Description

[Detailed Description of the Invention] This invention relates to a magnetic card drive device that transports a magnetic card for reading and writing data.

A magnetic head that reads and writes to a magnetic card is provided with a pressure roller that brings the card into contact with the magnetic head.When this pressure roller is provided in an idle state, it transports the magnetic card. Due to the speed difference between the conveyor belt and the
This method has the disadvantage that the magnetic card cannot be conveyed smoothly and errors occur when reading or writing data.

For this purpose, the above-mentioned mistake can be solved by providing the above-mentioned pressure roller to be driven at the same speed as the conveyance speed. Furthermore, if an input pulley is provided on the pressure roller shaft and a belt is stretched around these pulleys, and the outer diameter of the output pulley and input pulley described above is made to be the same as the conveyance speed, these pulleys can be There are speed fluctuations due to manufacturing errors, and there are also speed fluctuations due to belt slips and belt stretching and contraction due to load, so it is very difficult to keep the conveyance speed and the pressure roller speed the same from beginning to end. It was difficult.

Therefore, the object of this invention is to provide a magnetic card drive device that can easily equalize the magnetic card conveyance speed of the magnetic card conveyance belt and the driving pressure roller disposed opposite to the magnetic head.

According to this invention, the shaft ends of the drive pulley shaft of the conveyor belt and the drive press roller shaft disposed opposite to the magnetic head are extended to one side of the conveyance path, and two rollers are attached to these extending shafts. Since a single drive belt is stretched across the two input pulleys and the motor output pulley to transmit the drive, the number of pulleys that require manufacturing precision is reduced, and speed fluctuations due to manufacturing errors are extremely minimized. can do. Furthermore, since one drive belt is shared, even if this belt stretches or contracts due to load, the effect will be the same on the two input pulleys. Speed fluctuations can be completely eliminated, and as a result, good magnetic reading and writing can be achieved.

Further, since the input pulley and the drive belt that drive the driving pressure roller are provided on one side of the magnetic card conveyance path, the conveyance path is simplified and the maintenance and management of this conveyance path is facilitated.

In addition, since the number of parts in the power transmission system is reduced, mechanical response during forward and reverse rotations is ensured, and costs are reduced.

As also shown in FIG. 3, the above-mentioned magnetic head 30
A drive pressing roller 31 is opposed to the roller 31, and this roller 31 is driven at the same speed as the conveyance speed of the aforementioned conveyance belts 3 and 4, and is configured to grip and convey a magnetic card (not shown). It has the function of

That is, a lever base 34 is pivotally attached to the inside of a shaft 33 supported by a boss 32 integrally formed on the outer surface of the main fixed wall 1, and the lever base 34 has two inner and outer sides facing the magnetic head 30 side. book lever 3
A shaft 37 is supported between the free ends of these levers 35 and 36, and the aforementioned drive pressing roller 31 is fixed to this shaft 37.

The bearing portion 38 of the inner lever 35 described above fits into a notch 39 of the main fixed wall 1, and this notch 39 is formed in a size that allows the bearing portion 38 of the inner lever 35 to move up and down. There is.

The adjustment screw 40 provided on the upper surface of the main fixed wall 1 has its lower end (not shown) connected to the inner lever 35 mentioned above.
The upper limit of movement of the drive pressing roller 31 is restricted by contacting the bearing portion 38 of the drive pressing roller 31 .

The aforementioned lever base 34 has the aforementioned lever 35,
A locking lever 41 is connected in a direction opposite to 36,
This locking lever 41 and the main fixed wall 1 at this lower position
A spring 42 is tensioned between the magnetic head 30 and the magnetic head 30, and the spring 42 urges the drive pressing roller 31 toward the magnetic head 30.

The shaft 37 to which the aforementioned drive pressing roller 31 is fixed extends outward from the main fixed wall 1, and a second input pulley 43 is fixed to this extending portion.

Note that 44 in the figure is a lower guide plate on the insertion side of the magnetic card.
