When the locked state of b, 12b is released, the upper end rotates by its own weight so as to contact the housing 5. Also,
The upper end and the lower end of the lid 22 are an opposite pivot end and a pivot end, respectively.

Reference numeral 32 denotes a card storage space 32a into which a part of the memory card 33 can be inserted and removed, and a card storage space 3a.
A memory card connector having lead pins 32b facing inside 2a. The memory card connector is rotatably held by the connector holder 13 via the second shaft 18, and the sealing member 10 in the recess 4 is opened and closed by opening and closing the lid 22. It is configured to be able to go in and out. At the lower end of the memory card connector 32, there is provided a convex portion 34 through which the second shaft 18 is inserted and faces between the two second holders 15. The convex portion 34 has a spring opening on the back side of the connector. An L-shaped locking recess 34b, which is open in the same direction as the opening direction of the storage space 34a and the spring storage space 34a, is provided. On one side of the memory card connector 32, a guide portion 35 having a connector rotation restricting hole 35a facing the stopper pin 16 is provided.

The connector rotation restricting hole 34a of the guide piece 35 is formed by an arc-shaped opening such that the memory card connector 32 rotates approximately 45 degrees in the opening direction. On the back side of the memory card connector 32, a card board 36 connected to the lead pins 32b is mounted.

Numeral 37 denotes a torsion spring for applying a turning force to the memory card connector 32 in the outward direction.
It is provided around the shaft 18 and both ends are locked by the locking recesses 14b and 34b.

Note that reference numeral A in the figure denotes a plane of the memory card connector 32.

In the memory card attaching / detaching device of the electronic apparatus thus configured, the memory card 33 is connected to the main body 1.
The memory card 33 is connected to the lead pins 32b of the memory card connector 32 and is stored in the recess 4 of the housing 5.

In this case, first, the lid 22 is rotated in the opening direction by the finger of the operator to release the locked state of the claw portions 28, 29 and the locking bent portions 11b, 12b. At this time, the memory card connector 32 rotates by 45 ° in the opening direction following the rotation of the lid 22 due to the resilience of the torsion spring 37, and the recess 4 of the housing 5.
Exposed outside. Further, since the lid 22 and the memory card connector 32 draw different rotation trajectories, the protrusion 3
0 and 31 slide on the plane A of the memory card connector 32. Next, a part of the memory card 33 is inserted into the card storage space 32a of the memory card connector 32. Thereafter, the lid 22 is rotated in the closing direction against the elasticity of the torsion spring 37. At this time, the memory card connector 32 faces the concave portion 4 of the housing 5, and the claw portions 28, 29 of the lid 22 engage with the locking bent portions 1 of the locking pieces 11, 12.
1b and 12b.

Thus, the memory card 33 can be mounted on the main body 1.

On the other hand, in order to remove the memory card 33 from the main body 1, the memory card connector 32 is exposed outside the recess 4 of the housing 5, and the memory card connector 32
This is performed by taking out the memory card 33 outside.

In this case, first, the lid 22 is rotated in the opening direction by the operator's finger to release the locked state of the claw portions 28, 29 and the locking bent portions 11b, 12b. At this time, the memory card connector 32 rotates by 45 ° in the opening direction following the rotation of the lid 22 due to the resilience of the torsion spring 37, and the recess 4 of the housing 5.
Exposed outside. Further, since the lid 22 and the memory card connector 32 draw different rotation trajectories, the protrusions 30 and 31 slide on the plane A of the memory card connector 32. Next, the memory card connector 3
The memory card 33 is pulled out of the second card storage space 32a. In this way, the memory card 3
3 can be disengaged.

The lid 22 and the housing 5 are connected to each other by the locking bent portion 11.
Since the electrical connection is established by the engagement of the claws 28 and 29 with the b and 12b, the electromagnetic waves inside and outside the housing 5 can be cut off when the lid is closed.

Further, when the lid is closed, a part of the connector storage space between the lid 22 and the housing 5 can be surrounded by the seal member 10, so that an effect conforming to the drip-proof standard can be obtained.

Furthermore, since the constituent parts can be unitized, the assemblability for electronic equipment can be improved, and the number of design steps when changing the model can be reduced.

In addition, when the cover is closed, the memory card holder 19 is closed.
As a result, it is possible to prevent the memory card 33 from being detached from the memory card connector 32, so that the vibration resistance and the shock resistance can be improved.

FIGS. 7 and 8 show the memory card 33 and the memory card holder 51 of the present invention.

The memory card 33 has a lead hole (terminal) (not shown) at one end in a direction orthogonal to the insertion / extraction direction, and a hole 33b for insertion / extraction at the other end. A retaining recess 33 is provided on at least one side in the extending direction.
a and a groove 33c extending in the insertion / removal direction for preventing erroneous insertion.

The memory card holder 51 is for enhancing the portability of the memory card 33, and includes a card storage space 51a having a card insertion opening opened on one side and an opening for inserting the card in the card storage space 51a. A hole 51 for attaching a key holder which penetrates the upper and lower surfaces at the opposite end and at a position deviating from the card storage space 51a.
b is provided. The above memory card holder 51
Is made of a conductive resin or an electrostatic breakdown preventing material (electromagnetic shielding material) made of a conductive material in which stainless steel is adhered to a material such as an ABS resin. Inside the card holder 51, an elastically deformable drip-proof / dust-proof rubber sheet 52 that covers the opening of the lead hole of the memory card 32 when the card is stored is affixed. On both side edges of the card holder 51, elastic pieces 53 and 54 are provided integrally, which engage with and hold the retaining recesses 33a provided on both sides of the memory card 33 when the card is stored. ing. These elastic pieces 53 and 54 are set at the same position in the card insertion direction, and set at different positions in the card thickness direction.
