Description

The present invention relates to a printer.

The printer includes a printer device for printing print data on a print medium such as paper, and various portable information including print data as an external device (a mobile phone terminal such as a personal computer or a smartphone, a tablet type information terminal, etc.). Of course, it is equipped with a communication interface for receiving from terminals, cameras, etc.), and in addition to these, when an error condition such as a paper jam occurs in the printer device, it is notified to the user by sound or light. Generally, an alarm device for notification, an output device such as a display or a speaker, an input device such as a button or a touch panel, etc. are installed as standard equipment.

On the other hand, the usage patterns of printers are diversifying year by year, and in recent years, the demand for inexpensive printers is increasing. In order to realize such a printer, it is effective to narrow down the functions to be mounted on the printer, that is, to mount only the minimum necessary functions and omit the functions that are not essential as much as possible. Therefore, printers that reduce manufacturing costs by not installing alarms, output devices, or input devices have also been commercialized.

In a printer with such narrowed down functions, there will naturally be situations where inconvenience occurs because the functions installed as standard equipment in general printers are not installed. For example, a printer equipped with neither an alarm nor an output device has no way of notifying the user of an error state occurring in the printer. Therefore, Patent Documents 1 to 3 describe that in such a printer, an error state is notified to a user by using an operating sound of a motor.

By the way, in the memory of the printer, the setting data necessary for driving the printer device (various setting values such as print density and print mode, the resistance value of the thermal head, etc.) and the maintenance data necessary for the maintenance and inspection of the printer (cumulative printing). The number of sheets, the cumulative number of times each part has been used, data indicating the mechanical characteristics of each part (generally measured at the time of shipment from the factory and stored in a memory), error history, etc.) are stored as unique data of the printer.

Unique data is important data that each printer keeps holding individually. For example, if a part of the printed circuit board that constitutes the control unit of the printer has a problem and it is necessary to replace it, the unique data stored in the memory of the original printed circuit board is taken out and a new print is made. By migrating to the memory of the board, the unique data is inherited as it is.

Here, in the case of a general printer equipped with an output device such as a display or a speaker, the unique data can be taken out from the output device. Further, even if the output device cannot be used due to a failure or the like, the unique data can be taken out by using an external device connected via the communication interface. Since it is relatively unlikely that both the output device and the communication interface will be unavailable, it is unlikely that there will be no way to retrieve the unique data.

However, printers with limited functions as described above may not be equipped with an output device. In this case, the unique data can only be retrieved using an external device connected via a communication interface for communication. If the interface is damaged and cannot be used, there is no way to retrieve unique data. In this case, the unique data is substantially lost, and when the printed circuit board is replaced, the unique data cannot be inherited by a new printed circuit board.

The present invention has been made to solve such a problem, and an object of the present invention is to provide a technique capable of extracting data stored in a memory of a printer without going through a communication interface.

The present invention has taken the following measures in order to achieve such an object.
That is, the present invention is a printer.
A print unit that outputs print data to a print medium,
A memory that stores unique data of your own machine,
A first data output unit that outputs the unique data stored in the memory via a communication interface, and
By converting each of the series of data values included in the unique data stored in the memory into frequency values and switching the drive frequency of the motor included in the print unit one after another according to the obtained series of frequency values. A second data output unit that outputs the unique data as an operating sound of the motor,
A second data output unit activation unit that activates the second data output unit and outputs the unique data to the second data output unit in response to a predetermined trigger, and a second data output unit activation unit.
To prepare for.

From the rotating motor, an operating sound (vibration sound) having a frequency corresponding to the rotation speed is generated. The rotation speed of the motor is defined by the drive frequency. That is, the motor generates an operating sound having a frequency corresponding to the drive frequency (typically, a frequency that matches the drive frequency). In the above configuration, the drive frequency of the motor is switched one after another according to the frequency value converted from each of the series of data values included in the unique data. Therefore, the frequency of the operating sound generated from the motor is also switched one after another, and by frequency analysis of this operating sound, a series of drive frequencies and, by extension, a series of data values can be obtained. As described above, in the above configuration, the unique data stored in the memory of the printer can be taken out without going through the communication interface.

Preferably, in the printer,
The predetermined trigger is that the sensor included in the print unit detects a predetermined state.

