Description

The invention provides a tachograph for Record information about vehicle speed and the route of a vehicle on a registration sheet and in particular a structure for inserting and removing a Registration sheet carrier in the tachograph which the Insertion and removal of the registration sheet carrier allows.

A widely used tachograph for recording Information about the vehicle speed and route is the so-called tour recorder with a housing opened and closed which meters how Odometer and speedometer houses and the one in the Instrument panel-mounted recorder housing is installed.

However, this tour writer has the disadvantage that due to being mounted on the front of the case Measuring devices, such as odometers and speedometers, that The registration sheet is located on the back of the housing, so that it is parallel to the scales of the gauges. The one from that Clerk on the instrument panel occupied area is large so that other gauges located on the instrument panel for reasons of harmony almost as big as the registration sheet must be, whereby the freedom of design of the Instrument panel is eliminated.

The applicant of the invention suggested one Box tachograph in front of that in the instrument panel be installed together with the audio equipment for vehicles can, and in which a basket or cassette with a rotatable plate for horizontal holding of Registration discs, d. H. a registration sheet carrier that Holds register sheet rotatable, in a recorder housing inserted or pulled out of this, the Measuring devices are formed separately from the cassette.

The tachograph proposed by the applicant according to of the invention is when incorporated into the instrument panel is only accessible to the driver at its front. Because of that are an opening for inserting or pulling out the cassette in or out of the recorder housing, a cover to the ingress of dust through the opening into the interior prevent a clock showing the location of the recording the registration sheet on which the vehicle operating information recorded, shows the corresponding time, and different control and display units in particular located on the front surface of the recorder housing. Therefore the design of the front surface of the box-shaped recorder housing heavily on the design its remaining surfaces.

The general adoption of a box-shaped Case structure - in which upper and lower case halves be put together or in which the upper and lower Surfaces of the box are designed to be open and then covered with a cover - for the Tachograph is not useful when you have that Difficulty in forming the front surface and the other surfaces considered, which are structurally strong have different designs. In the case of the Box tachograph is the case in particular in a Front panel and a rear housing divided, whereby for the rear case is an ordinary box-shaped construction is taken over.

When the front panel is made as an independent part , complex designs of the Front panels can be easily created. This construction will also preferred from the current standpoint.

A tachograph is known from DE 195 44 919 A1, its recording sheet carrier designed as a cassette a receiving opening inserted through the housing or can be taken from this and its front in is essentially covered by a hinged cover plate. The cover plate is by means of a at the bottom of the Front panel arranged hinge pivotally attached, whose cylindrical joint sections together with the cover plate of the Protrude from the front panel. If the cover plate is the front panel covers, grab the locking tabs at the top of the Cover plate are formed in one within the housing arranged locking mechanism. To fold down or A locking mechanism must be actuated to open the cover plate will.

Taking into account the box tachograph together with the vehicle's audio equipment in the Instrument panel is to be installed, it is desirable that the size of the recorder housing, especially the vertical ones Dimensions should be made as small as possible because im Instrument panel only limited space is available.

However, the registration sheet carrier adopts a mechanism on the one place on the registration sheet where the Vehicle operating information is recorded, moved on according to the actual time, d. H. the mechanism which rotates the registration sheet according to the actual time. This is reducing the vertical height of the Recorder housing limited.

When designing the front panel, it is important that the necessary components, such as clock and control and Display units, as efficiently as possible around the opening to be arranged - this section takes up the most space -, through which the carrier is inserted or withdrawn to minimize the vertical dimension. In particular, will preferred that components other than the opening specially arranged for example above the opening, thus only the minimum space required below the opening must be provided.

Because the instrument panel in which the tachograph installed in a lower position than the Driver, it is easier for the driver to remove the cassette to be inserted into the carrier or removed from it, if there is a generous free space above the girder. Therefore, the cover has a structure that folds down on instead of a structure that folds up and the For this reason, the cover can be rotated at its lower end attached.

To rotatably attach the cover to the front panel follows that the hinges that hold the cover on the front panel at the bottom of the opening on the front panel should be trained. To determine the vertical height of the To minimize front panels such as the recorder housing is located only a minimal portion of the Front panels. About the strength of the hinge area ensure the lower surface of the front panel, which connects to the front surface, a certain Have depth in the longitudinal direction.

Due to the opening formed in the front panel there is virtually no front panel area that is associated with the The bottom is connected and therefore there is only a narrow one Connection area, with an L-shaped cross-section, at the Underside of the front panel, which has a higher strength than the recorder housing has a small cross-section is. It is therefore important that the front panel has a certain Has depth in the longitudinal direction because with a small depth of the Front panels in the longitudinal direction deform the lower Surface inwards or outwards not can be controlled.

However, if the front panel is using a for complex designs of suitable shape must be made the front panel be provided a cast bevel to make it out of the To be able to draw form. This cast slope leads to an increase the vertical height of the front panel from the front Surface of the front panel to its back. Therefore, the Task of reducing the vertical height of the front panel and with it not the recorder housing due to the cast bevel can be fully achieved even if the hinges of the Cover are arranged at the lower end of the opening.

Under these circumstances, the invention has been completed. At a box tachograph in which a cassette with Recording paper through a cover opened by means of a cover or locked opening loaded horizontally or out of it is discharged, it is an object of the invention to provide a structure for inserting and removing recording discs in the Tachograph to create which ones are required Dimensions for inserting or removing a cassette can ensure the required strength of the Can ensure the hinge area of the cover and the Keep the vertical height of the recorder housing as a whole small can.

This task is solved with a tachograph, at which means a recording sheet carrier on a holder of a motor between an insertion / removal position outside of the recorder housing in which the recording sheet carrier can be used or removed, and a recording position can be moved within the recorder housing, in which Vehicle operational information on the registration sheet recorded with the recorder housing a Front panel with a front panel and a bottom panel having an opening formed in the front panel is through which the holder is passed when he between the insertion / removal position and the Recording position is moved, and which to the lower Edge of the front plate is open to which the front End of the base plate is adjacent, and with a cover for Opening and closing the opening is arranged, which is attached to the Shape of the opening is adapted and with its lower end pivotable from arranged at the front edge of the base plate Hinges is carried, and the holder at its front End has a driver portion which is spaced above of the hinge is arranged and with the cover to their Open cooperates.

This makes it possible for the opening to be inserted and removing the holder required vertical height ensure the hinges of the cover with the To reinforce the base plate area of the housing sufficiently, and the vertical height of the recorder housing as a whole to decrease.

According to one embodiment of the invention, the holder is with its underside arranged directly above the base plate, when the holder is in the insertion / removal position.

According to a further embodiment of the tachograph is a biasing means for biasing the open cover in whose closing direction between the front end of the Base plate and the lower end of the cover provided. The counter force exerted on the cover by the holder acts when the cover against the biasing means to Closing the cover is biased and rests against the holder, is reduced in the same way as the force with which the holder presses against the cover to open it. Therefore, when the cover is opened, the in Closing direction acting biasing means on the cover and thus reduced forces acting on the hinges increasing the vertical dimension of the Base plate area of the housing to reinforce the hinges is avoided. Therefore, the vertical height of the The recorder housing can be slightly reduced as a whole.

According to a further development, the holder is on his front end provided with guide projections that the Form driver section. The force with which the front The end of the holder pressing against the cover is less than when it pushes close to the hinges because of the guide tabs of the holder, which extends from the front end of the holder extend at the front, rest against the cover from behind. Since that front end of the holder on a portion of the cover is applied, which one of the axis of rotation of the cover has a certain distance, the acting on the hinge can Force can be reliably reduced.

In the middle of the rotatable plate 19 is a mounting axis 19 a, the outer diameter of which corresponds to the inner diameter of the central openings 21 b and 21 f of the recording disks 21 a and the cardboard 21 e and whose height is greater than that of the recording disk holding member 21 g. The erected assembly axis 19 a has in its central part a positioning projection 19 b with a recessed area 19 c in the middle. At the end of the mounting axis 19 a, the outer region of the positioning projection 19 b is provided with a removable cap 19 d.

In the registration sheet receptacle 18 b a cutting tool 18 c is provided in order to separate the described recording disks 21 a of the 7-day registration sheet 21 and lift it up. The cutting tool 18 c is made of a thin elastic metal sheet and has, as shown in FIG 16 shown comprises:. A foot portion 18 d, which is fixed to the front of the cassette case 18, the front face that side embodied with which the cartridge into the cartridge Luke 13 y is used; and a cutting body 18 e, which is bent away from the foot region 18 d and extends inward into the recording sheet receptacle 18 b, as can be seen from FIG. 14.

