A thickness filter device is for use in an insertion chute of a reader for tickets, cards or the like. The device includes a mobile assembly comprising a stirrup member in the form of a yoke pivoting about a fixed axis parallel to a flat support along which the ticket, card or the like passes and perpendicular to a direction of displacement of said ticket, card or the like along this plane and a roller mounted in the stirrup member. The roller has a support shaft parallel to the fixed shaft and mounted in the stirrup member with play so that, in the absence of any ticket, card or the like between the roller and the support plane, it allows the roller to be pressed onto this plane with a pressure calibrated by traction spring means. This play also allows the roller, under the effect of a force opposing the action of the spring means, to bear against a wall of the stirrup member linking two parallel flanges of said stirrup member forming a yoke. With no ticket, card or the like on the support plane, the plane containing the fixed shaft and the support shaft is at an acute angle .alpha. to a plane normal to the support plane and containing the fixed shaft. The plane containing the two shafts is on the same side of the normal plane as the ticket, card or the like before it is inserted into the machine. The stirrup member is additionally acted on by spring means maintaining the angle .alpha. constant provided that the only friction force on the roller is that of its shaft during its rotation, and therefore with no contact between the roller and the wall of the stirrup member.

A mechanism for inserting a flat object into a processing device for processing the object, the processing device including a fixed frame having an insertion slot via which the object is inserted, the slot forming a passage having a wall which is perpendicular to the surface of said flat object, and which serves as a reference abutment surface for one side of said flat object, the mechanism being wherein the mechanism includes two wheels, each of which penetrates into the slot via a respective aperture, at least one of the wheels being mounted at the end of a rocker arm whose other end is mounted in a cradle to pivot about a rocking axis that is parallel to the direction F in which the flat object is inserted, wherein the cradle is in turn mounted in the fixed frame to pivot about a swivel axis that is perpendicular to the plane of the insertion slot, wherein resilient elements apply a certain pressure to press the wheels together, and wherein an abutment delimits the swivelling stroke of the cradle about the swivel axis.

A card reader has a guide channel followed by a connector and it includes a cradle pivoting about a stationary axis, a roller whose axis is parallel to the stationary axis being mounted in the cradle with freedom to move in translation along a direction .increment. perpendicular to the roller axis, said direction .increment. being at an acute angle .alpha. to the direction in which the guide channel extends, the cradle including resilient return means urging the angle .alpha. to close and drive means acting on command and of greater power than said return means to urge said angle .alpha. to open. The roller includes resilient means urging it along the direction .increment. towards the vertex of the angle .alpha.. When the reader is in the rest position, the roller obstructs said channel, when a card is fully inserted in the reader, at least a portion of the card remains outside the reader, the cradle being in abutment in a position where the angle .alpha. is less than the angle .beta. whose tangent is equal to the coefficient of friction .mu. between the roller and the card. The drive means are powered after the card has been processed so as to open the angle .alpha. and enable the card to be withdrawn.
