Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to a remote control device used for remote control of, for example, video equipment, audio equipment, or air conditioners.

(Prior Art) As a conventional remote control device for video equipment, etc., there is, for example, one using a remote commander. The remote commander is equipped with control keys such as a power operation key, a channel selection key, and a volume key, and by pressing the control keys, an infrared control signal is wirelessly transmitted to the controlled device such as the video device. and perform the necessary control operations.

However, this method using infrared control signals from the remote commander is a one-way control from the remote commander, and no feedback signal indicating execution of the control operation is obtained. Whether or not a required control operation has been executed is left to the operator's visual inspection or the like. For this reason, it is difficult to confirm whether or not the control operation is being performed normally, which may result in malfunctions. Further, since the control contents are limited to the control keys provided on the remote commander, it is difficult to change the control contents when desired.

In addition, as another conventional remote control device, as shown in FIG.
The infrared receiver @3 is placed at an appropriate interval so as to face the
There is one with 3 placed on it. Then, a control signal from a personal computer or the like is transmitted to the infrared converter 33 via the cable 34, and the infrared control signal is received by the infrared receiver 32, and the required control operation is performed on the controlled am device 31. .

In this conventional example, since a personal computer or the like is used as the source of the control signal, it is relatively easy to change the control contents. However, in this conventional example, the infrared converter 33 is disposed in front of the infrared receiver 32 facing the infrared receiver 32 at an appropriate interval.
3 becomes difficult, and as in the conventional example described above, it is difficult to devise a means for obtaining a feedback signal, and it is sometimes difficult to confirm whether the control operation is being performed normally. Further, a space for arranging the infrared converter 33, which is a relatively large object, is required at a position in front of the controlled device 31, which makes it inconvenient to install the infrared converter 33.

(Problem to be Solved by the Invention) In both of the above conventional examples, there is no means for obtaining a feedback signal indicating the execution of the control operation, so it is difficult to confirm the normal execution of the control operation, and malfunctions occur. There was a problem in that there were cases where this was done. In addition, with the conventional remote commander, it is difficult to change the control content, whereas with the infrared converter, the infrared converter is a relatively large object. Since they were placed in front of the controlled equipment at appropriate intervals, there was a problem in that they were inconvenient to handle.

The present invention has been made based on the above circumstances, and it is possible to obtain a feedback signal indicating the execution of a control operation to cause a controlled device to accurately perform a normal control operation, and,
It is an object of the present invention to provide a remote control device that is easy to change control contents and is convenient to handle.

[Structure of the Invention] (Means for Solving the Problems) In order to solve the above-mentioned problems, the present invention includes a first light receiver that receives a control optical signal; A remote control device connected to a side of a controlled device, which is equipped with an indicator that emits light to indicate that a required operation has been executed in response to a control signal, and includes a control section that sends out a control signal, and one common contact. , a jack that is provided with a first contact and a second contact and is connected to the control unit; and a jack that is installed opposite to the first light receiver and that connects the common contact of the jack with the first contact using two cables. a light emitting device connected to the contact and configured to convert a control signal from the control unit into light and emit the control signal; and a light emitting device installed opposite to the display and connected to the common contact side of the two cables. a second light receiver that uses a shared cable as a shared cable and is connected to the jack by a cable connected to the shared cable and the second contact, and inputs a signal obtained by photoelectrically converting the operation display light of the display to the control unit; The gist is to have the following.

(Function) The control signal sent from the control unit is transmitted through the cable to the controlled 11
When you want to change the control content as it is transmitted to the device,
This is easy to deal with. Further, the light emitter and the second light receiver in the remote control device are installed facing the first light receiver and the display device on the controlled device side, respectively, and are connected to the light receiver and the second light receiver. The other end of the cable has a common contact and a first and second contact.
It is convenient to handle because it is plugged into the control unit using a contact type jack.

When executing the control, a control optical signal from the light emitter is received by the first light receiver, and the photoelectrically converted control signal causes the controlled device to perform a required control operation. Next, the execution of the required operation is indicated by light emission on the display, and this operation display light is photoelectrically converted by the second light receiver and fed back to the control section. The execution of the control operation is then confirmed by the control unit, and the controlled device performs the normal control operation accurately.

゛(Example) Hereinafter, an example of the present invention will be described based on FIGS. 1 to 9. This embodiment is applied to an infrared (hereinafter also referred to as IR) type remote control device.

First, let me explain the configuration of the remote control device.
In FIG. 1, reference numeral 1 denotes a control unit that sends control signals, and the control unit 1 includes a microcomputer unit 2, an operation input unit 3, a memory unit 4 that stores control programs, etc., an IR destination control unit 5, and a light receiving signal. A detection section 6 is provided.

