    Abstract: A printing device employs a printing drum on the peripheral wall of which a plurality of character types are arranged in the axial direction and in the circumferential direction. The axial movement and rotation of the drum are independently controlled by comparing the position of a new character type on the drum to be printed with that of the immediately preceding one of already printed character types thereon at each printing step in response to electric printing information. A hammer is disposed close to the outer periphery of the drum. The hammer advances step by step in printing in the axial direction of the drum independently of the drum to determine the printing position with respect to a record sheet and selectively strikes the opposed surface of the drum through the record sheet. The printing device can thus attain a mechanical driving system for the drum and hammer which has the simplest construction, the least probability of trouble, and a highest possible printing speed with ease.

    Abstract translation: 印刷装置在其周向壁上沿轴向和周向布置多个字符类型的印刷滚筒。 响应于电打印信息，通过在每个打印步骤上比较在打印滚筒上的新字符类型的位置与在其上打印的字符类型之前的其它打印字符类型的位置之间的轴向移动和旋转。 锤子靠近鼓的外周设置。 在独立于滚筒的情况下，锤在滚筒的轴向方向上逐步进行打印以确定相对于记录纸的打印位置，并通过记录纸选择性地撞击滚筒的相对表面。 因此，打印装置可以获得用于鼓和锤的机械驱动系统，其具有最简单的结构，最少的故障概率和最高可能的打印速度。

    Abstract: A shuttle is disclosed which carries as part of its assembly at least a pair of follower blocks for providing the motion required to effect selection on a single element typewriter. The shuttle allows the follower blocks to provide the requisite motion and also allows a non-disengaging drive of the shuttle with the controlling driving shaft.

    Abstract: A power-driven typewriter comprising a shiftable carrier supporting a rotatable and axially movable, flexible type drum having a plurality of type characters therearound. Type keys, when depressed, each condition one each of two groups of actuators and cause operation of a drive member to operate the two conditioned actuators, one of which is effective to rotate the type drum from any position to a new position and the other is effective to raise the type drum to a selected position to thus align a type character corresponding to the key depressed at the printing point. Means are provided to dampen torsional oscillation of the type drum and its drive mechanism prior to printing. Readily interchangeable ink transfer ribbon cassettes for both fabric and for film ribbons are provided. Also, type drums having different type characters or type styles may be readily interchanged.

    Abstract: A novel internal actuator for impacting the print head of a high speed serial printer with a print medium is disclosed. The internal actuator engages the interior of a rotatably and axially positionable print head and causes the latter to impact the print medium. The internal actuator includes a pivotal yoke portion and a neck portion, the latter of which extends into the interior of the print head. The pivotal yoke portion provides a fixed point about which the print head moves while the neck portion provides a firm mounting for both the positioned print head and the positioning shaft structure which is contained therein.

    Abstract: THREE BELT DRIVE ASSEMBLIES COOPERATE TO SELECTIVELY POSITION A CYLINDRICAL CHARACTER FONT CARRIER IN A SERIAL PRINTER ANGULARLY ABOUT ITS AXIS OF ROTATION, LINEARLY ALONG SAID AXIS, AND LINEARLY IN A DIRECTION PERPENDICULAR TO SAID AXIS. THESE MOVEMENTS MAY OCCUR CONCURRENTLY TO MOVE ANY DESIRED CHARACTER ON THE FONT CARRIER INTO PRINTING POSITION.
