In order to facilitate the setting of the type wheels 1, a pointer 18 , which extends over the circumference of the type wheels 1 and is axially displaceable in the housing 2 secured against rotation, is mounted on the wrench shaft 7 in the vicinity of the setting wheel 9. The tip 19 of the pointer 18 always points to the type wheel 1 which is in engagement with the driver 6 and to the reading number 17 of the print type of this type wheel which is in the printing position.

The printed work shown in Figs. 4 and 5 consists of five
Type wheels 1 'together, which only print types 16 but

To facilitate the setting of the printing types 16, an indicator disc 25 is used, which is firmly connected to the setting wheel 9 and on the circumference of which numbers 24 or digits are arranged which correspond to the printing types 16 of the type wheels 1 '. For example, there is the lesezai ^. , Jj'4 "is in the read position, then the print type" 4 "of the type wheel 1 ·, in which the driver 6 ¹ engages, is in the print position. /
