<p>PURPOSE:To provide a program changing mechanism capable of executing a program change and simplifying its structure by utilizing the movement of a head plate for moving a head and the reversal rotation of a driving mechanism. CONSTITUTION:A change idler mechanism 61 is operated by moving the head plate 2 and rotating the driving mechanism 60, and a changing plate 23 is moved so that a changeover operation of one pinch roller 17F and a power transmission to one tape take-up reel 8F are controlled by moving this changing plate 23. Then, flywheels 27F and 27R are reversely rotated by the driving mechanism 60 to operate the change idler mechanism 61 in the reverse direction, thus the changing plate 23 is reversely moved to control a changeover operation of the other pinch roller 17R and the power transmission to the other take-up reel 8R, and hence a program change is executed.</p> |
