Tape print device

Abstract: The document data of a plurality of blocks (B1, B2, B3) are input and an auto size is set. After this, when a print key is operated, the data concerning the width of a tape is read out by a cassette distinction sensor (18). Then, the block number is calculated based on the document data stored in the text memory (41), and further, the linage of the first block is calculated. The print size is calculated based on the size table (TB) corresponding to the tape width data and the linage to be printed. The base line position of each print line is calculated based on the print size, the document data, the tape width data and the linage. The dot pattern data in each line which is formed based on the print size and the document data is developed into the print buffer based on the base line position. When the processing in each block is completed, the print processing is executed. Thus, various blocks of print on the tape may be set to different sizes.

Description: The present invention relates to a tape print device, and more particularly, to a tape print device capable of setting a character size according to the linage to be printed in each block, thereby a plurality of characters and symbols in each block are printed with the set character size. Conventionally, as described in US-A-5066152, a tape print device is capable of printing characters and symbols on a tape as a printing medium (for instance, the tape being about 10mm or 24mm in width). The tape print device is suitable for printing a file name on a tape to be pasted to the back cover of the file, for example. However, known tape print devices cannot print more than three lines. Moreover, when a tape print device prints two lines, the character size is fixed for two lines. That is, when the tape print device prints two lines, the tape print device recognizes the tape area to be printed as an upper line and a lower line by dividing the tape area into two parts in the longitudinal direction. The conventional tape print device prints characters and symbols with the fixed character size on the upper line and/or the lower line. Moreover, the conventional tape print device does not have a block key for setting the character column according to the linage to be printed. On the other hand, there is another tape print device having a function for printing characters and symbols in a plurality of lines on the tape. When the document data stored in a text memory is printed in the desired linage, for example, in two or three lines, the tape print device sets the character size fixed according to the linage to be printed. Suppose that there are some character columns comprising two lines or three lines. Then, there is an occasion when the tape print device has to continuously print these character columns as a character string. In this case, the tape print device sets the character size so as to be able to print characters and symbols in maximum linage. Therefore, even if the linage to be printed is changed, the tape print device prints characters and symbols with the fixed character size. Then, when the tape print device prints characters and symbols in minimum linage, the character size of the character column comprising the minimum linage is small with respect to the width of the tape. Therefore, there is a problem that the characters and symbols are not printed in a well-balanced arrangement on the tape. US 4,827,358 discloses a printer for printing on cut sheets in which the size of the characters is selected according to the size of the cut sheets and the amount of data to be printed. It is therefore an aim of the invention, as claimed, to provide a tape print device capable of setting a character size in each block according to the linage to be printed. The hereinafter described and illustrated embodiment of tape print device comprises: an input means for inputting characters, symbols and various commands; a print means including print heads for printing on a tape as a print medium with dot patterns; an input data storing means for storing the data of characters and symbols inputted from the input means; a print control means for making the dot pattern data based on the data of the input data storing means and for controlling the print means such that the print means executes the print operation; a block specifying means for grouping characters and symbols and for specifying the group as block data comprising one or a plurality of lines; and a size set means for receiving the data of characters and symbols stored in the input data storing means and the block data specified by the block specifying means, thereby setting the size of characters and symbols to print each block according to the linaqe of the block. In the tape print device the print control means creates the dot pattern data based on the data of characters and symbols stored in the input data storing means and controls the print means such that the print means executes the print operation. The block specifying means groups characters and symbols and specifies the group as block data comprising one or a plurality of lines. The size set means receive the data of characters and symbols stored in the input data storing means and the block data specified by the block specifying means, thereby setting the size of characters and symbols to print each block according to the linage of the block. Thus, the size of characters and symbols to be printed is set according to the linage in each block. Therefore, even if the linage of each block increases or decreases, characters and symbols are printed in each block in a well-balanced arrangement with respect to the width of the tape. The tape print device comprises the block specifying means and the size set means. The block specifying means groups characters and symbols and specifies the group as block data comprising one or a plurality of lines. The size set means automatically sets the size of characters and symbols in each block. That is, the size of characters and symbols to be printed is automatically set in each block according to the linage of the block. Therefore, even if the linage of each block increases or decreases, the characters and symbols are printed in each block in a well-balanced arrangement with respect to the width of the tape.

