JPS58174931A - Blank feed mechanism of film - Google Patents

Abstract

PURPOSE:To improve working efficiency, by blank feeding the exposed and fogged part of a loaded film in accordance with an operation signal, cutting the film, and guiding the cut film so as to prohibit the passage thereof through a film storage part. CONSTITUTION:A guide selecting member 16 is normally in the position of a solid line, and is moved to the position of a broken line by the operation signal for blank feeding of film. The film fed to this mechanism in an arrow direction A from a camera section is conveyed directly to the processor section in an arrow direction D past a guide 13d. The set time for a timer for opening the guide 13d and blank feeding of the film is satisfactory if it is enough for delivering the exposed and fogged part of the film beyond a cutter 15. A feed roll operates only for this time to deliver the film to the guide 13d, whereafter the film is cut by the cutter 15. The cut film is fed to the processor section without the passage through the film storage track.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera processor capable of photographing a manuscript or the like on a microfilm and performing all photographic processing steps such as development, fixing, washing, and drying. In particular, the present invention relates to a film feed mechanism of this type of device.

This type of device is usually configured to open the opening/closing lid provided on the camera unit and load film wrapped in susol, etc. When loading film, it is done in a bright room, so the film cannot be easily loaded. The leading edge and the outer part of the film wound on the spool are subject to exposure fog. Furthermore, if the inner film wound around the spool is placed in a bright place, this exposure fog will gradually occur over time. For this reason, the longer the work time required to load the film, the more the number of light-filled dragons will increase. .

Since film is wasted in areas where such Km light fogging occurs, various methods have been developed to minimize such areas. For example, the film supply spool section is made into a separate box, so that the amount of film that can be pulled out from the spool is reduced. Alternatively, methods have been used to shorten the working time by reducing the number of film passing rollers in the camera section, or by configuring the film passing rollers to move so as to facilitate film loading. However, although the amount of overexposure can be reduced by the various methods described above, it cannot be completely eliminated. Because of this overexposure area, when taking a picture, you may not be able to start shooting right away, or you may have to avoid the overexposure area when taking pictures. Furthermore, when editing a film, the work efficiency is poor because overexposed areas must be cut out.

The present invention has been made in view of the above-mentioned points with the aim of improving work efficiency.

That is, the camera processor consists of a camera section that takes pictures, a film storage section that stores the film taken by the camera section, and a processor section that continues to process the film stored in the film storage section. The film feeding mechanism is such that the portion of the supplied film loaded into the camera section that has caused light fog is fed in response to a single actuation signal and cut, and the cut film is transferred to the film storage section. This film feeding mechanism is characterized in that it is configured to be guided without passing through the film. By doing this, the drawbacks of the conventional method can be overcome.

Hereinafter, the present invention will be explained using the accompanying drawings.

FIG. 1 shows a camera processor according to one practical example of the present invention. This device is roughly divided into a camera section 1, a film storage agent 2. Processor section 3. It consists of The film storage system of the film storage section 2 is based on the patent application filed in 1986-2, which was previously proposed by the present applicant.
This is a rumored system disclosed in No. 06090, and its configuration is shown in FIG.

To briefly explain this operation, two sets of film winding tracks consisting of a reel 18, a pair of rollers 20, 20a, and a film guide member 21, a reel 19, a pair of rollers 22a, 22, and a film guide member 26 move around the reel. As shown in the figure, the two sets of take-up tracks are arranged on the camera side and the processor side by rotating by 180 @ by the rotatable support shaft 25 which is perpendicular to the rotation axis 28. Further, the roller 25 transmits the driving force for winding the film, and the roller 24 transmits the driving force for feeding the film, so that the film can be photographed even during photographic processing.

When loading film into this camera processor, open the opening/closing lid provided on the camera section 1, place the film F wound on the spool 5 before shooting onto the holding rollers 7 and 8,
As shown in the figure, roll the film F onto the roller 9. The leading edge of the film F passes through the roller 12 and enters the entrance 1 of the film guide.
5a, turn the external knobs of the film feed rollers 14, 14a at the entrance of the film storage section 20, and hold the leading edge of the film with the feed rollers 14.1i1a. When turning the above-mentioned knob, a film tip stop knob 27 is provided between the cutter 15 and the guide 9 switching member 16 to prevent the tip of the film F from exceeding the guide switching member 16 due to excessive rotation. This is convenient without interfering with the operation of 16.

As described above, the feed rollers 14 and 14a move the film F.
The film loading operation is completed by holding the tip of the camera section 1, and the opening/closing lid of the camera section 1 is closed.

