Abstract
Abstract A data acquisition laser scanner system. The system includes a laser scanner module and a data acquisition terminal. The data acquisition terminal comprises a housing, manual input means to input data therein, display means, and means for storing electrical signals. The module comprises a housing having a window, a source of laser light, a mechanism for sweeping the laser beam within the housing to produce a scan pattern comprising at least one line, a reflective beam folding system for projecting the pattern out of the window and onto an object, such as a bar code, and a system for receiving light reflected off the object to convert the reflected light into electrical output signals indicative thereof. The module also includes a connector for releasable securement to a mating connector forming a portion of the data acquisition terminal for mounting the module thereon and carrying the electrical output signals thereto.
