Abstract

PURPOSE:To display and confirm contents for which a doubt arose on a commutation ticket for a commutation ticket user when there is a doubt at entrance or exit by the commutation ticket in a state where a durability of repeating recording is superior, processing time is not prolonged and a problem that mechanical strength is weak is absent. CONSTITUTION:A magnetic recording layer 2c for recording character patterns corresponding to information relating to the entrance or the exit in the form of magnetic latent images is provided separately from the magnetic recording layer 2b for encoding and recording the information relating to the entrance and the exit in the commutation ticket. The character patterns, at the time of entrance, of an entrance date and an entrance station are recorded in the magnetic recording layer 2c in a magnetic latent image state and the character patterns, at the time of exit, of an exit date and an exit station are recorded in the magnetic recording layer 2c in the magnetic latent image state. Then, when the doubt arises, by using a magnetic latent image/visible image conversion member, the character patterns in the magnetic latent image state in the magnetic recording layer 2c on the commutation ticket 2 are visualized.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording medium processing device such as an automatic ticket gate device which performs an entrance process or an exit process using a recording medium such as a commuter pass.

[0002]

2. Description of the Related Art In recent years, for example, in railways, for the purpose of labor saving in ticket gates, it is provided at an entrance or exit of a facility such as a railroad, and when a user who uses the facility enters or exits the facility, When transferring to a facility, an automatic ticket gate device that takes in the commuter passport carried by the user and inspects it, permits the passage of the user if the commuter pass is appropriate, and blocks the passage of the user if it is inappropriate Has been introduced.

This automatic ticket gate apparatus reads magnetic information (for example, an entrance station or an exit station) magnetically recorded on a commuter ticket inserted by a user at the time of entrance, exit or transfer, and the read information. Based on the above, the permission or blocking of the passage of the user is determined. An automatic ticket gate system using such a magnetic commuter pass is widely used.

On the other hand, it has been proposed that a commuter pass is provided with a recording display layer capable of repetitive recording and the state of the recording display layer is changed when entering or exiting (Japanese Patent Laid-Open No. 3-116).
594 and JP-A-3-219432). Further, there is proposed an automatic ticket gate using a commuter pass, which is provided with a storage unit for storing commuter pass information and a means for displaying the remaining number of used tickets (Japanese Patent Laid-Open No. 3-151294).

These are excellent in that they can repeat, record, and erase images, but they are insufficient for repeated use thousands of times like a commuter pass. Further, since thermal recording, which has a slower recording speed than that of magnetic recording, is added, there is a problem that the processing time becomes long.

As a method of excellent durability of repeated recording, a display medium has been proposed in which a space is provided on a magnetic recording layer in a part of a recording medium (magnetic card) and magnetic powder is enclosed in the space. (Japanese Patent Laid-Open No. 50-94906). In this proposal, at least a part of the encoded magnetically recorded information is converted into characters and magnetically recorded, and visualized by a magnetic powder enclosed in a magnetic card so as to be visible from the outside. However, such a magnetic card has a problem that the mechanical strength is weak because a space is provided in the card.

Therefore, the durability of repeated recording is excellent,
When there is a suspicion about entering or exiting a commuter pass without the problem of mechanical strength being weak without increasing the processing time, display the content of the suspicion on the commuter pass to the commuter pass user What can be confirmed is desired.

[0008]

In the past, when entering or exiting a recording medium such as a commuter pass, the durability of repeated recording is excellent, the processing time does not become long, and the mechanical strength is weak. When there is a suspicion, it is desired that the user of the recording medium can display and confirm the contents of the suspicion on the recording medium.

Therefore, according to the present invention, there is no doubt about the entrance or the exit of a recording medium such as a commuter pass, etc., without the problem of excellent durability of repeated recording, long processing time, and low mechanical strength. It is an object of the present invention to provide a recording medium processing device which allows a recording medium user to display and confirm the contents of doubt on the recording medium.

For example, when the display recording unit 2g is on the upper side and the front side is the insertion direction of the commuter pass 2, the writing head 16a records the magnetic latent image of the character pattern.

Further, the CPU 50 determines whether or not the commuter pass 2 can be entered based on the contents read from the reading head 11 or 12, that is, the valid section, the valid period, the last appearance date and time, and the appearance station. .

