    • The apparatus for mounting a daisy-wheel character carrying disc (70) in a printing machine comprises a frame (22) which is pivoted on a guide (13) of the carriage (12) that is parallel to the platen roller (11) and on which are mounted a selector motor (15) with which the character carrying disc is to be coupled, a striker hammer (16) and a pocket (60) into whichthe character carrying disc is inserted. A manually actuable mechanism (40) causes the frame (22), striker hammer (16) and the selector motor (15) to swing away from the platen roller (11) and at the same time causes the pocket (60) to be lifted, thus permitting the character carrying disc (70) to be removed and/or inserted from above. Coaxial coupling between the motor shaft (76) and the disc (70) and positioning of the disc between the platen roller and the striker hammer are effected automatically by manually actuating the mechanism (40) connected to the frame (22) to swing the frame back again towards the platen.
    • 用于在打印机中安装菊花轮字符传送盘(70)的装置包括:框架(22),该框架在托架(12)的与压纸辊(11)平行的引导件(13)上枢转,并且 其上安装有用于连接字符传送盘的选择器马达(15),用于插入字符传送盘的撞击锤(16)和凹槽(60)。 手动致动机构(40)使得框架(22),撞击锤(16)和选择器马达(15)摆动离开压纸滚筒(11),同时使袋(60)被提升 ,从而允许从上方移除和/或插入字符传送盘(70)。 电动机轴(76)和盘(70)之间的同轴耦合以及盘在压辊和撞锤之间的定位通过手动致动连接到框架(22)的机构(40)来自动实现,从而使框架 再次朝向压板。

    • A printer employing a daisy-type type wheel (27). On a hub (28) of the type wheel a pin (40) is slidably disposed and is backwardly biased by a spring (41) to protrude from the rear surface of the hub. In a central opening (32, 33) of the hub a hair pin spring (34) having a pair of arms is disposed. The type wheel is fixed on a drive shaft (2a) of a motor (2) through a coupling element (4). The coupling element is provided with a projection (5, 6) which is fitted into the opening of the hub and engaged with the arms of the hair pin spring by snap action to latch the type wheel against the drive shaft in axial direction. In the axially latched state the pin is protruded from the front surface of the hub, resisting the resilient force of the spring, by the coupling element. When the coupling element is rotated more than one time the protruded pin is engaged with a stationary projection (18) to prevent the type wheel from rotating, with a result that the pin is aligned with a notch (7) formed on the coupling element and fitted into the same for latching the type wheel against the drive shaft in rotational direction.
