Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a feed direction conversion device using a parallelogram link mechanism.

In recent years, there has been a remarkable trend toward a cashless society where people can shop using a credit card without carrying cash, and for this reason, terminal devices such as magnetic card devices that are suitable for various uses have been developed.

In such a terminal device, in order to keep a record of the usage of the credit card used, two rolls of paper on which the amount used, etc. are printed in the print section are placed in the embossed section of the credit card (the imprint section). Press it with a roller and emboss it on the paper (e.g. credit card holder number).

(account number, etc.), and after imprinting is complete (
The upper roll of paper is wound up as a take-up roll (a journal), and the lower roll of paper is cut with a roll cutter to form a receipt and returned to the user along with the credit card. method is commonly used.

In this case, conventionally, the receipt and credit card were first moved sideways, then transferred back to the user, and returned to the user, which increased the width of the device and was disadvantageous in terms of space. .

In such a case, the problem can be solved by moving the receipt and credit card one step downwards, then moving them one step toward the front, and returning them one step below the card insertion slot.

The present invention is aimed at realizing this, and provides a feeding direction changing device that can transport media such as receipts, credit cards, etc. that have been transferred forward one direction, move them downward, and then discharge them to the front. The purpose is to

The present invention will now be described in detail with reference to the drawings.

1 and 2, 1 is the drive shaft, 180
It can be rotated in degrees.

2. 2' and 3 are cams of the same shape, and are each fixed at a predetermined position on the drive shaft 1 in the same phase.

4, 4' and 5°5' are identically shaped links fixed to both ends of rotatable shafts 6 and 7, respectively.

8. 8' is a roller, and the cam 2 of arms 4 and 4' respectively.
, 2' and the corresponding positions are rotatably supported.

It is.

Reference numerals 9 and 9' designate connecting plates, which are connected to the link 4.5 and the tips of links 4/ and 5/, respectively, via shafts 10° and 11.

The link 4.5 and the connecting plate 9, and the link 4/51 and the connecting plate 9' form a pair of parallelogram link mechanisms 30 with the shafts 6 and 7 as fulcrums, respectively.

Reference numerals 12 and 12' designate holding members such as feed rollers, each of which supports a shaft 13.1 rotatably around the connecting plate 9°9'.
3'+ is fixed.

14 and 14' are gears fixed at one end of the shafts 13 and 13', 15 is a transfer medium storage box connected to both ends of the connecting plate 9 and 9', and 16 is a rotatable shaft 6I. The supporting metal fitting 17 is the position corresponding to the cam 3 of the supporting metal fitting 16! The supported roller 18 is a leaf spring fixed to a support fitting 161.

The tip of the leaf spring 18 engages with an axle 19 connecting the link 4.4'.

20 is a cam fixed to the drive shaft 1], 21 is a fixed shaft 22
(The energizing fitting 23 is rotatable to a position corresponding to the cam 20 of the energizing fitting 21.) The supported roller 24 is a supporting device that rotates the energizing fitting 21 in the direction of arrow A. The springs 25, 25' are biased in the clockwise direction l in Figure 1.
The rotating drive member is, for example, a drive gear.

The configuration of the present invention is as described above, but the following (effect 1)
Let me explain in detail.

When the cams 2.2' and 3 are at the position indicated by the solid line in Figure 1,
The upper parts of these cams are the respective rollers 8, 8'.

17, and the parallelogram link mechanism 30 is at the suction position 1 shown by the solid line, and the gear 14 and the drive gear 25 are in mesh with each other.

Therefore, the feed roller 12 is connected to the gear 14 by the drive gear 251.
, through the shaft 13 in the counterclockwise direction in FIG. Subsequently, it is transferred to the front and held in the storage box 15.

. Further, since the links 4 and 4' are pushed up by the action of the leaf spring 18, the gear 25 and the gear 14 are reliably engaged.

When the drive shaft 1 is rotated 180 degrees, the cam 2.2'
, 3 also rotate once with the drive shaft 1, and each roller 8, 8',
Since the engagement point of the cam 2, 2'3 that engages with the cam 17 moves from the high part to the low part by one position, the parallelogram link mechanism 30 is formed as shown in FIG. 1 where the gear 14' and the drive gear 25' mesh The storage box 15 swings about the shafts 6 and 7 as fulcrums to the ejection position indicated by the chain line, but at this time the storage box 15 remains horizontal.

When the parallelogram link mechanism 30 swings, the part of the cam 20 that engages with the roller 23 moves from the high part to the low part, so the activation fitting 21 is moved in the direction of arrow C (with the fixed shaft 22 as a fulcrum). It oscillates counterclockwise in Fig. 1)).

On the other hand, the rear end (right side in FIG. 1) I of the transport medium storage box 15
This is provided with a notch into which the activation fitting 21 can fit.

Therefore, the activation metal fitting 21, which swings as described above, is inserted into this notch at the end of the swing, and the medium 40 accommodated in the transfer medium storage box 15 is sent out from the rear end, and the roller 12
, 12'.

On the other hand, the feed roller 12' is connected to the gear 1 by the drive gear 25'1.
4' and the shaft 13' in the counterclockwise direction in FIG. It is ejected in one direction.

When the drive shaft 1 is then rotated another 180 degrees, the cams 2, 2' engage with the respective rollers 8, 8', 17.

3 moves from the lower part to the higher part, so the parallelogram link mechanism 30 swings from the ejection position to the suction position. Due to the urging force, the gear 14 and the drive gear 25 are smoothly engaged.

Note that during this swing, the cam 2 that engages with the roller 23
The engagement point 0 moves from the lower part to the higher part, and the activation metal fitting 21 swings in the direction of arrow C'.

Thereafter, by repeating this operation, it is possible to sequentially change the direction of the medium being transferred in the direction of the arrow B and discharge it in the direction of the arrow B'.

Note that rollers may be used instead of gears.

As described above, according to the present invention, the transport medium that is being transported forward can be moved downward and then discharged by changing the direction (this direction), and the operation is reliable and the structure is simple. It is possible to achieve various excellent effects.

In particular, terminal devices with limited installation space (this is ideal).
