It has a function of, for example, a CD player for reproducing music information recorded in accordance with the standard (trument Digital Interface).

Here, the MIDI standard is a unified standard for transmitting performance information of electronic musical instruments such as synthesizers and electronic pianos as digital signals. Also, this MID
An electronic musical instrument equipped with hardware according to the I standard and having a function of transmitting and receiving a MIDI control signal, which is a musical instrument performance control signal of a format defined to carry music information, is called MID.
It is called I device. On the disk M, a subcode is recorded in addition to a main signal such as a music information signal.

The above subcode has empty channels R to W called user's bits, and MIDI format signals can be recorded in these user's bits R to W. In this case, in addition to supplying the audio / video signal reproduced by the CD player to the AV system to view the program recorded on the disc,
It becomes possible to supply performance program information to a MIDI device attached to the AV system. Therefore, since a MIDI device such as an electronic musical instrument can be operated in accordance with music or video, it is possible to construct an AV system with a sense of realism.

As shown in FIG. 7, at least one status byte for designating the type of data to be transmitted and the MIDI channel is combined with one or two data bytes 2 derived from the status. A message as control information is formed. Therefore, one message is composed of 1 to 2 bytes, and its transfer requires a transfer time of 320 to 960 [μsec].

Are fixed to the rotating shaft 103. A light-shielding plate 117 is fixed on the upper surface of the second wheel & pinion 113, and a bar 117 is attached to the light-shielding plate 117.
The bar 117a is formed so as to protrude, and the bar 117a shields the light receiving portion of the photosensor 118 mounted in the base 101. For example, the position of the doll 110 is turned to a position where the bar bell 112c can be hit. It has the function of detecting that

Then, as shown in FIG. 4, an output terminal t4 of the microcomputer 120 for controlling the entire operation is provided.
At t5, the pulse motor driver 126 for driving the pulse motor is connected. This pulse motor driver 1
26 is connected to a pulse motor 114 for moving the doll, and an output terminal t6 of the microcomputer 120 is connected to a drive circuit 108 of a solenoid 107 for driving a mulch 110 attached to the arm of the doll. The output terminal t3 of the microcomputer 120 has
The control output of the playback device 1 is connected.

A signal from the reproducing apparatus 1 is composed of channel data (channel number), scale data of barbell (note number), timing / length data (velocity), and these are input to the microcomputer 120.
Further, the microcomputer 120 has a function of calculating a movement signal of the doll to the target bell of the musical scale based on the signal data from the reproducing apparatus 1.

Next, the operation of the mechanism 12 will be described. When a start signal is input from the reproducing device 1, the pulse motor 114 starts to rotate, for example, clockwise. The rotation of the pulse motor 114 is transmitted to the second wheel & pinion 113 meshing with the gear 114a, and the second wheel & pinion 113 rotates clockwise, and the light shielding plate 117 fixed to the second wheel & pinion 113
When the bar 117a reaches the position of the photosensor 118, the pulse motor 114 is stopped by the detection signal from the photosensor 118 and the stop signal output from the microcomputer 120, and the pulse motor 114 is stopped.
Is set to the initial position.

The MIDI control signal output from the reproducing apparatus 1 is signal data for the performance of the doll 106 striking the sticks 112a to 112d, and indicates a channel signal indicating a channel number and a scale of the stick to be beaten. It includes a scale signal (note number) and a pitch signal (velocity) indicating the presence or absence of tapping and the pitch.

Then, in order to rotate the turntable 105 by the pulse motor 114 to the bar bell position of the scale indicated by the scale signal, the required number of pulses and the rotation direction are calculated. Next, from the output terminal t4 of the microcomputer 120,
Turntable 1 calculated by microcomputer 120
A pulse signal necessary for rotation to the target position 05 is output from the output terminal t5, and a direction signal indicating the rotation direction of the pulse motor 114 is output to the pulse motor driver 126.

Thus, the pulse motor driver 12
6, a drive signal is output and input to the pulse motor 114. The pulse motor 114 rotates a predetermined angle in the designated rotation direction, and the doll on the turntable 105 is rotated through the gear 114a and the second wheel 113. 106 is a barbell 112a-1
It stops rotating at the bar bell position to be beaten at 12d.

Next, the solenoid 107 is operated by the drive signal input to the drive circuit 108 from the output terminal t6 of the microcomputer 120, and the arm 106a of the doll 106 is rotated counterclockwise in FIG. Under the condition based on the data of the timing / duration signal, the barbell of the target scale is beaten by the collision table 110, and a barbell sound of a predetermined scale is emitted. Then, the same operation is repeated until the music ends.

