2. Description of the Related Art In general, the sounding means used for informing a clock or the like is not limited to one that obtains an inorganic electronic sound by using a sounding circuit, a speaker, etc., but a soft and old-fashioned sound is obtained by using a mechanical music box device. It is known to obtain a music box sound.

Such a music box device often plays a single piece of music prepared in advance, and a long plate-shaped music box sounding body having a plurality of sounding portions corresponding to the number of pitches and the music box. It is placed facing the sounding body,
It is composed of a drum body, which is provided at a proper position on the outer periphery thereof with a projection for plucking the sounding portion of the sounding body at a predetermined performance timing, and a drive unit for rotationally driving the drum body at a constant speed.

That is, this sounding body is formed by forming a metal plate having a substantially long plate shape into a comb tooth shape which is a predetermined number of sounding portions corresponding to the number of scales, and these comb tooth portions (music box valves) have a predetermined shape. It is formed to have a length and a thickness, and when the tip of the music box valve is flipped, a music box sound of a scale to be shared is generated. Further, the drum body is formed in a cylindrical shape at least longer than the sounding body, and is rotatably arranged so as to face the sounding portion of the sounding body, and the outer periphery corresponding to the sounding portion of the sounding body is intermittently adjusted according to the music. Projections are formed. Then, the drive unit rotationally drives the drum body in a certain direction at a predetermined speed, and each projection of the drum body snaps each sounding portion of the sounding body at a predetermined timing, thereby playing the music box. There is.

Further, instead of such a drum body, a disc-shaped music box disc having an engagement drive portion for making a sounding operation of each sounding portion of the sounding body is used, and this music box disc is replaceable. Therefore, a music box device that allows the user to play an arbitrary music box has also been proposed.

The music box disc of such a music box device is formed in the shape of a metal disk, and one surface of the music box disc is divided into a plurality of tracks according to the music box valve of the sounding body, and the musical scales shared by the tracks are played. Engagement drive portions are formed at locations in the circumferential direction according to the timing, and these engagement drive portions are formed by projections or holes having a predetermined diameter protruding from one surface of the music box disc.

Then, by using such an engagement drive section,
A music box is played by plucking a predetermined part of the sounding body.

A music box using this music box disc is one in which a disc-shaped music box disc having a large number of engagement drive parts is mounted for playing a music box. The music box disc is rotationally driven by a drive mechanism of the music box main body. On the other hand, a star wheel that flips the music box valve of the sounding body is rotatably attached to the star wheel shaft in the main body of the music box. Then, when the music box disc is rotated by the drive mechanism, the engagement drive unit of the music box disc hooks the claw of the star wheel corresponding to the engagement drive unit to rotate the star wheel, and follows the rotating star wheel. It is a music box that plays a melody by playing a music box valve with another claw to generate a music box sound.

In this disc music box, a music box disc of a portion facing the star wheel is held by being pressed from one side by a music box disc pressing arm having a pressing roller to hold the music box. A disc can be used.
Therefore, a large number of music box discs having different music patterns can be manufactured at low cost, and since the music box disc itself has a thin disc shape, it can be easily stored and stored, and can be efficiently transported.

Further, since the music box disc itself is easy to handle, it can be easily attached to and detached from the music box, and the music box disc can be replaced in a short time. Therefore, by preparing a plurality of music box discs of different songs in advance, by selecting any song from these music box discs and exchanging the music box discs,
The music to be played by the music box can be changed quickly and easily.

As described above, the disc music box can be easily mounted by selecting an arbitrary music box disc from a plurality of music box discs, as compared with a fixed drum type music box dedicated to one piece of music. In addition, it has an advantage that the music piece can be changed flexibly and easily.

[0012]

In such a music box device, in order to cooperate with other equipment, a time chart is prepared in advance, and the music box performance and the operation of the equipment are controlled according to the time chart. It has been mainly done.

That is, for example, in a Karakuri clock that performs a Karakuri operation at a predetermined time, a music box performance is started based on the time chart prepared in advance, and a Karakuri doll or the like is played at the timing recorded in this time chart. Controlled the operation of linked devices. Therefore, with a simple configuration, even if the music changes, the mechanical operation by the device is the same, which is inconvenient.

Further, there is a problem that it is difficult to perform flexible control according to a music piece, and a compact instrument such as a domestic clockwork has a circuit configuration which is too complicated to be applied.

