Next, the light diffused by the light diffusing sheet member 143 enters the inner lens member 144 and is refracted or scattered by the dimple-shaped lens-shaped protrusion 144c of the inner surface side bottom portion 144b of the inner lens member 144. Thus, the light diffused by the light diffusion sheet member 143 is further diffused and emitted from the outer surface side bottom portion 144a of the inner lens member 144. Then, the diffused light sufficiently diffused by the light diffusing sheet member 143 and the inner lens member 144 emits decorative light of a predetermined color through the decorative lens member 145, and a signboard cover member from the player who is playing the game A predetermined character formed on the outer surface side bottom portion 134a of 130 is emitted and visually recognized.

  The illumination light emitted from the respective LEDs 111b disposed at the upper and lower ends of the electric decoration board 110 is incident on the outer lens member 141 and is a dimple-shaped lens having the inner surface side bottom 141b of the outer lens member 141. It is refracted or scattered by the protrusion 141c. Thus, the illumination light emitted from each LED 111b is diffused and emitted from the outer surface side bottom portion 141a of the outer lens member 141. The diffused light diffused by the outer lens member 141 is transmitted through a plurality of light transmission holes 132 formed in the peripheral portion of the decorative protrusion 131 (predetermined design) of the signboard lid member 130, and the game being played From a person, the peripheral portion of the predetermined design formed on the outer surface side bottom portion 134a of the signboard lid member 130 is emitted and visually recognized.

  An electric signboard 100 that is one of the electric decoration devices provided in each part of the center decoration 15 includes a light diffusion sheet member 143 that constitutes a light diffusion unit 140 between the sign cover member 130 and the electric decoration board 110. The inner lens member 144 and the outer lens member 141 are disposed, and the illumination light emitted from the LEDs 111a and 111b disposed on the illumination board 110 is diffused and emitted, so that the light diffusion sheet member 143 and the inner lens member 144 are emitted. In addition, the outer lens member 141 can efficiently diffuse the illumination light from the point-emitting type LED 111a and LED 111b having strong directivity, and the diffused light having a large light emitting area can be obtained. As a result, light can be emitted from the entire front surface of the electric signboard 100, and the decoration effect of the center decoration 15 among the various accessories provided on the game board 10 of the pachinko machine PM is further enhanced. It is intended to improve interest.

  Further, in the electric signboard 100, a light diffusion sheet member 143, an inner lens member 144, and an outer lens member 141 constituting the light diffusion unit 140 are disposed between the sign cover member 130 and the electric decoration board 110, and Since the illumination light emitted from the LEDs 111a and 111b disposed on the substrate 110 is diffused and emitted, the LED 111a and the LED 111b and the signboard cover member 130 cannot be provided with a sufficient distance. By arranging the light diffusion sheet member 143, the inner lens member 144 and the outer lens member 141 in layers, the illumination light from the LEDs 111a and 111b can be diffused efficiently, and the electric signboard 100 can be thinned. Can do.

  Since the outer lens member 141 has a lens-shaped protrusion 141c on the inner surface side bottom portion 141b, the light receiving area is larger than that in the case where the inner surface side bottom portion 141b is a flat surface, and the outer lens member 141 is generated inside the outer lens member 141. Increasing the factors of light refraction and scattering increases the diffuse transmitted light, thereby improving the light diffusion efficiency. Thereby, the illumination light irradiated from LED111b arrange | positioned at the electrical decoration board | substrate 110 is spread | diffused based on the property which the shape of the lens-shaped projection part 141c has. Further, since the inner lens member 144 has a lens-shaped protrusion 144c on the inner surface side bottom portion 144b, the light receiving area becomes larger than that in the case where the inner surface side bottom portion 144b is a flat surface, and the inner lens member 144 has an inner surface. As a result of an increase in the light refraction and scattering factors occurring in the light, the diffused transmitted light increases, and the light diffusion efficiency can be improved.

  As shown in FIGS. 7 and 8, the left and right ends of the fixing member 320 have contact portions 325 a and 326 a that protrude downward and extend to the right from the lower ends thereof (L in the rear view of the fixing device 300). The locking portions 325 and 326 are formed, and the signboard locking portions 214 and 224 formed on the link members 210 and 220 of the lifting device 200 and the locking portions 325 and 326 are respectively locked. The signboard locking portion 214 and the locking portion 325 are locked and the signboard locking portion 224 and the locking portion 326 are locked), and the electric signboard 100 is configured to be fixedly held at the standby position. Has been.

