BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic turntable which can be remotely operated using a remote controller.

[0002]

2. Description of the Related Art In recent years, television receivers have become widespread. In this television receiver, the impression of the projected image differs depending on the viewing angle of the screen. Therefore, it is desirable to view the image from the front as much as possible. However, depending on the arrangement position of the television receiver, the screen becomes difficult to see due to external sunlight or other light, and the viewing position of the user (viewer) is not always fixed. There is a demand from users for changing the television screen of the television receiver in an arbitrary direction. Therefore, conventionally, there has been a television receiver having a configuration in which the television receiver body is rotatably mounted on a pedestal by driving means such as a motor. A remote control attached to such a television receiver is provided with a rotation key for driving a motor. When a user wants to rotate the television receiver, pressing the rotation key causes the television receiver main body to rotate. Can be rotated in a desired direction. In such a television receiver, the television screen can be arbitrarily rotated by remote control, so that the user can turn the television screen in the best direction while staying at that position.

[0003]

If the television receiver is provided with a rotation function in advance as described above, the television screen of the television receiver can be rotated in any direction. Most receivers do not have the rotation function described above. Therefore, if the user wants to provide the above-described rotation function to the television receiver, the only option is to purchase a television receiver with a rotation function.

Accordingly, the present invention has been made in view of the above points, and has as its object to provide an automatic turntable for adding a rotation function to a television receiver having no rotation function.

[0005]

SUMMARY OF THE INVENTION The present invention, as a means for achieving the above object, comprises a fixed portion and a rotating portion rotatably mounted on the fixed portion, which is attached to a television receiver. Operating the channel key of the remote controller, the automatic rotating table to rotate the rotating unit in a desired direction,
By operating a channel key of the remote controller, receiving a transmission signal output from the remote controller, and outputting a reception signal according to the reception result; and a channel code different for each remote controller as the reception signal. A plurality of storage means, and a detection means for detecting whether a reception signal output from the reception means is a reception signal of a channel code stored in the storage means, and detecting whether the reception signal is a channel stored in the storage means. It is an object of the present invention to provide an automatic rotating table, comprising: control means for outputting a drive signal for rotating the rotating portion when the code is continuous for a predetermined period or more.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, most of widely used television receivers do not have a rotation function, and therefore, an automatic turntable that can be rotated with the television receiver mounted thereon is used as a television receiver. We decided to provide it separately. Here, if the rotation operation is a manual operation, it is difficult to rotate the television screen in the best direction. Therefore, it is desirable to adopt a configuration in which remote control using a remote control is possible. But,
Providing a dedicated remote control on an automatic rotating base that performs a simple operation not only increases the cost but also increases the number of remote controls in addition to the television receiver, which makes the usability worse. Therefore, the present inventor paid attention to the fact that an existing remote control, particularly in recent years, a dedicated remote control is attached to most TV receivers, and drives the automatic turntable using the remote control for this TV receiver. I thought about letting it. However, since the television receiver is also operating at the time of operation of the automatic turntable, if the automatic turntable is rotated using the remote control for the television receiver, the television receiver also operates. The problem occurs.

[0007] Therefore, the present inventor has made the automatic turntable to be driven when a key which does not greatly affect the current operation state of the existing apparatus is used in a state other than a normal use state. That is, even if the television receiver is operating,
The system is configured to operate by continuously pressing a remote control key that does not significantly affect the current operation (for example, the channel currently being viewed does not change), for a predetermined period or more. One of such remote control keys is a direct channel key (a key provided to directly select a channel, and may be simply referred to as a channel key hereinafter). The direct channel key is provided on a dedicated remote controller of most existing television receivers, and when a user attempts to change the channel, the time for pressing the channel key is almost instantaneous in many cases. Therefore, even if the key of the channel currently being received is kept pressed, there is no great hindrance in viewing.

An embodiment of the present invention will be described below with reference to the accompanying drawings. FIG. 1 is an external view of an automatic rotating table according to an embodiment of the present invention, and FIG. 2 is a block diagram showing a configuration of a main part thereof. As shown in FIG.
Has a rotating unit 3 rotatably mounted on a main body 2 as a fixed unit. The upper surface of the rotating unit 3 is flat, and the television receiver 4 is placed on the rotating unit 3 (see FIG. 1B). The remote controller 5 of the television receiver 4 is provided with a key 5A for operating the television receiver 4 as shown in FIG. 2B, and by pressing a predetermined key corresponding to a desired operation. The television receiver 4 operates. Further, on the front of the main body 2 of the automatic turntable 1, a receiving section 11A of a receiving means 11 for receiving a transmission signal transmitted from a remote controller 5 attached to the television receiver 4 is provided. Here, most of the remote controllers attached to currently marketed television receivers are infrared remote controllers. Therefore, the receiving unit 11A includes a light receiving element (not shown) such as a photodiode for receiving infrared rays. The light receiving element is mounted in a light receiving window 11B provided on the front of the main body 2.