The cutting body 18 e is inclined so that the part of the cutting body 18 e near the foot region 18 d from the bottom of the recording sheet receptacle 18 b is greater than the thickness of the 7-day recording sheet 21 and that the cutting body 18 e with its end progressively the bottom of the registration sheet receptacle 18 b approaches until the end of the cutting body 18 e touches the ground. A stop member 18 f protrudes from the cutting body 18 e near the foot region 18 d.

The cutting body 18 e is deflected in order to produce a gap between the front end of the cutting body 18 e and the bottom of the recording sheet receptacle 18 b. While the outer edge portion of the 7-day recording sheet is inserted in this gap 21, the registration disc retaining member, 21 g is about the mounting shaft 19 a of the rotary stretchers plate 19 is inserted and the cap 19 is d plugged into the mounting axis 19 a. The cap 19 d presses the recording disk holding member 21 g on the rotatable plate 19 , thus holding the 7-day recording sheet on the rotatable plate 19 .

While the 7-day recording sheet is rotated on the rotatable plate 19 in the direction shown by the arrow A in Fig. 15, the cutting tool 18 c causes a recording disk on which recording has been stopped with the incision 21 c over the cutting body slipping and at the same time the cutting body the connection strip 21 cuts through j which the registration plate 21 a-described fixed 21 s at the support board to the described recording disc 21 a from the other recording disks 21 a and separate 21 e of the support board.

The cutting tool is designed in such a way that the cutting body 18 e adjoins the stop member 18 f, when the edge of the incision 21 c of the recording disk 21 a described has slipped over the cutting body, the rotation of the recording disk 21 a described is terminated, so that the recording can be continued immediately on the next registration disc 21 a located below the incision of the recording disc described.

As can be seen from Fig. 17, the side of the cassette housing 18 has a shutter 18 g. At the front of the cassette case 18, a gear is mounted h 18 as shown in Fig. 16.

At a point that is opened and closed by the shutter 18g is a driven gear (not shown) which is supplied with drive energy to rotate the rotatable plate 19 in the recorder housing 1 in accordance with the actual time. This driven gear meshes with a gear of the rotatable plate 19 via a transmission (not shown).

The gear 18 h engages in the above-mentioned translation via a different translation (not shown). When the gear 18 is rotated in a direction determined by a unidirectional clutch provided in one of the two ratios, the time adjustment of the 7-day registration sheet 21 , which is in the rotatable disk, can be performed 19 is held.

On the underside of the cassette housing 18, two pushing protrusions 18 are formed j (see FIG. 19). An engaging portion 18 k for engaging the holder 31 is formed in the front portion of the bottom of the cassette case 18 .

The engagement area 18 k has the following: a substantially rectangular locking groove 18 m, which extends with a predetermined width and length from front to back, two locking projections 18 n, which are in the locking groove 18 m near the end and at a distance in the direction of the width the locking groove 18 m are formed from each other, and an evasion groove 18 p which is formed in the rear end of the locking groove 18 m behind the locking projections 18 n.

The locking groove 18 m and the evasion groove 18 p are formed in the bottom of the cassette housing 18 with the same depth. The locking projections n 18 are as shown in Fig. 20 can be seen an inclined surface r 18, the height of which increases progressively from the front of the cassette case 18 to the rear side thereof and a locking surface 18 s, which almost vertically from the top of the inclined surface 18 r to the locking groove 18 m drops. The height of the locking projections 18 n corresponds to the depth of the locking groove 18 m and the evasion groove 18 p.

From FIGS. 17 and 20 it can be seen that the underside of the cassette case 18 has inclined surfaces 18 t, whereby they are formed by cutting both sides of the bottom of the cassette case 18 near the front at an angle.

Fig. 21 shows an exploded perspective view of the recorder housing 1. In the recorder housing 1, a holder 31, in which the cartridge 17 is of the cassette hatch 13 Y in the recorder housing 1 is inserted, and a transport mechanism 41 is provided, which transports the holder 31 between the cartridge hatch and the interior of the pen housing. 1

The holder 31 (corresponding to the carrier) comprises: a bottom plate 32 on which the cassette is placed from the cassette hatch 13 y, a transport plate 33 connected to the bottom plate 32 , side plates 34 , from the sides of the bottom plate 32 rise, and holding plates 35 and 36 which are bent from the upper ends of the side plates and extend inward.

As shown in FIG. 22, the dimensions of the base plate 32 correspond to those of the underside of the cassette 17 , which is inserted into the cassette hatch 13 y from the front. At the rear end of the base plate 32 , which is arranged in the rear section of the recorder housing 1 , two stop members 32 a protrude.

A U-shaped recess 32 b is formed between the stop members 32 a and extends towards the front side, as can be seen from FIG. 23. In the base plate 32 , a rectangular window 32 c is also formed at a distance forward from the front end of the recess 32 b.

On both sides of the recess 32 b and 32 c of the window guide openings 32 d (which with supporting means cooperating) formed, the c extending from the rear end of the window 32 b extend to the front end of the recess 32nd These guide holes 32 d are provided at their front ends with circular portions 32 e and have a shape like keyholes.

The forked areas 37 a of a spring plate member 37 are attached to the underside of the base plate 32 on both sides of the recess 32 b. A locking member 37 b of the spring plate member 37 is connected to these forked areas 37 a and arranged at the rear end of the window 32 c. A sharply bent portion of the locking member 37 b is arranged along a line connecting the front ends (opposite to the circular portions 32 e) of the guide holes 32 d, and protrudes downward from the underside of the bottom plate 32 through the window 32 c, as can be seen from FIG . At the rear end of the right side of the bottom plate is a provided with a Abrutschschutzloch 32 f supporting part 32 is formed on the bottom plate g 32nd

As apparent from FIG. 21, the transport plate 33, a base plate 33 a, which is disposed on the underside of the rear section of the bottom plate 32, and a support plate 33 d, which extend sideways on the underside of the bottom plate 32 from the right end of the base plate 33 a extends, wherein the front end of the support plate 33 d extends beyond the support part 32 g also.

The base plate 33 a is formed like a frame with a window 33 b therein. On the base plate 33 a attached to the rear end of the underside of the base plate 32 , guide pins 38 protrude on both sides of the window 33 b facing the guide holes 32 d and a hook 33 c is formed in the latter near the rear end of the base plate 33 a. The support plate 33 d has a stepped locking part 33 e, which extends from a position near the edge of the support plate 33 d and at the end of which an actuation part 33 g protrudes.

The transport plate 33 is mounted as follows: A locking part 33 e is guided from the bottom to the top through the anti-slip hole 32 f of the base plate 32 . A projection 33 f at the front end of the locking part 33 e engages in the side edge of the anti-slip hole 32 f, as can be seen from FIG . At the same time head portions are led 38 a of the guide pins 38 from the bottom to the top through the circular portions 32 e of the guide holes 32 d. A coil spring 39 is attached to the locking hole 32 g formed in a region of the base plate 32 between the recess 32 b and the window 32 c and to the hook 33 s of the base plate 33 a. The transport plate 33 is thereby mounted on the base plate 32 .

The transport plate 33 mounted on the base plate 32 is held in the normal position by the spiral spring 39 , the spiral spring 39 exerting a restoring force on the hook 33 c of the base plate 33 a in the direction of the locking hole 32 g of the base plate 32 so that the guide pins 38 adjoin the front side of the guide holes 32 d opposite the circular areas 32 e. In this normal position, the recess 32 b and the window 32 c are above the window 33 b.

The side plates 34 have near the bottom plate 32 inclined surfaces 34 a and vertical surfaces 34 b, which extend perpendicularly from the inclined surfaces 34 a upwards. An outline corresponding to the outline of the cassette 17 with the inclined surfaces 18 t is thereby formed. Each of the vertical surfaces 34 b has three guide pins 34 c, 34 d, 34 e which are spaced apart in the longitudinal direction of the base plate and which protrude from the surface of the holder 31 ( FIG. 22).

From the front ends of the vertical surfaces 34 b guide projections 34 f protrude, which can touch a part of the back of the cover 14 over the hinge, not shown. The front parts of these guide projections 34 f extend such that the distance between them increases progressively towards the front end.

An engagement part 34 g is formed between the two front guide pins 34 c on the vertical surface 34 b of the left side plate 34 and extends into the holder 31 .