Further, when the sound hole is also used for device control, that is, when the control signal of each device is directly obtained from the sounding pattern, the scale of the tune is judged and then the control signal is sent. Since it is generated, the circuit configuration and the like also become complicated.

In any case, for the music box performance, since the equipment is indirectly controlled, it is difficult to finely control the equipment, and the circuit configuration becomes complicated.

Therefore, an object of the present invention is to provide an information disk capable of acquiring a sounding operation of a real sound and a control signal linked or synchronized with the sounding operation and an output device thereof.

The basic structure of the information disc and its output device described below is the same as that of the music box disc and music box device described later. Therefore, the basic structure will be described first, and then the information disc and the output device will be described. A part peculiar to the output device will be described.

That is, the output device 20 uses the information disc 1 that can be easily and quickly exchanged to perform a music box performance of a real sound, and directly outputs control information for operating other external equipment in association with the music box performance. The information disc 1 will be described below for convenience of explanation.

Gear wheels 23c meshed with each other are provided, and a drive projection 23d is provided on the turn plate 23 at a position corresponding to the drive hole 4 of the information disk 1 so as to project upward.

In the figure, reference numeral 29 is a supporting member formed of synthetic resin and arranged on the outer peripheral side of the information disc 1, and the turn plate 23 supports the lower surface on the inner peripheral side of the information disc 1. In addition, the support member 29 supports the lower surface on the outer peripheral side of the information disc 1 so that the rotation of the information disc 1 can be smoothly and stabilized. Further, the supporting member 29 may be a rotating member instead of such a fixing member.

Further, the turn plate 23 is the driving mechanism 2
4, the turn plate 23 is rotationally driven in a constant rotational direction at a constant speed when the music box is played.

This drive mechanism 24, as shown in FIG.
When the information disc 1 is mounted on the turn plate 23, the motor M arranged so as to be located outside the information disc 1 and the rotation output of the motor M are used as a turn plate on the inner circumference side of the information disc 1. 23, the first input gear 32, the transmission shaft 33, the first output gear 34,
It is composed of the second gear 35.

As the motor M, a DC motor is used,
On the outside of the information disk 1, its motor shaft is attached to the base 2
It is fixed to the base 21 parallel to the plane 1 and orthogonal to the longitudinal direction of the holding arm 25. Therefore, the motor M can be stably held on the flat surface of the base 21, and the thickness of the entire output device 20 can be set to a height of about the minimum motor diameter, so that the output device 20 can be made thin. You can

The connection terminal of the motor M is connected to a motor drive circuit (not shown), and is operated by a drive current supplied from the motor drive circuit. Further, as will be described later, the motor M is configured so as not to operate when the holding arm 25 is unlocked by the safety switch mechanism 37.

Further, a worm gear 31 is fixed to the output shaft of the motor M, and a first input gear 32 is meshed with the worm gear 31. The first input gear 32 is
The transmission shaft 33 is fixed to one end of a transmission shaft 33 that is orthogonal to the longitudinal direction of the motor output shaft and is parallel to the star wheel shaft 26A. The other end of the transmission shaft 33 has a first output gear 34.
Is stuck. The first output gear 34 meshes with the input gear portion 35a of the second gear 35, and the output gear portion 35b integrally formed with the second gear 35 is integrally formed at the base end of the turn plate 23. It meshes with the gear portion 23c.

The second gear 35 is integrally provided with an input gear portion 35a and an output gear portion 35b having rotating surfaces orthogonal to each other, and the input gear portion 35a has an outer peripheral edge on a substantially circular plate in the axial direction. And a tooth portion is engraved on the projected end surface, and meshes with the first output gear 34.

Further, the output gear portion 35 of the second gear 35
The gear b is coaxial with the input gear portion 35a and has an outer tooth shape with a predetermined outer diameter, and is meshed with a gear portion 23c integrally formed at the base end of the turn plate 23. Therefore, the rotation of the first output gear 34 in the direction orthogonal to the rotation axis,
It transmits to the turn plate 23 provided on the base 21 while decelerating.

Further, the gears 3 meshing with each other.
A predetermined reduction ratio is set between 1, 32, 34, 35b and 23c.

