The cut sheet is, for example, a form such as a bill or a check. On the single sheet paper targeted by the reading device 100 of the present embodiment, characters such as a user's account number and a serial number of a form are printed by a MICR (Magnetic ink character recognition) method. The MICR method printing is the printing of a MICR font at a predetermined position on a single sheet paper using magnetic ink or magnetic toner. Examples of MICR fonts include E13B fonts and CMC7 fonts. In the following description, the printing of the MICR method is referred to as MICR data. The reading device 100 of the present embodiment reads the MCUR data from the cut sheet.

The control unit 110 is composed of a processing device such as a processor. The control unit 110 functions as a control device that controls each unit of the reading device 100. The control unit 110 may be composed of one processor or a plurality of processors. When the control unit 110 is composed of a plurality of processors, the plurality of processors may be arranged at remote locations (for example, different boards) in the reader 100. The control unit 110 operates according to a program stored in a ROM (Read Only Memory) or a RAM (Random Access Memory) inside or outside the control unit 110, and various operations including a read process described later are performed. To realize. The concept of a program also includes a microprogram using microcode.

FIG. 4 is a functional block diagram showing the functions of the control unit 110. The control unit 110 has functions as a transport control unit 111 and a print control unit 112. These functional blocks (convey control unit 111, print control unit 112) may be software blocks or hardware blocks. For example, each functional block shown in FIG. 4 may be one piece of hardware (for example, one processor or one circuit block on a semiconductor chip (die)). Of course, one functional block may be realized by the cooperation of a plurality of processors. Further, the control unit 110 may be used as one processor, and each functional block may be realized by software (including a microprogram). Even when each functional block is realized by software, it is possible to configure the control unit 110 with a plurality of processors. The transport control unit 111 functions as a transport control means of the reader 100, and the print control unit 112 functions as a print control means of the reader 100.

The paper transport path 120 is a path for transporting single-cut paper. FIG. 5 is a diagram showing an internal structure of the reading device 100. The reading device 100 has a paper setting table for the user to set the cut sheet S. The paper set table has a curved portion that curves gently upward. The paper transport path 120 of the present embodiment extends upward from the curved portion. In the following description, the paper set table side (lower side of the drawing) of the paper transport path 120 is referred to as upstream, and the opposite side (upper side of the drawing) is referred to as downstream. A paper reversing portion 180 is arranged upstream of the paper transport path 120.

The transport unit 130 is a device for transporting the cut sheet S along the paper transport path 120. The transport unit 130 functions as a first transport means of the reading device 100. The transport unit 130 can transport the cut sheet S both upstream and downstream. In the following description, transporting the cut sheet S downstream by the transport unit 130 is referred to as forward rotation transport, and transporting the cut sheet S upstream by the transport unit 130 is referred to as reverse transport.

The transport unit 130 is arranged at the uppermost stream of the paper transport path 120. The transport unit 130 takes the cut sheet S from the paper set table into the paper transport path 120 into the cut sheet S by forward rotation transport. Alternatively, the transport unit 130 takes out the cut sheet S from the paper reversal unit 180 by forward rotation transport and takes it into the paper transport path 120. Further, the transport unit 130 feeds the cut sheet S to the paper set table or the paper reversal unit 180 by reverse transport.

The transport unit 130 includes a roller 131 and a roller 132. The roller 131 is a drive roller that is rotated by a drive means (for example, a DC motor) (not shown), and the roller 132 is a passive roller that presses the cut sheet S against the roller 131. The configuration of the transport unit 130 is merely an example, and various modifications are possible. For example, both the rollers 131 and 132 may be drive rollers.

