In this example, the fourth protection wall 134 is located above the fourth side wall 109. In this example, a light emitter 84 is attached to the fourth protection wall 134. Specifically, the light emitter 84 is attached to the surface of the fourth protection wall 134 opposite to the surface facing the fourth side wall 109, that is, the surface facing inward of the case 91.

As shown in FIGS. 8 and 9, the first protection wall 131 has one or more protrusions 135. The protrusion 135 is a member for attaching the frame 101 to the holder 102.

The drive unit 141 has one or two drive substrates 142. In this example, the drive unit 141 includes one drive board 142 on which both a panel circuit 143 and a light source circuit 144 are mounted. The drive board 142 is connected to the sub-board 72.

Drive board 142 is attached to case 91. Specifically, drive board 142 is attached to rear surface 93. In this example, the drive board 142 is located along the upper side of the rear wall 121.

The drive substrate 142 is a polygon having multiple sides when the liquid crystal display 51 is viewed from the rear. In this example, drive board 142 has six sides. In this example, the shape of the drive substrate 142 is a concave polygon in which one or more interior angles are larger than 180 degrees. Specifically, in the drive board 142, one interior angle is greater than 180 degrees. In this example, the shape of the drive board 142 is a concave hexagon.

The drive board 142 has a first side 151, a second side 152, a third side 153, a fourth side 154, a fifth side 155, and a sixth side 156.
The first side 151 extends along the upper side of the rear wall 121. In this example, the first side 151 is the uppermost side of the plurality of sides on the drive board 142. In this example, the first side 151 is the longest in the drive board 142. In this example, the length of the first side 151 is the width of the drive board 142. The width of the drive board 142 is smaller than the width of the case 91. That is, the length of the first side 151 is smaller than the length of the upper side of the rear wall 121.

The second side 152 is continuous with the first side 151. The second side 152 is perpendicular to the first side 151.

In the drive board 142, the interior angle formed by the third side 153 and the fourth side 154 is 270 degrees. The other five interior angles are each 90 degrees.
A cutout 157 is formed in the drive board 142. The notch 157 is formed at the edge of the drive board 142. In this example, the notch 157 is formed on the third side 153. The notch 157 is formed to be recessed from the third side 153 when the liquid crystal display 51 is viewed from the rear. The shape of the cutout 157 is rectangular when the liquid crystal display 51 is viewed from the rear.

A plurality of through holes 158 are formed in the drive board 142 for attaching the drive board 142 to the case 91. Therefore, a hole is formed in the case 91 at a position overlapping with the through hole 158. For example, a screw is inserted into the through hole 158. In this example, five through holes 158 are formed in the drive board 142.

The through hole 158 is formed in a portion of the drive board 142 where no circuit is mounted. In this example, a corner portion is formed by the second side 152 and the third side 153, a corner portion is formed by the fourth side 154 and the fifth side 155, a corner portion is formed by the fifth side 155 and the sixth side 156, and a corner portion is formed by the fifth side 155 and the sixth side 156. A through hole 158 is formed at a corner formed by the fifth side 155 and the sixth side 156 and near the center of the drive board 142.

As shown in FIG. 9, the drive board 142 has a component surface 161 on which a circuit is mounted, and a solder surface 162 opposite to the component surface 161. The component surface 161 is a surface of the drive board 142 on which the panel circuit 143 is mounted and a surface on which the light source circuit 144 is mounted. In this example, the component surface 161 is a surface on which both the panel circuit 143 and the light source circuit 144 are mounted. In this example, drive board 142 is attached to case 91 with solder surface 162 in contact with rear surface 93 . Therefore, in this example, the solder surface 162 faces the front, and the component surface 161 faces the rear.

As shown in FIG. 11, in this example, the panel circuit 143 is located above the light source circuit 144. The panel circuit 143 is a circuit that drives the liquid crystal panel 82. The panel circuit 143 has a CPU and memory. The panel circuit 143 is, for example, a timing controller, so-called T-Con. Panel circuit 143 is connected to sub-control circuit 74 . The panel circuit 143 changes the orientation of the liquid crystal layer for each pixel based on the signal received from the sub-control circuit 74. The panel circuit 143 is connected to the liquid crystal panel 82 by a panel cable 171, which will be described later.

The light source circuit 144 is a circuit that drives the light source 83. The light source circuit 144 has a CPU and memory. The light source circuit 144 is, for example, an LED driver. The light source circuit 144 is connected to the sub control circuit 74. The light source circuit 144 controls the light amount of the light emitting body 84 by, for example, PWM control based on the signal received from the sub control circuit 74.

The drive unit 141 has a plurality of connectors. A plurality of connectors are attached to drive board 142. The plurality of connectors are connected to a circuit mounted on the drive board 142, that is, a panel circuit 143 or a light source circuit 144. A plurality of connectors are located on the edge of the drive board 142. In this example, since the drive board 142 includes six edges, the plurality of connectors include the first side 151, the second side 152, the third side 153, the fourth side 154, the fifth side 155, and the sixth side. 156. In this example, at least two of the plurality of connectors are located on the same side of the drive board 142.

The drive unit 141 has a panel connector 163 as part of the plurality of connectors. The panel connector 163 is a connector for connecting the panel circuit 143 and the sub-control circuit 74. That is, the panel connector 163 is a connector for connecting the drive board 142 and the sub-board 72.