Therefore, the rotational driving force of the motor M is transmitted to the turn plate 23 while being decelerated to a predetermined speed by the drive mechanism 24, and the information disk 1 mounted on the turn plate 23 is rotated at a predetermined rotational speed. Let

Further, as shown again in FIGS. 1 and 2, the holding arm 25 is formed in a substantially long plate shape longer than at least the radial length of the information disc 1, and its base end is pivotally supported by the base 21. The information disk 1 mounted so that the front end is erected on the central shaft 22 provided upright on the base 21 is mounted on the star wheel 2 on the base 21 side.
The roller 25a that presses while rotating to 6 is provided.

That is, the holding arm 2 at the tip of the central shaft 22
A notch portion 22a is provided at a position where 5 is engaged, and a lock arm 25b having a predetermined shape is provided at a corresponding portion of the holding arm 25 according to the notch portion 22a. Is spring-biased so that its tip engages with the notch 22a.

Therefore, unless the user performs an operation for releasing the engagement of the lock arm 25b, the information disc 1 is securely attached to and held by the output device 20, and the output device 20 is held.
Stable holding of the information disc 1 regardless of its own posture,
I can play the music box. On the other hand, by unlocking the holding arm 25 and swinging the holding arm 25 to stand up, the information disc 1 can be quickly and easily replaced.

Further, in this example, a safety switch mechanism 37 for confirming whether or not the holding arm 25 is locked is provided.

That is, as shown in FIG. 2, the safety switch mechanism 37 has a protrusion 38 provided outside the information disc 1 of the holding arm 25 and facing the information disc 1, and a protrusion 38. Correspondingly, it is composed of a micro switch 39 having a raising / lowering switch lever 39a provided at a predetermined position of the base 21, and this micro switch 39 electrically transmits a start signal for starting the music box performance. It is connected in series to the signal line.

The micro switch 39 is fixed to the base 21 in correspondence with the protrusion 38, and a general tilting switch lever 39a is provided on the upper portion thereof.
The base has an electrical switch connection terminal.

The switch lever 39a is biased by a spring or the like so as to stand upright, and when it stands up,
As a switch, the switch is electrically turned off and cut off, and is turned on when the switch lever 39a is tilted.

Therefore, when the holding arm 25 is opened, the projection 38 provided on the holding arm 25 separates from the micro switch 39, the switch lever 39a of the micro switch 39 stands up, and the switch 39 is cut off. The operation of the output device 20 is suppressed. On the other hand, when the holding arm 25 is in the locked state, the protrusion 38 of the holding arm 25 approaches the micro switch 39 and the switch lever 39a is tilted to bring the switch 39 into the connected state so that the output device 20 can be operated. Become.

In addition to this, the set state of the information disc 1 can be determined at the same time. That is, similarly, a micro switch 39 having a switch lever 39a protruding toward the information disc 1 by a predetermined amount is provided at a position of the holding arm 25 facing the information disc 1, and the micro switch 39 is connected to a control circuit. Good.
Therefore, in this case, similarly, when the holding arm 25 is opened, the switch lever 39a of the micro switch 39 is in the upright state and the operation of the music box is suppressed, but when the information disc 1 is not attached, Even if the holding arm 25 is locked, the switch lever 39a does not come into contact with the information disc 1, so that the switch lever 39a is in the upright state and the operation of the output device 20 is suppressed.

Therefore, such a safety switch mechanism 37
Since it is possible to prevent malfunctions when the music box disc is not attached, the music box can be played during the music box performance for some reason or even if the holding arm 25 is unlocked by the user. It is possible to immediately stop the playing operation, prevent various damages, human accidents, etc., and improve safety.

Particularly, for example, the information disc 1 of this example is
Although it is relatively small, if a larger disk is used and the safety switch mechanism 37 of this example is provided, the drive motor can be stopped immediately and sufficient safety is ensured. it can. In other words, since a large disk is driven to rotate, a relatively powerful motor is used as the drive motor, and it cannot be handled manually, so the motor does not malfunction unless it is operating normally. However, according to the safety switch mechanism 37, it is possible to sufficiently cope with the situation.

Further, the sounding mechanism 30 is accompanied with the turn plate 23 which is rotationally driven by the drive mechanism 24, and the star wheel 26 which is engaged with each of the performance engaging portions 3a of the information disk 1 which is rotationally driven, This star wheel 26
And a music box sounding body 27 having a music box valve portion 27a driven by.

