Claims

[Scope of utility model registration request]

(1) A magnetic tape having multiple tracks on which music of different pitches or formats is synchronously recorded, and a playback circuit provided for each track of this magnetic tape to play back the signals recorded on the corresponding track. and a switching circuit that switches and selects the output of each of these reproducing circuits.

(2) The switching circuit is characterized in that it receives a signal from a switching signal section set at a predetermined position on the tape to perform a switching operation, and the switching signal uses a sensing foil or one that detects a specific frequency signal. A reproduction device according to claim 1 of the utility model registration claim.

(3) As a switching circuit, a variable resistor is installed between the transmission line of each regeneration circuit and the ground, and its resistance value decreases when a control voltage is applied to it, and its resistance value changes depending on the magnitude of this control voltage. The element and the control terminal of the corresponding variable resistance element provided for each variable resistance element are connected to a fade-out circuit that attenuates the signal level with a predetermined time constant, and the control terminal of the corresponding variable resistance element is connected to a fade-out circuit that attenuates the signal level with a predetermined time constant. A playback device according to claim 1 or 2 of the utility model registration claim, characterized in that the playback device includes a changeover switch that connects a control terminal to a fade-in circuit that increases the signal level at a predetermined time constant. .