According to this configuration, even if the printer is not equipped with an input device such as a button or touch panel, an operator (typically, a worker of a manufacturer who performs failure repair, maintenance, inspection, etc. is assumed). However, by performing an operation such that the sensor detects a predetermined state, the unique data can be output as the operating sound of the motor.

Preferably, in the printer,
The sensor is a light receiving sensor,
In the predetermined state, the state in which the light receiving amount of the sensor is smaller than the predetermined value is maintained for a predetermined time or longer.

According to this configuration, the operator can output the unique data as the operating sound of the motor by performing a simple operation such as closing the light receiving window of the sensor with a finger or the like for a predetermined time or longer.

Preferably, the printer is
A housing having a main body having an opening and a lid for closing the opening, and accommodating the printed portion inside.
Equipped with
When the lid is open, the driving force of the motor is not transmitted to the object to be driven.

While the motor is rotating to output unique data, the operator would naturally open the lid to hear (record) its operating sound, but in the above configuration, the lid is opened. Since the driving force of the motor is not transmitted to the object to be driven, the motor is not unnecessarily loaded due to the output of the unique data.

According to the present invention, since the unique data stored in the memory of the printer can be output as the operating sound of the motor, the unique data can be taken out without going through the communication interface.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

<1. Printer configuration>
The configuration of the printer according to the embodiment will be described with reference to FIGS. 1 to 3. FIG. 1 is a diagram schematically showing the configuration of the printer 100. FIG. 2 is a diagram showing a state in which the lid portion 13 of the housing 1 of the printer 100 is opened. FIG. 3 is a block diagram showing a part of the functional configuration of the printer 100.

The printer 100 is a sublimation type thermal printer, and includes a housing 1, a printing unit 2 and a control unit 3 housed therein.

<Case 1>
The housing 1 includes a main body portion 11 and a lid portion 13 connected to the main body portion 11 via a hinge 12. By rotating the lid portion 13 around the hinge 12 so that the lid portion 13 is flipped upward (the state shown in FIG. 2), the opening portion 110 is formed in the main body portion 11, and the opening portion is formed. The roll paper 9 can be replaced via the 110.

<Print section 2>
The print unit 2 outputs print data to print paper which is a print medium (print medium). The print portion 2 is pivotally supported by a support portion 20 for pivotally supporting (rotatably supporting) the roll paper 9 on which the print paper is wound and a support portion 20 at a predetermined position inside the housing 1. A roller (feed roller) 21 for feeding the roll paper 9 and a roller (feed roller) 22 for feeding the fed roll paper 9 along a predetermined delivery path are provided. Both the feeding roller 21 and the feed roller 22 are cylindrical members whose axial length is slightly longer than the width direction of the roll paper 9, and are arranged in a horizontal posture at each predetermined position inside the housing 1. It is pivotally supported by bearings (not shown) at both ends.

A driven gear 221 is provided at one end of the feed roller 22. Further, the driving gear 222 is arranged at a position near the driven gear 221 and separated from the driven gear 221. A motor 223 for rotating the main gear 222 is connected to the shaft portion. The motor 223 is a pulse motor controlled by a pulse signal, and is assumed to be a stepping motor here. A transmission gear 224 that meshes with both gears 221, 222 is arranged between the main drive gear 222 and the driven gear 221 (FIG. 1). When the motor 223 rotates the main gear 222 in a state where the transmission gear 224 is meshed with both gears 221, 222, the transmission gear 224 and the driven gear 221 rotate in order in accordance with the rotation of the main gear 222, and the feed roller 22 rotates. As a result, the roll paper 9 is sent out along a predetermined sending path.

However, the transmission gear 224 is fixed to the lid portion 13, and when the lid portion 13 is closed, the transmission gear 224 is arranged at a position where it meshes with both gears 221,222 (FIG. 1), and when the lid portion 13 is opened. , Separated from both gears 221,222 (FIG. 2). That is, in the state where the lid portion 13 is opened, the driving force of the motor 223 is not transmitted to the driven gear 221 (and by extension, the feed roller 22 which is the driving object).

