Description

The present invention relates to the marketing of printed articles: newspapers, articles, magazines, books, comic strips, etc., hereinafter referred to by the generic term "publication". corresponding to an object printed in several copies, for example an issue of a magazine, no. of a periodical, or a specific edition of a book. By "exemplary" is meant an unfair product corresponding to a publication, for example a magazine issue or an edition of a book. The terms "article" and "exemplary" are used equivalently in the following. The present invention also relates to a distribution network of copies of a publication with the possibility of recovery, as well as to a method of implementing the distribution and the resumption of copies of printed publications, in particular press , through such network. The invention also relates to a point of sale station used by such a network. The sale of copies of press publications is largely done to date via point-of-sale networks, usually in the form of a single sale with a fixed price over a fixed period imposed by the periodicity of the sale. each publication. The international application W02005 / 073932 relates to an automated press distribution kiosk comprising a display and a dispensing receptacle for giving access to a user to a chosen copy, using a robotic arm. This sales model encounters a certain number of difficulties, particularly with regard to its logistical costs (capillary distribution at each point of sale, logistics for the return of unsold goods, etc.) and a large consumption of paper, including for a significant percentage. drawn numbers not distributed or sold. Application US2011245965 discloses a sales deposit system enabling the man of the street to offer for sale multimedia products, such as books, music CDs, DVD movies and electronic games, using to characterize the articles put in Indistinctly selling the common SKU for each range of articles deposited or the ISBN for all books of the same edition. The method described does not make it possible to separately manage several copies, or even a large number of copies, of the same publication. It is also known for loan libraries to have automated loan and return machines. The effective utilization rate of a copy remains low in duration of use (reading) and in number of readers per copy. There is a need to limit waste in the area of printed publications (piles of copies piled up at the publisher's or the buyer-reader's home). There is a need to improve the ecological and economic balance sheet of the dissemination of printed publications. Subscription distribution, based on a pre-subscription and home delivery, allows the publisher to better assess the quantity of copies to be printed. However, this offer is sometimes unsuitable in the face of the emergence of new consumer habits (purchase coup de coeur, variable frequency consumption, purchase discovery, "fluttering" buyers / readers). There is a need to improve the subscription offer.

In addition, the press and magazine offer is very rich, but the spectrum of consumption per reader remains low. "There is a need to broaden the reading possibilities of each consumer. led to offer a new alternative press service to the publication printed on paper The switch from the written press 20 to digital is booming.This digital model imposes a suitable reading medium (tablet, computer, smartphone ...) for However, the use of such an electronic medium imposes significant purchase cost and its ease of use in any place is not always acquired.In particular there are problems of restriction of technical order (network accessibility, autonomy) 25 which reduce the possibility and / or the approval of the service.In addition, these digital equipments are expensive and their use in public space can be hindered by security issues and the risk of theft. For the reader, the paper copy, inexpensive in comparison, does not present this type of problem. In addition, the visual, tactile and reading experience are not the same between a digital reading and the stripping of a paper copy. A good proportion of readers remain attached to the comfort of a paper reading, even though they are strong consumers in digital.

There is a need for a printed paper offer complementary to the digital offering. The invention aims to meet all or part of these needs. According to a first aspect, the subject of the invention is a method of taking back at least one copy of a printed publication, using at least one point-of-sale station, the method comprising the following steps: a. reading an identification device, in particular in the form of an RFID device or CAB tag, and identification of the copy, b. calculation and / or offer, in particular by posting, a price for the copy, c. taking the copy for storage. The invention makes it possible to change the traditional sales model of press point networks or libraries in order to offer the possibility of unitarily taking back the copies once read and putting them back into the distribution circuit for a new operation. sale. The invention offers the possibility of a new use based on p. age and mobility. The invention thus makes it possible to establish a new model of collaborative commerce between the various actors of the supplychain of press publications (publishers, courier companies, press depositories, wholesalers, press broadcasters, libraries, networks ....) through a new service. Thanks to the invention, the customers have the possibility of recovering part of the cost of the initial purchase according to the decided usage. For a customer the service offered is more open and less engaging than a purchase outright and the invention thus widens the possible field of readings. The invention makes it possible to reduce the number of copies in circulation for an identical perimeter of readers, and thus to reduce the costs of production and distribution. In particular, the invention makes it possible, on the basis of a network of sales outlets geographically distributed, to provide a service that fits naturally with the available time given, for example, for a trip or trip waiting for a station, an airport, public transport, train, ...) with the purchase of a copy at the start of a journey, reading during the waiting and the trip, recovery of the copy on arrival.

The method according to the invention can also be implemented in all the waiting places (halls, hospitals, administrations, ...), or more generally as a service available to a community (company, association). The invention advantageously makes it possible to manage several publications and several copies of the same publication. The invention thus advantageously makes it possible to manage a copy of a publication during several reading cycles, the number of reading cycles being limited only by the state of use of the copy and the readers' interest in the publication. Thus, the prolongation of the commercialization of a periodical beyond its usual range, after the issue of the following number (s), is possible if the demand from the readers is still strong. The invention thus makes it possible to evolve the current sales model towards new and more open formulas. The invention makes it possible both to broadcast as many copies as possible and also to increase the number of rotations of a copy in order to create a new issue for the readers. For publishers, the invention leads to an increase in the number of customers and an increase in the profitability per copy compared to a single sale (reduction of production costs and logistics costs of a copy, reduction in the number of copies published and potential increase in gain per copy due to 20 multiple rotations). By "storage" within the meaning of the invention means any storage of the copy for a longer or shorter period. The storage can take place in the station or externally to the station, for example in a shopping system as described later especially for a subsequent resale or possibly a possible scrapping. Each point of sale station is arranged to manage at least the recovery of a copy. The point of sale station may belong to a distribution network. By distribution network, means within the meaning of the invention a set of 30 points of sale.

