Description

  The present invention relates to a storage case for storing a total type wheel used for molding a memory card.

  A memory card such as an SD card (registered trademark) used by being inserted into a card slot of various electronic devices is formed by mounting a plurality of memory elements on a wiring board and covering with a mold resin.

  In such a memory card, memory elements are mounted on a single wiring board in a grid pattern, and the whole is covered with a mold resin to form a package substrate. Then, a region between the memory elements on the package substrate is cut and separated. Is formed.

  By the way, the shape of the memory card is standardized, and when the memory card is inserted into the card slot, the side portion facing the side wall of the card slot can be recognized in the front and back and the front and rear direction at the time of insertion. For this reason, a deformed portion is formed. Chamfering is applied to the corners where the deformed part is not formed.

Thus, in order to facilitate the processing of the outer shape of a memory card having a relatively complicated outer shape in order to avoid incorrect insertion into the card slot, the applicant of the present invention has previously used a general-purpose wheel. An attached memory card processing apparatus was developed and a patent application was filed (see Japanese Patent Application Laid-Open No. 2008-112253).

  However, there is no storage case for storing the general-purpose wheel, and there is a problem in that the general-purpose grindstone formed on the outer periphery of the general-purpose wheel may be damaged during conveyance of the general-purpose wheel.

  This invention is made | formed in view of such a point, The place made into the objective is providing the total type | mold wheel accommodation case suitable for accommodating and conveying a total type | mold wheel.

  According to the present invention, there is provided a housing case for housing a general-purpose wheel having a general-purpose grindstone on the outer periphery of a cylindrical base and having an opening at the center of the cylindrical base, and surrounds the outer periphery of the general-purpose wheel. It has a cylindrical side wall, a bottom wall that closes the lower part of the cylindrical side wall, and a convex part that is erected from the central part of the bottom wall and fits into the opening of the central part of the column base. A box, a lid detachably mounted on the opened top of the box, a first buffer sheet laid on the bottom wall so as to cover the convex portion, and a lay on the lid And a second cushioning sheet, and a housing case for housing the total type wheel.

  According to the present invention, by storing and transporting the general-purpose wheel in the storage case, it can be transported without damaging the general-purpose grindstone formed on the outer periphery of the cylindrical base.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. Referring to FIG. 1, there is shown an exploded perspective view of a housing case that houses a general wheel according to an embodiment of the present invention.

  The total-type wheel (total-type blade) 2 is configured by electrodepositing a total-type grindstone 6 on the outer periphery of a cylindrical base 4 made of, for example, an aluminum alloy. The total type grindstone 6 is configured by electrodepositing and fixing superabrasive grains such as diamond abrasive grains by nickel plating or the like.

  The general-purpose grindstone 6 has a complicated outer peripheral shape as disclosed in Patent Document 1, for example, and has a shape suitable for forming the outer shape of the memory card into a desired shape. A circular opening (mounting hole) 8 to be mounted on the spindle of the processing apparatus is formed at the center of the column base 4.

  The housing case 10 for housing the overall wheel 2 is provided with a cylindrical side wall 14 that surrounds the outer periphery of the overall wheel 2, a bottom wall 16 that closes a lower portion of the cylindrical side wall 14, and a central portion of the bottom wall 16. The box 12 has a convex portion 18 that fits into the circular opening at the center of the cylindrical base 4 of the mold wheel 2, and the box 12 that is open at the top and the open top of the box 12 are detachably closed. And a lid 22.

  As best shown in FIG. 2, a first buffer sheet 20 is laid on the bottom wall 16 of the box 12 so as to cover the convex portion 18, and a second buffer sheet 24 is disposed in the lid 22. Is laid. The first and second buffer sheets 20 and 24 are made of, for example, rubber, porous material, soft synthetic resin, or the like.

  In order to store the total type wheel 2 in the storage case 10, the circular opening 8 of the total type wheel 2 is fitted into the convex portion 18 of the box 12 of the storage case 10 and stored in the box 12. 3, the lid body 22 is attached to the box body 12.

  If necessary, the overall wheel 2 is accommodated in the accommodating case 10 by being taped at the entire circumference or in the circumferential direction of the joint between the box 12 and the lid 22 and transported or stored. can do.

  Since the total-type wheel 2 is protected by the first and second buffer sheets 20 and 24 and is stored in the storage case 10, the total-type grindstone 6 is prevented from being damaged when the total-type wheel 2 is conveyed. The

It is a disassembled perspective view of the storage case which stores the total type wheel which concerns on this invention embodiment. It is a longitudinal cross-sectional view of a storage case. It is a perspective view of the storage case of the state which attached the cover to the box.
