and the eye of the observer. The lens is adjusted by means of a knob 35 mounted on a shaft carrying a worm gear which meshes with a rack 36 secured to the carrier 10.
The lens carrier is suspended from the to 11 of a cabinet 12 by springs 13. The ca inet is situated at the rear of a booth 14 occupied by the observer.
The booth is indicated by dotted lines, ex-
cept for the portion facing the observers po-,
sition, which is shown broken away and in section.
The observer occupies a chair 15 fixed to the floor 16 so that he faces the scanning and image producing mechanism.
At both sides and in front of the chair are compartments 18 lined with shielding materialand provided with transparent windows. on the side adjacent the chair. These compartments enclose groups of photoelectric cells which are actuated by light reflected from the face of the observer and are connected in parallel to an amplifier 40 and a circuit 41 through which the image current wave is su lied for transmission to another station.
e chair 15 is so placed that, when occupied by a person of average stature, he will in the optimum position for scanning The magnifying lens 9 is used to to uce an ima e which appears to be some nce back 0 the lamp.
Directly in front of the observers position, there is a compartment 20 constituted by the wall 19, a shelf 21, and a screen 22 mounted in a frame 23.
The wall 19 is provided with an opening 24 and the screen 22 carries a light transparent window 25. The scannm beam passes through the upper portion of t e 0 enm 24 and window 25, and the imageo the 0 er observer is viewed through the lower portion.
Upon the shelf 21, between the wall 19 and screen 22 is a loud speaker 26.
Adjacent the top of the opening 24 is a microphone 27 mounted on a bracket 28. h
The microphone 27 and loud speaker 26 have their axes parallel so that there is no direct transfer of sound waves from one to the other. To aid in giving the illusion that the sound emanates from the image, the axes of the microphone and loud speaker liein a vertical plane passing through the middle'of the opening. 24 I The screen 22 is made of fibrous material stretched upon the frame 23, so that it does not serve to transmit sound waves between the microphone andvloud speaker. Theloud speaker is also placed as close as possible to the image position to assist the illusion that the voice emanates from the imager The illusion of a face-to-face conversation may be enhanced by using material for the screen which tends to dampen the sound waves of another party, to the occupant ,ously operable two-way television whereby the voice appears to originate at the point where the image is formed.
Speech currents produced by the microphone are amplified in the amplifier 30 and transmitted over a channel, illustrated by way of example as a line 31, to a loud speaker, corresponding to 26, at the other station.
'Speech currents originating in the microphone corresponding to 27, at the other station. arrive via a communicationg channel, herein exemplified as a line 32, and are transferred. through the transformer 33 to the loud speaker 26.
A glass partition 34 excludes noises, produced by the motors, discs, etc. from the booth and thereby prevents them from interfering with the operation of the telephone instruments and from annoying the occupant of the booth.
The present invention provides a system in which two parties may carry on a telephone conversation while each has an unob- 'structed view of a complete image of the face of the other, and their voices appear to emanate at a point where the respective images are formed, whereby the illusion of a face-to-face conversation is materially enhanced.
What is claimed is:
1. A combined telephone and simultaneously operable two-way television system including a plurality of stations, a booth at each station, an image integrator and analyzer associated with each. booth and o rative with respect to a person therein, an telephone instruments in each booth but out of range of said analyzer.
2. A' combined telephone and simultaneously operable two-wa television system comprising a plurality 0 stations each having a booth, means for presentin an image of an object to an occupant of sai booth and for scanning a field within said booth, and telephone instruments outside the field of said scanningmeans.
3.'A combined telephone and simultaneously operable two-way television system comprising a plurality of stations each having a booth, means for scanning an occupant of said booth and for presenting an image s view, and a pick-u microphone and loud speaker outside the eld of said scanning means.
.4. A combined telephone and simultaneously operable two-way television system comprism a plurality of stations each having a boot means for scanning an occu ant of said booth and for presenting to sai occupant an ima e of a party at another station, and a lou speaker adjacent said image. 5. A combined telephone and simultanesystem comprisin a plurality of stations each having a boot meansvfor scanning an occupant of said booth and for presenting an image of another party to" the occupa'nts' view, a
