This
tape
reader
is
designed
for
use
in
reading
the
punched
tape
which
is
used
for
NC machine,
computer,
and
the
like.
The
stepping
motor
manufactured
by
this
company
is
adopted
for
the tape
feed.
Noise
accompanying
the
tape
feed is
almost
negligible.

Intermittent feed
The input signal causes the feed speed to vary over the
range of 0 to 270 char/sec. The character advances by one
at the signal level "1."" (The "'l'' stays on until the data
strobe signal starts to rise.) The tape is not fed at the
Signal level "0." Let "1" be +5 V TTL level (+2.4 to +5 V),
and "0," on Vv.

The feed speed is 270 characters per second, When the

Data Output Signal (Fig. 3)
The data output signal is delivered at the IC level from 1 to 8
channels. The signal is "1'' when the hole is present, ''0" when the
hole is absent, and 10 for fan-out. The stopping position of this
tape reader is at OFF character. The phototransistor signal is
stored into the data memory circuit incorporated in the tape reader
as a data output signal about 120 us before the data strobe signal
is generated. In this way, the pre-phototransistor signal can be
maintained before the operation is stopped.

Erratic Operation Detection System
This tape reader delivers the error signal when the stepping motor
is performing an erratic operation which is caused by the tape
tension under the load of more than 300 g or by some electrical
trouble. Under this condition, PTR ERROR lamp lights. In this
case, all the data output signals turn to '"'0."!
Error signal level "0": The tape reader is normally functioning.
Error signal level "1": The erratic operation of the tape reader is
detected, the lamp lights, and the data
output signals turn to "0."
Once the stepping motor performs erratic operation, the error signal,
lamp, and all the data output signals maintain the status of erratic
operation. The tape reader can be restarted by resetting. Press
the reset pushbutton, and make sure that PTR ERROR lamp goes off.

Make wiring connections according to the pin arrangement of power
and signal connectors as shown in Fig. 7. When making wiring con-
nections, pay attention to the Note below.
Note: Run the wire through the shortest distance. Use care so as
to avoid noise interference. The sectional area of the wire
used shall be greater than 0.5 mm.

ME—-U4 10 boy Li
(b) Do not expose the tape to the sunlight or bring it near a
heat source. Use care so as not to let water or oil be
splashed onto the tape. (If this care is not taken, light
transparency will become excessively high.)
(c) MKC CF SRWEIKL TREY. (CF -FRHBORY, PA BWOKRD, BR
(ok SHUT FS BABEL Ze D LET)
Do not rub the tape strongly. (If this care is not taken,
the
tape
will
become
undurable
or
fluffed,
or
cause
dust
accumulation due to static generated by friction.)
(d) Si BABLEAWELIMLTTFEW,

Cleaning : Deposition of dust or tape chips on the tape surface
May cause misreading. Clean the tape surface and
the glass sheet of the LED case with a soft brush or
suchlike from time to time. If the dust deposit is
obstinate, remove the LED case so that access for
cleaning is gained to the tape surface and the glass
sheet of the LED case. .

If the tape reader misreads the tape or develops some trouble,
check it using Table 1, a troubleshooting chart, as a guide.
At the same time, immediately inform your dealer of the

Inspection
The erratic operation detector is free of wear as it is
of non-contact type. Malfunction is caused when dust or
tape chips are deposited on the light emitter and receptor
of the photocoupler. Remove the case cover, and clean the
light emitter and receptor with an air brush or suchlike
from time to time.

Troubleshooting
When PTR ERROR lamp abnormally lights as mentioned in
Table 1, and the photocoupler is suspected to be the cause,
use the following procedure to check and clean the erratic
operation detector.
Obtain (1) dual trace oscilloscope Do not tamper with the

Waveform Inspection: Operate the tape reader at the
the maximum speed in either forward or reverse di-
rection. Observe the waveforms which are obtained
by synchronizing signals from check terminals E and
PS of the printed circuit board on the dual trace
synchroscope. Refer to Fig. 13 below for the
positions of check terminals.
