Description

  The present invention relates to a remote control, and in particular, prevents the occurrence of a situation in which foreign matter such as dust or dirt (hereinafter abbreviated as “dust”) adheres to a display unit configured by an LCD or the like housed inside the remote control. Related to technology.

Inside the remote control, a display unit usually composed of an LCD or the like is accommodated. If dust or the like that has entered from the outside adheres to the surface of such a display unit, the appearance may deteriorate and the appearance may be impaired, so conventionally, a dust-proof measure for the display unit has been proposed. In particular, when attaching to a wall surface, dust or the like may be filled in the air due to drilling work or the like on the wall surface.
In Patent Document 1 (see FIGS. 1 and 2 of the same document), in an electronic device in which a display unit is covered with a casing in which a transparent screen is fitted as a display window, a guide wall surrounding the display unit protrudes from the casing side. It has been proposed that a window frame-shaped elastic member be interposed so as to fill the gap between the guide wall and the display unit. In the display device of Patent Document 2 (see FIG. 5 of the same document), the front end surface of the frame for installing the display unit on the substrate is placed against the back surface of the housing in which the transparent screen is fitted via the seal packing. It has been proposed to make contact. Further, in the remote control device of Patent Document 3 (see FIG. 5 of the same document), the ribs protrude oppositely from both the case side where the display unit is provided and the cover side which covers the front surface of the case. It has been proposed to cover the ribs from above so as to overlap in the inner and outer directions.

By the way, as a dust-proof measure for the display unit built in the remote control, when the enclosed space is partitioned by surrounding the display unit, even if the partition wall protrudes on the side of the substrate on which the display unit is installed, Alternatively, even if the partition wall protrudes from the cover that covers the substrate on which the display unit is installed, the side on which the display unit is installed (for example, the substrate side) is larger than the size of the display unit. There is a need. For example, as shown in the examination plan of FIG. 9, the partition wall 102 surrounding the periphery of the display unit 101 installed on the substrate 100 is protruded from the cover 103, and the front end surface of the partition wall 102 is brought into contact with the substrate 100. In order to accommodate the display unit 101 in the sealed space 104, it is assumed that the target substrate 100 with which the front end surface of the partition wall 102 abuts is larger than the display unit 101 and spreads around.
On the other hand, it is considered to reduce the size of the substrate for cost reduction and compactness of the remote control, and it is assumed that a part of the display part protrudes outside the edge of the substrate, If it becomes so, formation of the sealed space by the said partition wall will become impossible. In other words, if it is attempted to reduce the size of the remote controller or reduce the cost by reducing the size of the substrate, it may cause a situation in which it is impossible to take the above dust-proof measures.

  The present invention has been made in view of such circumstances, and an object of the present invention is to provide a sealed space even if a part of the display portion protrudes from the substrate for miniaturization of the remote controller. An object of the present invention is to provide a remote control capable of appropriately realizing a dust-proof measure by formation.

That is, the substrate includes a display unit disposed at a position facing the display window unit of the front case and a part of the substrate projecting from the edge of the substrate. Then, the front case and the rear case are provided with ribs that protrude on opposite sides. The ribs of the front case are formed so as to surround the periphery of the display unit, while the ribs of the rear case are formed so as to surround the protruding part of the display unit protruding from the substrate, and the front case The rib is brought into contact with both the substrate around the display unit and the rib of the rear case, so that a sealed space for accommodating the display unit is defined. 1).

  In the case of the present invention, the ribs of the front case surround the entire periphery of the display unit including the protruding part, while the ribs of the rear case surround the protruding part of the display unit, and the ribs of the front case are Therefore, a sealed space for accommodating the display portion is formed in the compartment. Since the display unit is housed in a sealed space, even if it is placed in an environment in which dust or the like is likely to enter from the outside through the gaps or openings in the front and rear cases, The dust and the like are prevented from entering, and the dust and the like are reliably prevented from adhering to the display portion. Of course, intrusion of water droplets in addition to dust is also prevented.

  In the remote controller of the present invention, a step portion is provided on the front end surface of the rib of the rear case, and the front end surface on one side is in contact with the rear surface of the substrate across the step portion, while the front end surface on the other side is the front surface. It can be set as the structure contact | abutted with the rib of a case (Claim 2). By doing so, it becomes possible to make the tip surface of the rib on the other side across the stepped portion and the front surface of the substrate flush with each other. When the ribs of the case are brought into contact with each other, the sealed space is reliably partitioned. Conversely, a step portion can be provided on the front end surface of the rib of the front case.

