speakers of either A, B or CRT device 2)
At the same time, the driver selects the power source or the drive device for the output light of the activation signal (eye/daily motors, hand/foot motors of characters A and B) and activates them.

The deciphering elements of the control image are the difference in black and white, the difference in color, the difference in black and white ratio,
Various methods are used, such as simple shape pattern recognition and black and white digital signals.

Characters A and B each have their limbs, eyes, and mouth moved by two motors serving as two drive devices, as shown in FIGS. 2 to 10.

First, the movements of the limbs will be explained with reference to FIGS. 2 and 3.

8 is a motor as a first driving device, and a pinion 9
The hand 11 is made to swing through a gear train 10, and one leg 13 is also made to swing by a gear train 12 at the same time. 14 is fixed to the stand 15 with the other leg, and holds the character A upright.

The hand 11 and foot 13 are normally vertical, but when the motor 8 is activated, they swing as shown at 11' and 13'.

1G is a dedicated speaker for character-A and is built into character-A. A dedicated speaker may be provided in a location separate from Character-A. The speaker for character-B may be dedicated or common to character-A, and the speaker 7 of the CRT device 2 may be used for character-A.

It may be used in common for B purposes. 17 is a sound sensor that detects audio. 18 is the drive circuit, and the leg on the fixed side! A conductive wire (not shown) provided along the base 15

The movement of the mouth is controlled by installing cams on the top and bottom of the back side of the slit 25.
If a striker, which is a protrusion, is provided on the surface of the moving plate 20, and the striker hits the cam at the end of the left and right movement stroke, the slit 25 is opened as shown in FIG.
The mouth opens and closes to create the illusion of speaking.

The movement during activation may be such that other parts of the eyes, mouth, hands, and feet move, or the entire body may move.

Such a character 1 and a CRT device 2 which is a video device
The circuit and its functions for producing interaction with the image on the screen will be explained with reference to FIGS. 11 and 12.

In FIG. 12, a video tape 33 to be played back by a VTR 5 has a video track including a CRT! The image data of CRT device 2 is recorded, and the audio trunk is a stereo track with an R track.
On the L track, the audio for character B and the stereo L side audio of the CRT device 2 are recorded.

The sounds for the CRT device L2 include the sounds of the screen character 34, BGM, narration, and the like.

Details of the control circuit 6 are as shown in FIG.

Recording is performed on the video track of the video tape 33 so that an image for a predetermined image signal is generated in a predetermined range at the corner of the screen according to a predetermined program.

The detection output from the screen detection sensor 1 is decoded by a screen signal decoder and input to the output control section. The output control section outputs a control signal to the switching means for switching the R audio signal and the L audio signal to the speakers of the R and L channels of the character A and B or the CRT device 2, and the motor. A control signal is output to the drive unit to switch the power supply or operation signal to each motor, making it possible to perform complex interactions and operations according to the program.

The audio track of the videotape 33 includes a
Characters A, B, screen characters 34, narration, BGM, dialogues, songs, explanations, music, etc. are recorded in program order according to the rules, and when this videotape 33 is played back by the VTR 5, the characters can be recorded.
A and B can perform an effect as if they were having a dialogue with each other, with the screen character 34 on screen 3, or with the narration on screen 3.

In addition, the recording medium and reproducing device are commercially available video tapes and VTRs that are easy to handle, have a 1'1 structure, are easy to maintain, and are extremely easy to program.

Furthermore, since the audio from the CRT device 2 is stereo, a great sense of realism can be obtained.

The above explanation uses a videotape with a double audio track of R and L and one character. The device allows more than one character to participate in an interaction with the screen. If there are multiple characters,
The speakers may be provided for exclusive use, respectively, or may be used in common.

Regarding the deployment and sound production of the speaker for the operating body that emits the sound for the character (single or plural) and the attached speaker (built-in or separate) attached to the video device such as a CRT device (one or two in the case of stereo) , for example the following (i)
Various combinations such as (ii) and (iii) are used.

(i) Each of the operating body(s) and the video device is equipped with a separate dedicated speaker to emit their respective sounds.

(ii) If there are multiple actuators, some or all of them are provided with a common actuator speaker (or built into or separately installed in the actuator), and the sounds of each of the common actuators are transmitted from the common actuator speaker. The audio for the video device is generated from the attached speaker.

(iii) The speaker is the only one attached to the video machine, which also serves as the speaker for the operating body, and both the sound for the operating body and the sound for the video machine are generated from this attached speaker. (In this specification, the attached speaker that generates sound for the operating body in this manner is also included in the term "speaker for the operating body."

) In addition, various combinations are used, such as omitting the attached speaker and using only the operating body speaker.

If the device is small, or if the actuators are close to each other or the video device, there is no problem in using a common speaker as described above.In this case, the device may be electrically structured It is also simple, compact, and easy to handle.

For the arrangement of speakers as described above, the relationship between the audio track signal and the utterance content can be determined according to a predetermined correspondence depending on, for example, the stereo trunk, the presence or absence of the audio signal on the R track, or a combination thereof. generation of sound for the operating body, generation of sound for the corresponding video device, driving of a corresponding specific driving device, stopping of sound, or sensing of external sound and driving of the corresponding driving device, etc. Generate and take action.

In addition to sound generation and operation, light emission, lighting, and other operations may be performed.

By increasing the number of electrical connections, a large number of characters and dolls such as flowers and animals can be divided into groups and produced.

The image signal from the screen detection sensor causes the speaker (
During a predetermined period when no sound is emitted from the operating body (including for the operating body and for the video device), the sound sensor detects the sound of characters A and B in response to sounds from the outside, such as audience applause and calls.
If a predetermined drive device is activated to perform actions such as moving limbs, it will have a great effect on attracting the audience's interest.

Although the sound sensor is used to select the period in which it responds to external audio, it is not based on the control signal as described above, but rather when there is no audio signal on either the R or L stereo audio track, or when there is no audio signal. The selection may be made in accordance with a state or condition, such as a situation where a signal is present but no sound is generated due to the action of a muting circuit or the like.

〔Effect of the invention〕

The present invention uses a simple and easily available videotape to create an effect that makes it appear as if a dialogue is taking place between the characters or between the images by associating images on a video camera with characters. By using a VTR, the device becomes less expensive, the program is extremely simple to create, maintenance is easy, and it can be easily implemented at home or in a small group.
