During the swing operation of the head 3, when a force against the swing operation of the head 3 is applied, or when a force against the swing operation of the head 3 is applied, the bottom of the head 3 and the first Engaging portion 31b of lever 31
Are separated from each other against the elastic force of the spring 37, and the spring 37 functions as a safety device.

The up and down movements of the pupils 11a, 11a are interlocked with the up and down movement of the front side of the head 3, and the appearance is as if they were dozing while seeing this action from the front of the robot body. Will be presented.

Next, a drive mechanism for wake-up operation in which the head 3 of the robot body swings largely and the arm 101 rotates will be described.

The wake-up operation is activated when the reference switch provided in the timepiece movement 9 is closed at a preset time and when the push button 5 provided on the upper surface of the head 3 is operated. In any case, it is in a state in which it can be operated only when the alarm activation switch 69 projecting from the back surface of the body 1 is closed. Switch 69
Is slidably provided in an enclosure (not shown) defined by a ridge on the back surface of the body 1, and an elastic plate 71 is mounted on the top of the enclosure. The elastic plate 71 has a protrusion bent in a V shape at the center thereof, and the protrusion protruding from the upper edge of the slide plate 69a engages with this protrusion to position the moving position of the switch 69. ing. (6th
That is, when the switch 69 is slid in the leftward direction shown in FIG. 6, the protrusion of the slide plate 69a moves over the dogleg-shaped protrusion of the elastic plate 71 and moves to hold the position.
The projecting piece 69c protruding from the end of the 69a presses the electrically conductive contact piece 73 so that the electrically conductive contact pieces 73 and 75 come into contact with each other, and the switch 69 for performing the wake-up operation is closed. Further, when the switch 69 is moved in the rightward direction shown in FIG. 6, the slide plate 69a
The protrusion of (1) moves over the protrusion of the elastic plate 71 and moves, the conductive contact pieces 73, 75 are separated, and the switch 69 is opened. As the switch 69 moves to the right, the slide plate 69
The projecting piece 69b projecting from a is in contact with the side surface of the second cam 57 and slides the second cam 57 in the axial direction of the support shaft 49 (rightward direction in the sixth illustration). Further, the elastic projection 69d protruding from the side surface of the slide plate 69a is the slide plate 6 which reaches the right limit.
This is a return spring for stopping the 9a by the protrusion of the slide plate 69a coming into contact with the protrusion of the elastic plate 71, and the details of the operating state will be described later.

When the reference switch in the timepiece movement 9 is closed at the time set by the knob 25 while the wake-up operation switch 69 is closed, the second motor 119 is driven to start the wake-up operation. The gear 115, which is linked to the motor pinion 119a of the second motor 119 via the transmission gear, is loosely fitted to the gear shaft 103 which is slidable in the axial direction. (Fig. 3)
The gear 115 meshes with the gear 113 pivotally attached to the gear shaft 67, and the gear 65 pivotally attached to one end of the gear shaft 67 is
A cam 57 and a third cam 61 mesh with a gear 59 integrally formed on both sides. The second cam 57, the third cam 61, and the gear 59 are pivotally attached to the support shaft 49. A gear 97 is loosely fitted to the other end of the gear shaft 67, and a pin 97a erected on the side surface of the gear 97 fits into a long groove 93b of a rotating member 93 loosely fitted to the support shaft 95. ing. Therefore, when the second cam 57 rotates in the direction of the arrow shown in the third figure, the pin 45a of the second lever 45
By engaging with the cam projection 57 of the second cam 57, the second lever 45 swings around the gear shaft 67 as a fulcrum. The pin 45b protruding from the tip of the second lever 45 is in contact with a position close to the support shaft 33, which is the fulcrum of the first lever 31, and the swinging operation of the second lever 45 causes the first lever 31 to swing relatively. It performs a large swing operation. The swinging operation of the first lever 31 with a large amplitude causes the front side of the head 3 to largely move up and down.

The crank-shaped rotating member rotatably attached to the gear shaft 103 has a spiral protrusion 107 projecting from the peripheral surface, and the engagement pin 106 formed at the tip end serves as a cam protrusion of the third cam 61. Engage. When the rotating member 105 rotates due to the engagement pin 106 engaging with the cam projection of the third cam 61, the ridge 107 engages with the engagement projection 109 provided on the machine frame 39, and the gear shaft 103 Gear shaft 10
It slides in the rightward direction shown in FIG. 3 against the elastic force of the push spring 111 wound around 3. The pinion 117, which is attached to the tip of the gear shaft 103 that slides in the rightward direction, meshes with the gear 97 and
To rotate. Further, the gear shaft 103 has a third rotary member 105.
When engaging with the cam 61 and rotating, it rotates while sliding in the rightward direction in FIG. 3, and when the engaging pin 106 does not engage with the protrusion of the third cam 61, The elastic force has returned to the leftward direction shown in FIG. Therefore, the gear 97 that engages and disengages with the pinion 117 meshes only when the gear shaft 103 slides in the rightward direction shown in FIG.
97 is the one that rotates intermittently.

