Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video reproducing apparatus such as a VTR capable of efficiently cueing a recording medium in a short time.

[0002]

2. Description of the Related Art Conventionally, FF (fast forward) or REW (rewind) and C are used when a desired picture is cued when a VTR is played back, that is, when a so-called picture search is performed.
Each of the UB (REV) operation modes is used to reach the desired point of the tape. In this case, the tape speed is, for example, about 40 to 100 times higher than the standard speed in FF or REW, but CUE or R
EV is 5 to 20 times slower than FF or REW. Also, the monitor screen cannot be seen with FF or REW, but C
A monitor screen can be seen on the UE or REV.

Therefore, when the cue point of the tape is far from the current position, the tape is first run at a high speed to the vicinity of the cue point with FF or REW, and then CUE or R is reached.
While switching to EV and watching the monitor screen, normal PB (playback) is started at a desired point.

[0004]

However, in this case, in the VTR, in the FF or REW, the CUE or REV is used.
When the button is pressed, CUE or REV is performed only while the button is pressed, and when the finger is released from the button, the PB mode is immediately set. Therefore, FF or REW to CU
If the image when switching to E or REV is still far from the desired point, remove your finger from the CUE or REV button and operate the FF or REW button again to run the tape at high speed again. I won't.

As described above, in the conventional VTR, when the CUE or REV button is released, the PB mode is always entered. Therefore, when the picture search is performed, the CUE is set only during FF or REW. Or when inserting REV and moving to FF or REW again, FF or RE
It was necessary to press the W button again, which was very inconvenient.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. As shown in FIG. 1, the present invention shows that when the FF or REW button is pressed at time t ₁ to run the tape at high speed,
_The CUE or REV mode is set at ₂ hours or t _{4, and} when it is released at t ₃ or t ₅ , the original FF or REW mode is automatically set. By doing this, when performing a picture search, while the tape is FF or REW, sometimes the CUE or REV
Then you can see the monitor screen. Therefore, it is possible to easily run the tape at a high speed while looking at the screen from time to time to the closest point to the desired point without particularly complicated button operation, and thus the cue can be performed efficiently in a short time. . Moreover, if you look at the monitor screen during CUE or REV and the cue point is approaching, press the PB button at that time to switch to PB mode, set the CUE or REV mode, and then almost cue while watching the monitor screen. When the point is reached, the CUE or REV mode can be canceled and the PB mode can be automatically shifted, so that the cue can be performed efficiently in a shorter time.

To set the CUE or REV mode,
Specifically, the following method can be considered.

(1) Provide a dedicated CUE or REV button,
CU only when the button is pressed during FF or REW
Enter E or REV mode.

[0010]

[0011]

(2) CUE or REV is set only when the pause button is pressed during FF or REW.

(3) When the pause button is pressed during FF or REW, the pause button is locked to enter the CUE or REV mode, and it is not released until the pause button is pressed again.

FIG. 2 conceptually shows a circuit configuration for carrying out the method of the above item (1).

Terminals 1, 2, and 3 have PB buttons,
When the CUE or REV button or the FF or REW button is pressed, an "H" (high level) signal is added. On the other hand, the system control circuit 4 using a microcomputer sends a control signal CTL to a predetermined circuit according to the instruction signal when each mode is set, and sets the instructed mode.

Now, for example, the PB mode is set,
An "H" signal is applied to terminal 1, and AND gates 5 and 6
Shall be open. In this state, CUE or R
When the EV button is pressed, a signal of "H" is applied to the terminal 2, and this signal drives the operation control circuit 9 through the AND gate 5. As a result, the control circuit 9
It outputs a signal indicating the E or REV mode, and this signal is applied to the control circuit 4 through the AND gate 6 and the OR gate 11. In response to this, the control circuit 4 sends a control signal CTL for setting the CUE or REV mode to a predetermined circuit. When the CUE or REV button is released, the terminal 2 becomes "L" (low level),
The original PB mode is set.

Next, assume that the FF or REW mode is set, the "H" signal is applied to the terminal 3, and the AND gates 7 and 8 are opened. In this state, CUE
Alternatively, when the REV button is pressed, a signal of “H” is applied to the terminal 2, and this signal drives the operation control circuit 10 through the AND gate 7. As a result, the control circuit 10
Outputs a signal indicating the CUE or REV mode,
This signal is applied to the control circuit 4 through the AND gate 8 and the OR gate 11. In response to this, the control circuit 4 sends a control signal CTL for setting the CUE or REV mode to a predetermined circuit. CUE or REV
When the button is released, terminal 2 goes to "L" (low level)
Then, the original FF or REW mode is set.
