Abstract

PURPOSE:To control plural equipments to be controlled to which different identi fication codes are assigned by remote-controlling the equipments to be controlled by converting the identification codes when an equipment controlling data code is detected. CONSTITUTION:When the control key of a CD changer 22 is operated from a remote control 19, a data code and identification code 'A' corresponding to the key are generated and a remote control signals produced by synthesizing both of the codes is transmitted to a receiver 21 from a transmitting section 27. The detected signal of a receiving section 28 is stored in a memory 30 and a deciding means 31 switches a switch 32 in accordance with the code 'A'. Another deciding means 33 detects a data code for control. Accordingly, a converting means 34 is actuated and converts the identification code 'A' in the memory 30 into another identification code 'B' and the code 'B' is supplied to the CD changer 22 together with the data code. When a discriminat ed means 38 detects the code 'B', the data code is converted into a control signal by means of an arithmetic means 39 and the compact disk is changed through an interface 40.

Next, the operation of the above embodiment will be explained. First, remote control using the remote control 19, which also serves as a radio and a CD changer, will be explained. When one of the keys provided on the remote controller 1 is operated to control the radio receiver 21, for example, a key for changing the reception frequency, the data code generating means 24 generates a data code corresponding to the operated key. An identification code "A" is generated from the identification code generating means 25, the two codes are combined by the calculating means 26, and a remote control signal is transmitted from the transmitting section 27. This remote control signal is detected by the receiving section 28 of the radio receiver 21 and stored in the memory means 30. The identification code determination means 31 determines whether the identification code held in the memory means 30 is "
A'' is detected, so the changeover switch 32 is switched as shown by the broken line.Furthermore, the data code determination means 33 determines that the data code held in the memory means 30 is a data code for controlling the radio receiver. This data code is input to the calculation means 35 to generate a control signal for changing the receiving frequency of the radio receiver, and this control signal is sent to the receiving frequency changing means (not shown) via the interface 36. ), and the reception frequency of the radio receiver is changed. When the above processing is completed, the changeover switch 32 returns to the connected state shown by the solid line.

Next, the operation of remotely controlling the CD changer 22 using the remote control 19 will be explained. When one of the keys on the remote control 19 is operated to control the CD changer 22, such as a key to change from the currently played compact disc to another compact disc, the data code and identification corresponding to this operation key are displayed. Code "A" is generated, and a remote control signal that is a combination of both codes is sent to the transmitter 2.
It is transmitted from 7. This remote control signal is transmitted to the radio receiver 2
1 is detected by the receiving unit 28 and stored in the memory means 30. The identification code determining means 31 detects that the identification code held in the memory means 30 is "A" and switches the changeover switch 32 from the connected state shown by the solid line to the connected state shown by the broken line. Further, the data code determining means 33 detects that the data code held in the memory means 30 is a data code for controlling a CD changer.

Therefore, the code conversion means 34 operates, and the memory means 30
The identification code "A" held in the identification code "B"
At the same time, this code-converted identification code 'B'' and the CD held in the memory means 30 are
The changer control data code is transmitted to the other input terminal of the changeover switch 32. In this case, since the changeover switch 32 is switched to the connection state shown by the broken line, the identification code "Bo" output from the code conversion means 34 is
and the data code are input to the CD changer 22 via the changeover switch 32. The identification code determination means 38 of the CD changer 22 determines that the input identification code is "B".
In order to detect that ilJ i
A signal is transmitted via the interface 40 to a controller (not shown) for changing the compact disc, and an operation for changing the compact disc is performed. When the above series of processes is completed, the changeover switch 32 returns to the state shown by the solid line.

Next, use the remote control 19b dedicated to the CD changer to
The operation of remotely controlling the D Change-22 will be explained. One of the keys provided on the remote control 19b,
For example, when you operate a key to end playback of a CD,
At the same time as the data code corresponding to this 10- is generated, an identification code "B" is generated, and a remote control signal consisting of both codes is transmitted from the infrared light emitting diode 27b. This remote control signal is received by the receiving section 28 of the radio receiver 21 and input to the CD changer 22 via the changeover switch 32 which is in the switching state shown by the solid line. The identification code determination means 38 transmits the input data code to the calculation means 39 in order to detect that the input identification code is "B". Arithmetic means 39 generates a control signal according to the data code. This control signal is transmitted via the interface 40 to a control section (not shown) that stops playing the compact disc, and the playing operation of the compact disc is stopped.

In this example, CDs to which identification code °B'' is assigned
The changer 22 and the remote control 19b dedicated to this CD changer 22 have already been commercialized, and this is effective when commercializing a composite audio device that combines this CD changer 22 and a radio receiver. That is, in such a case, the identification code "B" cannot be assigned to a newly commercialized radio receiver in order to prevent malfunction, but another identification code "A" must be assigned. In this way, according to this embodiment, even if the remote controller 19 generates one type of identification code "A", different identification codes "A" and "B" are assigned to him, i! l N equipment 21
and 22 can be remotely controlled, and the CD changer 22 can also be remotely controlled with a remote control 19b dedicated to the CD changer.

The above embodiment is an example in which a radio receiver and a CD changer are remotely controlled. The R control equipment is not limited to these, and the present invention can be applied to two or more controlled equipment.

Effects of the Invention The present invention has the above configuration and has the advantage that a plurality of controlled devices having different assigned identification codes can be remotely controlled by a remote control signal transmitting device that generates one type of identification code. Therefore, the configuration of the remote control signal transmitting device can be simplified.
