    摘要： The objective of this invention is to provide fluorescent compounds comprising a naphthalene skeleton, an electron donating group substituted at the 2- or 1-position of the naphthalene skeleton, and an electron attractive group substituted at the 6- or 4-position of the skeleton. The fluorescent compound of this invention is capable of emitting visible light having a desired color by choosing an appropriate combination of the electron donating group A, which has an electron-pushing function, and the electron attractive group B, which has an electron-pulling function.

    摘要： Method of feeding a sheet of paper in a small-sized paper having small transport rollers mounted downstream of the print head. The feeding of the sheet is stopped temporarily when the sheet arrives at each of a number of positions located before the discharge rollers during a line feed operation. Under this interrupted condition, the print head is reciprocated once idly in a direction perpendicular to the direction in which the sheet is fed. Therefore, even if the front end portion of the sheet curls to a great extent, the curl is reduced by the idle movement of the head immediately before the front end of the sheet arrives between the discharge rollers. This ensures that the sheet is fed between the discharge rollers even if the diameter of the rollers is small.

    摘要翻译： 在安装在打印头下游的小型输送辊的小型纸中进给纸张的方法。 当在进给操作期间片材到达位于排出辊之前的多个位置的每一个处时，暂时停止片材的进给。 在这种中断状态下，打印头在垂直于纸张进给方向的空白方向一次往复运动。 因此，即使纸张的前端部分在很大程度上卷曲，在纸张的前端在排出辊之前到达之前，头部的怠速运动也减小了卷曲。 这确保了即使辊的直径小，也可以在排出辊之间输送片材。

    摘要： A paper feeding system that eliminates a mechanism for interrupting driving force to picking rollers to lower the cost of the system and to secure the feeding of papers. Corner nails are supported in a manner displacable up and down on the both sides of the front end portion of a paper cassette and the front corner portions of papers stored within the paper cassette can be anchored by the corner nails. A projecting part of the corner nails abuts to a stopper to restrict its upper limit position. When the paper is not fed, the picking rollers are in an up position and are separated from the paper and the corner nails retain the paper at a certain height position engaging with the front corner portion of the paper. When the paper is fed, the picking rollers go down to a down position to press the paper against biasing force of a bias spring and the corner nails are separated from the stopper and contact with the front corner portion of the paper in the down position.

    摘要翻译： 一种送纸系统，其消除了用于中断采摘辊的驱动力以降低系统成本并确保纸张供给的机构。 角钉在纸盒的前端部的两侧能够上下移动的方式被支撑，并且存储在纸盒内的纸张的前角部分可以被角钉固定。 角钉的突出部分与止动器相接以限制其上限位置。 当纸张不进纸时，拾纸辊处于向上位置并与纸分离，角钉将纸保持在与纸的前角部分啮合的一定高度位置。 当送纸时，拾纸辊下降到向下位置，以克服偏压弹簧的偏压力按压纸张，角钉与止动器分离，并与纸张的前角部分处于向下位置。

    摘要： A paper feeder includes a rotatable feed roller and a retard roller biasingly urged toward one another, the feed roller being rotatable in a feed direction for feeding a paper sheet between the feed roller and the retard roller. A pivot arm pivotably supports the retard roller, and a motor mounted on the pivot arm is operable to apply a turning torque to the retard roller in a direction opposite to the direction of feed of the feed roller.

    摘要： A device for changing a passageway for paper includes flaps pivotably provided at branching points of the passageway and operable to change the paper feeding direction. Solenoids mounted with shafts are extended by first springs during non-energizing and retract during energizing, and second springs are provided for imparting biasing forces to follow the displacement of the shafts and to pivotably bias the flaps so that the flaps receive rotational moments of force acting in opposite directions in the energizing and non-energizing states, the rotational moment of force being set so as not to hinder the feed of the paper.
