In the present embodiment, the number of symbols that move with the rotation of the reel within the specified time is referred to as the “number of sliding pieces”. When the prescribed period is 190 msec, the maximum number of sliding pieces is determined to be four symbols, and when the prescribed period is 75 msec, the maximum number of sliding pieces is determined to be one symbol.

  When the internal winning combination that permits the display of the combination of the symbols related to the winning is determined, the reel stop control unit normally changes the combination of the symbols within a specified time of 190 msec (for four frames of the symbol) to the winning determination line. The rotation of the reel is stopped so as to be displayed along as much as possible. In addition, for example, during the operation of a challenge bonus (CB), which is a second type special accessory, and a middle bonus (MB) for continuously operating the CB, the reel stop control means controls one or more reels. The rotation of the reel is stopped so that the combination of the symbols is displayed as much as possible along the winning determination line within the time 75 msec (for one frame of the symbol). Further, the reel stop control means uses various specified times corresponding to the game state to rotate the reels so that a combination of symbols whose display is not permitted by the internal winning combination is not displayed along the winning determination line. Stop.

  When the rotations of the plurality of reels are all stopped in this way, the winning determination unit determines whether or not the combination of the symbols displayed along the winning determination line is a winning combination. This winning determination means is carried out by a main control circuit described later. When the prize determining means determines that the prize is related to a prize, a bonus such as a medal payout is given to the player. In the pachislot, the above-described series of flows is performed as one game.

Various effects are performed.

  When the start lever is operated, an effect random number value (hereinafter, effect random number value) is extracted separately from the random number value used for determining the internal winning combination described above. When the effect random number value is extracted, the effect content determination means determines, by lottery, the effect content to be executed this time from a plurality of types of effect contents associated with the internal winning combination. This effect content determining means is carried by a sub-control circuit described later.

  When the effect contents are determined, the effect execution means is linked with each opportunity such as when the rotation of the reels is started, when the rotation of each reel is stopped, or when the determination of the presence or absence of a prize is performed. To proceed with the production. This effect executing means is carried by a sub-control circuit described later. As described above, in the pachislot, by executing the effect contents associated with the internal winning combination, the player has an opportunity to know or predict the determined internal winning combination (in other words, a combination of symbols to be aimed). Provided to improve the interest of the player.

  A circular through hole 141a is formed in the center of the bottom 141. The diameter of the through hole 141a is set smaller than the diameter of the second gear 133. The inner peripheral surface 141b of the bottom 141 that forms the through hole 141a is a specific example of the inner wall surface of the case according to the present invention. The plurality of rolling elements 116A come into contact with the inner peripheral surface 141b. In addition, a plurality of rolling elements 116B come into contact with a surface of the bottom 141 facing the rotating member 113.

  As shown in FIG. 8, three mounting bosses 145 are provided on the outer peripheral surface of the side wall portion 142. The mounting boss 145 is formed in a substantially cylindrical shape extending in the axial direction of the side wall portion 142, and has a female screw portion inside. These three mounting bosses 145 are fixed to the three case fixing portions 123b of the mounting bracket 111 using screws (not shown).

  When the case 112 is fixed to the mounting bracket 111, the center of the through hole 141 a in the case 112 coincides with the axis of the second gear 133 and the axis of the side peripheral portion 122 of the mounting bracket 111.

  Note that the fixing of the case 112 to the mounting bracket 111 is not limited to using screws, and other fixing methods such as fixing using an adhesive, caulking fixing, and fitting fixing may be adopted. it can.

  The flange portion 143 is continuous with the other end of the side wall portion 142 in the axial direction. The flange portion 143 protrudes radially outward of the side wall portion 142, and has an elliptical outer contour. The case cover 114 is joined to the flange portion 143.

[Rotating member]
The rotating member 113 is formed in a hollow cylindrical shape, and has a front surface 151 serving as a presentation surface, a back surface 152, and a side surface 153. The outer diameter of the rotating member 113 is set smaller than the inner diameter of the side wall 142 of the case 112. The rotating member 113 is rotatably accommodated in the case 112.

  At the center of the surface 151 of the rotating member 113, a triangular light transmitting portion 155 is provided. The light transmitting portion 155 is formed of a transparent or translucent member that transmits light, and transmits light.