That is, in FIG. 1 and FIG. 2, the music box sounding body 27 for sounding the music box is formed in a long plate shape using a metal material, and is arranged on the base 21 so as to be parallel to the information disk 1. ing. The end of the music box sounding body 27 on one end side is provided with a music box valve portion 27a formed in a comb tooth shape so that the end portion on the side of the music box valve portion 27a is aligned in the radial direction of the information disc 1 corresponding to the holding arm 25. The base end on the other end side is fixed to a pedestal portion provided on the base 21. Further, a predetermined number of these music box valve portions 27a, 27a are provided according to the number of scales to be pronounced, and each is formed to have a predetermined thickness and length according to the scale, and these music box valve portions 27 are formed.
It is provided so that when the tips of a and 27a are played, a music box sound of a predetermined scale / pitch is generated.

A plurality of star wheels 26 corresponding to the number of scale tracks of the information disc 1 are rotatably supported by a star wheel shaft 26A at a position on the lower surface side of the information disc 1 corresponding to the holding arm 25. ing.

On the outer circumference of these star wheels 26,
Eight claw portions 26a are arranged at equal intervals so that they can be engaged with the performance engaging portions 3a of the information disc 1 at any rotational position.
The claws 26a are provided with a front surface in the rotational direction of the claw portion 26a formed into an acute slope surface, while the rear side thereof is formed into a surface orthogonal to the rotational direction. The engagement with the mating portion 3a (projection 6) is ensured.

Therefore, the performance engaging portion 3 of the information disc 1
As compared with the type in which holes are provided, the protrusion type is a, so that the claw portions 26a of all the star wheels 26,
It is not necessary to align the 26a in a row or to urge the star wheel 26 to rotate in the rotational direction so that the claws 26a are surely engaged with the holes, thereby simplifying the mechanism.

Further, at a position of the base 21 facing each star wheel 26, a separating member having a same number of gaps as the star wheel 26 and a predetermined width is provided by using a synthetic resin capable of reducing friction. Each star wheel 26 is held at a predetermined interval along the longitudinal direction of the star wheel shaft 26A. Therefore, each star wheel 26
Are rotatably arranged so that the music box valve portion 27a of the corresponding music box sounding body 27 can always maintain a position facing each other.

After the information disk 1 arbitrarily selected by the user is mounted on the base 21, a control circuit (not shown) outputs a start signal at the hour, or a monitor (not shown) is also provided. When the user turns on the switch, the information disk 1 is rotationally driven by the drive mechanism 24, and the music box valve portion 27a corresponding to the musical scale of the music piece is clawed by the claw portion 26a of the star wheel 26 at a predetermined timing. Music box performance is performed.

That is, the projections of the performance engaging portions 3a of the information disc 1 hook the claw portions 26a of the star wheel 26 corresponding to the performance engaging portions 3a to forcibly rotate the star wheel 26. Then, the other claw portion 26a of the rotating star wheel 26 subsequent thereto finally flips the music box valve portion 27a to generate a music box sound.

As shown in FIG. 7, the information disc 1 is rotationally driven (FIG. 7 (1)), and the performance engaging portion 3a is engaged with, for example, the claw portion 26a of the claw portions 26a of the star wheel 26. 7 (2), the claw portion 26a is forcibly moved by the projection 6 of the performance engaging portion 3a, and the star wheel 26 is rotated. At this time, the star wheel 26
The claw portion 26a subsequent to the claw portion 26a of the
7a (FIG. 7 (3)), and further rotationally moved to claw the music box valve portion 27a (FIG. 7 (4)).
A music box sound of a specific scale of the music box valve section 27a is generated.

Further, an automatic stop mechanism 41 is provided which automatically stops when the information disc 1 makes one revolution, which is applicable to a mechanical clock or the like (see FIG. 1). That is, the operation of the motor M is automatically stopped when the music box performance of one piece of music corresponding to one rotation of the information disc 1 is completed.

The auto-stop mechanism 41 comprises a notch 42 for detection provided on the turn plate 23 and a micro switch 43 for detection provided at a predetermined position on the base 21.

In order to enable the automatic stop mechanism 41, positioning holes 44 and 45 for positioning and incorporating the rotational position of the turn plate 23 at the one-rotation detection position by the microswitch 43 are provided in the base 21. And the turn plate 23.

That is, since the drive hole 4 of the information disc 1 is engaged with the drive projection 23b provided on the turn plate 23 to mount the information disc 1 on the turn plate 23, the turn plate 23 is always mounted on the turn plate 23. On the other hand, the information disc 1 is mounted at the same rotation angle position. Therefore, the performance start position of the information disc 1 mounted on the turn plate 23 with respect to the base 21 is always constant, and even if the relational position between the two is slightly deviated, the music box performance cannot be started and ended normally.

