Detailed Description
Next, an embodiment in which the present invention is applied to a wristwatch case will be described with reference to fig. 1 to 4.
As shown in fig. 1 and 2, the wristwatch case 1 includes a case body 1. The housing body 1 is formed of hard synthetic resin in a substantially annular shape. Switch mounting holes 2 for mounting a switch device (not shown) are provided on the 2-point side, the 3-point side, the 4-point side, and the 8-point side of the case main body, respectively.
As shown in fig. 1 and 2, the pair of belt mounting portions 3 are positioned by the positioning portions 4 on the side portions of the case body 1 on the 12-point side and the 6-point side, respectively. The pair of band attaching portions 3 are each attached with a wrist band (not shown), and are integrally formed of metal such as stainless steel, and include a case attaching piece 5 disposed on a side surface of the case body 1 and a band connecting piece 6 for connecting the wrist band.
As shown in fig. 1 and 2, the case attachment piece 5 has an inner surface facing the side surface of the case body 1 formed in an arc shape having substantially the same curvature as the side surface of the case body 1, an outer surface formed in a horizontally long rectangular shape, and screw fixing portions 7 formed on both side portions. The belt coupling piece 6 projects outward from the housing body 1 from the middle portion of the outer surface of the housing attachment piece 5, and a belt attachment hole 6a is provided in the projecting portion so as to pass through the housing body 1 in the circumferential direction.
As shown in fig. 2 and 3, the positioning portion 4 includes a protrusion 8 provided on each side portion of the case main body 1 on the 12-point side and the 6-point side, and an engaging recess 9 provided on the arc-shaped inner surface of each case mounting piece 5 of the pair of belt mounting portions 3 facing the protrusion 8 and into which the protrusion 8 is fitted. Thus, the positioning portion 4 positions the tape mounting portion 3 at the side portion of the case body 1 by inserting the engaging recess 9 provided at the inner side portion of the case mounting piece 5 from above into the protrusion 8 provided at the side portion of the case body 1 and fitting the same.
That is, as shown in fig. 2 and 3, when the engagement recess 9 of the case mounting piece 5 is fitted to the protrusion 8 of the case main body 1, the positioning portion 4 regulates the vertical position of the tape mounting portion 3 with respect to the side portion of the case main body 1 and regulates the circumferential position of the tape mounting portion 3 in the side portion of the case main body 1. Thereby, the pair of belt mounting portions 3 are positioned at each of the 12-point side and the 6-point side of the case main body 1 by the positioning portions 4.
In this case, as shown in fig. 2 and 3, a first cushioning member 10 is provided between the case body 1 and the belt mounting portion 3. The first cushioning member 10 is formed in a sheet shape by a synthetic resin having elasticity such as urethane resin or silicone resin. The first buffer member 10 is disposed between the side portion of the case body 1 located above the protrusion 8 of the case body 1 and above the engaging recess 9 of the belt attachment portion 3 and the inner surface of the case attachment piece 5, and buffers an impact when the belt attachment portion 3 receives the impact from the outer circumferential direction of the case body 1.
On the other hand, as shown in fig. 1 to 4, an exterior member 11 is provided on the outer periphery of the upper portion of the case body 1 via a second cushioning member 12. The second cushioning member 12 is formed substantially in a ring shape from a synthetic resin having elasticity such as urethane resin or silicone resin, and is disposed between the upper end surface of the case body 1 and the exterior member 11 via the second cushioning member 12, so that when an impact is applied to the exterior member 11 from above, the impact is cushioned.
As shown in fig. 1 and 2, the second buffer member 12 is integrally provided with a plurality of protective ring portions 12a and a plurality of protective protrusions 12b, the plurality of protective ring portions 12a surrounding the outer peripheries of the plurality of switch attachment holes 2 provided in the housing body 1, and the plurality of protective protrusions 12b being disposed on respective side portions of the plurality of protective ring portions 12a and protecting the switch device (not shown).
As shown in fig. 1 to 4, the exterior member 11 is formed in a substantially annular shape using a metal such as stainless steel. That is, the exterior member 11 is disposed on the upper end surface of the case body 1 via the second buffer member 12, and is disposed so as to cover the outer periphery of the upper portion of the case body 1.
