The output values of the temperature sensor 76 and the thermal head temperature sensor 77 are output to the CPU 101 as digital data. The CPU 101 determines the thermal head 16, the first print head 46, and the second print head based on the temperatures obtained based on the output values of the first print head temperature sensor 75, the second print head temperature sensor 76, and the thermal head temperature sensor 77. The print head 48 is controlled. Specifically, when the temperature of the thermal head 16, the first print head 46, and the second print head 48 exceeds a preset threshold, the CPU 101 forcibly suspends the operation of the head. . In this case, the CPU 101 restarts the operation when the temperature of the stopped head becomes lower than the set value.

The head drive circuit 111 causes the first print head 46 and the second print head 48 to perform recording on the check S by energizing the solenoid coil that causes the recording wire to protrude in accordance with the control of the CPU 101. Further, the head drive circuit 111 performs recording by energizing a heating element (not shown) included in the thermal head 16 according to the control of the CPU 101 and applying heat to the recording surface of the roll paper R.
The motor driver 113 includes a roll paper transport motor 17 configured as a stepping motor, a cutter drive motor 24, a slip transport motor 38, a roller opening / closing motor 39, a stopper drive unit 44a, a first carriage drive motor 54, and a second carriage drive motor. A drive power supply and a drive pulse are output to each motor 59 in accordance with the control of the CPU 101. The drive power supply that the motor driver 113 supplies to each motor is a 24V DC power supply that the power supply unit 120 supplies to each unit.
The power supply unit 120 includes each drive unit of the composite processing apparatus 1 illustrated in FIG. 4, that is, each print head (first print head 46, second print head 48, thermal head 16), and each motor (cutter drive motor 24, first print head). DC power is supplied to the carriage drive motor 54, the second carriage drive motor 59, the slip transport motor 38, the roll paper transport motor 17, the roller opening / closing motor 39), the stopper drive unit 44 a, and the control board 40. In addition, each sensor included in the combined processing apparatus 1 is supplied with power from the power supply unit 120 via the control board 40 or via the sensor drive circuit 109 mounted on the control board 40.
The output voltage of the power supply unit 120 is input to the sensor drive circuit 109, and the sensor drive circuit 109 outputs the voltage value of the power supply voltage of the power supply unit 120 to the CPU 101 as digital data. The CPU 101 determines whether or not the voltage of the power supply unit 120 is within the normal range based on this digital data.

  As described above, the composite processing apparatus 1 can execute MICR reading and printing on the check S and can execute printing on the roll paper R. Among these, the slip conveyance motor 38, the roller opening / closing motor 39, the alignment means 44, the first print head 46, the second print head 48, the first carriage drive motor 54, and the second that process the check S under the control of the control board 40. Each operation part of the carriage drive motor 59 is a slip operation part. The slip operation unit may include a slip printing unit 12. In addition, the operation units of the thermal head 16 that processes the roll paper R, the roll paper conveyance motor 17, and the cutter drive motor 24 are referred to as roll paper operation units. The roll paper operation unit may include the roll paper printing unit 13 described above.

Next, the operation of the composite processing apparatus 1 will be described. The operation described below is realized by the CPU 101 executing a program stored in the flash ROM 105.
The composite processing apparatus 1 shifts to a standby state after power is turned on. In this standby state, the roller opening / closing motor 39 moves the first transport roller 34 and the second transport roller 37 to the open position so that the check S can be inserted into the medium insertion port 3. Further, the stopper member 44b is advanced into the medium transport path 5 by the stopper driving portion 44a. When the insertion of the check S is detected in this standby state, the CPU 101 executes the processing of the check S as shown in FIG. When receiving a command for instructing processing of the roll paper R from the host computer 200 in the standby state, the CPU 101 executes the processing of the roll paper R as shown in FIG. When the CPU 101 detects that the check S is inserted from the medium discharge port 4 in the standby state, the CPU 101 executes validation printing as shown in FIG.

