5 (a) and 5 (b) are explanatory views showing another embodiment in the invention of claim 1, (a) is an external view of a remote controller, and (b) is a corresponding menu table. It is an example. In the embodiment of FIG. 1, "+" for moving the cursor,
Although the "-" key was arranged vertically and the menu display was also displayed correspondingly, in the present embodiment, the cursor moving keys 3b and 3c are arranged horizontally (M
(The ENU and ENTER keys are the same as in Fig. 1), and the corresponding menu display is displayed at the bottom of the screen.
The operation is similar to that of the embodiment shown in FIG.

6 (a), (b), (c), and (d),
It is a figure which shows the modification of the operation part of the remote control in the said Example.

First, FIG. 6A shows an example in which the "PLAY" key 3e and the "STOP" key 3f, which are conventional independent keys, are also used as the "+" and "-" keys in the above embodiment, and the menu is displayed. During display, it functions as a cursor up / down key.

FIG. 6B shows an example in which the encoder formed by the roller 3g is used for the "+" and "-" keys of the menu. An output signal generated by rotating the roller 3g in the forward or reverse direction moves the vertical menu display cursor up / down. It should be noted that the roller 3g may be arranged so as to be horizontally rotatable, and in this case, the cursor is moved to the left / right as the horizontal menu display shown in FIG. The same applies when the roller section is provided with the function of the ENTER key.

6C and 6D show "+" and "-".
This is an example in which "enter" (ENT) keys are arranged between the keys, and in (c), "+" for independent cursor movement,
The "Enter" key 3d is arranged in the center of the "-" keys 3b and 3c. In (d), the "+" and "-" keys are used as seesaw-shaped keys 3h, and when the center is pressed, the function of "Enter" is given. ing.

Next, an embodiment of the invention of claim 2 will be described. 7A and 7B are an external view (a) showing the configuration of the remote controller of this embodiment and a perspective view (b) showing the key structure. In this embodiment, the "playback" (P
LAY) key 9a, "rewind" (REW) key 9b,
"Fast-forward" (FF) key 9c, "Stop" (STO
P) The double-structured key 10 is used for each of the keys 9d. This double-structured key 10 includes a tact switch 10b.
The touch switch 10a has a structure in which the touch switch 10a is superposed on the touch switch 10a, and the touch switch 10a is first turned on when lightly touched, and the tact switch 10b is also turned on when pressed, which enables a two-step operation.

FIG. 8 is a block diagram showing the circuit configuration of this embodiment. Basically, the configuration is the same as that of FIG. 2, except that the key output signal from the operation unit 9e of the remote controller is due to the key 10 having the double structure and the control unit 6
This is a point that the mode transition processing is not required in the processing of. The screen display function performed using the screen display unit 7 and the confirmation sound generation function performed using the confirmation sound output unit 8 are the same as in the case of FIG.

FIG. 9 is an explanatory diagram showing an operation example according to this embodiment. Here, an example is given in which it is desired to press the PLAY key without looking at the operation unit. First, touch what appears to be the PLAY key. Then, a confirmation sound beeps and the key layout is displayed on the screen as shown in (a), and the touched key position is blinked and displayed. In the illustrated example, it can be seen that the key is not the PLAY key but the FF key. Since the user is shown to have the PLAY key next to the FF key, the user moves his / her finger next to it and touches it. As a result, a confirmation sound with a beep and a confirmation sound as shown in FIG.
As the screen display changes and the display of the PLAY key blinks, it can be seen that the PLAY key is touched. If the user presses the PLAY key as it is, the key layout display on the screen disappears with a beeping sound as shown in FIG. 9C, and the PLAY command is issued to the VTR. In the above, the confirmation sound can be distinguished when the command is issued and when it is not issued.

As described above, according to the present embodiment as well, even when it is difficult to see the operation portion of the remote controller as in the case of using the spectacles type viewer, the remote controller operation of the VTR can be performed and the number of keys can be reduced. Since the number can be increased, the operation can be made into another function.

In addition to the combination of the touch switch and the tact switch, the double structure key may be a tact switch that reacts with a heavy load and a tact switch that reacts with a light load stacked. In this case, the configuration is the same as that of the touch key + tact switch except that it is necessary to press lightly instead of touching it first.

