Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a television receiver with a recording / reproducing device, which is constructed so that the recording / reproducing device can be mechanically separated from the television receiver.

(B) Conventional technology In recent years, Japanese Patent Publication No. 59-32034 (H04N5 / 4)
As shown in 4) and the like, there has been proposed a TV receiver with a VTR in which a recording / reproducing device (hereinafter referred to as VTR) and a television receiver (hereinafter referred to as TV receiver) are incorporated in a common cabinet.

Such a TV receiver with a VTR is usually as shown in FIG.
TV tuner (10) and VTR tuner (20),
TV controller (11) and VTR controller (21)
Is controlled by a controller, and an operation command signal from one key input device (3) such as a remote control transmitter is sent to both controllers (11).
It is configured to be input to any of (21). Then, the signal bus line (4) exchanges signals between the both controllers (11) and (21).

By the way, in the above device, when a failure occurs in the VTR, as shown in FIG.
There is a configuration in which only TR (2) can be separated. Then, when the VTR is separated by a failure, normally,
Either the TV receiver is completely deactivated, or only the TV receiver related keys are selected by the user and the TV receiver is operable.

By the way, in the former case, the advantage that the VTR can be mechanically separated is not fully utilized, and the TV receiver cannot be used during the VTR failure, which is inconvenient. In the latter case, VT
Of the R-related operation keys, if the operation key for controlling the operation of the TV receiver at the same time as the VTR is operated by mistake, the TV receiver may be inconvenient.

For example, when the playback key is operated, the TV channel is locked to the specific channel, and the TV receiver cannot be selected.

(C) Problems to be Solved by the Invention The present invention has been made in view of the above points, and in the state where the VTR is separated from the TV receiver, even if the VTR-related operation key is erroneously operated, the TV image is received. (EN) Provided is a television receiver with a recording / playback device which has no influence on the operation of the device.

(D) Means for Solving the Problems The present invention provides a detecting means for detecting a state in which a recording / reproducing apparatus is separated from a television receiver, and an operation command for the recording / reproducing apparatus and the television receiver. A key input device and a key input determination unit that determines the key input from the key input device and invalidates the key input related to the operation of the recording / playback device when the separated state is detected by the output of the detection unit.

(E) Operation The present invention functions to invalidate the VTR-related key input by the key input determination section when the detection state of the VTR is detected.

(F) Embodiment One embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of the apparatus of this embodiment. The signal bus line (4) is connected to the TV controller (11),
VTR that manages input / output data to the controller (21)
Controller input / output means (111), detection means (112) for detecting whether or not the VTR is separated from the TV receiver by looking at the connection state of the signal bus line (4),
When the operation command signal from the key input device (3) is interrupted and the data is output at all times and the detection state of the VTR is detected by the detecting means (112), the operation command input related to the VTR is invalidated and data is Key input determination means (113) that does not output any information and the key input determination means (11)
3) A channel selection data output means (114) which is supplied with an output and outputs a channel selection voltage to the TV tuner (10).

Next, the operation of the above circuit will be described.

First, when the VTR (2) is integrated with the TV receiver (1) in a normal state, the operation command from the key input device (3) is decoded by the key input determination means (113). Then, the VTR-related command is supplied to each output section in the VTR controller (21) via the VTR controller input / output means (111) and the signal bus line (4) to control the VTR tuner (20) and the like. It Also, TV-related operation commands are channel selection data output means.
It is supplied to the output section such as (14) and the TV tuner (10) and the like are controlled.

An operation command for controlling both the TV and VTR is supplied to each predetermined output section in both controllers (11) and (21), and
The R and TV receivers work together. For example, when the playback key is pressed, the VTR enters the playback state, the TV tuner (10) is locked to the empty channel, and the playback image is not displayed.

Next, when the VTR is separated from the TV receiver due to a failure, the detection means (112) detects the separated state and supplies the detection output to the key input determination means.

Therefore, when a VTR-related operation command or an operation command for controlling both the TV and the VTR is input to the key input determination means (113), this command is invalidated and is not output to any output unit. That is, the TV tuner (10) is not locked to the empty channel even if the reproduction key is operated.

On the other hand, when a TV-related operation command is input, even if the detection output is input, the key input determination means (113) transfers data to the channel selection data output means (114) and the like to operate the TV receiver normally. Control like time.

(G) Effect of the Invention According to the present invention as described above, in the state where the VTR is separated from the TV receiver, even if the VTR-related key is accidentally pressed, the operation of the TV receiver is not affected at all. .
