- the introducer 1 illustrated in Figure 1 is removably mounted on a printer 2 of which only part of the frame 3, the transport rollers 4, the transport shaft 5 and the drive motor 58 are represented.
- the device 1 may of course also be attached to the printer, a typewriter or any other device using flat materials, such as than sheets of paper, card stock, or envelopes.
- the device 1 comprises a magazine 6 with a bottom 8 (fig. 2A), one front wall 9, two side walls fixed 10 and 11, and a support plate 12 on which a pile 14 of sheets, envelopes or all other flat materials may be arranged.
- the support plate 12 is pivotally articulated on the side walls 10, 11 by means of two pivots 15 engaged in longitudinal openings 17 allowing a adjustment transverse to the axis of the pivots 15.
- Three springs 16 urge the support plate 12 towards the drive rollers 20 mounted on a drive shaft 23.
- This support plate 12 has a lateral guide mobile 25 for the sheets slidably mounted on the support plate 12 in a perpendicular direction to the direction of introduction of the sheets indicated by arrow 26.
- the guide 25 serves as a lateral support allowing the proper introduction of all flat materials, sheets or envelopes, of different sizes.
- the width of the introducer can thus be adapted to different formats of flat materials to introduce.
- the support plate 12 is further subdivided in its lower half into three parts 27, 28, 29 separated by slots 30 and 31, each part being stressed individually by one of the springs 16 towards a drive rollers 20.
- each part 27, 28, 29 can be moved relative to neighboring parts. So, we obtains a substantially identical application force from material to be introduced against the drive rollers 20 therefore a regular displacement of the material to be introduced for any width and thickness of this material.
- the rear face of the bottom 8 of magazine 6 is provided with an auxiliary sheet support 34 retractable intended to serve as support for the upper part large leaves.

- the button head 37 has a larger diameter than the width of the slot 38, the plate 35 is retained against the rear face of the bottom 8, but can slide along a direction parallel to slot 38 along a part in projection 40 provided on the rear face of the bottom 8.
- the anterior wall 9 of the store has an inclined plane 45 making an angle predetermined ⁇ with a plane 46 parallel to the lower part of the bottom 8 of the store.
- This angle is preferably chosen between 50 and 85 ° and very advantageously between 60 and 80 °. It is in the configuration illustrated in Figure 2A equal to 71 °.
- the inclination of this plane 45 relative to the rear part of the front wall 9 is therefore located between 5 and 40 ° and is in Figure 2 equal to 19 °.
- the inclined plane 45 includes three recesses 47 in which are bonded three strips 48 of a material to fibrils, such as a velvet-like tissue.
- the depth of the recesses 47 is such that the upper part fibrils of the strips 48 appear above the surface upper of the inclined plane 45 so as to cooperate with the anterior edge of sheets or flat materials to introduce and retain these materials including the anterior edge penetrates between the fibrils of the bands to constitute retainers.
- These bands 48 have a resistance to movement of a sheet which is a function the material of the fibrils used, their diameter, of their length, their density and the depth of penetration of the anterior edge of the leaf. Tapes 5 mm wide with a density of 18,000 fibrils / cm2 1.5 mm in length gives excellent restraint effect, when these fibrils exceed 0.5 mm the upper surface of the inclined plane 45.
- the fibrillated strips 48 are embedded in the inclined plane 45 in positions located next to the drive rollers 20.
- the most the top of the stack is moved away from the fibrils ( Figure 2B), while the following sheet and the others are held in place by the fibrils of the bands 48 without the need for retaining corners lateral, as is the case in the majority of known introducers.

- the advancement mechanism 54 includes a cam 85 secured to the drive shaft 23 and having two projecting sectors 86.87.
- a advancement lever 88 is pivotally mounted on magazine 6 and biased by a spring 89 against the cam 85.
- the spring 89 is mounted between the free end of the advancement lever 88 and the magazine 6.
- the cam 85 is arranged so as to stress the drive shaft 23 in rotation in the clockwise direction in FIG. 3A, when the drive shaft is in a position such that either of the scalloped sectors 63.64 of the indented pinion 62 is opposite the second pinion 61 and that the notched pinion 62 is therefore not driven by the second pinion 61, but blocked by the locking lever 66.
- the drive rollers 20 are cam-shaped and have three sectors.
- a first sector 100 has a coefficient high enough friction to separate and the highest leaf drive of the stack of sheets, a second sector 101 with a coefficient of friction low enough to allow the sliding of this sheet during an alignment phase when introduced into the printer and a third sector 102 offering clearance for loading leaves.
- the high coefficient of friction sector 100 consists of a central elastomer coating 109 applied to a support 105 bordered by two cams 103 in plastic with lower coefficient of friction constituting the second and third sectors 101 and 102. Sectional view, the exterior surface of the covering made of elastomer 109 exceeds the cams 103 of plastic material over a sector of approximately 180 ° to enter contact with the highest leaf ( Figure 2B).
- cams 103 exceed coatings made of elastomer 109 to come into contact with the leaf.
- cams 103 are flattened to form said clearance and the elastomer coating 109 occupies a position of withdrawal.
