Embodiment Construction

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In addition, the case where the protrusion forming member of the present invention is applied to the movable contact body of a multidirectional input device will be described below. However, the application object of the protrusion forming member of the present invention is not limited to this, and can be appropriately changed. In addition, the so-called multi-directional input device is a device that is used in remote controllers of various electronic equipment, mobile phones, etc., and obtains different signals according to the tilt angle of the operating body.

[0041] Reference figure 1 and figure 2 The overall structure of the multi-directional input device using the protrusion forming member of the present invention will be described. figure 1 It is an overall perspective view of the multi-directional input device according to the embodiment of the present i...

Abstract

Disclosed is a protrusion forming member whereby process man-hours are reduced, production efficiency can be improved, and a large height difference can be easily formed in the protruding portion formed on a board material. Also disclosed is a method for manufacturing the protrusion forming member. A circular board section (22) positioned inside of an annular opening (45) formed on the board material, and a flange section (24) positioned outside of the annular opening (45), said sections being demarcated by the opening (45), and a plurality of arm sections (23), each of which has a length longer than the opening width (L) of the annular opening (45) and connects together the circular board section (22) and the flange section (24), are formed by punching out the board material, and the circular board section (22) is pressed in the direction perpendicular to the flange section (24), thereby forming a predetermined gap between the circular board section (22) and the flange section (24).

Description

Technical field [0001] The present invention relates to a protrusion-forming member and a method of manufacturing a protrusion-forming member that are processed by a press or the like, and more particularly to a method of manufacturing a protrusion-forming member and a protrusion-forming member formed by processing a metal plate material. Background technique [0002] Conventionally, as a method of forming protrusions on a sheet material by a press or the like, a method of forming protrusions on a sheet material by deep drawing processing is known (for example, refer to Patent Document 1). In the conventional deep drawing process, the metal sheet is subjected to multiple deep drawing by a press, so that the metal sheet is not broken and the protruding part slowly protrudes from the metal sheet.
