Description

  The present invention relates to a directory name determination method for storing print information.

  Conventionally, a printer performs printing based on print data sent from a host computer, but recently, a printing process can be executed without a host computer by attaching a memory card or the like storing image data. A model (for example, a stand-alone type) has become widespread. This type of printer is generally used to print images taken with a digital camera. Insert a memory card that contains images taken with a digital camera into the slot and specify the images and number of prints on the operation panel. Print processing is executed.

  Some stand-alone printers can be connected to an external storage device. The external storage device uses, for example, a portable recording medium such as an MO (Magnet-Optical disk) and is connected to the printer via a port provided in the printer. The image data stored in the memory card can be stored in the external storage device through the printer, and the storing operation (backup processing) is performed by operating the operation panel with the memory card inserted into the slot.

  As described above, the image data stored in the memory card can be stored by storing the image data in the external storage device. In general, image data is stored in an external storage device in a directory format conforming to DCF (Design Rule for Camera File system) widely used as a unified format for digital cameras.

  Patent Document 1 discloses the following technique so as not to overwrite an already stored image file when storing an image file of a memory card in an external storage device. In other words, the identification directory 51 is created immediately below the root directory 47 of the external storage device as shown in FIG. Then, a directory structure (DCIM directory 48, MISC directory 49, DCF directory 50) corresponding to the subdirectory of the memory card is generated under the identification directory 51, and image data is stored under the DCF directory 50. As a result, even if there is image data having the same file name as already stored image data, the image data is stored in a subdirectory under a different identification directory 51, and image data is lost due to overwriting of the image data. Can be prevented.

JP 2003-256159 A

  As described above, the identification directory 51 is created every time the storage process is performed, but its name starts with “001” and thereafter becomes “002” and “003” so that the serial number is 1 every time it is created. It is described in the paragraph “0051” of Patent Document 1 that the allocation is performed in increments.

  For this purpose, when the directory is created, the number of created identification directories 51 is counted, and the number obtained by adding 1 to the number is used as the name of the created identification directory 51, or the name of the created identification directory 51. It is conceivable that the name obtained by adding 1 to the largest number is the name of the identification directory 51 to be created.

  However, if the identification directory 51 already created in the external storage device is deleted, etc., and there is a vacancy in the serial number of the name, creation of the identification directory may fail or the utilization efficiency of the external storage device may deteriorate. Can happen.

  That is, in the method of naming the number obtained by adding 1 to the number of identification directories, for example, the identification directory 51 is “001”, “002”, “004”, “005”, and “003” is deleted. In this case, if the name of the identification directory 51 to be created is “005” obtained by adding 1 to 4 which is the number of identification directories, the creation of the identification directory 51 will fail because “005” already exists.

  Also, in the method of naming the largest number plus one, if the name of the identification directory 51 for creating “006”, which is the largest number “005” plus one, is created. It is possible, however, the vacancy remains in the serial number, and the utilization efficiency of the external storage device deteriorates. In particular, in this example, since the names of the identification directory 51 that can be created in the external storage device are finite from “001” to “999”, it is desirable to avoid deterioration of the utilization efficiency of the external storage device.

  An object of the present invention is to improve the success rate of group creation in determining the names of groups such as directories to be created on a recording medium and to avoid the deterioration of the utilization efficiency of the recording medium.

The group name determination method in the print information storage device according to one aspect of the present invention for solving the above-described problem is as follows.
A group in a printing information storage device that reads a first recording medium on which printing information is recorded and stores the printing information in groups each having a name by a symbol group that can be expressed as a serial number on the second recording medium A name determination method,
For the name of the group created when storing the print information, the continuity of the name of the group recorded on the second recording medium is determined. If there is no consecutive number, the symbol group following the serial number Is the name of the group, and when there is a vacancy in the serial number, any vacant symbol group is the name of the group.

  According to the present invention, when the continuity of the group name is determined and there is a vacancy in the serial number, the success rate of group creation is improved by making any vacant symbol group the name of the group, It is possible to avoid deterioration of the utilization efficiency of the recording medium.

Here, the determination of the continuity of the names of the groups recorded on the second recording medium is obtained by acquiring the number of groups recorded and the name of the symbol group next to the symbol group corresponding to the number of groups. You can judge by whether or not the group can be created,
If there is a vacancy in the serial number, it is determined whether it is possible to create a group with the name of the symbol group obtained by sequentially decrementing the serial number from the symbol group next to the symbol group corresponding to the number of groups. A group of symbols can be used as a group name.

