PRINTING DEVICE

To provide a printing device that can easily perform operation for bringing the device into a printable state.SOLUTION: The printing device comprises: a head holder 3 for holding a thermal head; a platen holder 4 that rotatably supports a platen roller 4R with a support shaft 40 as a center and can move in a longitudinal direction; an engagement member 5 that can be engaged with and disengaged from the head holder 3; and a moving mechanism 6 that moves the platen holder 4 and the engagement member 5, which moves the platen holder 4 across a retracting position at which the platen roller 4R is separated from the head holder 3 and a pressing position at which a printing medium is pressed against the thermal head by the platen roller 4R, and moves the engagement member 5 from a releasing position at which the member is separated from the head holder 3 and is not engaged with the head holder 3 to an engaging position at which the member is made to approach the head holder 3 and engaged with the head holder 3, in response to movement of the platen holder 4 from the retracting position to the pressing position.SELECTED DRAWING: Figure 3 【課題】印刷可能な状態とするための操作を簡易に行うことができる印刷装置を提供する。【解決手段】印刷装置は、サーマルヘッドを支持するヘッドホルダ３、支持軸４０を中心としてプラテンローラ４Ｒを回転可能に支持し、且つ、前後方向に移動可能なプラテンホルダ４、ヘッドホルダ３に係脱可能な係合部材５、プラテンホルダ４及び係合部材５を移動させる移動機構６であって、プラテンホルダ４を、プラテンローラ４Ｒがヘッドホルダ３から離隔した退避位置と、プラテンローラ４Ｒにより印刷媒体をサーマルヘッドに押し付ける押圧位置との間に亙って移動させ、且つ、プラテンホルダ４が退避位置から押圧位置に移動したことに応じ、係合部材５を、ヘッドホルダ３から離隔してヘッドホルダ３に係合しない解除位置から、ヘッドホルダ３に近接してヘッドホルダ３に係合した係合位置に移動させる移動機構６を備えている。【選択図】図３
