The length L of 11.

In another embodiment, please refer to FIG. 1 to FIG. 2 and FIG. 4 together. FIG. 4 is a functional block diagram of a keyboard according to another embodiment of the present invention. The keyboard body 11, the support leg 12, the motion sensor 13, the power source 14, and the processor 15 further have a controller 16. In the embodiment, the processor 15 is configured with setting information. The setting information indicates the preset inclination degree of the operation surface 111, for example, a preset direction angle including the normal line U and the X axis of the operation surface 111, a preset direction angle of the normal line U and the Y axis of the operation surface 111, and the operation surface 111 of the operation surface 111 The preset direction angle of the normal U and Z axis. The controller 16 is configured to provide the user with the angle at which the preset operation surface 111 is tilted, and generate a setting signal to the processor 15 according to the angle of the tilt of the preset operation surface 111, and the processor 15 determines the setting information according to the setting signal, and according to The information and tilt information are set to generate a control signal to the power source 14. As before, since the tilt information used in the embodiment is the tilt angle information, the setting information here may be angle-related setting information. For example, in other embodiments, information such as height may be used, and the setting information may be modified accordingly.

Specifically, the controller 16 provides, for example, a numeric key on the keyboard body 11. The user can input the degree of inclination of the operation surface 111 through the numeric keys. For example, the angle between the operation surface 111 and the horizontal plane is set to 5°. The controller 16 generates a setting signal to the processor 15 according to the degree of inclination of the user input. The processor 15 determines that the preset direction angle of the normal U and the X axis of the operating surface 111 is set when the operating surface 111 is at an angle of 5° with the horizontal plane. For 85°, the preset direction angle of the normal U and the Y axis of the operation surface 111 is set to 90°, and the preset direction angle of the normal U and the Z axis of the operation surface 111 is 5°.

When the processor 15 sets the setting information according to the setting signal, the motion sensor 13 can provide the direction signal to the processor 15 again, so that the processor 15 generates the control signal to the power source 14 according to the setting information and the tilt information. In another embodiment, the processor 15 can also store the tilt information provided by the previous motion sensor 13 and generate a control signal according to the stored tilt information and the setting information when setting the setting information.

In a practical example, when the keyboard 10 is unbalanced, the user operating the keyboard 10 on the operating surface 111 causes the keyboard 10 to shake. In other words, when the keyboard 10 is used, the motion sensor 13 detects a change in the tilt information of the keyboard body 11, for example, the keyboard body 11 is shaken between the first tilt state and the second tilt state. At this time, the motion sensor 13 provides a direction signal to the processor 15, so that the processor 15 obtains the tilt information when the keyboard body 11 is in the first tilt state and the tilt information when the keyboard body 11 is in the second tilt state, and is located first. The tilt signal is generated in the tilt state and in the second tilt state to generate a control signal.

Specifically, when the keyboard 10 is in the first tilt state, the keyboard 10 is balanced without swaying. However, when the user operates the keyboard 10 on the operation surface 111, since the keyboard body 11 or one of the support legs 12 does not abut against the plane provided by the keyboard 10, the keyboard 10 will be shaken when operated by the user, that is, Shaking between the first tilt state and the second tilt state. At this time, when the tilt information when the keyboard body 11 is in the first tilt state is in accordance with the setting information set by the processor 15, the processor 15 generates the information according to the tilt information of the first tilt state and the tilt information of the second tilt state. The control signal is used to control the power source 14 to adjust the length of the support leg 12 protruding from the keyboard body 11, so that the second tilt state of the keyboard body 11 is gradually changed to the first tilt state. In other words, the amplitude of the keyboard body 11 is gradually reduced until the length of the support leg 12 is adjusted so that the keyboard body 11 is no longer shaken.

In another example, when the tilt information of the first tilt state and the second tilt state of the keyboard body 11 does not meet the setting information set by the processor 15, the processor 15 is located in the first tilt state and the second tilt according to the setting information. The tilt information of the state, the generated control signal, to control the power source 14 to adjust the length of the support body 12 according to the control signal to protrude from the length of the keyboard body 11, so that the keyboard body 11 is no longer shaken, and the tilt information of the last tilt state also conforms to the processor. 15 setting information.

In the former example, the keyboard 10 does not shake when the keyboard 10 is not operated by the user, so the motion sensor 13 does not sense the tilt information change of the keyboard body 11. Next, in another example, when the keyboard 10 is moved to another position, and is set to a new plane or there is a foreign object at the bottom of the keyboard 10, that is, the keyboard body 11 is in accordance with the setting information, and the balance is not shaken. The tilt state changes to another new tilt state. For convenience of explanation, the original tilt state of the keyboard body 11 is referred to as a third tilt state change, and the new tilt state is referred to as a fourth tilt state.

When the keyboard body 11 changes from the third tilt state to the fourth tilt state, the motion sensor 13 detects the tilt information change of the keyboard body 11 and generates a direction signal to the processor 15, and the direction signal indicates that the keyboard body 11 is located at the Tilt information for four tilted states. The processor 15 generates a control signal according to the tilt information of the keyboard body 11 in the fourth tilt state, so that the power source 14 adjusts the length of the support leg 12 to protrude from the keyboard body 11 according to the control signal, thereby returning the keyboard body 11 to the third Tilted state. In other words, the tilt information when the keyboard body 11 is in the third tilt state conforms to the setting information. Therefore, when the keyboard body 11 is changed to the fourth tilt state, the processor 15 generates control according to the setting information and the tilt information in the fourth tilt state. The signal causes the keyboard body 11 to return from the fourth tilt state to the third tilt state.

In the foregoing embodiment, when the keyboard body 11 is shaken between the first tilt state and the second tilt state or is changed from the third tilt state to the fourth tilt state, the motion sensor 13 generates a direction signal, and processes The device 15 generates a control signal according to the direction signal, so that the power source 14 adjusts the support leg 12 so that the tilt information of the last state of the keyboard body 11 conforms to the setting information. In one embodiment, the tilt information of the last state of the keyboard body 11 may be within an error range from the setting information.