Further, the present invention more specifically,
A directory name determination method in a printing apparatus that reads a first recording medium in which print information is recorded and stores the print information in a directory unit in which a name including a number is attached to a second recording medium,
As for the name of the directory created when storing the print information, it is determined whether there is no space in the directory name number recorded on the second recording medium. A directory name determination method in a printing apparatus is characterized in that a directory name including a number of +1 is used as a directory name, and if the number is empty, a directory name is included including any empty number. it can.

  Hereinafter, an embodiment of a printing apparatus and a printing information storage method embodying the present invention will be described with reference to FIGS.

  FIG. 1 is a perspective view of the printer 1. A printer 1 as a printing apparatus is an injection type printer having an operation panel 3 on the upper right side of a main body 2. A paper supply device 4 is provided on the back side of the main body 2, and a cut sheet set in the sheet feeder 5 or a roll paper set in the roll paper support unit 6 is fed into the main body 2. Below the cover 7 provided in the center of the main body 2, a printing mechanism to be described later is mounted, and a printing process is executed by the operation of the printing mechanism. Discharged.

  The operation panel 3 includes a display device 11 having a setting screen 10 and an operation unit 12 including a plurality of operation switches (operation buttons). The setting screen 10 is a monochrome liquid crystal. For example, a menu screen for manually selecting a paper type (cut sheet or roll paper), paper size (A4, etc.), layout, photo selection, number of prints, etc. is displayed in monochrome. Further, the operation unit 12 is provided with a power switch 13a for turning on the printer 1, a maintenance switch 13b that is pressed when an error occurs, and a roll paper switch 13c that is pressed when operating the roll paper. Yes.

  The printer 1 has a reading device 15 for inserting a memory card 14 for a digital camera, and prints an image read from the memory card 14 without being connected to a host computer (for example, PC) 16 (see FIG. 3). It is possible stand-alone. A memory card 14 is detachably attached to the slot 15a of the reading device 15. The memory card 14 includes, for example, a compact flash (registered trademark), a smart media (registered trademark), a memory stick (registered trademark), and the like. Each memory card 14 is attached to a dedicated adapter (not shown) and inserted into the slot 15a.

  A display device (monitor) 17 for displaying an image read from the memory card 14 is attached to the upper part of the main body 2 of the printer 1. The monitor 17 is a color liquid crystal, and, for example, a 1.6 inch monitor screen 18 is adopted. In the stand-alone printer 1, when an image stored in the memory card 14 is selected and printed, it is used without being connected to the PC 16, and therefore the image cannot be confirmed on the screen of the PC 16. However, by displaying a color image on the monitor screen 18 of the monitor 17, image confirmation and print layout confirmation can be performed without connection to the PC 16.

  FIG. 2 is a plan view showing the main part of the operation panel 3. In addition to the power switch 13, the operation unit 12 includes a print start switch 19, a cancel switch 20, an upper switch 21, a lower switch 22, a determination switch 23, and a return switch 24. The print start switch 19 is pressed when printing is started according to the setting conditions set on the operation panel 3, and the cancel switch 20 is set when the printing is immediately stopped when printing is being executed or when the printing is not being performed. This button is pressed when discarding the input contents (selection item, numerical value, etc.) in 10.

  The upper switch 21 and the lower switch 22 are operated when the cursor is moved on the setting screen 10 or when a numerical value is increased / decreased during numerical input. For example, when the upper switch 21 is pressed, the cursor moves upward, and the lower switch 22 is moved. When pressed, the cursor moves downward. The determination switch 23 is pressed when the display screen of the setting screen 10 is advanced one by one or when the input content on the setting screen 10 is confirmed. The return switch 24 is pressed when returning the setting screen 10 to the initial screen or when returning the display screen displayed on the setting screen 10 to the previous screen.

  FIG. 3 is a block diagram illustrating a hardware configuration and a function unit of the printer 1. The printer 1 includes a printer unit 25 and a stand-alone print unit 26 that can communicate with the printer unit 25, and the printer unit 25 includes a control device 27 and a print processing unit 28. The control device 27 controls the main control of the printer 1 and includes, for example, a CPU, a ROM, a RAM, an EEPROM, a drive circuit (not shown), and the like. On the other hand, the print processing unit 28 is a mechanical mechanism that performs print processing, and includes, for example, a recording head, a carriage motor, a paper feed motor (not shown), and the like.

  Based on the print data transmitted from the PC 16 and the image data read from the memory card 14 via the slot 15a, the control device 27 drives the print processing unit 28 to execute print processing. Here, when the image data of the memory card 14 is printed, the control device 27 performs image processing for converting the image data of the memory card 14 from RGB data to YMCK data. In this example, resolution conversion processing, color conversion processing, halftone processing, and interlace processing for rearranging the ink dot data of each color in consideration of the dot formation order are executed as image processing.