As shown in fig. 1 and 2, the exterior member 11 is provided with mounting cover portions 13 disposed so as to cover upper portions of the screw fixing portions 7 located on both sides of the case mounting pieces 5 of the pair of tape mounting portions 3. The exterior member 11 is provided with a plurality of protective cover portions 11a which are respectively disposed on the plurality of protective protrusions 12b of the second shock-absorbing member 12 and cover the upper portions of the plurality of protective protrusions 12 b.
In this case, as shown in fig. 2 to 4, the decorative member 15 is disposed between the mounting cover portion 13 of the exterior member 11 and the case mounting piece 5 of the belt mounting portion 3. The decorative member 15 is made of a hard synthetic resin having high rigidity, such as Polyoxymethylene (POM), Polyamide (PA), or Polycarbonate (PC). The decorative member 15 is disposed so as to protrude toward the case main body 1 side between the screw fixing portions 7 disposed on both sides of the case mounting piece 5 and the mounting cover portion 13 of the exterior member 11.
Thus, as shown in fig. 2 to 4, the second buffer member 12 is disposed between the inner end portion of the decorative member 15 protruding toward the case main body 1 and the mounting cover portion 13 of the exterior member 11. Further, when the decorative member 15 is disposed between the screw fixing portion 7 on both sides of the case mounting piece 5 and the mounting cover portion 13 of the exterior member 11, both end portions of the decorative member 15 passing through the outer peripheral direction of the case main body 1 are exposed to the outside from between the screw fixing portion 7 and the mounting cover portion 13, which is an important design point.
As shown in fig. 2 and 4, the exterior member 11 and the decorative member 15 are attached to the screw fixing portions 7 on both sides of the case attachment piece 5 by the first screw members 16. That is, screw holes 7a are provided in the screw fixing portions 7 on both sides of the case attachment piece 5 so as to penetrate vertically. Screw insertion holes 13a, 15a into which the first screw members 16 are inserted are provided in the mounting cover portion 13 and the decorative member 15 of the exterior member 11 coaxially with the screw holes 7a of the screw fixing portions 7.
In this case, as shown in fig. 2 and 4, the first screw member 16 is a stepped screw. The first screw member 16 includes a screw portion 16a screwed into the screw hole 7a of the screw fixing portion 7, a head portion 16b inserted into the screw insertion holes 13a and 15a of the mounting cover portion 13 and the decorative member 15 provided in the exterior member 11 and abutting on the upper surface of the screw fixing portion 7, and a head portion 16c having an outer diameter larger than the inner diameter of the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11.
As a result, as shown in fig. 2 and 4, the first screw member 16 is inserted into the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11 and the screw insertion hole 15a of the decorative member 15 from above and screwed into the screw hole 7a of the screw fixing portion 7 in a state where the exterior member 11 is mounted to the upper outer periphery of the case main body 1 via the second cushion member 12, and is fastened, whereby the exterior member 11 is mounted to the case mounting piece 5 of the band mounting portion 3.
In this case, as shown in fig. 2 and 4, when the screw portion 16a of the first screw member 16 is screwed into the screw hole 7a of the screw fixing portion 7 and fastened, the head lower portion 16b of the first screw member 16 is inserted into the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11 and the screw insertion hole 15a of the decorative member 15 and pressed against the upper surface of the screw fixing portion 7.
As shown in fig. 2 and 4, when the head portion 16b of the first screw member 16 is pressed against the upper surface of the screw fixing portion 7, the mounting cover portion 13 of the exterior member 11 is pressed against the screw fixing portion 7 by the head portion 16c of the first screw member 16, and the second cushion member 12 and the decorative member 15 are pressed against the upper surface of the screw fixing portion 7 by the exterior member 11, and in this state, the exterior member 11 is mounted on the case mounting piece 5 of the belt mounting portion 3.
On the other hand, as shown in fig. 1 to 4, a rear cover 17 is disposed at the lower part of the casing body 1 via a waterproof packing 17 a. A pair of flange portions 18 are provided on the outer periphery of the rear cover 17, and are respectively disposed on the lower surfaces of the case mounting pieces 5 of the pair of tape mounting portions 3 when the rear cover 17 is disposed on the lower portion of the case main body 1. Each of the pair of flange portions 18 is provided with a screw insertion hole 18a that is coaxially aligned with the screw hole 7a of the screw fixing portion 7 of the case mounting piece 5.
