Abstract

PROBLEM TO BE SOLVED: To prevent the breakdown of data stored in an IC card without performing such operations as the switching-off of a power supply, etc., when an IC card is mounted and dismounted. SOLUTION: When the right end (the upper end of the position shown by a dotted line) of a door 2 is pushed by a finger, etc., the door 2 turns toward an arrow A around a rotary shaft 14 and a card mounting part 3 is opened. Then the tip of a switch drive bar 16 projecting at the rear side of a rotary part 13 is removed from a switch knob 19, and the contact connection of a switch 18 is opened. Thus, the power supplied to an IC card 11 via the contact of the card 11 touching the connector contained in an IC card holder 12 is cut. As a result, the data can be protected from its breakdown that is caused by the mounting and dismounting of the card 11. The part 13 is engaged with a concave part 23 of a hinge holder 21 through a convex part 20 formed at the outer circumference of the part 13. Then the part 13 is locked.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a protection device for an IC card, and more particularly to a device for preventing data in an IC card from being destroyed by mounting or removing the IC card.

[0002]

2. Description of the Related Art In order to receive pay television broadcasts (satellite broadcasts) and the like, an IC card called a "smart card" or the like in which an identification code or the like of a subscriber has been recorded is issued. , An identification code is read, a descrambling circuit is activated to release scramble (encryption), and a pay broadcast is received. A microcomputer or the like is incorporated in the IC card, and a contact provided on the IC card is connected to a connector of the receiver or the like when mounted on the receiver or the like, and power is supplied through the connector and the contact of the receiver or the like. Then, the microcomputer is operated to read out the identification code and the like, transmit it to the descrambling circuit or the like of the receiver, and release the scramble. By the way, when an IC card is attached to or detached from a connector while power is being supplied, the stored data may be destroyed due to a shift in the timing of contact or disconnection of contacts (plurality) or chattering. is there. For this reason, a note is attached to the receiver that the IC card must be attached / detached when the power of the receiver is turned off. There is a problem that data is destroyed when a card is inserted or removed.

[0003]

SUMMARY OF THE INVENTION In view of the foregoing, the present invention detects a movement associated with an IC card insertion / removal operation and automatically stops the power supply to the IC card, thereby destroying data. Without any special operation for protection,
An object is to prevent data stored in a C card from being destroyed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an IC card protection device according to the present invention will be described below in detail with reference to the drawings. FIG. 1 is a perspective view of a main part showing an outline of an IC card protection device according to the present invention,
2 and 3 are side sectional views of a main part of an embodiment of the IC card protection device according to the present invention, and FIG. 4 is an enlarged view of a rotating portion. In FIG. 1, reference numeral 1 denotes a panel, 2 denotes a door, and an IC card mounting portion 3 is provided below the inside of the door 2, and the upper side of the door 2 is pressed inward by an upper end portion (near a “push” display), The lower part rotates outward, and the IC card mounting part 3 at the lower part inside the door.
The IC card can be inserted and removed.

In FIG. 2, 11 is an IC card, 12 is an IC
The figure shows a card holder.
Indicates a state of being closed by. Reference numeral 13 denotes a rotating portion protruding rearward from the rear surface of the door 2, reference numeral 14 denotes a rotating shaft provided on the rotating portion 13 for rotatably supporting the door 2, and reference numeral 15 denotes a door receiver for receiving the lower end of the door 2. , 16 is a switch drive piece, 17 is a switch drive piece receiving portion, 18 is a switch, 19 is a switch knob, and the switch drive piece 16 is formed to protrude backward from the rotating portion 13 and pushes the switch knob 19 with the tip. Thus, the switch 18 is maintained in a state where the contacts are connected. In the rotating portion 13, the convex portion 20 formed on the outer periphery engages with the concave portion 22 of the rotating portion receiver 21, and holds (locks) the door 2 at the position shown in the figure. As a result, power is supplied to the IC card 11 from the connector provided in the IC card holder 12 through the contacts of the IC card 11, and the IC card 11
And the like can be read. The door 2 has a door receiver 15 in contact with the lower end on the inner side, and the door 2 is received by the door receiver 15 even if the lower part of the door 2 is pressed, so that the door 2 does not come into contact with the IC card 11 and the IC card 11 or There is no risk of damaging the IC card holder 12 and the like.

FIG. 3 is a view showing a state in which the door 2 is opened. When the door 2 is pressed in the vicinity of the indication of "push", the door 2 rotates as indicated by an arrow A.
The upper end of the door 2 enters into the panel 1, the lower end rises forward, and the convex part 20 on the outer periphery of the rotating part 13 is
The door 2 is locked at this position, and the IC card 11 is inserted into the IC card mounting section 3 so that the IC card holder 12 is locked.
Or the IC card 11 mounted on the IC card holder 12 can be removed. In addition,
Further, even if an upward force is applied to the door 2, the switch driving piece 16 hits the switch driving piece receiving portion 17, and the door 2 cannot rotate any more, and the surface of the door 2 contacts the end of the panel 1. There is no fear of scratching.

When the door 2 rotates, the switch driving piece 16 also moves in the direction of the arrow B.
, The switch knob 19 is released when it is depressed, and the contact connection of the switch 18 is released.
The supply of power to the card 11 is stopped, and even if the IC card 11 is inserted or removed, the data stored in the IC card is not destroyed. Before the door 2 is rotated to an angle at which the IC card 11 can be mounted on the IC card mounting portion 3, the front end of the switch driving piece 16 is separated from the switch knob 19 so that the front end of the switch driving piece 16 is separated from the switch knob 19. And the position of the switch 18 are set.

[0010] As shown in a partially enlarged view of the rotating portion shown in FIG. 4, a hollow portion 31 is formed inside the convex portion 20 of the rotating portion 13,
When the rotation of the rotation part 13 (= the rotation of the door 2) disengages the protrusion 20 of the rotation part 13 from the recess 22 of the rotation part receiver 21, the protrusion 20 and the lightening part 31 are removed. The flesh 32 between them is bent inward due to the lightening, and the convex portion 20 is pressed against the inner periphery of the rotating portion receiver 21 by the repulsive force of the bending, thereby preventing unnecessary rotation of the door.

[0011]

As described above, according to the present invention,
According to the protection device for the C card, when the door of the IC card mounting portion is pressed to insert or remove the IC card, the door is turned, and the switch is activated by the turning of the door, thereby supplying power to the IC card. Is stopped, the data stored in the IC card is not destroyed by the insertion and removal of the IC card, and the operation such as turning off the power every time the IC card is inserted and removed is highly convenient.
