Japanese Patent JP3194690
PROBLEM TO BE SOLVED: To obtain a tachograph apparatus which achieves a saving of space with the miniaturization of a recorder while improving the freedom of a mounting position by separating a speed detecting section from the recorder.
SOLUTION: A transmission gear 10 has a speed sensor added thereto and a worm gear 14 mounted at one end of a flexible cable 13 is meshed with a worm 12 of an output shaft 11. The other end of the cable 13 is connected to a distributor 16, which distributes the rotational speed with the action of a gear provided inside and outputs the results through flexible cables 18, 19 and 61. A recorder M records a speed transmitted through the flexible cable 19 on a recording paper 54 and a speed meter S swings a speed pointer 32 corresponding to the speed transmitted through the flexible cable 18. A speed detector 62 detects the speed at an interval of a plurality of stages and supplies an electrical signal obtained to a speed indicator SI through a harness 63 to light a display means 34 visibly.