FIG. 5 is a flowchart showing the operation of the composite processing apparatus 1, and specifically shows the normal operation related to the check processing.
In the standby state, the CPU 101 waits for insertion of the check S from the medium insertion slot 3 (step S11). When the CPU 101 detects this check S based on the output value of the BOF sensor 41 input from the sensor drive circuit 109 (step S11; Yes), it controls the motor driver 113 to drive the roller opening / closing motor 39 to The 1st conveyance roller 34 and the 2nd conveyance roller 37 are moved to a closed position, and the check S is clamped by these 1st conveyance rollers 34 (step S12). In a state where the stopper member 44b has advanced into the medium conveyance path 5, the CPU 101 operates the slip conveyance motor 38 to rotationally drive the first conveyance roller 34, and performs the reciprocating conveyance of the check S a plurality of times (step S13). . By this operation, the check S is abutted against the stopper member 44b and the direction thereof is adjusted.

Here, the CPU 101 detects the presence or absence of the check S based on the output value of the BOF sensor 41 (step S14), and if the check S is not detected, it is determined that the check S has been pulled out or the process is terminated. To do.
On the other hand, when the check S is detected by the BOF sensor 41 (step S14; Yes), the CPU 101 drives the stopper driving unit 44a to retract the stopper member 44b from the medium conveyance path 5 (step S15). Subsequently, the CPU 101 transports the check S by the first transport roller 34, and reads the magnetic ink character of the check S based on the output value of the MICR head 42 during this time (step S16). When the printing on the back surface of the check S is instructed by the command received from the host computer 200, the CPU 101 conveys the slip conveyance motor 38 in the forward direction according to the printing position in the check S and conveys it downstream of the medium conveyance path 5. Alternatively, the check S is conveyed to the upstream side by reversing the slip conveyance motor 38 to convey the check S to the printing position (step S17), and printing is performed on the check S by the first print head 46 (step S18). ).

  When printing on the surface of the check S is instructed by the command received from the host computer 200, the CPU 101 conveys the check S to the printing position on the surface (step S19). The CPU 101 rotates the slip conveyance motor 38 in the forward direction in accordance with the printing position in the check S and conveys it to the downstream side of the medium conveyance path 5, or reverses the slip conveyance motor 38 and conveys the check S in the upstream side. When the check S reaches the printing position on the surface, the CPU 101 controls the head driving circuit 111 to print on the surface of the check S by the second print head 48 (step S20). After the printing on the front surface is finished, the CPU 101 drives the slip conveyance motor 38 and discharges the check S from the medium discharge port 4 by the second conveyance roller 37 (step S21).

  Here, the check S reaches a position protruding from the medium discharge port 4, but the rear end of the check S is inside the medium discharge port 4, and the presence of the check S is detected by the EJD sensor 49. The CPU 101 waits until the operator takes out the check S (step S22). When the CPU 101 detects that the check S is taken out and the detection value of the EJD sensor 49 is switched (step S23; Yes), the roller opening / closing motor 39 and the stopper are driven. The unit 44a is driven to return to the standby state (step S24). With the above operation, when the check S is inserted, the magnetic ink characters are read and printing on the front and back surfaces of the check S is performed.

FIG. 6 is a flowchart showing a normal operation related to roll paper printing.
When the CPU 101 receives a command for instructing printing on the roll paper R from the host computer 200 U (step S31), the CPU 101 starts the operation of FIG. 6, reads the received command from the reception buffer 104, and determines whether it is a print command. Is determined (step S32). Here, when the received command is a print command and print data is received following this command (step S32; Yes), the CPU 101 drives the roll paper transport motor 17 to transport the roll paper R, The thermal head 16 is energized to apply heat to the printing surface of the roll paper R to perform printing (step S33). When printing is completed, the roll paper R is conveyed until the printing end position of the roll paper R reaches the position of the auto cutter unit 21 (step S34), and the cutter drive motor 24 is driven to cut the roll paper R (step S35). ).
If the command received from the host computer 200 is not a print command, the CPU 101 operates the roll paper transport motor 17 to transport the roll paper R by a predetermined amount (step S36), and drives the cutter drive motor 24 to drive the roll paper R. Is cut (step S37).

FIG. 7 is a flowchart showing a normal operation related to validation printing.
The CPU 101 detects the insertion of the check S based on the change in the output value of the validation sensor 45 when the check S is inserted from the medium discharge port 4 in the standby state and the leading end reaches the recess 50 (step S41). ). The CPU 101 waits until a print command is received from the host computer 200 (step S42). When the print command is received from the host computer 200, the first print head 46 or the second print head 46 or the second print is sent to the check S according to the received command. Validation printing is performed by the print head 48 (step S43). After printing is completed, the CPU 101 stands by until the check S is removed by the operator. When the removal of the check S is detected based on changes in the output values of the validation sensor 45 and the EJD sensor 49, the CPU 101 returns to the standby state described above.