Each copy is connected to a unique identifier associated with the identification device. The method of the invention makes it possible to separately manage each copy from several copies of the same publication. The identification device may comprise a CAB tag or an electronic device, in particular an RFID device with or without contact. The identification device can be fixed by any means to the copy. In particular, it can be printed directly on the copy or be glued in particular on the front or back side of the cover or inside the copy. In a variant, the identification device is incorporated before the assembly of the copy, at the time of manufacture of the pages of the copy in a page, for example a cover page or an additional page. The method may further associate with the copy at least one parameter related to. the corresponding publication, in particular: a reference purchase price nine, a publication date, a periodicity, a maximum number of read cycles accepted, the time stamp 15 of the start of sale of the next publication, the remaining duration before the next publication, the collection period allowed between two successive publications, the timestamp of the end of the publication's commercialization, the period before the end of the publication's commercialization, the wording of the publication, its ISBN or ISSN or a commercial reference at the publisher, a language, this list being non-limiting. 20 "Reading cycle" means a rotation of the copy starting with the purchase of the copy by a user at a first point of sale, the period during which the copy is held by the user, called indifferently "reading time" or "period of detention", then the recovery of the copy in a second point of sale station, different or not from the first point of sale. The terms "client", "reader" or "user" are used indifferently to designate any user of all or part of the process. Similarly, the term "purchase" refers to any transaction in which a customer obtains an unlimited copy or not. The method may relate to a complete reading cycle and include a step of purchasing the copy.

The parameter (s) associated with the corresponding 1.ion may be external data to the station or network, for example the publication date or the reference new purchase price which may correspond to a public selling price. A parameter of the copy, in particular related to the publication, can correspond to a datum of reference and remain fixed. The parameters related to the publication may comprise at least one reference digital representation corresponding in particular to the front and / or back side, a nominal format, a nominal thickness, or even several nominal thicknesses measured at different places of the publication, a nominal weight. This list is not exhaustive.

The invention is not limited to a number of referenced publications or to a number of copies of the same publication. In an exemplary implementation, a parameter of the copy linked to the publication corresponds to a maximum authorized number of copies put into circulation with a recovery option. A publication-related copy parameter may be a number of copies actually released with a rollback option. Publication related parameters may be stored on an extemalized database and made locally available to each point-of-sale station, for example on demand, particularly at the time of each take-back or purchase.

In a variant, the parameters related to the device are stored at least in part in a database of each point of sale station. The parameters related to the publication are for example updated regularly from the database extemalised to a database of the point of sale station, for example weekly or daily especially at a fixed time, or regularly several times per week. day. By circulation history, we mean all the operations concerning a copy, in particular purchase and recovery. The method may furthermore associate with the copy at least one parameter related to its circulation history, chosen from: a new purchase price, a resale price, an updated purchase price, a circulation time stamp. , a first purchase time stamp, a time stamp of the last purchase, a cumulative reading time, a reading time since the last purchase, usage status, a cycle number, a purchasing point of purchase station, a point station resale sale, the timestamp of a resumption or purchase transaction, this list being non-limiting. These parameters can be at least partially updated at each recovery and / or purchase operation.

"New purchase price" exemplary means the purchase price corresponding to the first purchase of said copy by any reader using the method of the invention. "Recovery price" means, for one copy, the calculated price to be offered to the customer for decision. By "state of use" is meant, for a copy, the physical state of the copy evaluated by the station. A parameter related to the circulation history of the copy can be initialized during a preparatory step, for example the use state corresponding to a new reference state. A parameter related to the circulation history of the copy can be initialized during a reading cycle, for example the new purchase price at the time of the first purchase, or the recovery price at the time of the first requested recovery. A parameter related to the history of the copy can remain fixed after initialization, for example the new purchase price after the first purchase. A parameter related to the history of the copy can be recalculated at each reading cycle, for example the resale price, the discounted purchase price. At least one of the parameters can be calculated by a processor of the station or network, including the recovery price, the discounted purchase price. The method may include the calculation of the new purchase price, the latter may be higher than a public selling price and have an additional cost in order to integrate the flexibility induced by the possibility of recovery with unique identification of the copy. In a variant for the particular case of a subscriber player, the purchase price, new or discounted, may include a reduction granted to subscribers. Preferably, the method associates with the copy at least one use state and a recovery price, at the time of taking over the copy, the use state being evaluated and used to calculate the recovery price, as it is specified later. Preferably, at the time of the recovery of a copy is calculated its purchase price for the next reading cycle.

Alternatively, the purchase price is calculated at the time of a purchase transaction, as detailed below. These parameters related to the copy are for example stored in a central database and can be, at least in part, made available to each station 5 point of sale especially at the time of each recovery operation or purchase. In a variant, the identification device comprises a rewritable memory which is for example stored all or part of the parameters related to the copy and / or the corresponding publication. The method may include updating the memory of the identification device of the copy. The method may include an evaluation of the state of use of the copy to be taken back. The state of use of the copy being evaluated for example in the station, in particular s. an airlock of the station. This evaluation can be done automatically. In a variant, the evaluation is semi-automatic. The state of use of the copy may be, at least in part, diagnosed in particular visually by a staff of the point-of-sale station. During a cycle, the price of the copy may, at least in part, depend on the result of the evaluation. The valuation can be used to determine the trade-in price and / or purchase price of the copy for the next cycle. The result of the evaluation can, at least in part, determine the place of storage and / or presentation of the copies in a point of sale, for example in the form of storage in a unitary storage location or in an unloading rack arranged for a storage in number of copies as detailed further away. The storage location is for example located in a particular rack of the point of sale station, or even a shopping system as described below. In one variant, the recovery price and / or the discounted purchase price per copy are defined and are not calculated at each cycle. The method of the invention may include a price calculation system using at least one of the parameters attached to a copy, no. to the corresponding publication, and its circulation history, as seen above.

These parameters can be used to adjust the purchase price and / or recovery of a copy, which advantageously allows to meet the specific needs of different actors in the distribution chain. The price of recovery and / or purchase of the copy can be calculated according to a set of rules and rates set centrally. The recovery and / or purchase price calculation system may use parameters other than those defined previously, for example a customer identifier, one or more pricing scales, in particular depending on the duration notably related to a publication, one or more several pricing schedule (s).

