Abstract

PURPOSE:To attain a roll film as intact as before it is used by providing a controller which interlocks a sensor counting a winding amount with a rewinding mechanism and stops said mechanism, with a roll film end part projecting from a cartridge by a prescribed amount. CONSTITUTION:The title device is provided with the sensor 22 detecting a winding amount with the aid of the number of perforations disposed in the rotating locus of the gear 12a of a gear 12 meshed with the perforations, and an electromagnetic clutch 15 and an LED flash lamp are controlled by the signal current of the sensor 22. The winding and rewinding amounts of the roll film 21 detected by the sensor 22 are counted, and signals indicating those amounts are transmitted to the controller 24. Then a rewining motor 14 is stopped with the end of the roll film 21 projecting from the cartridge 8 by a prescribed amount. Thus, after information is printed onto the roll film 21, it looks intact.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to an apparatus for printing various information such as the photographer's name on the perforation side corresponding to each frame of a roll film.

(Prior art) Conventionally, when manufacturing roll film, numbers and symbols for each frame were printed on the side of the perforations, or when the roll film was loaded into a camera and the date was imprinted on each frame when shooting. However, the photographer's name and other information for each frame of the roll film were not freely printed on the side of the perforation corresponding to each frame before the roll film was developed.

(Problem to be Solved by the Invention) By the way, in order to print the photographer's name and other information on the side of the perforations corresponding to each frame of the roll film before development, the roll film must first be taken out and then returned to its original state. It is conceivable to carry out the above-mentioned baking when winding the film, but in this case, the roll film is completely wound into the cartridge at the end, and the tip of the roll film is pulled out a certain length from the cartridge and the state is returned to the normal state before use of the roll film. There was a problem that it was difficult to make them the same.

(Means for Solving the Problems) The present invention has an object of solving the above-mentioned problems, and is aimed at rewinding a roll film in a light-shielded state, and attaching a sheet attachment section with an unwinding mechanism and information to the roll film when unwinding. It has an optical system that sequentially exposes the side of the perforation.
The present invention is characterized by a control device that interlocks the rewinding mechanism with a sensor that determines the amount of rewinding, and stops the rewinding mechanism when the end of the roll film protrudes a predetermined amount from the cartridge.

Hereinafter, a detailed explanation will be given based on the illustrated embodiment. 1 is a box-shaped housing with a roll film loading section lid 2 and a sheet loading section lid 3 with the photographer's name and other information written on its two sides, and a winding switch 4, a rewinding switch 5, and a winding switch 5 on the front. There is a power lamp 6 and a power switch 7. When the lid 2 is opened, there is a loading section 9 for the roll film cartridge 8 inside.
, a winding shaft 10, and an unwinding shaft 11. 12 is a gear that engages and rotates with the perforation, 13 is an unwinding motor connected to the unwinding shaft 1, 14 is a winding motor, and 15 is an electromagnetic clutch that connects the winding motor 14 and the winding shaft 10.

A is a lens on which the information of the information sheet 17 is printed, and 22 is a gear that meshes with the perforation 21b.]-2 is a sensor that detects the number of perforations arranged in the rotation locus of the tooth 12a, and this signal current The electromagnetic clutch 15 and the LED light emitting lamp 16 are controlled by this. 24 is the perforation 2], and the number detection sensor 22 detects the amount of winding and rewinding of the roll film 21. When the roll film 21 is rewound, one end of the roll film 2] is This is a control device that stops the retraction motor 14 when it protrudes from the I.Rone 8 by a predetermined amount.

Next, the effect will be explained. The lid 2 is opened, and the roll films 1 to 8 before photographing are placed in the loading section 9, and the shaft holes of the roll films 1 to 8 are rolled up and connected to the shaft 1°. The tip of the roll film 21 is placed over the unwinding shaft 11, the perforation 21b is engaged with the gear 12, and M2 is closed.

Next, the lid 3 is opened, a sheet 17 on which the photographer's name is written is placed on the seat 1 to the mounting section, and the lid 3 is closed.

Next, the power lamp 6 and the power switch 7 are turned on, and the unwinding switch 4 is turned on, and the unwinding motor 13 is activated to wind the roll film 21 onto the unwinding shaft 11.

When the roll film 21 is completely unwound, tension is applied to the roll film 21 and the operation of the unwind motor 13 is automatically stopped. Next, when the retraction switch 5 is turned on, the retraction motor 14 is turned on.
is activated, and the roll film 21 is rewound into the Pa1 Herone 8. At this time, the sensor 22 detects the rotation amount of the gear 12 meshing with the perforations 2 and b of the roll film 21, and counts 4 perforations 21b, which are one frame of the roll film 21. Then, this detection signal=4- actuates a control device (not shown) to disconnect the electromagnetic clutch 15 and stop the movement of the roll film 21. At this time, the control device simultaneously causes the LED light emitting lamp 16 to emit light,
Using the optical system shown in FIG. 2, the photographer's name 23 written on the sheet 17 is printed on the perforation 21b corresponding to the frame 21c of the roll film 21. In this way, the photographer's name 23 is sequentially printed on the perforation 21b corresponding to each frame. Figure S shows the rewinding motor 4, perforation 21b, and electromagnetic clutch.]
-5. 3 is a diagram showing the timing of an LED light emitting lamp 16. FIG.

In this way, all the pieces are burned. During this time, the number detection sensor 22 of the perforations 21b counts the amount of unwinding and winding of the film 21, sends this signal to the control device 24, and winds the roll film 21 with the end protruding from the cartridge 8 by a predetermined amount. Stop the return motor 14.

Note that instead of detecting and controlling the number of perforations, an end mark may be displayed at the end of the roll film, detected by a sensor, and the rewind motor 14 may be stopped in the above state.

Also, as shown in Fig. 7, the information sheets 1 to 30 are wound around a drum 31 and rotated, and the roll film 32 is continuously moved, and both are synchronized to print on the perforation side of each frame by slit exposure. In addition to the name of the photographer, the location where the photograph was taken and various information associated with the photograph may also be printed.

(Effects) According to the present invention, a roll film is wound in a light-shielded state, and
It has an optical system that sequentially exposes the perforation side of the roll film when rewinding the rewinding mechanism and the sheet mounting section with information written on it.The rewinding mechanism is linked with a sensor that counts the amount of winding, It is equipped with a control device that stops the rewinding mechanism when the end protrudes a predetermined amount from the cartridge, so even if the image of each frame of the roll film is copied, the image will not be the original image but a copy image. If you look at the original roll film of this image, you can confirm the name of the photographer, and you can definitely prevent copyright infringement of the roll film image.

In addition, as with normal roll film before use, printing can be completed with the end of the roll film protruding from the cartridge by a predetermined amount, and the roll film can be attached to the camera as is during use.
