MD42 is inserted into the case from the entrance 45 and loaded.
Alternatively, the MD 42 can be easily taken in and out simply by pulling the MD 42 out of the case against the elastic force of the lock body 46. The problem is that the index card is attached so that it covers the outer surface of the storage case at the time of sale.Therefore, if the packaging film is opened and discarded, there is no storage space for the index card, and the index card is not used until the title label is used. The card has to be stored separately and is easily lost. It is not impossible to store the entire card in the storage case by cutting off the periphery of the index card, but it is not easy to put the index card in and out because the vertical distance between the entrance and exit 45 is as small as 5 to 6 mm. Absent. When the index card is taken in and out, a disadvantage that a part of the card is caught by the lock body 46 inside the case cannot be avoided. Further, it is inconvenient to take in and out the MD 42 itself using the entrance 45.