7 is a light emitter using an LED for IR emission; 8 is a light receiver (second light receiver) using a phototransistor;
As shown in the figure, the light emitter 7 is attached so as to face the IRR light device (first light receiver) 11 in the controlled device 9 such as video equipment, and the light receiver 8 is also connected to the controlled device 9. It is attached so as to face the display device 12 for display. Since the anode of the LED in the light emitter 7 and the collector of the light receiver 8 use the same potential, the power cable 13 connected to the anode and the power cable 14 connected to the collector are connected to one common cable 15.
3 using the mini jack for stereo headphones.
Common contact (outer contact) 1 in contact type jack 16
7 is connected. Further, the cathode cable 20 connected to the cathode of the LED in the light emitter 7 is connected to the first contact (intermediate contact) 18 in the jack 16,
Emitter cable 21 connected to the emitter of light receiver 8
is connected to a second contact (inside contact) 19 in the jack 16.

In this way, the emitter 7 and the receiver 8 are connected to the jack 16 with a total of three cables 15, 20, 21,
As shown in Figure 3, these cables 15.20,2
1 is bundled into one for convenient handling. Then, by inserting the jack 16 into the plug 22 on the control section 1 side, the light emitter 7 and the light receiver 8 are connected to the control section 1.

4 to 7 are enlarged views of the structure of the light emitting device 7, in which a printed circuit board 25 is fitted into an envelope consisting of a case 23 and a lid 24, and the soldering on this printed circuit board 25 is shown in FIG. The terminals of the LED 27 are soldered to the pattern 26. As shown in FIG. 7, the LED 27 has its light emitting surface facing downward in the figure. 28 is an IR filter,
29 is an adhesive film, and with this adhesive film 29,
As described above, it is attached so as to face the IRR optical device 11.

The structure of the light receiver 8 is also substantially similar to the structure of the light emitter 7 described above.

Next, a control method will be described using FIGS. 8 and 9, taking as an example a sequence for turning on the power of the controlled IT device 9.

The control signal sent from the control unit 1 is a combination signal of pulse width, period, pulse code, etc., as shown in FIG. 8(a) (partial enlarged view of FIG. 8(b)) It is configured.

First, when an appropriate operation command is given to the microcomputer section 2 from the operation input section 3, the microcomputer section 2, according to the command, turns on the power to the controlled m+ equipment 9 using the signal from the light reception signal detection section 6. Check to see if there is one.

If the power is off, the power-on IRR signal format is retrieved from the memory unit 4, the IRR light control unit 5 sends a power-on command signal to the light emitter 7, and other IR signals for control are sent. The signal is sent to the IRR optical device 11 to give a power-on command to the controlled device 9 (FIG. 9(a)).

When the power to the controlled device 9 is turned on in response to this command, the display 12 emits light to indicate that the power has been turned on (FIG. 9(b)). As a result, the receiver 8
The light receiving current i flows (FIG. 9(C)), and the feedback signal "1" indicating that the power is turned on is extracted from the light receiving signal detecting section 6 in the control section 1 (FIG. 9(d)).
), the control unit 1 performs the detection operation of this feedback signal. This detection operation is performed by entering this detection mode immediately after sending the command signal and checking for a certain period of time.

When the aforementioned feedback signal is detected within this certain period of time, the control operation is confirmed and the sequence ends. At this time, if a feedback signal is not obtained within a certain period of time for some reason, the sequence will not end and the non-confirmation process will continue. In this way, the controlled device 9 is accurately controlled in accordance with the command signal.

In addition, when it is desired to change the control contents of such control commands for the controlled device 9, possible command formats are stored in the memory section 4 in advance, and this can be used as commands from the operation input section 3. You can respond appropriately by withdrawing the information.

[Effects of the Invention] As explained above, according to the present invention, the display unit emits light to indicate that the required control operation has been performed on the controlled device, and this operation display light is photoelectrically converted by the second light receiver. Since the control unit confirms the execution of the control operation and is fed back to the control unit, the control unit can confirm the execution of the control operation and accurately perform the normal control operation. Further, since the control signal sent from the control section is transmitted to the controlled device via a cable, it becomes easy to change the control contents. Furthermore, a light emitter and a second light receiver in the remote control device are mounted to face the first light receiver and a display device on the controlled device side, respectively, and are connected to the light emitter and the second light receiver. The other end of the cable has a common contact and the first and second
It has the advantage of being convenient to handle, since it is plugged into the control unit using a three-contact jack with three contacts.
