However, in such a conventional manual IC card (hereinafter simply referred to as a card) attaching / detaching device, the extracting operation can be performed even during signal input / output in the card memory. , The memory contents may be destroyed. Also, if the card is stolen, there is a risk of data leakage. Moreover, in order to attach and detach the card to and from the connector, it is necessary to apply a large force to the card, but the card is not provided with a concave portion or a convex portion as a clue on the outer shape.
Therefore, when the card is attached to the connector, it is necessary to push the card later. Therefore, depending on the manual operation, the force required for removing the card increases due to the unfavorable bias of the force as the number of times of attaching and detaching the card increases, and finally an unexpected situation occurs. SUMMARY OF THE INVENTION It is an object of the present invention to provide a device for electrically attaching / detaching a card to / from a connector having a two-layer structure with a small size, a light weight, and a simple structure at low cost.

[0005]

In order to solve the above-mentioned problems, an electric card attaching / detaching device according to the present invention is a device for attaching / detaching a card to / from a card reading / writing device. A card holder that is slidable on the card holder and has a support protrusion that abuts against the insertion-side edge of the inserted card, and a holding means that holds the card; Card insertion arm, a slider that is slidable in the moving direction of the card and that engages with the insertion arm, a drive cam that engages with the card holder and the slider, and an electric drive member that controls the drive cam. It consists of and.

The insertion arms are provided on both sides of the moving path of the card, are pivotally supported by a rotating shaft perpendicular to the surface of the moving path, and are rotatable, and an axis parallel to the rotating shaft is provided. A rotatable roller is provided at the center to engage with the card. The card holder is provided with a leaf spring as a card holding means so that the card is held by being projected into the card holder.

Further, the drive cam has a rotary shaft on one side of the moving path, and rotates by engaging a tooth type formed on the other side with a pinion driven electrically. Then, the rotating shaft and the rotating shaft of the pinion are arranged symmetrically on both sides of the center line of the moving path in the central portion of the device. A connector having a two-layer structure is provided in the read / write device, and a rotary shaft of a drive cam related to one connector and a rotary shaft of a pinion related to the other connector are coaxially arranged with respect to each of the connectors. I set it up.

Further, the card holder is provided with a collation projecting piece which can be fitted in an erroneous insertion preventing groove provided at a tip end portion of the card on the upstream side of the supporting projecting piece in the insertion direction of the card. A normal insertion detecting means is provided which is activated when the erroneous insertion prevention groove of the card fitted in the holder and the matching projection piece are established and the end edge of the insertion side of the card comes into contact with the bearing projection piece. It is suitable. This normal insertion detecting means is a switch that is interlocked with an operating arm that is pivotally supported coaxially with the pivot shaft of the drive cam. More preferably, the collating protrusion of the card holder, which can be fitted in the erroneous insertion preventing groove provided at the tip of the card, may be used as the card supporting member when the card is ejected. In a device for inserting and removing a card with a mis-insertion prevention groove to a general card read / write device, it can be fitted into the card support member at the time of card ejection and the mis-insertion prevention groove provided at the tip of the card It is more preferable to use it as a matching member.

In this structure, the card holder holds the card by the holding means when the card is inserted from the insertion / removal opening and the end edge of the insertion side is brought into contact with the bearing protrusion of the card holder for positioning. , The card can be slid toward the connector in the read / write device, and the card can be pulled out from the connector while being supported by the support projections and moved in the ejection direction.

The card insertion arm rotatably arranged near the insertion / removal opening of the card applies a driving force directly to the trailing edge of the inserted card to push the card toward the connector. The slider that engages with the insertion arm is slidable in the moving direction of the card, and rotates the insertion arm to engage the rear edge of the card and apply a driving force that pushes the card toward the connector. In addition, the insertion arm is rotated in the opposite direction to release the engagement with the card and move to a position where it does not interfere with the movement of the card. Furthermore, the drive cam is controlled by an electric drive member,
Such a card holder and slider are interlocked in a predetermined order.

The insertion arms are provided on both sides of the moving path of the card to uniformly bias the card from both sides, thereby avoiding the bias of the insertion force. Further, by pivotally supporting the insertion arm by the rotation axis perpendicular to the surface of the movement path, the rotation surface of the insertion arm can be set in the same plane as the movement path, and the engagement is performed along the rear edge of the card. be able to. And,
Since the roller rotatable around an axis parallel to the rotation axis is engaged with the card trailing edge, the engagement is smoothly performed and a sufficient operation force can be applied.

The card inserted in the card holder receives lateral pressure by a leaf spring provided so as to project into the card holder, and the card is held by a contact frictional force generated between the card and the card holder. However, this frictional force is extremely small as compared with the acting force for coupling the card and the connector, so that the card cannot be fitted into the connector by moving the card holder.

Further, the drive cam has a rotation shaft on one side of the moving path, and a tooth mold formed on the other side is rotated by meshing with a toothed pinion driven electrically. The planar structure of the plate member allows the drive system to be provided on one side of the card, and the rotating shaft and the rotating shaft of the pinion are symmetrically arranged on both sides of the center line of the moving path in the central portion of the device. For each of the arranged two-layered connectors, the rotation shaft of the drive cam and the rotation shaft of the pinion are arranged coaxially with each other, and the individual attachment / detachment devices in two stages are compactly configured. You can

Further, in the case where the front and back of the card or the front and back are mistakenly inserted, it is possible to prevent the card from entering by the collating protrusion provided on the card holder, and the card inserted in a normal posture can be prevented. Since only the verification protrusion fits in the erroneous insertion prevention groove, the insertion-side edge of the card reaches the normal insertion detection means without bearing, and the operation arm is rotated to operate the switch. As a result, the initial conditions of the electric attachment / detachment device according to the present invention can be satisfied.

Generally, in a device for attaching and detaching a card having an erroneous insertion prevention groove, a matching member that can be fitted into the erroneous insertion prevention groove is provided in the card discharge member, and this matching member is used when the card is discharged. Can function as a support member of the.
