Description

  The present invention relates to a music box apparatus for performing a performance by rotating a star wheel engaged with the hole by moving a seat provided with a through hole or the like at a predetermined position, thereby playing a vibration valve.

  Conventionally, as a music box device that plays music by playing vibration valves with different scales at a predetermined timing, a cylinder-type music box device in which pins that engage with the vibration valves are provided at a predetermined pitch on the outer peripheral surface of the cylinder is known. It is. Since such a cylinder-type music box device cannot generally change a cylinder, only a fixed tune is played.

  On the other hand, instead of the configuration in which the vibration valve is directly flipped by the pin of the cylinder, a sheet provided with a through hole at a predetermined position, and a star wheel having a plurality of claws on the outer peripheral surface and held idle on the shaft, Also known is a music box device in which one of the star wheels is engaged with the through hole by moving the seat and the star wheel is rotated to play the vibration valve with the other claws of the star wheel. It has been. For example, Patent Document 1 discloses a tape-type music box device configured to use a long tape as a sheet and feed the tape from a feed-side roll to a receiving-side roll. Patent Document 2 discloses a disc-type music box using a disc-like disc as a sheet. According to such a music box device, it is possible to play various tunes by exchanging tapes and disks.

  By the way, the position of the through hole provided in the tape or disk changes if the music changes. For this reason, at the end of a performance on a certain disk, when the nail of one star wheel is engaged with the through hole in a state of being directly above, another disk does not have a through hole at this position. It is assumed that In such a case, there is a possibility that the star wheel claw facing upwards strongly contacts the replaced disc, and the disc may not be rotated smoothly or the disc may be damaged.

  In order to cope with such a problem, in Patent Document 3, a motor is used as a driving means for rotating a disk, and the motor is rotated forward to perform a performance. On the other hand, when a disk change is detected by a predetermined switch, the power is turned on. At that time, the motor is rotated in the reverse direction, and the shaft holding the star wheel so as to be idle is also rotated in the direction opposite to the performance state. That is, with the reverse rotation of the shaft, the star wheel idles in a state where the claw is in contact with the vibration valve and the rotational direction of the star wheel is aligned. This makes it possible to prevent the above-described problems during disk replacement.

  By the way, in the music box apparatus of patent document 3, there is a restriction that various switches must be used in addition to the motor. That is, there is a problem in terms of usability, such as an expensive device and use only in a place where a power source can be secured.

  An object of the present invention is to solve such problems, and it is possible to perform various songs by exchanging the seats, and to effectively solve the problems associated with the interference between the star wheel and the seats. It is another object of the present invention to provide a novel music box device that can prevent the above-mentioned problem and can prevent the malfunction without using a motor or the like.

In the present invention, a seat having a performance engaging portion and moved by a driving means, and a shaft which is disposed opposite to the sheet and has two or more claw portions on an outer peripheral surface and which is rotated by the driving means are held idle. And a vibration valve disposed adjacent to the star wheel, and the performance engaging portion is linked to one of the claw portions as the seat is moved by the driving means. In the music box device that rotates and plays the other pawl part by playing the vibration valve,
Switching means for switching the driving force of the driving means between a transmission state transmitted to the seat and the shaft and a non-transmission state not transmitted to the seat and the shaft;
Sheet feeding means capable of moving the sheet in the feeding direction or the rewinding direction in the non-transmitting state;
The sheet can be rotated by the sheet feeding means, and when the sheet feeding means moves the sheet in the feeding direction, the sheet feeding means rotates in the first direction and moves in the first direction, while the sheet feeding means rotates the sheet in the unwinding direction. The first relay gear includes a moving gear that rotates in the reverse direction and moves in the second direction when moved to the first direction, and a first relay gear that meshes with the moving gear when the moving gear moves in the first direction. A first relay gear path for rotating the shaft in accordance with rotation, and a second relay gear that meshes with the moving gear when the moving gear moves in the second direction. And a second relay gear path for rotating the shaft, and the number of gears constituting the first relay gear path differs from the number of gears constituting the second relay gear path by an odd number. And a reverse turning means for rotating the shaft in the direction opposite to the rotation direction by the driving means regardless of whether the sheet feeding means moves the sheet in the feeding direction or the rewinding direction. .

