Character information processor for printing characters

Abstract: A character information processor which can be applied to a tape printing device. The character information processor is provided with a read-only memory in which a table containing the levels of alternatives of a menu hierarchical structure set correspondingly to each edition function is stored. When an edition level is selected by an operator by keying, only edition operations, which are available at the selected edition level, are displayed on the screen of a display unit as choices. An example of the function of editing a character string is a function for enabling the restoration of a text, on which an edition operation such as an input operation and a deleting operation has been once performed. This function is implemented by providing a restoration buffer in the processor and by storing a character or a character string, on which an operation is performed, and a cause-for-restoration parameter representing a kind of an operation in the processor each time when an operation such as an input and a deletion is performed, and by performing a restoration operation according to the cause-for-restoration parameter. Further, regarding an operation of editing a printing layout, the processor has an operation of performing a text alignment by converting a full-size space, which is inputted by keying similarly as in the case of an ordinary character, into a half-size space to be treated as a space of a size, which is half of the size of a full-size character, when printing. Moreover, regarding an operation of editing ruled lines, the processor has the following edition function to be performed when printing two adjoining or adjacent paragraphs in such a way that one side of a ruled-line frame pattern for enclosing one of the two paragraphs overlaps with one side of a ruled-line frame pattern for enclosing the other of the two paragraphs. Namely, this edition function is to generate a connecting ruled-line pattern preliminarily prepared as a frame pattern for an overlap between the two ruled-line frame patterns in the case that the two ruled-line frame patterns have a same attribute. This facilitates an operation of designating an ruled-line frame pattern and prevents ill effects of the double printing of a same ruled line.

Description: The present invention relates to a character information processor for printing or transferring one or more lines of input characters onto a printing medium. The present invention can be applied to, for example, a device for printing characters on tape (hereunder referred to simply as a tape printing device), which uses tape as a printing medium, and a seal making device in which a transfer medium (or printing medium) is the face of a carved seal. In the case of a conventional tape printing device for printing a title on the spine or back of a binder (namely, a detachable cover with rings or clamps) or on a "title label" to be attached to a cassette for use in a video cassette recorder (VCR) or in a video tape recorder (VTR), input characters entered by using keys such as alphanumeric keys are printed on the other side of the adhesive-backed tape by performing, for example, a thermal transfer printing to thereby produce an objective printed tape. In this conventional tape printing device, the keys for entering information representing characters are placed on a console panel. Thus a desired sequence of characters can be inputted by operating such keys for entering information representing characters. Moreover, this conventional tape printing device is formed in such a manner that tape can be fed through a tape discharging slot by driving a tape feeding mechanism. Furthermore, a printing mechanism, which is constituted by a thermal print head, and a tape cutting mechanism are placed in series in this passage for tape. When a print instruction key is operated, a control means of the tape printing device controls and causes the tape feeding mechanism to feed the tape at a predetermined speed. The control means further controls and causes a print station to print preliminarily inputted characters on the fed tape. Moreover, upon completion of printing of a sequence of the characters, the control means of the tape printing device continuously controls and causes the tape feeding mechanism to feed the tape until a printed part of the tape goes out of the device. When the printed part of the tape goes out of the device, the control means causes the tape feeding mechanism to make the tape stop running. Further, after the tape stops running, a user operates the tape cutting mechanism to thereby obtain a custom label, on which the sequence of desired characters are printed. Even in the case of the aforementioned conventional tape printing device, a sequence of desired characters can be inputted and edited by performing an input operation method similar to a method employed in a character information processor such as what is called a word processor. However, in the cases of employing the writing systems of languages, each of which uses many kinds of characters, for example, in the cases of the Japanese and Chinese writing systems, a large number of keys are necessary for directly inputting such characters to the device. Thus, the Japanese characters and the Chinese characters are preliminarily stored in a character-generator memory (hereunder referred to simply as a CG-memory) correspondingly to the combinations of letters of the alphabet of English. Further, the device is endowed with a character conversion function by which a Japanese or Chinese character corresponding to an inputted combination of keyed letters of the alphabet of English is read from the CG-memory. Thereby, the number of necessary keys is reduced. This character conversion function is applied not only to Japanese and Chinese but can be applied to a case where various kinds of symbols, for example, double-wide symbols respectively representing marks such as an arrow, a heart and a spade are stored in the CG-memory (sometimes, such symbols are generically named "full-size character" or "two-byte character"). In the case of converting an input combination of characters of the alphabet of English to a Japanese character, some conventional tape printing devices employ a two-stage conversion method by which the input combination of characters of the alphabet of English is first converted to a set of kana characters of the alphabet of Japanese and subsequently, the set of kana characters are further converted into a kanji character. This method is named "kana-kanji conversion or translation". Kana characters are inputted correspondingly to the pronunciation of a kanji character. In the case where input keys correspond to an English alphabetic code, an input code corresponding to the Roman alphabet is first converted into a kana character code and thereafter, this kana character code is further converted into a kanji character code through the kana-kanji conversion. The conventional tape printing device, however, is small in size in comparison with ordinary personal computers, electronic typewriters and word processors. Thus, the console panel of the conventional tape printing device has a small area, and a liquid crystal display, on the screen of which only several lines of characters can be displayed, is mounted on a display unit thereof. Further, many people, who have inexperienced in using word processors or the like and are unfamiliar with character inputting operations, use the conventional tape printing device. The conventional tape printing device, therefore, has only a small number of kinds of the functions of editing a sequence of characters, namely, the character editing function of the conventional tape printing device are limited. Thus, the conventional tape printing device