Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a recording device for writing information on or reading information from an information card such as a perforated card or a magnetic card.

A feature of the present invention is that when the driving means for running the card is controlled in response to a detection signal of the card detecting means provided in the running direction of the card running path, the positional configuration of the card detecting means We have devised a new method.

Further, the drive means and the control of the recording section that reads or writes information are also characterized.

Conventionally, to explain this type of recording device, for example, a mark card reader device, as shown in FIG. 1, a card detector-1 is provided near the card insertion slot of the device, and when a card is inserted, the The device 1 detects the card and outputs a detection signal, and this detection signal drives a motor for driving the card.

The card is driven inward by the drive of the motor and reaches the reading section 2, where the card information is read.

Furthermore, the card is sent to the back of the travel path and reaches the second detector 3 provided at the end of the travel path. This second detector 3 detects that the card has reached the end of the travel path, and this detection signal causes the motor to reverse direction and send the card toward the card insertion slot, so that the card is removed from the insertion slot. It was configured to be ejected to

Therefore, in such a configuration, since the first detector, the reading section, and the second detector are individually provided, it is very troublesome to adjust the positions of these detectors and the reading section. This is even more the case when there are many.

In addition, in the case where the drive means etc. are directly controlled by the detection signal from the detector as described above, many devices are required to judge the running state of the card, making the hardware configuration complicated and cost-effective. It had drawbacks such as being expensive. The present invention provides a new recording device that solves the problems of the conventional devices as described above, and the present invention will be explained in detail below with reference to the drawings.

FIG. 2 is a diagram showing the relationship between the card running and the detection means according to the present invention using a mark card reader as an example. A device 1 is provided to detect that a card is inserted into the insertion slot.

This detector 1 receives light emitted from a light source 1A through a light receiving element 1.
An optical detector is shown at B, which can also be mechanical, such as a microswitch. A motor is driven in response to a detection signal from the detector 1, and the card is run to reach a recording means 2 (here, an optical reading device is shown).

This recording means 2 is arranged at a distance from the first detector 1 that is equal to or longer than the card length.

Further, the specific configuration of this recording means 2 is shown in FIG. 3, and the reading element group 2A is configured to read, for example, six units of information, and a second reading element group 2A is arranged in parallel with the reading element group 2A.
The card detecting means 3 is provided. Therefore, the recording means 2 shown in FIG. 2 includes a reading element group 2A and a second card detecting means 3 integrally.

This second card detection means 3 is optical, and may be mechanical, but is preferably an optical detection means.

This second card detection means 3 detects that the card has passed, and the motor is reversed in response to this detection signal.

For this reason, the card is made to travel in the opposite direction toward the card insertion slot. In the above configuration, since the recording means 2 is integrally equipped with the second card detector,
There is no need to arrange the first detector, recording means, and second detector in the same relationship as in the past, and it is only necessary to adjust the positions of the first detector and the recording means at two locations. By including the detector in the recording means, it has the advantage that it is structurally simple and can substantially eliminate the need for a conventional second detector. Next, the relationship between the first detector 1, the second detector 3, the running state of the card, and the recording means 2 will be specifically explained.

The running state of the card, that is, the position information when the card is running, is expressed by a code signal of a binary code, and the driving means (motor) for running the card and the recording means are controlled according to the state of this code signal. There is.

Figure 4 shows the relationship between the card position and the code signal corresponding to the position.
In this state, the first and second detectors 1 and 3 do not detect anything, so there is no detection signal, and the counter that is counted up sequentially in response to the detection signal is "0", that is, "000", and this The location information is "o".

Next, in state 8 when the operator inserts the card, the first detector 1 detects the leading edge of the card and this detection signal is introduced to the counter, so the counter is "1", that is, [001].
, and this position information is set as "1".

Next, in state O when the card passes the first detector 1, the first detector 1 detects the trailing edge of the card and this detection signal is introduced into the counter, so the counter is set to "2", that is, [0
10'', and this position information is set as ``2''.

Next, in the state 9 when the card reaches the recording means 2, the recording means 2
The second detection means 3 located at
In other words, it is "011", and this position information is set as "3".

Next, in state [F] when the card passes the recording means 2, the second detection means 3 in the recording means 2 detects the trailing edge of the card and this detection signal is introduced into the counter, so the counter is "4". ” In other words, it is “10,0” and this position information is “4
”.

Next, in the state [F] when the card returns to the recording means 2 again, the second detection means 3 detects the leading edge of the card, and this detection signal indicates that the counter is "5", that is, "1Q1". This position information is set as [5].

Next, in the state O when the card passes the recording means 2, the second detection means 3 detects the trailing edge of the card, and this detection signal indicates that the counter is "6", that is, "1:O", and this position information is set as "6".

