4.4 DIRECT MUSIC SEARCH
For direct search, the tape is first rewound comple-
tely in RE\{ mode. \ryith one of the search keys de-
pressed, the tape is then fast-forwarded to the be-
ginning of the program desired (the intervals be-
tween programs are counted during FF mode).
When the beginning of the wanted program is
reached, the tape is set in the STANDBY mode.
Depressing the PLAY key allows the program to
start. In this way, the desired progxam is automati-
cally located for playback by depressing the pro-
gram No. key.
The direct music search mode allows desired pro-
grams to be played back in a desired sequence re-
gardless of the order in which the proglams lvere
originally recorded (for the first program to be
played back, tape is rewound until the beginning of
the tape is reached; from the second progmm on-
ward, direct search takes place). Moreover, the
sarne prograrn can be played back as many times as
the prognm No. key is repeatedly depressed (up to
16 times). When used for copying, this mode en-
ables the desired number of progxams on the o-
riginal tape to be dubbed in any desired sequence.
During copying, the non-recorded sections between
the programs being dubbed are automatically ad-
justed for a uniform interval (automatic random
editing).
4.5 MODE CHANGE IN THE MECHANICAL
SECTION
The mode selection for the mechanical section is
controlled by the output (pins 37 through 40)
from the microcomputer (IC 501) corresponding
to the key input. The output from the microcom-
puter turns on and off SOL 1 and SOL 2 of the
mechanical section, which trigger mode changes
with the po\Mer assist mechanism using the rotar5l
power of the capstan motor. The mechanical sec-
tion changes its mode as shown in the Fig. 4-13,
and this always via the stop mode. The timing
chart in Fig. 4-15 shows the control signals for
different modes sent from the microcomputer.
