Description

The invention relates to a recording device

  ment comprising a writing device which comprises at least one writing member, itself formed of at least one writing element and disposed on a rotating support, a relative movement occurring between the recording medium on which must be written and the

writing device.

  Such a recording device is known, from

  U.S. Patent 3,998,315, for example. This provision

  sitive has proven to be a relatively quick and economical device

  and has already proven itself. However, it turned out that the applica-

  tion of the known apparatus can be much more varied and extended if an appropriate reading device is added to it. We thus obtain many possibilities of application both in work

  normal reproduction than in the remote transmission of information

  o where, for example, several reading stations can supply

  a recording device or different recording devices

  They can be interrogated from a reading station.

  The invention therefore aims to supplement the known recording device with an appropriate reading device in order to

  to improve and increase the possibilities of application of the former.

  According to an essential characteristic of the invention

  tion, the recording device further comprises a reading device which comprises at least one reading member, itself formed of at least one reading element and disposed on a rotating support, a relative movement occurring between the support recording device to be read and the reading device, and transmission and / or storage means are provided for the transmission of the information read

  by a reading element to a writing element conjugated to it.

  An important feature of the inventive system

  tion is that the rotation that the recording device must perform

  Truly for recording information and the advance of the paper on which it is to be written are also used for the operation of the reading station. This leads, if desired, to a very economical construction and the two devices can, depending on one characteristic

  of the invention, be housed in a common envelope. It is however

  It is also possible to physically separate the reading device from the writing device and to transmit the information read and the synchronization pulses necessary to the writing device.

  by any transmission and / or storage systems.

  It is still possible to reproduce the information read not alone-

  lie to the same size on the paper on which is written but also

enlarged or reduced.

  Other characteristics and advantages of the invention

  will emerge more clearly from the description which follows more

  several nonlimiting exemplary embodiments. All of the examples

  crits contain supports in the form of circular disks for reading and writing organs, such as the printer known from the cited patent. The supports can naturally have other forms too. They can in particular consist of several arms, carrying the reading or writing organs or have another shape.

  FIG. 1 represents a recording device

  ment comprising a reading device 1 and a writing device

  2. The recording medium 3 to be read and the paper 4 to be written on are arranged one behind the other on the side surface of a cylinder 5 in this exemplary embodiment. This cylinder

  contains, on its axis, a shaft 6, on which the disks are wedged

  reading and writing positives 1, 2. The reading device 1 consists of a disc support 7 and reading members 8 which will be described in more detail with reference to FIG. 3 and which are

  arranged in such a way on the support 7 that they act radial-

  outward. The reading device 2 corresponds for

  the essentials of the rotary printer known by the United States patent

  United States of America 3,998,315 already cited, the design and function of which

  These are described in this document and are summarized below in relation to Figure 2. The device shown in Figure 1 further comprises an electric motor 9 which drives the shaft 6 directly and two transport rollers 10, cooperating with two

  pressure rollers 11> via a speed reducer 12.

  When the motor 9 is started, it rotates the shaft 6 therefore also the reading and writing devices 1, 2

  in the cylinder 5 and, via the reducer 12, it comprises

  simultaneously conveys the transport rollers 10 which advance the recording medium 3 respectively the paper 4 parallel

  to the axis of the cylinder in cooperation with the pressure rollers 11.

  Between the recording medium 3 and the reading members 8 on the one hand and between the paper 4 and the writing members 13 on the other hand, a movement is thus produced relating to two components: one produced by rotation of the reading device 1 or of the writing device 2 in a plane perpendicular to the recording medium 3 or to the paper 4 and the other prc. iite, at an angle of 90 relative to the first, by the forward movement in the direction of the length of the recording medium 3 respectively of the paper 4. As these movement components have a relationship which is fixed by the ratio transmission of the reducer 12, it is possible to obtain a uniform exploration or reading, line by line, of the recording medium 3 to

  through a slot 5a of the cylinder 5, respectively a uniform writing

  form line by line on the paper 4 through a slot 5b of the cy-

lindre 5.

  Figure 2, in combination with Figure 1, shows

  an example of arrangement of writing devices on a support

coide.

