That is, the conventional mouse 10 has a mouse button 10-1, a coordinate sensing unit 10-2 for detecting the movement of the mouse 10, and the pressed state and coordinate sensing unit of the mouse button 10-1. The mouse function unit 10-3 may collectively control the main operations of the mouse, such as transmitting the movement information of the mouse sensed at 10-2 to the computer 20. Since the configuration of such a mouse is already well known and used technology, a detailed description thereof will be omitted.

On the other hand, as the functions of the computer are improved and downsized, theft of the computer frequently occurs, and a computer that is easy to move like a laptop always has the risk of theft. In particular, the loss of a computer that stores important data can cause huge damage that cannot be compared with the cost of the computer itself.

Accordingly, the present invention has been proposed to solve the above-mentioned problem of theft risk, and the object of the present invention is to prevent theft of the computer by outputting an alarm sound when the mouse is separated from the computer or moved by the intruder. have.

In order to achieve the above object, the computer anti-theft mouse according to the present invention can input a password setting key, an ON / OFF key of the burglar alarm function, and a password of a predetermined length. A keypad unit having a numeric key present; A password memory for storing a password input from the keypad; speaker; battery; And operate by the power of the battery, receive a password from the numeric key according to the state of the key for setting the password, and store the password in the password memory, and when the burglar alarm function is on, from the computer to which the mouse is connected.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

3 illustrates an embodiment of the appearance of a mouse according to the present invention, and a key pad part 31, a speaker 33, and a light emitting diode (3) capable of inputting various key signals to the outside of the case of the mouse 10. 32: LED) and the like. At this time, the keypad 31, the speaker 33, the light emitting diode 32 may be provided at any position of the mouse according to the ease of use.

Referring to Figure 4 will be described in detail a preferred embodiment constituting a mouse according to the present invention.

The keypad 31 is a password setting key used when a user sets / changes a password, an ON / OFF key of the burglar alarm function for setting whether to operate the burglar alarm function, And numeric keys (for example, '0' to '9' keys) for inputting a password of a predetermined length (for example, five digits).

Herein, the encryption setting key or the on / off key of the burglar alarm function may be set by using a '*' key and a '#' key or a combination of these keys and a numeric key. For example, pressing the '*' key instructs the password setting, pressing the '#' key turns on the alarm function, and pressing the '*' and '#' keys in turn turns off the burglar alarm function. Could be. Of course, the type or combination of keys is arbitrary and is not limited to these examples.

The cryptographic memory 36 is a component that stores a password entered by the user through the keypad 31 and is preferably implemented as a nonvolatile memory.

The speaker 33 is a component for outputting an alarm sound, and the battery 34 supplies power to components that require power supply for its operation such as the alarm control unit 35 and the encryption memory 36. Component. It is further preferred that such a battery 34 can be charged by the power supplied from the computer 20.

The alarm control unit 35 is preferably implemented using a microprocessor as a key element for managing the burglar alarm function in the mouse according to the present invention.

The alarm control unit 35 receives the password from the numeric key according to the state of the key for setting the password and stores it in the password memory 36, and when the burglar alarm function is on, the computer 20 to which the mouse 10 is connected. Pre-defined alarm sound is output through the speaker 33 depending on whether power supply from the mouse 10 and movement of the mouse 10 have occurred.

Here, whether or not the power is supplied is to determine that the mouse 10 is separated from the computer 20, and whether or not the mouse 10 is moved is to determine whether the mouse 10 has been touched without permission. In addition, it is preferable that the alarm sound is output in a predetermined step. Since another person may touch the mouse 10 by mistake, it is more preferable to increase the intensity of the alarm sound whenever an unauthorized movement of the mouse 10 occurs. It can be carried out.

The operation of the alarm control unit 35 will be described in detail with reference to FIG. 5.

First, when the user presses the key for setting the password using the keypad unit 31 (S51), the alarm control unit 35 receives the password from the numeric keys of the keypad unit 31 (S51-1), and the current password memory. It compares with the password stored in 36 (S51-2). In other words, it checks whether the current user is entitled to set or change the password.

If you purchased your mouse for the first time, it is a good idea to have it stored as an initial password (for example, "00000") and allow your users to change it.

When the comparison results in step S51-2 are the same, a new password is input from the keypad 31 (S51-3), and the contents of the password memory 36 are updated (S51-4).

When the user presses the burglar alarm function on key to turn the burglar alarm function on (S52), the alarm control unit 35 receives a password from the keypad unit 31 (S52-1), and the current password memory 36 The password is compared with the password stored in step S52-2. That is, to check whether the current user is entitled to turn on the theft alarm function.

When the comparison results in step S52-2 are the same, the burglar alarm function is set to the on state (S52-3). This setting may be done by setting a specific flag bit.

However, when the user presses the burglar alarm off key to turn the burglar alarm off (S53), the alarm control unit 35 receives a password from the keypad 31 (S53-1), and the current password memory. It compares with the password stored in 36 (S53-2). That is, to check whether the current user is entitled to turn off the burglar alarm function.

When the comparison results in step S53-2 are the same, the burglar alarm function is set to the off state (S53-3). This setting may be done by clearing certain flag bits.

In addition, the alarm control unit 35 continues to perform the burglar monitoring routine (S54-1), if the burglar alarm function is currently on (S54).

The anti-theft monitoring routine will be described in detail with reference to FIG. 6.

The alarm control unit 35 determines whether the burglar alarm function is in an on state or in an off state, and sets the number of alarms to 0 at the initial time when the burglar alarm function is changed from an off state to an on state (S61). This alarm frequency is for varying the intensity of the alarm sound according to the number of unauthorized intrusions as described above.

Then, when it is determined that the power supply from the computer 20 is cut off (S62), the alarm controller 35 regards the alarm number as the final alarm number and outputs the alarm sound having the strongest level through the speaker 33 ( S67).

In addition, when the coordinates of the mouse 10 received from the mouse function unit 10-3 are moved from the previous coordinates (S63), the alarm sound corresponding to the current alarm frequency is output through the speaker 33. (S64). If the current alarm frequency does not reach the final alarm frequency (S65), the current alarm frequency is increased by 1 (S66).

On the other hand, from the user's point of view, whether the password is normally entered, whether the current theft alarm function is on or off state will be able to use more conveniently.

That is, the mouse 10 according to the present invention further includes a light emitting diode 32 (LED), but the alarm control unit 35 is a predetermined key is input from the keypad unit 31 (for example, the password input standby, all passwords). Termination of the input, etc.) or when the burglar alarm function is on, the light emitting diode 32 may be further turned on.

In addition, when the mouse 10 is an optical mouse, since the optical signal is continuously received, it may be estimated that an abnormality has occurred in the mouse 10 when the optical signal is blocked. Therefore, when the mouse 10 is an optical mouse, the alarm control unit 35 outputs a predetermined alarm sound through the speaker 33 by judging it as a stolen state when the burglar alarm function is on and the reception of the optical signal is blocked. It is preferable to configure to further include.

According to the present invention, it is possible to easily and accurately grasp the change in the state of computer preservation and to alert, thereby effectively preventing the theft of the computer. Especially in places where a large number of unspecified people are gathered, such as libraries, theft can be prevented more effectively.