Panel connector 163 is connected to panel circuit 143. Panel connector 163 is located on third side 153. In this example, the panel connector 163 is attached to the drive board 142 so as to be fitted into the notch 157. Thereby, the thickness of the drive section 141 can be made smaller than when the panel connector 163 is mounted on the component surface 161. That is, the liquid crystal display 51 can be made thinner.

Panel connector 163 is connected to a cable extending from sub-board 72. The panel connector 163 has an insertion port 164 into which the cable is inserted. In this example, the insertion port 164 faces downward. The insertion port 164 may face upward.

In the gaming machine 11, the liquid crystal display 51 has significantly increased in size. Therefore, the width of the liquid crystal display 51 is close to the width of the gaming machine 11. In this case, if the insertion port 164 faces to the right or left when the liquid crystal display 51 is viewed from the rear, the cable connected to the panel connector 163 may be bent so as to be folded back. . In such a case, a load is likely to be applied to the panel connector 163. In this regard, if the insertion port 164 faces upward or downward, the load on the panel connector 163 can be reduced. Furthermore, it becomes easier to route the cable connected to the panel connector 163.

The drive unit 141 includes a light source connector as part of the plurality of connectors. The drive unit 141 has two light source connectors. Specifically, the drive unit 141 includes an input light source connector 165 and an output light source connector 166. In this example, the input light source connector 165 and the output light source connector 166 are located on the same side of the drive board 142. Specifically, the input light source connector 165 and the output light source connector 166 are located on the fifth side 155. The input light source connector 165 is an input connector for the light source circuit 144. The output light source connector 166 is an output connector for the light source circuit 144.

The input light source connector 165 is a connector for connecting the light source circuit 144 and the sub-control circuit 74. That is, the input light source connector 165 is a connector for connecting the drive board 142 and the subboard 72. Input light source connector 165 is connected to light source circuit 144 . In this example, the input light source connector 165 is mounted on the component surface 161. Like the panel connector 163, the input light source connector 165 may be attached to the drive board 142 so as to be fitted into a notch. In this case, the liquid crystal display 51 can be made thin.

The input light source connector 165 is connected to a cable extending from the sub-board 72. Input light source connector 165 has a socket 167 into which the cable is inserted. In this example, the insertion port 167 faces downward. The insertion port 167 may face upward.

Similarly to the panel connector 163, the load on the input light source connector 165 can be reduced if the insertion port 167 of the input light source connector 165 faces upward or downward. Furthermore, it becomes easier to route the cable connected to the input light source connector 165.

The output light source connector 166 is a connector for connecting the light source circuit 144 and the light emitter 84. Output light source connector 166 is connected to light source circuit 144 . The output light source connector 166 is connected to a light source cable 172, which will be described later. In this example, the output light source connector 166 is mounted on the component surface 161. Similarly to the panel connector 163, the output light source connector 166 may be attached to the drive board 142 so as to be fitted into a notch. In this case, the liquid crystal display 51 can be made thin.

The output light source connector 166 has an insertion port 168 into which the light source cable 172 is inserted. In this example, the receptacle 168 faces downward. The insertion port 168 may face upward.
Similarly to the panel connector 163, if the insertion port 168 of the output light source connector 166 faces upward or downward, the load on the output light source connector 166 can be reduced. Furthermore, it becomes easier to route the light source cable 172.

In this example, the distance corresponding to the width of one connector that is the widest among the plurality of connectors attached to the drive board 142 is the predetermined distance L1. That is, the distance corresponding to the width of the largest connector among the panel connector 163, the input light source connector 165, and the output light source connector 166 is the predetermined distance L1. In this example, among the panel connector 163, the input light source connector 165, and the output light source connector 166, the panel connector 163 has the largest width. Therefore, in this example, the predetermined distance L1 is a distance corresponding to the width of the panel connector 163.

Liquid crystal display 51 has a plurality of connection cables. The connection cable is a cable connected to the liquid crystal module 81 and the drive section 141. The plurality of connection cables include one or more panel cables 171 and one light source cable 172. In this example, the plurality of connection cables include six panel cables 171 and one light source cable 172.

The panel cable 171 is a cable connected to the panel circuit 143 and the liquid crystal panel 82. The panel cable 171 is, for example, a flexible flat cable. In this example, panel cable 171 extends from the edge of drive board 142. Specifically, the panel cable 171 extends from the first side 151 of the drive board 142. The plurality of panel cables 171 are attached to the drive board 142 so as to be lined up on the first side 151 at predetermined intervals.

As shown in FIG. 9, the panel cable 171 extends to pass between the frame 101 and the holder 102. Specifically, the panel cable 171 passes between the first side wall 106 and the first protective wall 131. Thereby, the panel cable 171 extends from the outside of the case 91 toward the inside of the case 91. In order to facilitate passage of the panel cable 171 between the frame 101 and the holder 102, the case 91 may include a spacer between the frame 101 and the holder 102. In this case, since a gap is secured between the frame 101 and the holder 102 by the spacer, the panel cable 171 can easily pass between the first side wall 106 and the first protection wall 131.

As shown in FIG. 8, the plurality of panel cables 171 extend so as to pass between the protrusions 135 when the liquid crystal display 51 is viewed from a position facing the first side surface 94. Specifically, some of the panel cables 171 among the plurality of panel cables 171 extend so as to pass between the protrusions 135 when the liquid crystal display 51 is viewed from above. In this example, four panel cables 171 out of six panel cables 171 pass between the protrusions 135. That is, the panel cable 171 extends so as not to overlap the fixing hole 116.

