摘要： PROBLEM TO BE SOLVED: To improve the through put by arranging a separated sheet feed means to separate and carry duplicate-fed sheets when the sheets are duplicate- carried from a sheet loading means in the vicinity of a sheet discharge end of the sheet loading means to reduce the distance to an image forming means to form an image. SOLUTION: A plurality of recording papers 6 are placed in a nip part 9 with their self weight in a waiting condition, and fed one by one by the separating effect between a sheet feed roller and a pinch roller 2 by the rotation of a sheet feed roller 16 when the printing instruction is received. That is, a plurality of recording papers 6 enter between the pinch roller 2 and the sheet feed roller 16, and the pinch roller 2 is rotated in the reverse direction to the sheet feeding direction. When only one recording paper 6 is present between the rollers 2, 16, the pinch roller 2 is driven through the recording paper 6 to be carried by the sheet feed roller 16 into a regular recording paper carrying operation. Then, the recording paper 6 is recorded by a printing part 29, and discharged through a discharge roller 32.

摘要： PURPOSE:To obtain a low-cost recorder in which a structure is simplified by stacking record sheets in a stacker out of a guide member by own weight after a lower end of the sheet is passed through a discharge means. CONSTITUTION:A record sheet 10 conveyed while tension is being applied between a discharge roller 13 and a sheet feed roller 22 is discharged while being supported by a sheet discharge guide 25 provided slightly at a left side from a central axis of a lateral direction of the sheet 10 under the roller 13. The sheet 10 is not dropped to a stacker 20 where the discharged sheet 10 is stacked while being interposed between the roller 13 and a pulse wheel 14. Accordingly, the sheet 10 being discharged is not brought into contact with a recording surface of a recorded sheet 10b already stacked in the stacker 20. However, when the conveyance is advanced and the lower end of the sheet 10 is removed out of the roller 13 and the wheel 14, the sheet 10 is slid out of the member 25 by own weight of the sheet 10, dropped to the stacker 20 and stacked in the stacker 20.

摘要： PURPOSE:To automatically carry out the end setting of the second sheet and after by reversely feeding only the second sheet and detecting the front end thereof after finishing the recording of the first sheet and, after that, simultaneously carrying the discharging of the first sheet and the front edge projectioning of the second sheet. CONSTITUTION:After finishing the recording of the first sheet 5 (at this time, the rear end of the first sheet and the front end of the second sheet are placed, e.g., in a position P), a feed roller 7 is reversely rotated (a discharge roller 10 is kept stopped) to reversely feed only the second sheet 5 by a distance A+alpha (alpha=a small amount) which exceeds a distance A. Thereby, the second sheet 5 is sent back until the front end thereof is positioned on the upper course side of a sheet sensor 20 and, after the front end is detected by the sensor 20, the roller 7 is normally rotated while the discharge roller 10 is also simultaneously normally rotated with the same conveying quantity, to simultaneously carry out the discharge of the first sheet 5 and the end setting (to set in the starting position of printing) of the second sheet 5.

摘要： PURPOSE:To accurately control the position of a sheet feed roller even in a specific mode performed by the reversal driving of the sheet feed roller, by stopping the delivery roller of a cut sheet feeder at the time of the recording of a specific printing mode shifting a sheet to a feed direction to perform printing plural times. CONSTITUTION:At the time of the recording of a specific mode shifting a sheet 5 to a feed direction to perform printing plural times, control is performed so as to stop the delivery roller 11 of a cut sheet feeder 8. The stop of the delivery roller 1 is performed by temporarily stopping a feeder motor 9. After the finish of the printing of the specific mode, it is necessary to once return the sheet to the start position of line feed operation, that is, a non-shifted normal position but, in returning the sheet 5 to the normal position, a sheet feed roller 1 is once subjected to excessive return rotation and subsequently rotated to an advance direction to remove the effect of the backlash of a sheet feed transmission mechanism. By this method, the rotary position of the sheet feed roller 1 can be controlled accurately and the printing quality of specific mode printing can be enhanced.

摘要： PURPOSE:To improve the discharging and receiving properties of a variety of sizes of sheets by adjusting the attaching position of a sheet support member provided on a stacker for receiving the discharged sheets according to the width of the discharged sheet. CONSTITUTION:An automatic sheet feeder U' has a hopper 2 and a stacker 3. A sheet discharge guide 20 is disposed in the stacker 3. In the central portion of the guide 20 are provided fit holes 21a, 21b with a pitch P equal to the width of legs 11', 11' of a discharged sheet support 11, and further a spare fit hole 21c adjacent one fit hole 21b is provided in a position corresponding to the same pitch. And the sheet support 11 is fitted in the holes 21a, 21b or 21b, 21c according to the width dimension of discharged sheet. Thus, the discharging and receiving properties of sheets having respective sizes can be improved without increasing the number of parts.

摘要： PROBLEM TO BE SOLVED: To eliminate the deterioration of separating feed performance and reduce the effects of back tension in a simple constitution. SOLUTION: When a sheet supported by a pressure plate 4 to press abut to a paper feed roller 1 is fed out to be separated sheet by sheet by a separating pad 6, the pressure plate 4 is separated from the paper feed roller 1 when the sheet is separated, after the separated sheet is conveyed by a conveying means in the downstream, the separating pad 6 is separated from the paper feed roller 1, and also, a relative angle of the separating pad 6 to a sheet on and after the second is changed so as to be larger than an angle initially set for a separating feed. In this way, back tension of the conveyed sheet can be decreased, and the double feed of the sheet also can be surely prevented.

摘要： PROBLEM TO BE SOLVED: To provide a picture image recorder having a conveyance means which can convey both of a single sliplike medium to be recorded and a long medium to be recorded (for example, cut paper and fan fold paper) properly. SOLUTION: When a cut paper is conveyed, each of a pinch roller 11, an auxiliary roller 16, and a needle roller 12 is brought into pressure-contact with a conveyance roller 10. At this time, a guide member 26 is set in such a manner that a part of the conveyance roller 10 is knotched and each pressure-contact part is set in such a manner that a projection part is not formed for a diameter of the conveyance roller 10. Moreover, when continuous paper is conveyed, the pinch roller 11 and the auxiliary roller 16 are apart from the conveyance roller 10 completely, and pressure-contact force of the needle roller 12 is reduced. Furthermore, continuous paper is conveyed on a projection part as a protruding part for the conveyance roller 10 of the guide member 26.
