Description

[Detailed description of the invention] Industrial application field The invention is incorporated into, for example, a cache dispenser (CD), and is used for imprinting, which presses and transfers embossed characters formed on a recording card such as a magnetic card onto a pressure sensitive element. Regarding equipment.

Prior Art An imprint device used in a cash dispenser etc., when a magnetic card inserted through the card slot of the cash dispenser comes to the printing position, prints a copy of a vendor (bank, etc.) on or under the card. A journal paper and a customer receipt paper are overlapped, and embossed characters previously formed on a card are transferred to these two papers under pressure. Both the journal paper and the receipt paper are made of pressure-sensitive coloring paper, and are supplied as continuous paper from their respective paper stock sections to the print position via a paper feed mechanism. The imprint device presses a pressure roller against journal paper and receipt paper stacked on a magnetic card placed on an imprint table and rolls the embossed characters a distance corresponding to the area of the embossed characters, thereby printing embossed characters on both sheets. Pressure transfer. However, when the card comes to the print position, that is, onto the imprint stand, or when it is ejected from the print position to the card ejection port after imprinting, the pressure roller is temporarily retracted to avoid interfering with the card. It is necessary to do so. Because of the need to secure a shelter space for such cards, conventional imprint apparatuses have been forced to increase in size, and a solution to this problem has been desired. Furthermore, the conventional imprint apparatus has a complicated structure because it is necessary to reciprocate the pressure roller in the longitudinal direction of the card so as to cover the entire embossed character.

Purpose of the invention The purpose of the present invention is to provide an imprint device that is small and has a simple structure in order to solve the above-mentioned problems.

In order to achieve the above-mentioned object, the present invention eliminates the pressure roller mechanism that moves over the embossed characters on the card and uses a plate-shaped presser that moves in a seesaw motion to solve the problem.

Structure of the invention The imprint device according to the invention transfers embossed characters on a recording card to pressure-sensitive paper between a presser and a platen, and one of the opposing pressing surfaces of the presser and the platen has a convex surface. The presser is supported by a vertically movable pivot to allow seesaw movement, and a pair of rotary cams are lockably provided at both ends of the presser, and these cams generate seesaw movement in the presser. It has a tight cam profile.

Embodiments Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings.

FIG. 1 schematically shows the internal structure of a cache dispenser incorporating an imprint apparatus according to the present invention. First, this cache dispenser will be briefly described.

When a card (not shown) such as a magnetic card is inserted into the card insertion slot 13, several feed drive rollers or guide rollers 10A, 10B, 10C are inserted.
etc., to the imprint station S _I. Before reaching the imprint station _SA , the card passes through a card reader station _SR , where the card reader 15 reads necessary information on the card to confirm the identity of the card. The card has raised letters (embossed letters) on which, for example, the card user's registration number is displayed. Copy paper for businesses (banks, etc.), that is, journal paper 16, is stored as continuous paper on a feed spool 21, and is sent to print station _SP and imprint station _SI via appropriate drive rollers and direction change rollers. and is wound onto the take-up spool 25. On the other hand, receipt paper 18 to be delivered to the customer is stored in a magazine 20, and is cut one by one by a receipt cutter 19 after predetermined printing is performed at a print station _SP and an imprint station _SI . Journal paper 16 and receipt paper 18 are overlapped and printed simultaneously at imprint station S _I and print station _SP . After printing is completed, the card is returned to the card insertion slot 13 through the same place as the outward path. The journal paper 16 is wound up on a take-up spool 25, while the receipt paper 18 is cut by a receipt cutter 19, passes through a reject gate 24 and a return path 22, and the receipt and card merge before the 10A roller and the card is inserted. It is returned to the mouth 13.

The present invention relates to an imprint device (imprint station S _I ) that is incorporated into, for example, the above-mentioned cache dispenser.

As shown in FIGS. 2 and 3, the imprint apparatus according to the present invention includes a platen 41 that forms a passage for cards 31, receipt paper 18, and journal paper 16.
and a presser 43. These platen 41 and presser 43 are connected to a pair of frame plates 50, 5.
It is provided between the two. The presser 43 has a pressing surface 42 that is curved in a convex manner toward the platen 41 . In the illustrated embodiment, the presser 43 has a convex pressing surface 42, but the receiving surface 40 of the platen 41 may alternatively be made convex. The pusher 43 is in the card advancing direction D.
The support arm 47 is located approximately in the center of the pusher 4 as seen in the figure.
3 is capable of see-saw movement around a pivot 49 of a support arm 47. The support arm 47 is approximately L-shaped as shown, and the other end is rotatably supported by a pivot shaft 51. The pivot 51 is the plate 5
Fixedly installed between 0 and 52. Pivot 51 of support arm 47
There is a detection lever 53 rotatable together with the support arm 47.
is supported. The detection lever 53 detects the end of the imprint operation by having its free end engaged with a sensor 55 such as a micro switch, and its operation will be described later.

