  In the pachislot of this embodiment, medals are used as game media for playing games. In addition to the medals, coins, game balls, game point data, tokens, or the like can be applied as game media.

  When a player inserts a medal and operates the start lever, one value (hereinafter, random number value) is extracted from random numbers in a predetermined numerical range (for example, 0 to 65535).

  The internal lottery means performs lottery based on the extracted random number value and determines an internal winning combination. This internal lottery means is carried out by a main control circuit described later. By determining the internal winning combination, a combination of symbols that permits display along a winning determination line described later is determined. The types of symbol combinations include those related to “winning” in which benefits such as paying out medals, re-games, bonuses, etc. are given to players, and other so-called “loses”. Is provided.

  Further, when the start lever is operated, a plurality of reels are rotated. Thereafter, when the stop button is pressed by the player, the reel stop control means performs control to stop the rotation of the corresponding reel based on the internal winning combination and the timing when the stop button is pressed. The reel stop control means is responsible for a main control circuit described later.

  In the pachislot, basically, a control for stopping the rotation of the corresponding reel is performed within a specified time (190 msec or 75 msec) from when the stop button is pressed. 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 symbols”. When the specified period is 190 msec, the maximum number of sliding symbols is set to 4 symbols, and when the specified period is 75 msec, the maximum number of sliding symbols is set to 1 symbol.

  When the internal winning combination allowing the symbol combination display related to winning is determined, the reel stop control means usually displays the symbol combination within the specified time of 190 msec (four symbols) for the winning determination line. The rotation of the reel is stopped so as to display as much as possible. In addition, the reel stop control means is defined for one or more reels when, for example, a challenge bonus (CB), which is a second-type special accessory, and a middle bonus (MB) for continuously operating the CB are operated. The reel rotation is stopped so that the combination of symbols is displayed as much as possible along the winning determination line within a time of 75 msec (for one symbol). Furthermore, the reel stop control means uses various specified times corresponding to the gaming state to rotate the reels so that combinations of symbols that are not permitted to be displayed by the internal winning combination are not displayed along the winning determination line. Stop.

  Thus, when the rotation of the plurality of reels is all stopped, the winning determination means determines whether or not the combination of symbols displayed along the winning determination line is related to winning. This winning determination means is carried out by a main control circuit described later. When it is determined by the winning determination means that it is related to winning, a privilege such as paying out medals is given to the player. In the pachislot, a series of flows as described above is performed as one game.

  Further, in the pachislot, in the above-described series of flows, video display performed by a display device such as a liquid crystal display device, light output performed by various lamps, sound output performed by a speaker, or a combination thereof is used. Various productions are performed.

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

  When the content of the production is determined, the production execution means is linked to each opportunity such as when the rotation of the reel is started, when the rotation of each reel is stopped, or when the presence / absence of a prize is determined. To proceed with the production. This effect executing means is carried out by a sub-control circuit described later. In this way, in the pachislot machine, the player has the opportunity to know or predict the determined internal winning combination (in other words, the combination of symbols to be aimed at) by executing the production contents associated with the internal winning combination. It is possible to improve the player's interest.

The inner peripheral surface 141b of the bottom 141 that forms the through hole 141a shows a specific example of the inner wall surface of the case according to the present invention. A plurality of rolling elements 116A are in contact with the inner peripheral surface 141b. A plurality of rolling elements 116 </ b> B are in contact with the surface of the bottom portion 141 that faces the rotating member 113.

  As shown in FIG. 8, three mounting bosses 145 are provided on the outer peripheral surface of the side wall 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 therein. 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.

  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 outward in the radial direction of the side wall portion 142, and the outer contour is formed in an elliptical shape. A 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, a back surface 152, and a side surface 153 that are appearance surfaces. The outer diameter of the rotating member 113 is set smaller than the inner diameter of the side wall 142 in the case 112. The rotating member 113 is rotatably accommodated in the case 112.

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

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

  The back surface 152 is provided with an inner cylinder 156, an outer cylinder 157, and three rolling element accommodating portions 158. 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 141 a in the case 112. The inner cylinder 156 passes through the through hole 141 a in the case 112 and is inserted into the opening 133 a (see FIG. 7) of the second gear 133, and engages 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 141 a in the case 112. Thereby, the outer cylinder 157 penetrates the through hole 141 a in the case 112. The height at which the outer cylinder 157 protrudes from the back surface 152 is lower than the height at which the inner cylinder 156 protrudes from the back surface 152. Accordingly, the outer cylinder 157 does not interfere with the second gear 133.

