Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a manual insertion type IC card reader.

[0002]

2. Description of the Related Art A manual insertion type IC card reader is a method of manually inserting an IC card. The IC card reader sends and receives information signals to and from an IC card in which a memory and a CPU are embedded via a plurality of contact terminals. When inserting and ejecting the card, if the contact between the contact terminal and the card is not broken, there is a fear that the contact terminal may be damaged or the card may be damaged. In the technology disclosed in Japanese Patent Publication No. Sho 63-25392, when the IC card is taken in and out, the vertical movable plate supporting the contact terminal is moved up and down in a direction orthogonal to the card surface, so that the contact terminal and the card are separated from each other. It is designed to break the contact so as to avoid excessive contact between the contact terminal and the card.

[0003]

DISCLOSURE OF THE INVENTION The technique disclosed in the above-mentioned publication is designed to allow the contact terminal to escape from the card passage.
Although it achieves the initial purpose, the problem remains that the entire device becomes thick. Further, it is necessary to prevent the IC card inserted in the recording / reproducing position from being inadvertently ejected until the recording / reproducing operation is completed. If the card with the contact terminals in contact is ejected, the card surface may be damaged or the contact terminals may be damaged.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide a manually insertable card reader in which the entire apparatus is made thin and the card cannot be ejected when the contact terminals are in contact with the card.

[0005]

SUMMARY OF THE INVENTION A manually insertable card reader according to the present invention is urged to advance in the card ejection direction, and rotates with a carrier that moves in conjunction with card insertion and a back side in the card insertion direction. A lock plate that is rotatable as a fulcrum and has a card ejection prevention piece on the front side to move the contact terminal forward and backward with respect to the card storage section; and a lock plate that is provided movably in the card insertion direction and advances into the terminal of the lock plate. It has a stopper for maintaining and releasing the state, and locking means for detecting the insertion of the card at a fixed position and operating to lock the stopper.

[0006]

When the IC card is inserted, the carrier moves while being urged in the card ejecting direction, and when the card is inserted to a predetermined position, the lock plate rotates to the terminal advance state and the contact terminal is inserted into the card. And the card ejection preventing piece of the plate advances into the card storage portion to prevent ejection of the card. The terminal advance state of the lock plate is maintained by the stopper, and the stopper is locked by the locking means.

[0007]

The present invention will be described in detail below with reference to the illustrated embodiments.

(See FIG. 1). Therefore, when the IC card 35 is inserted into the card storage portion 16 from the card insertion slot 2, the IC card 35 hits the card engaging surfaces 5a, 5a, and when the IC card 35 is still pushed in, the carrier 5
Is pushed toward the back (to the left in the figure).

The spring hook 5e of the carrier 5 and the frame 1
A spring 6 is stretched between the spring hook portion 1e and the spring hook portion 1e. The spring force of the spring 6 causes the carrier 5 to move to the IC card 35.
Is urged to move in the direction of ejecting from the card insertion slot 2.

A spring 7 is hooked between the spring hooking portion 5f of the carrier and the spring hooking portion 9f of the stopper 9, and the elastic force of the spring 7 causes the carrier 5 and the stopper 9 to be attracted to each other. Energized, the protrusion 5h of the carrier 5
By contacting the stepped portion 9m of the stopper 9 with each other, the relative movement of the carrier 5 and the stopper 9 due to the biasing force is restricted.

The stopper 9 is provided along one side of the frame 1, and a bent portion 9g formed at the rear end of the stopper 9 fits into the guide groove 1f of the frame 1, and
The stopper 9 is provided so as to be movable in the insertion direction of the IC card 35 by fitting the guide groove 9h formed in the stopper 9 into the guide protrusion 1g formed in the frame 1.

The contact terminals 33 and 34 are provided with signal terminal portions 33a and 34a, respectively, and these terminal portions 33a and 34a are provided on the printed circuit board 2 respectively.
The contact terminals 33 and 34 are finally integrated with the printed board 21 by being soldered to the predetermined wiring pattern portion 1.

