Therefore, the metal plate 9 and the magnet 21 function as a closed state holding unit that holds the lid 18 in the closed position.

  As described above, by providing the electronic device 1 with the closed state holding means, the lid 18 can be reliably and easily held at the closed position.

  When the lid 18 is in the closed position, the oscillating body 13 is held at a position farthest from the inner surface 3 a of the side panel 3. At this time, the stopper portion 14b of the rocking body 13 and the stopper portion 12 of the side panel 3 are not in contact with each other.

  When the lid 18 is in the closed position, the arm portions 20 and 20 of the lid 18 protrude toward the inner surface 3a side of the side panel 3 through the insertion holes 8a and 8a.

  When the lid 18 is opened and rotated in the R1 direction shown in FIG. 6 with respect to the rocking body 13, the rocking body 13 simultaneously moves in the R1 direction with respect to the side panel 3 by the biasing force of the biasing springs 17 and 17. The connecting protrusions 16 and 16 of the rocking body 13 are protruded outward (rightward) from the opening 6a (see FIG. 7). At this time, the arm portions 20 and 20 of the lid 18 are in contact with the opening edge of the opening 6a of the side panel 3, respectively, and the lid 18 is rotated with respect to the side panel 3 with the portion in contact with the opening edge as a fulcrum. The Accordingly, the arm portions 20 and 20 of the lid body 18 also function as fulcrum portions 20A and 20A that serve as rotation fulcrums with respect to the side panel 3.

  When the arm portions 20 and 20 function as the fulcrum portions 20A and 20A and the lid body 18 is rotated, the connecting projections 16 and 16 of the rocking body 13 are further outward from the opening 6a along with the rotation operation. It is projected to.

  When the lid 18 is further opened and rotated in the R1 direction shown in FIG. 7 with respect to the swinging body 13, the swinging body 13 is continuously rotated in the R1 direction with respect to the side panel 3, and the swinging body 13 is covered. The stopper portion 14b comes into contact with the stopper protrusion 12 of the side panel 3, and further rotation of the rocking body 13 is restricted (see FIG. 8). At this time, the arm 18 and 20 of the lid 18 are separated from the opening edge of the opening 6a.

  In a state where the stopper portion 14b of the oscillating body 13 is in contact with the stopper projection 12 of the side panel 3 and the rotation of the oscillating body 13 is restricted, the support shafts 16a and 16a of the coupling projections 16 and 16 are opened.

The stand 32 is supported by the display panel 29 with one end 32a inserted between the stopper rib 30a and the urging force applying portion 30b.

  Hereinafter, the rotation operation of the display panel 29 will be described (see FIGS. 13 to 17).

  When the display panel 29 is in the closed position housed in the panel housing recess 22, as shown in FIG. 13, the stand 32 is located close to the back surface of the display panel 29, and the sliding engagement portion 34, 34 is located in the rear concave portion 25b of the holding portion 25. This position of the stand 32 is an engagement preparation position.

  When the display panel 29 is rotated from the closed position, the sliding engagement portions 34 and 34 of the stand 32 are inserted into the guide portions 28 and 28 from the rear concave portion 25b, and the other end portion 32b is the second portion of the holding portion 25. The first surface portion 25c is moved. At this time, when the rotation of the display panel 29 is stopped at an arbitrary position, the other end portion 32b of the stand 32 is engaged with one of the holding grooves 26 formed in the holding portion 25, and the display panel 29 is moved to a desired angle. Can be held in.

  When the display panel 29 is further rotated, the sliding engagement portions 34, 34 of the stand 32 reach the front end portions of the flange walls 27, 27, respectively, and the one end portion 32a of the stand 32 contacts the biasing force applying portion 30b. (See FIG. 15). When the display panel 29 is slightly rotated from this state in the opening direction, the sliding engagement portions 34 and 34 are engaged with the front end edges of the flange walls 27 and 27, respectively, and the biasing force applying portion 30b is used as a reference. The stand 32 is slightly bent and elastically deformed. Therefore, a biasing force is applied to the stand 32 in a direction (upward) in which the sliding engagement portions 34 and 34 are separated from the guide portions 28 and 28.

  When the display panel 29 is further rotated in the opening direction from the state in which the stand 32 is elastically deformed, the engagement of the sliding engagement portions 34 and 34 with the flange walls 27 and 27 is released, and the stand 32 is elastically restored.

  An insertion restricting body 50 is rotatably supported on the front surface portion 49. The insertion restricting body 50 includes a supported surface portion 51 that is long to the left and right, supported protrusions 52 and 52 that protrude rearward from both left and right end portions of the supported surface portion 51, and a central portion in the left and right direction of the supported surface portion 51. A projecting portion 53 projecting obliquely downward from the front, a projecting portion 54 projecting downward from the lower edge of the projecting portion 53, and a first projecting portion projecting left or right from the projecting portion 54. The first action part 55 and the second action part 56 are integrally formed.

  A fulcrum shaft 51a that protrudes rearward is provided at the center of the supported surface 51 in the left-right direction.

  The supported protrusions 52 and 52 are formed in a gently arcuate shape that protrudes outward, and engaging claws 52a and 52a that protrude outward are provided at the rear ends.

  The first action part 55 projects leftward from the lower end part of the projecting part 54, and the second action part 56 projects rightward from the upper end part of the projecting part 54. An inclined surface 55a that is displaced rearward as it goes to the left is formed at the left end of the first action part 55, and an inclined surface 56a that is displaced rearward as it goes to the right is formed at the second action part 56. ing.

