摘要： An improved wire dot print head for increased integrated density is provided. The wire dot print head includes a frame. A plurality of drive coils are mounted within the frame. A lever for driving print wires has a print wire mounted at one end and its other end formed as a hook to act as a rotation support member. When an excitement current flows through the coil, the lever is caused to move so that the print wires rotate about the rotation support member causing the print wires to strike a platen. The wires guided by guide holes which form a circular array at one armature end, and a row or rows at the printing end.

摘要： Disclosed is an impact dot head and an impact dot printer provided as not causing wire breakage by supporting a wire performing a printing operation so as to be resiliently oscillatable in a printing digit direction even if the impact dot head starts printing from a position outside a printing sheet due to erroneous setting of a printing area and therefore passes an end of the printing sheet while performing the printing operation.

摘要： A serial printer having a dot type printing head for printing on a paper. The printer includes 2N columns of dot forming elements where N is a positive integer equal to 2 or more and a carriage supported on the printer for reciprocal movement across the paper in a carriage direction. The columns of dot forming elements are supported on the carriage for selectively printing dots on a paper. Each column of the dot forming elements is spaced a predetermined distance from adjacent columns of the dot forming elements in the carriage direction. Each dot forming element column includes a plurality of dot forming elements arranged in a line and spaced apart from one another in the column direction by a dot pitch substantially equal to N. A drive system selectively drives selected dot forming elements in each column of dot forming elements by one of an even number timing and an odd number timing. Each column of dot forming elements driven by an even number timing is shifted in the column direction by one dot with respect to each other column of dot forming elements driven by an even number timing. Each column of dot forming elements driven by an odd number timing is shifted in a column direction by one dot with respect to each other column of dot forming elements driven by an odd number timing. Each column of dot forming elements driven by an even number timing is shifted in the column direction by less than about 1/3 dot pitch with respect to at least one column of dot forming elements driven by an even number timing.

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 serial printer for printing on a recording medium which includes a platen, a carriage and a recording medium discharge section. The platen serves as a recording medium insert member and is rotated by a motor. A carriage shuttles in parallel with the platen and includes a recording head and a paper holder attached thereto. The sheet discharge section is arranged on a downstream side of the carriage and is provided for guiding the recording medium to a sheet discharge outlet. The printer further includes a carriage controller for moving the carriage towards the center of the recording medium and stopping the carriage proximate the center of the recording medium, while decelerating the carriage before the center of the recording medium, when the recording medium is forwarded for printing until the recording medium reaches a sheet discharge section from a predetermined position on the downstream side of the paper holder. A forward controller is provided for starting a recording medium forward operation for a single line of the recording medium in sync with the deceleration of the carriage. The carriage controller further moves the carriage proximate the center of the recording medium upon turning on the printer. The carriage controller also moves the carriage proximate the center of the recording medium when a print operation on the recording medium has ended.

摘要： An impact dot print head for printing without impact noise when returning to the non-printed position includes a base. An arm is mounted for movement between a non-print position and a print position. A print wire is mounted on the arm. A first device selectively drives the arm towards the print position by bias or magnetic force. A second device returns the arm to the non-print position and maintains the arm at that position without causing the arm to impact any member of the print head when returning to the print position. The second device uses balanced magnetic attraction or repulsion and/or bias forces to hold the arm out of contact with other parts of the printer other than at its point of mounting when at the non-print position.
