DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a music box device. More specifically, the present invention relates to a music box device capable of changing a musical piece to be played.

[0002]

2. Description of the Related Art Conventionally, there is a so-called tape type music box device as a music box device capable of exchanging musical pieces to be played. This tape-type music box device is for playing while passing a tape inside the music box body. A large number of musical note holes are punched in the tape, and when passing through the music box body, the corresponding claw gear is rotated in each musical note hole to play the corresponding diaphragm to play a melody according to the arrangement of the musical note holes. . In the case of this music box device, the musical piece to be played can be changed by exchanging the tape.

On the other hand, as a music box device capable of exchanging the musical pieces to be played and capable of playing for a long period of time, it has been practically used.
There is one disclosed in Japanese Patent Publication No. 7-84592 (Jitsuko Sho 57-60072). In this music box device, a large number of projections for flipping the vibration valve are formed on an annular endless belt, and each projection directly plays each vibration valve of the music box body to perform a performance. The ring-shaped endless belt is housed in the cassette, and the music box music can be changed by exchanging the endless belt together with the cassette.

[0004]

However, in the above-mentioned tape type music box device, since the tape having the musical note holes is used as it is, that is, the tape is extended, the handling becomes inconvenient. For this reason, the tape could not be lengthened, and a song with a long playing time could not be changed to a music box.

On the other hand, in the music box device of the type in which the annular belt is exchanged for each cassette, the playing time is merely lengthened by repeatedly playing the same song, and the length of the song itself is short. Further, there is a problem that the cassette becomes large in size when trying to make a song having a long playing time. In addition, it is difficult to directly repel each vibration valve with the protrusions formed on the flexible endless belt, the life of the belt is short, and a large number of protrusions are formed on the endless belt. That is expensive.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a music box device capable of playing a long piece of music and exchanging the music pieces to be played. Another object of the present invention is to provide a music box device in which a tape having musical note holes can be easily handled.

In order to achieve such an object, the present invention is a music box apparatus for performing a performance while passing a tape having a large number of musical note holes through the music box body, and a casing for accommodating the music box body and the tape in a roll shape. A roll of tape, which is housed in the casing and is detachably arranged on one side of the music box body, and a tape roll, which is housed inside the casing and arranged on the other side of the music box body, extends from the tape roll to open the music box body. Winding means for winding the tape passing through in a roll shape, rotational force generating means for giving a tape propulsion force to the music box body, and guiding part of the tape propulsion force to the winding means to interlock the winding means with the music box body. It is configured to include a rotational force transmission means for causing the rotation force.

Therefore, when the torque generating means applies a tape driving force to the music box body, the tape extending from the tape roll begins to pass through the music box body, and the music box performance is started. Since a part of the tape driving force is also transmitted to the winding means by the rotational force transmitting means, the tape passing through the music box body is wound up by the winding means rotating in conjunction with the music box body. That is, the tape is wound into a roll while playing the music box.

In this case, it is desirable that the torque generating means should manually generate the tape driving force. Therefore, in this case, it is not necessary to provide an extra installation space in the casing, and the tape propulsive force applied to the music box body is not unintentionally interrupted during the performance of a long music box tune.

Further, in this case, it is preferable that the rotational force transmitting means is a belt wound around the rotating body of the music box body and the rotating body of the winding means. Therefore, in this case, when a rotation difference occurs between the rotating body of the music box body and the rotating body of the winding means, the belt itself stretches or slips, and the rotation difference between the rotating bodies is absorbed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The configuration of the present invention will be described below in detail based on the best mode shown in the drawings.

1 to 4 show an embodiment of a music box device according to the present invention. This music box device 1 is for performing a performance while passing a tape 2 having a large number of musical note holes 2a through the music box main body 3, and a casing 4, a music box main body 3, and a tape roll 5 formed by winding the tape 2 in a roll shape. , A winding means 6 for winding the tape 2 passing through the music box body 3, a rotational force generating means 7 for generating a tape driving force, and a rotational force transmitting means 8 for interlocking the winding means 6 with the music box body 3. Has been done.

The tape 2 is made of paper, for example. The front and rear ends of the tape 2 (only the front side is shown in FIG. 1)
Is a lead portion 2b having a narrow width, for example. Thin plates 29 are fixed to each lead portion 2b in a laminated manner, and the lead portions 2b are reinforced. Each thin plate 29 is formed of, for example, an aluminum material. When the thin plate 29 is formed using an aluminum material, the thin plate 2
9 can be easily manufactured.

