Many karaoke shops are equipped with a number of search-type karaoke selection remotes, which is why a set of cradles is available. Collective cradles are designed to accommodate multiple remote controls in one cradle.

As a typical example, a cradle is connected to an RS-232C communication terminal of a karaoke apparatus, and a searchable karaoke selection remote controller mounted on the cradle and the karaoke apparatus communicate with each other to transmit update data from the karaoke apparatus to the remote controller. The communication speed is relatively low at 9600 bps. Therefore, if one of a large number of search-type karaoke selection remote controllers transmits the update data from the karaoke apparatus in order, there is a problem that the karaoke apparatus is bound for a long time for the processing, which is not practical.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and an object thereof is to efficiently and reliably be provided by the karaoke apparatus via a cradle via a process of updating a music database of a plurality of searchable karaoke music selection remote controllers. The present invention aims to provide a collective cradle of searchable karaoke music selection remote controllers that can be realized in a high structure.

In addition, the collective cradle according to the second invention includes a plurality of remote controller connection connectors for respectively connecting a searchable karaoke music tune remote controller, a source connection connector for connecting to a data transmission destination such as a karaoke device or another collective cradle, and each remote controller. A switching circuit connected to the connection connector and the source connection connector by internal wiring, respectively, and a marking means for recognizing it with respect to the searchable karaoke music selection remote control connected to the specific one remote control connection connector; The switching control is performed by the switching control signal supplied from the outside to the remote control connecting connector, so as to selectively connect one specific remote control connecting connector with one of the other remote control connecting connector and the source connecting connector.

The configuration of one embodiment of the collective cradle according to the first invention is shown in FIG. 1, and the use situation thereof is shown in FIG. Cradle 1 of this example has three slots (first slot S1, second slot S2, third slot S3), one for each slot S1, S2, S3 in total. A large search type karaoke music selection remote control 2 can be attached. Remote slot connecting connectors C1, C2, and C3 are disposed in the slots S1, S2, and S3, respectively.

The karaoke apparatus 3 is basically a transmission destination of the update data of the music index database, but as shown in FIG. 2, an updated search karaoke selection remote control unit 2 is installed in the first slot C1. The type cradle 1 can also be a destination of update data.

In order to connect with the transmission destination of the update data, the source cradle 1 is provided with a source connection connector C4. In addition, a target connection connector C5 is disposed in the collective cradle 1 in order to connect with another collective cradle 1 that is the destination of update data.

The data communication performed through these connectors C1 to C5 is bidirectional communication based on the serial interface standard of RS-232C.

Each connector C1 to C5 is connected to the switching circuit 4 by internal wiring (data communication wiring), respectively. In addition, a buffer amplifier that performs voltage conversion and waveform shaping during the wiring for connecting the source connection connector C4 and the switching circuit 4 and the wiring for connecting the target connection connector C5 and the switching circuit 4 thereto ( 6) is interposed.

In the switching circuit 4, each terminal to which each connector C1-C5 is wired is set as the port P1-P5, respectively. The switching circuit 4 operates according to the switching control signal applied to the control port Pcont from the signal line 5 connected to the remote controller connecting connector C1 of the first slot S1, and the first slot S1. The circuit P is configured to selectively connect the port P1 connected to the remote controller connecting connector C1 to any one of the other four ports P2 to P5.

The remote control connector C1, C2, C3 has a pin corresponding to the signal line 5 of the connector C1 in addition to the pin to which the internal wiring for data communication leading to the switching circuit 4 is connected, and the cradle 1. Charging circuit pins for supplying the output of the built-in charging circuit (not shown) to the remote controller 2, and to the remote controller 2 itself which slots S1, S2, and S3 are mounted in the remote controller 2 Marker code pins and the like are included.

Marker pins are present in each of the two remote control connector connectors C1, C2 and C3. As shown in Fig. 3, both of the two symbol code pins in the connector C1 of the first slot S1, which are described as the one &quot; specific one remote control connector, &quot; . The two marked code pins of each of the second slot S2 and the third slot S3 are connected to one ground and the other open.

As shown in Fig. 3, the internal circuit on the side of the remote control unit 2 connected to each of the remote control connecting connectors C1, C2, and C3 connects two lines corresponding to two marker code pins to a power supply through a pull-up resistor. The central processing unit (microcomputer) of the remote controller 2 reads the voltage level (logical level) of the two lines (called the marker reading line).

