BASIC OPERATION 12 February 1992

4. BASIC OPERATION

[B]

[A]

Y

X

There are resistors [A] (carbon sheets) in the positioning sheet aligned in the
X and Y directions. When part of the positioning sheet is pressed with the
stylus pen, voltage corresponding to the combination of the resistors is
detected.

The detected data is transmitted to the copier as the coordinate position. This
detection method also applie s t o the m od e sele ctio n pa ds [B ].

XL

A/D 8 bit

The positioning sheets consists of two carbo n she et s for X an d Y dir e ctio n,
and insulator dots located in-between the two carbo n sheets.

When the positoning sheet is pressed with the stylus pen, the switch in the
stylus pen turns on and starts the detection of the coordinate point. Also, the
upper carbon sheet contacts the lower carbon sheet at the coordinate point.
Therefore, the voltage correspondi ng to the coordinate point is sent to the
A/D converter.

Coordinate Point in X Direction:

The voltage of the coordinate point in the X direction is sent to the A/D
converter through the Y line as the switching transistor T1 is turned ON and
the voltage is applied to the X line. At this time, the switching transistor T2
should be OFF.

Coordinate Point in Y Direction:

By changing the ON/OFF position of the switching transistors T1 and T2, the
voltage of the coordinate point in the Y direction is sent to the A/D converter
through the X line.

6. ERROR DETECTION

6.1 INITIAL ERROR

Short circuit and disconnection of the resistors in the positio ning sheet is
checked when the power is turned ON . If an er ro r is foun d an d coo r din at e
data input is made with the stylus pen, the buzzer sounds for five seconds
and the coordinate position at that time is not transmitted to the copier.

6.2 PARITY ERROR (Communication Error)

When data transmitted from the editor or copier has on error, the service call
"SC94" is lit on the copier control panel.
