摘要： When performing printing by the ink jet head 13, the control unit 78 controls the step motor 75 to rotate counterclockwise by the first number of steps corresponding to the paper feeding quantity of one-line and, after the paper feeding of one-line, to rotate clockwise by the second number of steps smaller than the first number of steps to thereby rotate the paper supply roller 70 clockwise through the middle gear 74 and the driven gear 73, during which the back-tension generated in the paper sheet S is removed. Accordingly, a constant paper feeding quantity can be maintained without regard to the back-tension, providing a stable paper feeding accuracy. Since the back-tension has been removed from the paper sheet S whenever characters and the like are printed on the paper sheet S, in combination of the stable paper feeding accuracy, high printing quality can be obtained without the occurrence of white lines in the printed characters.
摘要翻译：当通过喷墨头13执行打印时，控制单元78控制步进电动机75逆时针旋转与一行的送纸量相对应的第一数量的步骤，并且在单行纸送纸到顺时针旋转小于第一步数的第二步数，从而使供纸辊70顺时针旋转通过中间齿轮74和从动齿轮73，在此期间纸张S中产生的反向张力被去除。因此，可以保持恒定的送纸量，而不考虑背张力，提供稳定的给纸精度。由于只要将文字等印刷在纸张S上，由于纸张S的背张力已经被除去，结合稳定的送纸精度，可以获得高印刷质量而不会在印刷品中出现白线人物。

摘要： The sheet feeder of a recorder includes a sheet support, a shaft extending over the support, a feed roller rotatable on the axis of the shaft, and collars mounted rotatably around the shaft. Disks may be formed on the shaft. Each of the collars is supported rotatably on one of the disks. The inner periphery of at least one of the collars in the widthwise middle area of the support is spaced from the periphery of the associated disk. Even if the support is curved in such a manner that it is convex toward the roller, the distance between the shaft axis and the point or line where the at least one of the collars is in compressive contact with the top one of the sheets stacked on the support is shorter than the distances between the axis and the points or lines where the collars near the lateral ends of the support are in compressive contact with the top sheet. All of the collars can keep the roller and the sheet spaced at a predetermined distance from each other. Consequently, the sheets can be fed properly.

摘要： A print head for dot printers comprising a plurality of actuators each including an armature supported on a holder through a torsion spring and having at its end a printing wire. The torsion spring is inserted in and bonded to the inner wall of through-holes of the bifurcated end portion of one of the armature and holder and to the inner wall of through-hole of the other of them, and has larger diameter portions fitted in the through-holes and smaller diameter portions interposed between the larger diameter portions. The smaller diameter portions of the torsion spring are formed in the concave section to avoid the concentration of torsional stress in the stepped boundary portions. Further, the opposite end portion of the other of said holder and armature made larger in thickness than the axial length of the torsion spring from the reason in strength, is forced at both end openings of the through hole with bevelling or facing portions, whereby the armature can be swung with uniform spring force of the torsion spring without being adversely affected by solder material leaked out.

摘要： In a printer of the type in which printing is carried out on a recording medium with a print element through an ink ribbon interposed between the print element and a sheet or paper, a ribbon cassette accommodating therein the ink ribbon has a ribbon stopper removably provided for limiting the movement of the ink ribbon within the ribbon cassette. A switch is provided for detecting the presence of the ribbon stopper in the ribbon cassette when the ribbon cassette is mounted on the printer. If the ribbon stopper is detected by the switch, then a ribbon feed motor is not energized so that the ink ribbon is not withdrawn from the ribbon cassette. Thus, the ink ribbon will not be cut off, which may otherwise be caused if the ribbon is forcibly withdrawn without removing the ribbon stopper.
摘要翻译：在打印机中，通过墨带插入打印元件和纸张或纸之间进行打印的打印机中，在其中容纳墨带的色带盒具有可拆卸地设置的色带挡块限制色带在色带盒中的移动。当色带盒安装在打印机上时，提供一个开关，用于检测色带盒中色带挡板的存在。如果开关检测到色带挡板，则色带供纸电机未通电，因此墨带未从色带盒中取出。因此，墨带不会被切断，如果在不移除色带挡块的情况下强制拉出色带，则可能会导致墨带。

摘要： A print head for impact type dot matrix printer having means for air-cooling the interior of the print head elevated in temperature due to the generation of heat of solenoid coils, the air cooling means is constituted in such a manner that the outer face of the print head along the direction of movement thereof is formed so as to cause the faster flow of air along said outer face when the print head is moved, and said outer face is provided with ventilating hole means which communicates the interior of the print head and the outside. When the print head is moved, it causes the faster flow along said outer face to thereby draw the air from the interior of the print head through the ventilating hole means due to the difference in pressure.

摘要： In a printer of which the installation area is significantly reduced, a paper roller, a pressure roller, an eject roller, and a spur roller carry printing paper at an angle of T to a horizontal plane. A stacker for storing the printed paper horizontally therein includes a fixed stacker base formed by part of a housing bottom wall and an auxiliary stacker that can be pushed in and pulled out from under the stacker base. This design shortens a horizontal distance between the paper feed roller and the eject roller, forms the stacker base under a printing mechanism sufficiently long, and shortens the auxiliary stacker in the stacker. Consequently, the total length of the printer with the auxiliary stacker fully extended can be reduced, and the entire auxiliary stacker can be accommodated under the printer.

摘要： An ink jet printer comprises an ink jet print head with detachable ink cartridges, a carriage holding the print head, a controller for controlling their actions, and an outer case having an opening formed for detachment of the ink cartridge and mounting of a new ink cartridge. To the outer case, a manual operation key and an opening/closing cover for closing the opening are attached. The opening and closing of the opening/closing cover are detected by a sensor. The manual operation key has two action modes. When the opening/closing cover is opened, the controller switches the action modes from a sheet feed mode to a mode for moving the carriage to a region opposed to the opening for detachment of the ink cartridge and mounting of a new ink cartridge. The number of operation keys is decreased, and key operation becomes easy. A display of an action is made on the outer case and the opening/closing cover so that each action can be known whether the opening/closing cover is open or closed.
