the wiring efficiency can be improved. .

The first wiring paths P2 to P42 for transmitting address information or data information and the second wiring path P43 for transmitting chip select information are in different wiring layers. The layer L4 and the second wiring path P43 are connected to the vias v61 to v85, v87 to v101 and v60 (specific inter-layer conductive portions) in the control ROM arrangement area 192 from the composite chip 104 side in the sixth wiring layer L6. In this way, by wiring the chip select signal, which is important in data transmission, using a wiring layer different from the wiring pattern for transmitting address information or data information, transmission of the wiring pattern for transmitting address information or data information can be achieved. It is possible to make it difficult for noise to get on the chip select signal, and it is possible to have a configuration that is resistant to noise. Further, by making the pattern of the wiring path for the chip select signal different from that of other wiring paths, it becomes relatively easy to specify the wiring of the chip select signal, and it is possible to check whether the wiring pattern is short-circuited. It is possible to relatively easily perform checks and energization checks.

Further, in the wiring path P45 constituting the reset circuit, the wiring paths cp418 to cp421 (reset first wiring paths) connecting the reset integrated circuit (reset IC) IC10 and the via v174 (predetermined interlayer conduction portion), and the via v174 Wiring paths cp413 to cp415 (reset second wiring path) connecting (predetermined interlayer conductive portion) and reset terminal HRESET of composite chip 104, via v174 (predetermined interlayer conductive portion) and reset terminal RESET# of control ROM 105 are connected. Wiring paths cp416 and cp417 (third reset wiring path) are provided for connection, and a test point TP17 (first reset wiring path) penetrating through the liquid crystal control board 98 in the board thickness direction is provided on the wiring paths cp418 to cp421 (first reset wiring path). test point) and test point TP23 (second test point), identification information "TP17" and "TP23" indicating these test points TP17 and TP23, liquid crystal control board 98 to another effect interface board 96, liquid crystal interface It is shown on the surface (first surface) 98a opposite to the substrates 96 and 97 when assembled together with the substrate 97 and the like. The reset integrated circuit (reset IC) IC10 is arranged on the rear surface (second surface) 98b side. As a result, when the board is assembled (see FIGS. 8 and 9) or when the board is assembled (installed) in the game machine main body, the part of the wiring path where the test points TP17 and TP23 are arranged cannot be visually recognized. In spite of this, it is possible to easily perform checking work using the test points TP17 and TP23 based on the identification information displayed on the visible surface 98a side.

Wiring paths cp418 to cp421 (reset first wiring path) are arranged on the front surface (first surface) 98a side and wiring path cp418 (first wiring path) on the back surface (second surface) 98b side. Wiring paths cp420 and cp421 (second wiring paths) and a via v204 (reset first interlayer conduction portion) connecting them are provided, and a test point TP17 (first test point) is arranged in the via v204 to perform a test. A point TP23 (second test point) is placed on the wiring path cp421 (second wiring path).

Further, the control ROM (specific electronic component) 105 operates in an operation mode according to the voltage level of the write inhibit/program input terminal WP#/ACC (second predetermined terminal), and the writable input terminal WE# (first A predetermined terminal) is connected to the power supply wiring path of the fifth wiring layer L5 via a via v111 (first predetermined interlayer conductive portion), and a write inhibit/program input terminal WP#/ACC (second predetermined terminal) is connected to a resistor It is connected to via v111 (first predetermined inter-layer conductive portion) through R43. A control ROM (specific electronic component) 105 is arranged on the surface (first surface) 98a of the liquid crystal control board 98, and a resistor R43 is arranged on the rear surface (second surface) 98b. A write inhibit/program input terminal WP#/ACC (second predetermined terminal) and a resistor R43 are connected via the . Thus, the via for connecting WP#/ACC (second predetermined terminal) to the power supply wiring path via resistor R43 is commonly used as the via for connecting WE# (first predetermined terminal) to the power supply wiring path. , the number of vias can be reduced compared to connecting via individual vias.

