BACKGROUND OF THE INVENTION 
   1. Field of the Invention 
   The present invention relates to an electronics device, a replacement part for the electronics device, and a package of the replacement part, and especially to an electronics device, a replacement part for the electronics device, a package of the replacement part each comprising an identifying section for specifying/determining information on the content, etc., and a method for arranging identifying section. 
   2. Description of the Related Art 
   In Unexamined Japanese Patent Application KOKAI Publication No. H6-336030, a color inkjet printer or a color copying machine comprising a structure where an ink cartridge can be attached or moved to/from a storing unit, is disclosed. At the outer packaging box of these ink cartridges, information indicating the content, for example, information indicating what color of ink that ink cartridge stores, is written by a visual method, such as a number or note of the color, etc. 
   As described above, information on the content is written on the outer packaging box of the ink cartridge, only by a visual method. Therefore, for example, it is difficult for a visually impaired person to obtain information on the content, from an un-opened outer packaging box. Also, in such a case that an ink cartridge should be replaced at a dark place, it is difficult for even a person not visually impaired to adequately select the ink cartridge required for the replacement. 
   Further, in many cases, in addition to the outer packaging box, the ink cartridge is wrapped by a plastic inner packaging etc., for keeping the high air-tightness for the cartridge and protecting the cartridge as content. Therefore, it is convenient if the information on the content can be obtained without opening the inner packaging. 
   Also, as to a case where replacement parts similar in their shapes or the like are handled, for example, a case where ink cartridges different in the colors of their contained inks are to be put on their carriages, the person who handles these replacement parts sometimes cannot decide the relation between each of the parts and each of the setting positions corresponding to each of the parts. And in such cases, it is inconvenient to handle the replacement part.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   An electronics device, a replacement part thereof, and a package of the replacement part will be described with reference to the drawings, by employing as examples, a color printer, an ink cartridge, and an outer packaging box of the ink cartridge. 
   An outer packaging box  2  according to the present embodiment is a package for packaging an ink cartridge  3 . As shown in  FIG. 1 , the ink cartridge  3  is used by being taken out from the outer packaging box  2 , and being inserted into a predetermined portion in a cartridge setting section  4  of a carriage of a color printer  1 . 
   As shown in  FIG. 2A  through  FIG. 2D , the outer packaging box  2  comprises a round-shaped perforation/perforations (an identifying section for identifying the type of the content) positioned at a predetermined position ( 21  in  FIG. 2A  through  FIG. 2D ) on the front surface. The outer packaging box  2  includes at least one perforation. The number of perforations indicates the color of the ink of the ink cartridge  3 , which is the content of the outer packaging box  2 . More specifically, the number of perforations corresponds to the color of each ink, in a way such as, one perforation=black ink, two perforations=cyan ink, three perforations=magenta ink, and four perforations=yellow ink. The perforation/perforations has/have a size large enough and an interval relative to the others large enough to enable the user of the ink cartridge  3  to identify the number of perforation/perforations when he/she directly touches the corresponding portion ( 21  in  FIG. 2A  through  FIG. 2D ) of the outer packaging box  2 . 
   As shown in  FIGS. 3A and 3B , the ink cartridge  3  comprises a round-shaped convex shape or convex shapes (an identifying section for identifying the type of the ink) at a predetermined position ( 31  in  FIG. 3A ,  FIG. 3B ) on the front surface.  FIG. 3A  is a front view of the ink cartridge  3 , and  FIG. 3B  is a cross-sectional view of the ink cartridge  3  when it is sectioned along a chain line A-A of  FIG. 3A . The number of convex shapes indicates the color of the ink of each ink cartridge  3  and corresponds to the color of each ink one to one such as, one convex shape=black ink, two convex shapes=cyan ink, three convex shapes=magenta ink, and four convex shapes=yellow ink, in the same way as the case of the perforation/perforations in the outer packaging box  2  above described. The convex shape/shapes has/have an area and height large enough and an interval relative to the others large enough to enable the user to identify the number of convex shape/shapes when he/she directly touches the corresponding portion ( 31  in  FIG. 3A ,  FIG. 3B ) of the ink cartridge  3 . 
   The cartridge setting section  4  comprises a round-shaped convex shape/shapes (convex section) at the portion below an ink cartridge inserting section  41  ( 42  in  FIG. 4A ,  FIG. 4B ), as shown in  FIGS. 4A and 4B .  FIG. 4A  is a front view of the cartridge setting section  4 , and  FIG. 4B  is a cross-sectional view of the cartridge setting section  4  when it is sectioned along a chain line B-B of  FIG. 4A . 
   The number of convex shapes indicates the color of the ink of a corresponding ink cartridge  3  to be inserted into the ink cartridge inserting section  41 , and corresponds to the color of each ink one to one such as, one convex shape=black ink, two convex shapes=cyan ink, three convex shapes=magenta ink, and four convex shapes=yellow ink, in the same way as the case of the convex shape/shapes of the ink cartridge  3  above described. 
   Also, the convex shape/shapes of the cartridge setting section  4  has/have a size large enough and an interval relative to the others large enough to enable the user of the ink cartridge  3  to identify the number of convex shape/shapes when he/she directly touches the portion below the ink cartridge inserting section  41  ( 42  in  FIG. 4A ,  FIG. 4B ). 
   As described above, each of the ink cartridge  3 , the outer packaging box  2 , and the cartridge setting section  4  of the color printer  1  according to the present embodiment, comprises a convex shape/shapes (convex section) or a perforation/perforations that corresponds/correspond to the color of each ink. Thereby, the user can identify the ink cartridge  3  required for replacement and the position in the cartridge setting section  4  where the ink cartridge  3  is to be inserted, only by his/her feelings got by the touch with his/her hands. 