does not have, for example, the functions of moving, correcting and reconverting a sequence of characters. Here, the function of moving a sequence of characters (namely, a character string) is defined as that of taking in the character string to be moved after depressing a moving key, and thereafter moving the character string to a designated destination. Further, the function of correcting a sequence of characters is defined as that of automatically deleting a sequence of characters in a designated range to be corrected after depressing a correcting key, and thereafter automatically inserting another sequence of characters inputted until depressing the correcting key, as a substitute for the deleted characters. Moreover, the function of reconverting a sequence of characters is defined as that of bringing back a designated sequence of (definitely) determined characters into an indeterminate state. EP-A-0 577 247 describes a tape printing device including a control portion. The control portion processes dot data to be printed based on a coded text data. EP-A-0 567 233 relates to a tape printing apparatus capable printing underlines or frames. The apparatus comprises a dot pattern data memory to store dot data associated with input characters and a RAM for storing temporary results of various computations performed by a CPU. The RAM contains various memory regions including a text memory for storing text data and flags which are set in accordance with a local frame, local underline, global frame and a global underline section. Based on the set flag, a corresponding sub-routine for generating the dot data is initiated. The generated dot data are transferred to a print buffer and the stored data are printed onto a tape via a thermal head. The conventional tape printing device further has the function of modifying or embellishing characters and the function of putting a border or frame (namely, a ruled-line frame or enclosure) around a character string. Thereby, the conventional tape printing device can produce various labels. Meanwhile, the latest tape printing device comes to be able to perform a multi-line printing (namely, to print, for instance, four lines at the maximum simultaneously). Thus, recently, there has been a user request for the printing of a table. Further, there has been already proposed a tape printing device which can fulfill the user request. For example, when a label, on which a table of FIG. 9 (A) is printed, is formed, in the case of the conventional tape printing device, a ruled-line border is designated correspondingly to each of character strings "FIRST GROUP", "SUZUKI××", "TAKAHASHI○○○" and "SATOHΔΔ". The conventional tape printing device, however, has drawbacks in that it is necessary for printing a table to designate a ruled-line border correspondingly to each of character strings to be inserted in the ruled-line frame of the table and in that thus the operation of making out the table is complex. Moreover, the conventional tape printing device further has a drawback in that a same ruled line is printed doubly (or twice) in an overlap among the ruled-line borders respectively put around the character strings and thus each part of the ruled lines, which is doubly printed, becomes thicker than the peripheral ruled-lines of the table. Furthermore, the conventional tape printing device has additional drawbacks in that if a plurality of character strings belonging to a same column of a table are different in length from one another and moreover, a ruled-line frame is designated correspondingly to and is put around each of the plurality of character strings without taking-remedial steps, an incongruent table is formed as illustrated in FIG. 9(B), and in that it is necessary for avoiding making such an incongruent table to designate a ruled-line frame correspondingly to each of the plurality of character strings after suitably inserting spaces into the character strings in such a manner that the plurality of character strings belonging to the same column of the table become of a same length, with the result that the operation of making the table becomes complex. Further, such a problem is caused not only by the tape printing device but also by a character information processor for processing an object to be printed or transferred, which has the considerably high degree of freedom of attributes such as character pitches, character sizes and margins. For example, a similar problem crops up in, for example, a seal making device adapted to use a resin, whose part is hardened upon receiving ultraviolet radiation and left over after the other part is removed by the action of a predetermined fluid, as the face of a seal to be carved by being irradiated with light rays corresponding to input characters (incidentally, this is a transferring operation, and in the specification of the instant application, the term "printing" includes the concept of "transferring"). The present invention is accomplished in view of the aforementioned drawbacks and problems of the conventional device. Furthermore, still another object of the present invention is to provide a character information processor, by which an operation of making a table can be easily performed and a table of high printing quality can be obtained. This is achieved by the features of claims 1 and 2 for a character information processor and by the features of claims 4 and 5 for a method of processing character information. Moreover, regarding an operation of editing ruled lines, the processor has the following edition function to be performed when printing two adjoining (or adjacent) paragraphs in such a way that one side of a ruled-line frame pattern for enclosing one of the two paragraphs overlaps with one side of a ruled-line frame pattern for enclosing the other of the two paragraphs. Namely, this edition function is to generate a connecting ruled-line pattern preliminarily prepared as a frame pattern for an overlap between the two ruled-line enclosure or enclosing patterns in the case that the two ruled-line frame patterns have a same attribute. This facilitates an operation of designating an ruled-line frame (pattern) and prevents ill effects of the double printing of a same ruled line. Other features, objects and advantages of the present invention will become apparent from the following description of preferred embodiments with reference to the drawings in which like reference characters designate like or corresponding parts throughout several views, and in which: FIG. 1 is an electrical functional block diagram for illustrating a tape printing device embodying the present invention (namely, an embodiment of the present invention); FIG. 2 is a diagram for illustrating the structures of a tape cartridge and tape used in the tape printing device embodying the present invention; FIGS. 3 (A) to 3 (C) are diagrams for illustrating the concept of a paragraph; FIGS. 4 (A1), 4 (A2), 4 (A3), 4 (A4), 4 (B) and (C) are diagrams for illustrating examples of frame patterns used in the embodiment of the present invention; FIG. 5 is a flowchart for illustrating an operation of modifying the style of a paragraph used in the embodiment of the present invention; FIG. 6 is a flowchart for illustrating a printing operation of printing ruled lines, which is performed by the embodiment of the present invention; FIG. 7 is a diagram for illustrating the printing operation of the embodiment of the present invention supplementally; FIGS. 8 (A) to 8 (C) are diagrams for illustrating a pattern for making a table, which is used by the embodiment of the present invention; FIGS. 9(A) and 9 (B) are diagrams for illustrating the drawbacks or problems of the conventional method for making a table; FIGS. 10 (A) to 10(E) are diagrams for illustrating a menu hierarchical structure of text formats; and