However, this type of printing device does not have a function to detect the printing, and only visually checks the printed receipt, so automatic teller machines and payment machines are unmanned machines, so there is no possibility of errors. It was impossible to detect the print.

(c) Problems to be solved by the invention The purpose of this invention is to provide a method for detecting printing errors that can detect printing errors even in unmanned machines such as automatic teller machines and payment machines. .

(d) Means for Solving the Problems This invention rotates a printing wheel with a plurality of printed characters on its circumference in a predetermined direction to select the printed characters, and moves the printing wheel in the printing direction to print one line. A printing device that performs printing, where the relative step pulse number from the previous printing position to the next printing is used as printing data,
One line of printing based on this printing data is stored in a memory, a reference position is set on the printing wheel, and when one line of printing starts, the printing wheel is aligned with the reference position, and then the printing data from the memory is read out to select type. After printing one line, the printing wheel is returned to the reference position, and the last digit is printed based on the number of pulses output at this time and the printing data stored in the memory. This is a printing error detection method that determines incorrect printing by comparing the position of the seal ring with the value obtained.

(E) Effect of the invention According to the present invention, the seal wheel rotation stop position of the last digit as execution data when the seal wheel was actually moved;
Misprinting is determined by comparing the software data of the printing wheel rotation stop position of the last digit calculated by software from the print data stored in the memory.

(f) Effects of the invention Therefore, if the two data match, it can be determined that normal printing has been performed, and if they do not match, it can be determined that printing has been erroneously performed, and erroneous printing can be reliably detected, and this can be done on the device side. This effect is effectively exhibited in printing devices used in unmanned machines such as automatic teller machines and payment machines.

The CPU 33 includes program memories 31 and 34 in which execution programs for each transaction process such as deposit and payment are stored in advance, and data memories 32 and 35 used for writing and reading transaction process data, respectively. When a command is sent from the M-CPU 30 to each S-CPU 33 as described later, each S-CPU 33 executes one of the programs stored in the memory 34 to perform the operation specified by the above command. It then controls each input/output device and sends necessary data generated during execution of this process to the M-CPU 30. Transaction processing data such as cash deposits and payments is M-
Information is transmitted from the CPU 30 to the center via the transmission control circuit 37, and necessary information is sent from the center to the M-CPU 30 via the transmission control circuit 37. The status and abnormalities of the deposit dispensing machine as displayed on the internal panel are also displayed on a remote monitor (not shown). Data transmission between the remote monitor and the M-CPU 30 is performed via the transmission control circuit 38. These transmission control circuits 37 and 38 include a line control circuit, a modulation/demodulation circuit, and the like.

Examples of a printing device included in the slip issuing machine 23 of such a deposit dispensing machine and printing transaction data on a receipt are shown in FIGS. 2 to 5. In these figures, a guide conveyance path for the receipt R is provided at the center of the substrate 40. This guide conveyance path includes a pair of guide plates 41 and a feed roller 42 provided so as to look into the guide path from one guide plate 41.
It consists of The feed roller 42 is fixed to a shaft 43 rotatably supported by support members 44 erected near both sides of the substrate 40 . The shaft 43 is rotationally driven by a suitable rotation means (not shown) or via a necessary mechanism (not shown) in conjunction with a digit return solenoid 95, which will be described later.

A guide shaft 55 of the movable body 51 is disposed between the support members 44.
A support shaft 59 of a hammer 58 is fixed, and a rotation shaft 54 of a printing wheel (print head) 50 is rotatably supported. A guide shaft 55 slidably passes through the movable body 51, and the movable body 51 is movable along the guide shaft 55. The movable body 51 has a pair of guide holding pieces 52 extending toward the seal ring 50 and an ink roller 53 that is rotatably provided. A rotating shaft 54 rotatably passes through approximately the center of the holding piece 52. The seal ring 50 is located between the pair of holding pieces 52 and is supported by the rotating shaft 54 so as to be movable in the axial direction thereof and to rotate together with the rotating shaft 54. Further, the seal ring 50 has a large number of printed characters such as letters and numbers to be printed on its circumferential surface. The above-mentioned ink roller 53 is in contact with the printed characters on the printing wheel 50 and constantly replenished with printing ink.

