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, a reed switch is disposed below a ring fitting, and a magnet fixed to the tip of a correspondingly provided movable piece is opposed to the reed switch, and each information item is Fix the cam to the edge of the seat,
There is a known device in which a cam pushes down a magnet when an information item sheet is turned over and activates a reed switch to identify the information item sheet. The cam or magnet was fixed to the seat, or placed in a holder and fixed with screws, but it took a lot of effort to fix the cam or magnet to the seat, and the cam or magnet protruded from the seat when the seat was stored or transported. Packing is troublesome and bulky, requiring a lot of space, and when the seat is worn or worn out due to bent touch, it is troublesome to remove the magnet when replacing the seat, and it cannot be removed. Since the magnet or cam must be discarded, there is a disadvantage that it is economically wasteful.

The present invention eliminates the drawbacks of the conventional method by allowing a magnet to be easily and detachably attached near the file hole of a sheet without using adhesives, screws, or holders.

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

1 is a base on which conductors are embedded at regular intervals in the vertical and horizontal directions, and tapelets 1-2 and 3.4 are fixed thereon, each having a large number of divisions in the vertical and horizontal directions corresponding to each intersection point. A ring fitting 6 for filing a plurality of information item sheets 5 in book style is arranged at regular intervals in the vertical direction between the tablets 2 and 3 on the left side, and a base on the left side of the ring fitting 6. 1
A plurality of reed switches I are arranged on the upper surface in correspondence with a plurality of ring fittings 6.

As shown in FIG. 3, each information item sheet 5 is provided with file holes 5a' in the file-dedicated projecting pieces 5a on the upper and lower parts of the base, and in the middle part of the base, file holes 5a' are provided at different positions on the upper and lower sides corresponding to each information item sheet. An identification protrusion 5b is provided, and a file hole 5b' is provided.

Reference numeral 8 denotes a magnet having a cross-section of [shaped] and is provided with a hole 8a.The magnet 8 is inserted into the identification protrusion 5b, and the magnet 8 is inserted into the ring fitting 6 with the holes 8a and 5b' aligned.

Even when the ring fitting 6 falls down, one side becomes longer and protrudes below the mounting plate 9, and a spring 10 is installed between the collar 6a at the lower end and the mounting plate 9. The other side is shortened, and its lower end is fitted and locked into a recess 9a on the upper surface of the mounting plate 9.

When filing, attach the necessary ring fitting 6 to the spring 10.
Lift the short end upward against the elasticity of the recess 9.
a, insert the file special protrusion 5a, the magnet 8, and the identification protrusion 5b through the gap, and insert the file hole 5a', the magnet hole 8a, and the file hole 5b' into the ring fitting 6, aligning them. After inserting a predetermined number of sheets, when the hand is released, the short lower end of the ring fitting 6 is pushed into the recess 9a by the elasticity of the spring 10.
is locked.

FIG. 4 shows another embodiment of the magnet, which has an L-shaped cross section and has a hole 8a' formed therein.

11 is a bench touch, and 12 is a fixed information item sheet.

Does reed switch l have two leads made of magnetic material inside case 7C? a and 7b are arranged above and below so that their tips are slightly overlapped, and when no magnetic force is applied, they are held together by their own elasticity.
Do? The tips of a and 7b are open and turned OFF, and when one of the magnetic poles of the magnet 8 or 8' approaches one lead 7a and a magnetic force is acting, as shown in FIG. When 8' is located, the lead 7a is magnetized to the south pole, and the lead 1b is magnetized to the north pole by the magnetic induction of the lead 7a, and the leads 7a and 7b are attracted to different north and south poles. It closes due to action and turns ON.

As shown in FIG. 6, the N and S poles of the magnet 8 move parallel to the reed switch 7, and the intermediate part between the N and S poles is connected to the reed switch 7a.
When the lead 7a and the lead 7b are located approximately at the center of the opposite end thereof, that is, when the middle part of the magnet 8 or 8' is located in the section B, the lead 7a and the lead 7b have an N pole and an S pole, respectively. It is magnetized to the S and N poles and turns ON.

When the magnet 8 or 8' is arranged as shown in Fig. 5, O
The N positioning may be rough, but when the arrangement is as shown in FIG. 6, the ON positioning becomes severe.

Next, the effect will be explained.

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

When each information item sheet 5 is turned over to the left, an identification protrusion 5b is displayed.
The magnet 8 or pin inserted into the magnet 8 is superposed on the corresponding IJ-Tosuinochia, the reed switch 7 is turned on, and the reed switch sequentially arranged in the vertical direction is turned on.
The information item sheet 5 at the top can be identified by detecting whether the number N has been reached.

According to the present invention, it is only necessary to make a hole in a magnet with a [shaped or L-shaped cross section, insert it into the identification protrusion of the information item sheet, align the wire hole with the file hole, and insert it into the ring metal fitting. It is extremely easy to install, and when the information item sheet becomes worn out or worn out due to bending, it is easy to replace.
When the information item sheet is removed from the ring fitting, the magnets are also removed separately, which has the effect that the magnets can be reused.

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