Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a hand-operated organ (commonly called a street organ) that reproduces a tonal sound by inputting the obtained electric signal to a music playback device by reading the perforated paper that recorded sound by hand and sending it on the street or indoors. Regarding

[0002]

[Prior art]

 In the part that reads the hole of the conventional perforated paper in which the sound of the hand-worn organ is recorded, the electrode biased by the spring from above the perforated paper comes into contact with the flat plate-shaped electrode provided below the perforated paper at the hole. Then, the power was turned on and the recorded sound was read. However, in this method, the upper electrode is always in contact with the surface portion other than the holes of the punched paper, so that the paper is easily worn away, the punched paper is required to be thick paper, and the durability time was short. In addition, this contact causes resistance when feeding the paper, so the rotation of the handwheel was slow. Since the sound is read by the contact of the electrodes with each other, in the case of a short sound, the small holes did not make contact when the paper feed was fast, and the sound was sometimes lost because the signal was not input to the music playback device. If left unused for a while, the electrode may oxidize, resulting in poor contact, and the sound may not be reproduced.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is to solve the above-mentioned problems, to eliminate the wear of punched paper, to use punched paper of various paper quality, to reduce the resistance, to rotate the handle by hand, and to read the sound. It is to provide a hand-worn organ that is reliable and does not cause a loss of reproduced sound.

[0004]

[Means for Solving the Problems]

 The configuration of the present invention which has solved such a problem is as follows. In a hand-worn organ that converts into sound and plays music, a light source that emits light that passes through the hole is provided above the passage of the punch paper, and a plurality of light receiving elements that read the light that passes through the hole are provided below the light receiving element. The signal of is converted into an electric signal through a conversion circuit, the electric signal is input to the music reproducing device, and a detector is provided in the passage in front of the light receiving element to detect the punched paper and operate the electric circuit. Organ 2) As the light source, a plurality of LEDs are arranged in a row in the width direction of the flash paper, and a black cover is formed on the light receiving element of the passage to open a plurality of holes for guiding light to each light receiving element. Installed The hand-worn organ described in 1) above. As the light source of the present invention, an LED, a light bulb, a surface light emission or the like is used. The punched paper on which the sound is recorded is usually a folded long cardboard, but roll paper or plain paper punched and wound may be used.

[0005]

[Action]

 In the hand-wound organ of the present invention, when the perforated paper on which music is recorded is turned by hand and the perforated paper comes into contact with the detector on the perforated paper passage, the electronic circuit including the light source and the music playback device is turned on. To When the perforation paper continues to feed and the perforation paper passes through the reading part, the light from the upper light source, especially the light from the LED in the configuration using the LED as the light source, passes through the perforation paper holes to the respective lower holes. Reach the corresponding light receiving element. Since the scale is determined by the position of the hole in the punch paper width direction and the length of the sound is determined by the length of the hole in the feed direction, the light receiving element corresponding to each hole receives the information of the hole and the conversion circuit uses the electrical information. It is converted into a signal and input to the music reproducing device. The music reproducing device processes the received electric signal to reproduce music.

FIG. 10 is an explanatory diagram showing an operating state, and FIG. 10 is a circuit diagram of the reading unit of the embodiment. The hand-worn organ 1 of the present embodiment is provided with a passage 4 for a punched paper 20 on which music is recorded on the upper part of a housing 2 provided with a folding lid 3, and a reading section 5 of a hole 21 and a hand-turning handle 15 are provided in the middle thereof. A feed roller 16 to be driven is installed. The reading unit 5 is rotatably attached to the side wall of the passage 4 by a hinge and is locked by a fixing bracket 14. The upper light source device 6, the light receiving device 9 embedded in front of the feed roller 16 in the passage 4, and the light receiving device Along with the device 9, it comprises a microswitch 13 as a detector that senses the presence or absence of the punching paper 20 by contact with the punching paper 20. Among them, the light source device 6 is provided with one LED 7 as a light source corresponding to each hole 21 of the perforated paper 20, and is located just above the feed roller 16 and is urged downward. A pressure roller 8 is attached which sandwiches the punched paper 20 with the feed roller 16 and pressurizes it to ensure the paper feed. Further, the light receiving device 9 is provided under the black cover 10 having holes 11 corresponding to each hole 21 of the perforated paper 20 just below the LED 7, and similarly, one light receiving device corresponding to each hole 21 is provided. The phototransistor 12 is arranged as an element. On the other hand, inside the housing 2, a conversion circuit 18 for converting a change in light sensed by each phototransistor 12 into ON-OFF of an electric signal, and a known music reproducing device for reproducing music according to the electric signal input. 19 and a battery as a power source are provided. On both side surfaces of the housing 2, holding stands 17 for holding the punched paper 20 before and after passing through the upper portion of the housing 2 are attached so that the amount of withdrawal from the housing 2 can be adjusted.

After placing the punching paper 20 on the holding table 17 at the entrance side of the passage 4, the fixing metal fitting 14 of the reading section 5 is pulled to unlock the light source device 6, and the light source device 6 is raised. If the introduction part of the punching paper 20 is placed on the feed roller 16 and the light source device 6 is lowered and locked again, the micro switch 13 senses the punching paper 20 and turns on the power, and the LED 7 emits light and can be read. The state is entered and preparation is completed. When the perforated paper 20 is fed by turning the handwheel 15, and when the hole 21 reaches the positions of the LED 7 and the phototransistor 12, the light from the LED 7 passes through the hole 21 and also the hole 11 of the cover 10 and passes through the phototransistor 12 Received at. While the phototransistor 12 receives light, an electric signal flows through the conversion circuit 18, and an ON signal for reproducing the sound corresponding to the hole 21 is input from the conversion circuit 18 to the music reproducing device 19. The music reproducing device 19 reproduces a musical sound according to each input obtained by sending the perforated paper 20 by the handwheel 15 and can play the music recorded on the perforated paper 20. The perforated paper 20 that has passed through the reading unit 5 and has emerged to the outside of the housing 2 is supported by the holding table 17 below and collected. The hand-worn organ of this embodiment may be used by increasing or decreasing the number of perforated paper holes and the number of corresponding LEDs and phototransistors according to the scale to be reproduced.
