Embodiments for Carrying Out the Invention

[0007] In the following figures, three mutually perpendicular axes are described as the X-axis, Y-axis, and Z-axis. The direction along the X-axis is the "X direction", the direction along the Y-axis is the "Y direction", and the direction along the Z-axis is the "Z direction". The direction of the arrow is the + direction, and the direction opposite to the + direction is the - direction. Note that viewing from the +Z direction or -Z direction is also referred to as a plan view or planar.

[0008] First, the configuration of the clock 1 will be described with reference to FIGS. 1 and 2.

[0009] As shown in FIG. 1, the clock 1 is a wristwatch worn on the user's wrist and includes a cylindrical outer case 2. A dial 3 is disposed on the inner peripheral side of the outer case 2. Of the two openings of the outer case 2, the opening on the front side is closed by a cover glass, and the opening on the back side is closed by a back cover. Note that FIG. 2 shows a state where the back cover 8 is removed. As shown in FIGS. 1 and 2, the cover glass side is the +Z direction, and the back cover 8 side is the -Z direction.

[0010] The clock 1 includes a dial 3, a movement (not shown), an hour hand 4A, a minute hand 4B, and a second hand 4C that indicate time information, all of which are housed inside the outer case 2. A calendar window 3A is provided on the dial 3, and a date wheel 6 is visible through the calendar window 3A. Further, scale marks 3B for indicating time are provided on the dial 3.

[0011] A knob 7 is provided on the side surface of the outer case 2. The knob 7 can be pulled out and moved from the 0 position pushed toward the center of the clock 1 to the 1 position and the 2 position, for example. For example, when the knob 7 is pulled to the 1 position and rotated, the date wheel 6 can be moved to adjust the date. When the knob 7 is pulled to the 2 position, the second hand 4C stops, and when the knob 7 is rotated at the 2 position, the hour hand 4A and the minute hand 4B can be moved to adjust the time.

[0012] As shown in FIG. 2, on the back cover side of the movement, a pressing member 160 is arranged on the outer peripheral side and a ring receiver 170 is arranged on the central side. And, in the vicinity of the balance wheel 7, a speed switch 100 as a rotary switch is arranged. A part of the speed switch 100 can be visually recognized through notches provided in the pressing member 160 and the ring receiver 170 respectively. The speed switch 100 is a switch for adjusting accuracy when a speed difference occurs depending on the environment, as will be described later.

[0013] Next, with reference to FIGS. 3 to 8, the configuration of the speed switch 100 will be described. FIG. 3 is a plan view showing an enlarged view of part A of the clock shown in FIG. 2, FIG. 4 is a perspective view showing the configuration of the speed switch, FIG. 5 is a plan view showing the configuration of the regulating part of the speed switch, FIG. 6 is a plan view showing the configuration of the second receiver provided with the regulating part, FIG. 7 is a cross-sectional view taken along line B-B of the speed switch shown in FIG. 3, and FIG. 8 is a cross-sectional view taken along line C-C of the speed switch shown in FIG. 3. Note that the speed switch 100 shown in FIG. 5 shows a state in which the ring receiver 170 is removed so that the second receiver 210 as a receiving member in the speed switch 100 shown in FIG. 3 is clearly visible. In the description of FIGS. 3 to 8, the back cover side, which is the -Z direction, will be described as the top.

[0014] As shown in the cross-sectional view of FIG. 7, the speed switch 100 is arranged in contact with a circuit board 150 having a speed pattern 151. Specifically, the speed switch 100 includes a guide pin 110, a lever body 120, and a coil spring 130.

[0015] The guide pin 110 is a rod-shaped pin and is fixed to the base plate 11 by being press-fitted into an opening of the base plate 11. The base plate 11 is a plate-shaped member on which clock parts such as gears (not shown) are arranged. The lever body 120 is formed of a metal plate and has an opening 121 into which the guide pin 110 is inserted and a contact part 122 that contacts the speed pattern 151. Further, the lever body 120 has a knob 123 as an operation part for rotating and moving the position of the contact part 122 around the central axis of the guide pin 110. The knob 123 is arranged at one location on the lever body 120.

[0016] The coil spring 130 has an opening 131 into which the guide pin 110 is inserted and is used to press the lever body 120 toward the circuit board 150. A pressing member 160 is disposed on the side opposite to the circuit board 150 with respect to the coil spring 130. The pressing member 160 sandwiches and presses the coil spring 130 between itself and the lever body 120 in order to press the shock switch 100 toward the circuit board 150. The pressing member 160 is also fixed to the base plate 11 with screws or the like.