The tip portion including the contact portions 33b and 34b of the holder 14 and the contact terminals 33 and 34 is a window hole 8c of the lock plate 8.
The contact portions 33b and 34b of the contact terminals 33 and 34 penetrate the frame 1. Each contact terminal 33 and each contact terminal 34 have the habit of allowing the contact portions 33b and 34b to move into the card storage portion 16 due to the elastic force of the contact terminals 33 and 34. In a normal state such as 7, the support portion A of the lock plate 8,
B is placed on the support piece 5b of the carrier 5 and the support piece 9a of the stopper 9, respectively, so that the lock plate 8 is moved to the leaf spring 30.

It is retracted above 16. In the ascending position of the contact portions 33b and 34b, the contact terminals 33 and 34 are
33d, 3 protruding downward at a position near the base end of the
By contacting the regulating portion 14b of the holder 14 with 4d, the position regulation of the contact terminals 33, 34 and the prevention of falling down are achieved.

In FIG. 7, a leaf spring 29 is fixed to the lower surface of the holder 14 on the card insertion hole 2 side through a spacer. A part of the free end side of the leaf spring 29 advances into the card storage portion 16, and when the IC card 35 is inserted into the card storage portion, the leaf spring 29 comes into contact with the contact point 35a of the IC card 35 and the static electricity of the IC card 35. Is designed to be removed.

FIG. 1. In FIG. 4, the lock plate 8 has an engaging portion 8a formed by obliquely bending a part of the protrusion on the side where the stopper 9 is disposed. On the other hand, the stopper 9 has a protrusion 9e formed on the lower side of the spring hook 9f. As shown in FIGS. 2 and 5, the protrusion 9e is such that the lock plate 8 rotates in the biasing direction of the plate spring 30 and the engaging portion 9c of the stopper 9 bends the locking lever 15. The engaging portion 8a in the state of being engaged with the curved portion 15a
Is pressed from above to securely hold the above-mentioned rotational position of the lock plate 8.

In FIG. 1, a leaf spring 31 is fixed to the frame 1 on the side where the stopper 9 is attached. Leaf spring 3
The free end of No. 1 has advanced into the card storage unit 16, and one side edge of the IC card 35 inserted into the card storage unit 16 is pushed to make the other side edge of the IC card 35 the reference of the card storage unit 16. It is designed to be pressed against the surface.

In FIG. 1, a display lamp 32 is attached to the inside of the side of the eject button 23 so that the operating state of the card reader is lit up so that it can be seen from the outside. It has become.

Next, the operation of the above embodiment will be described. 1, 4, and 7, the support portions A and B of the lock plate 8 are the support piece 5b of the carrier 5 and the support piece 9a of the stopper 9, respectively.
The lock plate 8 is supported by and rotates against the elastic force of the leaf spring 30, and the pair of card ejection preventing pieces 1 of the lock plate 8 are rotated.
1, 11 and contact portions 33b, 34 of the contact terminals 33, 34
It shows a state in which b is retracted above the card storage portion 16. At this time, the stopper 9 moves to the front side (right side in the drawing), and the bent portion 15a of the locking lever 15 is engaged with the engaging portion 9b.

When the IC card 35 is inserted from the card insertion slot 2 into the card storage portion 16 in the card insertion direction b into the card reader in the normal state, the leading edge of the IC card 35 is removed. It hits the card engaging surfaces 5a, 5a of the carrier 5. When the IC card 35 is pushed in, the carrier 5 is moved inward while storing the springs 6 and 7. The stopper 9 is urged in the direction of moving inward by the stored force of the spring 7, but the stopper 9 cannot move because the bent portion 15a of the locking lever 15 is engaged with the engaging portion 9b.