The sensor 140 is a sensor that detects the edges T1 and T2 of the cut sheet S. As shown in FIG. 5, the end portion T1 is the end portion on the front end side (advancing side) when the cut sheet S is taken into the paper transport path 120 from the paper set table, and the end portion T2 is on the opposite side. It is the end. The sensor 140 includes a downstream paper detection sensor 141 and an upstream paper detection sensor 142. Both the downstream paper detection sensor 141 and the upstream paper detection sensor 142 are installed in the paper transport path 120. The downstream paper detection sensor 141 is installed between the transport unit 130 and the print unit 160 (that is, downstream of the transport unit 130 and upstream of the print unit 160), and the upstream paper detection sensor 142 is in front of the transport unit 130 (conveyance). It is installed upstream of the unit 130). The downstream paper detection sensor 141 and the upstream paper detection sensor 142 are, for example, optical sensors. The downstream paper detection sensor 141 and the upstream paper detection sensor 142 each detect the end portion of the cut sheet S and notify the control unit 110. The control unit 110 detects that the cut sheet S has passed the installation position of each sensor based on the notifications of the downstream paper detection sensor 141 and the upstream paper detection sensor 142.

The reading unit 150 is a device that reads information from the cut sheet S. The reading unit 150 of this embodiment reads MICR data from the cut sheet S. The reading unit 150 includes a reading head 151 and a head retainer 152. The reading head 151 is a magnetic head that reads MICR data. The head retainer 152 is a pressing member that presses the cut sheet S against the reading head 151. A magnet 153 for magnetizing the MICR data of the cut sheet S is arranged in the paper transport path 120. The magnet 153 magnetizes the MICR data before the cut sheet S reaches the reading unit 150. The reading head 151 reads the magnetized MICR data.

The printing unit 160 is a printing device for printing various information (for example, endorsement of a check) on the cut sheet S. The printing unit 15 is, for example, a dot impact type printing unit. The printing unit 160 includes a shaft 161, a carriage 162 that can reciprocate along the shaft 161 and a printing head 163 fixed to the carriage 162.

The route switching unit 170 is a device for switching the transport route of the cut sheet S. The route switching unit 170 is, for example, a flapper. The route switching unit 170 switches the route of the cut sheet S to either the paper set table side or the paper reversing unit 180 side according to the control of the control unit 110.

The paper reversing unit 180 is a device for reversing the cut sheet S. The paper reversing section 180 includes a reversing transport section 184 and rollers 185a to 185d. The reverse transfer unit 184 includes an endless transfer belt 184c and rollers 184a and 184b for driving the transfer belt 184c. The reverse transfer unit 184 (at least one of the rollers 184a and 184b) is driven by a stepping motor. The reverse transfer unit 184 functions as a second transfer means of the reading device 100. The reverse transfer unit 184 and the rollers 184a and 184b are arranged inside the cavity formed by the housings 182 and 183. This cavity has an entrance / exit 181 that connects to the paper transport path 120. Inside the cavity, a loop-shaped (oblong-shaped in the example of FIG. 5) inverted transport path that makes one rotation from the entrance / exit 181 along the transport belt 184c is formed. The cut sheet S inserted from the doorway 181 travels in the reverse transport path by the reverse transport unit 184, and is sent out from the doorway 181. In the following description, the transfer of the cut sheet S by the reverse transfer unit 184 (second transfer means) is referred to as reverse transfer.

Next, the operation of the reading device 100 having such a configuration will be described.

When the upstream paper detection sensor 142 detects the cut sheet S, the control unit 110 of the reading device 100 starts the reading process. As shown in FIG. 4, the control unit 110 functions as a transport control unit 111 and a print control unit 112. Hereinafter, the reading process will be described with reference to the flowchart of FIG.

The transport control unit 111 controls the transport unit 130 to forward-rotate the cut sheet S (ACT101). As a result, the cut sheet S is drawn from the paper set table into the paper transport path 120 and is transported downstream along the paper transport path 120.

Next, in the transport control unit 111, whether the upstream paper detection sensor 142 has detected the end portion T2 of the cut sheet paper S, that is, the end portion T2 of the cut sheet paper S has passed the installation position of the upstream paper detection sensor 142. (ACT102). When the upstream paper detection sensor 142 does not detect the end portion T2 of the cut sheet S (ACT102: No), the transfer control unit 111 continues the normal rotation transfer of the cut sheet S. When the upstream paper detection sensor 142 detects the end portion T2 of the cut sheet S (ACT102: Yes), the transfer control unit 111 stops the normal rotation transfer of the cut sheet S. FIG. 7 shows how the end portion T2 of the cut sheet S has passed the installation position of the upstream paper detection sensor 142.

