Reel motor MOTl? The enclosure of the input terminals Ai, Pi and the output terminals AO, BO of the decorative collector circuit 03 is exposed through the first frame.

a l A reference voltage is applied to the front terminal RK, and the reel motor MOTI changes the rotational speed in proportion to this input voltage. The capstan motor C4 controlled by the capstan motor MOT2'i performs the first operation in the same manner as the above-mentioned collector circuit C3. Since the terminal R of this Shumen Kai Tsumugi 04 is grounded,
The motor MOT2 rotates at a constant rotation speed of c.

PLNI is an electromagnetic solenoid that drives m & P to load and eject the cassette.
An electromagnetic solenoid is used to interlock and drive the mechanism for approaching and separating the cicada air chi 711 in the L N 2 ukft air head bag and the mechanism for approaching and separating from the pinch roller cab.

There are 18 ways to get to E.

The outputs AUTO- and r are signals (low active) that inform that the top-out selection is in progress, and the light-emitting diode LL is turned on by this signal. FF and REV are 2H2 signals indicating fast forwarding and rewinding, and the light emitting diode L2. L3'! Each of them works secretly. Travel A1 and Travel B indicate the running direction of the magnetic tape 4 as shown in Figure 4. In travel A, the light emitting diode L4 lights up, and in travel B, the light emitting diode L lights up.

However, if the magnetic change caused by the tape running through the magnetic head is obtained by adding it to the electrical signal, and if this effect is increased with an equalizer amplifier, it will be replaced as a t-force or noise. be born.

Each music issue is input to the processing circuit 14 at a light level tV. Reel rotation detection number B is used to check whether the rice feeder, in which the key man-powered steel cylinder 29 is operated, is moving as expected. Each issue of music is used to detect whether or not it is stored inside the magnetic tape, for example, when the /M raw machine 3 is powered on in a cassette tape recording, which is essential for detecting between songs. Then, the rising waveform of the applied %L source is divided into two parts, and the processing part M1 is reset by the delayed output.

The time chart of the operation in the loading state where the cassette tape recorder/player 3 is powered on and the tape is loaded after 7'C is shown in Figure 3. M.O.
