Description

【Technical Field】 【0001】 The present invention relates to a puppet display device. 【Background Art】 【0002】 Conventionally, as a display device that uses seven segment parts to display numbers from 0 to 9, for example, there is a magnetic inversion type display device as shown in Patent Document 1. This display device has a mechanism in which each of the seven segment parts is rotatably supported by a permanent magnet, and each segment part is independently inversion-controlled by an electromagnet. 【Prior Art Documents】 【Patent Documents】 【0003】 【Patent Document 1】 Japanese Patent Laid-Open No. 59-100489 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0004】 However, such a display device has movement only in the seven segment parts and no movement in other parts. In addition, since the mechanism of "moving" such a display device is not visible to the eye, there is little fun in picking it up and following its movement with the eyes. For example, when used for indoor interiors or toys, it has low attractiveness. 【0005】 The present invention has been made to solve the above conventional problems, and an object thereof is to provide a puppet display device with a high degree of attractiveness that has a simple basic configuration and many moving elements. 【Means for Solving the Problems】 【0006】 The present invention relates to a mechanical display device capable of displaying multiple numbers and / or multiple English letters, comprising seven segment sections: a first segment section located on the upper edge, a second segment section located on the middle edge, a third segment section located on the lower edge, two fourth segment sections located between the first and second segment sections, and two fifth segment sections located between the second and third segment sections, the device comprising: a first rotation axis located at one end of the first segment section, integrally supporting the first segment section and one of the two fourth segment sections located below that end; a second rotation axis located between the other fourth segment section of the two fourth segment sections and one of the two fifth segment sections located below the other fourth segment section, on the opposite side of the first rotation axis, supporting at least one of the segment sections: the other fourth segment section, the one fifth segment section, and the second segment section; and on the same side as the first rotation axis The structure comprises a third rotating shaft positioned at one end of the third segment portion and integrally supporting the third segment portion and the other fifth segment portion of the two fifth segment portions, a main frame body that rotatably supports the first rotating shaft, the second rotating shaft, and the third rotating shaft, a first programmed gear body for rotating the first rotating shaft, a second programmed gear body for rotating the second rotating shaft, and a third programmed gear body for rotating the third rotating shaft, all of which are integrally supported coaxially by the main frame body The device comprises a main gear assembly rotatably supported on a shaft, a first gear mechanism that meshes with the first programmed gear body and rotates the first rotating shaft, a second gear mechanism that meshes with the second programmed gear body and rotates the second rotating shaft, and a third gear mechanism that meshes with the third programmed gear body and rotates the third rotating shaft. By rotating the main gear assembly, the first rotating shaft, the second rotating shaft, and the third rotating shaft are rotated, and the aforementioned problem is solved by displaying the plurality of numbers and / or plurality of English letters. 【0007】 In this invention, seven segment sections are distributed and supported on a first, second, and third rotation axis. By rotating the main gear assembly, the first, second, and third rotation axes are rotated, making it possible to display multiple numbers and / or multiple English letters. Therefore, not only are the displayed numbers changing, but the rotation of the first, second, and third gear mechanisms that move the first, second, and third rotation axes is also generated by the rotation of the main gear assembly. In other words, these movements, along with the changes in the numbers, can be visually observed by people present at the scene. [Effects of the Invention] 【0008】 According to the present invention, it is possible to provide a highly engaging mechanical display device with an easy-to-understand basic structure and many moving elements.

[Modes for carrying out the invention] 【0010】 Hereinafter, the first embodiment of the present invention will be described with reference to FIGS. 1 to 12. Note that the present invention is not limited to the content described in the following embodiments. Also, the constituent elements in the following embodiments include those that can be easily assumed by those skilled in the art, substantially the same ones, and those within the so-called equivalent range. Furthermore, the constituent elements disclosed in the following embodiments may be combined as appropriate or selectively used as appropriate. 