First, an electronic watch with a hand display according to the present invention will be explained in general.

As can be seen from the block diagram of FIG. 1, the clock according to the present invention has a quartz crystal oscillator Q, an electronic circuit E, an oscillation circuit 0, a frequency divider D and an output controller

C contains, connected to the vibrator Q, a movement or movement M with a pulse motor P and a display mechanism I, which is connected to the electronic circuit E, a battery

terie B for the supply of energy to the circuit E and a function selection switch S for the control of the Circuit E on.

As can be seen from the circuit diagram of FIG. 2, the watch according to the present invention includes two function _{selection switches, one of which is a quick switch S 1} and the other is a reset switch S ^. These two switches control separate circuit arrangements which are each designed as MOS-LSI elements, that is to say as highly integrated circuits with a MOS structure. In other words, the MOS-LSI element is connected to the two switches S .. and S2, the quartz crystal vibrator Q, a drive coil 10 for running the pulse motor P and the battery B at their respective terminals. In the element, the oscillation circuit O, the frequency divider D and the output controller C are formed. Numeral 12 represents a rotor in the pulse motor; a minute wheel 14 in the above-mentioned display mechanism is driven by the rotor 12; the hour and minute hands 16 and 18, respectively, are driven by means of the minute wheel 14.

In the following, with reference to Figure 3, the electronic circuit E for the clock according to the present invention will be explained in detail.

If the quick switch S .. and the reset switch S- themselves not in their ON state or in their conducting state, output pulses are provided by a 60-digit system counter 20 for counting 1 Hz pulses which are supplied by the frequency divider D, finally from an output 28 as normal pulses for the actuation or movement of the pointers by an AND gate 22, an OR gate 24 and a circuit 26 supplied to interrupt the output pulses, the output pulses having a period of one minute. The two hands are operated or moved step by step every minute.

809808/0910

"" "273707b

When the quick switch S .. is turned ON and OFF in a short period of time by some external operating means such as a button (not shown), a switch compensation circuit 30 generates specific electrical signals at the time of turning on. These signals activate a "shot" signal generator 32, and the "shot signals" are supplied from the output 28 through the OR gate 24 and the stop circuit 26 for the output pulses. These shot or step signals can move the two pointers step by step with each ON / OFF actuation of the quick switch S _1.

If the fast switch S, is held in the ON state, pulses for fast forward (such as 8 Hz pulses) from the frequency divider D as output pulses in the same way by the AND gate 36 after a predetermined Time span (2 or 3 sec.) Is supplied by means of a time switch mechanism 34 so that both pointers are moved quickly can.

When the quick _{switch S 1 is} turned off after its ON state has been maintained for some time, the output pulse stop circuit 26 comes into action to interrupt the output pulses, as a result of which the pulse motor is disabled.

When the reset switch S ₂ is brought to the ON state by an external operating device (not shown) in the idle state of the pulse motor, a switch compensation circuit 38 generates a specific output signal which is fed through an AND gate 40 to a signal separator 42; the signal from the signal separator is stored in a start memory 44. On the other hand, a pulse from the 60-digit system counter 20 drives a timer 46, an output signal of this timer being applied to the start memory 44 through a signal separator 48 and an AND element 50. The stored in the start memory 44

809808/0910

- 12 -

273707b

stored signal is read out and applied to the stop circuit 26 for the output pulses to the circuit from the blocked to the conductive state. The result of this is a pulse from the 60-digit system counter 20 supplied as a normal output signal from the output 28, so that the pulse motor after a period of one minute is switched to its normal operating state.

If the reset _{switch S 2} is switched on twice in the pulse inhibit state during a certain period of time, for example in 10 minutes, which is set by the timer 46, two signals from the signal separator 42 are stored in the start memory 44. Two output pulses are then generated by the 60-digit system counter 20, and the signal read out in the start memory 44 is formed after these two pulses have been received. As a result of this, the stop circuit 26 for the output pulses is switched to the conductive state after a period of 2 minutes.

In this way, the normal operation or adjustment of the pointer can be carried out after one minute by ON / OFF operation of the reset switch S ₂ once in a certain period of time (in 10 seconds) or after two minutes by ON / OFF operation twice or start after three minutes by pressing the ON / OFF button three times in the same period of time. For the four or more ON / OFF actuation, the start memory 44 is designed so that these periods of the delay time are repeated, as described above and which are determined by the one to three ON / OFF actuation in the predetermined period of time .

With this arrangement, the time-consuming and laborious setting of the time, which otherwise had to be carried out, can be by turning the hands quickly over twelve hours or waiting a few minutes, by starting the normal

paint adjustment of the hands, for example two or three minutes later, in the event that the clock goes several minutes ahead, by _{simply turning the reset switch S 2} on and off.