  According to the fixing device 300 configured as described above, the electric signboard 100 is fixedly held at the standby position, as shown in FIG. 9A, first, the electric motor M2 is driven to rotate by the protruding gear of the cam member 310. When the cam member 310 is rotated so that the protruding outer surface cam portion 313 of the cam member 310 and the pressing wall portion 324 of the fixing member 320 are in contact with each other via the portion 311, the tension of the cam member 310 is increased. The pressing wall portion 324 is pushed leftward by the outer surface cam portion 313, and the fixing member 320 is moved to the unlocking position. Then, in the state where the fixing member 320 is located at the unlock position, the electric signboard 100 is moved up by the lifting device 200 as described above. At this time, the contact portions 214a and 224a of the signboard locking portions 214 and 224 formed on the link members 210 and 220 of the lifting device 200 are brought into contact with the locking portions 325 and 326 formed on the fixing member 320, respectively. The electric signboard 100 is moved up to a predetermined position (hereinafter referred to as the uppermost position) above the portions 325a and 326a.

  Next, as shown in FIG. 9B, the rotation of the electric motor M2 in a state where the contact portions 214a and 224a of the signboard locking portions 214 and 224 formed on the link members 210 and 220 are located at the uppermost position. The drive is transmitted to the cam member 310 via the protruding gear portion 311 of the cam member 310 so that the circular outer surface cam portion 312 of the cam member 310 and the pressing wall portion 324 of the fixing member 320 are closely opposed to each other. By rotating, the pressing wall portion 324 that has been pushed to the left by the overhanging outer surface cam portion 313 of the cam member 310 is moved to the right by the elastic force of the spring member 323, and the fixing member 320 is moved to the locked position.

  Then, as shown in FIG. 9C, in the state where the fixing member 320 is located at the lock position, the end portion where the gear tooth portion 231 of the transmission arm member 230 of the lifting device 200 is formed via the transmission gear G. The electric motor M1 is rotationally driven (rotated in the downward direction) so as to move downward (the transmission arm member 230 rotates counterclockwise about the horizontal support shaft P3). When the transmission arm member 230 rotates counterclockwise about the horizontal support shaft P3, the engagement portion 232 of the transmission arm member 230 moves upward (the engagement portion 232 of the transmission arm member 230 and the link member 210). Therefore, the engaging portion 232 is moved by the weight of the link members 210 and 220 and the weight of the electric signboard 100 connected to the link members 210 and 220. With rotation, the base ends of the link members 210 and 220 (ends on which the gear tooth portions 211 and 221 are formed) rotate so as to move upward, and the distal ends of the link members 210 and 220 ( The end portions on which the signboard locking portions 214 and 224 are formed rotate so as to move downward.

  When the tip portions of the link members 210 and 220 are rotated so as to move downward, the lower surfaces of the contact portions 214a and 224a of the signboard locking portions 214 and 224 formed on the link members 210 and 220 and the fixing member 320, respectively. The locking members 325a and 326 formed on the abutting side portions 325a and 326a are in contact with the upper surfaces of the locking portions 325 and 326, respectively, and the rotation of the link members 210 and 220 in the direction in which the electric signboard 100 descends is restricted by the fixing member 320. Thus, the electric signboard 100 is fixedly held at the standby position.

  After the electric signboard 100 is fixedly held at the standby position, the transmission arm member 230 is arranged so that a predetermined interval is provided between the contact portions of the engagement portion 232 of the transmission arm member 230 and the engagement recess 212 of the link member 210. Is further rotated counterclockwise. As described above, even when the transmission arm member 230 is further rotated counterclockwise, the electric signboard 100 is locked by the fixing member 320 and held at the standby position, and the leading ends of the link members 210 and 220 are lowered. Therefore, only the transmission arm member 230 is rotated, and a predetermined portion is brought into contact with the engagement portion 232 of the transmission arm member 230 and the engagement concave portion 212 of the link member 210. This is a state in which an interval occurs (hereinafter referred to as a descent preparation completion state).

