Description

  The present invention relates to an input / output device applicable to an output device such as a label printer. Specifically, only output information in a format that matches the output device for print output can be selected and output.

  In order to display the inspection results of the products flowing through the factory production line in the product bag, and to display the names of agricultural products and raw materials such as processed foods on the stuffing bag, a sticker label displaying the contents is used Often done.

  A well-known label printer is used for label printing (for example, Patent Document 1). As shown in Patent Document 1, when the label printer itself is provided with such an input operation unit, input and correction of the display content can be performed using this input operation unit. On the other hand, if a dedicated input / output device giving priority to usability is prepared, the input work efficiency will be improved compared to using the input operation unit itself of the printer body. There will be more opportunities to use.

  When such a dedicated input / output device is used, a personal computer or the like, which is an information processing means usually installed in an office, is used to input display contents necessary for label printing, Settings such as layout are executed. The created label printing information is stored in an external storage means such as a compact memory (memory card), and a dedicated input / output device installed in a department that conducts an inspection line of a factory that is a work site or an agricultural work warehouse. The final correction work is performed using.

  Since the information itself stored in the external storage means is label printing information that can be shared, if it is a factory inspection line, the created label printing information can be displayed using a dedicated input / output device near the inspection line. You can easily add or modify the inspection line designation, inspector name, etc. to the base. Immediately after the correction processing, the label printing information after correction can be printed using a label printer.

  Similarly, in the case of agricultural products and various processed foods produced in factories, the food label is printed with the item, raw material name, content, expiration date / expiration date, manufacturer name, etc. Read the label printing information from the external storage means using a dedicated input / output device installed at the packing work site, etc., and if correction is necessary, set the items packed in the bag, correct the content, etc. In addition, the food label can be generated by supplying the label printing information to the label printer.

  As described above, an apparatus in which auxiliary input means for a printer as a printing apparatus is configured separately from the printer is already known (for example, Patent Document 2 and Patent Document 3). The technique disclosed in Patent Document 2 is configured such that a keyboard, a liquid crystal display device, and a printer are configured separately. The technique disclosed in Patent Document 3 is provided with a cursor pad separately from the keyboard.

JP 2003-111941 A JP-A-6-274244 JP-A-7-25074

  In the technology disclosed in Patent Document 2 described above, the liquid crystal display device has the same function as a display unit of a personal computer as an information processing device, and input information is added to the liquid crystal display device. , There is no editing function to perform correction work to delete. Therefore, it is not possible to perform correction processing of information to be printed by placing a liquid crystal display device near the printer.

  In the technique disclosed in Patent Document 3, since the cursor pad only has a control key for controlling the printer unit of the typewriter, the cursor pad is input separately from the typewriter. It does not function as a means. For this reason, even if this cursor pad is installed near the typewriter, information cannot be corrected using this cursor pad.

  By the way, the dedicated input / output device described above is often configured as a stand-alone device to which a plurality of label printers can be connected. The plurality of label printers may be new and old model (new and old version) label printers, or label printers having different printable label sizes and resolutions. In general, these label printers are often configured to receive data from a dedicated input / output device and print the received data even if the model or version is different.

  On the other hand, in the case of a dedicated input / output device configured to output label printing information to a plurality of label printers, the label printing information is also label printing information corresponding to the plurality of label printers. The label print information is stored in an external storage means such as a compact memory.

  The user accesses the external storage means and selects a file that matches the model and version of the label printer to be connected, for example, a folder in which corresponding label printing information is stored. Then, from the files (label printing information) stored in the folder, select the file that matches the corresponding item, and then perform correction processing, or output to the label printer as it is without correction processing. Will move on.

  This is because depending on the label printer, the usable label size is different and the printing resolution is different, so it is necessary to select a file suitable for the connected label printer.

  Therefore, since it is configured to be compatible with a plurality of label printers, conventionally, it is necessary to select folder and file information related to the connected label printer. However, even when file information suitable for the label printer is not selected, the selected file information can be output to the label printer and printed as described above.

