Description

Description: FIELD OF THE INVENTION The present invention relates to an operator casing that gives an indication of the operating state of a device.

[Prior Art] Since an operating device such as a remote control device is generally fixed to a wall, a thin casing is used, and the operating device is provided with a plurality of instructions for operating the device. Switch and a display element such as a light emitting diode for displaying the operating state are provided, a signal is sent to the control device according to the switch operation, and the light emitting diode lights up and displays according to the operating state.

In this case, the casing of the operating device is provided with a push button for pushing the movable part of the switch, and the switch inside the operating device uses a snap action mechanism with a repulsive force to return the push button to the original position. Has been done.

Further, the display opening of the light emitting diode for displaying the operation state is provided in the vicinity of the push button for pressing the switch associated with the display content.

[Problems to be Solved by the Invention] As described above, in the related art, since the casing of the operating device is fixed to the wall, a large thickness cannot be taken, and only the repulsive force of the switch provided in the operating device is used. Since the push button is returned to its original position, when the push button is pushed, the push button can move only the movable width for switching the snap action mechanism. Therefore, when the push button is pressed, the switch is actuated immediately, and it is difficult to obtain the feeling that the switch has been operated, and the operation feeling is poor.

In order to improve such a point, it is possible to integrally form a push button having a leg portion and a casing, and improve the operation feeling of the push button by the elasticity of the resin forming the casing.

However, in this case, in order to reliably move the push button to the inside of the casing and to prevent the connection portion between the leg portion and the casing from being damaged, it is necessary to secure the leg portion to a certain length. .

Therefore, much of the surface area of the casing must be used for the legs and, in this case, both the push button and the legs must be properly arranged within the limited area of the casing surface. It becomes difficult to provide the light emitting diode for the display related to the switch near the push button for operating the switch. In addition, the arrangement of multiple light emitting diodes is not close to the push button because of the display content of each,
When it is preferable that the plurality of light emitting diodes are arranged at positions close to each other, it is difficult to provide the plurality of light emitting diodes in an appropriate arrangement relationship.

According to the present invention, in the operating device casing, the operating feeling is improved without increasing the thickness of the operating device, and the operating device casing in which the light emitting element for displaying in relation to the operated switch is arranged at an appropriate position. The purpose is to provide.

[Means for Solving the Problems] The present invention has a control panel molded of resin, a switch for issuing an operation signal to a control device for controlling the device, and the device according to the operation of the switch. In a controller casing in which a display element for displaying the control state of is arranged on the back side of the operation panel, a push button for operating the switch and two push buttons for elastically supporting the push button on the operation panel. The technical means is to provide the operation panel with a separation groove for integrally forming the leg portion on the operation panel surface, and to provide a display opening of the display element between the two leg portions.

[Operation] In the present invention, the operation panel of the operation device casing is separated by the separation groove, and a part of the operation panel serves as a push button and a leg portion for operating the switch. Therefore, the push button smoothly moves to the inside of the casing by the elasticity of the resin forming the legs when the switch is operated, and acts on the movable portion of the switch.

In this case, in order to obtain appropriate elasticity during operation with the legs, it is necessary to lengthen the legs to some extent, so if these are integrally molded with the casing, many parts of the surface of the casing will be removed. It is used for pushbuttons and legs, reducing the area of the casing surface that is not related to pushbuttons.

Therefore, although the place where the display opening is provided is limited,
Since the display opening of the display element is provided between the legs, the light emitting element associated with the operated switch can be arranged close to the push button. Therefore, the push button and the display element can be associated with each other so that they can be arranged easily.

[Effect of the Invention] In the present invention, since the push button is supported by utilizing the elastic force of the resin forming the casing, it is possible to improve the operation feeling without increasing the thickness of the operation device.

Also, the casing requires legs to support the pushbuttons, reducing the available surface area elsewhere,
Since the display opening of the light emitting element is provided between the legs, the display can be performed at a position where the relationship with the switch can be understood as in the conventional case.

In addition, when the push button and the corresponding display opening are not arranged close to each other and it is necessary to arrange a plurality of display openings in close proximity to each other in relation to another display element, the leg portion By arranging the display openings between the display openings, the display openings can be set relatively freely, so that the display openings can be easily seen.