Thus, as shown in fig. 1 to 4, the rear cover 17 is attached to each of the case mounting pieces 5 of the pair of band mounting portions 3 by inserting the second screw members 19 into the respective screw insertion holes 18a of the pair of flange portions 18 in a state where the respective screw insertion holes 18a of the pair of flange portions 18 and the screw holes 7a of the screw fixing portions 7 of the case mounting pieces 5 are coaxially aligned, and by screwing and fastening the screw portions 19a of the second screw members 19 to the screw holes 7a of the screw fixing portions 7 from below.
That is, as shown in fig. 1 to 4, when the second screw member 19 is screwed and fastened to the screw hole 7a of the screw fastening portion 7, the tip of the screw portion 19a of the second screw member 19 approaches the tip of the screw portion 16a of the first screw member 16 with a gap therebetween without coming into contact with the tip. Thereby, the flange 18 is pressed against the lower surface of the case mounting piece 5 of the tape mounting portion 3 by the head 19b of the second screw member 19, and the rear cover 17 is mounted on the case mounting piece 5 of the tape mounting portion 3.
Next, the operation of the watch case will be described.
In assembling the wristwatch case, first, the pair of strap attaching portions 3 are positioned and arranged on each of the 12-point side and the 6-point side of the case body 1 by the positioning portions 4. At this time, the first cushioning member 10 is disposed in advance above the protrusion 8 on the side of the housing body 1. In this state, the engaging recess 9 provided on the inner surface of the case attachment piece 5 of the tape attachment portion 3 is fitted from above to the protrusion 8 provided on the side portion of the case main body 1.
Thus, the first cushioning member 10 is disposed between the upper side of the protruding portion 8 on the side portion of the case body 1 and the upper side of the engagement recess 9 of the case attachment piece 5 of the belt attachment portion 3. In this state, the position of the tape mounting portion 3 in the vertical direction with respect to the side portion of the case main body 1 is regulated by the positioning portion 4, and the position of the tape mounting portion 3 in the circumferential direction of the side portion of the case main body 1 is regulated by the positioning portion 4. Thus, the pair of tape attaching portions 3 are positioned and arranged on each of the 12-point side and the 6-point side of the case main body 1.
In this state, the second cushioning member 12 is disposed at the upper end portion of the case body 1, and the exterior member 11 is disposed on the upper outer periphery of the case body 1. At this time, the decorative member 15 is disposed on the upper surface of the case mounting piece 5 of the belt mounting portion 3 in advance, and in this state, the second cushioning member 12 is disposed on the upper end surface of the case main body 1. Then, the plurality of protective ring portions 12a of the second buffer member 12 are disposed on the outer periphery of the plurality of switch attachment holes 2 of the case body 1, and the plurality of protective protrusions 12b of the second buffer member 12 are disposed on the respective side portions of the plurality of switch attachment holes 2 of the case body 1.
The exterior member 11 is disposed on the upper outer periphery of the case body 1. At this time, the mounting cover portions 13 of the exterior member 11 are made to correspond to the screw fixing portions 7 on both sides of the case mounting piece 5 of the band mounting portion 3, and the protective cover portions 11a of the exterior member 11 are made to correspond to the plurality of protective protrusions 12b of the second buffer member 12. Then, the decorative member 15 is sandwiched between the mounting cover portion 13 of the exterior member 11 and the screw fixing portions 7 on both sides of the case mounting piece 5 of the belt mounting portion 3.
At this time, the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11 and the screw insertion hole 15a of the decorative member 15 are coaxially aligned with the screw hole 7a of the screw fixing portion 7 of the case mounting piece 5. In this state, the exterior member 11 is attached to the screw fixing portion 7 of the case attachment piece 5 by the first screw member 16. At this time, the screw portion 16a of the first screw member 16 is inserted into the screw insertion holes 13a and 15a of the mounting cover portion 13 and the decorative member 15 of the exterior member 11 from above, and screwed into and fastened to the screw hole 7a of the screw fastening portion 7.
At this time, the underhead portion 16b of the first screw member 16 is inserted into the mounting cover portion 13 of the exterior member 11 and the screw insertion holes 13a and 15a of the decorative member 15 to be close to or in contact with the upper surface of the screw fixing portion 7, and when the threaded portion 16a of the first screw member 16 is fastened to the threaded hole 7a of the screw fixing portion 7 in this state, the underhead portion 16b of the first screw member 16 is pressed against the upper surface of the screw fixing portion 7.