  As a result, it is impossible to eliminate the possibility that label information is printed on labels having different label sizes, or that label information is printed with an inappropriate resolution. If you monitor the printing status of the label output from the label printer, you can check whether it is printed based on the appropriate label printing information, but bagging work is always a struggle with time. In many cases, there is no room to confirm the first printed content calmly. As a result, incompatible label printing processing may occur.

  This is because such a printing process error does not take into consideration the consistency between the model information and version information of the label printer connected to the dedicated input / output device and the selected file information.

  Therefore, the present invention solves such a conventional problem, and proposes an input / output device that can select only output information that matches an output device such as a connected label printer. .

  In order to solve the above-mentioned problem, an input / output device according to the present invention described in claim 1 has means for acquiring attribute information of an output device and attribute information adapted to the attribute information by accessing an external storage means It is characterized by comprising means for obtaining a file, means for displaying the obtained file on a display unit, and means for outputting output information stored in a designated file to an output device. According to the seventh aspect of the present invention, there is provided an input / output processing method according to the present invention, comprising: obtaining attribute information of an output device; and a file having attribute information adapted to the attribute information by accessing storage means storing the file A step of displaying the acquired file on the display unit, and a step of outputting the output information stored in the designated file to the output device.

  The present invention displays in advance information to be output to an output device, for example, information to be printed on a label printer (label printing information) when the output device is a label printer, and creates it in advance if necessary. The present invention relates to an input / output device used when the label printing information is corrected and information is printed on the label based on the corrected label printing information.

  Accordingly, in many cases, label print information is created in advance by a personal computer or the like as an information processing apparatus. Of course, it is also possible to use a label printing information created by the input / output device itself.

  Label printing information created by a personal computer or the like is stored in an external storage means. The label printing information is created for each label printer to be used according to the specifications of the label printer.

  Depending on the label printer, the printable label size, resolution, etc. may be different. For this reason, the label print information is stored together with the attribute information of the label printer. As attribute information of the label printer, attribute information (printer ID) for identifying the label printer can be considered.

  The number of label printers used by the user is not limited to one, and there may be old and new versions of the same model, or the model may be different even with a single label printer. For this reason, the label print information stored in the external storage means often includes label print information corresponding to various types of label printers.

  When printing the information on the label using the label printing information stored in the external storage means, whether to print the label after correcting the label printing information or whether to print directly without modification It is left to the user.

  When printing on the label, the input / output device is connected to the label printer. At this time, attribute information is acquired from the label printer. The acquired attribute information and the label printing information file stored in the external storage means are referred to.

  A file having printer information matched with the acquired printer ID is selected. In other words, the stored file is referred to, collated with the attribute information stored together with the label printing information, and only the file having the matching attribute information can be selected. The file name of the selected file is displayed on the display unit. Specific file information is selected from the displayed file name.

  By this selection process, the label print information stored in the selected file is displayed, so that the label print information correction process is performed when necessary. For example, the label print information is updated by correcting the item to be shipped (agricultural product) or by correcting the number to be shipped (number of labels printed).

  The updated label printing information is stored in the external storage means and is output to the label printer side. On the label printer side, a printing process for a specified number of labels is executed based on the received label printing information.

  Since only a file that matches the attribute information of the label printer connected in this way can be used, there is no mistake of reading a file with different attribute information and outputting the label print information.

  When the label printer is not connected to the input / output device, the file used immediately before is selected. Then, a warning process to the effect that the label printer is not connected is performed to prompt connection of the label printer. The label printer connected to the input / output device is considered to be a label printer having the same attribute information as the attribute information of the file used immediately before. In this case, it is determined that the selected file is compatible with the label printer. Then, after performing correction processing as necessary, the updated label printing information is supplied to the label printer.

  Therefore, even in this case, only files that match the attribute information of the label printer can be used, so there is no mistake of reading a file with different attribute information and outputting the label print information.

  In the present invention, since only output information such as print information that matches an output device such as a connected printer can be selected, the print information can be always printed with the same specifications as the connected printer. Have Since the selection of print information that matches the connected printer is automatically performed, print processing without error can be realized.

