The position of the first contact terminal is applied differently. In addition, the pad 900 includes a second contact terminal 722 at a position corresponding to the position of the first contact terminal 721 of the teaching material display unit (eg, a card). Accordingly, when the first contact terminal 721 provided on the teaching material display unit (eg, a card) and the second contact terminal 722 provided on the pad come into contact with each other, an electrical signal is transmitted to the controller 400. It is possible to distinguish the textbook content display unit (eg card). In the drawing, the textbook content display unit 4 (eg, a card, etc.) corresponds to a case where the pad is positioned.

In addition, referring to Figure 5c, the teaching material classification means according to the third embodiment of the present invention is a method using a probe sensor. That is, in the present invention, each teaching material display unit (for example, a card, etc.) that is a sheet is provided with a teaching material ordering unit 731 indicating a teaching order number, and the teaching material ordering unit for each teaching material contents display unit (for example, a card, etc.) Apply differently. In addition, the pad 900 is provided with a textbook sequence recognition unit (not shown) at a position corresponding to the position of the textbook sequence section of the textbook display unit (for example, a card). There is a contact sensor 732, which is given coordinates and works by sensing static electricity of the hand. Accordingly, the teaching material sequence part 731 provided in the teaching material is located above the teaching material recognition part provided in the pad, and then the corresponding teaching material sequence part 731 is pressed by a hand (or a pen). The push signal is output from the contact sensor 732 of the sequence recognition unit, and the push signal is transmitted to the control unit to distinguish the teaching material display unit (for example, a card).

Next, the contact sensor according to an embodiment of the present invention will be described in more detail with reference to FIGS. 6 and 7.

6 is a circuit diagram of a touch sensor according to the technique of the present invention. As shown in the figure, the touch sensor 40 of the present invention includes a reference signal generator 10 for generating an alternating current (AC) signal, which is a reference signal, and one contact pad (PAD1), and a contact pad. A voltage corresponding to the pulse width of the output signal of the contact signal generator 20 and the contact signal generator 20 that generates signals having different pulse widths depending on whether or not the contact object is in contact with the PAD1 is generated. The voltage generator 30 is provided. The voltage generator 30 is configured as a low pass filter to generate a DC voltage corresponding to the pulse width of the output signal of the contact signal generator 20.

The contact signal generator 20 may generate the first signal when the contact object is not in contact with the first signal generator 21 that generates the first signal having the same phase regardless of whether the contact object is in contact. A second signal generator which generates a second signal having the same phase as the first signal of the unit 21 and outputs a second signal having a phase delayed in proportion to the capacitance component of the contact object when the contact object is in contact; And a phase comparison signal generator 23 for generating an output signal having a pulse width corresponding to the phase difference between the first signal and the second signal.

Accordingly, the first signal generator 21 includes a first resistor R11 and a first input buffer B11 connected in series with the reference signal generator 10, and the first signal generator 21 is a reference signal. Located between the second resistor R12 and the second input buffer B12 connected in series with the generator 10, and between the second resistor R12 and the second input buffer B12, through a separate signal line. It has a contact pad PAD1 connected thereto.

The phase comparison signal generator 23 includes an exclusive OR (XOR) XOR1, and the voltage generator 30 includes a third resistor R13 and a capacitor having a structure of a low pass filter. (C1) is provided.

Hereinafter, the operation of the touch sensor of the present invention will be described with reference to the drawings of FIGS. 7A to 7D.

7A is an operation circuit diagram of the contact sensor 40 when the contact object is not in contact, and FIG. 7B is an output signal waveform diagram of the contact sensor 40 when the contact object is not in contact, and FIG. The operation circuit diagram of the contact sensor 40 in the case of contact is shown, and FIG. 7D is the waveform diagram of the output signal of the contact sensor 40 in the case of contact of the contact object.

First, an operation of the touch sensor 40 when the contact object does not contact the contact pad PAD1 will be described with reference to FIGS. 7A and 7B.

As shown in FIG. 7A, since no contact object contacts the contact pad PAD1, the delay component of the second signal generator 22 does not increase. That is, the second signal generator 22 and the first signal generator 21 have the same reference delay component.