The present embodiment described below applies the present invention to a tape print device for English capable of printing a plurality of characters, such as alphabets, symbols, or the like, on a tape for printing (a tape as a print medium). As shown in Fig. 1, a keyboard 3 is disposed at the front of a main frame 2 of a tape print device 1. At the rear of the keyboard 3, a print mechanism PM is installed in the main frame 2. A liquid crystal display 22 capable of displaying characters and symbols is disposed at the rear of the keyboard 3. The keyboard 3 comprises character keys for inputting alphabets, figures and symbols, a space key, a new line key for starting a new line, a new block key for starting a new block, cursor movement keys for moving a cursor in leftward and rightward directions, a document making key for making document data, a format set key for setting a print format, a size set key for setting the size of characters to be printed, a type face set key for setting the type face of characters to be printed, a print key for executing a print operation, and a power supply key for turning on or off the power supply. Next, the print mechanism PM will be explained with reference to Fig. 2. A tape storage cassette CS having a substantially rectangular shape is detachably installed in the print mechanism PM. A tape spool 6, a ribbon supply spool 8, a take-up spool 9, a supply spool 11 and an adhering roller 12 are rotatably disposed in the tape storage cassette CS. A tape 5 for printing which is made of a transparent film, preferably being about 24mm in width, is wound on the tape spool 6. An ink ribbon 7 is wound on the ribbon supply spool 8. The take-up spool 9 takes up the ink ribbon 7. A dual sided adhesive tape 10 having the same width with the tape 5 for printing is wound on the supply spool 11 such that a releasable sheet faces the outside. The tape 5 for printing is superposed on and adhered to the dual sided adhesive tape 10 by the adhering roller 12. A thermal head 13 is disposed at a position where the tape 5 for printing is superposed on the dual sided adhesive tape 10. A platen roller 14 and a feeding roller 15 are rotatably supported on a supporter 16. The tape 5 for printing and the ink ribbon 7 are pressed to the thermal head 13 by the platen roller 14. The tape 5 for printing and the dual sided adhesive tape 10 are pressed to the adhering roller 12 by the feeding roller 15. A heat-generating element group preferably having 128 heat-generating elements arranged in a vertical direction is provided on the thermal head 13. Therefore, when a tape feeding motor 24 (see Fig. 3) is driven so as to rotate in a predetermined rotating direction, the adhering roller 12 and the take-up spool 9 are driven so as to rotate in a predetermined rotating direction in synchronization with each other. Further, when the heat-generating element group is turned on by an electric current, characters are printed on the tape 5 for printing by a plurality of dot lines. After this, the tape 5 for printing is adhered to the dual sided adhesive tape 10 and is discharged in a tape feeding direction A (see Japanese Laid-Open Patent Publication No. 2-106555). A cassette distinction member 17 for indicating the kind of the tape storage cassette CS, that is, for indicating the width of the tape 5 for printing stored in the tape storage cassette CS, is provided on the bottom wall of the tape storage cassette CS. A cassette distinction sensor 18 (see Fig. 3) comprising a photo interrupter for detecting a projection splinter (not shown) formed on the cassette distinction member 17 is provided on the main frame 2. Therefore, the width of the tape 5 for printing can be distinguished based on the distinction signal from the cassette distinction sensor 18. There may, for example be five kinds of tape storage cassettes CS. Each tape storage cassette CS stores a tape 5 for printing having 6mm, 9mm, 12mm, 18mm or 24mm widths, for example. Next, the control system of the tape print device 1 as constructed as shown in the block diagram of Fig. 3 is described. A keyboard 3, the cassette distinction sensor 18, a driving circuit 21 for a warning buzzer 20, a display controller (LCDC) 23 having a RAM for displaying data, thereby outputting display data into a liquid display (LCD) 22, a driving circuit 25 for driving the thermal head 13 and a driving circuit 26 for driving the tape feeding motor 24 are respectively connected to an input/output interface 27 of a control device C. The control device C comprises a CPU 29, the input/output interface 27 which is connected to the CPU 29 through a bus 28, such as a data bus, a CGROM 30, ROMs 31, 32 and a RAM 40. The CGROM (pattern data memory) 30 stores dot pattern data for displaying each of a plurality of characters such that the dot pattern data corresponds to code data for each character. The ROM (outline data memory) 31 stores outline data such that the outline data corresponds to the code data for each character. The outline data is used for regulating the outline of each character in order to print each character. Besides, the outline data for each character are classified into a type face, such as Gothic style, Mincho style, or the like. Moreover, the outline data includes various sizes in the vertical direction and in the horizontal direction of the print image. The ROM 32 stores a display drive control program, an image develop processing control program, a print drive