    • The printwheel (20) includes a hub portion and a plurality of radially extending, deflectable petals (21) projecting therefrom. The petals include a pad or tip 24 thereon with print forming indicia (52) on one side (24a) thereof and a striking surface on the opposite side (24b) thereof adapted to be struck by a print hammer (30) to move the indicia (52) against a print receiving medium. The striking surface on side (24b) comprises first and second, oppositely inclined, radially spaced apart surfaces (25), (26), which are in superimposed overlapping relation in plan. Surfaces (25) and (26) are disposed to be engaged by complementary inclined surfaces (32), (33) on the print hammer (30) whereby angular misalignment between the hammer (30) and the petal (21) may be compensated for by lateral deflection of the petal (21) to effect a detenting between the complementary inclined surfaces (25), (26) of the petal (21) and the print hammer (30).
    • 所述印刷头(20)包括毂部分和从其突出的多个径向延伸的可偏转瓣片(21)。 花瓣包括在其上的垫或尖端24,在其一侧(24a)上具有印刷形成标记(52),并且在其相反侧(24b)上具有打击表面,适于被打印锤(30)击打以移动标记 (52)抵靠打印接收介质。 侧面(24b)上的撞击表面包括第一和第二相对倾斜的径向隔开的表面(25),(26),它们在平面上以叠加的重叠关系。 表面(25)和(26)设置成与打印锤(30)上的互补的倾斜表面(32),(33)接合,由此可以补偿锤(30)和花瓣(21)之间的角度不对齐 通过花瓣(21)的横向偏转来实现花瓣(21)的互补倾斜表面(25),(26)和打印锤(30)之间的锁定。

    • A printing recorder has an endorser hammer joint (32) which enables rockable and lateral movement of a print hammer (20) in order to provide parallel alignment of the striking surface (22) of the print hammer (20) and a platen (24) when the print hammer (20) is engaged theragainst. The endorser hammer joint (32) includes a socket (34) having a bottom surface (35), a plunger (36) for engaging the socket (34), the plunger (36) having an end (37) contacting the bottom surface (35), and positioning means (38) for resiliently positioning the plunger end (37) in a home position on the bottom surface (35) and also for permitting rockable and lateral movement of the bottom surface (35) with respect to the plunger (36).
    • 打印记录器具有允许打印锤(20)摆动和横向移动以便提供打印锤(20)的打击表面(22)和台板(24)的平行对准的承印物锤头接头(32) 当打印锤(20)与最不相关的部件啮合时。 背书器锤头接头(32)包括具有底表面(35)的插座(34),用于接合插座(34)的柱塞(36),柱塞(36)具有接触底表面的端部(37) 和定位装置(38),用于将柱塞端部(37)弹性地定位在底面(35)上的初始位置中,并且还用于允许底面(35)相对于柱塞(35)摆动和横向移动 36)。