【0011】 As shown in FIGS. 1(A) and 2(A), the mechanical display device 100 is a display device that can display numbers from 0 to 9 using the seven segment portions 114 of the number display portion 112. Specifically, the mechanical display device 100 includes a display frame 102, a main body frame body 104, a first rotation shaft 116, a first gear mechanism 118, a second rotation shaft 120, a second gear mechanism 122, a third rotation shaft 124, a third gear mechanism 126, a main gear configuration body 130, a winding-up mechanism 140, and a lifting mechanism 160. With such a configuration, the mechanical display device 100 is configured to rotate the first rotation shaft 116, the second rotation shaft 120, and the third rotation shaft 124 by rotating the main gear configuration body 130 and display numbers in ascending order. 【0012】 Note that the mechanical display device 100 is, for example, in a form where most of it is a plate-like laminated wood material made of wood fibers joined together with metal bolts and nuts. The number displayed can be changed by moving the lever 156 by hand, and it has a familiar and affordable size (for example, about 10 cm in height, 7 cm in width, and 7 cm in depth). 【0013】 Hereinafter, each element will be described in detail. 【0014】 As shown in Figures 1(A) and 2(A), the display frame 102 is supported by the main frame 104 via bolts (not shown) through holes Hn1 and is positioned in front of the seven segment sections 114. The display frame 102 has an opening 102A that allows all the segment sections 114 to be visible from the front of the display frame 102 when the number 8 is displayed by the seven segment sections 114, that is, only the inside of the segment display area defined by the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 to be visible. In other words, as shown in Figure 1(A), the display frame 102 has a frame width that covers more than half of the segment sections 114 that are outside the segment display area. 【0015】 As shown in Figure 1(A), the main frame 104 comprises a first frame 106, a second frame 108, and a third frame 110. The first frame 106, the second frame 108, and the third frame 110 are integrated with each other via bolts (not shown) through holes Hn2, Hn3, and Hn4, respectively. 【0016】 As shown in Figure 4(A), the first frame 106 rotatably supports the first rotation shaft 116, the second rotation shaft 120, and the third rotation shaft 124. Holes Hn22 and Hn23 in Figure 11 rotatably support the reading shafts 118C and 126C, which will be described later, respectively. Holes Hn24 and Hn25 are connected to holes Hn27 and Hn28 of the intermediate frame 107 by bolts (not shown), respectively, and the intermediate frame 107 is attached to the first frame 106. Hole Hn26 is for rotatably supporting the reversing gear 122AB (see Figure 3), which will be described later, on the first frame 106. Hole Hn29 is a hole in the intermediate frame 107 for rotatably supporting the reading shaft 126C. The second frame 108 is a component for rotatably supporting the reading shafts 118C and 126C and the second advance gear 166, which will be described later. In fact, the hole Hn31 shown in Figures 1(B) and 2(B) rotatably supports the reading shaft 126C. The third frame 110 is a component for rotatably supporting the drive shaft 154, which will be described later, and the second advance gear 166. In fact, the hole Hn41 shown in Figures 1(B) and 2(B) rotatably supports the reading shaft 126C. 【0017】 As shown in Figure 3, the digital display unit 112 comprises seven segment sections 114, a first rotating shaft 116, a first gear mechanism 118, a second rotating shaft 120, a second gear mechanism 122, a third rotating shaft 124, a third gear mechanism 126, and three regulating levers 119, 123, and 127. As shown in Figure 1(A), the seven segment sections 114 consist of a first segment section 114A located on the top edge, a second segment section 114B located on the middle edge, a third segment section 114C located on the bottom edge, two fourth segment sections 114D and 114E located between the first segment section 114A and the second segment section 114B, and two fifth segment sections 114F and 114G located between the second segment section 114B and the third segment section 114C. 【0018】 As shown in Figures 1(A), 2(A), 2(C), and 2(D), the first rotating shaft 116 is positioned at one end (left end) of the first segment portion 114A and integrally supports the first segment portion 114A and one of the four fourth segment portions 114D and 114E positioned below that end (left end). Note that in Figure 3, the first rotating shaft 116 is not shown, so its place is indicated by a dashed line (the same applies to the reading shafts 118C, 122C, 126C, the second rotating shaft 120, and the third rotating shaft 124). 【0019】 The first gear mechanism 118 shown in Figure 3 meshes with the first program gear body 134, which will be described later, and rotates the first rotating shaft 116. The first gear mechanism 118 comprises a shaft gear 118A, a braking member 118AA, a drive gear 118B, reading gears 118BA and 118BB, and a reading shaft 118C (see Figure 2(D)). The shaft gear 118A is, for example, a spur gear with M (module) = 0.5 and n (number of teeth) = 18, and is mounted on the first rotating shaft 116. The braking member 118AA is a substantially circular member with recesses arranged symmetrically four times, and is mounted on the first rotating shaft 116 on the back of the first frame 106. The drive gear 118B is, for example, a spur gear with M=0.5 and n=36 teeth, and is mounted on the reading shaft 118C so as to mesh with the shaft gear 118A, and is rotatably supported on the first frame 106. As shown in Figures 4(B) and 4(C), the pair of reading gears 118BA and 118BB each have n=4 teeth and the same shape, and are integrated so that their phases are 45 degrees apart. In this state, the reading gears 118BA and 118BB have M=1.5 and n=8 teeth, and are mounted on the reading shaft 118C on the back of the first frame 106. Therefore, when the angle of one tooth of the reading gears 118BA and 118BB rotates by 45 degrees, the first rotation shaft 116 rotates by 90 degrees. 