Abstract (en)
[origin: EP2372690A1] The drive (1) has an adjustment element e.g. hand drive shaft (24) wing (25) and crown wheel (26), coupled with force-transmitting elements for manual adjustment of a rotary position of a tuning peg (5). The force-transmitting element are designed as three-stage toothed wheels (11-23) and comprises a gear stage on which a drive motor (9) acts with an output shaft, and a last gear stage, which acts on the tuning peg in order to rotate the last gear stage. The adjustment element acts on other gear stages of the wheels between the former and the last gear stages for force guidance. An independent claim is also included for a device for automatically tuning a string of a stringed instrument, comprising a detection unit.