  In the insertion restricting body 50, the fulcrum shaft 51a is inserted into the fulcrum hole 49b of the chassis 47, and the supported protrusions 52 and 52 are inserted into the support holes 49a and 49a, respectively, and engage with the opening edges of the support holes 49a and 49a. By engaging the claws 52a and 52a, the claw 52a and 52a are rotatably supported by the front surface portion 49 with the fulcrum shaft portion 51a as a fulcrum. In a state where the insertion restricting body 50 is supported by the front surface portion 49, the protruding portion 54 is positioned immediately in front of the circuit board 40.

  The operation of the insertion restricting body 50 when the storage media 100 and 200 are mounted in the mounting slots 43 and 44 will be described below (see FIGS. 19 to 21).

  The insertion restricting body 50 is held in a neutral position by its own weight in a state where the storage media 100 and 200 are not inserted into any of the mounting slots 43 and 44 (see FIG. 19). The neutral position is a position where the supported surface portion 51 extends in the horizontal direction and the connecting portion 53 and the protruding portion 54 extend in the vertical direction. In the neutral position, the insertion restricting body 50 is such that the left end portion of the first action portion 55 is positioned on the front side of the right end portion of the mounting slot 43, and the right end portion of the second action portion 56 is the front side of the left end portion of the mounting slot 44. Located in.

  When the storage medium 100 is inserted into the mounting slot 43 through the insertion port 36, the front edge of the right end portion of the storage medium 100 comes into sliding contact with the inclined surface 55a of the first action portion 55, and the insertion restricting body 50 is anti-reverse. It is rotated in the clockwise direction (S1 direction shown in FIG. 19) (see FIG. 20). Therefore, the shielding amount by the second action part 56 for the mounting slot 44 is increased.

  When the storage medium 100 is inserted into the mounting slot 43 and mounted, the left side edge of the first action portion 55 is in contact with the right side surface of the storage medium 100, and the insertion restricting body 50 is rotated in the clockwise direction (FIG. 20). And the state in which the shielding amount by the second action portion 56 with respect to the mounting slot 44 is increased is maintained. Therefore, the second action part 56 also functions as a shielding part 56A that shields a part of the mounting slot 44. Even if the storage medium 200 is inserted from the mounting slot 44 via the insertion port 37, the left end of the storage medium 200 The portion is brought into contact with the front surface of the second action portion 56, and insertion into the mounting slot 44 is restricted.

  Even if the front surface of the second action part 56 is pressed by the storage medium 200 at this time, the second action part 56 is in contact with the front edge of the circuit board 40, so that excessive deformation of the second action part 56 is prevented. The

  When the storage medium 100 is pulled out from the mounting slot 43, the restriction on the rotation of the insertion restricting body 50 in the S2 direction by the storage medium 100 is released, and the insertion restricting body 50 returns to the neutral position by its own weight (see FIG. 19).

  On the other hand, when the storage medium 200 is inserted into the mounting slot 44 through the insertion port 37, the front edge of the left end portion of the storage medium 200 comes into sliding contact with the inclined surface 56a of the second action portion 56, and the insertion restricting body 50 is inserted. Is rotated in the S2 direction (see FIG. 21). Therefore, the shielding amount by the first action part 55 with respect to the mounting slot 45 is increased.

  When the storage medium 200 is inserted and mounted in the mounting slot 44, the right side edge of the second action part 56 is in contact with the left side surface of the storage medium 200, and the insertion restricting body 50 rotates in the S1 direction. Is restricted, and the state in which the shielding amount by the first action portion 55 with respect to the mounting slot 43 is increased is maintained. Therefore, the first action part 55 also functions as a shielding part 55A that shields a part of the mounting slot 43. Even if the storage medium 100 is inserted from the mounting slot 43 through the insertion port 36, the right end of the storage medium 100 The portion is brought into contact with the front surface of the first action portion 55, and insertion into the mounting slot 43 is restricted.

  Even if the front surface of the first action part 55 is pressed by the storage medium 100 at this time, the first action part 55 is in contact with the front edge of the circuit board 40, so that excessive deformation of the first action part 55 is prevented. The

  When the storage medium 200 is pulled out from the mounting slot 44, the restriction on the rotation of the insertion restriction body 50 in the S1 direction by the storage medium 200 is released, and the insertion restriction body 50 returns to the neutral position by its own weight (see FIG. 19).

  As described above, in the electronic apparatus 1, the insertion restriction body 50 that can be rotated is selectively prevented from being inserted into the mounting slot 43 of the storage medium 100 or the mounting slot 44 of the storage medium 200. With this mechanism, it is possible to prevent the storage media 100 and 200 from being simultaneously inserted into the two mounting slots 43 and 44 without increasing the size of the electronic device 1.

  Further, when the storage medium 100, 200 is not inserted into any of the mounting slots 43, 44, the insertion restricting body 50 is held at the neutral position by its own weight, so that the insertion restricting body 50 is held at the neutral position by its own weight. Therefore, it is possible to simplify the mechanism.

  Furthermore, since the insertion restricting body 50 also functions as shielding portions 55A and 56A that shield the portions of the mounting slots 43 and 44, respectively, the first acting portion 55 and the second acting portion 56 are provided with separate shielding portions. There is no need, and the mechanism can be simplified and the number of parts can be reduced.

  In the above example, the insertion restricting body 50 is held at the neutral position by its own weight. For example, the chassis 47 and the insertion restricting body 50 are connected by a spring, and the storage media 100 and 200 are mounted in the mounting slots 43 and 44. It is also possible to hold the insertion restricting body 50 in the neutral position when it is not inserted.
