Problems solved by technology

But this method of using the length of the pressing time to expand the function of the button cannot meet the needs of more input functions. It is necessary to expand more buttons to increase the function of more input, but the expansion of the buttons will There is a problem of insufficient space and increased costs
[0003] As can be seen from the above, in order to increase the input function of key presses, the length of key press time can be used as two input functions, but it cannot meet the requirements of more input functions; or by increasing the number of keys, it will make the overall manufacturing cost increase
Therefore, in actual use, there are obviously inconveniences and shortcomings, and there is room for improvement.

Embodiment Construction

[0015] The present invention is a method for expanding a single button into multiple functions by using a light signal indication, and the method is mainly applied to a device using the button as a function input. And for the convenience of the following explanation is figure 1 The optical drive 11 shown in is used as an example, but this method is not limited to be applicable to the optical drive 11 only. In the normal situation of the optical drive 11 , that is, before this method is used, the keys 12 of the optical drive 11 are only used to manipulate the control tray 13 . And in order to increase the function of the button 12 in this method, only the control method of the software needs to be changed to achieve it.

[0016] The method adopted by the present invention is to divide the input of each function into three stages of key function input, light signal indication and key confirmation, and cooperate with the light signal display of the indicator light 14 . The pres...

Abstract

The invention discloses a method for extending button key with single function to button key with multiple function through lamp number indicator. The button key as a device for functional input is cooperated with lamp number indicator of at least one indicator light so as to input each function in execution area in mode of divided phases: A press of pushing the button key represents different meanings. The operation includes following steps: (1) multifunctional state is activated by the button, (2) the indicator light displays state of first lamp number, (3) within a holdup time, pushing the button key to select the function in order to execute the function selected in this time. Thus, button key with single function is extended to button key with multiple functions. The invention can obtain more operational functions, and reduce number of button key in a device.

Description

technical field [0001] The present invention relates to a method for using a light signal to indicate that a single button can be expanded into multiple functions, in particular to a device applied to the button as a function input. The method is to divide the pressing of the button into multiple stages, Confirmation of the instructions to expand a single key to have multiple functions. Background technique [0002] In the current device with key input, the key can only provide a single input function, or the length of time the key is pressed can also be used as the function of two inputs. For example, pressing the button for 1 second means executing the first function, and pressing the button for more than 3 seconds means executing the second function. But this method of using the length of the pressing time to expand the function of the button cannot meet the needs of more input functions. It is necessary to expand more buttons to increase the function of more input, but ...