FIGS. 11 (A) and 11 (B) are flowcharts for illustrating an operation of selecting one of choices to be performed in the embodiment of the present invention. Hereinafter, a preferred embodiment of the present invention (namely, a tape printing device embodying the present invention) will be described in detail by referring to the accompanying drawings. This tape printing device has various character edition functions. First, the entire configuration of the tape printing device for implementing such edition functions will be described hereinbelow by referring to an electrical functional block diagram of FIG. 1 and to FIG. 2 which is a diagram for illustrating a tape cartridge. As illustrated in FIG. 1, this tape printing device mainly consists of an input portion 10, a control portion 20 and an output portion 30, similarly as in the cases of other character information processors. The control portion 20 performs operations according to information sent from the input portion 10 and to the current processing stage. Further, a result of the operation or the like is outputted from the output portion 30 by displaying or printing thereof. The input portion 10 consists mainly of a key entry portion 11, which has a depression key and what is called a dial key and so forth, and a width-of-tape detecting sensor 12 (incidentally, the detailed description of the structure of the input portion 10 is omitted for simplicity of description). The key entry portion 11 is operative to generate character code data and various kinds of control data, which are given to the control portion 20. The width-of-tape detecting sensor 12 is operative to detect the width of tape loaded in the tape printing device and to give width-of-tape information to the control portion 20. Practically, tape is enclosed in a tape cartridge 2 in which physical identification elements, such as holes, for defining or determining the width of tape are provided. The width-of-tape detecting sensor 12 reads (or detects) the physical identification elements and outputs the width-of-tape information. As shown in FIG. 2, both of a sheet of transferring tape 1a and a sheet of transferred tape 1b are wound on a reel in the tape cartridge 2. In the transferred tape 1b, an adhesive layer 1d is formed on a base layer 1c. Further, a cover layer 1e, which is peeled off when the tape 1b is stuck, is loosely glued to this adhesive layer 1d. A surface of the cover layer 1e, which faces the adhesive layer 1d, is covered with a coating so as to facilitate the peeling of the adhesive layer. On the other hand, a surface of the base layer 1f of the transferring tape 1a, which faces the transferred tape 1b, is covered with transferring ink 1g. After selectively heated by a thermal print head 32, the transferring ink 1g of the tape 1 is transferred onto the base layer 1c. Thus, as shown in a lower portion of FIG. 2, characters are formed on a surface of the transferred tape 1b by peeling the transferring tape 1a therefrom. Colored plastic tape, which is molten by heat, other than the aforementioned two-layer tape may be used as the transferring tape 1a. Further, an example of such plastic tape is tape for use in a printer employed as a printing device of a common or general personal computer system. In the case of this embodiment, for example, a key dedicated to the issuance of a command to perform a restoration function (to be described later) is provided in the key entry portion 11. The output portion 30 is composed of print elements and display elements. A tape/ribbon feeding motor 31, which may consist of, for example, a stepping motor, is operative to feed a tape or an ink ribbon (not shown) of FIG. 2 loaded in the tape printing device to a predetermined printing position or to the outside thereof. Thermal print head 32 is operative to print characters on the tape running thereon by performing what is called a thermal transfer printing. For example, the thermal print head 32 can print a maximum of 128 dots simultaneously. The tape/ribbon feeding motor 31 and the thermal print head 32 are driven by the motor drive circuit 33 and the head drive circuit 34, respectively, under the control of the control portion 20. The printed tape is cut by external forces exerted by, for example, a user or a cutter (not shown) driven by a motor (not shown). In the case of this tape printing device embodying the present invention, a LCD 35 is provided therein as a display portion. This LCD 35 is driven by a display drive circuit 36 under the control of the control portion 20 and is operative to display an input character string, various kinds of attribute information and so forth directly on the screen (not shown) thereof and is also operative to turn on indicators on the screen thereof, which indicators respectively correspond to items of attributes represented by characters printed on the surface of the circumference portion (not shown) of the screen thereof. The control portion 20 is constituted by, for example, a microcomputer. Further, as shown in this figure, a central processing unit (CPU) 21, a read-only memory (ROM) 22, a random access memory (RAM) 23, a character-generator ROM (CG-ROM) 24, an input interface portion 25 and an output interface portion 26 are connected with one another through a system bus 27. Moreover, various processing programs and inalterable data (or constant data) such as kana-kanji translation dictionary data are stored in the ROM 22. On the other hand, the RAM 23 is used as a work memory and is also operative to store inalterable data inputted by a user. Incidentally, when the power is turned off, the contents of the RAM 23 is backed up. The processing programs and inalterable data stored in the ROM 22, as well as the data stored in the RAM 23, will be described in detail in the aftermentioned description. Incidentally, a processing program 22a for inputting and editing characters is stored in the ROM 22. Further, when executing the processing program 22, a work area to be used for the execution of the processing program is suitably formed or preliminarily established in the RAM 23 and is utilized. Furthermore, the CG-ROM 24 stores information (hereunder sometimes referred to as font information) on the fonts of letters, digits, or other symbols (hereunder referred to simply as characters), which are supported by the tape printing device embodying the present invention. When code data specifying a character is given (incidentally, the "code data" will be sometimes referred to simply as "character" hereinafter), font information corresponding to the character is outputted from the CG-ROM 24. Here, note that either outline fonts or bitmap fonts may be employed as the fonts which are designated by the font information stored in the CG-ROM 24. The input interface portion 25 is operative to provide the interface between the input portion 10 and the control portion 20. Further, the output interface portion 26 is operative to provide the interface between the output portion 30 and the control portion 20. The CPU 21 processes an input signal sent from the input portion 10 and executes a processing program, which is stored in the ROM 22 and corresponds to a current stage of the processing, by utilizing the work area established in the RAM 23 and by suitably using the inalterable data stored in the ROM 22 and in the RAM 23, if necessary. Moreover, the CPU 21 causes the LCD 35 to display information representing the situation or results of the processing on the screen thereof and further causes the thermal print head to print such information on tape (not shown). Frame Forming Edition Functions The tape printing device of the first embodiment has functions of generating and editing ruled lines for enclosing a character string or a set of character strings (namely, a paragraph) in addition to