A return spring 45 is stretched between one side of the movable body 51 and one support member 44 along the pulley 46. The other side of the movable body 51 is connected to a drive pulley 49 by a pulling string 47 stretched along the pulley 46.
is tied to a part of Therefore, by rotating the drive pulley 49, the movable body 51 moves against the force of the spring 45, and as a result, the seal ring 50 held between the holding pieces 52 is also moved to the rotating shaft 54. Move along. Then, when the drive pulley 49 is brought into an idle state, the movable body 51 and the seal wheel 50 are returned to their original positions (indicated by I) by the force of the spring 45. A stopper 56 is fixed to the rotating shaft 54, and the return position I of the seal ring 50 is defined by the stopper 56.

The seal ring 50 moves from position I to position J as much as possible. Position I is the printing position for the first digit, which will be described later, and position K, which is one position before position J, is the printing position for the nth digit.

A gear 61 is fixed to the output shaft of the sealing wheel step motor 60, and this gear 61 is connected to an intermediate gear 62.
A gear 63 fixed to one end of the rotating shaft 54 via
It's meshing with each other. Motor 60 is fixed on substrate 40. Therefore, by rotating the motor 60, the seal ring 50 is rotated via the rotating shaft 54. Since the motor 60 is controlled by print data as will be described later, the printing wheel 50 is rotated and positioned so that the characters to be printed are in a position facing the hammer 58 for each printing operation.

The carry solenoid 65 moves the pulley 4 for each print.
Rotate the seal ring 50 by the required angle pitch.
The hammer 58 is driven in cooperation with the printing electromagnet 80 while moving it in pitch increments of digits. Both the solenoid 65 and the electromagnet 80 are fixed on the substrate 40. solenoid 65
The rod 66 is normally retracted and protrudes when energized. At the tip of this rod 66, the intermediate point of a link 67 whose one end is pivotally connected to the board 40 by a shaft 69 is pivotally connected by a shaft 70. Link 6
The other end of 7 is connected to one end of lever 68 by a shaft 71. A claw 68a is provided at the other end of the lever 68.

The pulley 49 is rotatably provided on the base plate 40 by a shaft 78 together with a ratchet gear 77 provided below. The pulley 49 rotates together with the gear 77. A spring 7 is attached to the one end of the lever 68.
2 is provided, and this lever 68 is connected to its claw 6.
8a is always biased so as to mesh with gear 77. A pawl 73a of a lever 73 for position retention is engaged with the ratchet gear 77. This lever 73 has a shaft 74 at the end opposite to the claw 73a.
The pawl 73a is pivotally attached to the base plate 40 by a spring 75, and is biased by a spring 75 so that the pawl 73a always meshes with the gear 77.

When the solenoid 65 is energized, its rod 66 protrudes as shown by the arrow, and as a result, the lever 68 also protrudes via the link 67. At this time, lever 6
The claw 68a of No. 8 is pushed outward by the teeth of the gear 77. Then, when the solenoid 65 is de-energized and the rod 66 returns to its original position, the pawl 68a of the lever 68 catches the next tooth of the gear 77, moving the gear 77 clockwise one tooth pitch. Rotate by minute. When the lever 68 protrudes, its claw 6
Even if the gear 8a comes off the teeth of the gear 77, the claw 73a of the lever 73 is engaged with the teeth of the gear 77, so the gear 77 is held in that position without rotating backward.

