Definitions
- the invention relates to a printer according to the preamble of claim 1.
- Printers of the type mentioned are referred to, for example from US Pat. No. 6,088,049 A, as clam shell printers.
- Printers of this type are characterized by a divided housing with a lower part and an upper part pivotably mounted thereon between an abutting position on the lower part and a position which releases a receptacle for a recording medium storage space.
- the parting plane between the housing parts lies in the pressure plane.
- a Clam Shell printer is also known, which is equipped with a cutting device for the recording medium comprising a fixed knife and an electromechanically displaceable knife.
- the fixed knife is arranged in the swiveling upper part and the movable knife together with the knife drive in the fixed lower part.
- the movable knife cannot return to its rest position if the paper is jammed in the cutting device.
- the swiveling upper part of the housing cannot be opened.
- the knife must then be brought into its rest position manually by turning a knurled wheel that is not easily accessible.
- the object of the invention is to propose a cutting device for a printer of the type mentioned in the introduction, in which blocking of the pivotable housing part is avoided.
- the object is solved by the features of claim 1.
- the printing device comprises a printer housing with a chassis lower part and a chassis upper part pivotably mounted thereon between a position lying against the chassis lower part and open.
- the upper part of the chassis is divided into a front region and a rear region, the front region about a near the upper front edge of the printer housing and parallel to this first pivot axis and the rear region around a near the upper rear edge of the printer housing and parallel is pivotable to this extending second pivot axis.
- An output slot for a recording medium is formed between the two regions of the chassis upper part, on which the cutting device is arranged, the lower knife being fixedly arranged in the front region of the chassis upper part and the upper knife being displaceably mounted in the rear region of the chassis upper part and a displacement drive for the upper knife is arranged.
- the rear area of the upper part of the chassis can be swiveled to the rear and the front area to the front.
- the two knives are also swung apart so that the jam is released as it were.
- the upper knife preferably has a V-shaped cutting edge or an oblique cutting edge with respect to the lower knife. This always results in only a punctiform separation point during the cutting process.
- the displacement drive is one of a knife motor Driven threaded spindle drive is formed, wherein a spindle nut is arranged on the upper knife.
- a simple reduction gear so that the cutting speed and the force to be applied by the knife motor are also determined by the pitch of the threaded spindle.
- the feed width of the upper knife can be determined via the current duration of the knife motor, so that when using a V-shaped or inclined cutting edge it is easily possible to selectively cut or cut the recording medium.
- the design of the displacement drive as a threaded spindle drive driven by a motor has the further advantage that, in the event of a jam, an attempt can first be made to pull back the upper knife with the force of the knife motor and only if this fails to generate a fault message.
- FIG. 1 is a pressure device according to the invention in the closed state in a sectional schematic side view
- Fig. 2 shows the printing device of Fig. 1 in the open state in a sectional schematic
- FIG. 3 shows an enlarged detail from FIG. 1.
- Fig. 1 shows a printing device 10 in the closed state in a schematic cut side view.
- the printing device 10 is enclosed by a housing, designated overall by 12, which consists of a floor pan 14, a lower housing part 16 and an upper housing part 18, the latter in one front area 20 and a rear area 22 is divided.
- the front region 20 is pivotable about a first pivot axis 26 running parallel to the upper front edge 24 of the housing 12 and the rear region 22 about a second pivot axis 30 running parallel to the upper rear edge 28 of the housing 12.
- the front region 20 lies snugly on the lower housing part 16 and is held in this position by the pivoted-down rear region 22 of the upper housing part 18.
- a recording medium output slot 23 is formed between the front region 20 and the rear region 22 of the upper housing part 18.
- the lower housing part 16 encloses a chassis lower part 34 and the rear region 22 of the upper housing part 18 a chassis upper part 36. The latter is articulated to the chassis lower part 34.
- the rear region 22 of the upper housing part 18 is snapped onto the upper chassis part 36 and can therefore be pivoted together with the latter about the second pivot axis 30.
- the chassis upper part 36 is acted upon by the force of an opening spring 32 in the opening direction (FIG. 3).
