ることができる。When performing double-sided recording by the laser printer described above, first, the upper body 10a is rotated counterclockwise in the figure with the shaft 11 shown in FIG. 1 as a fulcrum to easily remove the discharge tray 50. Therefore, the upper main body 10a is opened. Then, the latches 51b and 51c and the screw 53
And the paper ejection tray 50 is removed from the openings 36a and 36b. Then, as shown in FIG. 8, the double-sided recording device 55 is placed on the mounting portion 31 in place of the discharge tray 50, and the signal connector 46 / power supply connector 47 of the device main body 10 and the signal connector / power supply connector of the double-sided recording device 55 are placed. And are respectively connected. After that, a latch is applied and a screw is screwed in to mount the double-sided recording device 55, and after closing the openings 36a and 36b,
The upper main body 10a is closed and the sheet conveying direction is switched to the arrow D direction in FIG. 8 by the switching guide. Then, the paper 18 on which one side has been recorded is ejected from the ejection port 35 to the insertion port 55a by the ejection roller 29.
Then, the sheet is conveyed to the sheet conveying path 57, and most of the sheet 18 is once sent out from the projecting port 55c by the switchback roller 62. After that, the switchback roller 62 is reversed to guide the paper 18 to the switchback transport path 63,
It is switched back as shown by arrow E in FIG. 8, and is further re-fed to the photoconductor 12 in the apparatus main body 10 by the conveyance roller 64 through the delivery port 55d and the re-feed port 38. Then, recording is also performed on the other surface (upper surface) of the paper 18. Even when the double-sided recording device 55 is mounted as described above, when the double-sided recording is not performed on the sheet 18 and the sheet 18 is discharged as it is after the single-sided recording,
After the sheet conveying direction is switched to the arrow F direction by the switching guide, the single-side recorded sheet 18 can be ejected onto the sheet ejection section 58 from the sheet ejection port 55b by the sheet ejection roller 59 through the sheet ejection path 56.