  As shown in FIG. 8, a circular through hole 152a is formed in the center of the back surface 152 of the rotating member 113. The through-hole 152a faces the light transmitting portion 155 on the front surface 151. The through hole 152a faces the through hole 141a of the case 112 and the opening 133a of the second gear 133. Thereby, the light transmitting portion 155 of the rotating member 113 faces the plurality of LEDs 126.

  Further, on the back surface 152, an inner cylinder 156, an outer cylinder 157, and three rolling element housing portions 158 are provided. The inner cylinder 156 is formed in a cylindrical shape surrounding the periphery of the through hole 152a. The outer diameter of the inner cylinder 156 is smaller than the diameter of the through hole 141a in the case 112. The inner cylinder 156 is inserted into the opening 133a (see FIG. 7) of the second gear 133 through the through hole 141a in the case 112, and is fitted with the second gear 133.

  The outer cylinder 157 is formed in a cylindrical shape surrounding the inner cylinder 156. The outer diameter of the outer cylinder 157 is smaller than the diameter of the through hole 141a in the case 112. Thereby, the outer cylinder 157 passes through the through hole 141a in the case 112. The height of the outer cylinder 157 projecting from the back surface 152 is lower than the height of the inner cylinder 156 projecting from the back surface 152. Therefore, the outer cylinder 157 does not interfere with the second gear 133.

  The outer peripheral surface of the outer cylinder 157 is a specific example of the side peripheral surface of the rotating member according to the present invention. On the outer peripheral surface of the outer cylinder 157, three rolling element housing recesses 157a are provided. The three rolling element housing recesses 157a are arranged at equal intervals along the circumferential direction of the outer cylinder 157, and each of the three rolling element housing recesses 157a rotatably houses a spherical rolling element 116A.

  The radial depth (length) of the outer cylinder 157 in the rolling element housing recess 157a is smaller (shorter) than the diameter of the rolling element 116A. Therefore, the rolling element 116A accommodated in the rolling element accommodating recess 157a protrudes from the outer peripheral surface of the outer cylinder 157 in the radial direction of the outer cylinder 157, and comes into contact with the inner peripheral surface 141b of the case 112 (see FIG. 9).

  Three mounting bosses 159 are provided between the inner cylinder 156 and the outer cylinder 157. The mounting boss 159 is formed in a substantially cylindrical shape projecting perpendicularly from the back surface 152, and has a female screw portion inside. These three mounting bosses 159 are fixed to the three rotating member fixing portions 133b of the second gear 133 using screws 130 (see FIG. 9). Thus, the rotating member 113 is fixed to the second gear 133 and rotates together with the second gear 133.

  When the rotating member 113 is fixed to the second gear 133, the axis of the rotating member 113 coincides with the axis of the second gear 133 and the axis of the side peripheral portion 122 of the mounting bracket 111. Therefore, in a state where the rotary decorative portion 22 is attached to the decorative frame 101 (see FIG. 2), the axial direction (axial line) of the rotating member 113 is inclined with respect to a plane perpendicular to the vertical direction, and Are inclined such that the surface 151 faces obliquely downward.

  The fixing of the rotating member 113 to the second gear 133 is not limited to using screws, and other fixing methods such as fixing using an adhesive, caulking fixing, and fitting fixing are adopted. be able to.

  The three rolling element housing portions 158 are provided at the outer edge of the back surface 152. In addition, they are arranged so as to be arranged at equal intervals along the circumferential direction of the back surface 152. Each of the rolling element housing portions 158 is formed in a rectangular frame shape protruding from the back surface 152, and rotatably stores the spherical rolling element 116B.

  The length of the rolling element housing portion 158 protruding from the back surface 152 is shorter than the diameter of the rolling element 116B. Therefore, the rolling element 116B accommodated in the rolling element accommodating portion 158 protrudes from the upper end surface of the rolling element accommodating portion 158, and comes into contact with the bottom 141 of the case 112 (see FIG. 9).

[Case cover]
The case cover 114 is formed in a dome shape using a transparent member such as an acrylic plate or a translucent member. The contour of the edge 114 a of the case cover 114 is formed in an elliptical shape substantially equal to the contour of the outer periphery of the flange 143 of the case 112.

