22, a Separation button 23, a Code button.

  
  <EMI ID = 66.1>

  
Character button and a Jump button, called
26-29, respectively.

  
Only a brief discussion of the configuration and operation of the composition unit 1, Fig. 1, is given here, since the detailed explanations can be found in the prior art. The compositing unit includes a single element print head 8 which is operated by selection mechanisms which rotate or tilt this head. Generally speaking, the print head

  
8 has all the characters of a character style arranged around its periphery. The head is rotated or tilted to select characters under control of links that are actuated in response

  
  <EMI ID = 67.1>

  
  <EMI ID = 68.1>

  
fed against a document, such as document 5, to print the selected characters.

  
A document placed in composition unit 1 cannot be

  
can move sideways, from left to right,

  
and the print head B is moved during printing and spacing, alongside the document.

  
Composition unit 1 used a memory consisting of a lug wheel to store the exhaust values mechanically as they were

  
as typing takes place and these values will be used later in printing operations

  
and justification.

  
The composition unit is changed

  
so as to serve as an input / output device in this

  
which relates to the recording and reproduction of signals on medium 10 during processing in unit 2. Dialing unit 1 is also preferably modified to include transmit contacts.

  
These contacts generate signals during the printing operations, of the composition unit 1 and they are brought to the unit 2 containing the cards to carry out the recording in the tracks 11 and these signals

  
are generated during the formation of information

  
do justification for the data as recorded.

  
The composition unit 1 also includes a translation unit 25 for performing the automatic escape operation of the composition unit.

  
1 during signal reproduction in pistas

  
11, on support 10 in order to automatically produce a printed copy justified as indicated in the right column on document 5.

  
The translation unit uses a mechanism of character selection, escape, and print suppression. The dial unit is automatically actuated to provide varying increments of spacing, between words and / or characters in response

  
received signals, which are recognized to perform

  
the selection and simultaneous actuation of the character key levers and a print suppression mechanism. The set of character key levers are selected according to the desired escape width for the individual spaces while the simultaneous selection and activation of the print suppression assembly prevents printing.

  
To obtain spacings of various values,

  
one of the various key lever assemblies normally. used for printing characters of different widths is selected and operated at the same time as the print suppression assembly. More specifically, a source of information leads to

  
  <EMI ID = 69.1>

  
or functions to be performed, and an additional signal

  
to operate the print suppression mechanism. In a typical case, 3 to 9 units are selected

  
under command character selection lines.

  
The translator has seven (7) code cursors,

  
  <EMI ID = 70.1>

  
and a print suppression slider. The translator also includes seven (7) selection magnets which command <EMI ID = 71.1>

  
When placed in a system

  
such as that shown in FIG. 1, the composition unit 1 can include means for carrying out the operations

  
justification, manual and visual, In this

  
case, the composition unit 1, includes an assembly

  
indicator tubes 45, a space bar value dial 46, a space bar quantity dial
47, a justification lever 48, to establish a

  
Reading operating mode and a Writing operating mode and it may also include a dial

  
49 to automatically select the printing degrees or to manually set the printing degrees desired by the operator. Under these conditions, the unit

  
Composition 1, may include a separate Ecartemont selector lever 50, which is used to select the spacing corresponding to the character style as indicated by a color coding on the print head 8. The assembly 45 tubes has positions

  
of corresponding tubes which are color coded.

  
  <EMI ID = 72.1>

  
tube assembly 45 and bringing it to the color selected by lever 50, This will position one of the windows 51 or 52 used by the operator to visually determine the justification information for each line during printing operations . Each window has an associated indicator scale

  
  <EMI ID = 73.1>

  
a certain number of bars of .color, up to twenty ast unintended to rotate inside the assembly

  
  <EMI ID = 74.1>

  
particular of space bar operations which may occur during a printed line "

  
  <EMI ID = 75.1>

  
the space bar.

  
When the operator types a draft, each time an operation of the barra

  
  <EMI ID = 76.1>

  
45 indicates a rotation step. At this moment a different color appears at the far left of the window

  
  <EMI ID = 77.1>

  
  <EMI ID = 78.1>

  
for the current row, she energized the outside of indicator assembly 45 and slid the tube sideways over the color bar that was placed in the window. A ringtone advises the opera: on that

  
must approach the margo on the right. When printing is complete for the current line, the operator makes

  
  <EMI ID = 79.1>

  
such as window 51. These readings consist of a color in the window and a number on the scale.

