The present invention relates to a mouse which is an input device of a computer, and more particularly, an antenna in a limited size of a mouse body by replacing a wheel and a button for controlling the movement of the cursor with a touch switch so as to sufficiently secure the internal space of the mouse body. The present invention relates to a wireless mouse having a touch switch capable of improving the transmission capability by forming a length of.

In general, the wireless optical mouse emits light emitted from the mouse body to the contact object (mouse pad) of the mouse body and detects the image generated by the mouse to detect the movement of the mouse body and move the cursor of the computer. Clicking the provided button member is a device that can be input by a separate input means separate from the keyboard.

In particular, the wireless optical mouse has a number of advantages such as more accurate detection of motion than the conventional ball mouse, smooth movement of the mouse body, and wireless connection to a computer. The optical mouse recognizes the movement of the mouse body optically, generates the recognized value as an electric signal, and recognizes the cursor position on the monitor by transmitting the generated signal to the computer wirelessly.

1 is an external view showing a typical wireless mouse, Figure 2 is an exploded perspective view showing a typical wireless mouse, as shown, the wireless mouse 10 is a mouse consisting of the upper, lower cases 11, 12 Left and right push buttons 13 and 14 provided on the main body 10a, the upper case 11, and wheel buttons externally exposed to the middle cover 16 extending from the lower case 12 ( 15) and an optical sensor providing a lower substrate 17 and a light source on which the microswitches 13a and 14a, which generate signals when the left and right push buttons 13 and 14 are clicked, are mounted on an upper surface thereof. It consists of an upper substrate 18 on which the IC chip 18a and the electronic components 18b are included, while the upper substrate 18 wirelessly transmits an optically recognized value to a computer to recognize a cursor position. An antenna 19 is provided.

On the other hand, in designing the wireless mouse 10 having the above-described configuration, the antenna 19 for transmitting signals in terms of cost and mechanical arrangement is a separate component and is not placed outside of the mouse body 10a. A pattern is printed on the upper substrate 18 on which an internal pattern circuit is mounted, together with signal lines.

When the antenna 19 printed on the upper substrate 18 is to be used, the pattern length of the antenna 19 should be formed as long as possible, which is required for the frequency used in the wireless optical mouse 10. Freely available frequency range, of which one of the low frequency bands is used (typically 27 MHz). This is because the length of the antenna 19 should be longer as the length of the antenna 19 is inversely proportional to the frequency.

Accordingly, the antenna 19 is patterned along the outermost line of the upper substrate 18 in order to increase the transmission capacity by maximizing the length of the antenna 19 so as to obtain the maximum efficiency from the upper substrate 18. It should be printed.

The internal structure of the conventional wireless mouse 10 is limited to the mouse body 10a because parts such as the wheel button 15 and the support 17a rotatably supporting the same occupy most of the front space of the mouse body 10a. In FIG. 1, the area of the upper substrate 18 is relatively reduced, and the formation length of the antenna to be pattern-printed is also shortened.

Accordingly, in the related art, as a method of improving the transmission capability by lengthening the length of the antenna 19 while maintaining the size of the upper substrate 18 as it is, the antennas are provided on the left and right sides of the top substrate 18. Next, the connecting holes 18c electrically connected to both ends of the terminal 19 were formed through the wires 19a, and one end and the other end of the wires 19a were respectively inserted to extend the pattern length of the antenna 19.

However, the assembly of connecting the wire 19a to the connection hole 18c of the upper substrate 18 in the mouse assembly line is cumbersome, not only has to add a wire assembly process, but also increases the number of components, thereby reducing work productivity. As a result, the cost of manufacturing increased.

In addition, since the operation of changing the position of the cursor up and down by rotating the wheel button 15 is performed by the user rotating the wheel button 15 using a finger, a user who frequently uses the wheel button 15. If you use your finger repeatedly, the fatigue will increase and it will harm your health.

In addition, the mechanical sound generated when the left and right pushbuttons 13 and 14 and the wheel button 15 are pressed and rotated acts as a noise to cause noise pollution that hinders the working environment.

In FIG. 2, reference numeral 19b denotes a feed point connected to a pattern circuit printed on the upper substrate.

Accordingly, the present invention has been made to solve the above problems, the object of which is to increase the area of the upper substrate in the limited internal space of the mouse body to improve the transmission performance of the antenna, while reducing the manufacturing cost by reducing the number of components To improve assembly workability, reduce finger movements of the user and reduce fatigue, while providing a wireless mouse with a touch switch to create a work environment free of noise pollution.
