General Information
Product Description
The JB-70 Dental X-Ray System is a state-of-the-art intra-oral x-ray machine. The
JB-70 consists of five components, as shown in Figure 1 Component Diagram: the
Control Unit, the Tubehead, the Articulating Arm, the Horizontal Arm and the Cone.
Control Unit The Control Unit provides for the input power connection and control of the Tubehead
and Operator Panel. It provides automatic line voltage compensation, kVp control and
exposure time control. The Control Unit consists of the mounting base and Operator
Panel.
Tubehead The Tubehead contains the x-ray tube, high voltage transformer, and Cone. The
Tubehead is shipped already assembled to the Articulating Arm.
Note: There is a small hole in the plastic handle covering the back of the
Tubehead. Under no circumstances should this hole be blocked as it provides an
air vent to allow the Tubehead oil to expand and contract as the unit is operated.
Articulating
Arm The Articulating Arm provides the articulation support for the Tubehead and the reach
and coverage of the Tubehead to the patient. The Articulating Arm allows smooth
movement for precise positioning and does not drift or vibrate when left in position.
Horizontal
Arm The Horizontal Arm helps provide the necessary reach for the JB-70. The Horizontal
Arm pivots smoothly around a shaft inserted in the top of the Control Unit. The
Horizontal Arm contains an access cover to connect the cable from the Horizontal
Arm to the Control Unit. The Horizontal Arm is available in two lengths, one that
provides a 76 inch reach and one that provides a 66 inch reach.
Cone The Cone establishes the distance from the x-
ray tube to the patient’s skin. It
provides positioning assistance and collimates the x-ray beam to within a defined
circle at its end. The JB-70 is shipped with the standard 8 inch Cone attached to the
Tubehead. A 12 inch Cone (30-A2033) can be ordered as an option.
