Description

[Detailed Description of the Invention] (Field of the Invention) The present invention relates to a token used for issuing control of a parking lot such as a bank, and in particular, a magnetic sensor attached to a collecting means is used to detect and discriminate the token. The present invention relates to a token that causes a drive mechanism of an automatic opening / closing gate to perform an opening operation when judged.

(Outline of the Invention) The present invention makes it possible to inexpensively manufacture the above token while making it difficult to forge.

(Prior Art and Problems Thereof) This type of token is used, for example, in a parking lot such as a bank for customer service while simplifying its management. That is, while the storage side can be managed by security guards or can only freely enter, the output side has an automatic opening / closing gate and token collection means for collecting tokens, and customers using banks etc. The customer can hand over the token at the time of leaving and the customer can put the token into the token collecting means to automatically open the gate and leave. This prevents anyone other than the customer from illegally using the parking lot, and simplifies management on the delivery side by unmanning.

The following tokens have been generally known as tokens.

(I) First Conventional Example A metal member having a circular shape, that is, a so-called metal. This metal is put into a collecting means, and the shape and weight of the metal are discriminated by a metal selector attached to the collecting means side. I try to open the gate when it is right.

(Ii) Second Conventional Example A magnetic card in which a specific code is stored, and a card reader is projected on the collecting means side as a sensor senses that a vehicle is approaching, and the magnetic card is inserted into the card reader. By inserting, the code is read and it is determined whether it is appropriate.

(Iii) Third Conventional Example An oscillator that oscillates an inherent frequency signal and a power source for the oscillator are built in a resin case or the like. The resin case is put into a collection means and oscillated from the oscillator. The frequency signal is detected by a dispenser attached to the collecting means side to determine whether or not the frequency signal is a predetermined one.

However, each of the conventional examples having such a configuration has the following drawbacks.

Disadvantages of the first conventional example Although the manufacturing cost is low and the usability is good, a third party can easily forge and it is difficult to prevent illegal use.

Disadvantages of the second conventional example Although the manufacturing cost is relatively low and there is an advantage that it is possible to prevent forgery, the customer has to reach out from the window and insert the magnetic card into the card reader, which is not convenient for the customer. Is uncomfortable and difficult to put into practical use.

Disadvantages of the third conventional example Although forgery can be prevented and the convenience of use is good, the manufacturing cost is extremely high because of the built-in oscillator and power supply. Similar to the third conventional example, in order to make the power source unnecessary, a resonance circuit composed of the coin L and the capacitor C is built in a resin case or the like, and the resonance frequency is detected on the collecting means side. It is also considered to determine whether or not it is appropriate, but the manufacturing cost is not so low.

(Purpose of the Invention) The present invention has been made in view of the above circumstances, and an object thereof is to make it easy to use and inexpensive to manufacture while preventing forgery. .

(Structure and Effect of the Invention) In order to achieve such an object, the present invention causes a magnetic sensor attached to a collecting means to detect and discriminate, and when it is determined to be appropriate, opens a drive mechanism of an automatic opening / closing gate. In the token for performing the above, a rod-shaped and opaque covering member is divided into two along the longitudinal direction thereof, and a plurality of pairs of mounting recesses are formed along the longitudinal direction on the respective divided surfaces of the divided bodies, A metal member is attached to an appropriate one of the attachment recesses so that the covering member is integrally formed.

In other words, even if the shape of the metal member is disk-shaped, spherical, or perforated, even if the shape is simple, the metal member is covered with the opaque covering member. It cannot be known from the outside and can be easily forged.

Moreover, the metal member and the covering member made of a synthetic resin case or the like can be configured, and as described above, the metal member having a simple shape can be selected, and the manufacturing cost thereof can be reduced. became.

Further, since the covering member is formed in a rod shape, the token can be easily put into the collecting means by throwing it through the window of the automobile into the input port of the collecting means, and the usability can be improved.

In addition, since the covering member is divided into two parts, and the metal member is attached to an appropriate one of a plurality of pairs of mounting recesses formed along the longitudinal direction on the inner surface of the split body, the mounting recess is appropriately selected. Then, by mounting the metal member, it is possible to easily obtain a token that produces a different detection pattern with the covering member being common.

(Description of Embodiments) Hereinafter, the present invention will be described in detail based on embodiments illustrated in the drawings. FIG. 1 is a partially cutaway exploded vertical sectional view of a token A according to an embodiment of the present invention, and FIG. 2 is an overall perspective view. In these figures, 1 is a flat washer as a metal member (for example, thickness is 1 to 2 mm and diameter is 10 to 15 mm), 2 is
It is a case made of ABS resin as a covering member.

