Summary of the Invention

Problems to be Solved by the Invention

[0004] In recent years, in the "Responsibility to Create, Responsibility to Use" of the SDGs, the right of users of devices to repair products without going through manufacturers has been advocated, and an improvement in reworkability has been demanded. However, in the configuration of Patent Document 1, when the tackiness is large, it is not known on which side of the first member and the second member the gasket will peel off when disassembling the first member and the second member. If it does not peel off on the desired side, it is difficult to reassemble and the reworkability is impaired. Therefore, it is difficult to apply the configuration of Patent Document 1 to a part with a high rework frequency.

[0005] An object of the present invention is to provide an electronic device capable of improving reworkability.

Means for Solving the Problems

[0006] An electronic device according to one aspect of the present invention includes an elastic member, a compression member that compresses the elastic member, and a mounting member including a groove in which the elastic member is disposed and an overlapping portion that overlaps a part of the groove when viewed in the compression direction of the compression member. A part of the elastic member seals between the mounting member and the compression member in a state compressed by the compression member, and another part of the elastic member is disposed between the groove and the overlapping portion.

Advantages of the Invention

[0007] According to the present invention, it is possible to provide an electronic device capable of improving reworkability.

Embodiments for Carrying Out the Invention

[0009] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. In each figure, the same members are denoted by the same reference numerals, and redundant descriptions are omitted.

[0010] FIG. 1 is an external view of a digital single-lens reflex camera 1 (hereinafter referred to as camera 1), which is an example of an electronic device according to an embodiment of the present invention. FIG. 1(a) is a perspective view of camera 1 seen from the back side. FIG. 1(b) is a perspective view of camera 1 seen from the front side. FIG. 1(c) is a rear view of camera 1. The viewfinder 2 is used to observe a subject image formed through a lens barrel (not shown) and determine the composition at the time of shooting. The display device 3 is used to confirm a captured image or the like. The grip portion 4 is gripped by the user at the time of shooting or the like. The release button 5 is pressed when shooting. Camera 1 detects the depression of the release button 5, controls the driving of an imaging element (not shown), the operation of an image processing circuit, and the compression process of a recording processing circuit, etc., and records a captured image.

[0011] Hereinafter, the drip-proof structure around the viewfinder 2 will be described. FIG. 2 is a diagram showing an example of the configuration around the viewfinder 2, and is a schematic cross-sectional view taken along line A-A around the viewfinder 2 in FIG. 1(c). The viewfinder cover 21 and the viewfinder panel 22 are mounting members on which a seal member (elastic member) 24 is disposed. The exterior cover (compression member) 23 compresses the seal member 24 in the direction (compression direction) D1 in FIG. 2. By compressing the seal member 24 with the exterior cover 23, sealing can be achieved, and water can be prevented from entering through the gap between the viewfinder cover 21 and the exterior cover 23.

[0012] Further, a groove shape (groove) 41 is formed by the viewfinder cover 21 and the viewfinder panel 22. A locking shape (superimposed portion) 42 that overlaps a part of the groove shape 41 is formed in the mounting member formed by the viewfinder cover 21 and the viewfinder panel 22 when viewed from the direction D1. A part of the seal member 24 is disposed between the groove shape 41 and the locking shape 42. The seal member 24 is a curable elastic member that cures by applying predetermined conditions and is installed in the groove shape 41.

[0013] Figure 3 is a view with the exterior cover 23 removed from Figure 2, showing the state before the seal member 24 is compressed by the exterior cover 23. The seal member 24 includes a locked portion 52 and a tip shape (sealing portion) 45. The locked portion 52 is locked by a locking shape 42. Thereby, it is possible to prevent the seal member 24 from peeling off from the groove shape 41. The tip shape 45 has a shape that is easily compressed and crushed by the exterior cover 23, and contributes to the sealing between the viewfinder cover 21 and the exterior cover 23.

[0014] The seal member 24 is a curable elastic member that is applied in a liquid state to the groove shape 41 and cured by UV irradiation. By applying the seal member 24 in a liquid state, it is possible to more reliably fill the seal member 24 into the locking shape 42. Also, it can be filled into various complex groove shapes without increasing the number of assembly steps. Further, although the seal member 24 is a curable elastic member in this embodiment, the present invention is not limited thereto. The seal member 24 may be another elastic member such as a rubber member, for example.

[0015] Note that, as a method for curing the seal member 24, not only UV irradiation but also other methods such as curing by two-component mixing, thermosetting by heating, curing by reaction with moisture, curing by drying, and solidification by cooling may be used.

