摘要： A printer capable of completely erasing printed characters while reducing noise which may be generated during the erasure. After an erase key is manipulated and the holder member is moved to its erase position, a motor is energized and driven at a motor current level of I1 and I2 from a time t0 when the erasing operation starts. A print hammer strikes onto a printing paper through a type and a correction ribbon at a hammer speed of V1. Thereafter, motor current level of I3 is applied to the motor, so that the print hammer presses the printing paper at a contacting pressure of P1. In the subsequent erasure operation, the motor current level of I11 and I12, which are smaller than I1 and I2 in the first erasure are applied to the motor. Thus, the hammer speed when striking onto the printing paper by the hammer is lower than V1. Accordingly, contacting pressure of the print hammer onto the printing paper becomes P11, which is smaller than P1 of the first erasure.
摘要翻译： 一种打印机，能够在减少擦除期间可能产生的噪音的同时完全擦除打印字符。 在擦除键被操作并且保持器构件移动到其擦除位置之后，当擦除操作开始时，从时间t0开始以电动机电流I1和I2的电动机来驱动电动机。 印刷锤以V1的锤击速度通过类型和校正带撞击打印纸。 此后，I3的电动机电流水平被施加到电动机，使得打印锤在P1的接触压力下按压打印纸。 在随后的擦除操作中，将第一擦除中小于I1和I2的I11和I12的电动机电流电平施加到电动机。 因此，用锤击打印纸时的锤击速度低于V1。 因此，打印锤与打印纸的接触压力变为比第一擦除的P1小的P11。

摘要： A type-wheel cassette accommodating a type wheel is mounted on a carriage movable along a printing line on a platen. On the carriage is mounted a holder, on which a printing hammer and a type selection mechanism are mounted. The holder has a pair of first urging pieces extending toward the type-wheel cassette. An ink ribbon guide member intervening between the type-wheel cassette and platen has a pair of second urging pieces extending toward the type-wheel cassette. The first and second urging pieces are in contact with the opposite sides of the type-wheel cassette mounted on the carriage in the neighborhood of the printing position. The second urging pieces urge the type-wheel cassette toward the first urging pieces with the elastic spring force of the ink ribbon guide member, whereby the type-wheel cassette is positioned.

摘要： A printer is provided with a platen having a sloping plane platen surface, a medium guide path for smoothly guiding paper along the plane including the platen surface, a transparent open/close paper guide positioned above the medium guide path, and two pairs of drive rollers and driven rollers arranged along the platen, with one pair of drive roller and driven roller being disposed in an upstream direction and the other pair of drive roller and driven roller being disposed in a downstream direction with respect to the platen and the paper print movement. The printer is further provided with a ribbon cassette which makes it possible to position a linear portion of an ink ribbon in parallel to the platen surface, a mechanism for switching the linear portion of the ink ribbon between a printable position and a nonprintable position, and a mechanism for attaching a ribbon cassette to a carriage while moving it in a downwardly forward direction.

摘要： In an automatic paper feed device having a platen and a paper bail arranged to be brought into and out of contact with the platen, the paper bail is further constituted to be brought into contact during a paper is fed in an predetermined amount, and to be brought out of contact during the paper is further fed. The shift operation of the paper bail is controlled by a release mechanism including a driven gear arranged to be rotated with the platen and an intermittent gear arranged to be brought engagement in a predetermined range of angle.Thus, it is possible to design the release mechanism freely since the paper is preliminarily fed without shifting the paper bail.

摘要： A thin key switch device engagement portions formed in a base plate at a reduced processing quantity as compared with a conventional key switch device by effectively utilizing the thickness of the base plate. The key switch device increases the keystroke quantity while reducing the height of the key top arranged in the key switch device, thereby realizing a low profile key switch device.
