Embodiment Construction

[0044] Embodiments of the present invention will be described below with reference to the drawings. The following description is an example of the implementation form, showing an example applied to a mobile phone, but it can also be applied to other devices. Specifically, it can also be applied to portable information terminals such as PDAs, AV machines, car navigation systems, Input keys for push-button switches used in the input of electronic equipment such as remote controls for various machines. In addition, the common part in each embodiment is denoted by the same code|symbol, and repeated description is abbreviate|omitted.

[0045] The first implementation form ( Figure 1 to Figure 5 )

[0046] figure 1 Shown is a membrane keypad 10 which may also be mounted on the aforementioned portable telephone 1 . The membrane keypad 10 is formed with an input key group 11 and a multi-point input key 12, wherein the multi-point input key 12 adopts the key input device of the pre...

Abstract

The invention relates to a key input device having a favorable handling property that can input at a correct contact point even if a key is pushed at a misoperating point apart from a normal operating point. Guide protrusions are formed on the bottom of a multipoint input key. The guide protrusions are formed at symmetrical positions facing normal oscillating directions. The multipoint input key is thus inductively inclined to normal swaying directions by the guide protrusion even if pushed at a misoperating point apart from normal operating points, whereby the contact point of a printed circuit board can be surely inputted. It can be thus prevented that the contact point adjoining the contact point of the multipoint input key intended to input is inputted together, and that the intended contact point is not inputted, so that the handling property of the multipoint input key is improved.

Description

technical field [0001] The present invention relates to a key input device with an input key for a push button switch, which is used for input of electronic equipment such as a portable information terminal such as a mobile phone or a PDA, an AV machine, a car driving guidance system, and a remote control device of various machines. Background technique [0002] Electronic equipment is equipped with a plurality of input keys for realizing its functions, but recently, with the multifunctionalization of the equipment, there are more and more examples of key input devices equipped with a single input key that can also be used as a plurality of different inputs. [0003] Figure 14 A mobile phone 1 is shown as an example of a device having such a key input device as described above. The mobile phone 1 is provided with an input key group 2 for displaying numerals, symbols, patterns, etc., and an input key 3 in the shape of an ellipse plate with triangular marks on top, bottom, le...
