Embodiment Construction

[0056] The above and other advantages of the present invention will become more apparent by describing in detail preferred embodiments with reference to the above-mentioned accompanying drawings.

[0057] refer to figure 1 , which describes the exploded structure diagram of the roller key according to the first embodiment of the present invention. Among them, in order to show the structure of this embodiment more clearly, the rolling ball 1 is separated from the housing 2, but those skilled in the art can understand that in actual use, the rolling ball 1 is placed in the housing 2, and according to It works in the following way. Wherein, the rolling ball 1 is placed in the casing 2, and generally speaking, the diameter of the rolling ball 1 is slightly larger than the diameter of the rolling groove 23 opened on the panel 21 of the casing 2, so that the rolling ball can be placed in the rolling groove 23 so as not to fall off from the ball groove 23. The housing 2 includes a...

Abstract

The invention provides an operational method for the direction key on a mobile terminal as well as relevant roller key; wherein, the key comprises a casing, a main board, a rolling ball and a senor. The sensor comprises four rollers and a plurality of luminous elements and light receiving elements corresponding to each roller respectively; the central axial lines of the four rollers are intersected with each other on the same plane, and a plurality of open parts are evenly arranged on each roller at intervals; the light receiving elements are all connected with a first control circuit, and the light receiving element will generate a pulse signal each time during the period when the light receiving element receives the light transmitted from each luminous element before disappearance. The invention also provides a mobile terminal, which uses the roller key as the direction key. By use of the operational method of the direction key on the mobile terminal, a user can control the cursor on the mobile terminal to slide freely in any directions, such as leftward, rightward, downward and upward. The single click or double click operations can be completed at the same time. The invention has the advantage of enormously facilitating the operations for the users.

Description

technical field [0001] The present invention relates to peripheral devices of devices such as computers and mobile terminals, and in particular relates to a key and a method for using the key. Background technique [0002] At present, since mobile terminals are mainly used for handheld use, generally speaking, these mobile terminals will not be connected with an external mouse or other external devices. Therefore, the direction keys of a mobile terminal are often composed of four keys, which are used for Up, down, left, and right operations, such as most mobile phones are all like this (such as the W810C model product produced by Sony Ericsson Company), or the direction key is composed of two keys, which are used for up (left) and Down (right) operation. Such a mobile terminal is also suitable for common operations, such as writing text, looking through menus, etc., but it seems a bit clumsy in some cases. For example, many mobile terminals are now equipped with Windows CE ...
