To provide a technology for adequately executing processing for determining whether electrical connection is adequately carried out between terminals.SOLUTION: A recording device includes a recording device main body 201 on which a recording head 300 is detachably mounted. A power supply part 406 arranged on the recording device main body 201 includes power supply control means 405 which selectively sets a mode out of a plurality of modes including a normal operation mode, in which a maximum suppliable current value to a power supply input terminal 131 is a first value, and a current restriction mode, in which the maximum suppliable current value to the power supply input terminal 131 is a second value smaller than the first value, to the power supply part 406. In a state that the current restriction mode is set by the power supply control means 405, an electrical connection state between a ground connection terminal 108 of the recording head 300 and a ground terminal 213 of the recording device main body 201 is determined on the basis of a detection voltage applied to a first diode 109 of the recording head 300.SELECTED DRAWING: Figure 5 【課題】端子間で電気的な接続が適切に行われているかどうかを判定する処理をより適切に実行する技術を提供する。【解決手段】記録装置は、記録ヘッド３００を着脱可能に搭載する記録装置本体２０１を有する。記録装置本体２０１に設けられた電源部４０６は、電源入力端子１３１に対する最大供給可能電流値が第１の値である通常動作モードと、電源入力端子１３１に対する最大供給可能電流値が前記第１の値より小さい第２の値である電流制限モードと、を含む複数のモードからいずれかを電源部４０６に選択的に設定する電源制御手段４０５を備える。電源制御手段４０５により電流制限モードが設定された状態において、記録ヘッド３００の第１ダイオード１０９に印加された検出電圧に基づき、記録ヘッド３００のグランド接続用端子１０８と記録装置本体２０１のグランド端子２１３との電気的な接続状態を判定する。【選択図】図５