the aforementioned edition functions to be performed when inputting a character string. Hereinafter, the concept of a paragraph will be first described. Then, borders, tabular frames and rounded tabular frames (namely, enclosing patterns) will be described by referring to the accompanying drawings. A paragraph is defined herein as a set of printed lines or rows, which are arranged in the direction of width of tape (incidentally, a single printed line is included in the concept of a paragraph). Further, a paragraph may be a unit, for which various printing effects (sometimes referred to as paragraph styles), such as the number of lines and the character sizes employed for each line, are designated. A label is formed by arranging one or more paragraphs in sequence in the longitudinal direction of tape and printing the paragraphs. FIGS. 3 (A), 3 (B) and 3 (C) illustrate a label constituted by a single paragraph, a label consisting of two paragraphs and a label composed of three paragraphs, respectively. A border, a tabular frame or a rounded tabular frame can be designated for each of such paragraphs. As illustrated in FIGS. 4 (A1) and 4 (A2), borders are nearly rectangular enclosing patterns, each of which encloses or surrounds all of character strings of a paragraph (incidentally, the frame of FIG. 4(A1) is called "a bold frame", and the frame of FIG. 4(A2) is called "a bold rounded frame"). Hereunder, the left side, the right side, the top side and the bottom side of a border enclosing all of character strings of a paragraph will be referred to as "a front (ruled) line", "a rear (ruled) line", "a top (ruled) line" and "a bottom (ruled) line", respectively. Moreover, ruled lines extending laterally will be referred to as "lateral (ruled) lines". The first embodiment provides borders having front and rear ruled lines to which pictorial symbols are applied, as illustrated in FIGS. 4 (A3) and 4 (A4). Furthermore, this embodiment provides a full-size border having relatively large pictorial symbols applied to the front and rear ruled lines thereof and a half-size border having relatively small pictorial symbols applied to the front and rear ruled lines thereof. Incidentally, in the cases of borders of FIGS. 4(A1) and 4(A2), front and rear ruled lines are handled similarly as such pictorial symbols. A tabular frame is defined as an enclosing pattern consisting of front, rear, top and bottom ruled lines, which enclose all of character strings of a paragraph, and a lateral ruled line (hereunder referred to as an interlinear ruled line) drawn between adjacent lines of characters, as illustrated in FIG. 4(B). The concept of this tabular frame of this embodiment is introduced for the first time in the art of the character information processor. A rounded tabular frame is an enclosing pattern obtained by rounding the corners where pairs of the front, rear, top and bottom ruled lines of a tabular frame as illustrated in FIG. 4 (B) join, as illustrated in FIG. 4 (C). In the case of this embodiment, a table can be made by designating a border, a tabular frame or a rounded tabular frame for each paragraph. When making a table, if a paragraph consists of, for example, characters of three lines of different lengths, the distance between the front and rear ruled lines is determined on the basis of the longest line of characters. Operation of Modifying Paragraph Style: Next, an operation of modifying a paragraph style, especially, an operation of designating a border, a tabular frame or a rounded tabular frame will be described hereinafter by referring to a flowchart of FIG. 13. Here, attributes concerning a paragraph style are, for instance, whether or not a border, a tabular frame or a rounded tabular frame is added to a paragraph, combinations of character sizes used in each line, vertical writing/horizontal writing, and a layout of characters in a paragraph (for example, center justification, front or left justification, full justification or the like). Further, a user can modify the style of a paragraph by first positioning the cursor at a paragraph having a style to be modified, and next designating the modification of a paragraph style by use of the key entry portion 11. At that time, the CPU 21 starts executing a program of FIG. 5 for modifying a paragraph style, which is stored in the ROM 22. Further, in step 500, the CPU 21 first takes in or fetches a style to be modified, which has been established for a paragraph and stored in the text area. Then, the CPU 21 copies this style onto a style fetching buffer. Subsequently, the CPU 21 causes the LCD in step 501 to display an initial setting screen. Here, the setting screen is constituted by a title, which represents a kind of an attribute, and a candidate for the title (namely, the kind of an attribute) to be set (incidentally, at the time of initially setting, a default value for the title). If no kind of an attribute (namely, the title) is selected, the item (or option) of the title is displayed as being in a ready state for selection (namely, a selection waiting state). If a title is selected, the item of the title is displayed as being in an already selected state. Incidentally, in an initial setting screen, for example, a combination of character sizes employed by each line is displayed. Moreover, in addition to attributes concerning the style, a title representing the termination of designation (namely, indicating that there is no candidate to be set) is provided in the device. When the item of the title is displayed as being in a ready state for selection, the CPU 21 identifies an operated key in step 502. When a candidate alteration key (for instance, the cursor key) is operated, the CPU 21 causes the LCD in step 503 to change the title (and alternatives associated therewith) displayed on the screen thereof into another title (and corresponding alternatives). Subsequently, the CPU 21 is returned to step 502 for identification. In contrast, when the selection key is operated, an operation of fetching a value set according to the title displayed at that time or a termination operation is performed. If the selection key is operated when a title "FRAME·TABLE" corresponding to an attribute to be selected for determining whether or not a border, a tabular frame or a rounded tabular frame is added to a paragraph is displayed, the CPU 21 causes the LCD in step 504 to display values set until that time as being in a ready state for selection. Subsequently, the CPU 21 identifies the operated key in step 505. Incidentally, a default value for the title "FRAME·TABLE" is "NONE" which indicates that a border, a tabular frame and so on are not added to a paragraph. Further, values other than "NONE" are displayed by using a number, which represents a kind such as a border, a tabular frame and a rounded tabular frame, and dot patterns (or characters) representing front and rear ruled lines. When the candidate alteration key is operated, in step 506, the CPU 21 changes the candidate for the set value into another candidate and further causes the LCD to display the new candidate. Then, the CPU 21 is returned to step 505. When the selection key is operated, the CPU 21 fetches a currently displayed candidate for the set value in step 507. Subsequently, the CPU 21 causes the LCD to display the next title (for example, "FINISH DESIGNATION") according to a predetermined displaying order. Then, the CPU 21 is returned to step 502. Incidentally, if a set value other than "NONE" is displayed as being in a ready state for selection at that time, a display indicator for representing an on- or off-state of such an attribute is blinked. When the selection of a set value other than "NONE" is definitely determined, the display indicator is turned on. If the selection key is operated when the character string "FINISH