  • the recording sheet 92 coming from the pressure body 89 is guided with its sheet beginning into the loop-shaped sheet guide channel 99 and is brought up again to the sheet contact point 94 of the pressure body 89.
  • the length of the loop-shaped sheet guide channel 99 is dimensioned such that the beginning of the sheet of the recording sheet 92 reaches the sheet contact point 94 before the sheet end of the recording sheet 92 leaves the pressure body 89 at its sheet depositing point 96.
  • the recording sheet 92 is guided past the recording head 100 for the second time and the second partial image is thereby printed. This process is repeated until the last partial image begins to be printed.
  • the controllable switch 98 is controlled in the switch position shown in broken lines, so that the recording sheet 92 is conveyed out of the ink ribbon cassette through the opening 93.
  • the ribbon cassette shown has a sheet insertion slot 101 in its front outer width, through which recording sheets and special formats such as envelopes to be individually printed can be fed directly to the sheet placement point 94 of the pressure body 89.
  • the printed recording sheets can also be removed individually directly from the ink ribbon cassette by opening a sheet ejection slot 103 by actuating a flap 102 in the area of the transition from the guide element 96 in the sheet guide channel 99.
  • FIG. 7 shows a schematic representation of a modified embodiment of the ink ribbon cassette shown in FIG. 6 in the region of the controllable switch.
  • a step-by-step mechanism 105 is arranged in the course of the guide element 97 immediately in front of a switch 104 which, via a cam 106, switches the switch 104 either into a switching position which redirects the incoming recording sheet 92 into the sheet guide channel 99 or into the switching position 92 in the direction of the Opening 93 forwarding switching position controls.
  • the indexing unit 105 is designed as a toothed roller, the teeth of which protrude into the area of the blade guide immediately in front of the switch 104 in each switching position of the indexing unit 105.
  • the recording sheet 92 coming from the sheet depositing point 96 of the pressure body 89 therefore bumps with one of its teeth against one of the teeth of the toothed roller 105 and rotates it further by one switching position.
  • the cam 106 held on the toothed roller 105 is designed with regard to its eccentricity in such a way that it controls the switch 104 in a switch position diverting the recording sheet 92 into the loop-shaped sheet guide channel 99 with three switching positions of the stepping mechanism 105; in the fourth switching position of the indexing mechanism 105, the switch 104 is controlled in the switch position shown in broken lines, in which the recording sheet 92 in the direction of the opening 93 for transferring the recording sheet 92 out of the ink ribbon cassette 2 is leading.
  • the step mechanism 105 is particularly suitable if the four colors yellow, magenta, cyan and black are to be printed in succession for the color printing of the recording sheet 92.
  • the ribbon contained in the ribbon cassette is continuously provided with color sections in the colors mentioned.
  • ribbon cassettes can be provided for the possibilities of guiding the recording sheet to be printed within the ribbon cassette, such as the switch for multiple or multicolored printing of the recording sheet or the additional sheet insertion and sheet ejection slots for printing individual recording sheets, provided for in the exemplary embodiments described above , which can be plugged into the housing of the device depending on the desired function.
  • This also applies to ink ribbon cassettes that are designed for special formats of the recording sheets.
  • the ribbon stored in the ribbon cassette can be replaced in a simple manner after the ribbon cassette has been removed from the housing of the device.