If, furthermore, the reset switch S _{2 is switched} on during normal actuation or movement of the pointer, a signal from the switch compensation circuit 38 is passed through the signal separator 42 to a 30-second divider circuit 52. When the counting time by the 60-digit system counter 20 rises from "0" to +30 sec. is sufficient, the counter 20 is reset to "0" by the 30-second divider circuit 52, while the counter 20 is reset by one step to "0" after the application of a pulse for driving the pulse motor when the counting time reaches +30 up to +59 sec. enough.

In this way, a time lead or a delay in the range of 30 seconds. correct by pressing the reset switch S _2.

So far, the electronic switch E in the timepiece according to the present invention has been described in detail with reference to FIG. 3 has been described.

In the following, the work M, as it is constructed in practice, will now be explained with reference to FIG. 4; this work M, the output pulses from the electronic circuit E are fed.

As can be seen from Fig. 1, the work M includes the pulse motor P and the display mechanism I. The output pulses from the output 28 shown in Figure 3 are applied to the drive coil 10 of the pulse motor P; the rotor 12 is driven or rotated by every single pulse that is sent to the pulse motor P, an electromechanical converter, is created. The rotor is indicated in Fig. 4 by the reference number

Chen 12, the reference numerals 14, 16 and 18 denoting the minute wheel, the hour hand and the minute hand, respectively mark. The rotation of the rotor 12 is transmitted to the minute wheel 14 through a rotor pinion 60. The minute hand 18, which is attached to the tip of a minute wheel shaft 62, is shared by each output pulse from the output 28 moves. A minute wheel pinion 64 attached to the minute wheel 14 is attached, comes into engagement with a third wheel and pinion 66, which has a third wheel pinion 68, the is engaged with an hour wheel 70. The hour wheel 70 rotates around the minute wheel shaft, while the hour hand 16 is attached to the end of an hour wheel tube 72. In other words, the rotation of the minute wheel 14 becomes through the third wheel and pinion 66 is reduced by 1/60 before it is transferred to the hour wheel 70.

As described above, the electronic watch with hand display according to the present invention enables the time to be set by electronic control without using a conventional complicated mechanism for adjustment the pointer; thereby a simple construction, a reduction in size and a simplification can be achieved of manufacture by simply adding multiple pulse control circuits to the existing MOS LSIs will.

In the following, a pulse motor will be described in detail, as it is in an electronic watch with a pointer display is used in accordance with the present invention.

Conventional pulse motors of this type have, for example, a structure as shown in Figs. 5A and 5B. Fig. 5A shows a perspective view of such a pulse motor, while Fig. 5B shows a plan view of the pulse motor of Fig. 5A. In Figures 5A and 5B, the rotor is provided with the reference number 101. The rotor 101 rotates around a shaft 101a and has the shape shown in Fig. 6, wherein

809808/0910 - 15 -

273707b

six magnetic axes are formed parallel to the shaft 101a, which constantly rotate by magnetization. These Magnetic axes are generated along a cylinder X, indicated by dashed lines, in the center of which the shaft 101a lies; the magnetic axes are at angular intervals of 60 ° with alternating magnetic poles NS ... on the upper and lower side surfaces of the rotor 101 such alternating magnetic poles occur after 60 ° in a circle or with a phase difference of 60 °. A rotor pinion 101b is attached to the shaft 101a of the rotor 101 to transmit its rotation.

Two upper stators 102a and 103a in one plate are provided above the rotor 101 at right angles to the shaft 101a. The upper stators 102a and 103a have two upper, opposite portions a 1 and a 2 which are arranged symmetrically with respect to the shaft 101 a so that they face the magnetic poles of opposite polarity on the upper surface of the rotor 101. Two lower stators 102b and 103b in one plate are similarly provided under the rotor 101 perpendicularly and orthogonally to the shaft 101a, respectively. The lower stators 102b and 103b have lower, opposite portions b ₁ and b 2 which are symmetrically arranged with respect to the shaft 101 a so that they face the magnetic poles of opposite polarity on the lower surface of the rotor 101. The upper, opposite area a ₁ is shifted or offset by an angle of 60 ° from the lower, opposite area b .., while the upper, opposite area a2 is displaced by the same angle of 60 ° from the lower, opposite area b ₂ is shifted or offset.

