Abstract

PURPOSE:To obtain a remote controller in which a preliminarily stored remote control signal can be selected and set by a simple method without any troublesome preparing work, and even a malfunction can be prevented. CONSTITUTION:This device is equipped with a signal setting switch 1 which sets an already stored remote control signal. At the time of turning on the signal setting switch 1, a specific control button provided at the remote controller is functioned as a signal setting means 2 which selects the appropriate remote control signal, and at the time of turning off the signal setting switch 1, the setting of the remote control signal is ended. And also, at the time of setting the remote control signal, a malfunction preventing means 3 is operated so that an unintended signal can not be generated even when a switch or a button on the remote controller is unwillingly pressed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote control device for remotely controlling various electric appliances.

[0002]

2. Description of the Related Art A conventional general-purpose remote control device has a learning function of reading and copying a remote control signal of a hand-held remote control device in order to provide versatility. Further, in a remote control device of a type in which a main remote control signal is stored in advance, a required remote control signal is selected and set by performing a composite operation such as simultaneously pressing a plurality of buttons.

[0003]

However, in the above-mentioned prior art, since the means for reading the remote control signal of another remote control device and the method for setting the stored remote control signal are very complicated and troublesome, an erroneous operation is induced. It has a problem that it is easy to do. Therefore, the present invention solves such a problem, and an object thereof is to provide a remote control device capable of setting a remote control signal stored in advance by a simple method which omits troublesome preparation work. It is in.

[0004]

As shown in FIG. 1, a remote control device of the present invention includes a signal setting switch 1 for setting a stored remote control signal.
By turning on the signal setting switch 1, a specific operation button provided on the remote control device functions as a signal setting means 2 for selecting an appropriate remote control signal.
Turn off to complete the remote control signal setting. Further, when setting the remote control signal, the malfunction preventing means 3 works so as not to generate an unintended signal even if a switch or button on the remote control device is inadvertently pressed.

[0005]

With such a structure, the remote control signal can be set easily and safely by the signal setting means 2 and then switched to the normal use.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the remote control device of the present invention will be described below. FIG. 2 is a perspective view showing the external appearance of the remote control device of the present invention.
Operation button 12 by switching 1 to setting mode
Specific button (eg, power on / off button)
The button 13 has a setting function and is also used as a setting operation button 13 and is used for remote control signal setting. The setting work is completed by switching the mode selector switch 11 again to the normal mode. When the operation button 12 is pressed in the normal mode, the infrared light emitting diode 14 transmits a remote control signal corresponding to each operation button.

FIG. 3 is a circuit block diagram showing a specific example of a control device used in the remote control device of the present invention, which is composed of a microcomputer 21 and its peripheral circuits. The microcomputer 21 shown here is C
It is a one-chip microcomputer including a PU, a RAM, a ROM and an input / output port. The switch 22 corresponds to the mode changeover switch 11, and its setting state is discriminated inside the microcomputer 21. When the switch 22 is switched to the setting mode, only the specific key in the key matrix 23 is valid and used for setting the remote control signal. At this time, keys that are not used for signal setting are disabled, and even if the operation button 12 is pressed, the infrared light emitting diode 26 does not transmit a remote control signal. Switch 22
When the operation is switched to the normal mode again and the setting operation is finished and any operation button 12 is pressed, it is detected in the microcomputer 21 that the contact portions 24 corresponding to the respective ones in the key matrix 23 are energized. Output the corresponding remote control signal. The remote control signal is amplified by the transistor 25, and the infrared light emitting diode 26 converts the current change into infrared rays and transmits the infrared rays. Here, 27 is a base current limiting resistor of the transistor 25, 28 is a forward current limiting resistor of the infrared light emitting diode 26, 29 is a clock oscillator of the microcomputer 21, and 30 and 31 are oscillation capacitors.

Next, the operation of setting the remote control signal of the remote control device configured as described above will be described with reference to the flowchart shown in FIG.
Here, a television remote control device that stores remote control signals corresponding to 10 manufacturers will be described as an example. Mode switch 1
When 1 and 22 are switched to the setting mode, the first maker is initially selected (steps 41 and 42). In the setting mode, only the power on / off button 13 is enabled, and even if the other operation buttons 12 are pressed, no transmission is performed and the power button is disabled. When the power-on / off button 13 of the remote control device is pressed in this state, a remote control signal corresponding to power-on of the first manufacturer television is transmitted (steps 43 and 44). If the television owned by the user does not respond, the power-on / off button 13 of the remote control device is pressed again, and the remote control signal corresponding to the second manufacturer is transmitted. Similarly, each time the power on / off button 13 is pressed 3 times, 4 times, 5 times, the remote control signal corresponding to each maker is sent to the third, fourth, fifth, and up to the tenth. Then, the process returns to No. 1 again (steps 45 and 46). When the power-on / off button 13 is pressed several times, the second time becomes invalid unless the fixed time interval is opened between the first time and the second time, and the second time is judged as the second time. The interval is controlled by the microcomputer 21 so that the user can recognize that the operation button 12 has been pressed surely, thereby preventing malfunction due to careless operation. On the way
When the television owned by the user reacts to the transmitted remote control signal and the power is turned on, the mode changeover switches 11 and 22 are switched to the normal mode and the manufacturer setting is completed (steps 46 and 47). At this time, the manufacturer of the number corresponding to the remote control signal transmitted before switching the mode changeover switches 11 and 22 from the setting mode to the normal mode is set. As described above, by simply performing a simple operation according to the procedure shown in the flowchart of FIG. 4, even if the user is not particularly aware of the manufacturer, the remote control signal suitable for the television owned by the user can be surely selected. You can set the manufacturer. Further, the idea of the setting method is the same even if the television shown here is replaced with another electric appliance.

[0009]

The remote control device of the present invention is
As described above, the mode changeover switch for signal setting is provided,
Controlling with a microcomputer has an advantage that a remote control signal stored in advance can be selected and set by a simple and reliable method. Since it is not necessary to perform a combined operation of pressing a plurality of operation buttons at the same time, there is also an advantage that an operation with one hand is possible.
