Description

  The present invention relates to an auto cutter device having an error recovery processing function, a printer device, and a control method for the auto cutter device.

  2. Description of the Related Art Conventionally, a printing system that executes a factor canceling process by a host device in response to an error factor that has occurred in a printer device is known (for example, Patent Document 1). The host device determines an abnormality factor of the printer device based on the error occurrence information transmitted from the printer device, and transmits an error recovery command corresponding to the determined abnormality factor to the printer device.

  By the way, many printer apparatuses have an auto cutter mechanism for cutting long paper (roll paper). When an error occurs in the auto cutter mechanism, it is common to perform error recovery by transmitting an error recovery command from the host device or opening / closing the roll paper cover as in Patent Document 1 described above. However, depending on the structure and arrangement of the auto cutter mechanism and the roll paper cover, when an auto cutter error occurs, the cutter blade may remain protruding and the roll paper cover cannot be opened. For this reason, only the error canceling method using the error recovery command is currently available.

JP 2007-18127 A

  However, when an auto cutter error occurs, operations on the printer device side such as checking the state of the cutter blade and removing the paper that failed to cut the paper are required. Further, when the cutter position of the cutter blade is not appropriate, an operation for returning the cutter blade to the initial setting position (home position) is also necessary. As described above, conventionally, when an auto cutter error occurs, both the operation on the printer device side and the operation on the host device side (error transmission command transmission instruction) must be performed, which is troublesome.

  In view of the above problems, an object of the present invention is to provide an auto cutter device, a printer device, and a control method for an auto cutter device that can easily and quickly recover from an error when an auto cutter error occurs. .

  An auto cutter device according to the present invention faces a paper conveyance path, cuts a paper, a paper cutting unit, an internal state determination unit for determining an internal state of the auto cutter device, one operation unit, and an operation of one operation unit Accordingly, when the internal state is an error occurrence state of the paper cutting unit, the processing execution unit of the paper cutting unit is operated according to the operation of one operation unit. An error recovery process including an initialization process is executed, and when the internal state is a normal state, a predetermined process is executed in advance.

  A control method for an auto cutter device according to the present invention is a control method for an auto cutter device that includes a paper cutting unit that faces a paper transport path and cuts the paper, and one operation unit. An internal state determination step for determining a state, and a process execution step for executing processing according to the internal state in accordance with an operation of one operation unit. The process execution unit generates an error when the internal state is a paper cutting unit. In the case of a state, an error recovery process including an initialization process of a paper cutting unit is executed according to an operation of one operation unit, and when the internal state is a normal state, a predetermined process is executed in advance. To do.

According to these configurations, when the internal state of the auto cutter device is an error occurrence state of the paper cutting unit, the error recovery process is executed according to the operation of one operation unit. Error recovery can be performed without requiring any operation on the device side. In addition, since the error recovery process includes an initialization process for the paper cutting unit, an operation for performing the initialization process is not necessary, and the user's labor can be further reduced. In addition, when the internal state is the normal state, the one operation unit is for executing a predetermined process, and thus it is not necessary to add a dedicated operation unit to realize the present invention. . That is, the error recovery processing function can be mounted on the auto cutter device without significantly increasing the device cost.
The “normal state” refers to a state in which no error (including various errors in addition to the paper cutting unit error) has occurred.

  In the above auto cutter device, the paper cutting unit includes a fixed blade, a movable blade that performs a cutting operation on the fixed blade, and a cutter motor that drives the movable blade. It is a process for returning the movable blade to the initial setting position by driving the motor in a direction opposite to the driving direction at the time of the cutting operation.

  According to this configuration, when a paper cutting unit error (auto cutter error) occurs and the movable blade remains protruding, and the roll paper cover cannot be opened, the cutter motor is rotated in the reverse direction. With such simple control, the movable blade can be returned to the initial setting position.

  According to another aspect of the present invention, there is provided a printer apparatus comprising: the above-described auto cutter apparatus; and a printing unit that faces a sheet conveyance path and performs printing on a sheet.