The recovery and / or purchase price calculation system can thus combine different pricing rules. The trade-in price at the end of a reading cycle can be used to calculate the discounted purchase price at the beginning of the next reading cycle. The recovery price and / or the discounted purchase price can be calculated by a more or less complex algorithm depending on the parameters of the copy. The method may comprise a pricing system, in particular in unitary form and / or in the form of a subscription. The subscription system may be known to those skilled in the art associating in particular each subscriber customer subscription identifier.

The setting data of the subscription system and / or the charging system can be stored locally and / or centralized. The method may include initializing and updating the copy database, pricing rules, and / or the subscription system. The method may comprise reading a device for identifying a user, particularly a subscribed user, in particular in the form of a subscription card. In one variant, the method takes into account additional information related to the subscribed user, in particular chosen from among the subscriber's cumulative data, such as the number of operations made by the subscriber on one or more period (s). time, the degree of fidelity and use of the service, the number of hits per type of publication, the total length of reading over a period of time, the number of possible copies held concurrently, the credit authorized or purchased by period and associated units, this list being non-limiting. The method may include updating a memory of the identification device of a particular user subscriber.

The method may comprise a preliminary step of preparing the copy for no. to associate an identifier with the copy, to make and / or fix the identification device to the copy as described above. This preparation step may be, at least partly, centralized, being implemented for example for a given number of copies. The parameters of the copy linked to the publication are for example centrally recorded and made available locally. During the preparation step of the copy, the strength of the copy can be improved in particular by plasticizing the covers. The identification device is for example fixed at the time of L-plasticizing the copy between a protective layer and the cover.

The step of preparing the copy may include, at least in part, the manufacture of the copy and / or its identification device, for example in the form of printing a CAB label or the programming of an RFID device. In a variant, the step of preparing the copy includes the use of editing materials adapted to increase the wear resistance of the copy and its potential for reuse. At the time of the preparation step, the method may include verifying maximum number of copies for a publication not reached. This step can be implemented during the first purchase or the supply of the stock of a station.

At the time of the recovery, or the loading of the initial stock in particular during the preparation stage, the processor of the station can verify, either directly or by interrogating the central system, that a maximum authorized number of copies for a publication is not reached. The parameters of the copy linked to the publication and / or history of the copy can be initialized when referencing the publication and / or one or more copies during the preparation stage.

In a variant - preparation of the copy is carried out locally by a point of sale station, the parameters of the copy linked to the publication are for example recorded directly locally. Station According to another aspect, the invention relates to a point of sale station, arranged to implement a method according to the invention of taking over at least one copy of a printed publication, the station comprising at least one of means for evaluating the state of use of the copy and a price calculation system, for calculating a rework price and / or a purchase price paid for the copy.

The station according to the invention can be automatic. The station can be semi-automatic. The station requests, for example, the intervention of a staff. In a variant, the point-of-sale station can be autonomous. Preferably, the station is connected to a remote central control system. The station can be part of a network or even several networks. The point of sale station comprises a device for reading the identification device of the copy. The point of sale station may include a device for reading a user identification device, including subscriber.

In a variant, the station comprises a read / write device arranged to update a memory of the identification device of the copy. The point-of-sale station comprises a user interface comprising for example, in a manner known to those skilled in the art, a screen, in particular a touchscreen, possibly a keyboard ... intended to propose a purchase and recovery price, and according to the variants visualization of publications and / or copies available for selection. The station is not linked to a given language and may include the choice of a display language for the one of several users. The station may include means for evaluating the state of use of the copy.

The station is for example arranged to allow the referencing of new copy.

The state of use of the copy can be evaluated automatically by the evaluation means of the point of sale station or diagnosed, in particular visually, by personnel including the point of sale. The evaluation means may comprise an optical system for performing image processing. The optical system may comprise at least one optical sensor, in particular a camera or a scanner, for acquiring at least one 2D or 3D image, black and white or color, intended to be. This is done by image processing by a station processor or a central system.

The image processing can use a method known to those skilled in the art, including a method adapted to a real-time control, such as methods with an EQM-based approach, or a structural approach, IQM, UQI, MSE, SNR, PSNR, VS Q, SSIM, MSSIM, M-DFT, MD M-DCT, PQS, SVH, or a neural approach, or a combination of several of these methods, this list being f limitative. The evaluation means can thus make it possible to measure the degradation of a copy, for example on all or part of its cover and on the slices, in particular on the areas subject to greater degradation (corners, edges, etc.). ). The degradations encountered are particularly of the type: chipped, tainted, folded or having traces of folds, torn, damaged, scratched, scribbled, curled, stapled, taped .... Image processing (in particular for that slices) can also use edge detection methods to identify the level of deformation in relation to the nominal size and the nominal thickness of the copy, especially on the corners and edges. The distortion can then be measured as deviations from the reference data. Similarly, the weight measurement makes it possible to measure the deviation from the reference weight of the copy, with a tolerance for example taking into account an acceptable intake of humidity that weighs down. Each of the tests (images processed on the front, each slice, weighed, 30 leaves, other ....) can give rise to a unit scoring, whose means of evaluation make the synthesis, to obtain an overall evaluation of the state of use by combination and weighting of the different tests according to predetermined rules and calibrations. By way of example, the final overall result of the evaluation of the copy corresponds to a level with respect to a scale (for example A = new state, 13 = correct state, C = used state, HS = state damaged and non-marketable). In a variant, the evaluation means directly use the measurements 5 carried out without comparing to reference values, it is verified, for example, whether the thickness is constant along the slices without using a reference thickness. Preferably the usage state evaluation means comprise at least one optical sensor for the front face, the two upper and lower slices of the copy, and the edge opposite to the binding. When the method includes an evaluation of the state of use of the copy, a process administrator can initialize or update all the methods, instructions and parameters to be used during the evaluation of each copy, specifying, for example, the tolerances allowed in the measurements and the comparative calculations in relation to the reference values. In one variant, the evaluation means of the state of use of a station are used, for example during the preparation step, to determine at least one reference parameter linked to the particular copy or to the corresponding publication. The point of sale station may include an insertion service arranged to receive the copy. The insertion service may include an insertion mechanism designed in such a way as to facilitate for the customer a determined positioning of the exemplary, in particular in a predefined orientation, and its engagement in the station. The station may comprise a door, for example transparent, to prevent access to the insertion service and / or to an airlock of the station during evaluation and / or control operations. The door is for example blocked during the implementation of the steps of evaluation and / or control of the process. Preferably, the door is unlocked only to allow the insertion of a copy. Preferably, the station is arranged to also manage the purchase of the copy, as detailed below. The station may include a price calculation system for calculating a discount price and / or discounted purchase price of the copy.

