First, referring to FIG. 1, the remote controller main body 1 has a plurality of function keys 2 arranged and mounted, and the joystick is located at a position where the user can easily operate the remote controller main body 1 in a state where the remote controller main body 1 is mounted. (3) is mounted. Then, below the joystick 3, a printed circuit board 4 for detecting the operation direction of the joystick 3 is mounted.

In addition, the joystick 3 described above, as shown in Figure 2, the predetermined shape of the projection (5) formed at the bottom and the upper end of the joystick (3) so that the user can easily attach and operate the joystick (3) A substantially half arc-shaped contact portion formed between the projection 5 and the operation knob 6 so that the contact portion of the printed circuit board 4 can be varied according to the operation knob 6 formed on the control knob and the operation amount of the joystick 3. It includes (7). Then, from the lower end of the contact portion 7, that is, from the portion where the protrusion 5 and the contact portion 7 abut to the end of the half arc shape, the thin film conductors 8a and 8c move the joystick 3 in the operation directions (up, down, left). It is attached long in four directions.

Here, the joystick (3) allows the user to easily perform the displacement operation, to be automatically restored to the initial state after operating the joystick (3), when the user manipulates the joystick (3) the contact portion ( In order to maximize the contact efficiency of the thin film conductors (8a, 8c) and the printed circuit board (4) attached to the lower side of 7) was composed of a rubber material with elasticity.

On the other hand, at the upper end of the printed circuit board 4, that is, the portion that is in contact with the contact portion 7 of the joystick 3, as shown in FIG. 3A, a plurality of layers of conductive having a substantially circular shape and divided into four regions. The thin films 9, 9a, 9b. 9c are printed on the printed circuit board 4, and each layer is formed at the center of each region of the printed conductive thin films 9, 9a, 9b, 9c. Connected by 10a, 10b, 10c).

In addition, as shown in FIG. 3B, the rear surface of the printed circuit board 4 includes a microcomputer (not shown) located at the outermost conductive thin film of each of the conductive thin films 9, 9a, 9b, and 9c. Connection terminals 11, 11a, 11b and 11c for connecting are formed. In addition, at the innermost periphery of the conductive thin films 9, 9a, 9b, and 9c, an undivided conductive thin film 12 is printed in a circular shape, and the conductive thin film 12 has a main power supply terminal 13 to supply the main power. )

Here, the thin film conductors 8a and 8c have low resistance values of about 50 ohms or less, and the total resistances of the resistors 10, 10a, 10b, and 10c connected to the conductive thin films 9, 9a, 9b, and 9c. The value has a high resistance value of up to 50 kilo ohms.

On the other hand, Figure 4 is a schematic internal block diagram of a joystick integrated remote controller according to the present invention.

As shown in FIG. 4, the above-described connection terminals 11, 11a, 11b, 11c and the main power supply terminal 13 are respectively connected to the microcomputer 14 and the main power supply Vcc, respectively. A plurality of capacitors C1 to C4 corresponding to the connection terminals 11, 11a, 11b and 11c are connected in parallel between the (11, 11a, 11b, 11c) and the microcomputer 14. In addition, the microcomputer 14 is equipped with a crystal oscillator 15 to generate a pulse signal having an oscillation frequency of 32 kHz, and finally generates control data to be transmitted by using the pulse signal. In addition, an infrared light emitting diode (IR LED) 16 is connected to the microcomputer 14, and the infrared control signal is applied to the target device to repeatedly control the flashing operation at a predetermined period by a control data pulse supplied from the microcomputer 14. Will print In addition, it is the same as the internal structure of a normal remote controller except the above-mentioned structure.

The operation of the joystick integrated remote controller according to an embodiment of the present invention having the configuration as described above is as follows.

When the user operates the joystick 3 mounted on the joystick integrated remote controller by a predetermined displacement, the thin film conductors 8a, 8c of the joystick 3 are printed on the printed circuit board 4, the conductive thin films 12, 9, 9a. , 9b, or 9c) from the innermost circumference to a predetermined range corresponding to the operation amount of the joystick 3.

