Definitions

  • the invention relates to an exchange device for a reloadable cassette, consisting of a ribbon wound as a supply spool and a spool core for the take-up spool, a typewriter or office machine of the type specified in the preamble of claim 1.
  • a removable cassette for a carbon ribbon in a printer with a rotatable drive element for feeding the ribbon has become known, the cassette consisting of a housing accommodating a supply spool and a take-up spool for the ribbon.
  • a swiveling feed roller interacts with a spiked wheel with a take-up spool arranged on a fixed axis in order to wind up the carbon strip.
  • the feed roller with the spike wheel must first be disengaged from the take-up spool. In this changing process, several manual operations are required, since the feed roller must also be brought back into engagement with the take-up reel after inserting a new cassette into the take-up device of the machine.
  • DE-PS-2 553 329 shows an ink ribbon cassette for a typewriter or office machine of a similar type, in which the feed roller with the sprocket wheel is arranged in the cassette.
  • the feed roller remains in constant engagement with the carbon tape of the take-up spool. This makes it possible to replace ribbon cartridges with only one hand.
  • This known ribbon cassette is very expensive, since the drive elements contained in the ribbon cassette for the carbon ribbon are also thrown away after their consumption. Since the feed roller is also always in engagement with the take-up spool and the drive elements are mounted on the one hand in the base part and on the other hand in the cover firmly connected to the base part, it is not possible to replace the feed and take-up spools.
  • US-A-4 367 963 also discloses a reloadable ink ribbon cassette with an opening closable cover. Since the core of the take-up spool is directly attached to the free end of the supply spool, threading the ink ribbon around deflection points within the cassette is thereby ruled out.
  • the invention has for its object to provide an exchange device for a reloadable cassette, consisting of a ribbon wound as a supply spool and a spool core for the take-up spool, which after inserting the supply spool and the core of the take-up spool into the opened ribbon cassette, easy threading of the ribbon allow for several deflection points in the cassette and a simple attachment of the ribbon end to the take-up spool without the operator having to have any particular skill or knowledge.
  • This object is achieved by the invention characterized in claim 1.
  • the guide pin After removing the used ribbon spools and inserting a new supply spool and the core of the take-up spool, the guide pin makes it easy and quick to thread the ribbon around deflection points in the cassette and securely connect the ribbon end to the core of the take-up spool.
  • the replacement of the ribbon spools is possible in a short time without special knowledge.
  • FIG. 1 shows a reloadable ink ribbon cassette 1, which consists of a pot-shaped base part 2 and a cover 3 which can be closed at the opening.
  • the cover 3 can in this case be connected to the rear wall 4 of the base part 2 in an articulated manner and can be locked to the front wall 5 by means of locking lugs (not shown).
  • a feed spool 7 is rotatably supported, of which an ink ribbon, for. B.
  • a one-time use carbon tape 8 can be unwound.
  • the carbon strip 8 can be steered via deflection bolts 9, 10, 11 to an outlet opening 13 with a deflection 12 and arrives via an deflection 14 again in an entry opening 15 of the cassette 1.
  • the carbon strip 8 is wound up via a deflection bolt 16 to a take-up spool 17 of carbon tape 8 passed.
  • the take-up spool 17 is rotatably supported with its core 18 on a bearing pin 19 of a holder 20.
  • the bearing bore 37 is designed as a blind hole, see FIG 17 always against a spike 23 on the floor 6 gela gerten feed roller 24 can be pressed.
  • the carbon belt 8 is securely wound onto the take-up spool 17 when the feed roller 24 rotates.
  • the free end 25 of the ribbon 8 of the full supply spool 7 has a fastening for a guide element for threading the ribbon 8 around deflection points 9, 10, 11, 12, 14, 16 in the cassette 1, which with the core 18 of the take-up spool 17 Winding the ribbon 8 is firmly connected.
  • the attachment is arranged at the free end 25 of a ribbon piece 49 which wraps around the ribbon roll 26 in an overlapping manner.
  • the attachment can e.g. B. be an eyelet 27 into which a guide pin 28 can be inserted.
  • the guide pin 28 can also be firmly connected to the band piece 49 by means of an adhesive connection.
  • the free end 25 of the band piece 49 can have an adhesive surface with which the guide pin 28 is firmly connected.
  • the free end 25 of the ribbon piece 49 holds the ink wrap 26 together with a fixed loop, such that the ink ribbon wrap 26 cannot be unwound.
