Abstract

PURPOSE:To prevent the multifunction part of an IC card from being pressed by a roller by installing the roller to be frictionally contacting with the ends of the IC card in a main body. CONSTITUTION:When an operator inserts the IC card 15 into an insertion slit 12, a first detector 38 detects the head of the IC card 15 and makes a motor 16 normally rotate. By the normal rotation of the motor 16 the roller 13 is made to drive to rotate through a belt 23 and by transmitting the friction of the roller 13 an idle roller 14 starts to rotate to arrange a card lead-in condition. When the IC card is inserted more, the both ends of the IC card distant from an electronic desk calculator which has the multifunction part are held between the roller 13 and the idle roller 14 and frictionally contacted with them so as to be taken in the inside. And the contact terminal of the IC card transferred in a specified position is contacted with a contact member 30 to be set in the device. Thus, the IC card 15 can be prevented from pressing its keyboard part and its display part.

Furthermore, in the future, it is conceivable to develop an IC card having a multi-functional section with functions other than conventional IC cards, for example, as shown in FIG. 10, an IC card with a calculator provided with an affl on the IC card. This calculator-equipped IC card 15 is provided with a key 41, a display section 42, and a solar cell section 43 on its surface. This multifunctional IC card 15 is inserted into an IC card reading/writing device to transmit and receive data.

Therefore, in order to send and receive data, it is necessary to bring the contact terminals 44 of the IC card 15 into contact with the contact members of this device. To do this, the IC card 15 is moved to a predetermined position and the contact terminals 44 are contacted. The parts are in contact. In this device, in order to transfer the IC card 15, a configuration can be considered in which the IC card 15 is held between a pair of rollers and brought into contact with the rollers, and the rollers are rotated by a motor to be transferred.

(Problem to be Solved by the Invention) However, if a multi-open IC card is to be transferred by being held in frictional contact by a pair of rows as described above, in order to make this frictional contact, the IC card 15 must be must be pressed down with a pair of row arms. Therefore, if a pair of rollers is configured to press the center portion of the IC card 15, this IC card 15
There is a risk that the multi-function part of the device may be damaged or that data may be entered by pressing the keyboard by mistake. For example, in the case of the IC card 15 with an electric wrapper, there is a risk that the display section 42 or the solar cell section 43 may be damaged, or that the key 41 may be pressed by mistake.

(Means for Solving the Problems) Therefore, in order to solve such problems, the present invention includes a roller for transporting the IC card inserted into the main body to a predetermined position, and a roller for transporting the IC card inserted into the main body to a predetermined position. The roller is provided within the main body so as to bring the roller into frictional contact with the edge of the IC card.

(Function) In this invention, the IC card inserted into the main body is
The contact member is transferred to a predetermined position by a row member that makes frictional contact with this end, and contacts the contact terminal of the IC card that has been transferred to the predetermined position.

Therefore, the keyboard portion or display portion of the IC card is not pressed by the roller.

When the multi-function IC card 15 is inserted between the opening roller 13 and the idle roller 14, the IC card 15 is transferred by the rotation of the rows 513 and 14. A motor 16 is disposed inside the main body 11, and a drive gear 18 is fixed to an output shaft 17 of the motor 16. This drive gear 18 meshes with a driven gear 20 fixed to a drive shaft 19, and the drive shaft 29 is rotatably supported by the frame 11a of the main body 11 via a bearing 21. Pulleys 22 are fixed to both ends of the drive shaft 19, and a belt 23 is hooked and rotated around the pulleys 22.
The hook has also been turned to 4th. Note that a light emitting diode 25 is provided on the side surface where the insertion slot 12 is provided to indicate that an IC card is inserted into the device.

Furthermore, as shown in FIG. 4, a slide guide 26 is disposed within the main body 11 and is movable in the direction of insertion and ejection of the IC card 15 (in the left-right direction in FIG. 4). There is an IC on the distal end side in the insertion direction and at the top.
A contact portion 27 is formed against which the leading end of the card 15 comes into contact, and a tension spring 28 is stretched between the lower portion of the contact portion 27 and the main body 11, and the slide guide 26 is constantly biased in the ejection direction. A housing opening 29 is formed on the insertion opening side of the slide guide 26, and a contact member 3° connected to a computer (not shown) is housed in the housing opening 29 so as to be movable up and down. A contact pin 31 is provided on the upper surface of the contact member 30, and a guide shaft 32 is attached to the lower surface thereof.

Further, a guide bin 35 is installed on the rear end side of the plate cam 33 as shown in FIG. 5, and the guide bin 35 is fitted with the frame 11b of the main body 11, so that the plate cam 33 can move up and down. .

On the other hand, a substantially rod-shaped locking member 36 extending in the ejection direction is swingably attached to the middle of the slide guide 26 via a pivot pin 37 . The retaining member 36 has a claw portion 36a at its tip for positioning the IC card and preventing the inserted IC card from being removed by malicious operation.
have.

Further, the locking member 36 is provided with a locking mechanism (not shown) for maintaining the protruding state when the claw portion 36a protrudes from the surface of the slide guide 26.

