Optical and magnetic reader for film editing machines

Claim 2

In a film editing apparatus having a plurality of gangs mounted on a synchronizer for single and double system film with sound and picture tracks and having a film picture viewer through which single system sound and picture film passes onto one of said gangs, the improvement of which comprises: an optical sound readout system located in a separable housing adjacent said synchronizer gang comprising a lamp, focusing lens slit, and solar cell, and means for establishing electric contact between said solar cell and said lamp, said focusing lens slit and lamp being stable mounted in a first unit of said housing adjacent said synchronizer gang, and said solar cell being mounted in a second unit of said housing, said second unit being adapted to be engaged with said first unit when in use, and to be readily disengaged therefrom without altering the position of said focusing lens slit.

Claim 3

Said film editing apparatus of claim 1 which comprises, in combination the additional improvement, of a magnetic readout and playback system located adjacent said synchronizer gang comprising a magnetic sound playback means, having an adjustably magnetic sound playback head mounted thereon, said sound playback means being pivotally mounted on a standard so as to be located precisely over said sound track of said film when in use and to be disengaged from said sound track when not in use.

Claim 4

In a film editing apparatus, as recited in claim 2, in which the optical readout system and the magnetic playback system are accommodated adjacent and operable optionally on the same gang of the synchronizer.

Claim 5

In said film editing apparatus of claim 1, wherein additional gangs are provided on said synchronizer for double system film.

Claim 6

In a film editing apparatus of claim 4 wherein the picture viewer is mounted adjustably slidable on a platform to align itself with a plurality of gangs on the synchronizer for optical sound playback of single or double system films.

Claim 7

In a film editing apparatus, as recited in claim 1, in which said synchronizer gang is actuated by a normally operated foot pedal by way of a synchronous motor.

Claim 8

In a film editing machine: a platform; a housing means slidably arranged on said platform; a viewer for the viewing of picture tracks of a film accommodated in said housing means; power supply means for operating the viewer; an amplifier arranged in said housing means; magnetic heads arranged adjacent the housing means for playback of double system sound strips thereon; guiding means situated adjacent the magnet heads for guiding of sound tracks of the film over said magnetic heads; mixing control means for playback of sound tracks over the magnetic heads arranged in front of said guiding means; power supply means for operating the amplifier, mixing control means, and magnetic heads; a speaker arranged adjacent and receiving signals from the amplifier for sound production from the playback of the magnetic heads; a housing arranged below the speaker; a motor accommodated within said housing; a synchronizer arranged adjacent and actuated by the motor; a plurality of gangs, accommodated in and actuated by the synchronizer for the synchronous transport of picture and sound tracks; guide roller pairs, mounted adjacent each of the gangs to facilitate the transport of said film and sound tracks; optical sound reading means for receiving a playback of single system film tracks, said optical sound reading means being mounted adjacent one of the gangs, said optical reading means comprising a top and bottom portion, the top portion of which contains a power supplying solar call, and its bottom portion holding a focusing slit and optical lighting means; and magnetic sound playback means for single system film tracks, the magnetic playback means being arranged adjacent said same gangs as said optical reading means.

Claim 9

In a film editing machine: a platform; a housing means slidably arranged on said platform; a viewer for the viewing of picture tracks of a film accommodated in said housing means; power supply means for operating the viewer; an amplifier arranged in said housing means; magnetic heads arranged adjacent the housing means for playback of double system sound strips thereon; guiding means situated adjacent the magnet heads for guiding of sound tracks of the film over said magnetic heads; mixing control means for playback of sound tracks over the magnetic heads arranged in front of said guiding means; power supply means for operating the amplifier, mixing control means, and magnetic heads; a speaker arranged adjacent and receiving signals from the amplifier for sound production from the playback of the magnetic heads; a housing arranged below the speaker; a motor accommodated within said housing; a synchronizer arranged adjacent and actuated by the motor; a plurality of gangs, accommodated in and actuated by the synchronizer for the synchronous transport of picture and sound tracks; guide roller pairs, mounted adjacent each of the gangs to facilitate the transport of said film and sound tracks; optical sound reading means for receiving a playback of single system film tracks, said optical sound reading means being mounted adjacent one of the gangs, said optical reading means comprising a top and bottom portion, the top portion of which contains a power supplying solar call, and its bottom portion holding a focusing slit and optical lighting means; and magnetic sound playback means for single system film tracks, the magnetic playback means being arranged adjacent said same gangs as said optical reading means.

Claim 10

In a film editing machine, as recited in claim 7 in which the viewer is mounted adjustably slidable on a platform to align itself with a plurality of gangs of the synchronizer for optical playback of single or double system films.

Claim 11

In a film editing machine, as recited in claim 7 in which the top portion of the optical reading means is dismountable from the bottom portion thereof, without disrupting the set alignment of said remaining bottom portion.

Claim 12

In a film editing machine, as recited in claim 9, in which said top portion of the optical reading means is provided with externally projecting holding means for handling and removal of said upper portion from its base portion.

Claim 13

In a film editing machine, as recited in claim 7, in which the magnetic playback means is mounted adjustably on a pivoting arm arranged on a standard adjacent one of the gangs, for accurate positioning of the magnetic playback means on the sound track to be read while moving over one of said gangs and for its subsequent removal therefrom when not in use.