【0020】 The restrictor lever 119 is a component that ensures the first rotation axis 116 stops stably at 90-degree intervals. As shown in Figure 3, the restrictor lever 119 comprises an extended portion 119A, a fixed portion 119B, a leaf spring portion 119C, a connecting portion 119D, and a braking bearing 119E (not shown in Figure 3). The extended portion 119A is integrally provided with the fixed portion 119B. The extended portion 119A is designed so that when the fixed portion 119B is bolted to the first frame 106, its side surface contacts the first frame 106 to prevent the restrictor lever 119 from rotating around the bolt even if the bolt loosens. The fixed portion 119B has a hole through which a bolt is inserted to fix the restrictor lever 119 to the first frame 106. The leaf spring portion 119C supports the connecting portion 119D provided at its tip and is integrally attached to the fixing portion 119B. It elastically deforms so that it returns to its original position even if the connecting portion 119D is displaced. The connecting portion 119D supports the braking bearing 119E through a hole provided in itself. The braking bearing 119E is positioned to fit into a recess in the braking member 118AA. As a result, the braking member 118AA, i.e., the first rotation axis 116, is configured to rotate only in 90-degree increments. 【0021】 As shown in Figures 1(A), 2(A), 2(C), and 2(D), the second rotation shaft 120 is positioned between the other fourth segment portion 114E of the two fourth segment portions 114D and 114E and one of the five fifth segment portions 114G of the two fifth segment portions 114F and 114G located below the other fourth segment portion 114E. The second rotation shaft 120 is positioned on the opposite side of the first rotation shaft 116 and integrally supports the other fourth segment portion 114E, the one fifth segment portion 114G, and the second segment portion 114B (at the right end of the second segment portion 114B). 【0022】 As shown in Figure 3, the second gear mechanism 122 meshes with the second program gear body 132, which will be described later, and rotates the second rotating shaft 120. The second gear mechanism 122 comprises an axle gear 122A, a reversing gear 122AB, a drive gear 122B, reading gears 122BA and 122BB, and a reading shaft 122C (see Figures 2(C) and 2(D)). The axle gear 122A is, for example, a spur gear with M=1.5 and n=8, and is mounted on the second rotating shaft 120. The reversing gear 122AB is, for example, a spur gear with M=1.5 and n=13, and is rotatably supported on the first frame 106 so as to mesh with the axle gear 122A. The drive gear 122B is, for example, a spur gear with M=1.5 and n=16, and is mounted on the reading shaft 122C so as to mesh with the reversing gear 122AB, and is rotatably supported on the first frame 106. Note that the reading gears 122BA and 122BB have the same configuration as the reading gears 118BA and 118BB, so their explanation is omitted. Therefore, the second gear mechanism 122 is configured such that when the reading gears 122BA and 122BB rotate by an angle of 45 degrees by the teeth of one gear, the second rotating shaft 120 rotates by 90 degrees. Here, since the second gear mechanism 122 is equipped with a reversing gear 122AB, the direction of rotation due to the rotation of the main gear assembly 130 is in the opposite direction to the direction of rotation of the first gear mechanism 118. 【0023】 The restricting lever 123, like the restricting lever 119, is a component that ensures the second rotation shaft 120 rotates stably every 90 degrees. As shown in Figure 3, the restricting lever 123 comprises an extended portion 123A, a fixed portion 123B, a leaf spring portion 123C, a connecting portion 123D, and a braking bearing 123E. Since it has the same function and configuration as the restricting lever 119, a detailed explanation is omitted. Unlike the restricting lever 119, the braking bearing 123E of the restricting lever 123 directly presses against the two teeth of the shaft gear 122A simultaneously. Therefore, if the second rotation shaft 120 is capable of rotating in 45-degree increments, it is also possible to restrict its rotation in 45-degree increments. 【0024】 As shown in Figures 1(A), 2(A), 2(C), and 2(D), the third rotating shaft 124 is on the same side as the first rotating shaft 116 and is positioned at one end (left end) of the third segment portion 114C, integrally supporting the third segment portion 114C and the other fifth segment portion 114F of the two fifth segment portions 114F and 114G. 【0025】 As shown in Figure 3, the third gear mechanism 126 meshes with the third program gear body 136, which will be described later, and rotates the third rotating shaft 124. The third gear mechanism 126 comprises a shaft gear 126A, a braking member 126AA, a drive gear 126B, reading gears 126BA and 126BB, and a reading shaft 126C (see Figure 2(D)). Here, the third gear mechanism 126 has almost the same configuration and function as the first gear mechanism 118, so its explanation is omitted. Similarly, the regulating lever 127 has almost the same configuration and function as the regulating lever 119, so its explanation is omitted. 