It should be noted that a period of, for example, several hundred msec is required from when the MIDI control signal is received by the microcomputer 120 to when the sticks 112a to 112d are sounded by hitting with the hitch 110. Therefore, if a signal is simultaneously transmitted from the reproduction device 1 to the speaker 11 and the mechanism 12, the music output from the speaker 11 and the barbell sound emitted from the mechanism 12 are not synchronized. For this reason, in the present embodiment, as described later, the timing of the signal output from the reproduction device 1 to the speaker 11 and the timing of the signal output to the mechanism device 12 are adjusted.

Next, an example of the lighting device 13 will be described. The lighting device 13 shown in FIG. 5 includes a plurality of columnar transparent plastic members 51, a light emitting device 52 for emitting light from one end face of the plastic member 51, and a driver 10 for controlling the light emitting operation of the light emitting device 52. It is basically composed of

The plastic member 51 has a light diffusion / reflection layer formed on the outer peripheral surface. The light diffusion reflection layer is formed by applying, for example, a light diffusing white paint to the outer peripheral surface of the plastic member 51. From one end of the plastic member 51, the plastic member 51
When light is incident in the longitudinal direction of, the incident light is
Light is scattered from the outer peripheral surface to the outside by the diffusion action of the light diffusion / reflection layer, and light is reflected in the longitudinal direction by the reflection action of the light diffusion / reflection layer. The light once guided in the longitudinal direction by the light diffusion / reflection layer also divides into light scattered to the outside and light guided further in the longitudinal direction as it travels in the longitudinal direction.

That is, the light incident on the plastic member 51 is not scattered to the outside in the vicinity of one end but scattered to the outside while being guided in the longitudinal direction. As a result, the entire plastic member 51 appears to emit light. Therefore, if the light incident on the plastic member 51 is colored light, the plastic member 51 emits light in the hue of the colored light.

Although the plastic member 51 has a cylindrical shape, various shapes other than this shape, such as a helical shape and a repeatedly curved shape, can be used.

The light emitting device 52 receives light from one end face of the plastic member 51, and has a specific structure as shown in FIG. That is, the light-emitting devices 52 include light-emitting bodies 2R and 2R that emit light of three colors of red, green, and blue.
G and 2B are provided inside. Luminous bodies 2R, 2G,
For 2B, for example, a neon tube or a light emitting diode is used. Thus, RED, BLUE, GREEN 3
Since the light emitters 2R, 2G, and 2B of one color are provided, light of various colors is synthesized by appropriately selecting the light emitters 2R, 2G, and 2B and adjusting the luminance. Therefore, light of various colors is emitted from the plastic member 51.

The MIDI control signal output from the reproducing apparatus 1 has a configuration as shown in FIG. 7, and the note-on message of the status byte is caused to emit light, for example, from among the plurality of light emitting devices 52. A message for selecting the light emitting device 52 is used. The note-on message is, for example, a command corresponding to an operation of causing the light emitting device 52 to emit light, and is used in a pair with a note-off message corresponding to an operation of turning off the light emitting device 52. The note number of the data byte 1 is, for example, information for selecting which of the light emitters 2R, 2G, and 2B of the selected light emitting device 52 emits light.
The velocity of the data byte 2 is, for example, information for determining the luminance of light of a plurality of selected light emitters.

When the ratio of the light intensity of the luminous bodies 2R, 2G, 2B of the luminous device 52 is constant, the luminous bodies 2R, 2G, 2B,
With the combination of 2B, white, yellow, cyan, green, magenta, red, and blue colors can be created. In other words, the above-described colors can be created by writing information for appropriately selecting the luminous bodies 2R, 2G, and 2B to be illuminated in the note number of the data byte 1.

On the other hand, various colors can be created by mixing the three lights of red, green and blue emitted from the light emitters 2R, 2G and 2B and changing the ratio. That is, if information on the luminance of the three lights of red, green, and blue is written in the velocity of the data byte 2, the color can be further subtly changed.

A MIDI control signal for controlling the illumination device 13 is written, for example, as empty sub-code channels R to W on the disk M on which music information (audio signal) is written as main data.

When the disk M on which the MIDI control signal is written is mounted on the reproducing apparatus 1 and reproduced, the audio signal reproduced as main data is output to the amplifier and the music is played by the speaker 11. At this time, M is simultaneously transmitted to the driver 10 at the same time as the music information reproduced as the main data.
An IDI control signal is sent. The driver 10 has a decoding circuit for decoding the MIDI control signal in the above-described format, and has a MID for controlling the light emitting device 52.
Receiving the I control signal, the signal is decoded, and each light emitter 2R, 2R
G and 2B light emission operations are controlled.

