After shooting, film with such an information recording section (hereinafter also referred to as EL film) is pulled out of the cartridge at a developing laboratory in the same way as regular 135 type film (hereinafter also referred to as 135 film), and is placed near the entrance/exit of the cartridge. cut and separated from the cartridge. After the EL film has been developed, the end portion of the EL film is latched onto the spool of the return cartridge, and the film is wound up and housed in the return cartridge for further processing. That is, when printing, a return cartridge containing film is set in a printing device equipped with an information reading section. This printing apparatus is equipped with a negative film carrier, and this negative film carrier has a transport roller that transports the film, a magnetic head that reads information on the EL film, and a perforation detection sensor that connects the support part of the cartridge and the exposure part. is provided in between. The film is pulled out from the return cartridge, the shooting conditions etc. recorded in the information recording section of the film are read, and the printing process is automatically performed.After the printing process is completed, the film is rewound into the return cartridge again. It will be done. The film after processing is returned to the customer in a return cartridge.

By the way, when processing both a conventional 135 film (a film that does not have an information recording section) and an EL film with one printing device, the transport roller, magnetic head and perforation detection sensor are In addition, a screen detection sensor for detecting the screen of 135 film is separately required.

However, if all of these sensors are placed between the exposure section and the cartridge support section, the distance from the cartridge support section to the exposure section becomes long, and the end of the negative is attached to the spool of the return cartridge. There is a risk that the final frame of the film will not reach the exposed area.

It has also been considered to solve the above drawback by attaching a spare film or the like to the spool of the return cartridge in advance, connecting a developed film to the spare film, and then storing the film in the return cartridge. However, the work becomes complicated and new spare film is required, leading to an increase in costs.

[0006]

SUMMARY OF THE INVENTION In consideration of the above-mentioned facts, the present invention is designed to be able to process both 135 film and film having a magnetic information recording section, but it is also possible to process the final frame of the film pulled out from the cartridge by the exposure section. The purpose is to obtain a negative film carrier that can be reliably placed in the film.

[Operation] According to the negative film carrier of the present invention, 13
The cartridge containing five films is set on the first support section. The 135 film pulled out from the cartridge is conveyed to the printing mask through the first conveyance path. Before the 135 film pulled out from the cartridge is conveyed to a printing mask, an image detection sensor detects the position of an image frame, and a perforation detection sensor detects perforations. The conveyance amount of the negative film is determined by the number of counts of perforations, and the image frame can be accurately conveyed to the print position on the negative film carrier. Therefore, by using the negative film carrier of the present invention in an automatic printing apparatus, the automatic printing apparatus can automatically print image frames of 135 films onto photographic paper.

Further, a cartridge containing a film having an information recording section is set on the second support section. The film pulled out from the cartridge can be transported to a printing mask through a second transport path. Information such as exposure conditions is read from the information recording layer by an information reading sensor before the film having the information recording portion that has been pulled out is conveyed to a printing mask.

Therefore, by using the negative film carrier of the present invention in an automatic printing device, the automatic printing device can automatically print image frames of an EL film onto photographic paper based on information such as exposure conditions. .

[0011] Furthermore, since only the sensors necessary for printing the images on each film are disposed on the first transport path and the second transport path, there is a gap between the first support portion and the printing mask. And the dimension between the second support part and the printing mask can be minimized. Therefore, it is possible to ensure that the image of the final frame of the film pulled out from the cartridge reaches the printing mask.