FIG. 8 is a diagram showing in detail the relationship between the A / D converter 108 included in the sensor drive circuit 109 and various sensors that input detection values to the A / D converter 108.
As shown in FIG. 8, the A / D converter 108 is provided with eight ports P0 to P7 as input ports.
On the other hand, as shown in FIG. 8, sensors for inputting a detection value to the A / D converter 108 include a BOF sensor 41, an EJB sensor 49, a validation sensor 45, a substrate temperature sensor 115, a power supply unit 120, a TOF sensor 43, There are eleven MOP sensors 47, a first print head temperature sensor 75, a second print head temperature sensor 76, a thermal head temperature sensor 77, and a MICR head 42.
That is, in this embodiment, the number of sensors that input detection values to the A / D converter 108 is larger than the number of ports of the A / D converter 108. This is due to the following reason.
That is, the composite processing apparatus 1 according to this embodiment was developed based on a receipt-issued thermal printer that has already been produced, with a policy of adding a check processing function to the thermal printer. The A / D converter 108 mounted on the composite processing apparatus 1 was not developed and produced as a dedicated A / D converter mounted on the composite processing apparatus 1, but mounted on the thermal printer. An A / D converter is used, thereby reducing production costs and improving manufacturability.
On the other hand, the composite processing apparatus 1 is provided with a mechanism and a device for performing various processes on the check S in addition to a mechanism and a device for performing printing processing on the roll paper R, and sensors are provided in association with the mechanism and the device. Because of the necessity, the number of sensors is larger than the number of sensors included in the thermal printer. For this reason, the number of sensors and the like that input detection values to the A / D converter 108 is larger than the number of ports of the A / D converter 108.
Such a situation can also occur when a general-purpose A / D converter that has already been mass-produced is used as the A / D converter 108.
In the present embodiment, the manufacturing cost increases in view of the fact that the number of sensors and the like that input detection values to the A / D converter 108 is larger than the number of ports of the A / D converter 108 as described above. The detection value of each sensor is appropriately input to the A / D converter 108 while suppressing this.
Hereinafter, the relationship between the A / D converter 108 and the sensors will be described in detail.

A first switching circuit 130 is mounted on the control board 40. The first switching circuit 130 is connected to the port P2 of the A / D converter 108, and the validation sensor 45 and the substrate temperature sensor 115 2 are connected. Two sensors are connected, and a detection value is input from both of these two sensors.
The first switching circuit 130 is a switch for switching a sensor that inputs a detection value to the A / D converter 108 to one of the validation sensor 45 and the substrate temperature sensor 115 under the control of the CPU 101. . The CPU 101 outputs a control signal from a predetermined port to the first switching circuit 130, thereby switching the sensor at a predetermined cycle.
As described above, in the present embodiment, both the validation sensor 45 and the substrate temperature sensor 115 are configured so that detection values can be input to one port P2 of the A / D converter 108, and the first switching is performed. The sensor is configured to switch the sensor for inputting the detection value to the A / D converter 108 at a predetermined cycle by the circuit, and thereby a plurality of (two) sensors can input the detection value to the A / D converter 108 together. While maintaining the state, one port is shared by the plurality of sensors, and the number of sensors that input detection values to the A / D converter 108 is more than the number of ports of the A / D converter 108. It corresponds to many situations.

Here, the validation sensor 45 detects that the tip of the check S has entered the recess 50 as described above. And it can be said that the validation sensor 45 does not require quickness, although certainty is calculated | required about the detection that the front-end | tip of the check S entered the recessed part 50. FIG. For example, when the user inserts the check S from the medium discharge port 4 to perform validation printing, the check S is detected to enter the recess 50 after a few seconds, and the user waits during that time. However, it can be said that there is no disadvantage to the user. Therefore, it can be said that the validation sensor 45 is a sensor that has no problem even if the detection cycle is longer than that of other sensors.
The substrate temperature sensor 115 is a sensor that is disposed on the back surface of the control board 40 where the motor driver 113 is mounted or in the vicinity of the motor driver 113 and detects the temperature of the control board 40. Here, since the temperature of the control board 40 does not rise or fall rapidly at a very short interval (for example, every 100 milliseconds), the substrate temperature sensor 115 has a longer detection cycle than other sensors. It can be said that it is a sensor with no problem.
As in the present embodiment, when the validation sensor 45 and the substrate temperature sensor 115 are configured to periodically switch the sensor that inputs a detection value to one port P2, the sensor is periodically switched. Thus, there will be a time zone in which the detection value is not input to the A / D converter 108 for each sensor. However, since the two sensors are sensors that do not have any problem even if the detection cycle is relatively long, It is possible to suppress adverse effects caused by the occurrence of the time zone.

