US 5,963,747 A · Photographic recording or reproducing device and film cartridge having movable sealing member for sealing film entrance opening thereof

Abstract

The invention relates to a photographic recording or reproducing device, preferably a camera, with a transportation device for the frame-by-frame transportation of a film along a film transportation path and with a film measuring device with an engagement member rotatable about an axis for engaging in perforation holes of a peripheral perforation of the film, the film transportation device being locked when the film reaches a position during its transportation which is provided for the recording or reproduction of an image, and the engagement member comprising an advancing engagement element in relation to its rotational movement and a trailing support element and being adjustable transversely to the film transportation path as a function of the abutment of the support element upon a surface extending parallel to the film transportation path. In addition, the photographic recording or reproducing device includes a transportation device for the frame-by-frame transportation of a film along a film transportation path and a film measuring device with a rotatably and displaceably mounted engagement member for engaging in a peripheral perforation of a film, the film transportation device being locked by a locking device when the film reaches a position during its transportation which is provided for the recording or reproduction of an image, the locking device 29 of the measuring device being controllable by a drive device 50 for a sealing member of a film cassette K inserted in the device.

Dependent claims

A photographic recording or reproducing device for accommodating a film cartridge for taking an elongated film and having a film entrance opening for enabling passage of said film therethrough, and a sealing member movably mounted at said film cartridge, for selectively sealing said film entrance opening, said photographic recording or reproducing device comprising:

(a) film transportation means (13) for transportation of said film along a film transportation path wherein said film is suitable for successively recording or reproducing images on or from a plurality of frames on said film;
(b) film metering means having an engagement member (18) rotatably and displaceably mounted, for successively engaging in holes of a peripheral perforation of the film when the film is transported by said film transportation means (13) along said transportation path;
(c) locking means (29) for locking said film transportation means (13) when said engagement member (18) of said film metering means engages in a hole of said peripheral perforation of the film;
and
(d) drive means (5) for moving the sealing means of a film cartridge when accommodated to the photographic recording or reproducing device, from a non-sealing position in which said film entrance opening is not sealed, to a sealing position in which said film entrance opening is sealed;
wherein
(e) said locking means (29) are controllable by said drive means (50) so as to become inoperative when after completely recording or reproducing images on or from said plurality of frames of the film and before the sealing member of the film cartridge has completed movement to the sealing position by said drive means (50).

(a) film transportation means (13) for transportation of said film along a film transportation path wherein said film is suitable for successively recording or reproducing images on or from a plurality of frames on said film;
(b) film metering means having an engagement member (18) rotatably and displaceably mounted, for successively engaging in holes of a peripheral perforation of the film when the film is transported by said film transportation means (13) along said transportation path;
(c) locking means (29) for locking said film transportation means (13) when said engagement member (18) of said film metering means engages in a hole of said peripheral perforation of the film;
(d) frame counting means (45) provided for counting frames of the film when transported by said film transportation means (13);
and
(e) drive means (50) for moving the sealing means of a film cartridge when accommodated to the photographic recording or reproducing device, from a non-sealing position in which said film entrance opening is not sealed, to a sealing position in which said film entrance opening is sealed;
wherein
(f) said drive means (50) and said locking means (29) are operatively connected to said frame counting means (45) so that said frame counting means (45), when having reached a predetermined counting position, control said drive means (45) so as to move the film entrance sealing means to the sealing position, and control said locking means (29) so as to become inoperative.
