ABSTRACT:
A manually rotatable film wind thumbwheel for a camera comprising a peripheral series of interdental spaces having a uniform pitch, is characterized in that a continuous series of finger-receiving indentations is located adjacent the peripheral series of interdental spaces and has a uniform pitch which is greater than the uniform pitch of the interdental spaces to permit the finger-receiving indentations to be more easily fingered than the interdental spaces to manually rotate the thumbwheel, whereby the interdental spaces can be used as locking spaces which individually receive a film metering pawl of the camera to arrest the thumbwheel and/or an anti-backup pawl to prevent counter-rotation of the thumbwheel.