DESIGNATION" is displayed, the CPU 21 causes the text area in step 509 to store the paragraph style, which has been held in the style fetching buffer, in a style area thereof accompanying a sentence of the paragraph having the style to be modified. Then, the CPU 21 causes the LCD in step 510 to display the character input screen at the time of instructing the modification of the paragraph style. Thus, the CPU 21 finishes the operation of modifying the paragraph style and is returned to a ready state for inputting character. When the selection key is operated during a title representing another attribute such as a combination of character sizes used in each line, vertical writing/horizontal writing, and a layout of characters in a paragraph (for example, center justification, front or left justification, full justification or the like) , the CPU executes a subroutine SUB corresponding to the selected attribute. An operation to be performed at that time is almost similar to the operation of selecting the set value concerning the attribute to be selected for determining whether or not a border, a tabular frame or a rounded tabular frame is added to a paragraph. In this way, the CPU 21 can set a value, which represents whether or not a border, a tabular frame or a rounded tabular frame is added to a paragraph, for each paragraph. Printing Operations: Next, printing operations (especially, a process of adding an enclosing pattern such as a border, a tabular frame and a rounded tabular frame) will be described hereinbelow by referring to a schematic process flowchart of FIG. 6 and a diagram of FIG. 7 for illustrating a printing operation. Incidentally, when it is requested to display a printed image, an operation similar to that of FIG. 14 (namely, an operation of loading a dot pattern into the print buffer) is performed. If a printing key is operated in a state in which a character string is displayed on the screen of the LCD 35, the CPU 21 starts executing a processing program of FIG. 6. First, in step 620, the CPU 21 performs an initial process of preliminarily determining values needed for printing and recognizing the number N of paragraphs. Moreover, the CPU 21 sets a parameter n representing the number of printed paragraphs at 1. Then, the CPU 21 advances to step 621. Incidentally, the initial process, for example, the fundamental length of each of front and rear ruled lines of a border, a tabular frame or a rounded tabular frame to be used, and the size of an inter-paragraph space (namely, the distance between adjacent paragraphs) are determined according to the width of tape detected by the width-of-tape detecting sensor 12. The CPU 21 judges in step 621 whether a border, a tabular frame or a rounded tabular frame is added to a paragraph corresponding to the value of the parameter n. If not, the CPU 21 instructs to print character strings of the paragraph in accordance with the style thereof (exclusive of a border, a tabular frame and a rounded tabular frame) in step 622. Thereafter, in step 623, the CPU 21 checks whether or not the printing of the last paragraph has been finished. Then, in step 624, the CPU 21 increments the parameter n by 1. Subsequently, the CPU 21 is returned to step 621. Incidentally, the operation of printing the character string in step 622 includes that of printing a half-size space and forming the front space (in the case where the paragraph concerned is a first paragraph) as and further includes that of securing the distance between adjacent paragraphs. Moreover, when completing the printing of the last paragraph, the operation of forming the rear space (not shown) is performed. Thus, the device finishes a sequence of printing operations. If a border, a tabular frame or a rounded tabular frame should be added to the paragraph corresponding to the value of the parameter n, the CPU 21 judges in step 625 whether the rear ruled line of the frame enclosing the immediately preceding paragraph is printed and whether a connecting ruled line (as drawn in the portion between the positions F and G of FIG. 7) is printed as this rear ruled line. If a connecting ruled line is printed as such a rear ruled line, the CPU 21 determines in step 626 that the front ruled line of the frame enclosing the paragraph corresponding to the value of the parameter n has been printed. In contrast, if such a rear ruled line is not a printed connecting (ruled) line, the CPU 21 instructs in step 627 to print (the dot pattern representing) the front ruled line (as drawn in the portion between the positions B and C of FIG. 7) of a border, a tabular frame or a rounded tabular frame to be added to the paragraph corresponding to the value of the parameter n. Thereafter, the CPU 21 instructs in step 628 to print the character strings of the paragraph concerned and the lateral ruled lines (namely, the top and bottom ruled lines and interlinear ruled lines, if any). Incidentally, as illustrated in FIG. 7, a space portion having a width equal to the distance between adjoining paragraphs is secured at the front or rear of the character string. Further, in the case of this embodiment, dot patterns representing the lateral ruled lines are not provided. Namely, the lateral ruled lines are printed by changing values, which are stored at predetermined locations in the print buffer and represents off-dots, into values, each of which represents an on-dot, through software, or by forcibly changing off-dots at predetermined locations in the print buffer into on-dots when the contents thereof are transferred to the thermal printing head 32. The positions of the lateral ruled lines are automatically determined according to the width of tape loaded in the device and the combination of the character sizes employed for each line (incidentally, information representing the positions of the lateral ruled lines is stored in the ROM 22 as table information). Next, the CPU 21 judges in step 629 whether a border, a tabular frame or a rounded tabular frame should be added to the next paragraph. If should be added thereto, the CPU 21 judges in step 630 whether the kind of a frame to be added to the next paragraph is the same as that of the frame added to the current paragraph. If the frames respectively added to these paragraph are of the same kind, the CPU 21 instructs in step 631 to print a connecting ruled line (whose dot pattern is preliminarily provided in the device) as the rear ruled line of the frame added to the current paragraph. If neither a border, nor a tabular frame, nor a rounded tabular frame is added to the next paragraph or the kind of a frame to be added to the next paragraph is different from that of the frame added to the current paragraph, the CPU 21 instructs in step 632 to print a designated rear ruled line. Thereafter, in step 623, the CPU 21 checks whether or not the printing of the last paragraph has been finished. Subsequently, in step 624, the CPU 21 increments the parameter n by 1. Then, the CPU 21 is returned to step 621. Incidentally, as illustrated in FIG. 7, a space portion having a width equal to the distance between adjoining paragraphs is secured at the rear of the printed rear ruled line. In the case of this embodiment, the bold frame of FIG. 4(A1) and the tabular frame of FIG. 4(B) are regarded as of the same kind. Similarly, the bold rounded frame of FIG. 4(A2) and the rounded tabular frame of FIG. 4(C) are regarded as of the same kind. Incidentally, FIG. 6 illustrates the printing operation of printing ruled lines for the purpose of making characteristic features of this embodiment clearly understandable. Thus, in this figure, the relation between the loading of dot patterns into the print buffer and the transferring of the contents of the print buffer to the thermal print head 32 is explicitly illustrated. Thus, after all of necessary