  
54. The number on scale 54 is determined by the

  
  <EMI ID = 80.1>

  
color indicates the unit value of the space bar which is to be used during subsequent typing of the line to produce a justified line while the position is on; of scale 54 indicated the amount of Long Gaps to select in the line during printing.

The magnetic card processing unit, Figures 3-7 is designed to receive an individual magnetic recording card 10, move the card and bring it into position for recording. <EMI ID = 81.1>

  
on the map, to be moved incrementally, the map forward when recording of individual characters takes place and identifying the end of information for a particular line on the document such as

  
  <EMI ID = 82.1>

  
of the next track by a high speed reversing action with simultaneous switching from the current information track to the next information track.

  
In figure 3, the unit containing

  
  <EMI ID = 83.1>

  
  <EMI ID = 84.1>

  
03 to communicate a rotational movement relatively

  
  <EMI ID = 85.1>

  
65 in operation. Unit 2 includes magnets, Forward, Reverse, High Speed, and Forward, called 70-73 respectively to effect the relative movement of the board 10 in front of a transducer head 75 for

  
  <EMI ID = 86.1>

  
information tracks 11 and to effect a relative movement of the card 10 to position the transducer 75 from one track to another, for example, by the action of the advancement magnet 73.

  
Initially the selected card
10 is placed in a slot 78, Fig. 4. The Advance magnet 73 and the transducer 75 are mounted.

  
  <EMI ID = 87.1>

  
74 and which slides on a support rod 80. The carriage
79 is normally placed on the left in the figures

  
3 and 4 to scan the first information track

  
11 on card 10. Usually pressing one of the mode keys, such as Record and Playback keys 20 and 21, Figure 2a, energizes the Front magnet 70. A roller 83 which is brought into contact. with an inserted recording card is associated with the Front magnet 70. (The Rear magnet 71 and the High Speed magnet 72 have associated rollers.
84 ot 85). In fact the card 10 is brought to the initial position determined by its contact with

  
a 90 card switch lever and transfer

  
lever 90 which operates a card switch

  
  <EMI ID = 88.1>

  
we de-energize the Front Clutch magnet 70 st the card
10 is then a recording position of an initial character. Establishing a mode of Restitution, the carts

  
10 is advanced a sufficient distance to read

  
the first character in the information track.

  
Each of the magnets. Before behind,

  
  <EMI ID = 89.1>

  
clutch elements 91, 92 and 93 which are fitted

  
rotating their rear ends and which at their front end support rollers 95, 96 and

  
  <EMI ID = 90.1>

  
continuously driven through the gear trains 65 when the motor 60 is running. Each of the magnets 70, 71 and 72 is also associated with an armature 103, 104, and 105, to illustrate the operation of the gears and clutches, to achieve the relative movement of the card 10

  
it is assumed that the Avant 70 magnet is energized. This causes a rotational movement of the frame 103 in the direction of clockwise as indicated by the arrow 106, figure 7. The movement

  
of the frame 103 in the direction of clockwise causes the rotation of the square 91 around

  
center of gear 107 and rotates the center of gear 110 clockwise

  
  <EMI ID = 91.1>

  
contact between these two gears. The support element
95 is mounted with gear 110 and the action of rotating clockwise from the square

  
91 brings the roller 95 against the roller 83 which

  
  <EMI ID = 92.1>

  
83.

  
A similar clutch and drive action takes place with the other frames, brackets, gears, and rollers associated with the Rear magnet
71 and the High Speed magnet 72. The Rear magnet
71 is normally energized to effect relative movement of the carrier 10 with respect to the transducer

  
75 Back. The Speed Rumble magnet 72 is energized, to effect a High Speed movement of the medium

  
10 relative to transducer 75.

  
In the previous way, a movement

  
i relative is made between the support 10 and the transducer

  
75 in order to scan one of the information tracks 11

  
either during Recording or during Playback. The sweeping action is usually performed by

  
increment especially during a recording operation. That is, only a sufficient relative movement of the

  
support 10 and transducer 75 is made to

  
take into account an individual character when each

  
function and information character is introduced

  
using the keyboard 3. The end of the information in a

  
data track 11 is indicated by the appearance '

  
a Carriage Return signal.

  
The support 10 ordinarily carries a

  
sufficient number of tracks to take into account any

  
the amount of printed lines that can be expected while preparing a document such as a letter.

