- the roll paper feeding device of the image forming apparatus is configured such that when the recording paper of the roll body 20 runs out during the image forming process, the last remaining recording paper piece is removed from the roll unit R. If it is longer than the first standard so that it can be conveyed inside and outside the same area, it is ejected and transported.If the length of the remaining recording paper is slightly shorter than the first standard, the leading end of the remaining recording paper is rolled. If the length of the remaining recording paper is shorter than the second standard so that it cannot be conveyed inside the Coulunit R, the remaining recording paper is rolled over by reverse transport. Since it is dropped into the RU to facilitate removal of the remaining recording paper pieces, the process of removing the remaining recording paper pieces can always be performed well, and copying as an image forming apparatus can be performed. Machine reliability It is possible to improve.
- the roll paper supply device of the image forming apparatus when the recording paper of the roll body 20 runs out in the middle of the image forming process, removes the last remaining recording paper piece from the roll unit. If the length is longer than the standard length that can be transported inside and outside the RU, discharge and transport are performed.If the length of the remaining recording paper is shorter than the standard, reverse transport is performed and the remaining recording paper is loaded into the roll RU. This makes the removal of the remaining recording paper pieces easy, so that the processing of removing the remaining recording paper pieces can always be performed satisfactorily, and the reliability of the copier as an image forming apparatus can be improved. 3
- the roll paper supply control device 40 has a function of performing a recording paper discharge processing operation as described later when the copy operation is stopped halfway. That is, the roll paper supply control device 40 has a structure as shown in FIG. 5, and has a central processing unit (hereinafter referred to as a CP paper J 4 1 provided with a roll paper supply control device).
- the input section of the section 41 a includes a paper presence sensor 25, a paper feed sensor 27, and a vicinity of the entrance of the resist roller 18, which are arranged near the outlet of the staple body 20.
- a paper detection signal is applied from a resist sensor 26 disposed at the same time, and a control program and the like that define a procedure for transporting and cutting the recording paper, which will be described later, are stored from the R ⁇ I 42. And a read / read signal from the RAM 43 in which various data are stored.
- the output section of the roll paper feeding control section 41a is provided with a feed roller 22 and a drive motor M of a transfer port 23, which constitute the roll paper transfer mechanism described above. and a driver 36 for the drive motor M3 of the resist roller 18 and a driver 35 for the drive motor M2 of the power unit 24 are connected respectively. Accordingly, a drive signal is output to each of the drive drivers 34, 35, and 36 at a predetermined timing.
- the leading end of the recording paper pulled out from the roll body 20 in the transport direction has passed through the cutter 24 (Yes in step 13), it is downstream from the cutter 24 in the transport direction. If the amount of the recording paper protruding is within about 20 mm as an example within the predetermined range according to the present invention (No in step 15), the recording paper is pulled back. (Step 16), the leading end of the recording paper in the transport direction is pulled back to the front side of the cutter 24 (upstream side in the transport direction)-and when the paper feed sensor 27 is turned off by the pullback operation, (Yes in step 17), the transfer operation is stopped (step 18).
- the control operation differs as follows depending on whether or not the amount of protrusion from the cutter 24 is a transportable length.
- the distance between the resist roller 18 and the transport opening roller 23 is set to the longest distance between the rollers in the transport path, the distance between the resist roller 18 and the transport roller 23 is reduced. If there is a protrusion length of 150 mm or more, which is a little longer than the distance between the rollers 23, processing is performed on the assumption that it can be conveyed on the subsequent conveyance path.
- the amount of recording paper pulled out from the staple body 20 according to the present invention is a transportable length
- the protrusion of the chart paper is set to 150 mm or more, and the protrusion of the chart paper from the cutter 24 is 150 mm or more (Yes in step 19)
- the recording paper is immediately cut (step 20).
- the cut recording paper is discharged toward the discharge tray 13 (step 21), and the processing is performed. Complete.
- the amount of the recording paper protruding from the cutter 24 is less than 150 mm, that is, the amount of the recording paper pulled out from the mouthpiece 20 according to the present invention is equal to the transportable length. If the amount is an example that is not the case (No in step 19), then it is impossible to transfer on the subsequent transfer path, so that it is 150 mm.
- the recording paper is further fed by the amount that is not enough for the cutter (Step 22) :: When the amount of protrusion from the cutter 24 reaches 150 mm (Step 1) (Yes in 9), the recording paper is immediately cut (step 20), and the cut recording paper is discharged toward the discharge tray 13 (step 21).
- step 27 If the recording paper runs out of the roll body 20 during the second discharging operation, after the operation is stopped, the process returns to the above-described step 11 and a message indicating that there is no paper is displayed (step 27).
- step 12 when the leading end of the recording paper pulled out from the roll body 20 in the transport direction has already reached the register sensor 26 (Yes in step 12), A substantially similar discharge process is performed. However, in this case, if a size equal to or smaller than A3 size is specified, it means that the cutting by cutter 24 has already been completed, and if the cutting has been completed (see step 23) Y es), the chart paper is ejected immediately (step 24 ) :: — On the other hand, if the size has not been cut (No in step 23), the chart paper is cut Thereafter (step 25), the cut recording paper is discharged toward the discharge tray 13 (step 26) ;
- the roll paper supply control device 40 described above is different from a document conveyance jam and immediately cuts the recording paper when the recording paper itself pulled out from the roll body 20 is in a jam state. It also has a function, and the roll unit RU having the roll body 20 can be easily pulled out from the apparatus main body 1 by cutting the recording paper stopped during transport.
- the recording paper when the leading end of the recording paper reaches the resist sensor 26, the recording paper is effective because the leading end of the recording paper is stopped by being caught by the resist roller 18. Since the paper is cut, it is easy to remove it, and after processing the jammed paper, the leading edge of the recording paper is at the paper feed sensor 27, so that image formation can be resumed immediately.
- the recording paper pulled out from the roll body 20 is minimized for conveyance. Since the paper is cut to the required length and ejected, unnecessary feeding operation of the recording paper is eliminated, and waste of the recording paper is eliminated. Therefore, the copying operation can be performed efficiently and at low cost, and the reliability of the copying machine as an image forming apparatus can be improved.
