Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic device identification code setting method for setting an identification code of an electronic device such as a compact disc changer.

[0002]

2. Description of the Related Art FIG. 6 shows a plurality of compact disks (C
D) A block diagram showing an outline of a conventional CD changer system for controlling a changer. In FIG.
1, 2 and 3 are CD changer devices, and 4 is a controller for controlling the CD changer devices 1, 2 and 3.

As shown in FIG. 6, when a plurality of CD changer devices are connected to the controller 4 to reproduce a CD, it is necessary to set an identification code (address) for identifying each CD changer device in each CD changer. There is. FIG. 7 shows an address setting unit provided on the back surface of the device body 5 of the CD changer device. This address setting section is composed of three DIP switches 12, 13, and 14, and an address for identifying the CD changer device is set by a combination of ON / OFF of the DIP switches 12, 13, 14. Controller 4 is each C
It identifies the address set in the D changer device and sends a reproduction command to a desired CD changer device.

[0004]

However, in the above-mentioned conventional example, a plurality of DIP switches 12 for setting the identification code (address) of each CD changer device,
There was a problem that 13 and 14 had to be provided.

The present invention solves the above-mentioned problems of the prior art, and utilizes the operation button provided in the electronic device without providing a separate component for setting an identification code such as a DIP switch. It is an object of the present invention to provide an identification code setting method for an electronic device that can more easily set an identification code.

[0006]

In order to achieve the above-mentioned object, the present invention has an operating means for giving an operation command to the equipment body, and the operation of the operating means is based on the operation time by this operation means. Is determined to be an operation command to the operation code or the identification code setting mode, and when it is determined to be the identification code setting mode, the identification code corresponding to the number of operations of the operating means is stored in the memory. .

Therefore, according to the present invention, when the operating means is operated for a short period of time, it is determined that the operation command is to the device body, and the original operation of the device body is performed. On the other hand, when the operating means is operated for a long time, the identification code setting mode is entered, and the data based on the number of times the operating means is operated can be stored in the memory as the identification code. The identification code can be easily set by using it.

BEST MODE FOR CARRYING OUT THE INVENTION

(Embodiment 1) An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the structure of a CD changer device according to this embodiment, and FIG.
The CD magazine used for a changer apparatus is shown. In FIG. 1, reference numeral 5 denotes a device body, and an insertion port 7 into which the CD magazine 6 shown in FIG. 2 is inserted is formed on the front surface of the device body 5. 8 is C inserted in the insertion slot 7
This is an eject button for ejecting the D magazine 6.

In FIG. 2, reference numeral 9 denotes a magazine case having an opening on one side, and a plurality of trays 10 are slidably accommodated in the magazine case 9. 11 is tray 10
The CD is placed in the recess 11. In the device body 5 of the CD changer device shown in FIG. 1, a disc player that reads data from the CD while rotating the CD, and a tray pull-out mechanism that inserts and removes a predetermined tray 10 in the inserted CD magazine 6 from the magazine case 9 , A CD loading mechanism for transferring a CD placed on the tray 10 that has been pulled out to a turntable of a disc player or for returning a CD placed on the turntable to the tray 10, a CD magazine 6 inserted in the insertion slot 7. The eject mechanism for ejecting is stored.

FIG. 3 shows a C using a CD changer device.
It is a block diagram of a D changer system. Also in this embodiment, as in the conventional example, the controller 4 and each C
The D changer devices 1, 2 and 3 are connected by a bus. The feature of the present embodiment is that the eject button 8 provided in the CD changer devices 1, 2, 3 is used to set the identification code (address) of each CD changer device 1, 2, 3.

FIG. 4 is a schematic block diagram of the identification code setting section of the CD changer device. In FIG.
Reference numeral 8 is an eject button, and when the eject button 8 is pressed, a switch (not shown) is turned on. A switch on / off signal generated by operating the eject button 8 is input to the microcomputer 15 of the changer control circuit in the device body. The microcomputer 15 determines from the on / off signal whether it is the original CD magazine eject command or the identification code (address) setting mode. When the identification code setting mode is determined, the eject button 8 is pressed.
The identification code input by the above operation is stored in the memory 16.

FIG. 5 shows the operation timing of the eject button 8 in the above embodiment. As shown in FIG. 5 (A), when the eject button 8 is pressed for less than a predetermined time (t), the microcomputer 15 determines that it is a CD magazine eject command, and ejects the CD magazine 6 from the device body 5. The mechanism is activated to eject the CD magazine 6.

On the other hand, as shown in FIG. 5B, when the eject button 8 is pressed for longer than a predetermined time (t), the microcomputer 15 determines that it is in the identification code setting mode. As shown in FIG. 5 (C), after the eject button 8 is pressed for longer than a predetermined time (t) to enter the identification code setting mode, the eject button is pressed a predetermined number of times to input the identification code. After the identification code is input, the eject button 8 is pushed for longer than a predetermined time (t) to cancel the identification code setting mode. As shown in FIG. 5C, the number of times the eject button 8 is pressed is determined as an identification code, and this identification code is stored in the memory 16 in the device body 5.

Each CD changer device 1 in FIG.
The controller 4 can identify each CD changer device by reading the identification code set by the operation of the eject buttons 8 of 2 and 3 and stored in the memory 16 on the controller 4 side.

As described above, according to the above-described embodiment, it is possible to install the CD without the DIP switch as in the conventional example.
By using the eject button 8 for commanding the operation of the changer device, there is an advantage that the identification code can be set.

Although the above embodiment is an example of the CD changer device, the present invention is not limited to the CD changer device but can be applied to other disc changer devices such as electronic devices which need to set an identification code.

[0017]

As is apparent from the above-described embodiment, the present invention utilizes the operating means originally provided for the operation command without providing a separate component for setting the identification code such as the DIP switch. By doing so, there is an advantage that the identification code of the electronic device can be easily set.