The plurality of panel cables 171 extend from the inside of the case 91 to the outside of the case 91 so as to pass between the mounting holes 117 when the liquid crystal display 51 is viewed from the rear. Specifically, some of the panel cables 171 among the plurality of panel cables 171 pass between the attachment holes 117. In this example, four panel cables 171 out of six panel cables 171 pass between the attachment holes 117. In this example, the four panel cables 171 that pass between the attachment holes 117 coincide with the four panel cables 171 that pass between the protrusions 135.

As shown in FIG. 6, the light source cable 172 is a cable connected to the output light source connector 166 and the light emitter 84. That is, the light source cable 172 is connected to the light source circuit 144 and the light source 83. The light source cable 172 is connected to the light emitter 84 through the passage port 122.

As shown in FIG. 11, in this example, since the insertion port 168 faces downward and the passage port 122 is located below the drive board 142 in the rear wall 121, it is easy to route the light source cable 172.

As shown in FIG. 12, the liquid crystal display 51 has a cover 181. Cover 181 is attached to case 91. Specifically, the cover 181 is attached to the rear surface 93. The cover 181 is located along the upper side of the rear wall 121 when the liquid crystal display 51 is viewed from the rear.

Specifically, in the opposing portion 182, one interior angle is greater than 180 degrees. In this example, the shape of the opposing portion 182 is a concave hexagon. In this example, the facing portion 182 is configured to have a shape that is one size larger than the drive board 142.

The opposing portion 182 has a first side 183, a second side 184, a third side 185, a fourth side 186, a fifth side 187, and a sixth side 188.
The first side 183 extends along the upper side of the rear wall 121. In this example, the first side 183 is the uppermost side among the plurality of sides in the opposing portion 182. In this example, the first side 183 is the longest in the opposing portion 182. In this example, the length of the first side 183 is the width of the opposing portion 182. The width of the opposing portion 182 is smaller than the width of the case 91. That is, the length of the first side 183 is smaller than the length of the upper side of the rear wall 121.

The second side 184 is continuous with the first side 183. The second side 184 is perpendicular to the first side 183.

The sixth side 188 is continuous with the fifth side 187 and the first side 183. The sixth side 188 is perpendicular to the first side 183, the third side 185, and the fifth side 187, and parallel to the second side 184 and the fourth side 186.

In the opposing portion 182, the interior angle formed by the third side 185 and the fourth side 186 is 270 degrees. The other five interior angles are each 90 degrees.
One or more notches are formed in the cover 181. In this example, the cover 181 has a plurality of notches formed therein. A plurality of cutouts are formed on the edge of the opposing portion 182. The plurality of cutouts are formed to correspond to the plurality of connectors that the drive section 141 has. Therefore, in this example, three notches are formed in the facing portion 182. Specifically, a first notch 191 , a second notch 192 , and a third notch 193 are formed in the facing portion 182 .

The first notch 191 is formed on the third side 185. The first notch 191 is formed to divide the third side 185. In this example, the shape of the first notch 191 is a trapezoid when the liquid crystal display 51 is viewed from the rear. The first notch 191 is formed to be recessed from the third side 185 toward the panel connector 163 when the liquid crystal display 51 is viewed from the rear. Therefore, the first notch 191 corresponds to the panel connector 163. The first notch 191 indicates the position of the panel connector 163.

The second notch 192 is formed on the fifth side 187. The second notch 192 is formed to divide the fifth side 187. In this example, the shape of the second notch 192 is a trapezoid when the liquid crystal display 51 is viewed from the rear. The second notch 192 is formed to be recessed from the fifth side 187 toward the light source connector when the liquid crystal display 51 is viewed from the rear. Specifically, the second notch 192 is formed to be recessed from the fifth side 187 toward the input light source connector 165 when the liquid crystal display 51 is viewed from the rear.

The second cutout 192 exposes the light source connector. Specifically, the second cutout 192 exposes the input light source connector 165. In this way, the second cutout 192 corresponds to the input light source connector 165. The second notch 192 indicates the position of the input light source connector 165.

The third notch 193 is formed on the fifth side 187. The third notch 193 is formed to divide the fifth side 187. The shape of the third notch 193 is trapezoidal when the liquid crystal display 51 is viewed from the rear. The third notch 193 is formed to be recessed toward the light source connector from the fifth side 187 when the liquid crystal display 51 is viewed from the rear. Specifically, the third notch 193 is formed to be recessed from the fifth side 187 toward the output light source connector 166 when the liquid crystal display 51 is viewed from the rear.

The third cutout 193 exposes the light source connector. Specifically, the third cutout 193 exposes the output light source connector 166. In this way, the third cutout 193 corresponds to the output light source connector 166. The third notch 193 indicates the position of the output light source connector 166.

In this example, the first notch 191, the second notch 192, and the third notch 193 form the first side 183, the second side 184, the third side 185, the fourth side 186, the fifth side 187, and the sixth side. A side different from side 188 is formed in opposing portion 182 . Therefore, in this example, the facing portion 182 has a first cut edge in addition to the first side 183, the second side 184, the third side 185, the fourth side 186, the fifth side 187, and the sixth side 188. It has a side due to the notch 191, a side due to the second notch 192, and a side due to the third notch 193.

