Description

  The present invention relates to an electronic device capable of executing processing using different command systems by a plurality of processing units, and an electronic device control method.

  Conventionally, there are various types of electronic devices such as a printer connected to a host computer such as a personal computer. Usually, control commands for controlling the electronic devices by the host computer differ depending on the model. As an electronic apparatus of this type, for example, as shown in Patent Document 1, a command system for normal operation and a command system emulating a command system of another device are different for a printing unit, an optical reading unit, and the like. What is made executable in the processing unit is known.

JP 2012-59165 A

  Generally, in different command systems, the relative position management with respect to the transport path when transporting the recording medium is also different. For this reason, in the electronic device disclosed in Patent Document 1, after printing processing is performed on a recording medium using an emulation command system that emulates the command system of another device, an image corresponding to the recording medium is displayed using a command system for normal operation. In order to initialize the relative position management, it is necessary to eject the recording medium when the command system is switched. That is, in the electronic device of Patent Document 1, after performing the printing process using the emulation command system, the image scanning process can be performed only after the recording medium is ejected. As a result, refeeding work by the operator is interposed between the printing process and the image scanning process, leading to a reduction in work efficiency.

  The present invention has been made in view of such circumstances, and even when an electronic device capable of executing processing using a different command system by a plurality of processing units is used by switching the command system, the work efficiency is improved. The purpose is to provide technology that does not decrease

  In order to solve at least a part of the above problems, the present invention can be realized as the following application examples.

An electronic device according to one embodiment of the present invention includes:
A transport unit that transports the processing medium along the transport path;
A printing unit that performs printing on the processing medium conveyed along the conveyance path;
An image reading unit that reads an image from the processing medium conveyed along the conveyance path;
Based on the received command, a command system for printing control and a command system for image reading control are switched to control the printing unit and the image reading unit, and the discharge unit that controls the transport unit to discharge the processing medium. A control unit for performing processing;
With
The control unit performs the discharge processing when the command system is switched from the command system for image reading control to the command system for printing control, and the command system for image reading control from the command system for printing control. When switching the command system, the discharge process is omitted.

  According to the above configuration, the processing medium discharge process does not occur when performing the image reading process in which the management of the relative position of the processing medium with respect to the conveyance path is not important by switching the command system.

  In this case, at least one of the command system for print control and the command system for image reading control may be an emulation command system that emulates another command system.

Further, in the discharging process, when it is determined that there is the processing medium on the transport path and the first process for detecting the presence or absence of the processing medium on the transport path, the transport unit is controlled to And a second process for discharging the processing medium from the conveyance path.
According to such a configuration, when the processing medium is already discharged from the conveyance path, the processing medium discharge processing can be omitted.

According to another aspect of the present invention, there is provided a control method for an electronic device, which is one of printing processing and image reading processing based on a first command system for a processing medium transported along a transport path inside the electronic device. A first step of performing
A second step of switching the command system from the first command system to the second command system and initializing a relative position of the processing medium with respect to the transport path based on a predetermined condition;
A third step of performing the other of the printing process and the image reading process on the processing medium based on the second command system,
The initialization of the relative position in the second step is executed when the printing process is performed based on the second command system, and when the image reading process is performed based on the second command system. It is omitted.

  According to the above configuration, even when the first command system and the second command system are switched, when the image reading process is performed based on the second command system, the initial position of the relative position of the processing medium relative to the conveyance path is determined. Therefore, the image reading process can be performed continuously from the printing process without the discharge process or the rearrangement process of the processing medium.

  In addition, when printing processing is performed based on the second command system, it is preferable to perform processing medium discharge processing or alignment processing, which can prevent poor management of the relative position of the processing media. .

Serial interface (I / F) that converts the data format when transmitting and receiving information to and from the FLASH-ROM 42 that stores control programs executed by the computer, data to be processed, and the host computer 200 that controls the multifunction device 10 43 and a USB interface 44, a gate array (G / A) 45 connected to various sensors, a motor driver 46 for driving various motors, and a head driver 48 for driving a head. Connected through. The RAM 41 functions as a buffer memory such as a reception buffer that temporarily stores various commands transmitted from the host computer 200 and an image buffer that temporarily stores read image data read by the image reading unit 110.

