Description

[Detailed description of the invention] The present invention relates to the installation of the magnetic passbook reading unit in a device having a magnetic medium reading unit such as a magnetic passbook, and the present invention relates to the installation of the magnetic passbook reading unit on the upper cover of the magnetic passbook reading unit attached to the lower cover at the bottom of the device. This relates to a positioning mechanism.

Conventionally, the magnetic passbook reading unit 1 of a recording device as shown in FIG. It is done by covering it with

In addition to the keyboard 3 and magnetic bankbook reading unit 1 mounted as described above, a printed circuit board (not shown) for controlling them is mounted on the lower cover 2.

Therefore, when the upper cover 4 is attached, a cutout window 5 is provided in the upper cover 4 so that the key tops of the keyboard 3, the magnetic bankbook reading unit 1, etc. are exposed to the outside of the upper cover 4 and can be operated.

When attaching the upper and lower covers 2 and 4, due to variations in the accuracy of each component, etc., the positions of the keyboard 3 and magnetic bankbook reading unit 1 attached to the lower cover 2 and the cutout window 5 provided in the upper cover 4 may be changed. The opposing sides did not match and were lopsided.

Therefore, by shifting the position of the upper cover 4,
It is very complicated to simultaneously adjust the clearance between the magnetic passbook reading unit 1 and the key tops of the keyboard 3.

Further, a printed circuit board for controlling the magnetic passbook reading unit 1, etc. is installed below the magnetic passbook reading unit 1, and the gap a between the magnetic passbook reading unit 1 and the upper cover 4 is
There is a problem in that foreign objects such as dust and paper clips fall onto the printed circuit board.

Note that the exposure of the magnetic passbook reading unit 1 is not desirable in terms of the appearance of the recording device, and a smart design is also required.

The purpose of the present invention is to solve the above-mentioned problems by providing a mechanism for fixing the magnetic passbook reader by covering the upper cover with the magnetic passbook reading unit attached to the lower cover.

A feature of the present invention is that the magnetic medium reading unit is provided with a tapered part, and the upper cover is provided with a tapered part that fits with the tapered part of the magnetic medium reading unit at a position facing the magnetic medium reading unit, and The above objective is achieved by attaching the medium reading unit and the bottom via a leaf spring.

FIG. 2 is a plan view (A), a front view (front view), and a side view (C) for explaining the magnetic bankbook reading unit according to the present invention.

FIG. 3 is a sectional view showing an embodiment of a mechanism for fixing the magnetic bankbook reading unit to the upper cover according to the present invention.

In the figure, tapered parts 8 and 9 are provided on the outer periphery of a magnetic passbook reading unit 6 made of resin or the like, and a plurality of mounting holes 1 are provided in the lower part.
0, and a magnetic passbook insertion groove 11 is provided at the center of the thickness of the magnetic passbook reading unit 6, and a plate 12 is provided at the bottom of the groove 11.
is installed.

Further, a spring 15 that presses the magnetic head 13 and the magnetic passbook 14 is provided inside the groove 11, and the magnetic passbook 14 is held in place by the reading unit 6.
Reading is performed by sliding the magnetic passbook 14 on the plate 12 from the right side to the left side of the insertion groove 11 and pressing the magnetic passbook 14 against the magnetic head 13 side by the spring 15.

In accordance with the tapered parts 8 and 9 of the magnetic passbook reading unit 6, the upper cover 4' made of resin or the like is provided with a tapered part as shown in FIG. The upper cover 4' is placed over the magnetic bankbook reading unit 2' so that the tapered portions 8 and 9 of the magnetic passbook reading unit 6 are integrated with the tapered portion of the upper cover.

The taper of the magnetic passbook reading unit 6 may be only on one side.
The taper of the upper cover is also only on one side.

Further, a mounting shaft 16 is provided on the lower cover 2' facing the plurality of mounting holes 10 provided at the lower part of the magnetic passbook reading unit 6, and is fitted with the mounting holes 10 with a large gap.
A plate spring 15 as shown in the figure is attached to the shaft 16, the shaft 16 is inserted into the mounting hole 10 of the magnetic passbook reading unit 6, and the spring pressure of the plate spring 15 is used to generate the magnetic The passbook reading unit 6 is fixed.

When attaching the upper cover 4' to the lower cover 2' made of resin or the like, align the tapered part of the upper cover 4' with the tapered parts 8 and 9 of the magnetic passbook reading unit 6, and then attach the upper cover 4' to the lower cover 2' made of resin or the like.
(see Figure 1). Next, move the upper cover 4' to adjust the facing of the keyboard 3 and the keyboard cutout window 5 of the upper cover 4', and then remove it from the bottom of the lower cover 2'. It is fixed with screws (not shown).

In the above case, due to variations in the dimensions of each part, H in Figure 3
Even if there are variations in dimensions, the magnetic passbook reading unit 6 is pushed up by the leaf spring 15, so that the tapered connection with the upper cover 4' is reliably performed.

Therefore, there is an advantage that dimensional accuracy in the height direction of the upper cover 4' and the lower cover 2' is not required so much.

Since the upper cover 4' and the magnetic passbook reading unit 6 are tapered into an integral structure, there is no need to align them. Even if ' is moved back and forth, right and left, the position of the magnetic passbook reading unit 6 does not shift.

Cover the top cover 4' with only the passbook insertion slot of the magnetic passbook reading unit 6 open, and then open the magnetic passbook reading unit 6.
Since it is enclosed, it has a sleek appearance, and since there is no gap as mentioned above, there is no fear of dust or foreign matter falling onto the printed boards 18 and 19 shown by dotted lines in FIG.

The present invention has been described above with reference to the embodiments. According to the present invention, a tapered part is provided on the outer periphery of the magnetic passbook reader, and a tapered part is provided on the upper cover at a position opposite to the tapered part of the magnetic passbook reading unit, and the tapered part is fitted with the tapered part of the magnetic passbook reading unit. The structure has a structure in which the magnetic passbook reading unit and the lower cover are attached via a leaf spring. This makes it easy to align the cover.

In addition, the magnetic passbook reading unit is covered with a top cover, so there is no gap like when the magnetic passbook reading unit is exposed, there is no need to worry about dirt or foreign objects getting in, and it has a sleek appearance. be.
