A holding arrangement for the supply roll 6 of a tape-shaped recording medium is firmly arranged on the stationary part 1 of the cover of a printer. The holding brackets 2 are provided with bearings 22 which are open in the upward direction. Into these bearings there is inserted a tubular roll carrier 5 on which the supply roll 6 is supported in a freely rotatable manner. The holding brackets 2 are provided with rotatable latch bodies 3 by which the bearings 22 which are open towards above, can be closed. The latch bodies 3 are rigidly in connection with one another via a paper-deflecting yoke 4. In the turned up state of the yoke 4, the bearings 22 which are opened towards above, are unlatched. In order to enable the use of supply rolls of different widths A and B, one of the supporting brackets 2 is provided with a detachable spacing plate 7. By re-plugging the spacing plate 7, the clear spacing in relation to the other supporting bracket 2 can be adjusted to either of the widths A or B of the respective paper roll.

A continuous ink ribbon cassette for, for example, a serial printer in which a ribbon is kept in stacked loops in a vertical housing and is twisted on leaving and re-entering the housing so as to bring it into a vertical plan as it passes a print head. The ribbon leaves the housing through an opening at one end and passes round a vertical roller at the other end. After passing the print head, the ribbon is returned to the housing via a second vertical roller at the opposite end and an opening at the opposite end. The ribbon thus executes a figure 8 configuration and has the entire length of the housing in which to change its attitude from horizontal to vertical or from vertical to horizontal.

Keyboards designed in accordance with ergonomic viewpoints are slightly dished transversely in relation to the longitudinal direction and the key surfaces have a slope tending toward the dished shape. According to the invention, this arrangement is accomplished with the aid of adapters located between the key element plungers and the keyheads. For each row of keys there is provided a special type of adapter. The types of adapters differ from one another in their effective heights and in the slope angles of the supporting surfaces for the keyheads.