[0017] Further, the shock switch 100 includes a cylindrical lever shaft 140 formed of a metal material. The guide pin 110 is inserted inside the cylinder of the lever shaft 140. Since the lever shaft 140 is cylindrical, it is possible to increase the range of fitting between the lever shaft 140 and the guide pin 110, and the inclination of the lever shaft 140 with respect to the guide pin 110 can be suppressed.

[0018] Also, the opening of the lever body 120 is press-fitted into the lever shaft 140, whereby the lever shaft 140 and the lever body 120 are fixed. The lever shaft 140 is provided with a flange 141 that abuts against the lever body 120. Thus, since the flange 141 is provided, the position of the lever body 120 can be determined when the lever body 120 is fitted to the lever shaft 140. Further, since the inclination of the lever shaft 140 with respect to the guide pin 110 is suppressed, the inclination of the lever body 120 is also suppressed, so that the posture of the lever body 120 is stable, the contact portion 122 of the lever body 120 can be surely brought into contact with the shock pattern 151, and the posture of the lever body 120 with respect to the circuit board 150 can be kept constant. Specifically, the coil spring 130 is sandwiched between the flange 141 and the pressing member 160.

[0019] As shown in FIG. 7, the guide pin 110 and the pressing member 160 are arranged with a gap therebetween under normal conditions, but it is preferable that they come into contact with each other at the contact portion 13 when an impact is applied to the clock 1 or the like. In this way, since the guide pin 110 and the pressing member 160 are structured to come into contact with each other, it is possible to suppress the extreme expansion and contraction of the coil spring 130, and it is possible to suppress the deterioration of the coil spring 130.

[0020] As shown in FIG. 3, near the slow / fast switch 100, a ring receiver 170 with markings of “+” and “-” and six graduations 12 engraved along the circumferential direction is arranged. By rotating the knob 123 of the slow / fast switch 100 to move the position of the contact portion 122 in the “+” direction or the “-” direction and aligning the position of the knob 123 with any of the graduations 12, the delay and the advance can be adjusted.

[0021] As described above, in the slow / fast switch 100, since the lever body 120 and the coil spring 130 are arranged at different positions, for example, deformation of the lever body 120 during an impact on the clock 1 can be suppressed as in the case where the lever body 120 has a spring function, and the slow / fast switch 100 can be surely pressed against the circuit board 150 side by the coil spring 130. Further, by using the coil spring 130, it is possible to suppress a decrease in the spring force even when an impact is applied to the clock 1 as compared with the case of using a leaf spring, for example. As a result, the logical slow / fast can function appropriately.

[0022] In addition, by adjusting the slow / fast switch 100, accuracy adjustment can be easily performed.

[0023] Also, as shown in FIG. 3, the slow / fast switch 100 includes a regulated portion 201 for restricting the movement of the lever body 120, that is, the slow / fast switch 100 in the rotational direction, between the knob 123 and the contact portion 122 in a plan view. The regulated portion 201 is provided at a position different from that of the knob 123.

[0024] As shown in FIGS. 5 and 6, the restricted part 201 is restricted from moving by fitting into one of a plurality of restricting parts 211 provided in the second receiver 210. The restricting part 211 restricts the movement of the lever body 120 in the rotational direction. The second receiver 210 is a component for sandwiching and holding a part of the wheel train between the floor, and is an example of a receiving member.

[0025] Each of the restricting parts 211 is formed in a shape that is slightly larger than the shape of the restricted part 201, and is formed at a location corresponding to the position of the restricted part 201 when the knob 123 is disposed at any position of the six graduations 12. That is, six restricting parts 211 are formed, which is the same as the number of graduations 12. Further, as shown in FIG. 8, the restricting part 211 is a recess having a depth H1 deeper than the thickness of the restricted part 201 from the upper surface of the second receiver 210.

