Description

The invention relates to a printer device according to the preamble of claim 1. The printer device comprises an ink jet printing device with an ink cartridge inserted into a cartridge carrier and a control unit which controls the printing. The cartridge carrier is mounted on a carriage which is moved back and forth during printing. The carriage may be controlled to change the ink cartridge to a predetermined position. The inserted ink cartridge is locked and can be unlocked and ejected by a mechanism mounted on the side of the cartridge holder. The printer device is suitable for 1 inch receipt printers and is used in franking, addressing machines and other printing mail processing equipment.

From the German patent application DE 102007060733 A1 a device for changing ink cartridges is already known, which has a transport device for flat goods, a pressure device and a printing module, wherein the transport device is stationary in the printing device relative to a pressure device which presses the mailpiece to the conveyor belt, which in the transport area with a predetermined static friction acts on a part of the surface of the mail piece, which is not printed, but is located near the area to be printed, with a change position for ink cartridges in front of the transport area on the front of the printing device or on the transport area of a correspondingly designed transport device.

The print module has a print carriage with two compartments for inserting ink cartridges. The ink cartridges have an on-the-belly front containing an ink reservoir. The print carriage of the printing module has an opening for insertion of the ink cartridges, which laterally through a right and left side plate and the bottom side by a carrier molding and the back is limited by a contact field of the contacting and control electronics. The carrier molding consists of two halves, which are offset from one another. A lock lever is rotatably attached to each of the right and left side plates. The printhead of each of the staggered ink cartridges is in a printing position during printing. The print carriage is configured to be moved forward transversely of the mailpiece transport direction from the print position to a change position. The change position is at the front of the printing device or above the transport area of a correspondingly designed transport device. The transport area lies on the front side of the printing device and the printing area adjoins it to the rear.

From the German patent application DE 102008033052 A1 An arrangement for replacing ink cartridges is known, which has a print carriage with a shaft-shaped receptacle for ink cartridges. The contact field of the contacting and control electronics on the back of each shaft has a number of mating contacts. The mating contacts are adjustably arranged and mechanically coupled to the latch of a locking mechanism so that at the same time with the unlocking of the ink cartridge, the mating contacts to the ink cartridge distanced and contacted with the locking of the ink cartridge, the mating contacts with the contact pad and a chip on the ink cartridge. The latch serves as a lock lever and cooperates with a locking lug at the edge between the narrow top and the narrow back of the ink cartridge, wherein the locking lug is adapted to the contour of the bolt.

In the European patent EP 1 880 857 B1 an arrangement has been proposed for the replacement of ink printing modules, the latter term ink cartridges are referred to, which can be used directly in a receptacle of the pivoting device. The arrangement has latch for locking the ink cartridges and per ink cartridge mechanically connected to a return spring towing hook and a guide lever. After replacement, the return springs pull the tow hooks back to a starting position. This mounted on the ink cartridge recording device for changing the ink cartridges is material-intensive and can be an unfavorable manual Operation of the towing hooks lead to a contamination problem, because the lower trailing edge of the nozzle surface of the ink cartridge is applied to a spring piece, which should prevent contact of the counterpart to the contact pad, the distance is so small that a contamination counterpart to the contact field can not be excluded. The fouling problem results from the fact that the distance is small and can contaminate the spring piece and the contacts when removing the ink cartridge by ink accumulated at the lower trailing edge during printing. The towing hook and the elaborate mechanism of the aforementioned prior art are disadvantageous for easy replacement of the ink cartridges.

