[Problem that the idea aims to solve] However, according to the conventional technology with the above-mentioned configuration, the button is located on both the panel and the housing. If the center of the through hole is misaligned, the pad will slide against the inner surface of the guide hole. There is a difference in level between the panel and the housing, which causes the buttons to get caught and prevent smooth sliding movement. There was a problem that In addition, as shown in Figure 3, buttons such as large width buttons and slide switch knobs can also be used. If you try to handle a wide variety of items other than panels in the same casing, the difference between the panel and the casing. Two types of molds have to be made for each product, which increases costs. There was a problem. In view of the above problems, the present invention eliminates the step on the inner surface of the guide hole, making it easier to slide the button. The button guide mechanism prevents interference with movement and improves button operability. The purpose is to provide. Furthermore, the present invention has a configuration that can be used for a wide variety of products without changing the shape of the housing. The aim is to support a wide variety of products at low cost.

[Means to solve the problem]

In order to achieve the above purpose, the present invention is designed so that the button contacts only the panel. Ru. Furthermore, the through-holes in the casing are set relatively loosely, and detailed guides for each product type are provided. The position of the holes should be set only on the panel. In other words, the present invention provides a device for installing push buttons or slide knobs. Attach a panel made of separate pieces to the surface of the casing, and make the panel and the casing face each other. A through-hole is created at the position where the through-hole is located, and the through-holes in the panel and the housing are overlapped to form one guide hole. Insert the push button or slide knob into this guide hole. In the button guide structure that , characterized in that a rib is formed protrudingly to fit into the through hole of the casing opposite to this. .

[0005]

[Effect]

With the above configuration, the present invention allows the button to be inserted into the rib of the panel that fits into the through hole of the housing. It only touches and slides. In addition, the ribs on the panel guide the buttons, allowing the through-holes in the housing to accommodate various widths. If you set the shape so that the ribs fit together, you only need one shape of the casing, and then the rest. can be used for a wide variety of products just by modifying the panel.
