[0029] Embodiments of the present invention will be described with reference to the accompanying drawings. Figures 1 to 3 The illustrated automaton clock 10 includes a frame 15 that is generally oblong when viewed from the front. A clock unit 50 is disposed slightly above the center of the frame 15. The clock unit 50 includes a minute hand 11, an hour hand 12, a second hand 13, and a divided dial 20 that divides a circular dial into multiple parts. The minute hand 11, hour hand 12, and second hand 13 are connected to a pointer shaft 14 and driven. In this embodiment, the divided dial 20 is divided into three first divided dials 21, each containing three numbers, and three second divided dials 22, each containing a single number.
[0030] Each divided dial 20 revolves around the pointer shaft 14 while rotating on its own axis due to the operation of the drive mechanism 100 included in the clock unit 50 . Figure 2 The split dial 20 shown is in the middle of operation.
[0031] Furthermore, the automaton timepiece 10 is provided with a rotating decorative portion 60 below the timepiece portion 50. The rotating decorative portion 60 is a decorative portion in which a decorative member 61 rotates.
[0032] In the following description, the front side of the automaton timepiece 10 is referred to as front, the back side is referred to as back, and the left side when viewing the automaton timepiece 10 from the front is referred to as left, the right side is referred to as right, the upper side is referred to as upper, and the lower side is referred to as lower.
[0033] Next, the clock section 50 and the driving mechanism 100 included in the clock section 50 will be described. Figure 4 As shown, the clock section 50 is provided inside the housing 15. The clock section 50 includes a movement 51. The minute hand 11, the hour hand 12, and the second hand 13 rotate around the axis CL of the pointer shaft 14 of the movement 51.
[0034] like Figure 4 and Figure 5 As shown, the base member 110 of the drive mechanism 100 is formed into a roughly circular plate shape. A shallow recess 111 is formed over a wide area on the front side of the base member 110. The outer periphery of the recess 111 is formed into a flange shape. A boss 112 is provided around the axis CL of the recess 111. The movement 51 is mounted on the back side of the base member 110, with the pointer shaft 14 protruding toward the front.
[0035] The base member 110 includes an internal gear 113 arranged in an annular shape around the axis CL. A drive gear 105 is exposed on the inner diameter side of the base member 110 at the upper left portion of the rear side of the internal gear 113. The motor 101 serving as the driving source of the drive mechanism 100 is provided on the outer peripheral portion of the upper left side of the base member 110. A pinion gear provided on the drive shaft (not shown) of the motor 101 is driven by a reduction gear 103 (see FIG. 1 ) composed of a plurality of gears. Figure 6 ), connected to the driving gear 105 and capable of transmitting rotational force.
[0036] Four branched guide members 117 are provided on the outer periphery of the recess 111 of the base member 110. The guide members 117 are arranged to sandwich an annular external gear 123 of the rotating member 120 described later, and reduce vibration of the rotation axis when the rotating member 120 rotates.
[0037] A roughly disk-shaped rotating member 120 is provided in the recess 111 of the base member 110. The front side of the rotating member 120 is formed into a roughly flat surface, and a boss 122 is provided around the axis CL. A fixed shaft 130 is inserted into the boss 122. The fixed shaft 130 has a flange portion at the front end. With the flange portion abutting the front end of the boss 122, the rear portion of the fixed shaft 130 is inserted and fixed within the boss 112 of the base member 110. The sliding contact between the inner circumferential surface of the boss 122 and the outer circumferential surface of the fixed shaft 130 allows the rotating member 120 to rotate about the axis CL.
[0038] A shallow recess 121 is formed over a wide area on the rear side of the rotating member 120. An external gear 123 is formed on the outer periphery of the rotating member 120, forming the edge of the rearwardly opening portion of the recess 121. The external gear 123 is arranged in an annular shape around the axis CL. The external gear 123 is positioned behind the internal gear 113 of the base member 110 and meshes with the drive gear 105.
