Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a keyboard-type electronic musical instrument in which an upper cabinet having a keyboard and a lower cabinet supporting the upper cabinet can be separated. It was made possible to do so.

Keyboard-type electronic musical instruments, especially spinet-type electronic organs, have become increasingly larger and heavier as their functions have been enhanced. On the other hand, this type of electronic organ can be enjoyed not only by being placed in a drawing room, etc., as in the past.
It has come to be often used for outdoor ball parties, etc., and has been frequently transported. However, as mentioned above, recent electronic organs are large and extremely heavy, so they have the disadvantage that they cannot be transported manually. ' In order to solve these inconveniences, the present invention makes it possible to separate the upper cabinet with the keyboard from the lower cabinet that supports it, making it easier to transport. This is to prevent damage to the cables and wiring.

An embodiment of the present invention will be described below with reference to the drawings.

In the figure, 1 is an upper cabinet with a keyboard, a tablet, and electric circuits such as a sound source circuit controlled by them (none of which are shown), 2 is a window provided on the rear surface 1a, and 3 is a window for opening and closing the window 2. A lid that can be freely covered; 4 is a stopper of the lid 3; 6 is a through hole provided in the bottom plate 1b of the upper cabinet; 6 is a wiring drawn out from the electric circuit;
7 is a binding tool for bundling the wiring 6 and fixing it to a part of the bottom plate 1b, 8 is a connector provided at the tip of the wiring 6, and 9 is a screw insertion tool formed near the through hole 5 of the bottom plate 1b. It is a hole.

On the other hand, 10 is a lower cabinet that supports the upper cabinet 1 and has electric circuits such as a circuit controlled by a foot keyboard and a speaker, and 11 is an upper panel 10 and 11 of the lower cabinet.
12 is a hole similarly formed near the through hole 11 of the top plate 101L, 13 is a metal substrate attached to the top plate 10 & so as to cover the through hole 11 and the hole 12, 14 is a connector fixed to the board 13, and 15 is a wiring connecting the connector 14 and the electric circuit inside the lower cabinet 10.

16 is a screw that passes through the holes 9 and 12 and is tightened into the screw hole of the board 13, and 17 is a washer for preventing the screw 12 from being removed.

In the above configuration, in normal use, the upper cabinet 1 is placed on the lower cabinet 1o as shown in FIG. 1, and the connectors 8.14 are connected. In this way, the upper and lower cabinets 1.1o are assembled together, and the electric circuits in each cabinet 1.10 are electrically connected to each other, so it can be used as a normal bassinet type electronic organ. be able to.

On the other hand, during transportation, the upper and lower cabinets 1.10 may be separated as shown in FIG. 2, and the connectors 8, 14 may be separated. In this way, each cabinet node) 1.10
The smaller size and lighter weight make it extremely easy to carry.

By the way, when separating the upper and lower cabinets 1.10, you must first remove the connector 8.14.'1
Must be. To remove the connectors 8 and 14, open the lid 3 and insert your hand through the window 2 of the rear panel 11L, as shown in Figure 2, but forget to separate the connectors 8 and 14. When the upper and lower cabinets 1 and 10 are separated, excessive force is applied to the connecting portion of the connectors 8 and 14, causing damage to the connector 8.14 and the connection portion between the wiring 6.15 and the electric circuit. be.

Therefore, in this embodiment, the connector 8.14 is fastened with a screw 16 in the immediate vicinity of the connecting portion, and the upper and lower cabinets 1, 1o cannot be separated unless the screw 16 is removed. If you do this, the upper and lower cabinets 1.
It is possible to reliably prevent the connectors 8, 14, etc. from being damaged when the connectors 10 are separated.

Moreover, in this embodiment, as is clear from FIGS. 3 to 6, a screw 16 is placed under the wiring 6. Therefore, if you want to remove the screw 16, be sure to remove the connector 8 beforehand.
You have to remove it and move the wiring 6 to the side. For this reason, forgetting to remove the connector 8.14 can be more reliably prevented.

Note that fasteners other than the screws 16 may be used.

As described above, the present invention provides a keyboard-type electronic musical instrument in which the upper and lower cabinets are separable, in which the electric circuits of the upper and lower cabinets are connected by connecting connectors provided at the ends of each wiring, and The bottom plate and top plate of the upper and lower cabinets near the connection point of the connector are fastened together using fasteners such as screws, and the upper and lower cabinets cannot be separated unless the fastener is removed, so the connectors must be removed. It is possible to prevent the situation where the upper and lower cabinets are separated without forgetting to do so, and it is possible to reliably prevent damage to connector connection points or damage to wiring.
