Description

[Detailed Description of the Invention] The present invention is a file search machine, in particular, a reel containing a large number of files arranged side by side in a circular shape is supported in a freely rotatable manner around a center pillar of a base. , supporting a selection device which revolves around the outer periphery of the reel and searches for one of the files from the reel, the device is rotated forward and backward by a motor, and search operation is performed without twisting of the cable connected to the selection device; This article relates to a file search machine that allows you to do this.

This type of file search machine was first proposed by the present application, and in such a file search machine, the selection device is provided with electric parts such as a motor and a search device, and is caused to revolve around the outer periphery of the reel. However, when energizing the electrical components, a cable is used that runs through the center pillar, so when the selection device is rotated by a motor to perform a search operation, the selection device must be rotated in one direction. This will cause a twist in the cable, and in order to resolve this twist, it is necessary to control the selection device so that the direction of rotation is reversed for each search operation. However, the file search machine proposed earlier is configured as follows. That is, it emits light by electrical input, and receives the reflected light of this emitted light and converts it into an electrical signal.
A pair of photosensors is provided in the selection device, and a light shielding plate is provided on the base to block the light emission of the photosensors, and after one search operation by the selection device is completed, the light shielding plate blocks the light emission of the pair of photosensors. Light is blocked in an order corresponding to the rotational direction of the selection device, and the combination of electrical signals of light blocking and non-shading when only one side is blocked is stored in a memory circuit, and the combination of electric signals of light blocking and non-shading is stored in the memory circuit when the selection device starts operating next time. The combination of electrical signals changes the direction of rotation of the motor, causing the selection device to rotate in the opposite direction.

However, since it is necessary to provide a pair of photosensors and a memory circuit, not only is the electric circuit complicated and expensive as a whole, but also when the selection device is orbiting at an intermediate position away from the position of the light shielding plate. If an accident occurs in which the selection device stops at this intermediate position due to the power supply to the electric circuit being cut off, such as in a power outage, the memory circuit will no longer have any memory of the rotation direction of the selection device before it stopped. Therefore, even if the power supply is restarted, there is a problem in that the normal operating state cannot be automatically restored.

The present invention was devised in view of the above problems, and the purpose is to create a simple electrical circuit with a small number of parts, but the power supply to the electrical circuit is cut off like a power outage during search operation of the selection device. hanging down,
The object of the present invention is to provide a file search device that can automatically return to normal operating condition by restarting power supply even if an accident occurs in which the selection device stops at this intermediate position.

That is, in the present invention, a reel containing a large number of files arranged side by side in a circular shape is supported on a base having a center pillar so as to be freely rotatable about the center pillar.

Then, the selection signal from the number key 44 of the keyboard is inputted from the input device 45 to the comparison circuit 50 via the output device 46, and the code code 23 of the desired file 2 is read by the reader 41 of the rotating selection device 4. Then, the read signal is input to the comparison circuit 50, and when the two input signals match, the electric actuator 42 outputs an actuation signal and the search lever 24 is tapped to search for the desired file 2. There is.

Therefore, the switch mechanism A has its first,
As shown in FIG. 2, the second operating members 71 and 72 are arranged at a constant interval in the circumferential direction on the periphery of the circular top plate 12 and at equal distances from the center of the center pillar 11. Both are made of plate material and are parallel to the top plate 12, and the fifth
As shown in FIG.
Cam portions 71a and 72a for operating the actuating member 6 are formed at opposite corners on the radially outer side.

Further, the actuating member 6 of the switch mechanism A and the switches SW ₁ and SW ₂ are mounted inside the upper support member 82 via a mounting member 93 as shown in FIGS. 1 and 5. That is, this mounting member 93 is provided on both sides of the member 82 in the width direction at the part fixed to the support member 82 via a downward step so as to have a switch mounting part, as shown in FIG. The switches SW ₁ and SW ₂ are installed on the bottom of the right and left sides respectively.
. And these switches
SW ₁ and SW ₂ are micro switches equipped with operating levers for opening and closing.The operating levers are opposed to each other, and the free ends of the levers are directed outward in the radial direction of the top plate 12, and The distance from the rotation center of the support member 82 is determined by the first and second operating members 7.
The distance is slightly larger than the distance of 1.72.

The actuating member 6 is formed into a substantially convex shape with a wide part and a narrow part connected by a plate material, with the narrow part facing the center of the top plate 12 and the wide part facing the top plate 12.
2, the end side of the narrow part is pivoted to the mounting part between the switches SW ₁ and SW ₂ in the mounting member 93 via a pin 94, and the end side of the narrow part is supported on the lower and upper surfaces of the wide part, respectively. The first and second operating members 7
1 and 72, and contact the respective cam portions 71a and 72a by rotating as shown by solid line and dotted line arrows.
furthermore, the center pillar 1 of the actuating member 6
The bullet 63 is provided between the mounting member 93 on the first side and the wide part of the operating member 6.

