Multi-directional inputting device

Abstract

The present invention provides a multidirection input device preventing dust from entering by blocking the inside of the case by closing a hole on an upper plate. This device is provided with the case 1 having the upper plate 14 provided with a hole 14b, an operating member 8 slidable in a surface direction of the upper plate 14 within the hole 14b, and interlocking member 9 and 11 which are arranged inside 1p the case and output azimuth signals by being moved by the operating member 8. A disc-shaped knob 15 is mounted on the operating member 8 from the outside of the upper plate 14, the passing hole 14b of the upper plate 14 is closed by the surface of the upper plate 14 side of the knob 15, and the inside 1p of the case is blocked.

Description

Contents of the invention [0001] The present invention relates to a multi-directional input device suitable for various inputs used in mobile devices such as mobile phones and video cameras. Background technique [0002] The drawings of conventional multi-directional input devices will be described below. Figure 5 It is a plan view showing the inside of a conventional multidirectional input device. Figure 6 It is a sectional view of main parts of a conventional multidirectional input device. Figure 7 It is a perspective view of the first interlocking member related to the conventional multi-directional input device. [0003] according to Figure 5 ~ Figure 7 , to describe the conventional multi-directional input device, the frame body 51 has: an octagonal bottom wall portion 51a, and a side wall portion 51b composed of a plurality of wall portions vertically erected from the bottom wall portion 51a. Recesses 51e are provided facing each other on the first side wall por...

AI Technical Summary

Problems solved by technology

However, in the conventional multi-directional input device, the upper plate 59 is provided with a through hole 59a that allows the operation part 57 to slide, and the through hole 59a is in an open state to the outside, so there is a problem that dust and foreign objects will Intrusion from the through hole 59a reduces the contact reliability of the contact

And, utilize a knob that is arranged on the operating shaft 58 to carry out slide action and press operation, can occur wrong slide operation when pressing, or vice versa.
