Abstract

PURPOSE:To load and store the abnormal print output with its secrecy kept by carrying an abnormal recording medium and a recording medium having the normal print output to the loading means set independently of each other. CONSTITUTION:A controller part CON controls totally an electrophotographic process including the transfer of the print information, the feed of forms, the formation of pictures, etc. When a sensor 3 detects the abnormality of a picture recorded on a recording medium, the part CON drives a branch mechanism 7 to identify and carry the recording medium having the abnormal picture to a 2nd form loading part 9. Then the drive of the mechanism 7 is controlled so that a recording medium having a normal picture is sent to a 2nd form loading part 8. Therefore only a specific controller can open and close a door 9c of the part 9. Thus it is possible to avoid such an inconvenient case where the recording medium having an abnormal picture is inadvertently taken to the outside. Then the leakage of the important information can be evaded.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a recording device, and particularly to a recording device that forms an image on a sheet-like recording medium.

[Conventional technology]

Conventionally, in a recording device that forms an image on this type of sheet-like recording medium, an abnormality occurs when an image is not formed correctly on the recording medium due to an abnormality in the conveyance of the recording medium, an abnormality in the formation of the image, etc. The recording medium is guided to a storage means different from the storage means of the recording medium on which the image was normally formed, and the image that was supposed to be formed on the recording medium where the abnormality occurred is again formed on another recording medium. By doing so, a recording apparatus has been used in which the effects of the abnormality do not affect the recording media loaded in the storage means for discharging recording media on which images have been normally formed.

[Problem to be solved by the invention]

However, in conventional recording devices, the recording medium with the abnormality is ejected to a storage means accessible to the operator and discarded, so anyone can easily obtain the discarded printout. Therefore, this situation cannot be said to be favorable from the viewpoint of maintaining the confidentiality of print data.

Particularly in the current information age, from the viewpoint of maintaining the confidentiality of printed data, if printed output is left visible to an unspecified number of people, there is a risk that valuable information will be taken outside.

Recording media with abnormalities are different from regular output, and a dedicated operator is assigned to the print output side to manage the print output so that it is not carelessly transported outside the company. Further, it is necessary to perform a cutting operation to cut the printed output in which an abnormality has occurred into small pieces and discard it, and there are problems in print output management, such as having to perform complicated processing for each abnormal printed output.

In the future, in a system in which one printing device is shared by multiple departments, the above problem will occur frequently and may become a factor that significantly impedes printing processing efficiency.

This invention was made in order to solve the above problem, and detects the occurrence of printing abnormality on a recording medium being conveyed, and detects the recording medium recognized as abnormal and the record determined to have normal print output. It is an object of the present invention to provide a recording device that can load and store abnormal print output while ensuring confidentiality by conveying the media to a separately provided loading means.

[Problem to be solved by the invention]

The recording device according to the present invention includes an abnormality detection means for detecting an abnormality in a recorded image of a recording medium, a plurality of loading means for loading recording media on which images are recorded, and an abnormality image based on a printing abnormality detection state by the abnormality detection means. Alternatively, the apparatus is provided with a conveyance control means for identifying and conveying each recording medium that will produce a normal image to each stacking means.

In addition, a jacket that hides the recording medium loaded on one of the loading means that caused the abnormal image, an ejection mechanism that takes out the recording medium hidden in this jacket, and a locking mechanism that locks and unlocks this ejection mechanism. It may be provided.

(Operation) In this invention, when an abnormality in the recorded image of the recording medium is detected by the abnormality detection means, the conveyance control means identifies and conveys the recording medium with an abnormal image to one of the stacking means, and records the recording medium with a normal image. The medium is identified and conveyed to the other loading means.

In addition, the loading means for loading the recording medium with the abnormal image is hidden by the jacket, and the ejection mechanism is opened by the lock mechanism, so that the recording medium with the abnormal image loaded on the loading means can be taken out of the jacket. do.

〔Example〕

FIG. 1 is a cross-sectional view showing the configuration of a recording apparatus according to an embodiment of the present invention. Reference numeral 1 denotes a paper feed mechanism that loads and feeds paper, which is a sheet-shaped recording medium to be printed.

A transport path 2 transports the paper fed from the paper feed mechanism 1. Reference numeral 3 denotes a sensor that detects conveyance abnormalities such as double feeding and skew feeding of sheets on the conveyance path 2. A photosensitive drum 4 forms a toner image to be transferred onto paper by an image forming mechanism (not shown). 5
A transfer charger transfers the toner image on the photosensitive drum 4 onto a sheet of paper on the conveyance path 2. A fixing device 6 fixes the toner image transferred onto the paper using heat and pressure. Reference numeral 7 denotes a branching mechanism that switches the discharge destination of the paper after the image fixing process has been completed. 8 is a first paper stacking section serving as a stacking means, and the image is transferred and fixed normally (if no abnormality is detected by the sensor 3 or a light amount error BD error (detected by a sensor not shown) necessary for print formation occurs. ) Load only sheet-shaped recording media.