In this example, the opposing portion 182 has a seventh side 194, an eighth side 195, and a ninth side 196 as sides formed by the first notch 191. The seventh side 194 and the ninth side 196 are continuous with the third side 185. Specifically, of the two third sides 185 separated by the first notch 191, one and the seventh side 194 are continuous, and the other and the ninth side 196 are continuous. In this example, the seventh side 194 and the ninth side 196 are the first side 183, the second side 184, the third side 185, the fourth side 186, and the fifth side when the liquid crystal display 51 is viewed from the rear. 187 and the sixth side 188. The eighth side 195 is continuous with the seventh side 194 and the ninth side 196. The eighth side 195 is parallel to the first side 183, the third side 185, and the fifth side 187, and is perpendicular to the second side 184, the fourth side 186, and the sixth side 188.

Opposing portion 182 has a first opposing portion 198 and a second opposing portion 199. The first opposing portion 198 includes a first side 183, a second side 184, a third side 185, a fourth side 186, a fifth side 187, a sixth side 188, a seventh side 194, an eighth side 195, and a ninth side. 196, a side formed by the second notch 192 and a side formed by the third notch 193. The first opposing portion 198 is a portion of the opposing portion 182 that does not contact the drive unit 141 . Therefore, the first opposing portion 198 is spaced apart from the drive substrate 142. Therefore, a space is formed between the first opposing portion 198 and the drive substrate 142.

When a load is applied to the first opposing portion 198, the first opposing portion 198 may deform. When the deformed first facing portion 198 contacts the drive board 142, a load is applied to the drive board 142. In this regard, in this example, since the first opposing portion 198 is separated from the drive substrate 142, the possibility that the first opposing portion 198 will come into contact with the drive substrate 142 is reduced. That is, the possibility that a load will be applied to the panel circuit 143 and the light source circuit 144 is reduced. Therefore, the panel circuit 143 and the light source circuit 144 are protected.

Since the first facing portion 198 is separated from the drive board 142, the drive board 142 and the cover 181 are insulated. In the first facing portion 198, an insulating sheet may be attached to the surface facing the drive board 142. In this case, drive board 142 and cover 181 are further insulated.

The second opposing portion 199 is a portion that is recessed toward the drive board 142 from the first opposing portion 198 . That is, the second opposing portion 199 is a portion that protrudes from the first opposing portion 198 toward the drive board 142. The second opposing portion 199 is adjacent to the first notch 191 . The second opposing portion 199 constitutes the eighth side 195.

As shown in FIG. 10, the second facing portion 199 faces the panel connector 163. Second opposing portion 199 contacts panel connector 163 . The second opposing portion 199 contacts the panel connector 163 so as to press the panel connector 163 against the rear surface 93 . Thereby, when a load is applied to the cover 181, the panel connector 163 supports the cover 181. This reduces the possibility that the cover 181 will deform. Specifically, when a load is applied to the first opposing portion 198, the panel connector 163 receives the load via the second opposing portion 199. This reduces the possibility that the first opposing portion 198 will deform. Therefore, the possibility that the first facing portion 198 comes into contact with the drive substrate 142 is reduced.

The second opposing portion 199 covers the panel connector 163. That is, when viewing the liquid crystal display 51 from the rear, the panel connector 163 is shielded by the second opposing portion 199. Therefore, it may be difficult to connect the cable to the panel connector 163. In this regard, in this example, the position of the panel connector 163 is indicated by the first notch 191. This makes it easy to connect the cable to the panel connector 163 even when the panel connector 163 is shielded by the second facing portion 199.

As shown in FIG. 12, the cover 181 has legs 201. Leg portion 201 extends from the edge of opposing portion 182 toward rear surface 93 . Specifically, the leg portion 201 extends from the edge of the first opposing portion 198 toward the rear surface 93. In this example, the leg portion 201 extends from each of the second side 184, the third side 185, the fourth side 186, the fifth side 187, the sixth side 188, the seventh side 194, and the ninth side 196.

The legs 201 contact the rear surface 93. Thereby, the opposing portion 182 and the rear wall 121 are maintained at a predetermined distance apart. That is, a space is formed between the cover 181 and the drive board 142. Specifically, a space is formed between the first opposing portion 198 and the drive substrate 142.

The leg portion 201 contacts the receiving portion. Specifically, some of the plurality of leg parts 201 contact the first receiving part 123, the second receiving part 124, and the third receiving part 125. In this example, the leg portion 201 contacts the first receiving portion 123, the second receiving portion 124, and the third receiving portion 125 from above. Thereby, the cover 181 is supported by the receiving portion.

In this example, among the plurality of legs 201 , the leg 201 that comes into contact with the first receiving part 123 is the first leg 202 . Among the plurality of legs 201 , the leg 201 that comes into contact with the second receiving part 124 is the second leg 203 . Among the plurality of legs 201 , the leg 201 that comes into contact with the third receiving part 125 is the third leg 204 .

The first leg portion 202 is the leg portion 201 extending from the third side 185. The first leg portion 202 extends from one of the two third sides 185 separated by the first notch 191 that is continuous with the second side 184 .

The second leg portion 203 is the leg portion 201 extending from the fifth side 187. The second leg portion 203 extends from the side continuous with the fourth side 186 among the three fifth sides 187 divided by the second notch 192 and the third notch 193 .

The third leg portion 204 is the leg portion 201 extending from the fifth side 187. The third leg portion 204 is formed from the side located between the second notch 192 and the third notch 193 among the three fifth sides 187 divided by the second notch 192 and the third notch 193. Extends.

