Definitions

  • the invention relates to a typewriter or office machine of a similar type for generating full-print characters and / or color images, graphic representations or patterns of the type specified in the preamble of claim 1.
  • Line drawing devices on typewriters for drawing horizontal and vertical lines are already known several times. The fact that they can hardly be found in practice should prove enough that they have not proven themselves enough or that the writing process was too difficult.
  • German patent specification 891 271 discloses a holding device on typewriters for receiving a threaded ballpoint cartridge, in which a threaded holder for receiving the writing cartridge is arranged by means of a clamp on the row plates to the right or left of the type guide head.
  • the row plate made of plastic has a threaded sleeve of the writing cartridge instead of an insertion hole.
  • Such an arrangement interferes with the writing process, in particular in the case of machines in which the print head is arranged on a carriage which can be moved along the record carrier. Replacing the ballpoint pen cartridges would also require a certain skill from the operator of the machine.
  • a multi-color writing instrument is known from German Offenlegungsschrift 33 15 733, in which pens of different colors are arranged on the periphery of a drum-like holder.
  • the setting of this writing instrument to one of the desired colors is very complex.
  • DE-OS 36 19 567 proposes a ribbon cassette with a sliding element having a colored pencil, which is arranged so as to be displaceable from a disengaged position into a ready position via a handle located thereon. With this it is possible to create simple lines in horizontal, vertical or in any other direction, but the adjustment of the displacement element still has to be carried out by hand. Therefore, this arrangement is not suitable for an automatic printer.
  • DE-PS 31 40 888 discloses a recording device with writing elements which can be displaced in the direction of the recording medium and which consist of colored pens and are arranged in a drum-shaped holder.
  • This known multicolor recorder is well suited for producing colored graphical representations or patterns, but is less suitable as a simple correspondence machine. It is also not possible to produce carbon copies with these known recording devices.
  • the invention has for its object to provide a typewriter or office machine of a similar type for generating full print characters and / or color images of graphical representations or patterns, the recording device for generating color images of simple components, easy to assemble and suitable for cheap mass machines is.
  • This object is achieved by the invention characterized in claim 1.
  • the recording device for generating color images can be used in the machine instead of the ribbon cassette.
  • This device can also be used in all typewriters that have already been sold. Therefore, this recording device for generating color images can either be bought with the machine at the same time or can be purchased at any time afterwards as a functional component.
  • Another advantage is that to drive this record nation device, the drive device already present in the machine can be used for other functional units.
  • FIG. 1 shows a type carrier carriage 7 which can be moved along a recording medium 1 on axes 3, 5 and on which, in addition to a type carrier 9, a drive device for transporting an ink ribbon 11 in typewriters or office machines of a similar type is arranged.
  • the ink ribbon guided from a supply reel 13 onto a take-up reel 15 is arranged in a cassette 17, which is arranged so that it can be fitted onto or removed from a receiving device 19 of the type carrier carriage 4.
  • the ink ribbon cassette 17 can be locked by means of a catch 21 of a locking pawl 23 pivotably mounted in the receiving device 19. This locking pawl 23 is pivotable about a bearing pin 25 and is acted upon by a spring 27.
  • a carrier plate 29 is arranged so as to be pivotable about a bearing axis 31, on which take-up spools for a correction tape 33 are arranged, of which only the front council reel 35 is shown.
  • the correction tape 33 coming from the correction tape reel 35 is deflected around a deflection guide 37, which is part of the pivotable support 29.
  • the take-up reel for the correction tape 33 and the corresponding drive device are not shown and described in more detail.
  • the take-up spool 15 for the ink ribbon 11 can be driven via a spike wheel 39 which, on the one hand, has a hand setting wheel 41 and, on the other hand, has a cross-slot-shaped recess for a cutting-shaped coupling element 43 in the receiving device 19 of the type carrier carriage 7.
  • the cutting-shaped coupling element 43 is cushioned in the axial direction and can be driven via a gear 45 which is in permanent positive connection with a gear 47.
  • This gearwheel 47 is rotatably mounted on a bearing journal 51 on a side wall 53 of the type carrier carriage 7 and has a toothing 49 which can be brought into engagement with clutch pawls 55, 57 in the direction of rotation of a drive gearwheel 59.
  • This drive gear 59 is also rotatably mounted on the journal 51 and can be driven via a drive pinion 61 which is fixedly connected to the drive shaft 63 of a drive motor 65.
  • the drive wheel 59 also has clutch pawls 67, 69 on the rear side, which drive a drive shaft 71 when the direction of rotation of the drive motor 65 is reversed, on the free end of which a gear wheel 73 is fixedly arranged.
  • a toothing 75 of this gear 73 is in constant engagement with a toothing 77 of a gear 74, which is firmly connected to a cam disk 79.
  • This cam disk 79 has an incorporated cam track 81, in which a guide pin 83 on the pivotable carrier 29 engages in a form-fitting manner. If the gear 81 is driven with the cam disk 79, then the carrier plate 29 is pivoted with the correction device.
  • FIGS. 3 and 4 show an XY recording mechanism 85, which can be placed on the receiving device 19 of the type carrier carriage 4 instead of the ink ribbon cassette 17.
  • This recording mechanism 85 has a receiving plate 87, which can be latched on the receiving device 19 and has a bearing block 89, in which a drum 91, with locking on its periphery in latching openings 93 and rotatably mounted in the direction of the recording medium (1) pens 95 is.
