前記ばねホルダを介して前記コイルばねを上方に押圧した状態で、前記プリンタ本体の所定位置に形成された支持部に支持された取り付け状態と、前記所定位置から取り外されて前記支持部に支持されない取り外し状態とを採りうる着脱自在のプリントヘッドユニットと、を備え、
前記プリントヘッドユニットが前記取り付け状態のとき、前記押圧部材と前記プリントヘッドユニットとが互いに係合して、前記プリントヘッドユニットに対する前記押圧部材の位置決めを行う係合部をそれぞれ有し、
前記押圧部材は、前記プリントヘッドユニットの幅方向に直交する上下方向に傾斜させて前記係合部による前記プリントヘッドユニットとの係合を解除する方向に変位させることにより、前記プリントヘッドユニットを前記取付け状態から前記取り外し状態とする係合解除部を有しているプリントヘッドユニットの支持構造。 A pressing member having a coil spring suspended from the printer body and a spring holder fixed to the lower end of the coil spring.
With the coil spring pressed upward through the spring holder, the printer body is supported by a support portion formed at a predetermined position and is removed from the predetermined position and is not supported by the support portion. Equipped with a removable print head unit that can be removed
When the print head unit is in the mounted state, the pressing member and the print head unit are engaged with each other to have engaging portions for positioning the pressing member with respect to the print head unit.
The pressing member is tilted in a vertical direction orthogonal to the width direction of the print head unit and displaced in a direction in which the engaging portion is disengaged from the print head unit, thereby causing the print head unit to be disengaged. A support structure for a printhead unit having a disengagement portion that changes from the mounted state to the disengaged state.
前記プリントヘッドユニットが有する前記係合部は、前記押圧部材の前記凸部と係合する凹部又は前記押圧部材の前記凹部と係合する凸部であり、
前記係合部は、前記プリントヘッドユニットに対する前記押圧部材の前後方向の位置決めを行う請求項１に記載のプリントヘッドユニットの支持構造。 The engaging portion included in the pressing member is a convex portion or a concave concave portion formed in the spring holder and protruding toward the print head unit.
The engaging portion included in the print head unit is a concave portion that engages with the convex portion of the pressing member or a convex portion that engages with the concave portion of the pressing member.
The support structure for a printhead unit according to claim 1, wherein the engaging portion positions the pressing member in the front-rear direction with respect to the printhead unit.
前記取り付け状態から前記後側の部分が上方に押し上げられた後上がりの傾斜状態では、前記被支持部が前記支持部に支持されない状態となり、
前記係合解除部により前記係合部による係合が解除された状態で、前記プリントヘッドユニットは、前方に引き出す方向に取り外し可能の状態となる請求項１又は２に記載のプリントヘッドユニットの支持構造。 The printhead unit has a supported portion supported from below by the support portion at a rear portion in the front-rear direction orthogonal to the width direction of the printhead unit.
In the tilted state in which the rear portion is pushed upward from the mounted state and then rises, the supported portion is not supported by the support portion.
The support for the printhead unit according to claim 1 or 2, wherein the printhead unit is in a removable state in a direction of being pulled out forward in a state where the engagement by the engagement portion is disengaged by the disengagement portion. structure.
前記プリントヘッドユニットが、前記支点突起を回動中心として前記ばねホルダを、前記傾斜面に接するまで回転させることにより、前記係合部による係合を解除する請求項３に記載のプリントヘッドユニットの支持構造。 The disengagement portion is formed on the spring holder and has an inclined surface that rises backward on the rear portion, and a top surface of the printer body that faces the upper part of the spring holder or the upper part of the spring holder. It has a fulcrum protrusion formed on the surface of the spring, which serves as a fulcrum for rotating the spring holder in contact with the top surface.
The printhead unit according to claim 3, wherein the printhead unit rotates the spring holder around the fulcrum protrusion until it comes into contact with the inclined surface to release the engagement by the engaging portion. Support structure.