Accordingly, the driving voltage Vcc supplied from the main power source is supplied to the conductive thin film 12 through the main power connection terminal 13, and then the conductive thin film of the thin film conductors 8a and 8c and the printed circuit board 4 is supplied. The driving current flows through the thin film conductors 8a and 8c having low resistance to the point where the contact point (any one of 9, 9a, 9b and 9c) contacts, and after the contact point described above, the conductive thin film 9 having high resistance value The driving current flows through any one of 9a, 9b, and 9c). That is, when the user manipulates the joystick 3 a lot, the total resistance value of the joystick 3 as a whole has a low resistance value, and when the joystick 3 is operated less, the total resistance value has a high resistance value. Therefore, the amount of current flowing through the microcomputer 14 changes differently according to the operation amount of the joystick 3, and this current is supplied to the capacitors C1 to C4. Here, the resistors 10, 10a, 10b, and 10c and the capacitors C1 to C4 by the joystick 3 have a configuration of RC time constant circuits, so that the microcomputer 14 is shown in FIGS. 5A and 5B. The pulse waveform as shown is input.

Here, when the microcomputer 14 sets the voltage threshold value (threshold voltage value) for recognizing the logic 'low' state and the logic 'high' state to a driving voltage value (0.7 Vcc) of 0.7 times, According to the amount of manipulation of the joystick 3 operated by the controller, the time of conversion of the logic state (logic 'high' or 'low' state) is different from each other. For example, when the operation amount of the joystick 3 is small, as shown in FIG. 5A, the time for which the pulse waveform input to the microcomputer 14 reaches the voltage boundary value (0.7 Vcc) is long, and the operation amount of the joystick 3 is long. In many cases, as shown in FIG. 5B, the time for the pulse waveform input to the microcomputer 14 to reach the voltage boundary value (0.7 Vcc) is shortened.

The microcomputer 14 uses a pulse oscillated from the crystal oscillator 15 to generate a pseudo pulse corresponding to the timing at which the pulse waveform input from the logic 'low' state to the logic 'high' state (see FIGS. 5C and 5D). ), The duty value of the pseudo pulse is calculated, binary control data corresponding to the calculated duty value is generated, and the generated control data is converted into a predetermined pulse signal to convert the infrared light emitting diode ( 16) to transmit. Accordingly, the infrared light emitting diode 16 transmits the infrared signal to the target device to be controlled by using the applied predetermined pulse signal.

Here, the binarization control data according to the operation state of the joystick integrated remote controller is shown in Figs. 6 to 8, in particular, the duty value of the pseudo pulse and the corresponding binarization control data are well shown in Figs. have.

FIG. 6 shows a state in which various control data corresponding to the function key are allocated when the various function keys mounted on the joystick integrated remote controller are operated.

In addition, in FIG. 7, when the operation direction of the joystick 3 is in the positive (+) direction, for example, when the point displayed on the screen of the target device is to be moved upward or leftward, the microcomputer 14 is moved from the microcomputer 14. The binarization control data corresponding to the generated pseudo pulses is shown.

In addition, in Fig. 8, when the operation direction of the joystick 3 is negative (-) direction, for example, when the point displayed on the screen of the target device is to be moved downward or rightward, The binarization control data corresponding to the generated pseudo pulses is shown.

Meanwhile, the control data format transmitted from the infrared light emitting diode 16 is as shown in FIGS. 9 and 10.

First, the pulse waveforms shown in FIGS. 9A to 9D show the control data and the pulse signal transmitted through the infrared light emitting diode 16 when various function keys of the joystick integrated remote controller are operated.