As shown in FIG. 10, the first leg portion 202 has a first leg portion 206 and a second leg portion 207. Not only the first leg part 202 but also the second leg part 203 and the third leg part 204 have a first leg part 206 and a second leg part 207. In this example, the legs 201 other than the leg 201 extending from the second side 184 and the leg 201 extending from the fifth side 187 include a first leg portion 206 and a second leg portion 207. The leg portion 201 extending from the second side 184 and the leg portion 201 extending from the fifth side 187 have only the first leg portion 206 and do not have the second leg portion 207.

First leg portion 206 extends from the edge of opposing portion 182. In particular, first leg portion 206 extends from the edge of first opposing portion 198 . First leg portion 206 extends forward from opposing portion 182 toward rear surface 93 .

Second leg portion 207 extends from the distal end of first leg portion 206 . The second leg portion 207 extends from the first leg portion 206 in a bent manner. The second leg portion 207 extends along the rear surface 93. In this example, second leg portion 207 extends downward.

In the first leg 202 , the second leg 203 , and the third leg 204 , the second leg portion 207 is inserted between the rear surface 93 and the second receiving portion 127 . As a result, second leg portion 207 contacts first receiving portion 126 . The second leg portion 207 contacts the first receiving portion 126 so that the receiving portion supports the cover 181. The second leg portion 207 comes into contact with the second receiving portion 127, thereby reducing the possibility that the cover 181 will come off from the case 91.

The width of the second leg portion 207 is wider than the width of the first receiving portion 126. That is, regarding the first leg portion 202 and the first receiving portion 123, the width of the second leg portion 207 is wider than the width of the first receiving portion 126. Regarding the second leg portion 203 and the second receiving portion 124, the width of the second leg portion 207 is wider than the width of the first receiving portion 126. Regarding the third leg portion 204 and the third receiving portion 125, the width of the second leg portion 207 is wider than the width of the first receiving portion 126. Thereby, even if the cover 181 shifts from side to side when the liquid crystal display 51 is viewed from the rear, the contact between the leg portions 201 and the receiving portions is maintained. Therefore, the receiving part easily supports the leg part 201.

As shown in FIGS. 8 and 9, the cover 181 has one or more hooks 211. In this example, the hook 211 is a member for attaching the cover 181 to the case 91. Hook 211 extends from the edge of opposing portion 182. Specifically, the hook 211 extends from the edge of the first opposing portion 198. In this example, the hook 211 extends from the first side 183.

Hook 211 is inserted into attachment hole 117. Thereby, the cover 181 is attached to the case 91. Specifically, the hook 211 is inserted into the mounting hole 117 so as to go inward of the case 91 . That is, in this example, the hook 211 is inserted into the attachment hole 117 from above. The hook 211 is inserted into the attachment hole 117 so as to fill the step 111.

The number of hooks 211 corresponds to the number of attachment holes 117. Therefore, in this example, the cover 181 has four hooks 211. The four hooks 211 are located in a line on the first side 183 with predetermined intervals.

Hook 211 has a first hook portion 212 and a second hook portion 213. The first hook portion 212 extends forward from the edge of the opposing portion 182. In particular, the first hook portion 212 extends from the edge of the first opposing portion 198. The second hook portion 213 extends from the distal end of the first hook portion 212. The second hook portion 213 extends from the first hook portion 212 in a bent manner. In this example, the second hook portion 213 extends downward. The second hook portion 213 is inserted into the mounting hole 117.

The width of the second hook portion 213 is narrower than the width of the attachment hole 117. In this case, it becomes easier to insert the second hook portion 213 into the attachment hole 117 than when the width of the second hook portion 213 and the width of the attachment hole 117 match.

Hook 211 has a hook surface 214. Hook surface 214 is a surface extending from the edge of opposing portion 182. Hook surface 214 faces outwardly on hook 211 . In this example, hook surface 214 faces upwardly. The hook surface 214 is flush with the first surface 112. Therefore, the edge of the opposing portion 182 is flush with the first surface 112. Thereby, the hook 211 does not protrude from the first surface 112, so that the liquid crystal display 51 can be configured compactly.

In this example, the cover 181 is attached to the case 91 by supporting the leg portions 201 on the receiving portions and inserting the hooks 211 into the attachment holes 117. In this case, the cover 181 is less likely to come off from the case 91 than when the cover 181 is attached to the case 91 using only one of the legs 201 or the hooks 211.

As shown in FIGS. 12 and 13, the cover 181 has one or more protrusions 221. As shown in FIGS. The protrusion 221 protrudes from the opposing portion 182. Specifically, the protrusion 221 protrudes from the first opposing portion 198 toward the drive board 142. The protruding portion 221 protrudes from the first opposing portion 198 in a recessed manner. The protruding portion 221 protrudes from the first opposing portion 198 in a truncated conical shape.

The tip of the protrusion 221 contacts the drive board 142. The protrusion 221 contacts the component surface 161. The protruding portion 221 contacts a portion of the component surface 161 where no circuit is mounted. That is, the protruding portion 221 contacts a portion of the component surface 161 where the panel circuit 143 and the light source circuit 144 are not mounted. For example, the protrusion 221 contacts the periphery of the through hole 158. It can also be said that the protrusion 221 extends toward the through hole 158.

The protruding portion 221 separates the opposing portion 182 from the rear wall 121 by contacting the drive board 142 . That is, like the leg portions 201, the protrusion portions 221 form a space between the facing portion 182 and the drive board 142. Therefore, when a load is applied to the cover 181, the drive board 142 receives the load via the protrusion 221. This reduces the possibility that the cover 181 will deform. Therefore, the possibility that the cover 181 comes into contact with the panel circuit 143 or the light source circuit 144 is reduced.

