8.
Limit sensor.
In order to prevent the bobbin from being excessively wound when automatically winding bobbin, the
sensor monitors during bobbin winding and detects that the bobbin is wound more than the specified
amount. Then bobbin winding automatically stops.
9.
Pattern selection.
Direct selection of Patterns through a transparent touch panel and indication of selected pattern on
LCD.
10.
Number of patterns
Practical patterns 87, Continuous patterns 58, Adherence one point 34, One point 167, Lettering
characters 4 fonts 450, large pattern 44.
11.
Constant-position needle bar stopper.
The machine stops with its needle up or down using the synchronizer shield plate and detector
(photo-interrupter) mounted on the main shaft.
When the thread trimming presser is raised, when the embroidering device is used or when the
bobbin is to be wound, the machine stops with its needle up. In a case other than those described
above, the machine stops with its needle down.
12.
Prevention of wrong-setting of needle.
It is designed so as not to insert the needle in the wrong direction.
13.
Operation guide.
How to operate the sewing machine, advice and how to sew are indicated on LCD.
14.
Prevention of overheat of motor.
If the sewing machine motor shaft is locked, the power supplied to the motor is automatically turned
OFF after 1 to 1.5 seconds.
If the motor becomes extraordinarily hot in such cases as the sewing machine continuously runs at
high speed, the thermal sensor built in the motor detects and stops the machine operation. (The
power is turned ON again after the motor has cooled down.)
15.
Automatic bobbin winder.
When performing the embroidering, exclusive bobbin thread can be wound to bobbin without
removing bobbin. In addition, after bobbin winding, threading to bobbin thread tension spring and
thread cutting are performed. Then sewing can continue.

A large scale and original circuit is necessary for the computer sewing machine. The circuit is built in
the IC, which is the exclusive one produced for this model only.
