Marking for detecting the forward end is indicated at the upper right end of the transparent vinyl fixed to the supply reel 100, marking for detecting the reverse end at the upper left end of the transparent vinyl 201 fixed to the winding reel (140) do.

According to the configuration of the control circuit shown in Figure 4 will be described the operation of the device for automatically turning over the score according to the present invention.

First, when the player inputs AC 220V power to the control circuit 190, the AC primary 220V is excited through the circuit breaker (NFB: No Fuse Breaker), and AC 12V is induced by the transformer winding ratio.

The alternating current 12V passes through the full-wave rectifying bridge diode 310 to be a direct current 12V, and the direct current 12V is supplied to the control power supply of the control circuit.

The foot switch 200 and the foot switches 320 and 330 operate in an electrical or pneumatic manner.

When the player presses the left pedal L of the foot switch 200 shown in FIG. 2, the contact point of the foot switch L 320 is turned on, and when the left foot pedal L is released, the foot switch L is pressed. The contact of 320 is turned off.

The right pedal R of the foot switch 200 also performs the same operation as the left pedal L. FIG.

When the player presses the left pedal L of the foot switch 200, when the contact of the foot switch L 320 is turned on and the relay 340 is excited, the alternating current flows through the excited relay 340 contact R1. Flows in the forward direction to the motor 180.

When the motor 180 rotates in the forward direction, the rotational force of the motor 180 is rotated in the forward direction through the gear unit 170 fixed to the motor shaft. The new sheet music is moved to the left and positioned at the center of the main body 99, and the previous sheet music is wound on the reel 140.

Even if the foot switch (L) 320 is turned off by restoring the left pedal L of the foot switch 200, the motor 180 continues to rotate and the sheet music is finished, and the transparent vinyl 201 is detected by the sensor X _A. When the motor stops spinning.

When the foot switch 320 and 330 are interlocked with the foot switch 200 and press and release the foot switch 200 once, the foot switch 200 returns to its original position by elastic force such as a spring provided in the foot switch 200. At the same time, the contacts of the scaffolding switches 320 and 330 are attached and dropped.

When the contact of the foot switch (L) 320 is closed, the relay 340 is excited and the motor 180 rotates in the forward direction. After that, the detection unit 120 detects a musical score and the sensor X _A is closed. Even if the contact of L) 320 is opened, the contact point R _1A is closed by the self-holding force of the relay 340.

The relay 340 is excited because the contact point R _1A and the sensor X _A are closed.

When the detector 120 detects the score, the sensor X _A is closed, and when the detector 120 detects the transparent vinyl 201, the sensor X _A is opened.

Regardless of whether the sensor X _A is closed or opened in the initial state, the operation of the relays 340 and 350 through the foot switches 320 and 330 continues the motor 180 until the detection unit 120 detects the transparent vinyl 201. Rotate

At this time, when the sheet music is moved by one sheet and the detector 120 detects the transparent vinyl 201 instead of the sheet music, the sensor X _A is opened and the relay 340 loses its self-holding power and the motor 180 is stopped.

The contact point R _2B opens when the relay 350 is excited and closes when the relay 340 is excited, thereby protecting the motor 180 by always operating any one of the two relays 340 and 350.

The operation of the foot switch (R) 330 is also the same as the operation of the foot switch (L) (320).

In addition, when it is necessary to continue playing the sheet music by playing at a constant speed, if the player keeps stepping on the left pedal L of the foot switch 200, the contact point of the foot switch L 320 is still attached. Since the relay 340 is excited and the motor driving current through the wiring breaker continues to flow through the relay 340 contact R1, the motor continuously rotates in the forward direction and the sheet music of the supply reel 100 continuously moves to the left. It is wound around the winding reel 140.

     Then, when the forward end detection mark is sensed at the moment when all the scores of the supply reel 100 are wound on the reel 140, the operation of the motor 180 is stopped and the supply reel 100 is stopped.

Forward or reverse end detection stops the operation of the motor 180 by using a sensor or by detecting a motor stall current.

2 detects the detected part of the transparent vinyl 201, and when the detected signal is input to the control circuit 190, the control circuit 190 generates a motor according to the detected signal of the detected part. The position control of the 180 is performed, and the sheet music of the supply reel 100 moves to the point where the detected part of the transparent vinyl 201 containing the sheet music and the detecting part 120 coincide with each other and stops.

That is, since the detected part and the detecting part 120 are located in a straight line, the sheet music is located at the center of the main body part 99.

In addition, when the performance progresses at regular intervals and the intermission of the sheet music is required, each time the player presses the foot switch R 200 once, the sheet music is moved in the reverse direction (right side) by one sheet, and continues to be stepped on. If so, the score will continue to move in the reverse direction.

When the score of the winding reel 140 is all wound on the supply reel 100, when the reverse end detection mark is detected by the detection unit 120, the operation of the motor 180 is stopped and the supply reel 100 is stopped.

In addition, if the player presses the foot switch (R) 200 continuously, the relay 350 is excited and the driving current flows in the reverse direction to the motor through the contact point R2 of the excited relay 350, and the motor 180 is rotated. Rotates in the reverse direction, and the rest of the operation is the same as the forward rotation of the motor 180.

The capacitor 360 shown in FIG. 4 absorbs the ripple and surge voltage of the motor 180 and serves to protect the motor.

Although the invention made by the present inventors has been described in detail according to the above embodiments, the present invention is not limited to the above embodiments and can be modified in various ways without departing from the gist of the present invention.

As described above, according to the present invention, the player automatically turns the sheet music according to the present invention, when the player plays the music while watching the sheet music. The effect that convenience can be improved is obtained.

In addition, according to the device for automatically turning the sheet music according to the present invention, as the sheet music is not jammed when the sheet is turned over, the sheet music is turned one by one, thereby preventing mistakes caused by the sheet music being flipped over, thereby allowing the player to play comfortably.
