Line Source Compartment Mechanics - Philips CARDIOMD Service Manual

12.3.4.1 Line Source Compartment Mechanics

Line Source House Motion
Inside the line source compartment are mounted two rails supporting two slide bearings. The line
source housing is mounted on top of the slide bearings (see Figure 12.13 on page 12-16) and can
thus be translated from one end of the line source compartment to the other.
Figure 12.14 gives a more detailed inside view of the line source housing.

Figure 12.14 Components involved in line source motion
The motion controller controls the servo motor driving the line source in its housing. The torque
from the servo motor is transferred via a belt to the Acme screw (see Figure 12.13), which is
mounted underneath the toothbar.
Note. Carefully route the encoder cable to prevent interference with the line source position
indicator arm.
