[0001]

[Technical field to which the invention belongs]

 The present invention is a type of radio clock.In particular, this clock uses a photoelectric element to activate the clock time adjustment function and determine whether the hour, minute, and second hand gears are in the correct position. It is possible to quickly complete the localization of hours, minutes, and seconds.

[0002]

[Prior art]

 The radio clock catches time information emitted from the launch station and uses it as a reference time for time adjustment. As shown in FIG. 1, the main structure of the radio clock includes a functional circuit including an antenna 11, a receiving circuit 12, and a processor 13, and the receiving circuit 12 transmits from the launch station through the antenna 11. The obtained time information is caught and sent to the processor 13. The processor 13 includes control of the work and processing of the time setting process. Generally, after activating the time setting function of the radio clock, the hour, minute, and second hands are adjusted first. To reach the localization point. This is generally adjusted to the position of 0 (12): 0: 0. After that, the hour, minute, and second hands are moved to the position corresponding to the time information based on the time information that was caught. The localization operation of adjusting the hour, minute, and second hands to the home position is a process controlled by the localization mechanism, and the radio clock is a mechanical clock that drives the hour, minute, and second hand gears by a motor. In general, a method of determining whether or not the hour, minute, and second hand gears are in a fixed position is mainly performed by using a photoelectric element, and a method of determining whether the gear is in a normal position is performed by using a photoelectric element. Things. As shown in FIG. 1, this radio clock uses two motors 14, 15 to drive the second hand gear and the minute hand gear, respectively, and the minute hand gear further activates the hour hand gear. . This activates the hour, minute and second hands of the radio clock, and the two photoelectric elements perform the localization of the second and hour hands, respectively, using the localization identification points on the second and hour hand gears. 2), only the hour and minute hands are shown in FIG. Using the photoelectric element 16, the localization identification point 17 of the hour hand gear 18 is detected, and when the photoelectric element 16 detects the localization identification point 17, the hour / minute hands corresponding to the minute hand gears 18, 19 are: It reaches the position of 0 (12) 0: 0 promptly. Similarly, the second hand uses this technical means to set a localization discrimination point on the second hand gear and detect it using the photoelectric element. Using the photoelectric element in this way, it is determined whether the hour, minute, and second hands are at the home positions. Considering the case where the radio clock activates the time setting function at 1:00, the second hand gear will rotate at most once (assuming that the second hand is at the position of 0 second) and will be localized at 0:00. It is necessary to return to the point, the minute hand rotates 11 times, and return the hour hand to the home position at 0 o'clock. For this reason, the operation of returning the hour, minute, and second hands to the localization point using a conventional radio clock often causes a considerable loss of time. The return of the minute hand, minute hand and second hand to the localization point, and the use of only the photoelectric element can reduce the cost, which has a positive meaning.

[Embodiment of the invention]

 Hereinafter, the present invention will be further described with reference to the drawings, but the present invention is not limited thereto.

[0007] The hour, minute and second hands of the radio clock according to the present invention drive the hour, minute and second hand gears with a motor like a conventional mechanical clock. The localization mechanism that returns the minute and second hands to the localization point uses the photoelectric element to determine whether the hour, minute, and second hands have returned to the home position. The feature of the present invention is that the localization mechanism guides the corresponding three gears by the hour, minute, and second hand gears, and determines whether the photoelectric element has the hour, minute, and second hand gears at the localization point. . As shown in FIG. 3, the contents of the radio clock according to the present invention include the hour, minute, and second hand gears 21, 22, and 23, and the hour, minute, and second hand gears 21, 22, and 23 are included. Is operated by a rotor 26, and the rotor 26 is rotated by driving a motor. Here, the second hand gear 21 is rotated by the motor 24 rotating the rotor 26, and the hour / minute gear 22 is rotated by the motor 25 rotating the rotor 26. Further, the minute hand gear 22 operates the hour hand gear 23 via the reduction gear 27. Thus, the hour, minute, and second hands corresponding to the hour, minute, and second hand gears are moved, and the hour, minute, and second hand guide gears 31, 32, and 33 are guided by the engagement of the hour, minute, and second hand gears 21, 22, and 23. . At this time, the hour, minute and second light shielding gears 34, 35 and 36 are installed in the hour, minute and second hand guiding gears 31, 31 and 33, and the hour, minute and second light shielding gears 34, 35 and 36 have: The convex light-shielding chips 341, 351 and 361 are provided. At this time, the hour, minute, and second light-shielding gears 34, 35, and 36 are installed in the form of thin sections in close proximity, and the optical path of the photoelectric detector 37 can detect the hour, minute, and second light-shielding chips 341, 351 and 361. . The photoelectric detector 37 includes a receiver 38, and emits light toward the receiver 38. When receiving the optical path emitted from the photoelectric detector 37, the receiver 38 maintains the potential (temporarily set as a low potential), and when this receiver does not receive the optical path emitted from the photoelectric detector 37, Turns to high potential. The present invention uses the light-shielding chips 341, 351, and 361 to intercept the optical path emitted from the photoelectric detector 37 and to introduce the light into the receiver 38. Is to judge. When the light-shielding chips 341, 351, and 361 of the hour, minute, and second gears block the optical path from which the photoelectric detector 37 emits light, the corresponding hour, minute, and second hands are positioned at stereotactic points. It is difficult to detect the hour, minute, and second hand gears by using only one photoelectric element in the clock operation with the current mechanical gear, but in the present invention, the hour, minute, and second gears 21, 22, and 23 are engaged. By guiding the hour, minute, and second guiding gears 31, 32, and 33, the light shielding gears 34, 35, and 36 are installed near the hour, minute, and second guiding gears 31, 32, and 33 to respond to this. The hour, minute, and second gear light-shielding chips 341, 351, and 361 are detected by the photoelectric detector 37, and by using only one photoelectric element, the hour, minute, and second hands are positioned at the localization points. It can be determined whether or not it has arrived.