  Here, the switching means has a switching gear movable between a lower position in the transmission state and an upper position in the non-transmission state, and a hook engaged with the shaft portion of the switching gear, A slide member for moving the switching gear to the upper position by moving the switching gear to the lower position by moving the hook away from the shaft portion, and engaging the hook with the shaft portion by moving the hook closer to the shaft portion; Are preferably provided.

The sheet has a spiral plate shape,
The sheet feeding means has a toothed portion that meshes with the moving gear and is connected to the end of the sheet, or a receiving side that has a toothed portion that meshes with the moving gear and is connected to the leading end of the sheet. Equipped with a turntable,
The switching means allows the movement gear to move in the first direction or the second direction in the non-transmission state, while the movement gear meshes with the second relay gear in the transmission state. It is preferable to have a restraining lever.

  In the music box device according to the present invention, when the driving force transmitted from the driving means to the shaft holding the seat and the star wheel so as to be idle is switched to a non-transmitting state by the switching means, and when the sheet is moved by the sheet feeding means, The shaft is configured to rotate in the reverse direction. In other words, the claw of the star wheel comes into contact with the vibration valve with the reverse rotation of the shaft, and the star wheel idles with respect to the shaft in this state, so that the rotational position of the star wheel does not interfere with the seat. Can be aligned. Further, since the driving means is not used for aligning the rotational direction positions of the star wheels, it is possible to prevent problems without using a motor or the like. Further, since the sheet can be moved in the feeding direction or the rewinding direction by the sheet feeding means, it is possible to perform the music from the place where the user wants to listen. In addition, the shaft can be rotated in the reverse direction regardless of whether the sheet is moved in the feeding direction or the rewinding direction by the sheet feeding means. Since the rotation direction position can be aligned, it is excellent in operability.

  When a switching gear that can be moved between the lower position in the transmission state and the upper position in the non-transmission state is provided as the switching means, a mechanism that performs the performance by manually rotating the handle as a driving means is adopted. Even if the handle is rotated in the opposite direction to the performance direction, the movement of the switching gear can be in a non-transmission state in which the driving force of the driving means is not transmitted to the seat or the like. Can be prevented. Further, by using a slide member having a hook engaged with the shaft portion of the switching gear, the transmission state and the non-transmission state can be switched by the movement of the slide member, so that the operability is improved.

  The sheet may be a tape or a disk as in the past, but it is preferable to use a spiral plate-like sheet. When such a spiral plate-like sheet is used, it is possible to perform for a longer time than the disc. Also, when using tape-like sheets, the performance time can be lengthened. However, since the tape-like sheets must be wound around the feeding side roll and the receiving side roll, the roll wound when the performance time becomes longer. As a result, the thickness of the apparatus increases. On the other hand, in the spiral plate-like sheet, the unplayed part and the played end part can be overlapped to form a layer, so that the thickness of the apparatus can be suppressed.

  Further, the sheet feeding means has a toothed portion that meshes with the moving gear and is connected to the end portion of the sheet, or a receiving side rotation that has a toothed portion that meshes with the moving gear and is connected to the leading end portion of the sheet. When the switching means has a lever that is restrained in a state where the moving gear meshes with a predetermined gear in the transmission state, the switching means rotates together with the spiral plate-like sheet and the receiving side rotation. The board can be rotated. That is, even a thin sheet can be stably rotated.

  Further, the shaft 209 is provided with an eighth gear 215 as shown in FIGS. 6A and 8B, and the eighth gear 215 rotates integrally with the shaft 209.