A plurality of terminals are arranged in a matrix on the bottom side of the composite chip 104. Out of the plurality of terminals, the outer terminals arranged near the outer circumference of the composite chip arrangement area (first arrangement area) 191, For example, the terminals HDT0, HDT1, HDT4, HDT5, etc. arranged in the second row on the outermost peripheral side and inside thereof are connected to the control ROM 105 by first wiring paths P27, P28, P31, P32, etc., and are arranged inside the outer terminals. Arranged inner terminals such as terminals HDT2, HDT3, HDT6, etc. are connected to the control ROM 105 by second wiring paths P29, P30, P33, etc., and first wiring paths P27, P28, P31, P32, etc. are connected to the composite chip layout area. Vias v32, v31, v37, v46, etc. (first interlayer conductive portions) arranged outside 191 and external terminals HDT0, HDT1, HDT4, HDT5, etc. are connected in a first wiring layer L1, and a second wiring path P29 is connected. , P30, P33, etc. connect the vias v24, v8, v17, etc. (second interlayer conductive portions) arranged inside the composite chip placement region 191 and the inner terminals HDT2, HDT3, HDT6, etc., in the first wiring layer L1. is doing. Also, the distances from the inner terminals HDT2, HDT3, HDT6, etc. to the vias v24, v8, v17, etc. (second interlayer conductive portions) are set to the distances from the outer terminals HDT0, HDT1, HDT4, HDT5, etc. It is shorter than the distance to (the first interlayer conductive portion).

Thus, in the composite chip 104 having a plurality of terminals arranged in a matrix, the outer terminals arranged in the vicinity of the outer periphery of the arrangement area of the composite chip 104 are connected to the vias arranged outside the composite chip 104. Therefore, a wiring space is generated near the outer periphery of the composite chip 104, and the wiring pattern of the inner terminal of the composite chip 104 can be easily routed to the outside of the composite chip, so that the wiring efficiency can be improved. As for the wiring space described above, since a wiring space in the vicinity of the outer periphery of the composite chip is generated in a plurality of wiring layers of the substrate, even if any wiring layer among the plurality of wiring layers is used, the wiring space may extend to the outside of the composite chip. It goes without saying that it becomes easy to wire the wiring pattern.

Although the embodiments of the present invention have been described in detail above, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. For example, in the embodiment, the wiring paths P2 to P42 for transmitting address information/data information between the composite chip 104 and the control ROM 105 are connected to specific inter-layer conduction lines arranged in the control ROM arrangement area (second arrangement area) 192. However, at least some of the wiring paths P2 to P42 may not have the specific inter-layer conductive portion.

In the embodiment, the vias v61 to v85 and v87 to v102 (specific inter-layer conduction portions) in the wiring paths P2 to P42 are arranged in the Y direction so that the corresponding terminals had1 to had25 and hdt0 to the terminals of the liquid crystal control first connector CN31 The Y-direction arrangement of the vias v61 to v85 and v87 to v102 (specific inter-layer conductive portions) may be made to match (or approximate) the terminal arrangement of the control ROM105.

In the embodiment, regardless of whether the test points to be checked exist on the front or back of the board, the test points that need to be checked while the board is assembled are placed on the outer surface of the board when the board is assembled. Although configured to display test point identification information, such test point identification information may be displayed on both sides of the board.

In the embodiment, among the terminals of the composite chip 104, the terminals (outer terminals) arranged in the second row on the outermost side and the inner side of the composite chip arrangement area (first arrangement area) 191 are formed in the first wiring layer. In L1, it is connected to the inter-layer conductive portion arranged outside the composite chip placement region 191, and the terminals (inner terminals) inside thereof are arranged inside the composite chip placement region 191 in the first wiring layer L1. Although it is configured to be connected to the interlayer conductive portion, only the terminals on the outermost side in the composite chip placement area 191 may be used as outer terminals, or the terminals in the third row from the outermost side may be used as outer terminals.

Further, in the embodiment, only the wiring related to the terminal on the one edge side of the composite chip 104 was specifically illustrated, but the configuration is not limited to this, and the other edge side of the composite chip 104 has the same configuration or embodiment. may be configured to have the contents described in . Thus, by adopting the configuration described in this embodiment also on each edge side of the composite chip 104, it is possible to further increase the wiring efficiency. For example, a configuration as shown in FIG. 12 is given as an example.

In the embodiment, an example in which the first to sixth wiring layers L1 to L6 are provided on the liquid crystal control board 98 is shown, but the number of wiring layers may be less or more than this. When the number of wiring layers is reduced, the solid wiring layer for ground connection and the solid wiring layer for power supply connection may be omitted.

