Abstract

PURPOSE:To discharge a selected photograph with its front and rear sides being inverted, other than the other photographs, by providing an inverting guide plate for holding a photograph discharged from a discharge roller in a curved condition. CONSTITUTION:In such a condition that the trailing end R of a photograph P which has been developed and cut, it still driven to be discharged by a discharge roller 8, an inverting guide plate 12 holds the leading end T of the photograph P in such a condition that it is inverted upward and curved to be convex upward. Thereafter, when the trailing end R of the photograph P is ejected from the discharge roller 8, the photograph P is released in such a condition that the trailing end R of the photograph P is in the forehead, that is, the photograph P is inverted. Further a change-over section may be switched between an operating position where the discharged photograph abuts thereto, and an inoperative position which is shifted from the operating position. Thereby, when it is at the inoperative position, the photograph is discharged with its front surface facing upward.

Description

[Detailed description of the invention] C Industrial application field] The present invention relates to an automatic photographic processor.

[Prior art]

In an automatic processor that develops printed photographic paper to form photographs, a continuous long sheet of photographic paper that is dried and discharged after development is cut into pieces according to information specified for each photographic image. The photos become so-called photographs, which are discharged from a photograph outlet and deposited in a box-shaped discharge container with an open top.

In such an automatic processor, it is necessary to divide the large number of photographs formed into groups, for example, into groups of photographs of one order corresponding to one photographic film. For this purpose, a suitable sorting mark is formed on the photographic paper at the beginning position of a group of photographs forming the I group, and the sorting mark is detected in the photographic discharge section, and the photographic group is deposited in the discharge container in accordance with the sorting mark. A device has been developed in which a partition chip is automatically interposed between the two.

[Problem that the invention seeks to solve]

However, in such conventional devices, the structure of the photo ejecting section of the automatic processor is extremely complicated.
The disadvantage is that a partition chip is required and the overall cost is high.

Therefore, if the first photo of each order can be discharged upside down, sufficient partitioning will be achieved, and since no partitioning chip is required, the same effect can be obtained very easily. This is very advantageous.

The present invention has been completed from the above points of view,
The purpose is to provide an automatic developing machine that can eject a selected photograph with its front and back reversed from other photographs with a simple configuration.

[Means for solving problems]

In the present invention, there is provided a discharge roller that discharges a photograph cut from developed photographic paper diagonally upward forward from a photograph discharge port, an operating position in front of the discharge roller where the photograph to be discharged comes into contact with the A switching member is provided to be able to switch between an operating position and a non-operating position, and the switching member has a shape that continues above the switching member in the operating position and is curved so as to be reversed. A reversing guide plate is provided to hold the photograph in a curved state, thereby constituting an automatic developing machine.

[Effect]

In such an automatic developing machine, while the trailing edge of the developed and cut photo is still being discharged by the ejection roller, the leading edge of the photo is flipped upward by the reversing guide and convex outward. Then, when the rear end of the photograph is released from the ejection roller, the repulsive restoring force of the photograph causes the rear end of the photograph to be at the top, that is, the photograph is turned upside down, and the photograph exits the ejection port. will be released more.

〔Example〕

FIG. 1 shows an embodiment of the present invention, in which 1 is an outer box of the photo output section of an automatic processor, 2 is a photo outlet of the outer box 1, and the photos are developed on a continuous long photographic paper. is discharged upward from the dryer 3 via rollers 4. 5 is an accumulator section, 6 is an accumulator sensor, 7 is a drive roller,
8 is a discharge roller, 9 is a Hall sensor, and 10 is a cutter. The U-feed roller 8 is driven by a pulse motor (not shown) together with a drive roller 7, and conveys the photographic paper or photograph diagonally upward. In front of the discharge roller 8, the upper end of the switching member 11 is pivotally supported so that it can rotate, and a rotary solenoid (not shown) causes the leading edge of the photograph to be discharged, indicated by a solid line, to collide. It is possible to switch between an operating position and a non-operating position, which is shown by a chain line, and a non-operating position where the leading edges of the photographs that are opened upward from the operating position and are ejected do not collide. Ejection roller 8
A reversing guide plate 12 is provided above, and this reversing guide plate 12 is curved so as to be reversed upward from the lower end edge located next to the upper edge of the switching member 11, and furthermore, the reversing guide plate 12 It has a shape that extends in a substantially horizontal direction in the opposite direction to the passage. A guide member 13 is provided below the switching member 11 in front of the discharge roller 8 and is inclined downward. Reference numerals 14 and 15 are loading guides, and an upper guide 15 is provided so as to be rotatable upward. 16 is a discharge container provided below the front of the guide member 13, 17 is a chip storage container provided below the cutter 10, 18 is a guide roller provided in the discharge container 16, and S is a photo stack inside the discharge container 16. It is.