  Incidentally, the music box main body 2 includes a slide member 216 shown in FIGS. 3 and 7 to 12. When the slide member 216 moves in the direction shown in FIGS. 7 to 9, the seat 13 can be rotated by operating the handle 201, and a musical performance can be performed. When it moves in the direction shown, the feed-side rotating disk 5 can be rotated by operating the knob 9 to rotate the sheet 13 in the feeding direction or the rewinding direction. Although a detailed description of the configuration is omitted, the slide member 216 is moved when moved in the direction shown in FIGS. 7 to 9 and moved when moved in the direction shown in FIGS. At the end position, it is fixedly held so as not to move carelessly. Here, as shown in FIG. 7C, the slide member 216 has a lever 217 swingably provided around the swing center C1 and a connecting arm provided swingably around the swing center C2. 218 is connected. A swing shaft 219 that swings with the connecting arm 218 is provided on the axis of the swing center C2, and the swing shaft 219 is provided with an arm 220 shown in FIG. 8B. The arm 220 also swings with the connecting arm 218.

  The arm 220 includes a drive shaft 221 rotatably held by the arm 220, a shaft gear 222 that meshes with the eighth gear 215 and rotates integrally with the drive shaft 221 as shown in FIG. 8B. A driving roller 223 that rotates integrally with the drive shaft 221 and feeds the sheet 13 while sandwiching the sheet 13 with the spacer 2d as shown in FIG. 8C is provided. The arm 220 includes a pressing roller 224 (see FIG. 6A) that is attached to the drive shaft 221 and moves the sheet 13 toward the spacer 2d.

  In the moving gear 214 described above, as shown in FIGS. 6A and 7C, the lever 217 is connected to the side of the lever 217 integrally with the moving gear 214, and when the lever 217 swings, A disk-shaped contact portion 225 that contacts and moves the moving gear 214 in the second direction is provided.

  Further, the slide member 216 described above is provided with a hook 226 having a claw shape as shown in FIGS. 6 (a) and 7 (a). The hook 226 is provided integrally with the slide member 216 at a position where it engages with the shaft portion 204 of the switching gear 203 (the large-diameter columnar portion of the shaft portion 204).

  The swing shaft 219 includes a swing shaft gear 227 as shown in FIG. The swing shaft gear 227 meshes with the first switching gear 228, and the first switching gear 228 is integrally provided at one end of the switching shaft 229. A second switching gear 230 is provided at the other end of the switching shaft 229. Here, as shown in FIG. 9B, the second switching gear 230 meshes with the rack of the knob shaft portion 9c.

  In order to perform with the music box apparatus 1 having such a configuration, the slide member 216 is moved in the direction of the arrow (left side) shown in FIG. Thereby, as will be described below, the driving force of the driving means 2c is transmitted to the seat 13 and the shaft 209. Here, the switching gear 203 that is disengaged from the hook 226 moves downward due to its own weight (see FIG. 7A). The second gear 207 that is integrally connected to the switching gear 203 moves to the lower position together with the switching gear 203 and is in a state of meshing with the third gear 208 as shown in FIG. . Then, when the handle 201 is rotated in the direction of FIG. 7A, the first gear 202 and the switching gear 203 are also rotated, and accordingly, the second gear 207 is rotated as shown in FIG. The shaft 209 also rotates together with the gear 208. Then, as shown in FIG. 8A, the fourth gear 210 also rotates with the rotation of the shaft 209, whereby the seventh gear 213 also rotates. Incidentally, a lever 217 is connected to the slide member 216 as shown in FIG. Then, when the slide member 216 moves in the direction of the arrow (left side), the lever 217 swings as shown in FIG. 7C, whereby the lever 217 is pressed against the contact portion 225, and the moving gear 214 is moved. It is restrained by moving to the right side (second direction) in FIG. At this position, as shown in FIG. 8A, the moving gear 214 is not meshed with the sixth gear 212 but meshed with the teeth of the seventh gear 213 and the feed-side rotating disk 5. . Therefore, when the seventh gear 213 rotates, the feed-side rotating disk 5 also rotates (rotates counterclockwise around the central axis O shown in FIG. 2 in plan view) via the moving gear 214. At the same time, since the receiving-side rotating disk 6 also rotates through the synchronization gear 7, the seat 13 connected to these also rotates. As described above, in the present embodiment, since the feeding-side rotating disk 5 and the receiving-side rotating disk 6 rotate in synchronization, it is possible to stably rotate the sheet 13 without applying a load. it can.