According to this configuration, it is possible to provide a printer device that can easily and quickly recover from an error when an auto cutter error occurs.
In addition, the printing method of a printing part does not ask | require the kind, such as a thermal head system and an inkjet system.

  The above-described printer device further includes a table storing error recovery processing for each error type, the internal state determination unit determines the error type, the process execution unit refers to the table, and one operation unit According to the above operation, error recovery processing corresponding to the type of error is executed.

According to this configuration, it is possible to execute not only the auto cutter error but also error recovery processing corresponding to various types of errors occurring in the printer device only by an operation on the printer device side.
Examples of error types and corresponding error recovery processing include initialization processing of the paper cutting section when an auto cutter error occurs, and roll paper cover closing processing when the roll paper cover is open (the automatic opening and closing function is And a head cooling process (such as driving a cooling fan) at the time of high print head sound.

  In the printer apparatus described above, an error display unit is further provided that performs different display depending on the type of error when the internal state is determined to be an error occurrence state by the internal state determination unit.

According to this configuration, it is possible for the user to check what kind of error has occurred in the printer device by displaying the error display unit.
Note that the error display unit may notify information by lighting / flashing such as an LED, or may notify information by an image or a character such as a liquid crystal display.
Moreover, it is preferable that an error display part does not display LED, or displays that on a liquid crystal display, when an error factor is eliminated. For example, if an auto cutter error has occurred and the auto cutter error has been resolved by operating the operation unit 1, the LED is not displayed and the initialization process cannot be executed due to a paper jam or the like. If the LED cannot be resolved, it is preferable to keep the LED in the display state.

  In the above printer apparatus, the process execution unit is configured to carry a predetermined amount of paper as the predetermined process.

  According to this configuration, a paper feed (paper feed) switch can be applied as one operation unit. Thus, paper jams can be prevented by operating one operation unit to feed paper, such as when no error has occurred (normal state) and the leading edge of the paper has not come out of the paper discharge port. .

  The control panel 84 includes a paper feed switch (hereinafter, referred to as “PF-switch”) 83 in addition to the power LED 85, the error LED 86, and the no-paper LED 87. The power LED 85 indicates power ON / OFF by turning on / off. The error LED 86 indicates the type of error by lighting or blinking when an error occurs (when the printer 100 cannot print). Further, the no-paper LED 87 is lit when the roll paper 11 runs out or when the remaining amount is low. Further, the PF-switch 83 feeds the roll paper 11 by one line each time it is pressed in the normal state. Further, by continuously pressing the PF-switch 83, it is possible to continuously feed the paper. Note that when the PF-switch 83 is operated in an error occurrence state, the printer device 100 executes error recovery processing according to the error type. Details will be described later.

  The roll paper cover 21 is provided with a platen roller 19 that is a rotating member for transporting the roll paper 11 and a cover frame 23. Bearing portions 27 are formed at both ends of the rear portion of the cover frame 23, and the bearing portions 27 are supported by the main body frame 15 via a support shaft 29 so as to be freely opened and closed. Inside the printer main body 13, a roll paper holder 31 (roll paper storage unit) capable of storing the roll paper 11 is provided, and a thermal head 33 is provided in front of the roll paper holder 31. The platen roller 19 is arranged to face the thermal head 33 in a state where the roll paper cover 21 is closed, and sandwiches the roll paper 11 to be sent out. Printing is performed by driving the thermal head 33 in this state. The platen roller 19 is provided on a platen holder 39 of the platen unit 37, and the platen holder 39 has a release lever mechanism 22. The release lever mechanism 22 includes an engagement claw and a release lever that can be interlocked with the engagement claw, and constitutes a lock mechanism that closes the roll paper cover 21 with respect to the main body case 17. In addition, the printer apparatus 100 includes a cover sensor 70 that detects opening / closing of the roll paper cover 21 and a paper sensor 133 (see FIG. 4) provided on the side wall in the roll paper holder 31.

