"abstract": "“The Cinema at Home””it was with this forceful announcement that Pathé-Cinéma put on the market in 1922 a projector which was made rather like a handbag, light, portable and looking something like a toy.1 Films of 9.5mm width could be projected with it at home on a small screen. It was very easy to manipulate, even for children. Safety film (then called “non-Ham”) was used. The width of the film was 9.5mm, and the perforations were placed in the middle of the film between the frames. It was supplied in 8.50-meter lengths on small reels or in cassettes, and gave several minutes of projection time. After projection, the film was rewound in its cassette (Fig. 1).",