The recovery price and / or the discounted purchase price of the copy is for example calculated at p of at least one parameter related to the publication or circulation history of said copy, on p. from at least the state of use as evaluated. The station may include the recording of each unit purchase or delivery operation, either locally or on the central system. The invention can be implemented by adapting points of sale or an existing network. The method of the invention can coexist with a conventional sales system, no ent interfacing with him. A station of the invention can thus be arranged to offer the choice between a method according to the invention - as described above and a conventional method of final sale to the number. The invention can thus generate an increase in traffic to existing outlets, favorable to all products and services offered there. A point-of-sale station of the invention can also integrate a set of services or ancillary operations, for example commercial and advertising advertisements, distribution of commercial coupons, lottery, participation in paid games. The station may comprise an electronic processor including a memory. The processor is in particular configured to evaluate the state of use of the copy, calculate the recovery and purchase prices, exchange data with the central system, manage the interface with the customers.

The station may include a payment terminal. For example, the payment terminal comprises at least one payment method chosen from a coin mechanism, a bill reader, a contactless mobile phone payment terminal, a credit card reader, a subscription card reader, a means of payment. reading / writing of an "electronic purse" in the form of a key, card or other, an identification reader of a customer account, this list being non-limiting. The payment terminal may also be associated with a keypad for entering a code or any other means of authentication known to those skilled in the art. The price can be calculated and / or presented to the user in several currencies. The payment terminal can accept one or more currencies.

The station may include a printing module, in particular for editing an invoice.

The station may have multiple individual storage locations to store multiple copies of the same publication or different publications. The station processor can drive a station-specific shopping system.

The shopping system may be external to the station. The station may include means for moving the copies, for example a motorized belt, a presence sensor, a robot, a mechanical driving system, or any other known means of displacement. The station may comprise one or more means of presentation of at least one of the copies by available publication, in particular physical presentation means (transparent window), and / or digital no. in the form of a catalog which can be consulted on screen, allowing the customer to make his choice. The point-of-sale station according to the invention can no. It includes all the features known to those skilled in the art of a station, in particular automatic, distribution and sale of copies of press publications, books or magazines. According to another of its aspects, the subject of the invention is a method of adapting a dispensing station for press organs at a point of sale according to the invention. Warehouse System The station may have an integrated warehousing system or be connected to an outdoor shopping system. The shopping system can be dedicated to a station, or connected to several stations. The shopping system may be external to the station. An external shopping allows the station to accept and store a larger number of copies (up to several thousand) and to isolate and facilitate the logistic movements of loading and unloading the copies in a dedicated space so that they are not visible and disturbing for the customers and can be carried out by the operating personnel in safety vis-à-vis them (no cross logistic flows, with mobile racks, and customer flows). This formula is particularly suitable for intensive use, several stations with shared shopping. The shopping system may include a shopping management system configured to exchange information with the station processor.

The shopping system includes a storage space arranged to house the copies and handling means to ensure the movement of entry and exit of a copy of the storage space, including from or to a station point of sale.

The storage space may include storage locations, in particular individualized, in particular shelving. The storage space may include one or more loading racks, and / or one or more unloading racks. The handling means may be of any type known to those skilled in the art. The handling means comprise for example a mobile transfer platform, guided on rails, in particular on several axes (length, height, width ...), and electric motors. The handling means allow access to each location of the designated storage space to store or retrieve a copy. The locations of the storage space may be unitary or not. In a preferred embodiment, the handling means handle unit trays each housing a copy of a publication. The handling means may comprise robotic shuttles and / or robotized and piloted manipulator arms, allowing the handling of the copies from the station or the storage space to the transfer platform and vice versa. The transfer platform may comprise a reader arranged to read the identification device of the copy machine, which facilitates the automatic registration of copies and the updating of a shopping database and allows quick access to locations or racks of storage space. The storage space may comprise at least one loading rack and / or at least one unloading rack. Said racks being in particular removable (s) and / or recessed (s) and / or mobile (s). By "loading rack" is meant a place of storage, in particular temporary, perme. t the system automatically feeds the shopping locations with one or more copies, including new copies or copies from other point-of-sale locations. The loading rack makes it possible to prepare the marketing of new copies and to balance the load of the stations. By "unloading rack" is meant a bulk storage location for storing one or more copies from the point-of-sale station (s) attached to the store for storage for recirculation. later or to be withdrawn from the sale. The storage space may include at least one loading and unloading rack, used for both functions. Said racks are intended to facilitate the logistics operations of each point of sale station. They allow to ensure an intensive and continuous operation of the stations, by carrying out the loading and / or unloading of a station with a minimum of disruption and interruption of service for the users. The copies on an unloading rack can be sorted according to their state of use which facilitates their sale or deactivation. Preferably, the racks have foldable handles, facilitating their handling and reducing the space required for the storage enclosure. The warehousing system preferably comprises a warehouse control system, in particular an automatic piloting system which controls the handling means. In the case of a multi station common storage system, the store control system ensures movement between each station and the storage space. The warehousing system comprises, for example, an automatic storage of the copies in an unloading rack, in particular organized in the form of several stacks, for example with a choice of criteria for forming the stacks, and displaying the criteria of each stack on the rack. The shopping system may also include the automatic removal of the storage space of one or more copy (s) on criteria such as the exceeding of the sell-by date or on the declaration of stop of the sale thereof , and automatically bulk 30 on an unloading rack copies concerned. The store control system may include one or more functions among the identification of each copy, its storage space in the storage space, in particular its racking, or its automatic transfer from the storage space to the station that l ordered. The store control system may also include at least one additional function, for example an automatic inventory of copies in shelving, the sanitization of copies or other. During a purchase operation, the processor can offer the customer a choice of available copies, for example in the form of a catalog display, and then identifies the location of the copy chosen by the customer. In one alternative, the processor provides the client with a choice of available publications and identifies the location of a copy of the publication chosen by the client. The copy thus selected is then brought by moving means to the distribution service. In a variant, at the time of purchase, the user indicates a forecast reading time, a point of sale or a forecast geographic area. These parameters make it possible to manage station inventories more efficiently. When a copy is taken over, the processor identifies a free slot in the storage space of the shopping system. The copy is then moved by moving means to that location. Alternatively, if no location is available, the copy is brought to a stack of the unloading rack. If the storage space is fully full, the recovery operation can be closed to users. Each station or storage system may furthermore use an inventory management system known to those skilled in the art regularly sending an update to the station processor or to the central control system. In another aspect, the invention relates to a distribution network and to the implementation of a method as described above.

