This application claims priority to Taiwan Application Serial Number 96139281, filed Oct. 19, 2007, which is herein incorporated by reference.
1. Field of Invention
The present invention relates to a control button. More particularly, the present invention relates to a six-direction button
2. Description of Related Art
With rapid technique development, various electric equipments have become very popular in our life. For example, common electric equipments include a television, a video recorder, an audio, a projector, etc. Most of the electric equipments are operated by a remote control. The functions controlled by the remote control have highly increased, and the number of the control buttons of the remote control has also increased. The large number and different kinds of control buttons on the remote control would complicate the operation interface of the remote control, and the user would not easily operate the remote control.
The invention provides a six-direction button. The six-direction button includes a base, a rotation detector having a rotation pin disposed on the base, a button cover coupled with the rotation pin, and four pressure detectors disposed on the base under the button cover. The button cover and the rotation pin may be rotated clockwise or counterclockwise. The pressure detectors are arranged according to an up side, a down side, a left side, and a right side of the button. The cover button cover touches one of the four pressure detectors when the button cover is pressed.
As embodied and broadly described herein, the six-direction button could integrate the wheeling function and the direction function and simplify the space arrangement of the operation interface.
It is to be understood that both the foregoing general description and the following detailed description are by examples, and are intended to provide further explanation of the invention as claimed.
The accompanying drawings are included to provide a further understanding of the invention, and are incorporated in and constitute a part of this specification. The drawings illustrate embodiments of the invention and, together with the description, serve to explain the principles of the invention. In the drawings,
Reference will now be made in detail to the present preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.
Refer to
The six-direction button 100 may have a wheeling function and a direction function. The button cover 130 and the rotation pin 122 con rotate clockwise or counterclockwise, and the six-direction button 100 can be regarded as a wheel button. The button cover 130 further touches one of the pressure detectors 140, 142, 144, 146 when the corresponding side of the button cover 130 is pressed, and the six-direction button 100 may be regarded as a direction button.
The base 110 may be a printed circuit board. The six-direction button 100 may have a processor 150 disposed on the base 110. The signals of the pressure detectors 140, 142, 144, 146 and the rotation detector 120 can be transmitted to the processor 150 and be processed. The processor 150 can be a programmable logic device (PLD), a field programmable gate array (FPGA), a complex programmable logic device (CPLD), or an integrated circuit chip (IC chip). The shape of the button cover 130 may be a circle or a square.
The rotation detector 120 may have a torque spring 124. The torque spring 124 is mounted with the rotation pin 122. The button cover 130 can return to an original position after the button cover 130 is rotated as a wheel. The type of the pressure detector 140, 142, 144, 146 can be a press button. The six-direction button 100 may integrate the wheeling function and the direction function, and would simplify the space arrangement on the operation interface of the remote control.
The six-direction button 100 may be utilized in a remote control, such as a remote control of the document projector. As shown in this embodiment, the press button type of the pressure detector 146 is pressed when the left side of the button cover 130 is pressed. Then the signal generated by the pressure detector 146 is transmitted to the processor 150, and a cursor on the screen is moved leftward till the button cover 130 is released. In one embodiment, the document projector provides a zoom-out function when the button cover 130 and the rotation pin 122 rotate clockwise, and the document projector provides a zoom-in function when the button cover 130 and the rotation pin 122 rotate counterclockwise. In another embodiment, the document projector provides the zoom-in function when the button cover 130 and the rotation pin 122 rotate clockwise, and the document projector provides the zoom-out function when the button cover 130 and the rotation pin 122 rotate counterclockwise.
It will be apparent to those skilled in the art that various modifications and variations can be made to the structure of the present invention without departing from the scope or spirit of the invention. In view of the foregoing, it is intended that the present invention cover modifications and variations of this invention provided they fall within the scope of the following claims and their equivalents.
