Description

[Detailed description of the invention] This invention runs a long photographic paper that has been printed and developed, that is, a long photographic print formed by connecting individual photographic prints. We inspect each photographic print one by one,
This invention relates to an improvement in an inspection device that places a mark on defective photographic prints to indicate the fact.

Traditionally, in photo labs, etc., long photographic paper that has been printed and developed is rolled into a roll. A long photographic print is guided and run on an inspection table of an inspection device, and the quality of each individual photographic print that makes up this long photographic print is judged, and necessary repairs such as reprinting are performed. For defective photographic prints, stop the long photographic prints, use a graphite pen, etc., to mark them accordingly, and then cut them out with an auto cutter to cut them out one by one. The auto selector was used to sort these into photo prints.

However, as mentioned above, when checking defective photographic prints using a graphite pen, etc., if this check is incomplete, the dirty photographic prints will not be sorted by the auto selector. Contaminants may be mixed into high-quality photographic prints, causing not only discomfort to customers but also a sense of distrust.Also, even if the check is complete, long photographic prints with areas marked with this check may When it is wound up, graphite transfers to other photographic prints, staining other good photographic prints or fading them, and causing detection errors when sorting by the auto selector, causing good and proper photographic prints. This has led to the uneconomical situation of sorting out defective products, or has caused defective photographic prints to be mixed in with non-defective products, resulting in the same result as in the case of defective products.

As a means to avoid these problems, methods such as attaching tape coated with graphite or tape made of a material that does not transmit infrared rays have been considered, but when considering the amount of work and time involved, this was by no means practical.

In view of the above-mentioned circumstances, the present invention was developed using a long photographic paper that has been printed and developed, that is, the individual photographic prints are connected, and the individual photographic prints are connected to each other. (a) An inspection device for inspecting the quality of each long photographic print with a cut mark applied thereon.a) Guides and runs the long photographic print, and during this time inspects each individual photograph. an inspection table for inspecting the quality of the print; b. a cut mark detector disposed on a long photo print that is guided and moved on the inspection table; and a cut mark detector that detects the cut mark when viewed from the direction in which the long photo print is moved. At the rear of the container, there is a punch hole puncher for punching defective photographic prints to indicate that they are defective photographic prints, and c. While the switch and the switch for transmitting the operation signal of the punch hole puncher and the switch for transmitting the above-mentioned travel start and travel continuation signal were maintained in the ON state, a medium-length photographic print was run, and the switch was turned OFF. The detection signal from the cut mark detector is used to stop the running of long photographic prints, and for defective photographic prints, a switch is turned on to indicate this, and a sign is placed to indicate this. It is made up of a long length of photographic paper that has been printed and developed, that is, a shape in which individual photographic prints are connected. Cut marks are placed between each individual photo print.Among the individual photo prints of long photo prints, defective individual photo prints that cannot be given to customers are given a cut mark to prevent transfer or fading. To automatically punch holes as markings without causing the above-mentioned inconveniences, difficulties, shortcomings, and defects that were unavoidable with conventional inspection devices of this type, and to efficiently inspect photographic prints. The present invention will now be explained in detail with reference to the illustrated embodiments.

F/F-6, etc. are flip-flop circuits that prioritize reset, and T1, T2, T3, etc. are timers, and timer T1 is for stopping defective photographic prints at a position where punch holes can be made as markers. The stop position, that is, the time taken into account the running speed, can be adjusted, and OR is an OR circuit, AND
-1, AND-2, AND-3, AND-4, etc. are AND circuits, each member of which is connected as shown.

The photographic print inspection device according to the present invention is constructed as described above, so when it is used, a long photographic print P wound into a roll is mounted on the feeding shaft 2, and then The tip of the reader is attached to the winding shaft 3 through the top plate 5 of the inspection table 4, and the operation is started after preparing for inspection of each photographic print p ₁ , p ₂ , ... The operation involved is as shown in the flowchart shown in Figure 4.Press and hold the start switch button 7.
If the ON state is maintained, the winding shaft 3 is driven to guide the long photographic print P on the top plate 5 of the inspection table 4, and when the switch button 7 is released and the switch button 7 is turned OFF, The cut mark detector 14 detects the cut mark c made on the long photographic print P, and the drive of the winding shaft 3 is released to stop the photographic print P at a predetermined position, so that the photographic print is made over. If the switch button 8 is to be pressed, the makeover indicating hole 16 is activated, and when it is recognized that the object should be rejected, the switch button 9 is pressed, the redirect indicating hole 20 is activated.
A mark to that effect is placed on the photographic print, and then the winding shaft 3 winds up one photographic print and then stops. At this time, if you keep pressing the makeover switch button 8 or the reset switch button 9 to maintain the ON state,
Signs to that effect will continue to be posted one after another.

As is clear from the above description, when using the present invention, in which a punch hole is added to a defective photographic print as a sign to indicate the fact, it is not possible to use the conventional method of manually punching a defective photographic print using a graphite pen or the like. As in this type of photographic print inspection equipment,
Not only is there the uncertainty of this dirty photo print not being sorted by the auto selector and being mixed in with good quality, appropriate photo prints, causing discomfort or distrust to the customer, but also other good quality prints. It has now become possible to provide a photographic print inspection device that does not cause situations such as the transfer of graphite, which contaminates proper photographic prints and induces detection errors during sorting by the auto selector.