[0039] On the front side of the rotating member 120, six gear shafts 124 are provided at equal intervals around the axis CL near the outer edge of the rotating member 120. In addition, six bosses 125 (also see FIG. 1 ) are provided between the gear shafts 124 on the front side of the rotating member 120. Figure 6 ).
[0040] A plurality of six gears 140 are rotatably mounted on respective gear shafts 124 on the front face of the rotating member 120. Of the six gears 140, the teeth of three gears 140-1, 140-2, and 140-3 are formed with a larger diameter than the teeth of the other three gears 140-4, 140-5, and 140-6. Gear 140-1 is rotatably supported by gear shaft 124-1. Similarly, gears 140-2, 140-3, 140-4, 140-5, and 140-6 are rotatably supported by gear shafts 124-2, 124-3, 124-4, 124-5, and 124-6, respectively. The three gears 140-1, 140-2, and 140-3 and the three gears 140-4, 140-5, and 140-6 are alternately arranged around the axis CL.
[0041] Each gear 140 is provided with a dial support portion 141 protruding forward in a generally cylindrical shape with a relatively thin axis length around the rotation axis of each gear 140 (the axis of the gear shaft 124). The dial support portions 141 of each gear 140 are formed to be approximately the same size. The diameter of the dial support portion 141 is smaller than the width of the main plate 26 that divides the dial 20. Therefore, the dial support portion 141 is hidden by the main plate 26 (see Figures 1 to 3 ). In addition, the gear 140 is meshed with the internal gear 113 (refer to Figure 6 ).
[0042] A concealed member 150 is provided on the front side of the rotating member 120. Figure 7 The concealed component 150 is formed in a generally annular shape around the axis CL. Six circular openings 151 are formed through the concealed component 150 around the axis CL. Corresponding to each opening 151, an arc portion 152 is formed on the concealed component 150, protruding in an arc shape in the inner diameter direction. The arc portion 152 is formed to mimic the outer shape of the gear 140 (the addendum circle of the gear 140).
[0043] Adjacent arc portions 152 are connected at their base ends by linear portions 153. The blind component 150 has a substantially radially open space S formed in its inner diameter by the multiple arc portions 152 and the multiple linear portions 153. Furthermore, the blind component 150 is provided with six small-diameter, circular, forged threaded holes 155 extending therethrough.
[0044] like Figure 4 and Figure 7 As shown, the concealed member 150 is fixed to the rotating member 120 by screwing the threaded hole 155 into the internal thread (not shown) of the boss 125 of the rotating member 120. Each opening 151 corresponds to the dial support 141 of each gear 140. The dial support 141 is exposed from the concealed member 150 through the opening 151.
[0045] The split dial 20 is provided with a plurality of bosses 27 on the back side of the main plate 26 on which the numerals indicating the hours, minutes, etc. are recorded. Figure 4 The boss 27 is formed with an internal thread, and a threaded member is screwed into the gear 140 from the rear side through a plurality of threaded holes 141a provided in the dial support portion 141 of the gear 140. This secures the split dial 20 to the gear 140. The gear 140 is connected to the split dial 20 at the front and is rotatably mounted on the rotating member 120 at the rear side via the gear shaft 124.
[0046] The bosses 27 of the three first divided dials 21 in the divided dial 20 are formed to be longer than the bosses 27 of the three second divided dials 22. Figure 3 and Figure 4 As shown, the main plate 26 of the first split dial 21 is located in front of the main plate 26 of the second split dial 22 .
[0047] The two ends of the main plate 26 of the first split dial 21 of the split dial 20 are formed into a substantially convex arc shape, and the two ends of the main plate 26 of the second split dial 22 are formed into a concave arc shape. In the split dial 20, when the two ends of the main plate 26 of the first split dial 21 and the second split dial 22 are connected and arranged, as shown in FIG. Figure 1 As shown, the plurality of main body plates 26 are arranged in a substantially annular shape.
[0048] A truss portion 28 protruding in a substantially triangular frame shape is provided on the main plate 26 of the divided dial 20. A decorative portion 28a imitating the shape of an electric bell is provided at the protruding end of the truss portion 28 of the first divided dial 21. Figure 1 While arranged in a substantially circular shape as shown, the truss portions 28 are arranged in a star shape.