- a recess 38 Arranged in the rear area of the lower chassis part 34 is a recess 38 which is partially cylindrical in cross section and which is open at the top and serves as a receptacle for a recording medium supply roll 42, and whose cylinder axis 40 is horizontal and perpendicular to one of the recess 38 and the discharge slot 23 leading record carrier transport track 44 is aligned.
- an easily rotatable support roller 46 is provided on both sides of the trough base, the axis of which runs parallel to the cylinder axis 40.
- the transport device 48 comprises a transport roller 56 which has at least the width of the recording medium 54. It is mounted in the upper chassis part 36 and is drive-connected via a gear 58 to a feed motor 60 likewise arranged in the upper chassis part 36.
- the printing station 50 is equipped with a needle printhead 62 which is fastened on a carrier 64.
- the carrier 64 can be displaced on a carrier guide symbolically represented by a guide rod 66 with the aid of a carrier motor 68 along a platen 70 and at a predetermined distance parallel to the latter.
- a fixed but interchangeable ink ribbon cassette 72 is assigned to the needle print head 62 and is placed on an ink ribbon holder (not shown).
- the needle print head 62, the carrier 64, the carrier guide, the carrier motor 68 and the ink ribbon receptacle are arranged in the chassis lower part 34 and the platen 70 in the chassis upper part 36.
- An output slot 23 for a recording medium 54 is formed between the two areas of the upper chassis part.
- the cutting device 52 is arranged directly on the output slot 23. It consists of a fixed lower knife 74 attached to a knife holder 73 in the front region 20 of the upper housing part 18 and a movable upper knife 76, the latter being displaceable in the direction of the lower knife 74 with the aid of a knife motor 78.
- the motor shaft continues in a threaded spindle 80 which is in engagement with a spindle nut 82 attached to the upper knife 76.
- the upper knife 76 and the knife motor 78 are arranged in the rear region 22 of the upper housing part 18 on the chassis upper part 36.
- the upper knife 76 In one direction of rotation of the knife motor 78, the upper knife 76 is moved against the lower knife 74 into the position 76 'shown with broken lines and brought into the rest position shown with solid lines in the opposite direction of rotation.
- the upper knife 76 has a V-shaped or oblique cutting edge with respect to the lower knife 74.
- the feed width of the upper knife 76 can be determined via the duration of the current supply to the knife motor 78, so that when using a V-shaped or inclined cutting edge it is easily possible to selectively cut or cut the recording medium 54.
- Cutting devices of this type are known per se, which is why a description of the mode of operation is dispensed with.
- the rear region 22 of the upper housing part 18 can be folded back together with the upper part 36 of the chassis and the front region 20 can be folded forward.
- the two knives 74, 76 are also pivoted apart, so that the jamming is released as it were.
- a locking pin 84 projects vertically outward from the side walls of the upper chassis part 36. In the position of the upper chassis part 36 shown in FIG. 1, the locking pin 84 engages in a claw 86 which is incorporated into a flank of a locking lever 86 which can be pivoted about a pivot pin 84.
- the locking lever 90 tapers to an insertion bevel 92 for the locking pin 84.
- the locking lever 90 is acted upon by the force of a locking spring 94 in the direction of its locking position shown by solid lines.
- a locking spring 94 On the flank of the locking lever 90, into which the claw 86 is incorporated, one end of an unlocking slide 96 engages, the other end of which ends in an actuation button 98 embedded in the front wall of the lower housing part 16.
- the locking lever 90 By pressing the actuation button 98, the locking lever 90 is brought into its unlocked position shown in broken lines and the upper chassis part 36 swings, driven by the opening spring 32, together with the upper housing part 18 into the open position shown in FIG. 2. In this way, on the one hand, the two knives 74, 76 are separated from one another and a record carrier possibly jammed between the two is released. On the other hand, the trough 38 becomes accessible and a record carrier Drawing medium supply roll 42 can be inserted into this. The end of the recording medium 54 running from the latter is guided in the direction of the output slot 23 and held there. If the upper chassis part 36 is now brought into its closed position shown in FIG. 1, the transport roller 56 engages the recording medium 54. At the same time, the recording medium 54 lies against the platen 70.