[0026] Here, the operation of rotating the emergency switch 100 will be described. First, the operator who adjusts the emergency switch 100 loosens a screw near the emergency switch 100 by one pitch among the plurality of screws that fix the pressing member 160 to the floor 11. Then, as shown by the broken line in Fig. 8, the pressing member 160 floats upward. The distance H2 between the knob 123 and the circuit board 150 is larger than the distance H3 between the regulated part 201 and the circuit board 150. That is, the height of the knob 123 is at a position higher than the height of the regulated part 201. Therefore, when the operator rotates the emergency switch 100, with the pressing member 160 floating, the operator lifts the knob 123 with a jig or the like to compress the coil spring 130, and lifts the regulated part 201 higher than the upper surface of the secondary receiver 210. The regulated part 201 disengages from the regulating part 211, and the positions of the knob 123 and the regulated part 201 become the positions shown by the broken line in Fig. 8, and the lever body 120 becomes rotatable. Rotate the knob 123 in the + direction or the - direction and move it to the position of the desired scale 12. When the operator lowers the knob 123, the regulated part 201 fits into one of the regulating parts 211. Finally, the operator tightens the loosened screw to fix the pressing member 160 to the floor 11 again. By fixing the pressing member 160, even if the lever body 120 moves upward due to an impact or the like, the regulated part 201 can be prevented from disengaging from the regulating part 211.

[0027] In this way, since the regulated part 201 is regulated by the regulating part 211, even when there is an impact due to a fall or the like, it is possible to suppress the lever body 120 from moving in the rotational direction, and it is possible to suppress the position of the emergency pattern 151 and the contact part 122 from shifting.

[0028] Also, since the regulated part 201 and the knob 123 are provided at different positions, they can be arranged at appropriate positions or made into appropriate shapes. Also, since the height of the knob 123 is at a position higher than the height of the regulated part 201, the knob 123 can be easily moved without contacting the secondary receiver 210 as the regulating part.

[0029] Next, the configuration of the lever body 120 will be described with reference to Figs. 9A to 9D.

[0030] As shown in FIG. 9A, in a plan view, the lever body 120 has two contact portions 122 arranged diagonally with respect to the opening 121 into which the guide pin 110 is inserted, with the opening 121 as the center. Further, in a plan view, a knob 123 and a regulated portion 201 are arranged on one side of the lever body 120.

[0031] Note that, as shown in the K portion of FIG. 9A, in order to adjust the weight balance, the lever body 120 preferably has a large-area portion 124 on the side opposite to the knob 123 and the regulated portion 201 in a plan view with respect to the opening 121 into which the guide pin 110 is inserted.

[0032] As shown in FIG. 9B, as described above, the contact portion 122 is in electrical contact with the relief pattern 151 of the circuit board 150. The relief pattern 151 will be described later. Note that the contact portion 122 has a shape that is curved in a substantially hemispherical shape, for example, so that the contact between the contact portion 122 and the relief pattern 151 becomes smooth when the knob 123 is rotated.

[0033] As shown in FIG. 9C, the knob 123 is bent upward in an S shape from the surface on which the contact portion 122 is provided. That is, the tip 123a is in a state of floating from the above surface so that the knob 123 can be grasped and rotated easily.

[0034] As shown in FIG. 9D, the regulated portion 201 is bent upward in an S shape from the surface on which the contact portion 122 is provided. As described above, the height of the tip 201a of the regulated portion 201 is lower than that of the tip 123a of the knob 123. Further, the regulated portion 201 is arranged in the concave regulating portion 211 provided in the second receiving portion 210 when the clock 1 is used normally.

[0035] Next, the configuration of the lever shaft 140 will be described with reference to FIGS. 10A and 10B.

[0036] As shown in FIGS. 10A and 10B, the lever shaft 140 is formed in a substantially cylindrical shape as described above. The lever shaft 140 has a first cylindrical portion 142, a flange 141, and a second cylindrical portion 143. The flange 141 is disposed between the first cylindrical portion 142 and the second cylindrical portion 143. The opening 121 of the lever body 120 is press-fitted into the second cylindrical portion 143, so that the lever body 120 is fixed to the lever shaft 140. Further, the upper surface of the lever body 120 abuts against the lower surface of the flange 141, and the height position of the lever body 120 in the axial direction of the lever shaft 140 is determined by the flange 141. A guide pin 110 is inserted into the opening 144.

[0037] Next, with reference to FIGS. 11 and 12, the configuration of the circuit board 150 of the logical acceleration / deceleration method and the logical acceleration / deceleration combination table will be described.

[0038] As shown in FIG. 11, the circuit board 150 is a circuit of the logical acceleration / deceleration method that detects a short circuit of the acceleration / deceleration pattern 151 and performs quantitative correction. Specifically, the acceleration / deceleration pattern 151 has a first acceleration / deceleration pattern 151a, a second acceleration / deceleration pattern 151b, a third acceleration / deceleration pattern 151c, and a fourth acceleration / deceleration pattern 151d.