  
For example, support 10 can carry up to 9,140

  
tracks or more, as desired. With the device

  
scan, each individual printed line on

  
the document, such as document 5, in figure 1,

  
has an associated storage track 11, on the support

  
10. There is an advantage with the coordinated layout

  
line by line and track by track described here, since

  
is possible to extend or contract the information

  
contained in a particular line without affecting

  
the information stored on the other plates on the support 10. Each information track 11 can store a large number of characters, this number

  
being greater than the maximum number expected in

  
individual lines, of copy printed on the document 5. Usually the printed line is

  
completed before reaching the maximum capacity of

  
the information track on support 10. Since it is

  
If this is the case, it is possible to change individual lines for example, by placing additional words up to the maximum capacity of the associated track on the medium

  
10 and / or delete characters or words from the

  
again to review the stored information.

  
The provisions of the present invention aim to enable the processing of magnetic cards in a fast and efficient manner and provide new mechanisms and circuits to carry out this processing and to use the advantages.

  
tiling line by line, track by track.

  
At the end of the scan of an individual track 11,

  
on support 10 it is usually necessary

  
that the transducer 75 and the support 10 are moved relative to each other to put the transducer

  
75 next to another information track 11, to perform the scanning operations of this track.

  
This is done by the excitation of the advancing magnet.
73.

  
The advancement magnet 73 is part

  
an advancement assembly 74 which is associated with

  
a drive screw 76. The advancement assembly 74 comprises a certain number of pawls to effect the track-by-track advancement of the carriage 79 relative to

  
to the drive screw 76. The drive screw

  
76 has a helical configuration, the pitch of the teeth corresponding to the desired increment between successive information tracks 11 on the carrier 10. To perform rectilinear scanning of individual information tracks 11, the drive screw 76 may have a tooth and / or a spline associated with each track

  
  <EMI ID = 93.1>

  
That is, the teeth will not be arranged according to

  
a spiral helix continues along the drive screw. However, you can use any layout

  
to advance track by track the head 75 by

  
relative to support 10.

  
  <EMI ID = 94.1>

  
87 which is used to disconnect the entire advancement assembly

  
74 of the drive screw 76 and allow manual positioning of the transducer 75 relative to the support 10

  
and more particularly with respect to the particular information track 11 on the support 10.

  
It may be desirable in some

  
case of realizing automatic feeding and scanning of individual recording cards, such as

  
card 10. In this case, one can use a device capable of maintaining a multitude of individual recording cards in a spinning drum configuration.

  
Means may be provided for positioning a particular row of cards relative to a transducer station to then access a particular card for scanning and for performing a Record or Playback operation while scanning individual lines of information. on the support.

Clutch magnet 127 is used to move

  
the card 121 in front of the transducer 125 to perform

  
scanning an individual information track

  
122. The unit has a particular utility for inventory operations, or other, where it is desired to record

  
digital information on a card 121. This

  
is carried out by pressing the digital keys 0-9 which are located on the keypad 129. Pressing

  
the Stop key (STP) 130 records a Stop code on card 121. In the same way

  
  <EMI ID = 97.1>

In summary we can say that a Record mode is established by pressing a Record key.

  
  <EMI ID = 120.1>

  
from the printer resulting from the pressing of keys on the keyboard. During Record mode

  
and the Restitution mode, the characters are introduced

  
in a register made up of eight rockers called

are synonymous.

  
Returning to the Operating mode

  
in Registration, the TR1-TR8 switches are reset

  
to their zero condition and are then set to states representing the code combination of a first character supplied in response to a key press on

  
the keyboard. This involves closing the contacts called R1, R2, R2a, R5, T1, T2, control (CK) and

  
No. 8. The Control contact can also be referred to as a shift contact (SH) as shown in the figure.
13b. The printer includes a number of contact breakers as follows!

  

  <EMI ID = 124.1>

At time C1, the rockers TR1-

  
TR8 are set according to the configuration of

  
code representing the character or function selected in the printer. A non-end of character level

1, 2, 3 or 4 pulses is separated from the pulse group

  
previous or next by an interval of approximately 2 milliseconds, which is obtained under the control of the Group monostable. With the assembly proceed, the

  
characters are of variable length and therefore,

  
  <EMI ID = 130.1>

  
depending on the code combination and the number of pulses generated for each character.

  
For example, the shortest character

  
  <EMI ID = 131.1>

  
pulse being separated by two milliseconds approximately, and it will occupy on the medium, an interval which required

  
  <EMI ID = 132.1>

  
The longest character will have the following configuration:

  

  <EMI ID = 133.1>


  
In this case the four groupa? pulses are also separated by intervals of approximately two milliseconds and the total character length

  
is approximately 24 milliseconds. It exists

  
an additional space with each series of characters

  
and this space is not occupied by impulses.