It is a systematic diagram showing an example of a print processing system showing an example of use of a printing input / output device according to the present invention. FIG. 4 is a key layout diagram illustrating an example of an input operation unit of a printing input / output device. It is a block diagram which shows an example of the processing system of the input / output device for printing. It is a flowchart which shows the example of a file selection process of the input / output device for printing. It is a flowchart which shows the modification of the file selection process of the input / output device for printing. It is a flowchart which shows the other modification of the file selection process of the input / output device for printing. It is a systematic diagram which shows the modification of the printing processing system of this invention.

  Next, a preferred embodiment of a printing input / output device as an example of an input / output device according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a system diagram of an essential part showing an example of a printing processing system 10 to which a printing input / output device 40 according to the present invention is applied. In this printing processing system 10, a processing system is described in which label printing information, which is output information, is created in advance and the information is printed on a label.

  The print processing system 10 includes an information processing device 20 for creating label print information, a print input / output device 40 according to the present invention, and a label printer 30 as an example of an output device.

  A personal computer is a typical example of the information processing apparatus 20, and various information necessary for label printing is input by operating a keyboard (not shown) which is an input means of the personal computer. At this time, label printing information is created according to which label printer is used for printing and the specifications of the label printer to be used.

  The attribute information of the label printer itself that can identify the label printer to be used is stored in association with the label printing information. Therefore, when the model and model of the label printer to be used are different, they are classified and stored for each model and model. Normally, a folder is created for each model and model, and label printing information belonging to the same category is stored in the folder. Each file is managed with a different file name.

  As the file name, the name of the inspection line or the like is used if a factory-related label is printed, the product name (agricultural product name) or the like is used for agricultural products, and the processed food name or the like is used for processed foods Is done. The attribute information is automatically added in association with the label printing information, and a printer ID or the like can be used.

  The label print information created by the information processing apparatus 20 is stored in a removable external storage means 70. As the external storage means 70, a memory card, a USB memory or the like can be considered.

  The printing input / output device 40 is an input / output device having a correction function that allows only the label printing information that matches the connected printer as described above to be selected, and includes an input operation unit with a display unit. In addition, it has a mounting portion for external storage means.

  FIG. 2 shows an example of the input operation unit 42 in the printing input / output device 40, and a display unit 44 is provided at the upper front of the apparatus main body 43. The display unit 44 is composed of a liquid crystal display element or the like, and can display information in n rows and m columns at the same time. In this example, n = 10 and m = 5, but the values are arbitrary.

  A power key 46 and a shift key 48 are arranged on the lower side of the display unit 44. Further below the display unit 44, a numeric keypad (10 key) 50, an alphabet key 52, a function key 54, and the like are arranged in this example, and in this example, a correction item confirmation (update) key 56 and a label printer are arranged. The output key 57 is arranged. Further, a mounting portion 58 of the external storage means 70 is provided on the left side surface of the apparatus main body 43. In this example, since the memory card type external storage means 70 is illustrated, the mounting portion 58 has a slot configuration in which a memory card can be mounted.

  When the power is turned on and the external storage means 70 is attached to the attachment portion 58, a predetermined file is read from the attached external storage means 70. When reading the file, the attribute information of the label printer 30 connected to the printing input / output device 40 is referred to.

  Therefore, when the label printer 30 is connected to the printing input / output device 40, the attribute information of the label printer 30 is automatically read as soon as the power is turned on. The attribute information of the label printer 30 such as the printer ID is stored in a memory means (described later) built in the apparatus main body 43. It may be discarded when the attribute information matching process is completed without saving.

  When reading from the external storage unit 70 is executed, the attribute information is referred to, checked with the attribute information of the file stored in the external storage unit 70, and processed as a file that can be read only by the file having the matched attribute information. Is done. That is, only the file having the same attribute information as the label printer connected to the printing input / output device 40 can be read and displayed on the display unit 44. Then, the label print information is specified by selecting a specific file.

  The specific label print information can be corrected (edited) such as addition or deletion using the key group of the input operation unit 42, and the corrected information is stored in the external storage unit 70 again. By operating the output key 57, the selected or updated label printing information can be output to the label printer 30 side.