  The execution corresponds substantially to that of the bre-

  vet quoted on several occasions. The writing member, designated here by 13 ′, is pivotally mounted on the support 14 ′ at point 15 and is loaded by a tension spring 16 which attempts to keep it applied against a stop 17. At their ends opposite the points fixing 15, the writing members 13 'each carry one or more plotters 18, constituted by elastic metal blades for example. When the support 14 'is rotated, the centrifugal force pivots the writing members 13' against the force. springs 16 outwards, until the markers 18 touch the wall

  inside of cylinder 5 or, through slot 5b, paper 4.

  Figure 3 shows an exemplary embodiment of the

reading organs.

  Each reading member, designated here by 8 ', is pivotally mounted on a disc support 7' at point 19 and is pulled at rest by a spring 20 against a stop 21. Each reading member 8 'of the example shown comprises a or several light waveguides 22 which cooperate with an electronic assembly such as those of FIGS. 8 and 9. It is advantageous in this case that the number of guides 22 and their mutual spacing correspond to the number and the spacing of the tracers 18. In addition, as shown in Figure 1, the reading device 1 should include as much

  of reading organs 8 that there are writing organs 13 in a dis-

writing positive 2.

  When the support 7 ′ rotates, the centrifugal force pivots the reading members 8 ′ against the force of the springs 20 outwards, until the light wave guides 22 are in the immediate vicinity of the interior surface. cylinder 5 or recording medium 3 to read. If the recording medium

  ment 3 is lit, the light wave guides 22 can explode it

  line by line through the slot 5a of the cylinder 5 while the recording medium 3 is advanced and can transmit the

  luminosities received at one of the electronic assemblies mentioned.

  Figure 4 shows a recording device of another execution. This also includes a cylinder, 23, on the side surface of which a recording medium 24 to be read and the paper 25 on which to be written are arranged one opposite the other with an offset of 1800. The cylinder 23 contains a

  combined reading and writing device 26. It includes a support

  port 27, on which one of the latter can be arranged alternately

  the other of the reading members 28 and the writing members 29, which can be produced like those of FIGS. 2 and 3. The support 27 is wedged on a shaft 30 situated on the axis of the cylinder and controlled by a motor electric 31 which rotates at the same time,

  by means of a speed reducer 32, drive rollers

  port 33 offset by 1800 and each cooperating with a pressure roller

sion 34.

  While the motor 31 rotates the reading and writing device 26, the reading members 28, acting radially outwards, explore through a slot 23a of the cylinder 23, line by line, the recording medium 24 moved

  parallel to the cylinder axis by the transport rollers 33.

  The information represented by the different captured luminosities is transmitted by an electronic circuit like that of FIG. 8 or of FIG. 9 to the reading member 29 offset each time by 180 relative to the corresponding reading member 28 and also acting radially outward, to write the information line by line through a slot 23b of the cylinder 23 on the paper 25 that the

  transport rollers 33 advance parallel to the axis of the cylinder.

  FIG. 5 represents an execution of such a device.

  positive o the recording medium to read and the paper on which

  should be written are laid out flat.

  The recording device of this example includes

  takes a combined reading and writing device 35 which has a support 36, one of the faces of which carries the reading members 37 and the other side of which carries the writing members 38. Guide wheels 39 hold the support 36 horizontal between two planes 40, 41 and the support 36 can be rotated by means of a controlled wheel 42 by a motor 43 which also drives, by a reduction gear 44, two transport rollers 45. In the upper plane 40

  is the recording medium 46 to read and in the lower plane

  laughter 41 is the paper 47 on which must be written.

  The rotation of the reading and writing device 35 by the motor 43 establishes between the reading and writing members 37, 38 and the recording medium 46 respectively the paper 47 a relative movement with two components which is similar to that described for the example of FIG. 1. The recording medium 46 can therefore here also be explored line by line while the

  writing line by line on paper 47.

  Figures 6 and 7 each show a device

  recording system consisting of a playback device 48 which can operate

  ner independently and a writing device 49 which can also

operate independently.

  The reading device 48 comprises a cylinder 50,

  on the side surface of which the recording medium is placed

  ment 51 and inside which there is a reading device 52 which is formed of a support 53 on which are arranged reading members 54 like those described in relation to FIG. 3. The support 53 is rigidly connected to a shaft 55 located on the cylinder axis and driven by a motor 56 which also controls, by a reduction gear 57,

  a transport roller 58 cooperating with a pressure roller 59.

