PURPOSE:To assure the delivery of the front end of a film to guide rails by pressing one end of a moving film guide to the side part of the delivery port of a film cartridge, thereby eliminating the spacing between the cartridge and a holder. CONSTITUTION:The cartridge 5 for letting off is mounted to a cartridge holder part 2 for letting off and the front end of the film 9 housed in the cartridge 5 is crimped by delivery rollers 52. A plunger 82a is then projected to oscillate an arm member 81 and to advance one end 7a of the moving film guide 7 mounted to one end 81a of the member 81 into an aperture 20 until this part comes into contact with the side part of the delivery port 50 of the cartridge 5. The spacing between the cartridge 5 and the holder 2 is closed in this way. The rollers 52 are driven to deliver the film 9 from the delivery port 50 to the guide rails 41 simultaneously when this state is attained.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an image recording device that records image information by irradiating a laser onto a long film, for example.

[Prior Art] As shown in FIG. 6, for example, a conventional image recording device includes a main body (not shown), a film feeding section 102 for a roll-shaped film disposed inside the main body, and a film feeding section 102 for feeding out a roll-shaped film from the film feeding section 102. a film collection section 103 that collects the film 109, a film feeding section 102, and a film collection section 10;
3, a main drive device 116 disposed on the film running path and driving the film 109 at a constant speed, and a laser optical system. It consists of an image information recording section 117 that irradiates laser light in the width direction of the film 109 that is held and driven by a main drive device 116.

This image recording apparatus employs an autoloading mechanism that places the film 109 at a predetermined position so that image information can be recorded on the film 109. In this case, the feed reel 153 wound with film 1'09 is stored in the film feed cartridge 105, and this is attached to the film stripping section 102, and when the start switch is turned on, the feed reel 153 is opened from the feed port 150 of the cartridge 105. The film 109 is sent out. The fed film 109 travels along a predetermined film path system while being guided by the film guide means '104, and autoloading is completed when the leading end of the film 109 is held by a take-up reel 163 for collection.

[Problems to be Solved by the Invention] When performing autoloading as described above, it is necessary to run the film 109 so that the leading edge of the film 109 fed out from the force-loading reel 105 reliably reaches the take-up reel 163. be.

However, since the cartridge 105 is configured to be detachably attached to the film feeding section 102, a gap 110 is formed between the cartridge 105 and the film feeding section 102. This gap 110 is formed structurally due to the fact that the cartridge 105 is removable, and it is difficult to eliminate it completely. Further, since the film 109 sent out from the cartridge 105 is wound around the delivery reel 153, it tends to become curved and warped due to the curling tendency, and this tendency is particularly strong in the case of a thin film. Therefore, as shown in FIG. 7, the leading edge of the film 109 that has been sent out from the outlet 150 of the cartridge 105 may enter the gap 110, causing a film jam.

Therefore, the technical object of the present invention is to enable the film to be reliably fed from the cartridge to the film guide means when autoloading is performed in an image recording apparatus.

[Means for Solving the Problems] An image recording device of the present invention includes a main body having a holder section for storing a film cartridge and a film guiding means;
a film cartridge that is detachably attached to the holder and has a delivery port for the stored film; and a film cartridge that is movably provided between the delivery port and the film guide means to transport the film sent out from the delivery port; The apparatus includes a moving film guide that guides the moving film guide to the guiding means, and a moving means that moves the moving film guide so that one end of the moving film guide comes into contact with the side of the delivery port.

[Operation] Before starting autoloading, the image recording apparatus of the present invention moves the moving film guide using the moving means to bring one end of the moving film guide into contact with the side of the outlet of the film cartridge.

This eliminates the gap that had been formed between the film cartridge and the holder at the film cartridge's outlet. Since autoloading starts in this state, the film that is fed out of the film cartridge's outlet may be curved. Even in this state, the leading edge of the film is reliably guided to the film guiding means by the moving film guide.

Furthermore, slack detectors 18 and 19 are provided on the upstream and downstream sides of the main roller 16 to keep the tension of the film 9 constant as it is conveyed on the main roller 16 by creating slack in the film 9. It is being

The laser microfilmer 1 of this embodiment is constructed as described above.

In order to record image information using the laser microfilmer 1, preparations are made in advance by performing autoloading to place the film 9 in a predetermined position. First, if the feeding cartridge 5 is not attached to the feeding cartridge holder section 2, the feeding cartridge holder section 2 is pulled out by pressing the pull-out button 11, and the feeding cartridge 5 is mounted in a predetermined position. . At this time, the film 9 wound around the delivery reel 52 and stored in the delivery cartridge 5 is held at its leading end by the delivery roller 52 so as to be ready for delivery.

Next, by turning on the autoloading start switch, the keep solenoid 82 is turned on, the plunger 82a protrudes, and the arm member 81 is swung. As a result, as shown in FIG. 5, the movable film guide 7 on the one end 81a side of the arm member 81 moves.
One end 7a thereof enters the opening 20 and comes into contact with the side of the outlet 50 of the feeding cartridge 5. Due to this contact of the one end portion 7a of the moving film guide 7, the gap 10 formed between the feeding cartridge 5 and the feeding cartridge holder 2 outside the feeding port 50 disappears.

Then, at the same time as this state is reached, the feeding cartridge 5

The film 9 is sent out from the delivery port 50. The fed-out film 9 is usually curved and warped due to curling, with its leading end facing toward the movable film guide 7. Therefore, the leading edge of the film 9 is guided by the moving film guide 7 to the next guide rail 4.
It will definitely be sent to 1b. Note that the keep solenoid 82 is timed so that it will turn on again at this point.
As the plunger 82a retreats, the moving film guide 7 moves via the arm member 81, and the contact with the side of the outlet 50 is released.

Thereafter, the film 9 is guided by each of the guide rails 42 to 47 of the film guide means 4 and reaches the take-up reel 62 of the recovery cartridge 6, and its leading end is supported by the supporting mechanism. This completes autoloading,
Image information can be recorded on the film 9 by operating the main roller 14, the optical unit 15, etc.

As mentioned above, the laser microfilmer of this example is
Since one end 7a of the moving film guide 7 is brought into contact with the side of the outlet 50 of the feeding cartridge 5 during autoloading, the gap formed between the moving film guide 7 and the outlet 50 is reduced. 10 can be eliminated. Therefore, the leading end of the film 9 sent out from the delivery port 50 can be reliably guided to the guide rail 41b by the moving film guide 7.

[Effects of the Invention] The image recording device of the present invention includes a moving film guide that guides the film sent out from the outlet of the cartridge to a film guiding means, and one end of the moving film guide abutting the side of the outlet. It is equipped with a moving means for moving the vehicle. As a result, during automatic loading, one end of the moving film guide is brought into contact with the side of the outlet of the cartridge by the moving means, and the gap formed between the cartridge and the holder at the outlet is eliminated. Therefore, the film can be reliably fed from the cartridge to the seven-inch guide means.
