Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a storage board opening/closing device for an electronic musical instrument.

Conventional technology In recent years, electronic musical instruments such as electronic keyboards transmit and receive various performance statuses as digital signals.
With the advent of keyboards with MIDI terminals, instruments are increasingly being used in combination.

An example of a conventional electronic musical instrument such as an electronic keyboard will be described below with reference to the drawings.

FIGS. 11 and 12 show an example of a conventional electronic musical instrument. In Figure 11, 1 is the top plate, 2
is an electronic keyboard installed on the top plate 1. In Fig. 12, 1 is a top plate, 2 is an electronic keyboard, 3 is a storage stand attached to the top plate 1,
An electronic keyboard 2 is mounted.

Problems to be Solved by the Invention However, in the above configuration, in order to mount the electronic keyboard 3,
The depth of the top plate 1 or the storage stand 3 increases in order to place the tabletop 1 or the storage stand 3 in a stable state, resulting in the following problems.

Electronic musical instruments have a large external shape, making them inconvenient to carry and requiring a large storage space.

As the external shape becomes larger, the amount of packaging required increases and transportation costs increase.

The external shape has a large depth and lacks smartness in terms of design.

The present invention solves these conventional problems and provides a storage board opening/closing device for an electronic musical instrument that has a reduced cabinet depth and a smart design.

Means for Solving the Problems In order to solve the above problems, the electronic musical instrument of the present invention connects the rear end of the top plate and the rear end of the storage board provided on the top surface of the top plate by a rotatable connecting means. Usually, the storage board is placed on the top surface of the top board, and when this storage board is opened during use, the top surface of the top board and the back surface of the storage board are held in an almost horizontal state around the rotational fulcrum of the connecting means. This is what I did.

Function: With the above-described configuration, the storage board of the present invention can be used as a storage stand when opened, and when the storage board is closed, the depth of the cabinet can be reduced.

Embodiment A storage board opening/closing device for an electronic musical instrument according to an embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view of a connecting means of a storage board opening/closing device according to an embodiment of the present invention. 4 is the support arm, 5
is a support arm, and 6 is a fulcrum shaft. FIG. 2 is an installation perspective view of the connecting means. In FIG. 2, 7 is a storage board, 8 is a connecting means attachment screw, and 9 is a finished product connecting means. The connecting means 9 has a structure in which the supporting arm 4 and the supporting arm 5 are connected by a fulcrum shaft 6, which is attached to both end sides of the top plate 1 and the storeroom board 7 with screws 8.

The operation of the storage board opening/closing device for an electronic musical instrument constructed as described above will be described below with reference to FIGS. 3, 4, and 5.

FIG. 3 is a partial side view of the connecting means 9 when the storage board is closed. FIG. 4 is a partial side view of the connecting means 9 with the storage board opened. FIG. 5 is a partial plan view of the connecting means 9 with the storage board opened. In FIG. 3, 4a is a stopper portion of the support arm 4, and 5a is a stopper portion of the support arm 5.
4 and 5, when the storage board is opened, the stopper portions 4a and 5a come into contact, and the connecting means 9 is supported substantially horizontally. The entire situation is shown in FIGS. 6 and 7.

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

FIG. 8 is a perspective view of the second embodiment of the present invention with the storage board in an open state. In the same figure, 1
7 is a top plate, and 7 is a storage board, which is the same as the configuration shown in Figure 2. The structure differs from that shown in FIG. 2 in that a rotatable hinge 10 and a support member 11 for maintaining the horizontal position are provided instead of the connecting means 9 having a pivot point and a stopper.

The operation of the storage board opening/closing device for an electronic musical instrument constructed as described above will be described below with reference to FIGS. 9 and 10.

FIG. 9 is a partial side view of the second embodiment with the storage board in a closed state. FIG. 10 is a partial side view of the second embodiment with the storage board opened. 9th
In the figure, 10 is a hinge and 11 is a support member.
When the storage board 7 is closed, the support member 11 is housed in the main body of the electronic musical instrument. Figure 10,
When the storage board 7 is open, the support member 11 is pulled out from the main body side of the electronic musical instrument, and can support the storage board 7 in a substantially horizontal state.

Effects of the invention As described above, in the present invention, the rear end of the top plate and the rear end of the storage board provided on the top surface of the top plate are connected by a rotatable connecting means, and the storage board is normally placed on the top surface of the top plate. When this storage board is opened during use, the top surface of the top plate and the back surface of the storage board become almost horizontal around the rotational fulcrum of the connecting means, and it becomes a storage stand. The depth of the external shape can be reduced, making it possible to downsize and increasing the degree of freedom in design.

In addition, the amount of packaging required is reduced, and transportation costs can also be reduced.