  The writing apparatus 49 also includes a cy-

  lindre, 60, on the lateral surface of which the paper 61 is arranged and inside which is a writing device 62 which is formed of a support 63 on which are arranged writing members 64 like those described relati . m ... ent in Figure 2. The support 63 is

  rigidly connected to a shaft 65 located on the axis of the cylinder and driving

  born by a motor 66 which also controls, by a reducer 67, a

  transport roller 68 cooperating with a pressure roller 69.

  Different solutions are possible for ensuring the synchronism of the two devices during the transmission of information, represented by luminosities, of the reading members 54

writing organs 64.

  mechanical nisation. By connecting the shaft 55 of the

  reading 48 to the shaft 65 of the writing device 49 by a coupling

  FIG. 5 illustrates an electrical synchronization using a synchronization command 71. The reading device 48 can in this case supply a synchronization signal by which the motor 66 of the writing device 49 can be controlled of such

  so that the two devices work in synchronism.

  Figure 8 shows a simple form of an assembly

  for the transmission of information represented by luminosi-

tees captured by tracers.

  The assembly consists of two parts connected to each other by a transmission system 78. The first part comprises a light wave guide 74, an optoelectric converter 75, a first amplifier 76 and a transmitter 77 and it is designated here by " reading element "72. The second part of the assembly, designated" writing element "73, comprises a receiver 79, a

  second amplifier 80 and a tracer 81.

  The luminosities received by the light waveguide

  neuses 74 are converted by the optoelectric converter 75 connected to the guide 74 into an analog electrical signal, which is

  amplified and transmitted to the transmitter 77 by the first amplifier 76.

  The transmitter transmits the signal amplified by the transmission system.

  sion 78, which may consist of a line or a radio link for example, to the receiver 79. The signal received by the latter is then amplified by the second amplifier 80 and transmitted in the form of an analog voltage signal to the tracer 81. Depending on the amplitude of the voltage, the latter burns relatively small parts or

  relatively large of the metal sheet of metallized paper.

  All the parts described above of the assembly are carried out according to conventional technique, so that

  their detailed description is not necessary.

  An even simpler arrangement can be conceived, in which the information received in the form of luminosities by the light wave guide 74 is transmitted directly to the writing element 73, which must in this case contain a converter.

  optoelectric instead of the receiver 79.

  The mechanical and electrical systems described in the foregoing allow exploration of a recording medium

  line by line at a very high speed, to transform the informa-

  tion represented by the luminosities in an electric voltage ana-

  logic and apply this tension to a writing device that makes the information read visible. It is of course possible to operate several of the devices described in parallel in order to obtain a dissolving power or a speed of exploration and

writing even higher.

  The assembly shown in Figure 9 allows a

  universal application of the recording device.

  In a simple execution, this assembly consists -

  also of a reading element 82, of a transmission system 83 and of a writing element 84. The reading element 82 comprises a light wave guide 85, an optoelectric converter 86, a first circuit of command 87, an analog-digital converter

  88, a first amplifier 89, a pulse generator of syn-

  timer 90, a transmitter 91 and, optionally, a memory 92.

  The assembly constituting the writing element 84 consists of a receiver 93, an operating circuit 94 for synchronization pulses, a second control circuit 95, an amplifier 96, a plotter 97 and, optionally, a

memory 98.

  A recording medium is explored by a light wave guide 85 and the information - brightness thus obtained is transmitted to an optoelectric converter 86 which transforms it into an analog voltage. This voltage is applied by a circuit

  command 87 to an analog-digital converter 88 which transmits it

  forms digital information, which is transmitted, amplified by the first amplifier 89 and with the synchronization pulse

  supplied by the generator 90, by the transmitter 91 and the transmission system

  mission 83 to the receiver 93 of the writing element 84. The receiver

  separates information and synchronization pulses. The last-

  nières are applied to the operating circuit 94 which influences the control circuit 95 so that it controls the second amplifier 96 so that the information available to the receiver

  93 be amplified and applied at the appropriate time in the form of an im-

voltage pulse to the plotter 97.

  Control circuits 87 and 95 can be used

  also read, if there are several light waveguides 85, 98 ...

  optoelectric converters 86, 99 ... respectively, as well as

  several plotters 97, 100 ..., to connect the opto-converter

  electric at the right time at the analog-digital converter

  that 88 and / or to have the second amplifier 96 send

  when required a voltage pulse to the desired plotter.