  An alignment sensor 39, a medium edge sensor 47, a medium width sensor 55, a first scanner module 111, and a second scanner module 112 are connected to the gate array 45. The gate array 45 quantizes the analog voltage input from the alignment sensor 39, the medium edge sensor 47, and the medium width sensor 55 into digital data, and outputs the digital data to the CPU 40.

The motor driver 46 is connected to the medium transport motor 26, the carriage drive motor 56, and the alignment motor 58, and supplies these motors with drive current and drive pulses to operate these motors. Based on the output from the transport unit 100 such as the medium transport motor 26 and the output from the medium end sensor 47, the CPU 40 internally holds the relative position of the processing medium S with respect to the transport path P as a calculated value. The position on the conveyance path P can be grasped.
The head driver 48 is connected to the recording head 18 and causes the recording wire to protrude by supplying a driving current to the recording head 18.

FIG. 5 is a block diagram illustrating functional configurations of the multifunction machine 10 and the host computer 200.
The host computer 200 implements each unit shown in FIG. 5 by executing various programs by a CPU (not shown). That is, the host computer 200 provides an application program 201, a scanner driver 211 and a printer driver 217 that provide functional modules for controlling the multifunction peripheral 10 to the application program 201, and a scanner driver 211 and a printer driver 217. And a port handler 221 for assigning input / output ports provided in the host computer 200. The host computer 200 inputs / outputs various data and control signals to / from the multifunction machine 10 via the USB port 231, the serial port 233, and the parallel port 235 under the control of the port handler 221.

  The multifunction machine 10 includes a reception buffer 66 that temporarily stores commands and data transmitted from the host computer 200 via the serial interface 43 and the USB interface 44. The multi-function device 10 includes a control unit 70 that executes commands stored in the reception buffer 66. This control part 70 is implement | achieved by running a control program by CPU40 (FIG. 4).

The control unit 70 can switch and execute each operation mode of the printer control mode 71, the printer control mode 72, and the scanner control mode 75.
The printer control mode 71 and the printer control mode 72 are operation modes in which printing is performed on a passbook as the processing medium S by the recording head 18. In the printer control modes 71 and 72, the processing medium S is conveyed and aligned as necessary, and characters, symbols, and the like are printed on the processing medium S. The scanner control mode 75 is an operation mode in which the image reading unit 110 performs optical image reading of the processing medium S.

  The command transmitted from the host computer 200 to the multi-function device 10 is a command defined by a predetermined command system. The scanner driver 211 and the printer driver 217 each correspond to a specific command system, and the host computer 200 transmits a command defined in the specific command system to the multifunction device 10.

Each operation mode of the control unit 70 corresponds to a different command system (command group). The printer control mode 71 is a normal operation mode for operating according to commands of the command system V provided for the multifunction machine 10 of the present embodiment.
The printer control mode 72 is an operation mode for operating in accordance with commands of a command system W that is a command system provided for devices other than the multifunction machine 10 (here, the printer W). That is, the printer control mode 72 is an emulation operation mode for emulating the operation of the printer W and causing the multifunction peripheral 10 to operate according to the same command as the printer W.
The scanner control mode 75 is a normal operation mode for operating in accordance with commands in the command system L that is a command system provided for the multifunction machine 10.

  In a system in which the printer W is connected to the host computer 200 and used, when the printer W is replaced with the multifunction device 10, the printer driver 217 of the host computer 200 is normally replaced with a device driver suitable for the multifunction device 10. There is a need. However, since the multifunction machine 10 has the printer control mode 72 that is an operation mode for emulation, the host computer 200 uses the printer driver 217 for the printer W by executing the printer control mode 72. It is possible to continue and avoid the work burden associated with the replacement of the device driver. Furthermore, the system trouble of the host computer 200 due to the replacement of the device driver can be avoided.

