Description

[Detailed explanation of the idea] 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. In this type of magnetic card processing device, in order for the magnetic card to slide smoothly, the width of the card running path must be set slightly larger than the thickness of the magnetic card. Furthermore, in order to perform accurate reading and writing, the magnetic printing part of the magnetic card and the magnetic head must be in close contact. For this reason, in the past, a rectangular hole was bored in the side plate constituting the card running path, and the magnetic head, which was disposed so as to slightly protrude from the hole into the card running path, was supported by a leaf spring. Was. However, in such conventional magnetic card processing devices, the length of the leaf spring inevitably increases in order to impart sufficient elastic force to the magnetic head, resulting in an increase in the size of the entire device or an increase in internal space. It was becoming less efficient.

In view of these circumstances, the present invention uses a specially shaped plate spring with a small overall length to support the magnetic head, and incorporates this into the housing body in a simple manner, thereby reducing the size of the device. , a magnetic card processing device that has achieved improved accuracy, has engagement grooves located on the inner surface of the card guide hole formed by vertically dividing the housing body and on the inner surfaces of both side plates of the housing body. A pair of studs with holes are erected integrally between the notch holes drilled in the side plate, which is assembled by inserting both ends into the engagement grooves.
It is shaped like a letter, and has a cutout hole in the center portion into which a magnetic head is fitted and supported so that the head portion protrudes from the cutout hole into the card running path, and the two end portions folded back toward the center are provided with the cutout hole into which the magnetic head is fitted and supported. It is characterized by having a leaf spring with a hole corresponding to the stud.

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

A flange 14 having a width approximately equal to the thickness of each side plate of the housing body 1 is formed on the periphery of the housing base 13, and the flanges 14A and 14B on both sides in the longitudinal direction are further extended to form a long hole 15. It is configured as an attachment part when attaching this device to the main device. Further, a plurality of convex portions 16 are integrally provided on the housing base 13 and are located on the same axis corresponding to the card guide hole 5 at the center position in the width direction thereof. Of course, the housing base 13 is provided with a plurality of through holes 17 corresponding to each of the studs 10 to 12 of the housing body 1, and the housing body 1 and the housing base 13 are integrally connected by set screws 18. are combined. Note that 19 is a lead wire pulling groove cut into one side of the housing base 13. 20 and 26 are running path side plates forming the card running path H. These running road side plates 20, 26 are made of a synthetic resin material and are formed into a plate shape, and their length is determined by the opposing distance between the side plates 3, 4 of the housing body 1, and their height is determined by the distance between the opposite side plates 3, 4 of the housing body 1. The distance between the upper plate 2 of the main body 1 and the convex portion 16 is set to be approximately equal to the distance between the upper plate 2 and the convex portion 16 . Further, at both ends of these running road side plates 20, 26, there are engaging protrusions 2 that are engaged with the engaging grooves 6, 8 and 7, 9, respectively.
1, 22 and engaging protrusions 27, 28 are integrally formed. Therefore, the running road side plate 2
0 and 26, the engagement protrusions 21 and 22 and the engagement protrusions 27 and 28 are connected to the corresponding engagement grooves 7 and 9, respectively.
The housing body 1 is assembled into the housing body 1 by being inserted into the engagement grooves 6 and 8 and engaged with each other.
The assembled running road side plates 20, 26 are

The track plate 31 is also molded from a synthetic resin material, and its length is approximately equal to the opposing spacing between the side plates 3 and 4 of the housing body 1, and its width is approximately equal to the opposing spacing between the running track side plates 20 and 26. It is formed slightly larger than the A pair of engaging protrusions 32 and 33 are integrally protruded from both ends of the approximately central portion of the track plate 31, and a rail piece 31A is joined to the surface thereof. This rail piece 31A is molded from a synthetic resin material containing glass fiber mixed with a lubricating oil such as molybdenum. The track plate 31 is connected to the engaging protrusions 32, 3.
3 clamps both side surfaces of the running road side plates 20, 26, and both ends thereof are the side plates 3, 4 of the housing body 1.
By coming into contact with the running road side plate 2
0,26, thus forming the bottom of the card running path H. The track plate 31 assembled in this manner is placed on the convex portion 16 and held by the housing base 13. 34 is a magnetic head, and its head surface 35
is supported on the card running path side plate 20 so as to protrude into the card running path H. That is,
The magnetic head 34 is attached to a mounting hole 37 provided in the leaf spring 36.
After being inserted and assembled, it is fixed with epoxy resin or the like. The leaf spring 36 has a substantially C-shape with both ends bent toward the center, and the bent ends 38 and 39 have transparent holes corresponding to the holed studs 24 and 25. Holes 40 and 41 are drilled, respectively. By fixing this plate spring 36 onto the studs 24 and 25 via the mounting screw 42, the head surface 35 of the magnetic head 34 faces into the card running path H from the notch hole 23. . Engagement steps 29 and 30 are formed on both side surfaces of the running road side plate 26. As shown in FIG. Reference numeral 43 denotes a printed circuit board on which electrical and electronic components are mounted, and its length dimension is the same as that of the engaging step portions 29 and 3.
The opposing spacing is approximately equal to 0. Therefore, the printed circuit board 43 is assembled to the side surface of the running road side plate 26 by inserting and engaging both ends into the engaging steps 29 and 30. Further, the assembled printed circuit board 43 is held by studs 10 and 11 that engage with the side surfaces thereof.

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. The engaging protrusions 27 and 28 are engaged with the grooves 6 and 8, and the running road side plate 26 is inserted and assembled. Incidentally, a magnetic head 34 is previously assembled to the road side plate 20 via a leaf spring 36. Next, the running road side plate 2 is assembled to the housing body 1.
0,26, the track plate 31 is attached to its protruding pieces 32,3.
Assemble using 3. After that, the engagement step portion 2
9 and 30 by engaging both sides of the printed circuit board 43.
is inserted into the side surface of the running road side plate 26 and assembled. Thus, the housing base 13 may be assembled to the bottom of the housing body 1 and fixed using the setscrews 18. Incidentally, maintenance etc. 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 purpose, magnetic card C and running road side plates 20, 2 are used.
However, since the magnetic head 34 is projected into the card running path H and is supported by the leaf spring 36, the head surface 35 of the magnetic head 34 is connected to the magnetic printing part of the magnetic card C. be sure to scan. 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 need to have 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 magnetic head is supported by a leaf spring, so the width of the card running path is made slightly larger than the thickness of the magnetic card. Even if smooth sliding is performed, the head surface of the magnetic head reliably scans the magnetic printing portion of the magnetic card to read or write information. In addition, since both ends of the leaf spring are bent toward the center and the whole is formed into a C-shape, the installation space can be made more efficient even though the leaf spring has an elastic force corresponding to the length of the leaf spring. This results in a reduction in the size of the device as a whole. In addition, the magnetic bed is attached to the running road side plate via studs that are integrally installed upright thereon, and the running road side plate is assembled by being inserted into the engagement grooves provided on the inner surfaces of both side plates of the housing body. It is extremely easy to assemble, and the position and dimensions of the magnetic head can be accurately set with respect to the card running path, which together with the effect of the elastic force of the leaf spring mentioned above, improves the precision of the device.
