Description

[Detailed Description of the Invention] This invention relates to a stamp mechanism attached to a card reader for stamping a card after information has been read.

Generally, after the card information is read by the reader,
2. Description of the Related Art A card reader shown in FIG. 1, for example, is conventionally known as a card reader equipped with a stamp mechanism for stamping a reading confirmation stamp.

To explain this card reader, a card 1 passes through a card transport path 4 made up of a base 2 and a guide 3, and is sent forward (leftward in FIG. 1) by first feed rows 25, 5. .

A reading section 6 for reading information recorded on the card 1 is provided in front of the first feed rollers 5, 5, and the card 1 is fed into the reading section 6.

Further, second feed rollers 7, 7 are provided in front of the reading unit 6, and the card 1 after the information has been read by the reading unit 6 is further sent forward and sent to the second feed rollers 7, 7. I can do it.

This is in front of the second feed rollers 7, 1, and the base 2
A stop spring 8 is provided on the top, and a second feed roller γ,
The card 1 sent out through the card 1 stops while pressing the stop spring 8.

Then, a microswitch (not shown) is turned on by the stop spring 8 and a signal is output.

Therefore, the solenoid 9 is energized, and the link 10 rotates around the fulcrum 10a in response to the driving force of the solenoid 9. In conjunction with this, the stamp 11 attached to the link 10 rotates and the stamp 11 is read onto the card 1. The seal will be stamped.

When this stamping operation is completed, the signal is automatically turned off, the solenoid 9 is demagnetized, and the link 10 and stamp 11 return to their original states.

The card 1 stamped in this way is transferred to the second feed row 2.
The card is pushed out by the next card sent out from 7, 7 and discharged to the stacker 12.

However, according to the above-mentioned stamp mechanism, since the link 10 is driven by the solenoid 9, an electric circuit and a mechanical configuration are required, which complicates the structure and causes failures.Furthermore, the manufacturing cost is high. It had costly problems.

This idea was made in view of the above-mentioned circumstances, and its purpose is to have a simple structure, fewer failures, and
Moreover, it is an object of the present invention to provide a stamp mechanism in a card reader that can be manufactured at low cost.

In order to achieve this purpose, a driving roller is provided in the card conveyance path formed between the base and the guide, and the driving roller is biased to abut against this driving roller, and when the card is fed, the card's thickness is , a displaceable driven roller is provided,
The stamp is attached to the arm member that supports the driven roller via an elastic member, and a stop spring is attached to the base, a part of which projects into the card conveyance path and which normally comes into contact with a part of the elastic member.

An embodiment of this invention will be described below with reference to FIGS. 2 to 5.

In addition, in the explanation, the parts that overlap with the above explanation are indicated by the same reference numerals, and the part on the right side of the reading section 6 in the figure is the first one.
Since it is exactly the same as the case shown in the figure, it is not shown in the figure.

In FIG. 2, a driving roller 21 is provided in front of the reading unit 6, and is arranged so that a part of the peripheral surface of this driving roller is on the same plane as the base 2.
A rotational drive mechanism (not shown) is connected to the main drive roller 21, and normally, the main drive roller 21 receives the driving force of this rotational drive mechanism and moves as shown in the figure.
It is rotating in the X direction.

The driven roller 2 is in contact with the roller surface of the main driving roller 21.
2 is disposed, and one end of an arm member 23 formed into an L-shape is fixed to one end of the rotating shaft 22a of the driven roller 22.

Further, a fulcrum 23a of the arm member 23 is rotatably attached to a card reader body (not shown), and the other end of the arm member 23 is attached to one end of a spring 24.

The other end of this spring 24 is connected to the front of the arm member 23 (in the figure).
A spring 24 is held in a tensioned state and attached to a fulcrum 24a that is located on the left side and protrudes from the card reader main body.

Therefore, the arm member 23 is
This force causes the driven roller 2 to
2 is urged so as to come into contact with the driving roller 21.

In addition, one end of an elastic member 25 is attached to one end of the arm member 23, and this elastic member 25 faces the base 2 and extends toward one side of the main drive roller 21 (the left side of the main drive roller 21 in FIG. 2). The elastic member 25 is stretched out, and a stamp 26 for stamping the card from which information has been read is attached to the other end of the elastic member 25, with the stamp surface 26a facing downward in the figure. There is a predetermined interval between them.

The stopper spring 8 is provided on the base 2 in front of the driving roller 21 and directly below the elastic member 25, and the stacker 12 is provided at the exit of the cart transport path 4'.

The stop spring 8 is attached to the base 2 on the left side of the driving roller 21 in FIG. It is being

Next, the operation of the stamp mechanism described above will be explained.

The card 1 is sent forward by the first feed rollers 5, 5, the information is read by the reading section 6, and the card 1 is placed between the driving roller 21 and the driven roller 22 as shown in FIG.

At this time, the driven roller 22 is in contact with the main driving roller 21, and furthermore, the stamp surface 26a of the stamp 26 is at a position a separated from the base 2.

Next, the card 1 is sent further forward and is sandwiched between the driving roller 21 and the driven roller 22 as shown in FIG.

Then, the driven roller 22 moves to the fulcrum 23 by the thickness of the card.
It rotates in the Y direction together with the arm member 23 about a.

With this rotation, the stamp 26 rises and the stamp surface 2
6a reaches position b, and the spring 24 is further tensioned to accumulate elastic energy.

Next, the card 1 is sent further forward by the driving roller 21, passes between the driving roller 21 and the driven roller 22, and is stopped by the stop spring 8 immediately after passing.

Then, as shown in FIG.
4 to the left in the figure, it rotates in the X direction about the fulcrum 23a.

With this rotation, the driven roller 22 comes into contact with the main driving roller 21, and furthermore, the elastic member 25 and the stamp 26
rotate in the direction.

Therefore, the stamp surface 26a of the stamp 26 moves down from the position b, and the elastic member 25 is an elastic material and the stamp 26
Due to the inertial force, the stamp surface 26a of the stamp 26 passes through the position a, and the stamp surface 26a collides with the card 1 at the C position, and at this time, the card 1 is stamped after being bent.

After the stamping operation is completed, the elastic member 25 undergoes a damped vibration that converges toward the a position, and the stamp surface 26a of the stamp 26 finally stops at the a position.

Here, when the next card passes between the driving roller 21 and the driven roller 22, this card pushes the card 1 onto the stacker 12, and the above-described stamping operation is repeated.

As explained above, the stamp mechanism of this invention does not use any electrical circuits and has an extremely simple structure, so it has the advantage of having fewer failures and being able to be manufactured at low cost.

Furthermore, since the stamp is attached via an elastic member, there are few parts that wear out, and therefore each part can be used for a long period of time and has excellent durability.