The connection between the terminals of the composite chip 104 and the vias in the composite chip placement area 191 may be designed such that the distances between the terminals and the vias are substantially the same. As a result, the distances between the plurality of terminals and the vias are substantially equal, so that noise is less likely to enter and the vias can be arranged in a more appropriate state.

In addition, with regard to the directions in which wirings are drawn out from the terminals of the composite chip 104 toward the vias, it is desirable that vertically and horizontally adjacent terminals have the same wiring drawing direction (via arrangement direction). Further, when these terminals are treated as one group, it is desirable that the direction of drawing out the wiring (the direction of arranging the vias) for another group of terminals is different from that described above. By setting the wiring lead-out direction (via arrangement direction) for each terminal group in this way, it becomes easy to check and recognize the information of each terminal by the wiring pattern, so that inspection and checking after completion is facilitated. Become. Further, by grouping terminals for transmitting address information into one group and terminals for transmitting data information into one group, the above-described effects can be exhibited more effectively. Further, with respect to terminals for individual signals such as chip select signals, confirmation and recognition may be facilitated by providing vias in a wiring lead-out direction different from that of the above-described one group. In addition, by providing vias in a common wiring lead-out direction for terminals for chip select signals as well, important terminals and signal lines for chip select signals are made difficult to identify, and a configuration that is strong against fraudulent acts may be provided.

As shown in FIG. 26, a wiring pattern may be provided that reaches the control ROM placement area 192 or its vicinity without vias, such as the wiring path cp221 connected to the HAD22 terminal of the composite chip 104 . By wiring in this manner, the number of vias around the composite chip 104 can be reduced, so that the corresponding space can be used as a location for installing other wirings and vias. Further, although the wiring path cp221 is connected to the via v53, it may be configured to be connected to the terminal of the control ROM 105 without via the via.

As shown in FIG. 27, wiring patterns of special terminals such as OE#, WE#, BYTE#, WP#ACC, CE#, and RESET# among the terminals of the control ROM 105 transmit address information and data information. The connection distance from the via may be set shorter than the wiring pattern. As a result, it is possible to easily distinguish the types of wiring patterns during board assembly, inspection, and the like. Conversely, by setting a long connection distance, it may be configured such that the types of wiring patterns can be easily distinguished. Also, since it is a terminal connection pattern for controlling the operation of the control ROM 105, it is desirable to use a relatively short wiring pattern in consideration of noise and the like.

As shown in FIG. 27, in the control ROM placement area 192, by displacing the first via array group (v61 to v85, etc.) and the second via array group (v87 to v102, etc.) in the X-axis direction, It is possible to make it easier to pull out wiring patterns in the Y-axis direction from each array group. If the first via array group and the second via array group are arranged in the Y-axis direction without being shifted in the X-axis direction, they will not fit in the control ROM arrangement area 192 and protrude. By arranging them so as to overlap in the Y-axis direction, the first via array group and the second via array group can be accommodated in the control ROM arrangement area 192, and the wiring space in the control ROM arrangement area 192 can be further reduced. Effective utilization is possible.

Even if the first via array group and the second via array group are shifted in the Y-axis direction and arranged so as to overlap in the X-axis direction, if they fit within the control ROM placement area 192, they are shifted in the Y-axis direction. may be arranged so as to overlap in the X-axis direction. In this case, it becomes difficult to pull out the wiring patterns in the Y-axis direction from each array group, but at least in the X-axis direction, there is no restriction. Also, for example, when the first via array group or the second via array group is the branch point, after considering the arrangement of the connection terminals at the branch destinations, they are arranged so as to be shifted in the Y-axis direction and overlapped in the X-axis direction. It may be so arranged if it results in a more efficient arrangement. Similarly, they may be arranged so as to be shifted in the X-axis direction and overlapped in the Y-axis direction. Depending on the shape of the control ROM layout area 192 and how the wiring pattern is routed, there may be a case where a more suitable layout relationship is obtained.

As shown in FIG. 20, by determining the layout relationship between the composite chip 104 and the control ROM 105 according to the position of the terminal arrangement of the composite chip 104 connected to the terminals of the control ROM 105, the physical connection distance can be reduced. It may be configured to be closer. This is not limited to the control ROM 105 in particular, but is based on the position of each terminal of the composite chip 104. By determining the arrangement position, the arrangement direction, the distance, etc. of the electronic parts connected to these terminals, the wiring efficiency is increased. be able to. Of course, only specific electronic components, such as the control ROM 105, may be placed in the above-described arrangement relationship, thereby partially improving the wiring efficiency. By doing so, the wiring efficiency of the entire substrate can be improved.

