DETAILED DESCRIPTION OF THE INVENTION The present invention relates to improvements in magnetic card processing devices.
2. Description of the Related Art A magnetic card processing device is known in which a magnetic card is inserted into a card running path whose top and both sides are open and the card is slid to read or write information on the magnetic card. Conventionally, this type of magnetic card processing device has assembled card running path constituent members on a base frame formed of a metal plate material so as to face each other in parallel.
Furthermore, the whole thing was covered with a cover. According to such a conventional card processing device, although the cover does not require much dimensional accuracy, the base frame or the card running path constituent members must be manufactured with extremely high precision. A magnetic head is attached to the card running path constituting member, and a printed circuit board on which electronic and electrical components are mounted is attached to the base frame, and then both are assembled by screwing or the like. As described above, the assembly process is troublesome, and even if parts are manufactured with high precision, assembly errors occur, and adjustments are required after assembly is completed. Further, due to the troublesome assembly, maintenance etc. are troublesome and require considerable skill.

In view of these circumstances, the present invention provides a magnetic card processing device in which each constituent member has an extremely simple shape and the assembly is significantly streamlined.
A magnetic card processing device according to the present invention that achieves this object is provided with a case-like housing main body having a card guide hole into which a magnetic card is inserted and runs, and a high By inserting and engaging both ends into the engaging grooves, the pair of card running path side plates are incorporated into the housing body, and the lower edge of the card running path side plates is further fitted with a track. The present invention is characterized in that a card running path is formed below the card guide hole by assembling a plate.

Hereinafter, the present invention will be explained in detail with reference to embodiments shown in the drawings.

In the figure, reference numeral 1 denotes a housing body molded from a synthetic resin material. This housing body 1 is a case-like body with an open bottom, and a card guide hole 5 is provided by splitting this housing body longitudinally across a top plate 2 and both side plates 3 and 4.
A pair of engagement grooves 6, 7 and 8, 9 are formed on the inner surfaces of both side plates of the housing body 1 so as to be located on both sides of the card guide hole 5.
A plurality of studs with holes 10 to 12 are integrally provided downward on the inner surface of the upper plate 2. The studs 10, 11 provided on the side of the engagement grooves 6, 8 are provided at a predetermined distance from the card guide hole 5. Reference numeral 13 denotes a housing base which covers the open bottom of the housing body 1.
The housing base 13 is made of a synthetic resin material and is generally plate-shaped. A flange 14 having a width substantially equal to the thickness of each side plate of the housing body 1 is formed on the periphery of the housing base 13. The flanges 14A and 14B on the longitudinal sides are further extended to form a long hole 14.
The housing base 13 is provided with a plurality of protrusions 16 which are formed integrally with the housing base 13 at the center in the width direction and are positioned on the same axis as the card guide hole 5. Of course, the housing base 13 is provided with a plurality of through holes 17 which correspond to the studs 10 to 12 of the housing main body 1, and the housing main body 1 and the housing base 1 are fastened to each other by set screws 18.
3 are integrally joined. Reference numeral 19 denotes a lead wire pull-out groove cut into one side of the housing base 13. Reference numerals 20 and 26 denote runway side plates which form the card runway H. These runway side plates 20, 26 are formed as whole plates from a synthetic resin material, and their length dimension is set to be approximately equal to the opposing distance between the side plates 3, 4 of the housing body 1, and their height dimension is set to be approximately equal to the opposing distance between the upper plate 2 of the housing body 1 and the protrusion 16. Furthermore, the runway side plates 20, 26 have the engagement grooves 6, 8 and the engagement grooves 7,
9, engaging protrusions 21, 22 and engaging protrusions 27, 28 which are engaged with the respective engaging portions 9 are integrally formed.
Therefore, the running road side plates 20, 26 have their engaging flanges 21, 22 and engaging flanges 27, 28.
The plates 20, 26 are assembled to the inside of the housing body 1 by inserting them into and engaging with the corresponding engaging grooves 7, 9 and 6, 8, respectively. The distance between the assembled runway side plates 20, 26 is approximately equal to the width of the card guide hole 5. In other words, the upper edges of the plates 20, 26 are joined to the inner surface of the top plate 2 of the housing body 1 along the wall of the card guide hole 5.
Thus, these roadway side plates 20, 26
As a result, a card guide path H is formed below the card guide hole 5.
One of the track side plates 20 has a rectangular cutout hole 23 drilled in its approximate center, and a pair of holed studs 24, 25 are integrally formed on its side so as to sandwich the cutout hole 23. These studs 24, 25 are provided for mounting a magnetic head 34, which will be described later. A track plate 31 is attached to the lower edges of the track side plates 20, 26. The track plate 31 is also made of synthetic resin material, and
The length of the housing body 1 is
The width of the track plate 31 is formed to be slightly larger than the distance between the track side plates 20, 26. The track plate 31 is provided at both ends of the track side plate 31 at the center thereof with a pair of engaging projections 32,
33 is integrally provided and a rail piece 3 is provided on the surface.
The rail piece 31A is joined to the rail piece 31A.
The track plate 31 is molded from a synthetic resin material containing glass fiber mixed with a lubricant such as molybdenum. The track plate 31 is assembled to the lower edges of the track side plates 20, 26 by the engaging protrusions 32, 33 clamping both sides of the track side plates 20, 26 and abutting both ends against the side plates 3, 4 of the housing body 1, thereby forming the bottom of the card track H. The track plate 31 assembled in this manner is placed on the protrusions 16 and held by the housing base 13. 34 is a magnetic head, which is supported on the track side plate 20 so that its head surface 35 protrudes into the card track H. That is, the magnetic head 34
The plate spring 36 is fitted into a mounting hole 37 formed in the plate spring 36, and then fixed with epoxy resin or the like. The plate spring 36 has both ends bent toward the center to form a C-shape, and the holed studs 24, 25 are attached to the bent ends 38, 39.
The plate spring 36 is fixed to the plate 32 by means of a mounting screw 42.
The magnetic head 34 is fixed on the studs 24, 25 via the head surface 35.
faces into the card running path H through the notch hole 23. Engagement steps 29, 30 are formed on both edge side surfaces of the running path side plate 26. Reference numeral 43 denotes a printed circuit board on which various electric and electronic components are mounted, and its length dimension is formed to be approximately equal to the opposing distance between the engagement steps 29, 30. Therefore, the printed circuit board 43 is assembled to the side surface of the running path side plate 26 by inserting and engaging both ends with the engagement steps 29, 30. The assembled printed circuit board 43 is held in place by the studs 10, 11 which engage with the side surfaces of the printed circuit board.