  The command system W in the printer control mode 72 corresponds to a command system for emulation, and the command system V in the printer control mode 71 corresponds to a command system for normal operation. Note that the multifunction device 10 of the present embodiment can be provided with a large number of emulation printer control modes in the multifunction device 10 in order to enable more types of emulation.

The command system V corresponding to the printer control mode 71 and the command system W corresponding to the printer control mode 72 include commands for instructing switching to another operation mode. For example, the control unit 70 that has received this command can shift from the printer control mode 71 or the printer control mode 72 to the scanner control mode 75.
In the present embodiment, the command system V corresponding to the printer control mode 71 or the command system W corresponding to the printer control mode 72 includes a reading start command necessary for scanner control. For this reason, when the MFP 10 operates as a printer in the printer control mode 72 corresponding to the command system W for other devices and then receives a reading start command in the image reading unit 110, the scanner control is performed from the printer control mode 72. Shifting to mode 75, reading by the image reading unit 110 is started.

FIG. 6 is a flowchart illustrating an example of the operation of the multifunction machine 10.
The operation illustrated in FIG. 6 is such that when a passbook is inserted as the processing medium S from the manual feed slot 15, the multifunction machine 10 is operated according to the emulation command system W for other devices, and this passbook is printed. After the command system is switched and the information displayed in the passbook is read according to the normal operation command system L for the multifunction machine 10, the command system is returned to the command system V or the command system W for printing. It is a series of operations.

  First, in step S11, the control unit 70 of the MFP 10 is activated in the printer control mode 72 according to the emulation command system W for other devices, and detects that the bankbook has been inserted into the manual feed slot 15. Detection is based on 47 detection values. Next, in step S12, the control unit 70 controls the motor driver 46 to operate the alignment motor 58 to advance the alignment plate 38 into the transport path P, and operates the medium transport motor 26 to change the direction of the passbook. Alignment processing is performed.

  Next, in step S <b> 13, the control unit 70 controls the motor driver 46 to drive the medium transport motor 26 to transport the bankbook to the print start position of the recording head 18. Thereafter, in step S14, the control unit 70 drives the medium transport motor 26 and the carriage drive motor 56, controls the head driver 48 to execute the printing process by the recording head 18, and every time one line of printing is completed. Carry a pass through the bankbook. When this series of printing processes is finished, in step S15, the control unit 70 drives the medium carrying motor 26 to carry the bankbook to the printing end position.

  Next, in step S16, the control unit 70 switches the command system from the command system W for printing to the command system L for image reading. The detailed flow when switching the command system will be described later.

  When the switching of the command system is completed, in step S17, the control unit 70 controls the motor driver 46 to operate the medium transport motor 26 to transport the bankbook to the scan start position. Thereafter, in step S18, the control unit 70 operates the medium transport motor 26, acquires output data of the first scanner module 111 and the second scanner module 112 via the gate array 45, and executes scanning. In step S19, the control unit 70 analyzes the acquired output data of the first scanner module 111 and the second scanner module 112 to acquire both-side read images of the passbook, and recognizes OCR (Optical Character Reader) recognition. Do.

  Finally, in step S20, the control unit 70 switches the command system from the command system L for image reading to the command system V for printing or the command system W, and in step S21, starts printing the passbook on the recording head 18. Then, the process is finished.

FIG. 7 is a flowchart showing a flow when the command system of step S16 or step S21 in FIG. 6 is switched.
When switching the command system in step S16 or step S21, first, the control unit 70 determines whether the current command system is the command system W for printing or the command system L for scanning (step S30).

  Here, when the current command system is the command system W for printing, the control unit 70 switches the command system from the command system W for printing to the command system L for scanning (step S33), and ends the command system switching. To do. As described above, the image reading unit 110 independently manages the vertical position of the bankbook by the position management unit, and this vertical position is relative to the conveyance path P of the bankbook obtained from the alignment sensor 39 and the medium edge sensor 47. It is separate from the relative position. Therefore, even when the command system is switched from the command system W for the other device to the command system L for the own device, it is not necessary to discharge the passbook and reset the vertical position management of the passbook. Transition to image reading processing can be performed continuously.

