(CI. 88-17) The present invention relates to a guide mem ber for motion picture apparatus of the maga zine type and more particularly to a guide mem ing II! which contains a cover plate it which has ber which compels tilting of the ?lm magazine 5 \during insertion into or removal from the maga zine chamber of said apparatus. Such a guide member is disclosedbut not claimed in my co pending application, ‘Serial No. 1372, filed Janu ary 11, 1935, for mprovements in an Ejector for carries a latching bar It which can be operated by a button [5 on the exterior of cae ing I 0 and which carries a saddle piece 58 for Operating the closure means on the ?lm mage~ zine.

Other and further ob iect's of the invention will be suggested to those skilled in the art by the disclosure which follows. 25 The above and other objects of the invention are obtained by merely providing a guide or spring member which extends into an open sided magazine chamber of a motion picture apparatus, ber 20. A ?lm advancing mechanism is located within casing _l 0 and includes a driving eccentric 24, a claw arm 25 pivotally connected to said driving‘ 26 into the magazine chamber. The ?lm magazine, see Fig. 2, comprises 2 cas said guide or spring member overlying or over- I ing with a side wall 29 and an edge wall 29 ex tending around the edge of wall 28. An auxiliary wall 30 is attached to edge wall 28 and extends ' along the front and upper portions thereof, being after insertion. spaced a slight distance from edge wall 29. A Reference is hereby made to the accompanying ?exible shutter 3i is slidable between edge wall 35 edrawing wherein similar reference characters 29 and auxiliary wall 39, being operated by a pin 32 which extends through a slot 33 in the upper designate similar elements and wherein: portion of edge wall 29 and which fits into the Fig. 1 is a side elevation of a motion picture piece [6 on the latching bar M.