Inside the box-shaped casing 4, upper and lower accommodating spaces 10 and 11 are provided by a partition plate 9. The music box body 3, the tape roll 5, the winding means 6 and the like are arranged in the upper space 10, and when the lid 4a of the casing 4 is opened, the music box body 3 and the like are exposed. On the other hand, the lower space 11 is a storage space, and by opening the door 4b of the casing 4, it is possible to store the replacement tape roll 5 and a handle described later.

The music box body 3 is mounted on a base 13 fixed to the upper surface of the partition plate 9. The music box body 3 has the same structure as the music box body of the conventional tape-type music box device. Therefore, in this specification, the music box body 3 will be described only briefly. That is, the music box body 3 is provided with a plurality of rollers 14 for continuously feeding the inserted tape 2 as shown in FIGS. When the tape 2 passes through the music box body 3, the note hole 2 of the tape 2
The claw gear 15 having the claw 15a hooked on a rotates and flips the diaphragm 30. Since the tape 2 is provided with a large number of musical note holes 2a, a plurality of claw gears 15 sequentially play the corresponding diaphragms 30 to produce a melody.

The tape roll 5 is formed by winding the tape 2 around a cylindrical core member 16 in a roll shape. The tape roll 5 is housed in the upper space 10 in the casing 4 and arranged on one side of the music box body 3. There is. The core member 16 has a pair of flanges 16a and 16a, and prevents a deviation when the tape 2 is wound. Shafts 16b and 16c are formed on both end surfaces of the core member 16. The shaft 16b is the bearing 1
7, and the shaft 16c is rotatably supported by the casing 4 via a rotary shaft 18. Axis 16
c is, for example, a serration shaft, and the shaft 16c and the rotary shaft 18 are serration-coupled and rotate integrally. The tip of the rotary shaft 18 projects to the outside of the casing 4.

Further, at least one of the shafts 16b and 16c, for example, the shaft 16b, can be retracted into the core member 16. That is, as shown in FIG. 7, the shaft 16b
Is inserted into a hole 16d provided in the end surface of the core member 16 and is pushed out by the spring force of the spring 19. The shafts 16b, 16
When the entire core member 16 is displaced toward the bearing portion 17 from the state in which c is supported, the shaft 16b which is in contact with the bearing portion 17 is retracted into the hole 16d while compressing and compressing the spring 19. Therefore, the shaft 16c on the opposite side is rotated by the rotary shaft 18
Then, the core member 16 can be removed from the casing 4. As a result, the tape roll 5 is rotatably and detachably attached to the casing 4 and accommodated in the upper space 10.

The core member 16 is formed with a slit (not shown) similar to the slit 6d of the winding means 6 described later. The tape 2 is wound into a roll by the core member 16 after inserting the lead portion on the rear end side into the slit.

The winding means 6 is, for example, a hollow cylindrical body and is housed in the upper space 10 in the casing 4 and is on the other side of the music box body 3, that is, on the opposite side of the tape roll 5 with the music box body 3 interposed therebetween. It is located in. The winding means 6 has a pair of flanges 6 a like the core member 16. Shafts 6b and 6c are formed on both end surfaces of the winding means 6. Each shaft 6b is rotatably supported by the casing 4 via a bearing portion 20, and the shaft 6c is rotatably supported by a casing 4 via a rotary shaft 21. The shaft 6c is, for example, a serration shaft, and the shaft 6c and the rotating shaft 21 are serration-coupled and rotate integrally.

A tape insertion slit 6d is formed along the longitudinal direction on the peripheral surface of the winding means 6.
The leading end portion 2b of the tape 2 that extends from the tape roll 5 and passes through the music box body 3 is inserted into the tape insertion slit (hereinafter referred to as slit) 6d. When the winding means 6 is rotated with the lead portion 2b inserted in the slit 6d, the tape 2 is wound into a roll by the winding means 6.