In addition, regarding wiring that needs to connect composite chip 104 and a plurality of electronic components, such as a wiring pattern for transmitting address information and data information, a first electronic component (eg, control wiring) that is close to composite chip 104 (ROM 105) and a second electronic component farther away (e.g. liquid crystal control first connector CN31). may be increased. Further, it goes without saying that wiring efficiency can be further improved by providing both the first electronic component and the farther second electronic component on the side where the connection terminals of the composite chip are located. Moreover, wiring efficiency may be improved by providing the far second electronic component of the first electronic component and the second electronic component on the side where the connection terminal of the composite chip 104 is located. In this case, the first electronic component is placed on a side different from the side on which the connection terminals of the composite chip are located. Considering the wiring efficiency of the pattern, it may be more effective. Also, the first electronic component is not limited to the control ROM, and may be a connector, (terminating) resistor, or the like. Similarly, the second electronic component is not limited to a connector, and may be a control ROM or (terminating) resistor.

As shown in FIG. 19, the terminals of the control ROM 105 include terminals (NC terminals, etc.) that are not connected to the terminals of the composite chip 104. In FIG. A via for connecting a wiring pattern connected to a terminal other than the NC terminal is provided in a location (region) shifted in the X-axis direction from the location where the NC terminal of the control ROM 105 is located in the ROM arrangement region 192 (see FIG. 27). corresponds to v80 to v85) may be provided. The reason for this configuration is that there is no need to consider the wiring patterns and via layouts connected to the NC terminals, etc., so there is a tendency for wiring spaces to occur relatively easily around them, so that area is utilized. This is because vias can be placed by In addition, since there is enough space around the NC terminals and the like, there is an advantage that the wiring pattern can be easily pulled out from the via in the Y-axis direction or the X-axis direction. Moreover, the above effects can be obtained by applying the same configuration not only to the NC terminal but also to the VCC terminal and the GND terminal.

As shown in FIG. 31, vias (eg v49 to v54) for connecting wiring patterns for connecting the terminals of the composite chip 104 and the terminals of the control ROM 105 are provided near or around the outside of the control ROM arrangement area 192. A wiring pattern is routed in the control ROM placement area 192 through the via, so that the via can be visually recognized from the outside of the substrate without being shielded by the control ROM 105 or the like. Compared to a wiring pattern in which vias are not provided in the vicinity of the outside of the area 192 or around it, confirmation and inspection of the wiring pattern connecting the terminals of the composite chip 104 and the terminals of the control ROM 105 are facilitated. Wiring efficiency can be improved by arranging vias near the outside.

As shown in FIGS. 27 and 28, the vias v69 to v73 are arranged in the control ROM placement area 192 together with other vias. The wiring pattern is drawn out to the control ROM arrangement area 192 via the . In this way, the wiring pattern that connects the vias (v69 to v73) arranged together with the other specific interlayer conductive portions and the terminals of the control ROM 105 is arranged in the control ROM placement area 192 via another via (v103 to v107). can be arranged to increase the wiring efficiency. Even in this case, since the vias v69 to v73 are arranged in the same manner as the other vias, it is possible to relatively easily perform inspections such as confirmation of the connection relationship and checking of energization.

Although the VDP+CPU composite chip 104 is exemplified in the embodiment, a CPU chip without the VDP function may be used. Also, the control ROM is not limited to a storage medium for storing control programs for the CPU, and may be a ROM for storing audio data and image data.

Vias located in the composite chip placement area 191 and the control ROM placement area 192 may be used as test points for continuity check. In this case, it is desirable to display test points (identification information display) by silk printing near or around the vias located in the composite chip placement area 191 and the control ROM placement area 192 . As a result, continuity check of the composite chip 104 and the control ROM 105 can be easily performed, and the composite chip placement area 191 and the control ROM placement area 192 can be used to place silk-printed notations of test points.

