PERATING PRINCIPLES General Description

.1 General Description

is chapter describes operating principles of the transparency unit (TPU) for pression 1640XL.

e basic scanning operation of the unit is designed the same way as the TPU

r GT-12000. That is, scanning operation is carried out with the document ed on the document glass and the lamp (light source) moving in

nchronization with the CR mechanism on the scanner side.

mentioned in Chapter 1, this unit, compared with that for GT-12000, has

me parts modified and does not use some other parts to enhance light aracteristics. However, this TPU is basically the same in operating principles

that for GT-12000.

1.1 Mechanism Operatione CR is driven by the torque sent from the CR motor assembly in the

llowing order:

Torque is sent to the drive pulley via the motor belt.

The torque is then transmitted to the transfer pulleys on the right and left base frame ends via the transfer belt which engages with the shaft for the

drive pulley. The CR belts, linking the transfer pulleys and corresponding

driven pulleys, are tightened up in the direction in which the CR moves.

The torque transmitted to the transfer pulleys is finally sent to the CR belts

to move the CR attached to the CR belts.

PERATING PRINCIPLES General Description

1.2 Electrical Circuit Operatione electrical circuit of this unit is composed of the control circuit and the

erter circuit.

e control circuit controls the CR motor driven by the power supply voltage

m the scanner side, and manages interface of signals with the scanner. The

ver open sensor, directly attached on the control board, monitors open/close

tus of the unit. The sensor uses a photo-interrupter sensor. However, it has

ob attached to its flag, and as the bob moves in accordance with open/close

otion of the unit, the sensor detects it as a change in flag condition.

e inverter circuit, incorporated on the CR together with the lamp, converts

wer supply voltage from the scanner into AC voltage for use to light the lamp

enon gas cold cathode fluorescent lamp) built in the CR.