Thereby, the head portion 16c of the first screw member 16 presses the mounting cover portion 13 of the exterior member 11 against the screw fixing portion 7. At this time, the underhead portion 16b of the first screw member 16 is pressed against the upper surface of the screw fixing portion 7, and the second buffer member 12 and the decorative member 15 are pressed against the upper surface of the screw fixing portion 7 with a constant pressing force by the mounting cover portion 13 of the exterior member 11, whereby the exterior member 11 is mounted on the case mounting piece 5 of the tape mounting portion 3.
The rear cover 17 is disposed at the lower portion of the case body 1 and attached to the belt attachment portion 3. At this time, the rear cover 17 is disposed at the lower portion of the case body 1, and the pair of flange portions 18 of the rear cover 17 are disposed below the case mounting pieces 5 of the pair of tape mounting portions 3. At this time, the screw insertion holes 18a of the flange portion 18 and the screw holes 7a of the screw fixing portions 7 of the case mounting piece 5 are coaxially aligned.
In this state, the screw portion 19a of the second screw member 19 is inserted into the screw insertion hole 18a of the flange portion 18 from below the rear cover 17, and is screwed into and fastened to the screw hole 7a of the screw fixing portion 7 from below. Then, the pair of flange portions 18 of the rear cover 17 are attached to the respective case attachment pieces 5 of the pair of band attachment portions 3. At this time, the tip of the threaded portion 19a of the second screw member 19 approaches the tip of the threaded portion 16a of the first screw member 16 with a gap therebetween without coming into contact with the tip.
Therefore, even if the screw portion 19a of the second screw member 19 is screwed into the screw hole 7a of the screw fixing portion 7 and fastened, the tip of the screw portion 19a of the second screw member 19 does not abut on the tip of the screw portion 16a of the first screw member 16, and therefore the head portion 19b of the second screw member 19 presses the flange portion 18 against the lower surface of the case mounting piece 5 with the mounting portion 3. Therefore, the rear cover 17 is reliably attached to the case attachment piece 5 of the tape attachment portion 3.
In this case, since the exterior member 11 is attached to the band attachment portion 3 positioned at the side of the case body 1 by the positioning portion 4 by the first screw member 16 and the back cover 17 is attached by the second screw member 19, the case body 1 can be sandwiched between the exterior member 11 and the back cover 17.
Therefore, even if the exterior member 11 and the rear cover 17 receive an impact from the outside, the impact can be received by the belt mounting portion 3, and the impact is not directly applied to the case body 1, so that the impact resistance can be improved, and the case body 1 can be formed compactly, so that the entire case can be downsized.
That is, in this wristwatch case, since the exterior member 11 is attached to the strap attaching portion 3 positioned at the side portion of the case body 1 by the positioning portion 4 by the first screw member 16, when an impact is applied to the exterior member 11 from above, the impact can be received by the strap attaching portion 3. Therefore, the impact applied to the exterior member 11 is not directly applied to the case body 1.
At this time, since the second cushioning member 12 is disposed between the exterior member 11 and the case body, when the exterior member 11 receives an impact from above, the impact can be cushioned by the second cushioning member 12. Therefore, the impact applied to the belt mounting portion 3 can be alleviated, and therefore the impact can be prevented from being directly transmitted to the case main body 1.
In this case, when the screw portion 16a of the first screw member 16 is screwed and fastened to the screw hole 7a of the screw fixing portion 7 on both sides of the case mounting piece 5 of the tape mounting portion 3, the exterior member 11 is mounted to the tape mounting portion 3 in a state where the head lower portion 16b of the first screw member 16 is in contact with the upper surface of the screw fixing portion 7, and therefore, when the exterior member 11 receives an impact from above, the second cushioning member 12 can satisfactorily cushion the impact, and thus, the impact received by the exterior member 11 can be reliably prevented from being transmitted to the tape mounting portion 3.
Further, when the belt connecting piece 6 with the belt attaching portion 3 receives an impact from the outside on the outer peripheral side of the case main body 1, the impact can be buffered by the first buffer member 10 disposed between the case main body 1 and the case attaching piece 5 with the belt attaching portion 3, and therefore, the impact received by the belt connecting piece 6 with the belt attaching portion 3 is not transmitted to the case main body 1.
Further, when the rear cover 17 receives an impact from below, the pair of flange portions 18 of the rear cover 17 are attached to the lower surfaces of the pair of housing attachment pieces 5 of the pair of belt attachment portions 3 by the second screw members 19, so that the impact received by the rear cover 17 can be received by the pair of housing attachment pieces 5 of the belt attachment portions 3, and thus the impact is not directly applied to the housing main body 1.
