ABSTRACT:
The present invention relates to a mechanism for solving problems involved in miniaturizing a disk driving apparatus. A pin provided on a latch lever for latching a cassette guide has a movement restricting part on its top to prevent the pin and a stopper from disengaging from each other in a direction perpendicular to the direction of disk insertion. When a cassette is placed in an ejected state wherein the amount of projection of the cassette from a panel is approximately the same as the amount of projection of a push button from the panel, a recess formed in the pin and the stopper engage with each other so that the cassette can be reliably ejected. Further, the cassette guide has, on opposite sides thereof, inserting guides for guiding insertion of the cassette, and a portion corresponding to a movement path portion for a head is eliminated from the cassette guide to form a space which serves as a movement path space for the head. The inserting guide of the cassette guide, which is positioned on a side on which the space is formed, has a projection on its rearmost end portion so that the cassette can be supported on the projection.