If the current command system is the scan command system L, the control unit 70 determines whether or not there is a bankbook in the transport path P (step S31).
When it is determined that there is no bankbook in the transport path P (No in step S31), that is, when the bankbook has already been discharged due to circumstances such as a discharge command included in the scan command system L, The control unit 70 switches the command system from the scan command system L to the print command system W (step S33), and ends the command system switching.

On the other hand, when it is determined that there is a bankbook in the transport path P (Yes in step S31), the control unit 70 drives the medium transport motor 26 to discharge the bankbook from the manual feed port 15 or the discharge port 20 (step S32). ), The relative position of the processing medium S with respect to the transport path P is initialized based on a predetermined condition. Thereafter, the control unit 70 switches the command system from the scan command system L to the print command system W (step S33), and ends the command system switching. When the command system is switched from the command system L for image reading control to the command system W for printing control, it is necessary to reset the vertical position management of the bankbook before the start of the printing process. Become.
In step S32, the control unit 70 discharges the passbook from the manual feed port 15 or the discharge port 20. Alternatively, the passbook may be conveyed to the alignment position and subjected to the alignment process by the alignment unit 28. Good.

As described above, in the present embodiment, when the control unit 70 switches the command system from the command system L for image reading control to the command system W for printing control, the passbook discharging process, that is, the conveyance of the processing medium S is performed. When the relative position with respect to the path P is initialized and the command system is switched from the command system W for printing control to the command system L for image reading control, the passbook discharging process is omitted. With such a configuration, even when the command system W for printing control and the command system L for image reading control are switched, the image is not accompanied by initialization of the relative position by discharging the processing medium S after the printing process. Reading processing can be performed continuously.
That is, in the image reading process, unlike the printing process in which the control of the printing position is important, the relative position management between the transport path P and the processing medium S is not important, and it is a problem if the relative position in the read image can be grasped. Absent. Accordingly, it is possible to perform vertical position management that is separate from the printing process without using the output from the medium edge sensor 47 or the like. This embodiment uses this, and even if the image reading process is performed after the printing process, it is not necessary to initialize the deviation between the processing medium S and the held value in the CPU 40. In addition, the process of once discharging the processing medium S from the transport path P is omitted. For this reason, when the printing process and the image reading process are continuously performed, the refeeding operation of the processing medium S by the operator is not necessary, so that the working efficiency can be improved as compared with the conventional case.

  Furthermore, when the control unit 70 detects the presence or absence of the processing medium S on the transport path P and determines that the processing medium S is on the transport path P, the control unit 70 controls the transport unit 100 to transport the processing medium S. Emission from P is performed. With such a configuration, even when the command system is switched from the command system L for image reading control to the command system W for printing control, if the processing medium S does not exist on the conveyance path P, the processing medium S The discharge process can be omitted, and the processing efficiency can be improved.

  Even when the printing process is performed subsequent to the image reading process, the posture and the position with respect to the conveyance path P may be simply rearranged without discharging the processing medium S from the conveyance path P. As a result, even when the vertical position management of the processing medium S needs to be reset, it is not necessary to refeed the processing medium S by the operator, and thus workability can be improved.

  Although one embodiment of the present invention has been described above, the present invention is not limited to the above-described embodiment, and other configurations can be adopted as necessary without departing from the spirit of the present invention.

  In the above embodiment, the CPU 40 mounted on the control board (not shown) mounted on the multifunction device 10 has the function shown in the functional block of FIG. 4 and controls each part of the multifunction device 10 as an example. As described above, for example, a device externally connected to the multifunction device 10 may function as part or all of the functional units illustrated in FIG. 4 to control the multifunction device 10. Furthermore, each functional block shown in FIG. 4 is realized by cooperation between hardware and software, and a specific hardware implementation form, software specifications, etc. are arbitrary, and other details. The configuration can be arbitrarily changed.

  In the above-described embodiment, the MFP 10 including the SIDM recording head 18 and the image reading unit 110 has been described as an example.