In the German patent DE 10 2008 030 530 B4 An ink cartridge receptacle has been proposed which has neither draw hook nor the elaborate locking mechanism of the aforementioned prior art and in which the contamination problem is eliminated. The ink cartridge has been modified by a guide pin which is attached to the abdomen or between the belly and head of the ink cartridge and protrudes only on one side over the flat side wall to guide the ink cartridge. When inserting the ink cartridge, the guide pin slides in a guide slot in a wall of an ink cartridge receptacle, wherein a leaf spring in each provided for an ink cartridge cavity of the cartridge holder of the ink cartridge receptacle with inserted ink cartridge is biased and supported by spring force the replacement of the ink cartridge, if by hand pressure on the Ink Cartridge disengages the locking tab and the locking element of the ink cartridge carrier and the ink cartridge is pivoted about an axis extending parallel to the guide pin axis to unlock the ink cartridge, wherein the distance of the lower trailing edge of the ink cartridge to the contact field of the cartridge carrier determined by the course of the guide slot exactly is.

From the German utility model DE 202012005904 U1 A franking machine with an ink printing device is already known, to which a flat product is pressed by means of a pressure device, wherein the ink printing device contains interchangeable ink cartridges. Instead of a leaf spring, a compression spring is used in the ink cartridge receptacle, by the spring force of the replacement the ink cartridge is supported, after the locking tab and the locking element of the ink cartridge carrier are disengaged by hand pressure. One advantage of manual handling is that the ink cartridge is gripped by hand after loosening the contacts and therefore does not jump up so fast out of the cartridge carrier that ink cartridge reaches the open flap of the postage meter.

In a postage meter machine of the applicant type Mymail, which has a very small design, but there is not enough space in the cavity of the cartridge holder for receiving the ink cartridge neither for a leaf spring nor for a compression spring, see EP 1127701 B1 , When the franking machine is switched on, a lid can be opened at any time prior to printing, a release unlocked and the ink cartridge removed. During printing, the ink cartridge is moved and therefore can not be replaced. The cartridge carrier formed in a manner known per se from two side parts is mounted in a known manner on a carriage, which is slidably mounted on a guide rod. The outside of the right side part is hereinafter referred to as the so-called carriage side, since this is provided for mounting the cartridge carrier on the carriage. The outside of the left side member is referred to as the so-called terminal side, since this is provided for connecting a ribbon cable for conductive connection of the electrical connection contacts of the ink cartridge with the control unit. The mounted cartridge carrier has in a known manner an overhead opening for insertion of the ink cartridge in a cavity and an angled from the outer edge of the left and right side portion outwardly narrow wall. In a small design of the slide-guide cartridge carrier, a compression spring would be unsuitable for providing a force necessary to drive the ink cartridge out of the cavity. During the insertion of the ink cartridge into the cavity of the cartridge carrier of the ink cartridge receptacle, the compression spring would have to be realized in a strongly compressible manner, which requires additional space. It is further disadvantageous that the ink cartridge can be manually changed even when the cartridge carrier is rotated to a sealing position for the ink cartridge. The duck head could be damaged if the ink cartridge when pressed too far to push the locking edge of the ink cartridge past an edge on the opening of the cartridge carrier. This could damage the printhead of the ink cartridge if the service station is touched. All this is disadvantageous in manual handling of the ink cartridges.

It is an object to develop a printer apparatus which overcomes the disadvantages of the prior art when changing an ink cartridge, i. during the insertion and removal operation of the ink cartridge are eliminated. On the one hand, it should be ensured that the ink cartridge can only be exchanged if the cartridge carrier has previously been moved into a predetermined position for changing cartridges or is rotated when it passes from a sealing position into the interchangeable position. On the other hand, manual operator errors during the change are to be excluded. In this case, a solution for unlocking the ink cartridge is to be created without an operator having to touch the ink cartridge directly for this purpose or can. Damage to the duck head should be avoided. In particular, it should be prevented by a suitable design of a cartridge holder, that during insertion of the ink cartridge into the cartridge carrier, the ink cartridge can be pressed too deep into the cavity. By maintaining a slotted guide during insertion and movement of the ink cartridge into the cavity of the cartridge carrier against the spring action of a spring, a solution for an even smaller space is to be created than is available with the cartridge carrier PostBase® postage meter. After inserting the ink cartridge into an opening in the cartridge carrier, the ink cartridge is to be locked to the cartridge carrier. The ink cartridge should be unlocked before replacing it on the cartridge carrier.