Which is arranged on the left side of the bottom plate holding plate 35 includes a base plate 35 a, which is connected to the side plate 34, and a guide plate 35 b, which extends from the front end of the base plate 35 a to the front. A distance corresponding to the height of the cassette 17 is formed between the base plate 35 a and the base plate 32 . The base plate 35 a extends essentially parallel to the base plate 32 . The guide plate 35 b is inclined, as can be seen from FIG. 24, so that it has a progressively greater distance to the front from the base plate 32 and its front end is arranged higher than that of the base plate 35 a.

The holding plate 36 on the right side of the bottom plate 32 comprises a base plate 36 a, a guide plate 36 b, which extends from the front end of the base plate 36 a to the front, c an alternative plate 36 extending from the side of the base plate 36 on the retaining plate to 35 extends, an L-shaped outer edge of plate 36 d, the b and the free end of the alternate plate 36 is connected to the front end of the guide plate 36 c, and a connecting plate 36 e, which from the guide plate 36 b, the alternate plate 36 c and the outer edge plate 36 d is delimited.

Between the base plate 36 a and the base plate 32 , comparable to the base plate 35 a of the holding plate 35 , a distance corresponding to the height of the cassette 17 is formed. The base plate extends essentially parallel to the base plate 32 . The guide plate 36 b is inclined, comparable to the guide plate 35 b of the holding plate 35 , so that it has a progressively greater distance from the base plate 32 towards the front.

The evasive plate 36 c shown in FIG. 25 is inclined so that its distance from the base plate 32 increases progressively towards its free end, ie towards the holding plate 35 . The outer edge of plate 36 d extending substantially parallel to the bottom plate 32 and has from the bottom plate 32 upward at the same distance as the front end of the guide plate 35 b of the holding plate 35th

The connecting plate 36 has an opening 36 e f for absorbing by different tilt directions between the guide plate 36 b and the alternate plate 36 c to stresses caused, whereby a clamping of the holding plate 36 avoided.

When the cassette 17 is inserted into the holder 31 of the embodiment described above, the stop member 18 f of the cutting tool 18 c of the cassette 17 slides into a gap between the left and right holding plates 35 and 36 . As the cassette 17 is pushed in further, the apex of the inclined surface 18 r of the locking projections 18 n deflects the spring plate member 37 and slides over the locking part 37 b, a clicking sound being generated when the cassette 17 is fully inserted into the holder 31 .

When the cassette 17 is completely inserted into the holder, the locking projections 18 n are locked in the rear end of the base plate 32 and at the same time the locking grooves 18 m formed on both sides of the locking projections 18 n adjoin the circular surfaces of the head regions 38 a of the guide pins 38 , whereby the guide pins 38 are located at the front end of the base plate 32 in the normal position of the transport plate 33 . This abutment, combined with the locking of the locking projections 18 n by the spring plate member 37, positions the cassette 17 in the longitudinal direction with respect to the holder 31 .

When the cassette 17 positioned in the longitudinal direction in the holder 31 is pushed in further, the guide pins 38 , the head areas 38 a of which touch the locking groove 18 m, are moved towards the circular areas 32 e of the guide holes 32 d. As a result, the transport plate 33 with the guide pins 38 which protrude from the base plate 33 a, together with the cassette 17, is moved towards the rear end of the holder 31 against the restoring force of the spiral spring 39 .

Further insertion of the completely inserted cassette 17 positioned in the longitudinal direction on the holder 31 is prevented by two stop members 32 a at the rear end of the base plate 32 , to which the front surface of the cassette 17 is adjacent.

In this state, the locking part 37 b of the spring plate member 37 of the holder 31 engages in the evasion groove 18 p on the underside of the cassette 17 and the head areas 38 a of the guide pins 38 of the transport plate 33 are closer to the front than the circular areas 32 e. Therefore, the transport plate 33 is displaced from the normal position into the insertion position, the coil spring 39 , which was not loaded, assumes a tensioned state.

When no more pushing force is exerted on the cassette 17 , the transport plate 33 is moved from the insertion position into the normal position by the restoring force of the tensioned spiral spring 39 . The cassette 17 returns to the state fully inserted into the holder 31 , the locking surface 18 s of the locking projections 18 n of the cassette 17 being locked by the locking part 37 b of the spring plate member 37 and the head regions 38 a of the guide pins 38 to the locking groove 18 m adjoin.

When inserting the cassette 17 , the engaging part 34 g of the left side plate 34 engages and opens the shutter 18 g, exposing the driven gear (not shown) in the cassette housing 18 before the cassette 17 reaches the fully inserted state.

When the cassette 17 is removed from the holder 31 , the engagement of the engagement part 34 g in the shutter 18 g is released, which is then closed by the force of a spring (not shown) in the cassette housing 18 .

The transport mechanism 41 (which cooperates with a transport means) has an inner frame 42 , which supports the holder 31 , and an outer frame 46 , which supports the inner frame 42 , as can be seen from FIG .

As can be seen from FIG. 26, the inner frame 42 comprises a bottom plate 43 and side plates 44 which protrude from both sides of the bottom plate 43 .

The base plate 43 is made so wide that it can receive the base plate 32 of the holder 31 . At the rear end of the base plate 43 a cutout 43 a is provided, which prevents interference with the transport plate 33 when moving between the normal position and the insertion position.

On the left edge of the cutout 43 a at the rear end of the base plate 43 , a support 43 b with a rack 43 c is formed, which transmits a drive force for transporting the holder 31 to the inner frame 42 . A light protection 43 d protrudes from the rear edge of the support 43 b to the rear.

The side plates 44 comprise a front part 44 a at the front end and a rear part 44 g at the rear end. The front part 44 a has an inclined surface 44 b near the bottom plate 43 and a vertical surface 44 c, which extends vertically upwards from the inclined surface 44 b to form a contour cooperating with the contour of the side plate 34 of the holder 31 . The height of the front part 44 a is greater than that of the side plate 34 .

In the vertical surface 44 c, a guide groove 44 d is formed, which is open to the front and extends towards its rear end, to the rear downward, the inclined surface 44 b progressively closer. At the upper rear end of the vertical surface 44 c, two steps 44 e and 44 f are formed. The height of the upper step 44 e near the front end of the side plate 44 is substantially equal to the height of the open end of the guide groove 44 d.

The rear part 44 g extends continuously behind the vertical surface 44 c of the front part 44 a. In the front portion of the rear part 44 g, two steps 44 h and 44 j are formed. The height of the lower step 44 h near the front part 44 a is substantially equal to the height of the lower step 44 f of the front part 44 a. At the rear end of the side plate 44 , a further step 44 k is formed in the rear part 44 h, the height of which is essentially the same as that of the lower step 44 h.

In the rear part 44 g, a guide groove 44 m similar to the guide groove 44 d is formed, which is open towards the rear end of the higher step 44 j near the rear end of the side plate 44 and towards its rear end, towards the bottom rear, the base plate 43 progressively approaching extends.

At the front end portion of the rear part 44 g near the lower step 44 h, a guide pin 44 n extends outward from the inner frame 42 . At the rear end section of the rear part 44 g near the step 44 k, a guide screw 44 p is screwed into the inner frame 42 from the outside.

In the inner frame 42 constructed as described above, the longitudinal distance between the guide grooves 44 d and 44 m of the front part 44 g of the side plates 44 is essentially the same as the longitudinal distance between the guide pins 34 c and 34 e of the side plates 34 of the holder 31 .

The outer frame 46 includes a base plate 47 and side plates 48 which extend vertically downward from both sides of the base plate 47 .

The base plate 47 is considerably longer than the base plate 32 of the holder 31 and laterally somewhat wider than the base plate 43 of the inner frame 42 .

On the underside of the base plate 47 is a recording mechanism (not shown) for recording the operating data of a vehicle on the 7-day registration sheet 21 , which is accommodated in the registration sheet receptacle 18b of the cassette 17 , and a drive source (not shown) for operating of the recording mechanism such as a stepping motor. On the upper side of the base plate 47 (as can be seen from FIG. 8) a board 65 is fastened by a spacer 65 a and a mounting screw 65 b at a distance from the upper side of the plate.

Electrical components (not shown) such as a microcomputer 81 for controlling the operation of the recording mechanism and the operation of the transport mechanism 41 are mounted on the board 65 . These electrical components are arranged between the circuit board 65 fastened on the surface of the base plate 47 and the base plate 47 .