  The roll paper cover 21 includes a fixed blade 41 that is a cutter for cutting the roll paper 11 in the vicinity of the paper discharge port 25. On the other hand, a cutter unit 45 incorporating a movable blade 43 is provided at the front of the printer main body 13. The fixed blade 41 and the movable blade 43 face each other with the roll paper cover 21 closed, and constitute a scissor-type cutting mechanism. A movable blade 43 is provided on the bottom 42 of the main body 45b of the cutter unit 45, and the movable blade 43 is in the direction of arrow A shown in FIG. Or it is attached so that rotation to the opposite direction is possible. The movable blade 43 is pressed against the bottom 42 of the main body 45 b of the cutter unit 45 by a coil spring 46 that is locked by a push nut attached to the support shaft 44. A long hole 48 for driving the movable blade 43 is provided in a substantially central portion of the movable blade 43.

  A driving unit 50 for driving the movable blade 43 is provided on the back surface of the cover 45 a of the cutter unit 45. That is, the cutter motor 52 is attached to the back surface of the cover 45 a, and the worm gear 51 and the motor knob 91 are attached to the rotating shaft of the cutter motor 52. The motor knob 91 is used for manually rotating the cutter motor 52 reversely (see FIG. 6). On the other hand, the worm gear 51 meshes with the worm wheel 53, and the worm wheel 53 is provided with a crank pin 55 that engages with the long hole 48 of the movable blade 43. Further, a cutter sensor 57 for detecting the rotation angle of the worm wheel 53 is provided between the worm wheel 53 and the cover 45a, and this cutter sensor 57 is connected to the circuit board 60 via a lead wire 59. . The cutter motor 52 is also connected to the circuit board 60 via the lead wire 54. Thereby, the cutter motor 52 is rotated based on the rotation angle of the worm wheel 53 detected by the cutter sensor 57.

  Next, the control configuration of the printer apparatus 100 will be described with reference to FIG. The printer apparatus 100 includes an interface unit 110, a paper transport unit 120, a detection unit 130, a printing unit 140, a paper cutting unit 150, an operation unit 160, a display unit 170, and a control unit 180.

  The interface unit 110 inputs and outputs information to and from the host device 200. The paper transport unit 120 includes a platen roller 19 and a roller drive motor (not shown), and transports the roll paper 11.

  The detection unit 130 includes the above-described cutter sensor 57 (sensor that detects the rotation angle of the worm wheel 53), paper sensor 133 (sensor that detects that there is no paper or the remaining amount of paper is low), and a cover sensor 70 (roll paper). In addition to a sensor for detecting the opening and closing of the cover 21, a head sensor 131 and a home position sensor 132 are provided. The head sensor 131 is a sensor that detects the temperature of the thermal head 33. The home position sensor 132 is a sensor that detects that the movable blade 43 is at the home position (initial setting position). The printer device 100 measures the time to return to the home position after cutting the paper by the movable blade 43. If the movable blade 43 does not return to the home position within the specified time, “auto cutter error (error occurrence state of the paper cutting unit 150) ) ”. Possible causes include deterioration of the cutter unit 45, biting of the movable blade 43, paper jam (paper jam), contamination of the movable region of the movable blade 43 (mixing of insect pins, clips, etc.), and the like.

  The printing unit 140 includes a thermal head 33 and performs printing on the roll paper 11 by selectively applying energy to a plurality of heating elements of the thermal head 33. The paper cutting unit 150 includes the above-described fixed blade 41, the movable blade 43 included in the cutter unit 45, and the cutter motor 52, and cuts the roll paper 11 using a scissor method.

  The operation unit 160 includes the PF-switch 83 described above. As the PF-switch 83, various switches and buttons such as a non-locking push switch can be adopted. Further, in a normal state where no error has occurred, a predetermined amount of paper is fed by pressing the PF-switch 83. Note that the length of the predetermined amount can be varied by a line feed amount designation command transmitted from the host device 200. If the PF-switch 83 is pressed while waiting for execution by the macro execution command transmitted from the host device 200, the defined macro is executed. Furthermore, when the self-test is executed, the function is a pause and resume function. The self test is executed by turning on the power while pressing the PF-switch 83 with the roll paper cover 21 closed.