  The edge 114 a of the case cover 114 is joined to the flange 143 of the case 112. Thereby, the case cover 114 covers the surface 151 of the rotating member 113 accommodated in the case 112. The player can visually recognize the surface 151 of the rotating member 113 via the case cover 114.

<Operation of rotating decoration part>
Next, the operation of the rotary decoration unit 22 will be described with reference to FIG.
In the present embodiment, when performing a specific effect, the rotating decoration portion 22 is caused to emit light and to perform a rotating operation.

  When it is determined that a specific effect is to be performed, the sub CPU 81 and the rotation decoration unit driving circuit 95 (see FIG. 5) drive the rotation decoration unit 22 according to the rotation decoration unit driving data. That is, the LED 126 emits light and the motor 131 is driven.

  The light emitted from the LED 126 passes through the opening 133a of the second gear 133, the inner tube 156 of the rotating member 113, and the through hole 152a, and passes through the light transmitting portion 155 (see FIG. 9). Thereby, to the player, it looks as if the light transmitting portion 155 of the rotary decoration portion 22 emits light.

  When the motor 131 is driven, a rotation shaft (not shown) of the motor 131 and a first gear 132 fixed to the rotation shaft rotate. Then, the rotation of the first gear 132 is transmitted to the second gear 133 while being decelerated. Thereby, the rotating member 113 fixed to the second gear 133 rotates.

  The rotating member 113 is rotatably accommodated in the case 112 via a plurality of rolling elements 116A and 116B. Accordingly, the weight of the rotating member 113 is distributed and added to the rotating mechanism 115 and the case 112, and the load on the rotating mechanism 115 can be reduced. As a result, it is possible to prevent the rotation mechanism 115 from being damaged or broken.

  A plurality of rolling elements 116A and 116B are interposed between the rotating member 113 and the case 112. Thus, when the rotating member 113 rotates with respect to the case 112, the three rolling elements 116A rotate while contacting the outer peripheral surface of the outer cylinder 157 of the rotating member 113 and the inner peripheral surface 141b of the case 112. Further, the three rolling elements 116 </ b> B rotate while contacting the back surface 152 of the rotating member 113 and the bottom 141 of the case 112.

  Therefore, the resistance to rotation of the rotating member 113 can be reduced as compared with the case where the rotating member 113 and the case 112 are directly contacted. As a result, the load on the rotation mechanism 115 can be further reduced.

  Further, the outer peripheral surface of the outer cylinder 157 of the rotating member 113 and the inner peripheral surface 141b of the case 112 face each other in the radial direction of the rotating member 113 and sandwich the rolling element 116A. On the other hand, the back surface 152 of the rotating member 113 and the bottom 141 of the case 112 face each other in the radial direction of the rotating member 113 and sandwich the rolling element 116B. Thereby, the posture of the rotating member 113 can be stabilized in the radial direction and the axial direction of the rotating member 113.

  In the present embodiment, since the surface 151 of the rotating member 113 provided with the light transmitting portion 155 faces obliquely downward, the light transmitting portion 155 can be directed to the player. As a result, it is possible to make the light emission and the rotation operation of the rotary decoration portion 22 easily visible to the player.

  Further, in the present embodiment, a through hole 141a is formed in bottom 141 of case 112, and second gear 133 of rotating mechanism 115 is fixed to rotating member 113 via through hole 141a. Thereby, the axis of the rotating member 113 and the axis of the second gear 133 can be matched.

  Further, in the present embodiment, the rotary decorative portion 22 is provided with the mounting bracket 111. A board 125 on which the LED 126 is mounted is fixed to the mounting bracket 111. An opening 133 a is formed in a central portion including the axis of the second gear 133, and the LED 126 faces the light transmitting portion 155 of the rotating member 113 via the opening 133 a of the second gear 133. .

  Thereby, it can be seen that the light transmitting portion 155 of the rotating member 113 emits light. Further, the light emitted from the LED 126 can be applied to the light transmitting portion 155 at the center of the surface 151 of the rotating member 113. Further, since the substrate 125 and the LED 126 are not rotated together with the rotating member 113, the load on the first and second gears 132 and 133 and the motor 131 can be reduced even when the rotating member 113 emits light.

  In the present embodiment, the LED 126 is used as a specific example of the light emitting unit. However, the light emitting unit according to the present invention is not limited to an LED (Light Emitting Diode), and for example, an incandescent light bulb or a fluorescent lamp may be used.

