In addition, the first sensing means is a capacitive sensor for sensing the capacitance changes by the contact of the user finger, the second sensing means is a mechanical switch that is operated by the pressing of the user finger. .

On the other hand, the mechanical switch is characterized in that the dome switch having at least two contacts and the connection between the contact is interrupted by the pressing.

In addition, the capacitance sensing terminal of the capacitive sensor and the contact point of the mechanical switch are simultaneously arranged in each of the plurality of contact regions in the PCB layer.

In addition, the plurality of input processing apparatuses according to the present invention include a user contact portion having a plurality of contact regions and a capacitance or a contact time changed by a user's contact with at least one contact region among the plurality of contact regions. And a capacitive sensor that outputs a first output value when the first threshold amount is reached and outputs a second output value when the second threshold amount is reached.

Here, the first threshold amount represents a touch of the user's finger, and the second threshold amount represents a press by the user's finger.

According to the present invention as described above, in the electronic device capable of user input in the form of a touch pad, a plurality of inputs are possible even with a single touch operation on one contact area, thereby simplifying user input.

In addition, even when security is required, such as input of a password, secure input is possible.

The present invention as described above will be described below with reference to the drawings.

First, a plurality of input processing apparatuses according to an exemplary embodiment of the present invention include a user contact unit 100, a touch sensing unit 200, and a signal processing unit 300 as illustrated in FIG. 1.

The user contact portion 100 is generally made of a flat panel, and the contact area 111 at which the user is in contact with the finger is displayed on the surface by printing or the like. In addition, the user contact portion 100 has a slight elasticity to allow a slight deformation and restoration when the user presses with a finger.

The touch detection unit 200 is disposed to overlap the user contact unit 100 and detects contact of the user's finger at each position corresponding to the plurality of contact areas in the overlapping state, and outputs a predetermined signal 210. ) Includes a PCB substrate 219 disposed thereon.

The signal processing unit 300 detects whether the user's finger touches or approaches the user contact unit 100 and receives a signal output from the sensing unit correspondingly, and converts the signal into a signal form that can be used later by a microprocessor. To print.

At this time, the sensing means 210 of the touch sensing unit 200 measures a pressure or a contact time generated when the user's finger touches or presses the user's finger, and the measurement result is based on at least one reference value. It is determined in which region of the first threshold region and the second threshold region. In addition, a signal having a different value corresponding to each area is output. Thereafter, the signal processor 300 converts each signal to have a digital or analog signal type used by a microprocessor of the electronic device using the output values of the plurality of input processing apparatuses of the present invention.

This operation makes it possible to accept a plurality of inputs for one contact area.

Meanwhile, the sensing means of the plurality of input processing apparatuses according to an embodiment of the present invention includes first sensing means for sensing a first threshold value and second sensing means for sensing a second threshold value. The first sensing means uses a capacitive sensing sensor for sensing the contact pressure corresponding to the first threshold region, and the second sensing means senses the contact pressure corresponding to the second threshold region. Use a mechanical switch for

In such a configuration, when the user touches the contact region 111 at a level corresponding to the first threshold region, the touch signal is output as a signal corresponding to the first threshold region. On the other hand, when the user presses the contact region 111 with the contact pressure of the level corresponding to the second threshold region, not only the contact signal is output from the first sensing means but also the mechanical switch is pressed, thereby causing the second A push signal, which is a signal corresponding to the threshold region, is also output at the same time. When the touch signal and the push signal are simultaneously output, the signal processor 300 determines that the user wants to input a press corresponding to the second threshold region and outputs a push signal.

Next, with reference to FIG. 2, the structure of the multiple input processing apparatus which concerns on one Embodiment of this invention is demonstrated in detail. Referring to FIG. 2, the plurality of input processing apparatuses show a dome 121 constituting the user contact part 100, a silicon layer 120, and a PCB layer 210 constituting the touch sensing part 200. The signal processor 300 is omitted.