In this case, since the rear cover 17 is disposed on the lower surface of the case body 1 with the waterproof packing 17a interposed therebetween, when the rear cover 17 receives an impact from the lower side, the impact can be absorbed by the waterproof packing 17a, and thus the impact is not applied to the case body 1.
As described above, according to the timepiece case, shock resistance can be improved by including the case body 1, the strap attaching portion 3 disposed on the side portion of the case body 1, the exterior member 11 attached to the upper outer periphery of the case body 1, the positioning portion 4 for positioning the strap attaching portion 3 on the side portion of the case body 1, and the screw fixing portion 7 which is provided on both sides of the positioning portion 4 and on the strap attaching portion 3 and to which the exterior member 11 is attached by the first screw member 16.
That is, in this wristwatch case, since the exterior member 11 is attached to the strap attaching portion 3 positioned at the side portion of the case body 1 by the positioning portion 4 by the first screw member 16, when an impact is applied to the exterior member 11 from above, the impact can be received by the strap attaching portion 3. Therefore, since the impact applied to the exterior member 11 is not directly applied to the case body 1, the impact resistance can be improved.
In this case, the positioning portion 4 includes the protrusion 8 provided on the side portion of the case main body 1, the engaging recess 9 provided on the belt mounting portion 3 and into which the protrusion 8 is fitted, and the engaging recess 9 of the belt mounting portion 3 is fitted into the protrusion 8 of the case main body 1, whereby the belt mounting portion 3 can be reliably positioned on the side portion of the case main body 1.
That is, when the engaging recess 9 of the case mounting piece 5 is fitted to the protrusion 8 of the case main body 1, the positioning portion 4 can regulate the position of the tape mounting portion 3 in the vertical direction with respect to the side portion of the case main body 1 and also regulate the position of the tape mounting portion 3 in the circumferential direction of the side portion of the case main body 1. This enables the tape mounting portion 3 to be reliably and satisfactorily positioned on the side portion of the case main body 1 by the positioning portion 4.
In addition, in this wristwatch case, since the first cushioning member 10 is provided between the case body 1 and the belt attachment portion 3, when the belt attachment portion 3 receives an impact from the outside on the outer peripheral side of the case body 1, the impact can be cushioned by the first cushioning member 10 disposed between the case body 1 and the belt attachment portion 3, and therefore, the impact received by the belt attachment portion 3 is not transmitted to the case body 1, and the impact resistance can be improved.
In this wristwatch case, the second cushioning material 12 is provided between the exterior member 11 and the case body 1, so that when the exterior member 11 receives an impact from above, the impact can be cushioned by the second cushioning material 12. Therefore, the impact applied to the belt mounting portion 3 can be reduced, so that the impact can be prevented from being directly transmitted to the case main body 1, whereby the impact resistance can also be improved.
In this case, by providing the decorative member 15 between the exterior member 11 and the screw fixing portion 7, when the exterior member 11 receives an impact from above, the impact can be reduced together with the second cushioning member 12 even by the decorative member 15. When the decorative member 15 is disposed between the exterior member 11 and the screw fixing portion 7, both end portions of the decorative member 15 are exposed to the outside from between the screw fixing portion 7 and the mounting cover portion 13, and therefore both end portions of the exposed decorative member 15 are important in design, and design can be improved.
In the wristwatch case, the first screw member 16 is a stepped screw having a head lower portion 16b inserted into the screw insertion holes 13a and 15a of the exterior member 11 and the decorative member 15 and abutting the screw fixing portion 7, and when the exterior member 11 receives an impact from above, the impact can be reliably and satisfactorily buffered by the second buffer member 12, and thus, the transmission of the impact received by the exterior member 11 to the tape mounting portion 3 can be reduced.
That is, since the first screw member 16 includes the screw portion 16a screwed into the screw hole 7a of the screw fixing portion 7, the head portion 16b inserted into the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11 and the screw insertion hole 15a of the decorative member 15 and brought into contact with the upper surface of the screw fixing portion 7, and the head portion 16c having an outer diameter larger than the inner diameter of the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11, the exterior member 11 can be reliably and satisfactorily mounted to the case mounting piece 5 with the mounting portion 3 by the first screw member 16.