  When the seat 13 rotates, as shown in FIG. 4, the upper portion (unplayed portion) of the spiral plate-like seat 13 placed on the upper partition plate 3 passes above the star wheel 2a through the hole 3a. To do. Accordingly, the performance engaging portion 13a is linked to one claw portion 2a1 of the star wheel 2a to rotate the star wheel 2a, and the other claw portion 2a1 can play a sound by playing the vibration valve 2b. . Since the sheet 13 has a spiral plate shape and a long overall length, it can be played for a long time. And the lower part (performance completion part) of the sheet | seat 13 which passed the star wheel 2a is mounted below the lower partition plate 4 through the hole 4a. Thus, the sheet 13 can overlap the unplayed portion and the performance end portion so as to form a layer above the upper partition plate 3 and below the lower partition plate 4, thereby reducing the thickness of the music box device 1. It becomes possible.

  Further, in this state, as shown in FIG. 8B, the arm 220 connected to the swing shaft 219 also swings counterclockwise, so that the shaft gear 222 meshes with the eighth gear 215. For this reason, the rotational force of the handle 201 is transmitted to the drive shaft 221 via the shaft gear 222, and the drive roller 223 is also rotated as shown in FIG. Thereby, since the sheet 13 sandwiched between the spacer 2d and the driving roller 223 is sent out by both the spacer 2d and the driving roller 223, the sheet 13 can be stably rotated. Further, as shown in FIGS. 3 and 6A, the drive shaft 221 is provided with a plurality of press rollers 224, and the sheet 13 has a spacer in the entire radial direction by the drive rollers 223 and the press rollers 224. It is approaching toward 2d. That is, since the sheet 13 is also brought close to the star wheel 2a adjacent to the spacer 2d, the claw portion 2a1 provided on the star wheel 2a is securely connected to the performance engaging portion 13a provided on the sheet 13 as shown in FIG. Because it can be engaged with each other, it is possible to perform as expected.

  Further, in this state, as shown in FIG. 9A, the swinging shaft gear 227 connected to the swinging shaft 219 swings counterclockwise and engages with the swinging shaft gear 227. 6 rotates clockwise, the second switching gear 230 connected to the first switching gear 228 via the switching shaft 229 also rotates clockwise as shown in FIG. 6B. Here, since the knob 9 has the knob shaft portion 9c having a rack that meshes with the second switching gear 230, the knob 9 rises to the upper standby position.

  When the handle 201 is rotated in the reverse direction (the direction opposite to the direction shown in FIG. 7A) in such a playable state, the switching gear 203 and the second gear 207 are moved with respect to the first gear 202. Is moved upward, whereby the second gear 207 is separated from the third gear 208, so that the driving force of the handle 201 is not transmitted to the seat 13 or the like. That is, even if the handle 201 is reversely rotated, the music box device 1 is not damaged.

  By the way, in the music box apparatus 1 of the present embodiment, the driving force of the driving means 2c is not transmitted to the seat 13 and the shaft 209 by moving the slide member 216 in the direction of the arrow (right side) shown in FIG. By switching to the transmission state, the sheet 13 can be rotated in the feeding direction or the rewinding direction. In this state, the hook 226 approaches the switching gear 203 and engages with the shaft portion 204, and the switching gear 203 moves upward. As a result, the second gear 207 that is integrally connected to the switching gear 203 moves to the upper position together with the switching gear 203 so that it does not mesh with the third gear 208 as shown in FIG. Become. For this reason, even if the handle 201 is rotated, the driving force is not transmitted to the seat 13 and the shaft 209.

