3. MECHANISM AND OPERAT I ON
The printer roughly consists of six blocks - a frame, X-Oir ection drive, Y-direction drive, pen dr ive
mechanism,
co lo r ch a.ngc mechanism, and pen take-o-ut mechanism sections. An explanation of these
blocks will be given below.
1. F
rame Sect i on
111e frame section has a side plate (r ight ), side plate (left) , holding plate, and paper guide. The
various mechanis
ms arc mou nted both inside and outs ide. The lower edge of the fr ame is bent in the
shape
of th e Jetter Lan d acts as a mountingleg.
2. X Dr i ve Mechan i sm Section

The reduction ratio between the stepping motor and bobbin gear is I :9.01 , and for each stepping
motor pulse (18°/ 360 ), the slider unit, that is, penXdirection movement, is 0.2mm. The motive
power
ls transmitted to the bobbin gear and slider unit by a wire, and the wire tension is main-
t;iined by a coil spring.
3. Y Drive Mechanism (Paper Feed Mechanism) Section
The Y·direction drive mechanism consists of the Y stepping motor , idl e gear, rubber roller uni t, paper
holding roller (fight) and paper holding roller (left). The reduction ratio between the Y stepping
motor (called the Y mot or below) and rubber r olle r gea r is l :7.8 6. As is the case wi ththeXdir ec-
tion, the rubber roller movement per pulse of the Y motor, that is , the Y diteclion movement
quantity of the recording paper,
is 0.2mm.

4. Pen DriveMechani sm Section
The pen drive mechanism, namely the pen up·down mechanism, comprises a self-holding type
electromagnet,
eject ion lev er, roller lever, and baU-point pens. Pen up and down directions are as
shown below.
• Pen-up State
The pen retracts when the elec tr om agnet is enc rg ized for 5 ms against the actuator spring, and
held by a permanent magnet e
ve n after the current is cut off after the initial 5ms.

From its pen-up state the pen descends when a current is impressed to t he electromagnet for 5
ms in an opposite direction to that used for pen retraction. After 5ms, the pen-down state will
be main!ained by !he actuator spr in g force.
5. Co l or Change Mechani sm Section
6
The color ch ange mechanism sect io n consists of the X-direction d ri ve mechanism, a pen holder and
holder stopper,
both in !he slider unit, and projeccions inside the holding plates. The operating
principles are explained below.

To operate the color change mechanism, first, t he slider is moved to the area a·l in Figure 6 (45
pulses to the left from the
or igin). Then, the holder stopper in the sl ider contacts the projection on
the holding plate, and the wedge section of the holder stopper slips out of the pen holde r, which
frees
it to ro tate. Next, by repeating the movement of the X motor for 30 pulses each in direction
A and
to the left, the pen (I) in Figure 5 changes to pen (2). The spring moves the holder stopper to
th e right until it returns to the or igin. If then enters the pen ho ld er groove. The pen holde is then
fixed,
an d printing is rea dy.
6. Pen Ejection Mechanism
Th e pen ejection mechanism c-onsists <.>tily of !he pen ejection lever 11131 is mounted on the side plate
(r ight). The slider unit is moved fully to the side plate (ri gh t) and is stopped ill order to change the
pen. Push the pen ejection lever towards you, and
th e pen w ill eject.