A manual touch of the ink cartridge is to be avoided altogether until a time at the beginning of the removal operation of the ink cartridge from the cartridge carrier, wherein the time is reached only after a release of the electrical connection to the contacts of the ink cartridge.

A spring force should be effective not only to support the removal operation of the ink cartridge, but the effect of the spring force should also so limited and dimensioned so that the ink cartridge does not jump too far up out of the cartridge carrier before it can be grasped by hand. It is intended to prevent the ink cartridge moving upwards from striking the opened flap of the postage meter machine.

After unlocking and removing the used ink cartridge, the opening to the cavity in the cartridge holder should remain freely accessible until the opening for inserting another ink cartridge filled with ink is needed.

The object is achieved with the features of the printer device according to claim 1.

The cartridge carrier has a cavity for inserting an ink cartridge, and a locking and ejection mechanism is disposed on an outer side of a side part of a cartridge carrier. The outside of the other side part, called carriage side, on which a carriage is mounted. On the outside of the aforementioned side part, ie on the connection side for a ribbon cable, the locking and ejection mechanism is mounted. A right-handed printer device is the left side portion of a cartridge carrier when the printer device is viewed from the front.
The locking and ejection mechanism has a locking mechanism with a acted upon by a first spring with a spring force locking lever which is tiltable about an axis of rotation, wherein the axis of rotation is disposed lying on the outside of the side part. The locking and ejection mechanism further comprises an ejection mechanism with a at least acted upon by a second spring with a spring force lifting plate, which is arranged about a rotation axis rotatable on the outside of the side part, wherein the axis of rotation of the lifting plate is arranged standing on the outside of the side part. The lifting plate is acted upon by a spring force from a two-stage spring system, wherein the spring force is dimensioned so that an ink cartridge can be detached from the cartridge carrier, lifted and ejected.
The locking lever comprises a first locking means and a second locking means, wherein the second locking means is provided for locking the first locking means. An actuating means is provided for unlocking the locking of the second locking means. The lifting plate is rotatably arranged so far that the locking lever after ejection of a Ink cartridge is held in an unlocked position. The rotated lifting plate, which holds the locking lever in an unlocked position, prevents the nose can be locked unintentionally with the ink cartridge removed. In the same way, unintentional unlocking of the first locking means can be prevented by the second locking means.
In a housing part of the - viewed from the front - printing device actuating means above and adjacent to the ink cartridge is arranged so that a locked ink cartridge can be unlocked only when the locking and ejection mechanism in a predetermined position and at a predetermined distance D to a Tip of the actuating means is located. The locking and ejection mechanism has an unlockable by a release means locking mechanism. The release means can be triggered only in the predetermined position by the actuating means. For this purpose, before changing the ink cartridge, a printing carriage of the printing device must be moved to a side wall, which is provided for changing the ink cartridge or the print carriage must be stretched in this position. The print carriage has - in a known manner - a toothed belt and a carriage which slides on a guide rod, wherein the side of the print carriage, on which the carriage is mounted, hereinafter called carriage side. The other side is called connection side below.

For sealing and maintenance of the ink cartridge another position is provided. The latter is achieved after a print carriage has been moved with a cartridge inserted into the ink cartridge to a housing side wall and then the print carriage is rotated about an axis of the guide rod so that the cartridge carrier is tilted forward. A right-handed printer device is a right-hand side panel within the printing device viewed from the front. The release means of the forward tilted cartridge holder can then no longer be triggered by the actuating means, because the release means and the actuating means due to the rotation outside of that distance D advised that allows a release. Advantageously, damage to the print head of the ink cartridge can be avoided because in this position, the ink cartridge can not be replaced nor pressed too deep into the cavity. This will avoid it too Touching the maintenance station comes and the print head can be damaged.