  In order to read out a file related to attribute information different from the attribute information of the label printer 30, the above-described file reading process may be canceled once.

  The printing input / output device 40 is an input / output device having a correction function so that only label printing information that matches the printer connected as described above can be selected.

  Therefore, the printing input / output device 40 has means for acquiring a file having attribute information suitable for the attribute information by accessing the external storage means in addition to the means for acquiring the attribute information of the label printer, And a means for outputting label print information stored in the designated file to the label printer.

  In addition to this, when the attribute information cannot be acquired, the embodiment has means for acquiring the most recently accessed file with reference to the access history in the external storage means. Furthermore, it has warning processing means for performing warning processing when attribute information cannot be acquired.

  FIG. 3 is a block diagram showing an outline of the processing system of the printing input / output device 40. In FIG. 3, a central processing unit (MPU) 62 that controls the entire apparatus is provided, and a memory means (ROM) 64 storing a processing program and the like and a working memory means (RAM) 66 are a common bus. 68 to be connected to each other. The memory means 64 acquires attribute information of the label printer 30 connected to the apparatus main body 43 as will be described later, or collates with attribute information acquired from a file stored in the external storage means 70 to match. A file selection processing program for executing processing for selectively displaying only the attribute information file to be stored is stored.

  Further, the above-described input operation unit 42 and display unit 44 are connected to the common bus 68, and the external storage means 70 and the communication interface unit 74 for communicating with the outside are connected to each other. The Communication with the label printer 30 can be performed by the communication interface unit 74, and a printer ID which is attribute information of the label printer 30 can be acquired.

  In the label printer 30, a label printing process is executed based on the label printing information input via the connection cable 72 or the label printing information stored in the built-in memory (not shown) of the label printer 30 itself. .

  In the label printer 30, a printing process is executed for the designated number of labels (not shown) of the label size designated on the printing input / output device 40 side. For example, when used on a factory inspection line, the factory name, inspection line, person in charge of inspection, inspection date, etc. are printed on the label.

  When an agricultural product is shipped, the product name, production area, producer name, shipping date, etc. of the agricultural product are printed on a label and output. In the case of processed food products, the label printing information includes food name, raw material name, expiration date (expiration date), content, manufacturer name (seller name), etc. Printed on the label and output.

  As a label printer 30 as a printing apparatus, as shown in Patent Document 1, the printer main body has an input operation unit having a display unit, and the printer main body can also set the number of prints and easily correct label print information. The label printer with the input operation unit, the label printer without the input operation unit, or any type of printer can be used. When the printing input / output device 40 is actively used, there is a strong tendency to use a relatively inexpensive label printer that omits the latter type of input operation unit.

  The print head system of the label printer 30 may be a thermal transfer type or a thermal type.

  In the printing processing system 10 shown in FIG. 1, the printing input / output device 40 is used while being connected to the label printer 30. Then, the external storage means 70 is attached to the attachment portion 58.

  FIG. 4 is a flowchart showing an example of the file selection process in the present invention. The file selection processing program is activated by turning on the power of the printing input / output device 40. When the file selection processing program is activated, the connection status of the label printer 30 is first monitored (step 80).

  When the label printer 30 is connected, communication is performed with the label printer 30, and attribute information (for example, printer ID) is acquired from the label printer 30 (step 81).

  Next, the external storage unit 70 is accessed, referring to the acquired attribute information and the label print information file attribute information stored in the external storage unit 70 (printer ID or information related to the printer ID). The attribute information is collated (step 82).

  This attribute information collation process may be a collation process in which the file information in the external storage means 70 is read in advance into the memory means of the apparatus main body 43, for example, the RAM 66, and the attribute information stored in the read file. Good.

  When it is confirmed that the printer information matched with the acquired printer ID exists, the file is selected and read (step 82). That is, the stored file is referred to and compared with the attribute information stored in association with the label print information, and only the file having the matched attribute information can be selected.

  The file name of the selected file is displayed on the display unit 44. The file to be printed is selected from the displayed file name. As the file name, an inspection line name, an agricultural product item, a processed item, or the like can be considered.

