Description

[Detailed description of the invention] The invention is used in combination with a television receiver. The present invention relates to a recording operation display device for a magnetic recording and reproducing device equipped with a television broadcast receiving function.

A magnetic recording and reproducing device (hereinafter abbreviated as VTR) equipped with a television broadcast receiving device is used in combination with a television receiver (hereinafter abbreviated as television), and the user records a specific program using the VTR. Generally, the following operations are required.

(1) Set the TV receiver's reception channel to the VTR monitor channel.

(2) Select the program you want to record using the TV reception tuner that comes with the VTR.

(3) Start recording.

However, the operations described above are difficult for general users unfamiliar with VTRs to understand, and especially when operating the VTR, it is easy to select the wrong channel to record, which may result in recording failure.

An object of the present invention is to eliminate the above-mentioned drawbacks of the prior art and to provide a recording operation display device that makes it easy to understand and difficult to make mistakes when recording a VTR.

The key point of this invention is that the necessary operation points for recording on a VTR are displayed by flashing lamps, and by operating according to the display, the TV tuner can be used to select the VTR monitor channel. The attached recording channel is received on the television so that the user can clearly see the program he or she wants to record, thereby making the operation at the time of recording easy to understand and reducing errors.

Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a conceptual diagram in which a television 1 and a VTR 2 are used in combination. The antenna 3 is connected to the antenna terminal 3a of the VTR 2, and one side distributed by the antenna terminal 3a is sent to the antenna output selector switch 4.
The other end is connected to tuner 5 inside the VTR. The antenna changeover switch 4 connects the VTR monitor signal when switched to the a side, and connects the output of the RF converter 6 that converts the reproduced signal to a high frequency when switched to the b side. The center point of the changeover switch 4 is connected to the antenna terminal board 7 of the television 1. One of the channel selection sections 8 of the television 1 is set for use as a VTR monitor.

FIG. 2 is a conceptual diagram showing an embodiment of the present invention, and in addition to the general functions explained in FIG. 1, a display function which is a feature of the present invention is shown. A channel 9 dedicated to the VTR monitor is set in the channel selection section 8 of the television 1, and when this channel is selected, the reproduced image of the VTR or the image received by the tuner of the VTR is displayed on the cathode ray tube 16.

The television 1 is provided with a switch 10, and the television 1 and the VTR 2 are connected through a connection 15 for additional functions other than the antenna line. Here, when the user wants to record, switch 10.
When operated, the display lamp 13 and display lamp 14 near the recording lever 11 and tuner knob 12 of the VTR 2 flash to inform the user of the location to be operated when recording. In particular, the Chiyuna display has the effect of reminding users to correctly select the program they want to record. Further, by operating the switch 10, the channel selection unit 8 of the television 1 is automatically set to the VTR monitor channel 9, and since the image received by the tuner of the VTR 2 is displayed on the cathode ray tube 16, it can be confirmed visually.

FIG. 3 is an example of a block diagram showing the circuit configuration of the recording operation display device of the present invention, in which a power source 21 and a push button switch 22 (corresponding to switch 10 in FIG. 2) are connected, and after switch 22, A voltage holding circuit 23 is connected. This voltage holding circuit 23 is composed of a flip-flop circuit, detects a voltage change when the switch 22 is pressed, sets the flip-flop, and applies a control voltage to the oscillation circuit 24. The oscillation circuit 24 is a low frequency rectangular wave oscillation circuit, and is generally preferably an astable multivibrator type oscillation circuit. The lamp blinks by intermittent current flowing through the light emitting diode 25 using the output of the oscillation circuit 24. Approximately 2 Hz is considered to be suitable as the oscillation frequency.
The holding circuit 23 is activated by voltage detection during VTR recording.
It is also easy to reset it so that it stops blinking when the VTR starts recording.

Voltage holding circuit 23 oscillation circuit 24 is a logic gate
It is easy to configure the circuit using an IC, but it is also possible to use a transistor type. Further, a terminal 26 is taken out from the switch 22, and this voltage is used as a trigger voltage for an electronic channel selection device, so that when the switch 22 is pressed, a VTR monitor channel is automatically set.

Since the present invention is as described above, it is possible to
When used in combination with a VTR, the operation is easy to understand and recording failures can be prevented when recording television broadcasts.