The device having such a configuration operates as follows.

First, the photographic paper fed out from the dryer a3 via the roller 4 is loaded. The leading end of the photographic paper on the roller 4 is guided to the drive roller rough by the loading guide I4□15' and further reaches the discharge roller 8. Then, the pulse motor that is the drive source for the drive roller 7 and discharge roller 8 is stopped by a signal from the Hall sensor 7, but the discharge of photographic paper from the dryer 3 continues, and as a result,
The photographic paper is placed in the rotatable upper guide 1 as shown by the two-dot chain line.
5 is pushed upward and curved, forming an accumulator section 5. This formation of the accumulator portion 5 continues until the photographic paper comes into contact with the accumulator sensor 6. Loading of photographic paper is thus completed.

In this state, the photographic paper discharged from the dryer 3 is cut into individual photographs and discharged. That is, when a continuous long piece of photographic paper passes through the hall sensor 9 following the drive roller 7, the holes formed in the photographic paper are optically detected by the hall sensor 9. This hole, depending on its position and/or number, has sort marks and/or
or may function as a cut mark, or may further function as a cut mark indicating the type of photograph (for example, "with border" or "without border").

The pulse motor is controlled according to the information contained in the hole detected by the hole sensor 9, which drives the drive roller 7 and discharge roller 8 to feed the photographic paper at a controlled length, and the cutter 10 is energized and the photographic paper is cut along one or two cutting lines. If chips come out from this cutting, use the chip container 1.
Fall within 7.

When the detected hole is not a sort mark, the switching member 11 is fixed in its operating position by the rotary solenoid, and as a result, as shown in FIG. roller 8
When the paper is ejected from the paper, its leading end T comes into contact with the switching member 11, and then, since the path by the ejecting roller 8 and the like is directed diagonally upward, the leading end T begins to advance upward. Further, as the ejection operation of the ejection roller 8 continues, the photograph P is guided along the temporary reversing guide 12, and as a result, as shown in FIG. While being suppressed, the rear end R is still held between the discharge rollers 8 and held in an outwardly curved state as a whole. When the rear end R of the photograph P is released from the discharge roller 8, the repulsive restoring force caused by the forcible bending of the photograph P causes the rear end R of the photograph P to appear as shown in FIG. The rear end R is the first and the discharge roller 8
When the image surface (emulsion surface) is facing downward at the cutting position, the image is The paper enters the discharge container 16 with the surface facing upward and is deposited.

Even if the rear end of the photograph P is separated from the discharge roller 8, but the rear end is caught on the guide member 13 or the like and does not jump into the discharge container 16, the subsequent photograph is kicked forward, and is finally discharged into the discharge container 16 in the expected state.

On the other hand, when the detected hole is a sorting mark, the switching member 11 is opened and switched to its inactive position, so that the cut and formed photograph has its leading edge obstructed by the switching member 11. It is guided into the discharge container 16 by the guide member 13 without moving. Therefore, if the image plane is facing downward at the cutting position,
The images are deposited by entering the discharge container 16 with the image surface facing downward. [Effects of the Invention] As described above, according to the present invention, when a sort mark is detected, compared to when it is not detected, 17) By simply switching the position of the switching member 11, it is possible to reverse the front and back sides of the photograph to be taken out, and in particular, the apparatus does not include a mechanism that moves in contact with the photograph in order to reverse the photograph, and therefore has a complicated structure. As a result, with an extremely simple configuration, it is possible to eject, for example, the first photo of each order in an upside-down state. Sufficient partitioning is achieved and no extra materials such as partitioning chips are required.

In addition, in the automatic processor according to the present invention, it is completely free to decide what kind of photograph groups to partition, what kind of signals to switch to inversion, and which photographs to invert.
