[Function] The rear end of the card is hooked by the claws and sent out.

[0007]

FIG. 3 shows the entire shape of the nail 3. This claw has a general shape having a brim-shaped portion on both sides of a prismatic block, and the upper part of the general block engages with a slit-shaped guide when traveling in the card feeding direction F so as to engage with a predetermined slit corresponding to the slit. An upper surface portion 3a having a width W and in contact with the card surface, a clearance groove 3b formed at the rear end portion of the upper surface portion in the card feeding direction, and rising from the clearance groove 3b and extending from the upper surface portion 3b Also have a convex portion 3c for locking the card, which protrudes upward.

Reference numeral 3d designates a brim-shaped portion which is formed in the middle part of the claw 3 in the vertical direction and protrudes in the horizontal direction. The claw 3 is formed with a hole 3e for penetrating a claw shaft described later in the longitudinal direction.

As described above, the convex portion 3c is used for hooking the card when the card is sent out, and FIG. 4 shows this portion in an enlarged manner. The rear end of the card 2 is caught by the projection 3c, so that only one
The height from a to the upper surface of the projection 3c is 50 to 70% of the thickness of the card 2.

Further, as shown in an enlarged manner in FIG.
Is a sharp angle to the upper surface 3a, that is,
It is formed in a hook shape with an angle θ with respect to the vertical plane. This makes it easier to grasp the rear end of the card. Also,
By providing the escape groove 3b, the influence of paper dust, dust and the like can be avoided.

In FIG. 5, reference numeral 4 denotes a card mounting plate on which the card 2 is mounted, and a slit-shaped guide 4a is formed on the card mounting plate. The guide 4a is engaged with a portion having a width W above the flange 3d of the claw 3, and the claw 3 is guided by the guide 4a to feed the card in the card feeding direction F.
It can run freely.

An outline of the reciprocating means of the claw 3 will be described with reference to FIGS. As shown in these figures, the pawl 3 is pivotally attached to a pawl arm plate 6 via a pawl shaft 5 penetrating a hole 3e (see FIG. 3). The claw arm plate 6 is rotatable with respect to the claw guide plate 7. The claw guide plate 7 has a nut portion 7 a integrally formed therewith screwed to the feed screw shaft 8.

The feed screw shaft 8 is set parallel to the card feeding direction F, and both ends thereof are rotatably attached to the side plates 9 and 10. A pulley 11 is attached to a protruding end of the feed screw shaft 8 on the side plate 9 side. Also, the side plate 9
Has a motor 13 attached thereto, and a pulley 12 is also attached to the shaft of the motor.
A belt 13 is hung between 1 and 12.

On the other hand, guide shafts 15 and 16 are provided between the side plates 9 and 10 in parallel with the feed screw shaft 8. The guide shaft 15 is
The guide bush 21 (see FIG. 2), which pivotally connects the claw guide plate 7 and the claw arm plate 6, slidably penetrates, and the guide shaft 16 slidably penetrates the claw guide plate 7. doing.

Thus, the pawl guide plate 7 is connected to the guide shaft 1.
Since the rotation of the feed screw shaft 8 is stopped by the rotation of the feed screw shaft 8, the claw 3 is moved together with the claw guide plate 7, the claw arm plate 6, and the like.

That is, the claw 3 travels in the card feeding direction F or in the reverse direction according to the forward / reverse rotation of the motor 14. Therefore, the pawl guide plate 7, the feed screw shaft 8, the motor 14, the guide shafts 15, 16 and the like constitute the main members of the pawl reciprocating means.

With this configuration, if the rear end of the lowermost card 2 is hooked on the projection 3c of the claw 3 as shown in FIG. 6, the card 2 can be sent out by the rotation of the feed screw shaft 8. .

In this embodiment, a means is provided for urging the claws 3 toward the card side so that the card can be surely hooked on the projection 3c even if the card is bent. This advance urging means will be described with reference to an exploded perspective view shown in FIG. 2 and a perspective view in an assembled state shown in FIG.

