The present invention relates to an optical pen-type mouse, and more particularly, to an automatic scrolling optical pen-type mouse and an automatic scrolling method that can implement a scrolling or page up-down function simply by moving a pen-type mouse without using a physical scroll switch.

In general, a mouse of a computer is mainly used for executing or controlling an application program, and may be referred to as an input device that is essentially used for most computer systems oriented to the current GUI.

However, such a mouse has a problem in that its precision is lowered when a figure or text is directly produced or devised in a specific application program.

An optical pen-type mouse which solves the disadvantages of the conventional mouse is shown in FIG. 1.

Such a pen shape makes it easy to carry without fatigue even for a long time use, easy to use even in a narrow space, and has more excellent functions such as precise work or handwritten expression.

As is well known, a general optical pen-type mouse includes a light emitting unit which is implemented as an LED and irradiates light, an image sensor which receives light reflected from the reflecting surface and converts the light reflected from the reflecting surface into an electrical signal and outputs the light; Implemented by the light-receiving part implemented by the imaging lens and pressure sensor, etc., it detects and presses the pressure according to the contact with the bottom surface (that is, the reflective surface) (presses the left button on a normal mouse). Double-click on the left button of the mouse) to select and execute the icon, and then click and drag the touch sensor to input a picture or text, and the plane coordinates to move based on the electrical signal received from the light receiver. That is, a microcomputer for calculating (X, Y) coordinates) to be transmitted to the computer main body through a transmitting unit, a scroll switch 4, and the like are provided. Sensor, LED, a pressure sensor or the like is mounted on the main board (2).

The scroll switch 4 is an input switch which is axially coupled so as to be freely rotated so as to protrude outward through a hole formed in the side of the body to perform a scroll function or a page up down function.

However, the optical pen-type mouse according to the prior art as described above has the following problems.

That is, as described above, the optical pen-type mouse according to the related art employs the scroll switch 4 as a means for performing a scroll function or a page up-down function, and the scroll switch 4 takes up a lot of physical space. As a result, the thickness of the pen-type mouse becomes thicker, and as a result, it is difficult for a user to grip naturally as a pen.

The pen-type mouse needs to input a picture or character by holding it naturally like a real pen in order to perform its functions and create demand. The pen-type mouse is satisfied with the user due to the scroll switch 4 which takes up a lot of volume and space. I will not give.

In addition, in order to page up or down the scroll bar as in the prior art, the user must touch the physical scroll switch 4 with a finger to rotate it clockwise or counterclockwise. It caused fatigue to the user and avoided pen-type mice.

The present invention was created to solve the above problems of the prior art, and the object of the automatic scrolling optical pen-type mouse and the automatic scrolling method according to the present invention is to simply move the pen-type mouse up and down even without a physical scroll switch. Scrolling or page up and down can be implemented just by moving, and the scrolling function (or page up / down function) can be implemented without the physical scroll switch, and the volume is minimized, so that it is almost like using a real pen. It can be implemented in size, and by scrolling only by moving the pen-type mouse itself, not the physical switch, the user does not need to perform a finger gesture for implementing scrolling function separately. The touch sensing unit An optical pen-type mouse is provided that is suitable to allow scroll mode to be performed only when in contact.

An automatic scrolling optical pen-type mouse according to the present invention for achieving the above object includes a scroll key input unit for inputting a scroll setting key in an optical pen-type mouse including a light emitting unit, a light receiving unit, a contact detecting unit, a microcomputer and a transmitting unit; And calculating (X, Y) (horizontal and vertical) coordinate values based on the electrical signal received from the light receiving unit, and receiving the (X, Y) coordinate values when receiving a scroll setting key from the scroll key input unit. Characterized in that it comprises a microcomputer 140 to convert the output to the 'scroll up down code'.

Automatic scrolling method in the optical pen-type mouse of the present invention for achieving the above object, the step of receiving an electrical signal from the light receiving unit, calculating (X, Y) coordinate value based on the received electrical signal, scroll setting Determining whether a key has been received; converting a (X, Y) coordinate value into a 'scroll up down code' when receiving a scroll setting key, and transmitting the same to a computer through a transmitter; .