[0049] When the motor 101 drives the drive mechanism 100, the drive gear 105 causes the rotating member 120 to rotate about the axis CL. As the rotating member 120 rotates about the axis CL, the multiple gears 140 meshing with the internal gear 113 rotate about the axis of the gear shaft 124. Consequently, the gears 140 orbit around the axis CL while rotating about the axis of the gear shaft 124. Consequently, the divided dial 20, which is fixed to the gears 140, orbits around the axis CL while rotating about the axis of the gear shaft 124.
[0050] Here, the rotating member 120 is formed of a light-transmitting material. The light-transmitting material refers to the shape of the member disposed on the rear side (of the rotating member 120), which cannot be clearly seen from the front, but light from the rear side can be seen from the front. Alternatively, the rotating member 120 may be formed transparent.
[0051] The concealing member 150 is formed of an opaque material that does not transmit light. The front, back, or both sides of the concealing member 150 are preferably painted black. This allows light from the light emitting unit 230, which will be described later, to be shielded.
[0052] The hidden component 150 is disposed between the divided dial 20 and the tooth portion of the gear 140, as shown in FIG. Figure 7 As shown, at least the teeth of gear 140 are covered. Therefore, at least the teeth of gear 140 cannot be visually recognized from the front. In this embodiment, only the dial support portion 141 of gear 140 is exposed from the concealing member 150. The dial support portion 141 of gear 140 cannot be visually recognized from the front due to the split dial 20 (main body plate 26) attached to the dial support portion 141.
[0053] Furthermore, two pattern sheets 200 are positioned between the rotating member 120 and the base member 110. The pattern sheets 200 are made by printing or other methods on a transparent resin sheet with an arbitrary pattern. Each pattern sheet 200 has a circular opening 201 at its center. The opening 201 is slightly larger than the outer shape of the boss 112 of the base member 110.
[0054] Of the two pattern sheets 200, the first pattern sheet 210 on the rear side is disposed on the recess 111 of the base member 110 and is fixed to the front end of the cylindrical portion 111a formed around the axis CL (see also FIG. Figure 4 The front second pattern piece 220 is fixed to the rear surface of the rotating member 120, i.e., the recess 121. The front surface of the first pattern piece 210 and the rear surface of the second pattern piece 220 are arranged adjacent to each other, and the opening 201 prevents interference with the boss 122 and the fixed shaft 130. The pattern piece 200 is arranged concentrically with the axis CL.
[0055] The pattern of the pattern sheet 200 can be formed by a light-transmitting portion that transmits light and a light-blocking portion that does not transmit light. The light-transmitting portion can be formed by not printing or lightly printing to allow the transparent resin sheet to pass through. The shielding portion can be formed by printing such as blackening.
[0056] Here, the pattern provided on the first pattern sheet 210 is referred to as the first pattern 202-1, and the pattern provided on the second pattern sheet 220 is referred to as the second pattern 202-2. In this embodiment, the first pattern 202-1 and the second pattern 202-2 are the same pattern. In other words, the first pattern sheet 210 and the second pattern sheet 220 are the same pattern sheet 200.
[0057] For example, Figure 8 An example of a pattern sheet 200 is shown. In pattern 202, the portion indicated by white paint is a translucent portion 202a that allows light to pass through, and the portion indicated by black paint is a shielded portion 202b that blocks light and blocks it. Pattern 202 includes 12 triangular portions 203 and 12 diamond-shaped portions 204. The triangular portions 203 are formed into a thin triangular shape by the translucent portions 202a and the shielded portions 202b. The 12 triangular portions 203 are arranged radially at equal intervals around the axis CL. The diamond-shaped portions 204 are arranged between the triangular portions 203 at equal intervals around the axis. The diamond-shaped portions 204 are formed inside the diamond-shaped translucent portion 202a, so that approximately half of the diamond shape becomes the shielded portion 202b.