  It is also possible to provide a storage circuit 92, 98, reading side and / or writing side, the middle of which

  memory can be a selective access memory or a

  quette (square recording disc & deanées). In this case also, the various components of the assembly are produced according to a technique

  conventional, so a detailed description is not necessary

  to be. The invention thus creates an apparatus which offers numerous possibilities of application. Note first the possibility of using it as a copying device which, as described below, can enlarge and reduce. It can also be used

  as a fax machine. It is still possible to use it for viewing

  be a recording medium on a screen, to print a television picture or to classify recording media under

reduced form.

  Figure 10 illustrates the universal possibilities

  of communication of different parts of recording devices

  according to the invention with each other and with other devices.

  For example, as shown on the left side of FIG. 10, a reading device 101 can be linked to

  any number of writing devices 102, display screens,

  station 103 and / or storage devices 104, which can also be located in different places. The right-hand part shows that a writing device 105 can, in a similar manner, be linked to reading devices 106, display screens,

sation 107 and memories 108.

  All of the reading and writing devices respectively represented as individual devices in FIG. 10 can of course also be combined reading and writing devices, which also gives the possibility of

  directly copy a recording medium.

  Figure 11 is used to explain the possibility of reproducing a recording medium read at larger or more

Small scale.

  First of all, for the case where enlargements, reductions or reproductions on a 1: 1 scale must be produced, the reading device 117 must contain as much

  reading devices 109, 110, 111, 112 that the writing devices

  ture 118 contain reading elements 113, 114, 115, 116, the-

  which must each be formed from the same number of reading or writing elements (tracers). It is also necessary that the radius of the circle described by the reading members 109, 110, 111 and 112 during the rotation of the reading device 117 is equal to the radius of the circle described by the writing members 113, 114, 115, 116

  during the rotation of the writing device 118.

  When these conditions are satisfied, a reproduction of a recording medium on a 1: 1 scale is obtained if the angular path and the advance path S3 covered by the writing devices 113, 114, 115, 116 in a time t are equal to the angular path s2 respectively to the advance path s4 that the organs

  109, 110, 111 and 112 read at the same time t.

  According to the representation of FIG. 11, it can therefore be said that at an instant tl, the reading member 109 occupies the position A and the writing member 113 occupies the position D. At an instant t2, the member reading 109 is in position B and the writing member 113 is in position E. The two members have therefore covered the same path in the circumferential direction at the same time. As the advance path s3, s4 in the direction

  axial directly depends on the angular path s1, s2 in the direction

  radial, both with regard to the writing device,

  ture 118 that as regards the reading device 117, the advance paths are also the same for the two members 109

and 113.

  If a recording medium is to be shown enlarged, on a 1: 2 scale, for example, the writing members 113, 114, 115, 116 must cover at the same time an angular path s1 and an advance path s3 which are twice as large as those of organs

reading 109, 110, 111, 112.

  Therefore, if, in the representation according to FIG. 11, the reading member 109 occupies position A at time t1 and position B at time t2, the writing member 113, occupying the

  position D at time t1, must be at position F at ins

  both t2. The writing member 118 must therefore rotate twice as much

faster than the reading organ 117.

  At time t2, the reading member 110 occupies position A but the writing member 114 is already in position E and therefore cannot be used. This is why the information read by the member 110 is transmitted to the writing member 115 which occupies the position D at the instant t2. The four reading members 109-112 therefore supply alternately the writing members 113 and 115, the other writing members, that is to say the members 114 and 116,

are not used.

  If a recording medium is to be shown

  smaller, at a 2: 1 scale for example, the situation is reversed.

  The angular path s and the advance path s3 covered by the writing members 113, 114, 115, 116 in a time t

  must only correspond to half of the angular path s2 res-

  pectively of the advance path s4 which the organs of

  reading 109, 110, 111, 112 in time t.

  Therefore, if, according to the representation of FIG. 11, the reading member 109 occupies position A at time t1 and position C at time t2, the writing member 113 must be

  at position D at time t1 and at position E at time t2.

  The reading device 117 must therefore rotate twice as fast

as the writing device 118.

  At time t2, the writing member 114 is in position D but the reading member 110 is already in position B, so that the information read by it cannot be used. This is why the information transmitted to the writing device 14 is

  the information read by the reading member 111 which is the one found

  at position A at time t2. The reading members 109 and therefore supply the writing members 113, 114 alternately,

  115, 116, the reading members 110 and 112 not being used.

