Input device

Abstract

The invention provides an input device which cannot cause the deformation of a cover body even if the size of a component part is not uniform, and can be reliably resistant to water. The input device (1) is provided with a waterproof structure, and the waterproof structure is provided with an operation component (10) which is disposed at an operation part (1a); a cover body (20) which is vertically disposed at the periphery of the operation component (10); a substrate (40) which is provided with a gas part (50) which carries out input operation through the movement of the operation component (10); and an elastic piece (30) which covers a substrate, is provided with an opening (30a) corresponding to an electrical part, and is clamped between the cover body (20) and the substrate. The cover body (20) is provided with a rib (20a) which abuts against the elastic piece (30), wherein the section of the cover body (20) is roughly convex. The elastic piece (30) is provided with a thin wall (30c) which abuts against the rib (20a), and the back surface of the thin wall (30c) is provided with a space. The thin wall (30c) elastically deforms through the pressing of the rib (20a).

Description

technical field [0001] The present invention relates to an input device having a waterproof structure capable of reliably waterproofing without deforming a cover body. Background technique [0002] As an input device used in portable terminal devices and various devices, it is desired to be able to use it safely even in an outdoor environment. For this reason, portable terminal devices and input devices are provided with structures designed to improve waterproofness so that water and the like do not enter the device from the periphery of the operation portion (for example, Patent Document 1). [0003] Figure 8 and Figure 9 It is a sectional view showing the configuration of the portable terminal device 100 described in Patent Document 1. FIG. exist Figure 9 Among them, the waterproof structure of the peripheral portion of the keypad 101 of the portable terminal device 100 includes: an upper cover body 104 having a rib (corresponding to Japanese: リブ) 105 erected around ...

AI Technical Summary

Problems solved by technology

[0008] However, in the conventional structure, when the thickness of the elastic sheet and the height of the ribs are not uniform, the rebound force from the elastic sheet is stronger than expected, and the defect that the upper cover 104 is deformed may occur.

[0009] Therefore, there is a problem that the operation part cannot be operated due to the deformation of the upper cover body 104 or the tactile feeling of the operation is deteriorated.

On the other hand, if the fastening force with the lower case is weakened in order to avoid the above situation, the elastic deformation of the elastic piece cannot sufficiently ensure the adhesive force, and as a result, there is a problem that water enters through the gap.
