Problems solved by technology

[0003] However, the known tachograph and the known paper roll have the disadvantage that deviations may occur between the printing device and the visible grid of the area to be printed on the paper roll, so that the alignment of the data with respect to the visible grid cannot be reliably ensured. Location
The cause of this deviation may lie in the components of the tachograph itself, for example deviations caused by fluctuations in the diameter of the toothed rollers or fluctuations in the position of the printing unit
In addition, deviations may be caused by fluctuations in paper geometry or by visually visible grid geometry fluctuations
In addition, this deviation can also be caused by the hygroscopicity of the paper tape of the paper roll when the tachograph is in operation

Embodiment Construction

[0024] FIG. 1 schematically shows a longitudinal section through a tachograph 1 for a motor vehicle, the tachograph having a front panel 2 . The tachograph 1 has a store 3 with a paper roll 4 and an electric drive 5 for transporting a paper tape 6 wound on the paper roll 4 . Furthermore, tachograph 1 has a printing device 7 for printing a paper strip 6 of a paper roll 4 . To simplify the illustration, the printing unit 7 is only shown in the form of a printing roller. The paper tape 6 of the paper roll 4 comes out from the storage part 3 , and is transported to the gap 9 of the front panel 2 through the printing device 7 in the paper guide device 8 . The paper strip 6 printed by the printing unit 7 is output through the slot 9 in the front panel 2 and can be torn off. Furthermore, two sensors 10 , 11 are arranged on the paper guide 8 for detecting the position of the paper web 6 in the paper guide 8 . The two sensors 10 , 11 , the motorized drive 5 and the printing unit 7 a...

Abstract

The present invention relates to a trip recorder used for the motor vehicle, which has a storage part (3) used for scroll (4), and a plurality of sensors (10, 11) used for determining the longitudinal direction of the paper tape (6) in the scroll (4) and movement of the paper tape. The sensors (10, 11) are connected with the controlling devices, and the controlling devices control the printing device according to the location and the status of the paper tape and control the driving device (5) used for driving paper tape. Thus, the printing device (7) can aim at the pre-printing area (13) set on the paper tape (6).

Description

technical field [0001] The invention relates to a tachograph for a motor vehicle, the tachograph having: a paper roll storage; The tape is wound on the paper roll; the drive unit is used to drive the paper tape of the paper roll; the electronic control unit is used to control the printing unit and the drive unit. Furthermore, the invention also relates to a paper roll for a tachograph of this type, having: an area to be printed arranged on a wound paper strip; a visible grid on the area to be printed. Background technique [0002] The known recording devices generally have toothed rollers, the spikes of which engage in the edge perforations of the paper strip and ensure the feeding of the paper strip of the paper roll below the printing device. And the edge perforation of the paper tape is used to align the printing device with the area to be printed with the grid and to reduce slack when driving the paper tape. When a new paper roll is inserted, the printing unit is calib...