When it is determined that the entry is possible based on the determination result, the CPU 50 updates the encoded recording content of the magnetic recording layer 2b of the commuter pass 2 using the write head 13 or 14. . That is, the date and time of entry by the automatic ticket gate 1 and the encoding information for the entry station are recorded in the magnetic recording layer 2b of the commuter pass 2.

Read heads 17a, 1 corresponding to the judgment result of the throwing direction of
It is read using any one of 7b, 18a, and 18b, and is supplied to the CPU 50. Then, the CPU 50 checks whether or not the magnetic latent image of the character pattern is correctly recorded on the commuter pass 2.

If the result of this check is correct, the updated recording content of the magnetic recording layer 2b of the commuter pass 2 is read by the read head 19 or 20 and supplied to the CPU 50. Then, the CPU 50 checks whether or not the data recorded on the commuter pass 2 is correct, and if the result of this check is correct, the door part 26 is opened from the discharge port 4 with the door 26 left open, that is, the passage of the inserter is permitted. Eject the commuter pass 2. As a result, the customer passes through the passage and receives the commuter pass 2.

Then, the commuter pass 2 taken in from the receiving port 3 and conveyed on the conveying path 5 reaches the reading heads 11 and 12 after being aligned by an aligning section (not shown). At this time, when the back surface of the commuter pass 2, that is, the magnetic recording layer 2b is on the lower side, the magnetic recording content encoded by the reading head 11 is read and output to the CPU 50. When the back surface of the commuter pass 2, that is, the magnetic recording layer 2b is on the upper side, the magnetic recording content encoded by the reading head 12 is read and output to the CPU 50.

The CPU 50 uses the read head 11 or 12
The insertion direction of the commuter pass 2 is determined based on the contents read from. For example, whether the magnetic recording layer 2b of the commuter pass 2 is on the upper side or the lower side, the display recording section 2g of the commuter pass 2 is on the upper side or the lower side, and the front side or the back side in FIG. Determine if there is. Depending on the result of this determination, the CPU 50
Uses the read head and the write head in the subsequent stage selectively.
For example, when the display recording unit 2g is on the upper side and the front side is the insertion direction of the commuter pass 2, the writing head 16a records the magnetic latent image of the character pattern.

Further, the CPU 50 determines whether or not the commuter pass 2 can be entered based on the contents read from the reading head 11 or 12, that is, the valid section, the valid period, the date and time of the entrance, and the entrance station.

That is, the date and time of participation by the automatic ticket gate 1 and the encoding information for the participating station are recorded in the magnetic recording layer 2b of the commuter pass 2.

Next, the CPU 50 converts the encoding information (character code) for the participation date and time and the participating station and the information indicating the participation into a character pattern using the character generator 64. Next, the CPU 50 causes the write heads 15a, 15 corresponding to the determination result of the insertion direction of the commuter pass 2 described above.

After that, a part of the recorded contents of the magnetic recording layer 2c corresponding to the display recording portion 2g of the commuter pass 2 is part of the commuter pass 2 described above.
Read heads 17a, 1 corresponding to the judgment result of the throwing direction of
It is read using any one of 7b, 18a, and 18b, and is supplied to the CPU 50. Then, the CPU 50 checks whether or not the magnetic latent image of the character pattern is correctly recorded on the commuter pass 2.

If the result of this check is correct, the recorded contents of the magnetic recording layer 2b of the commuter pass 2 are read by the read head 19 or 20 and supplied to the CPU 50. Then, the CPU 50 checks whether or not the data recorded on the commuter pass 2 is correct, and if the result of this check is correct, the door part 26 is opened from the discharge port 4 with the door 26 left open, that is, the passage of the inserter is permitted. Eject the commuter pass 2. As a result, the customer passes through the passage and receives the commuter pass 2.

If there is a doubt in the CPU 50 and entry is not permitted, the CPU 50 provides guidance on a display unit (not shown) and closes the door unit 26.
The commuter pass 2 is discharged from the discharge port 4. At this time, a system administrator may be notified by a buzzer (not shown).

When the character pattern is not correctly recorded on the magnetic recording layer 2c corresponding to the display recording portion 2g of the commuter pass 2, the commuter pass 2 corresponds to the judgment result of the inserting direction of the commuter pass 2. Write heads 15a, 15b, 16
After returning to a and 16b, the magnetic latent image of the character pattern is recorded again.

If the contents recorded on the magnetic recording layer 2b of the commuter pass 2 are incorrect, the commuter pass 2 is replaced by the commuter pass 2 described above.
Write heads 13 and 14 corresponding to the judgment result of the throwing direction of
Then, the process is repeated from the recording of the encoding information.