Next, in the 0 state when the card reaches the first detector 1 again, the first detector 1 detects the leading edge of the card, and this detection signal indicates that the counter is "7", that is, "111", and this position The information is ``7''.

Next, in state 1 when the card passes through the first detector 1, the first detector 1 detects the trailing edge of the card, and this detection signal causes the counter to read "dan"("O"), or "000". , and this position information is "O".

The relationship between the running position information of this card and motor (drive means) control is set as follows.

The motor is stopped when the counter is "0"("000").

Also, when the counter is "1"("001"), the motor is driven in the forward rotation direction, and the counter is "3"("011").
Normal rotation drive is maintained until the state of .

Next, the motor is reversed when the counter is at "4"("100"), and the reverse drive is maintained until the counter is at "7" (November).

On the other hand, the control relationship between the card running position information and the recording system is set as follows.

Counter is [0] to “2” (“000” to [010”)
When , the operation of recording means 2 is prohibited and the counter reaches ``3''.
” (“011”), the recording means 2 operates.

Also, when the counter is [4] ("100"), the recording means 2
The operation of the recording means 2 is prohibited, and the operation of the recording means 2 is performed again when the counter is "5"("10U").

Furthermore, the operation of the recording means 2 is prohibited when the counter is between "6" and "7".

In this case, in the case of a magnetic card reader, when the counter is "3"("011"), the recording means 2 is caused to perform a writing operation, and when the counter is "5"("10U"), the recording means 2 is caused to perform a writing operation. It causes an action to take place.

Also, if you use a mark card reader, the counter's [3] or "$
It is also possible to cause the recording means 2 to perform the read operation. A specific configuration of the apparatus that performs the above operation is shown in FIG. 5, and the configuration of FIG. 5 will be described below. 1 is the first detector described above, and this detection signal is sent to the amplifier 51.
are introduced into the card's leading edge detector 52 and trailing edge detector 53, respectively.

3 is a second detection means, and this detection signal is passed through an amplifier 54 to a leading edge detector 55 and a trailing edge detector 56 of the card.
will be introduced respectively.

The respective outputs from the leading edge detectors 52, 55 and trailing edge detectors 53, 56 are sent to a counter 58 via an OR gate 57.
will be introduced in

The counter 58 is configured to count up by "1" each time an input signal arrives. Reference numeral 59 denotes a decoder, into which the binary code signal of the counter 58 is introduced and a control signal corresponding to the code signal is introduced into the driver circuit 61 of the motor 60 and the recording means 2.

The recording means 2 has a configuration for the mark card reader shown in FIG. 2 as two examples, and inputs the signal from the reading element group 2A to the gate means 62 via the amplifier 2B, and inputs the control signal from the decoder 59. This gate output serves as a read signal.

The specific construction of the leading edge detectors 52, 55 and trailing edge detectors 53, 56 of the card described above is shown in FIG.

A flip-flop F1 to which detection signals (FIG. 7A) from the first and second detection means via an amplifier are input, another flip-flop F2 provided after the flip-flop F1, a set output of the flip-flop F1, and a flip-flop It consists of an AND gate G1 into which the reset output of F2 is introduced, and an AND gate G2 into which the reset output of flip-flop F1 and the set output of flip-flop F2 are introduced.

The gate output of this AND gate G1 is a card leading edge detection signal, and the gate output of AND gate G2 is a card trailing edge detection signal.

That is, while flip-flops Fl and F2 are in the reset state and the detection means is detecting the card as shown in FIG. 7A, a detection signal having a logic level of "1" is introduced to flip-flop F1, When the detection means detects the leading edge of the card, the flip-flop F1
is set and outputs the signal shown in FIG. 7B.

The set output of flip-flop F1 makes AND gate G1 conductive and outputs a leading edge detection signal.

Further, when the set output of flip-flop F1 is input to flip-flop F2 and flip-flop F2 is set, the AND gate G1 becomes non-conductive. Therefore, the leading edge detection signal becomes the signal shown in FIG. 7D, and the set output of flip-flop F2 becomes the signal shown in FIG. 7C.

When the detector finishes detecting the card, flip-flop F1 is reset, and the output of the reset signal causes AND gate G2 to conduct and output a trailing edge detection signal.

Furthermore, the reset output of flip-flop F1 is introduced to flip-flop F2, and flip-flop F2 is reset, thereby making AND gate G2 non-conductive, resulting in the trailing edge detection signal shown in FIG. 7E. Next, to explain a little more about the operation shown in FIG.
does not output a detection signal, so the counter 58 is [000]
This code signal is introduced into the decoder 59, and the control signal from the decoder 59 stops the motor 60 and inhibits the operation of the recording means 2.

