Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a remote controller for remotely operating a device to be operated.

[0002]

2. Description of the Related Art In recent years, a remote controller (hereinafter referred to as a remote controller) has been attached to almost all of home audio equipment and video equipment in particular, and the remote controller can be used to remotely control the above equipment. However, each year, as the number of devices used increases, the number of operating devices such as remote controllers also inevitably increases, and there has been a problem that management of the remote controllers becomes cumbersome. In addition, the number of functions to be operated by the remote controller is increasing, and the number of operation keys is inevitably increased, thereby causing a problem that the operation of the remote controller becomes complicated.

In order to cope with the above problem, a video tape recorder (hereinafter referred to as V
There is a remote control (referred to as TR) provided with an operation key of a television on the remote control of the VTR so that one remote control can operate two devices. However, this VTR remote control uses not only TV operation keys, but also V
Operation keys from simple recording, playback, fast forward and rewind of TR to answering machine and memory function are also required,
The number of operation keys increases. In view of this, there is a method in which an opening / closing mechanism and a slide mechanism with a lid are further provided to simplify the operation of the remote controller by classifying the key layout by function. Also, multiple remote controls
Remote control management such as a centralized remote control that can be operated by selecting the manufacturer of each operated device and a remote control with a learning function that reads and stores the transmission data transmitted by the remote control attached to each device so that it can be combined into one remote control Some emphasized.

[0004] For example, in Japanese Utility Model Publication No. 2-8466, as a remote control for operating a television and a VTR, a television operation transmitting unit is provided at one end in a longitudinal direction so that operation is easy even if the number of operation keys is increased. There has been proposed a remote control in which a VTR operation transmitting unit is provided at one end and a device to be operated is determined by sliding a lid provided on an upper portion of the remote control. Japanese Utility Model Publication No. 4-50714 proposes a remote controller that allows a user to change the layout of operation keys according to the usage environment with the same intention.

[0005] However, including the unified remote controller,
In the above-mentioned conventional example, since the number of operation keys physically increases after all, it is not a fundamental solution for the management of the remote controller and the operation of the remote controller.

[0006] Regarding the management of the remote control, if the number of devices operated by one remote control is increased, the number of operation keys must be increased. If one considers an appropriate size of the remote control itself, one remote control is required. There is a limit to the number of devices operated by. For the same reason, the number of functions that can be operated by one remote control is also limited.

[0007] Further, with respect to the operation of the remote controller, as the number of operation keys increases, when a user, especially a child or an elderly person who only requires basic operations, operates, he / she may be confused by searching for operation keys. There is a possibility that the operation mode may be too complicated to operate. Furthermore, with the increase in the number of operation keys, the operation keys themselves must be very small considering the appropriate size of the remote control itself,
There is a risk of erroneous operation.

[0008]

SUMMARY OF THE INVENTION An object of the present invention is to provide an unspecified number of devices or an unspecified number of functions of each device with a single remote controller by using new operation means not using conventional operation keys.

The lower case 5 is provided with a position fixing switch SW for fixing a display screen frequently switched on the display device 1.

First, a method of operating each operated device with the remote controller of the present invention will be described. FIG. 3 is a diagram showing an example of a display screen of the display device 1 when each operated device is operated by the remote controller of the present invention. First, an initial screen displaying the design and name of each operated device is displayed as shown in FIG. 3A. On the initial screen, operation commands for switching to a screen for operating the operated device are displayed, such as "TV" for a TV, "VTR" for a VTR, "CD" for a compact disc, "LD" for a laser disc, and an amplifier. Indicates "Amp" and the tape deck is "Tape". Further, at the lower right of the initial screen, an operation command "setting" for use in storing an infrared control signal from a remote controller attached to each operated device in the remote controller of the present invention is displayed. On this screen, the user first selects a device to use, and presses the design command displayed on the initial screen.

For example, when the user wants to operate the VTR, he only has to select and press the "VTR" displayed on the initial screen.
When pressed, the display screen is switched, and the basic operation screen of the VTR is displayed as shown in FIG. 3B. On the basic operation screen of the VTR, operation commands for performing basic operations of the VTR, that is, reproduction, recording, fast forward, rewind, stop, channel selection, power on / off operation, are displayed by symbols, characters, and the like. In addition, an operation command “Menu” for switching to a screen for operating the VTR in more detail and an operation command “Return” for returning to the screen before switching are displayed at the upper right of the basic operation screen of the VTR.

