摘要： A print-head assembly for a printing apparatus includes: a carriage with a frame configured to be supported on a gantry for movement in a travel direction over a print surface; a print-head unit having one or more print heads mounted on the carriage; and an impact damping device mounted on an end region of the carriage in the travel direction, wherein an impact member of the damping device presents a contact surface in the travel direction. The impact member is mounted to the carriage frame for resilient movement over a buffer distance substantially parallel to the travel direction between a first extended position and a second retracted position for absorbing or damping an impact during movement of the carriage in the travel direction.

摘要： A frame structure of a printing apparatus is provided with a main frame having a developer unit and a paper supply and output unit, a subframe installed in the main frame, having a printing unit, and a damping member installed between the main frame and the subframe, for absorbing vibration which would otherwise be transferred from the main frame to the subframe. Thus, the damping member can prevent the vibration generated by the developer unit or the paper supply and output unit from being transferred to the printing unit.

摘要： A base for operative association with an operating mechanism sensitive to horizontal vibration, such as an ink jet printer, supports a horizontal document feeder plate and associated drive operative to advance documents in sequential fashion from a stack toward the operating mechanism. A drive linkage interconnects a rotatable drive shaft to the feeder plate to effect horizontal reciprocating movement thereof. A counterweight is associated with the drive so as to substantially offset or nullify horizontal inertia forces imparted to the base by the feeder plate whereby to minimize horizontal vibration of the base. In an embodiment utilized for intermittent feeding of documents to the operating mechanism, a balance arm and associated counterweight cooperate with the feeder plate to offset horizontal inertia forces imparted to the base, and also minimize start-up torque required to initiate reciprocating movement of the feeder plate after stoppage.

摘要： A print head for a dot printer of the present invention includes a plurality of armatures which support a print wire on one end. A back stopper is provided on the rear side of the armatures to stop the armature as the print wire retreats after a print strike. The back stopper is provided with openings so that when an armature strikes the back stopper, upon withdrawal from the print strike, the noise emanated from the back stopper is reduced. A sound dampening piece may be abutted to the rear of the back stopper to further reduce the noise.
摘要翻译：本发明的点式打印机的打印头包括在一端支撑印刷线的多个电枢。在打印打印后打印丝退后，在电枢的后侧设置有后挡块，以阻止电枢。后挡块设置有开口，使得当电枢撞击后挡块时，当从打印打印中退出时，从后挡块发出的噪音减小。防音片可以抵靠后挡块的后部，以进一步降低噪音。

摘要： An adaptive paper slot device providing adjustment for the location of paper slot feeds to and from a printer located within an acoustic silencer enclosure to permit using one enclosure with a number of printers having different paper feed locations. The adapter device is mounted on one wall of the silencer enclosure and has a number of adjustable horizontal bars which cover the end of the enclosure with horizontal slots between the bars. The bars can be relocated to move the slots for paper feed to any desired vertical location. The inner surface of the bars is covered with sound absorbing material to maintain the integrity of the acoustic silencer enclosure excepting for the proper feed slots themselves.
