The invention is to be explained in more detail below using an exemplary embodiment. In the Drawing shows

Fig. 1 is a side view of the device,

F i g. 2 shows a detail from FIG. 1 with a switch tongue a contact lever in the switched state, FIG. 3 a part of the side view according to FIG. 1, Fi g. 4 a circuit diagram for a plug-in card.

In Fig. 1 a rear and front Vorsteckkarle 1, 2 are shown, which are between below a platen 3 arranged transport rollers 4; 5 and card pressure rollers 6; 7 are located. The further description in the following refers only to the one assigned to the plug-in card 1 Execution, as this is built analogously to that of the plug-in card 2.

The Karienandruckrollehebel 26 (Fig. 3) is just-o like the KartenandruckroHenhebel 25 articulated with toggle levers 30 and 29, which in turn are articulated to an axis 31 pivotable toggle levers 33 and 32 respectively. Furthermore, step levers 35 and 34 are articulated on the toggle levers 33 and 32, respectively, on which tension springs 37 and 36 act. The step levers 35 and 34 are given away with angles 39 and 38, which are actuated by magnets M

Control lever 41 or 40 are in contact. The stepped levers 35 and 34 are provided with control lugs 43 and 42, which, depending on the position of the Stufer.hebe ¹ 35 or 34, lie in the area of an angle 44 which is associated with a card slot holder 46 pivotable about an axis 45. The card slot lever 46 carries a card slot funnel, not shown.

In the ^ Fig. 3 takers, the toggle lever 30; 29 and 33; 32 against the force of tension springs 48; 47 a bent position in relation to one another, whereby the card

pinch roller lever 26; 25 are in their extreme counterclockwise position and thus the card pressure rollers 7; 6 of the transport rollers 5; 4 are lifted.

Every contact that is perpendicular to the feed direction

lever 11 is available in multiple arrangements,

wherein the contact levers 11 are parallel to one another are aligned with the lower edge of the pre-installed card.

The switch tongues 9 are therefore equipped with switches S ₁ . S.,

and .S ', provided (Fig. 4), the switches S ₁ . S ₁

and the switches. *>. ,, S., are each switched one after the other. The common line leads via an RcLis R I to the other pole of the voltage source. A contact r _M is in the circuit of the magnet M, while a contact r _{l2 is} in the circuit

of a relay R 2. Relay.R 2 has a self-holding contact r.,., and a contact r. _{) p} which lies in series with a feed motor Mo and the contact; · ,,.

The operation of the device is described below.

When inserting the pre-installed card 1, the card slot lever 46 is located with its not shown Card slot funnel in the position after

Fig. 3. where the angle 44 over the step lever 34 and the corresponding toggle levers 29; 32 the Kartenandruckhebcl 25 in its open position has convicted.

The index card fills the switching tongues 9 of the contact levers 11 and automatically aligns itself on the alignment surfaces 12 of the alignment levers 13 in the horizontal direction, the switching tongues 9 covering the switching path s and assuming the position shown in FIG. Depending on the position and the width of the plug-in card, the switches S ₁ and S ₃ or the switches S ₃ and S ₂ or the switches S ₁ ; S ₂ and S ₃ actuated, which close the circuit for the relay R 1. The contact r _n switches and the magnet M assigned to the plug-in card 1 is excited. The magnet M actuates the control lever 40, which pivots the stepped lever 34 in a clockwise direction, the toggle levers 29 and 32 assuming a mutually extended position due to the tension spring 47. The Kartenandruckrollehebcl 25 and the shaft 23 move clockwise and secure the aligned position of the Vorsteckkartc 1, the release lever 21 via the lever 15, the contact and alignment lever 11 and 13 analogous to the position shown in Fig. 3 for the execution for the plug-in card 2 is pivoted out of the catchment area of the Vdr plug-in card 1.

ίο The switch tongues 9 now return to their original position, with the relay Rl dropping out . The contacts r _n and r ₁₂ again take the position according to FIG. 4 a. The relay R 2, which was previously excited via the actuated contact r ₁₂ , remains due to the self-

The contact r _{i2 was} still energized, so that the feed motor Mo can start up via the contacts r _u and r _{21 connected in series} and the plug-in card 1 can be drawn in.
