BACKGROUND OF THE INVENTION
The present invention relates to a technique for preventing malfunction due to magnetic noise of a manual magnetic card reader and damage due to dropping or the like.
[0002]
[Prior art]
[0003]
Among magnetic card readers that read information recorded on magnetic cards, especially magnetic card readers that are used in read-only systems have a simple configuration, so magnetic cards that have been slid and moved by human operations are magnetic. A manual type that reads information is conventionally used.
[0004]
8 and 9 show the configuration of a conventional manual type magnetic card reader 10. A casing 11 made of synthetic resin has a slit 12 slightly wider than the thickness of the magnetic card 1 on one side. It is formed in a straight line so as to continue from the side surface to the other side surface.
[0005]
A reader unit 13 is fixed inside the housing 10. The reader unit 13 includes a base 14 made of synthetic resin and a magnetic head 18 attached to the base 14.
[0006]
The base 14 includes a substantially rectangular substrate 15 and a pair of guide plates 16 and 17 erected in parallel on the upper surface side of the substrate 15 so as to face each other with an interval slightly wider than the thickness of the magnetic card 1. The gap between the pair of guide plates 16, 17 coincides with the slit 12 of the housing 11, and the magnetic card 1 slid along the slit 12 is in contact with the upper surface of the substrate 15 with the guide plate 16, It is being fixed to the bottom part of the housing | casing 10 so that between 17 may be passed.
[0007]
At least one of the guide plates 16 and 17 (here, the guide plate 16), the magnetic head 18 has a magnetic stripe (not shown) on the surface of the magnetic card 1 passing through the gap between the guide plates 16 and 17 on the head surface 18a. ) And is attached in a protruding state so as to contact.
[0008]
In the magnetic card reader 10 configured as described above, the magnetic card 1 inserted into the slit 12 is slid while being guided between the guide plates 16 and 17 of the reader unit 13 and recorded on the magnetic card 1. Magnetic information is read by the magnetic head 18 and the read signal is output to a circuit unit including a waveform shaping circuit (not shown).
[0009]
[Problems to be solved by the invention]
However, since the slit 12 and the reader unit 13 of the magnetic card reader 10 are often provided on one end side of the housing 11, they are easily affected by external magnetic noise, and devices using a motor or the like can be brought close to each other. There was a problem that I could not.
[0010]
Further, in the conventional magnetic card reader 10 described above, the casing 11 made of synthetic resin is divided into two parts with the slit 12 leaving the bottom, and the base 14 of the reader unit 13 is also made of synthetic resin. There has been a problem that a failure such as cracking of the casing 11 along the slit 12 and deformation of the reader unit 13 is likely to occur due to an impact such as time.
[0011]
An object of the present invention is to solve this problem and to provide a magnetic card reader that is not easily affected by magnetic noise from the outside and that is unlikely to cause a failure such as dropping.
[0012]

The screw 55 may be tightened through the screw 28 and the screw hole 29 of the front plate 23a of the upper case 23. Even in this case, the magnetic noise from the front end side of the main body 21 can be shielded by the reinforcing member 40, and the magnetic card can be reliably read even when another device that generates the magnetic noise approaches.
[0035]
In this embodiment, the present invention is applied to the magnetic card reader of the handy terminal 20, but the present invention can be similarly applied to a single magnetic card reader.
[0036]
In this case, for example, as in the magnetic card reader 70 shown in FIGS. 6 and 7, a third plate portion 46 facing the second plate portion 42 is provided, and the reinforcing member 40 ′ is formed in a U shape. The upper case 72 can be firmly fixed to the lower case 71, and similarly to the above, there are no problems such as case cracking due to impact such as dropping or deformation of the reader unit 30. Further, magnetic noise from both sides of the housing can be shielded.