  The stand-alone print unit 26 includes a CPU 29 and a ROM 31, a RAM 32, and an ASIC 33 connected to the CPU 29 through a bus 30. The stand-alone print unit 26 includes an external I / F 34 connected to the bus 30 and a port (for example, a USB port) 35 as a connection unit connected to the external I / F 34. An external storage device (for example, MO) 36 as a storage medium is connected. Further, the operation panel 3, the monitor 17, and the slot 15a are connected to the bus 30.

  The ROM 31 stores a control program executed by the CPU 29, display data for displaying a display screen on the setting screen 10, and the like. As the control program, a display control program for controlling display on the setting screen 10 and the monitor 17, a read control program for reading image information on the memory card 14, and a storage for saving the image information on the memory card 14 in the external storage device 36. There are control programs.

  The CPU 29 controls the operation panel 3, the monitor 17, and the reading device 15, and executes these controls using the RAM 32 as a work area based on a control program stored in the ROM 31. When printing the image data of the memory card 14 is started, a desired print condition is set using the operation panel 3 and the print start switch 19 is pressed. Then, the CPU 29 transmits the image data of the memory card 14 determined by the printing conditions to the printer unit 25, and the printer unit 25 drives the print processing unit 28 based on the image data to execute the printing process on the paper.

  Further, the CPU 29 displays the image data of the memory card 14 read in the slot 15 a on the monitor 17. The display image on the monitor 17 can be switched using the operation panel 3, and the CPU 29 takes in the input conditions (layout, selected image, etc.) input on the operation panel 3, and the contents on the memory card 14 with the contents according to the conditions. The image is displayed on the monitor 17. The display format of the monitor 17 includes a single frame display that displays only one image, a multiple frame display that displays a plurality of images on the same screen, and a thumbnail display that displays a list of images on the memory card 14.

  The printer 1 can execute not only the printing process based on the image data of the memory card 14 inserted into the slot 15a but also the printing process based on the image data stored in the external storage device 36. That is, the printer 1 can directly print the image data stored in the external storage device 36. This direct printing is executed when the memory card 14 is not inserted into the slot 15a and the external storage device 36 in which a medium (for example, an MO disk) has been inserted is connected to the printer 1 (port 35).

  FIG. 4 is a memory map of the memory card 14. The memory card 14 stores image information 40 as print information captured using a digital camera (not shown). In addition to image data captured by the digital camera, the image information 40 includes various information related to image data. It is remembered. In the storage area A of the memory card 14, ID information 41 indicating that image data is stored in the memory card 14 is written. The storage area B of the memory card 14 stores address information 42 indicating from which address to which address each image is written.

  The designation information 43 is stored in the storage area C of the memory card 14. The designation information 43 is information input using a digital camera, and is information that designates, for example, an image to be printed, the number of sheets to be printed, a printing mode (index or standard), a printing order, etc. in a plurality of image data. Incidentally, a print format based on the designation information 43 is commonly called a DPOF (Digital Print Order Format) (registered trademark), and the designation information 43 is also called a DPOF file. Since the CPU 29 sets the contents of the designation information 43 as printing conditions, it is not necessary to set printing conditions on the printer 1 side, and printing can be performed with a desired printing pattern simply by setting the memory card 14 in the slot 15a of the reading device 15. Yes.

  Format information 44 is stored in the storage area D of the memory card 14. The format information 44 is one of print image formats, and is new layout information set by a user using a digital camera. The format information 44 is for determining the layout of the print image, and includes, for example, a photo frame, a line, and a macro character. A photo frame is image arrangement information, a line is line arrangement information to be printed on paper, and a macro character is image number information assigned to the photo frame. Here, the layout set in the format information 44 is an image arrangement pattern (including lines and macro characters) on one sheet of paper 8. In the format information 44, the paper type and paper size at the time of printing can also be set.

  The CPU 29 sets the content (layout, paper type, paper size) based on the format information 44 as a printing condition in preference to the content of the designation information 43. As a result, if the layout is written as the format information 44, the print layout is expanded accordingly, and printing can be performed with a layout desired by the user in addition to the layout registered in advance in the printer 1. At this time, the CPU 29 displays the image data of the memory card 14 on the monitor screen 18 with the content based on the format information 44. Although the format information 44 is set with priority over the designation information 43, the layout, paper type, paper size, and the like can be changed by operating the operation unit 12 of the operation panel 3.

