Abstract

A printing device transfers slide dependent information onto glass surfaces such as a glass slide for holding a medical specimen. A single slide is transferred from a storage section, passing under a thermal print head. The thermal print head defines and transfers an image from an ink media onto the slide as the slide passes across the print head. The print head utilizes pixel like heating elements to apply the desired image. The ink media moves in tandem with the motion of the slide, presenting a continuously fresh section of ink between the print head and the slide throughout the printing process. The information on the slide should be both human and machine readable to reduce any chances of misidentification of the specimen as to the patient. The ink media is endures any chemical processes and handling encountered throughout the expected life of the slide.

Dependent claims

A method of transferring information onto surfaces of objects comprising:

inputting information into an input device, the input device transforming the information into an image for storage in a printing memory as a stored image;
positioning one or more glass objects in an object storage section by a printing device;
removing one glass object from the storage location into a glass object carrier of the printing device;
indexing the glass object in the carrier to initialize the printing;
transporting the object to a first position under a print head of a printing means for transferring such information to the object;
positioning an ink media tape from a driven feeder between the print head and the glass object;
moving the print head and glass object together to cause the tape to contact the glass object in the carrier;
heating, as required, at least one pixel element in a predetermined manner in the print head to print a row from the stored image by a thermal process to cause an inked media to transfer onto the object as determined by the stored image;
advancing the tape and indexing the object to a next print row and repeating the steps from positioning the tape to transfer the desired information to the object;
after printing the last row of data, separating the print head and object to a non-contact position;
transporting the glass object by the carrier to an output section;
removing the glass object wherein the object is mechanically removed into the output section;
and
repeating said method as many times as necessary as determined by the operator.

11 more elements

A printing device for attaching information to a glass like object, the printing device comprising:

an input/interface means for transferring information to the printing device;
a processing means for receiving the information from the input/interface means and transforming the information into an image for printing, the image being stored in a memory of the processing means;
a control means for the input/interface means and the processing means;
a storage section for the objects, the storage section being an integral part of the printing device;
a shuttle having a carrier for removing one of the objects from the storage section in a controlled manner and indexing the object for printing, the shuttle moving the object so indexed to a first print position;
a printing section, the printing section comprising:
a tape feeder, the taper feeder being driven by the processing means, a tape from the tape feeder being positioned for printing in close proximity to the glass like object in the first print position;
a print head, the print head having a plurality of heating pixel elements in a row for printing the stored image by a thermal process to cause an inked media to transfer onto the object as determined by the stored image, after printing data in the first print position, the print head and tape are advanced to the next printing position, this is repeated until the stored image is printed on the glass like object, after printing the stored image, the print head and glass like object separate to a non-contact position, and the carrier moves the glass like object therefrom;
and
an output section, the object with a printed image thereon is moved to the output section, after which another glass like object is removed from the storage section by the carrier if so required and the process repeated as necessary.
