INSTRUCTIONS: TECHNICAL FIELD OF THE INVENTION The present invention relates to a handheld electronic device, and more particularly to a handheld device having a dual function button configuration. [Prior Art] With the continuous innovation of battery technology and semiconductor technology, various handheld electronic devices are popular, such as mobile phones, portable multimedia players (pMp), remote control, Mp3 player, personal digital Personal digital assistant, digital camera, portable global positioning system (portablegi〇balp〇siti〇ning system) electronic sub-code (electr〇nic dicti_^) and SideShQw device for Microsoft VISTA operating system, etc. - However, it is extremely complicated and inconvenient for consumers to carry or use a variety of independent handheld devices. Therefore, many handheld devices integrate two independent systems into the body in a two-in-one manner, such as - SideSh〇wt and a remote control. The combination of the device, or the combination of the mobile phone and the -PMP, usually the combination of the two-in-one is performed by the operation of the shared keyboard, that is, some or all of the keys in the keyboard have two kinds of keys. Function (first function and second function): - The numeric keypad on the right side of the standard computer keyboard has the second function. The design can reduce the number of buttons, but when the dual-function button is used, it needs to be frequently (four) another control button (usually labeled as "second power bin using fdFUnction" or "transform" _)) to switch the button function. Therefore, before the second mother operates the button, it is necessary to first check that the button is currently the first or 201001230 second function. If the function needs to be changed, the correct function is executed, and the use is really not =, The button counts as straight = = = the device contains the second system set game machine (video game c〇ns. _;; type 'such as mobile phone and erect operation, the game machine 设 设 == ° The content of the present invention is to provide a kind of == which can sense the handheld device: the square: the empty button is and ==::=: its function The purpose of the present invention is that the hand-held device of the present invention has a housing, a keyboard, and some or all of the buttons have dual functions, and the device has - gravity sensor' to sense the handheld device on the i-axis In the force distribution state, the sensor sends out - the gravity signal controller is determined by the controller to determine the orientation of the handheld device, and the dual function button is switched according to the result - ^ [Embodiment] Please refer to the first figure, which is a schematic diagram of a handheld 201001230 device with a dual function button configuration, the handheld device has a rectangular housing (1) having a panel (1)) 'the panel (1)) setting There is a keyboard, of course, other components, such as a display (112), may be added as needed. In the figure, the handheld device is a mobile phone and a game machine of two people = the body as an example, but not limited thereto, the keyboard (1) has a basic ^ key (0 to 9) and a symbol key (* and #), wherein The 2, 4, 6, 8, 4, and # buttons have the second function for the game console, that is, the 2, 4, 6, and 8 buttons are the direction control buttons, and the * and # buttons are the second launch buttons, wherein the mobile phone design For the upright operation, the game machine is operated horizontally, so one of the buttons is marked with a direction different from the first function. Continuing to refer to the second drawing, which is a circuit block diagram of a preferred embodiment of the present invention, the housing (1) has two independent systems, namely (la) and a second system (lb), the first and the The second system (la, called this, the keyboard) is provided in the housing (1) is provided with a gravity sensor (2), which can sense the distribution change of gravity on the three-dimensional right angle coordinates, the force sensor (2) Electrical connection i __ buckle: painted 丨丨 cry, α, ., human gravity;), gravity sensor (2) will force the right angle to show the gravity signal on the three-axis distribution state to the controller q ' Control H (3) - the output is connected to the keyboard (1) The controller (3) outputs a switching message according to the direction of the gravity sensor (2) (ie, it is upright or horizontal): The key t] U1i actually switches the double-function button to the opposite direction of the embodiment. When the housing (1) is upright, the = button is switched to the digital and symbol key functions, and when the shell Body (1) is the horizontal 4 6 , 8 , * and # buttons automatically switch to the direction control button and launch button of the 201001230 game machine. The upright Si ginseng diagram assumes that the casing of the handheld device (1) is a forward 卩/, and the longitudinal axis is parallel to the three-dimensional right-angled coordinates m == is parallel to the x_z plane, at which point the gravity completely falls on the z-force (due to:\ (that is, the ground), at this time, the weight of -g will be measured on the z-axis = (and the negative value due to the inverse of the ^ axis), that is, as shown in the third a diagram, right Γ When the body (1) is _90 degrees in the x_z plane and is horizontally 7'', the x-axis replaces the position of the original z-axis, and the gravity is transferred to μ ^ & (3), which is the principle to determine the direction of Λ | ο) In addition, the switch button is for the vertical and horizontal use type, if there is \: two, when the state is set, you can also flip the seatpost shaft', the special operation type. Or 5 weeks of the entire controller's discriminant criteria can be explained, =: It is the invention - the specific embodiment of the specific spirit 2: V:::: range 'other use of the invention The special effects (4) are all within the scope of the patent of the present invention.
