Description

Detailed Description of the Invention "Industrial Application Field" The present invention relates to an image forming apparatus such as a copying machine, and particularly relates to an image forming apparatus that exposes a long photosensitive recording medium to form a latent image. The present invention relates to an image forming apparatus that performs development to obtain an output image.

"Prior Art" In general, photosensitive recording media used in this type of image forming apparatus have different photosensitive characteristics, developing characteristics, etc., depending on the manufacturing process, raw materials, types, etc.

For this reason, in conventional image forming apparatuses, the user inputs characteristic information of the photosensitive recording medium specified by the manufacturer into the apparatus using key operations, etc., and the image forming apparatus performs exposure, development, etc. based on the input information. Formation conditions were now set.

However, in this image forming apparatus, each time the user loads a photosensitive recording medium into the apparatus, the user must input characteristic information of the photosensitive recording medium by key operation, etc., and this operation is extremely complicated and time-consuming. In addition, it was easy to make mistakes in inputting characteristic information, and it often occurred that optimal image forming conditions could not be set.

In order to eliminate this problem, a bar code or other display section is attached to the leader tape provided at the starting end of the photosensitive recording medium to show characteristic information of the photosensitive recording medium, and this display section is attached to the leader tape provided at the starting end of the photosensitive recording medium. Image forming apparatuses have conventionally been proposed in which image forming conditions are set in accordance with the read information by a reading unit such as an optical reading sensor provided on the side of the image forming apparatus.

A display section such as a bar code is attached to the outer circumferential surface of the take-up roller for winding up the photosensitive recording medium after use, and this display section is provided on the device side. An image forming apparatus f has also been proposed in the past, which is configured to read information using a reading section such as an optical reading sensor, and set image forming conditions in accordance with the read information.

[Problem to be solved by the invention] However, in the conventional image forming apparatus described above, in a structure in which a display section such as a bar code is attached on a leader tape, a photosensitive recording medium is connected to a predetermined position via a leader tape. When the leader tape is passed through the conveyance path, it is easy for the leader tape to fluttering, and since the display section on the leader tape passes through the corresponding position with the reading section only once, it is difficult to read the characteristic information incorrectly. The problem was that it was easy to occur.

On the other hand, in the conventional structure in which a display section is attached to the outer peripheral surface of the take-up roller, when the photosensitive recording medium is passed through the leader chi 1 to a predetermined conveyance path, the rotation of the take-up roller Since reading is performed with the display unit facing the reading unit multiple times, reading errors do not occur.

However, in this conventional configuration, the take-up roller is attached to a storage container for the photosensitive recording medium, and the photosensitive recording medium and the take-up lobe are attached to and removed from the apparatus in a cassette type. When the cassette is removed from the device for inspection or to clear paper jams during use of the device, and then the cassette is reinstalled to feed photosensitive recording media, the used photosensitive recording media will be removed from the take-up roller. Unless the medium is removed, it is impossible to feed the photosensitive recording medium using the leader tape, which poses a problem in that the operation is very troublesome.

Furthermore, if the take-up roller with the display section is damaged or lost when refeeding the photosensitive recording medium, it will be impossible to reread the characteristic information of the photosensitive recording medium.
There is also a problem in that it is necessary to input characteristic information of the photosensitive recording medium by cumbersome key operations, etc., and the operations are very troublesome and input errors are likely to occur.

The present invention has been made in view of the problems that exist in the conventional technology, and its purpose is to provide a method in which a take-up roller is attached to a storage container for a photosensitive recording medium. If the photosensitive recording medium and take-up roller are configured as a cassette and can be inserted into and removed from the device, the cassette may be removed from the device during use for inspection or to clear paper jams, etc., and then removed again. When feeding a photosensitive recording medium with a cassette installed, there is no need for the troublesome work of removing the used photosensitive recording medium from the take-up roller, and a new take-up roller can be used for replacement. In addition, even if the take-up roller, which is equipped with a characteristic information display section, is damaged or lost, the characteristic information of the photosensitive recording medium can be easily displayed using the leader tape. An image forming device that can validate the characteristic information read on the display section of the take-up roller before replacement by reading the display section of the replacement take-up roller without having to re-enter through key operations etc. Our goal is to provide the following.

[Means for Solving the Problems] In order to achieve the above object, the present invention includes an exposing means for exposing a long photosensitive recording medium to form a latent image, and developing the latent image after exposure. a winding roller for winding up the photosensitive recording medium after use; a display section attached to the outer peripheral surface of the winding roller for indicating characteristic information of the photosensitive recording medium; and a display section for reading the display section. In the image forming apparatus, the image forming apparatus is provided with a reading unit for controlling the volume, and a control unit for changing the settings of image forming conditions such as exposure and development based on the characteristic information of the photosensitive recording medium read by the reading unit. A replacement take-up roller is prepared so that the take-up roller can be replaced during use, and the characteristic information read on the display of the take-up roller before replacement is displayed on the outer circumferential surface of the replacement take-up roller. A display section is attached to display information indicating activation.

[Function] In the image forming apparatus configured as described above, after loading the photosensitive recording medium into the apparatus, the photosensitive recording medium is placed at a predetermined position of the apparatus through a data plate provided at the starting end of the photosensitive recording medium. When the paper is passed through the conveyance path, as the take-up roller rotates, a display section attached to the outer circumferential surface of the take-up roller faces the reading section multiple times to read characteristic information of the photosensitive recording medium. Then, based on the characteristic information of the photosensitive recording medium read by the reading section, image forming conditions such as exposure and development are set by the control means.

Also, during use of the device, for inspection or to clear paper jams, etc.
After removing the photosensitive recording medium from the device together with the take-up roller, when reinstalling them and feeding the photosensitive recording medium, use a new take-up roller for replacement and record the photosensitive recording with the leader tape. Media can be passed through. Therefore, the troublesome work of removing the used photosensitive recording medium from the take-up roller is not required, and the photosensitive recording medium can be easily and quickly re-fed.

Furthermore, when re-feeding the photosensitive recording medium using this replacement take-up roller, the display section attached to the replacement take-up roller is read by the reading section, and based on the read information. Then, the control means validates the characteristic information read on the display section of the take-up roller before replacement. Therefore,
Even if the take-up roller with the characteristic information display section is damaged or lost, there is no need to perform troublesome operations such as re-entering the characteristic information of the photosensitive recording medium using cumbersome key operations. do not have.
