Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cover for accommodating various kinds of certificate documents such as a gem certificate, a gem identification certificate, and a certificate of guarantee in a spread manner.

[0002]

[Prior art]

 Conventionally, a cover used for storing certificates has been proposed. The conventional structure of a conventional cover is simply a flat bag shape, one side of which has a mount and the other side of which is made of a transparent film, and the certificate is housed in the bag. Also, in order to enhance the taste, a music box or other sounding device is also proposed as a cover for transmission.

[0003]

[Problems to be solved by the device]

 However, the mere bag-shaped one as in the above-mentioned conventional one has no problem in the storage performance of the certificate, but has no intention and has a drawback that it is not interesting. In addition, the structure in which the music box is attached has a drawback that the structure has a thickness of several cm and is bulky when stored.

In view of the above points, the present invention intends to provide a cover for a certificate that has a melody when the cover is opened, is thin and is not bulky, and has a wide range of taste and practicality. Is.

[0005]

[Means for Solving the Problems]

 The technical means of the cover of the present invention comprises a cover main body capable of holding a certificate on the inner surface thereof and freely foldable at the central fold, and an electronic sounding device. A light receiving sensor that senses light when opened, an integrated circuit that reproduces the stored music by the signal from the light receiving sensor, a piezoelectric element connected to the integrated circuit, and a resonance plate that resonates by the vibration of the piezoelectric element. This sounding device is embedded in the main body of the cover.

[0006]

[Action]

 The cover of the present invention can be folded in two at the central fold, and the certificate is held on the inner surface thereof. Therefore, when the cover is opened to view the certificate, the outside light enters the inside of the cover and the electronic sounding device is exposed to the light. Since the light is shielded when the cover is closed, the electronic sounding device does not receive external light.

The electronic sounding device has a light receiving sensor, which is activated when exposed to light and sends a signal to the integrated circuit. A music is recorded in the integrated circuit, and this music is reproduced when a signal from the light receiving sensor is received. The reproduction of music in the integrated circuit is given as a voltage fluctuation, which causes the piezoelectric element to vibrate. This vibration is amplified by the resonance of the resonance plate and becomes a sound. Although a sound volume sufficient for listening can be obtained only with the resonance plate, in the present invention, since the sounding device is embedded in the cover body, the core material of the cover body promotes resonance and the sound becomes even higher.

[0008]

【Example】

 An embodiment of the cover of the present invention will be described with reference to the drawings. Reference numeral 1 denotes a cover body, which has a fold 2 in the center and can be folded in two. The cover body 1 is slightly thick and has a thickness of about 5 mm, and has a structure in which a core material such as cardboard is placed and the outer surface is covered with a synthetic resin film or the like. Transparent pockets 3 are provided on both side edges of the inner surface of the cover body 1, and both edges of the certificate A are put in the pockets 3 to fix and hold the certificate A on the cover body 1. Therefore, by opening the cover body 1, the certificates can be seen.

Reference numeral 10 denotes an electronic sounding device, which is embedded in a part of the cover body 1 so as to be embedded therein. As shown in FIGS. 2 and 3, this sounding device 10 comprises an integrated circuit 11 for generating a melody, a piezoelectric element 12 made of ceramics, a light receiving sensor (CDS) 13, a thin battery 14, a resonance plate 15 and the like. . In the integrated circuit 11, an appropriate music piece associated with the certificate to be accommodated is recorded, and when a signal is received from the light receiving sensor 13, the music piece is reproduced and transmitted to the piezoelectric element 12 in the form of voltage change. The piezoelectric element 12 vibrates due to the transmitted voltage fluctuation, and this vibration is amplified by the resonance of the resonance plate 15 to become a sound.

The generation of the melody is automatically stopped when one melody ends, the melody does not repeat, and the melody does not flow until the next signal from the light receiving sensor 13. It is also possible to attach a switch mechanism to stop the sound generation with the cover open. As this switch mechanism, for example, a circuit that automatically stops when a switching signal is continuously sent from the sensor 13 is incorporated in the accumulation circuit 11, and the cover is exposed two or three times. It is also possible to stop sounding by opening and closing quickly.

When the light receiving sensor 13 senses external light, it sends a signal to the integrated circuit 11. That is, when the cover main body 1 is folded in half, external light does not enter the inner surface of the cover, so the sensor 13 does not detect light reception, and only when the cover main body 1 is opened, light reception is detected. The surface coating film of the cover body 1 and the certificate A 1 are present outside the light receiving sensor 13, but both transmit light to some extent, and therefore their presence does not affect the sensing operation of the light receiving sensor 13. If the certificate A is in the form of a book having several pages, it is difficult for light to pass through. In this case, a watermark is put on the paper material of the certificate A to allow light to easily pass through. To do so. In addition, at the time of shipment, a light-shielding sticker such as silver paper is attached to the surface of the sounding device 10 so that the sounding device 10 does not emit noise due to inadvertent light sensing.

It should be noted that the present invention is not limited to the above-described embodiments, and can be freely modified and implemented within the scope of the claims for utility model registration. In particular, the structures and types of the integrated circuit 11, the piezoelectric element 12, the light receiving sensor 13, and the resonance plate 15 of the electronic sounding device 10 are not specified, and commercially available ones are freely selected according to the design purpose and adopted. It is possible.

[0013]

[Effect of device]

 With the cover of the present invention, since the melody plays when the cover is opened, it is possible to improve the value of the certificate contained in the cover and it is highly commercialized. In addition, the sounding device is an electronic type and has a smaller thickness than the conventional music box type, so it can be completely embedded in the main body of the cover, and it looks like a normal cover, so it can be opened. It can be given to those who see the unexpectedness and the surprise that it makes a sound. Furthermore, the cover of the present invention has advantages in practical use such as a simple structure and inexpensive manufacturing.