  The display unit 170 includes the power LED 85, the error LED 86, and the no-paper LED 87 described above. The error LED 86 is turned on immediately after the power is turned on or immediately after the reset (offline state), but automatically turns off after a few seconds (when the printer device 100 is ready to print). In the normal state (online), the light is turned off. Further, the no-paper LED 87 blinks when waiting for the self-test to continue or waiting for a macro execution instruction.

  The control unit 180 includes a CPU (Central Processing Unit) 181, a ROM (Read Only Memory) 182, a RAM (Random Access Memory) 183, and a timer 184. The timer 184 measures the time for the movable blade 43 to return to the home position after cutting the paper.

  The ROM 182 stores a table T as part of the control data. As shown in FIG. 5, the table T stores the lighting / flashing pattern of the error LED 86 or the paper LED 87 and error recovery processing for each type of error. All of the error recovery processes shown in the figure are executed when the PF-switch 83 is pressed with the roll paper cover 21 closed. Further, as shown in the figure, each LED 86, 87 has a different lighting / flashing pattern defined according to the type of error.

  The error types are roughly classified into recoverable errors and non-recoverable errors. An “auto cutter error” and a “head high temperature error (error detected by the head sensor 131)” shown in the same figure are types of recoverable errors, and an error recovery process corresponding to each error type is executed. Although not specifically illustrated, an “paper out error” detected by the paper sensor 133 and a “roll paper cover open error” detected by the cover sensor 70 are error recovery processing corresponding to the occurrence of an error as a recoverable error. May be performed. Further, in the case of a printer device that detects the black mark position of paper with a black mark, when a black mark detection error occurs, a corresponding error recovery process may be performed as a recoverable error.

  A “CPU execution error” shown in FIG. 5 is an error when the CPU 181 executes an illegal address, and is a kind of unrecoverable error. In the case of an unrecoverable error, a special error recovery process is not executed, and the board unit is replaced based on the user's judgment. In addition, although not particularly illustrated, “read / write error” that occurs when reading / writing of the RAM 183 cannot be performed normally, “high / low voltage error” that occurs when the power supply voltage is high or low, and internal circuit connection An “internal circuit connection error” or the like that occurs when it is not normal is also included in the unrecoverable error.

  On the other hand, the CPU 181 functions as a main part of the “internal state determination unit” and the “processing execution unit”. The “internal state determination unit” determines the internal state of the printer device 100 based on the detection result of the detection unit 130. In the error occurrence state, the type of error is determined. On the other hand, the “process execution unit” executes the process according to the internal state in accordance with the operation of the PF-switch 83. Specifically, when the internal state is the normal state, a paper feed process (predetermined predetermined process) is executed in accordance with depression of the PF-switch 83. When the internal state is a “head high temperature error” occurrence state, error recovery processing including head cooling processing of the thermal head 33 is executed as shown in the table T of FIG. As the head cooling process, forced cooling by driving a cooling fan (not shown) may be performed, or the thermal head 33 may be naturally cooled by leaving it in a print disabled state for a predetermined time.

  Further, when the internal state is an “auto cutter error” occurrence state, the “process execution unit” executes error recovery processing including initialization processing of the paper cutting unit 150 according to the operation of the PF-switch 83. The “initializing process of the paper cutting unit 150” includes a process of driving the cutter motor 52 in the direction opposite to the driving direction during the cutting operation (during normal operation). Thereby, the movable blade 43 rotates in the direction opposite to the arrow A direction in FIG. 3 and returns to the home position. When the home position sensor 132 detects that the movable blade 43 has returned to the home position, the CPU 181 turns off the error LED 86. As described above, when an “auto cutter error” occurs, the error recovery process including the initialization process of the paper cutting unit 150 is performed simply by pressing the PF-switch 83, so the movable blade 43 is brought to the home position. There is no need for a return operation or an operation for transmitting an error recovery command from the host device 200. Even when a paper jam has occurred, the movable blade 43 is returned to the home position by the initialization process, so that the roll paper cover 21 is not opened, and the roll paper 11 is removed by removing the paper. By setting and closing the roll paper cover 21, the printable state can be obtained.