Further, in the present embodiment, rolling element 116A is interposed between the outer peripheral surface of outer cylinder 157 of rotating member 113 and the inner peripheral surface 141b of case 112. The outer peripheral surface of the outer cylinder 157 of the rotating member 113 indicates the side peripheral surface of the rotating member according to the present invention, and the inner peripheral surface 141b of the case 112 indicates the inner wall surface of the case according to the present invention.
However, the side peripheral surface of the rotating member according to the present invention may be, for example, the side surface 153 of the rotating member 113. In this case, the rolling element is interposed between the side surface 153 of the rotating member 113 and the inner surface of the side wall 142 of the case 112.

<Cooling structure of closed space>
Next, a closed space formed in the front door 2b and a cooling structure of the closed space will be described with reference to FIGS.
FIG. 10 is a rear view of the front panel 10 provided on the front door 2b. FIG. 11 is a longitudinal sectional view of the front door 2b.

  As shown in FIG. 10, the decorative frame 101 is formed in a substantially rectangular frame shape having an opening 101a, and includes an upper frame portion 105, a lower frame portion 106, and a left frame portion (left side as viewed from the back side). 107 and a right frame (right side as viewed from the back side) 108. The movable decorative portion 23 described above is attached to a central portion on the back surface of the upper frame portion 105. A blower 201 is attached to a corner formed by the upper frame 105 and the right frame 108 on the back surface of the decorative frame 101.

The movable decorative part 23 and the blower 201 face the back surface of the decorative frame 101. Therefore, when the decorative frame 101 is viewed from the front side, the movable decorative portion 23 and the blower 201 are hidden by the decorative frame 101, and the player cannot visually recognize the movable decorative portion 23 and the blower 201 from the opening 101a.
The movable decorative portion 23 is exposed to the opening 101a by rotating with respect to the decorative frame 101. The configuration and operation of the movable decorative portion 23 will be described later in detail.

  As shown in FIG. 11, in the present embodiment, a closed space 200 is formed by the liquid crystal display device 11, the decorative frame 101, and the protective cover 102. The movable decorative part 23 (not shown) and the blower 201 are arranged above the closed space 200.

  The closed space 200 is not a completely closed space. For example, a minute gap is formed between the decorative frame 101 and the protective cover 102 or between the decorative frame 101 and the liquid crystal display device 11. . Therefore, the closed space 200 communicates with the external space through the minute gap as described above.

  The blower 201 is, for example, a sirocco fan, and blows air in the closed space 200 to lower the temperature in the closed space 200. This blower 201 is formed in a disk shape having an appropriate thickness. An intake port 201a is formed on one plane of the blower 201, and an exhaust port 201b is formed on a side peripheral surface.

  The blower 201 is arranged so that the intake port 201a faces the side opposite to the liquid crystal display device 11 (the back side of the decorative frame 101). An appropriate gap is provided between one flat surface of the blower 201 and the back surface of the decorative frame 101. The blower 201 is arranged such that the exhaust port 201b faces the left frame 107 of the decorative frame 101.

  The air discharged from the exhaust port 201b of the blower 201 travels in the horizontal direction along the display unit 11a. Thereby, the air heated by the display unit 11a of the liquid crystal display device 11 can flow efficiently. In addition, the warm air that has risen due to the convection in the closed space 200 can be caused to flow by the air that the blower 201 has discharged. Thereby, it is possible to prevent warm air from accumulating in the upper part of the closed space 200.

  The closed space 200 is not a completely closed space but communicates with an external space. Therefore, the flow of the air in the closed space 200 can promote the flow of air generated between the closed space 200 and the external space. As a result, heat can be prevented from accumulating in the closed space 200, and the temperature in the closed space 200 can be reduced.

It is preferable that the blower according to the present invention be arranged above the closed space 200. Thereby, warm air that has risen due to convection in the closed space 200 can flow.
The blower according to the present invention may be arranged at a lower portion of the closed space 200 or at an intermediate portion of the closed space 200 in the vertical direction. Also in this case, the air in the closed space 200 can flow, and the temperature in the closed space 200 can be reduced.