【0026】 In this embodiment, since the main gear assembly 130 rotates clockwise, as shown by the white arrows in Figure 4(A), the first rotation axis 116 and the third rotation axis 124 rotate clockwise, and the second rotation axis 120 rotates counterclockwise. That is, the rotation direction of the first rotation axis 116 is the same as the rotation direction of the third rotation axis 124, and is opposite to the rotation direction of the second rotation axis 120. Furthermore, the first gear mechanism 118, the second gear mechanism 122, and the third gear mechanism 126 are configured such that when the reading axes 118C, 122C, and 126C rotate by 45 degrees, the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 all rotate by 90 degrees. 【0027】 Figures 5(A) to 5(J) show the specific positions of the seven segment sections 114 when the numbers 0 through 9 are displayed in ascending order. Figure 6 shows how many rotations are performed on the first clockwise rotation axis 116, the third rotation axis 124, and the second counterclockwise rotation axis 120 when the number changes. 【0028】 As shown in Figures 2(C), 2(D), and 7, the main gear assembly 130 is rotatably supported on the main frame 104 by coaxially and integrally supporting a first programmed gear body 134 for rotating the first rotating shaft 116, a second programmed gear body 132 for rotating the second rotating shaft 120, and a third programmed gear body 136 for rotating the third rotating shaft 124. Specifically, the main gear assembly 130 is rotatably supported by a fixed shaft 142, which will be described later, fixed to the first frame 106 via a main bearing 128 (shown as a dashed line in Figures 2(C), 2(D), 8(A), and 8(B)) (in Figure 11, the main bearing 128 is positioned at the location indicated by the white arrow). 【0029】 As shown in Figure 7, the first program gear body 134 comprises a first program gear 134A and a first program gear 134B. The second program gear body 132 comprises a second program gear 132A and a second program gear 132B. The third program gear body 136 comprises a third program gear 136A and a third program gear 136B. In other words, the first program gear body 134, the second program gear body 132, and the third program gear body 136 are each composed of a pair of program gears. The pair of reading gears 118BA and 118BB of the first gear mechanism 118 mesh with the pair of program gears (first program gear 134A and first program gear 134B), respectively. Similarly, the pair of reading gears 122BA and 122BB of the second gear mechanism 122 mesh with the pair of program gears (second program gear 132A and second program gear 132B). Also, the pair of reading gears 126BA and 126BB of the third gear mechanism 126 mesh with the pair of program gears (third program gear 136A and third program gear 136B). In this embodiment, the design is based on spur gears with M=1.5 and n=40. 【0030】 As shown in Figure 7, in the main gear assembly 130, the second programmed gear body 132 is located at the very front (i.e., closest to the first frame 106), followed by the first programmed gear body 134, and then the third programmed gear body 136. 【0031】 Spacers 133, 135, and 137 are positioned between the second program gear body 132 and the first program gear body 134, between the first program gear body 134 and the third program gear body 136, and behind the third program gear body 136, respectively. Spacer 133 ensures the smooth rotation of the reading gears 122BA and 122BB that mesh with the second program gear body 132, reducing the possibility of the reading gears 122BA and 122BB meshing with the first program gear body 134 or the third program gear body 136, thereby reducing rotational errors (spacers 135 and 137 have similar effects, so their explanation is omitted). 【0032】 As shown in Figure 4(A), the rotation center of the second rotation shaft 120 is the same as the rotation center of the main gear assembly 130. Here, the direction from the rotation center of the main gear assembly 130 to the rotation center of the reading shaft 126C is shifted clockwise by an angle α (see Figures 4(A) and 7) relative to the direction from the rotation center of the main gear assembly 130 to the rotation center of the reading shaft 122C. Also, the direction from the rotation center of the main gear assembly 130 to the rotation center of the reading shaft 118C is shifted clockwise by an angle β relative to the direction from the rotation center of the main gear assembly 130 to the rotation center of the reading shaft 126C. That is, the starting position of the tooth profile (program data) that defines the same displayed number is determined with a phase shift of angle α between the second program gear body 132 and the third program gear body 136, and with a phase shift of angle β between the first program gear body 134 and the third program gear body 136. In other words, for example, in Figure 8, the second program gear body 132 has tooth profiles that enable the display of the numbers 0 to 9, starting from a position shifted clockwise by an angle γ from the 6 o'clock position and moving counterclockwise. The first program gear body 134 has tooth profiles that enable the display of the numbers 0 to 9, starting from a position shifted clockwise by an angle γ+α+β from the 6 o'clock position and moving counterclockwise. Furthermore, the third program gear body 136 has tooth profiles that enable the display of the numbers 0 to 9, starting from a position shifted clockwise by an angle γ+α from the 6 o'clock position and moving counterclockwise. In this embodiment, for example, angles α, β, and γ are approximately 57 degrees, 51 degrees, and 7 degrees, respectively. 