Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides an image processing system in which a microfilm sent out from a film storage section is wound onto a film reel in a winding cartridge through a film running path including an image exposure section. It relates to a recording device.

In recent years, various devices have been provided that record an image on a long microfilm using a laser beam for one frame. This type of device generally consists of a raw film cartridge for supplying unexposed raw film, a laser beam optical system, a take-up cartridge for sequentially winding recorded film, and an optical system for exposing the raw film. It is comprised of a film transport mechanism that transports the film to a position and further transports it to a winding cartridge, and a control mechanism.

By the way, in the past, loading the film into the device was done manually, which was extremely complicated.

That is, when starting to wind the film around the core of the take-up film reel attached to the cartridge, insert the leading edge of the film into the notch provided in the core, and while holding it with your fingers so that the leading edge of the film does not fall out of the notch. The leading edge of the film is fixed to the core by winding the film around the core several times, and then the film is automatically wound onto the film reel by a drive unit.

Therefore, as disclosed in Japanese Unexamined Patent Publication No. 63-267937, the present applicant has developed a holding mechanism that uses a special film reel to hold the leading edge of the film being fed, and a mechanism that drives the held film by this holding mechanism. We have proposed an automatic film winding device consisting of a winding section that is driven by a winding section. However, since this film winding device uses a dedicated film reel having a clamping mechanism, there is a problem in that commercially available film reels cannot be used and the cost is high.

The present invention has been made in view of the above-mentioned problems, and its object is to be able to use a commercially available film reel as it is to automatically start loading the film, in particular automatically winding the leading edge of the film onto the film reel. Moreover, it is an object of the present invention to provide an image recording device in which the film can be reliably wound around the film reel.

In order to solve the above problem, the image recording device according to the present invention elastically presses the film fed into the winding cartridge against the core of a rotationally driven film reel. A film guide means for guiding the winding of the film is provided, and at the end of automatic loading of the film, the film reel for winding is driven to rotate for a certain period of time after feeding of the film to the winding cartridge is stopped.

A normal film reel without any special processing is used as the winding film reel, and the film is guided while being pressed by a guide means, and is wound onto the outer periphery of the core. The leading edge of the film is in sliding contact with the outer circumferential surface of the core, and after the feeding of the film into the winding cartridge has stopped, the film reel for winding is driven to rotate for a certain period of time, so that the leading edge of the film is in contact with the outer peripheral surface of the core. It will definitely get caught up in the core.

Embodiments Hereinafter, embodiments of a laser beam image recording apparatus for microfilm according to the present invention will be described with reference to the accompanying drawings.

Here, the running of the film will be explained.

Film is automatically loaded (autoloading). First, the film sent out from the delivery rollers (80) and (81) is conveyed to the slack detector (161) via the guide member (160), and furthermore, the film is sent to the slack detector (161) via the guide member (160), and then the film is sent to the slack detector (161) via the guide member (160).

It is brought into close contact with the main roller (170), and is conveyed to the slack detector (181) via the guide member (179) by rotation of the main roller (170). moreover,
A conveying force is applied by slack control rollers (183) and (184), and the film is wound onto a film reel (145) in a winding cartridge (100).

Slack control by the slack detector (181) and completion of autoloading are performed based on the timing chart shown in FIG. That is, when the leading edge of the film is conveyed from the main roller (170) to the slack detector (181) during autoloading, the leading edge of the film is first detected by the photosensor (SE6), and then further detected by the photosensor <5E5). be done.

When the photosensor (SE5) detects the leading edge of the film, the feed motor (Ml) is activated. As a result, the drive roller (183) is rotationally driven, and the roller (183) <

When autoloading starts and the photo sensor (SE5) turns off for the first time, the take-up cartridge (100)
The shutter (104) (see FIG. 3, described below) is opened when the lens is turned on. The leading edge of the film goes from the slit (103) to the winding cartridge (100).
The winding remoter (M3) moves the arrow (a)
) direction, the 0-winding remoter (M3) winds up the film reel (145) that is rotationally driven in the direction of the feed motor (
The film reel (145) is controlled to turn on and off at the same timing as Ml>, and the leading edge of the film is moved to an appropriate length.
When the feed motor (212) is wound onto the core (146), that is, when the slack control period (ta) ends, the rotation of the feed motor (212) is stopped.

In addition, the sag control for the delivery motor (Ml) by another sag detector (161) is also performed by the sag detector (161).
This is similar to the slack control by 181). That is, the film is conveyed in an arc even within the sag detector (<161), and when the bulge of the film is detected (turned on) by the boot sensor (SE3), the rotation of the feed motor (Ml) is stopped and the film is [During this time, the film is transported by rollers (163) and (164).When the photo sensor (5E4) detects that the film is no longer bulged (turned off), the feed motor (Ml) restart the rotation.