  The downward movement of the electric signboard 100 causes the rotation drive of the electric motor M2 to be transmitted to the cam member 310 via the protruding gear portion 311 of the cam member 310 in the state where the downward preparation is completed, and the overhanging outer surface cam portion 313 of the cam member 310 is transmitted. When the cam member 310 is rotated so that the pressing wall portion 324 of the fixing member 320 contacts the pressing wall portion 324, the pressing wall portion 324 is pushed leftward by the overhanging outer surface cam portion 313, and the fixing member 320 is moved to the unlocking position. Let When the fixing member 320 moves to the unlocking position, the locking state between the sign locking portions 214 and 224 of the link members 210 and 220 and the locking portions 325 and 326 of the fixing member 320 is released, and the link members 210 and 220 are respectively released. And the weight of the electric signboard 100 connected to the link members 210 and 220 cause the leading end portions of the link members 210 and 220 to rotate downward and the electric signboard 100 to move downward. At this time, the overhang portions 136a and 136a (see FIG. 3) of the guide portion 136 of the sign cover member 130 are inserted into the guide grooves 241 and 241 (see FIG. 7) of the guide rail members 240 and 240 and slide downward. The electric signboard 100 moves downward along the guide rail members 240 and 240.

  When the electric signboard 100 moves downward, the buffer member 250 provided in the plane in which the link members 210 and 220 are rotated is sandwiched from the left and right directions by the protruding portions 215 and 225 of the link members 210 and 220. When the protrusions 215 and 225 and the buffer member 250 come into contact with each other, the rotation of the link members 210 and 220 in the direction in which the electric signboard 100 moves downward is stopped, and the electric signboard 100 is positioned at the exposed position.

  Thus, when the electric signboard 100 to which the appropriate kinetic energy is given by free fall stops, the projecting portions 215 and 225 of the link members 210 and 220 come into contact with the buffer member 250 so as to sandwich the buffer member 250. 250 effectively relieves an impact generated when the electric signboard 100 stops (absorbs the kinetic energy of the electric signboard 100 efficiently), so that vibration (vibration) at the time of stoppage can be reduced. The electric signboard 100 can be smoothly positioned at the exposed position. Moreover, since the shock absorbing member 250 can effectively relieve the impact caused by the contact of the link members 210 and 220 with the shock absorbing member 250, the durability of the link members 210 and 220 can be improved. The electric signboard 100 can be smoothly stopped at the exposed position. Furthermore, since the electric signboard 100 moves downward along the guide rail members 240 and 240, the movement of the electric signboard 100 in directions other than the directions of the guide rail members 240 and 240 is restricted, and the electric signboard 100 is moved downward smoothly. And can be smoothly stopped at the exposure position.

  Next, the vibration which makes the decoration member 22a (refer FIG. 2) provided in the front surface of the upper electrical decoration apparatus 22 attached above the center decoration 15 reciprocate left and right according to the progress of the game (vibrates). The apparatus 400 will be described with reference to FIGS. FIG. 10 shows a schematic configuration diagram of the vibration device 400 as viewed from the rear side, and FIG. 11 shows a case where the decorative plate member 22a reciprocates left and right by the vibration device 400. In FIG. 10, portions where the link members 210 and 220 and the transmission arm member 230 overlap are illustrated by a two-dot chain line.

A reciprocating arm member 410 that supports the decorative member 22a of the upper electric decoration device 22, and a support member 420 that engages with the reciprocating arm member 410 and reciprocates left and right. The vibration device 400 is configured by sharing the electric motor M2 and the cam member 310 that constitute the fixing device 300.

  In the state shown in FIG. 10, the reciprocating arm member 410 has a dogleg-shaped plate shape and is formed using a resin material such as plastic. The reciprocating arm member 410 is pivotally supported in the front-rear direction by the mounting frame member F (provided on the back surface of the center ornament 15 as described above but not shown) by the horizontal support shaft P5, and rotates around the horizontal support shaft P5. It is configured to move freely. An engaging groove portion 411 having an opening in the front-rear direction is formed at the upper end portion of the reciprocating arm member 410, and the engaging groove portion 411 and the engaging portion 422 of the support member 420 are engaged with each other so that the reciprocating arm is engaged. The member 410 and the support member 420 are configured to be interlocked.

  A cylindrical engagement portion 412 is formed to protrude forward at a substantially central portion (a dogleg-shaped bent portion) on the rear surface of the reciprocating arm member 410, and this engagement portion 412 is formed on the cam member 310. It is slidably inserted into a groove cam (see FIG. 8) constituted by a circular groove cam portion 314 and an overhang groove cam portion 315 formed on the rear surface. When the cam member 310 rotates, the engaging portion 412 of the reciprocating arm member 410 slides inside the groove cam, and the engagement of the reciprocating arm member 410 depends on the shape of the circular groove cam portion 314 and the extended groove cam portion 315. The joining portion 412 and the engaging groove portion 411 are configured to rotate (reciprocate) in the left-right direction. Since the engaging portion 412 is formed closer to the horizontal support shaft P5 (rotation center) than the engaging groove portion 411, the engaging groove portion 411 is larger than the reciprocating movement of the engaging portion 412. It is configured to reciprocate in the left-right direction.