First, the PCB layer 210 is disposed with electrodes and circuit elements for forming a sensing means for sensing a touch of a user finger, and becomes the lowest layer of the plurality of input processing apparatuses. In one embodiment of the present invention, the first sensing means for detecting the touch of the user's finger using the at least one electrode to detect the change in capacitance caused by the approach or contact of the human body and output a touch signal Mechanical switch that uses a capacitive sensor and outputs a push signal by intermittent intermittent contact or separation of at least two contacts arranged by the user's pressing as second sensing means for detecting the user's pressing Use

These capacitive sensing sensors and mechanical switches are simultaneously placed in the same contact area. To this end, at a position corresponding to each of the contact regions 111 on the surface of the PCB layer 210, for performing a mechanical switching operation and the pattern of the capacitance sensing electrode 211, which is an electrode for sensing the capacitance The pattern of the switching contacts 215 is formed at the same time. And the mechanical switch structure and the structure for sensing the touch of the user's finger on these patterns are disposed at the same time, the present invention is established.

Each of the contacts 215 and the electrodes 211 has a switching circuit 216 and a capacitance sensing circuit 212 for outputting the contacts sensed by the contacts 215 and the electrodes 211 as electrical signals. Is placed. The output of these circuits is then output via the signal processor 300.

Referring to FIG. 2, two switching contact patterns 215 are formed side by side in each contact region 111 of the PCB layer 210, and a capacitive sensing electrode adjacent to the contact 215 is formed. It can be seen that the pattern of 211) was formed. On the other hand, the shape of the pattern for forming each contact 215 and the electrode 211 at the same time is not limited thereto.

Next, the dome 121 has a plurality of contact regions 111, which are portions of the uppermost layer of the plurality of input processing apparatuses, which are touched by the user with a finger, and at least the contact regions 111 on the surface of the dome 121 are in contact with each other. Numerals, letters or symbols to be input are displayed by printing or the like.

On the other hand, at least the contact area 111 in the dome 121 is made of a material that can pass the electromagnetic energy of the human body to detect a change in capacitance by the human body. General plastic film and the like can be transmitted to the energy of the human body. However, due to such a transmission characteristic, when a finger touches or approaches any one of the contact areas 111, the contact area 111 of a part other than this contact area (a part not desired to be inputted by the contact) can be used. Changes can be detected at the same time. Therefore, in the case of using an energy permeable plastic film, it is preferable to apply a material having an effect of blocking human energy to portions other than the contact region 111.

The silicon layer 120 is formed with a dome 121 in which contact protrusions 122 are formed to intercept the switching contacts 215 formed on the PCB layer 210. When the dome 121 is pressed from the outside, the contact protrusion 122 is lowered to contact the two switching contacts 215 at the same time. When the dome is released, the dome 121 is restored to the original dome shape by the elasticity of the silicon material. 122) rises. Meanwhile, a conductive material is applied to a portion of the contact protrusion 122 that comes into contact with the switching contact to enable electrical connection between the switching contacts 215.

3 is a side cross-sectional view of a form in which the protective layer, the silicon layer, and the PCB layer shown in FIG. 2 are combined. Referring to FIG. 3, a structure in which the silicon layer 120 is contacted and disposed under the dome 121 and the PCB layer 210 is also in contact with the silicon layer 120 can be seen.

Here, the contact protrusions 122 facing downward are formed in the dome 121 of the silicon layer 120, and the two switching contacts 215 are formed on the PCB layer 210, which is the lower side of the contact protrusion 122. This is arranged. In addition, the capacitive sensing electrodes 211 are disposed on both sides of the switching contact 215. In addition, at least the outer side of the dome 121, the support portion 123 for maintaining a constant distance between the PCB layer 210 and the dome 121 is formed.

In this structure, when the user only touches the finger to the contact region 111 of the dome 121, the capacitance sensing electrode 211 detects a change in capacitance, and the capacitance sensing circuit 212 contacts the touch. Will output a signal. In addition, when the user touches the finger to the contact area 111 and then presses the pressure further, the contact protrusion 122 is pressed by the dome 121 and the dome 121 of the silicon layer 120. 215 and the switching contacts 215 are connected to each other to output the push signal from the switching circuit 216.