As shown in FIG. 42, by connecting the SRESET signal and the WTDOG signal to a common logic integrated circuit IC7, it is possible to appropriately perform reset processing when a reset signal is input due to any reset factor. It's becoming Further, the output information (reset signal) from the logic integrated circuit IC7 is output not only to the composite chip 104 and/or the control ROM 105, but also to the decoders IC13 and IC14 shown in FIG. output from the IO-RST), it is possible to execute the reset process for the liquid crystal display unit 76. FIG. As a result, reset operations can be realized synchronously or at approximately the same timing by hardware such as different electronic components.

Also, in order to reset an external ROM such as a CGROM or a voice ROM, a separate reset signal may be output to the composite chip 104 (output from the DDR-RST in FIG. 42). In this manner, even when the output target is the same composite chip 104, a different reset signal may be output for each reset target. Accordingly, a circuit configuration can be provided in which reset processing can be performed according to the reset target and reset purpose. Further, as shown in FIG. 42, the IO-RST signal and the DDR-RST signal are also signals output from the logic integrated circuit IC7. This is a signal that is triggered by being input to the integrated circuit IC7.

In addition, although the common logic integrated circuit IC7 is used in the embodiment, the present invention is not limited to this, and a plurality of logic integrated circuits may be provided. In this case, different logic integrated circuits may be used for the CPU-RST signal, the IO-RST signal, and the DDR-RST signal, or different logic integrated circuits may be used for the CPU-RST signal, the IO-RST signal, and the DDR-RST signal. It may be configured to use a logic integrated circuit. When a plurality of logic integrated circuits are used in this way, although it is costly, it is possible to prevent a reset signal from being output to all hardware due to a problem. Even in this case, different logic integrated circuits are configured to receive a common SRESET signal and/or WTDOG signal.

As shown in FIG. 19, the terminals of the control ROM 105 include terminals (NC, etc.) that are not connected to the terminals of the composite chip 104. In FIG. A location (region) shifted in the X-axis direction with respect to the location where the NC terminal of the control ROM is located in the region 192, and a location (region) shifted in the X-axis direction with respect to the location where terminals other than the NC terminal are located. , the number of vias arranged in the control ROM arrangement area 192 may be varied. In this way, the space in the control ROM arrangement area 192 may be effectively utilized by varying the number of vias arranged for each corresponding location (area). In addition, of course, the wiring pattern pulled out from the via is connected to the terminals other than the NC terminal, so there is an advantage that the connection distance is shortened when arranging them close to each other. When a wiring pattern drawn from a via drawn out from a position (region) shifted in the X-axis direction with respect to the position where the X-axis is to be connected is connected, the connection distance becomes long, but the wiring space has a relatively large margin. , there is an advantage that routing becomes easy.

Among the vias in the control ROM arrangement area 192, vias that are not directly connected to the terminals of the control ROM (for example, a plurality of vias located between v68 and v74 in FIG. 27) are as shown in FIG. Alternatively, it may be provided at a location (region) shifted in the X-axis direction with respect to locations where terminals other than the NC terminals are located. This is because the wiring pattern is not drawn out from these vias on the first wiring layer L1, so there is little possibility that the wiring space in the control ROM arrangement area 192 will be obstructed. Conversely, it may be provided in a location (area) shifted in the X-axis direction with respect to the location where the NC terminal of the control ROM 105 is located in the control ROM layout area 192 . In this case, a wiring space can be provided by a location (region) shifted in the X-axis direction with respect to locations where terminals other than the NC terminals are located. In any case, in the embodiment, the via arrangement as shown in FIG. 27 is constructed in consideration of the above-mentioned merits and with an awareness of the connection relationship with electronic parts (eg, connectors) other than the control ROM. ing.

In the example of FIG. 27, vias for conducting wiring patterns for transmitting address information are arranged in a predetermined array, and vias for conducting wiring patterns for transmitting data information are arranged in a predetermined array. Although the via arrays are arranged in groups, the vias are not limited to this, and the vias that conduct the wiring patterns for transmitting the address information and the vias that conduct the wiring patterns for transmitting the data information are arranged in a predetermined arrangement. They may be arranged so as to form one via group. In this case, the vias for conducting the wiring patterns that transmit different information can be densely arranged, so that the installation range of the vias can be made relatively small. In addition, like vias v87 to v90 shown in FIG. 27, some vias may be arranged as small groups in the array of vias that conduct wiring patterns for transmitting data information. A via for conducting a wiring pattern for transmitting address information may also have a similar configuration.

