Description

[Detailed Description of the Invention] The present invention relates to an information item sheet identification device in an information input device in which a plurality of information item sheets are filed in a book-like manner on a ring fitting on a base.

Conventionally, as shown in Japanese Unexamined Patent Publication No. 52-36931, in order to effectively utilize the space on the information item sheet and make the whole compact, a magnetically sensitive body such as a reed switch was installed at the bottom of the ring fitting, and each information item was There is a known device in which each time a sheet is turned over, a magnet fixed to the tip of a movable piece provided opposite each reed switch is pressed to activate the reed switch, thereby identifying the information item sheet that has been turned over. However, the reed switch is housed in a glass case and is exposed, making it extremely susceptible to damage.

In addition, since the reed switch's lead wire serves both for mechanical positioning and electrical connection, the positioning of the reed switch is essentially done by attaching a wiring board for mounting the reed switch. It will be.

Therefore, in order to make effective use of the information item sheet, if an identification means is installed in the section where the sheet is filed, a ring fitting for filing the sheet is attached here, and usually a ring fitting is attached. In order to make the seat movable so that it can be inserted and removed from the ring metal fitting, it has a relatively complicated structure, and if the above-mentioned reed switch is to be placed near this, a wiring board must be additionally attached. However, the structure becomes more complicated, and it becomes extremely difficult to install more reed switches in order to increase the number of sheets.

Furthermore, in the past, reed switches were usually arranged in a direction parallel to the seat, so the area required for installation was large, and for this reason, it was not possible to make the product compact and install a large number of reed switches. .

The present invention eliminates the drawbacks of the conventional method by providing a reed switch inside one side of the ring fitting.

Next, embodiments of the present invention shown in the accompanying drawings will be described in detail.

Reference numeral 1 denotes a base, on which conductors are buried at regular intervals in the vertical and horizontal directions, and tapelets (2, 3.4) are fixed, each having a large number of divisions in the vertical and horizontal directions corresponding to each intersection point. Ring fittings 6 for filing a plurality of information item sheets 5 in book style are arranged vertically between the left and middle tablets 2 and 3 at regular intervals, and the upper and lower parts are ring fittings 6a exclusively for filing.
The middle part is a ring fitting 6b containing a reed switch, and the area around the reed switch is made of at least a non-magnetic material.

As shown in FIG. 3, each information item sheet 5 is provided with a file hole 5a' on the upper and lower projecting pieces 5a of the base 1, which is inserted into the file ring fittings 6a on the upper and lower parts of the base 1, and in the middle part of the base. Identification protrusions 5b are provided at different upper and lower positions corresponding to each information item sheet, and file holes 5b' and attachment holes 5b are inserted into the ring fitting 6b with a reed switch in the middle of the base 1. This is provided.

Reference numeral I designates a detection member in which the bases of two clamping pieces 7a and 7b made of non-magnetic material such as synthetic resin are connected, and the button can be opened and closed by its own elasticity. The magnet 8 is fitted into the recess 7a', and the identification protrusion 5b is inserted into the recess 7a'.
from above and below, and insert the screw 9 into the hole 7 of the upper holding piece 7b.
b' and the attachment hole 5b of the identifying protrusion 5b, and is screwed into the screw hole 7a of the lower clamping piece γa.

In place of the detection member 7, a ring-shaped magnet is used as the identification protrusion 5.
The identification protrusion 5b may be fixed to the outer periphery thereof concentrically with the file hole 5b', or a magnet of an appropriate shape may be fixed to the identification protrusion 5b near the file hole 5b'.

FIG. 4 is an enlarged front view of the main part of the reed switch-containing ring fitting 6b, in which a gap 6C is provided on the negative side, and a well-known reed f-edge 10 is housed inside the gap 6C.

The reed switch 10 has two leads 10a and 10b made of magnetic material arranged one above the other in a case 10C so that their tips are slightly overlapped, and when no magnetic force is applied, both leads 10a are pulled together by their own elasticity.

The tip of the lead 10b is opened and turned OFF when the button is turned OFF when one magnetic pole of the magnet 8 approaches the lead 10a and a magnetic force is acting on the lead 10a, that is, when the magnet 8 is located in section A. The lead 10a is magnetized to the south pole, the lead 10b is magnetized to the north pole by the magnetic induction of the lead 10a, and the lead 10a is magnetized to the north pole.
The tread 10b is closed and turned ON by the mutual attraction of the N and S poles.

As shown in Figure 6, the N and S poles of the magnet 8 are connected to the reed switch 10.
When the middle part of the N pole and the S pole is located approximately at the center of the opposing ends of the leads 10a and 10b, that is, when the middle part of the magnet 8 is located in section B. Lead 10a and lead 10b are connected to S by N and S poles, respectively.
It is magnetized to the pole and N pole, closes, and turns ON.

Both the ring fitting 6b with a reed switch and the ring fitting 6a for files are long on one side and protrude below the mounting plate 11, and have a flange 6a' at the lower end.

A spring 12 is installed between 6b' and the mounting plate 11, and its other side is shortened, and its lower end is fitted and locked in the upper recess 11a of the mounting plate 11.

Therefore, when filing multiple information item sheets 5,
When the required ring fitting 6 is lifted upward against the elasticity of the spring 120, the lower end of the shorter side lifts up from the recess 11a, creating a gap.Insert the information item sheet 5 through the gap, and insert the information item sheet 5 into the file holes 5a', 5. b' into the ring fitting 6, and after inserting a predetermined number of sheets, when the hand is released, the elasticity of the spring 12 pushes the short lower end of the ring fitting 6 into the recess 11.
Fit and lock into a.

13 is a bench touch, and 14 is a fixed information item sheet.

Next, the effect will be explained.

The area where the required information item is displayed is on Tablet 2,
Turn over the information sheet 5 so that it is on the top of page 3.

When each information item sheet 5 is turned to the left, it comes to the left side of the identification protrusion 5b or the ring fitting 6b containing the reed switch, so the magnet 8 attached to the identification protrusion 5b turns on each reed switch 10 corresponding to it. The information item sheet 5 at the top can be identified by detecting which reed switch 10 sequentially arranged in the vertical direction has been turned on.

When the magnets 8 are arranged as shown in FIG. 5, the ON positioning can be done roughly, but when the magnets 8 are arranged as shown in FIG. 6, the ON positioning becomes severe.

According to the present invention, the reed switch is housed in the gap on one side of the ring metal fitting that files the information item sheet, so the reed switch is not damaged by external force, and the reed switch is housed inside the ring metal fitting. Because they are installed, they do not interfere with the installation of ring metal fittings, and because they are arranged perpendicular to the seat, the installation area is small.
This has the effect of making the entire structure more compact.

Note that any other structure may be used for filing the information item sheet on the ring fitting.
