<p>PURPOSE:To simplify the constitution on the mechanism and electric circuit in the system providing only one erasing head, by changing over the height of magnetic head with the reversing operation and providing the change-over plate having the latch section in latching with the member relating to the recording operation. CONSTITUTION:In the recording change-over mechanism for tape recorders, possible for the reversing opration of magnetic tape such as automatic reversing, the magnetic head adjusting mechanism on the slide base plate 1 can change the height of the magnetic head 18 with the rotating operation of the operating arm 11 by taking the support shaft 20 as a fulcrum, and th switch 52 is changed over according to the lift up and down operation of the magnetic head 18 and the channels are changed over with circuits. During recording, since the pin 48D of the recording operation lever 48 is latched with the concave 37E of the change-over plate 37, the movement of the change-over plate 37 is blocked toward the arrow F, and when not under recording, the latch between the pin 48D and the concave 37E is released, allowing to enable the reversing operation of magnetic tape.</p> |