Due to the movement of the carrier 5 accompanying the insertion of the IC card 35, the supporting piece 5b of the carrier eventually escapes from the supporting portion A of the lock plate 8. However, since the support portion B of the lock plate 8 is cantilevered on the spot by the support piece 9a of the stopper 9, the lock plate 8 cannot rotate in the biasing direction of the leaf spring 30. When the carrier 5 moves to the deepest part with the insertion of the IC card 35, the detected part 17 enters the optical path of the photo sensor 18, and the solenoid 19 is excited by the detection signal of the sensor 18. Energization of the solenoid 19 causes the locking lever 15 to rotate counterclockwise in FIG. 1 via the plunger 20 and the pin 27, so that the bent portion 15a of the locking lever 15 and the engaging portion 9b of the stopper 9 are engaged with each other. When the stopper 9 is disengaged, the stopper 9 moves slightly backward by the urging force of the spring 7 and the movement of the stopper 9 is once stopped by the engagement between the engaging portion 9k and the bent portion 15a of the locking lever 15. When 19 is demagnetized and the locking lever 15 returns, it further moves a little further inward and the movement is blocked by the engagement between the engaging portion 9c and the bent portion 15a of the locking lever 15.

By the movement of the stopper 9, as shown in FIGS.
And as shown in FIG. 8, the support piece 9a escapes from the support portion B of the lock plate 8 and the support of the lock plate 8 is released, so that the lock plate 8 is centered on the rotation fulcrums 10, 10. As a result, the leaf spring 30 rotates in the urging direction. At this time, the IC card 35 is the card ejection blocking piece 1 of the lock plate 8.
The card ejection preventing pieces 11 and 11 of the lock plate 8 which are pushed further inward than the positions of 1 and 11 and which are rotated.
Enters the hole 1i of the frame 1 and the hole 3b of the plate 3 to block the discharge passage of the IC card 35.

The guide plate 12 escapes downward from the contact terminals 33 and 34 by the above rotation of the lock plate 8, and the contact terminal 3
3, 34 have their free ends moved downward by their own elastic force, so that the contact portions 33b of the four pairs of contact terminals 33 and the contact portions 34b of the four pairs of contact terminals 34 are respectively in the IC card 3.
5 is pressed against the corresponding card contact 35a. When the pushing force of the IC card 35 is released, the carrier 5 has the springs 6, 7
Although the IC card 35 tries to move in the card ejection direction a due to the stored force of the IC card 35, the front end face of the IC card 35 comes into contact with the card ejection blocking pieces 11, 11 of the lock plate 8 so that the IC card 35 and the carrier 5 is prevented from returning, and the IC card 35 is positioned at the recording / reproducing position.

An overstroke L is provided so that the IC card 35 returns to a certain extent after the IC card 35 is pushed to the deepest portion and reaches the recording / reproducing position shown in FIG. By doing so, the contact portions 33b of the contact terminals 33 and 34,
It is possible to obtain the cleaning effect of the contact portion between the contact portions 33b and 34b of the contact terminals 33 and 34 and the card contact 35a by relatively moving the contact portion 34b while pressing the contact portion 34b.

In this way, information signals are sent to and received from the IC card 35 in a state where the corresponding contact portions 33b and 34b of the contact terminals 33 and 34 are pressed against the card contacts 35a.
The contact terminals 33 and 34 are individually and independently pressed against the card contact 35a by their own elasticity. Even if the IC card 35 is warped or bent, the contact terminals 33 and 34 are connected to the corresponding card contacts 35a of the IC card 35.
Can be contacted well. Also, each contact terminal 3
Since 3 and 34 have two terminal plates as a pair and each terminal plate contacts the corresponding card contact 35a, the contact reliability between the card contact 35a and the contact terminals 33 and 34 can be improved.

In the re-recording ecological position shown in FIGS. 2 and 5, the protrusion 9e of the stopper 9 is slightly moved by the slight movement of the stopper 9.
The engaging portion 8a of is locked from above to prevent the lock plate 8 from being opened accidentally during recording and reproduction.

