Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a card recording/reading method,
In particular, it relates to a recording/reading method that performs these processes in a short time when card information is recorded and read by the same information input/output unit.

[Prior art] Card recording/reading devices include perforated card recording/reading devices commonly used in computer input/output devices, OCR (optical character reading devices) that read numbers, letters, and symbols printed on cards; There are mark reading devices that read marks on cards, and magnetic ink character reading devices that read numbers, letters, and symbols recorded with magnetic ink on cards.

Normally, when cards are inserted one after another automatically from the input hopper or manually from the insertion slot, the cards wait at a wait station and receive information recording or reading commands. The data is sent to the output section (recording/reading section) and subjected to recording or reading processing. Once the processing is complete, it is sent to a kick station and discharged into a stacker.

In addition, normally the information input/output section is fixed, and the card is conveyed to perform recording and reading processing, but after the card is inserted, the information input/output section is fixed and the information input/output section moves to perform recording and reading processing. There is also.

Furthermore, there are cases in which recording and reading processing for the card is performed on all of the information on the card, and cases in which it is performed on only a portion of the information.

FIG. 1 is a diagram illustrating an example of this type of conventional card recording and reading system.

First, insert card 2 from card insertion slot 3,
When the card 2 is further conveyed in the direction of the arrow and the leading edge of the card 2 reaches the position of the magnetic head 1, reading RD of the card information is started, and when the other end (rear end) of the card 2 passes the magnetic head 1. Finish reading. Next, when recording new information on that card 2, move the card 2 to the recording start position (tip of the card).
The paper is conveyed in the reverse direction until it reaches that point, and from that point on, recording WT is performed in the same way as for reading. Next, read RD (CHK) for confirmation after recording is carried out in the reverse direction to the reading start position (the leading edge of the card) in the same way as before, and then read RD (CHK) as shown by the arrow at the right end. CHK). After confirmation, card 2
is ejected from the card ejecting section 4.

In this way, in the example in Figure 1, reading RD, recording
All three processes, WT and confirmation reading RD (CHK), are processed on the outward path from the tip of card 2 (transportation in the same direction as insertion), so the card needs to be transported as many times as the arrows in the figure (5 times). shall be.

[Problem to be solved by the invention]

However, in the conventional card recording/reading method, information recording/reading processing is performed only when the card is conveyed in one direction of insertion, so after recording the information, the recorded information is When checking the contents by reading the card, it is necessary to transport the card in the opposite direction, passing through the recording/reading section and transporting it to the reading start position.During this transportation period, processing such as recording and reading is performed. However, there was a problem that time was wasted and the processing time became unnecessarily long.

In the example of Figure 1, as mentioned above, read RD,
In order to carry out the three processes of recording WT and confirmation reading RD (CHK), it is necessary to transport the card five times as indicated by the arrow, and furthermore, no processing is performed on the return trip (transportation in the opposite direction to insertion). There was a drawback that I was wasting my time because there was no such thing.

SUMMARY OF THE INVENTION In order to eliminate the above-mentioned problems, an object of the present invention is to provide a card that can effectively utilize the transport path and eliminate wasted time when recording and reading information on the same card multiple times. record·
The purpose is to provide a reading method.

[Means to solve the problem]

In order to achieve the above object, the card recording/reading method of the present invention involves reciprocating one of the information input/output section and the card so that the information input/output section records or reads card information on the card. In a card recording/reading method that is performed multiple times, card information is read during the entire section from the leading edge of the card to the rear end in the forward direction, and card information is read in the traveling process from the rear end of the card to a position midway through the card. The present invention is characterized in that the card information is sequentially recorded during the movement process of the card, and the card information is sequentially read during the movement process in the forward direction over the entire section from the intermediate position of the card to the rear end of the card.

[Effect]

According to this type of card recording/reading method, a series of processes such as reading card information and recording/reading only a part of the card information can be performed in a continuous round-trip movement process, compared to the conventional one-way The processing time can be significantly reduced compared to when recording and reading processing is performed during the movement of the paper.

〔Example〕

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

FIG. 2 is an exploded view illustrating the principle of the present invention using an example in which recording and reading processing is performed three times over the entire section from the leading edge to the trailing edge of the card using a magnetic head. 2b shows the card insertion and the first reading/recording process, FIG. 2b shows the next recording/reading process, and FIG. 2c shows the final reading/recording and ejecting process. In the figure,
R in R/W stands for "reading" and W stands for "recording".

In FIG. 2a, the card 2 is first inserted into the card insertion slot 3, and when the card 2 reaches the position shown by the solid line, the magnetic head 1 starts reading, for example, and moves to the position R STA, shown by the chain line. End reading when R END is reached. That is, the card information of the entire section from the leading end of the card 2 to the other end (rear end) is read.

When the first process is recording W, start recording from the position of the solid line in exactly the same way, W STA,
W END ends recording at the position indicated by the chain line.

In FIG. 2b, recording or reading is performed when the card 2 is conveyed from the final state of FIG. 2a in the opposite direction to that at the time of insertion. In other words, the reading end R END position in Figure 2 a (dashed line in Figure 2 a) becomes the recording start W STA position in Figure 2 b (solid line in Figure 2 b), and the card is moved in the direction of the arrow. Recording is performed while conveying the card 2, and at the position indicated by the chain line, the entire recording of the entire section from the rear end to the front end of the card 2 ends (W END (ALL)).

In the case of full-page reading R (ALL), processing is performed in exactly the same manner as in the case of full-page recording.