The release means consists of a compression spring and a resilient hook carrier of a locking lever, wherein the hook carrier is provided with a release trigger surface and with a recess at the end of a snap hook is formed. The hook carrier is integrally formed on a connecting piece on the short lever arm end, wherein a bearing pin for the pressure spring is formed below the connecting piece at the short lever arm end. The release means and a cartridge locking lug are formed in a preferred variant on the upwardly directed end of the mounted locking lever. The snap hook is arranged in the outwardly angled narrow wall at the upper edge of the left side part of the cartridge carrier for the purpose of locking the locking lever in a window-shaped opening. The cartridge carrier has the following advantages and modes of action:

The insertion movement of the ink cartridge during insertion into the cartridge carrier is limited by means of one end of the slotted guide on the inside of the side part on the carriage side. This can prevent the ink cartridge from being pressed too deeply into the cavity, and a cartridge carrier with a very small design can be realized.

A tension spring of the ejection mechanism is arranged on the outside of the connection side of the cartridge carrier, instead of the spring previously used in the interior of the cavity, which has been mentioned above. The tension spring cooperates with a lifting plate, both of which form only part of the ejection mechanism. A small finger for lifting the ink cartridge is angled inwards on the lifting plate of the ejection mechanism, that is, directed into a space of the cavity. It is called a cartridge lift finger below and engages in a space in the area between the belly and neck of the ink cartridge. A spacer section at the bottom of the cartridge carrier has a recess for the cartridge lifting finger.

The ejection mechanism also includes a U-shaped plate having a downwardly directed end that is positively connected in the mounted state to a bottom plate on the terminal side of the cartridge carrier. The U-shaped formed sheet metal has two side parts and a central part with a flat base, in which a hole is incorporated near the other end. The U-shaped sheet metal is mounted on a mounting pin. The latter protrudes on the connection side of the cartridge carrier outward and through the aforementioned hole. The one side portion of the U-shaped sheet has a right angle bend with an abutment member for a compression spring at the end which is directed upward in the assembled state. The compression spring is attached at one end to a journal of a locking lever and is stretched at the other end and mounted on the counter-bearing element. Between the bottom surface of the downward side of the assembled U-shaped sheet and the outer surface of the terminal side of the cartridge holder, there is a gap in which the lifting plate of the ejection mechanism is movably mounted. The mounted lifting plate has two support wings in the middle. At one end of the lifting plate, a finger for lifting the ink cartridge is formed at an inward bend. In addition to the finger, a suspension hole for the tension spring at an outwardly directed bend of the lifting plate is arranged at the same end. At the other end of the lifting plate, a bearing hole is arranged. The lifting plate is mounted with its bearing hole on a bearing pin on the connection side, wherein the bearing pin allows a rotational movement of the lifting plate about an axis of rotation during ejection of the ink cartridge.

