摘要： A printing device comprises a rotary type wheel provided on its outer surface with a plurality of types disposed at equal angular intervals and in at least one column, a printing hammer head disposed confronting said type wheel and undergoing displacement, in printing operation, to strike a desired type selectively onto a sheet of paper thereby to carry out printing, means for urging the hammer head to move in the direction of carrying out printing action, a mechanism for locking the hammer head in a non-printing position, and a mechanism for releasing the hammer head from its locked state by means of the locking mechanism. The locking mechanism comprises a locking member for locking the hammer head and a first spring for urging the locking member so as to make locking operation. The releasing mechanism comprises a single electromagnet, a second spring facing the electromagnet in spaced-apart relation which is caused to displace when the electromagnet is operated, a locking member displacing together with the second spring, an unlocking cam rotating correspondingly with the rotation of the type wheel and engaging the engaging catch displaced to further move the engaging catch thereby to release the locked state of the hammer head locked by the locking member.

摘要： An apparatus for producing a reset pulse for performing the printing operation of an impact printer. A cam is secured to a shaft of a type drum. The cam has a rising portion, lowering portion, and escape portion. A cam follower is mounted on a lever to engage with the cam. The cam follower has a large diameter portion and a small diameter portion, and a reset switch is provided to be operated by the lever to produce a reset pulse when the lever is rocked by the engagement of the cam follower with the lowering portion of the cam.

摘要： A printer of the needle or hammer impact type prints by release of spring-stored energy, driving the needle or hammer against a platen or character ring. A rotating cam restores the printing member to a locked standby condition after impact, and an electromagnet attracts a moveable core to allow release of the printing member at selected times for printing. The gap between the moveable and fixed cores of the electromagnet is periodically closed mechanically and electrical energization of the electromagnet only maintains the attracted state of the fixed and moveable cores.

摘要： A printer device having a hammer mechanism for printingly impacting a type drum by means of hammer springs. Hammers are rotatably controlled to retracted positions where the hammers are not brought into contact with a reset cam in each printing cycle, so that unnecessary contact between the hammers and the reset cam can be eliminated, frictional loss and noise can be reduced. The hammers are temporarily reset to first retracted positions upon completion of printing, and thereafter, turned to the aforesaid second retracted positions.The release of locking of the hammers is effected by feeding a printing command to electromagnetic means, whereby an armature of the electromagnetic means moves hammer holding members to thereby release locking of the hammers.A predetermined pre-stroke is secured between the hammer holding members and the armature at the time of non-excitation of the electromagnetic means, whereby kinetic energy is accumulated while the armature moves within the aforesaid pre-stroke due to the excitation of the electromagnetic means, so that the hammer holding members can be reliably transferred.
摘要翻译：一种具有锤击机构的打印机装置，用于通过锤簧弹性地冲击型鼓。锤子可旋转地控制到缩回位置，在每个打印循环中锤子不与复位凸轮接触，从而可以消除锤和复位凸轮之间的不必要的接触，可以降低摩擦损失和噪音。在完成打印时，锤被暂时复位到第一缩回位置，然后转到上述第二缩回位置。通过向电磁装置馈送打印命令来实现锤的释放，由此电磁装置的电枢移动锤保持构件，从而释放锤的锁定。在电磁装置的非励磁时，在锤保持构件和电枢之间确保预定的行程，由此由于电磁装置的激励，电枢在前述行程中移动时动能被累积，使得锤保持构件能够可靠地传递。
