Abstract

PURPOSE:To utilize a space, where a storage device is situated, as a shifting space for a guide plate as well as to aim at the miniaturization of a device by supporting the guide plate so as to make it shiftable up to a position where the storage device is situated. CONSTITUTION:When a sheet S is jammed, an operator pulls a cassette 3 toward himself from a device body 2, then a guide plate 27 is turned round to a position where the cassette 3 is situated counterclockwise against spring force of a spring 30, and the jammed sheet S is removed therefrom. And, the guide plate 27 is turned round clockwise by the spring force of the spring 30, putting it back to the specified position. In addition, the cassette 3 is attached to the device body 2 and thus jam handling is over. And, for jam recovery, the sheet S whose one side is printed is conveyed to a refeeding route 19, and it is further conveyed to a refeeding roller pair 25 by each pair of feed rollers 20, 21 and 22, 23.

Since the present embodiment has the above-described configuration, when the laser beam printer 1 obtains image information from an external device, the image information is emitted from a laser emitting unit (not shown).
Then, the image forming section 9 is exposed to light by the laser scanner section]0. Next, the image forming section 9 forms an image by exposure. At this time, the sheet 1-S is fed from the cassette 3 by a paper feed roller 5, and further conveyed by a pair of conveying rollers 6 to a pair of registration rollers 7. And sea 1-
The sheet S comes into contact with the register 1-roller pair 7 and is corrected for skew, and is conveyed to the image forming section 9 in synchronization with the image on the image forming section 9 . Next, the image forming section 9 prints an image on the sheet 1-S, and the sheet 1-S is further transferred to the fixing device 12 by the conveying section 11.
transported to. The sheet 1-8 has an image fixed thereon by the fixing device 12, and is conveyed to the flapper 15 by a pair of conveying rollers 13. At this time, when the laser beam printer 1 is in the single-sided printing mode, the sheet S is guided by the flapper 15 to a pair of discharge rollers 16, and further discharged to a discharge I-lay 17 by the pair of rollers 16. On the other hand, L
When the double-sided printing mode is instructed to the 2-zer beam printer 15, the sheet 1-S is guided to the refeed path 19 by the flapper 5, and is held between the pair of conveying rollers 20, 21, 22, and 23. transported. At this time, sea 1-
If S jams, the operator pulls out the cassette 3 from the main body 2 of the device, and then moves the guide plate 27 counterclockwise against the spring 30 (opposite the
Sea 1- which rotated to the position where it was located and jammed.
Remove S (see Figure 2). Then, the guide plate 27 is rotated clockwise by the spring force of the screw 30 and returned to the predetermined position.Furthermore, the cassette 3 is attached to the main body 2 of the apparatus to complete the jam removal. Therefore, by the same operation as described above, the sheet S with printing on one side is conveyed to the refeeding path 19, and further conveyed by the pair of conveying rollers 20,
It is conveyed to a refeed roller pair 25 by 21, 22, and 23. Next, the sheets 1-S come into contact with the pair of rollers 25 to correct the skew, and when an image feed signal is issued from an external device, the sheets 1-S are brought into contact with the pair of re-feeding rollers 25 to correct the skew. Re-sent to vs. 7. So()te, sea 1
- S is printed on the back side by the same operation as described above and is ejected to paper ejection 1/sheet 17.