  
In a typical case, approximately 20 milliseconds

The reproduction of information from the medium is initiated by pressing a Restitution key, such as the Restitution key.

Registration and Justification

  
The fundamental recording technique

  
  <EMI ID = 197.1>

  
in the form of variable length code combinations. The operations of the dialing unit and the magnetic card unit combining to produce a copia justifias on a document. The justification operations will be described for the

  
Single Column justification mode.

  
Operator types first

  
a draft, stopping where the lamp <EMI ID = 198.1>

  
the line can be justified. While the copy

  
is being typed, document information and justification information are recorded

  
  <EMI ID = 199.1>

  
The operator selects a gauge

  
  <EMI ID = 200.1>

  
and a justified line length desired (in unit

  
  <EMI ID = 201.1>

  
by setting the dials in Figure 2b C switches shown in Figures 20-22c).

  
  <EMI ID = 202.1>

  
  <EMI ID = 203.1>

  
than a certain number of complementary registers. The operator places the device in Record mode Justification which energizes the front clutch, figures

  
3 and 11d. When card 10 is inserted, it is moved until it contacts the switch.

  
card 100 are transferred to figure 4. Initially,

  
  <EMI ID = 204.1>

  
sufficient to take into account the maximum character length but without actually saving. This

  
  <EMI ID = 205.1>

  
take into account the character of justification associated with the information track. The main register is reset to "0".

  
The operator now types a line of text. When the first character is typed the main register receives the encoded information and decodes it to indicate: the number of units

  
  <EMI ID = 206.1>

  
using an Increment translator.

  
The complement of this number is recorded

  
  <EMI ID = 207.1>

  
CU3, after which the MV multivibrator advances

  
CU1-CU3 registers at 0, which generates a pulse for each escape increment, which will be introduced into the Unit or Increment count register

  
  <EMI ID = 208.1>

  
  <EMI ID = 209.1>

  
Count scale to B. This allows a line of 8 units length to be made using either 12, 14 or 16 gauge, Unit count and line length registers are set when the operator sets the switches , Figure 2b, a switch indicating the integer number of units of length in a line and the second indicating the number of sixths of units (or pica) above the integer number of units in the line. The complement of the number of units recorded on the dial is placed in the counting scale at 8. Likewise, the complement of the number of picas is placed in the counting scale .'18 according to the spacing selected by the 'operator. For example, if the operator chooses a gauge of 12 and wishes to type a line 34 picas long the dial

  
  <EMI ID = 210.1>: total 34). We can set up a conversion table to show units and fractions of units

  
for a given number of picas and a given spacing. The switch settings cause the setting of a 3 in the counting scale to 8 indicating that 5 units remain and an 8 in the counting scale to 16 indicating that 8 x increments or 4 picas

  
  <EMI ID = 211.1>

  
to 16 is reset to 4, when the dial unit is set to a spacing of 12. If it is set to a spacing of 14, the counter is reset to 2,

  
  <EMI ID = 212.1>

  
However, the device is restored to 8 because of the dial setting for this example.

  
Each character is typed

  
and decoded and causes the advancement of the unit counter of the line. When a space is typed '.. by the operator the counter is advanced three units. However, each typed spacing is also counted and recorded in the WS1-WSS Word Space counter.

  
When the number of spaces between words. is equal to the complement of the count in the counting scale at 16 with the complement of the value in

  
  <EMI ID = 213.1>

  
the spacing comparator records this fact in the J register, indicating that the line can now be justified. When the line can be justified <EMI ID = 214.1>

  
Return code Carriage terminates the line. If the line

  
cannot be finished, and that we have just started

  
  <EMI ID = 215.1>

  
justification remains on after Backspace,

  
  <EMI ID = 216.1>

  
a Cart return. If the word is too long it can

  
be hyphenated in the next three characters and again a carriage return ends the line.

The Cart Return code activates the clutch

  
  <EMI ID = 217.1>

  
MV multivibrator causes the main register and the increment register to count. The Main Register

  
  <EMI ID = 218.1>

  
binary count to 256. The register is initially set to 1111 1111. If any increment remains

  
  <EMI ID = 219.1>

  
in all cases the next pulse from MV will be counted by the other three unit registers.

  
  <EMI ID = 220.1>

  
are divided by the number of spaces between word and

  
the quotient is recorded in the last three units of the main register. When the increment register is empty (0000000000) the multivibrator stops and the first five positions of the main register contain the value of the remainder.

