This makes it possible to reliably pick up the recording paper without causing paper jam or the like. Further, the position of the movable rib 15B in the paper feed direction of the roller 14B is located downstream of the position of the roller 14A of the movable rib 15A in order to avoid interference with the paper feed roller 142. Thus, when the recording paper is nipped by the paper feed roller 142 and the pad 143a, the leading end of the recording paper at the position of the movable rib 15B in the paper feed direction of the roller 14B (near the paper feed roller 142) is applied to the paper feed roller 142. Since it is pressed, it is more advantageous for paper jam and the like than the roller 14B of the movable rib 15B.

Then, the uppermost recording sheet P is sandwiched between the driven roller 145 and the sheet feed roller 146 and is sent further forward. When the recording paper P reaches the third paper guide 147, the movement of the carriage 151 in the main scanning direction is started. That is, the carriage 151 located at the standby position (home position) reciprocates between both ends of the recording paper P conveyed after leaving the home position. Then, the recording head changes the pressure in the pressure generating chamber by, for example, a piezoelectric element with respect to the recording paper P being conveyed in the sub-scanning direction, and discharges the ink stored in the pressure generating chamber from the nozzle to perform recording. The predetermined recording information is recorded on the paper P.
[0056]
At this time, the scanning timing of the recording head and the ink ejection timing are controlled by a dedicated controller board or the like of the control unit 160, so that highly accurate ink dot control, halftone processing, and the like are executed. Then, the recording paper P is sandwiched between the paper discharge roller 148 and the paper discharge roller 149 and is sent further forward, and the recording paper P on which recording is finally completed is discharged onto the stacker 110. Thus, recording on the recording paper is completed. Next, printing on the surface of the optical disk will be described.

First, in the standby state, the auxiliary tray 130 is located at the standby position A shown in FIGS. When the user presses the tray eject button, the drive motor 171 of the transport drive section 170 rotates forward to drive at a constant speed. Subsequently, the auxiliary tray drive motor 191 rotates forward to perform constant speed drive. As a result, the auxiliary tray 130 starts to move, and in synchronization with this, the recording head and the sheet discharge roller 148 move from the first arm 193 via the second arm 194.
[0058]
Then, the auxiliary tray 130 starts moving from the standby position A, and as shown in FIG. 18, the tip of the auxiliary tray 130 contacts the roller 14A of the movable rib 15A (the roller 14B of the movable rib 15B). Then, the roller 14A (the roller 14B) rotates upward together with the movable rib 15A (the movable rib 15B) by the force of pushing the auxiliary tray 130 to the downstream side of the conveyance.
[0059]
Further, when the auxiliary tray 130 moves, as shown in FIGS. 19, 20, and 21, the roller 14A (roller roller 14B) rolls on the auxiliary tray 130, and is stored in the auxiliary tray 130 and the auxiliary tray 130. It is possible to prevent the surface of the optical disk D being damaged by the movable rib 15A (movable rib 15B). Then, the driven roller 145 rotates upward together with the frame 12A (frame 12B) by a force that pushes the auxiliary tray 130 to the downstream side of the conveyance. As described above, mutual interference between the auxiliary tray 130 and the first paper guide 141A (first paper guide 141B) can be avoided. Then, the auxiliary tray 130 moves to the disk loading / unloading position B.
[0060]
Thereafter, the auxiliary tray drive motor 191 stops, and the drive motor 171 of the transport drive unit 170 stops. When the user sets the optical disk on the auxiliary tray 130 and presses the tray set button, the drive motor 171 of the transport drive unit 170 rotates in reverse to drive at a constant speed, and the auxiliary tray drive motor 191 rotates in reverse to drive at a constant speed. Subsequently, the center position of the optical disk is detected, the drive motor 171 of the transport drive unit 170 rotates forward to perform constant speed drive, and the auxiliary tray drive motor 191 rotates forward to perform constant speed drive. Then, the auxiliary tray 130 moves from the standby position A to the printing start position by performing the above-described interference avoiding operation, and starts printing on the optical disk.
[0061]
When the printing of the optical disk is completed and the auxiliary tray 130 moves to the disk loading / unloading position B, the user removes the optical disk from the auxiliary tray 130 and presses the tray set button. Then, the drive motor 171 of the transport drive unit 170 rotates in the reverse direction to perform the constant speed drive, and the auxiliary tray drive motor 191 rotates in the reverse direction to perform the constant speed drive. As a result, the recording head and the discharge jagged roller 148 move to their original positions, and the auxiliary tray 130 moves from the disk in / out position B to the standby position A through the paper discharge roller 149 and the paper feed roller 146. Thereafter, the auxiliary tray drive motor 191 stops, the drive motor 171 of the transport drive unit 170 stops, and the apparatus enters a standby state. Thus, printing on the surface of the optical disk is completed.
[0062]
As described above, according to the ink jet printer 100, all processes are performed on the front side from setting of the recording paper P before recording to removal of the recording paper P after recording and further replacement of the ink cartridge 152. Therefore, the operation can be performed quickly and easily, the recording efficiency can be improved, and the peripheral devices can be installed above the printer, so that the work space can be effectively used.
