In addition, a door panel 12 is attached to the opening 17, and when the switch or the slot is not used, the door 17 covers the opening 17 so that the inside of the opening 17 cannot be seen from the outside. .

  The door panel attachment structure according to this embodiment is applied when the door panel 12 is attached to the opening 17. Hereinafter, a door panel attachment structure for attaching the door panel 12 to the opening 17 will be described.

  A rectangular hole 20 is formed at both upper side positions of the opening 17. As shown in FIG. 3A, the hole portion 20 forms a vertical wall end portion 23 which is a lower end portion (Z2 direction end portion) of the vertical wall portion 22 constituting the front panel 13 and an opening portion 17. It is formed between the horizontal wall portion 24 and the horizontal wall end portion 25 which is the end portion in the arrow Y2 direction in the figure.

  The hole 20 is configured to open in a direction different from the direction in which the door panel 12 is inserted into the opening 17 (arrow Y1 direction in the figure) when the door panel 12 is mounted in the opening 17. Specifically, in this embodiment, the hole 20 is configured to open in the direction of the arrow Z1 in the figure, which is orthogonal to the insertion direction (Y1 direction) of the door panel 12. In addition, a guide portion 26 having a substantially quarter circle shape is formed at a lower position of the hole portion 20. The guide portion 26 is not necessarily provided.

  On the other hand, a first locking claw portion 21 is formed at the lower center position of the opening 17. The first locking claw portion 21 extends in the direction of the arrow Y2, and the second locking claw portion formed on the door panel 12 in a state where the door panel 12 is attached to the opening 17 as will be described later. 37 is engaged.

  Next, the door panel 12 attached to the opening 17 having the above-described configuration will be described with reference to FIG. 2 in addition to FIGS. The door panel 12 is resin-molded and has a configuration in which attachment portions 33 are provided on both side portions of the upper edge portion 31 of the panel body 30.

  As shown in FIGS. 2D, 2E, and 3A, the panel main body 30 has a shape that is bent in a substantially letter shape in a side view. A second locking claw portion 37 and a finger hook portion 38 are formed at the center position of the lower edge portion 32 of the panel body 30.

The second locking claw portion 37 is formed to extend in the arrow Y2 direction in the figure. The second locking pawls 37 are those door panel 12 attached to the open mouth portion 17 exhibits the function of performing lock to prevent withdrawal. In addition, the finger hanging portion 38 is provided to easily remove the door panel 12 attached to the opening portion 17 by hooking a finger when the door panel 12 is removed from the device main body 11.

  Next, the attachment part 33 will be described. The mounting portion 33 includes a corner portion 34 (corresponding to a first engaging portion described in claims) and an engaging claw portion 35 (corresponding to a second engaging portion described in claims). It has been configured. The attachment portion 33 can be formed collectively at the time of resin molding of the door panel 12 and can be easily formed.

  The corner portion 34 is formed as a part of the upper edge portion 31 and has a substantially right-angle shape in a side view. Further, the engaging claw portion 35 is formed to extend upward from a position slightly deviated inward (right side in FIG. 2E) from the formation position of the corner portion 34. Here, the extending direction of the engaging claw portion 35 is configured to coincide with the same direction (arrow Y1 direction) as the direction in which the door panel 12 is inserted into the opening portion 17.

  That is, as will be described later, when the door panel 12 is mounted on the device main body 11, the door panel 12 is first inserted into the opening 17, but the extending direction of the engaging claw 35 is such that the door panel 12 is moved to the opening 17. It is set to be the same direction as the insertion direction.

  Further, as will be described later, the engaging claw portion 35 enters the hole portion 20 formed in the opening portion 17 and engages with the device main body 11. In order to easily enter the hole portion 20, the tip portion of the attachment portion 33 has a curved shape (a shape having an R). A curved portion 36 is formed on the side of the engaging claw portion 35. The curved portion 36 has a shape corresponding to the guide portion 26 formed in the opening 17 described above.

  Next, a specific operation for attaching the door panel 12 to the device main body 11 in the door panel attachment structure having the above configuration will be described mainly with reference to FIG.

  In order to attach the door panel 12 to the device main body 11, first, the door panel 12 is positioned with respect to the device main body 11. At this time, as shown in FIG. 3A, positioning is performed so that the attachment portion 33 of the door panel 12 and the formation position of the hole portion 20 of the opening portion 17 are substantially opposed to each other.

  Subsequently, the door panel 12 is moved in the horizontal direction (in the direction of arrow Y <b> 1 in the drawing) toward the device main body 11, and the attachment portion 33 is inserted into the opening portion 17. At this time, the extending direction of the engaging claw portion 35 and the inserting direction for inserting the door panel 12 into the device main body 11 (opening portion 17) are made to coincide with each other.

  When the corner portion 34 constituting the attachment portion 33 is inserted to a position where it faces the vertical wall end portion 23 of the vertical wall portion 22, the door panel 12 is moved counterclockwise as shown in FIG. Rotate. At this time, the corner portion 34 engages with the vertical wall end portion 23, and the door panel 12 rotates about the engagement position between the corner portion 34 and the vertical wall end portion 23 as the rotation center.