Subsequently, the transport control unit 111 controls the transport unit 130 to reversely transport the cut sheet S (ACT103). FIG. 8A is a timing chart showing the transport speed of the transport unit 130 (first transport means). The vertical axis V is the transport speed of the transport unit 130, and the horizontal axis t is the elapsed time from the start of pulling in the cut sheet S. t1 is the timing at which the upstream paper detection sensor 142 detects the end portion T2 of the cut sheet S in the ACT 102.

The transport control unit 111 normally rotates and transports the cut sheet S at the transport speed A until the time t1, and then stops the transport of the cut sheet S at one end. After that, the transport control unit 111 reversely transports the cut sheet S at the same transport speed A as during the normal rotation transport. At this time, the transport control unit 111 controls the route switching unit 170 to switch the transport path of the cut sheet S from the paper set table side to the paper reversing unit 180 side. Further, the transport control unit 111 controls the reading unit 150 to start reading information from the cut sheet S. The cut sheet S is sent out from the paper transport path 120 to the paper reversing unit 180, and the MCUR data is read by the reading unit 150.

The transfer control unit 111 operates the reverse transfer unit 184 of the paper reversal unit 180 in accordance with the reverse transfer of the cut sheet S. FIG. 8B is a timing chart showing the transport speed of the reverse transport unit 184 (second transport means). The vertical axis V is the transfer speed of the reversing transfer unit 184, and the horizontal axis t is the elapsed time from the start of drawing the cut sheet S. t1 is the timing at which the upstream paper detection sensor 142 detects the end portion T2 of the cut sheet S in the ACT 102.

As shown in FIG. 8B, the transport control unit 111 maintains the transport stopped state until the time t1. Then, at substantially the same timing (t1 shown in FIG. 8B) as the timing at which the conveying unit 130 starts the reverse conveying (t1 shown in FIG. 8A), the inverted conveying unit 184 reversely conveys the cut sheet S. To start. At this time, the transport control unit 111 reversely transports the cut sheet S at a transport speed B1 faster than the transport speed A of the transport unit 130. The transport speed B1 is, for example, 1 to 20% faster than the transport speed A, preferably 1 to 10% faster. FIG. 9 shows how the cut sheet S enters the paper reversing section 180 from the paper transport path 120. Since the transfer speed of the reverse transfer unit 184 is faster than the transfer speed of the transfer unit 130, tension is applied to the cut sheet S. As a result, the paper wrinkles of the cut sheet S are reduced.

Next, the transport control unit 111 determines whether or not the upstream paper detection sensor 142 has detected the downstream end (end T1 in the example of FIG. 9) of the cut sheet S (ACT104). When the upstream paper detection sensor 142 does not detect the downstream end of the cut sheet S (ACT104: No), the transfer control unit 111 continues the reverse transfer and reverse transfer of the cut sheet S. When the upstream paper detection sensor 142 detects the downstream end of the cut sheet S (ACT104: Yes), the transfer control unit 111 stops the reverse transfer of the transfer unit 130. FIG. 10 shows how the end portion T1 of the cut sheet S has passed the installation position of the upstream paper detection sensor 142.

Then, the transport control unit 111 changes the transport speed of the reverse transport unit 184. Further, the transport control unit 111 starts forward rotation transport of the transport unit 130 (ACT105). The operations of the transport unit 130 and the reverse transport unit 184 will be described with reference to FIGS. 8 (A) and 8 (B). T2 shown in the figure is the timing at which the upstream paper detection sensor 142 detects the downstream end of the cut sheet S in the ACT 104.

As shown in FIG. 8A, the transport control unit 111 temporarily stops the reverse transport of the transport unit 130 (first transport means) at time t2. After that, the transport control unit 111 starts the forward rotation transport of the transport unit 130. At this time, the transport control unit 111 forward-rotates the cut sheet S at the same transport speed A as during reverse transport.

