Some display devices are set to a desired display angle by the frictional force of the frictional locking member in contact (see, for example, Patent Document 1). In addition, the applicant could not find any prior art documents closely related to the present invention by the time of filing other than the prior art documents specified by the prior art document information described in the present specification. .
Japanese Patent Application No. 2003-054470 (paragraph “0021”, FIG. 7)

  In the conventional display mounting structure described above, the friction locking member is always pressed by the locked portion, so that the display angle is set to 0 ° by lying down on the display mounting portion. Sometimes, the friction locking member is pressed by the locked portion and is elastically deformed. For this reason, when the display is lowered from the state in which it has occurred, an elastic return force is generated in the friction lock member due to the elastic deformation of the friction lock member. There was a problem that it slightly rotated in the direction of getting up and did not completely fall down. Further, since the housing of the electronic device has a structure in which an opening that allows the locked portion of the display device to protrude and retract is provided, there is a problem that dust enters the housing from this opening. Furthermore, since the display unit and the display unit mounting part come into contact with each other when the display unit falls down, the display unit mounting unit is likely to be damaged, and the appearance of the device housing is impaired.

As will be described later, these stepped portions 23a and ribs 23b are arranged so that the front end portion of the frictional locking member 40 is located when the display unit 14 is in a lying state on the display unit mounting recessed portion 7 and the display angle is set to 0 °. It is positioned at a position where it engages with the step portion 23a and the rib 23b.

  Engaging portions 24 and 24 are integrally projected at the ends of the large diameter portions 20 and 20 in the direction of arrow D. A groove 25 is formed in the back surface 15 so as to surround the locked portion 18 and is formed in a U-shape in plan view, and the display device 14 falls on the recessed portion 7 for mounting the display device. The wall 37 of the bracket 30 to be described later faces the groove 25 when being in contact. Numerals 26 and 26 are low-height convex portions integrally projecting on the back surface 15 side of the display 14, and extend in the direction of the arrow CD at both ends of the end in the direction of the arrow C. When 14 falls to the display unit mounting recessed portion 7, it comes into contact with the convex portion 11 of the display unit mounting recessed portion 7 so as to be orthogonal to each other.

  In FIG. 6, reference numeral 30 denotes a bracket made of plastic, and is formed in a U shape in a plan view by a base portion 31 and a pair of side portions 32, 32 protruding from both ends of the base portion 31. . A tongue piece 33 is provided at the center of the base 31 so as to protrude in the same direction of the arrow D as the side portions 32 and 32. Small protrusions 33a and 33a are integrally provided on the front and back of the tongue piece 33. Has been. Stoppers 34, 34 are integrally provided on both sides of the tongue piece 33 of the base 31, and when the display angle of the indicator 14 is maximized as will be described later, the stopper 34 is engaged with the engaging portion of the indicator 14. 24 is engaged. Screw insertion holes 35, 35 are provided in the both side portions 32, 32, and the above-described display mounting concave fitting portion 7 is used for die-cutting at the ends of the both side portions 32, 32 in the arrow D direction. Protrusions 36 and 36 that fit into the holes 10 and 10 are projected. Reference numeral 37 denotes a wall formed in a U shape in plan view, and protrudes so as to be connected to the edges of the base portion 31 and both side portions 32 and 32. As described above, the display 14 displays the display. The wall 37 faces the groove 25 of the indicator 14 when lying on the device mounting concave fitting portion 7.

  Reference numeral 40 denotes a friction locking member which is formed in a flat rectangular tube shape having both ends opened by a hard rubber as a whole. The outer shape of the hollow portion 40a is slightly smaller than the outer shape of the tongue piece 33. . Therefore, by pressing the tongue piece 33 into the hollow portion 40a of the friction locking member 40, the hollow portion 40a is brought into close contact with the tongue piece 33, and the small protrusions 33a and 33a bite into the upper and lower surfaces of the hollow portion 40a. The friction locking member 40 is firmly crowned by the tongue piece 33, and is prevented from falling off. The width l of the friction locking member 40 is formed slightly larger than the interval L1 between the locked surfaces 22a and 22a of the indicator 14, and slightly smaller than the interval L2 between the non-sliding contact surfaces 22b and 22b. It is formed small.

  With this configuration, the display 14 is inverted from the state shown in FIG. 7, and the shaft portion 9 a of the recessed portion 7 for mounting the display is inserted into the recessed portion 16. 14 is mounted on the concave mounting portion 7 for mounting the display. Next, by moving the indicator 14 in the direction of arrow B, that is, in the width direction of the indicator 14, the shaft portion 9a is fitted into the non-through hole 17, so the indicator 14 is shown in FIG. As described above, the shaft portion 9a is pivotally supported around the pivot center, and is placed on the display mounting concave fitting portion 7 so as to be raised and lowered. At this time, the locked portion 18 projects from the opening 8 of the display device mounting recessed portion 7 to the back surface side of the display device mounting recessed portion 7.

