Description

Mouse {Mouse}

The present invention relates to a mouse, and more particularly to a mouse with improved button structure.

A mouse is a peripheral device used in a computer. The mouse is a device developed to freely use a cursor by clicking a button. The mouse is provided with a plurality of buttons and optionally a wheel, which is used by pressing them with a finger.

However, when the finger is used for a long time for clicking the button, it causes a problem such as giving a fatigue to the body such as a finger, a wrist, an arm, a shoulder, and easily causing fatigue or, in severe cases, causing a disease.

In order to improve such a problem, Korean Patent Laid-Open Publication No. 2003-87688 discloses a contact click type mouse configured to generate a click signal when a finger is dropped from a finger contact portion.

This prior art is configured to generate a signal by simply touching or dropping a finger on a contact. Therefore, there is an advantage in that the user does not press a button and uses a mouse without any effort.

However, this prior art generates a signal in the opposite operation, that is, the user's hands off the mouse, rather than the user-friendly operation, there is a problem that it takes a lot of time to adapt to this mouse. In addition, in the drag operation of the mouse, it is necessary to hold the finger continuously, thus giving the user an excessive force to make the user feel tired easily, and there is a possibility of causing a disease. In addition, when the user moves the cursor using the mouse, there is a problem that the risk of malfunction always exists because the sensor must be covered by the finger.

Meanwhile, Korean Patent Laid-Open Publication No. 2000-35033 discloses a touch mouse that generates a click signal by finger contact. In this prior art, since the signal is generated in the same way as the conventional button method, the user can easily adapt and use it.

However, this prior art has a problem that since the button is simply composed of a touch sensor, the user must continue to focus the nerve so that the finger does not touch the sensor unnecessarily in order to prevent a malfunction during the use of the mouse. In addition, there is a big problem that the mouse cannot be used when direct contact between the body and the sensor is impossible, such as when the user hurts his hand and protects it with a foreign substance.

The present invention was devised to solve the above problems, and to provide the present invention to improve the button structure of the mouse to provide a user with ease of use.

Next, the sensing unit 11 positioned adjacent to the button unit 14 includes the left and right sensing units 111 and 113 in the same manner as the left and right buttons 141 and 143 of the button unit 14. do. Optionally, the sensing unit 11 may be formed along only one of the left and right buttons 141 and 143. The sensing unit 11 electrically generates the same click signal as the signal output from the adjacent button unit 14, which will be described later in detail.

In addition, the position of the sensing unit 11 and the button unit 14 is preferably arranged to provide convenience for use of the mouse. That is, when the user grips the mouse, it should be placed where it can be reached directly with less finger movement.

In view of this, in the present embodiment, when the user grips the mouse, the button portion 14 is disposed in front of the case 19 where the finger is located, and along the longitudinal direction in which the button portion 14 is disposed. The sensing unit 11 is disposed on the side. In this case, the sensing unit 11 is formed by extending from the case along the button unit 14, the case by the support member (11a) to position the sensing unit 11 in parallel with the button unit 14 It is fixed at 19.

Therefore, since the sensing unit 11 is provided immediately adjacent to the button unit 14, the user can use the mouse by pressing the button unit 14 or lightly touching the sensing unit 11 where the finger naturally stays. It becomes possible. As another example, the sensing units 113 and 111 may be disposed in front of the button unit 14 as shown in FIG. 2.

On the other hand, the sensing unit 13 detects a change in a signal by physical contact and generates it as a click signal, and the contact surface is fixed to come out of the case 19.

A preferred embodiment of the mouse of the present invention configured as described above will be described with reference to FIGS. 4 and 5. 4 and 5 are circuit diagrams of a mouse according to an embodiment of the present invention.

Referring to the figure, the sensor S is connected to the input terminal of the OP amplifier A, and the capacitor C1 is connected in parallel therebetween. Further, another input terminal of the OP amplifier A is biased with the reference voltage Vcc. Therefore, when a change in the capacitance of the capacitor C1 occurs due to physical contact, the signal is compared with the reference voltage and an input is generated to the OP amplifier A for a signal higher than this (see Fig. 6). In FIG. 6, the area indicated by the hatched line is a signal sensed.

The output terminal of the OP amplifier A is connected to the emitter of the transistor Tr. The base of the transistor Tr is biased with a reference voltage Vcc, and a load resistor R3 is connected to the output terminal of the collector to determine the level of the signal output from the transistor Tr. FIG. 7 illustrates a waveform in which the sensed signal is output through the transistor Tr as shown in FIG. 6. That is, the signal input through the sensor S is output as a signal of a predetermined level (for example, a high signal of + 5V) while passing through the transistor Tr.

The collector of the transistor Tr is connected to an input terminal of a flip-flop logic operator L, such as RS-FF.

On the other hand, the push button (B) is connected to another input terminal of the logic calculator (L), and the capacitor (C2) is connected in parallel therebetween, the click signal in response to the change in the capacitance of the capacitor (C2) Is generated and input to the input terminal of the logical operator L.

Accordingly, the logic operator L processes the signal and outputs the signal to the signal processor 17 as shown in the truth table below.

[Truth table]

input Print R S O1 O2 0 0 Keep all signals Keep all signals 0 One 0 One One 0 One 0 One One - -

When a signal is input through any one of the sensor S or the push button B, the logic calculator L calculates the signal and outputs signals of '1' and '0' as output values O1, The signal is output to the signal processor 17 via O2). On the other hand, if a click signal is input from the sensor S and the push button B at the same time, it does not respond.

On the other hand, as described above, the signal processing unit 17 receives the signals '1' and '0' from the logic operator L, and adds them to the computer as a click signal.

Therefore, the mouse of the present embodiment selectively operates with respect to the signal input of the sensor S and the button B, thereby enabling stable signal processing without malfunction. In addition, since the user can use the mouse as a button or a sensor without fear of malfunction, it is possible to increase the work efficiency while conveniently using the mouse.

Meanwhile, the circuit configuration of FIG. 6 is the same as that of FIG. 4, but switching the click signal input from the push button B and the sensor S using the switch S / W without using the logic calculator L. FIG. It is configured to Thus, the mouse according to this embodiment is configured such that only one of the buttons or the sensor is operated alternatively.
