To suppress occurrence of a reading error even when recording a one-dimensional code image in which a plurality of bars is arrayed in a scanning direction.SOLUTION: A liquid discharge device (printer) 10 comprises: a recording head 62; a scan mechanism 6; a conveyance mechanism 7; and a control unit 8. When a one-dimensional code image 100 is formed on a sheet 9 in a direction where an extending direction and a scanning direction match each other, the control unit 8 executes the division recording processing of controlling the recording head and the scan mechanism 6 such that a plurality of first portions 111 whose positions with respect to the conveyance direction are the same in a plurality of recording regions 100a, is recorded at the forward movement of the recording head 62 in the scanning direction, and a plurality of second portions 112 being the plurality of second portions 112 whose positions with respect to the conveyance direction are the same in the plurality of recording regions 100a and whose positions with respect to the conveyance direction are at least partially different from those of the plurality of first portions 111 is recorded at the return movement of the recording head 62 in the scanning direction performed without the conveyance processing after the forward movement.SELECTED DRAWING: Figure 5 【課題】走査方向に複数のバーが配列された一次元のコード画像を記録する場合であっても、読み取りエラーの発生を抑制する。【解決手段】液体吐出装置（プリンタ）１０は、記録ヘッド６２と、走査機構６と、搬送機構７と、制御部８とを備えている。一次元コード画像１００が、伸長方向と走査方向とが一致する向きに用紙９上に形成される場合、制御部８は、複数の記録領域１００ａにおいて搬送方向に関する位置が互いに同じである複数の第１部位１１１が、記録ヘッド６２の走査方向への往動時に記録され、複数の記録領域１００ａにおいて搬送方向に関する位置が互いに同じである複数の第２部位１１２であって、複数の第１部位１１１とは搬送方向に関する位置が少なくとも一部において異なる複数の第２部位１１２が、往動後に搬送処理を経ることなく行われる記録ヘッド６２の走査方向への復動時に記録されるように、記録ヘッド及び走査機構６を制御する分割記録処理を実行する。【選択図】図５