A pair of rollers 59 and 61 functioning as cam followers are rotatably supported by shafts 58 and 62 at the lower portions of both ends of the presser 43 . These rollers 59, 6
Eccentric cams 63 and 65 are respectively engaged with 1. The eccentric cams 63 and 65 may have the same shape, but their phases are shifted by, for example, 90 degrees. Therefore, when the cams 63 and 65 simultaneously rotate in the same direction, the pusher 43 swings left and right and performs a seesaw motion. Become. That is, the cams 63, 65 have a profile that allows a see-saw movement of the support arm 47. The cams 63 and 65 are rotatable around respective shafts 71 and 73, and on the other hand, for example, the cam 63 is connected to a drive gear (worm) 79 of the motor M via a gear 75 fixed to the shaft 71. be done. On the other hand,
The cam 65 is connected to the cam 63 via, for example, a belt 81 extending between the shafts 71 and 73.
It can also be rotated.

A third cam 83 is connected to the shaft 73 of the cam 65.
The detection lever 53 is rotated clockwise in FIG. 2 about the shaft 51 via the detector 54 of the detection lever 53 every rotation of the shaft 73, and the sensor 55 is turned on. As a result, sensor 55 sends a stop signal to motor M to stop it. When the detector 54 of the detection lever 53 disengages from the cam lobe of the third cam 83, the detection lever 53 is rotated counterclockwise in FIG.
1 in the counterclockwise direction to bring the presser 43 to the 43' position. The pusher 43 is made vertically movable in this way so that the card 31, journal paper 16, and receipt paper 18 can be easily brought to the imprint position, that is, between the platen 41 and the pusher 43. . That is, when the card 31, journal paper 16, and receipt paper 18 are inserted into the imprint position and taken out from the imprint position, the presser 43 is at the lower position shown by the solid line in FIG. It is located at the upper position indicated by '. Note that the card 31 and the sheets 76 and 18 are supported at both edges by carriers (not shown), and therefore the presser 43
It is held at the predetermined position shown in the figure regardless of its vertical position.

When the presser 43 is in the upper position, the roller 5
9 and 61 are separated from the respective eccentric cams 63 and 65, so that when the eccentric cams 63 and 65 are located above the presser 43, the largest cam lobe portion is located above the roller 5.
It has a cam profile of such a size that it comes into contact with 9, 61 and causes a seesaw movement of the presser 43. That is, when the presser 43 is in the upper position,
The eccentric cams 63 and 65 alternately move the corresponding rollers 59 and 61 only within a predetermined angular range according to their rotation.
, and causes the presser 43 to seesaw motion. This seesaw movement of the presser ensures that the embossed characters 32 on the card 31 are transferred to the journal paper 16 and the receipt paper 18 under pressure. That is, the presser 43 presses the embossed characters 3 while gradually shifting the pressing position by the action of the pair of eccentric cams 63 and 65.
2 is strongly pressed against the receiving surface 40 of the template 41 via the journal paper 16 and the receipt paper 18 to transfer the embossed characters 32 onto these papers. Although it is possible to feed the sheets 16 and 18 in the same direction as the card 31, in the illustrated embodiment, it is assumed that the sheets 16 and 18 are fed from the F direction (FIG. 3), which is orthogonal to the card feeding direction D. . Also, 9
Reference numeral 1,93 is a C-ring that prevents it from coming off.

The third cam 83 detects the detection lever 53 when the cams 63, 65 make one revolution and the presser 43 finishes its seesaw movement once in such a way that the pressurizing position is continuously shifted from the left end to the right end, for example. Detector 5
The cam profile and the phase of the third cam 83 relative to the eccentric cams 63 and 65 are determined so as to turn the detection lever 53 clockwise in FIG. 2 and turn on the sensor 55 by pressing 4.

Effects of the Invention As described above, according to the present invention, embossed characters on a card can be pressure-transferred onto pressure-sensitive paper in a reliable manner using a simple and compact imprint device.
