摘要： PURPOSE:To make it possible to cope with reductions in size and weight and an increase in speed and contrive a longer useful life, by providing a conductive guide member having a groove for slidably guiding a power-feeding member, and sliding the power-feeding member in the groove when moving a movable plate. CONSTITUTION:A power-feeding part 7a is provided at the lower end of a movable plate 2b, and has a guide function as well as conductivity. Slide guide members 9a, 10 have guide grooves 11a, 11b, in which the power-feeding part 7a and a guide part 8 are slidably engaged, respectively. A coil 1b can be energized through the slide guide member 9a and the power-feeding part 7a. With the coil 1b energized, the movable plate 2b is projected in the direction of an arrow A against the elastic force of a spring 12 while the power-feeding part 7a and the guide part 8 are guided along the guide grooves 11a, 11b of the slide guide members 9a, 10, and a hammer part 3a collides against a back part of a type on a type wheel, thereby performing printing. With the coil deenergized, the plate 2b is returned to an initial position by the recoiling strength of the spring 12 while the power-feeding part 7a and the guide part 8 are guided by the guide grooves 11a, 11b.

摘要： PURPOSE:To eliminate the eccentricity of a hammer body and to make it possible to perform smooth driving without backlash, by sequentially mounting a first guide, a magnetic ring, and a second guide to a base part, which is formed as a unitary body, when a plunger type hammer is manufactured. CONSTITUTION:A first guide 2c is coupled into a base 2e, which is molded as a unitary body with a striking part 2a, from the rear of a hammer 2, and pushed until the guide is contacted with a projection 2f at the base 2e. The guide is bonded to the base. Then, a ring 2b and a second guide 2c are coupled and bonded to the base 2e by the same way. Thus the hammer 2 is assembled. The hammer body 2 assembled in this way is aligned with the center A-A' of the ring. Therefore, there is no backlash when a current is conducted through a coil 10 and the hammer is moved back and forth in a stator 11, and scarce abrasion of the guides is produced.
摘要翻译：目的：为了消除锤体的偏心度，并且能够无间隙地进行平滑的驱动，通过依次将第一引导件，磁环和第二引导件安装到形成为整体的基部上，当制造柱塞式锤时。构成：第一引导件2c联接到基座2e中，底座2e从锤2的后部被模制成具有击打部分2a的整体，并被推动直到引导件与基部2e处的突起2f接触。指南与基地结合。然后，环2b和第二引导件2c通过相同的方式联接并结合到基部2e。因此，锤2被组装。以这种方式组装的锤体2与环的中心A-A'对准。因此，当电流通过线圈10传导并且锤子在定子11中来回移动时，没有齿隙，并且导致引导件的磨损不足。

摘要： PURPOSE:To optimize printing conditions (printing pressure) corresponding to the type of printing medium by varying the distance between the hammer tip of a hammer magnet and a platen while the excitation of the magnet is adjusted according to said distance. CONSTITUTION:A type of a type wheel 18 which is guided with a guide shaft 13 and moves horizontally with the turning of a screw 12 is pressed on a printing medium 20 on a platen 11 with a hammer of a hammer magnet 19 to print. In said printer, a type on the type wheel 18 is moved in the directions of the arrows C and D by turning a lever 22 in the direction of the arrow through a guide shaft 13 integral with an eccentric section 13a, a carrier frame 14 and the like and positioned at an appropriate distance with respect to the printing medium 20. At the same time, a selector switch 23 (23a) works to output a signal to control an exciting current of the hammer magnet 19 whereby the printing condition will be optimized.

摘要： PURPOSE:To enable to solve a problem of discrepant printing upon printing on a thick printing medium and improve a printing quality even in a high-speed printing by making a feeding direction of an ink ribbon reverse to a space direction of a carrier. CONSTITUTION:A feeding direction A' of an endless ink ribbon 13 is made reverse to a space direction A of a carrier in a flying space printing type printing mechanism in which printing is effected by a predetermined speed continous space operation of the carrier equipped with a type receiving member having numbers of types 12. As a result, when a hammer 11 finishes printing and begins to retreat and the type 12 biting into a printing medium 4 is going to escape from the medium 4, the type 12 tries to return to a normal condition by moving a moved distance of the hammer 11 in the direction designated by the arrow sign A by the time, however, this movement is decreased by the movement of the ink ribbon 13 moving to the direction designated by the arrow sign A' which is opposing to a direction of movement of a prior art mechanism.
