Camera having a magnetic flux shielding device

A camera, comprising:

• a cartridge chamber to load a film cartridge which accommodates a magnetically recordable film;
• a winding spool to wind the film;
• a drive motor provided within said winding spool to drive the winding spool;
• a magnetic information reading device to read the magnetic information recorded on the film;
• an inner shielding member on a same shaft with the rotation shaft of the drive motor;
• and
• an outer shielding member on the same shaft with the rotation shaft of the drive motor,
• wherein the saturated magnetic flux density of the inner shielding member under a high intensity magnetic field is greater than the saturated magnetic flux density of the outer shielding member under the high intensity magnetic filed, and the saturated magnetic flux density of the outer shielding member under a low magnetic field intensity is greater than the saturated magnetic flux density of the inner shielding member under a low magnetic field intensity, and the inner shielding member and the outer shielding member are connected to a ground potential.

A magnetic flux shielding device, suitable for use in a camera, to shield magnetically recordable film from magnetic flux, comprising:

• a winding spool to wind the film;
• a drive motor positioned within the winding spool to drive the winding spool;
• an inner shielding member to shield the film from magnetic flux generated by the drive motor;
• and
• an outer shielding member positioned outside the inner shielding member to shield the film from magnetic flux generated by the drive motor.