[0058] In this embodiment, two Figure 8 The pattern piece 200 is used as the first pattern piece 210 and the second pattern piece 220. The first pattern 202-1 and the second pattern 202-2 are the same. Figure 5 As shown, a light-emitting unit 230, such as a blue light-emitting diode (LED), is disposed within the cylindrical portion 111a of the recessed portion 111 of the base member 110. When the automatic timepiece 10 is viewed from the front, light from the light-emitting unit 230 can be seen through the light-transmitting portion 202a of the pattern sheet 200 via the rotating member 120 exposed in the space S of the concealed member 150. This allows the pattern formed by the light-transmitting portion 202a and the shielded portion 202b of the pattern sheet 200 to be viewed from the front.
[0059] The rotating member 120 rotates around the axis CL relative to the base member 110. At a position where the first pattern 202-1 and the second pattern 202-2 of the first pattern sheet 210 provided on the rotating member 120 are consistent, as shown in FIG. Figure 8 As shown, it is visually recognized as being the same as the first pattern 202 - 1 (the second pattern 202 - 2 ).
[0060] Here, for example, when the rotating member 120 is rotated 3 degrees counterclockwise when viewed from the front, it is visually recognized as Figure 9 The pattern shown, Figure 10 The pattern is further rotated 3 degrees counterclockwise, and the pattern is the same as Figure 11 、 Figure 12 、 Figure 13 By continuously rotating the rotating member 120, the pattern can appear to be continuously changing.
[0061] In addition, in this embodiment, the first pattern 202-1 and the second pattern 202-2 are the same pattern, but can also be set, for example, to set the line width of the light-transmitting portion 202a that appears to be linear to be slightly different on the first pattern 202-1 and the second pattern 202-2, etc., by making several changes to the two to form them to be roughly the same, so that the pattern of light seen through the two pattern sheets 200 looks more beautiful.
[0062] Alternatively, the first pattern 202-1 and the second pattern 202-2 may be completely different. For example, by creating a city pattern with multiple buildings on the fixed-side first pattern 202-1 and a star-studded pattern surrounding the buildings in the first pattern 202-1 on the movable-side second pattern 202-2, a pattern resembling a city starry sky can be created.
[0063] Figure 14 、 Figure 15 A base member 110A according to a modified example of the base member 110 in the above embodiment is shown. In the following description, the same members or locations as those in the above embodiment are denoted by the same reference numerals, and their descriptions are omitted or simplified.
[0064] On the inner diameter side of the cylindrical portion 111a of the recess 111 of the base member 110A, there are provided six sheet bases 111b connected to the inner circumference of the cylindrical portion 111a and protruding toward the front side in a roughly semicircular shape. The plurality of sheet bases 111b are radially arranged at equal intervals around the axis CL. Figure 15 As shown, multiple sheet pedestals 111b are formed into a concave shape on the rear side of the base member 110A. The first pattern sheet 210 is placed on the six sheet pedestals 111b on the front side of the base member 110A. A V-shaped protrusion 111a1 is provided on the upper inner circumference of the cylindrical portion 111a. This protrusion engages with a V-shaped notch (not shown) formed on the first pattern sheet 210. This secures the first pattern sheet 210 to the base member 110A.
[0065] like Figure 14As shown in the figure surrounded by the P1 portion, four reinforcing ribs 301 are radially provided on the outer periphery of the boss 112A provided on the front side around the axis CL of the base member 110A. In addition, two locking protrusions 302 are provided on the front end of the outer periphery of the boss 112A. The two locking protrusions 302 are respectively provided at the upper and lower sides between the ribs 301 around the axis CL. Figure 16 As shown, the inner diameter of the opening portion 201-1 (first opening) of the first pattern sheet 210 is approximately the same as the outer diameter D1 of the boss 112A, i.e., it is large enough to be inserted through the outer diameter D1 of the boss 112A. Furthermore, the periphery of the opening portion 201-1 is located behind the locking protrusion 302, so the opening portion 201-1 and the locking protrusion 302 are locked together. This prevents the central portion of the first pattern sheet 210 from floating.
