Further, in the above-mentioned clutch, a through hole is formed in the feeding roller (delivery roller) located on the clutch side, and a pin fixed to the rotating plate is configured to penetrate the through hole and mesh with the clutch. (Page 3, upper left of the same publication).

(Problem to be Solved by the Invention) Such a card feeding device tries to solve the problem that two cards are fed in an overlapping state when a thin card is fed from the lower end of the card stack by a roller. However, there was a problem in the structure of the clutch drivingly connected to the drive shaft.

That is, since the above-mentioned clutch has a structure in which the pin is passed through the through hole, a high dimensional accuracy is required for both, so the structural unit cost is high, and the timing for passing the pin through the rotationally moving through hole is high. It is not always easy to align the rotation plate with the clutch pin, and when the rotation plate with the clutch pin fixed is pulled toward the clutch, the rotation plate will reach the maximum until it engages with the clutch.
There was a problem that the operation time became long because it had to wait for 360 degrees to rotate.

The technical problem to be solved by the present invention is to solve the above-mentioned problems, and the manufacturing unit price is low, the timing of clutch engagement is easily adjusted, and the use of a clutch having a short operation time allows one operation to be performed.

(Example) The Example of this invention is described based on each drawing.

FIG. 1 is a perspective view showing the entire card sending device according to the present invention, and FIG. 2 is a right side view of the same device. First, as shown in FIG. 1, the side plate 1 and the side plate 2 form a card storage part 101 for storing a card stack, and both side plates are formed.
A support plate 4 that supports the card stack is provided between the first and second parts. The drive shaft 6 is arranged on the lower side of the support plate 4, that is, on the opposite side of the card accommodating portion 101, and both ends thereof are supported by the side plates 1 and 2, respectively. The payout roller 5 is rotatably supported on the drive shaft 6 with respect to the drive shaft 6.

On the other hand, as shown in FIG. 2, a delivery roller 7 is provided in front of the delivery roller 5 in the card delivery direction, a reversing roller 8 for preventing overlap feeding is provided above the delivery roller 7, and is ejected forward of the delivery roller 7 in the card delivery direction. Roller 9
Then, the discharge assisting rollers 10 are arranged above the discharge rollers 9, respectively. Here, the delivery roller 7 is a roller shaft.
It should be installed so as to rotate independently of the rotation of 11. As a result, when the card is forcibly sent out by the driving force generated by the rotation of the roller shaft 11, two or more cards may overlap and bite, which can be prevented. Further, the reverse rotation roller 8 is fixedly provided on the roller shaft 12 and rotated in the direction opposite to the card feeding direction to prevent the card from overlapping and being caught in the card in cooperation with the feeding roller 7. Further, the discharge roller 9 is fixed to the roller shaft 13 and the discharge auxiliary roller 10 is fixed to the roller shaft 14, respectively.

Then, both ends of each of the roller shafts 11 to 14 are rotatably supported by the side plate 1 and the side plate 2, respectively, and the side plate side tips are protruded to the outside of the side plate 1. A pulley 20 (see FIG. 4) is fixedly provided at the tip of the roller shaft 12, and a pulley 21 is fixedly provided at the tip of the roller shaft 13.

Next, in FIGS. 1 and 2, reference numeral 15 indicates a driving DC motor for driving the above-mentioned feeding roller 5 and the like via the belt 18 and the belt 23, and a motor shaft 16 of the motor 15 A pulley 17 for driving a belt 18 is fixedly provided in the. The belt 1 is connected to the roller shaft 11 via the pulley 19, to the roller shaft 12 via the pulley 20, and to the pulley shaft 12.
The driving force of the motor 15 is transmitted to the roller shaft 13 via 21. Further, as shown in FIG. 4, a pulley 22 fixedly provided on the roller shaft 11 drives a belt 23, and the belt 23 transmits the driving force of the drive shaft 6 via the pulley 24.

Now, turning to FIG. 6, the manner in which the clutch roller engages with the clutch pin will be described. First, the feeding roller 5
As already described, the above is rotatably supported on the drive shaft 6 via the clutch roller 26 integral therewith. Then, on the side surface of the clutch roller 26, there are three clutch pins 27 ..
Are provided so as to elastically project from the respective support holes by a spring (not shown) provided inside the clutch roller 26.

