Abstract
Abstract A digital recorder for simultaneously printing and punching digital data, such as vehicle traffic information, on the same tape is described. The recorder employs an electronic read-write memory including a digital counter between a data signal input and a step motor which rotates a punch cam drum and a print wheel on the same shaft. The punch cam drum includes a plurality of cam discs having cam projections and recesses arranged in a binary code to provide a binary coded decimal readout for recording the digital data on punched tape. As a result of such memory, the digital information can be recorded at a slower rate and at a later time than it is received. A pressure sensitive printing tape is employed for recording both punched and printed information. A second motor moves a punch head to cause punch pins to engage the punch cams and to punch binary coded holes in the tape. Such punch head also has a print anvil resiliently mounted thereon for causing the tape to strike the print wheel and print numbers or characters thereon corresponding to the binary coded holes punched therein.

Claim 2
Dependent Claim
161 words
A punched tape recorder in which the improvement comprises: rotary cam means including a plurality of cam recesses and cam surfaces arranged in a binary code to provide at a readout position a different number or character for each of a plurality of rotational positions of said cam means; motor means including a cam motor for rotating said cam means between said rotational positions in response to electrical signals applied to said cam motor; punch means for punching a tape with holes arranged in said binary code in response to punch pins engaging said cam recesses and cam surfaces at said readout position; input means for supplying input data as electrical input signals; and electronic memory means for receiving and storing a plurality of data input signals supplied thereto by said input means, and for producing a corresponding digital data output signal which is applied to said cam motor means to cause said cam motor means to rotate said cam means.
Claim 3
Dependent Claim
32 words
A recorder in accordance with claim 1 in which the memory means includes a digital pulse counter and the input means supplies said data input signals as digital pulses to said memory.
Claim 4
Dependent Claim
26 words
A recorder in accordance with claim 2 in which the digital input pulses are grouped in discrete binary coded words which are supplied to said memory.
Claim 5
Dependent Claim
31 words
A recorder in accordance with claim 1 which also includes a print means for printing on said tape data numbers or characters corresponding to said coded holes adjacent to said holes.
Claim 6
Dependent Claim
46 words
A recorder in accordance with claim 4 in which the print means prints said numbers or characters simultaneously with the punching of said holes and includes a print wheel mounted on the same shaft as said cam means, said shaft being connected to said cam motor.
Claim 7
Dependent Claim
30 words
A recorder in accordance with claim 1 in which the cam motor is a step motor which rotates said shaft intermittently in response to receipt of the stored input signals.
Claim 8
Dependent Claim
29 words
A recorder in accordance with claim 4 in which the punch tape is pressure sensitive so that it prints said numbers or characters on contact with a print element.
Claim 9
Dependent Claim
53 words
A recorder in accordance with claim 1 in which the memory means includes a digital read-write memory circuit having digital data input pulses applied thereto which it stores to provide a multiple digit data output signal which is read out serially to the cam motor means and punched one digit at a time.
Claim 10
Dependent Claim
52 words
A recorder in accordance with claim 8 in which the cam motor is a step motor operated differentially by said memory means to cause the cam means to rotate directly from one punched digit number to another of the same data output signal without homing the cam means to a reference setting.
Claim 11
Dependent Claim
109 words
A recorder in accordance with claim 2 in which the counter is a serial input, serial output shift register whose output operates the cam motor means and causes the punch means to punch a multiple digit data number on the tape one digit at a time, each punched digit corresponding to the setting of a single rotary cam means, and control means for subtracting the numbers to be punched from the stored number in said shift register by converting the code of the stored number, and for adding to said stored number any input pulses supplied by said input means during the punching period of the multiple digit number.
Claim 12
Dependent Claim
78 words
A recorder in accordance with claim 1 in which the punch means includes a punch head having a plurality of apertures through which said punch pins extend to punch holes in said tape, carriage means for moving said pUnch head toward and away from said cam means, and punch motor means for operating said carriage means to cause punching upon receipt of a control signal corresponding to the operation of said cam motor means by the memory means.
Claim 13
Dependent Claim
57 words
A recorder in accordance with claim 11 in which said punch motor means also operates a tape advance ratchet means for advancing said tape one step for each punching operation, and said punch means and cam means cause the digits of the readout number or character to each be punched at different longitudinal positions on said tape.