In the case of an inserted ink cartridge, on the one hand, a torsion spring engages the aforementioned lifting plate; on the other hand, the torsion spring is arranged on the outside of a side wall of the cartridge holder so that the spring force of the torsion spring acts only up to a stop formed on the connection side of the cartridge holder. The ink cartridge is removed from the cavity with a first force when the ejection mechanism is released. On the terminal side, that is, outside of the left side part of the cartridge holder, a lock lever is arranged so that a long downwardly directed lever arm of the lock lever is arranged adjacent to the U-shaped plate. At its end, the long lever arm on a control contour. A nose for cartridge locking is at the opposite end of a short lever arm of the Locking lever molded. Only when the carriage has been moved to a predetermined position for changing cartridges, the actuating means is positioned to the end of the short lever arm of the locking lever so that it can act on the lock lever and release it when actuated. A release means disposed between the actuating means and the locking lever can then unlock the locking lever upon actuation of the actuating means and thus release the ejection mechanism. The release means is in the preferred embodiment, a component of the locking lever. The release means consists in this variant of a compression spring and a resilient hook carrier, which has a release trigger surface and at the one in the direction of the cartridge locking nose end facing a snap hook is formed. The snap hook is located at a locking of the ink cartridge in a window-shaped opening in an upwardly angled from an upper edge of the left side panel narrow wall. The window-shaped opening is open towards the cavity, so that the nose protrudes into the cavity for cartridge locking. Upon actuation of the release trigger surface of the resilient hook carrier is pressed out of the opening and the compression spring is relaxed, whereby the locking lever is moved so that the cartridge locking lug does not protrude into the cavity. The ejection mechanism is released by relaxing the compression spring by the locking lever in a rotation axis tilts so that the end of the long lever arm is moved up to the left side wall of the cartridge holder. The control contour of the locking lever cooperates with the Aussteuerlappen the lifting plate so that the lifting plate performs a rotational movement about an axis of rotation. The ink cartridge is first accelerated to a speed by the spring force of the torsion spring acting on the lift plate and then a braking contour in the upper third of the groove of the slide guide on an inner wall of the cartridge carrier slows the further movement of the ink cartridge to the extent that the ink cartridge after can not move too far up. The spring force of the aforementioned tension spring supports the removal of the ink cartridge. However, it is too weak for the ink cartridge to be able to advance upwards out of the cartridge carrier so far that the ink cartridge touches the open flap of the postage meter machine strikes. To emphasize is the possibility of a very simple construction of the kinematic coupling of the actuating means with the locking lever. The actuating means mounted in the upper housing part is, for example, a button. The latter stands above the release trigger surface of the hook carrier of the release means when the ink cartridge inserted into the cartridge carrier has been moved to the predetermined position for replacement. Otherwise, the key and the release means are disengaged and can no longer interact.

The lift plate 61223 is rotatable about a journal 613 and disposed in a space between the U-shaped plate 6125 and the outer surface of the left side member 61. The pivot 613 is formed on the outer surface of the left side member 61 near the narrow front side edge and at the height of the center of the lower window opening 6245. The two legs of the torsion spring 61221 are each located on a stop 6161, (6162 see Fig. 9 ) at. The stops and a journal 616 for the torsion spring 61221 are on the outer surface formed of the left side part 61. Near the lower rear corner of the bearing pin 616 is arranged. The one stop 6161 for the one leg of the torsion spring 61221 is arranged above the bearing journal 616.

The FIG. 3a shows a front view of the cartridge holder 6 without ink cartridge. The cut wall of the side member 61 shows the locking and ejecting mechanism 612 disposed on the firing side of the left side member 61. The locking lever 61211 has a long lever arm 612113 terminating in a control contour 612118 which cooperates with a control tab 612232 of the lifting plate 612233 the latter holds the locking lever 61211 in an unlocked position. The illustrated unlocking state of the locking and ejection mechanism 612 is taken after the ejection of the ink cartridge and remains until an ink cartridge is re-inserted into the cavity. The locking lever 61211 is tiltably mounted about an axis of rotation 612110 on the Anschußseite the side part 61, wherein the locking mechanism 6121 has a short lever arm 612112 and a compression spring 61212, in the illustrated unlocking state between the short lever arm 612112 and a - not visible here - counterpoint on the one end of the U-shaped sheet is compressed, so that the spring is under a bias, which acts on the short lever arm. The short lever arm 612112 branches at the lever arm end into a nose 612111 and a connecting piece 612115, the nose 612111 facing the cavity and the connecting piece 612115 facing away from the cavity. The short lever arm is tilted in the illustrated unlocking state of the terminal side of the cartridge holder 6 away. The long lever arm 612113 of the locking lever 61211 is pressed against the outer surface of the side member 61 due to a control contour 612118 formed on its lever end, because the control contour 612118 of the control tab 612232 acts on the lever arm of a lifting plate 61223. The axis of rotation 612230 of the lifting plate 61223 is orthogonal to the axis of rotation 612110 of the locking lever 61211.