In this example, the number of protrusions 221 corresponds to the number of through holes 158. Therefore, in this example, the cover 181 has five protrusions 221. The protrusion 221 is located at a position overlapping the through hole 158 when the liquid crystal display 51 is viewed from the rear.

In this example, the five protrusions 221 are located in the cover 181 near the second side 184, near the corner between the third side 185 and the fourth side 186, near the corner between the fifth side 187 and the sixth side 188, It is located near the corner between the sixth side 188 and the first side 183, and near the center point C1 of the cover 181. The center point C1 is a point indicating the center position of the cover 181 when the liquid crystal display 51 is viewed from the rear.

At least one of the plurality of protrusions 221 is located within a predetermined distance L1 from one of the plurality of connectors included in the drive unit 141 when the liquid crystal display 51 is viewed from the front. Good too. In this example, the distance between the protrusion 221 located near the corner of the fifth side 187 and the sixth side 188 and the output light source connector 166 is a specific distance L2. The specific distance L2 is smaller than the predetermined distance L1. Therefore, the protrusion 221 located near the corner of the fifth side 187 and the sixth side 188 is located within the predetermined distance L1 from the output light source connector 166. However, the present invention is not limited to this, and other protrusions 221 may be located within a predetermined distance L1 from any connector.

In the drive board 142, a load is likely to be applied to the vicinity of the connector when a cable is connected to the connector. Therefore, in the drive board 142, the vicinity of the connectors, that is, the vicinity of the panel connector 163, the vicinity of the input light source connector 165, and the vicinity of the output light source connector 166 are likely to be displaced when connecting cables. In particular, when a cable is inserted into the connector, the drive board 142 tends to lift off from the rear surface 93 due to the load applied to the connector. In this case, there is a risk that the panel circuit 143 and the light source circuit 144 may come into contact with the cover 181.

In this regard, by locating the protrusion 221 near the connector, the protrusion 221 can effectively press the drive board 142. In this example, since the protrusion 221 is located near the output light source connector 166, it is possible to reduce the possibility that the area around the output light source connector 166 will be displaced. Thereby, the space formed between the drive board 142 and the cover 181 is maintained.

At least one of the plurality of protrusions 221 is located vertically between one of the plurality of connectors and the center line D1 when the liquid crystal display 51 is viewed from the rear. In this example, the protrusion 221 located near the corner between the fourth side 186 and the fifth side 187 and the protrusion 221 located near the corner between the fifth side 187 and the sixth side 188 are connected to the input light source connector. 165 and between the output light source connector 166 and the centerline D1. Specifically, when the liquid crystal display 51 is viewed from the rear, the center position of the protrusion 221 located near the corner between the fourth side 186 and the fifth side 187 is located above the light source connector, and the center line D1 located below. The center position of the protrusion 221 located near the corner of the fifth side 187 and the sixth side 188 is located above the light source connector and below the center line D1. The center line D1 is an imaginary line that divides the cover 181 into two vertically when the liquid crystal display 51 is viewed from the rear. The center line D1 passes through the center point C1 and extends left and right when the liquid crystal display 51 is viewed from the rear.

One or more insertion holes 222 are formed in the cover 181. The insertion hole 222 is a hole into which a screw 223 for fixing the cover 181 to the case 91 is inserted. Therefore, the insertion hole 222 overlaps with the through hole 158. Therefore, the number of insertion holes 222 corresponds to the number of through holes 158. That is, in this example, the number of insertion holes 222 corresponds to the number of protrusions 221. In this example, five insertion holes 222 are formed in the cover 181. In this example, the insertion hole 222 is formed in the protrusion 221 . The insertion hole 222 opens at the tip of the protrusion 221 .

As shown in FIG. 13, the case 91 is formed with a screw hole 224 into which a screw 223 is inserted. A screw hole 224 is formed in the rear wall 121. The insertion hole 222 overlaps the through hole 158 and the screw hole 224. The screw 223 is fastened to the screw hole 224.

Next, the functions and effects of the above embodiment will be explained.
(1) The second opposing portion 199 faces and contacts the panel connector 163. Panel connector 163 supports cover 181 by contacting second opposing portion 199 . Therefore, when a load is applied to the cover 181, the possibility that the cover 181 deforms is reduced. Therefore, the cover 181 protects the circuit mounted on the drive board 142.

(2) The cover 181 forms a space between the drive board 142 and the first opposing portion 198 by the leg portions 201 coming into contact with the rear surface 93 . That is, the drive substrate 142 and the first opposing portion 198 are separated from each other. Therefore, even if the cover 181 is deformed due to a load being applied to the cover 181, the first opposing portion 198 is unlikely to come into contact with the drive board 142.

(3) The protruding portion 221 contacts a portion of the drive board 142 where the panel circuit 143 and the light source circuit 144 are not mounted. According to this, when the protrusion 221 contacts the drive board 142 and a load is applied to the cover 181, the possibility that the cover 181 is deformed is reduced. Since the protrusion 221 contacts a portion of the drive board 142 that does not interfere with the panel circuit 143 and the light source circuit 144, the panel circuit 143 and the light source circuit 144 are protected by the cover 181.