A spacer 104 is between the upper and lower stators 102a and 102b while a spacer 105 is held between the upper and lower stators 103a and 103b is. The spacers 104 and 105 each consist of

- 16 -

809808/0910

273707b

several magnetic sheets or magnetic foils and serve to bil a space between the upper and lower stators and to couple them magnetically. The spacers 104 and 105 do not consist of a single part, but of several sheets or foils made of magnetic material, which are combined to form a laminate or laminated core to to reduce the eddy current losses that can be generated by drive pulses.

The upper stator 102a, the spacer 104 and the lower stator 102b are thus combined into one set; this Set is attached to one side of a yoke 106, while the upper stator 103a, the spacer 105 and the lower Stator 103b as one set on the other side of the yoke 106 are appropriate. The drive coil 107 is mounted around the yoke 106 so that the coil 107 is magnetically connected to the upper or lower stators 102a, 102b or 103a, 103b can be coupled. As a result, the top Stator 102a, spacer 104, and lower stator 102b are magnetized with one polarity. The upper stator 103a, the Spacer 105 and the lower stator 103b are magnetized with the opposite polarity.

In Figures 5A and 5B, reference numerals 108 and 109 denote machine screws with which the upper and lower Stators can be combined with the spacer to form a single body, that is, to form a unit; with the Reference numerals 110 and 111 are screws that secure the yoke 106 to the spacer and the lower stator can be firmly connected. With the reference numerals 112 to 115 are provided with holes that receive reference pins for positioning. Such reference pins are on every facility provided on which the pulse motor is attached.

If the upper, opposite areas a ₁ and a _? of the upper stators 102a and 103a respectively face different magnetic poles on the upper surface of the rotor 101 are shown in FIG

809808/0910

Z / J / ο / υ

similarly the lower, opposite areas b. and b _{2 of} the stators 102b and 103b face different magnetic poles on the lower surface of the rotor 101, respectively. As already mentioned above, there is a phase difference of 60 ° between the upper and lower opposite areas a .., a ₂ and b., B ₂ , so that as a result of this, the upper, opposite area a, and the lower, opposite Area b. facing identical magnetic poles. The upper and lower opposite areas a? and bj face other magnetic poles in a similar manner. Thus, when alternating current pulses are applied to the drive coil 107, the upper and lower stators 102a and 102b are alternately magnetized with polarity N or S, i.e. to north and south poles, while the upper and lower stators 103a and 103b alternate with polarity S and N are magnetized, so south poles or north poles. At the four opposite areas a ,, a ₂ , b. and by of the upper and lower stators, there occurs such magnetic attraction and repulsion between the rotor 101 and these portions that the rotor 101 can rotate in either direction. In this way, the rotor 101 can be driven stepwise by a magnetic pole with each pulse.

Conventional pulse motors with the structure and mode of operation described above require separate fastening means for the two sets of spacers, the upper and lower stators being these spacers hold between them.

In order to properly attach a single set, two holes must be made around the single set to position; furthermore, two, generally as many as there are holes, must have reference pins on each Device or any object to which the pulse motor is attached. The difficulties with the However, the design and design increase with an increase in the number of reference pins, as is the case, for example, with arm

809808/0910 _ ₁₈ -

2 7 3 7 Q 7 b

tape watches and similar instruments is the case where the pulse motor is housed in a limited space got to. The pulse motor shown in Figures 5A and 5B requires four reference pins, which can be found with great difficulty arrange and have them attached.

Furthermore, as described above, each spacer must consist of several sheets or foils of magnetic material getting produced. This can cause small differences in the thickness of each spacer sheet and too cause great difficulty if the pairs of opposing portions of the stators work in the desired manner should be set in their position. Such conventional pulse motors had to be adjusted and adjusted very precisely can be set.

Furthermore, the spacers of conventional pulse motors, as shown in Figures 5A and 5B, can be made of magnetic material. This represents Another disadvantage is that this material is difficult to work with.

Referring to Fig. 7, an embodiment of a pulse motor according to the invention will now be described in detail will.

The pulse motor shown in Fig. 7 instead of the spacers 104 and 105 of the pulse motor shown in Figs. 5A and 5B a spacer 116 and extensions of the individual stators. The spacer 116 is not off magnetic material, but made of non-magnetic material and consists of a single part, so is not separated into two sections as was the case with spacers 104 and 105 of Figures 5A and 5B. The extensions are areas of the individual stators that are arranged so that they can be magnetically coupled to a drive coil 107 without this being caused by the Spacer 116 must be done. The upper and lower ver

809808/0910

" ¹⁹ " 273707b

Extensions hold between them on both sides a yoke 106 with magnetic spacers 117, which under the yoke 106 are attached. These parts are secured with screws 110 and 111 running through them. The screws 110 and 111 serve in common with the screws 108 and 109 for the assembly of the pulse motor.