  Furthermore, in the remote controller of the present invention, the rib of the rear case can be formed in an annular shape so as to surround the protruding portion. By doing so, it is possible to surround the protruding portion in a ring shape in a minimum range, and to increase the sealing effect (dust-proof effect) by making the sealed space as small as possible. It becomes possible.

  As described above, according to the remote controller of the present invention, the ribs of the front case surround the entire periphery of the display unit including the protruding part, while the ribs of the rear case surround the protruding part of the display unit, Since the ribs of the front case are brought into contact with both the substrate around the display unit and the ribs of the rear case, a sealed space for accommodating the display unit can be partitioned. become. Since the display unit can be stored in a sealed space, even if the remote control is placed in an environment where dust or the like easily enters from the outside through the gaps or openings in the front and rear cases, It is possible to prevent the dust and the like from entering the display, and reliably prevent the dust and the like from adhering to the display portion.

  According to the remote control of claim 2, the front end surface of the rib of the rear case is provided with a stepped portion, and the front end surface on one side is brought into contact with the rear surface of the substrate across the stepped portion, while the front end surface on the other side Is configured to abut against the ribs of the front case, so that the tip surface of the rib on the other side and the front surface of the substrate can be flush with each other with the stepped portion interposed therebetween. By bringing the rib of the front case into contact with the contact surface, the sealed space can be surely defined.

  Further, according to the remote control of claim 3, by forming the ribs of the rear case in an annular shape so as to surround the protruding portion, the protruding portion can be easily surrounded in an annular shape within a minimum range, and sealed. By making the space as small as possible, the sealing effect (dustproof effect) can be further enhanced.

The amount of protrusion is such that the lower rib 13 protrudes to the same level position as the lower support surface 112 of each support portion 11 and the upper rib 12 protrudes to the same level position as the upper support surface 113 of each support portion 11. Is set. Accordingly, the lower rib 13 contacts the rear surface of the substrate 6 together with the lower support surface 112 to support the substrate 6, while the upper rib 12 extends flush with the front surface of the substrate 6 together with the upper support surface 113. It can come into contact with the rib 243 of the cover body 2. The upper rib 12 is also provided with convex ribs 121,... That partially cut off or extend upward corresponding to the rib 243 of the cover body 2, and cooperates with the peripheral wall 20 of the cover body 2 to display the display portion. 7 can be sealed.

  With the above configuration, even when the display unit 7 is installed on the substrate 6 with a part of the display unit 7 protruding upward, the display unit 7 is assembled while being sandwiched between the case main body 1 and the cover main body 2. As shown in FIG. 8, the display unit 7 is accommodated in the sealed space S. That is, the rear surface of the upper edge of the substrate 6 is held in contact with the front end surface of the rib 13 of the case body 1 and the lower support surfaces 112 (see FIGS. 5 to 7) of the left and right support portions 11 and 11. The In this state, the display unit 7 is partitioned by the ribs 241 and 241 (see FIG. 7) of the cover body 2 in contact with the front surface of the substrate 6 and the upper support surface 113 of each support unit 11 at the left and right positions. 8, the rib 242 of the cover main body 2 (see FIG. 8) is partitioned in contact with the front surface (the upper surface in FIG. 8) of the substrate 6, and the rib 243 of the cover main body 2 and the rib 12 of the case main body 1 are the front end surface at the upper position. The display unit 7 is accommodated in the sealed space S as described above. Thereby, even if it is placed in an environment where dust or the like easily enters from the outside through the gap or opening of the case main body 1 or the cover main body 2, the dust or the like is prevented from entering the sealed space S. Thus, it is possible to reliably prevent dust and the like from adhering to the display unit 7.

<Other embodiments>
In addition, this invention is not limited to the said embodiment, Other various embodiment is included. That is, in the above-described embodiment, the step portion 111 is provided on the upper support portion 11 so that the front surface of the substrate 6 and the upper support surface 113 are flush with each other. Instead, a step portion having a step amount corresponding to the thickness of the substrate 6 may be provided on the front end surface of the rib on the cover main body 2 side (rib 241 in the embodiment).
Further, on the case body 1 side, the upper rib 12, the left and right support portions 11, 11 and the lower rib 13 are formed so as to surround the protruding portion 71 in an annular shape to a minimum extent and sealed. The space S has a minimum volume as much as possible. However, the present invention is not limited to this, and the lower rib 13 is not essential and may be omitted. In other words, instead of the lower rib 13, it is only necessary to appropriately support the rear surface (back surface) of the substrate 6, and a shielding wall for partitioning the sealed space S may be separately formed.