A plurality of unit image information D ₁ , D ₂ ,... Are stored in the storage area E of the memory card 14. The unit image information D ₁ , D ₂ ,... Is an image file captured by the digital camera, and has image reproduction information X and image data. The image reproduction information X is information written at the time of photographing with a digital camera. When printing is performed, the image quality is corrected based on the image reproduction information X and a print image is output. The image reproduction information X includes an ID indicating the image number of the image data, a data amount of the image data, various kinds of information for setting a hue at the time of printing, brightness, sharpness, contrast, and the like, and image quality adjustment information 46. .

  Among these, the image quality adjustment information 46 is written at the time of digital camera shooting, and is correction data for making the print image as close as possible to the image shot by the digital camera. The image quality adjustment information 46 includes a γ value for controlling a gradation (color density), a color space at the time of printing, and fine image quality adjustment parameters (related to contrast, brightness, etc.). When printing is performed based on the image quality adjustment information 46, the printer unit 25 executes print processing in the image quality adjustment processing mode, and as a result, a print image is printed with an image quality according to the intention at the time of photographing with the digital camera.

  Further, the file structure of the memory card 14 is a FAT disk format, and when the image is taken with a DCF-compliant digital camera, the image data is stored in the memory card 14 in the directory format shown in FIG. That is, the directory structure has a root directory 47 at the head, and a DCF image root directory 48 and a MISC directory 49 immediately below it. The MISC directory 49 stores image information (designation information (DPOF file) 43, format information 44, image reproduction information X, etc.) other than image data.

  Directly under the DCF image root directory 48 is a DCF directory 50. The DCF directory 50 is a directory for storing DCF objects, and one manufacturer-specific one is created when an image file is saved in an external storage device. In the DCF directory 50, a directory number that does not overlap with the first three characters is written, and free characters are written in the remaining five characters. Further, a directory other than the DCF directory 50 may exist immediately below the DCF image root directory 48.

  The CPU 29 shown in FIG. 3 causes the ASIC 33 to execute backup processing for saving the image information 40 of the memory card 14 inserted into the slot 15a in the external storage device 36. As the operation procedure, the operation unit 12 of the operation panel 3 is operated to display “backup” on the setting screen 10, this parameter is selected, and the decision switch 23 is pressed. At this time, the ASIC 33 receives a control signal to that effect from the CPU 29, executes backup processing, and stores the image information 40 of the memory card 14 in the external storage device 36.

  The ASIC 33 executes a directory creation function and a storage execution function based on the control program in the ROM 31. Here, in FIG. 3, these functions executed by the ASIC 33 are shown as block diagrams of the directory creation unit 37 and the storage execution unit 38, respectively.

  Hereinafter, processing contents performed by the directory creation unit 37 and the storage execution unit 38 will be described with reference to the flowchart of FIG. In the present embodiment, the directory structure itself created in the external storage device 36 is the same as the structure shown in FIG. The present embodiment is characterized by a method for determining the name of the identification directory 51.

  As a pre-stage of the backup process, the directory creation unit 37 performs a pre-operation check (S100). As the checking process, it is confirmed whether the printer 1 is operating, whether the external storage device 36 is connected to the port 35 of the printer 1, and whether the memory card 14 is inserted in the slot 15a. Further, the data amount of the image information 40 of the memory card 14 that is the transfer source is compared with the memory capacity of the external storage device 36 that is the transfer destination, and it is confirmed whether the data can be saved. Then, if any one of these conditions is not satisfied, the directory creation unit 37 stops the backup process and causes the setting screen 10 to display that effect (for example, “backup stop”).

  On the other hand, if the condition is satisfied, the backup process is started, and the directory creation unit 37 determines the name of the identification directory 51 and creates the identification directory 51 (also referred to as a folder) in the external storage device 36 (S101).

  Here, the name determination process of the identification directory 51 to be created will be described with reference to the flowchart of FIG.

  First, the directory creation unit 37 acquires the number of identification directories 51 (see FIG. 9) created in the external storage device 36 (S200). The number of identification directories 51 can be obtained, for example, by counting the number of identification directories 51 existing under the ROOT directory 47 (see FIG. 9). Further, when the memory card 14 or the like stores the number of identification directories 51 as information, it can be obtained by referring to the information.

  When the number of identification directories 51 is acquired, the number obtained by adding 1 to the number is used as a temporary name of the identification directory 51 (S201).

  Then, it is determined whether or not the identification directory 51 can be created with a temporary name (S202). Whether or not the identification directory 51 can be created with a temporary name is checked by checking whether or not the identification directory 51 having the same name as the temporary name already exists. If not, it is determined that it can be created.