A lead wire (not shown) connecting the magnetic head 34 and the printed circuit board 43 is inserted into a gap formed between the protrusion 16 of the housing base 13 and the lower surface of the track plate 31.

The assembly process of each member configured as described above will be explained below.

First, the housing main body 1 is placed with its open bottom facing upward, and then the engaging protrusions 21 and 22 are engaged with the engaging grooves 7 and 9, and the running road side plate 20 is also engaged. Engaging protrusions 27 in the matching grooves 6 and 8;
28 and insert and assemble the running road side plate 26. Incidentally, a magnetic head 34 is previously assembled to the road side plate 20 via a leaf spring 36. Next, the track plate 31 is assembled to the running road side plates 20 and 26 assembled to the housing body 1 using the projecting pieces 32 and 33 thereof. Thereafter, the printed circuit board 43 is inserted into the side surface of the running road side plate 26 by engaging both side edges with the engaging stepped portions 29 and 30, and is assembled. Thus, the housing base 13 may be assembled to the bottom of the housing body 1 and fixed using the setscrews 18. Note that maintenance and the like can be carried out by reversing the above-mentioned procedure.

When the magnetic card processing device assembled in this way reads information on the magnetic card C or writes information therein, the magnetic card C is inserted from one end of the card guide hole 5 into the card running path H.
Insert it inside and slide it towards the other end.
As described above, the rail piece 31A is joined onto the track plate 31, and the magnetic card C slides smoothly due to the material properties of this rail piece. Of course, the width of the card guide hole 5, in other words, the card running path H, is set to be somewhat larger than the thickness of the card in order to ensure smooth sliding of the magnetic card C. For this reason, a gap is created between the magnetic card C and the running path side plates 20, 26, but by protruding the magnetic head 34 into the card running path H and elastically supporting it by the leaf spring 36, the magnetic head can be removed. The head surface 35 of 34 reliably scans the magnetic printing portion of the magnetic card C. The elastic force of the leaf spring with the magnetic head 34 provided approximately at the center and fixed at both ends is determined by its material properties and the distance between the fulcrum and the point of action. Therefore, in order to obtain a predetermined elastic force, a simple plate-like object would require a certain length, but in the example device, it is a simple plate with both ends bent. By using the C-shaped leaf spring 36, space efficiency can be improved.

As explained in detail above, according to the present invention, the housing main body, the pair of running road side plates, and the track plate constituting the card running path are assembled by a simple insertion method, and the assembly process is faster than that of conventional devices. , or a significant streamlining of maintenance work is achieved. Furthermore, since this is an assembly method that does not involve screwing, assembly errors are small and there is no need for troublesome adjustment work after assembly. Further, in the case of components molded from synthetic resin materials, so-called self-tap screws are used, so disassembly and assembly cannot be performed.However, the present invention does not have such inconveniences and has extremely great practical effects.