dot patterns are loaded into the print buffer, the dot patterns may be transferred to the thermal print head 32. The loading of the dot patterns into the print buffer and the transferring of the dot patterns to the thermal print head 32 may be performed concurrently with each other. Here, it is assumed that an (m-1)th paragraph is accompanied with neither a border, nor a tabular frame nor a rounded tabular frame, that an mth paragraph is accompanied with a bold frame and contains a character string "FIRST GROUP" as illustrated in FIG. 8(A), and that an (m + 1)th paragraph is accompanied with a tabular frame and contains three lines of character strings "SUZUKI××", "TAKAHASHI○○○" and "SATOHΔΔ" as illustrated in FIG. 9(B). In such a case, a table of FIG. 8(C) can be obtained by executing the processing program of FIG. 6. As described above, the character information processor of the aforementioned (first) embodiment has a tabular frame and a rounded tabular frame in addition to a border as enclosing patterns for enclosing a character string of a paragraph. In the case that a tabular frame or a rounded tabular frame is designated, if the paragraph consists of characters of lines of different lengths, the distance between the front and rear ruled lines is determined on the basis of the longest line of characters. It is, therefore, unnecessary to equalize the lengths of the lines of characters contained in the paragraph. Moreover, enclosing patterns for a tabular frame and a rounded tabular frame are provided in the processor of this embodiment. Furthermore, the characters of each line are printed according to the designated one of the enclosing patterns. The character information processor of this embodiment, however, does not need to perform an operation of enclosing a character string on each line in a paragraph, differently from the conventional character information processor. Further, when the frames (namely, the enclosing patterns) respectively added to paragraphs adjoining in the longitudinal direction of tape are of the same kind, the character information processor of the aforementioned (first) embodiment operates in such a manner as to connect these enclosing patterns with each other. Thereby, an operation of making a table can be simplified. Moreover, the operability of the processor can be enhanced. Although the front and rear ruled lines of the enclosing pattern used to make a table are printed lines in the case of the first embodiment, each of the front and rear ruled lines 'may be replaced with pictorial symbols aligned in a column (or row). Moreover, the connecting ruled line is not limited to the line as illustrated in FIG. 7 but may be replaced with pictorial symbols aligned in a column (or row), similarly. In the case that the front ruled line, the rear ruled line or the connecting line is linear, such a line may be formed by changing predetermined dots contained in the print buffer into on-dots by means of software, instead of using a dot pattern read from the CG-ROM 24. As above described, the tape printing device of this embodiment has the function of restoring a character string on inputting and editing characters, as a character editing function. Moreover, the tape printing device of this embodiment further has the function of editing spaces for intentionally blank portions when printing, and the function of generating ruled lines. The addition of these functions to the device, however, causes the inconvenience of setting the device to a user who is unskilled in operating the device, or to a user who wishes to make the device perform only a simple printing operation. Thus, the tape printing device of this embodiment is adapted to show a user a group of predetermined options or choices and to cause a phased-change in the number of alternatives to be selected, according to a command inputted by the user. Here, the term "an alternative level" is defined as a stage of the number of alternatives to be shown to a user. In the case of this embodiment, there are two "alternative levels", namely, "Level 1" and "Level 2". In the case of "Level 1", the number of alternatives is small. In contrast, in the case of "Level 2", the number of alternatives is large. Thus, kind-of-option information representing an alternative level designated correspondingly to each alternative, at which level a corresponding alternative is shown to a user as a candidate for the selection, is added to information representing the corresponding alternative, which is provided in the ROM 22. Incidentally, information representing an alternative level designated by a user is stored in the RAM 23. In the case of the tape printing device of this embodiment, the concept of the alternative level is introduced into items to be set (or options) respectively corresponding to the printing effects such as character modes, paragraph styles and text formats. Moreover, the concept of the alternative level is introduced into items to be set respectively corresponding to functions such as a file edition function, a bar-code-standard designating function and a consecutive number adding function. Next, alternative levels corresponding to an item or option (in this case, a set of all of text formats is employed as an example of the item) will be more practically described hereinbelow. FIGS. 10(A) to 10(E) illustrate a menu hierarchical structure of text formats, which is stored in the ROM 22 as a table. Incidentally, although the menu of text formats has a three-layer structure, FIGS. 10(A) to 10(E) illustrate only first and second layers thereof. Further, a third hierarchical layer is used to fetch data concerning the length of tape and is unrelated to alternative levels (incidentally, the third hierarchical layer corresponds to "Level 2", from a different point of view). In the case that a set of all text formats is employed as an item to be set, menu items of a first hierarchical layer of FIG. 10(A), such as the "TEXT ALIGNMENT", "SPACE", "MIRROR IMAGE CHARACTER" and "RESTORATION" are alternatives, to which symbols representing kinds of alternatives "1", "1", "2" and "1" are respectively added. Further, the alternatives, to which the kind "1" is added, are those which can be shown to a user as a candidate for the selection when the alternative level designated by the user are " Level 1" or "Level 2". Moreover, the alternative, to which the kind "2" is added, is an alternative which can be shown to a user as a candidate for the selection only when the alternative level designated by the user is " Level 2". The alternative "ALIGNMENT" relates to the length of a label and the position of a text in the label. Further, the alternative "SPACE" relates to the length of each of front and rear spaces provided at the front and rear of a label, respectively. Moreover, the alternative "RESTORE" is to reset all of the values of formats to default values thereof. Namely, the kind "1" is added to the alternatives, the necessity of which is relatively high. On the other hand, the alternative "MIRROR IMAGE CHARACTER" is to instruct the device to print a character by using a mirror image character or a normal image character. It is considered rare to instruct the device to print the character by using a mirror image character. Namely, the kind "2" is added to such an alternative, the necessity of which is relatively low. Incidentally, this embodiment employs the CPU 21 which processes data in units of 8 or 16 bits. Thus, each of the kinds of alternatives is represented by using 8 bits as illustrated in FIG. 10(E). Further, the least significant bit (LSB) represents whether an alternative corresponds to "Level 1" (namely, the LSB has a logical value "1") or the alternative does not correspond to "Level 1" (namely, the LSB has a logical value "0"). Moreover, the second least