A detail B of the FIG. 3a is shown enlarged and shows a snap hook 6121163 at the end of a recess 6121162 a hook carrier 612116, which is integrally formed on the connecting piece 612115 of the locking lever 61211 is, wherein the snap hook 6121163 abuts on the Anschußseite of the side part 61 below the angled wall 611 of the side part 61 near the opening 610. A carriage 12 is mounted on the carriage side of the cartridge carrier 6, that is, the outer wall of the right side member 62.

The FIG. 3b shows a side view of the cartridge carrier after Fig. 3a from the left. An attachment portion 124 on a rear wall of the carriage is provided to secure a toothed belt (not shown) which is capable of slidably moving the print carriage back and forth on a guide bar (not shown). The locking and ejecting mechanism 612 has a locking mechanism 6121 which is unlocked in the state shown so that the opening for inserting an ink cartridge into the cavity of the cartridge carrier 6 remains open. The compression spring 61212 is compressed by the tilted locking lever 61211 only to the extent that a predetermined bias is maintained. The locking and ejecting mechanism 612 is mounted on the abutting side of the side member 61, the ejection mechanism 6122 of which consists of the torsion spring 61221, the tension spring 61222 and the lifting plate 61223.

The ejector mechanism 6122 is shown in a state after ejecting an ink cartridge from the cavity of the cartridge carrier 6. The tension spring 61222 and the torsion spring 61221 form a two-stage spring system which acts on the lever arm 612233 of the lifting plate 61223 before ejecting an ink cartridge from the cavity of the cartridge carrier 6. When the lock lever 61211 is unlocked (see 3a ), a cartridge lift finger 612237 on the lever arm end of the lift plate 61223 can lift the ink cartridge. Due to the course of the slide guide (see Fig. 2 ) on the side part 62 in the interior of the cavity, the ink cartridge is lifted from the front of the cartridge holder 6. The torsion spring 61221 is only effective until one leg of the torsion spring 61221 reaches the stop. The tension spring 61222 of the two-stage spring system is constantly effective. At the edge of the slotted guide 624 is a resilient arcuate portion 62431 (see Fig. 2 ) which slows the movement of the ink cartridge during ejection. After releasing the electrical Connection to the contacts of the ink cartridge is thus a time reached, which marks the beginning of the removal process of the ink cartridge from the cartridge carrier. A manual touch of the ink cartridge can thus be completely avoided by this time.

The lift plate 61223 has a bearing hole 612231, the control tab 612232 for holding the lock lever 61211 in the unlocked state shown, the lever arm 612233 with an angle piece 612236, and the cartridge lift finger 612237 at the lever arm end. The lifting plate 61223 is rotatably mounted with the bearing hole 612231 on a journal on the firing side of the side member 61. The tension spring 61222, which is fixed at one end in the spring retainer hole 6122360 of the elbow and at the other end to the bottom of the first compartment, is under a bias. The cartridge lift finger 612237 at the lever arm end of the lift plate 61223 engages through an arcuate opening 6114 of the left side member 61 and abuts against the upper end of the arcuate opening.