The subject of the invention is also a distribution network for printed publications comprising several point-of-sale stations according to the invention and a central control system. Stations in a network may be identical.

In a variant, the stations of a network are different. A network may thus include one or more point-of-sale stations with integrated shopping as described above, as well as one or more point-of-sale stations connected to external shopping in common with several stations. In an exemplary embodiment the network comprises at least one distribution station arranged to implement only purchase operations. Such a station may be close to a point of sale of the invention providing the recovery of copy, with which it p. .ge eg a shopping system. If one of the stations is unable to perform an operation (recovery or purchase) it can for example check if the operation is possible on another station in the network and report it to the user. According to a variant, the user can interrogate the network in general or network and / or a particular point of sale and / or a given geographical area or point to know the station or stations where it can benefit from a service of purchasing a publication and / or taking back a copy. Similarly he can interrogate a station in 20 p. to know if it can have a publication or make a copy. This service can be accessed by a terminal of any type known to those skilled in the art (computer, tablet, smartphone ...), or directly on the screen of a station. The publication-related copy settings may include information about the network (s) authorized for the recovery. The copy preparation phase can be implemented using the central control system. According to yet another aspect, the subject of the invention is a set of several distribution networks and recovery of printed publications connected together. As seen more Mut, a copy bought in a first point of sale 30 can be made in the same point of sale or second outlet different from the first.

The second point of sale may belong to a network different from that of the first point of sale. The central control system can be common to several networks. The central control system may comprise several computer systems, in particular communicating with each other. The central control system, by having information of all purchase operations and recovery of circulating copies, advantageously ensures a balance between the point of sale stations. The network may be linked to a circuit, in particular a separate circuit, for recycling used copies so that the stations / points of sale can accept returns of old copies regardless of their state of use. DESCRIPTION OF THE FIGURES The invention will be better understood on reading the following detailed description of examples of implementation of the invention and on examining the appended drawing, in which: FIG. An example of a printed publication that can be integrated into a process according to the invention is shown in FIG. 2, which shows diagrammatically several examples of retail outlet stations according to the invention connected to a shopping system. FIG. 4A to 4D illustrate, in partial section along IV-IV, the point of sale station of FIG. FIG. 5 is a block diagram representation of a copy recovery operation by a method according to the invention, and FIG. 6 illustrates in block diagram an exemplary exemplary operation step according to a method of FIG. inv and FIG. 7 represents an example of several distribution and resumption networks according to the invention.

FIG. 1 represents a copy 1 of a printed publication comprising an identification device 2, for example in the form of an RFID device or CAB tag, which is associated with a unique identifier of copy I. In the example illustrated, the device of FIG. identification 2 is attached to the back side 4 of the exemplary 1. The identification device 2 can be attached differently, in particular on the front face 3 or on the edge of the copy on the binding side 5 without leaving the door. In a variant, the identification device 2 is fixed inside the example, for example it is incorporated in the cover or any of the pages of the copy. has several identification devices associated, separately or globally, with a single copy identifier.When the copy 1 is new and except manufacturing defect, its dimensions, in particular the height h, the la 1, and the thicknesses e5 of the edge edge 5 and e6 of the side edge 6 opposite, correspond to characteristic reference values, H, L, E5 and E6 of the publication 10. Similarly, the front faces 3 and verso 4 of the copy 1 as well as the edge of the copy binding side 5 correspond to the front sides 13 and verso 14 and the wafer side 15 of the publication 10. These parameters H, L, E5, E6 , 13, 14, 15, as well as the nominal weight P, linked to the publication 10 are for example stored in a centralized database of a central control system 600 and / or in a memory 65 of a processor 60 a point of sale station 100 as shown in FIG. 2. The central system 600 may be remote and for example connected by wireless connection, in particular via the Internet, or by wire connection or any other means known to the skilled person. at one or more point (s) of sale.

Figure 2 schematically shows two point of sale stations 100 of the invention connected to a shopping system 400, the invention is not limited to a number of stations connected to the same shopping system. In the illustrated example, each station 100 includes an insertion service 30.

Displacement means 20 allow the exemplary 1 to pass from the insertion service 30 to a storage system 400. In the event of abandonment of the recovery, the copy 1 is directed by the moving means 20 towards a delivery service 35, in particular separate from the insertion service 30. In a variant that is not illustrated, the insertion service is confused with the delivery service. The storage system 400 includes handling means 470 and a storage space 480, said storage space including in particular storage locations 488, including unitary locations, as well as a loading rack 482 and an unloading rack. 485. The invention is not limited to single storage locations, or to a particular number of racks. The handling means 470 comprise, for example, a robot for ensuring the input and output movements of the copy between the storage space 480 and the point-of-sale stations 100. The shopping system 400 furthermore comprises a control system store 460 for controlling the handling means 470 and a user interface 430, for example in the form of a screen. In the case of a multi-station 100 common storage system as illustrated, the store control system 460 controls the movements between each station 100 and the storage space 480. Each point of sale station 100 includes a processor 60 including arranged to, during a recovery operation, calculate and indicate the recovery price, update the parameters related to the copy. During a recovery operation, the processor 60 can evaluate the usage state of the copy 1, from data it receives from evaluation means 50 of the use state. The evaluation means 50 of the station 100 may comprise, as illustrated by the weighing system 51, for example in the form of an electronic balance, a system, particularly a robotic, page-taking system 53 for turning the pages of the copy 25 and checking the non-bonding or stapling the sheets together and / or an optical analysis system 55 comprising in particular or more optical sensors, cameras and / or scanners. In a variant, the optical sensor (s) comprises (s) integrated software performs at least one p .. e of the image processing. Each station 100 comprises at least one user interface 36 comprising for example a particular touch screen, an alphanumeric keyboard or a large format display.