A thermal head 23 and a platen roller 24 are provided in the middle of the delivery path of the roll paper 9 so as to face each other with the delivery path interposed therebetween. Further, the ink ribbon 25 is supplied between the thermal head 23 and the platen roller 24 so as to overlap the roll paper 9. Ink (yellow (Y), magenta (M), cyan (C) color ink, or / and black (K) ink) was applied to the ink ribbon 25 along the long direction thereof. Areas and areas coated with a transparent overcoat material that protects the printed surface are provided alternately. Further, the ink ribbon 25 is wound around the supply side core 251 at one end and around the take-up side core 252 at the other end, and the cores 251,252 rotate in synchronization with each other to rotate the thermal head 23. At the position, the area coated with the ink and the area coated with the overcoat material are alternately sent out. When heat is applied from the thermal head 23 to the ink application region of the ink ribbon 25, the ink is transferred to the roll paper 9. Further, by applying heat to the coating area of the overcoat material in the ink ribbon 25, the overcoat material is applied to the roll paper 9 to which the ink is transferred.

A cutter 26 is provided in the middle of the delivery path of the roll paper 9 on the downstream side in the delivery direction from the thermal head 23 and the platen roller 24, and the roll paper 9 on which print data is output (printed) is provided. The cutter 26 cuts into a predetermined size. The cut roll paper 9 (print piece) is discharged from the discharge port 111 provided in the housing 1.

Sensors 27 are provided at each predetermined position inside the housing 1. Specifically, for example, a sensor 27 (ink ribbon detection sensor 27a) for detecting that the ink ribbon 25 has been loaded, a sensor 27 (roll paper detection sensor 27b) for detecting that the roll paper 9 has been loaded, and a roll paper. A sensor 27 (roll paper position detection sensor 27c) that detects that 9 has reached the position of the cutter 26, and a sensor (lid open / close detection sensor) that detects whether or not the lid 13 of the housing 1 is in the open state. ) (Not shown), etc. are provided. Each sensor 27a, 27b, 27c is composed of, for example, a sensor (so-called light receiving sensor) that detects the amount of light that arrives, converts it into an electric signal, and outputs it. In the following, when each sensor 27a, 27b, 27c is not distinguished, it is simply referred to as “sensor 27”.

<Control unit 3>
The substance of the control unit 3 is a printed circuit board on which various modules are mounted. Specifically, a memory 30 composed of an EEPROM or the like and a driver module 31 for controlling each unit 21 to 27 included in the print unit 2 to execute a series of print operations are mounted on the printed circuit board. .. Further, a circuit module for realizing each of the functional units 32 to 34 described later is mounted on the printed circuit board. Further, the printed circuit board is provided with a communication interface 35 for communicating with an external device (for example, a personal computer, a portable information terminal, a camera, etc.). The communication interface 35 includes a port (for example, a USB port) 351 provided in the housing 1.

<2. Output of unique data>
Unique data 301 of the own machine (printer 100) is stored in the memory 30. Specifically, the unique data 301 is used for maintenance and inspection of the printer 100, for example, setting data necessary for driving the print unit 2 (various set values such as print density and print mode, resistance value of the thermal head 23, etc.). Necessary maintenance data (cumulative number of prints, cumulative number of uses of each part, data showing mechanical characteristics of each part, error history, etc.). The printer 100 has a function of outputting the unique data 301. Hereinafter, this function will be specifically described.

<2-1. Functional configuration>
Functional elements related to the output of the unique data 301 will be described with reference to FIGS. 1 to 3 as well as FIGS. 4 and 5. FIG. 4 is a diagram showing a configuration example of the conversion table 302 used for outputting the unique data 301. FIG. 5 is a diagram for explaining the timing for switching the drive frequency of the motor 223.

The control unit 3 includes a first data output unit 32, a second data output unit 33, and a second data output unit activation unit 34 as functional elements related to the output of the unique data 301.

The first data output unit 32 outputs the unique data 301 via the communication interface 35. Specifically, when the first data output unit 32 acquires the output command of the unique data 301 from the external device connected via the communication interface 35, the first data output unit 32 reads the unique data 301 from the memory 30 and communicates this. It transmits to an external device via the interface 35. As a result, the unique data 301 is output to the external device (specifically, for example, an output device such as a display or a speaker included in the external device).

