Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to an improvement of an operation panel, and particularly to an operation panel that provides a light operation touch.

[Background of the invention]

Conventional operation panels of this type include a movable piece of a board panel,
The gap between the operation sheet and the operation section was large, making it impossible to obtain a light operation touch. Incidentally, as this type of device, there is one described in Japanese Utility Model Publication No. 17701/1983.

[Purpose of the invention]

An object of the present invention is to provide an operation panel with a light operation touch.

[Summary of the invention]

In order to achieve the above object, the operation panel of the present invention includes an operation sheet, an operation section provided on the operation sheet, and a movable piece of a substrate panel that engages with the operation section. The device is characterized in that a protrusion integrally provided with the movable piece of the substrate panel is disposed corresponding to the operation section.

[Embodiments of the invention]

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is an enlarged view of a main part of an embodiment of the present invention, showing the relationship between a sombren switch unit hermetically sealed with a sandwich structure and a substrate panel. FIG. 2 is a plan view of FIG. 1. A circuit pattern having a plurality of fixed contacts 100 is supported on a base layer 102 or above, and an insulating layer 104 is provided on the base layer 102. Adhesive (not shown) is applied to both sides of the insulating layer 104.

It has a sandwich structure of the base layer 102 and the contact sheet layer 106. The contact sheet layer 106 is provided with cylindrical extruded parts 108 arranged corresponding to the fixed contacts 100 on the base 102, and the lower surface of the extruded parts 108 has the operating parts 1.
10 is wired.

Further, a substrate panel 112 is wired on the contact sheet layer 106, and an operation sheet 112 is provided thereon. and,
A plurality of movable pieces 116 integrally formed with the substrate panel 112 are provided at positions corresponding to the fixed contacts 100, and an operating protrusion 118 is provided at the center of the movable pieces 116. The acting force on the operation unit 120 integrated with the operation sheet 114 wired corresponding to the movable piece 116 of the board panel 112 is
The force is transmitted to the movable piece 116 of the substrate panel 112, the movable piece 116 integrally formed on the substrate panel 112 moves downward, and the operating force is applied to the extruded portion 108 of the contact sheet layer 106 by the operation protrusion 118, so that the operation contact 110 The contact of the fixed contact 100 is completed. Further, reference numeral 122 is a diode optical path, which is used to transmit light from a light emitting diode 50 (described later) onto the operation sheet layer 114. Also,
The substrate panel 112 and the operation sheet 114 are fixed and sealed with adhesive or the like. Therefore, the substrate panel 11
2, even if an acting force is applied to a part other than a certain operating unit, since the movable piece 116 is provided for each contact, other operating units are not affected and the contacts can be reliably opened and closed at the required positions. It is. Reference numeral 124 denotes a contact layer pressing portion, which includes the base layer 102, the insulating layer 104 and the contact sheet layer 10.
This is provided to ensure that the positions of the units No. 6 are in an appropriate relationship. In other words, the contact sheet layer 106 etc. are the substrate panel 1.
If it shifts upward on the 12 side, it will be pressed by the operation protrusion 118 of the board panel 112, preventing the operation contact 110 and the fixed contact 100 from coming into contact and completing a circuit regardless of the user's intention. . Here, 128 is a protrusion provided integrally with the movable piece 116 of the substrate panel 112.

When the operation sheet 114 is pressed,
In order to avoid feeling any elastic resistance, press the operating section 1.
28 has been established, but the result is.

A gap is generated between the operation sheet 114 and the board panel 112 that engages with it. Due to the gap,
The force acting on the operation unit 120 is applied to the operation point 110 because the operation sheet 114 itself is very resistant to touch sensation.
This increases the acting force that electrically opens and closes the fixed contact 100, making it impossible to obtain a light operating touch.
Therefore.

By providing the protrusion 128 on the substrate panel 112 as in this embodiment, the gap between the operation section 120 of the operation sheet 114 and the substrate panel 112 is eliminated, and the force acting on the operation section 120 is transferred to the substrate panel 112 by the protrusion 128. The substrate panel 112 is firmly and lightly attached to the movable piece 116.
The operating contact 110 is operated by the operating protrusion 118 of the movable piece 116.
This is intended to facilitate opening and closing of the fixed contact 100 and the fixed contact 100. The protrusion 128 is provided integrally with the substrate panel 112 in correspondence with the operation section of the operation sheet 114.
