Embodiment Construction

[0014] Here, the key body 1 is a part that is in direct contact with fingers; the bottom button 3 and the contact switch 7 are all on the base 8, and the upper end of the shell of the bottom button 3 has a through hole through which the contact switch 7 can pass.

[0015] The working principle of the multifunctional composite sliding key device is:

[0016] In the space formed by Cartesian coordinates XYZ, when the button is placed on the XY plane,

[0017] i) The key body 1 can slide along the guide rail 2 in both positive and negative directions on the X axis. When the key body 1 slides to a certain position, the contact point 6 at the bottom of the key body can trigger one of the contact switches 7 on the base 8. Here, It is defined as the X-axis trigger position. The number of X-axis trigger positions is the number of contact switches 7 . The key body 1 is connected with the recovery spring, and the key body 1 returns to the middle of the X-axis under the traction of the...

Abstract

The present invention relates to an input and control device, in particular, it relates to an input and control device with letter keyboard, digital keyboard, mouse or navigation key function. Said input and control device includes guideway, key body, restore spring, two contact push-buttons (switches) positioned at two sides of the key body respectively, one contact push-button (switch) positioned under the key body, one contact point of bottom of the key body and several contact switches on the upper end of the base. Said device can utilize the slide of the key body along the guideway and the combination of all the switches to implement input and control function. Said invention can be applicable to various equipments of handset, PDA and palmtop.

Description

technical field [0001] The invention relates to an input and control device, in particular to an input and control device with the functions of a letter keyboard, a number keyboard, a mouse or a navigation key. Background technique [0002] In the small-sized (pocket) equipments such as existing mobile phone, palmtop computer, PDA, electronic dictionary, general number, letter input device have following several kinds: [0003] 1) In an ordinary mobile phone, the number input is generally realized by ten independent buttons, and the letter input is realized by ten number buttons, and each button represents several different letters respectively. This method cannot directly input letters, and it is not easy enough when performing operations such as text input. [0004] 2) Use a stylus to touch the corresponding letter or number input on the touch screen in a handheld computer, PDA, or electronic dictionary. This method is not convenient for one-handed operation [0005] 3) ...