- the drive shaft 23 still includes six surfaces circulars 104 with a radius equal to or less than the smallest radius of the drive rollers 20. These circular surfaces 104 are intended for guiding the sheets between the transport rollers.
- the drive shaft 23 is integral with each of its sides of an actuating cam 106 intended to cooperate with two lateral extensions 107 of the support plate 12 to push the latter back into the leaf rest and loading position (figure 2A).
- the drive shaft 23 is made of injected plastic and comes from a part with cams 103, with supports 105 (fig. 2A) for the elastomer coating 109, with the six surfaces guide circulars 104, with the two cams actuator 106 to push back the support plate 12 and with the advancement cam 85 divided into two cams parallel.
- This shaft 23 is guided in two bearings 108 (fig 1) of the magazine 6 and secured to the notched pinion 62.
- the actuating cam 106 cooperates with the plate support 12 to push it back.
- a stack of 14 sheets can be loaded in tray 6. Sheets are retained at their anterior edge by the retaining strips 48 with fibrils.
- Cams 103 with low coefficient of friction drive rollers 20 are separated from the sheet the higher.
- the protruding sector 86 of the advancement cam 85 ( Figure 3A) cooperates with the advancement lever 88, which requests the drive shaft 23 according to a direction of dextral rotation.
- the drive shaft 23 is however held stationary by lever 66 ( Figures 4 and 5) whose tooth 68 is inserted into the opening 70 provided in the skirt 71.
- the tooth 68 of the lever 66 actually stops against the left edge 110 of this opening 70 and retains the drive shaft 23 against the action exerted by the advancement lever 88 on advancement cam 85.
- the first notch 63 of the notched pinion 62 is in look of the second pinion 61.
- the motor 58 of the printer is rotated according to the opposite direction to the paper advance.
- Sprockets 60 and 61 then rotate in a dextrous direction so that the straight strand 94 of the clutch spring 92 (fig. 4) comes into contact with the end 75 of the lever 67.
- this spring 92 are tightened by a rotation dexter of the shaft 93 on which they are wound, the straight strand moves the lever 67 in a rotation senestre around the pivot 74, and the lever 67 drives lever 66 via the lateral extension 76 in its senestrial rotation movement.
- the meshing of the notched pinion 62 with the second pinion 61 is performed adequately due to the elasticity radial toothing of the notched pinion in the vicinity of the clutch wheel thanks to the opening 65a provided under the teeth.
- the motor 58 is then rotated in the direction of rotation corresponding to the progress of the transport of leaf.
- Gables 60 and 61 rotate in a senestral direction and the notched pinion 62 and the drive shaft in a dextrous sense.
- the cam projections 106 are released from the support plate 12 and the stack of sheets 14 is applied by the springs 16 against the drive rollers 20.
- the sector to high friction coefficient 100 of the elastomer coating 109 comes into contact with the highest leaf from stack 14 and release this sheet from the retaining bands 48 to fibrils, while the other underlying leaves remain retained.
- the selected sheet is then taken between the transport rollers 4 of the printer turning in the direction of transport advancement of sheet.
- the sector 101 with a lower coefficient of friction cam 103 contacts the uppermost sheet which is then no longer advanced by the drive rollers 20 (fig. 2C).
- the second indented sector 64 of the pinion indented 62 is opposite the second pinion 61, while that the projecting sector 87 of the advancement cam 85 cooperates with the advancing lever 88 to turn the drive shaft 23 in a dextrous direction to the Figure 3C.
- the tooth 68 of the lever 66 enters under the effect of the spring 72 in the opening 69 of the skirt 71 of the indented pinion 62, so that the rotation of the pinion indented 62 is stopped since tooth 68 comes into abutment against the edge 111 of the opening 69.
- This transport behind the selected sheet is made possible by the low coefficient of friction of the sector 101 of the drive rollers 20.
- the selected sheet is taken obliquely between the rollers transport 4 of the printer, it is aligned perfectly by the reverse transport movement.
- the motor 58 is put into operation. rotation in the direction of leaf transport, the tree 23 is rotated dexter. In reference in FIGS. 2C and 2A, the actuation cam 106 pushes back the support plate 12 behind to move the stack away from sheets 14 of the drive rollers 20, while the selected sheet is advanced by the rollers of transport 4 of the printer.
- the indented sector 63 of the wheel notched 62 arrives opposite the second pinion 61 and the tooth 68 of lever 66 falls under the effect of spring 72 in the opening 70 of the skirt 71.
- the drive shaft 23 is at this moment solicited in dextral rotation by the action advancement lever 88 on the projecting sector 86 of the advancement cam 85 so that the tooth 68 of the lever 66 is pressed against the edge 110 of the opening 70 of the skirt 71. This position therefore again corresponds to the initial rest position during which the impression of the selected sheet is performed.
- This construction of the introduction device allows very reliable operation of the separation of the highest leaf, while having a number of weak components, and can therefore be manufactured at very low cost price.
- the strips of fibrillated material 48 provide excellent restraint to sheets stacked in tray 6, while allowing easy separation from the highest sheet.
