[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piano having electric means for playing such as an automatic piano.

[0002]

2. Description of the Related Art Conventionally, in a grand type automatic performance piano, as shown in FIG. 12, a piano operating device a, a power supply device b and the like are provided in a cabinet case d separate from a piano body c.
And a configuration in which a piano body c and a cabinet case d are connected by a cable e is known.

[0003]

[Problems to be Solved by the Invention] The above-mentioned operation device and power supply device housed in a cabinet case are:
The cabinet case is relatively large, and there is an inconvenience in taking up space for storage.In addition, the cost for creating the cabinet case is high, and a large cabinet case other than the piano is installed near the piano body, so the piano There is a defect that impairs the appearance.

An object of the present invention is to solve the above-mentioned inconveniences and drawbacks and to provide a piano which does not impair the appearance of the piano, requires no installation space, is inexpensive, and has good operability.

[0005]

According to the present invention, an opening is provided in a shelf of a piano body having electric means, and an opening for inserting a floppy disk is directed toward the front of the shelf in the opening. A floppy disk driver is installed so as to open, an operating device of the electric means is arranged on the lower surface of the shelf at a lower position of the floppy disk driver, and a power supply device for supplying power to the operating device is connected to a leg of the piano body. The above-mentioned object is achieved by housing and installing between the seat and the soundboard.

[0006]

[Function] The floppy disk driver is housed inside the shelf, and the floppy disk insertion opening is open toward the front of the shelf, so it is easy to replace the floppy disk when the music is changed. There is an operating device below it, so you can easily control the volume etc. during performance without disturbing the posture, and the heavy power supply unit on the leg holder and below the soundboard under the soundboard Because it is housed in the interior space, it does not impair the appearance nor the acoustic effect of the piano. Further, since no cabinet case is required for the control device and the power supply device, the appearance of the piano is not impaired, the installation space is not required, and the cost is reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 show a front view and a side view of an automatic performance type grand piano, in which a storage space 3 is provided at a right front portion of a shelf 2 constituting a piano body 1 and a floppy disk driver 4 is stored therein. On the lower surface of the shelf 2 and below the floppy disk driver 4, an operating device 5 such as a switch or a volume for operating electric means for playing is provided. A power supply device 8 for performance is provided on the sound board 7 and between the sound boards 7. The details of the accommodation space 3 are as shown in FIGS.
A front opening 10 communicating with the dug 9 is formed from the front surface of the dug 9, and the upper and lower surfaces of the dug 9 are closed by covers 11, 11, and an insertion slot 13 of a floppy disk 12 is provided therein. The floppy disk driver 4 was accommodated so as to face the front of the plate portion 2. The operation device 5
5 to 7 are attached to a hinge-shaped swinging member 15 which is swingably mounted below the insertion slot 13 of the floppy disk 12 and on the lower surface of the shelf plate portion 2 as shown in FIGS. When the swinging member 15 swings between an operation position in front of the shelf 2 as shown in FIG. 6 and a storage position along the lower surface of the shelf 2 as shown in FIG. Swings between the operation position and the storage position. The operation device 5 includes a display unit 16 and operation switches 17 in a thin case.
Are provided. Further, as shown in FIG. 11, the power supply unit 8 is provided on a chassis 20 fixed to the leg support 6 on a leg support 19 that supports the front leg 18 of the piano body 1. In addition to the transformer 21, the power supply circuit 22 and the like are assembled and installed. The cable indicated by reference numeral 23 in the figure is connected to an arithmetic circuit device such as a printed board (not shown) or an operating device 5 or a power receiving unit such as a floppy disk driver 4 housed in a shield case in a side plate of the piano body 1. The arithmetic circuit device is further connected to a floppy disk driver 4 by a cable extending, receives a signal input to the operating device 5 and a signal read from the floppy disk driver 4, and drives a piano driving device to perform. Is performed. The operating device 5 is shown in FIGS.
9 is attached to a slide member 24 provided on the lower surface of the shelf plate 2 as shown in FIG. 0, and the reciprocating movement of the slide member 24 advances the front of the shelf 2 shown in FIG. The operating device may be moved to the storage position along the lower surface of the shelf 2 as shown.

[0008]

[Effects of the Invention] As described above, in the present invention, the floppy disk driver is provided by opening the floppy disk insertion opening toward the front of the shelf plate at the opening provided in the shelf of the automatic piano body. Is installed, and the operating device is arranged on the lower surface of the shelf at the lower position of the floppy disk driver, and the power supply is stored and installed between the leg rest of the piano body and the soundboard, so it can be operated separately from the piano body There is no need for a cabinet case for the device and power supply, there is no inconvenience in taking up space for storage, the cost of the piano is low, the appearance of the piano is not impaired, and a good operability piano is obtained. There is.
