DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings.
[0016]
FIG. 1 is a cross-sectional view showing a schematic configuration of an automatic ticket gate according to the present invention.
[0017]
As shown in FIG. 1, the automatic ticket gate apparatus includes a main body 1 that performs ticket gate processing (entrance work and entry work). The main body 1 has an insertion port 3 into which the ticket medium P is inserted when entering the station or entering the station, and an outlet through which the ticket medium P received at the insertion port 3 is discharged. 4 are provided. In the vicinity of the insertion slot 3, a shutter (not shown) for preventing the insertion of a commuter pass or the like is provided. On the side surface of the main body 1 of the automatic ticket gate, there is provided a door portion 6 for blocking the passer of the ticket medium P by closing.
[0018]
Between the slot 3 and the outlet 4 is formed a main transport path 11 for transporting the ticket medium received by the slot 3 to the outlet 4 (arrow a direction). On the transport path of the main transport path 11, along the insertion port 3 to the discharge port 4, an alignment unit (not shown), magnetic information reading units (reading heads) 14 and 15, and magnetic information recording units (writing heads) 16 and 17. , And magnetic information reading units (reading heads) 18 and 19, a hooking unit 21, a holding unit 22, and a print recording unit (thermal head) 30 are provided in this order.
[0019]
The read heads 14 and 15 read encoded magnetic information recorded on the magnetic recording layer on the back surface of the ticket medium. The read head 14 reads magnetic information when the magnetic recording layer is conveyed on the lower side, and the read head 15 reads magnetic information when the magnetic recording layer is conveyed on the upper side.
[0020]
The write heads 16 and 17 record predetermined encoded magnetic information on the magnetic recording layer on the back surface of the ticket medium. The write head 16 records predetermined magnetic information when the magnetic recording layer is conveyed on the lower side, and the write head 17 determines predetermined magnetic information when the magnetic recording layer is conveyed on the upper side. Is to be recorded.
[0021]
The read heads 18 and 19 read the encoded magnetic information recorded by the write heads 16 and 17. The read head 18 reads magnetic information when the magnetic recording layer is conveyed on the lower side, and the read head 19 reads magnetic information when the magnetic recording layer is conveyed on the upper side.
[0022]
A support member (rotating roller) 20 is provided along the transport path 11 on the opposite side of the transport path 11 from the read heads 14 and 15, the write heads 16 and 17, and the read heads 18 and 19.
[0023]
The ridge portion 21 is used to open a punch hole (perforation) as a ridge in the ordinary ticket or the like conveyed by the conveyance path 11. The holding unit 22 holds the boarding ticket or the like when the punching hole (perforation) is opened in the boarding ticket or the like by the hooking unit 21. The print recording unit 30 prints and records predetermined information on the transported ticket medium.
[0024]
A distribution unit 23 is provided between the print recording unit 30 and the discharge port 4. The distribution unit 23 distributes the ticket medium in the direction of the discharge port 4 when the received ticket medium is to be discharged, and collects the ticket medium when the received ticket medium is to be collected. Distribution is made in the direction of the collection unit 25. The tickets distributed to the collection unit 25 side by the distribution unit 23 are collected by the collection unit 25 via the shooter 24.
[0025]
Furthermore, a detector (not shown) for detecting the passage of the ticket medium being conveyed is provided on the main conveyance path 11.
[0026]
Next, the control block of the automatic ticket gate described above will be described with reference to FIG.
[0027]
The automatic ticket gate is entirely controlled by the main CPU 40. The main CPU 40 includes a ROM 41 that stores a control program for the main CPU 40, a RAM 42 that stores information read from a ticket medium and a buffer for a control program, and an entrance station (from the automatic ticket gate). A fare memory 43 storing fare information corresponding to the installed station), a read circuit 44 for controlling the read heads 14 and 15, a write circuit 45 for controlling the write heads 16 and 17, and a read head 18 , 19 is connected.
[0028]
Further, the main CPU 40 detects the transport state of the ticket medium based on the output of the distribution control circuit 47 for controlling the distribution gate 23, the control circuit 31 for controlling the print recording unit 30, and the detector 48 for detecting passage. A detection circuit 49; a conveyance control circuit 51 that controls a conveyance motor 50 that conveys the ticket medium along the conveyance path 11; a door control circuit 54 that controls a door opening / closing mechanism 53 that drives the door 6; An input control circuit 56 that controls the flange 21 is connected.