The following will be described in detail with reference to the accompanying drawings, preferred embodiments of the present invention, an automatic scrolling optical pen-type mouse and an automatic scrolling method thereof.

Figure 2 is a block diagram of an automatic scroll optical pen-type mouse according to an embodiment of the present invention.

As shown in FIG. 1, an automatic scrolling optical pen-type mouse according to an embodiment of the present invention includes a light emitting unit 111, a light receiving unit 112, a contact detecting unit 120, a button input unit (not shown), and a transmitting unit ( In the optical pen-type mouse including 150, the microcomputer 140 and the scroll key input unit 130 having new functions and configurations are further included.

The light emitting unit 111, the light receiving unit 112, the contact detecting unit 120, the button input unit (not shown), and the transmitting unit 150 are known to those skilled in the art before the present application. The light source 111 is provided with an LED, and the light receiving unit 112 includes an image sensor to convert an optical signal into an electrical signal and output the electrical signal. The contact detecting unit 120 includes a pressure transmitter and a pressure sensor. It is configured to detect whether the light is reflected on the reflective surface and outputs a detection signal to the microcomputer 140, the button input unit performs a function corresponding to the left and right buttons of the normal mouse.

The scroll key input unit 130 is a user interface for inputting a scroll setting key.

The microcomputer 140 calculates (X, Y) (horizontal and vertical coordinates) coordinate values based on the electrical signal received from the light receiving unit 112 and receives a scroll setting key from the scroll key input unit 130. In this case, the (X, Y) coordinate value is converted into a 'scroll up down code' and outputted.

That is, the microcomputer 140 performs a 'scroll mode' when receiving the scroll setting key from the scroll key input unit 130, and performs a 'cursor movement mode' when not receiving the scroll setting key.

Here, the 'scroll mode' is a mode in which the user can input the scroll setting key through the scroll key input unit 130 to move the coordinates according to the movement of the pen-type mouse as a scroll function or a page up down function in the computer main body.

The cursor movement mode is a mode in which the user does not set the scroll mode through the scroll key input unit 130. The cursor movement mode is a mode in which coordinate movement according to the movement of the pen-type mouse is operated by the cursor movement of the computer main body. to be.

The microcomputer 140 generates a step code based on the coordinates calculated in the normal case, that is, in the cursor movement mode, and transmits the step code to the computer body through the transmitter 150, and the computer body performs an operation of moving the cursor based on the microcomputer 140. do.

3 is a detailed block diagram of the microcomputer of FIG. 2.

As shown in FIG. 3, the microcomputer 140 includes a control unit 141 and a code conversion unit 142.

The control unit 141 calculates (X, Y) coordinate values based on the electrical signal received from the light receiving unit 112 and codes them into (X, Y) step codes (ie, coordinate data codes), and the scroll key. When the scroll setting key is received from the input unit 130, the code conversion unit 142 outputs a code conversion control signal.

When the code conversion unit 142 receives the code conversion control signal from the control unit 141, the code conversion unit 142 converts the (X, Y) coordinate values to the scroll up code under the control of the control unit 141. Convert.

When the Y coordinate value of the received (X, Y) coordinate value is increased (that is, when the pen-type mouse moves upward), the control unit 141 controls to convert to a scroll up code and receives the received ( X, Y) If the Y coordinate value of the coordinate value decreases, control to convert to a scroll down code.

On the other hand, in the automatic scrolling optical pen-type mouse according to another embodiment of the present invention, the control unit 141 to the code conversion unit 142 only when receiving a touch detection signal from the touch detection unit 120 ' Output the code conversion control signal.

In other words, the scroll function is performed only when the scroll setting key is input and the touch detection signal is input.

That is, in the automatic scrolling optical pen-type mouse according to another embodiment of the present invention, even if the user inputs the scroll setting key through the scroll key input unit 130, the contact detecting unit 120 does not detect the contact (that is, When the pen-type mouse does not touch the bottom surface of the reflective surface), the controller 141 does not output a 'code conversion control signal' to the code conversion unit 142, and performs a cursor movement mode which is a normal mode. .

