Definitions

• the invention relates to a tachograph with a housing in which a particular printing head having a printing device and a receiving chamber for a roll of printable by the printing device ribbon-like printing material is arranged, wherein the receiving chamber a loading opening and the housing directed to an operator side of the housing Has housing opening and the housing opening is closed by an openable lid, with one or more arranged on the lid controls a locking unit, by the de- disgusting in its closed position and can be moved against a spring force from a locking position to an unlocking position.
• the operating element is actuated counter to a spring force and unlocks the locking unit, so that the lid can be opened to insert a new roll of printing material in the receiving chamber. Thereafter, the lid is closed again, wherein the spring force holds the operating element and thus the locking unit in its locking position.
• the object of the invention is to provide a tachograph of the type mentioned, the lid by means of a simply constructed locking unit is securely locked in its closed position.
• a pivotally mounted in or parallel to the plane of the lid horizontally extending pivotally mounted between the locking position and the unlocking pivot shaft has a radially directed locking arm having a latching hook at a radial distance to the pivot shaft through which a housing-fixed locking projection is engaged behind and with at least one radially directed pivot lever of the pivot shaft, which is in a radial distance to the pivot shaft of the control against a spring force the latch hook out of engagement from the locking projection bringing pivotally acted upon.
• This design is simple, wherein the locking unit can be unlocked by a manual pivoting movement of the pivot shaft and the pivot lever and is kept securely locked in the locking position.
• the lid may be a closure flap which is pivotally mounted on the housing about a lid axis extending along an edge of the closure flap, wherein the pivot shaft is pivotally mounted on the closure flap.
• a particularly good accessibility for equipping the receiving chamber with a new roll of printing material is achieved in that the lid is arranged on the operator-side end of a drawer-like carrier having the receiving chamber, which on the operator side protrudes from a receiving device. Shaft of the housing is moved out, wherein the pivot shaft is pivotally mounted on the carrier or the lid.
• the lid and the carrier by the locking unit despite high shock loads during operation of the vehicle and thus due to the high mass acceleration of the lid and carrier is held securely locked in its closed position.
• the latching hook and / or the latching projection may have a ramp rising in the direction of movement of the carrier, on which the latching hook and / or the latching projection in the case of an insertion movement the carrier along the latching arm from its locking position in its unlocked position along.
• the latching hook After reaching the inserted end position of the carrier, the latching hook then rams the catch projection into its locking position.
• both latching hooks and latching lugs have ramps, these are preferably rising in opposite directions to one another.
• Component and space saving is when the locking projection is formed in a side wall of the housing, wherein preferably in both side walls latching lugs are formed, which are engaged in each case by a latching hook.
• the pivot shaft and / or the locking arm may be spring-loaded in the locking position.
• the latching hook when retracting the carrier in the receiving shaft and its correct position for latching, preferably the pivoting of the pivot shaft and / or the locking arm is limited in the locking position by a carrier-fixed stop.
• Such a component is easy to produce when latching arm and / or spring arms and / or pivot shaft are formed as a plastic injection-molded part.
• the operating element can be displaceably guided in a continuous opening of the cover facing the operator side, and the pivot lever can be acted on at a radial distance from the pivot axis by the end region of the operating element facing away from the operator side.
• the operating element can be easily mounted, a cylinder-like control knob.
• the operating element is preferably acted upon on its side facing away from the operator side by a pretensioned compression spring supported on the carrier, in particular a helical compression spring until abutting against a stop in the operator direction.
• a pretensioned compression spring supported on the carrier in particular a helical compression spring until abutting against a stop in the operator direction.

• the tachograph shown in the figures has a housing 1 with a rectangular cross-section in DIN radio format and can be used in a corresponding shaft in a dashboard of a motor vehicle.
• the housing 1 On its operator side, the housing 1 has a diaphragm frame 2 with a housing opening 3, which can be closed by a cover 5. Below the housing opening 3, an insertion slot 4 is formed in the diaphragm frame 2, in which a smart card is inserted, the memory chips for storing data such as driver, vehicle, ride and working data contains.
• a control knob 6 is arranged, which is part of a locking unit, by which the lid is locked in its illustrated closed position.
• the cover 5 is arranged on a drawer-like support 7, which is moved out to the operator side out of a receiving shaft 8 of the housing 1.
• the carrier 7 has two mutually opposite side walls, with which it is guided on side walls 9 of the receiving shaft 8 slidably.
• the carrier 7 In the extension direction 11, the carrier 7 is acted upon by a compression spring (not shown).
• a receiving chamber 10 of the carrier is accessible from the outside, in which a roll of ribbon-like printing material is used, by a not shown, also on the carrier 7 arranged printing device with driver, vehicle, and driving Working time data is printable.
• the free end of the roll of the printing material can be guided through a printing material slot 11 in the upper edge region of the lid 5 to the outside.
• a groove 12 which is open toward the operator side is formed on the front side of the carrier 7, which groove has a bottom formed as a rounding.
• a pivot shaft 13 is rotatably mounted in the closed to the operator side by the lid 5 groove 12.
• plastic components 14 are rotatably disposed, which have a radially directed latching arm 15 which projects into a recess open to the operator side of the side wall 9 of the housing 1.
