Description

  The present invention relates to a nameplate attached to an electronic device or the like and a battery pack having a nameplate attached thereto.

  In recent years, the display area of electronic nameplates has been increasing. The reason for this is that while electronic devices are miniaturized, many information displays such as precautions for compliance with the PL Law, recycle marks, safety standard marks, etc. are mandatory.

  In particular, in 2008, the display of the PSE mark (proof of electric products manufactured and imported in compliance with the law) has become mandatory for lithium ion secondary batteries, and the number of display items tends to increase.

  It is necessary to cope with the situation where the product is downsized and the amount of information to be displayed is increasing, but in the case of a lithium ion secondary battery, necessary information cannot be displayed within the displayable range by normal printing. Has increased.

  When the amount of information increases, various methods are described as methods for displaying information on the nameplate. In Patent Document 1, the case is formed of a transparent or translucent member, so that the nameplate display unit is provided without increasing the size of the case without increasing the size of the case. Further, Patent Document 2 describes a method of attaching nameplates using a nameplate sheet or a transfer sheet when the number of nameplates is large but the amount of information to be displayed on one nameplate is small.

  When the method as described above is used, there is a possibility that it cannot cope with further increase in the amount of information. That is, in the method according to Patent Document 1, when information is displayed immediately above the nameplate display of a transparent or semi-transparent case covering the nameplate display, the information on the top and bottom overlaps and cannot be read, increasing the amount of information. It is difficult to let In order to increase the amount of information by the method according to Patent Document 2, it is conceivable to reduce the size of the character. However, if the size of the character is reduced, it cannot be read and it is difficult to increase the amount of information.

  FIG. 4 is a bottom view of a battery pack showing a conventional nameplate. The nameplate 12 has already used the entire displayable range on the bottom surface of the battery pack 11 and has displayed precautions and a recycle mark, but there is no area for displaying a mandatory PSE mark in the future.

  As a solution for adding and displaying the PSE mark on the nameplate shown in FIG. 4, a method of adding one nameplate to the front can be considered. FIG. 5 is a diagram showing a solution for adding and displaying a PSE mark on a conventional nameplate. FIG. 5 (a) is a bottom view, FIG. 5 (b) is a front view, and FIG. 5 (c) is an upper view. A perspective view and FIG.5 (d) are bottom perspective views.

  However, in this case, the front face is the design surface, and disposing the second nameplate 13 on this surface lowers the design and limits the degree of freedom in design, resulting in inconvenience. In order to solve the above problem, it is necessary to increase the amount of information per unit area of the nameplate that can be displayed, and display it in the conventional size without adding a nameplate.

In other words, the technical problem of the present invention, without changing the size of characters and graphics, per unit area of the amount of information can be more than doubled as nameplate to provide affixed to the battery pack There is.

The battery pack of the present invention has a first display image in which the nameplate displays battery information from a first viewpoint with respect to the nameplate and a second viewpoint different from the first viewpoint with respect to the nameplate . And the second display image for displaying battery information different from the battery information of the first display image.

  The battery pack of the present invention is a battery pack in which a nameplate for displaying information such as device ratings, safety standards, recycle marks, warnings, etc. is attached to the bottom surface. The amount of information is increased more than twice.

  According to the present invention, a nameplate and a battery pack to which a nameplate is affixed can increase the amount of information per unit area more than twice by changing the image depending on the viewpoint without changing the size of characters, figures, etc. Could be provided. In addition, since it is not necessary to add a nameplate to the battery pack, it was possible to avoid a decrease in designability and freedom of design.

  Next, an embodiment of the present invention will be described with reference to the drawings for a battery pack as an example of a nameplate.

  1A and 1B are diagrams illustrating a nameplate according to the present invention, in which FIG. 1A is a perspective view of the nameplate, and FIG. 1B is an enlarged perspective view of a portion A which is an end face of the nameplate in FIG. The nameplate 12 has a substrate 16, a glue 17, a first image printing layer 18, a second image printing layer 19, and a lenticular sheet 15. The print layer 18 of the first image and the print layer 19 of the second image are alternately printed in a strip shape.

  As a method of changing the image depending on the viewpoint, holography can be used. However, it is preferable to use a lenticular sheet because switching of the display depending on the viewpoint becomes ambiguous.

  A lenticular sheet 15 in which convex lenses are regularly arranged so that only the first image can be viewed continuously when viewed from the first viewpoint 20 and only the second image can be viewed continuously when viewed from the second viewpoint 21. Is arranged on the upper surface of the nameplate 12. The first viewpoint 20 is at the upper left of the nameplate 12, and the second viewpoint 21 is at the upper right of the nameplate 12.

  The width of the print layer of the image printed in the strip shape is preferably about one half of the width of one convex lens of the lenticular sheet.

  FIG. 2 is a bottom view of the battery pack to which the nameplate of the present invention is attached. FIG. 2A is a display image of the nameplate when viewed from the first viewpoint and FIG. 2B is a view from the second viewpoint. .

  When the nameplate 12 is viewed from the first viewpoint on the upper left side of the nameplate 12, only the strip-like print layer, which is the print layer of the first image, is continuously recognized by the action of the lenticular sheet, and as a result, the nameplate 12 Can know one piece of information shown in FIG. When the nameplate 12 is viewed from the second viewpoint located at the upper right of the nameplate 12, another information shown in FIG.

  Thereby, the PSE mark 14 can be newly displayed without adding the nameplate 12. Further, by increasing the amount of information per unit area more than twice, it is possible to display information that has been conventionally required but could not be arranged, such as the forgery prevention mark 22.

  The present invention focuses on the fact that if the amount of information per unit area that can be displayed on the nameplate of an electronic device is increased, it is not necessary to add a nameplate. is there.

  The nameplate according to the present invention changes the image depending on the viewing angle due to the action of the lenticular sheet, so the amount of information per unit area that can be displayed is more than doubled compared to the conventional method without changing the size of characters and figures. It is possible to increase.

  By combining the lenticular sheet and the image printing layer, the number of viewpoints can be increased, so that it is possible to increase the amount of information per unit area that can be displayed three times or four times.

  The nameplate of the present invention can be used not only for electric products but also for other products as long as the display area is insufficient for the amount of information to be displayed.

  Examples of the present invention are described in detail below.

  In this example, a lenticular sheet having a convex lens pitch of 0.4 mm was used. The width of the printing layer of the strip-shaped image was 0.2 mm. If you look at the nameplate from the first viewpoint at the upper left of the nameplate, you can see one piece of information, and if you look at the nameplate from the second point at the upper right, you can get another piece of information. As a result, the amount of information per unit area that can be displayed can be doubled.

  3 is a perspective view of a battery pack to which the present invention is applied. FIG. 3A is an upper perspective view and FIG. 3B is a lower perspective view. The nameplate 12 has a size of 30 mm × 25 mm and is attached to the bottom surface of the battery pack 11 of 40 mm × 37 mm × 25 mm. By displaying the amount of information for two sheets on one nameplate, it was confirmed that the design was not deteriorated.

  According to the present invention, a nameplate and a battery pack to which a nameplate is affixed can increase the amount of information per unit area more than twice by changing the image depending on the viewpoint without changing the size of characters, figures, etc. Could be provided. In addition, since it is not necessary to add a nameplate to the battery pack, it was possible to avoid a decrease in designability and freedom of design.

  It can be used for a nameplate of a product whose display area is insufficient with respect to the amount of information to be displayed and a battery pack with a nameplate attached thereto.
