And recording means for performing recording.

  According to another aspect of the invention, there is provided a recording method for a recording apparatus that performs recording using a thermal head on multiple thermal paper that is configured by superimposing a plurality of printed pages, the print data and the print data being Based on the input step of inputting print page information including information designating which page of the multiple thermal paper is to be printed or not printed, and the print data and print page information input in the input step A generation step of generating heat pulse data to be applied to the thermal head so that printing is performed on the thermal paper of the page reflecting the designation of the print page information, and based on the heat pulse data generated in the generation step And a recording step of recording by applying a heat pulse to the thermal head.

  Therefore, according to the present invention, based on the input print data and print page information, heat pulse data is generated so that printing is performed on the thermal paper of the page reflecting the designation of the print page information. Based on this, recording can be performed from the thermal head. Therefore, when recording is performed using a bag-binding thermal paper that is composed of a set of a plurality of printed pages, for example, information that is not desired to be seen by a third party is printed on a page inside the bag binding. It becomes possible.

  Hereinafter, preferred embodiments of the present invention will be described more specifically and in detail with reference to the accompanying drawings.

  In this specification, “recording” (sometimes referred to as “printing”) does not represent only the case of forming significant information such as characters and graphics. In addition to this, an image, a pattern, a pattern, or the like is widely formed on a recording medium regardless of whether it is significant involuntary, or whether it is manifested so that a human can perceive it visually, or It also represents the case where the medium is processed.

  FIG. 1 is a schematic perspective view of a handy terminal (portable terminal) incorporating a thermal printer as a typical embodiment of the present invention.

  As shown in FIG. 1, the portable terminal 1 displays a switch 3 for turning on / off the main power supply, a keyboard 4 for inputting values of electricity, gas, water usage meter, customer information, meter reading route, and the like. A liquid crystal display (LCD) 5 is provided. Also, a battery storage unit 6 for inserting a battery for operating the portable terminal, a CF card storage unit 7 for inserting a CF (Compact Flash) memory card used for backup of the meter reading result, and a thermal line printer 2 for printing the meter reading result. Is provided. Furthermore, the portable terminal 1 includes a printed board (not shown) on which a control circuit is mounted.

  FIG. 2 is a diagram showing a bag-bound thermal paper used in the thermal line printer 2 built in the portable terminal.

  In FIG. 2, 9 is a bag-binding thermal paper, 9-a is a glued portion, and 9-b is an air hole.

  FIG. 3 is a block diagram showing a control configuration of the mobile terminal.

  In FIG. 3, reference numeral 21 denotes a main CPU that controls the entire handy terminal. The main CPU 21 includes a ROM 23 for storing a program for operating the main CPU 21, a RAM 22 for temporarily storing customer data, meter reading results, and the like for transmitting / receiving data and status to / from a sub CPU 30 described later. A data buffer 24 is connected. Note that a heat table described later is stored in a memory such as a ROM.

  The program stored in the ROM 23 includes a print page data generation program for generating print page data from print data such as characters and ruled lines and print page information described later. The main CPU 21 converts the print data stored in the RAM 22 into print page data by the print page data generation program, and then transfers the converted data to the sub CPU 30 through the data buffer 24.

  Connected to the sub CPU 30 are a motor control circuit 33, a thermal line head control circuit 34, a ROM 32 storing a program for operating the sub CPU 30, and a RAM 31 used as various work areas of the sub CPU 30. The motor control circuit 33 controls the rotation of the motor 35 that drives the platen roller 36 based on the transport pulse signal output from the sub CPU 30 or the like.

  Connected to the thermal line head control circuit 34 is a thermal line head (hereinafter referred to as a head) 37 in which heating elements that transmit thermal energy to the thermal paper are arranged in a line. Then, heat data, a synchronous clock, a latch pulse, and strobe signals (B1 to B4 strobe) of each block are serially transmitted to the head 37 to control the heat generation of each heating element of the head.

  FIG. 4 is a block diagram showing the internal configuration of the head 37.

