Summary:To provide a support mechanism of a platen roller, which can prevent or suppress strength from deteriorating and enables a size corresponding to an axial direction of the platen roller to reduce.SOLUTION: A support mechanism 30 of a platen roller 81 comprises a shaft member 31 arranged in parallel with the platen roller 81 and engagement members 32 and 33 provided at both end parts of the shaft member 31. The engagement members 32 and 33 can rotate with the shaft member 31 as a center, between an engaging position where the members engage with a platen unit 80 being fitted to a frame 10 to support the platen roller 81 at a predetermined position and a releasing position where the engagement thereof with the platen unit 80 is released, and surfaces 32g and 33g which are orthogonal to each other in an axial C2 direction (a width direction W) of the shaft member 31 of the engagement members 32 and 33 are formed as guide surfaces for regulating a position in the width direction of a sheet 200.SELECTED DRAWING: Figure 4 【課題】プラテンローラの支持機構において、強度の低下を防止又は抑制するとともに、プラテンローラの軸方向に対応したサイズを小さくすることができるものとする。【解決手段】プラテンローラ81の支持機構30は、プラテンローラ81と平行に配置された軸部材31と、軸部材31の両端部に設けられた係合部材32,33と、を有し、係合部材32,33は、フレーム10に装着された状態におけるプラテンユニット80に係合して、プラテンローラ81を所定の位置に支持する係合位置と、プラテンユニット80との係合が解除された解除位置との間で、軸部材31を中心として回転可能であり、かつ、係合部材32,33の軸部材31の軸C2方向(幅方向W)に直交した面32g,33gが、用紙200の幅方向の位置を規制する案内面として形成されている。【選択図】図4