  The outer peripheral surface of the outer cylinder 157 shows 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 accommodation recesses 157a are arranged at equal intervals along the circumferential direction of the outer cylinder 157, and each accommodate a spherical rolling element 116A in a rollable manner.

  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 in the radial direction of the outer cylinder 157 from the outer peripheral surface of the outer cylinder 157 and contacts the inner peripheral surface 141b of the case 112 (see FIG. 9).

  Three attachment 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 that protrudes vertically 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), respectively. Thereby, 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. For this reason, in a state where the rotating decoration portion 22 is attached to the decorative frame 101 (see FIG. 2), the axial direction (axial center line) of the rotating member 113 is inclined with respect to a plane perpendicular to the vertical direction. Is inclined so that the surface 151 faces obliquely downward.

  Note that the fixing of the rotating member 113 to the second gear 133 is not limited to using a screw, and for example, other fixing methods such as fixing using an adhesive, caulking fixing, and fitting fixing are adopted. be able to.

  The three rolling element accommodating portions 158 are provided on the outer edge portion of the back surface 152. And it arrange | positions along the circumferential direction of the back surface 152 at equal intervals. Each rolling element accommodating portion 158 is formed in a rectangular frame shape protruding from the back surface 152, and accommodates the spherical rolling element 116B in a rollable manner.

  The length which protrudes from the back surface 152 of the rolling element accommodating part 158 is shorter than the diameter of the rolling element 116B. Therefore, the rolling element 116B accommodated in the rolling element accommodating part 158 will protrude rather than the upper end surface of the rolling element accommodating part 158, and will contact the bottom part 141 of case 112 (refer FIG. 9).

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

  An edge portion 114 a of the case cover 114 is joined to the flange portion 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 through the case cover 114.

<Operation of rotating decoration>
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 unit 22 is caused to emit light and rotate.

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

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

  When the motor 131 is driven, a rotation shaft (not shown) of the motor 131 and the first gear 132 fixed to the rotation shaft rotate. The rotation of the first gear 132 is transmitted to the second gear 133 while being decelerated. As a result, 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. As a result, the weight of the rotating member 113 is distributed and applied to the rotating mechanism 115 and the case 112, and the load on the rotating mechanism 115 can be reduced. As a result, damage and failure of the rotation mechanism 115 can be suppressed.

  A plurality of rolling elements 116 </ b> A and 116 </ b> B are interposed between the rotating member 113 and the case 112. Thereby, when the rotating member 113 rotates with respect to the case 112, the three rolling elements 116 </ b> A rotate while contacting the outer peripheral surface of the outer cylinder 157 of the rotating member 113 and the inner peripheral surface 141 b 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 portion 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 brought into direct contact. As a result, the load on the rotation mechanism 115 can be further reduced.

  The outer peripheral surface of the outer cylinder 157 of the rotating member 113 and the inner peripheral surface 141b of the case 112 are opposed to each other in the radial direction of the rotating member 113 and sandwich the rolling elements 116A. On the other hand, the back surface 152 of the rotating member 113 and the bottom portion 141 of the case 112 face the radial direction of the rotating member 113 and sandwich the rolling elements 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 transmission portion 155 faces obliquely downward, the light transmission portion 155 can be directed to the player. As a result, it is possible to make the light emission and rotation operation of the rotary decoration portion 22 easily visible to the player.

  In the present embodiment, a through hole 141a is formed in the bottom 141 of the case 112, and the second gear 133 of the rotating mechanism 115 is fixed to the rotating member 113 through the through hole 141a. Thereby, the axial center line of the rotation member 113 and the axial center line of the 2nd gearwheel 133 can be made to correspond.

  Further, in the present embodiment, the rotation decoration portion 22 includes the mounting bracket 111. A substrate 125 on which the LED 126 is mounted is fixed to the mounting bracket 111. In addition, an opening 133a is formed in the 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 through the opening 133a of the second gear 133. .

  As a result, the light transmitting portion 155 of the rotating member 113 can appear to emit light. In addition, 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 applied to the first and second gears 132 and 133 and the motor 131 can be reduced even if the rotating member 113 is configured to emit light.

  In this 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 bulb or a fluorescent lamp may be used.

In the present embodiment, rolling element 116 </ b> A is interposed between the outer peripheral surface of outer cylinder 157 of rotating member 113 and inner peripheral surface 141 b 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 circumferential 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 in the case 112.