Then, by rotating the support member 82 in the positive direction as shown by the solid line arrow in FIG. When the switch SW ₂ on the left side is turned on, the switch SW ₁ on the right side is turned on and the protrusion 61 passes through to the left without being obstructed by the first operating member 71 The stopping position shown in Fig. 2
It is made so that it can be stopped at _A1 , and it is also made possible to pass through even when starting reverse rotation from this position _A1 , and by rotating the support member 82 in the opposite direction as indicated by the dotted line arrow, By approaching the second operating member 72 just before the end of the rotation, the left downward protrusion 62 comes into contact with the cam member 72a, and the left switch SW ₂ is turned on from the state in which the right switch SW ₁ was turned on. The reverse operation is performed to the on-operation state, and the protrusion 62 passes through to the right without being obstructed by the second operating member 72, so that it can be stopped at the stop position _B1 in FIG. 2, and from this position _B1 . This allows it to pass through even when forward rotation begins.

Further, an electric circuit is constructed as shown in FIG. 4 to control the forward and reverse rotation of the motor 5 by the switches SW ₁ and SW ₂ .

That is, the switches SW ₁ and SW ₂ are connected to the decoder 53.
This is done so that when each switch SW ₁ and SW ₂ is turned on, the output is output from a separate output section. First and second AND circuits 54 and 55 are provided, and one of the two input parts of each circuit 54 and 55 is connected to the output part of the input key 43, and the output part of the decoder 53 is connected to the other one. The output portions of the AND circuits 54 and 55 are connected to the motor 5 via the control circuit 56 and the drive circuit 57.

The control circuit 56 is configured such that the selection device 4
When the first and second operating members 71 and 72 rotate in the opposite direction and change from the state in which the switches SW ₂ and SW ₁ were turned on to the state in which the switches SW ₁ and SW ₂ are turned on, only the stop signal is output. Then, the selection device 4 is stopped at stop positions A ₁ and B ₁ as shown in FIG.

Note that 58 is a stopper of the actuating member 6.

In the above configuration, a large number of files 2 accommodated in the file accommodating portion of the reel 3...
A case where one of the reels is searched from the reel 3 will be explained. The selection device 4 is now in the position shown in FIG.
B ₁ , that is, the end position of reverse rotation, in other words, it is assumed that the motor is stopped at the start end position of forward rotation with switch SW ₂ turned on. In this case, the number key 44 corresponding to the code symbol of the file 2 is selected and operated using the number keys 44 of the keyboard to output a selection signal, and the input key 43 is operated.

By doing so, the second AND circuit 55 is activated to output a forward rotation signal to the motor 5, and the selection device 4 is rotated forward. The selection device 4 thus selects the position
After passing through the position of the second operating member 72 from B ₁ and rotating forward to search for the file 2, the first operating member 71 is rotated as shown on the right side of FIGS.
, the actuating member 6 hits the cam part 71a and operates in reverse, and the switches SW ₂ and SW ₁ are turned off and on, but only a stop signal is output to the motor 5, and the motor 5 remains at position A. will be stopped.

Next, when the number key 44 and the input key 43 are operated to search for the file 2, the first AND circuit 54 is activated and a reverse rotation signal is sent to the motor 5.
After the selection device 4 starts rotating in reverse from position _A1 , passes the position of the first operating member 71, and searches for the file 2, as shown in the drawings on the left side of FIGS. 5a and 5b. When approaching the second operating member 72, the operating member 6 hits the cam portion 72a and reverses operation, and the switches SW ₁ and SW ₂ are turned on and off.
Only a stop signal is output to the motor 5, and the motor 5 is stopped at position _B1 .

As described above, the motor 5 is operated by the switch SW which is kept in the on state in the entire rotation range extending from the operation start positions A ₁ and B ₁ of the selection device 4 to the first and second operation positions 71 and 72 where the stop signal is issued. ₂ , SW ₁
Therefore, even if an accident occurs in which the selection device 4 stops midway due to power supply to the electric circuit being stopped due to a power outage during operation, the switch SW ₂ maintains the on state by restarting the power supply. ，
Power is supplied to the motor 5 via SW ₁ , and the search operation can be completed without any problems.

The above explanation is based on the case where the reel 3 is provided in five stages, but it goes without saying that the reel 3 is not limited to five stages and can be applied to each stage of one or more stages. .

Further, the switch mechanism A has two switches.
Although SW ₁ and SW ₂ are provided separately, only one may be provided, such as a double-pole double-throw type so that forward and reverse rotation can be detected.

Further, the operating member 6 and the switches SW ₁ and SW ₂ are mounted on the top plate 12 of the base 1, and the first and second operating members 71,
72 may be provided on the support member 82 of the selection device 4.

In addition, the operating member 6, switches SW ₁ and SW ₂ , and the first and second operating members 71 and 72 are provided on the top plate 12 and the support member 82, as well as at any corresponding positions on the base 1 and the selection device 4. Good too.

As described above, according to the present invention, even if an accident occurs in which the selection device stops midway due to the power supply to the electric circuit being cut off, such as a power outage, during the search operation of the selection device, regardless of whether the selection device is not powered or powered, Because it is electrically connected to the motor so that it rotates in a predetermined direction via a switch mechanism that is always kept on,
When the power supply is restarted, power is supplied to the motor via the switch that remains on, and the motor automatically rotates in a predetermined direction without any hindrance, allowing the search operation to be completed.

Moreover, since the forward and reverse rotation of the selection device is detected by a switch mechanism, there is no need for complex electrical circuits such as photo sensors and memory circuits, which is also economically advantageous due to fewer breakdowns and easy maintenance. It can be done.