The rotating force generating means 7 is, for example, a handle which is manually rotated. A handle (hereinafter, referred to as a handle 7) that is the rotational force generating means 7 is detachably connected to a tip portion of a shaft 22 that projects to the outside of the casing 4. A pin 23 is fixed to the tip of the shaft 22 in a penetrating state to rotate the handle 7 and the shaft 22 integrally. The rotation of the shaft 22 is transmitted to each roller 14 of the music box body 3 via the reduction gear mechanism 24, as shown in detail in FIG. That is, the rotational force of the handle 7 is manually generated, and this rotational force is applied to each roller 14 of the music box body 3 as a tape driving force.

When the tape 2 is rewound after the music box is played, the handle 7 is connected to the rotary shaft 18. A pin 31 is fixed in a penetrating state near the tip of the rotary shaft 18, and the rotary shaft 18 and the handle 7 rotate integrally.

The rotating force transmitting means 8 is a first pulley 25 which is a rotating body fixed to the shaft 22, a second pulley 26 which is a rotating body fixed to the rotating shaft 21, and these pulleys 2
The belt 27 is wound around 5, 26. The first pulley 25 has a smaller diameter than the second pulley 26, and the belt 27 reduces the rotation of the shaft 22 while decelerating the rotation of the shaft 2.
Transmit to 1. As a result, a part of the tape driving force applied from the handle 7 to the music box body 3 is partially absorbed by the rotary shaft 21.
The winding means 6 is guided by the winding means 6 which rotates together with the winding means 6, and the winding means 6 interlocks with the music box body 3.

The belt 27 is, for example, a rubber belt.
Therefore, the belt 27 frictionally engages with the pulleys 25 and 26, and the rotational force is satisfactorily transmitted. On the other hand, the pulleys 25,
When there is a difference in rotation between the belts 26, the belt 27 extends or slips on the pulleys 25 and 26, preventing damage to the tape 2, the music box body 3, and the like.

Reference numeral 28 in FIG. 1 is a rewinding guide that covers the irregularities of the music box body 3.

Next, the operation of the music box device 1 will be described.

First, the handle 7 is connected to the shaft 22, and the tape roll 5 of the desired music piece is arranged on one side of the music box body 3. Next, the tip of the tape 2 is pulled out from the tape roll 5 and inserted into the music box body 3, and the handle 7 is turned to feed the tape 2 to the winding means 6 side while generating a tape propulsion force on each roller 14. The lead portion 2b on the front end side of the tape 2 that has passed through the music box body 3 is inserted into the slit 6d of the winding means 6. Lead part 2b
Is reinforced by the thin plate 29, so that it can be easily inserted into the slit 6d and the frictional force generated between the lead portion 2b and the winding means 6 can be increased.

In this state, the handle 7 is further rotated to wind the tape 2 sent by each roller 14 by the winding means 6 to a certain extent to prevent the tape 2 from coming off the winding means 6. This completes the performance preparation.

Although the music box performance can be performed with the lid 4a closed, the volume of the music box performance can be increased by performing the music box performance with the lid 4a opened.

When the handle 7 is further rotated further, the position where the musical note hole 2a of the tape 2 is punched begins to reach the music box body 3, and the claw gears 15 successively play the vibrating plate 30 to start the performance. . The rotational force of the handle 7 is transmitted to the music box body 3 as a tape driving force, and is also transmitted to the winding means 6 via the rotational force transmission means 8.
The belt 27 of the rotational force transmitting means 8 rotates the winding means 6 in conjunction with the music box body 3, so that the tape 2 is smoothly taken up by the winding means 6 after passing through the music box body 3. Thereby, the long tape 2 can be wound while playing the music box. Further, since the tape 2 made of paper is used, wear of the claws of each claw gear 15 is small.

As the music box performance progresses and the winding amount of the tape 2 by the winding means 6 increases, the apparent thickness of the portion of the winding means 6 to be actually wound is increased by the thickness of the wound tape 2. Becomes thicker. Therefore, the length of the tape 2 which can be wound by one rotation of the winding means 6 becomes long, and a deviation occurs between the winding amount and the feeding amount of the tape 2 by the music box body 3. However, the first pulley 25 connected to the music box body 3 side and the second pulley 26 connected to the winding means 6 side are connected by a belt 27, and the belt 27 can extend and each belt 27 can be extended. Since it is possible to slide with respect to the pulleys 25 and 26, smooth music box performance can be continued while absorbing the deviation. Similarly, even when the tape 2 is caught on the music box body 3, the belt 27 absorbs the difference in rotation between the pulleys 25 and 26 and prevents the tape 2 and the music box body 3 from being damaged.

