<p>PURPOSE:To close a power supply switch simultaneously when a pinch roller is press-contacted to a capstan, by displacing a pinch roller operating lever interlockingly when a mechanism constituent is completely pushed into a device main body. CONSTITUTION:With a moving frame 10 of a mechanism constituent 2 slid in this side direction, when a cassette 35 is loaded, a detection piece 41a is pushed at the rear part of the cassette 35 and a detection lever 41 is slightly slide and a projection 48b of an operating lever 48 and a latch piece 41 of the lever 41 are unlatched. When the mechanism constituent 2 is pushed into a device main body from the above state, after the restriction of a control pin 49 is released, a pinch lever 44 is turned clockwise by a spring 68 together with the operating lever 48 and a pinch roller 46 is press contacted to a capstan 32.