  • the drum 91 can be driven by a ratchet mechanism, which can be coupled to the ribbon transport device, for adjustment to a pen 95.
  • the drum 91 is provided with a toothing 97, the teeth 99 of which can be brought into engagement with a drive pawl 103 which can be displaced against the force of a spring 101.
  • This drive pawl 103 consists of a piston 107 which is displaceable against the force of the spring 101 in a hollow cylinder 105 and which has at one end a stop pin 109 projecting from the hollow cylinder 105 for a drive lever 111 and is provided with a leaf spring 113 at the other end is slidably mounted in a slot of the hollow cylinder 105 and its free end can be brought into engagement with the teeth 99 of the gear 97.
  • the sprung pawl 103 presses the drive lever 111 against a fixed stop 114.
  • the cam disk 125 is fixedly connected to a gear 131, the Teeth 133 with a toothing 135 of a drive gear 137 is engaged.
  • This drive gear is rotatably mounted in the bearing plate 87 and is firmly connected to a handle 139.
  • the drive gear 137 has, at least on its underside, a cross-slot-shaped recess 141 which can be positively coupled to the cutting-shaped coupling element 43 when the bearing plate 87 is placed on the receiving device 19 of the type carrier carriage 4.
  • the adjustment of the drum 91 with the longitudinally displaceable pens 93 can thus be driven both by means of the handwheel 139 and by means of the ribbon transport device with the coupling element 43, such that one of the colored pens 93 can be brought into the working position shown in FIG. 3.
  • the resilient lugs 145 are formed by recesses 151 in the spring washer 147 and act on the pens 95 in such a way that their ends facing away from the writers rest against a stop surface 153 of the bearing block 89.
  • This stop surface 153 has a recess 155 in which a two-armed pressure lever 157 is pivotally mounted.
  • This pressure lever 157 is pivotally mounted about a bearing axis 159 and has on one arm 161 a pressure surface 163 for loading the pens 95, while the other arm 165 has a stop pin 167 for the carrier plate 29 with the correction device. Incidentally, the pressure lever 157 is held in the rest position by means of a spring 169 with a stop lug 171 with the surface of the carrier plate 87.
  • this (87) is provided with a contact edge 164 in slots of the side walls of the type carrier carriage 4, the insertion being limited by the abutment of stop lugs 173, 175 against protruding stops 177, 179 on the side walls of the type carrier carriage 4.
  • the side plate 87 is locked at the side by side stop lugs 181, 183 which rest on the outer surfaces of the side walls of the type carrier carriage 4.
  • the mounting plate 87 can be pivoted about the plug connections in the direction of the arrow 185 until the mounting plate 87 comes to rest with its underside on contact surfaces 187, where a pawl 189 with a locking lug 191 then locks the mounting plate 87.
  • This pawl 189 is arranged pivotably about a bearing pin 193 against the force of a spring 195. This pawl 189 also serves as a locking pawl for the ribbon cassette 17 when the ribbon cassette 17 is placed on the receiving device 19 of the type carrier carriage 4.
  • the pens 95 are held securely on the one hand in bearing bores 197 in the gear 97 and on the other hand by resilient locking pawls 199 and 201 in the locking recesses 93.
  • a release device for the pens 95 is also provided on the receiving plate 87.
  • a release lever 203 is rotatably and displaceably mounted on a bearing pin 205.
  • This unlocking lever has a hand-operated handle 207 and a stop pin 211 on a second arm 209.
  • This stop pin can be pushed under the free ends of the stylus 95 by moving the unlocking lever in the direction of arrow 213, after which the stylus 95 is then automatically unlocked by the latches 109, 201 by pivoting the unlocking lever 107 clockwise.
  • the unlocking lever is reset by a spring 215 which is articulated in such a way that the unlocking lever is both rotated counterclockwise and is pushed back into the starting position on the bearing axis 205.
  • the pivoting movement of the unlocking lever 203 is limited by a stop pin 217 which engages in an elongated hole 219 of the release lever 203.
  • the transmission of rotation of the drive gear 137 to the gear 133 triggers a rotary movement of the cam disk 125 in the counterclockwise direction, as a result of which the drive lever 111 is pivoted in the clockwise direction and thereby displaces the drive pawl 103 in the direction of arrow 129.
  • the drum 91 is acted upon by the drive pawl 103 and the toothing 97 until the desired pen is in the working position.
  • the pressure lever 157 is then pivoted counterclockwise about the bearing axis 159 until the stylus with its writing tip comes to rest on the recording medium 1.
  • the pressure lever 157 is pivoted via the pivot plate 29, which acts on the stop pin 167 on the pressure lever 157.
  • the positioning of the pen 95 is thus carried out via the swivel plate 29 with the correction device, which is already present on the machine.
  • the swiveling of the swivel plate 29 in turn takes place via the drive motor 65, which counteracts set to the direction of rotation for ribbon transport.
  • the rotation is transmitted here via the clutch pawls 67, 69 to the drive shaft 71, from which the cam disc 79 is then acted upon by the cam disk 81 via the gear wheels 73 and 74.
  • the guide pin 83 on the swivel plate 29 is acted upon for the swivel movement thereof.
  • the typewriter according to the invention enables the generation of full-print characters and / or color images of graphic representations or patterns with the simplest means, the ink ribbon cassette 17 being simply replaced by a recording mechanism 85 with colored pens 95. Therefore, this recording mechanism 85 can also be used retrospectively on machines that have already been sold.