  In this state, as shown in FIG. 11B, the arm 220 connected to the swing shaft 219 also rotates clockwise, so that the shaft gear 222 is also separated from the eighth gear 215 and shown in FIG. 11C. Thus, the driving roller 223 is also separated from the spacer 2d. That is, the sheet 13 is not sandwiched between the driving roller 223, the pressing roller 224, and the spacer 2d. Further, in this state, as shown in FIG. 10C, the restraint of the contact portion 225 by the lever 217 is released, so that the moving gear 214 is moved in the direction (first direction) shown in FIG. Is also movable in the direction (second direction) shown in FIG. In this state, as shown in FIG. 12A, the swing shaft gear 227 connected to the swing shaft 219 rotates clockwise, and the first switching gear 228 rotates counterclockwise. As shown in FIG. 12B, the second switching gear 230 also rotates counterclockwise. As a result, the knob 9 is moved downward via the knob shaft portion 9 c, and a tooth portion (not shown) provided on the lower surface of the outer edge of the knob 9 is a tooth portion on the radially inner upper surface of the feed-side rotating disk 5. Therefore, the sheet 13 can be fast-forwarded or rewound at a high speed as the knob 9 rotates.

  Here, when the knob 9 is rotated to move the feed-side rotating disk 5 in the direction of the arrow (left side) shown in FIG. 11 (a-1), the moving gear 214 is also moved to the left side (first direction). And further meshes with the sixth gear 212 and rotates. That is, as shown in FIG. 11 (a-1), when the feed-side rotating disk 5 is moved in the direction in which the sheet 13 is fed out, the moving gear 214 meshes with the sixth gear 212 and rotates counterclockwise. The fourth gear 210 rotates clockwise through the fifth gear 211, and the shaft 209 also rotates clockwise. Accordingly, the star wheel 2a held on the shaft 209 so as to be able to idle is also rotated clockwise, and stops at a position where the claw portion 2a1 contacts the upper surface of the vibration valve 2b as shown in FIG. As a result, the rotational direction positions of all the star wheels 2a can be aligned. It is possible to prevent a problem that the claw portion 2a1 hits the sheet 13 strongly.

  On the other hand, when the feed-side rotating disk 5 is moved in the direction of the arrow (right side) shown in FIG. 11 (a-2), the moving gear 214 is also moved to the right side (second direction), and the seventh gear 213 is further moved. Meshes with and rotates. That is, as shown in FIG. 11 (a-2), when the feed-side rotating disk 5 is moved in the direction of rewinding the sheet 13, the moving gear 214 meshes with the seventh gear 213 and rotates clockwise. Since the fourth gear 210 rotates clockwise and the shaft 209 also rotates clockwise, the rotational direction positions of all the star wheels 2a can be aligned. In this way, the feed-side rotating disk 5 can rotate the shaft 209 in the same direction to align the rotational direction position of the star wheel 2a regardless of whether the sheet 13 is moved in the direction of feeding out or moved in the direction of rewinding. it can.

  The music box apparatus of the present invention is not limited to the embodiments described so far, and includes various modifications. For example, in the figure used for description of the present embodiment, each component member is shown in a simplified manner, but is not limited to this shape. In the spiral plate-like sheet in the above-described embodiment, the part placed on the upper partition plate is an unplayed part, and it is sent out to perform a song. It is configured to be placed below the partition plate. That is, in the present embodiment, the upper rotating disk to which the moving gear is connected is the feeding-side rotating disk that sends out the sheet, and the lower rotating disk is the receiving-side rotating disk. On the other hand, the sheet is configured such that the portion placed below the lower partition plate is sent out and placed on the upper partition plate, and the sheet is received by the upper rotating plate to which the moving gear is connected. Good (the upper rotating disk may function as a receiving rotating disk). In the above-described embodiment, a handle that is turned by hand as a driving means for rotating the seat 13 is used so that the performance is performed while the handle is being moved. The performance may be performed even when the handle is not moved. Although there are restrictions on the power source and the like, it does not prevent the motor from being used as the driving means. Further, a long tape may be used as the sheet, or a disk-shaped disk may be used.