If you want to operate the VTR in more detail,
What is necessary is just to select and press the "menu" displayed on the basic operation screen of the VTR, and when pressed, the display screen switches,
The detailed operation screen of the VTR is displayed as shown in FIG. 3C. V
On the detailed operation screen of the TR, an operation command for switching to a screen for performing various detailed operations is displayed, and "image quality" is displayed on a screen for adjusting image quality, and "image quality" is displayed on a screen for setting recording specifications. "Recording specifications", "Channel setting" to the channel setting screen, "Reservation" to the reservation screen, "Date setting" to the date setting screen, and "Option" to the option screen are displayed. ing. Also,
At the upper right of the detailed operation screen of the VTR, an operation command “return” for returning to the screen before switching is displayed, following the previous screen. Although not shown, a screen for performing various detailed operations is switched to a screen for performing more detailed operations depending on the operation. Thus, detailed operations can be performed as needed.

If the user wants to operate the TV while the detailed operation screen of the VTR is displayed, the user can select and press "return" displayed on the detailed operation screen of the VTR.
When pressed, the display screen returns to the basic operation screen of the VTR in FIG. 3B, and when "Return" is selected and pressed, the display returns to the initial screen in FIG. 3A. In this way, by "return", the display screen is sequentially retreated and can return to a required screen. When “TV” displayed on the initial screen is selected and pressed, the display screen is switched, and a basic operation screen of the TV is displayed as shown in FIG. 3D. On the basic operation screen of the TV, basic operation of the TV, that is, operation commands for selecting channels 1 to 12, adjusting the volume, and turning on / off the power are displayed by symbols, characters, and the like. In addition, the above-mentioned “menu” and “return” operation commands are displayed at the upper right of the basic operation screen of the TV. If you want to operate the TV in more detail,
It is sufficient to switch to the detailed operation screen of the TV by the operation command “menu” as in the description of R. The screen for performing various detailed operations is switched to a screen for performing more detailed operations depending on the operation. When it is desired to operate another operated device, the display screen may be returned by the operation command “return” as in the description of the VTR.

As described above, for the other operated devices, the operated device is specified by the operation command on the initial screen of FIG. 3A, and the basic operation screen as shown in FIG. 3B, the detailed operation screen as shown in FIG. Alternatively, the screen can be switched to a screen for performing more detailed operations, and the specified operated device can be operated.

When each operation command is selected and pressed on each display screen, a control signal unique to each operation command for operating each operated device is emitted to each operated device.
The operation specified by each operation command is executed in each operated device.

As described above, the display screen of the remote controller according to the present invention is divided into layers, the basic operation is in a shallow hierarchy, the more detailed operation is in a deeper hierarchy, and when a more detailed operation is desired, the operation is sequentially performed. The target screen is selected by making the hierarchy deeper. Further, since the display screen is configured to be switched hierarchically as described above, even if the range to be pressed becomes narrower when the number of operation commands is increased on the display screen of FIG. 3A or FIG. 3C, the display of FIG. 3A or FIG. A plurality of screens can be prepared and operation commands can be divided and selected. In this case, "NEXT" or the like may be prepared as an operation command to switch between a plurality of display screens. For this reason, the number of operation keys does not increase more than necessary within a certain area as in the related art, and an unspecified number of operated devices,
Any number of operation commands corresponding to an unspecified number of functions can be prepared. In addition, since the display screens are switched in a hierarchical manner, the operation can be performed according to the user's purpose, and the operation is sharpened. In addition, since the basic operation is at a shallow level, the user only needs to switch a few display screens for the basic operation, and the operation is easy. Also, since the number of operation commands does not increase more than necessary within a certain area, it is possible to have a sufficient area for pressing one operation command, and to perform erroneous operations such as pressing two or more keys as in the past. You will not do it.

Next, a description will be given of a method for enabling the operated remote controller to be controlled by the remote controller of the present invention when each operated device is operated by the attached remote controller. There are two ways to do this
One is to initialize the operation mode already incorporated at the time of commercialization of each operated device on the display screen of the remote controller of the present invention, and the other is to operate each operated device with the attached remote controller. This is a method of directly storing the control signal at the time of the remote control in the remote controller of the present invention. In the former case, the above-mentioned operation mode is an infrared radiation pattern (frequency), which is assigned to each product maker. Therefore, if the control pattern of the infrared device is incorporated in the memory of the remote controller in advance, the user can perform the initial setting only by specifying and inputting the maker name of the device to be used in the remote controller of the present invention.