  After this state, both the side portions 32 of the bracket 30 are brought into contact with the back surface of the display device mounting recessed portion 7, and the screw inserted through the screw insertion hole 35 is connected to the back surface of the display device mounting recessed portion 7. The bracket 30 is attached to the back surface of the concave mounting portion 7 for mounting the display device by screwing into a screw portion (not shown) provided on the display unit. By attaching the bracket 30, the holes 10 and 10 of the display unit mounting recessed portion 7 are closed by the convex portions 36 and 36 of the bracket 30. Thus, since the holes 10 and 10 are closed by the convex portions 36 and 36 of the bracket 30, dust and the like can be prevented from entering the lower case 2 from the holes 10 and 10. The short circuit of the electronic circuit in 2 etc. can be prevented. Moreover, since it can prevent that dust adheres to the to-be-latched surface 22a of the to-be-latched part 18 and the friction locking member 40, it does not interfere with the rotation operation | movement of the indicator 14. FIG.

  Further, as shown in FIG. 3, the base portion 31 and both side portions 32, 32 of the bracket 30 close the gap between the peripheral end of the opening 8 of the display unit mounting recessed portion 7 and the locked portion 18. A wall 37 projects upward from the opening 8. Further, since the inner side surfaces of the both side portions 32 and 32 of the bracket 30 are in contact with the outside of the locked portion 18 of the display device 14 and the locked portion 18 is sandwiched between the both side portions 32 and 32, Movement in the width direction (arrow A direction) is restricted. Therefore, since the shaft portion 9a is not detached from the non-through hole 17 of the display device 14, the display device 14 is attached to the display device mounting recessed fitting portion 7 so as to be rotatable.

  The both sides of the friction locking member 40 come into contact with the locked surfaces 22a and 22a of the display device 14 attached in this manner with a predetermined pressing force. For this reason, when the display 14 is rotated about the shaft portion 9a, the friction locking member 40 comes into sliding contact with the locked surfaces 22a and 22a. ), The display device 14 can be raised from the display device mounting recessed fitting portion 7 and set to a desired display angle.

  From this state, when the display unit 14 is again laid down on the display unit mounting recessed portion 7 and the display angle of the display unit 14 is set to 0 °, as shown in FIG. Both side portions of 40 face the non-sliding contact surfaces 22b and 22b of the display unit 14. As described above, since the distance L2 between the non-sliding contact surfaces 22b and 22b is formed larger than the width l of the friction locking member 40, both sides of the friction locking member 40 and the non-sliding contact surfaces 22b and 22b The pressure contact is released. Accordingly, since the elastic deformation of the friction locking member 40 due to the pressing of the locked surface 22a is released, the elastic locking force is not generated in the direction in which the collapsed display 14 is raised on the friction locking member 40. Thus, the display 14 can be easily in a lying state.

  Further, when the frictional locking member 40 moves from the locked surface 22a to the non-sliding contact surface 22b, as shown in FIG. 9, the frictional locking member 40 is in pressure contact with the stepped portion 23a and the rib 23b. Get over the part 23a and the rib 23b. For this reason, the operator who rotates the display device 14 can confirm that the display device 14 has fallen down on the display device mounting recessed fitting portion 7 and the display angle is set to 0 °. Therefore, the display angle can be surely set to 0 °. At this time, since the stepped portion 23a and the rib 23b are engaged with the end face of the friction locking member 40, the display angle of the indicator 14 can be reliably maintained at 0 ° by this engagement. . Further, when the display 14 is raised from a display angle of 0 °, the friction locking member 40 gets over the step 23a and the rib 23b while being pressed by the step 23a and the rib 23b. Usability is improved because it can be confirmed that the user has started getting up.

  In the state where the display angle of the display device 14 is 0 °, as described above, the base portion 31 and the both side portions 32, 32 of the bracket 30 are connected to the peripheral end of the opening 8 of the recessed portion 7 for mounting the display device. The space between the locking portion 18 is closed. At the same time, the wall 37 surrounding the opening 8 of the recessed portion 7 for mounting the display device faces the groove 25 of the display device 14 as shown in FIG. Intrusion into the enclosure can be restricted. In addition, since the convex portion 26 of the display unit 14 is engaged with the convex portion 11 of the concave mounting portion 7 for mounting the display unit with the display angle of the display unit 14 being 0 °, The surface of the recessed portion 7 for placing the display device does not come into contact. Therefore, since it can prevent that the surface of the display device mounting part 7 is damaged, when the display device 14 is raised, the aesthetic appearance of the device housing is not impaired.

  In the present embodiment, the friction locking member 40 is slidably contacted with the locked surface 22a, but may be slidably contacted with the small diameter portion 21.
