Next, the processing operation of a card in the card processing apparatus thus configured will be described. As shown in FIG. 5A, the card take-in path 32 of the card processing apparatus 1
In a state in which the card 80 is not taken in and the card insertion slot 21 of the pushing member 3 is not pushed in the direction of the arrow A by hand, as shown in FIG. The protrusion 59 of 51 is in contact with the protrusion 15 a of the fixed cam 15. Therefore, as shown in FIG. 6A, the bent portion 56 of the card take-in member 51 is elastically deformed upward in the figure, and the second portion of the bent portion 56 is deformed.
Of the card insertion member 2 of the card pushing member 3
2 and the card insertion slot 22 is opened, and the card 8
0 can be inserted into the apparatus. Further, as shown in FIG. 4B, the state where the first engagement portion 57 of the card take-in member 51 and the engagement piece 40 of the moving member 4 are separated from each other by a distance D is maintained.

In this state, as shown in FIG.
8 is inserted from the card insertion slot 22 into the card take-in passage 32, and the card 80 is inserted until the rear end of the card 80 coincides with the surface of the card insertion slot 21 of the pushing member 3 as shown in FIG. Push in. The front end of the card 80 pushed in this way is engaged with the engaging claw 53 of the card ejection member 50, and as shown in FIG.
The moving member 4 held in the stopped state is moved in the direction of arrow A by the card 80 pushed in against the pulling force of the pulling coil spring 52.

Next, as shown in FIG. 10 (a), the card insertion slot 21 of the pushing member 3 is moved by hand by a moving amount C1.
When the moving member 4 is pushed only in the direction of arrow A, the moving member 4 moves in the direction of arrow A by a moving amount D larger than C1 via the moving amount converting means 5 as shown in FIG. in this case,
Since the card 80 is urged by the card ejection member 50 in the direction of arrow B and is pressed by a finger so as not to come out of the card insertion slot 22, the card 80 moves by the same movement amount C1 as the pushing member 3.

Therefore, the movable member 4 which has moved by the moving amount D is movably supported in the direction of arrow AB, and the moving amount C
The card ejection member 50 in which the front end of one card 80 is engaged by the engagement claw 53 moves in the direction of arrow B by the moving amount (D-C1) by the tensile force of the tension coil spring 52. At this time, as shown in FIG.
A play D1 is formed between the convex strip 38 and the engagement groove 54 of the card ejection member 50. Therefore, the tensile force of the tension coil spring 52 in the direction of arrow B acts on the card ejection member 50, and the card 80 is also urged in the direction of arrow B.

When the engaging piece 40 of the moving member 4 moves by the moving amount D in the direction of the arrow A, as shown in FIG. Is engaged with the engagement piece 57. Therefore, the moving member 4
Despite the movement of the card taking member 51, the card engaging member 51 does not move, so the second engaging portion 58 of the card taking member 51 does not move, and the card taking member 51 is kept in a position in contact with the back surface of the case 11. It is positioned. Therefore, the second engagement portion 58 is located at a position slightly shifted in the direction of arrow B in the figure from the rear end of the card 80 moved in the direction of arrow A by the movement amount C1. Further, since the card capturing member 51 has not moved in the direction of arrow A,
The protrusion 59 of the card take-in member 51 is in contact with the protrusion 15a of the fixed cam 15, and is held in a state of being locked by the small protrusion 15c.

When the pushing member 3 is further pushed in the direction of arrow A, the moving member 4 also moves in the direction of arrow A, and the engaging piece 40 of the moving member 4 engages with the first engaging piece 57 of the card taking-in member 51. By matching, the card capturing member 51
Also moves in the direction of arrow A. Therefore, as shown in FIG. 7A, the projection 59 of the card take-in member 51 locked on the small projection 15c of the fixed cam 15 rides on the small projection 15c as shown in FIG. As shown in FIG. 14C, the projection 59 gets over the small projection 15c. As shown in FIG. 4D, the projection 59 comes into contact with the chamfered portion 15b, so that the bent portion 56 of the card take-in member 51 elastically returns in the clockwise direction in the figure, and the second engagement portion 58 becomes Engage with the rear end of the card 80. As described above, when the second engaging portion 58 is engaged or disengaged with the rear end of the card 80, the elastic return of the bent portion 56 itself of the card take-in member 51 is used, so that the number of parts is reduced. Not only is reduced, but also the structure is simplified.

At this time, as described above with reference to FIG. 11C, the card 80 is urged in the direction of arrow B by the pulling force of the pulling coil spring 52 via the card ejection member 50. The card is ejected and held by the card ejection member 50 and the card take-in member 51. Here, as shown in FIG. 6B, by providing a play having a length D between the engagement piece 40 of the moving member 4 and the first engagement portion 57 of the card take-in member 51, The card capturing member 51 does not move until the rear end 80 passes below the second engagement portion of the card capturing member 51.

