• the control unit 64 therefore has in memory the "tops" of passage, the durations of passage and the coordinates of the panels to be passed.
• the display of panel A is provided. Consequently, the electromagnet 38 of the jack 36 A, that is to say of the jack arranged opposite the tongue A, is supplied so that the plunger acting as a support protrudes from the body of the jack 36 and the plunger passes through the hole 58 of the tongue 56 A.
• the control unit 64 then controls the starting of the motorization so as to put in rotation of the pulleys 44 which themselves drive the toothed belt 48, which itself drives the support strip 42 on which the jacks 36 are attached.
• the poster to is therefore extracted from the reserve 54 and the tongue, mounted loosely in relation to the panel, is trained and curve so as to follow the profile of the strip 42 in closed loop, the tongue being pressed and held by the interior of the strip 22, so that the tongue does not "jump" from the end of the plunger of the gripping means 32 .
• the end of the plunger head is slightly flattened so as to give it a blocking power.
• the semi-rigid panel bends in turn and follows the profile of the strip 42 and as soon as the panel begins to descend into the display window 12, it is pressed against the transparent outer protective wall 26 by the springs of the plating elements 50.
• the control unit stops the motorization, so that the face of the panel bearing the information is perfectly positioned in the display window 12.
• control unit again supplies the motorization to cause the panel f "to be gripped by a second series of jacks 36, and simultaneously the panel £ is returned to its initial position.
• the tongue is held by the strip 24 on the gripping means 32, the tongue being, after its rotation, held by gravity, the panel exerting downwards its own weight.
• the panel When the panel is at the right of the reserve, taking into account the inclination of the frame, the lower part the panel is housed in the reserve. It then suffices to excite the electromagnet of the jack 36 so that the tongue is detached from the gripping means 32. The panel, of sufficient rigidity, is pressed against the panel C remaining in the reserve. During this phase, the panel B has been placed to the right of the display window 12 and it remains for the programmed duration.
• the control unit thus causes the display of the various panels at the different times and for the established durations.
• the user can also change display panels almost instantly. It suffices for this to prepare a cassette and to put in the memory 60 the necessary information, then to substitute the second cassette for the first, the information transmitted to the control unit by the first cassette being erased and replaced by the information contained in the memory 60 of the second cassette.
• the cassette has no memory and the control unit 64 is connected either by a radio link or by cable to a control station which can be a program previously introduced into a microcomputer.
• control unit is then directly linked to the pre-established sequence in the microcomputer, which makes it possible to modify, in real time, the order of passage of the panels, or quite simply the duration of passage.
