Abstract: A cleaning device for a recording and/or reproducing apparatus including a rotary head device having a drum carrying a magnetic head, with a magnetic tape being used as a recording medium. The cleaning device includes a cleaning member abutted against the magnetic head of the rotary head device for cleaning the magnetic head and an actuating mechanism for causing the cleaning member to be abutted against the magnetic head in the rotating state of the rotary head device. The actuating mechanism causes the cleaning member to be abutted against the magnetic head in the rotating state of the rotary drum prior to the loading of the magnetic tape on the rotary head device by the tape loading mechanism, and releases abutment of the cleaning member against the magnetic head when loading the magnetic tape by the tape loading mechanism on the rotary head device. The magnetic head is cleaned each time the magnetic tape is loaded.

Abstract: A magnetic tape cassette recording and/or reproducing apparatus is provided with a novel loading system which includes a magnetic tape cassette holder movable at least horizontally between an eject position wherein the cassette holder extends from the front face of a housing of the recording and/or reproducing apparatus and a loading position wherein the cassette holder is retracted within the housing and the magnetic tape cassette is in its set position. The cassette holder is cooperative with a cassette actuating means which moves a pivotal front closure lid and a sliding lower cassette face closure member of the magnetic tape cassette between open and closed positions. The cassette actuating means is active during the movement of the cassette holder between the eject position and the loading position to open and close the pivotal closure lid and the sliding closure lid of the magnetic tape cassette.