  The head 37 is provided with a heating element 204 composed of a plurality of heating elements arranged in the width direction of the thermal paper (the direction perpendicular to the thermal paper transport direction). The plurality of heating elements of the heating element 204 are divided into four blocks, and a dedicated driver 203 is provided for each block. In FIG. 4, these are illustrated as a B1 driver, a B2 driver, a B3 driver, and a B4 driver. A current is supplied from the heating element power source to the heating element selected by these drivers to cause the heating element to generate heat. By applying thermal energy from the heating element 204 to the thermal paper at the timing when the thermal paper passes between the heating element 204 and the platen roller 36, the thermal paper is colored to perform printing.

  In order to select a heating element that generates heat, heat data for one row is serially input to the shift register 201 simultaneously with the synchronous clock. In the shift register 201, the serially input heat data is converted into parallel data and output to the latch register 202. The latch register 202 receives a latch pulse indicating that the heat data for one row is ready, and latches the heat data. The driver 203 drives the heating element for a specified time based on a heat table (described later) selected by the sub CPU 30. At this time, one line of heating elements is driven by delay division, and a reduction in power supply voltage caused by simultaneously driving a large number of heating elements is reduced.

  The thermal line printer (hereinafter referred to as printer) 2 includes a heat table corresponding to the type of thermal paper, the printing method, and the number of printed pages. The sub CPU 30 selects a heat table from print page information included in the print page data transferred from the main CPU 21.

  The RAM 31 is used as various work areas of the sub CPU 30 to temporarily store print page data transferred from the main CPU 21 via the data buffer 24, head heat data converted from the print page data, and the like. Also used.

  Next, two embodiments relating to a recording operation when a printer of the portable terminal having the above configuration prints on a plurality of thermal papers will be described.

  FIG. 5 is a diagram conceptually illustrating a state where printing is performed on a plurality of thermal paper sheets.

  The thermal paper first page 100a and the thermal paper second page 100b shown in FIG. 5 constitute a set of two thermal papers that are pasted together by the glue portion 100e. The thermal paper first page 100a and thermal paper second page 100b are coated with color formers 100c and 100d that develop color when heated to the temperature lower than the minimum color development temperature on the front side (right side in the figure). The color formers 100c and 100d may be color formers having the same characteristics. However, a combination of color formers having a lower color development lower limit temperature for developing the color former 100c than a lower color development temperature for producing the color former 100d is more preferable.

  When applying thermal energy from the front side, if the thermal energy required to heat the thermal agent 100c to the color development lower limit temperature or higher is E1, the thermal paper 100d can be heated to the color development lower limit temperature or higher by using thermal paper. Thermal energy will be applied through the first page 100a. For this reason, heat energy (E1 + E2) larger than E1 is required.

The thermal energy (E) generated by the heating element of the thermal line head is
E = P × T, P: applied power, T: applied time. Thus, the thermal energy (E) is the product of the applied power (P) and the applied time (T). If the applied power is constant, the necessary heat energy can be adjusted by changing the applied time.

  In this embodiment, F1 is the application time for obtaining the thermal energy necessary for heating the color former 100c on the first page 100a of the thermal paper to the color development lower limit temperature or higher. On the other hand, the application time for obtaining the thermal energy necessary for heating the color former 100d on the second page 100b of the thermal paper to the color development lower limit temperature or higher is defined as (F1 + F2).

  Therefore, when printing only the first page of thermal paper (not printing the second page of thermal paper), power is applied to the head 37 for the time F1. Similarly, when printing the second page of thermal paper (printed on the first and second pages of thermal paper), electric power is applied to the head 37 for the time (F1 + F2).

  However, in practice, it is necessary to adjust the application time depending on the type of thermal paper, the change in applied power due to the decrease in voltage accompanying the consumption of the battery of the mobile terminal, the effect of the thermal storage energy of the head that heats the thermal paper, etc. There is. Therefore, in this embodiment, the application time is stored as a heat table for each of these adjustment factors.

  FIG. 6 is a diagram illustrating a heat table used in the first embodiment.

  As shown in FIG. 6, the table defines the type of thermal paper (X: thermal paper X, Y: thermal paper Y), applied voltage, and applied time (F1, F2,...) For each head temperature. Yes.

  Next, a flow of print data conversion processing and an example of a print result will be described with reference to FIG.

