And 30 will stop all operations currently in progress and prepare for continuous playback mode. The next time the play button is actuated, the play operation will be started in the procedure specified by the logic circuit 40. Such a regenerating operation is to be continuously performed by the procedure of the first, second, third, first deck and the like. As shown, switches SW10, S
W20 and SW30 sense the loading of the cassette tape in each VCR deck, and AND sensors 13, 23
And 33 sense the end-of-play status of the tape loaded in each VCR deck, and the sensed signal is provided to each corresponding microprocessor.

0, R-out 20 and R-out 30.

When the logic circuit 40 designates any one VCR deck to be operated in the reproduction mode, the logic circuit 40
Is the R- of the specified VCR deck microprocessor
It provides a high level R-in signal at the in input pot. Such R-in signals include R-in10, R-in20 and R-in30 as shown in FIG. 5 as indicating a reproduction start signal for reproducing the designated VCR deck. In response to the R-in signal, the microprocessor reactivates the designated VCR deck and provides a high level PB signal to the logic circuit 40 through the PB output pot. Such a PB signal is a signal indicating that the specified VCR deck is currently operating in the reproduction mode. This signal is PB as shown in FIG.

In such a continuous reproduction mode, according to the present invention, the rewind mode is automatically performed each time each VCR deck completes the reproduction operation, or an eject button (not shown) provided separately for each VCR deck. The tape rewound by (No.) can be taken out from the VCR deck and the tape can be replaced.

Further, in the present invention, during the continuous reproduction operation, the absence of the reproduction signal having no information recorded on the tape is detected by the microprocessor for a preset time, for example, about 5 seconds, and is preset again. Time, eg V for about 5 seconds
This was done by operating the CR deck in high speed CUE mode and looking for the prerecorded signal in the tape. When the reproduction signal is not detected by this method, the microprocessor judges that there is no information recorded on the tape and outputs the R-out signal which is the reproduction completion signal. The reproduction signal can be detected by detecting a control signal generated from a control track of the tape or a vertical synchronizing signal in the reproduction signal as is known in the art.

Such a feature is possible by programming the ROM which is a memory device built in the microprocessor.

FIG. 5 shows a logic circuit 40 that specifies the procedure of the VCR deck playback operation.

The logic circuit 40 includes a large number of logic elements and is divided into three procedure designating parts, each of which corresponds to the corresponding V-signal based on the output signal from each microprocessor.
Specify the operation procedure of the CR deck. Logic circuit for this
The 40 actuation signals are provided by logic elements. PB10 + P
B20 + PB30 signals are PB10, PB20 and PB3
It means a logical sum (0R) of 0. Also, in the figure, the PLAY signal means a specific high-level 1-bit signal in the n-bit reproduction mode signal generated when the reproduction button is operated. The process for specifying the initial operation for each VCR deck is as follows. Continuous playback selection switch R-SW
Is activated and the play button is turned on, the R-in 10 signal is first provided to the microprocessor 10 of the first deck 110 from the logic circuit 40. If the cassette tape is not loaded in the first deck 110, the process of applying the R-in 20 signal to the microprocessor 20 of the second deck 120 is continued. When any one of the VCR decks is operating in the play mode, the logic circuit 40 does not output any R-in signal.

When the continuous reproduction selection switch R-SW and the reproduction button are operated, the initial operation of the first deck 110 was such that none of the VCR decks operated in the reproduction mode, as shown in A of FIG. Indicates (PB10 + PB20 +
It is designated by the logical product of the complementary signal of PB30 (usually, the complementary signal or the low level signal is displayed in a bar at the upper end) and the PLAY signal.

Since the second deck 120 can be operated only when there is no cassette tape in the first deck 110, the initial operation of the second deck 120 is the PLAY signal, as shown in FIG. 5B. (PB10 + PB20 + PB3
It is designated by the logical product of the complementary signal of 0) and the complementary signal of CST10 indicating that there is no cassette tape in the first deck 110. Similarly, in the initial operation of the third deck 130, the PLAY signal and (PB10
+ PB20 + PB30) complementary signal and CST
It is designated by a logical product of the complementary signal of the complementary signal of 10 and the complementary signal of the complementary signal of CST 20.

