DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation device mounting structure for an electronic device for mounting an operation device for operating a switch on an operation panel.

[0002]

2. Description of the Related Art An operation panel of an electronic device such as an electronic musical instrument or an OA device is provided with a large number of controls and their display sections.

[0003] Conventionally, as an operator mounting structure of this kind of electronic equipment, a switch and an operator are both assembled on a substrate,
An operator that exposes the operator from the operator opening of the operation panel, or a switch with only the switch attached to the board, and the operator is inserted into the operator opening of the operation panel and protrudes by the elasticity of the switch. Etc.

However, in the above-mentioned operation element mounting structure, it is difficult to accurately arrange the operation elements on the board in the former case, so that the gap between the operation element opening of the operation panel and the operation elements becomes uneven. In the latter case, there is a drawback in that the operating element guide member is only the plate-shaped operating element opening, so that the operating element is inclined when the operating element is pressed, and the operational feeling is not good.

In order to solve this problem, for example, Japanese Utility Model Application
As disclosed in Japanese Patent Application Laid-Open No. 129237, an operator mounting structure in which an operator unit having an operator mounted on an operator frame is mounted on an operation panel has been proposed.
A lens body that guides light is provided on the operator frame, and a chip-shaped LED that is a light-emitting body directly mounted on a substrate.
This light is guided through the lens body to a lens body opening, which is a light emitting display unit provided on the operation panel, and a retaining portion for attachment to the operation panel is integrally formed on the operation element frame.

[0006]

However, in such a conventional operation device mounting structure for an electronic device, the lens body is fixed to the operation device frame, whereas the chip LED is mounted on the substrate. Since it is directly attached, the mounting error between the board and the operation panel is added to the mounting error between the operator frame and the operation panel, and many LEDs and the lens body are all or partially displaced. There is a risk. As a result, there is a problem that the luminance of the light-emitting display portion visually recognized from the end face of the lens body is extremely low or uneven.

Further, the lens body must be formed separately from the operator frame after being formed separately from the operator frame, or formed of a different material by two-color molding, and attached to the operator panel by the operator frame. Since the retaining portion is formed at the time, not only the production cost is increased, but also the assemblability and the maintainability when attaching and detaching the operator frame are difficult. Furthermore, conventionally, there has been a drawback that the combination with the operator, the frame, and / or the operation panel does not work well, so that mechanical noise is generated at the time of operating the operator, and the sense of quality is impaired.

The present invention has been made in view of the above points, and has a bright and uniform luminance of a light emitting display portion viewed from an end face of a lens body, and has good assembling workability and maintainability. It is another object of the present invention to provide an operation device mounting structure for an electronic device with a good operation feeling.

[0009]

According to the present invention, as shown in FIG. 1, an operator frame 20 for slidably mounting an operator 10 for operating a switch is provided.
In the operation device mounting structure of the electronic device in which the lens body 21 for guiding the light from the light-emitting body to the outside and disposed on the operation panel 70, the operation device frame 20 is positioned on the operation panel 70. Lock members 71a and 71b to be fitted are provided, and the operating member frame 2 locked by the lock members 71a.
An object of the present invention is to provide an operation device mounting structure for an electronic device in which a lens body 21 is applied to at least a part of a locked portion 0.

[0010] Further, the present invention also provides the same configuration as described above, wherein at least a part of the locked portion of the operation member frame locked by the locking member of the operation panel is filled with a portion near the lens body.

[0011]

[0012]

According to the above-mentioned structure of the operation device mounting structure for an electronic device according to the present invention, the operation device frame 20 can be locked only by press-fitting the operation device frame 20 into the operation device mounting portion of the operation panel 70. Locking member 71 provided on operation panel 70
a and 71b are firmly locked by frictional force. Conversely, the operator frame 20 can be pulled out from the operation panel against the frictional force to remove the operator frame 20 for defective product replacement or the like, so that maintainability is good.

When the operator frame is mounted, the side surface of the lens body 21 is regulated and locked by the locking member 71a of the operation panel 70, so that the positional relationship between the lens body 21 and the operation panel 70 is extremely high. High accuracy is maintained. Therefore, if the positional relationship between the light-emitting body and the operation panel is set accurately, the position of the light-emitting body and the lens body 21 will not shift, and the brightness of the light visually recognized from the light-emitting display unit on the end face of the lens body 21 will be dark. There is no risk of becoming irregular or uneven.

[0041]

As described above, in the operation device mounting structure for an electronic device according to the present invention, the lens body is provided on the operation device frame on which the operation device is slidably mounted, and is fitted by the locking member of the operation panel. In order to attach the controls to the control panel, it is only necessary to press-fit the control unit consisting of the control frame with the controls to the specified position on the control panel. is there. On the other hand, the operator unit can be extracted only by pulling it out from the operation panel against the frictional force with the locking member, so that maintainability is also good.

Since the lens body is applied to at least a part of the locked portion of the operator frame locked by the locking member of the operation panel, the positional relationship between the lens body and the operation panel can be extremely high. Will be retained. Therefore, by accurately setting the positional relationship between the operation panel and the luminous body, the position of the luminous body and the lens body does not shift, and the luminance of the luminous display section emitted from the end surface of the lens body becomes dark or uneven. There is no danger.

Further, even when the lens body is directly locked and the portion close to the lens body is used as a part of the locked portion, the positional relationship between the lens body and the operation panel is maintained with high accuracy. Also in this case, the luminance of the light emitting display unit can be kept uniformly bright.