  The support member 420 has a substantially rectangular cylindrical shape and is formed using a transparent resin material such as ABS resin or polycarbonate (PC). The support member 420 is pivotally supported in the left-right direction on the rear surface of the upper illumination device 22 (see FIG. 2) by the horizontal support shaft P6, and the support member 420 is configured to be slidable in the left-right direction along the horizontal support shaft P6. ing.

The cam member 310 is rotated by being transmitted to the cam member 310 via the gear portion 311, and the engaging portion 412 of the reciprocating arm member 410 is moved into the groove cam of the cam member 310 (circular groove cam portion 314, overhang groove cam portion 315). Slide inside. As shown in FIG. 11A, the insertion position of the engaging portion 412 of the reciprocating arm member 410 inserted into the circular groove cam portion 314 of the cam member 310 is changed from the circular groove cam portion 314 to the overhang groove cam portion 315. When the cam member 310 rotates in the direction (the direction of arrow a in the figure), the reciprocating arm member 410 is moved so that the engaging portion 412 of the reciprocating arm member 410 moves rightward depending on the shape of the groove cam of the cam member 310. Rotates clockwise around the horizontal support shaft P5. That is, since the engaging groove 411 of the reciprocating arm 410 rotates so as to move to the right, the inner part of the engaging groove 411 and the engaging part 422 of the support member 420 come into contact with each other, and the reciprocating arm member 410. With the rotation, the support member 420 moves rightward (in the direction of arrow c in the figure) along the horizontal support shaft P6.

  11B, the insertion position of the engaging portion 412 of the reciprocating arm member 410 inserted into the overhang groove cam portion 315 of the cam member 310 is changed from the overhang groove cam portion 315 to the circular groove cam. When the cam member 310 rotates in the direction of the portion 314 (the direction of the arrow b in the drawing), the engagement portion 412 of the reciprocating arm member 410 reciprocates to the left depending on the shape of the groove cam of the cam member 310. The arm member 410 rotates counterclockwise about the horizontal support shaft P5. That is, since the engaging groove 411 of the reciprocating arm 410 is rotated so as to move to the left, the inner portion of the engaging groove 411 and the engaging portion 422 of the support member 420 come into contact with each other. With this rotation, the support member 420 moves leftward (in the direction of arrow d in the figure) along the horizontal support shaft P6. Thus, the insertion position of the engaging portion 412 of the reciprocating arm member 410 is in the direction from the circular groove cam portion 314 to the extended groove cam portion 315 or the direction from the extended groove cam portion 315 to the circular groove cam portion 314. Then, the cam member 310 is rotated by the electric motor M2, and the decorative member 22a of the upper electric decoration device 22 attached to the support member 420 is reciprocated (vibrated) in the left-right direction.

  According to the present embodiment described above, the cam member 310 is rotated to slide the engaging portion 412 of the reciprocating arm member 410 inside the groove cam (circular groove cam portion 314, overhang groove cam portion 315) of the cam member 310. The engaging portion 412 and the engaging groove portion 411 of the reciprocating arm member 410 are rotated so as to move in the left-right direction, so that the inner portion of the engaging groove portion 411 and the engaging portion 422 of the support member 420 are in contact with each other. In contact, the support member 420 moves in the left-right direction along the horizontal support shaft P6, and the decorative member 22a provided on the front surface of the upper electrical decoration member 22 reciprocates (vibrates) in the left-right direction. Therefore, by controlling the rotation of the cam member 310 by the electric motor M2, it is possible to cause the decorative member 22a to freely vibrate in accordance with the game effect, such as changing the vibration speed, thereby improving the visual effect. Can increase the interest of the game.

  Further, in the reciprocating arm member 410, the engaging portion 412 is formed at a position closer to the horizontal support shaft P5 (rotation center) than the engaging groove portion 411. Thus, the engaging groove portion 411 moves more in the left-right direction. That is, a large vibration can be generated in the decorative member 22a by a small rotation of the cam member 310 (groove cam), and the visual effect can be improved to further increase the interest of the game.
