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 or an abnormality in the formation of the image. The recorded medium is routed to a storage means different from the storage means for the recording medium on which the image is normally formed. Then, by re-forming the image that would have been formed on the recording medium on which the abnormality occurred on another recording medium, the influence of the abnormality can be removed by ejecting the recording medium on which the image was normally formed. The recording media loaded in the storage means to be stored are prevented from reaching the recording media.

(Problem to be Solved by the Invention) However, with conventional recording devices, the recording medium in which the abnormality has occurred is ejected to a storage means accessible to the operator and discarded, so it is difficult to maintain the confidentiality of printed data. was difficult.

Moreover, since the recording medium in which the abnormality has occurred is not a regular output, even if it is carelessly taken outside the company, the data content cannot be determined by the side receiving the printed output. For this reason, a full-time operator is required to monitor this, or the person receiving the printed output has to take the trouble to monitor it, which has been an obstacle to the shared use of the recording device ffi.

Furthermore, recording media in which an abnormality has occurred must be disposed of using a shredder or the like, which is a burden on the operator.

The present invention was made to solve these conventional problems, and an object of the present invention is to provide a recording device that can prevent confidential information from being leaked from a recording medium that has abnormalities in conveyance or image formation. .

[Means to solve the problem]

The recording device according to the present invention automatically discharges a recording medium with an abnormality detected by a means for detecting an abnormality in image formation on the recording medium such as a conveyance abnormality to a destination equipped with a shredder mechanism. It was designed to be chopped up and disposed of.

[Effect]

According to the recording device of the present invention, since a recording medium in which an abnormality has occurred in image formation is automatically shredded, the print data on the recording medium in which the abnormality has occurred is not inadvertently disclosed to the outside. It is possible to satisfy the requirement of maintaining m-tightness.

〔Example〕

An embodiment of the present invention will be described below based on the drawings.

FIG. 1 is a schematic diagram showing an electrophotographic printer which is an embodiment of the present invention.

In the figure! is a paper feed mechanism that feeds the paper that is a sheet-like recording medium to be printed, 2 is a conveyance path that conveys the paper fed from this paper feed mechanism 1, and 3 is the paper on this conveyance path 2. double shipping.

A sensor detects conveyance abnormalities such as skew, a drum 4 forms a toner image to be transferred to paper by an image forming mechanism (not shown), and 5 transfers the toner image on this drum 4 to the paper on the conveyance path 2. a transfer band Tt device for transferring; 6 a fixing device for fixing the toner image transferred onto the paper with heat and pressure;
7 is a branching mechanism that switches the output destination of the paper after fixing the image;
8 is the first paper 8 on which the paper on which images have been printed normally is loaded.
I, it part, 9 is a shredder (second paper stacking part) that shreds paper in which an abnormality has occurred. Switching the output destination of the paper after image fixation, that is, switching between discharging the paper to the first paper stacking section 8 or discharging it to the shredder 9, is as follows:
This is done by the branching mechanism 7.

FIG. 2 is a control block diagram of an embodiment of the present invention. In the figure, 10 is for controlling the entire printer system,
A CPU that analyzes print data input from a data input mechanism (not shown); 11 a page buffer that stores print data analyzed by the CPU in page units; 12 a page buffer (not shown) that stores image data stored in the page buffer 11; In addition to sending control signals to the image forming mechanism such as the sensor 3 and the input signal 1 from the printing mechanism such as the sensor 3 to the branching mechanism 7, etc.
A printer I/F 13 interposed between the PU10 and the printer I/F 13 prints out of the pages on the page buffer 11.
It is also a print pointer that indicates the page that is being printed.

Next, the operation of one embodiment of the present invention will be explained using the flowchart of FIG. 3 showing print control.

When printing starts, cputo performs initialization such as setting the first page of the page buffer 11 in the print pointer 13 (step 1).

Next, determine whether printing is finished (step 2).
). Printing is completed when the data is completed and all of the page buffer 11 is printed. If printing is not completed, the CPU 10 instructs the paper feed mechanism 1 to feed paper via the printer I/FIZ (step 3).

In the next step 4, it is checked from the signal of the sensor 3, etc. whether there is any paper conveyance abnormality. If there is no abnormality, the page on the page buffer 11 indicated by the print pointer 13 is sent to the image forming mechanism via the printer I/F 12 and printed on paper (step 5). At this time, the printer I/F 12 creates a page on the page buffer 11 while transferring the image.

Next, a command is sent to the branching mechanism 7 to send the printed paper to the first paper stacking section 8, which is the stacking location for normal output paper (step 6).

Also, set the next page to be printed on the page buffer 11 in the print pointer 13 in step 7.
), return to step 2.

If the sensor 3 detects a conveyance abnormality in step 4, printing is not performed and a wait operation is performed for the printing time of one page in order to prevent unnecessary consumption of toner (step 8). During this time, creating a page on the page buffer 11 is the same as in step 5.

After the wait in step 8, the paper with the abnormality reaches the branching mechanism 7, so by issuing a command to the branching mechanism 7, the paper is sent to the shredder 9 (step 9)
. The shredder 9 works in conjunction with the branching mechanism 7 to shred the abnormal paper. Next, the process proceeds to step 2, in which the printer that was unable to print due to the transport abnormality prints again.

In this way, it is possible to prevent the effects of sudden conveyance abnormalities from affecting the output of the first sheet & [copy 8, and to obtain output without page disturbances. On the other hand, a recording medium in which an abnormality has occurred is automatically shredded by a shredder 9. For this reason,
This eliminates the inconvenience in terms of security protection, such as print data on a recording medium in which an abnormality has occurred being inadvertently leaked to the outside.

(Effects of the Invention) As described above, according to the present invention, recording media with abnormalities in image formation are automatically shredded. Device leakage from the medium can be prevented.