[0066] Reference Figure 14 The graph surrounded by P1 and Figure 17 On the inner diameter side of boss 112A, a circular hole 303, coaxial with axis CL, is provided, through which the pointer shaft 14 of movement 51 is inserted. Threaded holes 304 are provided above and below circular hole 303. A threaded member 305 is inserted from the rear side of base member 110A through threaded hole 304 and secured to boss 112A of base member 110A by screwing into the threaded portion of fixed shaft 130. Furthermore, pin holes 306 are provided on the left and lower right sides of circular hole 303 for inserting pins (not shown) that protrude rearward from fixed shaft 130, thereby positioning fixed shaft 130 within base member 110A.
[0067] The base member 110A is provided with a plurality of openings 310a, 310b, and 310c that expose the plurality of LEDs 311 toward the front of the base member 110A. Opening 310a is a circular through-hole provided on the upper left side of the boss 112A. Opening 310b is a circular through-hole provided on the upper right side of the boss 112A. Opening 310c is formed by connecting two generally rectangular through-holes, exposing the LEDs 311.
[0068] like Figure 15 As shown, a light emitting circuit substrate 312 is provided at the substantially central portion of the rear surface of the base member 110A. On the rear side of the light emitting circuit substrate 312, an organic core 51 (see FIG. 5 ) is installed at a predetermined interval. Figure 16). The light-emitting circuit substrate 312 is provided with a plurality of LEDs 311 as a light-emitting portion composed of a plurality of semiconductor light-emitting elements on the front side of the light-emitting circuit substrate 312. The light-emitting circuit substrate 312 is provided with a left protrusion 312a protruding to the left (left when viewed from the front) and a right protrusion 312b protruding to the right (right when viewed from the front) on the upper side. A central opening 312c that is longer in the vertical direction and opens corresponding to the circular hole 303 and the threaded hole 304 is provided in the center of the light-emitting circuit substrate 312. On the light-emitting circuit substrate 312, a first locking portion 312d protruding upward is provided above the central opening 312c. In addition, on the light-emitting circuit substrate 312, a second locking portion 312e protruding downward is provided below the central opening 312c.
[0069] In addition, bosses 315 are provided on the left and right sides of the first locking portion 312d to abut against the front of the movement 51. In addition, pins 316 are provided on the left and right sides of the central opening 312c for positioning the movement 51 and the base component 110A. The light-emitting circuit substrate 312 has an opening of a shape or a circular hole that avoids interference with the bosses 315 and the pins 316. In addition, a boss 317 is provided below the pin 316 below the left protrusion 312a and below the right protrusion 312b, which is slightly higher than the other bosses 315. An internal thread portion is provided on the boss 317. The boss 317 is inserted into and abuts against a hole portion (not shown) of the movement 51, and a threaded component (not shown) is screwed into the internal thread portion of the boss 317 from the back of the movement 51, thereby fixing the movement 51 to the base component 110A.
[0070] The base part 110A is provided with: a first latched portion 321, which is latched with the first latching portion 312d of the light-emitting circuit substrate 312 by means of a concave-convex fit; and a second latched portion 322, which is latched with the second latching portion 312e of the light-emitting circuit substrate 312. The first latched portion 321 protrudes into a substantially long rectangle that is longer in the left-right direction. Figure 16 As shown in FIG. 1 , a concave locking recess 321a is provided on the upper side of the first locked portion 321. The lower side of the first locked portion 321 is open to communicate with the locking recess 321a. In addition, when the base member 110A is viewed from the front, above the boss 112A (see FIG. 1 ), the boss 112A is provided with a recess 321a. Figure 14 ) is provided with an elongated rectangular hole 321b corresponding to the locking recess 321a of the first locked portion 321. The elongated rectangular hole 321b is a hole for forming the second locked portion 322 (locking recess 321a) by injection molding.