Upon completion of the regenerating operation of the first deck, the next operating procedure is designated for starting the next ranked deck in the replay mode.

When the microprocessor 10 determines that the reproduction operation of the first deck 110 is completed, the microprocessor transmits the R-out 10 signal to the logic circuit 40 to operate the first deck in the rewind mode. As a result, the logic circuit 40
Provides the R-in 20 signal to the microprocessor 20 of the second deck 120 so that the second deck can perform the reproducing operation.

Similarly, when the second deck 120 has completed playback, the second microprocessor 20 will generate an R-out 20 signal and the logic circuit 40 will provide the R-in 30 signal to the next-ranked microprocessor. To do.

If the cassette tape is not loaded in the second deck 120, it is determined whether the third deck 130 is operable. This is the R-out10 signal and CS
Specified as a logical product with T20.

Similarly, if the third deck 130 has completed operation or does not have a cassette tape, in the case of the triple deck VCR system in this embodiment, the next operation procedure is the R- in 30 by the logic circuit 40. Proceed to the first deck 110 or Ro by providing a signal
The logical product of the ut20 the CST3 0 proceeds to the first deck. This process is repeated until the switch R-SW is turned off. 6 and 8 show flow charts of the continuous reproduction method according to the embodiment of the present invention.

At step F1, the continuous reproduction selection switch RS
Whether or not W can be operated is determined. When the switch R-SW is actuated, step F2 is proceeded to, where it is judged whether or not each eject button provided on each VCR deck is actuated. When the eject button is activated, the process proceeds to step F3. In step F3, the currently loaded tape or the tape that has been played back can be removed or replaced with a new tape.

If it is not in the eject mode, it is judged in step F4 whether or not the specific VCR deck is operating in the reproducing mode. If not, it is determined in step F5 whether the play button has been activated. Stage F4 and Stage F5
If any of the determination results in step 1 is YES, the process proceeds to step F6.

At this stage F6, the VCR deck designated by the reproduction logic circuit 40 starts the reproduction operation.

At step F7, it is judged whether or not the regeneration operation is completed. If the determination result is YES, the process proceeds to step F12 associated with the label "B" in FIG. 7, and if the determination result is NO, the process proceeds to step F8.

At step F8, it is judged whether or not there is an unrecorded area on the video cassette tape. If the control signal or the V-sync signal is not detected for a preset time, for example, 5 seconds, the label "C" of FIG. 7 is passed to step F9 to operate the VCR deck in the CUE mode. If a control signal or V-sync signal is detected within that time, the label "A" is returned to step F1. In step F10, the presence or absence of the control signal or the V-sync signal is detected again while proceeding in the CUE mode. If step F10 even control signal or V-sync signal is not detected, the process proceeds to step F12.

If the control signal or the V-sync signal is detected within the time, the process proceeds to step F11 to change the current CUE mode to the reproduction mode and then label "A".
To return to step F1.

In step F12, the R-out signal is provided to the logic circuit 40, which in turn operates the VCR.
Specify the deck. The deck thus designated performs the above-mentioned steps and the steps described below.

Thereafter, in step F15, the VC whose reproduction is completed is completed.
R deck automatically performs rewind mode, step F16
Then, it is determined whether or not such a rewinding operation has been completed.

In step F16, if the continuous playback mode is canceled or the rewind button is turned on, the process proceeds to label "A".

If the decision result in the step F5 is NO,
In step F13, it is determined whether the VCR deck operates in the rewind mode. If the determination result is NO, the process proceeds to step F14.

In step F14, it is determined whether the rewind button has been turned on.

If the decision result in step F13 or step F14 is YES, the process advances to step F15 accompanying the label "D" in FIG. 7, and if the result is NO, the process advances to label "A". this
So when the first VCR deck completes the playback operation,
