Abstract

PURPOSE:To make it possible to confirm the operation state of a remote control device main body at a distant place by providing the main body that records or reproduces an image or a sound with a means to receive a signal representing the operating state from the main body and display it. CONSTITUTION:From a transmission part 4 to the reception part 9 of the device 8 to record/reproduce an image or a sound, signal is transmitted through operating the respective switches 12-17 of the remote control 1 from a transmitter 4 to execute such operations as the turning on/off 12 of a power source, reproduction 13, recording 14, fast forward winding 15, rewinding 16, and stopping 17, etc. The transmission part 11 of the device 8 transmits the operating state of the main body, while the reception part 5 of the remote control 1 receives this, decodes 6 it, and displays the state of the recording/reproducing device 8 in a display part 7 via a CPU 2. As a result, even from a place distant from the main body, the operating state of the main body can be confirmed near at hand.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a remote control device used for, for example, equipment equipped with a function of recording or reproducing images and sounds.

[Prior Art] Conventionally, remote control devices used for televisions, VTRs, audio equipment, etc. have a power supply of 0N10.
It has buttons for FF, playback, frame advance, channel setting, etc., and if you want to perform a certain operation on the device when you are away from the device, press the button corresponding to that operation.

[Problems to be Solved by the Invention] However, with the above-mentioned conventional remote control device, it is not possible to check the operating state of the main unit by simply issuing an operating command to the main unit. Originally, remote control devices are operated from a remote location, so you can check the operating status of the device itself, such as whether it is recording or playing back, or if it is recording, the remaining recording capacity. The drawback was that you had to get close to the device itself to check the number.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above-mentioned problems and provide a remote control device that allows checking the operating status and information of the device body even from a remote location.

[Means for Solving the Problems] The present invention provides a display section that displays operation information based on signals indicating operation information from two device bodies that have a function of recording or reproducing at least one of images and audio. and operation information and command information for specifying a desired operation to the main body of the device, as well as means for managing the display operation of the display section.

[Function] According to the present invention, by providing the remote control device with a display section for notifying operational information of the device main body, the operator can check the operational information at hand even from a location away from the device main body. This is how it was done.

[Example 1 Hereinafter, the present invention will be explained in detail using the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention.
2 is a remote control device; 2 is a CPU that is operated by the operator to cause the device main body 8 to perform a desired operation; and 3 is an encoder that encodes the command signal into a transmission signal; 4 is a CPU that generates a command signal based on the command signal. a transmitter that transmits the encoded signal to the recording/reproducing device 8;
9 is a receiving unit that receives signals sent from the remote control device 1; IO is a recording/reproducing unit that performs operations such as recording and reproducing specified by the operator based on the signals received by the receiving unit 9; A transmitting unit that transmits an information signal from the recording/reproducing unit IO to the remote control device 1; 5 is a recording/reproducing device 8;
6 is a decoder that decodes the information signal from the receiving section 5; 7 is the CPIJ
This is a display unit such as a liquid crystal display or a light emitting diode that displays information from 2.

In FIG. 1, an operator at a location away from the recording/reproducing device 8 first specifies a desired operation to the CPU 2 using the operation switch buttons 12 to 17 of the remote control device 1. Here, the operation switch button is the power source 0 shown in Figure 2.
N10FF button 12. Play button 13, record button 1
4. Fast forward button 15. Rewind button 16. This corresponds to the stop button 17 or the like.

For example, the second
When the record button 14 shown in the figure is pressed, the command signal is encoded by the encoder 3 and transmitted from the transmitting section 4 to the receiving section 9 of the recording/reproducing device 8.

This information signal is transmitted to the recording/reproducing section 10, where recording is performed. When recording is started, an information signal indicating that recording is in progress is output to the transmitter 11, and the information signal is sent to the receiver of the remote control device 1. The information signal received by the receiving section is decoded by the decoder 6 into a signal to be given to the PO2, and an indication that recording is in progress is displayed on the display section 7 according to an instruction from the CPU 2.

Similarly, information indicating whether playback is in progress or fast forwarding is being displayed on the display section. Furthermore, if recording is in progress, the remaining recordable time may be displayed.

Further, the CPU 2 manages the operation status of the main body so that, for example, during recording, operations on the fast forward or rewind buttons are not accepted, and the operation in progress is not disturbed by pressing other command buttons. In addition, command signals based on commands from the switch buttons 12 to 17 can be sent directly to the display unit 7 via the CPU 2 to display the contents of the operation commands.In addition, the CPU 2 has a display content selection function. You can also select the content to be displayed.

Note that the recording/reproducing device 8 in the embodiment described above is, for example, a V
A device that records and plays back images and sounds, such as a TR, audio recorder, electronic still camera, and still video recorder. Further, the present invention can also be applied to devices having at least one of recording and reproducing functions, such as televisions, record players, CD players, etc.

Electronic still cameras and still video recorders can display the number of empty tracks (9), whether they are images or audio, and televisions can display the number of the channel currently being viewed on the display.

Further, the remote control device and the device main body may be connected wirelessly or wired.

[Effects of the Invention] As explained above, according to the remote control device of the present invention, since it is provided with a display section that displays the operation contents of the device main body, the operation information can be viewed even from a place far from the device main body. This has the effect of allowing you to quickly check the contents of the command at hand.