Further, the main part of the automatic turntable 1 is configured as schematically shown in FIG. According to the figure, the automatic turntable 1 receives a transmission signal from the remote controller 5 by using the reception unit 11A and outputs a reception signal 21 corresponding to the reception signal. Control means 12 for outputting a drive signal 22 in response to the received signal 21 received; and drive means 13 for rotating the rotating section 3 in response to the drive signal 22 output from the control means 12.
And a storage unit 14 in which an operation program of the control unit 12 and various information of the transmission signal are stored. The light receiving unit 11 includes an amplifier circuit for amplifying a signal received by the light receiving unit 11A, a waveform shaping circuit for shaping a waveform, and the like. The control means 1
Reference numeral 2 denotes a microcomputer, and the storage means 14
To execute the operation program stored therein. The operation of the automatic turntable 1 based on this operation program will be described later. The driving means 13 includes a motor serving as a driving source for rotating the rotating section 3, a motor driver for driving the motor, and the like.
The rotating unit 3 is rotated in a predetermined direction on the basis of.

The storage device 14 temporarily stores a ROM (Read Only Memory) storing the operation program and a plurality of transmission signals different for each remote controller 5, and a channel code detected by the receiving means 11. Or ROM
RAM (Random) that stores transmission signals not stored in
Access Memory). Here, the transmission signal from the remote controller 5 usually includes a function code indicating a function such as channel selection or volume adjustment. However, the format or code notation of the transmission signal is different for each remote controller 5 (for example, Since the information is different for each manufacturer, information on all of them is stored in the storage means 14. In this embodiment, since the operation is performed by pressing the channel key of the remote controller 5, all the channel codes for each remote controller 5 are stored. Here, the automatic turntable 1 according to the present embodiment stores all the channel codes that are different for each remote controller 5 as described above. It is difficult to identify whether the code is a code or not, and the automatic turntable 1 may malfunction.
Therefore, the automatic turntable 1 according to the present embodiment performs an initial setting for specifying the remote controller 5 before performing the operation. Although a detailed description of this initial setting is omitted here, for example, the remote controller 5 may output a predetermined transmission signal from the remote controller 5 and detect the signal to identify the remote controller 5 or automatically rotate the remote controller 5. An operation button for initial setting may be provided on the base 1, and the remote control 5 may be specified by operating the button. After the initialization is performed, the operation described below is performed.

Next, the operation of the automatic turntable 1 will be described with reference to the flowchart shown in FIG. When the power of the automatic turntable 1 is turned on, the control unit 12 controls the receiving unit 1.
It is in a state of detecting whether there is an output of the reception signal 21 from 1 (step 101). That is, it is in a state where it is detected whether or not a transmission signal is output from the remote controller 5. If it is detected that any transmission signal is output from the remote controller 5, the reception means 11 responds to the reception signal 21. Is output, and when the control means 12 detects the received signal 21, the process proceeds to the next step 102.

In the next step 102, the received signal 2
It is determined whether 1 is a channel code (102).
The control unit 12 refers to the channel code of each remote control device 5 stored in the storage device 14 and compares the channel code with the detected reception signal 21. As a result of the comparison, if the received signal 21 is not a channel code, the step 10
Return to 1. If the received signal 21 is a channel code, a timer (not shown) is operated (step 10).
3) The code detected by the received signal 21 is stored in the RAM of the storage means 14 (step 104), and the process proceeds to the next step 105.

In the next step 105, the channel code detected in the received signal 21 is kept for a certain period (for example, 2 seconds).
It is detected whether the data is continuously received (step 10).
5). The measurement of the reception time is performed by the timer. When the reception signal 21 is not input within a certain period of time, or when a code different from the code stored in the storage means 14 (when a different channel key is pressed) is input, The operating timer is stopped and reset (step 106), and the storage unit 14 is stopped.
Is reset (step 107), and the process returns to step 101. Here, if a different channel key is pressed, the process proceeds from step 101 to step 105 through steps 102, 103 and 104. In step 105, the newly transmitted channel code is It is detected whether the data is continuously transmitted.

