Logic-controlled card recorder base

The utility model relates to a transformation mechanism of the power transmission and the work modality of a logic control card recorder base, which belongs to the technical field of magnetic tape drive devices. The utility model is characterized in that a single motor can be used as the power of the high and low speed tape coiling and the work modality transformation of a cassette; partial-tooth cam components can be controlled by electromagnetic solenoids, and thereby, the work modality can be controlled by the partial-tooth cam components; the work modality of stop, search, quick tape coiling, playback, etc. can be formed. The utility model formed by the components has the advantages of simple structure, convenient operation and exact action, and can effectively reduce parts and production cost.