Reference numeral 9 denotes a second paper stacking section, in which the branching mechanism 7 distributes paper with abnormal printing when an abnormality is detected by the sensor 3, an error in the amount of light required for print formation, or a BD error (detected by a sensor not shown) occurs. It is composed of a jack 9a for concealed loading and storage, a loading section 9b, an opening/closing screen 9c (retrieval mechanism) and a locking mechanism 9d. In addition, the lock mechanism 9
The key to lock or unlock d is limited to a specified operator. CON is a controller section that also serves as a conveyance control means, and controls the electrophotographic process such as sending and receiving print information, paper conveyance, and image formation. Then, the branching mechanism 7 (consisting of a direction control mechanism such as a flapper) is driven in order to identify and convey the recording medium with the abnormal image to one of the second paper stacking sections 9, and
The driving of the branching mechanism 7 is controlled so that the recording medium that will be a normal image is identified and conveyed to the first paper stacking section 8.

FIG. 2 is a control block diagram illustrating the configuration of the controller unit CON shown in FIG. Perform analysis, etc.

A page buffer 11 stores print data analyzed by the CPU 10 in units of pages.

12 is a printer interface, and page buffer 11
The image data stored in the CPU 10 is sent to an image forming mechanism (not shown), and the control signals from the printing mechanism such as the sensor 3 to the human power signal bifurcation mechanism 7 etc. are transferred between the CPUs 10 and 10. A print pointer 13 indicates a page to be printed or is being printed among the pages on the page buffer 11 .

Next, the printing control operation according to the present invention will be explained with reference to FIG.

FIG. 3 is a flowchart illustrating an example of a printing control procedure according to the present invention. Note that (1) to (9) indicate each step.

When printing starts, the CPU 10 performs initialization such as setting the first page of the page buffer 11 in the print pointer 13 (1). Next, it is determined whether the printing has ended, that is, whether the data has been completed and all of the page buffer 11 has been printed. 2) If YES, the printing ends; if NO, the CPU 10 sends the paper to the paper feed mechanism 1 via the printer interface 12. Command paper feeding (3) Next, determine whether there is an abnormality in paper conveyance based on the signal of sensor 3, etc. 4) If no, the page on page buffer 11 indicated by printer pointer 13 is sent via printer interface 12. The image is sent to the image forming mechanism and printed on paper (5) At this time, while the printer interface 12 is transferring the image, the page buffer 11
Create a page up.

Next, a command is sent to the branching mechanism 7, and the printed paper is
The output is branched to the first paper stacking section 8, which is the stacking location for normally output paper (6). Also, the print pointer is updated to set the next page to be printed on the page buffer 11 in the print pointer 13. (7) Return to step (2).

On the other hand, if the determination in step (4) is YES, that is, if the sensor 3 detects a conveyance abnormality, printing is not performed and a wait operation is performed for the printing time of one page in order to prevent unnecessary toner consumption. (8)
During this time, creating a page on the page buffer 11 is similar to step (5).

Next, when the predetermined wait process is completed, the paper with the abnormality arrives just before the branching mechanism 7, so by issuing a command to the branching mechanism 7, the same paper is branched and outputted to the second paper stacking section 9. (9). Then proceed to step (2),
Executes reprinting of print information that could not be printed due to a transport error.

In this way, the conveyance of the recording medium to the first paper stacking section 8, which causes printing defects due to sudden abnormality in conveyance or the like, is prevented, and it is possible to obtain printed output without page disturbance.

Furthermore, even if an abnormality occurs in the printed image that results in an abnormal image, only a specific administrator will be able to open and close the opening/closing door 9C of the second paper stacking section 9, so the printed image will become abnormal. It is possible to avoid a situation where the recording medium is carelessly taken outside, and it is possible to prevent leakage of important information.

In the above embodiment, a case has been described in which the identification transport and loading is executed based on the transport abnormality of the recording medium detected by the sensor 3. By restricting the start of printing based on the condition, it is also possible to increase the security reliability of the layer.

[Effects of the Invention] As explained above, the present invention includes an abnormality detection means for detecting an abnormality in recorded images on a recording medium, a plurality of loading means for loading recording media on which images are recorded, and a printing abnormality detection method using the abnormality detection means. A conveyance control means is provided that identifies and conveys each recording medium with an abnormal image or a normal image to each loading means based on the state, so that the recording medium with an abnormal printed image and the recording medium with a normal printed image are separated from each other. can be identified.

In addition, a jacket for concealing the recording medium loaded on one of the loading means, an ejection mechanism for taking out the recording medium hidden in this jacket, and a locking mechanism for locking and unlocking this ejection mechanism are provided. During printing processing based on important print information from the host, important print outputs that cause print image abnormalities can be stored in a hidden state at all times, and opening and closing of the ejection mechanism can be restricted to specific persons. . Therefore, it is possible to strictly prohibit the removal of printed output due to an abnormality that occurs during image formation on a recording medium, thereby achieving an excellent effect of preventing leakage of confidential information.