In this case, when the screw portion 16a of the first screw member 16 is screwed and fastened to the screw hole 7a of the screw fastening portion 7, the head portion 16b of the first screw member 16 can be inserted into the screw insertion hole 13a of the mounting cover portion 13 of the exterior member 11 and the screw insertion hole 15a of the decorative member 15 and pressed against the upper surface of the screw fastening portion 7, and therefore the exterior member 11, the second cushion member 12, and the decorative member 15 can be pressed well with a constant pressing force without excessively pressing the exterior member 11, the second cushion member 12, and the decorative member 15 with the head portion 16 c.
Therefore, in the wristwatch case, when the exterior member 11 receives an impact from above, the impact can be reliably and satisfactorily absorbed by the second absorbing member 12, and the impact received by the exterior member 11 is not transmitted to the band attachment portion 3, so that the impact resistance can be further improved.
Further, in the wristwatch case, since the case back 17 is disposed at the lower portion of the case body 1 and the second screw members 19 are screwed into the screw holes 7a of the screw fixing portions 7 from the lower side to mount the case back 17 to the screw fixing portions 7, when the case back 17 receives an impact from the lower side, the impact received by the case back 17 can be reliably received by the case mounting pieces 5 of the pair of tape mounting portions 3, and therefore the impact is not directly applied to the case body 1.
That is, the rear cover 17 is provided with the pair of flange portions 18 disposed at the lower portions of the pair of tape mounting portions 3, and the screw portions 19a of the second screw members 19 are inserted into the screw insertion holes 18a provided in the pair of flange portions 18 and screwed into the screw holes 7a of the screw fixing portions 7 from below, and in this state, the second screw members 19 are fastened, whereby the rear cover 17 can be reliably and satisfactorily mounted to the tape mounting portions 3.
Therefore, in the wristwatch case, when an impact is applied from below to the back cover 17, the impact can be reliably and satisfactorily received by the case mounting pieces 5 of the pair of belt mounting portions 3. In this case, since the rear cover 17 is disposed on the lower surface of the case body 1 via the waterproof packing 17a, when the rear cover 17 receives an impact from the lower side, the impact can be buffered by the waterproof packing 17a, and thus, the impact resistance can be improved.
In this case, since the exterior member 11 is attached to the band attachment portion 3 positioned at the side of the case body 1 by the positioning portion 4 by the first screw member 16 and the back cover 17 is attached by the second screw member 19, the case body 1 can be sandwiched between the exterior member 11 and the back cover 17.
Therefore, in this wristwatch case, even if the exterior member 11 and the back cover 17 receive an impact from the outside, the impact can be received by the band attachment portion 3, and thus the impact is not directly applied to the case body 1, so that the impact resistance can be improved, and the case body 1 can be formed compactly, so that the size of the entire case can be reduced.
In the above-described embodiment, the case where the protrusion 8 is provided on the side of the case body 1 and the engagement recess 9 is provided on the belt attachment portion 3 has been described, but the present invention is not limited to this, and for example, the engagement recess 9 may be provided on the side of the case body 1 and the protrusion 8 may be provided on the belt attachment portion 3.
In the above-described embodiment, the first cushioning member 10 is disposed between the side portion of the case body 1 and the inner surface of the case mounting piece 5, which are located above the protrusion 8 of the case body 1 and above the engagement recess 9 of the tape mounting portion 3, but the first cushioning member 10 may be disposed between the protrusion 8 of the case body 1 and the engagement recess 9 of the tape mounting portion 3, or may be disposed on both sides.
In the above embodiment, the belt coupling piece 6 of the belt mounting portion 3 is configured to protrude from the middle portion of the outer side surface of the case mounting piece 5 to the outside of the case body 1, but two portions may be provided to protrude from both end portions of the outer side surface of the case mounting piece 5 to the outside of the case body 1.
In the above embodiment, the first screw member 16 and the second screw member 19 are screwed into the screw hole 7a of the same screw fixing portion 7, but the screw hole 7a of the screw fixing portion 7 may be provided separately.
In the above-described embodiments, the case of application to a wristwatch was described, but the present invention is not necessarily a wristwatch and can be applied to various watches such as a travel watch, an alarm clock, a desk clock, and a wall clock. The present invention is not necessarily a timepiece, and can be applied to electronic devices such as a mobile phone and a mobile terminal device.
While the present invention has been described with reference to the above embodiments, the present invention is not limited thereto, and includes the inventions described in the claims and their equivalent scope.