The rotating member 93 in which the pin 97a erected on the side surface of the gear 97 is fitted in the long groove 93b, the rack 93a is engraved on the protruding portion on the arc, and the rack 93a has a cylindrical mounting member 89. It meshes with a gear 87 which is axially attached to the base end. A disc-shaped collar plate 91 is formed at the center of the mounting member 89. This guard plate 91
Projections 91b, 91b are provided on the outer peripheral surface of the projections 91b, 9b.
Arc-shaped slot holes 91a, 91a are formed inside 1b.
The tubular portion 99 to which the arm portion 101 is attached is fitted to the collar plate 91.
A pair of recessed portions 99a, 99a are formed on the inner peripheral surface of the tubular portion 99, and the recessed portions 99a, 99a are fitted into the projections 91b, 91b of the collar piece 91, and the groove holes 91a, 91a. When the arm 101 is forcibly rotated, the outer peripheral edges of the slots 91a and 91a are bent to allow the arm 101 to rotate, and has a function of a safety device. Therefore, the arm portions 101, 101 fitted to the mounting members 89 pivotally attached to both ends of the support shaft 47 intermittently move up and down. Then, this wake-up operation moves the head 3 up and down to move the arms 101, 101.
And the sounding mechanism provided in the timepiece movement 9 is activated, and a predetermined alarm sound is emitted from the speaker.

To stop the wake-up operation, the switch 69 may be moved in the rightward direction shown in FIG. 6 to separate the conductive contact pieces 75, 75 from each other. The protrusion 69b protruding from the slide plate 69a of the switch 69 reaching the right limit engages with the side surface of the second cam 57, and the cam protrusion of the second cam 57, the pin 45a of the second lever 45 and the gear 59. The second cam 57 is moved to a position where the gear 65 and the gear 65 are separated from each other. Since the support shaft 49 on which the second cam 57 separated from the pin 45a is pivoted is completely free, the locking projection 83 is erected at the eccentric position of the disc 81 pivoted on the end of the support shaft 49. It stops by rotating by the pulling spring locked at the upper end. And
When the movement of the switch 69 in the rightward direction shown in the sixth illustration is released, the elastic protrusion 69d elastically returns to the left and returns to the central portion. At this time, the gear 59, the gear 65 and the second cam
The cam protrusion 57 and the pin 45a of the second lever 45 are engaged with each other.

As shown in FIGS. 4 and 5, the push button 51 has a conductive contact piece 15 attached to its side surface. The conductive contact piece 15 is provided with a notch 15a bent in a V shape. Further, a conductive contact piece 13 that can contact the conductive contact piece 15 is attached to the head 3. The conductive contact piece 13 has a cut portion of the conductive contact piece 15.
The projection 13a that fits into the 15a is projected, and the conductive contact piece 1
5, 13 are configured so that the circuit is closed when the projection 13a is fitted into the cut portion 15a. Then, when the push button 5 is pressed to fit the protrusion 13a into the notch 15a, the second motor 119 is driven, and the support shaft 49 rotates together with the gear 59 via a predetermined transmission gear. A notch is formed on the outer periphery of a conductive plate 79 axially attached to the end of the support shaft 49, and the conductive plate 79 is rotated by a pulling spring 85 when the switch 69 is opened, and a conductive contact piece.
77 is positioned in the notch of the conductive plate 79 and is stopped in a state of being separated from the conductive plate 79. Rotation of spindle 49 causes conductive plate
79 also rotates, and the tip of the conductive contact piece 77 comes out of the notch of the conductive plate 79 and engages with the outer peripheral edge. Further, the eye 11 fitted to the tip of the swing lever 17 by the head 3 which is largely moved up by the second lever 45 engaged with the second cam 57 is rotated clockwise in the fifth illustration, and the eye 11 is rotated. A rotating piece 11b axially attached to the end of the support shaft 6 of 11 and 11 contacts the step portion 5a of the push button 5 from below to move the push button upward. Notch 15a of the electrically conductive contact piece 15 of the pushed push button 5
Disengages the protrusion 13a of the other conductive contact piece 13 and separates it. The rotary switch 78 is operated by operating the push button 5, and the wake-up operation is performed until the rotary switch 78 is automatically opened. The wake-up operation is not related to the alarm time of the timepiece movement 9. It is prepared to confirm.