That is, when the turn plate 23 is rotationally driven and the notch 42 of the turn plate 23 reaches the detection position of the micro switch 43, the rotation of the information disc 1 is restricted by the drive protrusion 23b of the turn plate 23. It is necessary to always set the rotation position to the performance end position (hereinafter referred to as the rotation reference position).

That is, as shown in FIG. 1 and FIG. 2 again, the auto stop mechanism 41 includes the turn plate 2
3, the outer circumference of the support portion 23b of No. 3 is composed of a notch portion 42 provided in a predetermined length in the circumferential direction, and a micro switch 43 provided in a predetermined position of the base 21 which is a disk music box fixed side member. By incorporating the turn plate 23 while engaging the pins with the positioning holes 44 and 45 provided in the base 21 and the turn plate 23, the turn plate 23 can be provided at an appropriate rotation reference position.

The position where the micro switch 43 is installed and the position where the cutout portion 42 is provided are defined by the turn plate 2
With reference to the position of the drive protrusion 23d provided on the reference numeral 3, the rotational position of the information disk 1 by the drive protrusion 23d is set to the start or play end position when they coincide with each other vertically.

Further, the distance between the micro switch 43 and the lower surface of the supporting portion 23b of the turn plate 23 is shorter than the entire length of the switch lever, that is, the switch lever moves to the supporting portion 23b at the rotational position during the playing of the music box.
The distance is set such that it abuts the lower surface of the and is tilted. Further, the micro switch 43 performs a switch operation opposite to the normal operation, and outputs an off signal when the switch lever is tilted, while outputting a switch on signal when the switch lever stands up. It is configured.

However, the present invention is not limited to this, and the output terminal of the normal setting microswitch 43 may be connected to the outside through an inversion circuit that inverts the output signal.

Further, the supporting portion 23b of the turn plate 23
The notch portion 42 provided at is formed with a predetermined length in the circumferential direction so as to ensure detection at the position on the outer periphery of the support portion 23b and at the position satisfying the above-mentioned conditions.

Therefore, when the turn plate 23, that is, the information disk 1 is driven to rotate during the music box performance and reaches the reference rotational position at which the performance is completed after one rotation,
Notch portion 4 provided in the support portion 23b of the turn plate 23
Since 2 is located immediately above the micro switch 43, the switch lever of the micro switch 43 stands up, the micro switch 43 outputs an ON state detection signal, and the control circuit rotates the information disk 1 based on this detection signal. Driving can be stopped, and auto stop mechanism 4
1 can be realized.

Further, since the information disc 1 itself is detected by the turn plate 23 without forming a molding portion such as a claw portion or a hole portion for detecting one rotation position, the production of the information disc 1 itself to be produced in large numbers. In addition, it is possible to prevent the rotation stop position from being impossible to detect when the molding portion is formed on the disc side when the molding portion is damaged.

The positioning holes 44 and 45 are not limited to the through holes, but may be any suitable one such as a blind hole or a cutout groove. In addition, in the present specification, the engaging portions generally used for the above-described positioning such as the through hole, the blind hole, and the notch groove are referred to as a positioning hole.

Further, once assembled, the turn plate 23 meshes with the output gear of the drive mechanism 24 described above, so that the mutual relationship, that is, the rotational position can be surely prevented from shifting. .

Next, the information engaging portion 5a provided on the information truck 5 and the contact mechanism 50 which is an output control device for acquiring control information from the information engaging portion 5a will be described.

As shown in FIG. 3 again, the information disc 1 of this example is for playing corresponding to each scale provided with a predetermined number of playing engaging portions 3a from the inner circumference to the outer circumference as described above. The tracks 3 and the information tracks 5 provided with a predetermined number of information engaging portions 5a are alternately provided, and one or a plurality of the information tracks 5 are combined to provide control information for other devices. I'm trying to get it.

Therefore, by alternately arranging the performance tracks and the information tracks on the information disc, the engaging portions provided on these tracks are used to engage the sound generation / contact mechanism of each sound generation / contact mechanism. It is possible to configure the mating portion and the contact movable portion, etc. with an appropriate distance from each other,
Therefore, the design can be done without difficulty, and low cost and sufficient reliability can be secured. In particular, for example, a general microswitch can be used as the engagement detection mechanism of the contact mechanism 50 that detects the engagement portion, and it is possible to reduce costs and improve reliability.