The FIG. 4a As a result of insertion of the ink cartridge 5, the cartridge lift finger 612237 at the lever arm end of the lift plate 61223 is depressed against the spring force action of the two-stage suspension system, and the short lever arm 612112 of the lock lever 61211 is urged by the spring force action of the compression spring 61212 the outer surface of the left side part 61 of the cartridge holder 6 is pivoted. As a result, the nose 612111 locks the inserted ink cartridge 5. After pivoting, the locking lever 61211 is held in the locking state shown by the snap hook 6121163, which now enters the opening 610. The snap hook 6121163 locks the nose 612111, which in turn locks the inserted ink cartridge 5. The nose 612111 can not be removed manually from the inserted ink cartridge 5 as long as the snap hook 6121163 engages the opening 610 (detail C). The spring-loaded hook support 612116 has a release release surface 6121161, which passes through the recess 6121162 of the snap-action hook 6121163 is removed. The snap hook is formed on an end of the hook carrier 612116 pointing in the direction of the cartridge locking nose. The actuating means 4 consists of the key 41, an operating lever 42, a wall 43 which is arranged below the first stage of the housing upper part and is shown cut and a compression spring 44. The operating lever 42 has a longer lever arm 421 and a shorter lever arm 422 and is tilted about a pivot axis 40. The button 41 has a downwardly molded release finger 411 at the one end of the longer lever arm 421. At the end of the shorter lever arm 422, a pin-shaped lower stop 4221 is formed, which extends in the same direction as the key 41 and on which the compression spring 44 is fitted. Upon actuation of the key 41, the actuating lever 42 acted upon by a spring force of the compression spring 44 tilts only until the stop pin 4221 abuts against the wall 43 under the first step of the upper housing part. An upper stop 4211 is formed on the long lever arm of the operating lever, wherein the stop 4211 extends in the same direction as the key 41 and is formed block-shaped. By the spring force of the compression spring 44, the stopper block 4211 comes into abutment against the wall 43 under the first stage of the upper housing part when the key is not actuated. The wall 43 has an opening 430 for the button 41 and a holder 431 (and 432 hidden) for the operating lever 42. The bracket 431 (432 hidden) has bearing holes 4310 (4320 obscured) for supporting two pivots 4231 (4232 occluded) of the operating lever 42. Upon ink carriage movement, an ink cartridge changing position is achieved. The release trigger surface 6121161 is - positioned after the movement of the print carriage or rotation of the cartridge holder - to the trigger finger 411 so that the latter when pressing the button 41 down the ends of the hook carrier 612116 - in a manner not shown - compresses. As a result, the snap hook 6121163 disengages from an inner edge of the opening 610 and the spring force of the compression spring 61212, which presses the short lever arm 612112 of the locking lever 61211 on the outer surface of the side part 61, is overcome and thus the nose 612111 released. In this case, a distance D to the release trigger surface 6121161 of the hook carrier 612116 is first overcome by a tip of the release finger 411 and thereafter the snap hook 6121163 disengages from the inner edge of the opening 610, the snap hook overcoming a stroke H, the stroke H being at least equal to the thickness of the angled wall 611 (FIG. Fig. 2 ) in the region of the opening 610 (detail C). Also, manufacturing tolerances must be considered, which is why the release stroke F must be increased by a safety tolerance S of about +1 mm. For the tip of the release finger 411 thus a release stroke F is provided, which results from a sum of distance D, stroke H of the snap hook and a safety margin S. The operating lever 42 has dimensions which ensure the necessary release stroke F. The stop pin 4221 of the operating lever 42 limits the release stroke F so far that the resilient hook carrier can not be compressed too far until it breaks. The nose and the resilient hook carrier are formed at one end of the short lever arm of the locking lever. At the other end of the long lever arm 612113 of the locking lever, a control contour is formed, which transmits the forces acting on the lifting plate 61223 spring forces by means of a Aussteuerlappens 612232 on the long lever arm 612113 of the locking lever. The long lever arm 612113 can then - in a manner not shown - act on the short lever arm of the locking lever and tilt it away from the outer surface of the side part 61. A release means disposed between the actuating means and the locking lever can thus unlock the locking lever upon actuation of the actuating means.
In the Fig. 4b is a side view of the cartridge carrier Fig. 4a , shown from the left. The actuating means 4 protrudes with the button 41 on the wall 43 also upward, because the compression spring 44 acts on the shorter lever arm 422 of the actuating lever which is tiltable about the rotation axis 40. The compression spring 44 is attached to the stop block 4221. The axis of rotation 40 passes through the pivot 4231, 4232 of the actuating lever. The pivot pins 4231, 4232 of the actuating lever are rotatably mounted in the bearing holes of the holder 431, 432.