When the card is inserted into the insertion slot, the first detector 1 detects the card, and this detection signal is sent to the leading edge detector 52 (specifically, see FIG. 6 above), and the leading edge detection signal is sent to the leading edge detector 52. counter 5
8, the contents of the counter 58 are counted up by "1" and become "001".

In response to this counter state, the decoder 59 causes the motor driver circuit 61 to drive the motor 60 in the forward rotation, while still inhibiting the operation of the recording means 2. The motor 60
When the first detector 1 finishes detecting the card, a trailing edge detection signal is introduced from the trailing edge detector 53 to the counter 58, and the counter 58 becomes "010".

When this counter state is introduced into the decoder 59, the control signal from the decoder 59 causes the motor driver circuit 61 to drive the motor 60 in normal rotation and inhibits the operation of the recording means 2. In other words, the previous operation is continued. When the card is further run and reaches the position of the recording means 2, the second detection means 3 detects the card, and this detection signal is sent to the leading edge detector 55, and the leading edge detection signal is introduced to the counter 58. The counter 58 becomes "011". In response to this counter state, the decoder 59 causes the motor driver circuit 61 to continue driving the motor 60 in the normal rotation, and the recording means 2
start the operation.

As a result, the gate 62 of the recording means 2 becomes valid and reading of the card information is executed. Said second detection means 3
When the card has been detected, a trailing edge detection signal is introduced from the trailing edge detector 56 to the counter 58, and the counter 58 reaches "10".
0”. In response to this counter state, the decoder 59
causes the motor driver circuit 61 to perform reverse drive, causes the recording means 2 to prohibit its operation, and disables the gate 62. By the above operation, the motor 60 is reversed, and the card is now fed toward the insertion slot.

Then, the second detection means 3 detects the card and a leading edge detection signal is introduced from the leading edge detector 55 to the counter 58, and the counter 58 becomes "101". In response to this counter state, the decoder 59 causes the motor driver circuit 61 to continue the reverse rotation 1 drive and causes the recording means 2 to start its operation.

This causes the recording means 2 to read the card when it is moving backward. When the second detection means 3 finishes detecting the card, the trailing edge detection signal is introduced from the trailing edge detector 56 to the counter 58, and the counter 58 becomes "110".

In response to this counter state, the decoder 59 causes the motor driver circuit 61 to continue to drive in reverse, and also prohibits the operation of the recording means 2. When the card further moves toward the insertion slot and the first detector 1 detects the card,
A leading edge detection signal is input from the leading edge detector 52 to the counter 58, and the counter 58 becomes "111". In this counter state, the decoder 59 causes the motor driver circuit 61 to perform reverse driving and also prohibits the operation of the recording means 2. In other words, the previous operation is continued. When the first detector 1 finishes detecting the card, a trailing edge detection signal is input from the trailing edge detector 53 to the counter 58, and the counter 58 becomes "000".

Based on this counter state, the decoder 59 causes the motor driver circuit 61 to stop the motor 60 and prohibits the operation of the recording means 2. In this manner, the configuration shown in FIG. 5 executes the operations shown in FIG. 4.

As described above, in the present invention, an information card is conveyed from the card insertion slot position through the recording means for reading information on the card or writing information on the card, and the recording means In order to convey the information card to the insertion slot position through the position of In the information card recording device to be controlled, a first card detector disposed within a range shorter than the card length in the recording means direction from the card insertion slot position, and a first card detector arranged within a range shorter than the card length from the position of the first card detector. The recording means arranged with the above interval, and the second recording means integrally equipped with the recording means.
a card detector, a first detection circuit that detects a leading edge and a trailing edge of a card from a detection signal of the card detector and outputs a detection pulse corresponding to the first and second card detectors, respectively; a second detection circuit; a counter that sequentially counts outputs from the first and second detection circuits; and a counter that receives the counted value of the counter as position information on the travel path of the card, and according to this position information. The device is equipped with a control unit that drives and controls the driving means and recording means of the card to a set control state, and the second card detector is integrated with the recording means, so that the mounting of the recording means is easy. This allows simultaneous positioning, and the positional adjustment and arrangement of the first and second card detecting means becomes extremely simple, which is advantageous in terms of mounting structure.

In addition, in controlling the running of the card and controlling the recording means, a counter is used to count detection pulses from a detection circuit that detects the leading edge and trailing edge of the card corresponding to each card detecting means, and the counted value of the counter is calculated. Since the position information is used as the position information on the travel path of the card, an accurate position state of the card can be obtained, and the obtained position information is used to control the driving means and the recording means in a control state set in advance according to the position information. Therefore, it is possible to obtain an apparatus that can perform accurate and easy control without increasing the hardware configuration as in the conventional case, and is inexpensive.
