S14, a reception control signal is sent to receive the tra?ic
information broadcast. Control then proceeds to step S15.
Step S15 loops back to itself until ISR switch 8 is activated
again. When ISR switch 8 is reactivated, control proceeds to
step S16 where the operating mode, stored in RAM at Step
outputted and the function of the special playback mode
continues. If the ?mction of the special playback mode is
completed before the traffic information broadcast is ?n
ished, the current operating mode switches to normal play
back mode. The switch to normal playback mode is per
formed internally by tape deck 20 by a process external to
the control flow of FIG. 2. The switch to normal playback is
detected in step S17. Tape deck 20 is put in pause mode in
step S18 and the tra?ic information broadcast continued in
steps S19 and S20. Control loops at step S21 until ISR
switch 8 is reactivated, indicating the user wishes to switch
back to tape deck 20. Since the special playback mode was
continued during the tra?ic information broadcast, the tape
will begin playing at the point where it would have been
S11, is activated.
When the current operating mode is not the radio recep
tion mode in step S13, control proceeds to step S17. Step
S17 branches to step S18 if the current operating mode is the
normal tape playback mode. In step S18, a control signal is
sent to put tape deck 20 in a playback pause mode which
stops the tape then playing. Control then proceeds to step
S19, where a reception control signal is sent to receive the
tra?ic information broadcast. Control then proceeds to step
S20 where a selection control signal is sent to source
selection switch 5. The selection control signal causes
source selection switch 5 to connect radio output line 61 to
15
Referring to FIGS. 1 and 3, a block diagram of a second
embodiment of the invention, audio unit 150, is shown in
FIG. 3. The only difference between FIGS. 1 and 3 is that the
function of ISR switch 8 is replaced by an internal function
ampli?er input 64 causing the radio output to be ampli?ed
and output to speaker 7. Control proceeds to step S21. Step
S21 branches to step S16 if ISR switch 8 is reactivated or
loops back to itself if ISR switch 8 is off.
If the current operating mode at step S17 is not the normal
of a special radio tuner, called an ARI-type tuner 30,
described below. Elements that are identical to the ?rst
embodiment are given the same notation and the explanation
of their composition and operation are as described with
reference to FIG. 1.
In audio unit 150, radio tuner 10 of FIG. 1 is replaced by
ARI-type tuner 30. ARI-type tuner 30 is a radio tuner
tape playback mode, then control branches to step S22. For
example, if the current operating mode is a special playback
mode such as FF-APC or REW-APC, then control branches
to step S22. At step S22, the current special playback mode
is continued. Control then proceeds to step S23. At step S23,
a reception control signal is sent to receive the tra?ic
equipped to receive identi?cation signals, called DK signals.
DK signals indicate the presence of a special type of traffic
information broadcast. Control then proceeds to step S24,
information broadcast, or ARI broadcasts, which are made at
where a selection control signal is sent to source selection
switch 5 to connect ampli?er input 64 to radio output line 61.
Control then proceeds to step S25 which branches to step
S16 if ISR switch 8 is on, or to step S17 if ISR switch 8 is
a speci?ed frequency set internally in ARI-type tuner 30.
When a DK signal is detected by ARI-type tuner 30, a
control signal is sent to control circuit 9 to indicate the event.
This function replaces ISR switch 8 of the ?rst embodiment
of FIG. 1.
01f.
According to the embodiment of the present invention
described above, if the current mode at step S17 is not the
Referring to FIGS. 3 and 4, operation of control circuit 9
according to the second embodiment is as follows. The
operation sequence is identical to that described with refer
ence to FIG. 2, except that the radio reception mode is
invoked in response to a DK signal from ARI-type tuner 30
instead of an ISR signal from ISR switch 8. Both the signal
from ISR switch 8 and the DK signal are sent to control
circuit 9 in the respective embodiments. FIG. 4 is a How
chart which shows the operation of the control circuit from
the time a DK signal from an ARI broadcast is received.
The operation of the second embodiment is identical to
normal tape playback mode, then the current special play
back mode is continued. For example, if the special play
back mode is FF-APC or REW-APC, then tape deck 20
continues to fast-forward or rewind the tape as control
proceeds to step S23. At step S23, a reception control signal
is sent to receive the tra?ic information broadcast. Control
then proceeds to step S24. In step S24, a selection control
signal is sent to source selection switch 5 to connect radio
output line 61 to ampli?er input 64 causing the radio output
to be ampli?ed and output to speaker 7. Since the special
function is continued rather than paused at step S22, the tape
continues the special function while audio unit 100 outputs
the tra?ic information broadcast. Control then proceeds to
step S25. Step S25 branches to step S16 if ISR switch 8 is
on again. If ISR switch 8 is still off, control proceeds to step
S17.
In step S17, the current operating mode is checked again.
If the special playback mode has completed, the operating
mode will have switched to normal tape playback mode. For
example, if tape deck 20 has ?nished rewinding the tape, the
normal playback mode is automatically invoked. If the
normal playback mode is the current operating mode, step
S17 branches to step S18 where tape deck 20 is put in pause
mode. The tra?ic information broadcast continues to be
50
55
If ISR switch 8 is activated when tape deck 20 is in a
special playback mode, the traffic information broadcast is
that of the ?rst except for the replacement of the ISR signal
with the DK signal. According to the second embodiment, if
a DK signal is detected when tape deck 20 is in a special
playback mode, the tra?ic information broadcast is output
ted and the function of the special playback mode is con
tinued until completed. If the function of the special play
back mode is completed before the tra?ic information
broadcast is ?nished, the current operating mode switches to
normal playback mode. The switch to normal playback
mode is detected in step S37. Then tape deck 20 is put in
pause mode in step S38 and the tra?ic information broadcast
continued in steps S39 and S40. Then control loops at step
S41 until a new DK signal is received. Thus, when a new DK

control means connected to said tuner means and said
playback means, for pausing a scanning of said
recorded medium when said tuner means produces said
?rst output signal, said control means including means
for preparing for a further scanning of a selected
the role of the ISR signal from ISR switch 8.
According to the third embodiment of the invention, if a
TA signal is detected when tape deck 20 is in a special
playback mode, the traf?c information broadcast is output
ted and the function of the special playback mode continues.
If the function of the special playback mode is completed
before the traf?c information broadcast is ?nished, the
current operating mode switches to normal playback mode.
The switch to normal playback mode is detected in step S57.
Then tape deck 20 is put in pause mode in step S58 and the
tra?ic information broadcast continued in steps S59 and S60.
Then control loops at step S61 until a new TA signal is
received. Thus, when a new TA signal is received indicating
the traf?c information broadcast is over, the tape will play at
the point where it would have been after completion of the
portion of said recorded medium, said preparing being
continued under a predetermined state of said playback
means.