  
The Front magnet is now actuated

  
and the information placed in the main register

  
is saved as the first character of

  
line. Then the Advance magnet is actuated

  
and transducer 75 is advanced one track and put

  
in position to record the first character

  
of the next line In this way the whole document tour is typed line by line, with

  
a justification character that precedes each line.

  
Once the document is complete the operator returns the transducer to the first line and places the machine in the Justification and Restitution mode which will be described in a later paragraph. Select Line Spacing and Length.

  
Devices are provided which are in the form of switches which can be adjusted

  
by hand, Figure 2b for the operator to select the character stylea spacing qon the print head 8 and the desired line length justified. The switches actuate the contacts shown

  
  <EMI ID = 221.1>

  
The operator selects the spacing by button 34, figure 2b. This conditions one of the DC circuits, figure 20, in order to provide an output signal to set the counting scale to 16 made up of the UC4-UC7 rockers, figures 15b and 18. We will refer to the beginning.

  
of the justification and recording mode description: to find switch settings, including

  
the distance switch.

  
The UCB-UC10 positions of the rockers

  
serve as a counting scale of 8 to store

  
a number represent the number of units of length

  
  <EMI ID = 222.1>

When the device has the means

  
  <EMI ID = 235.1>

  
and 13c combine with the circuit shown in Fig. 11d to control the various justification operations. We will also refer to the figures
15a-42b.

  
  <EMI ID = 236.1>

  
  <EMI ID = 237.1>

  
EOC exists in Figure 11a.

  
  <EMI ID = 238.1>

  
Now the operator places a card

  <EMI ID = 241.1>

  
A Division Complete signal from Figure 24, produces a Trigger signal.

  
  <EMI ID = 242.1> figure 13a. This signal is applied to a block II 171, figure 13a, and with the operation of the monostable <EMI ID = 243.1>

  
route the multivibrator clock. The sequences that

  
just described are indicated by the waves

  
in Figure 39, referred to as Record Start sequences.

  
  <EMI ID = 244.1>

  
operation, FIG. 13a, the device operates as if it were recording a character of maximum length, that is to say a character made up of 16 bits, arranged in 4 groups, of 4 bits each. However the transducer

  
  <EMI ID = 245.1>

  
'' no recording of digital information in

  
the information track. The effect of the foregoing operation is to operate the Front magnet for a sufficient time to leave the necessary space for the justification character at the start of the information track.

  
At the end of the recording sequence, the Progress Monostable, figure 23, provides a ,,

  
  <EMI ID = 246.1>

the end of the line. Triggering the Toggle

  
Typing Key is shown in Figure 39 In Figure 27, the keypad release magnet is energized to allow characters to be entered through the keypad, Figure 1. Printing and Saving Character "a". Stages JR-20 to JR-26.

  
Informational characters and space operations have escape values which are predetermined according to the following table

  

  <EMI ID = 248.1>


  
  <EMI ID = 249.1>

  
assumes that the first character introduced by the

  
  <EMI ID = 250.1>

  
recording with EOC and the character is recorded on the magnetic card 10 as described in

  
the previous fundamental recording sequence.

  
In time the transfer of the various transmission contacts in the printer 1, is identified particularly in Figures 37a and

  
b, 38a, b and c, and figure 36. to decode the escape of the character involved. An electrical indication of

  
the length of the exhaust is obtained by using the contents representing the rotation and the inclination

  
  <EMI ID = 251.1>

  
contacts No 8 figure 13b. Contacts # 8 are normally used as a parity indication.

  
There are 88 characters printed normally. Forty of these characters have an escape value

  
  <EMI ID = 252.1>

  
upper case letters or an escape value of 5 units in the case of lower case letters and 7 units in the

  
  <EMI ID = 253.1>

  
determined by use of the circuits shown in Figures 37a-38c. If a character is not

  
  <EMI ID = 254.1>

  
38c, it is assumed that it belongs either to the group,

  
  <EMI ID = 255.1>

  
escape values of "5 to 7" units. These two

  
groups are identifiable since the group of values. exhaust of 5 to 7 units is accompanied by a

  
parity bit (contact number 8), They are also identifiable since the shift contacts indicating whether they are

  
uppercase or lowercase. The circuits represented <EMI ID = 256.1>

When the Cl contacts in the unit

  <EMI ID = 258.1>

  
  <EMI ID = 259.1>

  
CU4, figure 33, are now triggered with the complement of the escape value of the character

  
"at". Then the MV2 multivibrator starts working

  
  <EMI ID = 260.1>

  
UC1-UC3, figures 15b and 17, is energized and will now store the value for the character "a",

  
In figure 34, the UCR switch

  
is triggered when 6 pulses are entered into UC1-UC3. In this case, another impulse

  
  <EMI ID = 261.1>

  
  <EMI ID = 262.1>

  
  <EMI ID = 263.1>

  
Stages JR-27 to JR-33 ..