)가 순차적으로 출력된다.As shown in FIG. 8A, as the user operates various function keys, the microcomputer 14 generates a predetermined pulse signal corresponding to the corresponding binarization control data according to the classification of the binarization control data as shown in FIG. Occurs. This pulse signal is repeatedly output at a total of 108 milliseconds. Further, when subdividing the pulse signal, as shown in FIG. 9B, a pair of 9 milliseconds leader indicating that the pulse signal is transmitted and a pair of 8 bits each representing a unique code of the manufacturer who manufactures the product Unique data (Custom), 8-bit control data (Data) for controlling the target device, and 8-bit inversion control data (inverting the control data (Data)

) Are output sequentially.

Here, the leader sent for 9 milliseconds represents a logic 'high' state for 4.5 milliseconds and a logic 'low' state for 4.5 milliseconds. In the unique data, when the binarization control data is '1', the logic 'high' state is continuously generated for 0.56 milliseconds and the logic 'low' state for 1.69 milliseconds, and the binarization control is performed. If the data is '0', a logic 'high' state is generated for 0.56 milliseconds and a logic 'low' state for 0.56 milliseconds.

)가 연속적으로 발생됨을 알 수 있다.For example, assuming that the unique data (Custom) is '10100100' and the main power supply of the corresponding device is to be controlled, the control data (Data) is '00000001' as shown in FIG. Therefore, as shown in FIG. 9D, after the unique data Custom of '10100100' is repeatedly outputted continuously, the control data Data of '00000001' and the inversion control data of '11111110' (

It can be seen that is generated continuously.

Next, the pulse waveforms shown in Figs. 10A to 10F show the control data and the pulse signal transmitted through the infrared light emitting diode 16 when the joystick 3 of the joystick integrated remote controller is operated.

As shown in FIG. 10A, as the user operates various function keys, the microcomputer 14 generates a predetermined pulse signal corresponding to the corresponding binarization control data according to the classification of the binarization control data as shown in FIG. Occurs. This pulse signal is repeatedly outputted with a period of 108 milliseconds of transmission time Trans and 100 milliseconds of waiting time Wait. At this time, the above-described wait time of 100 milliseconds (Wait) is a time required to recognize that the control data received from the target device is control data by the operation of the joystick 3, as shown in FIG. This time is set so that it can be arbitrarily changed according to the precision of the corresponding device and the control data transmission capability of the joystick integrated remote controller.

Further, when the pulse signal is subdivided, as shown in FIG. 10C, a pair of 9 milliseconds of a leader indicating that a pulse signal is transmitted and a pair of 8 bits each representing a unique code of a manufacturer who manufactures the product are provided. Custom data, 8-bit first control data (X Data) capable of controlling the position of the point displayed on the target device when the joystick 3 is operated in the up-down direction, and the joystick 3 The second control data (Y Data) of 8 bits that can control the position of the point displayed on the target device when the operation in the left and right directions are sequentially generated.

Here, as shown in FIG. 10D, when the joystick 3 is operated to indicate that the first bit of the 8-bit first control data X data is control data generated by manipulating the joystick 3. '1' is always set to occur, with the second bit representing the positive and negative directions. That is, when the second bit is '0', it indicates that the joystick 3 is operated in the upward direction, and therefore, the point displayed on the target device is moved upward. If the second bit is '1', the joystick 3 indicates the operation in the downward direction, and therefore, the point displayed on the target device is moved downward.

In addition, the remaining six bits except the data of the first and second bits represent the amount of operation of the joystick 3. This manipulated value is related to the moving speed of the point displayed on the target device.

Meanwhile, as shown in FIG. 10E, when the joystick 3 is manipulated to indicate that the first bit of the 8-bit second control data Y Data is control data generated by manipulating the joystick 3. '1' is always set to occur, with the second bit representing the positive and negative directions. That is, when the second bit is '0', it indicates that the joystick 3 is operated in the left direction, and therefore, the point displayed on the target device is moved in the left direction. If the second bit is '1', the joystick 3 indicates an operation in the right direction, and therefore, the point displayed on the target device is moved in the right direction.

