Abstract
Abstract A tape reading device wherein a perforated tape travels in either direction upon a plurality of sensing star wheels. As the wheels penetrate the perforations in the tape, a circuit is energized causing signals to emanate. Associated therewith a motion sensing wheel penetrates the tape at equally spaced perforations so as to provide a continuous indication of the movement of the tape.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
156 words
A tape reader for reading the data on a multichannel perforated tape comprising, means for supporting the tape, a motor for advancing the tape, a plurality of sensing assemblies movable by the perforations in the tape, a plurality of contact levers operable by the movement of said assemblies, sensing means responsive to tension in the tape for signalling the end of the tape, means for stopping the motor, including a tape lid and a supporting frame therefor and a roller bracket pivotable in the frame having a roller mounted thereon riding the tape, a switch in series with said motor associated with the bracket having a resilient contact for biasing the roller against the tape, said switch being adapted to open the motor circuit when the tension in the tape overcomes the resilient force of said contact, and means emitting a steady stream of impulses for signalling the continuous advance of the tape through the reader.
Claim 2
Dependent Claim
156 words
A tape reader for reading the data on a multichannel perforated tape comprising, means for supporting the tape, a motor for advancing the tape, a plurality of sensing assemblies movable by the perforations in the tape, a plurality of contact levers operable by the movement of said assemblies, sensing means responsive to tension in the tape for signalling the end of the tape, means for stopping the motor, including a tape lid and a supporting frame therefor and a roller bracket pivotable in the frame having a roller mounted thereon riding the tape, a switch in series with said motor associated with the bracket having a resilient contact for biasing the roller against the tape, said switch being adapted to open the motor circuit when the tension in the tape overcomes the resilient force of said contact, and means emitting a steady stream of impulses for signalling the continuous advance of the tape through the reader.
Claim 3
Dependent Claim
22 words
The tape reader claimed in claim 1 wherein said motor is a DC pulse-type stepping motor and is operable in either direction.
Claim 4
Dependent Claim
42 words
The tape reader claimed in claim 1, wherein the means for supporting the tape comprise a guiding platform havinG a slot therein and said sensing assemblies are biased upwards through the slot against the tape to penetrate the perforations in the tape.
Claim 5
Dependent Claim
61 words
The tape reader claimed in claim 1, wherein said sensing assemblies comprise, a lever, a sensing star wheel on one end of said lever having a plurality of arms, and attached to a contact lever on the opposite end for biasing the arms into the perforations in the tape to allow the contact lever to complete an impulse transmitting circuit thereby.
Claim 6
Dependent Claim
59 words
The tape reader claimed in claim 1, wherein said means emitting a steady stream of impulses for signalling the continuous advance of the tape through the reader comprise, a motion sensing wheel driven in steady increments by the tape, and a contact lever actuated by said wheel adapted to engage a terminal each time the tape advances one increment.
Claim 7
Dependent Claim
13 words
The tape reader claimed in claim 1, wherein said tape is chadless tape.
Claim 8
Dependent Claim
13 words
The tape reader claimed in claim 1, wherein said tape is chad tape.