As illustrated, the station - may also include payment means 90 which may be any of those known to those skilled in the art. The station comprises for example one or more payment means selected from coin mechanism, a ticket reader, a contactless payment terminal, for example for payment by mobile phone, an electronic module reader with contact. Means of payment can be configured to accept payment by credit card and / or subscription card. The means of payment may also be associated with a keypad for entering a code or any other authentication means known to those skilled in the art.

FIG. 3 represents the front face of an example of a point-of-sale station 100 connected to an own outsourced warehouse system 400, for example with a mat 39 separating the station and the shopping. In a variant not illustrated, the storage system can be internalized at the station, in solidarity with the same frame. The illustrated station 100 rests for example on a foot 80 and has an insertion service 30 having a slot no. ent horizontal and a delivery service 35 compo. t inclined plane as well as a printing module 95 and payment means 90. The station 100 and / or the storage system 400 are for example arranged to communicate, in particular by wireless connection, with a central control system 600 not shown. The invention is not limited to the illustrated example. The station may have several feet, for example adjustable, or none. In a variant, the station is placed on a piece of furniture. As illustrated in Figure 4A, when the copy 1 is deposited in the insertion service 30 its identification device 2 passes near a reader 40 to allow its identification. If the reader 40 can not read the identification device 2 of the copy 1, for example the result of the reading does not correspond to the expected format, or if the copy is not correctly positioned, the recovery is canceled. A refusal message of the operation is for example transmitted to the user via an interface 36, for example by display on a screen 32 to ask the user to remove the copy 1.

When the article is correctly positioned in the insertion service and the identification device of the copy 1 is recognized, moving means 20 are activated and direct the copy 1 to a chamber 33. If the processor 60 or the remote central control system 600 can not associate the copy to a listed identifier, or if the recovery operation of the identified copy is not accepted on this station, the recovery is canceled, a refusal message the operation is for example transmitted to the user via an interface 36, for example on a screen 32, and the copy 1 is evacuated to the delivery service 35.

The processor 60 of the station 100 retrieves from the central system 600 or in its memory 65 at least a portion of the parameters related to the copy 1 and / or the corresponding publication 10 in order to locally calculate the recovery price to be displayed. to offer it to the customer. In a variant, a part of the recovery price calculation is carried out by the central system 600, or the price calculation is totally performed by the central system which sends the price to the station for display. When the calculation is carried out by the central system, it can previously receive from the processor of the station the value of the use state. The display of the recovery price may be accompanied by the display of at least 20 part of the parameters linked to the copy, received from the central control system and / or available locally, in the form of explanatory information. useful to the customer. The method comprises for example the display of the state of use, the date and place of the previous purchase transaction and the holding period. In a variant, the user can choose a display language and / or a currency different from the default one (s) of the station, between several possible ones. In an alternative embodiment, the station comprises a clock and the processor 60 checks, for example by querying the central control system 600, the feasibility of the recovery operation according to the date and time of the reading of the device. identification of the copy. The feasibility of an operation may depend on the date and time. Generally, the feasibility of an operation may depend on the value of a parameter of the copy, for example language or other.

The displacement means 20 include for example one or more presence sensors 31 located in particular in the insertion service 30 and / or the airlock 33 to help the correct positioning of the copy 1, a motorized belt 25 especially between the service d insertion 30 and the lock 33 and a tilting tray 28 to deliver the copy in the delivery service 35. The copy 1 positioned in the airlock 33 as shown in Figure 4B is subject to a valuation of its state of use in order to calculate using the processor 60 and / or the central processor 600 a resumption price to propose to the customer and to decide whether or not the station 100 and the customer accept the recovery. of the copy L The evaluation of the state of use can also make it possible to detect possible frauds. The evaluation of the state of use is preferably performed by the processor 60 from results given by the usage state evaluation means 50, and the parameters of the copy given by the central system. 600 and / or the memory processor 60. The evaluation means of the state of use 50 include in particular optical analysis system 55 comprising for example a camera 56 and a lighting device 58 for taking pictures of the front face 3 and two scanners 57 for acquiring images of the edges on the binding side 5, and opposite side 6 of the copy 1. The invention is not limited to a number or type of optical sensor 20 particular. In a variant, the station comprises a sensor for acquiring an image of the back side 4 and / or the upper and lower slices of the copy 1. The station may comprise a scanner for each of the four slices. The means for evaluating the state of use comprise, for example, positioning and adjustment means for making it possible to approach the sensors of the copy and to adjust them precisely in order to ensure the acquisition of the images in the best conditions. . In particular, the visualization scanners of the slices of the copy include a slider, not shown, arranged to be lowered and adjusted closer to each slice and after taking the image, to be raised in height. The optical analysis system 55 captures a set of images for analysis by image processing using the processor 60.

This one checks for example in the first place, from at least one image compared to a reference image, for example an image acquired by the camera 56 compared to the front face 13 of the publication 10, that the copy 1 filed corresponds to publication 10 recognized in the intended direction.