【0033】 In this embodiment, the numbers from 0 to 9 are displayed sequentially as the main gear assembly 130 rotates once. Therefore, each time the number is changed, the main gear assembly 130 is rotated 1 / 10 of a rotation, or 36 degrees. Here, the angle of four teeth is assigned to the angle of 1 / 10 of a rotation (36 degrees) of the main gear assembly 130. Then, the rotation of one tooth angle (9 degrees) of each of the four tooth angles (36 degrees) is configured to allow the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 to rotate by 90 degrees each. As shown in Figure 6, the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 can each rotate a maximum of 270 degrees, meaning that a maximum of three 90-degree rotations are possible. Therefore, the angle of one tooth out of the four can always be set not to rotate. In this embodiment, 0 is used to represent no rotation by 90 degrees, and 1 is used to represent a rotation by 90 degrees, and four 0 and 1 data points are used to represent each number (see Figure 9). In this embodiment, basically, the fourth data point of each of the four data points is set to 0, and the first data point is set to 0 as much as possible, while the second and third data points are adjusted preferentially to avoid interference conditions as shown in Figure 10, so that the timing of the 90-degree rotations is staggered. As a result, in this embodiment, the timing of the 90-degree rotations of the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 when the displayed numbers change in ascending order is defined as shown in Figure 9. The numbers shown in Figure 9 may also be called program data. 【0034】 As shown in Figure 12, the hoisting mechanism 140 comprises a fixed shaft 142, a fixed ratchet mechanism 143, a drive ratchet mechanism 147, a drive shaft 154, and a lever 156, all of which are arranged coaxially. 【0035】 The fixed shaft 142 is mounted on the back of the first frame 106 as shown in Figure 11 and supports the ratchet gear 144. The ratchet gear 144 is a spur gear with teeth that are inclined in the same direction, and n=10. The main bearing 128 is positioned on the outer circumference of the fixed shaft 142 at the positions indicated by the white arrows in Figure 11 and the upper part of Figure 12. 【0036】 The fixed ratchet mechanism 143 comprises the ratchet gear 144 and the ratchet pawl 146 described above. The ratchet pawl 146 is positioned inside the first programmed gear body 134, as shown by the dashed line in Figure 8(D), and comprises a fixed part 146A, a leaf spring part 146B, a rotating part 146C, and a pawl part 146D. The ratchet pawl 146 is attached to the main gear assembly 130 by the fixed part 146A. The leaf spring part 146B is an arc-shaped member and is integrally provided with the fixed part 146A and the rotating part 146C. The rotating part 146C is rotatably attached to the main gear assembly 130. The pawl part 146D is integrally provided with the rotating part 146C, and its tip faces inward. The pawl portion 146D is constantly pressed against the surface of the ratchet gear 144 by the leaf spring portion 146B, regardless of the condition of the inclined teeth surface of the ratchet gear 144. Therefore, in either rotational direction of the ratchet gear 144, the pawl portion 146D engages with the inclined teeth of the ratchet gear 144, allowing the main gear assembly 130 to rotate in only one direction relative to the ratchet gear 144 (in this embodiment, counterclockwise rotation is allowed in Figure 12). 【0037】 The drive ratchet mechanism 147 comprises a ratchet gear 148 and a ratchet pawl 150. The ratchet gear 148 is mounted on the drive shaft 154 and connected to the ratchet gear 144, which is coaxially adjacent to it in the Z direction, by a torsion spring 152. The ratchet gear 148 has almost the same shape as the ratchet gear 144, so its description is omitted. The ratchet pawl 150 is positioned almost inside the spacer 135, as shown by the dashed line in Figure 8(F), and comprises a fixed part 150A, a leaf spring part 150B, a rotating part 150C, and a pawl part 150D. The ratchet pawl 150 also has almost the same shape as the ratchet pawl 146 and is similarly mounted on the main gear assembly 130, so its description is omitted. 【0038】 As shown in Figure 12, the drive shaft 154 is attached to the first advance gear 164, and a lever 156 is attached to its back. The lever 156 is used by the operator to manually change the number. The white arrow in the center of Figure 12 indicates the position where the winding bearing 138, which rotatably supports the drive shaft 154, is positioned relative to the main gear assembly 130 (not shown) (see also Figures 2(C), 2(D), and 8(I)). Furthermore, a shaft bearing 158 is positioned between the first advance gear 164 and the lever 156 (see Figures 2(C) and 2(D)), and the drive shaft 154 is rotatably supported in the hole Hn42 of the third frame 110 (see Figures 1(B) and 2(B)). 【0039】 Now, let's explain the operation of the winding mechanism 140. 