On the underside of the circuit board 65 , a fork-shaped photo interrupter 66 is fixed, which is open at its two forked end portions, between which light is transmitted and received (not shown). The two bifurcated ends of the photo interrupter 66 on the board 65 attached to the surface of the base plate 47 are spaced apart in the lateral direction of the outer frame and are open at the bottom. The free ends of the photo interrupter 66 protrude through an opening 47 f formed in the front right section of the base plate 47 below the base plate 47 .

As shown in Fig. 28, at the front right end of the base plate 47, a support 47 a is arranged bent so that it extends downward. A microswitch 51 is provided on the support 47 a, which is fastened in such a way that a switch part 51 a faces the rear end of the outer frame 46 .

At the left rear end of the base plate 47 , a mounting part 47 c is formed on a laterally extending extension 47 b, as can be seen from FIG . A motor 70 for the transport mechanism 41 is fastened to the mounting part 47 c. On the underside of the extension 47 b, gears for transmitting the driving force of the motor 70 to the rack 43 c of the inner frame 42 are attached (not shown). From Fig. 21 is a bent from the base plate mounting portion 47 is formed apparent d, on which the board is fixed by screwing the 72nd

As can be seen from FIG. 8, a support plate 64 is designed to be suspended from the front end of the base plate 74 . On the support plate 64 can be rotated about an axis 63 gear 61 is arranged having an arcuate light blocking plate 62, which rises from the outer edge of the surface of the gear 61.

As can be seen from FIG. 27, the side plates 48 each have a forwardly extending region 48 a near their front end. The front ends of the areas 48 a are spread out, so that the distance between them increases progressively towards the front end.

Near the lower end of the side plates 48 are two longitudinally extending Innenrahmenführungsnuten 48 b and 48 c formed along a line. In the front part of the side plates 48 above the inner frame guide groove 48 b, an L-shaped holder guide groove 48 b is formed with a longitudinally extending groove 48 e and a vertical groove 48 f which extends upward from the rear end of the longitudinal groove 48 e, as shown in FIG . 28 visible.

On the lower edge regions of the side plates 48 , apart from the front end regions, engagement parts 48 g are formed which engage in the engagement grooves 3 d of the base plate 3 of the lower housing part 2 .

The front ends of the inner frame groove 48 b and the longitudinal groove 48 e of the holder guide groove 48 d extend into the front end piece of the forward-widening areas 48 a. The rear end of the longitudinal groove 48 e of the holder guide groove 48 d is arranged closer to the front end of the side plates 48 than the rear end of the inner frame guide groove 48 b.

The holder 31 and the transport mechanism 41 are assembled as follows:
The rear guide pin 34 e on each side plate 34 of the holder 31 is first placed on the upper edge of the step 44 j of the two steps 44 h and 44 j of the rear part 44 g of each side plate 44 of the inner frame 42 . At the same time, the middle guide pin 34 g is placed on the upper edge of the higher step 44 e of the two steps 44 e and 44 f of the front part 44 a of each side plate 44 of the inner frame 42 .

Then when moving the holder 31 to the rear end of the inner frame to the front guide pin 34 c of the holder 31 to the opening of the guide groove 44 d, which is formed in the front part 44 a of each side plate 44 of the inner frame 42 , moved so that the guide pin 34 e on the step 44 j approaches the opening of the guide groove 44 m.

Then the rear guide pin 34 e guided through the upper edge of the step 44 j is pushed into the guide groove 44 m. At the same time, the front guide pin 34 c is pushed into the guide groove 44 d, whereby the holder 31 is mounted in the inner frame 42 . The position of the guide pin 34 e in the guide groove 44 m is essentially the same as the position of the guide pin 34 c in the guide groove 44 d.

The middle guide pins 34 d of the side plates 34 of the holder 31 mounted in the inner frame are between the higher step 44 e of the front part 44 a and the higher step 44 j of the rear part 44 g and above the lower step 44 f of the front part 44 a and the lower step 44 h of the rear part 44 g near the front part 44 a.

Then, the central guide pins 34 d of the side plates 34 of the holder 31 mounted in the inner frame 42 are inserted into the longitudinal grooves 48 e of the holder guide grooves 48 d which are formed in the side plates 48 of the outer frame 46 . At the same time, the guide pins 44 n of the inner frame are pushed into the inner frame guide grooves 48 b of the side plates 48 .

Since the distance between the front ends of the side plates 48 increases towards the front, it is not necessary to enlarge the gap between the side plates 48 when the guide pins 34 d of the holder 31 and the guide pins 44 n of the inner frame 42 in the longitudinal grooves 48 e the Halterführungsnuten 48 d and in the Innenrahmenführungsnuten 48 b at the front end of the side plates 48 are inserted.

After the guide pins d 34 of the holder 31 and the guide pins 44 n of the inner frame 42 in the longitudinal grooves 48 e of Halterführungsnuten 48 d and are inserted b into the Innenrahmenführungsnuten 48, the lead screw 44 p from the outside into the rear end of the rear part 44 g of near the step 44 k of the inner frame 42 screwed.

The microswitch 51 is attached to the support 47 a of the outer frame 46 in which the inner frame 42 receiving the holder 31 is mounted. The support plate 64 is designed to be suspended from the underside of the base plate 47 . The gear wheel 61 is mounted on this support plate so that it can rotate about the axis 63 . At the same time, the circuit board 65 on which the electrical parts of the recording mechanism (not shown) and the photo interrupter 66 are arranged is fixed on the base plate 47 of the outer frame 46 .

The motor 70 is attached to the mounting part 47 c of the base plate 47 . The gear ratios not shown are attached to the extension part 47 b and the output shaft of the motor 70 is connected to the rack 43 c of the inner frame 42 via the gear ratios.

By reversely rotating the motor 70 of the transport mechanism 41 , the inner frame 42 is moved forward relative to the outer frame 46 to position the guide screw 44 p at the front end of the inner frame guide groove 48 c. Thereby, the guide pins 34 d and 44 48 n in the front end portion of the Halterführungsnut d and the Innenrahmenführungsnut 48 b near the areas 48 a but are displaced so far from the front end of the grooves rearwardly so that the guide grooves 48 d and 48 b not the surface of the outer ends of the guide pins 34 d and 44 n are separated, as can be seen from FIG. 28 (in particular, the guide pins 34 d and 44 n engage with the guide grooves 48 d and 48 b).

When the guide screw 44 p is located at the front end of the inner frame guide groove 48 c, the guide pins 34 c and 34 e of the holder 31 are located in the rear ends of the corresponding guide grooves 44 d and 44 m of the inner frame 42 . The holder 31 is in the insertion / ejection position with the bottom plate 32 of the holder 31 on the bottom plate 43 of the inner frame 42 and with the guide projections 34 f of the side plates 34 of the holder 31 forward over the ends of the side plate 44 of the inner frame 42 protrude.

When the transport plate 33 is in the normal position, the actuating part 33 g of the transport plate 33 engages in the switching part 51 a of the microswitch 51 in order to turn it on. When the transport plate 33 is in the insertion position, the actuating part 33 g is removed backwards from the switching part 51 a in order to switch off the microswitch 51 .

When the forward rotation of the motor 70 moves the inner frame 42 backward relative to the outer frame 46 , the guide pin 44 n and the guide screw 44 p is guided backward along the inner frame guide grooves 48 b and 48 c. Corresponding to this movement, the guide pin 34 d of the holder 31 is guided backwards along the longitudinal groove 48 e of the holder guide groove 48 d of the outer frame 46 , the holder 31 moving backwards together with the inner frame 42 relative to the outer frame 46 .

As seen from Fig. 29, there is the guide pin 44 n and the lead screw 44 p in front of the rear end of the Innenrahmenführungsnuten 48 b and 48 c, when the guide pin d 34 of the holder 31 to 48 e of Halterführungsnut 48 d at the rear end of the longitudinal groove of the outer frame 46 is located.

When the holder 31 moves backward in the insertion / ejection position together with the inner frame 42 relative to the outer frame 46 , as described above, the actuating part 33 g of the transport plate 33 is removed backward from the switching part 51 a of the microswitch 51 and thereby the microswitch 51 switched off.

Further forward rotation of the motor 70 moves the inner frame 42 further backward relative to the outer frame 46 . The rear end of the longitudinal groove 48 e prevents further backward movement of the guide pin 34 d and a backward movement of the holder 31 together with the inner frame 42 is avoided. Only the inner frame 42 moves backwards.