In the example of FIG. 27, vias for conducting wiring patterns for transmitting address information and vias for conducting wiring patterns for transmitting data information are arranged in a predetermined arrangement in the control ROM arrangement area 192 . , the vias may be arranged in a predetermined arrangement outside the control ROM arrangement area 192 . In this case, the control ROM arrangement area 192 cannot be utilized, but since the wiring pattern is connected from the outside of the control ROM arrangement area 192 to the terminals of the control ROM 105, check the connection status for each terminal of the control ROM. It has the advantage of being easier. However, since the required wiring space is relatively large compared to the case where the control ROM placement area 192 is used, it is desirable to employ such a configuration when the space is relatively free.

As shown in FIG. 27, the wiring patterns of special terminals such as OE#, WE#, BYTE#, WP#/ACC among the terminals of the control ROM 105 are arranged from the outside of the control ROM arrangement area 192 to the terminals. , the connection status may be easily checked. Also, CE# and RESET# may be configured in the same manner. However, in the embodiment, CE#, which is a chip select input terminal for inputting a chip select signal, and RESET#, which is a reset terminal for inputting a reset signal, are likely to be subject to problems and failures. A wiring pattern is connected to each terminal from within the control ROM placement area 192 so that the pattern is not tampered with.

As shown in FIG. 26, with respect to the terminals of the composite chip 104 and the vias in the composite chip placement area 191, the composite chip terminals are arranged linearly in the Y-axis direction (and/or the X-axis direction). By arranging the vias in the arrangement region 191 in a straight line in the Y-axis direction (and/or the X-axis direction), it is possible to easily confirm the arrangement of each terminal and the arrangement of the vias, and at the same time, the space is reduced. Vias can be arranged in an aligned manner within the composite chip placement area 191, which has relatively little margin.

Also, as shown in FIG. 26, terminals of the composite chip 104 linearly aligned in the Y-axis direction (and/or X-axis direction) and vias linearly aligned in the Y-axis direction (and/or X-axis direction) are preferably arranged so as not to overlap each other in the Y-axis direction (and/or the X-axis direction). By configuring in this way, the vias can be arranged, for example, avoiding the terminals located adjacent to each other or in the vicinity, so that the wiring pattern from the vias can be easily arranged.

Further, as shown in FIG. 26, vias in the composite chip placement region 191 are connected to outer terminals (eg, HAD18, HAD14, HAD10, HAD6, HAD21, HDT12, HDT7, HDT4) arranged near the periphery of the composite chip placement region 191. , HDT0) and/or terminals arranged inside (eg, HAD17, HAD13, HAD9, HAD5, HAD22, HDT13, HDT8, HDT5, HDT1) overlap each other in the X-axis direction (and/or the Y-axis direction). It is desirable to arrange in a position where As a result, the vias can be arranged while avoiding the outer terminals and/or the terminals arranged inside thereof, so that the wiring pattern from the vias can be easily arranged. In other words, in the first wiring layer L1, if the vias are arranged to avoid the outer terminals and/or the terminals arranged inside thereof, when the wiring pattern is pulled out from the vias in a different wiring layer, the outer terminals and/or the inner side of the terminals can be easily connected. It is possible to draw out the wiring pattern linearly in the X-axis direction (and/or the Y-axis direction) without worrying about the terminals arranged in the direction.