【0040】 First, when the lever 156 is rotated at an angle θ, the first lead gear 164, the drive shaft 154, and the ratchet gear 148 rotate simultaneously at the same angle θ (see Figure 2(B)). The angle θ is set to be greater than or equal to the angle of one tooth of the ratchet gear 148 (144) and less than the angle of two teeth. In other words, the angle θ is between 36 degrees and 72 degrees. This angle θ ensures that the ratchet gear 148 rotates by exactly one tooth relative to the ratchet pawl 150 fixed to the main gear assembly 130. The rotation angle of the drive shaft 154 relative to the main gear assembly 130 is then maintained by the ratchet pawl 150 (the angle θ is achieved by restricting the range of movement of the protrusion 164B provided on the first lifting gear 164, which is integrated with the lever 156, with the side portions 108A and 108B provided on the second frame 108, as shown in Figure 2(B)). 【0041】 As a result, the ratchet gear 148 rotates by the angle of one tooth relative to the ratchet gear 144, creating a force in the torsion spring 152 connecting the ratchet gears 144 and 148 that tries to return to its original position. Therefore, as the ratchet gear 148 tries to return to its original rotation angle, the drive shaft 154 rotates, eliminating the angle difference between it and the ratchet gear 144. Here, the drive ratchet mechanism 147 integrates the drive shaft 154 and the main gear assembly 130, so the main gear assembly 130 rotates together with the drive shaft 154 relative to the fixed shaft 142. The fixed ratchet mechanism 143 is provided to prevent over-rotation that may occur when the rotational momentum of the main gear assembly 130 is strong when the drive shaft 154 and the main gear assembly 130 rotate together. 【0042】 In this embodiment, the winding mechanism 140 is used to easily and reliably change the numbers, but the numbers can also be changed by manually turning the main gear assembly 130 precisely 36 degrees at a time. For this reason, the main gear assembly 130 may be in an even simpler form, simply supported by the first frame 106, and the winding mechanism 140 in this embodiment is not necessarily required. 【0043】 The advance mechanism 160, as shown in Figure 12, comprises a plate cam 162, a first advance gear 164, and a second advance gear 166. The plate cam 162 is supported by a spacer 137, as shown in Figure 2(C). In other words, the plate cam 162 is supported by the main gear assembly 130 and rotates integrally with the main gear assembly 130. As shown in Figure 15, the plate cam 162 has a shape in which the outer radius is smallest when the number is 0 and largest when the number is 9, and the outer radius in between increases monotonically, for example, and has one step when going from the maximum outer radius to the minimum outer radius. The first advance gear 164, as shown in Figure 15, is a spur gear in which the tooth profile (tooth profile portion 164A) is formed only on approximately 1 / 4 or less of the portion of a circular spur gear, and has a convex portion 164B on the opposite side of the diameter of the tooth profile portion 164A. The first carry-over gear 164 is supported by a drive shaft 154 that rotates the main gear assembly 130, as shown in Figure 2(C). The second carry-over gear 166 is a spur gear in which a tooth profile (tooth profile portion 166A) is formed only on less than 1 / 4 of the circular spur gear, as shown in Figure 15, and is equipped with a cam follower 166B with a bearing that engages with a plate cam 162 at a position away from its center of rotation. In other words, the second carry-over gear 166 is rotatably supported by the second frame 108 and the third frame 110 and rotates according to the outer shape of the plate cam 162. The carry-over mechanism 160 is used when two or more Karakuri display devices 100 are arranged adjacent to each other. For this reason, in this embodiment, the carry-over mechanism 160 may be removed. In this embodiment, a carry-over occurs when the number changes from 9 to 0, but a borrow occurs when the number changes from 0 to 9. In other words, with digit borrowing, the outer radius is smallest when the plate cam is number 9, and largest when the number is 0. 【0044】 In this embodiment, the seven segment sections 114 are distributed and supported on the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124. By rotating the main gear assembly 130, the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 are rotated, displaying the numbers from 0 to 9 in ascending order. Therefore, not only the changes in the displayed numbers, but also the movements of the first gear mechanism 118, the second gear mechanism 122, and the third gear mechanism 126 that rotate the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 are all generated by the rotation of the main gear assembly 130. In other words, these movements, along with the changes in the numbers, are visible to anyone present. 【0045】 Furthermore, in this embodiment, as shown in Figure 4, the rotation direction of the first rotation axis 116 is clockwise, which is the same direction as the rotation direction of the third rotation axis 124, and is opposite to the counterclockwise rotation direction of the second rotation axis 120. Therefore, the possibility of the seven segment sections 114 interfering with each other can be reduced, and the numbers can be displayed stably. However, this is not limited to this, and the rotation directions of the first rotation axis, second rotation axis, and third rotation axis may be the same or completely different. 【0046】 Furthermore, in this embodiment, a display frame 102 is provided, and the display frame 102 has an opening 102A that allows visibility only of the inside of the segment display area defined by the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124. Therefore, for example, compared to the state without the display frame 102 shown in Figures 5(A) to (J), it is possible to make the numbers easier to see. However, this is not limited to this, and a display frame may not be provided. 