Multi-directional input device

Abstract

PROBLEM TO BE SOLVED: To provide a multidirectional input device capable of reducing the size thereof, while retaining the needed size of the rotation radius of a final control element. SOLUTION: By installing a slider 5 and a twisted coil spring 6 to an operating body 4 to mount the body 4 to a lower case 2, the wound portion 6a of the twisted coil spring 6 is provided between a supporting portion 4a of the operating body 4 and the final control element 4B thereof, and also movable contacts 5a3, 5b3 and fixed contacts 11, 14 are provided between the supporting portion 4a of the operating body 4 and the final control element 4B thereof. Consequently, the whole size of the multidirectional input device 1 can be reduced, while retaining the needed rotation radius R of the operating body 4. COPYRIGHT: (C)2005,JPO&NCIPI

Description

technical field [0001] The present invention relates to a multi-directional input device mounted on, for example, a mobile phone or a portable audio device, which can be rotated and pushed in, and more particularly to a multi-directional input device that can be miniaturized without degrading operability. . Background technique [0002] Conventionally, in mobile phones, etc., there is known a multi-directional input device in which a rotary switch as a rotary operation type electric component and a tactile switch as a push-in operation type electric component are arranged close to each other, The first electric signal, for example, moves the cursor to sequentially select a desired telephone number from a plurality of telephone numbers displayed on the liquid crystal display part, and according to the second electric signal output from the rotary switch, for example, sets the call mode to the above-mentioned The selected phone number is automatically dialed. [0003] In add...

Problems solved by technology

[0011] For this reason, the overall size H of the input device 101 in the illustrated Y direction needs to be at least the size H1 of the lower half of the winding portion 140a and the size for setting the fixed contacts 110-112 added to the rotation radius R. The size of H2 or more (H≥R+H1+H2), therefore, there is a problem that it is difficult to miniaturize the overall size H of the input device 101