control program and a control program. The display drive program is used for controlling a display controller 23 when characters, such as alphabets, figures, symbols, or the like are input from the keyboard 3. At this time, each character is made to correspond to the code data. The image develop processing control program is used for changing the outline data corresponding to each code data in a text memory 41 into the dot pattern data for printing, thereby developing a print buffer 47. The print drive control program is used for reading out in sequence the data in the print buffer 47, and driving the thermal head 13 and the tape feeding motor 24. The control program is used for controlling a tape print operation of the present invention to be described later. Further, the ROM 32 stores size tables TB for setting the character size. Each size table TB corresponds to each tape 5 for printing of the five kinds of tapes. According to the size table TB, the character size is set based on the linage to be printed such that characters can be printed on the tape 5 for printing. For example, as shown in Fig. 4, according to the size table TB (24) for a tape being 24mm in width, the character size is set for each linage from 1 to 5 such that characters can be printed on the tape. Since other size tables TB are similar to the size table TB (24), illustrations of other tables are omitted. The text memory 41 of the ROM 40 stores the code data of the characters and symbols inputted from the keyboard 3 as document data. A print format memory 42 stores a plurality of print format information about the character size data PZ, the type face data, or the like. A block number counter 43 stores the block number N of the document data stored in the text memory 41. A character size memory 44 stores the size data PZ. A linage memory 45 stores the linage L of the block document data. A work memory 46 stores the block document data which is read out. The print buffer 47 stores the dot pattern data of a plurality of characters and symbols, which are developed in the image. Therefore, the print buffer 47 comprises a memory capacity for 128 bits (16 bytes) corresponding to 128 dots in the vertical direction (dot column direction) and a predetermined bits for 50 characters to the horizontal direction, thereby the dot pattern data of one or a plurality of lines is developed. A flag memory 48 stores flag data of an auto flag AF which is set such that the data is to be "1" when the auto size for characters is selected. Further, the ROM 40 has a buffer which temporarily stores the result calculated by the CPU 40, a counter and a pointer. Next, the routine of the tape print control which is executed by the control device C of the tape print device 1 will be explained with reference to the flowchart of Fig. 5. Si (i=10, 30, 60....) corresponds to each step in the figure. When the power supply is started by way of a power supply key, the control operation is started. Next, document making keys are operated. After this, document data input/editing processing for inputting the code data as the document data is executed. The code data corresponds to the character keys, the space key, the new line key and the new block key which are operated in S10. Next, the processing for setting the print format such as the character size, the type face, the embroidery specification, or the like, is executed by way of a format set key (S30). That is, the print format set processing comprises a plurality of format set processings, such as the character size set processing, the type face set processing, or the like. Next, the dot pattern data making processing is executed by way of the print key (S60). The dot pattern data making processing develops the dot pattern data for printing which is used for printing the document data, into the print buffer 47. The print processing for outputting the dot pattern data read out from the print buffer 47, into the print mechanism PM, is executed in S90. Next, the routine of the character size set processing control of the print format set processing will be explained with reference to the flowchart of Fig. 6. When the size set key is operated, the character size set processing control is started. First, a character size set screen is displayed on the display 22 (S31). For example, as shown in Fig. 9, each character size is displayed in point value. These point values respectively correspond to numbers 1-6. Further, the auto size is displayed as a number 7. Next, the figure key for selecting the character size is operated (S32, S33: Yes). Further, when an arbitrary character size other than the auto size is selected (S34: No), the auto size flag AF is reset (S36), and the selected size data PZ is stored in the character size memory 44 (S37). Then, the control is completed, and the processing returns to the tape print control. However, when the auto size is selected (S34: Yes), the auto size flag AF is set, and thereby the auto size mode is set (S35). Then, the processing returns to the tape print control. Next, the routine of the dot pattern data creating processing control for printing which is executed in step S60 will be explained with reference to Figs. 7A and 7B. At this time, as shown in Fig. 8, the text memory 41 stores in sequence the document data of the first block, the second block and the third block. New block code input by way of the new block key is stored between each block, and the character data for