Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a switch device for an electronic musical instrument such as an electronic organ.

BACKGROUND OF THE INVENTION In recent years, electronic musical instruments such as electronic organs have been required to have more functions as well as operation buttons that look good and have a good feel.

An example of a conventional switch device for an electronic musical instrument will be described below with reference to the drawings.

FIGS. 4 and 6 show an example of a conventional switch device for an electronic musical instrument. In FIG. 4, 1 is a front panel. One is a pin provided inside the surface spring /L/1. 2 is a comb-shaped button with multiple buttons connected without sagging to select functions.

Reference numeral 2A denotes a recess provided in the connecting portion of the button 2, and 6D is formed to fit into the pin 1A. 3 is a push switch. 4 is a printed circuit board equipped with an electric circuit and also equipped with a push switch 3.

The operation of the electronic musical instrument switch device configured as described above will be described below.

First, when selecting a function etc., the button 2 is pressed and the push switch 3 on the printed circuit board 4 is pressed to operate the electric circuit.

Problems to be Solved by the Invention However, with the above configuration, if the buttons 2 have to be arranged in a limited space, such as to enhance functionality and make it more compact, it may be necessary to arrange the buttons 2 closely together or in a narrow space. The conventional shape of the button 2, which is frozen in a comb shape to prevent the buttons 2 from interfering with each other, has the problem of being unreasonable, such as having to place the button 2 in a certain location.

The present invention solves the above problems, and provides an electronic musical instrument that maximizes the use of limited space with the buttons 2 connected, has a good appearance and feel, and is easy to assemble. A switch device is provided.

Means for Solving the Problems In order to solve the above-mentioned problems, the switch device for an electronic musical instrument of the present invention has a thin film with slack between the buttons when the buttons are inserted into the front panel. They are connected together and a printed circuit board with a push switch is attached.

Effects The present invention has the above-described configuration, which makes it possible to make the most effective use of limited space, such as in densely arranged button arrangements or button devices in narrow spaces, without deteriorating the appearance, feel, or workability. becomes.

Embodiment Hereinafter, a switch device for an electronic musical instrument according to an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows a cross section of a main part of a switch device for an electronic musical instrument according to a first embodiment of the present invention. FIG. 2 is an exploded perspective view. In FIGS. 1 and 2, 1 is a front panel. One is a pin provided inside the surface spring /L/1. 2 is a button in which a plurality of buttons are connected.

2A is a recess provided at the end of button 2, and pin 1
It is formed to fit into A. 2B is a U-shaped thin film connecting the buttons 2. 3 is a push switch, and 4 is a printed circuit board.

A switch device for an electronic musical instrument configured as described above will be described below with reference to FIGS. 1 and 2.

The recess 2A of the button 2 is inserted into one pin of the front panel 1, and the button 2 is attached at a predetermined position. and button 2
The printed circuit board 4 prepared so that the push switch 3 will be placed at the bottom of the board is fixed in place with a screw or the like using a surface spring)
Fix it to l.

In addition, in the embodiment, a U-shaped thin film 2B is placed between the buttons 2.
By connecting the buttons 2 to 2, the connecting portion of the button 2 can be made smaller and the space can be used effectively. Also, if the button 2 is made of an elastic material such as rubber, the U
The shape and effect of the character-shaped thin film 2B are combined, and when a button 2 is operated, the adjacent button 2 does not move, making it possible to improve the feel of the button.

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

FIG. 3 is a sectional view of a main part of a switch device for an electronic musical instrument showing a second embodiment of the present invention. In the same drawing, the configuration differs from that of the first embodiment in that the shape of the thin film 2B connecting the buttons 2 is changed.

(,) In the figure, the button pitch is increased when the button 2 is alone and is connected in a sheet shape. When the button 2 is inserted into the panel 1, the thin film 2B sag from a sheet shape to a U-shape, thus fulfilling the same role as in the first embodiment. This is a second example.

(b) In the figure, the shape of the thin film 2B connecting the buttons 2 is W-shaped, but it is not limited to the U-shape.

Effects of the Invention As described above, the present invention enables close arrangement of buttons by connecting the buttons with a thin film with slack when the buttons are inserted into the front panel. Increased flexibility in button layout (design) with increased functionality and compact design. Also, the buttons don't move, giving you a better feel.
