Description

[Detailed Description of the Invention] The present invention relates to an improvement of a musical score input device for inputting musical score information into a storage device of a music generator or the like.

In recent years, music generators and electronic devices for music learning using microcomputers have been developed.

However, in conventionally developed devices of this kind, input is based on switch inputs such as keys or keyboards, and when input is made by operating a switch, there is a drawback that no record is left of what kind of switch input was made. In addition, a corresponding switch mechanism is required on the equipment side, which has the disadvantage of complicating the device.

The present invention eliminates the drawbacks of the conventional device described above, and uses the interval entry field and note length entry field provided in advance on the staff to specify a note, and the designated note is optically read and recorded in a musical score. The device for forming input will now be described in detail with reference to the drawings.

FIG. 1 shows a recording medium 1 such as a tape or a card for recording music score input. A staff 2 is written in advance on the recording medium 1, and a clef such as a treble clef is written on the staff 2. The symbol is filled in
(There is.

On the staff to the right of the treble clef, there is a key information entry field 3 in which the treble symbol # and the flat symbol S are entered in their respective predetermined positions for inputting musical key information. A pitch entry column 4 and a note length entry column 5 are provided for inputting pitches.

Here, the interval entry field 4 and the note length entry field 5 are provided as a pair, and the interval entry field 4 is formed by arranging all notes in a vertical line on the staff from the highest note to the lowest note, while The length entry field 5 is provided to specify what type of note the interval information specified in the interval entry field 4 is. It is formed by filling in the type and type of rest.

That is, note information can only be provided when information is given to both the pitch entry field 4 and the note length entry field 5.

To write music information using Recording Body 1, first specify the key of the music you want to record by blacking out the # and b symbols provided in the key information entry column 3. Then, based on the note information of the music, mark all the notes in the predetermined interval of the whole notes provided in the interval entry field 4, and then specify what type of note the interval is. Specify whether there is a note by marking the corresponding note in the note length entry column 5.

Music information is recorded on the recording medium 1 in a state that can be read by an optical system by marking the interval entry field 4 and the note length entry field 5 in order according to the music to be recorded. Ru.

Furthermore, when recording a rest, it is not necessary to write in the interval entry column 4, and it is possible to record it only in the note length entry column 5.

The recording body 1 is provided with a synchronization signal entry field 6 for forming a timing symbol in correspondence with each of the above-mentioned information entry fields to ensure synchronization.

The recording medium 1 is set in a reading device equipped with a reading optical system, and is sequentially conveyed by power applied to a feed roller, and the reflected light from the light source reflected from the recording medium 1 is sent to columns in the information entry field. The information is read by a required number of correspondingly arranged light receiving elements and input to the music processing device.

In addition, the various information entry columns that are pre-printed or otherwise entered on the recording medium are printed in a pale color or a color that produces an output below the reading threshold so that the light-receiving element does not mistakenly read it as music information. There is.

FIG. 2 is a block diagram showing a storage device of a music processing device that reads and stores music information on the recording medium 1, and shows a light receiving element 7.
The read output detected by 1...In is converted from an analog signal to a digital signal by a converter 8, the converted digital signal is further converted into data by a decoder 9, and processing such as address designation is performed by a control circuit 10. It is stored in the corresponding area of memo 11.

When the control circuit 10 determines that the data has been stored at a predetermined address in the memory 11, a drive signal is output from the control circuit 10 to the driver circuit 12, and the step motor 13 is driven at a predetermined angle to drive the step motor 13 to the recording medium 1. Sync signal entry field 6
Since synchronization is not achieved, the note data in the next interval entry field or note length entry field is sent in a readable state.

By repeating the above operations, the musical score data recorded on the recording body 1 is sequentially recorded in the memory 11.

Information can also be recorded on the recording medium 1 by punching holes in the recording paper 1 at positions corresponding to the input information, instead of marking them.

As described above, according to the present invention, when storing music information, a recording medium with staffs etc. attached is used in the same way as musical scores, so input data can be created without changing the concept of writing musical scores when inputting information. This makes it easier to input data into music equipment, and it is also possible to record input data.

Furthermore, the reading device can use a reading sensor similar to the conventional one, and the structure of the input section of the music device can be significantly simplified.