In addition, the remaining six bits except the data of the first and second bits represent the amount of operation of the joystick 3 as in the case of the first control data. This manipulated value is related to the moving speed of the point displayed on the target device.

As a result, the first control data (X Data) determines whether the moving direction of the joystick 3 has moved in the upper direction or the lower direction, and at the same time determines the moving speed of the point, and the second control data (Y Data). Is determined to determine which direction the moving direction of the joystick 3 has moved in the left direction and the right direction, and at the same time determines the moving speed of the point. However, it is apparent that the object determined by the first control data and the second control data may be changed for convenience.

For example, when the unique code is '10100100', the first control data (X Data) is '10111110', and the second control data (Y Data) is '11110001', the infrared light emitting diode 16 from the microcomputer 14 is used. The control data format that is transmitted in the following) is shown in FIG. 10F. Here, the joystick 3 is not operated only by the displacement of any one of the upper, lower, left, and right, but the displacement of any one of the upper and lower sides and the displacement of any of the left and right sides can be simultaneously operated. The first and second control data (X Data, Y Data) may occur differently from each other. Accordingly, the target device divides and detects the first and second control data (X Data, Y Data), respectively, and each operation direction and the manipulation amount from the divided first and second control data (X Data, Y Data), respectively. After calculating, and combining the calculated operation direction and the manipulated variable, the point is moved in an arbitrary direction and speed according to the synthesized data. Therefore, the joystick 3 can be used to easily control the position of the point displayed on the target device.

<Other Embodiments of the Present Invention>

Another embodiment of a joystick integrated remote controller according to the present invention will be described with reference to FIGS. 11 to 14. In FIGS. 11 to 14, the same reference numerals as used in FIGS. 1 to 10 denote the same components, and thus redundant description thereof will be omitted.

First, referring to FIGS. 11 and 12, a structure of a joystick and a printed circuit board according to another embodiment of the present invention will be described. The upper end of the printed circuit board 4, that is, the contact portion 7 of the joystick 3 will be described. 12A, conductive thin films 9d, 9e, 9f, and 9g having a substantially circular shape and divided into four regions are printed on the printed circuit board 4. Here, a pair of conductive thin films 9d, 9e, 9f, and 9g are printed spaced apart from each other, and a pair printed on the central portion of each area of the printed conductive thin films 9d, 9e, 9f, and 9g. Resistors 10d, 10e, 10f, and 10g for connecting the conductive thin films 9d, 9e, 9f, and 9g are coated.

On the other hand, the back structure of the printed circuit board 4 is the same as in Fig. 3b described above.

An operation of a joystick integrated remote controller according to another embodiment of the present invention having the configuration as described above will be described with reference to FIGS. 13 and 14. In the description of the operation of the joystick-integrated remote controller according to another embodiment of the present invention to be described later, it will be described in detail referring to the above-described Fig. 4 and 5 and 7.

When the user operates the joystick 3 mounted on the joystick integrated remote controller by a predetermined displacement, the thin film conductors 8a and 8c of the joystick 3 are in all directions with the conductive thin film 12 printed on the printed circuit board 4. Among the divided pairs of conductive thin films 9d, 9e, 9f, and 9g, contact is made to a predetermined range corresponding to an operation amount of the joystick 3.

Accordingly, the driving voltage Vcc supplied from the main power source is supplied to the conductive thin film 12 through the main power connection terminal 13, and then the conductive thin film of the thin film conductors 8a and 8c and the printed circuit board 4 is supplied. The driving current flows through the thin film conductors 8a and 8c having low resistance to the point where (9d, 9e, 9f, 9g) is in contact, and the conductive thin films 9d, 9e and 9f having high resistance after the contact point described above. , 9g) flows the driving current.