The second data output unit 33 is a functional element that outputs the unique data 301 as the operating sound of the motor 223 included in the print unit 2, and includes a conversion unit 331 and a drive control unit 332.

The conversion unit 331 reads out the unique data 301 from the memory 30 and converts each of the series of data values included in the unique data 301 into frequency values.

Specifically, the conversion from the data value to the frequency value is performed using, for example, the conversion table 302 stored in the memory 30. FIG. 4 shows a configuration example of the conversion table 302 for hexadecimal data. As shown here, in the hexadecimal conversion table, each of the 16 data values (0, 1, 2, ..., E, F) that can be taken as data values has 16 different frequencies. It is associated with a value. Here, each of the 16 data values arranged in ascending order is associated with the frequency value corresponding to each of the 16 scales arranged in ascending order. For example, in 8-bit data represented by two hexadecimal digits, the data value "0xA0" is the frequency value "440 (Hz)" in which the first digit data value is the musical scale "la" when this conversion table 302 is used. And the data value of the second digit is converted to the frequency value "1175 (Hz)" of the musical scale "re". Needless to say, each frequency value associated with each data value is not limited to the one exemplified in the conversion table 302 of FIG. 4, and can be arbitrarily specified.

When performing conversion using the conversion table 302, the conversion unit 331 first converts each of the series of data values included in the unique data 301 read from the memory 30 into hexadecimal numbers according to the conversion table 302 as necessary (FIG. 4). In the case of the conversion table 302 exemplified in the above, hexadecimal conversion is performed. Then, each data value converted to a base is converted into a frequency value using the conversion table 302. As a result, a series of data values included in the unique data 301 are converted into a series of frequency values.

The drive control unit 332 sequentially sets the drive frequency of the motor 223 included in the print unit 2 (here, the pulse frequency of the pulse signal for driving the motor 223) according to a series of frequency values obtained by the conversion unit 331. Switch. That is, the drive control unit 332 reads out the series of frequency values one by one, generates a pulse signal having each frequency value as a pulse frequency, and transmits the pulse signal to the motor driver 311 connected to the motor 223 one after another. give. The motor driver 311 supplies a current to the motor 223 at a timing corresponding to a given pulse signal. As a result, the motor 223 rotates while changing the rotation speed according to the pulse frequency of the pulse signals given one after another.

For example, when the data value of the first digit is "440 (Hz)" and the data value of the second digit is "1175 (Hz)" and the converted data value is "0xA0", the drive control unit 332 As shown in FIG. 5, first, a pulse signal having a pulse frequency of 440 (Hz) is given to the motor driver 311 for a predetermined time (for example, 1.0 second), and then for a minute time (for example, 0.1 second). ), Then the pulse signal having a pulse frequency of 1175 (Hz) is given to the motor driver 311 for the same predetermined time (for example, 1.0 second) as before. Then, the motor 223 first rotates at a rotation speed corresponding to the pulse frequency 440 (Hz) for 1.0 second, goes through a rotation stop state for 0.1 second, and then reaches a pulse frequency of 1175 (Hz). Rotate for 1.0 second at the corresponding rotation speed.

In the above example, a minute time during which the pulse signal is stopped (that is, a minute time during which the rotation of the motor 223 is stopped) is provided so that the frequency value can be separated. The mode of the pulse signal for indicating this delimiter is not limited to this, and for example, a pulse signal having a pulse frequency of a frequency value not shown in the conversion table 302 (that is, a frequency value not assigned to any data value) is used. By giving only a short time, the frequency value delimiter may be known.

From the rotating motor 223, an operating sound (vibration sound) having a frequency corresponding to the rotation speed is generated. The rotation speed of the motor 223 is defined by the drive frequency of the motor 223. That is, the motor 223 generates an operating sound having a frequency corresponding to the drive frequency (typically, a frequency that matches the drive frequency). As described above, the drive frequency of the motor 223 rotated under the control of the drive control unit 332 is switched one after another according to the frequency value converted from each of the series of data values included in the unique data 301. Therefore, the frequency of the operating sound generated from the motor 223 is also switched one after another, and by frequency analysis of this operating sound, a series of drive frequencies and, by extension, a series of data values included in the unique data 301 can be obtained.