[0029]
Next, the ticket gate processing (entry service and entry job) by the automatic ticket gate described above will be briefly described.
[0030]
When the ticket medium is inserted into the insertion slot 3, the inserted ticket medium is transported on the main transport path 11 in the direction of arrow a. Then, the ticket medium is aligned by a positioning unit (not shown) and then reaches the reading heads 14 and 15. At this time, if the back surface of the ticket medium, that is, the magnetic recording surface is the lower surface, the magnetic recording content is read by the reading head 14, and the read information is stored in the RAM 42. When the back surface of the ticket medium, that is, the magnetic recording surface is the upper surface, the magnetic recording content is read by the reading head 15 and stored in the RAM 42. The main CPU 40 determines the validity of the ticket medium by analyzing the stored contents stored in the RAM 42.
[0031]
At this time, if it is determined that the inserted ticket medium is not valid, the main CPU 40 displays a guidance to that effect on a display unit (not shown). In this case, the main CPU 40 closes the gate 6, transports the inserted ticket medium on the main transport path 11, and discharges it from the slot 3. When it is determined that the inserted ticket medium is valid, the main CPU 40 keeps the gate 6 open, that is, allows the passer to pass through, and discharges or collects the ticket medium from the outlet 4. To do.
[0032]
Subsequently, punch hole position detection will be described. Before that, the ticket information magnetically recorded on the ticket ticket medium will be described first. FIG. 4 is a diagram showing an information recording medium on which ticket information is magnetically recorded (encoded) and punched. As shown in FIG. 4, the punch holes are opened along the recording direction of the ticket information. The ticket medium is transported along the direction in which the ticket information is recorded.
[0033]
The details of the ticket information magnetically recorded on the ticket medium have a frame bit structure as shown in FIG. For example, the magnetic recording of a bit string “0010011001000” will be described. As shown in FIG. 3A, “0” and “1” are expressed depending on whether there is a data bit between frame bits. At the time of reading, as shown in FIG. 3B, the frame bit and the data bit are separated. Then, information (ticket information) indicated by the data bits is reproduced.
[0034]
The point of the present invention is that the frame bit is used as a scale of the ticket medium, and the position of the punch hole is detected using this scale. To briefly explain an example, a clock is generated from a frame bit, and this clock is used as a scale of a ticket medium. Alternatively, the clock generated from the frame bits is multiplied to generate a finer multiplied clock, and this multiplied clock is used as the scale of the ticket medium. A more detailed scale can be obtained by using a multiplied clock than by using a simple clock.
[0035]
In the ticket medium, the magnetic polarity is reversed at the front and rear ends of the punch hole. Using this characteristic, the presence of a punch hole is detected. That is, the presence of a punch hole is detected by the reading head. The position of the punch hole on the ticket medium can be detected from the number of clocks generated from the frame bits by the time when the presence of the punch hole is detected. That is, it becomes possible to detect the distance from one end of the ticket medium to the position of the punch hole.
[0036]
Further, detection of punch hole positions by area division will be described.
[0037]
As shown in FIG. 5, the ticket medium is divided into N areas in the transport direction. That is, the ticket medium is divided into area 1, area 2,..., Area (N-1), and area N with respect to the transport direction.
[0038]
If an attempt is made to simply detect the position of a punch hole using a frame bit, the position detection accuracy may be lowered due to the influence of variations in the recording density of the frame bit. The variation in the recording density of the frame bits means the variation for each ticket medium. Therefore, the recording density is corrected using the total number of frame bits of the ticket medium and the total length of the ticket medium (the length of the frame bits in the recording direction). For example, the total length of the ticket medium (the length in the recording direction of frame bits) is L [mm], and the total number of frame bits is A [bits]. That is, the recording density is defined as A / L [bit / mm]. As described above, when the ticket medium is divided into N areas in the transport direction, the length of one area is L / N [mm]. That is, as shown in FIG. 5, the boundaries between the areas are L / N, 2L / N, 3L / N,..., (N-2) L / N, (N-1) L / N [mm]. Become. Each boundary is multiplied by the density (A / N), and the boundary value is converted into the number of bits and used for determination. That is, the 0th bit to the {(A / L) (L / N)} bit of the frame bits are the area 1. The {(A / L) (L / N) +1} bit to the {(A / L) (2L / N)} bit of the frame bits are the area 2. The {(A / L) (2L / N) +1} bit to the {(A / L) (3L / N)} bit of the frame bits are the area 3. Then, the {(A / L) ((N−1) L / N) +1} bit to the {(A / L) (NL / N)} bit of the frame bits are the area N.