significant bit represents whether an alternative corresponds to "Level 2" (namely, the second least significant bit has a logical value "1") or the alternative does not correspond to "Level 2" (namely, the second least significant bit has a logical value "0"). The other six high-order bits are unrelated to the alternative levels. Therefore, data, whose two low-order bits are "11", is given to the alternative of the kind "1" as the kind-of-alternative information. Similarly, data, whose two low-order bits are "10", is given to the alternative of the kind "2" as the kind-of-alternative information. When making a choice, if the alternative level designated by a user is "Level 1", an alternative to which the kind-of-alternative information, whose LSB is "1", is given, is retrieved. Further, if the alternative level designated by a user is "Level 2", an alternative to which the kind-of-alternative information, whose second least significant bit is "1", is given, is retrieved. In the cases of the alternatives "TEXT ALIGNMENT" and "SPACE", which are of the kind "1" and correspond to alternatives of the second hierarchical layer (and are the items to be set), symbols representing the kinds of alternatives of the second hierarchical layer are established correspondingly to the necessity thereof, as illustrated in FIGS. 10(B) and 10(C). In contrast, in the case of the alternative "MIRROR IMAGE CHARACTER", which is of the kind "2" and corresponds to alternatives of the second hierarchical layer, the kind "2" is similarly set as the kind of the corresponding alternatives of the second hierarchical layer, as illustrated in FIG. 10(D). This is natural because the alternative "MIRROR IMAGE CHARACTER" of the kind "2" is not selected from the alternatives of the first hierarchical layer. In the foregoing description, an example of setting the symbols representing the kinds, which correspond to the alternative levels, in the case that the item to be set (namely, the option) is a set of all of text formats (namely, the styles of text formats) has been described. However, as to the other items of the first and second hierarchical layers, symbols representing the kinds, which correspond to alternative levels, are preliminarily set in a similar manner. Operation at Power-on: Next, an operation at power-on will be described in detail hereunder by referring to FIG. 11(A). In the case of this embodiment, a designated alternative level can be changed by turning on the power by depressing a power key when an alternative level alteration key is pushed at power-off. When the power is turned on and moreover, stable power comes to be supplied to the CPU 21, the CPU 21 starts executing a processing program of FIG. 11(A). Namely, the CPU 21 judges in step 700 whether or not the alternative level alteration key is depressed. If not depressed, the CPU 21 advances to step 710 whereupon a normal starting-up operation at power-on is performed. For example, the name of the device, a currently employed method for inputting characters (such as a Roman-letter inputting method and a hiragana-character inputting method) and a currently designated alternative level are displayed on the screen of the LCD for a predetermined period of time. Thereafter, the character input screen is displayed thereon. If the alternative level alteration key is depressed, the CPU 21 judges in step 701 whether there is a character string (or a text) still in the text area of the RAM 23 which has been backed up even at power-off. If still present therein, the CPU 21 advances to step 710 whereupon the normal starting-up operation at power-on is performed. In the case of this embodiment, it is not clear whether a user wishes to apply the alternative level designated before changed or an alternative level designated after changed to the character string (or the text) left in the text area. Moreover, in the case of allowing the device to apply the alternative level, which is designated after changed, to the character string (or the text) left in the text area, it sometimes becomes necessary to perform a regulation concerning the alternatives having been already selected. Thus, the alteration of the option level is permitted only when no character string (or text) is present in the text area. Therefore, in the case that a user wishes to change the alternative level, a user should perform the following process. Namely, all of character strings are first deleted or erased. Then, the power is turned off tentatively. Thereafter, the user should perform a power-on operation which includes an operation of depressing the alternative level alteration key. In contrast, if no character strings are present in the text area, the CPU 21 causes the LCD 35 in step 702 to display a message prompting a user to enter a password. Then, in step 703, the CPU 21 fetches a password inputted from the key entry portion 11. Subsequently, in step 704, the CPU 21 compares the inputted password with a password stored in, for example, the ROM 22 so as to judge whether the inputted password is correct. If not correct, the CPU 21 powers down the device in step 705. Namely, the device is returned to a situation in which the operation of changing the designated alternative level is started all over again. Although the normal starting-up operation may be commenced by maintaining the existing alternative level even if the inputted password is not correct, the user, however, has once started the operation of changing the designated alternative level. Thus the device is adapted to power-down so that the user can perform the operation of changing the designated alternative level again. In contrast, if the inputted password is correct, the CPU 21 changes the currently designated alternative level into another new alternative level in step 706. Then, the CPU 21 causes a preservation buffer (to be described later) to store the new alternative level. Subsequently, the CPU 21 causes the LCD 353 in step 707 to display a message, which indicates that the operation of changing the designated alternative level is finished, for a predetermined period of time. Thereafter, the CPU 21 advances to step 710 whereupon the normal starting-up operation at power-on is performed. Each time when the process described hereinabove is performed, the designated alternative level varies between "Level 1" and "Level 2". Here, the reason why the alteration key and a power key are depressed almost at the same time for the purpose of changing the designated alternative level is as follows. Namely, the designated alternative level should be prevented from being changed wrongly or carelessly. Consequently, a user can be prevented from being confused with various operations owing to the wrong change of the designated alternative level. Thus, the device is adapted to accept an instruction to change the designated alternative level only when a user clearly intends to instruct the device to do so. Incidentally, the designated alternative level is factory-configured to "Level 1", the number of alternatives corresponding to which is relatively small. The designated alternative level is stored in the (designated-alternative-level) preservation buffer provided in the RAM 23 and a text attribute storage region contained in the text area which is provided in the RAM 23. The designated alternative level stored in the preservation buffer is applied in common to each of newly inputted texts. On the other hand, the designated alternative level stored in the text attribute storage region corresponds to a text corresponding to the text attribute storage region. Generally, the designated alternative stored in the preservation buffer is the same as that stored in the text attribute storage region. However, these alternative levels may be different from each other in the case that a file is preserved