A shaft 84 is fixed to the rod 66 of the solenoid 65 at a position slightly to the side of the solenoid 65, and an operating lever 81 is pivotally connected to the shaft 84 at one end thereof below the rod 66. This lever 81 has a pushing protrusion 83 at the tip of the other end,
Additionally, an adsorption piece 82 that is formed to stand up next to the electromagnet 80 is provided. The lever 81 is biased by a spring 85 in a direction in which the attraction piece 82 is moved away from the electromagnet 80 . On the other hand, viewed from one side, hammer 5
8 and the electromagnet 80.
A shaft 87 is fixed to the shaft 87, and the center point of the doglegged link 86 is pivotally connected to the shaft 87. A pin 89 is erected upward at one end of the link 86, and a U-shaped notch 90 is formed at the other end. The link 86 is constantly urged by a spring 88 in a direction in which the one end thereof moves away from the protrusion 83 of the lever 81 . The hammer 58 is attached to a support member 91, and this support member 91 is attached to a support shaft 59.
It is swingably supported by. Support member 9
1 has an engaging piece 92 facing the other end of the link 86 and engaging in the U-shaped notch 90.
is provided. Hammer 58 has a length from position I to position K.

Normally, the link 86 is biased by the spring 88 so that its other end faces toward the support member 91, so the lower end of the support member 91 is biased toward the conveyance path of the receipt R. Therefore, the hammer 58 is separated from the circumferential surface of the seal ring 50. Printing by the hammer 58 is performed in conjunction with the carry operation by the solenoid 65, and is performed immediately before the printing wheel 50 moves by one digit. When printing, the electromagnet 80 is energized, and the attraction piece 82 of the lever 81
is attracted to the electromagnet 80, so that the protrusion 83 of the lever 81 is moved in the direction of the electromagnet 80 against the force of the spring 85. At the same time as the electromagnet 80 is energized, the solenoid 65 is energized and its rod 66 is energized.
stands out. Since the lever 81 is connected to the rod 66 by a shaft 84, this lever 81 also projects. Therefore, the protrusion 83 of the lever 81 comes into contact with the pin 89 of the link 86 and pushes the end of the link 86 on this side of the pin 89. For this reason, link 8
6 moves in a direction away from the notch 90 against the force of the spring 88, and the lower end of the support member 91 also moves in the same direction. Therefore, the hammer 58 is the seal ring 50.
The receipt R is pressed against the printing wheel 50 by moving in the direction shown in FIG.

When the solenoid 65 and the electromagnet 80 are de-energized, the lever 81 and the link 86 release the spring 8
5 and spring 88 to return to the original position.

Even if carry is carried out by solenoid 65,
Unless the electromagnet 80 is energized, the lever 81 will not be attracted to the electromagnet 80, so the protrusion 83 will not push the pin 89 of the link 86, and no printing will be performed.

A return solenoid 95 is also fixed on the substrate 40. The rod 96 of this solenoid 95
is normally in a protruding state and retracts when energized. This rod 96 operates a return lever 99 located slightly below the ratchet gear 77 via links 97 and 98. Digit return lever 99
is pivotally connected to the shaft 74, and one end is connected to the link 98.
The other end extends below both levers 68 and 73. Pins 76 and 79 projecting downward are fixed to both levers 68 and 73, respectively, and these pins 76 and 79 are in contact with the outside of lever 99. The links 97 and 98 are pivotally connected to shafts 100 and 103 fixed to the base plate 40 at intermediate portions, respectively. One end of the link 97 is the solenoid 9
6. A pin 101 is provided at the other end of the link 97, and the pin 101 is inserted into an elongated hole 102 formed at one end of the link 98, thereby connecting both links 97 and 98.
The other end of link 98 extends toward one end of lever 99. Energize the solenoid 95 and close the rod 9.
6 is mixed in, the portion of the lever 99 that is in contact with the pins 76, 79 via the links 97, 98 is moved outward. Therefore, both the levers 68 and 73 also move in the direction away from the gear 77 against the force of the springs 72 and 75, respectively, and the claws 68a and 73a move away from the gear 77.
Move away from 7 teeth. As a result, the gear 77 and the pulley 49 are in an idle state. Therefore, the seal ring 5
0 returns to its original position by the force of spring 45.

