PRINTER

To provide a printer capable of detecting contact between a recording medium and a plate member in a more secure manner.SOLUTION: A printer 10 includes a detection mechanism 70 configured to detect contact between a recording medium 5 placed on a table 35 and a plate member 80. The detection mechanism 70 includes: a first rotary shaft 73 connected to a base member 13; a second rotary shaft 74 which is disposed offset in a sub scanning direction X relative to the first rotary shaft 73; a first arm 75 which is connected to the first rotary shaft 73 and the second rotary shaft 74 and may rotate around the first rotary shaft 73; a second arm 76 which is connected to the second rotary shaft 74, supports the plate member 80, and may rotate around the second rotary shaft 74 in a predetermined range; and a sensor 91 configured to detect rotation of the first arm 75 which is rotated by contact between the plate member 80 and the recording medium 5.SELECTED DRAWING: Figure 6 【課題】より確実に記録媒体と板部材との接触を検出することができるプリンタを提供すること。【解決手段】プリンタ１０は、テーブル３５に載置された記録媒体５と板部材８０との接触を検出する検出機構７０を備え、検出機構７０は、ベース部材１３に接続された第１回動軸７３と、第１回動軸７３に対して副走査方向Ｘに偏倚して配置された第２回動軸７４と、第１回動軸７３および第２回動軸７４に接続され、かつ、第１回動軸７３周りに回動可能な第１アーム７５と、第２回動軸７４に接続され、かつ、板部材８０を支持し、かつ、所定の範囲内で第２回動軸７４周りに回動可能な第２アーム７６と、板部材８０と記録媒体５との接触により回動する第１アーム７５の回動を検出するセンサ９１と、を備えている。【選択図】図６