Since the inner frame 42 moves backwards relative to the outer frame 46 , the guide pins 34 c and 34 e of the holder 31 are moved relative to the inner frame 42 from the rear end of the corresponding guide grooves 44 d and 44 m to their front end, whereby the guide pin 34 d is moved from the lower end of the vertical groove 48 f of the holder guide groove 48 d of the outer frame 46 to the upper end thereof.

The holder 31 is moved upward relative to the inner frame 42 and the outer frame 46 . When the guide pin 44 and the guide screw 44 n p the rear ends of Innenrahmenführungsnuten 48 b and 48 c reach reaches the guide pin 34 d almost simultaneously the upper end of the vertical groove 48 f, as shown in Fig. 30 can be seen. As a result, the bottom plate 32 is lifted upward from the bottom plate 43 of the inner frame 42 and the holder 31 is moved into the recording position. In the recording position, the right and left holding plates 35 and 36 are below the recording mechanism attached to the outer frame 46 .

When the holder 31 is in the recording position, the front ends of the side plates 44 of the inner frame 42 are retracted rearward from the front ends of the portions 48 of the outer frame 46 . The front ends of the guide projections 34 f are further withdrawn rearward from the front ends of the side plates 44 .

Fig. 30 shows a positioning pin 74e which extends downward from the underside of the base plate 47 to position the cassette 17 inserted in the holder 31 in the recording position. The positioning pin 47 e is designed such that it can be inserted into the round positioning projection 19 b of the mounting axis 19 a of the rotatable plate 19 in the cassette 17 inserted into the holder 31 in the recording position.

The circuit board 10 is fastened to the receiving plate 8 of the upper housing part 5 by screws. The actuating lever 54 extends from part of the receiving plate 8 to the right side of the board 10 so that it can be rotated about the axis 53 . The spiral spring 58 is pushed over the part of the axle 53 protruding above the receiving plate 8 . The locking member 57 is attached to the upper end of the axle 53 and the ends of the coil spring 58 are attached to the locking member 57 and to the receiving plate 58 . The photo interrupter 66 mounted on the board 65 is placed at the location of the light shielding plate 62 which moves when the gear 61 is rotated.

The angular position of the gear wheel 61 with respect to the support plate 64 is adjusted so that the light shielding plate 62 is located between the two forked end regions of the photo interrupter 66 . Screws, not shown, are inserted from below into the four corners of the base plate 47 of the outer frame 46 and screwed into the vertically downwardly extending round projections of the four corners of the underside of the cover plate 6 of the upper housing part 5 to mount the holder 31 and the transport mechanism 41 on the Housing upper part 5 with the side plates 48 of the outer frame 46 , which are directed towards the front end, to be attached.

The circuit boards 65 and 10 are connected to one another by a connecting cable 67 which is passed through the opening 7 a of the connecting plate 7 (see FIG. 7).

The pin 52 is arranged in a forward position, the toothing 56 a of the toothed region 56 of the support lever 54 engaging the gear 61 and the side edge of the support lever 54 resting on the step of the underside of the receiving plate 8 . In this state 52, the pin from the gap between the guide plate 36 of the support plate b 36 (which at the right side of the holder 31 in the insertion / ejection position is located) and the side plate 34 inward toward the bottom plate 32 in front and is nearer on the left side plate 34 than on the right side plate 34 .

In this state, with the protruding pin 52 on the inside of the right side plate 34 of the holder 31 , the light shielding plate 62 of the gear 61 is located between the two forked ends of the photo interrupter 66 and interrupts the light (not shown) and switches the photo interrupter 66 off. Here the cassette 17 has not yet been inserted into the holder 31 , which is therefore empty.

When the cassette 17 is inserted into the empty holder 31 , both side surfaces of the cassette housing 18 of the cassette 17 touch the inner surfaces of the vertical surfaces 34 b of the side plate 34 , which exert a minimum holding force from the holder 31 on the cassette 17 that is required to to move the cassette 17 along with the holder 31 in the longitudinal direction. In the very first step of inserting the cassette, before the minimal force is applied to the cassette, the cassette 17 pushes the pin 52 from the front end of the outer frame 46 towards the rear end and rotates the support lever 54 against the force of the coil spring 58 and pushes the pin 52 to the outside of the side plate 34 of the holder 31 .

When the support lever 54 is rotated by the pin 52 and pushed outwards, the gear 61 engaging in the toothing 56 a of the toothed area 56 is rotated and the light protection plate 62 , which was located between the two forked ends of the photo interrupter 66 (see Fig. 18), withdrawn from between the two forked ends of the photo interrupter 66 , as shown in FIG .

The light path of the photo interrupter 66 interrupted by the light protection plate 62 is thereby released, whereby the photo interrupter 66 is switched on. Therefore, it is determined by the photo interrupter 66 that the cartridge 17 has been completely or incompletely inserted into the holder 31 .

In contrast, the motor 58 rotates the spiral spring to the support lever 54 opposite to the direction in which it was rotated during insertion of the cartridge 17 when the cartridge inserted into the holder 31 17 is pulled out from the holder 31, not to the holding force of the holder 31 more acts on the cassette 17 . The pin 52 pushed to the outside of the side plate 34 returns to the inside of the side plate 34 .

The cover of the return of the pin 52 rotation of the support lever 54 rotates the gear 61, wherein said remote from the light path of the photointerrupter 66 light blocking plate 62 returns to a position in the light path of the photointerrupter 66, and turns off the photointerrupter. With the aid of the photo interrupter 66 , it is determined that the cassette 17 is not loaded in the holder 31 and the holder 31 is empty.

As can be seen from Fig. 2, fastening screws 81 are inserted from below into the mounting parts 13 z of the front plate 13 of the front panel 11 in which the lock 13 d is fastened. The self-tapping fastening screws 81 are screwed into the bottom openings (not shown) in the corresponding screw receiving openings 8 a of the receiving plate 8 of the upper housing part 5 in order to fasten the front panel to the front end of the upper housing part.

As can be seen from FIG. 32, an intermediate piece of the actuating lever 13 r of the lock 13 d is arranged above the switch 10 a mounted upwards on the board 10 in this state.

The key 13 A inserted into the keyhole 13 g of the cylinder 13 f is turned around in order to rotate the cylinder 13 f from the normal position to the open / close position against the force of the spiral spring 13 w, the intermediate piece of the operating lever 13 r is rotated around the pin 13 v and the switch 10 a is pressed to turn it on, as shown in FIG .

When the cylinder 13 f is released from the rotating force exerted by the key 13 A, the cylinder 13 f returns from the rotated position to the normal position by the force of the spiral spring 13 w, with the intermediate piece of the actuating lever 13 r upwards from the switch 10 a is removed, as can be seen from FIG .

When the front panel 11 is attached to the front end region of the upper housing part 5 , an adjusting knob 13 c of the clock is arranged in front of a switch 10 b which is directed forward and which is attached to the circuit board 10 . Pressing the setting button 13 c causes it to touch the switch 10 b and turn it on. Letting go of the setting button 13 c allows the setting button 13 c to move forward from the switch 10 b to turn it off. An indicator lamp 13 x is arranged in the front panel 13 to be exposed to the front.

Both sides of the lower region of the cover 14 are fastened together with the spiral spring 3 f by pins to the hinges 3 e at the front end of the base plate 3 of the lower housing part 2 , as can be seen from FIG . The lower housing part 2 is arranged under the upper housing part 5 with the cover 14 open to the front and is fastened to the front panel 11 , the holder 31 and the transport mechanism 41 in such a way that the upper housing part and the lower housing part are aligned in the longitudinal direction.

For this purpose, the engagement parts 16 a of the mounting plates 16 are inserted in advance into the mounting grooves (not shown) of the recessed areas 9 a of the side plates 9 of the upper housing part 5 . The engagement parts 16 b of these mounting plates 16 are inserted into the mounting grooves 4 b of the recessed areas 4 a of the lower housing part 2 while the lower housing part 2 is placed under the upper housing part 5 in order to fasten the mounting plates 16 on both sides of the upper housing part 5 and the lower housing part 2 .

The engaging parts 16 a and 16 b of the mounting plates 16 inserted into the mounting grooves of the upper housing part and the lower housing part are pressed outwardly into the assembly grooves by thrust pieces 9 c and 4 c of the upper housing part 5 and the lower housing part 2 from the recorder housing 1 . The thrust pieces 9 c and 4 c are arranged on the recessed areas 9 a and 4 a on the side of the mounting plates 16 and in contact with the rear side. Loosening of the mounting plates 16 in the direction of the recorder housing 1 inwards or outwards is avoided.

