Abstract

PURPOSE:To reduce the deformation of a rectangular magnetic sheet to improve the quality of reproduced sounds, by providing the start point and the end point of a track for a recording and reproducing head near edges on longer sides of the sheet. CONSTITUTION:A magnetic coating 2 is provided on the rear face of a rectangular sheet 1, and an orchestral accompaniment is preliminarily dubbed on a track 3 from a start point 4 to an end point 5 near edges of longer sides of the sheet. The head is pressed to the sheet 1 at the start point 4 and runs along the track 3 to reproduce sounds while raising and deforming the sheet partially, and the head is returned automatically from the end point 5 to the start point 4. The front face of the sheet 1 is a printed face, and a name and words of a song corresponding to the accompaniment on the track 3 are printed there.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is characterized in that it is partially deformed by being pressed by a recording/reproducing head.
A sheet recording body having a long side and a short side and having a start point and an end point of a track by the recording/reproducing head near the side edges of the long side, and the sheet has something corresponding to the track printed on its surface; The gist is that the printing coincides with the starting and ending points of the head, thereby making it possible to reduce deformation of the sheet, improve reproduction sound quality, and obtain a magnetic sheet suitable for repeated reproduction.

To describe an example of this implementation, as shown in Fig. 1, the back side of a rectangular sheet (1) is coated with a magnetic coating (2), and the karaoke accompaniment is placed at the starting point near the long edge of the sheet. Dubbing to track (3) from (4) to the end (5). The head presses against the sheet (1) from the starting point (4), partially lifting and deforming the sheet while playing along the track (3), and the head automatically moves from the ending point (5) to the starting point (4). The head returns to its original position and automatically stops at the starting point (4), which also serves as the end point of the head's travel. The surface of the sheet (1) is a printing surface (6) as shown in FIG. 2, and the name of the song corresponding to the track (3) and the song ll1i] (7) are printed on this surface, and the starting point of the head ( The accompaniment played from 4) to the end point matches the lyrics (7).

Figure 3 shows the magnetic coating surface (2) on the back side of the sheet (1).
), cross-dubbing the karaoke accompaniment track (8) and another karaoke accompaniment track (9), and on the front side (6) of this sheet, the back track is on the right half as shown in Figure 4. Titles and songs corresponding to (8) in (10
) and print the title and lyrics (11) corresponding to the trunk (9) in Figure 3 upside down on the left half.

To perform karaoke singing with this sheet, first place the sheet on top of the player with the title and lyrics (10) facing forward, as shown in Figure 4, and then turn the sheet into a karaoke (8). After playing the accompaniment and singing while reading the lyrics (10), turn the sheet (1) 180 degrees and place it on the player again. This time, while playing the trunk (9), read the lyrics (11). )
Sing while reading.

The apparatus for reproducing the sheet is as shown in FIG. 5, and has a sheet fixing frame (13) on the main body (12), and the lyrics on the sheet surface can be read within the frame, and precautions can be written within the frame. The turntable (14) has a radially moving head (15). The details of this were proposed separately by the present inventor and are patented, so they will not be described in detail here.

(16) is the playback start button, (17) is the speaker,
(18) is an amplifier.

However, an example with a slightly different circuit is shown in FIG.

That is, the singing voice enters the microphone (19) and goes to the echo circuit (
20), and the sheet's karaoke accompaniment is recorded in the head (
21), enters a preamplifier (22), is mixed with the audio by a mixing circuit (23), enters an amplifier (24), is magnified, and is output as karaoke accompaniment and singing from a speaker (25).

In the present invention, as described above, the start and end points of the head travel are near the long side edges of the sheet, so when there are letters, etc. on the sheet surface, the angle of deformation of the sheet due to head pressure contact is small, and the letters, etc. Easy to see. Furthermore, when the sheet is not used for a long period of time, the head stops at the end point and pushes the long side edges of the sheet, so there is little permanent deformation of the sheet.

Furthermore, when the head starts, the seat deformation angle is small, so the head starts smoothly and there is no sound dropout.
The speed of the head is also constant and good reproduction can be performed.

In addition, the present invention has various advantages, such as the fact that the start and end points of the head coincide with the beginning and end of the printed object, making it convenient when looking at the printed object and repeatedly listening to the reproduced sound. .

The present invention may be modified in various ways other than those described above, but all of these are included in the present invention.
