Turn the lock, the unlocking mode is also root ^ The unlocking of the newsletter of the Xunlin descaling storage unit; the emblem, the shooting secret, the touch of the coordinates, the operation signal to the computer system. The password control method for an input device includes the following steps: (a) providing an input device having a male code control power t», the input device including a standard output circuit for outputting a moving coordinate, a button/ The wheel control circuit is configured to generate a corresponding operation signal in response to the button/wheel operation, the plurality of input keys are used to generate an input signal, a storage unit and a microcontroller, wherein the input key can be a digital key, a letter key, or a digital key In combination with the letter key, the microcontroller includes a password matching module and an unlocking module, and (b) when receiving the input signal generated by the input key, " and determining that the input signal is consistent with the predetermined password, the password The comparison module generates an unlock signal; (c) the unlocking module releases the locking of the storage unit so that the external computer system can access the storage unit, and (d) receives the input signal as the movement of the coordinate output circuit output The coordinate or button ^ roller control circuit responds to the button/wheel to generate the corresponding operation signal, receives and transmits the moving coordinate and operation signal to External computer system. Compared with the prior art, the input device and the password control method thereof, the user needs to input the correct password by operating the input key of the input device, and then unlock the storage unit, so that the recovery operation is effective and can be performed. The password is changed, so that the password control function can prevent other people from arbitrarily accessing the storage unit to protect the data in the input device. β1307031 [Embodiment] As shown in the first figure, the input device is implemented in an embodiment. A hardware architecture diagram of its internal data protection. In the present embodiment, the input device employs a mouse for convenience of description, but is not limited thereto, and may be other types of input devices such as a trackball, a stylus, an operating lever, and the like. The mouse 11 includes a connection interface 110, a storage unit lu, a pressure sensor 112, a microcontroller u3, a locking unit 114, a plurality of input keys 115, a standard output circuit 116, and a button/wheel control circuit. 117 and a display 118. The magic connection interface 110 is used to connect the mouse 11 to a computer system, the connection interface ιι〇 can be a USB interface or a PS/2 interface ❶ input key Π 5 can be a digital key, a letter key, or a number A combination of a bit key and a letter key for generating an input signal. The enter key 115 also includes a password setting button for the user to change the password. The coordinate output circuit 116 conceals (4) the mouse's control signal to the microcontroller 113, and the microcontroller 113 transmits the data input by the coordinate output circuit 116 to the computer system 1 by using the connection interface 110. The button/wheel control circuit 117 is used to control the buttons and the scroll wheel in the mouse U and output corresponding operation signals (such as left, middle and right button signals, scroll signals) of the button and the wheel to the microcontroller 113, the microcontroller 113 also uses the connection interface 11 to transmit the operation signal to the computer system 1 . The display 118 can display password related information during the password operation, for example, when the input password is incorrect, the password error information is prompted, and when the password is changed, the new password information is prompted. The storage unit m is used for storing data. The pressure sensor 112 is located at the bottom of the mouse 11. When the mouse u is in a normal placement state (e.g., flat), the pressure sensor 112 can generate a pressure sensing signal due to the pressure; When the ail is in an abnormally placed state (eg, side or reverse), the pressure sensor 112 does not generate a pressure sensing signal because it is not under pressure. The microcontroller 113 immediately scans the pressure sensing signal generated by the pressure sensor 112 to generate a locking signal to the locking unit 114 when the pressure sensing signal is not scanned for a predetermined period of time. The locking unit 114 receives and locks the storage unit ηι according to the locking signal, so that others cannot access the storage unit 1; the data in the L1 reaches the purpose of protecting the data in the storage unit m. The microcontroller 113 further includes a password comparison module 113 and an unlock module 113p. The password comparison module 1130 receives an input signal from the input key 115: when the input signal includes a password setting signal, the user wants to change. When the password is changed, the password is changed to the 1307031 input signal after the password setting signal; when the input signal does not include the password setting signal, it indicates that the currently input signal is a password signal, compared to the input signal and a predetermined password, when the input When the signal is consistent with the predetermined password, an unlock signal is generated to the unlocking module 1131. The unlocking module 1131 releases the lock on the storage unit 111 based on the unlocking signal to resume the access operation to the storage unit. Therefore, the password control function can reduce the risk that the password can be easily cracked and prevent others from arbitrarily accessing the storage unit, thereby achieving the purpose of protecting the data in the input device. As shown in the second figure, it is a flowchart of a password control method for performing unlocking and changing of data lock using the hardware architecture diagram of the first figure in an embodiment. First, the microcontroller 113 receives the input signal generated from the input key 115 (step S20). The microcontroller 113 determines whether the current input signal Φ includes a password setting signal (step sn) corresponding to the password setting key. If the password input signal is not included in the current input signal, it indicates that the input signal is a password signal, and the weight comparison module 1130 determines whether the input signal matches the predetermined password by comparing the input signal with a predetermined password (step S22). . If the input signal matches the predetermined password, the password comparison module 1130 generates an unlock signal to the unlocking module ι 31 (step S23). The unlocking module 1131 unlocks the storage unit 111 according to the unlocking signal (step S24). If the input signal does not match the predetermined password, the password error message is displayed on the display screen 118 (step S25). The password receiving module re-receives the new input signal and returns to step S22 (step S26). If the password input signal is included in the current input signal, the user wants to change the password, and the password comparison module 1130 changes the password to the subsequent input signal of the password setting signal (step S27). In addition, when the input coordinate is the moving coordinate or the button/wheel control circuit 117 outputted by the coordinate output circuit 116 generates a corresponding operation signal in response to the button/wheel operation, the microcontroller n3 receives and transmits the moving coordinate and the operation signal to The external computer system is 1〇. In the above, the above description is only for the preferred embodiment of the present invention, and has been used for a wide range of functions. Any other equivalent changes or modifications that are not made without departing from the spirit of the present invention should be included. Within the scope of the patent application.
