摘要： A clamping device for a printer has a plurality of sideways-slippage preventing rollers housed in a roller housing which is fixed to a rear face of a wall of a ribbon shield. These preventing rollers prevent the printing paper from slipping sideways during a printing operation. A plurality of pressing plates are fixed on a hammer cover and biased towards the preventing roller by springs. A printing paper travels between the preventing rollers and the pressing plates, and the preventing rollers are oriented to rotate in the direction in which the printing paper travels. Since the preventing rollers prevent the printing paper from slipping sideways during printing, the printing lines are aligned properly. The preventing rollers also exert a minimum forward clamping force on the printing paper, which thus prevents the paper from tearing.
摘要翻译：用于打印机的夹紧装置具有容纳在辊壳体中的多个侧向防滑滚子，该辊壳体固定到带状屏蔽件的壁的后表面。这些防止辊在打印操作期间防止打印纸侧向滑动。多个按压板固定在锤子盖上，并通过弹簧朝防止辊偏压。打印纸在预防辊和按压板之间行进，并且防止辊被定向成沿着打印纸行进的方向旋转。由于防止辊在打印期间防止打印纸侧面滑动，所以打印线对准。预防辊也在打印纸上施加最小的向前夹紧力，从而防止纸张撕裂。

摘要： In a control device for an impact printer for performing a printing operation at a first printing speed, a temperature sensing element, provided such that the temperature of an electromagnet unit can be directly or indirectly detected, is operated at a first temperature and restored at a second temperature lower than the first temperature. A controller changes the printing speed to a second printing speed lower than the first printing speed when the temperature sensing element is operated, returns the printing speed to the first printing speed when the element is restored, and changes the operating speed to a third printing speed lower than the second printing speed when the element is operated for a predetermined period of time, whereby the printer is made high in reliability.

摘要： A thermal printer wherein a sheet of recording paper is interposed between two drums provided on axially opposite sides of a shaft of a platen roll facing a line-type thermal head and an endless belt mounted on outer peripheries of the drum. One way clutches provided on a shaft of the drum will cause the paper to rotate together with the drums during recording and the recording paper is driven by the endless belt during paper feed and delivery operations to slide relative to the drums. The sheet of paper is fed to a lower portion of an open portion of the drums and is removed from an upper portion of the open portion of the drums so that the feed and delivery of the sheet of paper can be effected upon rotation of the drums in one direction, and the printing operation is started after a detection of a trailing end of the sheet of paper so that the printing operation can be reformed regardless of the length of the sheet of paper immediately after the feed of the sheet of paper.

摘要： A device for cleaning a rotary type-carrier, in which a brush which contacts the type-carrier continuously to clean it during normal operation may be moved so that its rotary center is positioned more closely to the type-carrier. As a result, as the brush wears out, it may maintain contact with the type-carrier, obviating the need for frequent replacement.

摘要： A line printer of the type using a 384-character type carrier receives a 240-character type data array from a computer designed for a 240-character line printer and converts the 240-character array into a 384-character data array with no partial character sets. The converted 384-character data array corresponds exactly to the characters on the type carrier. The type carrier includes a number of dummy characters in each character set if the type carrier employs other than 48-character sets.
摘要翻译：使用384字符型载体的行式打印机从为240字符行打印机设计的计算机接收240个字符的数据阵列，并将240个字符的数组转换为384个字符的数据阵列，不带部分字符套。转换的384字符数据数组完全对应于类型载体上的字符。如果类型载体使用除48个字符的集合之外，则类型载体包括每个字符集中的多个虚拟字符。

摘要： A paper tension adjusting device in which one of the tractors with feeding pins changing feeding apertures in the paper is movable widthwise to adjust widthwise paper tension. The desired tension is determined from paper thickness which is in turn determined from the hammer flight time. Lengthwise tension is adjusted by adjusting paper clampers separated from the tractors. The tension is both widthwise and lengthwise directions is determined by optically sensing the positions of the feeding pin with respect to the aperture in which that pin is engaged.

摘要： An apparatus for detecting a feeding of paper has a reflector which is mounted on a bottom of a switch lever. The switch lever, in turn, is slidably mounted on black paper retainer plate which has poor reflecting properties, and a light emitting element emits light which is reflected by the paper towards a light receiving element. When paper which has good reflecting properties is being fed, the reflector is slid so that it is no longer located opposite the light emitting element, and any light passing through holes in the paper is thus poorly reflected by the black paper retainer plate, thereby enabling the light receiving element to readily detect the presence or absence of a hole in the paper. However, when the paper being fed has poor reflecting properties, the reflector is slid so that it is located opposite the light emitting element, and any light passing through one of the holes in the paper is strongly reflected by the reflector. Therefore, again, the light receiving element can readily detect the presence or absence of the holes.
