Recording apparatus, method of transporting recording medium, and liquid ejecting apparatus

Abstract

The present invention provides a recording apparatus capable of improving throughput when the stop position of a recording material at the start of recording is set differently. The control unit has a plurality of speed level information (V3-V1) as the rotation speed of the above-mentioned conveying roller, has a plurality of recording patterns for the blank at the leading end, and has information (P1-P3) of recording start positions that are different for each recording pattern. , with an optimal transport speed selection mechanism (80b), if any one of the recording modes is selected, the first distance (L1-L3) from the recording material sensor (14) to the recording start position, and the temporary selection Compared with the second distance (M1-M3) that the conveying roller (19) that rotates at a speed level transmits the recording material during the deceleration process, under the condition that the second distance is shorter than the first distance, the number of the above-mentioned conveying rollers should be selected The fastest speed level among the speed levels.

Description

technical field [0001] The present invention relates to a nozzle opening row, equipped with a recording head that performs recording in a recording material, a conveying roller that conveys the recording material to a position facing the recording head, and a device for including the above-mentioned recording head and a conveying roller. A recording device, a recording material conveying method, and a liquid ejecting device of a control section that control the recording execution of each operation of the roller. Background technique [0002] Here, the liquid ejecting apparatus refers not only to an inkjet type recording apparatus, a copier, and a recording apparatus such as a facsimile machine that ejects ink from a recording head as a liquid ejecting head to a recording medium such as recording paper, and performs recording on the recording medium. It includes a device that uses a liquid corresponding to a specific application instead of ink, and ejects from a liquid eject...

AI Technical Summary

Problems solved by technology

[0011] However, in the former prior art (Patent Document 1), the recording paper is conveyed at the same speed regardless of whether the stop position is different, so the throughput cannot be sufficiently improved.

In particular, when stopping at the stop positions P2 and P3 other than the stop position P1 closest to the sensor detection position, the improvement in processing capacity is insufficient.

[0012] In addition, in the latter prior art (Patent Document 2), since the paper conveying speed is variable, an improvement effect of processing capacity can be expected, but since the paper conveying speed is determined according to the value of the upper margin of the paper, the paper conveying speed is When the paper is conveyed at the determined speed, the motor is decelerated when the sensor detects the leading end of the paper. Therefore, as the determined paper conveying speed, when the sensor detects the leading end of the paper, the above-mentioned motor deceleration

[0013] Therefore, when determining the paper transport speed by calculation, there is a problem that the data table used for the calculation is enlarged and the calculation is complicated.

[0014] In addition, in order to start the deceleration of the above-mentioned motor when the front end of the paper is detected by the sensor, the relationship between the position of the sensor and the stop position of the paper is not arbitrary, but an absolute condition, so the design is influenced by the sensor. There is a problem that the degree of freedom of design is reduced due to the restriction that the setting is limited to a narrow range.

[0015] In addition, if the deceleration of the motor is started immediately when the sensor detection is triggered, it is easily affected by the sensitivity of the sensor (time lag, etc.), and there is a problem that the accuracy of the stop position of the paper decreases.