For example, when the user manipulates the joystick 3 a lot, the thin film conductors 8a and 8c of the joystick 3 are printed on the conductive thin film 12 of the printed circuit board 4 and the conductive thin film 9d and the inner periphery. 9e, 9f, 9g) and the conductive thin films 9d, 9e, 9f, 9g printed on the outer periphery are brought into contact at the same time, so that the total resistance of the joystick 3 has a low resistance value (about 50 kV).

On the contrary, when the user manipulates the joystick 3 less, the thin film conductors 8a and 8c of the joystick 3 are printed on the conductive thin film 12 of the printed circuit board 4 and the conductive thin film 9d. , 9e, 9f, and 9g only, the total resistance value of the joystick 3 has a high resistance value (approximately 50 mA).

Therefore, the amount of current flowing through the microcomputer 14 changes differently according to the operation amount of the joystick 3, and this current is supplied to the capacitors C1 to C4 shown in FIG. Here, since the resistors 10, 10a, 10b, and 10c and the capacitors C1 to C4 by the joystick 3 show the configuration of the RC time constant circuit, the microcomputer 14 is finally connected to FIGS. 5A and 5B. The same pulse waveform is input.

At this time, since the microcomputer 14 set the voltage threshold value (threshold voltage value) to 0.7 Vcc as described above, the pseudo pulses output from the microcomputer 14 are as shown in Figs. 5C and 5D.

Here, the control data according to the operation state of the joystick integrated remote controller according to another embodiment of the present invention is shown in FIG.

As shown in Fig. 13, it shows a state in which control data is allocated corresponding to the operation direction and the operation amount of the various function keys 2 and joystick 3 operable by the user. Here, the control data corresponding to various functions selected by the user may be set differently for each manufacturer without following the rules of FIG. 13, and may not have any regularity. However, in another embodiment of the present invention, for convenience, the control data is set to '001101XX' or '001110XX' (where X is either '0' or '1') so as to recognize that the joystick 3 is operated. The remaining part is set to recognize that the function key 2 is operated.

In addition, when the operation amount of the joystick 3 is small, the rising time of a pulse exists in the range of about 5.0-25.0 by the RC time constant circuit shown in FIG. In this case, the microcomputer 14 can easily know the operation direction of the joystick 3 according to which of the plurality of terminals a pulse having a rising time of 5.0 to 25.0 is input. For example, when a pulse is input to a predetermined terminal of the microcomputer 14 connected to the connection terminal 11 of the printed circuit board 4, the microcomputer 14 determines that the joystick 3 is operated upward. According to the contrast table shown in 13, control data ('00111000') for moving the point of the target device upward is generated, and the microcomputer 14 connected to the connection terminal 11a of the printed circuit board 4 When a pulse is input to a predetermined terminal, the microcomputer 14 determines that the joystick 3 has been operated in the downward direction, and generates control data ('00111001') for moving the point of the target device downward. When a pulse is input to a predetermined terminal of the microcomputer 14 connected to the connection terminal 11b of the circuit board 4, the microcomputer 14 determines that the joystick 3 has been operated in the left direction and determines the point of the target device. Left room After generating control data '00111010' for moving to a predetermined terminal and a pulse is input to a predetermined terminal of the microcomputer 14 connected to the connection terminal 11d of the printed circuit board 4, the microcomputer 14 uses a joystick ( 3) is determined to be operated in the right direction, and generates control data ('00111011') for moving the point of the target device in the right direction.