Further, the outer terminals (eg, HAD18, HAD14, HAD10, HAD6, HAD21, HDT12, HDT7, HDT4, HDT0) arranged near the outer periphery of the composite chip arrangement area 191 shown in FIG. With respect to vias (eg V11 to V24) arranged to avoid terminals (eg HAD17, HAD13, HAD9, HAD5, HAD22, HDT13, HDT8, HDT5, HDT1), first specific vias (eg v18 to v24) and second specific vias (e.g., v11-v17) located inside the composite chip 104 relative to the first specific vias, avoiding the outer terminals and/or the terminals located inside them. As a result, they are arranged so as to overlap each other in the X-axis direction in the first wiring layer L1. In this case, for the second specific via arranged inside the composite chip 104 than the first specific via, for example, in a wiring layer different from the first wiring layer L1 as shown in FIG. The wiring pattern may be arranged so as to avoid one specific via. In this way, by using a plurality of wiring layers, the wires are arranged inside the composite chip placement region 191 so as to avoid the outer terminals arranged near the outer periphery of the composite chip placement region 191 and/or the terminals arranged inside thereof. A first specific via and a second specific via may be provided, and a wiring pattern drawn out from the second specific via may be provided so as to avoid the first specific via. As a result, the wiring pattern can be efficiently pulled out from inside the composite chip placement area 191 where there is relatively little wiring space to the outside of the composite chip placement area 191 . Further, here, specific terminals and specific vias are shown as examples based on FIGS. 26 and 31, but the configuration is not limited to this, and other terminals and vias may be configured in the same manner. For example, one edge side of the composite chip 104 is shown as an example in FIG. 26, but the other edge side may have the same configuration. In addition, when the first wiring layer L1 in the composite chip placement area 191 has a relatively large wiring space, the first specific via is arranged in the X-axis direction (and/or the Y-axis direction) in the first wiring layer L1. A second specific via may be configured to be placed to avoid.

As described above, the vias in the composite chip placement region 191 shown in FIG. 26 are arranged linearly in the Y-axis direction (and/or the X-axis direction). Even in different wiring layers, the vias in the composite chip placement area 191 are arranged linearly in the Y-axis direction (and/or the X-axis direction). Here, a first via (eg, v21), a second via (eg, v14) positioned inside the composite chip placement region 191 from the first via, and inside the composite chip placement region 191 from the second via The first via extends out of the composite chip placement region 191 by a wiring pattern drawn out linearly in the X-axis direction, and the second via extends to the first via The first wiring pattern drawn out linearly in the X-axis direction via the wiring pattern drawn out by the first distance in the direction avoiding the , and the first wiring pattern drawn out linearly in the direction in which the control ROM 105, which is the connection destination, is located The second wiring pattern advances outside the composite chip placement region 191, and the wiring pattern that the third via is pulled out by the first distance in a direction to avoid the first via and/or the second via (a wiring pattern that avoids the first via from the second via direction) and a wiring pattern drawn out linearly in the Y-axis direction (the wiring pattern length up to this point is the first distance in the direction avoiding the first via from the second via). The first wiring pattern is drawn out linearly in the X-axis direction and the second wiring pattern is drawn out linearly in the direction in which the control ROM 105, which is the connection destination, is located. The wiring pattern is configured to extend outside the composite chip placement area 191 . In this way, when the first via, the second via, and the third via are arranged toward the inside of the composite chip placement region 191 in this order, the outer vias are first placed in the composite chip placement region 191 . A wiring pattern may be provided to avoid this. As a result, the wiring space in the composite chip placement area 191 can be effectively utilized.

In the above example, the relationship between the first via, the second via, and the third via is shown by taking a specific via as an example, but the configuration is not limited to this, and the other vias shown in the figure can have the same configuration. desirable. In this way, by adopting the same configuration at a plurality of locations, it is possible to effectively utilize the wiring space in the composite chip placement area 191 more effectively than implementing at a single location. Also, in the above example, a wiring layer different from the first wiring layer L1 in the composite chip placement area 191 is used, but the present invention is not limited to this and may be implemented in the first wiring layer L1. may However, since a plurality of terminals of the composite chip 104 are arranged on the first wiring layer L1, it is assumed that the wiring space is relatively limited. is desirable.

In the example of FIG. 26, like the terminals of the composite chip 104 from HAD1 to HAD0 arranged linearly in the Y-axis direction, wiring patterns drawn out from the respective terminals are drawn out in different directions (for example, HAD1 and HAD0 are -XY direction, +XY direction for HAD8, HAD3, HAD15 and HAD20, and -X+Y direction for HAD11), vias connected to each terminal are arranged linearly in the Y-axis direction. In this way, the terminals of the composite chip 104 arranged in a straight line in the Y-axis direction (and/or the X-axis direction) and the vias connected by the respective wiring patterns are arranged in a straight line in the Y-axis direction (and/or the X-axis direction). Terminals of the composite chip 104 that are not arranged in a straight line in the Y-axis direction (and/or the X-axis direction) and vias connected by wiring patterns are arranged in the Y-axis direction. (and/or in the X-axis direction). Even with such a configuration, the terminal array and via array of the composite chip 104 can be arranged linearly in the Y-axis direction (and/or the X-axis direction). It is possible to achieve the same effect as

