Patent ID: 7702069

Claim:
An X-ray security inspection machine, comprising: a machine housing defining therewithin an X-ray tunnel for receiving an article to be inspected; a conveyor means for conveying the article through the tunnel; an X-ray source for irradiating the article within the tunnel; an X-ray detection means for detecting X-rays transmitted through the article, wherein the X-ray detection means comprises a photodetector array module actuatable between a first stowed configuration in which the photodetector array module occupies a region of the X-ray tunnel and a second deployed configuration in which the photodetector array module projects from the machine housing and the X-ray tunnel is substantially unobstructed by the photodetector array module; and an actuation means for translating the photodetector array module between the stowed and deployed configurations, wherein the actuation means comprises an extendable and retractable actuator arm coupled to the photodetector array module wherein the actuator arm is coupled to the photodetector array module via a pivoting arm extending across and slidingly coupled to the photodetector array module, such that rotational movement of the pivoting arm effected by the actuator arm is transformed into translational movement of the photodetector array module.
