Keyboard on a kind of mobile phone in being 01246962.9 Chinese patent, application number is disclosed, it mainly by try to get to the heart of a matter, card, push button and conducting contact form, wherein push button is 2-4, the conducting contact of each push button is 4-8, their uniform branches are in inboard week of hole on the card at this push button, a number is represented in a contact, and this number is printed on the card on every side of hole.Button is resilient (can a tilt) column type electric conductor, can be provided with contact salient point around the push button.A push button in this keyboard can be transferred to several numbers (telephone number numeral), and this structure has reduced key number in the keyboard greatly, and further miniaturization is laid a good foundation for mobile phone.But this kind mode also comes with some shortcomings: the one, and the conducting number of contacts of above-mentioned utility model and the combination of push button can't be arranged in pairs or groups easily with ten numerals of 0 to 9 in the mobile phone, make troubles to the user.The 2nd, the conducting contact of above-mentioned utility model is owing to be an inboard week of the hole of uniform branch on card, surpasses four as the conducting contact of a push button, will inevitably strengthen the probability of maloperation.

In addition, in the current digital product, as mobile phone, MP3, digital camera be extensive use of a kind of five dimension navigation keys by the key control input method, the levers pushing structure realization information input by five dimension navigation keys, function selecting etc.What is called five dimensions are exactly that lever pushing key is divided into, down, a left side, the right side and five directions in bottom that push key realize that five kinds are selected input.

Summary of the invention the purpose of this invention is to provide a kind of direction number keyboard, is used to solve the common keyboard problem such as big that is awkward, takes up room.

For achieving the above object, direction number keyboard of the present invention, on key support board, be provided with two five dimension navigation keys, and five dimension navigation keys comprise five key positions at upper and lower, left and right and middle part, the corresponding respectively order input position that numeral 0 to 9 is set, ten key positions of two five dimension navigation keys; Five dimension navigation keys are lever pushing bond structure, and the key face of lever pushing key is that circular configuration or the key face width degree of diameter 8mm to 10mm is the rectangular configuration of 8mm to 10mm; Described lever pushing key bottom is a column structure, and the top of column structure is provided with the key face of pressing key.

After adopting said structure, numeral of each direction indication and each direction all can have a conducting contact to link to each other with the wiring board of main frame.Under the user on time, the conducting contact of button bottom can with the wiring board joint, and on screen, show corresponding digital.

Advantage of the present invention is: simple in structure, be widely used, handsome in appearance, processing ease, can also be by up and downly the controlling of finger, and can save taking up room of numerical key greatly to numerical key, for the user provides comfortable service condition.
