Abstract

PURPOSE:To easily enable the setting of a remote control code without reading the instructions by automatically and successively calling a remote control cord and performing a retrieval setting at the time of setting the remote control cord, in a remote control device storing the remote control cord for controlling plural object equipments. CONSTITUTION:For instance, a left below key is defined as a retrieval key. By depressing the retrieval key, a retrieval mode is entered. At this stage, an initial value is substituted for a variable A. The variables correspond to the remote control cords where No. 1 is an A company, No. 2 is a B company and No. 3 is a C company, ..., etc. When a power source key is depressed, the power source cord of the maker set by the variable A is transmitted. If the operation of an equipment is confirmed by a user during a certain waiting time, the state is returned to a standby state by separating a power source key. When the operation of an equipment does not exist, the power source key continues to be depressed and the same work is repeated by the number of the maker registered in a memory by adding numbers one by one to the variable A. Therefore, the hardware of a remote control device remains as in conventional one.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a remote controller which can be used for various target devices, and more particularly to a remote controller which searches and sets a necessary remote controller code.

[0002]

2. Description of the Related Art FIG. 2 shows a plan view of a conventional remote controller.
A remote controller 1 is provided with various keys such as a power key and a Ch key as shown in the figure. FIG. 3 is a block diagram of the remote controller 1 and the input unit of the TV 2 controlled by the remote controller 1.

When any one key of the remote controller 1 is pressed,
The CPU transmits a remote control code corresponding to the key from the output port using an optical device (usually an infrared light emitting diode) or the like. The TV 2 side receives a code from the remote controller 1 by a light receiving section (photocoupler) or the like, recognizes it by the microcomputer of the TV body, and operates based on the recognition.

Among remote controllers, there is a remote controller that can be handled by one remote controller even if the manufacturers are different. FIG. 4 is a flow chart when calling the manufacturer code of the conventional remote controller compatible with each manufacturer.

Step S1 is a key judgment program including key input, step S2 is a code transmission program, and step S3 is a judgment of double pressing of another key when the power key is received (press simultaneously with the power key and other keys). Step S4 is a program for calling the manufacturer code corresponding to the key accepted in step S3.

[0006] The conventional remote controller settings for each manufacturer are as follows:
It is configured to operate as in FIG. If the remote control code for company A is currently set and the remote control code for company B is to be called next, the user first presses the power key on the remote control. Then, in step S1, it is determined that the key is the power key. Next, in step S2, the power cord of the manufacturer currently set is transmitted.

Next, while pressing the power key, a key corresponding to company B (for example, Ch1 key) is pressed. Then, the key is determined in step S3, the maker code corresponding to the key determined in step S3 is set in step S4, and the power supply code of the maker set in step S4 is transmitted in step S2. The user confirms that the remote control code has changed to company B and completes (confirms that the device of company B corresponding to the remote control operates).

Explaining the X key in step S3, in the conventional method, when the power key is pressed while another key is pressed, the remote controller maker code changes, but it is pre-programmed, for example, the Ch1 key- --Company B Ch2 key --- Company A (while holding down the power key). Therefore, the X key means any of these set keys.

[0009]

Since the conventional remote controller for each manufacturer is constructed as described above, when setting the remote controller code such as the manufacturer code, it is necessary to check the key corresponding to each manufacturer according to the instruction manual or the like. Or
It is necessary to point the remote control at the device to be operated and press each key until it operates, and change it.
There was a problem that the same work had to be performed when replacing the battery.

The present invention has been made in order to solve the above problems, and can be easily set even if a user's manual or the like is lost when setting a remote control code such as a manufacturer code. It is intended that the (inlay, fitted display plate) can be omitted.

[0011]

EXAMPLES Example 1. FIG. 1 is a flow chart showing an embodiment of the present invention. Step T1 is for determining whether or not a search mode has been entered, step T2 is for inputting an initial value to variable A, and step T3 is for the user to press the power key on the remote controller. It is determined whether or not, step T4 sets the manufacturer code indicated by the variable A, step T5
, The power cord of the manufacturer set in step T4 is transmitted.

Step T6 waits until the next maker code is called, and step T7 increments the variable A by one. In step T8, it is determined whether the variable A exceeds the preset number X of manufacturers, and step T8.
10 determines whether or not the search mode has ended. Steps T9 and T11 show the standby state of the remote controller.

Next, the operation will be described. From the remote control standby state of START, it is determined in step T1 whether or not the manufacturer code search mode has been entered. As a means for entering this mode, for example, the lower left key in FIG. 2 is used as a search key to shift to the search mode. If this key is not pressed, the procedure goes to the remote controller standby state in step T9, and if it is pressed, the search mode is entered. At step T2, the initial value is substituted for the variable A, and at step T3 it is determined whether or not the power key is pressed. If it has not been pressed, a loop is made between step T10 and step T3 for determining whether or not to end the search mode.

If it is determined in step T3 that the power key has been pressed, the remote control code is set to the manufacturer corresponding to the variable in step T4. Then, in step T5, the power cord of the manufacturer set in step T4 is transmitted. In step T6, a time waiting is provided so that the user can confirm whether or not the device to be operated is operating. If the user confirms the operation of the device, it is the manufacturer code to be searched, so release the power key. The program goes through steps T7, T8, T3 (or steps T7, T8, T2, T3), enters the search mode end determination loop at step T10, presses the search mode key and enters the remote controller standby state, and the operation is completed. To do.

If there is no equipment operation, the user continues to press the power key. After finishing the time waiting in step T6, 1 is added to the variable A to call the next maker in step T7. Remote control 1 at step T8
It is determined whether or not the number of manufacturers stored in the internal memory (X is set here) has been exceeded. If the number has been exceeded, the process returns to step T2, variable A is returned to the initial value, and the above work is performed. repeat. If not exceeded, the process returns to step T3 and the same work is repeated. As described above, the hardware of the conventional remote controller can be supported by only software without modification.

The variable A is usually set by software. For example, if it is set as 1 --- A company, 2 --- B company, 3 --- C company, and 1 is put in the variable A, it means that it is the remote control code of A company, and as shown in the flow chart of FIG. 3.3. ... are sequentially searched.

Example 2. In the above embodiment, the search mode key is used as the means to enter the search mode. However, when a plurality of keys are simultaneously pressed, for example, when the search mode key and the power mode key are double pressed, or the number of keys is reduced. Therefore, the search mode may be entered when the mute key and the volume key are pressed (double pressed) at the same time. Alternatively, a password or the like may be used.

Example 3. In the above embodiment, when the number X of stored manufacturers is exceeded, the variable A is returned to the initial value in step T8 and the same operation is performed again. However, it is determined that there is no compatible manufacturer, and the search mode is set. You may make it complete | finish.

Example 4. In the above embodiment, it is difficult to know whether the search mode has been entered, so steps T1 and T2 are performed.
A search mode display (for example, a lamp or the like) may be added in between.

Example 5. In the above-described embodiment, an example in which the manufacturer code is used as the remote control code has been shown. However, when the code other than the manufacturer code, for example, the code for each device is different, the code for each device may be supported.

[0027]

As described above, according to the present invention, when the remote control code is set, the remote control codes are automatically called to perform search setting, so that the remote control code can be easily read without looking at the instruction manual. There is an effect that can be set.