After the mounting plates 16 are attached to both sides of the upper housing part 5 and the lower housing part 2 , the ends of the round projections 9 b on both sides of the front of the upper housing part 5 are inserted into the receptacles 3 a of the lower housing part 2 and the engagement parts 48 g of the side plates 48 of the Outer frame 46 are inserted into the engaging grooves 3 d formed in the upper surface of the bottom plate 3 of the lower housing part 2 . The fastening screws 68 are inserted from under the base plate 3 through openings (not shown) in the lower housing part 2 through the sections of the base plate 3 in which the round projections 3 a are formed into the round projections 3 a. The self-tapping fastening screws are then screwed into the bottom openings (not shown) of the round projections 9 b of the upper housing part 5. This connects the upper housing part 5 and the lower housing part 2 to one another at the front and the hinges 3 e on the front of the lower housing part 2 are the lower end of the front plate 13 of the front panel 11 is covered and cannot be seen from the outside. When the cover 14 is released in the open state, the biasing force of the spiral spring 3 f turns the cover into an upright position until the cover 14 is locked by a stopper (not shown) formed on the inside of the cassette hatch 13 y of the front panel 13 of the front panel 11 and is brought into a closed position in which it closes the cassette hatch 13 y. In the upper and lower housing parts connected at the front, the power transistor 73 and the circuit board 72 are attached to the heat dissipation plate 15 through the mounting frame 74 to the female connector 75 in front of the To arrange plug opening 15 d. While the mounting part 15 c is inserted into the positioning section 6 k in the rear end of the upper housing part 5 , the mounting parts 15 b are pushed into the corresponding recesses 6 a of the upper housing part 5 on both sides of the mounting part 15 c and the mounting parts 15 a are inserted into the recesses 3 b of the lower housing part 2 is used, the heat dissipation plate 15 being attached to the rear ends of the upper housing part 5 and the lower housing part 2. The self-tapping fastening screws 69 a are inserted from the outside into openings (not shown) in the mounting parts 15 a and 15 b and in the bottom openings 6 c of the screw receiving members 3 c and 6 c screwed. At the same time, the self-tapping fastening screw 69 b inserted into the opening 6 d of the upper housing part is screwed into the opening 6 b of the upper housing part 5 like the fastening screws 69 a, so that the front end of the mounting screw 69 b passes the opening 15 e of the mounting part 15 c, as shown in FIG Fig. 34 can be seen. The cap 6 h is inserted into the opening 6 d so that the locking parts 6 e engage in the annular groove 6 j of the cap 6 h and the opening 6 d is closed by the cap 6 h. The upper housing part 5 and the lower housing part 2 are thereby also connected at the rear end and the assembly of the recorder housing 1 is completed. The recorder housing 1 assembled in this way is inserted into the control panel from the rear. The mounting openings formed in the side wall of the control panel and the threaded openings 16 c formed in the mounting plates 16 on both sides of the recorder housing 1 are aligned with one another. The fastening screws (not shown) inserted into the mounting openings from the back of the control panel are screwed into the threaded openings 16 c of the mounting plates 16. Since the pressure pieces 9 c and 4 c of the upper housing part 5 and the lower housing part 2, the play of the mounting plates 16 inwards and to the outside of the recorder case by engaging the mounting plates 16 , the recorder case 1 is fixed firmly and without play to the control panel of the vehicle. When the holder 31 is in the fully assembled recorder case 1 in the recording position, the light shield member 43 is d of the inner frame 42 between the two forked end portions of the photo interrupter 71 on the circuit board 72 which is attached to the heat dissipation plate 15 , as can be seen from FIG . At this time, the detection light beam (not shown) is interrupted and the photo interrupter 71 is turned off. When the holder 31 is moved downward from the recording position and the bottom plate 32 of the holder 31 contacts the bottom plate 43 of the inner frame 42 as shown in Fig. 36, or when the holder 31 is in the insertion / ejection position, as shown in FIG. 37, the light shielding member 43 d of the inner frame 42 is retracted forward from between the two forked end portions of the photo interrupter 71 , with the light path of the detection light beam released and the photo interrupter 71 is switched on. With the aid of the photo interrupter 71 , it is determined that the holder is no longer in the recording position. In contrast, the light shielding member 43 d withdrawn from the light path of the detection light beam returns to the light path of the detection light beam and interrupts it when it comes from the insertion / ejection position holder 31 transported from reaches the recording position, and the photo interrupter 71 is turned off. With the help of the photo interrupter 71, it is determined whether the holder 31 in the recording position befindet.In the assembled pen body 1 is a space inside the housing top part 5 and the lower housing part 2 on the left side of the transport mechanism 41 is provided behind the clock 13 a of the front panel 11 . A motor (not shown) is installed in this space, which supplies the driven gear of the cassette 17 via a gear ratio (not shown) with a driving force for rotating the rotatable plate 19 and via a further gear ratio branching off from the first gear ratio (not shown) the clock 13 a supplies a driving force. These gear ratios (not shown) are also installed in this space. The motor and the gear ratios are installed before the assembly of the upper housing part 5 and the lower housing part 2. The drive gear of the gear transmission (not shown) meshes with the driven gear (not shown), which from outside of the cassette housing 18 by a by placing the with the cassette 17 loaded holder 31 is accessible in the recording position open shutter. The power of the motor 82 is transmitted to the rotatable disk 19 of the cassette 17 loaded in the holder 31 in the recording position through the gear ratio with the drive gear in the upper case 5 and lower case 2 and by the gear ratio with the driven gear in the cassette case 18 Motor, not shown, for operating the clock 13 a rotates forward only at a constant speed over time. With the drive gear and the driven gear meshed with each other (both not shown), the rotatable plate 19 rotates in a direction in which the time scale (not shown) formed on the 7-day registration sheet 21 advances. The clock 13 a moves in one direction, so that the displayed time advances. The operation of the tachograph according to this embodiment in the keyhole 13 of the lock g 13 d utilized key 13 A is rotated beschrieben.Wenn, y in an empty holder 31 in the recording position and the cover 14 closed cassette hatch 13, to the cylinder 13 f to rotate from the normal position to the open / close position, the motor 70 is started to convey the holder 31 from the recording position to the insertion / ejection position. Then, the holder 31 is temporarily moved down from the recording position to to lean on the inner frame 42 . The holder 31 then moves together with the inner frame 42 directly above the base plate 3 of the lower housing part 2 . After a while, the front ends of the guide projections 34 f of the side plates 34 lie on the rear side of the cover 14 , at a location a certain distance from the lower end of the cover 14 rotatably supported by the hinges 3 e, ie at a location on the rear side of the Cover 14 , which is at a radial distance from the axis of rotation of the cover 14 , as can be seen from FIG. 38. By moving the holder 31 further forward, the cover 14 begins to open against the biasing force of the coil spring 3 f. When the holder 31 and the inner frame 42 are moved further forward, the front end of the bottom plate 32 of the holder 31 lies against the rear of the cover 14 a location closer to the lower end of the cover 14 than the location at which the guide projections 34 f abut, as can be seen from FIG. 39. The front end of the bottom plate 32 now pushes the cover 14 open and at the same time the front ends of the guide projections 34 f move away from the rear of the cover 14. When the holder 31 reaches the insertion / ejection position to a certain extent, the bottom plate slides 32 on the rear of the cover 14 and slides from the lower end to the upper end over the rear of the cover 14 until, as can be seen from FIG. 40, the cover 14 is fully opened, whereupon the motor 70 is stopped and the holder 31 is in the insert - / Eject position is stopped. Then, the cassette 17 with the 7-day recording sheet 21 , the circumferential position of which is aligned with the actual time, placed on the rotatable plate 19 and inserted into the holder 31 until the locking projections 18 n over the locking part 37 b of the spring plate member 37 and lock it to fully load the cassette 17 into the holder 31 . The cassette 17 is then temporarily pushed into the holder again until it can no longer be used. Thereby, the motor 70 is started, causing the holder 31 should be transported from the insertion / ejection position to the recording position wird.Wenn when loading the cartridge 17 into the holder 31, the recording sheet containing 18 b to the base plate 32 directed towards, ie, the cassette 17 is inserted upside down, or if the cassette 17 should be inserted with its rear side first, ie the cassette 17 is twisted in the longitudinal direction, the front upper corners and the rear lower corners of the cassette housing 18 interfere with the inclined surfaces 34 a of the holder 31 because they have no inclined surfaces 18 t, thereby avoiding that the cartridge 17 is incorrectly inserted into the holder 31. Since the front parts of