The information engaging portion 5a provided on the information track 5 basically differs depending on the device controlled by the information track 5, but basically corresponds to the sounding timing of a certain scale. It is provided.

For example, the certain information engaging portion 5a is provided by shifting the 1/2 rotation cycle phase of the information disk 1 with reference to the sounding timing of a certain scale, and as described later, the rotation of the disk. The drive is good.

Further, the information engaging portion 5a is disposed slightly offset in the forward direction of rotation in consideration of the time lag until the device actually outputs sound based on the acquired control signal. There is. Therefore, since the sounding operation by the other device synchronized with the sounding of the music box with sufficient accuracy is enabled, it is possible to perform more precise and strict control.

Further, since the outer peripheral side of the information disc 1 has a long distance in the portion which moves in the rotational circumferential direction, it is used for control of equipment requiring higher accuracy or for control tracks for recording higher density control information. It is assigned.

Incidentally, the control information constituted by the information engaging portion 5a provided on the control track as described above can be arbitrarily set, for example, in synchronization with all the music box sounds or only in the time signature. it can.

Further, the device can be controlled regardless of the sounding timing of the music box performance. For example, even when the performance is stopped, the device can be made to perform an arbitrary operation such as a preparatory operation, and flexible control according to the device can be performed.

Further, the single information track 5 may be configured to be switched and used according to the rotation cycle thereof. That is, for example, when the music box performance is composed of three parts of a prelude theme, a main theme, and an ending theme, a control signal obtained from the same information track 5 for each theme, It may be used by switching to a different device.

Further, the contact mechanism 50 which detects the information engaging portion 5a and outputs the control signal is, for example, as shown in FIG. 8, a general mechanical detecting mechanism including a micro switch or the like. And has electrical contacts operated by the information engaging portion 5a, and the output terminals of these contacts are directly connected to a drive circuit for a linking device (not shown), Alternatively, it is connected to an integrated control circuit or the like that integrally controls each device.

That is, like the music box valve 27a of the music box sounding body 27, through the star wheel 26,
A switch group is provided so that the switch can be operated by the engagement protrusion 6 of the information disk 1. In this case, the star wheel 26 is turned on and off by the rotation of the star wheel 26, and it is conceivable to separately form the engaging projection 6 whose height is adjusted only for this switch.

Therefore, the contact point mechanism 50 can be assembled with the same accuracy as the sounding mechanism 30, the workability and the assemblability are improved, and the switch operation is performed with the same accuracy as the sounding operation timing of the music box sounding body 27. The switch signal can be used as a reference signal for various advanced controls.

The contact mechanism 50 is used in the output device 20.
It is provided on the base table 21 at a position shifted by a 1/2 phase cycle in the phase cycle of one rotation of the information disk, and the detection position of each contact is the star wheel 2 of the sounding mechanism 30.
The engagement position of 6 and the engagement position of 6 are substantially aligned with each other.

That is, the star wheel 26 of the sounding mechanism 30 engages with the performance engaging portion of the information disc 1, and the star wheel 26 of the contact mechanism 50 engages with the information engaging portion of the information disc 1. Location means Information Disc 1
They are installed so as to be lined up on a substantially symmetric straight line with respect to the rotation center axis of the.

Therefore, since the performance and control information is always obtained from the position aligned on the straight line with respect to the information disc 1 in this way, the pressed state of the information disc 1 becomes good, and it is smooth and good. The rotation drive of the disk can be maintained.

Further, it is possible to secure a sufficient installation space for the contact mechanism without reducing the conventional installation space for the sounding mechanism, and it is possible to arrange both of them without difficulty.

The arrangement position of the sound generating mechanism 30 and the contact mechanism 50 is not limited to this, and when these are appropriately combined to constitute the three sound generating mechanisms 30 or the contact mechanism 50,
It may be provided at intervals of 120 ° in the circumferential direction.

Therefore, the performance engaging portion 3a and the information engaging portion 5a dedicated to the linking device are provided side by side on the same information disc 1 so that the device linked to the performance is directly controlled. Therefore, the fineness of control and the flexibility can be improved.

Next, the operation control of the output device 20 using such an information disc 1 will be described.

First, when the user turns on the monitor switch or when a predetermined time comes, the predetermined music box performance and the operation of the device associated with this performance are started.

