1. Field of the Invention
This invention relates to an improvement in a camera of the kind using a film provided with a magnetic storage part and having a magnetic head arranged in the camera to read information such as ISO data, etc. written in the magnetic storage part of the film and to write therein some information as necessary.
2. Description of the Related Art
Cameras of the kind using a kind of film that has a magnetic storage part have recently been proposed, for example, as disclosed in U.S. Pat. No. 4,864,332. This camera is arranged to record in the magnetic storage part some photographic information such as a shutter time value, an aperture value, a date, a title, etc. and to read the recorded information as necessary out of the magnetic storage part by means of a magnetic head. However, practical attempts for affecting cameras of the kind having this magnetic head have encountered the following problems:
1) Cameras of the kind disclosed in U.S. Pat. No. 4,841,319 etc. are arranged as follows: A film cartridge containing the whole roll of film completely therein including the leader part of the film is used. The film cartridge is inserted into a cartridge chamber, for example, from one side of the camera. The film is then pushed out of the cartridge by driving its shaft with a fork. With the cartridge of the kind used for a film having a magnetic storage part, an automatic film loading operation tends to become impossible, because the writing/reading magnetic head is merely arranged to come into contact with the film surface, the fore end part of the film tends to collide either with the magnetic head or with a film retaining pad and to be bent and warped when it is pushed out from the cartridge.
2) When the camera is carried by the photographer, for example, by hanging on the neck while walking, vibrations are transmitted to the camera. Under such a condition, various accidents tend to happen including that the magnetic storage part of the film might be damaged by the movement of the magnetic head.