In addition, when the operation amount of the joystick 3 is large, the rising time of a pulse exists by the RC time constant circuit in the range of about 0.0-5.0. In this case, the microcomputer 14 can easily know the operation direction of the joystick 3 according to which of the plurality of terminals a pulse having a rising time of 0.0 to 5.0 is input. For example, when a pulse is input to a predetermined terminal of the microcomputer 14 connected to the connection terminal 11 of the printed circuit board 4, the microcomputer 14 determines that the joystick 3 has been operated in the upward direction. When the control data ('00110100') for increasing the channel of the device is generated and a pulse is input to a predetermined terminal of the microcomputer 14 connected to the connection terminal 11a of the printed circuit board 4, the microcomputer 4 Determines that the joystick 3 has been operated in the downward direction to generate control data ('00110101') for reducing the channel of the target device, and the microcomputer connected to the connection terminal 11b of the printed circuit board 4 ( When a pulse is input to a predetermined terminal of 14), the microcomputer 14 determines that the joystick 3 has been operated in the left direction, and generates control data ('00110110') for increasing the volume of the target device. Connection of the board 4 When a pulse is input to a predetermined terminal of the microcomputer 14 connected to the terminal 11c, the microcomputer 14 determines that the joystick 3 has been operated in the right direction so that the control data for reducing the volume of the target device (' 00110111 ').

Accordingly, the microcomputer 14 detects the corresponding control data among the allocated control data as shown in FIG. 13 and transmits the corresponding control data through the infrared light emitting diode 16. In addition, since the same decoding data as that of FIG. 13 is set in the target device on the receiving side, it is possible to perform the corresponding function to be controlled by receiving the control data transmitted from the infrared light emitting diode 16 and comparing it with the decoded data.

On the other hand, the control data format transmitted from the infrared light emitting diode 16 is the same as in Figs. Here, when the various function keys 2 of the joystick integrated remote controller according to another embodiment of the present invention are operated, the control data and the pulse signal transmitted through the infrared light emitting diode 16 are the same as in FIG.

Next, the data format shown in FIGS. 14A to 14F shows the control data and the pulse signal transmitted through the infrared light emitting diode when the joystick 3 of the joystick integrated remote controller according to another embodiment of the present invention is operated. will be.

As shown in FIG. 14A, as the user operates various function keys 2, the microcomputer 14 generates a predetermined pulse signal corresponding to the control data according to the classification of the control data as shown in FIG. do. Since the format of this pulse signal has already been described above with reference to FIG. 10, redundant description is omitted.

Meanwhile, as shown in FIG. 14D, the first to sixth bits of the eight bits of first control data (X Data) are used to indicate that the joystick 3 is control data generated by manipulating the joystick 3. In case of the operation, '001101' or '001110' is set to be generated, and the seventh and eighth bits indicate the moving direction of the point displayed on the target device, and the increase and decrease of the channel and the volume. That is, when the first to sixth bits are set to '001101', the channel and volume are increased or decreased, and when the first to sixth bits are set to '001110', the movement direction of the point is indicated.

In addition, in the channel and volume increase and decrease state, the seventh and eighth bits are '00', the channel is increased, '01' is the channel decrease, '10' is the volume increase, and '11' is the volume decrease.

In addition, in the movement direction control state of the point, if the seventh and eighth bits are '00', the point moves upward. If '01', the point moves downward. Indicated to move leftward, '11' indicates to move the point to the right.

On the other hand, as shown in Fig. 14E, the 8-bit second control data (Y Data) has the same structure as the above-described first control data (X Data).

For example, when the unique data (Custom) is '10100100', the first control data (X Data) is '00111000', and the second control data (Y Data) is '00111010', infrared light is emitted from the microcomputer 14. The control data format transmitted to the diode 16 is shown in Fig. 14F. Here, the joystick 3 is not operated only by the displacement of any one of the upper, lower, left, and right, but the displacement of any one of the upper and lower sides and the displacement of any of the left and right sides can be simultaneously operated. The first and second control data (X Data, Y Data) may occur differently from each other. Accordingly, the target device divides and detects the first and second control data (X Data, Y Data), respectively, and each operation direction and the manipulation amount from the divided first and second control data (X Data, Y Data), respectively. After calculating, and combining the calculated operation direction and the manipulated variable, the point is moved in an arbitrary direction and the channel and the volume are increased or decreased according to the synthesized data. Therefore, the joystick 3 can be used to easily control the position, channel, and volume of the point displayed on the target device.
