A new sheet set to be longer than the distance L between the point N1 and the second nip point N2, specifically, a sheet S having a minimum recordable size set in the vertical direction is fed together. It is characterized by discharging.

  The recording material discharging apparatus 1 has a primary detection means 31 and a secondary detection means 32 as constituent members. These two detection means detect whether the paper P or the paper S has passed or remained, and based on the detection information, the paper P or the paper S remaining between the first nip point N1 and the second nip point N2 is detected. The discharge is executed. The recording material discharge method according to the present invention will be described below together with the operation mode of the recording material discharge apparatus 1 according to the present invention in accordance with the flowcharts shown in FIGS.

(1) Feeding start to primary detection (see Fig. 4)
First, when the presence of panel operation or recording execution data is confirmed in step S1, feeding of the paper P or paper S is started in step S2, and in step S3, the primary detection means 31 causes the paper P or paper S to be fed. Detect passage. In step S4, it is determined whether or not the primary detection means 31 is turned on at regular timing. Note that whether or not the timing is correct is determined by whether or not the feeding roller 14 has rotated a predetermined number of steps.

  If it is determined that the primary detection means 31 has been turned on at regular timing, after the paper is fed in step S5, the operation is terminated, and the operation mode based on the detection information of the secondary detection means 32 shown in FIG. Migrate to On the other hand, if it is determined that the primary detection means 31 is not turned on at regular timing, the normal size paper discharge execution controller is activated in step S6, and the paper P or the paper S is discharged.

(2) Secondary detection (see Fig. 5)
Next, in step S7, the numerical value N of the counter of the feeding roller 14 is set to 0, and in step S8, the feeding roller 14 is rotated forward at a predetermined rotational speed. In step S9, the detection of the sheet P or the sheet S by the secondary detection means 32 is confirmed. If the passage of the sheet P or the sheet S is confirmed, in step S10, the sheet P or the sheet prior to the execution of recording. The cue execution controller of S is activated.

  On the other hand, if the passage of the sheet P or the sheet S is not confirmed, a predetermined number of steps sufficient for the feeding roller 14 to deliver the sheet P or the sheet S to the conveying roller 19 in step S11, It is determined whether or not it has been rotated, and if it is determined that it has not rotated for a predetermined number of rotations, the process returns to step S8 and the rotation of the feeding roller 14 is continued.

  If it is determined that the sheet has been rotated by a predetermined number of steps, it is determined in step S12 whether or not the sheet size on the driver is the minimum recordable size, and the sheet S is determined to be the minimum recordable size. In this case, the discharge execution controller for the minimum recordable size shown in FIG. 6 is activated. On the other hand, if it is determined that the sheet S is not the minimum recordable size, an error is displayed in step S13, and processing is performed according to the discharge execution controller when the normal size sheet P remains.

(3) Execution of discharge (see Fig. 6)
First, in step S14, the user issues an instruction to set a new minimum recordable size paper S in the vertical direction, sets it in step S15, and turns on the paper feed button in step S16. Then, the feeding roller 14 and the conveying roller 19 are activated at the same time, and the feeding roller 14 is rotated by one rotation.

  Next, in step S18, the secondary detection means 32 confirms the presence or absence of the sheet S, and if it is confirmed that there is the sheet S, in step S19, the remaining sheet S is discharged as it is and is newly oriented vertically. The cueing execution controller is activated in order to cue the recording position prior to the start of recording.

  On the other hand, when the secondary detection unit 32 determines that there is no paper S, the transport roller 19 is rotated forward in step S20, and the process returns to step S18 to determine the presence or absence of the paper S by the secondary detection unit 32. The