Further, as shown in FIG. 8B, the transport control unit 111 sets the reverse transport speed of the reverse transport unit 184 (second transport means) at time t2 to be slower than the transport speed A of the transport unit 130. Change to B1. The transport speed B2 is, for example, 1 to 20% slower than the transport speed A, preferably 1 to 10% slower than the transport speed A. FIG. 11 shows how the cut sheet S comes out from the paper reversing section 180 to the paper transport path 120. Since the transport speed of the transport unit 130 is faster than the transport speed of the reverse transport unit 184, tension is applied to the cut sheet S. As a result, the paper wrinkles of the cut sheet S are reduced.

Next, the transport control unit 111 determines whether the upstream paper detection sensor 142 has detected the upstream end (end T1 in the example of FIG. 11) of the cut sheet S (ACT 106). When the upstream paper detection sensor 142 does not detect the upstream end of the cut sheet S (ACT106: No), the transfer control unit 111 continues the normal rotation transfer of the cut sheet S. When the upstream paper detection sensor 142 detects the upstream end of the cut sheet S (ACT106: Yes), the transfer control unit 111 stops the forward transfer of the cut sheet S. FIG. 12 shows a state in which the end portion T1 of the cut sheet S has passed the installation position of the upstream paper detection sensor 142.

Subsequently, the transport control unit 111 determines whether or not the reading unit 150 has successfully read the MICR data with the ACT 103 (ACT 107). If the reading of the MICR data is not successful (ACT107: No), the transfer control unit 111 returns to the ACT 103 and reads the MICR data from the opposite side of the cut sheet S.

When the reading of the MICR data is successful (ACT107: Yes), the print control unit 112 controls the print unit 160 to print on the cut sheet S (ACT108). At this time, the print control unit 112 may adjust the print position on the cut sheet S by controlling the transport unit 130 based on the detection result of the downstream paper detection sensor 141. If printing is required on the opposite side of the cut sheet S, the transfer control unit 111 may execute ACT 103 to ACT 106 to reverse the cut sheet S.

When printing is completed, the transfer control unit 111 controls the route switching unit 170 and the transfer unit 130 to eject the cut sheet S in the paper transfer path 120 to the paper set table. When the ejection of the cut sheet S is completed, the control unit 110 ends the reading process.

According to the present embodiment, when the cut sheet S enters the paper reversing section 180 from the paper transport path 120, the transport control unit 111 transfers the reverse transport of the reversing transport unit 184 (second transport means) to the transport unit 130 ( The transport speed of the reverse transport unit 184 is controlled so as to be faster than the reverse transport of the first transport means). As a result, tension is applied to the cut sheet S during transportation, so that the paper wrinkles of the cut sheet S are reduced. As a result, paper jam, looseness of paper, and the like are reduced, so that the information reading error of the reading device 100 is small.

Further, when the cut sheet S comes out from the paper reversing unit 180 to the paper transport path 120, the transport speed of the reversing transport unit 184 is set so that the forward transport of the transport unit 130 is faster than the reverse transport of the reverse transport unit 184. I'm in control. As a result, tension is applied to the cut sheet S during transportation, so that the paper wrinkles of the cut sheet S are further reduced. As a result, paper jam and paper slack are further reduced.

Further, the transfer control unit 111 assumes that the transfer speed of the transfer unit 130 is the same during both forward rotation transfer and reverse transfer, and by changing the transfer speed of reverse transfer of the reverse transfer unit 184, tension is applied to the cut sheet S. Is added. Since the transfer control unit 111 only needs to control the transfer speed of the reverse transfer unit 184, the transfer control can be simplified. Since the transport speed of the transport unit 130 is constant and complicated speed control is not required, it is possible to use an inexpensive DC motor as the drive means of the transport unit 130.

Since the speed of the DC motor fluctuates with respect to the load, the transport speed of the cut sheet S is not stable when the DC motor is used as the driving means. However, in the present embodiment, the reversing transfer unit 184 is driven by a stepping motor. The rotation speed of the stepping motor is extremely stable. Therefore, the transfer speed of the reverse transfer unit 184 becomes stable.