printing two lines is stored as the document data of the first block. The character data for printing one line is stored as the document data of the second block. The character data for printing five lines is stored as the document data of the third block (see Fig. 10). When the control is started, first the data concerning the width of the tape is read out based on the distinction signal from the cassette distinction sensor 18 (S61). When the document data to be printed is stored in the text memory 41 (S62: Yes), the block number N is calculated based on the number of the new block codes (S63). The block number N is stored in the block number counter 43 as the block number BC (S64). Next, when the auto size mode is set (S65: Yes), the block document data of the first block is read out and stored in the work memory 46 (S66). For example, the first block document data comprising the first line "WEAK" and the second line "POINT", is stored in the work memory 46 from the text memory 41 shown in Fig. 8. Next, the linage L of the block document data is calculated based on the number of new codes and new block codes, and is stored in the linage memory 45 (S67). Next, the size data is calculated as the auto size AP based on the size table TB corresponding to the tape width data and the linage L. That is, according to the size data, characters can be printed on the tape for printing 5. The auto size AP is stored in the size memory 44 (S68). Suppose that the width of the tape for printing 5 is 24mm and the linage to be printed is 2. Then, as shown in Fig. 4, 20 points is calculated from the size table TB as the auto size AP. The base line position of each print line is calculated based on the auto size AP, the tape width data, the linage L and the outline data (S69). Next, the code data of each line to be printed is read out from the work memory 46 based on the base line position. While the outline data is modified or reduced, the dot pattern data for printing is formed based on the outline data. Then, the dot pattern data is developed in sequence into the print buffer 47 (S70), and the block number BC is decremented at one (S71). When the block number BC is not "0", that is, when the following block document data is stored in the text memory 41 (S72: No), the processing returns to step S65. The dot pattern data for the following block document data are formed in sequence and are developed into the print buffer 47. When the dot pattern data for all block document data stored in the text memory 41 are formed (S72: Yes), the processing is completed. After this, the print processing is executed based on the dot pattern data stored in the print buffer 47 (S90). Similarly, the document data of the second block comprising one line and the document data of the third block comprising five lines are read out in sequence from the text memory shown in Fig. 8. The dot pattern data for each document data is formed in sequence so as to get the auto size AP calculated in each block and stored in the print buffer 47. Thus, the print processing is completed. As shown in Fig. 10, each character size of the first block B1, of the second block B2 and of the third block B3 are respectively set based on the linage L in each block automatically. Therefore, even if the linage L is increased or decreased, the characters and symbols in each block B1-B3 can be printed in a well-balanced arrangement on the tape. Further, the characters and symbols are printed in the same size in each block B1-B3. Therefore, the characters and symbols can be printed in a well-balanced arrangement in each block B1-B3. On the other hand, when the auto size mode is not selected (S65: No), the block document data of the first block is read out and the linage L of the block document data is calculated in a similar manner as described above in steps S66, S67 (S73, S74). The height of the character in each line is added up based on the size data PZ stored in the character size memory 44, the tape width data, the linage L and the outline data. When the total height of the characters of each line is smaller than the height of the area to be printed on the tape 5 for printing, that is, when all the characters can be printed on the tape (S75: Yes), the processing goes to the step S69. Then, the dot pattern for the document data in each block is formed in sequence and stored in the print buffer 47. On the other hand, if the control processing is started and the document data to be printed is not stored in the text memory 41 (S62: No), or the total height of the character of each line is larger than the height of area to be printed on the tape 5 for printing, that is, when all the characters can not be printed on the tape (S75: No), a buzzer 20 makes a warning sound (S76) and the processing goes to step S10 for the tape print control. The linage and size stored in the size table TB as described above is only one example out of many possibilities. Any linage and various sizes may be set. Moreover, various tape 5 for printing other than a tape for printing being 24mm in width may be used. The present invention can also be applied to various tape print devices, such as a tape print device which stores the print image comprising the characters and symbols as dot pattern data. It will be understood by those skilled in the art that various changes and modifications can be made therein without departing from the scope of the invention as defined in the appended claims.