Further, referring to FIG. 8, a second switching circuit 131 is mounted on the control board 40, and the second switching circuit 131 is connected to the port P <b> 6 of the A / D converter 108 and the first printing circuit. Three sensors, a head temperature sensor 75, a second print head temperature sensor 76, and a thermal head temperature sensor 77, are connected, and a detection value is input from these three sensors.
The second switching circuit 131 is a sensor that inputs a detection value to the A / D converter 108 under the control of the CPU 101, a first print head temperature sensor 75, a second print head temperature sensor 76, and a thermal head temperature sensor 77. It is a switch for switching to any one of the three sensors. The CPU 101 outputs the control signal from the predetermined port to the first switching circuit 130, thereby switching the sensor according to a predetermined condition.

Here, the composite processing apparatus 1 according to the present embodiment has a configuration in which the printing process for the check S by the slip printing unit 12 and the printing process for the roll paper R by the roll paper printing unit 13 cannot be performed simultaneously in parallel. ing. This is because a necessary voltage may not be ensured when the above two processes are performed in parallel due to the relationship with the output voltage of the power supply unit 120 mounted on the composite processing apparatus 1.
That is, in the present embodiment, the power supply unit 120 has a high output so that the printing process for the check S by the slip printing unit 12 and the printing process for the roll paper R by the roll paper printing unit 13 can be performed simultaneously. Rather than changing the power supply unit 120, the two printing processes are not performed in parallel, thereby suppressing an increase in the size of the power supply unit and an increase in manufacturing cost. Yes.
Further, in the present embodiment, as shown in FIG. 3, the first print head 46 and the second print head 48 are provided on the medium conveyance path 5 so as to be separated in the upstream-downstream direction. After printing on the back surface of the check S by the first print head 46, the check S is conveyed, and further, the second print head 48 performs printing on the surface of the check S. Due to such a configuration, printing on the back surface of the check S by the first print head 46 and printing on the surface of the check S by the second print head 48 are not performed simultaneously.
Thus, in the present embodiment, the thermal head 16, the first print head 46, and the second print head 48 are all configured so as not to be driven simultaneously with the other heads.
Here, the first print head temperature sensor 75 is a sensor provided to detect an abnormal increase in the temperature of the head when the first print head 46 is driven. Similarly, the second print head temperature sensor 76 is a sensor provided to detect an abnormal increase in the temperature of the head when the second print head 48 is driven, and the thermal head temperature sensor 77 is a thermal sensor. This is a sensor provided to detect an abnormal increase in the temperature of the head when the head 16 is driven. Therefore, the detected values of these sensors may be input to the A / D converter 108 when the corresponding head is driven. That is, each of these sensors has a different detection timing, and detects the temperature of the corresponding print head at a timing that corresponds to the time when the corresponding print head is driven.

Based on the above, in the present embodiment, the CPU 101 monitors which one of the thermal head 16, the first print head 46, and the second print head 48 is driven, and the second switching circuit 131. And controls the sensor that inputs the detected value to the port P6 of the A / D converter 108 among the first print head temperature sensor 75, the second print head temperature sensor 76, and the thermal head temperature sensor 77. Switch to the sensor corresponding to the head you are using. That is, the CPU 101 switches the sensor that inputs the detection value to the A / D converter 108 in accordance with the detection timing of each sensor (the timing according to which the corresponding print head is driven). As a result, it is possible to maintain a state in which a detection value of a necessary sensor is input to the A / D converter 108.
In other words, in the present embodiment, focusing on the fact that the three heads of the thermal head 16, the first print head 46, and the second print head 48 are driven exclusively, the sensors corresponding to these heads are provided as one sensor. A sensor group sharing a port is used, and a sensor corresponding to the head being driven is switched to a sensor that detects the one port.
In the above description, the CPU 101 functions as a switching unit that switches the sensor that inputs the detection value to the A / D converter 108 by controlling the first switching circuit or the second switching circuit.