  
  <EMI ID = 264.1>

  
we assume that the next character introduced is

  
the character "t". Considering the table given previously, this character an escape value

  
of 4".

  
In figure 13b, the transmission contacts of the composition unit 1 are transferred and initiate the recording of the digital configuration of the character on the magnetic card 10. At the same time, the closures of the contacts are applied in the

  
  <EMI ID = 265.1>

  
escape value of character.

The transfer of the contacts of the switch

  
C1 in the composition unit triggers the rocker

  
UCR, Figure 34, if it was previously restored.

  
The complement of the escape value is introduced in the switches CU1-CU4, figure 33, as before. The MV2 multivibrator is started again in order to put the CU1-CU4 rockers to state "0",

  
When the MV2 multivibrator is operating, the positions

  
  <EMI ID = 266.1>

  
UC4, figures 15b and 18. This also restores the rocker

  
  <EMI ID = 267.1>

  
UC1-UC4 is identical to that shown in step JR-33 ot after the pulse sequence the rockers will contain a total count of 9 including the

  
escape values of "5" and 040 for characters

in order to produce a justified copy. The operator

  
can continue typing and spacing in the line until there is a minimum remainder which is determined by a J register input signal and a line remainder input signal

  
  <EMI ID = 273.1>

  
going to block AOI 176 which realizes the excitation of

to indicate that we have reached the zoster of Fin. Carriage Return Identification, Determination of Justification Data and Recording of Justification Data Steps JR-42 to JR-71.

  
In figure 42a it is assumed that a

positions TR1-TR5 are excited in figure 13b. Yes

  
it is assumed that the TR1-TR5 rockers serve as a ladder <EMI ID = 282.1> <EMI ID = 283.1>

  
WS5 to give an output signal RMR which stands for Main Register Restore. Consequently,

  
the sixth pulse in the train of 24 pulses will establish "0" in the rockers TR1-TR5 and in '

  
  <EMI ID = 284.1>

  
If we consider the other pulses in the train of 24 pulses the condition "0" everywhere will occur again for a count of "11", "16" and "21",

  
Assuming that there are 5 word spacings, a line remainder of 24 units indicates that the last spacing must be increased by a value "4" from the fundamental value of "3" to obtain a total of "7", and that each of the

  
  <EMI ID = 285.1>

  
"5" to get a total of "8". We will refer to

  
state JR-55 in the table where we can see that

  
pulses. 22, 23 and 24 establish conditions

  
"1" in positions TR1 and TR2 and that "4" units

  
are stored in position TR8.

  
When the 24 values in the rest of the line have been counted, the UC10 position switches to

  
at state "0". At this time the TR1-TR5 positions will store the number of long spacings needed and the positions

  
  <EMI ID = 286.1>

  
long spacings. When the UC10 rocker changes state, the Finished Division rocker is shown as 24,

  
is triggered.

  
Considering the mechanical operations involved, it will be recalled that the magnetic card

  
10 performs the reverse movement at high speed

  
at the start of the line, When the map switch contacts are transferred, the High Speed Rear clutch is de-energized, the Front clutch is energized again, the map switch contacts 100 are

  
transferred again and the 1D magnetic card is now in position for recording the justification character in the previously allocated space

  
at the start of the information track.

  
The switch from Finished Division, figura
24, being triggered, a Pos J pulse is supplied

  
  <EMI ID = 287.1>

  
  <EMI ID = 288.1>

  
the front clutch and in, figure 33, the Multivibrator

Multivibrator MV2 are applied to the main register positions TR1-TR8 in a comparable manner

  
to that used during character registration and the following Justification character is

  

  <EMI ID = 290.1>


  
  <EMI ID = 291.1>

  
saved in the position of the Justification character.,

  
Then, the Monostable of Advancement

  
in figure 23, becomes active and excites the magnet, of Advancement 73, figura 13a in order to advance <EMI ID = 292.1>

  
on magnetic card 10. Since the forward action occurs at the end of the position of the justification character of the previous line a standard spacing is automatically allocated at the beginning.

  
of the next line to store the character

  
justification for this line.