When the music box performance is completed, the lead portion on the rear end side of the tape 2 comes off from the slit provided in the core member 6 of the tape roll 5, and the tape 2 passes through the music box body 3 and is wound up. It is taken up by means 6. Since the tape 2 is wound into a roll,
It's compact. In this state, the tape 2 is wound around the winding means 6 from the head side of the music box music.
Therefore, it is necessary to rewind the tape 2 in preparation for the next music box performance. That is, the tape 2 is attached to the core member 1
Rewind to 6 and re-form the tape roll 5.

When re-forming the tape roll 5, first,
The rewind guide 28 is covered on the music box body 3 to hide the irregularities of the rollers 14 and the like. Next, the lead portion on the rear end side of the tape 2 is extended from above the music box body 3 to the core member 16 side and inserted into the slit of the core member 16. Since the lead portion on the rear end side is also reinforced by a thin plate like the lead portion 2b on the front end side, the lead portion can be easily inserted into the slit and a large frictional force is generated. On the other hand, the handle 7 is removed from the shaft 22 and connected to the tip of a rotary shaft 18 that rotates integrally with the core member 16.

Thereafter, the handle 7 is rotated to rotate the core member 1
Turn 6 to rewind Tape 2. In this case, after the tape 2 has been wound around the core member 16 several times, the frictional force of the tape 2 at the wound portion prevents the tape 2 from coming off the core member 16. Therefore, the tape 2 is the music box body 3
The tape roll 5 is formed again while being smoothly wound up while sliding on the upper side of the rewinding guide 28.

The tape roll 5 formed by rewinding the tape 2 is removed from the casing 4 by pushing the shaft 16b into the core member 16. The removed tape roll 5 is stored in the lower space 11 inside the casing 4. Further, the handle 7 is also removed from the rotary shaft 18 so that the lower space 11
Is stored inside. As a result, it is possible to prevent the supplies of the music box device 1, such as the tape roll 5 and the handle 7, from being lost.

The above-described embodiment is an example of the preferred embodiment of the present invention, but the present invention is not limited to this, and various modifications can be made without departing from the gist of the present invention. For example, in the above description, the present invention is based on a manual music box device, i.e., by rotating the handle 7 by hand.
Although the present invention is applied to the music box device 1 for rotating, it is also possible to apply it to an electric music box device. In this case, it is desirable to install an electric motor in the casing 4 and rotate the shaft 22 with the motor.

Further, in the above description, the lead portions reinforced by the thin plates 29 are provided at the front and rear ends of the tape 2, and the slits are formed in the core member 16 and the winding means 6. The side lead portion and the slit of the core member 16 corresponding thereto may be omitted.

A tape roll that is movably arranged and a winding unit that is housed in the casing and arranged on the other side of the music box body, and that winds the tape that extends from the tape roll and passes through the music box body into a roll shape. And a rotational force generating means for applying a tape driving force to the music box body, and a rotational force transmitting means for guiding a part of the tape driving force to the winding means to interlock the winding means with the music box body. Therefore, the tape can be handled as a roll without being handled as it is stretched, and the length of the tape can be increased. Can. Therefore, it becomes possible to change a music piece having a long playing time into a music box piece. Further, even if the length of the tape is increased, the tape is wound in a roll shape while playing the music box, so that the tape can be compactly packed, and the tape that is easily entangled and cut easily can be easily handled. Further, since the music box is played using the tape, the amount of wear of the diaphragm of the music box body is reduced, and the durability of the music box device is improved. Also, since the music box body can be made stronger than the tape, if the tape jams etc., the expensive music box body side will not be damaged, and only the damage on the tape side that is cheap and easy to replace can be stopped. become. Moreover, by changing the tape roll, the music box music can be easily changed.

In this case, it is desirable that the rotational force generating means manually generate the tape driving force.
In this case, it is not necessary to house a mainspring spring, an electric motor, or the like in the casing, the space in the casing can be effectively used, and the music box device can be downsized. Further, even when playing a music box piece having a long playing time, the rotational force, that is, the tape propulsion force is not interrupted during the performance.

Further, in this case, the rotational force transmitting means is
It is desirable that the belt is wound around the rotating body of the music box body and the rotating body of the winding means. In this case, the difference in rotation between the rotating bodies can be absorbed, so that damage to the tape or the music box body can be prevented.
