Description

[Detailed explanation of the idea] The present invention relates to an information card search device.

Various types of devices have been proposed for searching and pulling out information cards such as aperture cards, punch cards, microfiche, etc. according to codes.

However, most of these methods utilize the card's own weight, and have drawbacks such as complicated devices and/or unreliable withdrawal.

In addition, many of these methods were time-consuming in terms of operability.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an information card retrieval device which eliminates the above-mentioned conventional drawbacks, has a simple configuration, and can reliably perform retrieval by using magnets.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

In FIG. 1, a card 4 that stores a large amount of information has a permeable search magnetic section 1 on one piece thereof, and code sections 2, 2' each consisting of 5 bits in this example on both sides of the magnetic section. Notches 3 are provided in two of the five bits according to the code number.

A large number of cards 4 are housed side by side in a case 6 with one side open, and in this case, the edges of the cards having the code portions 2, 2' are aligned and exposed toward the outer periphery for easy retrieval. It is accommodated.

Furthermore, the card 4 has ears 5 formed at both ends thereof on the side of the cord portion.

A search device 7 installed in a reading device such as a microreader is comprised of a card case accommodating section 8 and a search section 9, as shown in FIG.

A tray 10 supporting the card case 6 is guided by a guide rod 11 in the card case accommodating section 8 so as to be movable up and down.

The tray 10 is moved up and down manually or by motor drive.

The search section 9 has a select arm, which will be described later, located in a sorting zone located at a position facing the moving surface of the magnetic section 1 of the card 4 in the movement path of the storage section 8, that is, approximately at the center of the search section in FIG. A retrieval permanent magnet 12 is fixed at a position close to and substantially parallel to the OFF position of the retrieval magnet 16.

A predetermined number of selectors 13, for example, five selectors 13, are arranged on both sides (may be only one side) with the search magnet 12 in between.

The selector 13 is swingably supported by a rod 14 fixed to the frame of the apparatus, and is held at a predetermined interval by a partition member 15.

The interval between the selectors 13 is determined according to the interval between the bits of the card 1.

The selector 13 has a select arm 16 and a sensing arm 17 projecting from the support provided by the rod 14.

Note that the length of this select arm 16 corresponds to the sorting zone.

The sensing arm senses a command from the device indicating the code of the card to be removed, and in response to the command, select arm 16 is activated.
Set to ON or OFF position.

In the OFF position, the select arm 16 is in an oblique state, as shown in FIG. However, in the ON position, it is almost parallel to the edge of the card on the notch side, allowing the card to be attracted by the magnet for cards with notch 3 at the position corresponding to the select bar, and Block any cards you don't want, and choose a card from there.

Separators 1 are provided on both sides of the search unit 9 to separate predetermined cards selected by the search from other cards.
8 is fixed, and the separator 18 has a take-out path guide surface 19 and a passage guide path 20.

The separator 18 cooperates with the select arm 16 of the selector 13, and the ears of the card allowed to be attracted to the magnet 12 by the select arm 16 are moved along the guide surface 19 to remove the card that is prevented from being attracted to the magnet 12. Ear 5 is the guideway 20
The position of the separator 18 is determined so that it passes through.

Rotating belts 21 are disposed on both sides of the search section 9 so that the cards 4 are lowered in synchronization with the movement of the card case when the card case is lowered.

The belt 21 is wound around the rollers 22 and 23, and the roller 24 moves the card parallel to the moving direction of the card case until the card reaches the vicinity of the magnet 12. It is turned so as to be guided parallel to the plane, that is, approximately parallel to the OFF position of the select arm 16.

The roller 22 is rotatably supported by the search device casing,
The roller 23 is supported by the search device casing and driven by a drive device (not shown).

The selected card 4 is attached to the magnet 12 on the same axis as the roller 23.
It is convenient to provide an oyster dropping roller 23a for separating the oysters from the magnetic force.

The oyster dropping roller 23a can also be formed integrally with the roller 23.

It is preferable to have teeth on the circumferential surface of the oyster-dropping roller 23a in order to move the card 4 against the attraction force of the magnet 12 (FIG. 3).

In FIGS. 4 and 5, dials 25 and 26 are provided outside the search unit casing.

The dial 25 is fixed to a shaft 32 rotatably supported by the search section casing, and the dial 26 is fixed to a shaft 34 rotatably supported by the search section casing.