[0071] like Figure 14 and Figure 15As shown, the second latched portion 322 is provided with a substantially U-shaped leaf spring portion 322a with its open side facing leftward. One end of the leaf spring portion 322a is a free end, and the other end is connected to the base member 110A. A substantially rectangular gripping portion 322b is provided on one end side of the leaf spring portion 322a, i.e., the free end side. Figure 16 As shown, a locking protrusion 322c is provided on the upper side of the gripping portion 322b. The second locked portion 322 is provided with elasticity in the vertical direction by the leaf spring portion 322a.
[0072] The light-emitting circuit substrate 312 is mounted on the base member 110A as follows. First, the first latching portion 312d of the light-emitting circuit substrate 312 is inserted into the latching recess 321a from the lower side of the open first latched portion 321. As a result, the first latching portion 312d is latched on the first latched portion 321 (latching recess 321a). In this state, the second latching portion 312e is slid on the upper surface of the gripping portion 322b of the second latched portion 322 and pressed to the front side. Since the gripping portion 322b is formed in a tapered shape inclined toward the front side, the second latching portion 312e is smoothly pressed in. Furthermore, by compressing the leaf spring portion 322a, the protruding end of the second latching portion 312e passes over the latching protrusion 322c and is arranged on the front side of the latching protrusion 322c.
[0073] When the second locking portion 312e is locked to the second locked portion 322, the leaf spring portion 322a applies force upward to the light-emitting circuit substrate 312. Therefore, the first locking portion 312d and the first locked portion 321 are securely locked. When removing the light-emitting circuit substrate 312, by pressing down the gripping portion 322b, the protruding end of the second locking portion 312e easily passes over the locking protrusion 322c and is positioned behind the locking protrusion 322c. As a result, the upward force acting on the light-emitting circuit substrate 312 is released, allowing the first locking portion 312d to detach from the first locked portion 321, thereby releasing the locking due to the concave-convex interlocking. This improves maintainability because the light-emitting circuit substrate 312 can be easily removed.
[0074] Figure 17 The rotating component 120A involved in a modified example of the present embodiment is shown. Here, a plurality of latching openings 323 are provided around the axis CL near the outer periphery of the second pattern piece 220. On the other hand, a plurality of latching portions 324 are provided on the rotating component 120A so as to correspond to the latching openings 323. The latching portion 324 includes a leaf spring portion 324a. One end of the leaf spring portion 324a is a free end, and the other end is fixed to the rotating component 120A and is formed into a roughly circular arc shape. A latching protrusion 324b (also refer to FIG. 3 ) which protrudes toward the rear and is formed into a hook shape is provided on the protruding end portion of one end side of the leaf spring portion 324a. Figure 17(See the figure surrounded by portion P2 of the figure). The locking protrusion 324b is inserted into the locking opening 323 and locked therewith. Specifically, the jaw portion of the locking protrusion 324b is positioned corresponding to the edge of the locking opening 323, and the locking protrusion 324b is locked with the locking opening 323. The second pattern piece 220 is attached by the locking protrusion 324b and the locking opening 323, and it does not easily fall off the rotating member 120A.
[0075] The second opening 201 - 2 opened in the center of the second pattern sheet 220 is arranged concentrically with the axis CL. Figure 17 The diameter D2 of the second opening 201-2 is larger than Figure 16 The outer diameter D3 of the fixed shaft 130 shown is smaller than the outer diameter D1 of the boss 112A. Consequently, even in the event of dimensional changes over time or assembly errors, the rear side of the boss 122 of the rotating component 120A does not directly contact the protruding end of the boss 112A of the base component 110A. Instead, the rear side of the edge of the second opening 201-2 of the resin second pattern sheet 220 contacts and slides with the protruding end of the boss 122A. Therefore, even without the use of a separate sliding member, the rotation of the rotating component 120A can reduce friction between the opening edge portion around the axis CL of the rotating component 120A and the protruding end of the boss 112A.