In this case, when recording or reading is performed during transport in the opposite direction to the insertion direction, the order of the information to be recorded or read is naturally input/output in the reverse order of the processing in the insertion direction. In general, it is easier to process if read data is output in the normal order and recorded data is input in the reverse order, but it is also possible to process the recorded data in the normal order and the read data in the reverse order. Furthermore, it is also possible to perform both reading and recording processing without making them correspond to the forward and backward passes.

FIG. 2c shows a reading process in which recording is confirmed as the final process. The operation is the same as that shown in FIG. 2a.

After confirmation, the card 2 is ejected from the card ejecting section 4. If an error is confirmed, the operations shown in FIG. 2b and c are repeated. In addition, in Fig. 2 a, b, and c,
Although the card 2 is moved, it is of course applicable to a case where the card 2 is fixed and the information input/output section (magnetic head 1) is moved.

Through such a series of operations, in the present invention, the same processing can be performed in about half the total moving distance of the conventional method, eliminating wasted time and shortening the processing time. Also, the number of times the magnetic head contacts the card is reduced, so the lifespan of both the head and card is extended.

The above is an explanation of the basic configuration and operation of the present invention.

Here, when the first process is the recording WT process, it is common to perform the two processes alternately, so that the next process is the read RD process for confirmation.
The present invention is not limited to the case where the recording process and the reading process are performed alternately in this way, but may be a case where the recording process or the reading process is performed continuously two or more times.

FIG. 3 is an exploded view illustrating an embodiment of the present invention, in which partial recording/reading processing is performed using a magnetic head. Figure 3 is similar to Figure 2,
Figure 3a shows the card insertion and first reading/recording process, Figure 3b shows the next recording/reading process, and Figure 3c shows the final reading (confirmation)/recording and ejecting process. .

In Fig. 3a, first, card 2 is inserted into card insertion slot 3 and transported as is (outbound).
When the card 2 reaches the position indicated by the solid line, the magnetic head 1 starts reading, for example.
STA, R END to end reading when the dashed line position is reached. That is, the card information of the entire section from the leading edge to the trailing edge of the card 2 is read.

In FIG. 3b, recording is performed when the card 2 is transported in the opposite direction (return path) from the final state shown in FIG. 3a. That is, the end of reading R in FIG.
The END position (dashed line in Figure 3a) becomes the recording start W STA position (solid line in Figure 3b) in Figure 3b, and recording is performed while conveying the card 2 in the direction of the arrow. As shown by the chain line in Figure b, the recording ends at the middle position of the card W END (PART)
becomes. As a result, partial recording of a part of the section from the rear end of the card 2 to the middle position W END (PATR) of the card 2 is performed.

Here, in FIG. 3b, the recording end position (dashed line in the figure) is shown on the right side of the recording start position (solid line in the figure), but this is shown for convenience of explanation and is not originally intended. Recording start position and card insertion slot 3
Move along the conveyance path that connects the

Furthermore, when recording is performed when the paper is transported in the opposite direction to that at the time of insertion, as in the case of Figure 2, the order of information to be recorded is naturally input/output in the reverse order of processing in the insertion direction. . In general, it is easier to process if read data is output in the normal order and recorded data is input in the reverse order, but it is also possible to process the recorded data in the normal order and the read data in the reverse order. Furthermore, it is also possible to perform both reading and recording processing without making them correspond to the forward and backward passes.

FIG. 3c shows a reading process in which recording is confirmed as the final process. As for the operation, the end position shown by the chain line on the right side of Figure 3b is the reading (confirmation) start R CHK STA
(PART) position (solid line in Fig. 3c), and the card 2 is moved in the direction of the arrow to perform the reading process. Thereby, partial reading of a part of the section from the middle position of the card 2 to the end of the card 2 is performed.

After confirmation, the card 2 is ejected from the card ejecting section 4. If an error is confirmed, repeat the operations shown in FIGS. 3b and 3c. Although the card 2 is moved in FIGS. 3a, b, and c, the present invention can of course also be applied to a case where the card 2 is fixed and the information input/output section (magnetic head 1) is moved.

As described above, in the embodiment of the present invention shown in FIG. 3, a case has been described in which the entire card information is first read by moving the whole area, and then partial recording and partial reading is performed by moving a part of the area. Even when processing is performed by changing the order of the recording processing, the card 2 is transported and processed in exactly the same manner.

Through such a series of operations, in the embodiment shown in Fig. 3, the same processing can be performed with a much smaller moving distance than the conventional total moving distance, eliminating wasted time and significantly reducing processing time. be shortened. Additionally, the number of contacts between the magnetic head and the card is reduced, thereby extending the life of both the head and the card.

The method of the present invention assigns a certain value to the card and reduces that value each time it is used.
It is extremely effective if it is used when processing needs to be done in a short period of time, such as for instant notification of telephone charges.

〔Effect of the invention〕

As explained above, according to the present invention, when rewriting only a part of the entire card information, checking the reading, etc., the information input/output section moves the card back and forth in correspondence with only the required information position, Since only that part is recorded and read, processing time is shortened.
Furthermore, the amount of contact between the magnetic head and the card and the number of times of contact are minimized, which has the effect of lengthening the life of both.

Specifically, if you want to give a certain value to the card mentioned above and reduce that value each time it is used, first read the card information for all sections of the card necessary for use, and then Since only the value reduced due to use is partially recorded in a section of the card and the confirmation reading is performed sequentially, by applying the method of the present invention, processing time can be significantly shortened, and the magnetic head and card can be separated. Even when used repeatedly, the effect of greatly extending the life span can be obtained.
