    • A paper feeding device which extracts from a cassette accommodating a stack of sheets such sheets one at a time and feeds them to the next step, namely an image forming part, comprises an attracting member capable of being moved between an attracting position at which the attracting member attracts a sheet from within the cassette and a feeding position which lies above the attracting position, a pressing roller capable of being moved between a position of retraction and the feeding position, and a rotary roller capable of cooperating with the pressing roller in nipping the sheet at the feeding position. The pressing roller moves to the feeding position after the elapse of a prescribed time following the completion of the motion of the sheet by the attracting member to the feeding position. The rotary roller is rotatably set in place at the feeding position. The rotary roller may be attached to the attracting member in such a manner as to be moved vertically in both directions in conjunction with the attracting member. When the leading end of the sheet being conveyed by the attracting member from the attracting position to the feeding position comes into contact with the pressing roller held at the position of retraction, the pressing roller acts upon the sheet in the direction of returning the sheet to the cassette.
    • 一种供纸装置,其从一个容纳一叠纸张的纸盒一次提取并将其供给到下一步骤,即图像形成部分,其包括吸引构件,该吸引构件能够在吸引位置之间移动, 构件从盒内吸引片材,位于吸引位置上方的供给位置,能够在缩回位置与供给位置之间移动的加压辊和能够与加压辊配合的旋转辊, 在进纸位置。 在通过吸引构件将片材的运动完成到规定时间之后,按压辊移动到进给位置到进给位置。 旋转辊可旋转地设置在进给位置的适当位置。 旋转辊可以以与吸引构件一起在两个方向上垂直移动的方式附接到吸引构件。 当将吸引构件从吸引位置输送到供给位置的片材的前端与保持在缩回位置的按压辊接触时,按压辊将纸张返回到纸张的方向 盒式磁带。

    • A multihead thermal printer comprises a plurality of thermal heads arranged around a platen roller. An ink film associated with each thermal head includes an end mark leaving a length to an end of the ink film at least equal to that of one sheet of recording paper. A device for detecting the end mark is disposed adjacent to each thermal head. When the detecting device detects the end mark, the printer completes the printing of a sheet of recording paper in the process of printing, but stops the feed of a succeeding sheet.
    • 多头热敏打印机包括围绕压辊设置的多个热敏头。 与每个热敏头相关联的墨膜包括至少与一张记录纸相同的墨迹的一端的长度的端标。 用于检测结束标记的装置设置在每个热敏头附近。 当检测装置检测到结束标记时,打印机在打印过程中完成打印一张记录纸,但停止进纸。

    • A thermal transfer recording technique for printing a multiple tone image by applying energy to a recording head for a period of time corresponding to digital tone data which represents the levels of tones as binary digits.In this technique, a least significant digit of the digital tone data is output as a first signal and second signals are output repeatedly the number of times being equal to the digital tone data of binary form except the least significant digit data. The recording head is driven in response to the first and second signals so as to electrify the recording head for the unit time according to the first signal and for a period of twice as long as the unit time according to the second signal.
    • 一种热转印记录技术,用于通过对记录头施加能量来对应于表示作为二进制数字的音调电平的数字乐音数据的时间段来打印多音色图像。 在该技术中,数字乐音数据的最低有效位被输出为第一信号,并且第二信号被重复地输出等于除了最低有效位数据之外的二进制形式的数字乐音数据的次数。 响应于第一和第二信号驱动记录头,以便根据第一信号使单位时间的记录头通电,并且根据第二信号使单位时间的两倍的时间段通电。