The second data output unit activation unit 34 activates the second data output unit 33 in response to a predetermined trigger to output the unique data 301. This trigger can be appropriately specified by the designer of the printer 100 or the like. For example, here, the sensor 27 (any of a plurality of sensors 27a, 27b, 27c, or a predetermined predetermined sensor among the plurality of sensors 27a, 27b, 27c) included in the print unit 2 is a predetermined sensor. Detecting a state can be a trigger. In this case, the "predetermined state" is preferably a state that can be distinguished from a state that is spontaneously formed or an error state that can be assumed in the printer 100, and the operator (typically, failure repair or maintenance inspection). It is preferable that the worker of the manufacturer who performs the above is assumed) is intentionally formed by performing some operation.

For example, a state in which the light receiving amount of the roll paper detection sensor 27b is smaller than a sufficiently small predetermined threshold value (threshold value sufficiently smaller than the threshold value used for determining the presence or absence of the roll paper 9) is a predetermined time (for example, 10.0). A state that is maintained for more than a second) can be regarded as a "predetermined state". In this case, the operator flips the lid portion 13 upward, puts his / her hand through the opening 110 of the main body portion 11, and closes the light receiving window of the roll paper detection sensor 27b with a finger or the like for a predetermined time or longer. Can form a predetermined state.

Further, for example, a state in which the light receiving amount of the roll paper detection sensor 27b is larger than a sufficiently large predetermined threshold value (threshold value sufficiently larger than the threshold value used for determining the presence or absence of the roll paper 9) is a predetermined time (for example, 10. A state maintained for 0 seconds or longer may be referred to as a "predetermined state". In this case, the operator flips up the lid portion 13 upward, inserts a handy light or the like through the opening 110 of the main body portion 11, and shines light on the light receiving window of the roll paper detection sensor 27b for a predetermined time or longer. By performing the operation, a predetermined state can be formed.

<2-2. Processing flow>
Next, the flow of processing relating to the output of the unique data 301 will be described with reference to FIGS. 1 to 5 and FIG. FIG. 6 is a diagram showing a flow of processing related to the output of the unique data 301, and FIG. 6A shows a flow of processing performed in a normal situation in which the communication interface 35 is functioning normally. b) shows the flow of processing performed in a situation where the communication interface 35 is damaged and is not functioning normally.

In a normal situation where the communication interface 35 is functioning normally, when the operator wants to retrieve the unique data 301 stored in the memory 30, the operator connects an external device to the printer 100, and the communication interface 35 is connected to the external device. The output command of the unique data 301 is input to the printer 100 via the printer 100.

When the output command of the unique data 301 is acquired via the communication interface 35 (YES in step S11), the first data output unit 32 reads the unique data 301 from the memory 30 and uses the unique data 301 via the communication interface 35. To the external device (step S12). That is, in this case, the unique data 301 is output from the printer 100 via the communication interface 35.

On the other hand, when it is desired to retrieve the unique data 301 stored in the memory 30 in a situation where the communication interface 35 is damaged and is not functioning normally, the operator detects a predetermined state defined as a trigger. An operation for causing 27 to detect is performed. Specifically, for example, the lid portion 13 is flipped up, a hand is put in through the opening 110 of the main body portion 11, and the light receiving window of the roll paper detection sensor 27b is closed with a finger or the like for a predetermined time or longer. The second data output unit activation unit 34 constantly monitors whether or not the sensor 27 has detected a predetermined state, and if it is determined that the sensor 27 has detected a predetermined state (YES in step S21), this is determined. As a trigger, the second data output unit 33 is activated (step S22).

When the second data output unit 33 is activated by the second data output unit activation unit 34, the second data output unit 33 outputs the unique data 301 as an operating sound of the motor 223 (step S23). Specifically, first, the conversion unit 331 reads out the unique data 301 from the memory 30 and converts each of the series of data values included in the unique data 301 into frequency values (step S231). Subsequently, the drive control unit 332 switches the drive frequency of the motor 223 one after another according to a series of frequency values obtained by the conversion unit 331 (step S232).

Then, the motor 223 rotates while changing the rotation speed one after another according to the drive frequency that is switched one after another. As described above, the rotating motor 223 generates an operating sound having a frequency corresponding to the rotation speed. For example, the operator opens the lid 13 and records the operation sound to acquire the voice data of the operation sound, and frequency-analyzes the obtained voice data. As a result, a series of drive frequencies are specified, and by converting this into a data value, the unique data 301 is obtained.