On the other hand, even if the touch detection unit 120 detects a contact and outputs a detection signal to the control unit 141, if the scroll setting key is not input, the scroll function is not performed and the normal click and drag or data input mode is of course. to be.

The following describes the automatic scrolling process by the automatic scrolling optical pen type mouse of the present invention having the above configuration.

4 is a flowchart of an automatic scrolling method in an optical pen-type mouse according to an embodiment of the present invention, and FIG. 5 is a state diagram of use of the optical pen-type mouse according to the embodiment of FIG. 4.

As shown in FIGS. 4 and 5, the automatic scrolling method in the optical pen-type mouse according to an embodiment of the present invention, when an electrical signal is received from the light receiving unit 112 (S410), the control unit 141 is received The (X, Y) coordinate value is calculated based on the received electrical signal (S412).

The controller 141 determines whether the scroll mode is the scroll mode based on whether the scroll setting key is input (S414), and transmits a 'code conversion control signal' to the code conversion unit 142 when the scroll setting key is received.

The code conversion unit 142 that receives the code conversion control signal from the control unit 141 converts the (X, Y) coordinate values into a scroll up code (S416).

The control unit 141 transmits the 'scroll up down code' performed by the code conversion unit 142 to the computer main body through the transmission unit 150 (S418).

Receiving the 'scroll up down code' as described above, the computer main body performs down or down page up (S420).

The microcomputer 140 converts the scroll up code when the Y coordinate value of the calculated (X, Y) coordinate value increases (that is, when the pen-type mouse moves upward) and calculates the calculated (X, Y). When the Y-coordinate value of the coordinate value decreases (that is, when the pen-shaped mouse moves downward), it is converted into a scroll down code and transmitted to the computer main body through the transmission unit 150.

On the other hand, if the control unit 141 does not receive the scroll setting key, it generates a step code based on the calculated coordinates and transmits it to the computer body, and the computer moves the cursor based on this (S450 to S454).

6 is a flowchart illustrating an automatic scrolling method in an optical pen-type mouse according to another embodiment of the present invention, and FIG. 7 is a diagram illustrating a state of use of the optical pen-type mouse according to the embodiment of FIG. 6.

In the automatic scrolling method using the pen-type mouse shown in FIGS. 6 and 7, even if a user inputs a command key by pressing a button of the scroll key input unit, the pen-type mouse does not scroll unless the pen-type mouse contacts the reflective surface. The scroll mode is performed only when the user touches the reflective surface (of course, the user must input a scroll command key).

That is, in the embodiment illustrated in FIGS. 6 and 7, the scroll mode is performed only when the scroll setting key is input and the touch sensing input is performed.

In step S414 of FIG. 4, the control unit 141 that receives the scroll setting key controls the code conversion by outputting a 'code conversion control signal' to the code conversion unit 142 only when the touch detection signal is received.

Receiving a touch detection signal, of course, means that the touch detection unit 120 is in contact with the reflective surface to send a touch detection signal to the control unit 141.

The above embodiments of the present invention are merely one embodiment of the technical idea of the present invention, and of course, other modifications are possible within the technical idea of the present invention.

The automatic scrolling optical pen type mouse and automatic scrolling method of the present invention having the configuration and operation process as described above have the following effects.

First, even without a physical scroll switch, the scroll function or the page up / down function can be realized by simply inputting the scroll setting key (that is, by moving the pen-type mouse up and down using only the coordinate shift value). .

Second, by implementing a scroll function (or page up / down function) without having a physical scroll switch, the pen-type mouse can be implemented in a size close to the feeling of using a real pen by minimizing the volume of a pen-type mouse.

Third, the user does not need to perform finger movements to implement the scrolling function by simply moving the pen-type mouse itself instead of the physical switch. Therefore, the user can provide a very convenient and simple scrolling environment. It can be effective.

Fourth, it is possible to provide an optimal user environment by allowing a user to select a scroll mode and a cursor movement mode.

Fifth, the scroll mode can be performed only when the pen-type mouse touches the floor, thereby providing a better user experience.