As described above, the composite processing apparatus 1 according to the present embodiment includes the roll paper printing unit 13 that transports and records the roll paper R, the slip printing unit 12 that records on the check S, and the roll paper printing unit. A thermal head temperature sensor 77 that detects the temperature (state) of the 13 thermal heads 16, and a first print head that detects the temperatures (states) of the first print head 46 and the second print head 48 of the slip printing unit 12. A temperature sensor 75 and a second print head temperature sensor 76 are provided. Then, the detection value of any of these sensors can be input to one port P6 of the A / D converter 108, and the CPU functioning as a switching unit has a sensor for inputting the detection value to one port P6. Switch.
According to this, detection values of these sensors can be appropriately input to a signal processing circuit through one port, and the cost can be suppressed as compared with a case where an A / D converter having a large number of ports is newly provided. The detection value of each sensor can be input to a signal processing circuit.
In particular, in the present embodiment, the drive states of the thermal head 16, the first print head 46, and the second print head 48 are detected, and detection values are input to one port P6 according to the drive states of these heads. Switch the sensor. More specifically, among these heads that are driven exclusively, sensors corresponding to the heads that are driven (the thermal head temperature sensor 77, the first print head temperature sensor 75, and the second print head temperature sensor 76). Either) is a sensor that inputs a detection value to the port P6.
According to this, the detection value of the sensor corresponding to the driving head can be input to the A / D converter 108, and the required detection value of the sensor can be input to the A / D converter 108.
In particular, since the above effect can be obtained without providing the A / D converter 108 with many ports, the manufacturing cost can be suppressed.

In this embodiment, the thermal head temperature sensor 77, the first print head temperature sensor 75, and the second print head temperature sensor 76 are connected to one port P6 so that the detected values can be input. Each of these sensors is a sensor having a different detection timing, and detects the temperature of the corresponding print head at a timing corresponding to the time when the corresponding print head is driven. Then, the CPU 101 switches the sensor that inputs the detection value to the A / D converter 108 in accordance with the detection timing of each sensor (the timing according to which the corresponding print head is driven).
As a result, it is possible to maintain a state in which a detection value of a necessary sensor is input to the A / D converter 108.

In the present embodiment, the detection values of a plurality of sensors having a detection cycle longer than that of other sensors, that is, the validation sensor 45 and the substrate temperature sensor 115, are detected for the port P2 of the A / D converter 108. The CPU 101 functioning as a switching unit that can be input switches the sensor that periodically inputs the detection value to the A / D converter 108.
Here, as in this embodiment, when the sensor for inputting the detection value to one port P2 is periodically switched for the validation sensor 45 and the substrate temperature sensor 115, the sensor is periodically switched. Along with this, there will be a time zone in which the detection value is not input to the A / D converter 108 for each sensor, but both sensors are sensors that do not have a problem even if the detection cycle is relatively long. An adverse effect due to the occurrence of the above time period can be suppressed.

  Next, another embodiment will be described.

FIG. 9 is a diagram illustrating a relationship between the first switching circuit 130 and a sensor connected to the first switching circuit 130 in another embodiment.
Here, the MOP sensor 47 is a sensor that detects the presence or absence of the check S that is transported through the medium transport path 5, the BOF sensor 41 that detects the trailing edge of the check S, and the check inserted from the medium insertion slot 3. It is a sensor that plays an auxiliary role of the TOF sensor 43 that detects the tip of S. Therefore, it can be said that the detection cycle may be longer than that of the BOF sensor 41 and the TOF sensor 43.
Based on this, referring to FIG. 9A, the validation sensor 45 and the MOP sensor 47 may be connected to the first switching circuit 130, and these sensors may be switched under the control of the CPU 101. Even in this configuration, a sensor having a detection cycle longer than that of other sensors is connected to the first switching circuit 130, and the same effects as those of the first embodiment described above can be obtained.
9B, the substrate temperature sensor 115 and the MOP sensor 47 may be connected to the first switching circuit 130, and these sensors may be switched under the control of the CPU 101. Even in this configuration, a sensor having a detection cycle longer than that of other sensors is connected to the first switching circuit 130, and the same effects as those of the first embodiment described above can be obtained.