(4) A second notch 192 and a third notch 193 are formed in the cover 181 to expose the light source connector. According to this, the input light source connector 165 and the output light source connector 166 are exposed. Therefore, it is easy to connect the cable extending from the sub-board 72 to the input light source connector 165. Furthermore, it is easy to connect the light source cable 172 to the output light source connector 166.

(5) The cover 181 has a facing portion 182 facing the drive board 142, a hook 211 extending from the edge of the facing portion 182, and a leg portion 201 extending from the edge of the facing portion 182 toward the rear surface 93. The cover 181 is attached to the case 91 by inserting the hook 211 into the attachment hole 117 and by bringing the leg portion 201 into contact with the receiving portion. In this case, the cover 181 is attached to the case 91 using two elements: the hook 211 and the leg portion 201. According to this, the cover 181 is less likely to come off from the case 91 than when the cover 181 is attached to the case 91 using either the hook 211 or the leg portion 201. Therefore, the cover 181 protects the circuit mounted on the drive board 142.

(6) The receiving portion protrudes from the rear surface 93 and contacts the leg portion 201 to contact the cover 181 from below. The hook 211 is inserted into the mounting hole 117 so as to go inward of the case 91 . According to this, the cover 181 is supported from below by the case 91 due to the hook 211 being inserted into the attachment hole 117 and the leg portion 201 coming into contact with the receiving portion. That is, the case 91 receives the load of the cover 181 due to gravity. This makes it difficult for the cover 181 to come off from the case 91.

(7) The width of the second leg portion 207 is wider than the width of the first receiving portion 126. According to this, the receiving part can easily support the leg part 201. This makes it difficult for the cover 181 to come off the case 91.

(8) When the hook 211 is inserted into the mounting hole 117 toward the inside of the case 91, the cover 181 is installed in a state where the edge of the facing portion 182 and the first surface 112 are flush with each other. It can be attached to 91. According to this, when the liquid crystal display 51 is viewed from the rear, the edge of the opposing portion 182 does not protrude from the side surface of the case 91. Therefore, for example, when assembling the gaming machine 11, the possibility that the cover 181 will come off from the case 91 due to the edge of the facing portion 182 getting caught on another member is reduced. Therefore, the cover 181 protects the circuit mounted on the drive board 142.

(9) The width of the attachment hole 117 is wider than the width of the second hook portion 213. According to this, it is easy to insert the second hook portion 213 into the mounting hole 117. Therefore, it is easy to attach the cover 181 to the case 91.

(10) The panel cable 171 extends from the outside of the case 91 to the inside of the case 91 so as to pass between the mounting holes 117 when the liquid crystal display 51 is viewed from a position facing the first side surface 94. According to this, the panel cable 171 is less likely to interfere with the hook 211. Therefore, a load is less likely to be applied to the panel cable 171. This reduces the load on the panel circuit 143 connected to the panel cable 171. Therefore, the circuit mounted on the drive board 142 is protected.

(11) The panel cable 171 extends from the outside of the case 91 toward the inside of the case 91 by passing between the frame 101 and the holder 102. According to this, the panel cable 171 can be routed from the outside of the case 91 to the inside of the case 91 without providing a hole in the case 91 for the panel cable 171 to pass through.

(12) The panel cable 171 passes between the frame 101 and the holder 102 so as not to overlap the fixing hole 116 when the liquid crystal display 51 is viewed from a position facing the first side surface 94. According to this, the panel cable 171 is less likely to interfere with the protrusion 135 inserted into the fixing hole 116. Therefore, a load is less likely to be applied to the panel cable 171.

(13) At least one of the plurality of protrusions 221 is located within a predetermined distance L1 from one of the plurality of connectors when the liquid crystal display 51 is viewed from the rear. Load is likely to be applied to the vicinity of the connector on the drive board 142 when a cable is connected to the connector. Therefore, the area around the connector on the drive board 142 is likely to be displaced when the cable is connected.

According to this, the protrusion 221 is located closer to the connector than in the case where the protrusion 221 is located farther from the connector than the predetermined distance L1. By locating the protrusion 221 close to the connector, the possibility that the area around the connector on the drive board 142 will be displaced when the cable is attached or detached is reduced. In this example, the protrusion 221 located near the corner of the fifth side 187 and the sixth side 188 is located close to the output light source connector 166. This reduces the possibility that the area around the output light source connector 166 on the drive board 142 will be displaced when the light source cable 172 is connected. As a result, the space formed between the component surface 161 and the cover 181 is maintained. Therefore, the panel circuit 143 and the light source circuit 144 are protected.

(14) At least one of the plurality of protrusions 221 is located between one of the plurality of connectors and the center line D1 in the upper and lower directions when the liquid crystal display 51 is viewed from the rear. . In this example, the protrusion 221 located near the corner between the fourth side 186 and the fifth side 187 and the protrusion 221 located near the corner between the fifth side 187 and the sixth side 188 are vertically arranged as follows. It is located between the light source connector and the center line D1. According to this, the space formed between the component surface 161 and the cover 181 can be easily maintained by the protruding portion 221. This protects the panel circuit 143 and light source circuit 144.

(15) The connector has a socket into which the cable is inserted. That is, the panel connector 163 has an insertion port 164, the input light source connector 165 has an insertion port 167, and the output light source connector 166 has an insertion port 168. The insertion ports 164, 167, 168 face upward or downward.

