A magnetic recording/reproducing apparatus having an opening and closing door for loading and unloading a magnetic sheet pack, the door being adapted to override a position wherein the door is locked and then to return thereto, upon loading the magnetic sheet pack. The door has a pressure member which, during the overriding movement of the door, presses a center core of the magnetic sheet to forcibly mount the magnetic sheet onto a spindle. The pressure member is spaced from the center core when the door retreats to its locked position, in which the door cannot move in any direction. A switching member is provided so as to control a driving motor for the spindle in cooperation with the action of a mechanical device for locking the door.

This disclosure depicts a feed device for a magnetic head applicable to an electronic still camera or a reproducer in an electronic camera system wherein a subject is pure-electronically still-photographed and recorded in a rotating magnetic disc, and the reproducing of an image is carried out by a television system or a printer. The feed device for a magnetic head utilizes a planetary gear reduction mechanism to obtain a high reduction ratio, whereby a head carriage carrying the magnetic head is finely fed. The planetary gear reduction mechanism comprises: a sun gear connected to a rotary driving source; a stationary internal gear wheel disposed concentrically with the sun gear therearound; a rotary internal gear wheel for the output disposed concentrically with the stationary internal gear wheel; at least one first planetary gear being in mesh with the stationary internal gear wheel as well as the sun gear; at least one second planetary gear being in mesh with the rotary internal gear wheel as well as the sun gear; and an arm member for rotatably supporting said first and second planetary gears so that the planetary gears can revolve respectively around the sun gear. The rotary internal gear wheel for the output is connected to the head carriage carrying the magnetic head through the rotation-linear movement converting mechanism and performs the fine feed of the magnetic head, e.g. by 100 .mu.m with high accuracy.