  In this embodiment, the guide portion 26 is formed in the opening portion 17, and the curved portion 36 having a shape corresponding to the guide portion 26 is formed in the attachment portion 33. For this reason, when the bending portion 36 slides in the guide portion 26, the door panel 12 is rotated by being guided by the guide portion 26. Thereby, rotation of the door panel 12 can be performed stably.

  As described above, when the door panel 12 rotates with respect to the device main body 11, the engaging claw portion 35 constituting the attachment portion 33 enters the hole portion 20. As described above, the hole 20 opens upward (in the direction of the arrow Z1). In other words, the hole 20 is configured to be opened in a direction orthogonal to the direction (Y1 direction) in which the door panel 12 is inserted into the opening 17.

  Therefore, the engagement claw portion 35 does not enter the hole portion 20 simply by inserting the door panel 12 into the opening portion 17. However, the engaging claw portion 35 engages with the device main body 11 by rotating the door panel 12. Specifically, by rotating the door panel 12, the engaging claw portion 35 engages with the vertical wall end portion 23 and the horizontal wall end portion 25.

  Further, when the door panel 12 is rotated, as shown in FIG. 3C, the extending direction of the engaging claw portion 35 coincides with the opening direction of the hole portion 20 and the second formed on the door panel 12. The locking claw portion 37 engages with the first locking claw portion 21 provided in the opening portion 17. In this engaged state, the engaging claw portion 35 has completely entered the hole portion 20 and is engaged with the device main body 11. Further, the upper edge portion 31 of the panel body 30 is in a state of facing the vertical wall end portion 23 of the vertical wall portion 22.

  Thus, in a state where the door panel 12 is attached to the device main body 11, the door panel 12 is engaged with the device main body 11 by the attachment portions 33 on both sides of the upper edge portion 31 of the panel main body 30, and the lower edge portion of the panel main body 30. The central portion of 32 is engaged (locked) with the device body 11 by the first and second locking claws 21 and 37.

  Thus, since both the upper edge part 31 and the lower edge part 32 of the door panel 12 are engaged with the apparatus main body 11, the door panel 12 can be reliably attached to the apparatus main body 11 (opening part 17), and it is easy. There is no such thing as leaving. Therefore, the door panel 12 can be attached to the device main body 11 with high reliability while having a simple configuration in which the hole portion 20 is formed in the opening portion 17 and the attachment portion 33 is formed in the door panel 12.

In the present embodiment, the center portion of the lower edge portion 32 of the panel main body 30 is engaged with the device main body 11 by the second locking claw 37 in a state where the door panel 12 is mounted on the device main body 11. Since the panel main body 30 has a shape that is long in the left-right direction (X1, X2 direction ) , warping is likely to occur at the center portion during mounting. However, since the second locking claw 37 is provided at a position where the warpage is likely to occur and the second locking claw 37 is engaged with the first locking claw 21, The rigidity in the central portion can be increased, and the warpage of the door panel 12 can be prevented.

  By the way, as shown in FIG.3 (C), when the door panel 12 is mounted | worn with the apparatus main body 11, the case where the strong external force F as shown by the arrow F in the figure is applied is assumed. Here, the “strong external force” refers to an unexpected force or the like by the user, and is larger than a normal force that the operator applies to the door panel 12 using the finger hook portion 38 when the door panel 12 is removed from the device main body 11. It means power.

  In the door panel mounting structure according to the present embodiment, the engagement claw 35 is engaged with the hole 20 of the device main body 11 at the upper edge 31 of the door panel 12 as described above, and at the lower edge 32. The door panel 12 is attached to the device main body 11 by the engagement of the first locking claw portion 21 and the second locking claw portion 37.

  In such engagement using the claw portions 35, 21, and 37, when a strong external force is applied, the engagement is released by elastic deformation of the claw portions 35, 21, and 37. That is, in the door panel mounting structure according to the present embodiment, when a strong external force is applied to the door panel 12, all or part of the engagement by the claw portions 35, 21, and 37 is released. Leave.

  At the time of detachment, the claw portions 35, 21, and 37 are elastically deformed. However, when the door panel 12 is detached from the device main body 11 (by applying external force), the original state is restored. For this reason, when the door panel 12 is detached from the device main body 11, the claw portions 35, 21, 37 or the hole portion 20 are not damaged.

  The panel body 30 has a shape that is bent into a substantially square shape, and is easily deformed elastically when an external force is applied. Therefore, also by this, when external force is applied, the engagement of the claw portions 35, 21, and 37 can be smoothly released. This also suppresses the occurrence of damage to the claw portions 35, 21, 37 and the opening 20 when an external force is applied.

  In the present embodiment, even if an unexpected external force is applied to the door panel 12 as described above, the device main body 11 or the door panel 12 can be reliably prevented from being damaged. Therefore, according to the door panel mounting structure according to the present embodiment, the mounting reliability of the door panel 12 to the device body 11 can be increased. Moreover, since the door panel mounting structure according to the present invention is simple as described above, the cost can be reduced.