In the example of FIG. 26, from a plurality of terminals (eg, HDT6, HDT10, HDT15, HAD24) of the composite chip 104 arranged in a straight line in the Y-axis direction, wiring patterns are drawn out in substantially the same direction. Vias (eg, v17 to v14) are arranged linearly in the region 191 in the Y-axis direction. As shown in FIG. 31, the first wiring layer L1 is electrically connected to the fourth wiring layer L4 through these vias, and the wiring pattern is led out from the fourth wiring layer L4. In this way, wiring patterns may be drawn out in the same direction from each of the terminals of the composite chip 104 that have common conduction destinations from vias (here, the fourth wiring layer L4). Similarly, vias connected to each terminal may be arranged linearly in the Y-axis direction within the composite chip placement area 191 . In this case, as shown in FIG. 26, an address output terminal for outputting address information and a data input/output terminal for inputting/outputting data information may be configured as described above. The above-described configuration may be configured with only address output terminals for outputting information or only data input/output terminals for inputting/outputting data information. By configuring in this way, it becomes easy to check the arrangement of each terminal, the arrangement of vias, and the wiring pattern serving as a connection path. In addition, not only the terminals of the composite chip 104 that have the same conduction destination (here, the fourth wiring layer L4) from the via, but also the connection from the via to the connection destination (eg, the control ROM 105) through the wiring pattern. The terminals of the composite chip 104 having the same type may be configured as described above. In addition, the wiring route from the via to the connection destination (eg, control ROM 105) through the wiring pattern (which wiring layer is passed through, what wiring pattern is used for wiring, etc.) is substantially common. The terminals of the composite chip 104 may be configured as described above. By configuring in this way, it becomes easy to check the arrangement of each terminal, the arrangement of vias, and the wiring pattern serving as a connection path.

In the above description, the arrangement of vias v60 to v85 and v87 to v107 (specific inter-layer conduction portions) in the control ROM arrangement area 192 is approximated to the arrangement of the corresponding terminals (specific second terminals) on the control ROM 105 side. The word "approximation" is used in this example, but this "approximation" may mean that the arrangement of all the terminals and vias that are in the connection relationship are the same, or that the arrangement of all terminals and vias that are in the connection relationship Some terminals and vias may have the same arrangement. In addition, when there are a plurality of items in a connection relationship (for example, a control ROM terminal and a connector terminal for a predetermined via), the arrangement of one or both of the terminals may be the same. Also, when there are a plurality of connection destinations, there is no problem if they are the same electronic component, but if they are different electronic components, there is a high possibility that the arrangements of both terminals are different. In that case, it is practically impossible to have a via arrangement that completely matches the arrangement of both terminals. Therefore, in order to match the arrangement of both terminals as much as possible, the arrangement may be partially common. For example, a partial arrangement of the terminals of the first connection (partial arrangement of the terminals of the control ROM 105), a partial arrangement of the terminals of the second connection (partial arrangement of the terminals of the connector), and may correspond to a partial arrangement of the terminals of the first connection destination (arrangement of a part of the terminals of the control ROM), but the terminals of the second connection destination (partial arrangement of connector terminals) is not supported However, a second via array corresponding to a partial array of the terminals of the second connection destination (a partial array of the terminals of the connector) may be provided. It is also assumed that such an arrangement of vias has the aforementioned "approximation" relationship.

Regarding the assembly of boards, "assembly" may be a combination of a plurality of boards to complete one control board, or a state in which a harness is inserted into a connector for a single board so that it can conduct electricity. , and may be connected to another substrate via a harness. In addition, it is not limited to a plurality of substrates or a single substrate, and various electronic components required for operation may be attached to the substrate.

The contents of the above embodiments can be combined arbitrarily, and by combining them, the wiring efficiency can be increased more effectively, and a substrate configuration that is resistant to noise and fraud can be obtained.

In addition, all terminal arrangements, wiring patterns, installation positions of electronic components, etc. shown in the drawings were constructed by seeking optimum solutions. , miniaturization of the substrate and noise reduction are possible.

Further, the present invention can be similarly implemented in various pinball game machines such as an arrange ball machine and a mammoth game machine, as well as game machines other than pinball game machines such as slot machines.