Therefore, the marker read line at the remote controller 2 connected to the connector C1 of the first slot S1 represents a two-bit logic signal "00". In addition, the marker reading line in the remote controller 2 connected to the connector C2 of the second slot S2 and the connector C3 of the third slot S3 represents a two-bit logical code "10". In addition, the marker reading line in the remote controller 2 which is not mounted in any slot will show the logical code "11" of two bits.

By this marking means, the built-in computer of the search-type karaoke selection remote control 2 can recognize whether the remote control itself is mounted in the slot of the collective cradle 1, and at the same time, the mounting position when it is mounted in the slot. Is configured to recognize whether is the first slot (S1).

The search-type karaoke selection remote control 2 mounted in the first slot S1 recognizes it and operates as shown in the schematic flowchart of FIG. 4 (this remote control is also called a parent remote control). The searchable karaoke music selection remote control 2 mounted in the second slot S2 or the third slot S3 recognizes it and operates as shown in the schematic flowchart of FIG. 5 (this remote control is also called a child remote control). .

The parent remote controller 2 gives a signal to the control port Pcont of the switching circuit 4 and first connects the port P1 to the port P4. In this way, the connector C1 to which the parent remote controller 2 is connected and the source connection connector C4 are connected. Here, as in the use example A shown in FIG. 2, it is assumed that the karaoke apparatus 3 is connected to the source connection connector C4. The parent remote control unit 2 communicates with the karaoke apparatus 3, receives the release number of the music index database, and compares it with the release number of the music index database held by the parent remote control unit 2 to perform database update processing. Determine whether there is a need. When performing the database update process, the parent remote control unit 2 communicates with the karaoke apparatus 3, receives the update data, and executes the necessary process.

Subsequently, the parent remote controller 2 switches the switching circuit 4 to connect the port P1 to the port P5. Thereby, the connector C1 to which the parent remote control 2 is connected, and the target connection connector C5 are connected. In the use example A shown in FIG. 2, nothing is connected to the target connection connector C5. In the use examples (B) and (C), the target connection connector C5 of the first cradle is connected to the source connection connector C4 of the second cradle.

The parent remote control 2 attempts communication via the target connection connector C5 to check whether there is a response. In use examples (B) and (C), the parent remote control 2 (called the first parent remote control) of the first cradle detects a response from the parent remote control 2 (called the second parent remote control) of the second cradle. Done. In this case, the first parent remote controller finds the release number of the database held by the second parent remote controller, and compares it with the release number held by the first parent remote controller. Update data is transmitted from the remote control to the second parent remote control. The second parent remote controller updates the database according to the received update data.

Subsequently, the parent remote controller 2 switches the switching circuit 4 to connect the port P1 to the port P2. Thereby, the connector C1 to which the parent remote control 2 is connected, and the connector C2 which may be connected to the child remote control are connected. The parent remote control 2 attempts communication via the connector C2 to check whether there is a response. If the child remote control 2 is connected to the connector C2, the response is found, so the release number is found from the child remote control 2, and if it is old, the update data is transmitted from the parent remote control to the child remote control, and the child remote control is connected. Receives it and updates the database.

Subsequently, the parent remote controller 2 switches the switching circuit 4 to connect the port P1 to the port P3. Thereby, the connector C1 to which the parent remote control 2 is connected, and the connector C3 which may be connected to the child remote control are connected. The parent remote control 2 attempts communication via the connector C3 to check whether there is a response. If the child remote control 2 is connected to the connector C3, because it responds, it finds the release number from the child remote control 2, and if it is old, transmits update data from the parent remote control to the child remote control, and the child remote control does it. Receive and update the database.

The collective cradle according to the present invention has only a plurality of connectors and a switching circuit for performing connection switching between the connectors as a configuration related to the data communication function, and can be mass produced at a very low cost with a very simple configuration. A searchable karaoke music selection remote control connected to one specific connector of such a collective cradle becomes the subject controlling the switching circuit, and the remote control is led by a remote control and transmits data such as a remote control mounted on a karaoke device or another cradle. By performing data communication between data receivers such as another remote controller mounted on the cradle or a remote controller mounted on the other cradle, the music index database held by the plurality of remote controllers can be efficiently updated. The reliability of the update process is also increased.