A first detector 38 for detecting the insertion of an IC card is disposed inside the main body 11 near the insertion slot 12, and this first detector 38 detects the insertion of the IC card 1 into the main body 11.
This is for detecting the rear end position of No. 5. Also, main body 1
The IC card 15 is inserted into the insertion slot 12 inside the protrusion in the insertion direction of 1.
When this IC card 15 is inserted and transported from
A second detection pin 39 is provided to detect the position of the tip in the insertion direction.

Next, the effect will be explained. FIG. 8 shows a timing chart of this IC card reading/writing device, and the explanation will be made with reference to this timing chart.

As shown in FIG. 4, the operator inserts the IC card 15 into the insertion slot 1.
2, the tip of the IC card 15 is inserted into the first detector 3.
8 detects and transmits this detection signal to a controller (not shown).
The DRV1 circuit outputs a signal to the motor 16, and the motor 16 rotates normally. By the forward rotation of the motor 16, the row 513 is rotationally driven via the belt 23, and the idle roller 14 is driven by the frictional transmission of the roller 13.
It also rotates and prepares to pull in cards. When the IC card 15 is further inserted, both ends of the IC card 15 away from the multi-function part, such as the calculator part having the display part 42, the solar battery part 43, and the keys 44, are held by the roller 13 and the idle roller 14, and come into frictional contact with these parts. , drawn inside.

As shown in FIG. 5, the IC card 15 that has been pulled in comes into contact with the contact portion 27 of the slide guide 26, and the slide guide 26 is moved in the insertion direction against the biasing force of the tension spring 28.

Since the contact outer member 30 is also transferred at the same time as the slide guide 26 is transferred, the back inclined surface 33 of the plate cam 33
The guide @32 located on the b side is the compression spring 3
The plate cam 33 is pushed up against the urging force of 4.
, and move to the front inclined surface 33a side. At this time, the claw portion 36a of the locking member 36 protrudes from the upper surface of the slide guide 26 and locks the rear end of the IC card, and the locking member 36 is fixedly held by the locking mechanism.

The tip of the IC card 15 that is transferred to the back of the main body 11 is
When detected by the detector 39, the detection signal of the second detector 39 is output to the DRV1 circuit, which outputs a signal to the motor 16, and the normal rotation of the motor 16 is stopped.

Next, after a delay of 11 seconds, motor 1 is activated by the output signal of the OR' V 2 circuit of the controller, as shown in Figure 6.
6 is reversed, [1-ra 13 is also driven in reverse, the IC card 15 and slide guide 26 are transferred in the ejection direction,
Contact member 30 also moves in the same direction.

When the contact member 30 moves, the guide shaft 32 located on the front inclined surface 33a side moves up the front inclined surface 33a and is located on the horizontal surface 33c. When the contact member 30 rides on the plate cam 33, the contact pin 31 of the contact member 30 comes into contact with a contact terminal (not shown) of the IC card 15. When the rear end of the IC card 15 is detected by the first detector 38, the first detector 338 outputs a detection signal to the DRV2 circuit, and the output signal of the DRV2 circuit stops the motor 16 from reversing, and the IC card 15 The contact terminal and the contact bin 31 are moved (transferred) to a predetermined position.
and are set in this device by accurately contacting each other without any displacement. When the IC card 15 is set, communication is made with the IC card 15 via the contact bin 31 to read and write information.

As shown in FIG. 7, when the communication with the IC card 15 is completed, a signal for ejecting the IC card 15 is output from the host device (not shown) to the DRV2 circuit, and a signal is sent from the DRV2 circuit to the motor 16 for t2 seconds. The motor 16 is further rotated in the reverse direction, the roller 13 is driven in the reverse direction, and the IC card 1 is
5 is transferred in the discharge direction. At this time, the slide guide 26 is also moved in the ejection direction via the claw portion 36a, but the contact member 30 is also moved in the ejection direction due to the movement of the slide guide 26, and the guide shaft 32 is moved to the horizontal portion 3.
3c, the contact member 30 falls downward.

When the contact member 30 is lowered, the contact pin 31 is separated from the contact terminal of the IC card 15, and the locking mechanism of the claw portion 36a is released and lowered from the upper surface of the slide guide 26. Since a signal is output from the DRV2 circuit to the motor 16 for 2 seconds, the roller 13 is also driven in reverse for 12 seconds.

Therefore, the IC card 15 is at a certain distance in the ejection direction (
J is transferred, a certain portion comes out from the roller 13, and is held between the roller 13 and the idle roller 14. The operator pulls out the IC card 15 from which only a certain portion is protruding from the roller 13 and idle roller 14.

In this way, both ends of the multi-function IC card 15 away from the multi-P3 function section are held between the row 513 and the idle roller 14. Since the multifunctional part is transferred to the predetermined device in frictional contact, the multifunctional part is not pressed by the rollers 13, 14.

In this embodiment, the IC card 15 is transported by a pair of rollers 13 and 14, but it may also be transported by a single roller 45 as shown in FIG. In this case, a plate-shaped spring member 46 is biased and brought into contact with the roller 45.

[Effects of the Invention] As explained above, according to the present invention, the roller is disposed within the main body so as to be in frictional contact with the edge of the IC card, so that the multifunctional part of the IC card is pressed by the roller. That's not the case. Therefore, there is no possibility that the multi-function section of the IC card will be damaged or that the multi-function section will be input.