  
In figure 23, the Row rocker

Entering and Recording Data for the Next Line. All the sequences are shown in Figure 42b.

  
The individual printed information lines are printed on the document 5 in the previous manner and the associated information signals are recorded in the associated information tracks

  
on magnetic card 10, a justification character

  
  <EMI ID = 293.1>

  
used later during the RenderRestitution operation.

REFUND AND JUSTIFICATION

  
In order to print automatically justified copia lines, the JustificationRestitution key 31, FIG. 2b, is pressed. This activates the clutch Before and when the magnetic card 10

  
is inserted into slot 78, figure 4, it advances to the start of the information track which is supposed to be the first track on card 10, corresponding

  
on the first printed line of information. The justification character associated with the first information track is introduced in the positions of the Main Register

  
  <EMI ID = 294.1>

  
quer the number of spaces required. Information in the last three positions of the Register

  
  <EMI ID = 295.1>

  
determines the escape length for each word spacing.

  
In reality, the complement of * remained

  
  <EMI ID = 296.1>

  
once a word spacing is introduced by

  
the information track, the rest is reduced by one.

  
In this way, the number of long spaces is counted as these spaces are

  
read. When the last long gap is encountered, the Increment register receives a pulse which causes the quotient's complement to increase by one and

  
  <EMI ID = 297.1>

  
a. This reduces the length of the remaining Word Spaces by one, resulting in a justifias line.

to document 5. The control device of the spacing magnet is used directly each liver that

  
7 spacing units are required. Other,

  
character selection and print delete operation are used to perform the necessary incremental movement of the printhead 8

  
compared to document 5.

  
Identification of the Cart Return Code and Reproduction

  
  <EMI ID = 322.1>

  
The succession of operations continues

  
with the identification of the various characters for printing and codas spacing when they are encountered,

  
until a Cart Return code is identified,

  
  <EMI ID = 323.1>

  
Carriage Return, figure 13b, are transferred to <EMI ID = 324.1>

  
Then the Rear High Speed magnet
72 is energized to put the High Speed Rear clutch in the engaged position, and the advancement magnet
73, figure 13a is excited to move the transducer

  
  <EMI ID = 325.1>

  
card 10 backwards continues until 4 contacts ..

  
  <EMI ID = 326.1> .which the Rear High Speed magnet 72 is de-energized, The Front magnet 70 is energized in order, - to bring back the card, <EMI ID = 327.1>

  
the positions of the main register on the -figura
13b and the justification of the information line

  
  <EMI ID = 328.1>

  
completed.

  
Although the device has been described for a normal justification routine, it can

  
  <EMI ID = 329.1>

  
easily adapt to processing other functions

  
  <EMI ID = 330.1>

  
  <EMI ID = 331.1>

  
appropriate to establish the desired dialing operation. The individual registers are triggered and restored to conditions appropriate to the desired function. For example in the centering of a line

  
  <EMI ID = 332.1>

  
arithmetic are operated so as to divide the

  
24 by a factor "2" to initiate the spacing operations before printing and establish a balanced white spacing on the left and right ends of the line in question.

  
The system editing possibilities are described previously in the section Recording mode. In the machines of the prior art,

  
  <EMI ID = 333.1>

  
desired information, such as characters,

  
words, and lines with or without skipping and to recognize stop codes when placed

  
at suitable intervals in the recorded data. All the editing possibilities of these systems

  
can adapt to the system of the present invention

  
to produce an error-free copy and to allow

  
to mix the printing of data from the

  
recording medium and manual input

  
via keypad 3, on the dialing unit

  
1. The latter method is of course preferred only during a normal Restore operation, instead. of a Restitution and Justification operation.

  
In the prior art it is also possible

  
find the description of a revision assembly of <EMI ID = 334.1>

  
Cart and it is then available to allow the extension of an individual line by one character.

  
  <EMI ID = 335.1>

  
  <EMI ID = 336.1> <EMI ID = 337.1>

  
For example, if each track on the map can take into account 200 characters and the ligna moyenna:. only contains 150 characters, 50, additional character positions are available to expand, each individual line. Of course each line will vary

  
  <EMI ID = 338.1>

  
  <EMI ID = 339.1>

  
in recording, processing and reviewing data in a system of this nature.