If the presence sensors 31 or the optical analysis system 55 detect an anomaly in the position of the copy, the recovery operation is canceled, the copy 1 is returned and the user is then invited to submit the copy 1 in the correct position and orientation. In a variant, the insertion service 30 or the airlock 33 comprises an insertion mechanism to control that the copy 1 is deposited in the desired position, in the example: presentation on the front, edge on the binding side 5 on the left, without bias. The invention is not limited to the definition of a particular positioning. Alternatively, the correct positioning of the copy can be tested and / or provided automatically. For example, the positioning sensors detect that the binding 5 is entirely plated on the left side along the edge of the insertion mechanism, and is simultaneously in continuous abutment on a door 32 of the chamber 33. After proper positioning, the copy 1 is measured with the aid of the presence sensors 31, camera 56 and scanner 57. The height h, the width 1 and the thicknesses e5 of the edge on the binding side 5 and e6 of the opposite side edge 6 of the example 1 are for example calculated and compared to the characteristic reference values, H, L, E5 and E6 of the publication 10. Preferably, the height h, the width 1 and the thicknesses are calculated in several places of the copy, from the acquisition of 'picture. The image processing also makes it possible to compare the images captured by the optical sensors, cameras 56 and scanner 57, with the reference images, rectos 13 and verso 14 and, as well as the edge on the binding side 15, of the publication 10. In a alternatively, the weight of the exemplary 1 is further measured by weighing system 51. In a preferred variant, at least one image of the copy 1 taken is stored in the memory 65 of the processor 60 of the station, in order to to be displayed later to a user, or for remote intervention of personnel operating the station.

The means for evaluating the state of use are not limited to the means illustrated and may include any other means known to those skilled in the art. Measurements made using the usage state evaluation means make it possible to detect the potential deviations from the reference parameters of the copy corresponding to the publication. The image processing and / or weighing can be implemented locally using the processor 60 of the station 1. The evaluation of the state of use is preferably performed by the processor 60. In a variant the processor 60 sends the data acquired by the evaluation means to the system 600 which calculates the usage state. In a preferred variant, the central control system 600 performs a pe of the recovery price calculation, in particular from a calculation grid according to the state of use and sends the result to the processor 60 which ends the calculation of the price. of recovery, for example by applying the grid received in the state of use evaluated locally, for display and proposal of the price of recovery to the customer. The processor 60 for example advantageously displays the recovery price with the discount applied to it related to the degradation of the copy, that is to say the difference between the usage state previously stored as a parameter associated with the copy and the state of use as evaluated. A calculation grid according to the state of use is understood to mean a method of calculating the proposed take-over price as a function, inter alia, of the potential state of use of the copy made as evaluated, ie ie its new state and its evolution with respect to the value of the current state of use as previously memorized. For example: If current state = A; if new state = A, price = Pa; if new state = B, price - Pb, if new state = C, price = Pc, if new state = HS, price - Phs.

If current state = B; if new state = B, price = P'b, if new state = C, price = P'c, if new state = HS, price = Ph's etc ... In the illustrated example, the station includes a gate 32 for secure the access lock 33. The door can also help the positioning of the copy 1. The door is unlocked only when the conditions for a new insertion are met. For example, inserting another copy before the end of a current operation is not possible.

In another variant not illustrated, the copy 1 comprises i. 2 rewritable identification device and the station comprises writing means for updating the identification device during a purchase or a recovery, the identification device being in particular updated while the The exemplary embodiment is positioned on the delivery service 35 or in the airlock 33. In the illustrated example, these steps, as described below with reference to FIG. 5, are carried out by the processor 60 of the station 100 and comprise in particular the update of a memory 65 of the processor 60. The copy I leaves the lock 33 to the storage system 400 using a motorized belt 25. The shopping system 400 includes, as illustrated, a storage space 480, arranged to house the copies, and handling means 470 having a motorized transfer platform 420, movable on rails 425, vertical as illustrated and / or horizontal. FIG. 4C represents several copies 1 stored in storage unit locations 488 of the storage system 400. The recovery method according to the invention may comprise, for example as illustrated in FIG. 5, a waiting animation 300 of the The standby animation 300 proposes, for example, the clients to perform a recovery operation, a purchase, or even other related operations, for example linked to lottery type actions, or to information advertising, explanatory, or commercial offers. The user indicates at step 301 that he wishes to propose a copy 1 at the resumption. In one variant, the recovery method begins automatically when presence sensors 31 of the insertion service 30 detect that an example 1 is placed on the insertion service 30 as illustrated in FIG. 3. In step 202, once a copy 1 placed in the insertion service 30 of the station 100, the identification device 2 of the copy 1 is read by the reader 40. Preferably, as seen above, the station is arranged to exchange information with a central control system 600 and in step 202, the processor 60 of the station 100 sends the identifier read by the reader 40 to the central control system 600. The processor 60 of the station 100, in thus interrogating the central system 600 and / or locally, finds the parameters associated with the copy 1 and / or the corresponding publication 10. The processor 60 receives for example the return price grid according to the state of use, as calculated centrally. The processor 60 can also record in a memory 65 and / or transmit to the central control system 600 other information. In an alternative embodiment, the station comprises a clock and the processor 60 sends the system 600 the date and time of the reading of the identification device 2 of the copy 1, an identifier of the station, number or other, to decide on the feasibility of the recovery operation. If a problem is detected, the processor 60 signals it to the user, (step 2011) for example by displaying a message on the screen 36, with the explanatory information from the central control system 600 and / or locally of the processor 60. According to the identified defects (identification of the copy 1 impossible, copy 1 identified but can not be resumed because corresponding to a publication 10 not supported by the point of sale station 100 or the network 500, for example the 15 dimensioning of the copy 1 not accepted, position or orientation of the incorrect copy, presumption of fraud, lack of space in the shopping system), information is communicated to the customer indicating the problem as well as instructions. The customer is invited either to withdraw the copy 1 directly, if it is still accessible, or to recover the copy in the delivery service 35, to which it is evacuated by the moving means 20. The recovery is then canceled. In step 203, the evaluation means 50 check the usage status of the copy 1. A recovery price of the copy 1 is calculated at the step 204, then proposed to the client at the step 206. As mentioned above, the resale price is calculated taking into account the state of use of the copy as well as its length of possession and the other parameters of copy 1 or the corresponding publication. . The station 100 asks the user whether he accepts the calculated recovery price. If the user refuses the resale price thus proposed, he is invited to take copy 1 back into delivery service 35, as illustrated in FIG. 4D. The door 32 of the airlock 33, when it exists, is for example locked in the steps 202 to 206 and unlocked 1 (- <sc, - all the conditions are met for a new insertion (correct positioning, correct identification format in a particular embodiment, the processor 60 of the station then asks if the client wants to perform another recovery before being credited with the first operation. other occasions to be performed, or that the station can not accept another recovery, in particular if the shopping system is full, the credit transaction is made in step 207, for example by credit on a bank account or via a subscription system or via a coin mechanism.

