ABSTRACT:
An arrangement for controlling the advance of a magazine in a transparency projector in which a fork advancing the magazine, is subjected to the action of a return spring having one end constantly fixed to a control member which is pivotally mounted about a fixed axis. An operating member having a cam-shaped portion cooperates with the control member so that the advance of the operating member towards the fork initially pivots the control member due to the action of the cam-shaped portion. The fork becomes thereby pivoted by the return spring until the extreme position is reached, in which the fork is locked against the magazine. When the operating member is withdrawn, the fork is released from engagement with the magazine.