The AC signal applied to the first signal generator 21 of FIG. 7A is input to the first input buffer 17 through a reference delay component of the first resistor R11. The first input buffer B11 generates and outputs a first signal having the same phase as that of the input AC signal.

In addition, the AC signal applied to the second signal generator 22 also passes through the reference delay component of the second resistor R12, and then is input to the second input buffer B12, and the second input buffer B12 is input. A second signal having the same phase as that of the AC signal is generated and output.

Accordingly, the first signal and the second signal have the same phase. However, this is an output state in an ideal environment, and more often the first signal and the second signal having a slight phase difference are more often output as shown in Fig. 7B.

The XOR (XOR1) of the phase comparison signal generator 23 receives the first signal and the second signal output from each of the first input buffer B11 and the second input buffer B12, and the voltages of the two signals. The levels are compared, and if the voltage levels are the same, an "L" signal is generated, otherwise, an "H" signal is generated and output.

Accordingly, XOR (XOR1) generates and outputs a signal having a pulse width proportional to the phase difference between the first signal and the second signal.

At this time, since the first signal and the second signal input to XOR (XOR1) have the same or extremely small phase difference, a signal having no or extremely narrow pulse width is generated.

The capacitor C1 of the voltage generator 30 charges the electric charge by the pulse width of the output signal of the XOR (XOR1) transmitted through the resistor R13, so that a very small voltage, that is, a voltage corresponding to the "L" level, is charged. The branch generates an output signal.

On the other hand, the operation of the touch sensor 40 when the contact object contacts the contact pad PAD1 will be described with reference to FIGS. 7C and 7D.

As shown in FIG. 7C, when the contact object contacts the contact pad PAD1, the delay component of the second signal generator 22 is further increased by the capacitance CH of the contact object.

This is because a contact object, such as a human body, has the property and capacity of capacitance (CH) to accumulate a large amount of charge. The first signal generator 21 receives the AC signal that has passed the reference delay component of the first resistor R11 regardless of whether the first input buffer R11 is in contact with the contact object. Generate a first signal having the same phase.

However, as the contact object contacts the second input buffer R12 of the second signal generator 22, an AC signal, that is, an increase of the AC signal passing through the reference delay component of the second resistor R12 and the delay component of the capacitor CH is increased. An AC signal having a phase delayed by the delayed component of the capacitor CH is input, and a second signal having a phase delayed by a predetermined value from the phase of the AC signal is generated.

More specifically, the input AC signal of the second input buffer B12 is used to delay the delayed phase, i.e., time delay, of "1 / (second resistor R12 x contact object CH)" as shown in FIG. 7D. Have Accordingly, the second input buffer R12 generates a second signal having a delayed phase of "1 / (second resistance R12 x contact object CH)" than the AC signal.

XOR (XOR1) receives a first signal having the same phase as the AC signal and a second signal having a delayed phase by "1 / (second resistance R12 x contact object CH)", and thus "1 / A signal having a pulse width equal to "(second resistance R12 x contact object CH)" is generated.

The voltage generator 30 then receives an output signal of XOR (XOR1) having a pulse width corresponding to the phase difference of " 1 / (second resistor R12 × contact object CH) " 2 charge (R12 × contact object (CH)) "to charge the charge to generate an output signal having a voltage corresponding to the" H "level.

As described above, the touch sensor of the present invention uses a principle in which a time delay occurs in an AC signal passing through a delay component increased by the capacitance component CH of the contact object when the contact object contacts the single contact pad PAD1.

Accordingly, the touch sensor of the present invention electrically detects contact and non-contact of a contact object with only one contact pad PAD1 and generates an electrical signal corresponding thereto.

In addition, if necessary, the touch sensor of the present invention may be provided with a plurality of contact pads. At this time, each of the contact pads independently increases the delay component in the delay path. When the contact object contacts a plurality of contact pads, the delay component of the delay path is increased in proportion to the number of contact pads in contact. .

FIG. 8 is a view illustrating a change in the output level of the touch sensor when the contact object is not in contact with the contact sensor of FIG. 7, and when the contact object is not in contact with the contact sensor, section 2. It can be seen that the signal of "L" is generated as shown in section 4 and section 4, and the signal of "H" is generated as shown in section 1 and section 3 when the contact object is in contact with the contact sensor.
