A method and apparatus for inspecting the quality of transparent protective overlays. The inspection method and apparatus enables accurate inspection of formed transparent protective overlays and enables implementation of more quantitative control of transparent protective overlay quality. Such method and apparatus automatically and accurately inspects the quality of transparent protective overlays placed on substrate surfaces to determine whether the transparent protective overlay formed to protect information such as images, text, or symbols recorded on the surface of a card-type or other easily portable information-recorded medium is of acceptable quality.

Method and apparatus for inspecting the quality of transparent

An image-forming apparatus based on an observation of a coincidence of a circular length and a chord length. A precise transfer of the image on a transfer object is accomplished without breaking of the image by maintaining a fixed attitude of the object; by allowing the object's movement at heating and pressing of the transfer film and the object; and by preventing an adhesive layer of the film from adhering to clamps for the object and a rubber. Transfer of an accurate image from the film onto the transfer object by the image transfer apparatus is accomplished by a movable stage which is movable in a longitudinal direction of the film to locate a transfer object to be pressed and heated via a transfer film by a heating roller and a holding apparatus which is located on or on a side of the stage and which is relatively moved along with the stage while partially holding the transfer object.

Image-forming apparatus

An image transfer device for transferring a clear image to a transfer object includes transport device for a transferring film, an image writing device for transferring ink from a transfer ribbon onto the film by a thermal head, a stage for fixing a transfer object, a guiding means for a inked image of the film onto the object on the stage, a transfer roller for transferring the inked image to the object, and a peel roller disposed in the vicinity of the transfer roller for peeling the transferred film from the object.

Image transfer device

Apparatus for producing an information recording card

A thermal head for a thermal printer or a thermal transfer printer wherein a substrate linearly formed with a plurality of heating elements and a control substrate for controlling generation of heat of the heating elements are mounted on different surfaces of a heat sink having a certain angle therebetween, whereby the printing mechanism can be simplified and compact in construction. Particularly, where the thermal head is applied to a multicolor recording apparatus, it is possible to increase the recording speed and miniaturize the apparatus.