Step 207 may include updating the data stored in a memory of a client identification device, in particular a subscriber client. The copy 1 taken again is then moved to step 208 to be stored in a shopping system 400, the latter may be internal or external to the station, in particular common to several stations as described above.

In step 209, the recovery operation is done and the parameters related to copy 1 as previously defined are updated. Step 209 may include updating the memory 65 of the station and / or a centralized database of the central control system 600. The use state and the recovery price associated with the copy For example, they are updated and saved.

In a variant, step 209 comprises writing data to a memory of the identification device 2 of the copy 1. The step 209 may comprise a display and / or an impression of a summary of the operations with the information explanatory for the customer. Following the completion of step 209, or after dropping the resume operation in step 210, the station 100 is ready for a new resume or ach it operation. Preferentially LI station i also allows the purchase of a copy 1. As shown in Figure 6, once the user, during step 301, has selected the choice of a purchase of a copy of a publication, the station management system, at step 302, can guide it in its choice of a publication 10 or a copy 1. For example, the station system allows the user to select a desired copy 1 or publication 10 from the copies 1 available in stock, in particular of a given value of one or more parameter (s) of the copy, for example use state, language or other . The present invention is not limited to the above criteria, nor to the publications and copies available in the shopping of the station. The present invention may show a copy or a reference representation of the publication, in the form of a searchable digital catalog allowing the customer to make his choice. This choice is made in step 302, for example from the consultation of a digital catalog presenting digital images of the front and / or back faces 13 and 14 of the publications 10 or with the aid of a single scrolling list. The catalog indicates, for example, the available state (s) of use (s) according to the corresponding available copies (1) and / or the associated purchase price, or the associated purchase price range. For example, the customer is required to select a specific copy. In an exemplary embodiment, if multiple copies are possible for a publication / usage-price choice choice, the selection of the supplied copy is made by the processor of the station. In a variant, the client can view the representation (s) of the available copies 1, from those stored during the evaluation of the state of use on the resumption, and so select the copy 1 Optionally, the step 302 comprises for a customer, in particular a subscriber, the possibility of identifying himself, for example by giving a username and password or by reading a device. 'identification. Preferably, when taking the copy for storage in a recovery process, the purchase price is calculated for a future purchase transaction. When loading the station by taking a copy for storage out of recovery operation, preferentially, the processor 60 of the station 100 requests the central system to determine the purchase price of said copy. The purchase price received by the processor 60 of the station is stored in the memory 65 of the station. Thus, the purchase price of the copies accompanies the presentation of the digital catalog 30 to the users of the station.

The discounted purchase price of the copy can be subject to updates, either automatically, for example cyclically, or on a particular event such as the identification of a customer or a request from a flight crew. In an exemplary embodiment, the customer identifies himself for a purchase transaction and the purchase price is recalculated so as to be personalized according to the customer. The discounted purchase price of a copy may be calculated taking into account the state of use of the copy as well as the other parameters of copy 1 and / or the corresponding publication. The calculation of the purchase price can take into account the customer, in particular of his quality of subscriber or not. In a variant, the customer first chooses a copy whose discounted purchase price is then calculated and presented. In a variant, the customer first chooses a publication whose discounted purchase price of the associated copies in stock is then calculated and presented. Alternatively, the price calculation is performed at least in part by the processor of station 100. For example, when a purchase follows a trade-in for the same customer, a discount may be granted, and the purchase price may be be adjusted locally to reflect this. During a step 304, the client indicates his selection or abandons the operation. After this validation in step 304, the station asks the customer if he wants to make another purchase, otherwise it is directed to the payment or to the end of the process.

In a variant, the station asks the user for a predicted reading time of the copy. During step 308, the customer makes his payment either by means of his subscription or by another means of payment for example as described above. The parameters related to copy 1 as defined previously are updated. The copy (s) selected (s) are then routed (s) from the shopping system by means of travel, until the delivery service 35, this in step 309. The customer is asked to recover (es) copy (s) 1 in the delivery service 35 as illustrated in FIG. 4D. In order to better preserve the condition of each copy, the delivery can be made copy by copy.

Optionally, the station gives the opportunity to the user to refuse the purchase after checking the status of the copy. For example, the customer has a few minutes to return the copy; in this case, the purchase transaction is canceled. The delivery process continues until the delivery of all 5 copies ordered. The station may optionally display a summary of the operations performed during the sequence and optionally print it as part of step 309. The network 500 illustrated in FIG. 7 comprises a central control system 10 600 as well as several point-of-sale stations 100 for purchase a and takeover transactions r. The network 500 comprises both stations 100 which are connected to an outsourced warehouse system 400 and several self-service stations 100 with an internalized shopping. The central control system 600 is for example common to the networks 500 and 500 '. In the illustrated example, the purchase and the return of the copies 1 of all the copies corresponding to the publication 10 can be done indifferently on the points of sale of the networks 500 and 500 '. For another publication 10 ', the purchase and the recovery can be done only on the point of sale stations 100' of the network 500 '20 The points of sale of each network 500 and 500' can be distributed geographically. As shown in the example, a point-of-sale station may be common to the networks 500 and 500 'or belong to only one of the networks. The method according to the invention makes it possible to manage several networks simultaneously, each having their own geographical coverage and a number of publications and copies in circulation. These networks can coexist in an interoperable way, with exchange of copies between them, or exclusively. The feasibility of an operation for a copy may depend on the date and time and / or station and network. The invention is not limited to the embodiments which have just been described.

In particular the invention is not limited to particular payment means or to a user interface as shown. The interface comprises for example an alphanumeric keyboard, a large format display. The expression "having one" shall be understood as being synonymous with "compo t at least one" unless the contrary is specified.