  By this selection process, the label print information stored in the selected file is displayed. Therefore, the label print information correction process (edit process) is performed when necessary (step 83). For example, the label print information is updated by correcting the item to be shipped (agricultural product) or the number of items to be shipped (number of label prints), and then the update information is confirmed by the confirm key 56 (step 83). .

  The updated label printing information is stored in the external storage means 70, and the operation of the output key 57 shown in FIG. 2 is monitored to confirm the output instruction to the label printer 30 (step 84). If there is an output instruction, it is next checked whether the printer ID, which is the attribute information of the label printer 30, has been acquired (step 85).

  If the attribute information of the label printer 30 has already been acquired, the updated label print information is output to the label printer 30 as it is (step 86). In this series of processing, the label printer 30 performs printing processing on the label for the designated number of sheets based on the received label printing information.

  On the other hand, if it is determined in step 80 that the label printer 30 is not connected to the apparatus main body 43, the external storage means 70 is accessed to read the previous history information (step 90). Thereafter, the most recently read file is read from the previous history information and displayed on the display unit 44 (step 91). Thereafter, the process proceeds to a correction process (editing process) in step 83, and the same process as described above is executed. When the output key 57 is operated, the printer ID acquisition state is determined (steps 84 and 85).

  When the process proceeds from step 90 onward, since the label printer 30 is not connected to the printing input / output device 40, it is determined in step 85 that the printer ID has not been acquired, and warning processing is performed. (Step 92). In the example of FIG. 4, as a warning process, a warning message is displayed on the display unit 44 to prompt a connection process. As a warning message, “Please connect a label printer” or a model that can be connected is known in advance (step 91), so a message such as “A label printer that can be connected is XXX” is displayed. Conceivable.

  As warning processing, in addition to the warning message display described above, warning processing such as sounding a buzzer can be considered. Warning message display and alarm processing can be used together.

  Subsequently, the connection with the label printer 30 that matches the warning message is confirmed (step 93). When the matched label printer 30 is connected, the printer ID is acquired from the label printer 30 and stored (step 94), and the label print information corrected in step 83 is output to the label printer 30 (step 94). 86). Therefore, in this series of processing, the label printer 30 performs printing processing on the label for the designated number of sheets based on the received label printing information.

  As described above, when the label printer 30 is not connected, the process immediately selects the file used immediately before with reference to the immediately preceding history information (access history information). Since the label printer 30 connected to the output device 40 is considered to be a label printer having the same attribute information as the attribute information of the file used immediately before, it is determined that the file used immediately before is compatible with the label printer. This is because it is considered safe.

  Since only files that match the attribute information of the label printer 30 connected in this way can be used, there is no mistake of reading a file with different attribute information and outputting the label print information. For example, it is possible to avoid a printing error such that the label size and the print size of the label print information do not match, and a part of the label print information is printed missing or printed in a larger size. In addition, it is possible to avoid a printing error such that the resolution does not match and clear printing cannot be performed.

  5 and 6 are flowcharts showing a modification of the file selection process in the present invention. In the modification shown in FIGS. 5 and 6, in the operation example described with reference to FIG. 4, as step 95, the file information of the file used immediately before being selected when the label printer 30 is not connected, and a new connection are added. A process for verifying the printer ID acquired from the label printer 30 is added.

  That is, the connection status of the label printer 30 is monitored in step 80. When the label printer 30 is connected, for example, a printer ID is acquired as attribute information of the label printer 30 in step 81, and the label printer 30 is acquired in step 82. Select and read the file that matches the attribute information.

  In step 83, label printing information is corrected or edited as necessary. When an output instruction is issued to the label printer 30 in step 84, a printer ID, which is attribute information of the label printer 30, is acquired in step 85. Check if it is done.

  If the label printer 30 is connected in step 80 described above, the attribute information of the label printer 30 has already been acquired. Therefore, the label print information updated in step 86 is output to the label printer 30 side. On the side, the label printing process is executed for the designated number of sheets based on the received label printing information.