First, a method for initially setting the operation mode on the display screen of the remote controller of the present invention will be described. FIG. 4 is a diagram showing an example of the display screen of the display device 1 when the operation mode is initialized on the display screen of the remote controller of the present invention. For example, if you want to make initial settings for VCR of Company A,
As explained in the remote control operation of each operated device above,
The display screen is switched to the detailed operation screen of the VTR shown in FIG. 4c (same as FIG. 3c), and “option” displayed on the detailed operation screen of the VTR is selected and pressed.

On the setting screen of the TR, operation commands for setting the operation mode of each maker are displayed with each maker name. Here, when "Company A" is selected and pressed, it is designated and input that the VTR is made by Company A in the remote controller of the present invention, and the initial setting is completed. Thus, the remote controller of the present invention is a VTR of Company A.
Can be operated.

As described above, with respect to other operated devices of other manufacturers, "option" on the detailed operation screen as shown in FIG. 4c and "setting" on the option screen as shown in FIG. 4e.
Is selected and pressed, the screen is switched to a setting screen as shown in FIG. 4F, and the initial setting of the operation mode can be performed.

Next, a method for storing a control signal when each operated device is operated by the attached remote controller directly in the remote controller of the present invention will be described. FIG. 5 is a diagram showing an example of a display screen of the display device 1 when a control signal when each operated device is operated by an attached remote controller is directly stored in the remote controller of the present invention. FIG. 6 is a diagram in which a control signal is sent from a remote controller attached to each operated device to the remote controller of the present invention and stored. For example, in the case where a control signal when a certain VTR is operated by the attached remote controller is directly stored in the remote controller of the present invention, the initial screen of FIG. When the displayed "VTR" and "setting" are pressed at the same time, FIG.
A basic operation screen of the VTR in which “setting” is added to the basic operation screen of FIG. 5 is displayed as shown in FIG. 5G. VT in this state
A control signal when R is basically operated by the attached remote controller can be input into the remote controller of the present invention. For example, V
When the TR inputs a control signal when the power is turned on and off with the attached remote controller into the remote controller of the present invention,
As shown in FIG. 6, the infrared light receiving section 4 of the remote controller R of the present invention in a state where the basic operation screen is displayed and the infrared light emitting section of the remote controller r attached to the VTR face each other.
When the "power" key D of the remote controller R of the present invention is pressed simultaneously with the operation of the power key d 'of the remote controller r attached to the remote controller r, the input of the control signal in the remote controller of the present invention is completed. Thus, the remote controller of the present invention can perform power on / off operation for the VTR.

As described above, regarding other operation keys and other operated devices, as shown in FIG. 6, a screen to which "setting" is added (for example, a basic operation screen as shown in FIG. 5g, or FIG. 5g) 5h, the remote control of the present invention is displayed by pressing the “menu” of FIG. 5) and the remote control attached to the operated device. Go at the same time,
Control signals can be input. After all the input of the control signal related to the necessary operation command is completed,
If "return" is sequentially pressed and the screen is returned to the screen in FIG. 5A, it is determined that the setting operation has been completed, and "setting" is not displayed in the subsequent screen switching.

As described above, in the remote controller of the present invention, the operation mode is initialized on the display screen of the remote controller of the present invention, or a control signal when each operated device is operated by the attached remote controller is directly transmitted to the remote controller of the present invention. This makes it possible to control each operated device with the remote controller according to the present invention, so that preparation before remote control can be performed is very simple.

Lastly, a description will be given of the operation of the remote controller of the present invention for each user and the setting thereof, which is different from the general operation of the remote controller of the present invention as described above. For example, it is thought that elderly people will have difficulty in operating the remote control because their vision and thinking ability will decline, and foreigners will not understand Japanese displayed on the remote control screen, and it will be difficult to operate the remote control again It is expected to be. In view of these circumstances, the remote controller of the present invention has a larger operation command on the screen, a mode for elderly and children who can concentrate on the basic operation, and a mode for foreigners who can switch the display language. User-specific operation modes such as modes are provided.