When the cut sheet S enters the paper reversing section 180, the conveying speed of the reversing conveying section 184 is faster than the conveying speed of the conveying section 130. Therefore, the transport speed of the cut sheet S when the single sheet S enters the paper reversing section 180 is dominated by the transport speed of the reversing transport section 184. The reading unit 150 of the present embodiment reads information from the cut sheet S when the cut sheet S enters the sheet reversing unit 180. The reverse transfer unit 184 is driven by a stepping motor, and its transfer speed is stable. Therefore, the reading of the information of the reading unit 150 is also stable.

The above-described embodiment shows an example, and various modifications and applications are possible.

For example, in the above-described embodiment, the transfer control unit 111 applies tension to the cut sheet S by controlling the transfer speed of the reverse transfer unit 184 by setting the forward transfer and reverse transfer of the transfer unit 130 to a constant speed. It was. However, the transfer control unit 111 may apply tension to the cut sheet S by keeping the transfer speed of the reverse transfer unit 184 constant and controlling the speeds of the forward rotation transfer and the reverse transfer of the transfer unit 130. For example, the transfer control unit 111 sets the reverse transfer speed of the reverse transfer unit 184 to a constant speed, and when the cut sheet paper enters the paper reverse unit from the paper transfer path, the reverse transfer speed of the transfer unit 130 is set to the reverse transfer unit. It is slower than the transport speed of 184, and when the cut sheet paper comes out from the paper reversing section to the paper transport path, the forward rotation speed of the transport unit 130 is made faster than the transport speed of the reverse transport unit 184. Of course, the transport control unit 111 may control the transport speeds of both the transport unit 130 and the reverse transport unit 184.

Further, in the above-described embodiment, the printing unit 15 is assumed to be a thermal type printing unit, but the printing unit 15 is not limited to the thermal type printing unit. For example, the printing unit 15 may be a dot impact type, an inkjet type, or an electrophotographic type print unit.

Similarly, the printing unit 160 is not limited to the dot impact type printing unit. The printing unit 15 may be a thermal type, an inkjet type, or an electrophotographic type print unit. The printing performed by the printing unit 160 may be printing using magnetic ink or magnetic toner, for example, printing by the MICR method.

Further, in the above-described embodiment, the number of rollers constituting the transport unit 130 (first transport means) is two, but the number of rollers is not limited to two. The transport unit 130 may be composed of one or three or more rollers. Further, the transport unit 130 may be composed of a transport belt instead of a roller. Further, the motor that drives the transport unit 130 is not limited to the DC motor. For example, the motor that drives the transport unit 130 may be a stepping motor. The configuration of the transport unit 130 can be arbitrarily changed as long as the cut sheet S can be taken in from the paper set table or the paper reversing unit 180 and sent to the paper set table or the paper reversing unit 180.

Further, in the above-described embodiment, the reversing transport unit 184 (second transport means) is composed of a transport belt 184c and rollers 184a and 184b for driving the transport belt 184c. However, the configuration of the reversing transport unit 184 is not limited to this. For example, the reverse transfer unit 184 may be a transfer roller arranged along the loop-shaped reverse transfer path. Further, the motor that drives the transport unit 130 is not limited to the stepping motor. For example, the motor that drives the transport unit 130 may be a DC motor. The configuration of the reverse transfer section 184 can be arbitrarily changed as long as the cut sheet S can be conveyed along the reverse transfer path.

Further, in the above-described embodiment, the reading device 100 reads the MICR data from the cut sheet S, but the information read by the reading device 100 is not limited to the MICR data. The information read by the reading device 100 may be simply character information. In this case, the reading unit 150 may be an optical reading device. Of course, the information read by the reading device 100 may be magnetic data other than the MICR data.

Further, in the above-described embodiment, the reading device 100 is provided with a printing unit 160 for printing on the cut sheet S, but the reading device 100 is not necessarily provided with a device for printing on the cut sheet S. You may.

Further, in the above-described embodiment, the product information processing device 1 has a reading device 100 fixed or built in. However, the product information processing device 1 may be configured so that information can be read directly from the cut sheet S without going through the reading device 100. For example, the product information processing device 1 may directly include each unit (control unit 110 to paper reversing unit 180) included in the reading device 100.