Further, as another embodiment of the invention of claim 2, a remote controller using a key having the same structure as the conventional one consisting of only a sheet switch or only a tact switch is used and connected in the same manner as in FIG. And input to the control unit 6.
In the present embodiment, in response to the above-mentioned "touch / push" or "lightly push / strong push", "press / push again" causes the control unit to make a judgment process, and the same processing as in the above-mentioned embodiment of FIG. Realize actions and effects. In the example of using the sheet switch as the operation key, first, pressing the key that you think is around here will display the layout of the operation part, and the pressed key will blink and be displayed, so if the key you want is your finger Release it, press it again, and if it is different, just move your finger to the desired key. In the example in which the tact switch is used as the operation key, the operation is almost the same as in the case of the above sheet switch, but when the finger is moved to the next,
Due to the structure, it is necessary to remove the finger from the operation unit once.

Next, an embodiment of the invention of claim 4 will be described. In this embodiment, an AV device (for example, a remote controller that may be used for a long time focusing on video / audio) (for example,
In this embodiment, a VTR and an eyeglass-type viewer are assumed.)
In order to solve the problem of fatigue in, the warning message of long-time use is displayed on the screen that is actually used in an appropriate form to call attention and encourage correct use and operation. Is.

In this embodiment, a control signal from the controller 6 instructs the AV equipment (video output device) such as a VTR to turn off the power. The command generator 11 may be built in the controller 6.

FIG. 11 is an explanatory view of the operation and action of the embodiment having the above-mentioned configuration, showing a display example of the monitor screen. First, the control unit 8 warns the user with a warning message as shown in Fig. 11 (a) when the power is turned on: "This system automatically turns off the power within 3 hours. Be careful of fatigue."
Is displayed on the monitor screen for a fixed time (for example, 10 seconds).
During this display, the operation of the AV device is invalid, and a confirmation sound is output when the display ends. Subsequently, the elapsed time of use is displayed as shown in FIG. 11B at all times or every time a certain period of time elapses. Next, after a lapse of a predetermined time (after 3 hours in this example), a warning message "Long use is started,
3 hours have passed. Is displayed for a certain period of time (for example, 10 seconds) (Fig. 11 (c)), and then a power-off warning message "Three hours have passed since the start of use. Turn off the power." It is displayed for 10 seconds (FIG. 11 (d)), and a power off command is sent to the AV equipment. As described above, the user's fatigue is prevented.

For the sake of simplicity, only when the power is turned on, a warning message "Please be careful about fatigue." (Fig. 11)
11 (a ') and FIG. 11 (a').
(B) is displayed, or FIG. 11 (a ′) → FIG. 11
You may display (b)-> FIG.11 (c). Further, this warning function may be incorporated in the AV device or the viewer.

Next, an embodiment of the invention of claim 5 will be described. In this embodiment, in a remote controller which is operated by being supplied with power from a battery of an AV device such as a VTR, when the battery cannot be operated due to battery down, not only the operation itself is stopped but also the AV device of the main body is operated in conjunction with the power supply.

Reference numeral 1 is an AV device such as a VTR, 6 is a control unit, and in this embodiment, it operates by receiving power supply from the battery of the AV device 1. A power supply, signals (video, audio), and commands are connected to the remote controller 3 by cables. Reference numeral 12 denotes a battery down detection unit corresponding to the remaining battery level detection means, and the control unit 6 receives the detection signal of the battery down detection and sends a power off command to the AV device 1 via the command generation unit 11.

FIG. 13 is a flow chart showing the operation of this embodiment. AV equipment which operates on a battery normally detects a battery down, and when it is judged that the battery is down, the power of the main body is turned off and the remote controller is operated. Also stop the power supply to. Here, if the remote control becomes inoperable before the power supply voltage drops and the main body detects that the battery is down, the operation of the main body may be abnormal, and correct operation may not be possible. Therefore, in the present embodiment, the detection of battery down, which is not performed by normal peripheral devices, is detected by the remote controller before the main body detects the battery down, and the internal power supply of the remote controller is turned off to operate the operation unit. At the same time as preventing the remote control command from being sent, the main body side is requested to turn off the power so that the power states of both are the same and the system consistency is maintained. When a peripheral device other than the remote controller is connected, the power of the device is also turned off in conjunction with it. In addition, this embodiment is an AV
It is also applicable to devices other than equipment.
