DESCRIPTION:
BRIEF SUMMARY
TECHNICAL FIELD
The present invention relates to methods and apparatuses utilizing control strips for managing the developer or the like in relation to automated print and development apparatuses, where photosensitive substances are used for printing negative images.
BACKGROUND ART
Management of the developer in automated print and development apparatuses is conventionally conducted based on the processing of what is called a control strip, which is a photographic printing paper.
The control strip is a photographic printing paper where an emulsion is spread, and is located in the dark inside of a dark chamber called a control strip holder, which is provided with a shielding port exclusively for using with automated print and development apparatus. To the control strip's leading end that protrudes from the control strip holder and that is exposed is attached a special control-strip-leader with splice tape, and the leader is then installed in the automated print and development apparatus for the processing.
FIG. 1 illustrates in perspective view a conventional control strip holder. The control strip 1 is inserted in the control strip holder 2. FIG. 2 shows the sectional view of a conventional control strip holder and shows the manner in which the control strip loaded in the control strip holder of FIG. 1 is being drawn out.
The control strip 1 is attached to the leader 3 with splice tapes 4 and 5. By pulling at the leader 3, the control strip is cleared of the shielded port of the control strip holder.
While the shielded port of a conventional control strip holder is formed of oppositely placed velvets as shown in FIGS. 1 and 2, and the control strip is inserted through the gap in the velvets, in practice putting the control strip through the gap had been a difficult task.
In addition, owing to the fact that the force required for pulling the control strip once the said control strip is loaded in the control strip holder is also as large as roughly 1 kg, the control strip had been drawn from the automated print and development apparatus with a force supplying means by pulling a leader, which was fixed to the control strip with tapes.
Nevertheless, this process of fixing a control strip leader had not been an easy, and it is thus desired to perform the control strip processing in a much simplified manner. The present invention therefore has the objective of simplifying the control strip processing by the utilization of a new construction for the control strip holder.
DISCLOSURE OF THE INVENTION
In order to solve the above problem, a control strip holder whereof the shielding door can be opened or closed by means of externally executed commands to open or close is positioned on the exposure station of an automated print and development apparatus that is provided with the means of executing commands for opening and closing the shielding door of the control strip holder, and having automatically drawn from the control strip holder, the control strip is adhered on the exposure station and conveyed to the development processing section. Drawing of the control strip is to be accomplished by utilizing the suction force of exposure station. In that manner, the structure of the control strip is devised so as the suction strength of the exposure station is amply available for the drawing of the control strip, and thus the drawing of the control strip is made possible by the suction force of the exposure station.
The operation of the present inventive apparatus is described as follows. Having arranged a control strip holder that has a shielded opening and a control strip, the shielded door of the control strip holder is opened inside of a dark chamber (or a darkroom), and the shielded door is then closed having inserted one sheet of control strip in the control strip holder.
The control strip holder taken out from the dark chamber (or the darkroom) is then positioned, after opening the shielded door of the automated print and development apparatus, on the exposure station, and the shielded door of the automated p
