Abstract
A sheet of film, for use in recording the results of non-invasive medical tests, is indexed relative to a lens and shutter assembly to permit the serial formation of multiple images on the film. The indexing is accomplished through the use of a transport mechanism which may be independently moved in two mutually transverse directions.
Claims11
A transport mechanism for a recording medium comprising:
- means for receiving and holding a recording medium;
- means supporting said receiving means for linear motion in a first direction;
- means mounting said supporting means for linear motion in a second direction transverse to said first direction;
- a first stationary drive motor;
- drive belt means, said drive belt means being affixed to said receiving means;
- idler means for supporting said drive belt means at a point displaced in a first direction beyond a first limit of motion of said receiving means, said idler means being mounted from said supporting means for movement therewith;
- means for engaging and driving said drive belt means;
- a rotatable spline shaft, said spline shaft being driven by said first stationary motor, said drive belt means engaging means being mounted on said spline shaft for rotation therewith, said engaging means also being moveable in said second direction on said spline shaft;
- means supporting said spline shaft at points displaced in said second direction beyond the opposite limits of motion of said supporting means in said second direction;
- and
- means including a second stationary motor for imparting motion to said supporting means in the second direction independently of movement of said receiving means in said first direction.

A transport mechanism for a recording medium comprising:
- a film cassette holder, said holder having an access opening in a first side thereof;
- frame means extending about said holder adjacent to said access opening;
- guide bearing means affixed to and extending from said holder;
- means engaging said guide bearing means for supporting said holder for linear motion in a first direction;
- means mounting said supporting means for linear motion in a second direction transverse to said first direction;
- means including a first stationary motor for imparting motion to said holder in said first direction independent of movement of said supporting means in said second direction;
- and
- means including a second stationary motor for imparting motion to said supporting means in said second direction independently of movement of said holder in said first direction;
- housing means, said holder and said supporting, mounting and motion imparting means being positioned within said housing means, said housing means including:
- plate means for cooperating with said frame means to establish a light-tight seal about said holder access opening;
- and
- means defining a guide slot adjacent said plate means, said guide bearing means being received in said guide slot to establish said light-tight seal.