  Here, when the identification directory 51 having the same name as the temporary name exists, the identification directory 51 created in the past is deleted, and as a result, there is a vacancy in the serial number of the identification directory 51. That is, here, it is determined whether the continuity of the name of the existing identification directory 51 is maintained.

  As a result, if the identification directory 51 having the same name does not exist (S202: Y), a temporary name is determined as the name of the identification directory 51 to be created (S203).

  On the other hand, when it is impossible to create, that is, when the identification directory 51 with the same name already exists (S202: N), it is determined that there is a missing serial number in the identification directory 51, and 1 is calculated from the temporary name. The subtracted number is used as a temporary name (S204), and it is determined again whether or not the identification directory 51 can be created with the temporary name (S202). Hereinafter, this process is repeated until it is determined that the identification directory 51 can be created with a temporary name.

  By using the name of the identification directory 51 determined by this processing, the newly created identification directory 51 can fill the vacant serial number, so that the creation of the identification directory 51 is guaranteed and the external storage device Effective use is possible.

  That is, here, the name of the identification directory 51 to be created is determined so that the continuity of the name of the identification directory 51 is increased. Specifically, when there is no vacancy in the serial number, the number following the serial number is used as the name of the identification directory 51. When there is a vacancy in the serial number, any free number is used as the name of the identification directory 51. It is said.

  For example, when the identification directory 51 is “001”, “002”, “004”, “005”, and “003” is deleted, the number of identification directories 51 is four. It is determined whether the identification directory 51 can be created with a temporary name “005”.

  In this case, since “005” already exists, it is determined that it cannot be created. Next, it is determined whether the identification directory 51 can be created with a temporary name “004”. However, “004” already exists. Since it cannot be created, the temporary name is “003”.

  Then, since “003” does not exist as the identification directory 51, it is determined that it can be created, and the name of the newly created identification directory 51 is determined as “003”.

  Returning to the flowchart of FIG. 6, when the identification directory 51 having the name determined by the above processing is created (S101), the image information 40 of the memory card 14 is copied under the created identification directory 51 (S102). Then, when all the image information 40 of the memory card 14 is copied to the external storage device 36 and the storage of the image information 40 is completed, the backup process is terminated.

  In the copy process to the external storage device 36, the image information 40 having the directory structure shown in FIG. 5 stored in the memory card 14 is changed to a directory structure having the created identification directory 51 as the head, and is stored in the external storage. This is done by copying to the device 36 and storing the image data. As a result, the directory structure of the image data in the external storage device 36 is a structure in which the directory structure below the root directory of the memory card 14 to be backed up is copied directly under the created identification directory 51 (see FIG. 9).

  In addition, embodiment of this invention is not limited above, You may change into the following aspects.

  (Variation 1) In the name determination process of the identification directory 51 to be created, when it is determined that the number cannot be created when the number obtained by adding 1 to the number of identification directories 51 is a temporary name, the temporary name is “001”. It may be determined whether the identification directory 51 can be created while incrementing by one.

  (Modification 2) The transfer destination of the image information 40 of the memory card 14 is not limited to the external storage device 36. That is, as shown in FIG. 8, an internal storage device 55 connected to the bus 30 may be mounted inside the printer 1 and the image information 40 of the memory card 14 may be stored in the internal storage device 55.

  (Modification 3) The capturing of the image information 40 into the memory card 14 is not limited to a digital camera, and a mobile phone, an image browsing device (photo viewer), a scanner device, or other devices that handle images can be used. .

  (Modification 4) The identification directory 51 is not limited to being created every time saving is performed, and the creation timing of the identification directory 51 may be freely set, for example, every day.

  (Modification 5) The operation means is not limited to the button-type operation unit 12, but may be, for example, a touch panel type. The print information is not limited to the image information 40, and may be character data such as a text file. Further, the external storage device 36 is not limited to the MO, and other storage devices such as a hard disk and a semiconductor storage device may be used.

  (Modification 6) The printer 1 is not limited to the ink jet type, and may be a laser printer or the like as long as it is a stand-alone type, and the printer model is not particularly limited. The printer 1 is not limited to the structure of this example even if it is an ink jet type, and for example, a printer without the monitor 17 may be adopted.

  (Modification 7) The present invention is not limited to the identification directory name determination, but can be applied to the determination of file names and other object names.

  (Modification 8) The name of the identification directory is not limited to numbers, and a symbol group (alphabet, 50 sounds, etc.) having a regular order may be used. Moreover, it is good also as a name which added the free character string etc. to the symbol group which has a regular order.