[0076] As described above, according to an embodiment of the present invention, the automaton clock 10 includes: a base member 110 having an internal gear 113 formed around an axis CL; a rotating member 120 in which a plurality of gears 140 connected to the divided dial 20 and meshing with the internal gear 113 are rotatably arranged in an annular shape, are formed of a light-transmitting material, and are rotatably provided on the base member 110 around the axis CL; a first pattern piece 210 having a first pattern 202-1 and fixedly provided on the base member 110 between the base member 110 and the rotating member 120; and a second pattern piece 220 having a second pattern 202-2 and fixedly provided on the rotating member 120 between the base member 110 and the rotating member 120.
[0077] Thus, the multiple gears 140 that drive the divided dial 20 and the internal gear 113 that meshes with the gears 140 can be arranged radially outward from the axis CL, thereby ensuring a central portion around the axis CL. Furthermore, since the pattern pieces 200 (a first pattern piece 210 and a second pattern piece 220) are provided on each of the base member 110 and the rotating member 120 that rotates relative to the base member 110, a decorative portion with a movable pattern, such as a pattern that continuously changes as the second pattern piece 220 moves relative to the first pattern piece 210, can be provided in the central portion of the ensured space.
[0078] In addition, the first pattern 202-1 and the second pattern 202-2 are substantially the same, thereby creating a decorative effect that looks like moving light.
[0079] Alternatively, the first pattern 202 - 1 and the second pattern 202 - 2 may be different. In this case, a pattern may be presented in which the first pattern 202 - 1 moves relative to the second pattern 202 - 2 .
[0080] In addition, the first pattern piece 210 and the second pattern piece 220 are formed in circular shapes with the same diameter and are arranged concentrically with the axis CL. This can make the moving pattern presented by the pattern piece 200 more beautiful.
[0081] Furthermore, the first pattern piece 210 and the second pattern piece 220 are arranged concentrically with the axis CL. The base member 110A is provided with a boss 112A around the axis CL. The rotating member 120A is rotatably supported by a fixed shaft 130 fixed to the boss 112A. The first pattern piece 210 has an opening 201-1, i.e., a circular first opening provided to match the axis CL. The outer circumferential surface of the boss 112A is provided with a locking protrusion 302 that locks with the peripheral edge of the opening 201-1. Thus, even if the first pattern piece 210 is made of a thin resin sheet, the central portion around the axis CL is prevented from floating.
[0082] Furthermore, the first pattern piece 210 and the second pattern piece 220 are arranged concentrically with the axis CL. The base member 110A is provided with a boss 112A around the axis CL. The rotating member 120A is rotatably supported by a fixed shaft 130 fixed to the boss 112A. The second pattern piece 220 has an opening 201-2, i.e., a circular second opening provided to match the axis CL. The diameter D2 of the opening 201-2 is larger than the outer diameter D3 of the fixed shaft 130 and smaller than the outer diameter D1 of the boss 112A. As a result, the opening 201-2 of the second pattern piece 220 can be positioned between the protruding end of the boss 112A and the rotating member 120A, thereby reducing sliding friction.
[0083] Furthermore, the second pattern piece 220 has a plurality of locking openings 323, and the rotating component 120A has a plurality of locking portions 324 provided corresponding to the locking openings 323. The locking portion 324 has one end as a free end and the other end fixed to the rotating component 120A. The locking portion 324 is provided on one end of a spring portion 324a having an elastic arc shape and includes a locking protrusion 324b that is inserted into and locked in the locking opening 323. This ensures that the second pattern piece 220 is securely fixed to the rotating component 120A.
[0084] Furthermore, a light emitting unit 230 is provided on the base member 110 behind the first pattern sheet 210. This allows strong light from the light emitting unit 230 to be emitted from behind the rotating member 120, thereby allowing a clearer moving pattern to be visually recognized.
[0085] While the embodiments of the present invention have been described above, the present invention is not limited to these embodiments and can be implemented with various modifications. For example, in this embodiment, the rotating member 120 is rotatably mounted on the base member 110 by fixing the base member 110. However, the rotating member 120 only needs to be rotatable relative to the base member 110 about the axis CL. For example, both the base member 110 and the rotating member 120 can rotate about the axis CL.
