摘要： PROBLEM TO BE SOLVED: To reduce the number of sheets of a recording medium which records a correction pattern, and correction value determination processes based on the correction pattern while maintaining the correction precision of a conveyance amount of the recording medium in a recorder.
SOLUTION: Recording of the correction pattern is carried out by conveying the recording medium by a U-turn conveyance path. The correction pattern is recorded to a position L1 in LF recording by conveyance of a conveyance roller. The correction pattern is recorded to a position E1 in EJ recording by conveyance of a paper discharge roller thereafter. When the above recording is finished, the recording medium is sent back to an ASF. The recording medium is conveyed by a conveyance path which feeds the recording medium by the ASF, and recording of the correction pattern is carried out. In other words, recording of the correction pattern is carried out to a position L2 in LF recording. Next, the correction pattern is recorded to a position E2 in EJ recording. Thus the correction patterns related to both the U-turn conveyance path and the ASF conveyance path, or a plurality of the correction patterns of the same initial phase related to EJ recording can be recorded to one recording medium.

摘要翻译：要解决的问题：为了减少记录校正图案的记录介质的张数，以及基于校正图案的校正值确定处理，同时保持记录介质在记录器中的传送量的校正精度。解决方案：通过用U形转向传送路径传送记录介质来执行校正图案的记录。校正图案通过输送辊记录在LF记录中的位置L1。此后，通过传送排纸辊将修正图案记录在EJ记录中的位置E1。当上述记录结束时，记录介质被送回ASF。记录介质由ASF传送记录介质的传送路径传送，并进行校正图案的记录。换句话说，校正图案的记录被执行到LF记录中的位置L2。接下来，将校正图案记录在EJ记录中的位置E2。因此，可以将与U转向输送路径和ASF输送路径有关的修正图案或与EJ记录有关的相同起始相位的多个校正图案记录到一个记录介质。版权所有（C）2010，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To lubricate a pinch roller shaft of a sliding part without increasing the size of a recording device nor soiling a recording medium.
SOLUTION: The pinch roller shaft 371 is coated with liquid grease by being singly soaked in quick-drying grease. The pinch roller shaft 371 which is coated with dried grease still having a lubricating component has reduced rotary resistance in regard to a pinch roller 37 and a pinch roller holder 30. Therefore, even a sheet material P having a relatively small friction coefficient can be conveyed without generating variances in conveying lengths. Abrasion of parts due to wear can be greatly reduced.