By the way, in normal autoloading, the feed motor (M2) eventually stops working after the slack control period (Ta) has elapsed.

) and the film winding speed [circumferential speed of core (146)] are not so different, as shown in Figure 5a, the film (F) will not be tightly wound around the core (146) and will sag. Therefore, in this embodiment, at the end of autoloading, the feed motor (M2) is turned on to stop the rotation of the rollers (183) and (184), and then the take-up motor (M3') is turned on. rotation for a certain period of time (tb
) will be extended.

As a result, the leading end of the film (F) is wound around the core (146), and as shown in FIG. 5b, the film (F) is tightly wound up in a good condition.

On the other hand, image recording by the optical unit (200) uses the laser beam scanning (scanning perpendicular to the top of the paper in FIG. 2) by the aforementioned polygon mirror as the main scanning, and the film is transported by the rotation of the main roller (170). is performed as a sub-scan. At this time, the main roller (170) is rotated at a constant speed, the feed roller (80> is subjected to slack control by a slack detector (161), and the feed roller (183) is controlled by a slack detector (181). Control takes place.

When the desired recording is completed, the cutter (169) is operated to cut the film and wind the cut film onto the film reel (145).

(142), the guide portion (140a) is ready to guide the film wound around the core (146).

Here, the operation of attaching and detaching the film reel (145) will be explained together with the operation of each film guide means (110) and (135).

When attaching the film reel (145) to the cartridge (100), first open the cover (not shown) and insert the second
The film guide means (135) of the arm (136) is rotated upward, and the notch (136e) is inserted into the stopper bin (
144), the arm (136) and the guide plate (
140) is the flange (14) of the film reel (145).

00). At the same time, the film reel (145
) is also rotationally driven in the direction of arrow (a). Slit (10
3) The leading edge of the film passes through the film support (
120) and guided between the guide roller (138) and the core (146);
The core (146) is rotated by the film reel (145).
Propulsion is given by. The leading edge of the film is guided by the guide portion (140a) of the guide plate (140) by this driving force, and is guided by the arrow (a) so as to wrap around the core (146).
direction, guide roller (142), (116g)
is guided by the guide portion (115a) of the guide plate (115), and the guide roller (116b) and core (146)
be guided between. The leading edge of the film enters between the core (146) and the succeeding film being pressed by the guide roller (13B) at the position where it has made one rotation, and the succeeding film is wound onto it.

The guide plates (115) and (140) both have cores <146
) so that it can swing elastically toward
As the amount of film to be wound increases, the guide rollers (116b) and (138) rotate while in contact with the film and retreat outward. Note that when the amount of film to be wound increases, the other guide roller (116a), (1
42) comes into contact with the film and begins to rotate. After that, as the amount of film to be wound increases, the film guide means (1
10) approaches the side frame (102) while moving away from the core (146). Then gradually the guide roller (1
16a), the reaction force of the torsion coil spring (113) is applied, and the guide plate (115) rotates clockwise with respect to the arm (111) about the bottle (117a) as a fulcrum.

Therefore, the back (115b) of the guide plate (115) separates from the projection (lllc) of the arm (111), and the restriction on the film support (120) is released. The film support (120) holds the bottle (1
It rotates counterclockwise using 17b) as a fulcrum and begins to fold. In this way, the film support (120) folds up as it moves outwardly, and the lever portion (120a) rises to a horizontal position as it approaches the core (146). Therefore, the cartridge (100) can be made compact and economical since no special driving means is required just for folding the film support (120). On the other hand, since all rollers contact the film during winding, the film is not damaged.

When the film is automatically loaded and recording of a predetermined image is completed, the cutter (169) is operated as described above to cut the film and wind it onto the film reel (145). Thereafter, the cartridge (100) is removed from the recording apparatus main body, the cover (not shown) is opened, and the first and second film guide means (110) are removed.

(135) is retracted outward as described above, and the film reel (145) is removed from the cartridge (100).

As described above, the film of the cartridge (100) does not come apart even when the cover is opened, and the film reel (
145) can be taken out very easily. Also,
The film reel (145) itself does not require any special mechanism; a commercially available product can be used as is, and automatic loading of the film is also possible.

Note that the image recording apparatus according to the present invention is not limited to the above-described embodiments, and can be variously modified within the scope of the gist.

For example, the structure of the film bus unit (150) and the film guide means (100) in the cartridge (100)
10) and (135) can have various configurations.

As is clear from the above description, according to the present invention, the film fed into the winding cartridge is elastically pressed against the core of the film reel that is rotationally driven, and the film is wound. Since the film guide means is provided, not only is it possible to autoload using a commercially available film reel, but it is also possible to use a film reel for winding after the feeding of the film to the winding cartridge is stopped at the end of autoloading. Since the film reel is driven to rotate for a certain period of time, the film can be reliably and well wound onto the winding film reel without slack.