  • the contact surfaces of the loop of the band piece 49 can be firmly glued to one another.
  • the core 18 of the take-up spool 17 has a fastening device for fastening to the free end 25 of the ink ribbon 8 on the feed spool 7.
  • the fastening device is a receiving bore 29 in the core 18 of the take-up spool 17, into which the guide pin 28 can be inserted.
  • the receiving bore 29 is also provided with a passage slot 30 to a recess 31 serving as a threading slot in the outer circumference of the core 18 of the take-up spool 17.
  • the guide pin 28 has, on the one hand, a guide tab 32 for guides 33, 34 of the base 6 in the base part 2, which protrudes from the width of the ink ribbon 8, and on the other hand a handle 35 for facilitating the threading of the ink ribbon 8.
  • the handle 35 is connected to the guide pin 28 via a material weakening 36, which favors the detachment of the handle 35 after the guide pin 28 has been inserted into the receiving bore 29.
  • the guides 33, 34 are arranged in the region of the deflections 9, 10, 11, 14, 16 in the base part 2 and have wall-shaped elevations.
  • the coil core 38 of the supply reel 7 is provided with a protruding handle 39 on the upper side.
  • the coil core 38 of the feed coil 7 has a recess 40 on its underside for receiving the handle 39. This makes it possible to stack several feed coils 7 on top of one another for safe storage.
  • a package 47 for the shipping and storage of the ribbon reels, a package 47 according to FIG. 3 is provided, which consists of a pot-shaped base part 41 and a cover 42 that can be closed.
  • the lid 42 and the bottom part 41 each have an opening 43, 44 for the passage of the handle 39, through which a stacking of the packages 47 is also ensured.
  • the packaging 47 is cuboid.
  • the core 18 of the take-up spool 17 is stored in the package 47 in one of the free corners between the pot-shaped base part 41 and the outer winding 45 of the feed spool 17.
  • the guide pin 28 connected to the free end 25 of the feed spool 7 can be connected to a wall 46 of the base part 41 e.g. B. be releasably connected by an adhesive connection.
  • the supply spool 7 is firmly connected to a toothed disk 48, in the toothing of which a locking tooth 52 of a spring-loaded 53 swivel lever 50 can be locked.
  • the deflection pin 10 is incidentally mounted on the pivot lever 50. If the carbon belt 8 is moved in the direction of arrow 65 according to FIG. 1, then the pivoting lever 50 is pivoted clockwise around the bearing pin 51 in such a way that the ratchet tooth 52 disengages from the toothed disk 48. As a result, the supply reel 7 is released for unwinding the carbon ribbon 8. When the tension in the carbon band 8 decreases, the locking tooth 52 comes into engagement with the toothed disk 48 again due to the force of the spring 53.
  • the toothed disc 48 can also be formed in one piece with the core 38 of the feed coil 7. As a result, the assembly of the feed spool 7 in the cassette 1 is made very easy. In addition, the toothed pulley 48 supports the full winding of the feed spool 7 in such a way that the winding cannot bulge out.
  • the holder 20 with the rotatably mounted take-up spool 17 needs to be brought out of engagement with the pin wheel 23 of the feed roller 24.
  • the disengagement of the holder 20 with the take-up spool 17 can take place via a pivot lever 54 which is pivotably mounted in a recess 55 in a side wall 56 of the base part 2 of the cassette 1. With the help of this pivoting lever, the holder 20 with the take-up spool 17 can be pressed into a detent position for decoupling the spiked wheel 23 with the outer winding 45 of the take-up spool 17.
  • This pivot lever 54 has a handle 58 on an arm 57 and a stop 60 on a second stop arm 59, which can be brought into engagement with the holder 20.
  • the stop arm 59 is provided with a resilient latching lug 61, which can be latched behind the latched edge 62 on the spring-loaded holder 20 in the latched position.
  • the holder 20 is unlocked again via the pivoting lever 54 in such a way that the sprocket 23 securely engages with the outer winding of the take-up spool 17 again.
  • this (55) Around the pivot lever 54 in the non-operative position to stick in the recess 55, this (55) has a notch 63, in which the pivot lever 54 can be locked with a locking edge 64.
  • the ribbon spools 7, 17 according to the invention enable simple replacement, the replacement parts no longer required requiring only a small amount of material.