Therefore, as shown in FIG.
When the second engagement portion 58 engages the rear end of the card 80, the card 80 that has not completely passed through the second engagement portion 58
The rear end of the card 80 is securely held by the second engagement portion 58 because the rearward end of the card 80 is prevented. Moreover, the front end of the card 80 is held by the engaging claw 53 of the card ejection member 50 urged in the direction of arrow B by the tensile force of the extension coil spring 52,
The card 80 is held by the card ejection member 50 and the card take-in member 51, so that the card 80 can be securely held by the card holding means 6.

As shown in FIG. 12, when the card insertion opening 21 of the pushing member 3 is pushed by the pushing amount C in the direction of arrow A, the moving member 4 is moved
The card 80 moves in the direction of arrow A by the amount of movement C2, and the card holding means 6 moves integrally with the moving member 4. At this time, as shown in FIG. 12, the front end of the piston 26 of the pushing member 3 is in contact with the bottom of the cylinder 17 of the base 2. As described above, since the card 80 moves by the moving amount C2 larger than the pushing amount C of the pushing member 3, the card 80 is moved in a state where the rear end of the card 80 is separated from the card insertion slot 22 of the pushing member 3. It is taken into the intake passage 32. Therefore,
The card 80 which is taken into the card taking-in passage 32 and processed by the card processing device 33
Is prevented from being intentionally or erroneously removed from the card insertion slot 22, so that a card failure does not occur.

The moving amount converting means 5 for moving the card 80 more than the pressing amount of the pressing member 3 includes:
As shown in FIG. 5B, the fulcrum 46 of the link lever 45 is provided on the base 2, the important point 47 is provided on the pushing member 3, the power point 48 is provided on the moving member 4, and the link lever 45 is extended. Therefore, the number of components constituting the movement amount conversion means 5 is reduced, the structure is simplified, and the size of the apparatus is reduced.

Next, the locking operation by the locking means 7 will be described with reference to FIGS. As shown in FIG. 5B, in an initial state in which the card 80 is not inserted from the card insertion slot 22 and the pushing member 3 is not pushed in, the tension coil spring 72 makes the shaft 68 rotate around the shaft 68 as a center of rotation. The pressing portion 67 of the pressing lever 65 urged to rotate counterclockwise in the figure presses the upper end of the pressing member 3.

In this initial state, FIG.
Since the distance W between the line segment L connecting the spring retaining portions I and R at both ends of the tension coil spring 72 and the rotation center G of the pressing lever 65 is set small as shown in FIG. The rotational moment M1 for rotating the pressing lever 65 generated at the point R with respect to the tensile force F of the coil spring 72 is small. Therefore, since the rotational moment M1 at the point S by the pressing portion 67 of the pressing lever 65 pressing the upper end of the pressing member 3 is also small, the upper end of the pressing member 3 is pressed by the pressing portion 67, which is a component force of the rotating moment M1. The pressing force for pressing is also small. For this reason, the pushing member 3
When pushing the pushing member 3 in the direction of arrow A, the load acting in the direction opposite to the pushing direction is small, so that no load is applied to the hand pushing the pushing member 3.

From the state shown in FIG. 5B, as described above,
Immediately before the card 80 is inserted from the card insertion slot 22 and the pushing member 3 is pushed in the direction of arrow A by the pushing amount C,
As shown in FIG. 14, the lower end of the pressing portion 67 of the pressing lever 65 engages with the engaging recess 25 of the pushing member 3. At this time, as described above, at the point S engaged with the engaging recess 25 of the pressing portion 67 of the pressing lever 65, a rotational moment larger than the rotational moment M1 is generated, and this rotational moment gradually increases. This rotational moment is generated in the direction opposite to the tension coil spring 27 that urges the pushing member 3 in the card discharging direction, that is, in the direction of arrow B, that is, in the direction of arrow A that is the card insertion direction.

Therefore, the urging force in the card discharging direction by the tension coil spring 27 increases at the pushing end side where the pushing member 3 is pushed, but the urging force by the tension coil spring 27 is generated by the rotational moment M1 of the tension coil spring 72. Is offset. For this reason,
At the pushing end side where the pushing member 3 is pushed in, since no load is applied to the hand, the card 8 due to insufficient pushing is pressed.
The failure of taking 0 is prevented.