the side plates 34 including the guide projections 34 f are formed such that the distance between them towards the front progressively increases, the cassette 17 can be reliably guided through the front parts of the side plates 34 are inserted into the holder 31 , although the lateral position of the cassette 17 when inserting the cassette 17 into the holder 31 differs somewhat with respect to the holder 31. Similar to this, because the guide plates 35 b and 36 b of the right and left holding plates 35 and 36 of the Base plate 32 are inclined, so that the distance between the guide plates 35 b and 36 b from the base plate 32 increases progressively towards the front, the cassette 17 can be reliably guided by these holding plates 35 b and 36 b inserted into the holder 31 , although the vertical position of the cassette 17 with respect to the holder 31 deviates slightly when the cassette 17 is inserted into the holder 31. With the actuation of the motor 70 , the holder 31 loaded with the cassette 17 starts to move from the insertion / ejection position to the recording position. In the initial stage of this transport, the force of the coil spring 3 f causes the cover 14 , the back of which touches the front end of the bottom plate 32 , to begin to close when, as a result of the rearward movement of the holder 31 and the inner frame 42 along and directly over the Bottom plate 3 of the lower housing part 2 pulls the front end of the bottom plate 32 backwards from the front end of the bottom plate 3 of the lower housing part 2. When the holder 31 and the inner frame 42 move further backwards, so that the front end of the bottom plate 32 corresponds to the rear end of the bottom plate 3 of the lower housing part 2 comes closer than its front end, the front end of the bottom plate 32 moves away from the rear side of the cover 14 , which then contacts the lower end of the rear surface of the cassette 17 , as can be seen from FIG . When the holder 31 and the inner frame 42 further move backward causes the coiled spring 3f that the cover closes 14, wherein the rear side thereof in contact with the lower end of the rear surface of the cartridge 17 is bleibt.Wenn the holder 31 as well as the Move the inner frame 42 further backwards and reach a location directly below the recording position, the cover 14 closes the cassette hatch 13 y completely and the cover 14 rests against the stopper (not shown) provided on the inner edge of the cassette hatch 13 y, which prevents further closing of the cassette hatch 13 y. Therefore, the lower end of the rear surface of the cassette 17 is separated from the back of the cover 14 when the holder reaches the position directly below the recording position. The holder 31 , which is prevented from further backward movement at a location directly below the recording position, is now through the further backward movement of the inner frame 42 moves upwards and reaches the recording position in which the motor 70 stops, the holder 31 is stopped in the recording position and the rearward movement of the inner frame 42 is stopped. When the holder 31 has arrived at the recording position, pushes the positioning pin 47 e extending downward from the base plate 47 of the outer frame 46 into the positioning projection 19 b formed on the mounting axis 19 a of the cassette 17 , around the 7-day recording sheet 21 on the cassette 17 with respect to the recording mechanism (not shown) align, the Au fzeichnungsnadel (not shown) of the recording mechanism of the uppermost recording disk 21 a berührt.Dann begins to rotate, the 7-day registration sheet 21 together with the rotatable plate 19 in the cartridge 17, thereby allowing the recording needle of the recording mechanism (not shown) the vehicle operating information successively from the uppermost recording disk 21 a to the next records.Da the base plate 35 a of the left holding plate 35 , which is an area of the uppermost recording disk 21 a of the 7-day recording sheet 21 , in the direction of rotation of the rotatable plate 19 directly to the cutting tool 18 c downstream faces, and a height from the bottom plate 32 of the cartridge 17 has corresponding distance and extending parallel to the bottom plate 32, the base plate 35 a during the recording of vehicle operation information on each registration plate 21 a of the 7-day recording sheet 21 directly above the area of the registration c Heibe 21 a is arranged, which is arranged immediately downstream of the cutting tool 18 c. Similar to this because the base plate 36 a of the right holding plate 36 , which is an area of the uppermost recording disk 21 a of the 7-day recording sheet 21 near the right end of the cassette housing 18 , in the direction of rotation of the rotatable plate 19 is directly upstream of the cutting tool 18 c, facing and has a distance from the base plate 32 corresponding to the height of the cassette 17 and extends parallel to the base plate 32 , the base plate 36 a is on during the recording of the vehicle operating information each recording disk 21 a of the 7-day recording sheet 21 directly above a region of the recording disc 21a near the right end of the cassette case 18 angeordnet.Deswegen maintain the base plates 35 a and 36 a of the right and left holding plates 35 and 36, the recording disks 21 a to down on the cardboard support 21 e when the from the cardboard support 21 e through Cutting through the connecting tape 21 j with the cutting body 18 e separated recording disks 21 a of the 7-day recording sheet 21 are rotated and begin to slide. This reliably prevents the incision 21 c of the recording disk 21 a from getting caught and damaged at the edge area of the holding plates 35 and 36 facing the recording disks. After the vehicle has stopped operating and the vehicle operating information has been recorded on the 7-day recording sheet 21 the key 13 A inserted in the keyhole 13 g of the lock 13 d is rotated to rotate the cylinder 13 f from the normal position to the open / close position. Then, operating the motor 70 causes the holder 31 to move from the recording position is moved downward and the registration disc 21a, which the recording needle of the recording mechanism (not shown) contacted, is separated from the recording needle. Thereafter, the lower end of the rear surface of the cartridge is 17 at a location above the lower end of the back side of the rotatably supported by the hinges 3 e cover 14 to when the directly below the recording position arranged on the inner frame 42 holder 31 together with the inner frame 42 forward bewegt.Wenn the holder 31 and the inner frame 42 move further forward is located at the front end of the bottom plate 32 at the lower end of the back of the cover 14, which begins to open straight and the lower end of the rear surface of the cartridge 17 moves away from the back of the cover 14 . Thereafter, as in the case of the empty holder, the cover 14 continues to open until the holder 31 reaches the insertion / ejection position. When the holder 31 loaded with the cassette 17 and transported from the recording position reaches the insertion / ejection position, the motor 70 stops to stop the holder 31 at the insertion / ejection position. The cassette 17 is removed from the holder 31 that remains in the insertion / ejection position. The escape plate 36 c of the right holding plate 36 , which is an area of the recording disk 21 a of the 7-day recording sheet 21 , in the direction of rotation of the rotatable plate 19 of the cutting tool 18 c immediately downstream, facing, is inclined, so that the distance between the avoidance plate 36 c and the bottom plate 32 to the holding plate 35 increases progressively. When the cassette 17 is pulled out of the holder 31 in the insertion / ejection position, the avoidance plate 36 c extends essentially parallel to the cutting body 18 e in the cassette 17 loaded in the holder 31. Similarly, the outer edge plate 36 d of the right holding plate 36 , which is located at a location passed by a region of the recording disk, in the direction of rotation of the rotatable plate 19 directly in front of the cutting tool 18 c, has a height above the base plate 32 which is equal to the height of the evasion plate 36 c directly in front of the holding plate 35 The above construction offers the following advantage when pulling out the cassette 17 from the holder 31 in the insertion / ejection position. When the connecting band 21 j which adheres 21e on the supporting board, 18 e is separated from the cutting body and the edge region of the recess 21 c to the stop member 18 f is applied, the recording disk described above is 21 a separated from the unrecorded recording disks 21 a and rotates no longer. When pulling out the cartridge 17 from the holder 31 in the insertion / ejection position in the above-described state of the part of the recording disk 21 described touches a, c in the direction of rotation of the rotating plate 19 before the groove 21, which 18e is slipped over the cutting body, not the retaining plate 36 . This avoids that the registration plate 21 described a being caught in the retaining plate 36 and wird.Nachdem damaged during extraction of the cartridge 17, the cartridge 17 is completely pulled out from the holder 31 in the insertion / ejection position, the g in the keyhole 13 of the Lock 13 d inserted key 13 A rotated to rotate the cylinder 13 f from the normal position to the open / close position. This closes the cover 14 and transports the empty holder 31 from the insertion / ejection position to the recording position. When the cassette 17 is inserted into the holder 31 until just before the position where the holding force of the holder 31 begins to act the holder 31 is not transported to the recording position even if the cylinder 13 f is turned from the normal position to the open / close position by the key 13 A inserted in the keyhole 13 g of the lock 13 d. Therefore, it cannot be fully loaded holder 31 cannot be transported from the insertion / ejection position to the recording position, except by fully loading the cassette 17 into the holder 31 and then further