The IC card 35 is ejected by operating the eject button 23. The detected portion 23a integrated with the eject button 23 blocks the optical path of the photo sensor 24, and the sensor 24 performs a detection operation. The solenoid 19 is excited again by the detection signal of the sensor 24, and the plunger 2
0, the locking lever 15 is rotated via the pin 27 to disengage the bent portion 15a from the engaging portion 9c of the stopper 9, and the stopper 9 is moved toward the inner side by the stored force of the spring 7. Moving. Due to the movement of the stopper 9, the inclined surface 9n of the cut-and-raised portion 9d pushes up the support portion B of the lock plate 8, and the lock plate 8 is rotated upward against the leaf spring 30.
The card ejection blocking pieces 11 and 11 escape upward from the holes 3b and 1j of the plate 3 and the frame 1 to open the ejection passage of the IC card 35. When the lock plate 8 is further rotated, the support portion A of the lock plate 8 is moved to the support piece 5 of the carrier 5.
The carrier 5 tries to return to the original position in the card ejection direction a by the accumulating force of the spring 6 while escaping above b.

3 and 6 show the state immediately before the carrier 5 is about to return. By the above rotation of the lock plate 8, the contact pieces 33, 34 are contacted by the guide piece 12
Is lifted against its own elasticity, and the contact portion 33
b and 34b are separated from the card contact 35a of the IC card 35.

As the carrier 5 returns, the IC card 35 is ejected by the card engaging surfaces 5a, 5a of the carrier 5. In addition, due to the returning operation of the carrier 5, its protruding portion 5h
Pushes the step 9m of the stopper 9 to return the stopper 9 to the original state as shown in FIG. At the final stage of returning the stopper 9, the bent portion 15a of the locking lever 15 rides over the slope of the engaging portion 9b of the stopper 9, and the bent portion 15a engages with the engaging portion 9b.

If the IC card 35 cannot be ejected even if the eject button 23 is pressed due to a power failure during recording / reproduction or the solenoid 19 is broken, a pin or the like is inserted from the small hole 1i of the frame 1 to operate the manual lever 22. Bend 3
By pushing 3b, as described above, the IC card can be ejected by performing the same operation as when the solenoid 19 is excited.

In the above example, two types of contact terminals 33 and 34 having different lengths are used, and the short contact terminal 33 is arranged so as to be held by the long contact terminal 34. It is possible to reduce the space occupied by the contact terminals while increasing the reliability of the contact by contacting the individual contact terminals. However, such arrangement of the contact terminals is not essential to the present invention, and different arrangements may be adopted, or only one contact terminal may be in contact with one card contact. 7 shows another example of the contact terminal applicable to the present invention. In the example shown in FIG. 10, a box-shaped holder 45 is fixed to the lower surface of the printed circuit board 21 fixed to the lower surface of the cover 4, and an elastic conductive plate is punched into the holder 45 in a bilaterally symmetrical angular wave shape. The contact terminal 46 formed by
6a and 46a are projected from the hole 45a of the holder 45. The contact terminal 46 itself has elasticity by being punched into a square wave shape, and this elasticity causes the contact portions 46a, 4
6a comes into pressure contact with the contact 35a of the IC card 35. The upper end protruding portion 46 b of the contact terminal 46 is soldered to the printed board 21. Such contact terminals are provided corresponding to the number of contacts 35a of the IC card 35. Also in the case of this embodiment, the contact portions 46a and 46a are individually and independently pressed against the card contact 35a by elastic force. In addition, the same effect as that of the above-described embodiment is obtained.

The example of FIG. 11 is an example in which the contact terminal is made of a wire material instead of a plate material, and the conductive wire material having elasticity is U.
A U-shaped contact terminal 48 is bent into a contact terminal 48, and the two free ends 48a, 48a of the U-shaped contact terminal 48 are used as contact portions for the contact 35a of the card, and the base end 48b of the contact terminal 48 is not shown in the holder. It is designed to be held by. In the case of this embodiment, the same effect as that of the above embodiment can be obtained.

[0045]

As described above, according to the present invention, since the contact terminal is brought into contact with and separated from the card by the rotatable lock plate, the device can be made thin. Further, since the card ejection preventing piece provided on the lock plate prevents the card from being ejected, the device can be made thin and at the same time, the card can be prevented from being ejected inadvertently and damage to the card can be avoided.
