Abstract

PURPOSE:To widen the application range of a remote controller by providing a second electromagnetic wave signal output means outputting a set electromagnetic wave signal when count time is compared with a preset time and the count time reaches the preset time. CONSTITUTION:When timer interruption is applied to a CPU 9, a timer 12 is reset, a second is counted and timer time is advanced by one second. The timer time corresponds to reservation time and the accumulating time in which present time or the preset time is made zero can be used. And it is judged whether the timer time reaches the reservation time. When it is judged that the timer time reaches the preset time, the command based on reservation contents is output to an input and output port 7 and infrared radiation which the information of the command indicates is output from a infrared radiation LED 6 while the preset time and the preset contents are released to end the operation.

The amplification detector 8 is connected to the light receiving diode 15, amplifies and detects the infrared rays obtained from the light receiving diode 15, and outputs a detected signal to the input/output coupler. The CPU 9 recognizes (learns) infrared data such as the frequency of the infrared rays received by the diode 15 by analyzing the detection code according to a program showing a learning procedure stored in the ROM 10, and stores it in the RAM I 1. Then, based on the infrared data stored in the RAMII, infrared rays having the same frequency as the recognized infrared ray can be outputted from the infrared LED 6.

Then, in step S3, a command based on the infrared data is transmitted to the input/output port door, and the infrared light indicated by the command information is outputted from the infrared @LED 6.

[Problem to be solved by the invention]

Conventional remote controls are configured as described above, and infrared rays are output only when a key is pressed. Therefore, there was a problem that the range of application of the remote control was narrow.

This invention was made to solve the above-mentioned problems, and aims to provide a remote control with a wide range of applications.

[Means to solve the problem]

A remote control device according to the present invention is a device that controls a remote device by outputting an electromagnetic wave signal to a receiving section of the device, and includes a clock means for counting time and calculating a count time, and an external device. a reservation time setting means that can manually set a reservation time; an electromagnetic wave signal setting means that can set a set electromagnetic wave signal, which is an electromagnetic wave signal to be output when the reservation time has elapsed, by external human power; and a first electromagnetic wave signal output means that outputs a predetermined electromagnetic wave signal in response to the external input, and compares the count time and the reserved time, and when the count time reaches the reserved time, the and second electromagnetic wave signal output means for outputting a setting electromagnetic wave signal.

[Effect]

The second electromagnetic wave signal output means in this invention compares the count time and the reserved time and outputs the set electromagnetic wave signal when the count time reaches the reserved time. Therefore, by appropriately setting the reservation time using the reservation time setting means, it is possible to automatically output the set electromagnetic wave signal set by the electromagnetic wave signal setting means at a desired time.

[Embodiment] FIG. 1 is a block diagram showing a remote control with a learning function which is an embodiment of the present invention. As shown in the figure, a timer 12, a liquid crystal display section 4, and a control section 5 for the liquid crystal display section 4 are newly provided.

The timer 12 and the control unit 5 are connected to the C via the I10 bus 14.
Connected to PU9. Timer 12 becomes 1 when activated.
Counts time every second, and CPU every second counts.
Apply a timer interrupt to 9. Based on instructions from the CPU 9, the control unit 5 displays a timer time, which will be described later, on the liquid crystal display unit 4.
a scheduled time indicating the time when the remote control will automatically operate;
The contents of the reservation, etc. showing the operating procedure at that time are displayed.

In addition, these count times, reservation times, and reservation details are provided by RA.
Stored in MII.

The other configurations are the same as the conventional one, so explanations will be omitted. Further, the reservation time and reservation contents are set by inputting the keys of the key matrix 1 while looking at the liquid crystal display section 4, in the same manner as the reservation operation of a conventional VTR or the like. - Once the time, reservation time, and reservation details are set, the timer 12 becomes operational.

FIG. 2 is a flowchart showing the operation procedure of the remote control in the timer interrupt mode.

The operating procedure will be described below with reference to the same figure.

When the timer interrupt is applied to the CPU 9, step S11
Then, reset the timer 12 and count the passage of 1 second,
In step S12, the timer time is advanced by 1 second. The timer time is a time corresponding to the reservation time, and can be the current time or a cumulative time with the reservation time as O.

Then, in step S13, it is determined whether the timer time has reached the reserved time. When it is determined that the timer time has reached the reserved time, in step s14, a command based on the reservation details is output to the turnout capo door, the infrared rays indicated by the command information are outputted from the infrared LED 6, and the reserved time and Cancels the reservation details and ends the operation. On the other hand, if it is determined that the timer time has not reached the reserved time, the operation is ended without doing anything. The timer interrupt mentioned above is
As described above, the reservation time and reservation contents are performed at one-second intervals until the reservation is canceled.

In this way, when a remote control is provided with a timer function, it can be used for the following purposes, for example.

Programs received on a satellite broadcast tuner (DBS) are
When recording with a VTR that does not have a built-in S, DBS channel selection is performed using the reservation function of the remote control of this embodiment, and external manual reservation of the VTR is performed using the answering machine function of the VTR itself.

By using the above, consecutive D
Recording of BS programs can be done even with a VTR that does not have a built-in DBS. Further, the same thing can be done when recording a program received by an FM tuner onto a cassette deck or the like. Furthermore, since it has a learning function, no matter what manufacturer the device is manufactured by, if the device operates by receiving infrared rays that meet predetermined conditions, the remote control of this example can be used to set the timer. Operation becomes possible.

In this way, the remote controller of this embodiment has a wider range of applications than the conventional remote controller. Further, as in the conventional case, it is of course possible to output infrared rays in response to the human input of a key (the operation shown in FIG. 4).

Although this embodiment shows a remote controller that outputs infrared rays, it is of course possible to adopt a configuration that outputs other electromagnetic wave signals such as visible light.

〔Effect of the invention〕

As explained above, according to the present invention, the second electromagnetic wave signal output means is provided which compares the count time and the reserved time and outputs the set electromagnetic wave signal when the count time reaches the reserved time, By making appropriate settings using the reserved time setting means, it is possible to automatically output the set electromagnetic wave signal set by the electromagnetic wave signal setting means at a desired time, thereby expanding the range of applications of the remote control. be able to.