Until the aforementioned lid is closed, the exposure fog on the film F is gradually progressing. Detection/? -6 is ryIK
The moving roller 10 also moves from the position G at the time of film loading to the position H. The operation of the moving roller 10 facilitates the loading of the film F, and in this device, since the document 4 is photographed through the lens 11 at the roller 12, the film F is wound around the roller 12 at an angle. By making the image larger and bringing it closer together, it becomes easier and more stable to take pictures. By the movement of the moving roller 10 from the G position to the H position, a drive signal is input to the feed roller 14.degree. 14a, which feeds the film idly, and a mechanical timer that determines the drive time is set. This timer can also be set as an electric timer by actuating a microswitch using the moving roller 10 or the latch mechanism of the opening/closing lid.

FIG. 6 is a diagram showing the operation of the guide switching member 16 and the path of the film F. The guide switching member 16 is normally at the position shown by the solid line in the figure, and in response to the above-mentioned film feed operation signal #J, the guide switching member 16 is moved to the position shown by the broken line in the figure, and is in the input direction in the figure. Camera section 1
The film F sent from the film guide 91
5d and is directly transported to the processor section S in the D direction. Further, when the guide 9 switching member 16 is at the position indicated by the solid line described above, it guides the photographed film F from the input direction to the direction B, winds it up with the take-up reel, and cuts it with the cutter 15 when the desired position is reached. After winding the cut rear end to the outside of the film guide 15b, the film storage track rotates in the manner described above, and the wound film passes through the film guide 15c from direction C and D.
The photographic image is sent to the processor section 5 for photographic processing.

Simultaneously with the drive signal to the feed rollers 14, 14a described above and the setting of the timer, the guide switching member 16 operates to close the film guide 15b in the B direction as described above, and at the same time, the film leading edge stock e27 is also moved as shown in the figure. Move from the position indicated by the broken line to the position indicated by the solid line. This film 5t [stopper 27 is inserted into the guide switching member 1 when loading the film.
This is to ensure that the operation of 6 is not hindered.

In this way, the film guide 15d is opened, and the feed roller 14.14 is opened for the time set by the timer mentioned above.
a is activated to feed the film F. In this case, the set time for feeding the film F should be enough time to feed the overexposed part of the film beyond the cutter 15, and the set time is the working time required for loading the film,
This is determined by factors such as the speed of film feed. Normally, a safe value can be determined by calculating the time required for the film loading operation of this device, and the above-mentioned timer allows the set time to be freely selected. The feed roller 14,
14a operates and moves the film F through the film guide guy)"15
After the film F is sent out to d, it is cut by a cutter 15, and the cut film F is sent to the processor section 5 without passing through the film storage truck. When the rear end of the cut film F passes over the guide 3 switching member 16, the solenoid 9 connected to the guide switching member 16 is de-energized, and the guide switching member 16 switches to the film guide guide (1).
5d, after which photographing becomes possible.

Note that the film leading end stopper 27 stops when the remaining amount of film F becomes less than a preset amount as shooting progresses, and the cutter 1 stops.
5 is activated to close the film guide again after a predetermined time.

By configuring the structure as described above, when the film is overexposed due to loading a new film or opening the camera lid inadvertently, the film is skipped and the exposure is This allows the overlapped portion to be cut off and transported directly to the processor section without having to be wound up with a reel or the like. That is, it is possible to omit the process of winding up and temporarily storing the portion where exposure breakage occurred as described above, and furthermore, when simply using a blank feed, the speed is higher than that when winding for photographing. The film can be transported by Furthermore, in the case of idle feeding, both the camera feed speed and the processor feed speed may be switched to high speeds. Therefore, compared to conventional camera processors, the waiting time for starting photography after exposure overlap can be shortened, and work efficiency can be greatly improved.

In the above-described embodiment, the film guide is configured to transport even the film with overexposure to the processor section, but it can also be configured as shown in FIG. 4. In the figure, when the guide 9 switching member 16 is at the position indicated by the solid line, the film taken by the camera section is conveyed from the input direction to the B direction and temporarily stored on a reel, etc., and the wound film is then wound in the C direction. The signal is then sent to the D direction, which is the processor section. The film storage method in this case is similar to the above-mentioned example.

The cutter 15 and film tip stopper 27 also operate uniformly. However, when the guide switching member 16 is moved to the position indicated by the broken line in the figure in response to the same activation signal as in the actual example described above, the film that has been overexposed in the camera section is fed from the input direction to the E direction. This film guiding guide in the E direction is configured to guide the film out of the camera processor, and removes the film with overexposure from the cutter 1.
It is cut at 5 and discharged outside the machine. Further, a discharge roller or the like may be provided at the exit E.

This case of real power also has the same effect as the above-mentioned real power case.

In the two actual examples mentioned above, a film feed signal was issued in conjunction with the opening/closing operation of the camera unit, but it is not limited to this type of method. It has the same effect as.