【0047】 Furthermore, in this embodiment, the first program gear body 134, the second program gear body 132, and the third program gear body 136 are each composed of pairs of program gears 134A, 134B, 132A, 132B, 136A, and 136B. The first gear mechanism 118, the second gear mechanism 122, and the third gear mechanism 126 are each equipped with pairs of reading gears 118BA, 118BB, 122BA, 122BB, 126BA, and 126BB that mesh with the pairs of program gears 134A, 134B, 132A, 132B, 136A, and 136B, respectively. The reading gears 118BA, 118BB, 122BA, 122BB, 126BA, and 126BB, each consisting of two gears, have four teeth and the same shape, and their phases are 45 degrees apart. This allows for stable transmission of rotational information from the first program gear body 134, the second program gear body 132, and the third program gear body 136 to the first rotating shaft 116, the second rotating shaft 120, and the third rotating shaft 124. However, the reading gears in pairs may each have three or five teeth, or their shapes may not be identical but slightly different. In such cases, it is desirable that their phases be different depending on the number of teeth. For example, when there are three teeth, the phases should be 60 degrees apart, and when there are five teeth, the phases should be 36 degrees apart. In other words, it is desirable that the number of teeth be N (where N is an integer greater than or equal to 3), and that their phases be 360 / 2 / N degrees apart. Of course, the first program gear body, the second program gear body, and the third program gear body may each consist of only one program gear, or they may be composed of three or more program gears as a set. Also, the reading gears do not have to be in pairs, and the number of teeth may differ from that of this embodiment. 【0048】 Furthermore, in this embodiment, the main gear assembly 130 (first program gear body 134, second program gear body 132, and third program gear body 136) is configured to display the numbers from 0 to 9 in ascending order when it rotates once. The angle of four teeth is assigned to the angle of 1 / 10 of a rotation (36 degrees) of the main gear assembly 130. In other words, the angle of four teeth is assigned to the rotation angle of the main gear assembly 130 (first program gear body 134, second program gear body 132, and third program gear body 136) that changes the display of the Karakuri display device 100 by one. Here, the rotation of one tooth angle (9 degrees) of the four tooth angles in the first program gear body 134, second program gear body 132, and third program gear body 136 is configured to allow the first rotation axis 116, second rotation axis 120, and third rotation axis 124 to rotate by 90 degrees, respectively. Therefore, the rotation timing of the first rotation axis 116, the second rotation axis 120, and the third rotation axis 124 in 90-degree increments can be set to a maximum of three out of four timings. In other words, by changing the rotation timing, it is possible to prevent interference (collision) between any of the seven segment sections 114 during the rotation of the first rotation axis 116 and the second rotation axis 120, and between the second rotation axis 120 and the third rotation axis 124. As a result, reliable number changes are possible even when a smaller mechanical display device 100 is realized. 【0049】 Furthermore, the configuration does not have to display the numbers from 0 to 9 one by one in ascending order when the main gear assembly completes one rotation. For example, the configuration could display the numbers from 0 to 9 one by one in ascending order when the main gear assembly rotates only halfway, or it could display the numbers from 5 to 0 one by one in descending order (of course, the numbers do not have to change in order). Also, the first, second, and third rotation axes do not necessarily have to rotate in 90-degree increments. They may rotate in smaller angles, for example, in 45-degree increments. In addition, while the rotation angle of the main gear assembly that changes the display by one was allocated to the angle of four teeth, it may be more than four teeth or less than four teeth depending on the situation. 【0050】 Therefore, in this embodiment, it is possible to provide a highly engaging mechanical display device 100 with an easy-to-understand basic configuration and many moving elements. 【0051】 Although the above embodiments show the configuration when the Karakuri display device 100 is used alone, the present invention is not limited thereto. For example, as shown in the second embodiment in Figures 13, 14, and 15, two Karakuri display devices 100 and 200 may be placed adjacent to each other and used as a two-digit display device. 【0052】 In this embodiment, the Karakuri display device 100 displays the first digit, and the Karakuri display device 200 displays the second digit. The only difference between the Karakuri display device 100 and the Karakuri display device 200 is the presence or absence of a lever; everything else is identical. 