That is, the motor control circuit of the output device 20 drives the motor M in a predetermined manner, and the motor drive drives the information disk 1 to rotate in the forward direction from the performance start position. As the information disc 1 rotates, the performance engaging portion 3a provided at a predetermined position of the performance track 3 of the information disc 1 hooks the claw 26a of the corresponding star wheel 26, and the star wheel 26 Two
6 forcibly rotates this rotating star wheel 2
The other claw 26a subsequent to 6 plays the music box valve 27a of the music box sounding body 27 to produce a predetermined music box sound.

At the same time, an information engaging portion 5a provided at a predetermined position on the information track 5 of the information disc 1.
However, when reaching the detection position by the contact mechanism 50, a control signal is output from the contact mechanism 50, and the device at the subsequent stage operates via the drive circuit, the control circuit, and the like. That is, the linked device in the subsequent stage is appropriately driven and controlled in association with the music box performance, and the operation synchronized with the sounding timing in a predetermined manner is executed.

Finally, after the information disc 1 has been driven for one predetermined rotation, the music box performance ends. That is, the automatic stop mechanism 41 stops the information disc 1 at the rotational position in the initial state where the music box performance starts.

The contact mechanism 50 used in the present invention is not particularly limited as long as it does not hinder the smooth rotation of the disk and ensures sufficient durability, and various general and inexpensive switches are used. The configuration may be different.

Further, in the above-described specific example, the example in which the device is controlled based on the music box performance has been described, but conversely, the configuration is such that the music box performance is performed based on the operation of the device. Of course, both can be combined in parallel so that a more comprehensive control effect can be obtained.

As described above, according to the information disc of the present example, the performance track provided with the performance engagement portion used for generating the actual sound of the sounding body and the information engagement of the device linked to the performance. The information track provided with a section is provided on the same information disc, and since the linked device can be directly controlled along with the actual sound performance, it is possible to directly relate to the actual sound performance,
Moreover, the devices can be controlled in parallel, and the circuit configuration can be simplified.

Further, by alternately arranging the performance tracks and the information tracks on the information disc, the engaging portions provided on these tracks are used to engage the engaging portions of the sound producing / contact mechanism for producing sound and signals. The contact movable parts and the like can be appropriately spaced from each other, so that the design thereof can be made reasonably, and low cost and sufficient reliability can be secured.

Further, since the sound generating mechanism and the contact mechanism are arranged at symmetrical positions with respect to the rotation axis of the information disc, the engagement points for obtaining the performance and control information are located on a substantially straight line with respect to the information disc. I try to match the range. Therefore, the pressed state of the information disc becomes good, the rotational drive of the disc can be smoothly and favorably maintained, and a sufficient installation space for the sound generation / contact mechanism can be secured. can do.

Further, since the control information of different equipments can be recorded for each disc and the discs can be easily exchanged, it is possible to flexibly change not only the music but also the operation of the equipment according to the situation. . For example, by preparing a disc in which different control information is recorded for the same tune in advance, it is quick and easy to make the linking device perform different operations even for the same tune only by exchanging the disc. You can

Furthermore, even if the rotation speed of the disc during the performance, that is, the time signature of the music is changed, the operation of the device can be automatically followed.

Next, the information disc and its apparatus of the present invention will be explained based on the second specific example shown in FIG. The output device 20 using the information disk 1 of the present specific example has a contact mechanism 50 in which a music box sounding body different from the sounding mechanism 30 is incorporated.

That is, as shown in FIG. 9, the contact mechanism 5
A music box sounding body 27 'having a music box valve 27a is arranged on the inner circumference side of 0, and the information track on the inner circumference side of the information disc 1 corresponding to this is used as the performance track 3 A joint is provided.

This music box sounding body 27 'may be made to have a material or shape different from that of the music box sounding body 27 of the sounding mechanism 30 so as to use an obviously different tone color. It can be used as a prelude to improve the expressiveness of music box performance.

Further, since the outer peripheral side of the information disc 1 having a long moving distance in the circumferential direction is assigned to the information track 5, it is possible to record and obtain the control information with higher density and higher accuracy. ing.

As described above, according to this example, not only the same effects as those of the above-described first specific example are obtained, but also a separate sounding body is added to the contact mechanism, so that the number of scales is increased. , Different tones can be used, and the expressiveness of the music box performance can be further enhanced.

The present invention may use an appropriate output control device such as an optical reading mechanism in addition to the contact mechanism 50 using the general mechanical detection mechanism described above.