That is, when the user's finger makes contact only, the touch signal is output only by the capacitance sensing circuit 212. However, when the user presses the dome switch after the contact, the touch signal is output by the switching circuit 216 as well as the touch signal. Done. When only the touch signal is input, the signal processor 300 outputs a signal corresponding to the touch. When the touch signal and the push signal are simultaneously input, the signal processor 300 outputs a signal corresponding to the push.

As a result, the multi-input processing apparatus according to the embodiment of the present invention performs the first signal processing corresponding to the contact when the user makes only a finger touch with respect to the contact area 111. When the user presses with a finger, the second signal processing corresponding to the pressing is performed.

Next, another embodiment of the shape of the touch sensing unit 200 will be described with reference to FIG. 4. In this embodiment, the shape of the switching contact 215 and the capacitive sensing electrode 211 are further improved. That is, referring to FIG. 4, at least one of the two switching contacts 215 serves as the capacitive sensing electrode 211. According to such a structure, since the separate capacitance sensing electrode 211 does not need to be formed, the manufacturing and design can be simplified, and the manufacturing cost can be reduced.

On the other hand, the plurality of input processing apparatus according to another embodiment of the present invention, provided with only a capacitance detection sensor for detecting a change in capacitance caused by the contact of the user's finger, different from the contact and pressing pressure according to the present invention Enable signal processing. That is, the amount of change in capacitance when the finger touches the contact area 111 and the amount of change in capacitance when the finger presses are set as the first threshold area and the second threshold area, respectively. When the change corresponds to each region, the first output value and the second output value may be configured to be output separately.

That is, referring to FIG. 5, the relationship between the pressure at which the user's finger contacts the contact area and the magnitude of the measured capacitance may be confirmed. In other words, the capacitance between the finger and the capacitive sensing electrode 211 decreases with the pressure of the finger. At this time, the magnitude of the capacitance is divided based on the first threshold value and the second threshold value, and when the capacitance is measured by the value of each area, different signals are output.

That is, when the user touches and releases the contact area with his or her finger, if the minimum value of the measured capacitance is greater than the first threshold, the touch signal is output. If the user is smaller than the second threshold, the push signal is output. You can output it. Of course, the threshold which is a reference may be one or plural.

This configuration eliminates the need for disposing a separate mechanical switch, thereby facilitating the design and reducing the manufacturing cost.

According to another embodiment of the present invention, as shown in FIG. 6, when the user performs an input by touching or pressing, the multiple input processing apparatus includes an input display means 400 for indicating completion of each input. It may further include.

By such an input display means 400, when the user makes an input by merely touching the contact point 210, the user generates a first sound or generates a first vibration, and the user presses the contact point 210. When the input is performed, the second sound or the second vibration is generated.

According to such a structure, a user can distinguish and confirm the input which he / she performed correctly, and it becomes possible to perform input operation more conveniently.

Next, a method of using a plurality of input processing apparatuses according to an embodiment of the present invention will be described. Here, an example of what is applied to the password input device of the digital door lock is described.

The multiple input processing apparatus according to the present invention applied to the digital door lock is capable of modifying the standard of the password by the fact that a plurality of inputs are possible in one contact area. That is, a general password consists of simple symbols such as "1, 2, 3, 4" consisting only of numbers or symbols displayed on the touch pad or keypad. However, according to the present invention, at least two input methods of touch and pressing may be applied to each symbol, and at least one of the symbols constituting the password may be applied. That is, the password can be configured as "1 by touch input", "2 by press input", "3 by touch input", and "4 by press input".

In addition, the user can perform user authentication by precisely manipulating touch and press on each symbol when inputting the password of the digital door lock.

According to the password configured as described above, even when numbers or symbols constituting the password are exposed to the surroundings, whether the input operation is touched or pressed is not easily exposed, so the password is input using the touch pad. The security of the device can be improved.