FIG. 6 shows a control circuit for such a printing device. S-CPU that controls the slip issuing machine 29
33 outputs a print data signal, a digit return command, a carry command, and a print command via the input/output interface 110 to control the printing device. A reference position signal is output from the step motor 60 when the rotation angle of the motor reaches a predetermined reference position, and is sent to the step pulse counter 111. This counter 111 drives the motor 60 based on the print data signal and the reference position signal from the S-CPU 33 so that the characters on the seal wheel 50 represented by the print data come to a position facing the hammer 58. Drive pulse A,,
Outputs B. This drive pulse is driver 1
12 to the motor 60. When the positioning of the seal ring 50 by the motor 60 is completed, a set completion signal is output from the counter 111 and sent to the S-CPU 33 via the interface 110. Digit return commands, carry commands, and print commands from the S-CPU 33 are sent to each driver 113, 114,
115, and drive signals based on each command from these drivers are sent to the respective solenoids 95,
65 and electromagnet 80.

FIG. 7 shows a receipt printed by a printing device. The receipt R is provided with a plurality of lines of print fields P. And in each printing column P,
Print data of up to n digits (10 digits in this example) is printed. The rightmost digit in Figure 7 is the first digit (least significant digit)
The number of digits increases toward the left, and the nth digit (most significant digit) is located at the leftmost position. The printing wheel 50 of the printing device moves leftward from the position of the first digit and prints the data for each digit.

FIG. 8 shows S-- which controls the slip issuing machine 23.
A part of the data memory 35 of the CPU 33 is shown. A part of this memory 35 is provided with an area for storing print data for one line, and the data is stored in this area in the order of the address from the first digit (lowest digit) to the print data for one line. Print data up to the n-th digit (most significant digit) is stored. Let ma be the address where the first digit data is stored,
the address where the nth digit data is stored
Let it be MA.

Note that the above print data is not the number to be printed on the receipt, but the number of steps to drive the motor 60 from this position starting from the reference position of the printing wheel 50 to reach the printing position. Further, the step number in each digit other than the first digit indicates how many step motors 60 must be driven successively from the lower digit to obtain the printed characters.

In this embodiment, the seal ring 50 is provided with 12 printed letters on the circumferential surface, and these printed letters are, for example, 12 printed letters consisting of numbers "0" to "9" and three codes. Perform one rotation with the rotation of the step,
The position of the printed character "0" is set as the reference position.

When printing the number “3847521” shown in FIG. 7, printing starts from the least significant digit, and this first digit can be changed to “1” by rotating the printing wheel 50 one step from “0”. ” can be selected, and the second digit “2” can be printed by rotating the sealing wheel 50 one step from the above-mentioned “1” printing position. In this way, the printing wheels 50 are selected one after another, and therefore the printing The data will be the number of continued steps described above, as shown in FIG.

To explain the error printing detection operation based on FIGS. 9 and 10, when one line of print data is stored in the memory 35, the S-CPU 33 first determines whether or not the seal ring 50 is at the reference position. A check is made based on the presence or absence of a reference position signal from the motor 60. This reference position signal is a signal that is output when the number of "0"s on the seal wheel 50 is opposite to the printing position.

If the seal ring 50 is not at the reference position in the above check, reference positioning is performed. That is, 50 seal rings
Since one revolution consists of 12 steps, first, the number of 12 step pulses is set as print data in the counter 111, and a reference positioning signal is input.

The motor 60 is driven by the above-mentioned set to rotate the printing wheel 50, and when the reference position, that is, the character "0" is aligned with the printing position, the motor 60 outputs a reference position signal to the counter 11.
1 is stopped, and the counter 111 outputs a set completion signal.