Next, referring to the flow chart shown in FIG. 13, the process of visualizing (visualizing) the character pattern recorded on the magnetic latent image on the commuter pass when there is a doubt at the time of entry or exit is described. While explaining.

That is, at the time of entry or exit,
If there is a suspicion that entry or exit is denied,
The user who returned the commuter pass 2 goes to the manned aisle side and hands the commuter pass 2 to the system administrator. The system administrator who is handed over the commuter pass 2 in which this suspicion has arisen, is displayed on the magnetic recording layer 2c corresponding to the display recording portion 2g of the commuter pass 2, as shown in FIG. Place and shake gently together.

As a result, the magnetic lines of force act on the magnetic powder 43 of the magnetic latent image-visible image converting member 35 at the location where the polarity is reversed like NN or SS of the magnetic recording layer 2c. By this action, the magnetic powder 43 gathers at this location, and dots of the magnetic powder 43 are formed. The dots of the magnetic powder 43 are formed corresponding to the magnetic latent image on the character pattern, as shown in FIG.

By viewing this from the side of the cover glass 42 of the magnetic latent image-visible image converting member 35, the display recording portion 2g is obtained.
It is possible to ask the user of the commuter pass 2 to confirm the presence or absence of a magnetic latent image on the magnetic recording layer 2c of FIG.

That is, at the time of participation, this display recording section 2g
If the character pattern corresponding to the entrance information is not visualized, or if the character pattern of the entrance or exit information such as another date is visualized, an illegal boarding is confirmed.

When the character pattern corresponding to the previous entry information is not visualized in the display recording unit 2g at the time of entry, or when the character pattern of the entry information such as another date is visualized. , Illegal boarding is confirmed.

As described above, in the automatic ticket gate system using the commuter pass according to the present invention, the commuter pass is put into a device such as a magnetic medium reader, and magnetic information is read in the device.
Unlike displaying it on the display and presenting it to the user,
It is possible to convince the user that the information written on the commuter pass and the visualized image have a one-to-one relationship.

As a result, at the time of entry or exit, if a doubt arises and entry or exit is not permitted,
Unauthorized boarding corresponding to the suspicion can be confirmed on the commuter pass presented by the user.

Further, the durability of the repeated display of the character image in the display recording section 2g is equivalent to the durability of the magnetic storage layer, and the durability is sufficient even in a commuter pass application requiring a high repeated display durability. Guaranteed.

Further, since the recording on the magnetic recording layer 2c for the display recording portion 2g can be performed at the same speed as the recording on the conventional magnetic recording layer 2b, the processing speed is remarkably higher than that of the system for reversible recording by heat. Can be improved.

Further, unlike the conventional example using magnetic powder, there is no space portion in the commuter pass which impairs the mechanical strength, so that the commuter pass with excellent mechanical strength can be provided, and therefore the reliability of the system is improved. Can be achieved.

Further, since the encoded information recorded on the magnetic recording layer 2b is confirmed after the magnetic latent image is recorded on the magnetic recording layer 2c, the magnetic recording layer 2c is confirmed.
Even if the recording content of the magnetic recording layer 2b is changed (destroyed) by recording the magnetic latent image on the magnetic recording layer 2b, the recording on the magnetic recording layer 2b can be performed again, and the recording on the magnetic recording layer 2b is surely performed. It can be carried out.

In the above embodiment, the case where the display / recording section of the commuter pass is provided on the lower left side as shown in FIG. 5 is not limited to these, but it is provided at the center of the commuter pass. You may do it. In this case, two write heads and two read heads for writing information on the magnetic recording layer corresponding to the display recording section may be provided above and below, respectively.

Further, the recording confirmation of the magnetic latent image of the character pattern on the magnetic recording layer corresponding to the display recording section is confirmed by the presence or absence of the magnetic latent image of the character pattern, but the present invention is not limited to this. By reading all the character patterns of the image and checking by matching with the character pattern when writing, you can confirm, or read all the character patterns of the magnetic latent image and convert the read character pattern into a character code, The confirmation may be performed by checking the match with the character code encoded and recorded.

Further, when the magnetic latent image corresponding to the character pattern is confirmed and the encoding information is confirmed, the corresponding process is performed again, but the present invention is not limited to this, and the process is terminated as a jam state, Alternatively, it may be refilled.