On the other hand, as shown in FIGS. 3 and 4, the clutch pin 27 ..
A drive cam 30 configured to rotate integrally with the drive shaft 6 and to be slidable in the axial direction of the drive shaft 6 is provided at a position opposed to. The drive cam 30 is engaged with any one of the clutch pins 27 .. The two pawls 28 and 29 for drivingly connecting the drive shaft 6 and the feeding roller 5 are separated from each other in the circumferential direction of the drive cam 30. Set up. Further, a slide ring 31 that rotates integrally with the drive cam 30 is mounted on the drive shaft 6 on the side opposite to the clutch roller 26. An outer peripheral recess 32a for receiving one end of a clutch lever pin 32 (FIG. 3) described below is formed over the entire outer periphery of the slide ring 31. The outer peripheral recess 32a is formed so that one end of the received clutch lever pin 32 does not hinder the rotation of the slide ring 31. Then, the other end of the clutch lever pin 32 is attached to the clutch lever 33 (Fig. 4). Further, one end of the clutch lever 33 is attached to a substrate (not shown) via a pivot pin 36, and the other end thereof is attached to a movable piece 35 of the solenoid 34.
When moving in the direction of the arrow shown, the clutch lever 33
Is rotatable about the pivot pin 36.

When the solenoid 34 is energized, the solenoid 34 pulls the movable piece 35 in the upward direction of the arrow shown in FIG. 4, and rotates the clutch lever 33 around the pivot pin 36 in the arrow direction. As a result, as shown in FIG. 3, the clutch lever pin 32 moves through the slide ring 31, the drive cam 30 moves to the right in the figure, and the clutch is engaged, and the drive shaft 6 moves out through the clutch roller 26. It is drivingly connected to the roller 5.

This will be explained in detail as follows. That is,
When the drive motor 15 is rotating, the drive cam 30
Of the three clutch pins 27 .., one or two of the three clutch pins 27 .. will be pushed by the drive cam without countering the force in its support bore spring (not shown). Therefore, these clutch pins 27 do not participate in the engagement of the claws 28 of the drive cam 30 as described below. on the other hand,
Since the one clutch pin 27 that has not been pushed in is still protruding from the surface of the clutch roller 26, when the drive cam 30 rotates, the one clutch pin 27 engages with the claw 28 of the drive cam 30 in due course. In this way, when three clutch pins are provided at equal intervals, the drive cam 30 has a maximum of 120 degrees (when there are two clutch pins, the maximum is 180 degrees, and when there are four or more, the angle corresponding to the number is ) By rotating, the claw 28 and the clutch pin 27 can be engaged. With such a configuration, the operation time can be shortened as compared with the case where a maximum rotation angle of 360 degrees is required when only a single clutch pin is provided.

As described above, the driving force of the drive motor 15 is transmitted to the feeding roller 5 drivingly connected to the drive shaft 6, and as a result, the feeding roller 5 moves the card at the lower end of the card stack 3 in the card housing portion 101. Let out. On the other hand, solenoid
When the power supply to 34 is cut off, the drive cam
30 moves in the clutch disengagement direction, that is, to the left in FIG. 3, and the claws of the drive cam 30 and the clutch pin 27 disengage. As a result, the drive connection between the feeding roller 5 and the drive shaft 6 is released, and the card feeding action of the feeding roller 5 is stopped. Next, the form of the feeding roller will be described with reference to FIG. Protrusions 37 made of urethane rubber are provided on the outer circumference of the pay-out roller 5 over almost half of the circumference. As shown in FIG. 1, when the feeding roller 5 rotates, the projection 37 projects upward from the support plate 4 through a window 38 provided in the support plate 4 and engages the card at the lowermost end of the card stack 3. Then, it is configured to send out one card. Reference numeral 39 shown in the figure is a weight for pushing down the card laminated body 3 toward the support plate 4.

Further, as shown in FIG. 2, a photocell 41 for confirming the sending of the card is provided at the card sending / receiving port 40 with a sending part 41a and a receiving part 41b.
And are arranged facing each other in the thickness direction. Further, at a position adjacent to the photocell 41, a shutter 42 is pivotally attached to the side plate 1 and the side plate 2 so as to be swung by the sending card. The shutter 42 pressed by the sending card rotates clockwise in the figure, and its free end eventually enters between the transmitting section 41a and the receiving section 41b, whereby the sending of the card can be confirmed. . In this way, if the sending card itself is not directly detected, it is possible to confirm the sending even if the light passes through such as a transparent card. Furthermore, since the shutter 42 is configured to close the card outlet 40, it is possible to prevent the card from being messed up and removed.

Reference numeral 43 shown in FIG. 5 is a micro switch for detecting empty of the card, reference numeral 44 is a switch arm of the micro switch, and reference numeral 45 is a stopper plate for promoting alignment of the card stack. Are shown respectively.

(Effects of the Invention) According to the card sending device of the present invention, it is easy to adjust the timing of clutch engagement at a low manufacturing unit price.
1 in 1 motion by using a clutch with short operating time
It is possible to reliably and quickly send out a single card.