[0039] In addition, the circuit board 150 is provided with a terminal AS1 connected to the first acceleration / deceleration pattern 151a, a terminal AS2 connected to the second acceleration / deceleration pattern 151b, a terminal AS3 connected to the third acceleration / deceleration pattern 151c, and a terminal AS4 connected to the fourth acceleration / deceleration pattern 151d.

[0040] As shown in FIG. 12, the logical urgency combination table can be adjusted in accuracy in 6 steps as steps, for example, -2, -1, 0, +1, +2, +3. At terminals AS1 to AS4, for example, if they are shorted, it becomes "1". If they are not shorted, it becomes "0". In this embodiment, since the potential of the lever body is set to VSS, if it is "1", it indicates "VSS connection", and if it is "0", it indicates "VDD connection" or "open". These 6 steps respectively correspond to 6 graduations 12, and any one of the 6 - step graduations is selected according to the position of the knob 123 of the urgency switch 100.

[0041] For example, in FIG. 11, the contact portion 122 of the lever body 120 of the urgency switch 100 contacts only the third urgency pattern 151c and does not contact the other urgency patterns 151. In this case, terminal AS3 becomes "1", and the other terminals AS1, AS2, AS4 become "0". Therefore, according to the logical urgency combination table shown in FIG. 12, the step becomes "0", and no time adjustment is performed. This corresponds to the knob 123 being located at the third position from the - side and the fourth position from the + side of the graduation 12.

[0042] For example, in FIG. 11, assume that the contact portion 122 of the lever body 120 contacts both the third urgency pattern 151c and the fourth urgency pattern 151d. In this case, terminal AS3 becomes "1" and terminal AS4 becomes "1". Therefore, according to the logical urgency combination table shown in FIG. 12, the step becomes "+1", and the time can be advanced. This corresponds to the knob 123 being located at the fourth position from the - side and the third position from the + side of the graduation 12.

[0043] Next, with reference to FIG. 13, the configuration of the oscillation circuit 80 including the logical urgency circuit 86 formed on the circuit board 150 will be described.

[0044] The oscillation circuit 80 is composed of, for example, an amplifier 83 such as an inverter, a feedback resistor 84, a gate capacitor 81, and a drain capacitor 82. The power supplied from a battery, which is a power source not shown in the figure, is converted into a voltage Vreg by a power supply circuit and supplied to the oscillation circuit 80.

[0045] The oscillation circuit 80 outputs an oscillation signal of 32 KHz serving as a source oscillation using a crystal oscillator 75 which is a time standard source. This oscillation signal is divided by a division circuit 85 composed of a plurality of frequency dividers (for example, 15 - stage flip - flops) to a predetermined period.

[0046] For time accuracy adjustment, the characteristics of individual crystal oscillators 75 are inspected in advance, and the amount of slack or tension corresponding to each oscillation circuit 80 is set in a logic slack / tension circuit 86. Specifically, by appropriately selecting and short - circuiting the slack / tension patterns 151a to 151d, the amount of slack or tension corresponding to the oscillation circuit 80 is set. In this embodiment, for example, the amount of slack or tension is adjusted by t seconds (sec / day) for each step.

[0047] Also, although the characteristics of the crystal oscillator 75 may change over time, for example, after several years from the manufacture of the clock 1, the characteristics of the crystal oscillator 75 are inspected again, and by rotating a rotary switch according to the changed characteristics and selecting an appropriate slack / tension pattern 151a to 151d, an appropriate amount of slack or tension can be set. Thereby, the time accuracy can be appropriately maintained for a long period.

[0048] As described above, the clock 1 of this embodiment includes a base plate 11 on which clock components are arranged, a circuit board 150 having a slack / tension pattern 151, a slack / tension switch 100 in contact with the circuit board 150, and a regulating unit 211 that regulates the movement of the slack / tension switch 100. The slack / tension switch 100 includes a guide pin 110 fixed to the base plate 11, an opening 121 into which the guide pin 110 is inserted, and a lever body 120 having a contact portion 122 that contacts the slack / tension pattern 151. The regulating unit 211 regulates the movement of the lever body 120 in the rotational direction, and the lever body 120 includes a regulated portion 201 regulated by the regulating unit 211.

[0049] According to this configuration, since the regulated part 201 is regulated by the regulating part 211, even when there is an impact, it is possible to suppress the lever body 120 from moving in the rotational direction, and it is possible to suppress the displacement of the position between the gradual change pattern 151 and the contact part 122.