As shown in FIGS. 3 and 4, the radio clock of the present invention uses only one non-photoelectric detector to determine whether the hour, minute, and second hands are in the normal position. is there. Since the detection position of the photoelectric detector 37 is fixed, the photoelectric detector 37 cannot simultaneously detect the hour, minute, and second gear light shielding chips 341, 351 and 361. When detecting the localization of the hour, minute, and second gear light-shielding chips 341, 351, and 361, it is necessary to detect and determine the hour, minute, and second gear light-shielding chips 341, 351, and 361 one by one. The detector 37 can complete the detection and determination of the hour, minute, and second gear light shielding chips 341, 351 and 361. As a relatively good embodiment of the present invention, first, the second gear light-shielding chip 361 is detected, and after the second gear light-shielding chip 361 is detected, the second gear light-shielding chip 361 rotates at a certain distance (ie, (Operating for several seconds), leaving the detection position of the photoelectric detector 37, thereby completing the localization of the second hand. Thereafter, the hour / minute hand motor 25 drives the minute hand gear 22 and the photoelectric detector 37 starts detection of the hour / minute light-shielding chips 341 and 351. Regarding the determination of when the hour and minute gears return to the normal position, the photoelectric detector 37 can first detect the hour gear light-shielding chip 341 and then subsequently detect the minute gear light-shielding chip 351. When the minute gear light-shielding tip 351 is detected, that is, this is the completion of the localization of the hour and minute hand gears. As a result, the present invention can detect the localization of the hour, minute and second hands by using one photoelectric detector.

In order to promptly complete the localization of hours, minutes, and seconds with the radio clock of the present invention, the present invention employs the first, second, and third light-shielding chips 341, 342, If the first light-shielding chip 341 is located at a position where the first light-shielding chip 341 blocks the photoelectric detector 37, the corresponding hour hand is located at the first time point (see FIG. 4). Time position). Similarly, the second light-shielding chip 342 is located at the second time point (4 o'clock position), and the third light-shielding chip 343 is located at the third time point (8 o'clock position). Using the difference in the width of the first, second, and third light-shielding chips, that is, the difference in the time in which the first, second, and third light-shielding chips 341, 342, and 343 block the optical path, the processor can determine By judging whether the light-shielding tip is blocking the optical path, it is possible to know at which point the localization point of the corresponding hour hand is located, whereby the localization of the hour and minute hands can be completed promptly. it can . As an example, assuming that the time adjustment function is activated at 1:00, the radio clock of the present invention stops the operation of the timekeeping, and at this time, the photoelectric detector 37 shifts the hour, minute, and second gears. The detection of the light-shielding chip is started. If the hour, minute, and second gear light-shielding chips are not detected, the hour / minute motor 25 stops operating, and the second hand motor 24 continues driving to move the second hand gear 23. When the second hand gear 23 makes one revolution, the corresponding second gear light-shielding chip 361 also makes one revolution so that the optical path of the photoelectric detector 37 can be interrupted, and the processor immediately notifies the motor 24 to stop driving. However, before the driving is stopped, the second gear light-shielding chip 361 slightly advances and moves from a position that interrupts the optical path. This allows the hour and minute gear light-shielding chip to block the optical path of the photoelectric detector 37. After the second hand returns to the localization point, the motor 25 drives the minute hand gear 22 and the photoelectric detector 37 starts detecting the hour gear light shielding chip. When the minute hand gear 22 makes three turns, the second light-shielding chip 342 of the light-shielding gear 34 corresponding to this makes it possible to block the optical path of the photoelectric detector 37. Recognizes that the corresponding hour hand is at 4 o'clock. Thereafter, when the photoelectric detector 37 detects the minute gear light-shielding chip 351, it notifies the motor 25 of the drive stop, thereby completing the return of the localization points of the hour, minute, and second hands. At the same time, the processor recognizes that the hour hand is at 4 o'clock and the minute and second hands are at 0 o'clock (12). Thereafter, after the number of seconds of the received time information reaches 0 o'clock, the processor or the like starts the motor 24 and adjusts the second hand to the number of seconds of the reference time. During this time, the processor controls the motor 25 to set the hour and minute hands to the hour and minute of the time information received by the processor, thereby completing the time setting operation. After this, the hour, minute and second hands continue to operate normally like a general clock. Thus, the time setting function of the radio clock of the present invention is activated by moving the minute hand gear up to three turns (when activated at 12, 4, and 8 o'clock) to advance the localization of hours, minutes, and seconds. Once completed, the localization time of the hour, minute, and second hands can be significantly reduced compared to the conventional method.

[0010] Radio clocks have already been proven in Europe and the United States, and all the main receiving circuits and functional circuits based on processors can use corresponding ICs. Therefore, this is not described in the present invention. Also, the feature of the present invention is that the localization mechanism uses one photoelectric detector to detect whether the hour, minute, and second gears have reached the localization. Using the hour, minute, and second guiding gears that are guided by the meshing of the gears, install the hour, minute, and second shading gears in close proximity, and use only one photoelectric detector to display the hour, minute, and second hands. At the same time, three sets of light-shielding chips, such as an hour gear and a light-shielding gear, can return to the normal position with a maximum of four rotations of the minute hand. The radio clock of the present invention has further commercial value because it can greatly reduce the time required for stereotactic return as compared with the conventional method.

To summarize the above, the present invention has novelty and practicality, and meets the requirements of a utility model.

The above is the detailed description of the present invention. However, the above description is merely an example of the present invention, and the present invention is not limited thereto. All changes and modifications in the utility model registration claims of the present invention shall belong to the scope of the present invention.