The dial 25 is for setting the tens digit, and the dial 26 is for setting the digit for the 1st digit.On the dial surface, symbols from 0 to 9 are written respectively, and the numbers are indicated by the arrow 24' written on the search part casing. By matching, the code number is specified.

FIG. 4 shows a state in which code number 32 is set.

A camshaft 30 is rotatably fitted loosely into the shaft 32, and a camshaft 31 is inserted and fixed with a set screw or the like to prevent relative rotation.

The cam shaft 30 has a cam 27 that indicates a code number in the 1's digit.
is fixed by a key or the like, and a cam 28 for indicating a code number in the tens digit is fixed to the shaft 31 by a key or the like.

In FIG. 5, both the camshaft 30 in the 32nd digit and the camshaft 31 in the 10th digit are mounted on the same shaft, so that the rotation of the dial 26 in the 1s digit is transmitted to the camshaft 30 on a one-to-one basis. A gear pair 33, 35 that meshes with each other is provided.

The gear 35 is fixed to the shaft 34, and the gear 33 is fixed to the camshaft 30.

Depending on the size of the cam, the shape and size of the selector 13, etc., it is also possible to mount the 1's cam 27 and the 10's cam 28 on separate shafts 34 and 32, respectively.

The cams 27 and 28 are formed by combining a number of single cams corresponding to the number of bits, that is, five cams in the figure, in parallel.

Of course, 5 cams are arranged in one cam as if 5 cams were arranged
It is also possible to form rows of cam surfaces.

The surfaces of the cams 27 and 28 are formed with unevenness, and the sensing arm 17 of the selector 13 is pressed against the cam surface by a spring 29.

In the example shown in the figure, the selector 13 in which the sensing arm 17 is in contact with the convex portion of the cams 27 and 28 is in the ON position.
Selector 13 with sensing arm 17 in contact with the recess of
is set to the OFF position.

The figure shows an example in which a two-digit code number can be specified using two sets of select bars, but if necessary, one set or two sets of select bars, etc., and their corresponding By adding a cam and a dial, a 3-digit or 4-digit code number can be specified.

The umbrella cams 27 and 28 each have a convex portion at each setting position where the circumferential surface is divided into 10 setting positions, depending on the state of the select bar predetermined for the code number. Or a recess is formed.

For example, when forming a code by providing notches in two of the five bits, two of the five selectors 13 must be set to the ON position.

Therefore, 5 single cams of cams 27 and 28 or cams 27
．． Convex portions for two of the 28 five rows of cam surfaces must be provided for each of the ten set positions.

Depending on the shape of the select bar, on the other hand, place two pieces in the recessed part 3.
It is also possible to make each piece convex.

Table 1 shows an example of setting the position of the convex portion on the cam surface.

Convex portions are provided at the circled positions in the table, and recessed portions are provided at other positions.

Conversely, a concave portion may be provided at the ◯ position and a convex portion may be provided at another position.

Once the relationship between the code number and the position of the convex portion of the cam is determined as described above, the shape of each individual cam or cam row is determined, as can be seen from the table above.

For example, considering the single cam 1, one circumferential surface is formed by arranging the convex portions and concave portions in the order of convexity, convexity, convexity, convexity, convexity, convexity, one concave, one concave, one convexity, one concave.

Naturally, if the relationship between the code number and the code notch is changed, the cam shape mentioned above will also change.

By using such a cam, when the dials 25° and 26 are set to a predetermined number, the positions of the protrusions and recesses of the cam are automatically determined, and therefore the ON and OFF positions of the select bar are determined automatically.
Position selection settings are made.

According to the example in Table 1, the state of the cams in contact with the sensing arm 17 of the select bar when the dial is set to the dial position shown in FIG. 4 is as follows: In FIG. ......5, the position where the sensing arm 17 contacts is convex - concave one concave one concave one convex, concave -
One convex, one concave, one convex, one concave.

A click device is provided so that when a code number is set by rotating the dial 25, 26, a change in the position of the number can be detected and the dial and cam are held at the set position.

That is, click cams 37.3 are attached to cam shafts 30.31, respectively.
B is fixed and the click pins 39, 40 cooperating with the recesses of the click cam are slidably held in the guide holes of the click guide bar 41.

Click pins 39 and 40 are click guide bars 41 respectively.
It is pressed against the click cam 37.38 by a click leaf spring 42.43 fixed to the click cam 37.38.