Thus, the entire plastic member 1 emits light along with the music performance. For example, each plastic member 1 can emit light in various colors or emit light in a color tone corresponding to a musical theme.

However, the timing at which the MIDI control signal is output from the playback device 1 and the lighting device 13 receives the MIDI control signal and starts the light emission operation is not always completely synchronized with the output of the music from the speaker. . The timing at which the lighting device 13 emits light is not always synchronized with the operation of the mechanism device 12. For this reason, in the present embodiment,
The timing of signal output from the playback device 1 to the speaker 11, the mechanism device 12, and the illumination device 13 is adjusted.

Next, the reproducing apparatus 1 according to this embodiment will be described. As shown in FIG. 1, the display system according to the present embodiment includes an optical pickup 2, a microprocessor 3, a digital audio receiver 15,
A control characteristic data holding circuit 4, a reproducing apparatus 1 including memories 5 to 7, a D / A converter 16, an amplifier 8, a driver 9,
10, speaker 11, mechanism 12, illumination 13
have.

The optical pickup 2 includes music information and MID recorded on a disk M mounted on a turntable driven by a spindle motor (not shown).
It has a function of reading the I control signal. The signal read by the optical pickup 2 is output to the digital audio receiver 15, divided into digital audio data 15 a and subcode data 15 b, and output to the processor 3.

On the other hand, the control characteristic data holding circuit 4 is a circuit for holding the control characteristic data of the amplifier 8, the drivers 9, 10, the speaker 11, the mechanism 12, and the lighting device 13. Specifically, from the time when the audio signal and the MIDI control signal are input from the reproducing device 1 to the amplifier 8 and the drivers 9 and 10, the speaker 11, the mechanism device 12, and the lighting device 13 output sound or perform a predetermined operation. The response time until the start of the operation is stored. For example, speaker 11
The sound is output without delay by the input of the audio signal to the amplifier 8, the mechanism 12 has a time delay of 100 ms from the input of the MIDI control signal to the amplifier 9, and the lighting device 13 has the MIDI Assuming that there is a time delay of 50 ms from the input of the control signal to the amplifier 9 until the light emission operation is performed, the control characteristic data holding circuit 4 holds 0 ms, 100 ms, and 50 ms data. The input of data to the control characteristic data holding circuit 4 is performed by an external input / output device (not shown).

The audio signal of the disk information signal read by the optical pickup 2 is temporarily stored in the memory 5 after necessary signal processing is performed by the processor 3. On the other hand, among the disc information signals read by the optical pickup 2, the subcode data is converted into MIDI control signals by performing necessary signal processing by the processor 3 and then temporarily stored in the memories 6 and 7. You.

The processor 3 reads the data stored in the control characteristic data holding circuit 4 and synchronizes the sound from the speaker 11 with the operation of the mechanism 11 and the lighting device 13 based on the data. Of the signals stored in the memories 5, 6 and 7 are calculated. That is, in the above example, the MIDI control signal is first transmitted to the mechanism 12 having the longest time delay, the MIDI control signal is transmitted to the lighting device 13 after 50 ms has elapsed, and the audio signal is further transmitted to the amplifier 8 after 50 ms has elapsed. This is the timing for sending.

First, the processor 3 outputs a transmission signal 3b to the memory 6, whereby the memory 6
A MIDI control signal is sent to the mechanism 12. Next, a transmission signal 3c is output to the memory 7, whereby the MID is transmitted from the memory 7 to the lighting device 13.
An I control signal is sent. Finally, the transmission signal 3a is output to the memory 5, whereby the memory 5
An audio signal is transmitted to the amplifier 8 through the / A converter 16. As a result, predetermined music is output from the speaker 11, and in synchronization with the music, the mechanism device 12 and the lighting device 13 operate.

As described above, according to the display system of the present embodiment, for example, in a show window or an event venue, the mechanism device 12 and the lighting device 13 simultaneously and unifiedly operate according to music. The atmosphere and impression of the place can be greatly improved. Further, according to the display system of the present embodiment, since the music and the operations of the mechanism device 12 and the lighting device 13 are uniformly synchronized, a feedback signal indicating the operation state of the mechanism device 12 and the lighting device 13 is reproduced. It is not necessary to feed back to 1 and the system can be prevented from becoming complicated. In the present embodiment, only the mechanism device 12 and the illumination device 13 are shown as controlled devices. However, the present invention is not limited to these.
The number of controlled devices that can be connected to the device can be used, and a controlled device such as a video device or a robot can be used other than the mechanism device 12 and the lighting device 13.

As described above, according to the present invention,
Since the music and the plurality of controlled devices are synchronized in a unified manner, it is possible to greatly improve the atmosphere, the impression, and the sense of reality in, for example, a show window or an event venue.