The case 2 is formed by bonding semi-cylindrical bodies 2a having the same shape. Grooves (mounting recesses) 3 are formed in the semi-cylindrical bodies 2a, 2a at predetermined intervals in the longitudinal direction,
The flat washers 1 are fitted in the grooves 3.

Next, the usage pattern of the token A thus manufactured will be described.

That is, as shown in FIG. 3, in a parking lot P such as a bank, an entrance I and an exit O are exclusively provided, and the exit O is provided with an automatic opening / closing gate 4. The gate 4 is configured to be opened and closed by a drive mechanism 5 such as an electric motor.

At the exit port O, a token collector 6 as a collecting means is installed in front of the gate 4, and the control device of the token collector 6 and the drive mechanism 5 are linked to each other to form the token collector 6
When a proper token A given by a manager of a parking lot such as a bank is put in, the drive mechanism 5 is automatically operated,
It is configured to open the gate 4.

As shown in the overall longitudinal sectional view of FIG. 4 and the front view of FIG. 5, the token receiver 6 is formed by forming a large-area input port 9 in the upper part of the casing 8. A hopper portion 10 is formed at the back of the charging port 9, and
A downflow chute portion 11 is formed at the lowermost end of the hopper portion 10 so as to guide and flow down the token A in a predetermined posture. The magnetic sensor 1 is provided at an intermediate position of the downflow chute 11.

Reference numeral 14 is a return port for returning the token A when it is determined to be improper, 15 is a storage box for collecting and accommodating the token A determined to be proper, and 16 is in accordance with the discrimination result of the discrimination device 13. A flapper for selectively transferring the token A to the return port 14 or the storage box 15.

Reference numeral 17 denotes a door handle for taking out the token A collected in the storage box 15 and inspecting the inside.

As shown in FIG. 6, the magnetic sensor 12 has two magnetoresistive sensors 12a, 12a connected in series, and both magnetoresistive sensors 1
The sensor output accompanying the passage of the token A is taken out from the connection point of 2a and 12a. That is, when the flat washer 1 which is a magnetic material approaches the sensor detection surface, the magnetic flux density of the magnetoresistive sensors 12a, 12a changes, which causes a counter electromotive force to be provided and causes a voltage change. It is taken out as a sensor output. As shown in FIG. 7 (a), this sensor output is output to a rising output and a falling output for each flat washer 1, and is input to the amplification detecting unit 18 constituting the control device to As shown in FIG. 7B, a pulse signal that rises in response to the rising output and falls in response to the falling output is output. After that, it is input to the discriminating device 13 (CPU), and in the discriminating device 13, the time from the first rising edge of the pulse signal to the subsequent rising edge of each pulse signal.
When t ₀ , t ₁ , t ₂ , t ₃ is measured, the time is compared with a preset time, and when they match, a token A is determined to be proper and an open signal is output to the control device 7. Then, the drive mechanism 5 is caused to perform an opening operation, and the flapper 16 is operated to collect the token A in the storage box 15. On the contrary, when they do not match, neither the drive mechanism 5 nor the flapper 16 is operated, Token A return port 14

Next, the determination operation by the determination device 18 will be described in detail with reference to the flowchart of FIG.

First, the flat washers 1, ... Are detected and input (F1), and their detection times are measured (F2).

Next, it is determined whether or not the detection is completed (F3), and if the detection is completed, then it is determined whether or not the number of the flat washers 1 matches the set number (F4). Furthermore, it is determined whether or not the detection time of the flat washer 1 matches the minimum time and the maximum time set respectively for the minimum time and the maximum time (F5).

Then, the pulse signal is patterned based on the detection time of the flat washer 1 (F6), and it is determined whether the pattern matches the set pattern (F7). To activate the flapper 16 (F8), collect the token A in the storage box 15, and output an opening signal to the driving mechanism 5 to perform the opening operation (F9), and open the gate 4. It is automatically issued. Once this gate 4 is opened,
The open state is maintained for a set time, and after the set time elapses, the open state is automatically closed.

When it is determined that they do not match in each of the steps F4, F5, and F7, the process ends as an error, neither the drive mechanism 5 nor the flapper 16 is operated, and the token A is sent to the return port.

The detected number of flat washers 1 accompanying the detection in step F1, the detection time in step F2, and the data patterned in step F6 are
