Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a camera processor capable of photographing a document 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 feeding device of this type of device.

This type of device is normally configured to open an opening/closing lid provided on the camera unit and load film wound on a spool, etc. When loading film, it is done in a bright room, so it is difficult to load the film. The leading end and the outer periphery of the film wound around the spool are subject to exposure overlap. This exposure fog also occurs gradually over time when the inner film wound around the spool is placed in a bright place. Therefore, the amount of overexposure increases the longer the working time required to load the film.

Since the film is wasted in such areas where overexposure occurs, various methods have been used to reduce such areas as much as possible. for example,
A method in which the film supply spool section is placed in a separate box, reducing the amount of film that needs to be pulled out from the spool. 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, overexposed areas are cut out, resulting in poor work efficiency.

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

That is, an object of the present invention is to provide a camera section for taking pictures, a film storage section for temporarily storing the film taken by the camera section, and a processor section for continuing photographic processing of the film stored in the film storage section. A film feeding device for a camera processor comprising: a cutter for cutting the film fed from the camera section; and a cutter for cutting the film fed from the camera section, and a cutter for cutting the film fed from the camera section, and a cutter for cutting the film fed from the camera section, and a cutter for cutting the film fed from the camera section, and a cutter for cutting the film fed from the camera section, and a cutter for cutting the film fed from the camera section. A film guide for feeding the film and a film guide for not feeding the film into the film storage section are provided separately,
A guide switching member for opening and closing each of the film guides is provided at the branching point, and in response to an actuation signal to feed an unnecessary part of the film, the guide switching member is switched to close the film storage section, and also switch the film storage section to close the film storage section. This can be achieved by a film feeding device characterized in that the film is cut by the cutter.

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

FIG. 1 shows a camera processor according to an embodiment of the present invention. The apparatus is broadly divided into a camera section 1, a film storage section 2, and a processor section 3. The film storage system of the film storage section 2 is the system disclosed in Japanese Patent Application No. 56-206090, which was previously proposed by the present applicant, and its construction is shown in FIG. To briefly explain this operation, the pair of rollers 20, 20a of the reel 18, the film guide member 21, the reel 1
Two sets of film winding tracks consisting of a roller 9, a pair of rollers 22a, 22, and a film guide member 26 are provided on the rotation shaft 28 of the reel as shown in the figure.
A rotatable support shaft 25 perpendicular to its rotation axis 28
By rotating 180 degrees by the rollers, the two sets of winding tracks mentioned above alternately correspond to the camera section side and the processor section side, and the driving force for winding by the roller 23 is transferred to the winding drive force by the roller 24. It is configured so that the driving force for advancing the film is transmitted and photography can be taken even during photographic processing.

When loading a film into this camera processor, open the opening/closing lid provided on the camera unit 1, place the film F wound around the spool 5 on the holding rollers 7 and 8, and place the film F on the holding rollers 7 and 8 as shown in the figure. pass through rollers 9 and 12, and insert the leading edge of the film F into the entrance 13a of the film guide.
Film feed roller 1 at the entrance of film storage section 2
Turn the external knobs 4 and 14a to release the feed roller 1.
4. Hold the leading edge of the film with 14a. When turning the aforementioned knob, a film tip stopper 27 is provided between the cutter 15 and the guide switching member 16 to prevent the tip of the film F from exceeding the guide switching member 16 due to excessive rotation. Convenient without interfering with operation.

As described above, the film loading operation is completed with the feed rollers 14, 14a holding the leading edge of the film F, 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. In conjunction with this operation of closing the opening/closing lid, the detection lever 6 for detecting the remaining amount of film moves to the position shown by the broken line in the figure, and the moving roller 10 also moves from position G to position H when loading the film. 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 wrapping angle of the film F around the roller 12 is increased. To make photography easier and more stable by bringing it into close contact. A feed roller 1 that feeds the film by the movement of the moving roller 10 from the G position to the H position.
A drive signal is inputted to 4 and 14a, 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. 3 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, the guide switching member 16 is moved by a solenoid or the like to the position shown by the broken line in the figure, and is moved in the direction A in the figure. A film F sent from a certain camera unit 1 is passed through a film guide 13d D
It is configured to be directly transported to the processor section 3 in the direction. Further, when the guide switching member 16 is at the position indicated by the solid line mentioned above, it guides the photographed film F from the direction A to the direction B, winds it up with the take-up reel, and cuts it with the cutter 15 when the desired amount is reached. After the cut rear end is rolled up to the outside of the film guide 13b, the film storage track is rotated in the manner described above, and the wound film passes through the film guide 13c from the C direction to the processor section 3 in the D direction.
The photo is then sent to the camera for photo processing.

The guide switching member 16 simultaneously sends the drive signal to the feed rollers 14, 14a mentioned above and sets the timer.
operates to close the film guide 13b in the B direction as described above, and at the same time the film leading end stopper 27 also moves from the position shown by the broken line to the position shown by the solid line. This film leading end stopper 27 is provided to ensure that the operation of the guide switching member 16 is not hindered when loading a film.

In this way, the film guide 13d is opened, and the feed roller 1 is opened for the time set by the timer mentioned above.
4 and 14a operate to feed the film F.
In this case, the set time for feeding the film F should be sufficient 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, and the time required to feed the film at no time. This is determined by factors such as speed. It is possible to determine a safe value by calculating the time normally required for film loading in this device.
The above-mentioned timer allows the set time to be freely selected. After the feed rollers 14, 14a operate for the time set by the timer and feed the film F to the film guide 13d, the cutter 1
5, and the cut film F is transferred to the processor section 3 without passing through the film storage track.
sent to. When the rear end of the cut film F passes over the guide switching member 16, the solenoid connected to the guide switching member 16 is de-energized, and the guide switching member 16 switches the film guide 1.
3d, and after that it is possible to take pictures.

The film leading end stopper 27 is configured so that as photography progresses and the remaining amount of film F becomes less than a predetermined amount, the cutter 15 is operated to close the film guide again after a predetermined period of time.

With the above-described configuration, when the film is exposed due to overexposure, such as when newly loaded film or when the camera lid is carelessly opened, the film can be skipped and the exposure overlap can be avoided. This makes it possible to cut off the part where the paper has broken and transport it directly to the processor section without having to wind it up with a reel or the like. In other words, it is possible to omit the process of winding up and temporarily storing the overexposed part mentioned above, and furthermore, the speed of winding up for photographing is faster than that of winding up for photographing. It is capable of transporting film. 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 improved.

In the above-described embodiment, the film guide is constructed so that the film with overexposure is also transported to the processor section, but the film guide may be constructed as shown in FIG. 4. In the figure, when the guide switching member 16 is in the position indicated by the solid line, the film taken by the camera section is conveyed from direction A to direction B and temporarily stored on a reel or the like, and the film wound up after that is transported from direction A to direction B. The signal is sent from the direction to the D direction, which is the processor section. The film storage method in this case is the same as in the previous embodiment, and the cutter 15 and film tip stopper 27 operate in the same manner. 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 previous embodiment, the film that has been overexposed in the camera section is sent from the direction A to the direction E. This film guide in the E direction is configured to guide the film out of the camera processor.
The film with overexposure is cut with a cutter 15 and discharged outside the machine. Further, a discharge roller or the like may be provided at the exit E. This embodiment also has the same effects as the previous embodiment.

In the two embodiments described above, the film blank feed signal is issued in conjunction with the closing operation of the opening/closing lid of the camera unit. This has the same effect as the example.
