Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mounts a keyboard on a desk mat of an underlay used for various desks, etc., so that school children at home etc. can easily and easily practice music at a desk. It relates to a desk mat with a keyboard instrument that is made possible.

[0002]

2. Description of the Related Art Conventionally, in this type of touch switch keyboard musical instrument desk mat, it is formed by two layers of an upper substrate and a lower substrate which are located under a transparent plate such as a plastic on the front surface. In some cases, a fitting recess for accommodating is provided, and a thin battery portion, a speaker portion, and an I / C portion are connected to the upper portion by a conductive wire. (See, for example, Japanese Utility Model Publication No. 4-42158)

However, this conventional example has a very low volume due to a thin speaker, belongs to toys and entertainment, and uses a small flat battery, so that the keyboard can be easily used for a long period of time. There is a problem that it is difficult to practice the pitch with the musical instrument, and it is very troublesome to replace the battery. Moreover, the keyboard itself cannot be made large due to the small battery, and it is not suitable for pitch education because it is made small.

[0004]

SUMMARY OF THE INVENTION The present invention has been made in view of the problems of the conventional technique as described above.
The purpose is to arrange a large keyboard section below the desk mat to ensure good volume, and to install a vertical storage box on the right side of the desk mat to install a large speaker section inside. A switch mat with a keyboard instrument that can be operated from the surface, easily and securely stores the power supply and the I / C section, and has a sound volume that does not break down over a long period of time and that is as good as a piano or organ. Is provided.

[0005]

To achieve the above object, in a desk mat with a keyboard instrument of the present invention, the desk mat comprises a mat section and a storage box. In the mat part, a cushion sheet is formed on the bottom and an insulating sheet is interposed on the bottom of the cushion sheet to superpose a conductor sheet on which ultrafine conductors are joined. A keyboard printing sheet on which a keyboard portion is printed is laminated on the upper portion of the conductor wire sheet, and a transparent sheet transparent to the upper portion of the keyboard printing sheet is superposed. Further, the storage box body is vertically mounted on the right or left side portion of the mat portion. Inside the storage box book, a speaker portion, a conductor sheet, and an IC portion are stored. The switch is provided so that it can be operated from the surface of the storage box.

[0006]

The present invention has the above-mentioned structure, and its usage will be explained below. The present invention is laid on a top plate such as various desks (20) shown in FIG. The matting part is used for writing in this state. Then, for example, when a learner practices a musical instrument on the keyboard (9), the DC jack tip portion (of the adapter (18), which is a power source, to the jack insertion hole (8) on the side surface of the storage box (2) ( 17) is inserted, electricity is turned on by operating the switch (5) on the front surface, and the keyboard portion (9) is pressed from the upper surface of the transparent sheet (12) to generate a volume from the speaker portion (7). , It is very convenient to use for music and learning.

[0007]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the drawings, an embodiment of the present invention will be described. As shown in FIG. 2, a desk mat (1) provided with a keyboard musical instrument is formed in a rectangular shape which is long in the lateral direction. It is constructed by assembling the mat part (3) and the storage box body (2) provided on either the left or right side surface of the mat part (3). The cushion sheet (10) made of the constituent material of the elastic body is positioned at the lowest portion of the mat portion (3).
A conductor wire sheet (14) obtained by joining ultrafine conductor wires (15) connected to respective keyboard parts (9) with various insulating sheets (13) interposed on the cushion sheet (10) is polymerized. is there. The keyboard sheet (14) is laminated with the keyboard printing plate (11) in various color patterns having the keyboard portion (9) printed on the upper surface thereof. The keyboard printing plate (11) has a transparent sheet (12) which is superposed and laminated so that the keyboard portion (9), which is a surface sheet, can be seen through.

Next, the storage box (2) has a rectangular shape in the longitudinal direction, and is installed in the longitudinal direction on either the left or right side of the mat section (3). The storage box body (2) is internally provided with a speaker section (7) and an I / C section (6) connected to the conductor wire (15) of the conductor wire sheet (14). Further, the storage box body (2) is provided with a switch (5) which can be opened / closed from the outside at a predetermined position. Also,
On the side of the storage box (2), the DC jack tip (1
A jack insertion portion (8) into which 7) can be inserted is provided. Reference numeral (16) indicates a storage portion for accommodating a pencil, a ballpoint pen, etc. provided on the upper surface of the storage box body (2).
8) shows an adapter connected to the DC jack tip portion (17), and (20) shows a desk for school children or the like on which the desk mat (1) is laid.

[0009]

Since the present invention is configured as described above, it has the following effects. That is, according to this desk mat with keyboard instrument,
It has the convenient effect that schoolchildren can use the writing work for learning in the same way as a conventional desk mat and can practice music while learning note symbols. In addition, the desk mat is free to move, and has the convenient effect that it can be used for writing and for learning music. This desk mat can be easily assembled and constructed by the mat part and the storage box body. Since the mat part uses an elastic cushion sheet at the bottom part, it is resilient to the pressing operation from above. Since it is possible to cope with this, there is an effect that the inner conductor wire and the conductor wire sheet can be protected securely and firmly. In addition, the mat part is composed of an insulating sheet on top of the cushion sheet, and a conductive wire sheet, a keyboard printing sheet and a transparent sheet on the top, which are superposed on each other. Is effective. Further, since the storage box is mounted vertically on either the left or right side of the mat, the length of the storage box is stored shorter than the one mounted on the upper end of the mat when it is rolled up and conveyed. There is an effect that is very convenient. In addition, the length of the conducting wire connected to the I / C portion located in the storage box is significantly shortened, which is also advantageous in economic advantage. Then, the storage box body has a practical effect such that the speaker portion, the I / C portion, and the switch for operation can be respectively housed or installed inside and miniaturized.
