Say the device can.

FIG. 1 is a diagram illustrating an operating state between a conventional remote controller 100 and an electronic device 200. As shown in FIG. 1, the remote controller 100 includes a key matrix circuit 10, a key driver 12, a memory 14, a controller 16, and a light emitter 18. 200 includes a receiver 20, a memory 22, a system controller 24, and a function command processor 26.

Referring to FIG. 1, the key matrix circuit 10 includes a function key and a mode for controlling a power key (power ON / OFF), numeric keys (0-9), and various functions (mute, surround, section, etc.). It consists of a changeover key (TV / VCR). Therefore, when a user presses a function key of the key matrix circuit 10, the key driver 12 generates a corresponding key signal and provides the same to the controller 16. On the other hand, the memory 14 stores code control data corresponding to various buttons (keys) of the key matrix circuit 10. The controller 16 responds when a predetermined function key signal is input from the key driver 12. The code control data to be read from the memory 14 is provided to the light emitting unit 18.

In this way, the switching element Q1 can be repeatedly turned on and off, and the infrared code data is transmitted to the electronic device 200.

The electronic device 200 receives and amplifies the infrared control data transmitted from the light emitting unit 18 of the remote controller 100 and provides it to the system controller 24. The memory 22 stores operation commands of various buttons (keys) corresponding to code control data.

Therefore, the system controller 24 recognizes the infrared code data amplified by the receiver 20 and reads a function command corresponding to the recognized infrared code data from the memory 22 to control the function command processor 26. The function command processor 26 performs a function command by the control signal recognized by the system controller 24. In the conventional remote controller configured as described above, when the user uses a conventional remote controller having a large number of function buttons (keys), the user not only has to find and operate the corresponding button one by one, but especially in the case of a child or an elderly person, The button marked with the letter could not be operated easily.

In addition, many buttons installed in the remote controller are acting as a factor to increase the production cost when manufacturing the remote controller. Accordingly, the present invention has been made in order to solve the above disadvantages, and set a plurality of function buttons as one representative button, and a simple remote controller to accommodate a plurality of functional operations by using the set representative button The purpose is to provide.

In order to achieve the above object, the present invention provides a super simple remote controller for remotely controlling a function of a predetermined electronic device; A simple command applying unit for generating key signals corresponding to a plurality of function commands for operating the electronic device; A memory unit which stores code data corresponding to the plurality of functions in response to a command; On the basis of the number of occurrences of the key signal input within a preset time and the holding time of the generated key signal, contents of a function command for operating the electronic device are determined, and code data corresponding to the determined function command is determined. A control unit which reads from the memory unit and outputs the same; And a light emitting unit for transmitting the code data to the electronic device.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the illustrated drawings.

2 shows an internal block diagram of the ultra-simple remote controller according to an embodiment of the present invention and a block diagram of an electronic device. As shown in FIG. 2, the ultra-simple remote controller according to the embodiment of the present invention substantially sets a plurality of function buttons as one representative button in the conventional remote controller shown in FIG. A simple command applying unit 34 capable of accommodating a plurality of functional operations by using the representative representative button, a tone generating circuit unit 36 for generating a tone of a voice corresponding thereto when a predetermined function command is applied, and a voice It further comprises a voice processing output unit 38 for processing the tone of the voice signal to provide to the speaker (sp).

Therefore, hereinafter, the description will focus on the constituent members further added in the embodiment of the present invention. Referring to FIG. 2, the user applies a predetermined function command to the control unit 34 through the simple command applying unit 34. At this time, taking the case where the electronic device 200 is a VCR will be described the general operation of the ultra-simple remote controller of the present invention as follows. In order to set the VCR to the Play mode, the user presses the representative button of the simple command application unit 34 shortly (.) Once, and in the case of setting to the double speed mode, Long press once (。-). And, in case of rewind, press (。。-) once shortly twice long. The simple command applying unit 34 generates a signal corresponding thereto and provides the same to the control unit 37.

The control unit 37 counts the number of times of input of the signal input from the simple command applying unit 34 and the duration of the input signal once, and then based on the combination of the number of times of input and the duration of the input signal once. To determine the function of the input signal. When the signal input from the simple command application 34 is determined, the control unit 37 reads code control data corresponding to the signal from the memory 35.

The control unit 37 provides the code control data to the switching element Q1 via the protection resistor R2 of the light emitting unit 33, and thus the switching element Q1 is turned on / off corresponding to the code data. Will perform the action.

The power applied from the standby power supply terminal B2 + receives power from the standby power supply terminal B2 + when the switching device Q1 is on, turns on the light emitting device LED2, and simultaneously turns off the switching device Q2. At this time, since the power is cut off from the standby power supply terminal B2 + to turn off the light emitting device LED2, the light emitting device LED2 transmits predetermined infrared code control data to the electronic device 400.

Therefore, the receiving unit 20 of the electronic device 400 receives the infrared code control data transmitted from the light emitting unit 33 and amplifies this data at the same time as the receiving unit 20 and then provides the system control unit 24 of the electronic device. Done. The code control data input from the system control unit 24 is recognized, and a function command corresponding to the recognized result is read out from the memory 22. The system controller 24 transmits the function command processor 26 to perform the function command. The function command processing unit 26 is to perform the operation of the electronic device corresponding thereto.

Prior to this, a command corresponding to a function command selected by the user is transmitted to the tone generating circuit unit 36 through the control unit 37 of the ultra-simple remote controller, and at the same time, the tone generating circuit unit 36 generates a voice tone corresponding to the function command. It is generated and delivered to the control unit 37. Subsequently, the control unit 37 provides the audio tone corresponding to this function command to the audio processing output unit 38. The voice processing output unit 38 modulates the voice tone provided from the control unit 37 into voice recognizable by the user and amplifies a voice signal corresponding to the modulated function command.

This voice signal is output through the speaker sp installed in the remote controller for a very short time. Therefore, the user can easily check whether the function command selected by the user is correctly transmitted through the light emitting unit 33.

For example, when the electronic device 200 is a VCR, when the user does not operate the key metrics circuit 31 and wants to set the play mode of the VCR by the simple command applying unit 34, the user Press a short (.) Once through the representative button of the simple command application unit 34, and accordingly the signal is transmitted to the control unit 37. The control unit 37 searches for a signal input from the simple command applying unit 34, and performs a playback function of the VCR when the signal input from the simple command applying unit 34 is a signal pressed briefly (.) Once. The code control data (for example, 00110011) is read from the memory 35 by the command signal.

The code control data read out from the memory 35 (eg, 00110011) remains on the light emitting unit 33 through the control unit 37. In this case, the code control data used as an example is a light emitting element (LED2) of the light emitting unit 33. ) Will blink. Therefore, the infrared code control data corresponding to the function command already promised is transmitted.

On the other hand, the control unit 37 detects the tone signal for notifying the performance of the VCR playback function from the tone generating circuit unit 36 and provides it to the voice processing output unit 38, and the voice processing output unit 38 notifies the performance of the VCR playback function. Tone signal for processing the signal provided to the speaker (sp).

In the embodiment of the present invention, the functional operation of the simple command application unit 34 has been described by taking the VCR as an example, but it can be extended to a range usable by the operation user, and can be used as the existing key metrics circuit 31.