When this signal is output, the S-CPU 33 executes a printing operation. That is, the address ma of the area where the print data of the lowest digit of the memory 35 is stored is stored in the index register IXR, and the data of the area designated by this address ma is read out, that is, the "1" of the lowest digit is read. The number of step pulses of "01" for printing a number is read and set in the counter 111.

With this setting, the motor 60 is driven one step, and the character "1" is made to face the printing position.

When the selection of type is completed, a set completion signal is output from the counter 111, and based on this output, the S
- The CPU 33 outputs a print command and a carry command, thereby causing the electromagnet 80 and the solenoid 6 to
5 is energized.

As a result, the adsorption piece 82 of the lever 81 is attached to the electromagnet 80.
At the same time, the rod 66 of the solenoid 65 protrudes, whereby the ring 86 and the hammer 58 contact the positioned type and the receipt R to perform printing.

When the solenoid 65 is deenergized and the rod 66 returns to its original position, the ratchet gear 77 is rotated by one pitch by the pawl 68a, so the printing ring 50 is moved in order to print the next digit. It is moved by one digit in the direction of the upper digit.

Next, add 11 to the contents of index register IXR.
Specify the address of the next printing digit and perform the next printing operation.

If such a printing operation is performed in sequence and it is confirmed that there is no print data in the print data area, it means that printing of all digits has been completed, and then error printing detection is executed.

First, based on the data in the print data area of the memory 35, the absolute position at the time of printing the last digit is determined. In other words, the data in the above area does not store the absolute position of the seal ring 50, but the relative number of step pulses from the previous printing position to the next printing, so based on this content, the last digit of the seal ring 50 Find the position of and store its value (number of step pulses) in B register BR.

For example, in the case of the data shown in FIG. 8, the total number of step pulses is summed using the B register. That is, the total number of step pulses is 27.

Since one cycle of the seal ring 50 has 12 step pulses, the subtraction by 12 is repeated until the above-mentioned total number becomes 12 or less. As a result, "3" step pulses remain, this number indicating the most significant digit character position, and is stored in the B register BR.

Next, it is checked whether the seal ring 50 is at the reference position based on the presence or absence of the reference position signal from the motor 60, and if the above-mentioned signal is output, "0" is stored in the A register AR.

Further, when the seal ring 50 is not at the reference position, reference positioning is executed.

In other words, the counter 111 receives the print data as print data.
12 Set the number of step pulses (the number of pulses for one rotation of the seal ring 50) and input the reference positioning signal.

The motor 60 is driven by the above-mentioned set to rotate the sealing wheel 50 and return to the reference position, that is, "0".
When the printed characters are aligned with the printing position, a reference position signal is output from the motor 60, driving of the counter 111 is stopped, and a set completion signal is output from the counter 111.

Then, the remaining count value of the counter 111 at this time is read out and stored in the A register AR.

For example, when the data shown in FIG. 7 is printed, the most significant digit is "3", and nine step pulses are required to move it to the reference position of "0".

For this purpose, when the counter 111 is set to the number of 12 step pulses and is driven for positioning, the remaining count value of the counter 111 becomes "3", the number of step pulses, and this "3" is stored in the A register AR.

When the value calculated based on the print data and the value when the seal ring 50 is returned to the reference position are output, the values in the A register AR and the B register BR are compared.

In the case of the above example, since "3=3", it is normal printing, and if these values do not match, it is determined to be erroneous printing.

In the case of normal printing, the S-CPU 33 outputs a digit return command, and the solenoid 95 operates to close the two pawls 6.
Since both 8a and 73a are removed from the ratchet gear 77, the printing wheel 50 returns to the original printing position I of the first digit by the action of the spring 45.

In addition, if there is a mismatch, the seal ring 50 is
is returned to the original printing position, but after that, the process ends with an error indicating that there was an error in printing, or it may not be an error by adding a symbol to the next line to indicate reprinting and printing the same content. It is possible.

When one line of printing is completed as described above and the next line is to be printed, the feed roller 42 is driven to feed the receipt R by one line and the above-described printing process is performed.