  The air discharged from the exhaust port of the blower according to the present invention preferably travels along the display 11a. Thereby, the air heated by the display unit 11a of the liquid crystal display device 11 can flow efficiently. Further, it is preferable that the air discharged from the exhaust port of the blower according to the present invention travels in the horizontal direction along the display section 11a. Thereby, the air in the closed space 200 can be stirred, and the temperature in the closed space 200 can be reduced.

  Note that the blower according to the present invention may be arranged such that air discharged from the exhaust port travels in the vertical direction along the display unit 11a. Also in this case, the air heated by the display unit 11a of the liquid crystal display device 11 can flow efficiently.

[Configuration of right movable unit]
Next, the configuration of the right movable unit 303 will be described with reference to FIG.

  As shown in FIG. 13, the right movable unit 303 has the same configuration as the left movable unit 302, and is formed symmetrically with the left movable unit 302. That is, the right movable unit 303 includes the first member 451, the second member 452, and the third member 453 stacked in the front-rear direction Y.

  A connection member 471 having a gear piece 473 is attached to the first member 451. The connecting member 471 is provided with a locking pin 475. The gear piece 473 is formed with a tooth 476 that meshes with the tooth 376 of the left movable unit 302. Further, the first member 451 is provided with a rotation shaft (not shown) that is rotatably fitted into a fitting hole of the unit connection portion 322 in the base portion 301.

Further, the third member 453 is urged in a first rotation direction R1 (see FIG. 15) by a torsion coil spring (not shown).

<Lock of movable decoration part>
Next, the lock of the movable decorative portion 23 will be described with reference to FIG.
FIG. 15 is an explanatory diagram illustrating a state in which the left and right movable units 302 and 303 of the movable decoration unit 23 are arranged at the standby position.

  The left and right movable units 302 and 303 of the movable decorative portion 23 are normally arranged at standby positions (first positions) hidden behind the upper frame portion 105 of the decorative frame 101. Then, it operates when a special effect is performed, and is arranged at an exposure position (second position) exposed to the opening 101a of the decorative frame 101.

  As shown in FIG. 15, the left movable unit 302 arranged at the standby position is stopped in a state where the arc portion 361 of the first member 351 is convex upward. Further, the right movable unit 303 is arranged symmetrically with the left movable unit 302, and stops in a state where the arc portion 461 of the first member 451 becomes convex upward.

  The state of the right movable unit 303 is bilaterally symmetric with the state of the left movable unit 302. Therefore, the state of the left movable unit 302 will be described below, and the description of the state of the right movable unit 303 will be omitted.

  In a state where the left movable unit 302 is located at the standby position, the locking pin 375 of the first member 351 is engaged with one end of the rotation restricting groove 386 of the second member 352. Thus, the second member 352 does not rotate with respect to the first member 351 due to its own weight. The arc portion 381 of the second member 352 overlaps the arc portion 361 of the first member 351 when viewed from the front-back direction Y.

  In a state where the left movable unit 302 is located at the standby position, the engagement pin 396 of the third member 353 is engaged with one end of the engagement groove 384 of the second member 352. The third member 353 is urged in the second rotation direction R2 by the torsion coil spring 400 (see FIG. 14). Accordingly, the third member 353 does not rotate with respect to the first member 351 due to its own weight.

  In a state where the left movable unit 302 is located at the standby position, the engaging pin 378 provided on the gear piece 373 of the first member 351 is engaged with the second cam groove 342 of the slider 333. The guide pins 334 and 335 attached to the base portion 301 are engaged with one ends of the engagement grooves 343 and 344 of the slider 333, respectively.

  Hereinafter, a direction from one end of the engagement groove 343 to the other end of the engagement groove 343 is defined as a right direction X1, and a direction from the other end of the engagement groove 343 to one end of the engagement groove 343 is defined as a left direction X2. The right direction X1 indicates one of the first directions according to the present invention, and the left direction X2 indicates the other of the first directions according to the present invention.

  As described above, since the guide pins 334 and 335 are engaged with one ends of the engagement grooves 343 and 344, the movement of the slider 333 in the right direction X1 is locked. As a result, the engagement pin 378 of the first member 351 is not pressed in the right direction X1 by the slider 333, and the rotation of the first member 351 (the left movable unit 302) in the second rotation direction R2 is prevented. Has been blocked.