[0050] Further, in the clock 1 of the present embodiment, the gradual change switch 100 includes a lever body 120 having an opening 121 into which the guide pin 110 is inserted, and a coil spring 130 that presses the lever body 120 toward the circuit board 150 side. It is preferably provided with a pressing member 160 that is disposed on the side opposite to the circuit board 150 with respect to the coil spring 130 and sandwiches and presses the coil spring 130 between the lever body 120. According to this configuration, by arranging the spring and the lever body 120 at different positions and using the coil spring 130 as the spring, it is possible to suppress the reduction of the spring force even when there is an impact, and the gradual change switch 100 can be pressed against the gradual change pattern 151 by the spring. Furthermore, the regulating part 211 can suppress the movement of the lever body 120 in the rotational direction.

[0051] Further, in the clock 1 of the present embodiment, the lever body 120 preferably includes a knob 123 for rotating the gradual change switch 100, and the regulated part 201 is disposed at a position different from the knob 123. According to this configuration, since the regulated part 201 and the knob 123 are disposed at different positions, they can be disposed at appropriate positions or made into appropriate shapes.

[0052] Further, in the clock 1 of the present embodiment, the distance between the knob 123 and the circuit board 150 is preferably larger than the distance between the regulated part 201 and the circuit board 150. According to this configuration, since the distance from the circuit board 150 at the knob 123 is larger than that of the regulated part 201, it is possible to suppress the knob 123 from contacting the regulating part 211, and the operation of the knob 123 is easy.

[0053] Further, for the clock 1 of the present embodiment, it is preferable to include a second receptacle 210 that holds a wheel train, and the regulating unit 211 is provided on the second receptacle 210. According to this configuration, since the regulating unit 211 is provided on the second receptacle 210, the regulated unit 201 can be firmly regulated without moving.

[0054] Hereinafter, a modification of the above-described embodiment will be described.

[0055] As described above, the speed change switch 100 is not limited to using the coil spring 130, and as shown in FIGS. 14 to 17, a leaf spring-like lever body 320 may be used.

[0056] As shown in FIGS. 14 to 17, the speed change switch 300 of the modification is disposed in contact with a circuit board 350 having a speed change pattern 351. Specifically, the speed change switch 300 includes a guide pin 310 and a lever body 320.

[0057] As shown in FIG. 15, the guide pin 310 is fixed to the base plate 11. A cylindrical fitting portion 311 that fits with the opening 321 of the lever body 320 is provided on the upper portion of the guide pin 310. The lever body 320 has an opening 321 into which the fitting portion 311 is inserted and a contact portion 322 that contacts the speed change pattern 351. The speed change pattern 351 is provided on the surface of the circuit board 350 on the side of the base plate 11. The lever body 320 is in the form of a leaf spring, and the contact portion 322 is disposed in a state of being biased toward the circuit board 350 side. In FIG. 15, the broken line portion of the lever body 320 indicates the free state position when the contact portion 322 is not biased.

[0058] Also, as shown in FIGS. 14 and 15, the speed change switch 300 includes a regulated portion 301 for restricting the movement of the lever body 320, that is, the speed change switch 300, in the rotational direction at a position different from the contact portion 322. This regulated portion 301 also serves as a function of an operation portion for rotating the speed change switch 300.

[0059] The restricted part 301 is restricted from moving by fitting into a restricting part 331 provided on a circuit receptacle 330. The circuit receptacle 330 is a member that sandwiches and holds a circuit board 350 between the floor board 11. The restricting part 331 restricts the movement of the lever body 320 in the rotational direction. The circuit receptacle 330 is an example of a receiving member. The restricting part 331 is a concave groove that opens upward so that the restricted part 301 can fit into it.

[0060] In this way, since the restricted part 301 is restricted by the restricting part 331, even when there is an impact, it is possible to suppress the lever body 320 from moving in the rotational direction, and it is possible to suppress the displacement of the position between the gradual change pattern 351 and the contact part 322.

[0061] Also, the gradual change switch 300 of the modified example can have a relatively simple configuration because the restricted part 301 has the function of the operating part as compared with the structure of the gradual change switch 100 of the embodiment. When rotating the lever body 320, it is necessary to lift the restricted part 301 with a jig or the like.

[0062] In this way, it is not limited to the case where the knob 123 as the operating part and the restricted part 201 are arranged at different positions, and the knob 123 and the restricted part 201 may be integrally formed. Also in this case, when rotating the lever body 120, it is necessary to lift the restricted part 201 with a jig or the like. According to this configuration, since the restricted part 201 and the knob 123 are integrally provided, the shape of the lever body 120 can be simplified.
