<upd_detl>My understanding is that this word.is only.used specifically for Japanese-style　cropmarks (the 角トンボ especially resembles a  dragonfly). Adobe Illustrator has a specific "function" or shortcut for.implementing.these:
https://helpx.adobe.com/illustrator/using/specify-crop-marks-trimming-or.html
"Use Japanese-style crop marks
Japanese-style crop marks have double lines, which visually define a default bleed value of 8.5 points (3 millimeters).

Choose Edit &gt; Preferences &gt; General (Windows) or Illustrator &gt; Preferences &gt; General (Mac OS).
Select Use Japanese Crop Marks, and then click OK."

Not sure this should be two senses, I feel like it's really one sense that encompasses both symbols (cobsidering the existamnce of words like センタートンボ and コーナートンボ)</upd_detl>

kokugos only seem to have 1 def, and they only specify the センタートンボ (十字)</upd_refs>
