The tablet 102 has an angle (a) adjustable with respect to the plane of the keyboard 106. A second embodiment of a system according to the invention is now described with reference to FIGS. 4 to 6 which are diagrammatic representations in perspective. of this second mode. In this second embodiment, the longitudinal direction of an accessory 100 is substantially parallel to the longer side of a tablet 102. With reference to Figure 4, an accessory 100 is shown. The accessory 100 is arranged to cooperate with a tablet 102. The accessory 100 provides in a second so-called use configuration, represented in FIGS. 4 to 5, a keyboard 106 arranged on an internal face 108 of the accessory 100 and intended to be connected to the tablet 102.

The cover 104 comprises magnets 1101, 1102, 1103 arranged to interact magnetically with at least one metal part (not shown) integrated in a lateral edge of the tablet 102. The tablet 102 has an angle (a) that is adjustable with respect to the plane of the keyboard 106.

FIG. 5 contains the same elements as those described in FIG. 4 with the exception of the magnets 1101, 1102, 1103. In addition, FIG. 5 represents the use configuration which comprises a hinged stand 112 around an axis substantially parallel to the plane of the tablet. This axis is located on the opposite side of the keyboard 106. The stand 112 is provided at its end with permanent magnets (not shown) and is arranged to interact magnetically with at least one metal piece (not shown) integrated in the rear face of the tablet so that it has an angle (a) adjustable relative to the plane of the keyboard 106.

Referring to Figure 6, the accessory 100 shown comprises the articulated stand 112. The stand 112 is rotated about an axis substantially parallel to the plane of the tablet. The accessory 100 further comprises a housing 114 for partially receiving a lower portion of the tablet 102. The receiving housing 114 is placed between the keyboard (not shown) and the hinged lever 112 of the tablet and comprises at least one substantially parallel slot to the axis of rotation of the stand. This housing comprises a connector 116 for connecting the tablet 102 to the keyboard 106. The stand 112 is provided at its end permanent magnets integrated to the workpiece 118. The workpiece 118 is placed on the end of the stand 112 on the side of the The piece 118 is rotated relative to the stand 112 about an axis substantially parallel to the axis of rotation of the stand. Thus, the articulated stand 112 receives in support a portion of a rear face of the shelf 102. The shelf 102 is inclined with respect to the accessory 100. The workpiece 118 thus allows the stand to form an area of plane contact substantially parallel to the plane of the tablet 102. Finally, the stand 112 and the piece 118 are arranged so that the magnets integrated in the workpiece 118 interact magnetically with a metal part integrated in the face of the tablet 102. The articulated stand provides intermediate angular positions of the tablet 102 relative to the accessory 100. A typical use of the tablet is to position it at an angle between the tablet 102 and the accessory 100 varying between 5 and 85 degrees.

The accessory 100 also comprises a receiver housing 114. This receiving housing 114 can support a lower portion of the tablet 102. This housing also constrains the maximum angle that can take the tablet relative to the support. The connector 116 is of wired type and is integrated in the receiver housing 114. The housing 114 comprises magnets (not shown) to better hold the tablet 102 in the housing 114. Indeed these magnets exert on the tablet a force directed towards the housing. The magnetic force of these magnets is determined so that the entire accessory and the shelf remains secured when gripped by a user of the accessory or tablet by a user. The accessory 100 is thus secured to the tablet 200 by means of these magnets in addition to the first ferromagnetic connection made between the piece 118 and the metal part included in the rear face of the tablet. In addition, the magnetic force of these magnets is low enough that the user can easily separate the tablet from the accessory when it maintains in one position one of these two elements and wishes to separate the other element of the first. The receiver housing 114 further comprises an index set (not shown). The indexing of the tablet makes it possible to position the accessory in all the directions of the slot. The index set includes indexing pads (not shown). In the second embodiment of a device according to the invention, illustrated by FIGS. 4 to 6, the longitudinal direction of an accessory 100 is substantially parallel to the longer side of a tablet 102. - 9 - Referring to FIG. Figure 7, the accessory 100 shown comprises: - a support 702 of the tablet, - an articulated stand 704 extending from the support 702.

The support 702 comprises a metal crossbar (not shown) on which the articulated stand 704 is rotatably mounted with the support around an axis of C. The axis C forms an angle f3 with a perpendicular to a direction substantially parallel to the shelf . The angle p typically has a value substantially equal to 5 °. This angle is typically between 0 ° and 45 °. In addition, the articulated stand 704 comprises a workpiece 706. Magnets are integrated in the workpiece 706. The articulated stand 704 and the workpiece 706 are rotatably mounted about an axis D. The support 702 also comprises an internal housing 708. This internal housing 708 allows to receive in support a lower portion of a tablet. This housing also makes it possible to constrain the maximum angle that can take the tablet relative to the support. We will now describe a third embodiment, only for its differences with the two previous modes. In this third embodiment, the indexing of the tablet is performed by magnetization rather than by the implementation of indexing pads. Thus, the index set includes permanent magnets for interacting magnetically with permanent magnets located in the connectors of the tablet. These embodiments being in no way limitative, it will be possible to imagine variants of the invention comprising only a selection of characteristics described subsequently isolated from the other characteristics described, if this selection of characteristics is sufficient to confer a technical advantage or to to differentiate the invention from the state of the prior art. This selection comprises at least one preferably functional feature without structural details, or with only a portion of the structural details if it is that portion only that is sufficient to confer a technical advantage or to differentiate the invention from the invention. state of the art.