In a state where the left movable unit 302 is located at the standby position, the engagement pin 339 of the crank 332 is engaged with one end (upper end) of the first cam groove 341 of the slider 333. Thus, the rotation of the crank 332 in the first rotation direction R1 is limited.
The axis of the engagement pin 339 is parallel to the left-right direction X and is higher than the position on the plane including the axis (the rotation center of the crank 332) of the rotation shaft 331a of the motor 331 (the first axis). (A position displaced in the rotation direction R1).

  Thus, when the slider 333 presses the engagement pin 339 in the left direction X2, the crank 332 attempts to rotate in the first rotation direction R1. However, since the first cam groove 341 of the slider 333 restricts the movement of the engagement pin 339 in the first rotation direction R1, the crank 332 moves in the first rotation direction R1 and the second rotation direction R2. Does not rotate.

  Therefore, the movement of the slider 333 in the left direction X2 is restricted. As a result, the engagement pin 378 of the first member 351 is not pressed in the left direction X2 by the slider 333, and the rotation of the first member 351 (the left movable unit 302) in the first rotation direction R1 is prevented. Has been blocked.

  Since the teeth 476 of the right movable unit 303 mesh with the teeth 376 of the left movable unit 302, the right movable unit 303 does not rotate unless the left movable unit 302 rotates.

  Thus, according to the present embodiment, if the left and right movable units 302 and 303 are arranged at the standby position, the rotation of the left and right movable units 302 and 303 can be locked. Thus, even if vibration or impact is applied to the pachislot 1, the left and right movable units 302 and 303 of the movable decorative portion 23 can be prevented from contacting other members constituting the pachislot 1.

  The lock of the left and right movable units 302 and 303 is released by driving the motor 331 (see FIG. 13) of the drive mechanism 304 to rotate the rotation shaft 331a of the motor 331 in the second rotation direction R2.

In the present embodiment, when the left movable unit 302 is located at the standby position, the axis of the engagement pin 339 is parallel to the left-right direction X and is on a plane including the axis of the rotation shaft 331a. It was configured to be arranged above the position.
However, the axis of the engagement pin 339 may be arranged on a plane including the axis of the rotation shaft 331a of the motor 331 (the rotation center of the crank 332). In this case, even if the slider 333 presses the engagement pin 339 in the left direction X2, the crank 332 does not rotate in the first rotation direction R1 and the second rotation direction R2.

  Therefore, the movement of the slider 333 in the left direction X2 is restricted, and the engagement pin 378 of the first member 351 is not pressed by the slider 333 in the left direction X2. As a result, the rotation of the first member 351 (the left movable unit 302) in the first rotation direction R1 is prevented.

<Operation of movable decoration part>
Next, the operation of the movable decorative portion 23 will be described with reference to FIGS.
FIG. 16 is an explanatory diagram illustrating a state in which the left and right movable units 302 and 303 of the movable decoration unit 23 have rotated from the state illustrated in FIG. 15. FIG. 17 is an explanatory diagram illustrating a state in which the second and third members of the left and right movable units 302 and 303 of the movable decoration unit 23 have moved relative to the first member from the state illustrated in FIG. 16. FIG. 18 is an explanatory view showing a state in which the left and right movable units 302 and 303 of the movable decorative part 23 are further operated from the state shown in FIG. FIG. 19 is a front view of the front panel 10 when the left and right movable units 302 and 303 of the movable decorative portion 23 are arranged at the exposed positions.

  When moving the left and right movable units 302 and 303 from the standby position shown in FIG. 15 to the exposure position shown in FIG. 18, the motor 331 (see FIG. 13) of the drive mechanism 304 is driven to rotate the rotation shaft 331a of the motor 331. Rotate in the second rotation direction R2.

  As a result, the crank 332 rotates in the second rotation direction R2, and the engagement pin 339 of the crank 332 engages with the first cam groove 341 of the slider 333, and the second rotation direction about the rotation shaft 331a. Displace to R2. As a result, as shown in FIG. 16, the slider 333 is guided by the guide pins 334 and 335 and moves in the left direction X2 by the distance the engagement pin 339 has moved in the left direction X2.

  The slider 333 moving in the left direction X2 presses the engagement pin 378 in the left direction X2. Thus, the engagement pin 378 is displaced in the first rotation direction R1 around the rotation axis (coaxial with the connection shaft 377) of the first member 351 while engaging with the second cam groove 342 of the slider 333. .