  However, there may be a case where it is difficult to cancel the error even if the PF-switch 83 is pressed due to the degree of paper jamming or foreign matter contamination. In this case, as shown in FIG. 6, the cutter cover 35 is pulled forward, and the motor knob 91 is operated from the notch 92 formed in the cover 45 a of the cutter unit 45. A caution seal 94 is affixed to the left of the notch 92, and the user rotates the motor knob 91 in the direction of arrow B until a triangular mark is seen in the round hole 93 according to the instruction of the caution seal 94. Let When the motor knob 91 does not rotate in the arrow B direction, the motor knob 91 is once turned in the opposite direction, and the PF-switch 83 is pressed while the motor knob 91 is loosened. By repeating this several times, the auto cutter error can be resolved almost certainly.

  Next, the operation of the printer apparatus 100 when the PF-switch 83 is pressed will be described with reference to the flowchart of FIG. When the user presses the PF-switch 83 (S01), the printer apparatus 100 (CPU 181) determines the internal state (S02). If the printer device 100 (CPU 181) determines the normal state, the platen roller 19 is driven to perform the paper conveyance process. Is executed (S03). If it is determined that the internal state is an auto cutter error occurrence state, error recovery processing including initialization processing of the paper cutting unit 150 is executed (S04). If the internal state is determined to be a head high temperature error occurrence state, error recovery processing including head cooling processing is executed (S05). If it is determined that the internal state is another recoverable error occurrence state (however, it is limited to an error for which error recovery processing is defined), error recovery processing corresponding to the type of error is executed (S06). . Further, if it is determined that an unrecoverable error has occurred, the special error recovery process is not executed and the operation is terminated.

  As described above, according to the present embodiment, error recovery processing corresponding to various types of errors that occur in the printer apparatus 100 can be performed on the printer apparatus 100 side without requiring operation of the host apparatus 200 ( It can be easily executed only by pressing the PF-switch 83. Thereby, the function for error recovery from the host device 200 can be omitted.

  As an example of error recovery processing corresponding to the type of error, in the case of an auto cutter error occurrence state, the movable blade 43 is moved to the home position in order to execute error recovery processing including initialization processing of the paper cutting unit 150 This can reduce the time and effort of the user, including the operations to be performed. In addition, when the internal state is the normal state, the PF-switch 83 can function as a paper transport instruction unit, a macro execution instruction unit, a self test execution instruction unit, and the like. That is, the apparatus cost can be reduced by assigning various functions to one operation unit.

  Further, since the error recovery process is executed by pressing the PF-switch 83, the error recovery process time can be shortened and the loss of received data can be prevented as compared with the initialization by turning off the power. Furthermore, when the printer apparatus 100 is used by being incorporated in some system, it is assumed that the power switch 81 cannot be turned on / off alone, but such a problem can be solved.

  In the above embodiment, when an unrecoverable error occurs, a special error recovery process is not executed. However, some process may be defined. For example, when an unrecoverable error occurs and the PF-switch 83 is pressed, it may be possible to notify the user of the error by e-mail, generation of electronic sound, wireless communication, or the like.

  In the above embodiment, the execution start trigger by the process execution unit is the press of the PF-switch 83, but the press of other switches / buttons may be the trigger. For example, when a button for opening and closing the roll paper cover 21 is mounted, an error recovery process corresponding to the type of error may be executed with the pressing thereof as a trigger. In addition, the form of the operation element is arbitrary, such as adopting a dip switch or a touch panel as the operation unit 160.

  In the above embodiment, the printer device 100 is used in combination with the host device 200. However, the present invention is applied to a printer device that can operate alone (a printer device having a print data generation function). May be. Further, the present invention may be applied not only to the printer device 100 but also to various electronic devices having an automatic cut mechanism.

  Further, it is possible to provide each function and each process of the printer apparatus 100 shown in the above embodiment as a program. Further, the program can be provided by being stored in various recording media (CD-ROM, flash memory, etc.). That is, a program for causing a computer to function as each component of the printer apparatus 100 and a recording medium on which the program is recorded are also included in the scope of rights of the present invention. In addition, the system configuration and processing steps of the printing system SY can be appropriately changed without departing from the gist of the present invention, regardless of the above-described embodiments.