When the presence of a punch hole is detected, the frame bit is {(A / L) ((N-2) L / N) +1} bit to {(A / L) (N-1) L / N) } If it is between bits, it is determined that the position of the punch hole is the area (N-1).
[0039]
Actually, a standard value of the total number of bits A is determined, and several types of boundary value tables for area division of −3 to +3 are calculated in advance with respect to the standard value and used for determination. When the value of A is finally determined, which table is to be validated is finally determined.
[0040]
Next, the punch hole position detection unit 60 will be described with reference to FIG. The punch hole position detection unit 60 is included in the reading circuit 44 shown in FIG. As shown in FIG. 6, the punch hole position detection unit 60 is provided with a demodulation circuit 61, a multiplication circuit 62, a punch hole determination circuit 63, a CPU 64, and a counter 65.
[0041]
The read heads 14 and 15 read the magnetic recording on the ticket medium and output it as a read signal to the demodulation circuit 61 and the punch hole determination circuit 63. The demodulation circuit 61 extracts a frame bit from the read signal and generates a frame clock. Then, the demodulation circuit 61 outputs the frame clock to the multiplication circuit 62. The multiplier circuit 62 multiplies the frame clock to generate a multiplied clock. Then, the multiplier circuit 62 outputs a multiplied clock to the counter 65. The counter counts the multiplied clock.
[0042]
The punch hole determination circuit 63 detects the presence of a punch hole from the read signal and outputs a detection signal (interrupt signal). Since the magnetic polarity is reversed at the front and rear ends of the punch hole, the presence of the punch hole is detected from the read signal using this characteristic. The CPU 64 reads the count value of the counter 65 at the timing of receiving the interrupt signal, and determines the position of the punch hole on the boarding ticket medium. The determination result of the punch hole position is provided to the main CPU 40 and reflected in the ticket gate process. Further, in the case of detecting the position of the punch hole by the area division described above, data relating to the area division is provided to the CPU 64. Then, the CPU 64 determines in which area the punch hole is present from the data regarding the area division and the count value of the counter 65 obtained at the timing of receiving the interrupt signal.
[0043]
Next, punch hole position detection will be described with reference to the flowchart of FIG.
[0044]
Here, it is assumed that the ticket information is recorded with a data structure having a frame bit and the punched hole is formed, and the length of the recording direction of the frame bit is L [mm]. To do. The ticket medium is received at the slot 3 and is conveyed along the recording direction of the frame bit on the main conveyance path 11 (ST1). The magnetic record of the transported ticket medium is read by the read heads 14 and 15 (ST2). Then, the demodulating circuit 61 extracts frame bits from the read magnetic recording (ST3). Further, the demodulation circuit 61 generates a clock from the extracted frame bits (ST4). Further, the multiplier circuit 62 generates a multiplied clock from the generated clock (ST5). The generated multiplied clock is counted by the counter 65 (ST6).
[0045]
The punch hole determination circuit 63 detects the presence of a punch hole from the read signals read by the read heads 14 and 15 and outputs a detection signal (interrupt signal). The CPU 64 reads the count value of the counter 65 at the timing of receiving this interrupt signal, and determines the position of the punch hole with respect to the transport direction in the boarding ticket medium (ST7). Alternatively, in the case of detecting the position of the punch hole by the area division described above, the data regarding the area division is provided to the CPU 64. Then, the CPU 64 determines in which area the punch hole is present from the data relating to this area division and the count value of the counter 65 obtained at the timing of receiving the interrupt signal (ST7).
[0046]
According to the present invention described above, the position of the punch hole can be accurately detected without being affected by transport slip or stall in the transport mechanism by using the encoded frame portion on the ticket medium as a reference. it can.
[0047]
In addition, by correcting the encoding recording density based on the number of frame bits recorded on the ticket medium, the position of the punch hole can be accurately determined even if the standard encoding recording density differs for each ticket medium. Can be detected.
[0048]
In this embodiment, the ticket medium is described as an example in which punch holes are formed, but the present invention is not limited to this, and can be applied to various prepaid cards.