  As shown in FIG. 7, the print data 701 is composed of 1-bit data indicating the presence / absence of dots, and represents “H” three characters A to C. Three-bit printed page data 703 is created by adding the type of thermal paper, the number of pages of the thermal paper, and the number of printed pages and the presence / absence of hidden character setting for each character data as print page information 702. Hidden character setting means that the first page of information is printed on the first and second pages of the thermal paper, and only the first page is colored with blank pixels such as information that you do not want to display on the first page of the thermal paper. Is a setting for preventing reading.

  Bit 2 of the printed page data 703 represents the type of thermal paper. This time, bit 2 = 0, and the heat table group of thermal paper X is selected. Bit 1 and bit 0 represent the number of printed pages, and are used to create heat data.

  The heat data is composed of 1-bit data, and is divided into heat data f1 for print page 1 and heat data f2 for print page 2.

  When bit 1 and bit 0 of the print page data are “00”, the f1 heat data is converted to “0” and the f2 heat data is converted to “0”. When bit 1 and bit 0 are “01”, f1 heat data is converted to “1” and f2 heat data is converted to “0”. When bit 1 and bit 0 are “10”, f1 heat data is converted to “1” and f2 heat data is converted to “1”.

  As described above, based on the heat table selected from the print page data 703 and the heat data converted from the print page data, the heat pulses (f1p, f2p) are input for each heating element of the head 37.

  FIG. 8 is a time chart showing a heat pulse and a paper feed pulse for each of the three printed characters A to C. Note that the active level of the heat pulses (f1p, f2p) is “Low”.

  As shown in FIG. 8, the heat pulses (f1p, f2p) are two continuous paper feed pulses (sp) input to the motor control circuit 33 in order to convey the thermal paper by rotating the platen roller 36. It is input to the head 37 at a timing in between.

  That is, since the number of printed pages is “1” for the character A, only the heat pulse f1p is input, but for the characters B and C, the number of printed pages is “2”, so two heat pulses are input. Both (f1p, f2p) are input. The application time spans the total time (F1 + F2) of the two heat pulses (f1p, f2p). By applying thermal energy to the same part of the thermal paper, the character A is printed only on the first page, and the character B is printed on both the first and second pages.

  In addition, the character C is printed on the first page together with the character and its margins and surroundings to become a black solid, and the character C is printed on the second page. In this way, in order to perform black solid printing and reliably hide the print content, the lower color forming temperature at which the color former 100c on the first page 100a is developed is set to be lower than the lower color development temperature at which the color former 100d on the second page 100b is developed. It is preferable to make it small.

  FIG. 9 is a diagram illustrating a print example obtained by the recording control according to the first embodiment.

  For this printing, a slip made of two sheets of thermal paper in the form of a bag shown in FIG. 2 is used. FIG. 9A shows print data, in which the address is recorded in the first and second lines, and the transfer account and the amount are recorded in the third and fourth lines. The addresses on the first and second lines are information necessary for the delivery person to definitely deliver the slip to the recipient, and must be printed on the first page of the slip. On the other hand, the transfer destination and amount of money in the 3rd and 4th lines are information that the third party does not want to know, and it is necessary to print on the second page inside the bag binding slip and not on the first page. It is.

  In that case, the number of printed pages is “1” for the first and second lines of print data shown in FIG. 9A, no hidden characters, and the number of printed pages is “2” for the third and fourth lines of print data. Set print page with print and print. As a result, printing as shown in FIG. 9B can be performed. The black solid printing performed on the first and third lines of the first page of the bag binding slip has the purpose of making the transfer account and the amount of money printed on the second page invisible from the table.

  Therefore, according to the embodiment described above, when printing is performed on the bag-bound thermal paper, the application time of the heat pulse applied to the head is controlled by printing on the first page of the table and printing on the second page of the bag. And appropriate printing can be performed. As a result, it is possible to control information related to privacy to be printed on the second page that is not visible to a third party, and information that is not so to be printed on the first page. In addition, the confidentiality of the information can be further ensured by printing the first page in black and printing the information related to privacy on the second page corresponding to the place.

  Here, an example of printing by applying thermal energy from the back side of the thermal paper will be described.