LINE ADJUSTMENT

  
We find in the prior art the description

  
  <EMI ID = 340.1> of data on the medium according to a first predetermined format established by the margin settings

  
on the right and on the left with codes Spaces and

  
of the Carriage Return Codes, recorded as and

  
as they occur during typing. Then, if the margin limits are set to the same values as when the data was recorded, the

  
lines printed during reproduction will match in length and the data read from the media will be interpreted as recorded.

  
However in this case it may be desirable to change the data format by shortening or lengthening the lines on the document, while

  
using the data originally recorded

  
on the support. In the Line Readjustment Mode of Operation, the interpretation of characters stored on the media during Playback does not depend on whether those characters occur.

  
in a first portion of each line or in

  
the part end the line called "La Z6ne" or "Region". Carriage Return Codes occurring

  
in the Region perform a Carriage Return operation while Carriage Return codes occurring before that Region in the row are converted to space operations. Conversely, spacing codes occurring in the ending region

  
the line are converted to Cart Return codo

  
but are normally interpreted outside the region.

TRANSFER AND TRANSFER ADJUSTMENT METHOD

  
Other known types of operations

  
in the prior art are interesting for the systems described here: they are the transfer operations and

  
transfer adjustment operations. In one

  
or the other of these operations, the system is equipped with

  
additional recording unit.

  
Sometimes it becomes desirable to transfer information from one unit to another. In a fashion.

  
of the Transfer Type, the information

  
on one of the processing units is transferred to

  
the other processing unit with simultaneous printing of a document and no line readjustment. In

  
a transfer adjustment operation, the information

  
on one of the processing units is transferred &#65533;

  
the other unit in exactly the same way, but the printing of a document takes place under the readjustment conditions

  
that have been described previously.

  
In some cases, it is desirable

  
that the printing of a document takes place under command

  
from one or the other of the units any information being obtained from one unit and the other information being obtained from the other unit. A "Commutation" code in the recorded information and circuits

  
  <EMI ID = 341.1>

  
both units during information reproduction.

COMMUNICATIONS

  
The communication possibilities of

  
systems known heretofore, can be adapted into the present system in order to communicate the ordinary information from a registration card to

  
a device for use at the other end of a communication line or to transmit the information of the draft along with the associated justification character or justification signals which can be used to produce a justified copy directly by the 'means intermediary

  
telecommunications.

  
Other Changes!

  
  <EMI ID = 342.1>

  
be made to the mechanical assembly of the composition unit, the card processing unit or '

  
to means of telecommunication.

  
Regarding the processing unit

  
card, it may be appropriate in some cases

  
use only one track on the recording medium

  
10 and decondition the advancement of the transducer

  
75 to the other track. In this case a single line of

  
draft is saved in the selected track

  
with or without following justification information

  
operating mode. At the end of Playback mode,

  
in which the previously saved data

  
are obtained and fed to the printer, the same information track can now be used for the introduction of the draft associated with other printed lines

  
on the document in the composition unit.

  
Regarding the processing unit

  
card, the general function of the unit can be <EMI ID = 343.1>

  
conveniently recording and reproducing -

  
signals in the various information tracks and the incremental displacement of the transducers

  
step by step to access the individual information tracks.

  
It is evident that this relative movement

  
and relative displacement can be achieved by

  
  <EMI ID = 344.1>

  
  <EMI ID = 345.1>

  
linearly displaced along individual pistas

  
on support 10 to record and reproduce information and it can be moved in one track increments

  
  <EMI ID = 346.1>

  
  <EMI ID = 347.1>

  
10 to record and play back the information in the individual information tracks and then

  
  <EMI ID = 348.1>

  
to the transducer 75 to effect a relative displacement of the transducer 75 and the support 1Q in order to access

  
  <EMI ID = 349.1>

  
it may be desirable in some cases to establish an alternate scan of transducer 75 relative to

  
  <EMI ID = 350.1>

  
moved relative to the support 10, so that an information track is scanned in one direction

  
the next track is scanned in the opposite direction etc.

  
It may be desirable to provide mechanisms and circuits for the control of

  
  <EMI ID = 351.1>

  
  <EMI ID = 352.1>

  
or reproduction. Thus, by considering the operations of Recording, Restitution, Justification

  
and Recording and Justification and Restitution described above, this control device

  
document return is in service immediately upon depressing the associated mode command key to establish a first track position on the

  
card before energizing the mode lamp under the key.

  
Although it has been described in the foregoing and shown in the drawings, the essential characteristics of the invention applied to a mode of

  
  <EMI ID = 353.1>

  
those skilled in the art can make any modifications in form or detail that they deem useful, without however departing from the scope of said invention.
