摘要： PROBLEM TO BE SOLVED: To improve an identification accuracy of a residual amount of a recording medium. SOLUTION: A paper holder 110 is provided for supporting an outer circumferential surface of the roll-shaped recording medium 102 urged to a lower side in a vertical direction due to its self weight such that a center position of the recording medium 102 moves on a linear locus along with consumption of the recording medium 102. A light reflection type sensor arranged at a predetermined position on a side surface of the paper holder 110 is provided for detecting the displacement amount per unit time at a position opposite to a predetermined position of the recording medium 102 which is rotated by being pulled out from the paper holder 110 along with consumption of the recording medium 102. Based on the displacement amount detected by the light reflection type sensor, a radius of the recording medium 102 at detection by the light reflection type sensor is calculated.

摘要： PROBLEM TO BE SOLVED: To provide a paper feeder which can suppress the generation of irregular prints by mitigating an impact accompanied by the starting of the draw-out of a roll paper.
SOLUTION: The paper feeder is equipped with a roll paper setting section 12 which is opened upward to keep a roll paper 13 thrown in and stored. The roll paper setting section 12 has a first roll paper receiving wall 14 and a second roll paper receiving wall 15 rotatably supporting the roll paper 13 drawn out of the setting section and printed. The first roll paper receiving wall 14 is provided so that a contact force of the roll paper 13 to the roll paper receiving wall 14 accompanied by the draw-out of the roll paper 13 becomes larger than a stopped state. The second roll paper receiving wall 15 is provided so that the contact force of the roll paper 13 to the roll paper receiving wall 15 accompanied by the draw-out of the roll paper 13 becomes smaller than the stopped state. The friction coefficient between the roll paper receiving wall 14 and the roll paper 13 slidingly contacting with the wall is made smaller than the friction coefficient between the roll paper receiving wall 15 and the roll paper 13 slidingly contacting with the wall.

摘要翻译：要解决的问题：提供一种能够通过减轻伴随卷纸的拉出开始的冲击来抑制不规则印刷品的产生的供纸装置。
解决方案：供纸装置配备有向上打开以保持卷纸13投入并存储的卷纸设定部12。卷纸设置部分12具有第一卷纸接收壁14和第二卷纸接收壁15，第二卷纸接收壁15可旋转地支撑从设置部分拉出的卷纸13并打印。第一卷纸接收壁14设置成使得卷纸13与卷纸接收壁14的接触力伴随着卷纸13的拉出而变得大于停止状态。第二卷纸接收壁15被设置成使得卷纸13与卷纸接收壁15的接触力伴随着卷纸13的拉出而变得小于停止状态。使卷纸接收壁14与与壁滑动接触的卷纸13之间的摩擦系数小于卷纸接受壁15和与壁滑动接触的卷纸13之间的摩擦系数。版权所有（C）2008，JPO＆INPIT
