The present invention relates to an audio cassette mounting structure of a digital piano, and more particularly, an audio cassette for recording and reproducing a performance sound and synthesizing a performance sound with another musical instrument on a control panel of a digital piano. A cassette deck portion that can be mounted is formed.

In general, a digital piano is provided with a printed circuit board having various kinds of sounds stored therein, so that the pre-stored sounds can be generated according to an operation of pressing a switch having a keyboard shape.

Due to its characteristics, such a digital piano can be composed of various musical instruments, which can be combined with each other and played together, or equipped with an audio device such as a compact disc player (CDP). Holds.

However, such a conventional digital piano 10 is not stored or memorized during performance recording as the player does not have a function to record his own performance sound in addition to the function previously stored as shown in FIG. If you don't need the information, you have to use a separate audio set. In this case, it is difficult to accurately review your performance because it can be recorded with various noises. There was this.

The present invention is to solve such a conventional problem, by forming a cassette deck for mounting the audio cassette on the control panel of the digital piano, so that the audio cassette can be mounted and used if necessary, a separate audio set The new digital piano's audio cassette allows you to record and play back your own performance at the same time without using it, and to play along with the instrument sounds that are not built into the digital piano itself from the attached audio cassette. The purpose is to provide a mounting structure.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

The present invention, as shown in Figs. 2 and 3, to form a cassette deck portion 24 having an open top on the control panel 22 of the digital piano 20, the cassette deck portion 24 In the center of the rear wall of the power supply terminal 26 and the cassette drive terminal 28 protrudes, and both ends of the rear end is provided with an elastic member 32 to assist the eject (Eject) operation of the audio cassette 30 is mounted, An elastic eject piece 34 is formed on the front center of the deck portion 24, while a cassette deck portion cover 36 for a music stand is provided on the large troll panel 22 above the cassette deck portion 24. Has features.

As shown in FIG. 3, the guide ribs 38 for guiding the detachment and detachment of the audio cassette 30 are projected on the left and right walls of the cassette deck part 24 according to the present invention, and the audio cassette 30 is adapted accordingly. Guide grooves 40 are formed on the left and right sides of the.

Meanwhile, as shown in FIGS. 2 and 4, the cassette deck cover 36 widens the width of the cassette deck cover 36 so that the cassette deck cover 36 can be used as a music score, and the lower end of the cassette deck cover 36 is disposed on the control panel 22. Axially coupled from the bottom to open and close upward and downward by a manual method, and when the audio cassette 30 is mounted in the cassette deck 24, the tilt of the digital piano 20 In view of the fact that the front upper part of the audio cassette 30 protrudes upward, the audio cassette seating groove 42 is formed in the upper center inner surface thereof. It consists of a structure protruding the non-slip jaw 44 of a predetermined length to prevent the slip.

In the present invention, the power supply terminal 26 and the cassette driving terminal 28 protruding from the cassette deck part 24 are connected to the internal circuit of the power source and the digital piano 20 respectively, while the audio The elastic member 32 that assists the ejection operation of the cassette 30 applies a compression coil spring or a leaf spring.

The operation of the present invention as follows.

When the player wants to record his own performance or to play along with the music, rhythm, or instrument sounds recorded in the audio cassette 30, as shown in FIG. 4, the audio cassette 30 is controlled by the control panel 22. FIG. When fitted in accordance with the cassette deck 24 formed on the), the elastic member 32 is compressed by the force pushing the audio cassette 30 and at the same time the power supply terminal 26 protruding from the rear wall of the cassette deck portion 24 and Each cassette drive terminal 28 is fitted into each terminal insertion hole 46 of the audio cassette 30, and in this state, each function button of the audio cassette 30 itself is pressed to operate the audio cassette 30 in a desired state. You can play while playing.

In the case where the audio cassette 30 is to be ejected from such a state, when the eject piece 34 in the center of the cassette deck portion 24 is pressed, the audio cassette 30 is released from the mounted state and the cassette deck portion ( 24) is ejected while being pushed out by the restoring force of the elastic member 32 installed on both sides of the rear wall.

On the other hand, the audio cassette 30 described above may be stored in the cassette deck portion 24 without being ejected. In this case, when the cassette deck portion cover 36 is closed, the audio cassette is formed on the upper center inner surface thereof. The upper front part of the audio cassette 30 is accommodated in the groove 42 to store the audio cassette 30 without damaging the protrusion.

In addition, the cassette deck cover 36 may be used as a score in the lifted state, in which the sheet music is prevented by the non-slip jaw 44 protruding from the left and right sides of the control panel 22 around the cassette deck 24. Is to prevent slipping.

By applying the present invention, the audio cassette can be mounted on the digital piano itself, so that if the player wants to record his or her performance, it can be easily recorded and played without a separate audio set. There is an effect that can enhance the image of the product by persimmon.