pushing it into the holder 31. In the tachograph according to this embodiment, when the setting button 13 c is pressed the time of the clock 13 a is put forward while the holder is in the insertion / ejection position s as long as the set button is pressed regardless of whether the holder 31 is loaded with the cassette 17 or not. The time of the clock 13 a is also advanced when the empty holder 31 is in the recording position as long as the setting button 13 c is pressed. When the holder 31 loaded with the cassette 17 is in the recording position and the vehicle is moving pressing the setting knob 13 c ignored and the time of the clock 13 a not vorgestellt.Wenn loaded with the cartridge 17 holder 31 is in the recording position and the vehicle is stopped, pressing the setting button 13, that the holder 31 from the recording position in the insertion / ejection position is forcibly conveyed. When the holder 31 reaches the insertion / ejection position, the setting button 13 c of the clock can be operated and the time of the clock 13 a is advanced as long as the setting button 13 c is pressed. When transporting the holder 31 from the insertion / ejection position to the recording position, the time t1 elapsed from the start of the motor 70 exceeds the predetermined time T before the holder 31 reaches the recording position, for example, when the holder 31 is caught on the way or the motor 70 is overloaded, the motor 70 is temporarily stopped. Then For example, the direction of rotation of the motor 70 is reversed, that is, the motor rotates in reverse to move the holder 31 to the insertion / ejection position. If since the start of the reverse rotation of the engine 70 elapsed time t3, the predetermined time T exceeds before the retainer 31 reaches the insertion / ejection position or when the engine is overloaded 70, the motor 70 is temporarily stopped, and then again its direction of rotation reversed, ie that the motor turns forward. The reversal of the direction of rotation of the motor 70 is repeated a total of 4 times. If the motor 70 is rotated forward for the third time (including the first forward rotation) and the time t1 since the start of the last forward rotation of the motor 70 still exceeds the predetermined time T before the holder 31 reaches the recording position or if the motor is overloaded, the The motor 70 stops and the indicator lamp lights to indicate that there is an abnormality. When the holder 31 is transported from the recording position to the insertion / ejection position, the time t3 since the start of the reverse rotation of the motor 70 exceeds the predetermined time T before the holder 31 reaches the insertion / ejection position, for example if the holder 31 gets caught on the way or the motor 70 is overloaded, the motor 70 is temporarily stopped. Then the direction of rotation of the motor 70 is reversed, i.e. the motor rotates forward around the holder 31 to be transported to the recording position. When the elapsed time t1 from the start of the forward rotation of the motor 70 exceeds the predetermined time T before the holder 31 reaches the recording position or when the motor 70 is overloaded, the motor 70 is temporarily stopped and then reversed again, that is, the motor The reversal of the direction of rotation of the motor 70 is repeated a total of 4 times. When the motor 70 is rotated in reverse for the third time (including the first reverse rotation) and the time t3 since the start of the last reverse rotation of the motor 70 still exceeds the predetermined time T before the holder 31 reaches the insertion / ejection position or when the motor is overloaded , the motor 70 is stopped and the indicator lamp lights up to indicate that there is an abnormality. This reverse operation of the motor 70 in connection with an abnormality during the transferring of the holder 31 from the recording position to the inserting / discharging position is also during the forced transport of the holder 31 running from the recording position in the insertion / ejection position, which c is activated by pressing the setting button 13 when loaded with the cartridge 17 holder 31 in the recording position by a befindet.Bei during transport between the insertion / Ejection position and the recording position When the anomaly has occurred, the indicator lamp 13 x turns on, the direction of rotation of the motor 70 is reversed to transport the holder 31 to the insertion / ejection position when the cylinder 13 f is rotated from the normal position to the open / close position by means of the key 13 A. If the elapsed time t3 from the start of the reverse rotation of the motor 70 exceeds the predetermined time T before the holder 31 reaches the insertion / ejection position, e.g. For example, by entanglement of the holder 31 on the road or by an overload of the motor 70, the motor 70 is temporarily stopped, and reversing the direction of rotation of the motor 70 is up to 4 times wiederholt.Wenn elapsed since the start of the reverse rotation of the motor 70 Time t3 nevertheless exceeds the predetermined time T before the holder 31 reaches the insertion / ejection position or the motor 70 is overloaded, the motor 70 is stopped and the indicator lamp 13 x lights up to indicate again that there is an abnormality. In the above described tachograph according to this embodiment is the cassette hatch 13 y - which is formed in the front plate 13 of the front panel 11 and represents the front surface of the recorder housing 1 and which the holder 31 passes when it moves between the insertion / ejection position outside the recorder housing 1 and the Recording position is transported inside - designed so that it has the lower portion the front panel 13 opens and is opened and closed by the cover 14 in connection with the transport of the holder 31 . The upper housing part 5 and the lower housing part 2 are stacked behind the front panel 11 . The bottom plate 3 of the lower housing part 2 - which represents the lower surface of the recorder housing 1 - is arranged such that the front end of the bottom plate 3 adjoins the lower end of the front plate 13 in which the cassette hatch 13 y is formed. At the front end of the bottom plate 3 , the hinges 3 e are provided which rotatably support the lower end of the cover 14. Compared with the construction in which the cover 14 is rotatably attached by hinges on the front plate 13 of the front panel 11 , it is with this one Construction does not require the front panel 13 to be extended downward from the cassette hatch 13 y to provide a reinforcement area for the hinges or to extend the front panel 13 rearward at the lower end so that the extended panel area faces the ceiling panel 12 . Therefore, it is possible enlarging the vertical height of the front plate 13 or the front panel 11 to prevent the whole, which of casting caused by the in the plate portion, which extends from the lower end of the front plate 13 to the rear, formed Gußschräge wird.Die bottom plate 3 , to which the cover 14 is rotatably attached by the hinges 3 e, has a certain degree of strength, because the hinges 3 e extend to the rear end of the recorder housing 1 with the side plates 4 . Therefore, the bottom plate 3 reinforces the hinges 3 e without providing a structure for reinforcing the hinges 3 e, which increases the vertical height of the recorder housing 1 as a whole. It is possible to omit the construction in which the guide projections 34 f, which at a location above the lower end of the cover 14 rotatably supported by the hinges 3 e abut at the rear thereof, are provided at the front ends of the side plates 34 of the holder 31. However, the structure in which the guide protrusions 34 f at the front ends the side plate 34 are provided, as in this embodiment, the following advantages. When opening the cover 14 closing the cassette hatch 13 y by pressing the holder 31 from the rear, a greater torque is exerted on the cover 14 than if the front end of the bottom plate 32 of the holder 31 the cover 14 at a location near the hinges 3 e , or the lower end of the cover 14 . When the cover 14 is opened, the holder 31 exerts a lower force on the cover 14 . Thereby, the reaction force on the hinges 3 e exerted is lower, whereby the required thickness of the hinges 3 can be reduced e kann.Deswegen it is not necessary to provide an extended structure 3 e for amplifying the hinges and it can be avoided that the vertical height the bottom plate 3 of the lower housing part 2 rises, which helps to minimize the vertical height of the recorder housing 1 as a whole. In this embodiment, a case has been described in which the cover is biased by the spiral spring 3 f in the closing direction. It is also possible to choose a construction in which the closed cover 14 which has closed the cassette hatch 13 y is locked by a hook (not shown) which is provided on the edge of the cassette hatch 13 y and which is unlocked when the cover 14 is pressed on from the rear by the guide projections 34 f of the holder 31 to enable the cover 14 to open by its own weight. In this case, the cover 14 can be connected to the holder 31 , for example by a cord, be connected so that when the holder 31 is transported from the insertion / ejection position to the recording position, the cover 14 is closed by means of the cord drawn from the holder 31. This invention can also be applied to the tachograph which the cover 14 not pretensioned with the spiral spring 3 f. This embodiment of the invention has been described in an example in which the tachograph controls the driving records information on the 7-day registration sheet 21 . The invention can also be applied to a tachograph which records the driving information on a 1-day record sheet. Although this embodiment describes a tachograph in which a cassette 17 with the 7-day record sheet therein is removably inserted into the holder 31 , The invention can also be applied to the so-called shop trip recorder, according to the prior art, which has been proposed by the applicant in the past, in which a drawer with a rotatable plate is transported into or out of the recorder housing.