【0053】 As shown in Figure 15, when two (or more) Karakuri display devices 100 and 200 are placed adjacent to each other, the configuration is such that the first advance gear 264 of one Karakuri display device 200 meshes with the second advance gear 166 of the other Karakuri display device 100. Therefore, when the main gear assembly 130 of the other Karakuri display device 100 is rotated once, the main gear assembly 230 is rotated by 1 / 10 of a turn at the position of the step in the plate cam 162 so that the display of the one Karakuri display device 200 changes. Note that in Figure 15, the first advance gear 164 does not affect the movement of the second advance gear 166, so it is shown with a dashed line. The dashed lines of the second advance gear 166 and the first advance gear 264 show the respective rotational states that realize the angle θ when the plate cam 162 completes one rotation. In this embodiment, the rotation angle θ of the protrusion 264B of the first advance gear 264 is achieved by adjusting the shape of the plate cam 162 and the meshing conditions between the first advance gear 264 (164) and the second advance gear 166. 【0054】 In this embodiment, the first advance gear 264 and the second advance gear 166 are directly meshed, but the present invention is not limited to this. For example, any configuration in which one or more other gears are combined so that the first advance gear 264 rotates in accordance with the rotation angle of the second advance gear 166 is acceptable. 【0055】 Furthermore, in this embodiment, the numbers 0 through 9 were displayed in order only once when the main gear components 130 and 230 were rotated once, but the present invention is not limited to this. For example, when the main gear components are rotated once, the numbers 0 through 9 may be repeated in order two or three times. That is, the plate cam may have one or more steps where it moves from the maximum outer radius to the minimum outer radius. Also, the repetition of the numbers may be only 0 and 1, or 0 through 4, 0 through 5, etc. That is, when the main gear component of the other Karakuri display device is rotated, the main gear component may be configured to rotate in such a way that the display of the other Karakuri display device changes at each step position of the plate cam. 【0056】 Furthermore, while the above embodiment allowed for the display of numbers from 0 to 9 using seven segments, the present invention is not limited to this. For example, the seven segments may be used to display multiple numbers from 0 to 9 (see Figure 13). 【0057】 Furthermore, while the above embodiment described the mechanical display device as displaying numbers, the present invention is not limited to this. The mechanical display device may be used to display multiple English letters, such as A, B, C, H, etc. In addition, when the mechanical display device is capable of displaying either multiple numbers or multiple English letters, it may also be capable of displaying symbols or the like. 【0058】 Furthermore, in the above embodiment, as shown in Figure 1(A), the first rotation axis 116 and the third rotation axis 124 were arranged on the left side of the page, and the second rotation axis 120 was arranged on the right side of the page. However, the present invention is not limited to this. For example, as shown in the third embodiment in Figure 16, the first rotation axis 316 and the third rotation axis 324 may be arranged on the right side of the page, and the second rotation axis 320 may be arranged on the left side of the page. In this case, it is possible to display multiple numbers while also being able to display multiple English letters such as E and F. 【0059】 In the above embodiment, the seven segment sections were assumed to be arranged at angles of 90 degrees or 180 degrees to each other, but the present invention is not limited to this. For example, as shown in the fourth embodiment in Figure 17, some of the seven segment sections may be arranged at other angles, such as 135 degrees to each other. Even in such a configuration, the fourth segment section 414E is arranged between the first segment section 414A and the second segment section 414B, and the fifth segment section 414G is arranged between the second segment section 414B and the third segment section 414C, and it is possible to display English letters such as E, F, and P, and this is included in the present invention. 【0060】 In the above embodiment, the numbers were displayed in ascending order on the mechanical display device, but the present invention is not limited to this. For example, the numbers may be displayed in descending order on the mechanical display device. Alternatively, even if not all numbers are displayed, only a few numbers may be displayed. 【0061】 In the above embodiment, the digits on the mechanical display device were changed manually, but the present invention is not limited to this. For example, a spring, battery, motor, pendulum, oscillator, etc., may be combined and used as part of a clock or measuring timer. In that case, the winding mechanism of the above embodiment may be used as is to rotate the drive shaft by an angle θ at intervals of, for example, one second, or the drive shaft may be directly attached to the main gear assembly to rotate the drive shaft precisely at intervals of, for example, one second. 【0062】 In this case, the device may be a mechanical display device capable of displaying the numbers 0 through 5 in seven segments. For example, as shown in the second embodiment, it is also possible to configure a timer that advances in increments of 60 minutes by arranging two or more mechanical display devices adjacent to each other. [Industrial applicability] 【0063】 The present invention can be widely applied to highly decorative mechanical display devices, particularly those used for interior decoration or toys.
