Abstract: A printer is disclosed having a media unit which can move relative to a printing unit. Until now, difficulties in aligning the media unit in the printer always resulted in a poor printing quality. To rectify this, the disclosed printer provides that the printing unit is designed so that it can move inside the housing, and elements are provided for aligning the printing unit with the media unit so that the printing unit and the media unit can be aligned with one another when the media unit is pushed in the direction of insertion. A resilient element enables the printing unit to be advantageously tensioned, in a manner that equalizes tolerances, against the support of the media unit in an operating position. This enables an advantageous equalization of work tolerances and positional tolerances, and the position of the print head relative to the medium to be printed.

Abstract: In a method for transferring data from a tachograph (1) onto a smartcard (3), the smartcard (3) is moved out of and back into the tachograph (1) by an electromotive drive (8) as a function of stipulated conditions. In the process, spring contacts (6) of the tachograph (1) rub over contact areas (5) of the smartcard (3) and remove any dirt which may be present. The conditions for starting the electromotive drive (8) and the intended operation of the electromotive drive (8) are stored in a memory (10) of an electronic control device (9).

Abstract: A chip-card-receiving device has a carriage for holding a chip card, means for fixing and releasing a chip card, and a clamping element. The carriage is displaceably mounted between an insertion/removal position and a reading/writing position on a carrier. The clamping element is spring-mounted on the carriage such that the clamping element rests resiliently on an inserted chip card. The clamping element has ramps formed on the carrier such that the clamping element is lifted from a plane of the chip card in an insertion/removal position of the carriage.

Abstract: A printer with an elongated media output port is disclosed. The printer may be used for a digital tachograph of a motor vehicle. The printer includes at least one bearing surface which limits the media output in the transverse direction and along which the printing medium slides during output. The boundary conditions for the operation of a small-format printer in a digital tachograph of a motor vehicle makes it necessary that the media output port has to be sealed off against the ingress of harmful media. Therefore, the media output port includes an elongate sealing closure which is movable in the transverse direction and presses elastically against the bearing surface by a sealing feed guide. The printing medium is capable of being outputted between the bearing surface and the sealing closure in an output direction.

Abstract: The invention relates to a printer having a paper transporting cylinder and a housing provided with a panel having a paper output slit. The printer also has a device for protecting against the penetration of dust and spray water. According to the invention, the device includes a wedge which, in a first position, closes the paper output slit when the printer is not in use, and, in a second position, opens the paper output slit when the printer is in use in such a way that paper can pass though the paper output slit. The invention also has a drive for displacing the closing wedge from the first position to the second position and back.

Abstract: The invention relates to a chipcard housing having a first and a second central piece, whereby the first central piece can be displaced by a drive. A locking element is also provided by which a displacement of the second central piece is prevented in a first working position and which may be operated by the first central piece such that the locking is released in a second working position. Both central pieces can mutually entrain the other in the second working position by means of a coupling element and the second central piece includes entraining elements for cooperation with a chipcard. The chipcard housing can be very compact and have a high resistance to shock and vibration influences and hence against manipulation.

The second guide element (12) interacts with the first guide element (11) in such a way that the driver (9) is moved towards the contacts (8) when a movement in feed-in direction or opposite the feed-in direction in the direction of separation occurs.

Abstract: The invention relates to a card receiving device (1) provided with the flat design comprising at least one locking element (30r, 301). The invention also relates to a method for receiving a card (2). Particular difficulties arise due to the small installation space, legal rules, the inexactnesses of the cards to be used, the environment that is often dirty, and to the ingenuity of manipulation attempts. The aim of the invention is to fulfill the legal requirements and to ensure a good functioning under adverse operating conditions. To this end, the invention provides that the locking element (30r, 301) has at least one contact surface (39r, 391) that touches the card (2) and presses it, at least occasionally, in the direction of insertion (9). The invention also relates to a corresponding method. The invention effectively combines function and security.