In the figure, a claw shaft 5 to which a claw 3 is attached is shown.
Is pivotally attached to a claw arm plate 6 having a rectangular frame shape and is prevented from falling off by a retaining ring 20.

The claw arm plate 6 and the claw guide plate 7 are attached to each other through one end of a hollow shaft-shaped guide bush 21 mounted on the base end side of the claw arm plate 6 through a hole 7b of the claw guide plate 7. It is configured to be penetrated to the outside and stopped by a stop ring 22.

Here, the hollow portion of the guide bush 21 is slidably fitted on the guide shaft 15. Also, the claw guide plate 7
The groove 23a of the guide bush 23 is fitted and fixed to the U-shaped notch 7c.
, A guide shaft 16 is slidably fitted.

Accordingly, the claw arm plate 6 is rotatable about the guide bush 21 with respect to the claw guide plate 7.
Accordingly, the claw 3 is also swingable. Further, a torsion coil spring 24 is wound around the guide bush 21, one end 24a of the torsion coil spring 24 is inserted into the hole 7d of the claw guide plate 7, and the other end 24b is a frame portion of the claw guide plate 6. It is hung on the upper part of 6a.

With this configuration, the torsion coil spring 24
Thus, the free end side of the claw arm plate 6 is urged upward. Since there is a card above, the direction of this bias matches the direction in which the claw 3 advances to the card 2 side. Therefore, the claw arm plate 6, the guide bush 21, the torsion coil spring 24, and the like constitute main members of the urging means.

Next, the card feeding operation will be described.
As shown by a two-dot chain line in FIG. 6, the home position of the claw 3 is set at a position where the protrusion 3 c is separated from the card on the right side of the rear end of the stacked cards 2. In this state, the card is stored on the card mounting plate 4.

As shown in FIG. 7, two support plates 17, 1 standing upright facing the card width direction are placed on the card placement plate 4.
The card is placed between these support plates, and a weight 19 is placed on the card.

The rear end of the cards 2 stacked on the card placing plate 4 is supported by a support plate (not shown) at the position shown in FIG. As for the front end side of the stacked cards, as shown in FIG. 8, the forward movement is regulated by guides arranged so as to allow the single card to be sent out, and only the lowermost card is sent out. Is sent out by a feed roller through the gap.

In the initial stage of storage, since the weight of the card is sufficient, the lowermost card generally does not bend. In this case, as shown in FIG. 7, the pawl 3 is pushed down by the weight of the card 2 or the weight 19, which is larger than the upward force by the urging means, and the upper surface portion 3a is at the same level as the upper surface of the card mounting plate 4. The protrusion 3c is less than the thickness of the card lower than the upper surface of the card placing plate 4, but protrudes by a sufficient amount for feeding. By driving the motor 14 in this state, the pawl 3 starts moving from the home position in the card feeding direction F, and the lowermost card is hung on the convex portion 3c and sent out.

By the way, as the number of cards decreases, the uppermost curve appears on the lowermost card, and the end of the card escapes from the projection 3c. However, following this escape, collar part 3
With the upper limit of the position where d contacts the card mounting plate 4, the pawl 3 is lifted by the urging means. As a result, the end of the curved card is also hooked on the convex portion 3c, and the card is sent.

When the leading end of the card sent in this way reaches a predetermined feed position such as being succeeded by the next feeding means, the feed screw shaft 8 is rotated in the reverse direction, and the claw 3 moves in the opposite direction to that of the home and moves to the home position. Return to position. In the process of returning to the home position, the convex portion 3c passes over the rear end of the lowermost card, whereby the convex portion 3c is positioned to the right of the end of the card so that the card can be fed.

In this embodiment, the pivot axis of the claw arm plate 6 is parallel to the card feeding direction F. However, the pivot axis can be set in a direction perpendicular to the card feeding direction F.