  FIG. 10 is a diagram conceptually showing a state of printing on a plurality of thermal paper sheets according to this embodiment.

  The thermal paper first page 100a and thermal paper second page 100b shown in FIG. 10 constitute a set of two thermal papers that are pasted together by the glue portion 100e. The thermal paper first page 100a and thermal paper second page 100b are coated with color formers 100c and 100d that develop color when heated to the temperature lower than the minimum color development temperature on the front side (right side in the figure). The color formers 100c and 100d may be color formers having the same characteristics, but a combination of color formers in which the minimum color development temperature for color development of the color development agent 100c is higher than the minimum color development temperature for color development of the color development agent 100d is more preferable.

  When heat energy is applied from the back side, the heat energy required to heat the thermal agent 100d to the color development lower limit temperature or higher is set to E3. Thermal energy will be applied through the second page 100b. For this reason, heat energy (E3 + E4) larger than E3 is required.

The thermal energy (E) generated by the heating element of the thermal line head is
E = P × T, P: applied power, T: applied time. Thus, the thermal energy (E) is the product of the applied power (P) and the applied time (T). If the applied power is constant, the necessary heat energy can be adjusted by changing the applied time.

  In this embodiment, the application time for obtaining with the head 37 the thermal energy necessary for color development of the color former 100d on the thermal paper second page 100b is B1. On the other hand, the application time for obtaining the thermal energy necessary for developing the color former 100c of the thermal paper first page 100a with the head 37 is defined as (B1 + B2).

  Therefore, when printing only the second page of thermal paper (not printing the first page of thermal paper), power is applied to the head 37 for the time B1. Similarly, when printing the first page of thermal paper (printed on the first and second pages of thermal paper), electric power is applied to the head 37 for the time (B1 + B2).

  However, in practice, it is necessary to adjust the application time depending on the type of thermal paper, the change in applied power due to the decrease in voltage accompanying the consumption of the battery of the mobile terminal, the effect of the thermal storage energy of the head that heats the thermal paper, etc. There is. Therefore, in this embodiment, the application time is stored as a heat table for each of these adjustment factors.

  FIG. 11 is a diagram illustrating a heat table used in the second embodiment.

  As shown in FIG. 11, this table includes types of thermal paper (X: thermal paper X, Y: thermal paper Y), a surface to which heat energy is applied (F: front application, B: back application), applied voltage, The application time (B1, B2,...) Is defined for each head temperature.

  Next, a flow of print data conversion processing and an example of a print result will be described with reference to FIG.

  As shown in FIG. 12, the print data 1201 is composed of 1-bit data indicating the presence / absence of a dot, and represents two “H” characters D to E. 4-bit print page with print data 1201 as print page information 1202, including the type of thermal paper, the number of pages of thermal paper, the designation of the front and back of the application surface, and the number of print pages for each character data and whether or not hidden characters are set Data 1203 is created. Hidden character setting means that white pixels such as information that you do not want to display on the page close to the heat application surface on the thermal paper and the surrounding color are colored, and information printed on other pages of the thermal paper cannot be read from that page It is a setting to do.

  Bit 3 of the print page data 1203 represents an application surface for heating the thermal paper, indicating 0: front application, 1: back application. In this embodiment, bit 3 = 1, indicating application to the back side of the second page 100b of the thermal paper. Bit 2 of the printed page data 1203 represents the type of thermal paper. In this embodiment, bit 2 = 1 and the heat table group of thermal paper Y is selected. Bit 1 and bit 0 represent the number of printed pages, and are used to create heat data.

  The heat data is composed of 1-bit data, and is divided into heat data b1 for print page 2 and heat data b2 for print page 1.

  When bit 1 and bit 0 of the print page data are “00”, b1 heat data is converted to “0” and b2 heat data is converted to “0”. When bit 1 and bit 0 are “01”, b1 heat data is converted to “1” and b2 heat data is converted to “0”. When bit 1 and bit 0 are “10”, b1 heat data is converted to “1” and b2 heat data is converted to “1”.

  As described above, based on the heat table selected from the print page data 1203 and the heat data converted from the print page data, the heat pulses (b1p, b2p) are input for each heating element of the head 37.