In the pulse motor shown in FIG. 7, the single spacer 116 and the upper and lower stators 102a, 102b and 103a, 103b holding the spacer between them can be integrally assembled as a unit. Only the two holes 113 and 115 are required to position this unit. Therefore, in comparison with the conventional pulse motors, as shown in Figures 5A and 5B, the number of reference pins can be reduced.

Furthermore, in the case of the pulse motor according to FIG. 7, the spacer 116 is made in one piece and from a non-magnetic material. This simplifies the production of such a spacer 116 with a uniform thickness, so that the opposite areas a ₁ , a 2 and b, b ₂ can be attached in their position in a suitable manner. Such a pulse motor therefore does not require any subsequent adjustment.

In the pulse motor shown in Fig. 7, however, the problem arises that the drive coil 107 is only with Difficulties and a certain amount of effort can be removed. In other words, the pulse motor shown in Fig. 7 has Stator extensions magnetically coupled to drive coil 107. To carry out this coupling the yoke 106 must be held between the upper and lower extensions as mentioned above. at In such an arrangement, all screws 108, 109, and 111 must be removed to secure the upper stators 102a and 103a can be removed when the drive coil 107 is removed

809808/0910 - 20 -

shall be. This is a disadvantage.

In the pulse motor shown in Fig. 8, this disadvantage is overcome by a curved portion of the upper Stator is arranged over and on the associated lower stator. In other words, are in the pulse motor According to FIG. 8, the extensions of the upper stators 102a and 103a are bent like a crank or clamp or staple, so that they are placed on the extensions of the lower stators 102b and 103b, respectively. The yoke 106 is on Both ends are mounted on the extensions placed over them and are then fastened with screws 110 and 111 .

In the pulse motor shown in Fig. 8, the drive coil 107 simply remove by unscrewing screws 110 and 111 without removing the upper stators 102a and 103a must be removed. The removal of the drive coil 107 is therefore considerably simplified. In this way, a pulse motor can be manufactured which can be easily installed in which the drive coil can be easily removed and does not require adjustment.

In the embodiment of FIG. 8, the extensions are the upper stators 102a and 103a are bent like a crank and lie above and on the lower stators 102b and 103b, while the yoke 106 is mounted thereon. Alternatively, the extensions of the upper stators 102 a and 103 a be arranged so that each against the side surfaces of the Push yokes 106 without being over the upper stators 102a and 103a on the lower stators 102b and 103b. In this case, the drive coil 107 can also be easily removed. The pulse motor according to the present The invention is therefore not limited to the embodiment shown in FIG. 8, in which a region of the upper stator is magnetically coupled to the drive coil and is bent,

809808/0910

- 21 -

2737Ü7B

to make it easier to dismantle the drive coil.

Conventional pulse motors of this type that are built into wristwatches have stators that are quite are thin or up to about 0.2 mm thick. Such stators are arranged so that they are attached to the two Sides of spacers are attached with screws. When the screws are tightened, the stators will go up bent or twisted or curved, in particular on the edge of the opposite areas of the stators, which are far removed from the screws. Fine adjustment must therefore be made in such stators.

This disadvantage can be avoided by evenly fastening the stators with several screw pieces. From a construction point of view, however, it is relatively difficult to add another screw to a device with a high density of components, such as wristwatches to use.

The pulse motor shown in Fig. 9 overcomes this difficulty by dividing a spacer into two parts, one part of which is attached to the upper stators and one Part is attached to the lower stators.

This pulse motor has two upper and lower spacers 118 and 119 which, by dividing the spacer 116 of the pulse motor shown in Fig. 8 can be formed. The upper stators 102a and 103a are on the upper side of the upper spacer 118 attached while the lower stators 102b and 103b are attached to the lower side of the lower spacer 119. This can be done by spot welding or a connection with an adhesive.

This pulse motor is assembled by first attaching the lower spacer 119 to which the lower stators 102b and 103b

809808/0910

2 I J / U / b

attached, placed in position; then the rotor 101 is inserted into a central opening 119a on the spacer 119 inserted, the upper spacer 118 on which the upper stators 102a and 103a are attached to the lower spacer 119, and finally they are secured with screws 108 and 109 as with the pulse motor attached according to Fig. 8.

The pulse motor shown in Fig. 9 thus has thick spacers on which thin stators are attached. This prevents the stators from being tightened of the screws 108 and 109 are bent or curved.

Thus, the pulse motor of the present invention can be manufactured without the need for fine adjustment is because the opposite areas of the individual stators are easily inserted directly into the desired position can be. In addition, this pulse motor is extremely resistant to vibrations and shocks, since its spacers serve as reinforcement plates. And finally, it is easy to assemble.
