Description
本発明は、排出されたシート状のメディア（以下、「シート」と称する。）を搬送するシート搬送装置およびプリント装置に関する。 The present invention relates to a sheet conveying device and a printing device that convey a discharged sheet-shaped medium (hereinafter, referred to as a “sheet”).
上記目的を達成するために、本発明によるシート搬送装置は、駆動力によって回転してシートを搬送方向に搬送する搬送ローラと、前記搬送ローラのシャフトと同軸に設けられ、前記搬送ローラにより搬送されるシートに接触する検知ローラと、前記検知ローラの回転状態を検知する検知部と、を備え、前記検知部の検知結果に基づいて、シートの搬送を制御するシート搬送装置であって、前記検知ローラは、前記シャフトの回転に連れて回転するとともに前記検知ローラに所定以上の負荷がかかると前記シャフトの回転の伝達が断たれるトルクリミッタを介して前記シャフトに設けられていることを特徴とする。 In order to achieve the above object, a sheet conveying apparatus according to the present invention is provided with a conveying roller that rotates by a driving force and conveys a sheet in a conveying direction, and is provided coaxially with a shaft of the conveying roller, and is conveyed by the conveying roller A sheet conveyance device that includes a detection roller that contacts a sheet to be detected, and a detection unit that detects a rotation state of the detection roller, and controls conveyance of the sheet based on a detection result of the detection unit. The roller is provided on the shaft via a torque limiter that rotates with the rotation of the shaft and that transmits the rotation of the shaft when a predetermined load or more is applied to the detection roller. I do.