Further, at the pushing end of the pushing member 3, as shown in FIG. 15 (b), the points R, G and S are located on a straight line in the vertical direction, and the line segment L is located at the points R and G.
Since it is orthogonal to the line connecting the point S, the moment M2 generated at the point R becomes the same as F and becomes the maximum. The moment M2 also occurs at the point S, and the direction of the moment M2 at the point S is exactly opposite to that of the extension coil spring 27, so that the tension force of the extension coil spring 27 is reduced to the maximum. For this reason, at the end of the press, the hand is given the feeling that the press is completed, which not only gives the user a sense of security, but also prevents the user from stopping the press before the press is completed. Usability is improved.

At the end of the pushing, the pushing lever 6
5 is engaged with the notch 74 of the locking lever 73, and the locking lever 73 is always rotated in the counterclockwise direction about the shaft 75 by the rod 78 of the solenoid 77. Since it is biased, the rotation of the pressing lever 65 due to the pulling force of the pulling coil spring 72 is restricted. Therefore, the pushing member 3 is locked by the locking means 7, so that the card 80 is also kept in a state where the movement of the card 80 is stopped.
Are processed. While processing this data, FIG.
As shown in FIG. 7, even if the second card 80A is erroneously inserted from the card insertion slot 22, the second engagement portion 58 of the card take-in member 51 functions as a shutter.
The taking-in of the second card 80A into the card taking-in passage 32 is regulated. Therefore, it is possible to prevent a trouble in the card processing operation of the first card 80 during the card processing.

When the data processing is completed, the solenoid 7
When the rod 78 is retracted, the locking lever 73 rotates clockwise about the shaft 75, so that the locking portion 65 of the pressing lever 65 engages with the notch 74. It is released. Here, the tensile force of the tension coil spring 27 that urges the pushing member 3 in the discharging direction is set to be larger than the tensile force of the tension coil spring 72 that urges the pushing member 3 in the taking-in direction. The pushing member 3 moves in the discharging direction, that is, the direction of arrow B in the figure.

At this time, as described above, the piston 26 of the pushing member 3 is attached to the bottom of the cylinder 17 of the base 2.
Abuts, no air is interposed between the bottom of the cylinder 17 and the piston 26. Moreover,
The cylinder portion 17 is hermetically closed by the piston portion 26, and has only a slight air vent hole 18. Therefore, when the pushing member 3 starts moving in the direction of the arrow B by the tensile force of the tension coil spring 27, the pressing member 3 is moved between the cylinder portion 17 and the piston portion 26.
A negative pressure acting in the direction opposite to the tensile force of the tension coil spring 27 is generated.

For this reason, the pushing member 3 is gradually moved by the large tensile force accumulated in the extension coil spring 27 without suddenly moving in the direction of arrow A, so that the pushing member 3 is discharged from the card insertion slot 22. Card 8
0 can be prevented from accidentally falling from the card insertion slot 22. As described above, the cylinder 17 is provided on the base 2 to temporarily reduce the discharge speed at the start of discharging the pushing member 3, and the cylinder 17 is sealed by the piston 26 provided on the pushing member 3. Just do
The number of parts is reduced, the structure is simplified, and the device is downsized.

As shown in FIG. 16, when the pushing member 3 moves in the direction of arrow B, the protrusion 59 of the card taking member 51 approaches the fixed cam 15, and when the pushing member 3 further moves, the pushing member 3 moves as shown in FIG. As shown, the protrusion 59 is
5, the protrusion 59 slides on the chamfered portion 15b rightward in the figure. As shown in FIG. 9C, the projection 59 is engaged with the small projection 15c of the fixed cam 15, so that the bent portion 56 of the card take-in member 51 is elastically deformed upward in the figure, and the rear end of the card 80. And the second engaging portion 58 of the card take-in member 51 is released.

Here, as shown in FIG. 16A, the front end of the card 80 is held by the engaging claw 53 of the card ejection member 50 by the tensile force of the extension coil spring 52, so that the rear end is The card 80 having been disengaged from the second engaging portion 58 is repelled in the direction of arrow B by the tensile force of the tension coil spring 52. Therefore, the rear end of the card 80 protrudes from the card insertion slot 22 of the pushing member 3 and is exposed to the outside, so that the user can grip the exposed rear end of the card 80 with his / her finger. It becomes easier and usability is improved.

As shown in FIG. 6B, the projection 59 rides on the small projection 15c, and as shown in FIG.
As shown in FIG. 5 (a), the pushing member 3 moves over the small projection 15c and engages with the small projection 15c.
Is inserted into the case 11 of the base 2, and the pushing member 3 returns to the initial position.

In the embodiment of the present invention, the card processing device can use a non-contact type IC card. However, the present invention can be applied to a card processing device which can use a contact type IC card.
