The present invention relates to a memory card incorporating a write/nonwrite setting means for preventing erroneous erasure or erroneous rewriting of a stored content.
Conventionally, in some memory cards, a reflective sheet, a switch, or a setting element which is largely exposed from a main body have been used as a write/nonwrite setting means.
FIG. 12 is a perspective view showing a conventional memory card 1100 incorporating a write/nonwrite setting means which is realized by a reflective sheet 33. In FIG. 12, reference numeral 31 denotes a main body of the memory card, reference numeral 32 denotes a terminal which is integrally formed with the main body 31 of the memory card, and reference numeral 33 denotes a reflective sheet.
FIG. 1 is a perspective view showing a lower surface side of an assembled memory card according to embodiment 1 of the present invention.
FIG. 2 is a perspective view showing the memory card according to embodiment 1 of the present invention, in which a lower main body is partially cut away.
FIG. 3 is a perspective view showing an upper surface side of a partially-exploded memory card according to embodiment 1 of the present invention.
(Embodiment 1)
Hereinafter, embodiment 1 of the present invention is described with reference to the drawings.
FIG. 1 is a perspective view showing a lower surface side of an assembled memory card 100 according to embodiment 1 of the present invention. FIG. 2 is a perspective view showing the memory card 100 in which a lower main body is partially cut away. FIG. 3 is a perspective view showing an upper surface side of the partially-exploded memory card 100. FIG. 4 is a perspective view showing the memory card 100 in which an upper main body is partially cut away. FIG. 5 is a cross-sectional view showing the memory card 100 taken along line A-A in FIG. 1. FIGS. 6(a) and 6(b) illustrate manipulation of a write/nonwrite setting element of the memory card 100. FIGS. 7(a) and 7(b) illustrates detection of the setting of the write/nonwrite setting element in the memory card 100.