[0016] Here, when removing the exterior cover 23, since the seal member 24 is sticky, there is a risk that it will stick to the exterior cover 23 and come off from the groove shape 41. In this embodiment, by providing the locking shape 42, the seal member 24 (locked portion 52) installed in the groove shape 41 can be caught by the locking shape 42, and peeling from the groove shape 41 can be suppressed.

[0017] Here, as shown in Figure 4, if the seal member 24 can be cured after being applied to the groove shape 41, the viewfinder cover 21 and the viewfinder panel 22 may be integrated without being divided.

[0018] As described above, according to the configuration of the present embodiment, it is possible to provide an electronic device having a drip-proof configuration that reduces the peeling of the curable elastic member from the member to be coated and enables improvement in reworkability.

[0019] FIG. 5 is a diagram showing another example of the configuration around the viewfinder 2. The UV light transmitting member 25 is a member to be coated that transmits UV light. By making at least a part of the member to be coated a material that transmits UV light, the range where UV light can be irradiated is widened, so that the curing of the seal member 24 can be promoted and the process time can be shortened. Note that the same effect can be obtained by configuring the viewfinder panel 22 with a material that transmits UV light.

[0020] The viewfinder cover 21 may include a standing wall shape (extension part) 43 that extends toward the exterior cover 23 in the compression direction of the exterior cover 23. Thereby, since the fall of the seal member 24 in the direction D2 caused by the compression by the exterior cover 23 can be suppressed, the seal member 24 can be stably crushed, and the sealing performance can be improved. Therefore, it is possible to further suppress water from entering through the gap between the viewfinder cover 21 and the exterior cover 23. Further, by providing the standing wall shape 43, the adhesion area of the seal member 24 can be increased by the range S2, so that the peeling of the seal member 24 from the groove shape 41 can be further suppressed.

[0021] FIG. 6 is a cross-sectional view taken along line B-B of FIG. 5. FIG. 7 is a cross-sectional view taken along line C-C of FIG. 6. The viewfinder cover 21 and the viewfinder panel 22 may each include a first contact portion 44a and a second contact portion 44b that are parallel to the direction D1 of FIG. 2 in order to regulate their mutual positions in the direction D3 of FIG. 5. Thereby, the groove shape 41 can be stably configured. Note that being parallel to the direction D1 of FIG. 2 includes not only the case of being strictly parallel but also the case of being substantially parallel (substantially parallel).

[0022] Also, in the direction D1 of FIG. 2, it is desirable that the upper end Z2 of the seal member 24 (the position where it contacts the exterior cover 23) is located on the side of the exterior cover 23 with respect to the upper end Z1 of the first contact portion 44a and the second contact portion 44b (the position of the region where the two contact portions contact each other). Thereby, in the range S4 shown in FIG. 7, between the upper end Z1 of the first contact portion 44a and the second contact portion 44b and the exterior cover 23, the installation of the seal member 24 is not interrupted. Therefore, the seal member 24 can be continuously configured between the viewfinder cover 21 and the exterior cover 23, and it is possible to further suppress water from entering through the gap between the viewfinder cover 21 and the exterior cover 23.

[0023] Also, with respect to the range S1 in FIG. 5 where the seal member 24 contacts the viewfinder cover 21 or the viewfinder panel 22, hydrophilicity may be imparted by performing hydrophilic processing such as a fine shape or painting. Thereby, the adhesive force of the seal member 24 can be increased.

[0024] Also, with respect to the range S3 in FIG. 5 where the seal member 24 can contact the exterior cover 23, water repellency may be imparted by performing water repellent processing such as a fine shape or painting. Thereby, the adhesive force of the seal member 24 to the exterior cover 23 can be reduced.

[0025] By imparting hydrophilicity and water repellency, it is possible to further suppress the seal member 24 from peeling off from the viewfinder cover 21.

[0026] The manufacturing process of the components around the viewfinder 2 will be described below. Fig. 8 is a schematic diagram showing the manufacturing process of the components around the viewfinder 2. First, as shown in Figs. 8(a) and 8(b), the viewfinder panel 22 is aligned and placed with respect to the viewfinder cover 21. Thereby, the groove shape 41 and the locking shape 42 are formed. Next, as shown in Fig. 8(c), a seal member 24 is applied to the groove shape 41 formed in Fig. 8(b). Next, as shown in Fig. 8(d), the seal member 24 is irradiated with UV light to cure the seal member 24 and bond it to the groove shape 41. Thereby, the seal member 24 is locked by the locking shape 42, and the tip shape 45 is formed. Finally, as shown in Fig. 8(e), the tip shape 45 is compressed in the direction D1 by the exterior cover 23. Thereby, after the groove shape 41 and the locking shape 42 are formed by a plurality of components, by applying the seal member 24, the coating process can be simplified and the sealing performance by the seal member 24 can be improved.
