Abstract: Ink cartridge (10) which is insertable (insertion direction 11) into an inkjet printer, or cartridge receptacle associated therewith, and which has a housing (13) on at least one wall (12) of which there is arranged a plate (21) comprising electrical contacts (20) and an element for storage of cartridge-specific and/or printer-specific data. The housing (13) is delimited by two side walls (17, 18), a top wall (15), a base wall (16) and a front and rear (end) wall (12, 14). At least that portion (12?) of the housing wall, especially of an end wall (12), which is associated with the plate (21) has a smaller width than the plate (21). The latter is, in addition, mounted to allow its movement transversely to the longitudinal extent of the associated housing wall (12), or transversely to the insertion direction (11) of the cartridge (10) (double-headed arrow 24).
