摘要： A noise masking system in an image forming apparatus such as a laser beam printer or a copying machine having a drive mechanism acting as a noise generation source during operation, the noise masking system comprising a masking sound generator for generating a sound to mask the noise and masking sound control means which controls the masking sound generator to generate a masking sound of a frequency range including a main-component frequency of the noise. The masking sound thus generated is of a frequency range from a lower-limit frequency to an upper-limit frequency in a critical band of the main-component frequency of the noise. The noise masking system masks noise to eliminate a psychological unpleasant feeling caused by frequency fluctuation. It is small-sized and inexpensive.

摘要： An impact dot printer designed to reduce noise, including a first cover, a second cover, and an overlap portion therebetween. The first cover is located above a print section, and may include sound wave reflecting plates, sheet guide plates, and a sound absorbing member, each reflecting plate, each sheet guide plate, and the sound absorbing member being arranged close to the print section. The second cover is rotatable relative to the first cover and forms a printed sheet discharge path together with the first cover. The second cover also has sound wave reflecting plates and sheet guide plates. Each sheet guide plate is designed to be projected farther from the associated cover than the corresponding reflecting plate on said cover. The distance between adjacent sheet guide plates is made smaller than the width of the smallest sheet to be used in the printer. The overlap portion between the first and second covers is arranged so that essentially no opening is provided between the first and second covers when viewed from the top or side.

摘要： A striker bar assembly includes a striker bar body having a recess at each of its opposite ends opening through top, bottom and end wall surfaces. The striker bar body has a flat impact surface perpendicular to the top and bottom surfaces. Generally T-shaped end members have legs for disposition in the striker body recesses. The wall surfaces of the striker body and legs of the members are spaced to provide a gap into which dampening material is provided. The gaps at each end of the striker bar assembly are of identical width in a front-to-back direction.

摘要： A serial impact printer including a novel hammer mechanism for applying a printing force against a character element to drive it in sequence against a marking medium, a mark receiving support, such as a sheet of paper, and the print line on a platen. The hammer mechanism delivers its impact force against a character element along a line forming an angle with a line normal to the surface of the platen at the point of contact of the character element with the platen. This arrangement enhances the ink release of single strike ribbons and multi-part carbon forms. By urging the hammer mechanism against the character element for an extended dwell time of at least 1 millisecond, which is substantially greater than that in conventional printers, the ink release of multi-strike ribbons, fabric ribbons and correctable ribbonsd may also be enhanced. By incorporating both the oblique impact and the extended dwell, the ink release characteristics of all conventional ribbons and multi-part forms will be enhanced.
摘要翻译：一种串行冲击打印机，包括一种新颖的锤击机构，用于将印刷力施加到字符元件上以依次驱动打标介质，标记接收支撑件（例如一张纸）以及压板上的打印线。敲击机构在字符元件与压盘的接触点处沿着与垂直于压板的表面的线形成一定角度的线将其冲击力传递给字符元件。这种布置增强了单打丝带和多部分碳形式的油墨释放。通过将锤击机构推压至少1毫秒的延长停留时间，比现有的打印机要大得多，打印带，织带和可校正色带的墨水释放也可以得到提高。通过结合倾斜冲击和延伸停留，将增强所有常规带和多部分形式的油墨释放特性。