  It is therefore possible very simply, co = e demonstrated in the foregoing, by varying the speed of rotation respectively stopping writing or reading organs, to produce enlarged reproductions or on the contrary

  reduced compared to the 1: 1 scale of different recording media

  registration. The variation of the speed of rotation can be ensured by mechanical means, a gear for example, or electric means, by the variation of the speed of rotation of the

engine for example.

  Another possibility of reproducing in enlarged or reduced form a read recording medium consists in using the

  temporary storage described in relation to FIG. 9.

  In this case, one can first use a simple embodiment for enlarged reproduction; which must

  meet the same conditions as those described for the provision

  recording device of FIG. 11. It is added, however, that the reading device and the writing device must rotate

at the same angular speed.

  A 1: 2 scaling process will be

  schematically described in what follows with respect to the fi

gure 12.

  In time tl, a reading device 127 explores a recording medium 129 by its reading members 119-122.

  The luminosities received by the reading members are transformed as described for FIG. 9 into digital information which is

  introduced with the synchronization pulses into a memory 130.

  To obtain an enlargement, the stored information must be

  transmitted to the writing devices 123-126, under the command of the im-

  synchronization pulses, in a time t2 which is twice as long as the time t1. As the information memorized line by line is output at half the frequency with which it was introduced, if the rotational speeds of the reading and writing devices are equal, the writing devices must perform

  a double angular path respectively a double advance path.

  After time t2, the writing member 123 is at point D and the writing member 125 at point C. It follows that the second line read by the reading member 120 must be taken out of

  the memory to be transmitted to the writing device 125.

  The reduction of a recording medium explored,

  half the size, for example, is possible with this arrangement.

  tif if the frequency at which the information is output from the memory is twice as high as the frequency at which it had been

  introduced and if there are eight writing organs instead of four.

  Another possibility to produce enlargements or reductions of explored recording media and this in

  any format only limited by the dimensions of the device

  tif registration will be described below.

  First, the device must meet two conditions. The radius of the circle described by the reading devices of the reading device during the rotation of the device must be

  equal to the radius of the circle that the writing organs describe

  during the rotation of the writing device. Of course, it is also necessary that the number of reading elements is equal to the number of

writing elements.

  These conditions satisfied, it is possible to re-

  present a recording medium explored at the same, on a smaller or larger scale with the use of a memory

* temporary for information read and synchronization pulses

  and a control circuit which receives return pulses from a response device combined with the writing device and which also processes synchronization pulses from the memory.

  The operation of such a recording device

This will be described below.

  First, the recording medium is explored and the information - luminosities transformed as described for FIG. 9 into digital electrical information are introduced.

  with the synchronization pulses in the temporary memory.

  The output of information from this memory is controlled by two

  manners. On the one hand, depending on the enlargement or reduction-

  tion desired and the speed of rotation of the writing device, the output rate of the data from the memory is adjusted so that the information for a line can be output and transmitted to a writing device, within the limits of the path angular fixed by the format. On the other hand, the output of the information from the temporary memory must be interrupted when the plotters of a writing device receiving the information leave the paper format on which it is to be written, this interruption having to last until that the plotters of another writing device arrived at the beginning of the paper to write the next line. It goes without saying that the paper feed must also be interrupted in this

time.

  Unlike the embodiments described hitherto of the recording device, the advance device, producing the advance movement of the recording medium to be read or on which must be written, can also be constituted

  a separate motor, a stepper motor for example.

  It appears from the above and from the drawings that the recording device according to the invention constitutes an apparatus offering numerous possibilities of application. It makes it possible to quickly produce direct copies, that is to say on the same scale, but also enlarged or reduced copies. As described, the information can also be transmitted remotely to

  remote recording devices. It is also possible to memorize

  read information and print it later at the desired time and as many times as desired. However, there are still other possibilities of application. Regardless of the reading station, the recording device can also be used to reproduce in known manner texts or other images appearing

  on a display screen for example. Conversely, it is pos-

  also likely that information read by the read device

  ture are first shown on a display screen without using the printer. Such information can then be reproduced on paper with the use of all or part

  of the recording device. We obtain a very advantageous set

  geux when, also as described, reading members and writing members are arranged on a common support since this

  provides a compact package.