The click cam is provided with ten recesses 36 on its circumferential surface corresponding to the selected positions of the cams 27, 28, that is, the scales of the dial 25°26.

The click pin is pressed into this recess, so when you turn the dial, you will feel resistance when the scale changes, and as you pass the change mark, the resistance will decrease.Moreover, the engagement of the click pin in the recess will ensure that the cam is in the correct position. Since the code is set, code selection by dialing can be done reliably and easily.

Due to the engagement of the click pin with the recess of the click cam, the cams 27, 28 are held in such a way that even some mechanical vibrations do not cause a change in position.

The selected card that is attracted by the search magnet 12 and sent along the guide surface 19 of the separator 18 without being stopped by the select bar 13 is separated from the magnetic force of the magnet 12 by the oyster drop roller 23a and placed on the guide plate 44. will be guided to.

A take-out device is attached to the guide plate 44.

The take-out device includes a take-out/insertion lever 45 that is rotatably supported in the direction of pulling out the card at positions corresponding to the positions of the card ears on both sides of the guide plate 44, and a feed-out position of the take-out/insertion lever 45 shown by a chain line. The card feeding roller device is comprised of a card feeding roller driven by a motor and an idler rotatably supported at one end of a lever 49 which is swingably supported on a fulcrum 48. The other end of the lever 49 is connected to the solenoid 5.
It is pivoted to No. 1 Rondo.

The idle roller 50 is oscillated by the operation of the solenoid 51 between a standby position (indicated by a solid line) and a feeding position (indicated by a chain line) in cooperation with the card feeding roller.

The ejecting/inserting lever 45 is positioned in the retrieval section so that the tip of the lever 45 moves the card by rotating while pushing against the lug 5 of the card.

The operation of the search device will be explained.

First, the code dials 25 and 26 are set to a desired coat number, for example 32 in FIG.

The cams 27, 28 are set by setting the dials 25, 26, and a predetermined selector 13 is set to the ON position and other selectors 13 are set to the OFF position.

It is set on the tray 10 of the card case 6 and moved manually or by a drive device such as a motor in synchronization with the downward movement of the tray 10.

Synchronous movement of tray 10 and belt 21 can be obtained using conventional mechanisms or using electrical devices.

When the tray 10 is lowered, the magnetic part 1 of the card is connected to the search magnet 12.
is attracted to.

The select bar in the ON position and the cord notch 3 are separated from the magnet 12 by the select arm 16 of the card select bar that does not match, and are guided to the guide path 20 of the separator 18 according to the downward movement, and the card is pulled out from the card case. It is kept in a contained state without any trouble.

On the other hand, when the select arm 16 in the ON position matches the notch of the card, the card is lowered under the attraction force of the magnet 12 and moved along the guide surface 19 of the separator 18.

The downward movement of the card is not synchronized with the downward movement of the case 6 due to the attraction force of the magnet, and an unreasonable force is generated on the card. This is avoided by the card 4 being rubbed and subjected to the conveyance action.

The selected card is moved to the magnet 12 by the oyster drop roller 23a.
The tray 10 is controlled by a limit device or the like so that the tray 10 is stopped when it is separated from the suction force and reaches the top of the guide plate 44.

If there is no card to be selected, the tray 10 is moved to the lowest position.

The selected card is placed on the guide plate 44 and tray 1
0 stops, the ejecting/inserting lever 45 is moved.

When the card reaches the guide plate 44, the card is guided so that the card's ear 5 is located in front of the tip of the lever 45, so when the lever 45 rotates, the card's ear 5 is pressed by the lever 45, and the card is It is pulled forward from the case 6.

At the pivot end, the lever 45 hangs below the ears of the card, so it stops away from the card.

When the lever 45 stops, the solenoid 51 is actuated to push up the idle roller 50.

At this time, the card is caught between the card feed roller 47 and the idle roller 50, and by the rotation of the feed roller 47, the card is further pulled out from the case 6 and handed over to a card catcher (not shown) at a predetermined position.

When the card reaches a predetermined position, the solenoid 51 is deactivated, the idle roller 50 is lowered, and card feeding is stopped.

The card is thus read by the reading device.

According to the present invention, information cards can be searched and retrieved reliably with a simple structure and therefore compact, and the operability is improved.