  On the other hand, when it is determined in step 80 that the label printer 30 is not connected to the apparatus main body 43, the external storage means 70 is accessed in step 90 to read the previous history information, and in step 91, from the previous history information, The file read most recently is read and displayed on the display unit 44.

  In step 83, label printing information is corrected or edited as necessary. When an output instruction is issued to the label printer 30 in step 84, a printer ID, which is attribute information of the label printer 30, is acquired in step 85. Check if it is done.

  If the label printer 30 is not connected in step 80 described above, the attribute information of the label printer 30 has not been acquired, so a warning process is performed in step 92 and the process waits until the label printer 30 is connected. When the label printer 30 is connected in step 93, a printer ID which is attribute information of the newly connected label printer 30 is acquired in step 94.

  In step 95, the file information of the file used immediately before being selected when the label printer 30 is not connected is compared with the printer ID acquired from the newly connected label printer 30. If the preselected file information matches the attribute information of the newly connected label printer 30, the label printing information updated in step 86 is output to the label printer 30 and the label printer 30 receives the received label. Based on the printing information, a printing process on the label is executed for a specified number of sheets.

  On the other hand, if the preselected file information does not match the attribute information of the newly connected label printer 30, the process returns to step 82, and a file that matches the attribute information of the newly connected label printer 30 is obtained. After selecting and reading, the process proceeds to the correction or editing process in step 83, and the same process as described above is executed.

  In the file selection process shown in FIG. 6, when it is determined in step 95 that the preselected file information and the attribute information of the newly connected label printer 30 do not match, the preselected file information in step 96. Whether to save the corrected or edited label printing information is selected. If it is selected to save the label printing information, the file is saved with the contents corrected or updated in step 97 and the process returns to step 82. Then, a file that matches the attribute information of the newly connected label printer 30 is selected and read, and thereafter, the process proceeds to the correction or editing process in step 83, and the same process as described above is executed.

  If it is selected not to save the label printing information, the contents corrected or updated in step 97 are not saved and the process returns to step 82 to select a file that matches the attribute information of the newly connected label printer 30. After that, the process proceeds to the correction or editing process in step 83, and the same process as described above is executed.

  In the embodiment shown in FIGS. 5 and 6, even when a label printer 30 is newly connected, only a file that matches the attribute information of the label printer 30 can be used. Mistakes such as printing information output are eliminated. Further, in the embodiment of FIG. 6, the contents of editing can be saved even when printing cannot be performed using previously selected file information by not matching the attribute information of the newly connected label printer 30. Therefore, if the label printer 30 having matching attribute information is used, the printout can be performed without performing the editing operation again.

  The present invention is not limited to the label printer described above, and is a printing machine, a cutting machine, or the like that needs to select and output information that matches the type of output device to be connected, and performs some input or correction processing. Needless to say, the present invention can also be applied to a dedicated input / output device used in the system. The printing machine is an output device that prints out a sticker sheet with a print head based on print information such as characters and graphics. The cutting machine is a direction perpendicular to the feeding direction of the cutting sheet by cutting the cutting bite while feeding the cutting character sheet forward and backward along the sheet feeding path by the sheet feeding means based on the output information such as vector data. It is an output device that performs a reciprocating forward and reverse movement to the cut character sheet.

  In the present invention, the function of the input / output device may be provided in an information processing apparatus that creates label print information. FIG. 7 is a system diagram of a main part showing a modification of the print processing system 10. The print processing system 10 according to the modification includes an information processing device 20 and a label printer 30.

  The information processing apparatus 20 incorporates a program for executing the file selection process described with reference to FIG. 4, FIG. 5, or FIG. The program for executing the file selection process accesses the external storage means 70 or an internal storage means (not shown) by acquiring the attribute information of the output device such as the printer ID of the label printer 30, and the printer of the label printer 30. A step of acquiring file information having attribute information matched with the ID, a step of displaying the acquired file information on the display unit 44, and a step of outputting the selected file information to the label printer 30 are executed.

  A program for executing the file selection process is stored in a ROM (not shown) provided in the information processing apparatus 20, and is executed by the CPU. Further, it may be stored in an external storage means such as a disk storage medium, a USB memory, or a card storage medium.