   The perforation/perforations of the outer packaging box  2 , the convex shape/shapes of the ink cartridge  3 , and the convex section of the cartridge setting section  4  correspond to each other, by the color of the ink. Therefore, even in a case where the user does not know which color the convex shape or the perforation indicates, the user can replace the ink cartridge  3 , by identifying each shape with tactile sense. 
   Therefore, according to the present invention, replacement of a replacement part such as an ink cartridge, etc., which is difficult for a visually impaired person, etc., can be carried out smoothly. Also, for people who are not visually impaired, replacement of a replacement part can be carried out smoothly, in a case where the device is placed at a place where visibility is poor, such as on a shelf, at a dark place, or on the floor under a desk, etc. 
   The present invention is not limited to the above embodiment, and various changes and modifications are possible. 
   For example, in the above embodiment, it is described that an identifying section that comprises a round-shaped perforation or a group of perforations, or a convex shape or a group of convex shapes is respectively provided at the outer packaging box  2 , the ink cartridge  3 , and the cartridge setting section  4 . However, the shape for the identifying section is not limited to a round-shape, a perforation, and a convex shape. The shape may be formed in the shape of, for example, a star or a triangle, a depressed state, or a slit, etc. so that the shapes can be identified by tactile sense. Also, it is not necessary that the outer packaging box  2 , the ink cartridge  3 , and the cartridge setting section  4  have the same shape. The shapes may be different as long as each shape is associated with a specified color. For example, a structure is available where alphabets such as, “B”, “C”, “M”, and “Y”, which are the initial letters of Black, Cyan, Magenta, and Yellow, are provided in a convex shape that can be identified by tactile sense, on the surface of the outer packaging box, while words such as “BLACK”, “CYAN”, “MAGENTA”, and “YELLOW”, which represent the colors, are provided in a convex shape that can be identified by tactile sense, on the cartridge setting section  4 . Namely, identifying sections having outer shapes (shape, size, number, etc.) that can be recognized by the tactile sense of a person as being the same or as being corresponding, may be provided. 
   In the above embodiment, an example where the present invention is applied to a printer of an ink-jet-printing type, an ink cartridge, and the package of the ink cartridge, is shown. However, the printing method of the printer to which the present invention is applied, is not limited to the type above described, and for example, the present invention may be applied to a printer adopting another printing method, such as a laser printer using toner, or a thermal transfer printer using an ink ribbon, etc. Also, the shapes of the ink cartridge  3  and the cartridge setting section  4  (shape of the identifying section) to which the present invention is applied, are arbitrary.  FIG. 5  shows an example of applying the present invention to a toner cartridge  3 A of a laser printer, and a cartridge setting section  4 A of a toner cartridge. The toner cartridge setting section  4 A is a revolver type toner cartridge setting section  4 A that rotates in a direction of an arrow YA shown in the drawing. As shown in  FIG. 6A , the toner cartridge setting section  4 A comprises four toner cartridge inserting sections  41 A. Each toner cartridge inserting section  41 A comprises a hemicyclic slit or slits (identifying section) at the edge of the inserting opening of each toner cartridge inserting section  41 A. The number of slits indicates the color of the toner of the toner cartridge  3 , that is to be inserted to each toner cartridge inserting section  41 A. The number of slits corresponds to the color of the toner one to one, in such a way as, one slit=black, two slits=cyan, three slits=magenta, and four slits=yellow. As shown in  FIG. 6B , the toner cartridge  3 A has a cylindrical shape, and comprises a round convex shape/shapes at the base (front end shown in the perspective view of  FIG. 6B ). The number of convex shapes indicates the color of the toner of each toner cartridge  3 A, and corresponds one to one, to the color of the toner, such as one convex shape=black, two convex shapes=cyan, three convex shapes=magenta, and four convex shapes=yellow. Also, as shown in  FIG. 6C , the outer packaging  2 A that stores the toner cartridge  3 A comprises a round-shaped perforation or perforations positioned at a predetermined position on its surface. The number of perforations indicates the color of the toner of the toner cartridge  3 A that is to be the content of the outer packaging  2 A, and corresponds to the color of the toner one to one, such as one perforation=black, two perforations=cyan, three perforations=magenta, and four perforations=yellow. In this way, irrespective of the printing method and shapes of the cartridge and the cartridge setting section, by providing a three dimensional shape that can be identified by tactile sense, to the outer packaging box  2 A, the toner cartridge  3 A, and the toner cartridge inserting section  41 A, a printer wherein the user can replace the cartridge by tactile sense, is realized. 
   In the above embodiment, an example where the present invention is applied to a color printer  1  and an ink cartridge  3  used for the color printer  1 , is shown. However, the present invention can be applied to other things. For example, the present invention can be applied to a vending machine for soft drinks as follows. A soft-drink can, a box for packaging the soft-drink can and a refilling opening from which canned soft drinks are refilled to a vending machine, are provided with a shape that can be identified by a person with his/her tactile sense at their predetermined positions. This makes it possible to refill the canned soft drinks as merchandise to the vending machine under a bad visible condition. 
   Various embodiments and changes may be made thereunto without departing from the broad spirit and scope of the invention. The above-described embodiment is intended to illustrate the present invention, not to limit the scope of the present invention. The scope of the present invention is shown by the attached claims, rather than the embodiment. Various modifications made within the meaning of an equivalent of the claims of the invention and within the claims are to be regarded to be in the scope of the present invention. 
   This application is based on Japanese Patent Application No. 2003-388820 filed on Nov. 19, 2003 and including specification, claims, drawings, and summary. The disclosure of the above Japanese Patent Application is incorporated herein by reference in its entirety.