In the gaming machine 11, the liquid crystal display 51 has significantly increased in size. Therefore, the difference between the width of the gaming machine 11 and the width of the liquid crystal display 51 is reduced. That is, the width of the liquid crystal display 51 is close to the width of the gaming machine 11. In this case, if the insertion ports 164, 167, and 168 face leftward or rightward, the cables connected to the connectors tend to pop out from the leftward or rightward side of the liquid crystal display 51. When the insertion ports 164, 167, and 168 face leftward or rightward, in order to accommodate the cable inside the gaming machine 11, it is necessary to bend the cable back. When the cable is bent back, stress is placed on the connector. If a load is applied to the connector, the panel circuit 143 and the light source circuit 144 may be affected.

According to the above configuration, the cable connected to the connector is less likely to protrude from the left or right side of the liquid crystal display 51, compared to the case where the insertion ports 164, 167, and 168 face left or right. Therefore, there is little risk of bending the cable back. In other words, there is little possibility that a load will be applied to the connector. This protects the panel circuit 143 and light source circuit 144. Therefore, the circuit mounted on the drive board 142 is protected.

(16) At least two of the plurality of connectors are located on the same side of the drive board 142. In this example, the input light source connector 165 and the output light source connector 166 are located on the fifth side 187. According to this, it is easier to connect cables to two connectors located on the same side, compared to a case where a plurality of connectors are located on different sides of the drive board 142.

The above embodiment can be modified and implemented as follows. The above embodiments and the following modifications can be implemented in combination with each other within a technically consistent range.
- As shown in FIG. 11, the case 91 includes a fourth receiving part 231 and a fifth receiving part 232 in addition to the first receiving part 123, the second receiving part 124, and the third receiving part 125. Good too. The fourth receiving section 231 and the fifth receiving section 232 have the same configuration as the first receiving section 123, the second receiving section 124, and the third receiving section 125.

The fourth receiving portion 231 and the fifth receiving portion 232 protrude from the rear wall 121. In this modified example, the fourth receiving part 231 and the fifth receiving part 232 are located above the second receiving part 124 and the third receiving part 125.

The fourth receiving part 231 and the fifth receiving part 232 are in contact with the drive board 142. Specifically, the fourth receiving part 231 and the fifth receiving part 232 contact the edge of the drive board 142. In this modification, the fourth receiving portion 231 and the fifth receiving portion 232 are in contact with the fifth side 155. The fourth receiving part 231 and the fifth receiving part 232 support the driving board 142 by coming into contact with the driving board 142. Thereby, the screw 223 can be inserted into the through hole 158 while the receiving part supports the drive board 142 from below. Therefore, according to this modification, it is easy to attach the drive board 142 to the case 91.

- As shown in FIG. 14, the drive board 142 may be attached to the case 91 with the component surface 161 facing the rear surface 93. That is, the drive board 142 may be attached to the case 91 with the component surface 161 and the solder surface 162 opposite to those in the above embodiment. In this modified example, the protrusion 221 is included in the case 91 instead of the cover 181. That is, the protrusion 221 protrudes rearward from the rear wall 121. The space formed between the component surface 161 and the case 91 is maintained by the protrusion 221 . A screw hole 224 is formed in the protrusion 221 . A space is formed between the rear wall 121 and the drive board 142 by the protrusion 221 coming into contact with the drive board 142 . Even in this case, the panel circuit 143 and light source circuit 144 are protected.

To summarize this modification and the embodiment described above, one of the case 91 and the cover 181 has a plurality of protrusions 221 that protrude toward the other. A hole is formed in the protrusion 221 into which a screw 223 for fixing the cover 181 to the case 91 is inserted. The protruding portion 221 contacts a portion of the component surface 161 where the panel circuit 143 and the light source circuit 144 are not mounted. According to this, when the protrusion 221 is provided on the cover 181, between the component surface 161 and the cover 181, and when the protrusion 221 is provided on the case 91, between the component surface 161 and the case 91, A space is formed. Therefore, even if the cover 181 is deformed due to a load being applied to the cover 181, the panel circuit 143 and the light source circuit 144 are unlikely to come into contact with the cover 181 or the case 91. This protects the panel circuit 143 and light source circuit 144. Therefore, the cover 181 protects the circuit mounted on the drive board 142. Further, as in (13) above, the space formed between the component surface 161 and the cover 181 is maintained by the protrusion 221 coming into contact with the periphery of the connector on the drive board 142. Therefore, the panel circuit 143 and the light source circuit 144 are protected.

- As shown in FIG. 15, the drive unit 141 may have two drive boards 142. In this modification, the drive unit 141 includes a drive board 142 on which a panel circuit 143 is mounted, and a drive board 142 on which a light source circuit 144 is implemented. That is, the drive unit 141 may have a configuration including two drive boards 142 on which the panel circuit 143 and the light source circuit 144 are individually mounted. In this case, the cover 181 is attached to the case 91 so as to cover the two drive boards 142.

- The opposing portion 182 may have a second opposing portion 199 that faces the input light source connector 165 and contacts the input light source connector 165.
- The opposing portion 182 may have a second opposing portion 199 that faces the output light source connector 166 and contacts the output light source connector 166.

- The panel connector 163 and the input light source connector 165 may be located on the same side of the drive board 142. The panel connector 163 and the output light source connector 166 may be located on the same side of the drive board 142.

- A hole may be formed in the case 91 through which the panel cable 171 passes. In this case, the panel cable 171 extends from the outside of the case 91 toward the inside of the case 91 by passing through this hole.

- The gaming machine 11 is not limited to a pachinko gaming machine, but may be a slot machine.
