    摘要： An electronic typewriter has an electronic control circuit housed with the usual typing mechanism in a casing, and can be provided with a display module for displaying text and/or machine functions. The display module is removably fixed to the casing. An electronic unit for controlling the display module is removably fitted in the casing and is connected to the control circuit and the display module by connectors. A basic typewriter without a display module can be constructed with a cover instead of the display module. The two types of typewriter can be produced on largely the same production line, and the basic typewriter can be simply upgraded with a display module in the field.

    摘要： A cassette for a printing ribbon comprises a casing accommodating a supply spool which has a tube on which the printing ribbon is wound. An anti-unrolling element of plastics material comprises two portions of elongate shape, which are connected by means of an integral elastic hinge. The first portion performs a guiding and positioning function and is accommodated by means of a slot within the casing. The second portion has a blocking function with regard to the tube, and is movable on the outside of the casing, by means of the elastic hinge, from an inoperative position in which it is aligned with the first portion to an operative position in which it is rotated through 180.degree. and is substantially in superposed relationship with the first portion. The second portion is provided with a hook element which, in its operative position, engages the tube through an opening in the casing for positively blocking the supply spool both during storage and during transportation of the cassette to inhibit unrolling in a simple and reliable manner.

    摘要： The key comprises a movable part guided in a fixed support on a base plate and contacts which are closed when the key is depressed against the action of a return spring. The symbol associated with the key is displayed through a window in the key top by an LCD device with a matrix of display areas controlled by an integrated circuit bonded to the underside of the LCD device and fed with signals from the CPU via conductors which enable the integrated circuit to be programmed to define the symbol to be displayed, whereby the keys of a keyboard can be set to match the language currently being used. In an alternative embodiment the key is supported by a flat cable connected with an input circuit of the keyboard and the terminals of the LCD device.