<Cooling structure of enclosed space>
Next, the closed space formed in the front door 2b and the 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 square 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 portion (right side as viewed from the back side) 108. The above-described movable decorative portion 23 is attached to the center portion on the back surface of the upper frame portion 105. A blower 201 is attached to a corner portion formed by the upper frame portion 105 and the right frame portion 108 on the back surface of the decorative frame 101.

The movable decorative portion 23 and the blower 201 are opposed to 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 behind 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 101 a by rotating with respect to the decorative frame 101. The configuration and operation of the movable decorative portion 23 will be described in detail later.

  As shown in FIG. 11, in this 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 portion 23 (not shown) and the blower 201 are disposed in the upper portion of the closed space 200.

  The closed space 200 is not a completely sealed space. For example, a fine 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 fine gap as described above.

  The blower 201 is a sirocco fan, for example, and blows air in the closed space 200 to lower the temperature in the closed space 200. The 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 the side peripheral surface.

  The blower 201 is arranged so that the air inlet 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 plane of the blower 201 and the back surface of the decorative frame 101. Further, the blower 201 is disposed so that the exhaust port 201b faces the left frame portion 107 of the decorative frame 101.

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

  The closed space 200 is not a completely sealed space but communicates with an external space. Therefore, when the air in the closed space 200 flows, it is possible to promote the entry and exit of air generated between the closed space 200 and the external space. As a result, heat can be prevented from accumulating in the enclosed space 200, and the temperature in the enclosed space 200 can be lowered.

The blower according to the present invention is preferably arranged in the upper part of the closed space 200. Thereby, the warm air which rose by the convection in the enclosed space 200 can be made to flow.
In addition, you may arrange | position the air blower which concerns on this invention in the intermediate part in the up-down direction of the closed space 200 or the closed space 200. As shown in FIG. Even in this case, the air in the enclosed space 200 can flow, and the temperature in the enclosed space 200 can be lowered.

  The air discharged from the exhaust port of the blower according to the present invention preferably travels along the display unit 11a. Thereby, the air heated by the display part 11a of the liquid crystal display device 11 can be efficiently flowed. Furthermore, it is preferable that the air discharged from the exhaust port of the blower according to the present invention travels horizontally along 11a. Thereby, the air in the enclosed space 200 can be stirred, and the temperature in the enclosed space 200 can be lowered.

  In addition, the air blower which concerns on this invention may be arrange | positioned so that the air discharged | emitted from an exhaust port may advance to an up-down direction along the display part 11a. Even in this case, the air heated by the display unit 11a of the liquid crystal display device 11 can be efficiently flowed.

<Lock of movable decorative part>
Next, the locking 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 decorative portion 23 are disposed at the standby position.

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

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

  The state of the right movable unit 303 is symmetrical with the state of the left movable unit 302. Therefore, from here, the state of the left movable unit 302 will be described, 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 disposed 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. Accordingly, 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-rear direction Y.

  Further, in a state where the left movable unit 302 is disposed 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 biased in the second rotational 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.

  Further, in a state where the left movable unit 302 is disposed at the standby position, the engagement 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. Further, the guide pins 334 and 335 attached to the base portion 301 are engaged with one ends of the engaging grooves 343 and 344 of the slider 333, respectively.

  Hereinafter, a direction from one end of the engagement groove 343 toward 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 toward 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 the engagement grooves 343 and 344 at one end, 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 first member 351 (left movable unit 302) is rotated in the second rotation direction R2. It is blocked.

Further, in a state where the left movable unit 302 is disposed 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. Thereby, the rotation of the crank 332 in the first rotation direction R1 is restricted.
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 (rotation center of the crank 332) of the rotation shaft 331a of the motor 331 (the first axis). (Position displaced in the rotation direction R1).

  Thereby, when the slider 333 presses the engagement pin 339 in the left direction X2, the crank 332 tries 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 is moved 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 first member 351 (the left movable unit 302) rotates in the first rotation direction R1. It is blocked.

  Since the tooth portion 476 of the right movable unit 303 meshes with the tooth portion 376 of the left movable unit 302, the right movable unit 303 does not rotate unless the left movable unit 302 rotates.

  As described above, 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. Thereby, even if vibration or impact is applied to the pachi-slot 1, the left and right movable units 302 and 303 of the movable decorative portion 23 can be prevented from coming into contact with other members constituting the pachi-slot 1.

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

In the present embodiment, in a state where the left movable unit 302 is disposed at the standby position, the axis of the engagement pin 339 is parallel to the left-right direction X and on a plane including the axis of the rotation shaft 331a. It was set as the structure arrange | positioned above a position.
However, the axis of the engagement pin 339 may be arranged on a plane including the axis (rotation center of the crank 332) of the rotation shaft 331a of the motor 331. 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 limited, and the engagement pin 378 of the first member 351 is not pressed in the left direction X2 by the slider 333. As a result, the first member 351 (left movable unit 302) is prevented from rotating in the first rotation direction R1.