  As a result, the first member 351 provided with the engagement pin 378 and the second and third members 352 and 353 connected to the first member 351 rotate in the first rotation direction R1 about the rotation axis. . At this time, the second and third members 352 and 353 do not move with respect to the first member 351. In other words, the left movable unit 302 rotates in the first rotation direction R1 about the rotation shaft disposed at the standby position.

  The gear piece 373 of the left movable unit 302 meshes with the gear piece 473 of the right movable unit 303. Therefore, when the left movable unit 302 rotates in the first rotation direction R1 about the rotation axis (coaxial with the connection axis 377), the right movable unit 303 rotates about the rotation axis (coaxial with the connection axis 477). It turns in the second rotation direction R2. Accordingly, the left movable unit 302 and the right movable unit 303 rotate so as to approach each other from the standby position.

  When the left movable unit 302 rotates in the first rotation direction R1, the linear portion 382 of the second member 352 in the left movable unit 302 comes into contact with the contact portion 306. Thus, the rotation of the second member 352 in the first rotation direction R1 is stopped. Similarly, when the right movable unit 303 rotates in the second rotation direction R2, the linear portion 482 of the second member 452 of the right movable unit 303 comes into contact with the contact portion 306. Thus, the rotation of the second member 452 in the second rotation direction R2 is stopped.

  When the crank 332 further rotates in the second rotation direction R2 from the state shown in FIG. 16, the slider 333 further moves to the left direction X2. As a result, as shown in FIG. 17, the engagement pin 378 is pressed in the left direction X2 by the slider 333, and the first member 351 is rotated in the first rotation direction R1 around the rotation shaft (coaxial with the connection shaft 377). To rotate.

  At this time, the second member 352 does not rotate together with the first member 351 because the linear portion 382 is in contact with the contact portion 306. Accordingly, the second member 352 rotates around the connection shaft 377 with respect to the first member 351. That is, the first member 351 and the second member 352 move relatively. As a result, the arc portion 381 of the second member 352 does not overlap the arc portion 361 of the first member 351 when viewed from the front-rear direction Y, and when the front panel 10 (see FIG. 19) is viewed from the front, the second member 352 is formed. Are exposed.

  When the first member 351 and the second member 352 relatively move, the engagement pin 396 of the third member 353 moves from one end to the other end of the engagement groove 384 of the second member 352. As a result, the third member main body 391 and the engagement assisting portion 392 rotate in the first rotation direction R1 about the rotation shaft 394 with respect to the first member 351. That is, the first member 351 and the third member 353 move relatively. The third member main body 391 and the engagement assisting portion 392 rotate in the first rotation direction R1 against the urging force in the second rotation direction R2 by the torsion coil spring 400 (see FIG. 14). .

  On the other hand, when the first member 351 of the left movable unit 302 rotates in the first rotation direction R1 from the state shown in FIG. 16, the first member 451 of the right movable unit 303 moves from the state shown in FIG. It rotates in the rotation direction R2 (see FIG. 17). At this time, the second member 452 does not rotate with the first member 451, but rotates about the connection shaft 477 with respect to the first member 451. That is, the first member 451 and the second member 452 move relatively.

  Then, the first member 451 and the second member 352 relatively move, so that the third member main body 491 and the engagement assisting portion 492 move to the first member 451 around the rotation shaft portion 494. 2 in the rotation direction R2. That is, the first member 451 and the third member 453 move relatively.

  When the crank 332 further rotates in the second rotation direction R2 from the state shown in FIG. 17, the slider 333 further moves to the left direction X2. As a result, as shown in FIG. 18, the engagement pin 378 is pressed in the left direction X2 by the slider 333, and the first member 351 is rotated in the first rotation direction R1 around the rotation shaft (coaxial with the connection shaft 377). To rotate.

  Thus, the second member 352 in contact with the contact portion 306 rotates around the connection shaft 377 with respect to the first member 351. Then, the locking pin 375 of the first member 351 is engaged with the other end of the rotation restricting groove 386 of the second member 352, and the rotation of the first member 351 in the first rotation direction R1 is stopped. Accordingly, the relative movement between the first member 351 and the second member 352 stops.

  Further, the engagement pin 396 of the third member 353 is engaged with the other end of the engagement groove 384 of the second member 352. As a result, the rotation of the third member main body 391 and the engagement assisting portion 392 in the first rotation direction R1 stops. That is, the relative movement between the first member 351 and the third member 353 stops.