in an external storage device and thereafter, the file is read therefrom. In such a case, higher one of these alternative levels takes first preference. Operation of Selecting One of Alternative on Item to Be Selected: Next, an operation of selecting one of alternatives according to an alternative level newly designated by performing the operation of changing the designated alternative level will be described hereinbelow by referring to a flowchart of FIG. 11(B). Incidentally, FIG. 11(B) illustrates such a selecting operation in the case of using a two-layer menu. When starting the execution of a processing program of FIG. 11(B) by operating an attribute designating key or the like, the CPU 21 causes the LCD 35 in step 720 to display a preferential alternative (for example, a currently established alternative) of the first hierarchical layer corresponding to the currently designated alternative level thereon as a candidate. Thereafter, the CPU 21 judges in step 721 which of the selection key and the candidate alteration key is operated. If the candidate alteration key is operated, the CPU 21 causes the LCD 35 in step 722 to display another alternative of the first hierarchical layer corresponding to the currently designated alternative level thereon as a candidate. Then, the CPU 21 is returned to step 721. On the other hand, if an alternative of the first hierarchical layer is definitely determined by operating the selection key, the CPU 21 judges in step 723 whether the alternative of the first hierarchical layer needs the selection of an alternative of the second hierarchical layer. If there are corresponding alternatives of the second hierarchical layer and one of the corresponding alternatives should be selected, the CPU causes the LCD 35 in step 724 to display a preferential one (for instance, a currently set one) of the corresponding alternatives of the second hierarchical layer on the screen thereof as a candidate. Thereafter, the CPU 21 judges in step 725 which of the selection key and the candidate alteration key is operated. If the candidate alteration key is operated, the CPU 21 causes the LCD 35 in step 726 to display another corresponding alternative of the second hierarchical layer, which further corresponds to the currently designated alternative level, on the screen thereof. Then, the CPU 21 is returned to the key judgement step 724. If the established alternative of the first hierarchical layer does not need the selection of one of the corresponding alternatives of the second hierarchical layer, or if such selection of one of the corresponding alternatives of the second hierarchical layer is finished, the CPU 21 causes the text area in step 727 to store information concerning the selected alternative, which is stored in a working area for the processing program, therein by being accompanied by a text stored therein. Thus the CPU 21 finishes a sequence of the steps of this operation. In the cases of employing a single-layer menu and a three-layer menu, operations similar to that of FIG. 11(B) are performed. Thereby, alternatives of each of the hierarchical layers corresponding to the designated alternative level are set. In the case of the aforementioned (first) embodiment, an alternative level is assigned to each of the alternatives. Further, only alternatives, to which the alternative level designated by a user, are employed as candidates for the selection. Thereby, a character information processor, which has good operability and can easily fulfill both of a user request for the operability and a request for the degree of freedom of the contents of a produced label, can be realized. For example, when a user makes a label of a simple structure, operations of designating various kinds of attributes can be easily achieved by designating "Level 1". In contrast, when a user makes a label of an elaborate structure, such a label can be freely made by designating "Level 2" without being under restrictions due to the selection of attributes. Although the modifications of the first embodiment (namely, the embodiments other than the first embodiment) have been described in the foregoing description, other embodiments will be further cited as follows. The first embodiment has two alternative levels. Another embodiment may have three or more alternative levels. In such a case, a password may be established corresponding to each of the alternative levels. Further, in the case of the first embodiment, the designated alternative level can be changed only just after turning on the power. However, in the case of still another embodiment, the designated alternative level may be changed at a time other than the time when the power is turned on. Moreover, in the case of the first embodiment, the alteration of the designated alternative level is permitted in a state in which all of character strings are erased. However, in the case of yet another embodiment, the alteration of the designated alternative level may be permitted in a state in which a character string is still left in the text area. In this case, it is preferable that various alternatives on existing character strings are automatically changed according to a newly designated alternative level by providing an alteration table between a group of alternatives corresponding to "Level 1" and another group of alternatives corresponding to "Level 2". For instance, when the designated alternative level is changed from "Level 2" to "Level 1", the selection of the alternative "MIRROR IMAGE CHARACTER" may be canceled. Furthermore, in the case of the first embodiment, alternatives permitted correspondingly to each of the alternative levels are invariably held by the device. However, in the case of a further embodiment, the correspondence relation between each alternative level and a group of alternatives permitted correspondingly thereto may be freely set or modified by a user. Namely, the contents of the column "KIND" of FIGS. 10(A) to 10(D) may be rewritten by a user. For example, the contents of the column "KIND" of FIGS. 10 (A) to 10(D) may be rewritten by providing a processing program of modifying individual alternative level in the device, and by then displaying all alternatives and kind-of-alternative information corresponding to the alternatives in order, and by next modifying the kind-of-alternative information and by subsequently rewriting the contents of the kind-of-alternative information of FIGS. 10(A) to 10(D) according to the modified values or contents of the kind-of-alternative information. Additionally, in the case of the first embodiment, the procedure, by which the designated alternative level is changed from "Level 1" to "Level 2", is similar to the procedure, by which the designated alternative level is changed from "Level 2" to "Level 1". However, in the case of another embodiment, these procedures may be different from each other. For instance, the alteration of the designated alternative level from "Level 2" to "Level 1", by which the number of alternatives is reduced, may be performed by a simple step such as the depression of a return key or the like. In addition, the items, the number of the selectable alternatives corresponding to each of which can be changed according to the designated alternative level, are not limited to those employed in the first embodiment. For example, the kind of symbols, which should be displayed when entering symbols, may be made to correspond to the alternative levels. Incidentally, in the case of the first embodiment, the present invention is applied to the tape printing device. The present invention, however, is applied to other character information processors, each of which employs many options on the attributes for exerting the printing effects. For example, the present invention can be applied to a seal making device.