  FIG. 13 is a time chart showing a heat pulse and a paper feed pulse for each of the two printed characters D to E. Note that the active level of the heat pulses (b1p, b2p) is “Low”.

  As shown in FIG. 13, the heat pulses (b1p, b2p) are two continuous paper feed pulses (sp) input to the motor control circuit 33 in order to rotate the platen roller 36 and transport the thermal paper. It is input to the head 37 at a timing in between.

  That is, since the number of printed pages is “1” for the letter D, the heat pulse b1p is applied for the time B1. On the other hand, since the number of printed pages is “2” for the letter E, two heat pulses (b1p, b2p) are both input. The application time spans the total time (B1 + B2) of the two heat pulses (b1p, b2p). By applying thermal energy to the same part of the thermal paper, the character D is printed only on the second page, and the character E is printed on both the first and second pages.

  When heat energy is applied from the back side of the thermal paper in this way, the lower limit color temperature of the thermal paper is used to reliably print on the second page 100b while reliably preventing printing of characters on the first page 100a. It is desirable to have the following conditions. In other words, it is preferable that the lower limit temperature for color development of the color former 100c on the first page 100a is higher than that of the color former 100d on the second page 100b.

  FIG. 14 is a diagram illustrating a print example obtained by the recording control according to the second embodiment.

  For this printing, a slip made of two sheets of thermal paper in the form of a bag shown in FIG. 2 is used. FIG. 14A shows print data, in which the address is recorded in the first and second lines, and the transfer account and the amount are recorded in the third and fourth lines. The addresses on the first and second lines are information necessary for the delivery person to definitely deliver the slip to the recipient, and must be printed on the first page of the slip. On the other hand, the transfer destination and amount of money in the 3rd and 4th lines are information that the third party does not want to know, and it is necessary to print on the second page inside the bag binding slip and not on the first page. It is.

  In this case, the print data on the first and second lines shown in FIG. 14A is printed on the back side and the number of printed pages is “2”, no hidden characters, and the print data on the third and fourth lines is printed on the back side and the number of printed pages. “1”, print page setting without hidden characters is performed, and printing is performed. As a result, printing as shown in FIG. 14B can be performed.

  In the embodiment described above, the print data reversal program for reversing the print data is stored in the ROM 23 in order to print from the back side, and the print data is reversed according to the information set in the print page information. Do. For example, when the information is an instruction to apply thermal energy to the back side of the thermal paper, the direction of character data or image data included in the print data is reversed. In this way, printing can be performed on a plurality of thermal paper sheets from the back side of the thermal paper.

  In addition, when the printer 2 of this portable terminal is dedicated for back side printing, it may not be necessary to invert the print data by devising a mechanical structure such as reversing the direction in which the head 37 is attached. is there.

  As described above, according to this embodiment, when printing is performed on the thermal paper with a bag as in the first embodiment, printing is applied to the head by printing on the first page of the table and printing on the second page of the bag. It is possible to perform appropriate printing by controlling the application time of the heat pulse to be performed.

  In the two embodiments described above, the number of pages to be printed is included in the printed page information. Instead, the same number of pages that are not printed is included in the printed page information. May be.

  Furthermore, in the two embodiments described above, print page data may be generated using a group of data obtained by combining both print data and print page information. Further, it may be inputted to the printer in the form of print page data synthesized from both the print data and the print page information. Furthermore, a configuration in which heating element driving data divided in time series such as f1 heat data and f2 heat data is input to the printer is also within the scope of the present invention.

  In the two embodiments described above, control is performed using two CPUs via the data buffer 24. However, the present invention is not limited to this, and serial communication, parallel communication, and wireless communication are not limited thereto. The control may be performed via, for example. In addition, the CPU that controls the portable terminal may directly control the printer. Further, a printer control hardware circuit that is directly or indirectly controlled by the main CPU that controls the mobile terminal as a whole may be used instead of the sub CPU. Furthermore, the printer may be built in the mobile terminal or may be independent.

  The present invention is not limited to a printer used for a portable terminal, but can also be applied to a printer used by connecting to a host device such as a personal computer, or a device used alone and having a printing function.

  In all the embodiments, any part of the control operation may be changed to be realized by a computer program or hardware.
