  As described above, according to the embodiment of the present invention, by disposing the operation button 102 on the top cover 104 of the mounting unit, there is no need to dispose the opening / closing cover on the device body as in the prior art. The quality of the device can be improved, and a space for disposing the opening / closing lid is not necessary, and the device body can be downsized.

  In the embodiment of the present invention, the memory card 103 is not necessarily a memory card as long as it is a recording medium, and may not necessarily be electrically connected as long as signals can be recorded or read out. For example, it may be an electromagnetic wave signal, a magnetic signal, or an optical signal.

  Further, the state in which the top cover 104 is closed is detected and the operation by the operation button 102 is invalidated for a predetermined time after the detection. However, while the top cover 104 is open as shown in FIG. It may be configured to invalidate the operation by 102. The control unit for controlling these may be realized by, for example, a microcomputer for system control. When these functions are not required, the storage detection SW for detecting the state where the top cover 104 is closed and the detection SW spring 120 for pressing this are not essential constituent requirements.

  In the embodiment of the present invention, the shielding lid 107 is made of a light-transmitting polycarbonate resin so that the presence of the memory card 103 can be confirmed, and is colored blue so that the presence of the card can be confirmed. The color does not necessarily have to be blue. For example, it may be green.

  Further, it is not necessary to be transparent for miniaturization, and other materials such as polyacetal may be used.

  Further, although the lid ground plate 108 made of a stainless steel plate as a conductor is fixed to the shielding lid 107, the object can be achieved without this.

  Further, the shield lid 107 and the holder base 114 are coupled by a pair of links 113 to move the shield lid 107 so that a part of the memory card 103 is exposed at the first position and covered at the second position. However, this configuration is not necessarily required. For example, the same effects can be obtained with other configurations, such as a combination of a cam and a cam follower, or moving the shielding lid 107 with a configuration using gears.

  As described above, the present invention includes a card mounting device that can be remarkably reduced in size while having high operability and dignity, and can suppress erroneous operation of equipment.
