Film loading apparatus using planet gear

A film loading apparatus using a planet gear comprising:

• a feeding gear for initial film feeding;
• a rewinding gear for rewinding a film;
• a planet gear disposed in such a manner as to move between the position at which said planet gear meshes with said feeding gear and the position at which said planet gear meshes with said rewinding gear by changing the direction of rotation of said planet gear;
• and
• a stopper member provided at the position at which said stopper member checks the movement of said planet gear when said planet gear is disengaged from said feeding gear and sent flying toward said rewinding gear at the time of initial film feeding and at which said stopper member engages said planet gear when said planet gear is reversely rotated and moved toward said rewinding gear.

A film loading apparatus using a planet gear comprising:

• a one-tooth sprocket which engages a perforation of a film for the purpose of initial film feeding;
• a feeding gear integrally provided with said one-tooth sprocket;
• a fork gear which engages the take-up shaft of a film patrone;
• a rewinding gear connected to said fork gear via a gear train;
• a motor for winding said film around a spool for every exposure;
• a sun gear connected to the pinion of said motor via a gear train;
• a planet gear connected to said sun gear in such a manner as to move between the position at which said planet gear meshes with said feeding gear and the position at which said planet gear meshes with said rewinding gear by changing the direction of rotation of said planet gear;
• and
• a stopper member provided at the position at which said stopper member checks the movement of said planet gear when said planet gear is disengaged from said feeding gear and sent flying toward said rewinding gear at the time of initial film feeding and at which said stopper member engages said planet gear when said planet gear is reversely rotated and moved toward said rewinding gear.