  On the other hand, the first member 451 of the right movable unit 303 rotates in the second rotation direction R2 from the state shown in FIG. Then, the locking pin 475 of the first member 451 is engaged with the other end of the rotation restricting groove 486 of the second member 452, and the rotation of the first member 451 in the second rotation direction R2 is stopped. Further, the engagement pin 496 of the third member 453 engages with the other end of the engagement groove 484 of the second member 452, and the third member main body 491 and the engagement auxiliary portion 492 in the second rotation direction R2. Rotation stops.

Thereby, the left movable unit 302 and the right movable unit 303 of the movable decorative part 23 are arranged at the exposed position. As shown in FIG. 19, the left movable unit 302 and the right movable unit 303 arranged at the exposure position are arranged above the display window 4. As described above, the movable decorative portion 23 can rotate the first member 351 of the left movable unit 302 to rotate the second member 352 and the third member 353, the first member 451 of the right movable unit 303, and the second member 353. The member 452 and the third member 453 can be rotated.
Thereby, the movable decorative portion 23 can be deformed so as to gradually expand, and the movable decorative portion 23 can perform a dynamic motion.

Further, the axes of the engagement pins 396 and 496 of the third members 353 and 453 are shifted from the rotation shaft portions 394 and 494 (the rotation centers) of the third members 353 and 453.
Thus, a structure in which the first members 351 and 451 and the second members 352 and 452 relatively move to rotate the third members 353 and 453 can be realized with a simple configuration.

  Further, the second members 352 and 452 are rotatably connected to the first members 351 and 451, and the center of rotation (the connection shaft 377) of the second members 352 and 452 is connected to the first members 351 and 451. It coincides with the rotation center (rotation axis). Accordingly, when the second members 352 and 452 abut on the abutting portion 306, it can be seen that the second members 352 and 452 rotate in the same rotation center and in opposite directions. As a result, it is possible to make the operation of the movable decorative portion 23 a more dynamic operation.

  When moving the left and right movable units 302 and 303 from the exposure position to the standby position, the motor 331 (see FIG. 13) of the drive mechanism 304 is driven to rotate the rotation shaft 331a of the motor 331 in the first rotation direction R1. Let it.

  As a result, the crank 332 rotates in the first rotation direction R1, and the engagement pin 339 of the crank 332 engages with the first cam groove 341 of the slider 333, and the first rotation direction about the rotation shaft 331a. Displace to R1. As a result, the slider 333 is guided by the guide pins 334 and 335 and moves in the right direction X1 by the distance the engagement pin 339 moves in the right direction X1.

  The slider 333 that moves in the right direction X1 presses the engagement pin 378 in the right direction X1, and the engagement pin 378 engages with the second cam groove 342 of the slider 333, and the rotation shaft of the first member 351 ( (Coaxial with the connection shaft 377) in the second rotation direction R2.

  As a result, the first member 351 provided with the engagement pin 378 and the second and third members 352 and 353 connected to the first member 351 rotate in the second rotation direction R2 about the rotation axis. . At this time, the second and third members 352 and 353 rotate with respect to the first member 351. Thereby, the left movable unit 302 is arranged at the standby position while being deformed so that the first member 351, the second member 352, and the third member 353 are folded.

  Note that the first member 451 of the right movable unit 303 rotates by rotating the first member 351 of the left movable unit 302. Thereby, the right movable unit 303 is arranged at the standby position while being deformed so that the first member 451, the second member 452, and the third member 453 are folded.

  Further, in the present embodiment, the center of rotation (connection shaft 377) of the second members 352 and 452 in the movable decorative portion 23 matches the center of rotation (rotation axis) of the first members 351 and 451. did. However, the center of rotation of the second member according to the present invention does not have to coincide with the center of rotation of the first member.

  In the present embodiment, the first members 351 and 451 of the movable decorative portion 23 are rotated with respect to the base portion 301. However, the first member according to the present invention may be a member that moves linearly by a drive mechanism.

In the present embodiment, the second members 352 and 452 of the movable decorative portion 23 are rotatably connected to the first members 351 and 352. However, the second member according to the present invention may be connected to the first member so as to be linearly movable.
