Aaton Magazine
48
3.1 Concept
The Penelope magazine is designed to be quickly installed or removed, and
to be loaded easily, it handles up to 400ft (122m) loads of 35mm film stock.
The magazine sprockets are driven through a magnetic clutch by a motor
located in the camera body itself. This system reduces noise and power
consumption, and prevents mechanical abuse in case of misloading.
The feed roll footage can be checked through a mechanical footage counter
located on the magazine door. The remaining or elapsed footage also
appears on the camera control panels, see Chapter 1.
3.2 Pressure plate system
Claw rear pressure plate
This plate (A) is located at the front of the magazine. When the loaded mag-
azine is installed on the camera body, its main function is to hold the film as
the claw engages the film perforations. Proper positioning of this element is
essential to steadiness and quietness of operation.
Picture rear pressure plate
The striped pressure plate (B), positioned at the camera’s picture taking gate
level, holds the film in the right back focus position.