<3. Effect>
In the above configuration, since the unique data 301 stored in the memory 30 of the printer 100 can be output as the operating sound of the motor 223, the unique data 301 can be taken out without going through the communication interface 35. ..

Further, in the above configuration, the second data output unit 33 is activated by the sensor 27 included in the print unit 2 detecting a predetermined state as a trigger. Therefore, even when the printer 100 is not equipped with an input device such as a button or a touch panel, the operator performs an operation such that the sensor 27 detects a predetermined state, whereby the unique data 301 is transferred to the motor 223. It can be output as the operation sound of.

Further, in the above configuration, the sensor 27 is a light receiving sensor, and the above-mentioned predetermined state can be maintained in a state where the light receiving amount of the sensor 27 is smaller than the predetermined value for a predetermined time or longer. In this case, the operator can output the unique data 301 as the operating sound of the motor 223 by performing a simple operation such as closing the light receiving window of the sensor 27 with a finger or the like for a predetermined time or longer.

Further, in the above configuration, the housing 1 includes a main body portion 11 and a lid portion 13, and the driving force of the motor 223 is transmitted to the feed roller 22 which is a drive target in a state where the lid portion 13 is opened. It is designed not to be done. While the motor 223 is being rotated for the output of the unique data 301, it is considered that the operator naturally opens the lid 13 in order to hear (record) the operation sound. However, in this configuration, the lid 13 is used. When is opened, the driving force of the motor 223 is not transmitted to the feed roller 22, so that the motor 223 is not unnecessarily loaded due to the output of the unique data 301.

Of course, it is also possible to hear the operating sound of the motor 223 with the lid portion 13 closed. When the output of the unique data 301 by the operation sound of the motor 223 is performed with the lid portion 13 closed, it is preferable to remove the roll paper 9 from the delivery path. By doing so, the load for rotating the feed roller 22 becomes sufficiently small, and even if the driving force of the motor 223 is transmitted to the feed roller 22, the load applied to the motor 223 becomes sufficiently small.

<4. Other embodiments>
In the above embodiment, the conversion unit 331 performs the conversion from the data value to the frequency value using the conversion table 302, but this conversion may be performed by a method other than using the conversion table 302. For example, a predetermined mathematical formula (conversion formula) may be stored in the memory 30, and the data value may be converted into a frequency value using this conversion formula. Needless to say, the conversion table 302, the conversion formula, etc. are backed up by the operator in a place separate from the printer 100, and a series of drive frequencies obtained by frequency analysis of the voice data of the operating sound of the motor 223. Must be ready to be used to convert to a data value.

In the above embodiment, when the print unit 2 includes, for example, a sensor (so-called tag sensor) that reads data from an RF tag or the like, the tag sensor reads predetermined data in order to activate the second data output unit 33. It may be used as a trigger for. In this case, the operator can output the unique data 301 as the operating sound of the motor 223 by performing an operation of causing the tag sensor to read the RF tag in which the predetermined data is described.

Further, the trigger for activating the second data output unit 33 is not limited to the sensor 27 detecting a predetermined state. For example, when the printer 100 includes an input device such as a button or a touch panel, the input of a predetermined instruction may be used as a trigger for activating the second data output unit 33.

In the above embodiment, the communication interface 35 is provided with a USB port 351 (so-called USB interface), but the communication interface 35 is not limited to this, and for example, a wireless LAN, a wired LAN, or the like. It may be various existing communication interfaces such as an infrared interface, Bluetooth (registered trademark), and the like.

In the above embodiment, the printer 100 is a sublimation type thermal printer, but the present invention is applied to a thermal printer other than the sublimation type and various printers other than the thermal printer (inkjet printer, dot printer, etc.). can do. The present invention is also particularly useful in printers without alarms, output devices, and input devices, but of course also in printers with at least one of these elements. For example, if the present invention is applied to a printer provided with an output device, even if both the communication interface and the output device are damaged, the unique data 301 can be output without using either of them.

Other configurations can be variously modified without departing from the spirit of the present invention.