<Operation of movable decorative 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 decorative portion 23 are 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 decorative portion 23 have moved relative to the first member from the state illustrated in FIG. 16. FIG. 18 is an explanatory diagram showing a state in which the left and right movable units 302 and 303 of the movable decorative portion 23 are further operated from the state shown in FIG. FIG. 19 is an explanatory view of the front panel 10 as viewed from the front when the left and right movable units 302 and 303 of the movable decorative portion 23 are disposed at the exposed positions.

  When the left and right movable units 302 and 303 are moved from the standby position shown in FIG. 15 to the exposed position shown in FIG. 18, the motor 331 (see FIG. 13) of the drive mechanism 304 is driven to rotate the rotating 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. Displacement to R2. As a result, as shown in FIG. 16, the slider 333 is guided by the guide pins 334 and 335 and moved in the left direction X2 by the distance that 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. Accordingly, the engagement pin 378 is displaced in the first rotation direction R1 around the rotation shaft (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 relative to the first member 351. That is, the left movable unit 302 rotates in the first rotation direction R1 around the rotation axis arranged at the standby position.

  The gear piece 373 of the left movable unit 302 is engaged 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 shaft 377), the right movable unit 303 becomes centered on the rotation axis (coaxial with the connection shaft 477). It rotates in the second rotation direction R2. Thereby, the left movable unit 302 and the right movable unit 303 rotate so as to approach each other from the standby position.

  Further, when the left movable unit 302 rotates in the first rotation direction R <b> 1, the linear portion 382 of the second member 352 in the left movable unit 302 comes into contact with the contact portion 306. Thereby, 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 R <b> 2, the linear portion 482 of the second member 452 in the right movable unit 303 comes into contact with the contact portion 306. Thereby, 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 in 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 about the rotation shaft (coaxial with the connecting shaft 377). To turn.

  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. As a result, the second member 352 rotates about the connecting 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 the second member 352 is viewed from the front panel 10 (see FIG. 19). The arc portion 381 is exposed.

  When the first member 351 and the second member 352 move relatively, the engagement pin 396 of the third member 353 moves from one end to the other end in 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 around the rotation shaft portion 394 with respect to the first member 351. That is, the first member 351 and the third member 353 move relatively. Note that the third member main body 391 and the engagement assisting portion 392 rotate in the first rotation direction R1 against the biasing 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 changes 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 together with the first member 451 but rotates around the connection shaft 477 with respect to the first member 451. That is, the first member 451 and the second member 452 move relatively.

  As the first member 451 and the second member 352 move relative to each other, the third member main body 491 and the engagement assisting portion 492 are moved with respect to the first member 451 around the rotation shaft portion 494. 2 in the direction of rotation 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 in 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 about the rotation shaft (coaxial with the connecting shaft 377). To turn.

  Accordingly, the second member 352 that is in contact with the contact portion 306 rotates about 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. As a result, the relative movement between the first member 351 and the second member 352 stops.

  Further, the engagement pin 396 of the third member 353 engages 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 is engaged with the other end of the engagement groove 484 of the second member 452, and the third member main body 491 and the engagement assisting portion 492 in the second rotation direction R2. The rotation stops.

Thereby, the left movable unit 302 and the right movable unit 303 of the movable decorative portion 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 simply rotates the first member 351 of the left movable unit 302, and the second member 352 and the third member 353, and the first member 451 and the second member 352 of the right movable unit 303. The member 452 and the third member 453 can be rotated.
Accordingly, the movable decorative portion 23 can be deformed so as to gradually expand, and the movable decorative portion 23 can be operated with a feeling of dynamism.

Further, the shaft centers of the engagement pins 396 and 496 of the third members 353 and 453 are shifted from the rotation shaft portions 394 and 494 (rotation center) of the third members 353 and 453.
As a result, the first member 351, 451 and the second member 352, 452 move relatively, whereby the structure in which the third member 353, 453 rotates 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 rotation centers (connection shafts 377) of the second members 352 and 452 are connected to the first members 351 and 451. It coincides with the rotation center (rotation axis). As a result, when the second members 352 and 452 are in contact with the contact 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, the operation of the movable decorative portion 23 can be made more dynamic.

  When the left and right movable units 302 and 303 are moved 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

  Thus, 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.