If it is detected in step 105 that the channel code has been continuously received for a predetermined period or more, the control means 12 outputs the drive signal 22 (step 108). When the drive signal 22 is output, the drive unit 1
At 3, the rotating unit 3 is rotated by a driving mechanism such as a motor (not shown). Rotating part 3 by this driving means 13
Is rotated to the left, for example, and then to the right when rotated by a certain angle. The control means 12 continues to output the drive signal 22 while the same code as the code stored in the storage means 14 is continuously detected (step 109). Then, when the code is not detected anymore, through the above-described step 106 (timer reset) and step 107 (memory reset),
The process returns to step 101.

By performing the above operations, the user can keep pressing the channel key of the remote controller 5 for a certain period of time or more.
Rotates, and the rotation stops when the button is released, so that the user can rotate the television receiver 4 in a desired direction by holding down the channel key of the currently watching channel.
Also, code information of a key such as a volume key that may be kept pressed for a certain period of time or more when operating the television receiver is not stored in the storage unit 14. Therefore, when such a key is pressed, the rotation of the rotating unit 3 is prevented from being performed by the determination in the above step 102, and the malfunction of the automatic turntable 1 is prevented. .

By the way, the automatic turntable 1 can perform other operations by appropriately changing an operation program for operating the control means 12 and contents stored in the storage means 14. For example, when the same channel is pressed twice from the remote controller 5 toward the automatic rotating table 1 within a predetermined period, the rotating unit 3 is driven, and then the same channel key, volume adjustment key, etc. The rotation operation may be stopped when the key is pressed. in this case,
A light emitting device such as an LED which is turned on when a channel key is pressed is provided. When the automatic turntable 1 receives a channel code, the light emitting device is turned on.
Each time the same channel code is received, the rotation of the rotating unit 3 is started. Then, while the rotating unit 3 is rotating, the rotation of the rotating unit 3 is stopped by pressing the appropriate key. Further, the light emitting device is configured to be turned off after the certain period has passed. Further, in the above-described embodiment, the rotating unit 3 is configured to rotate in the predetermined direction at first, and then rotate in the opposite direction at a certain angle, so that the television receiver 4 is rotated in the desired direction. May take some time. Therefore, the key pressing method may be changed, or a key that does not change the current operation state other than the channel key (for example, a key for displaying the current reception channel) may be used in combination with the channel key. Some recent remote controls for video decks can operate a television receiver, but many remote controls do not have a direct channel key. In such a remote controller, a play key, a stop key, or the like of the video remote controller may be used instead of the channel key. However, when the VCR is operating, the VCR may malfunction when the automatic turntable 1 is operated. Therefore, for example, a playback key during a playback operation, a recording key during a recording operation, etc. The device is operated using a key that does not significantly affect the current operation status of the device. Further, a plurality of the receiving units 11A are provided, and a position of the remote controller 5 is detected by detecting a time difference or the like of a transmission signal received from the receiving unit 11A, and the rotation of the rotation 3 is automatically stopped in that direction. May be. As described above, the operation method and operation of the automatic turntable 1 can be arbitrarily changed by changing the operation program stored in the storage unit 14 and the type or structure of the reception signal 21, and it is widely used at present. It can be operated using a remote controller attached to a device that is widely used. In addition, other than the above-described changes, it is needless to say that it can be appropriately changed by those skilled in the art.

[0017]

As described above, according to the present invention, a channel key of a remote controller is operated to receive a transmission signal output from the remote controller, and to output a reception signal according to the reception result. Means, storage means for storing a plurality of channel codes different for each remote control as the received signal, the received signal output from the receiving means,
Detecting whether or not the received signal is a channel code stored in the storage means, and if the received signal is the channel code stored in the storage means and continuous for a certain period or more, rotates the rotating unit. And a control means for outputting a driving signal for the television receiver, so that the operation of the channel of the television receiver and the turntable can be performed simultaneously when the function of rotating the television receiver is not provided in advance. Also, even if the channel key selected on the remote controller is continuously operated for a certain period or more, the channel selected on the television receiver does not change, so that the screen orientation of the television receiver can be freely changed while watching the image on the television receiver. be able to.
For this reason, it is not necessary to separately provide remote controllers for selecting the television receiver and for the rotary table, so that the cost is reduced and the usability is improved. Furthermore, it is possible to easily select a television receiver and rotate the turntable by operating a remote controller without depending on the manufacturer, simply by mounting a plurality of TV sets of different manufacturers on the turntable.
