As shown in FIG. 3, first restriction grooves 30, 30 in the left-right direction for guiding the traveling of the first divided door 1, 1 and second restriction for guiding the traveling of the second divided door 2, 2. Grooves 40, 40 are provided. The first regulating grooves 30, 30 are provided at the front of the case 100, similarly to the grooves that are guided when a normal door opens and closes in the left-right direction.
[0012]
The second regulating grooves 40, 40 are formed in a curved shape, and the curved state is formed in a direction away from the first regulating groove. In the present example, the first regulating grooves 30, 30 and the second regulating grooves 40, 40 are symmetrically provided above and below the divided door.
[0013]
The split doors 1 and 2 are provided on the back surfaces of the ends adjacent to each other so as to be fixedly connected to a hinge-shaped connecting tool 50 so as to be rotatable.
[0014]
Further, the first divided door 1, 1 includes an engaging portion that engages with the first regulating groove 30, 30, and the second divided door engages with the second regulating groove 40, 40. The engaging portion is provided. In this example, the first regulating grooves 30 and 30 and the second regulating grooves 40 and 40 provided above the opening constitute a so-called guide rail for suspending each of the divided doors. The upper engaging portions of the divided doors 1 and 1 and the divided doors 2 and 2 are constituted by rotating suspension bodies 1a and 2a that engage with the guide rails.
[0015]
On the other hand, the first restricting grooves 30, 30 and the second restricting grooves 40, 40 provided in the lower part of the opening are formed in the horizontal plate of the opening. The lower engaging portions of the doors 2 and 2 are formed by protrusions 1b and 2b that engage with the grooves.
[0016]
In the case of the present example, the drive device 20 for driving the split door, which opens and closes the split door by a motor, a rack and a pinion, as shown in FIG. 1, is housed below the case. The motor 21 is installed at substantially the center below the horizontal plate, and a pinion 23 is provided above the motor 21 via wheel trains 22 and 22. In front of and behind the pinion 23, racks 24, 25 which are long in the left-right direction are arranged so as to sandwich the pinion 23, and one of the racks 24 is provided with a fixing member 24a, which is a projection of a split door on the right side in the figure. 1b, and the other rack 25 is linked to the projection 1b of the split door on the left side in the figure via a fixture 25a.

[0018]
When the divided doors 1, 1 start to move, the divided doors 1, 1 move left and right with their engaging portions (the rotary suspension bodies 1a and the protruding bodies 1b) being regulated by the first regulating grooves 30, 30. On the other hand, the engaging portions (the rotary suspension 2a and the protruding body 2b) of the second divided doors 2, 2 are regulated by the second regulating grooves 40, 40, and the second divided doors 2, 2 are pivoted about the connecting members 50, 50. Start. Further, as the division doors 1, 1 and the division doors 2, 2 move, the division doors 2, 2 rotate, and as shown by a broken line in FIG. The doors 2, 2 are provided at right angles to the first divided door 1, 1. Therefore, compared to a case where the divided doors 2 and 2 are simply opened and closed, the storage interval in the left-right direction can be smaller.
[0019]
Next, a pair of divided dials disposed behind the divided doors 1 and 2 will be described. As shown in FIG. 4, a dial 6 having a flat front surface is provided in the concave portion 2a of the case, and a numerical index is provided on the front surface of the dial 6 on the circumference. I have. The dial 6 is divided into a plurality of divided dials 3, 4, and 5 by vertical straight lines that connect the opposite sides, and upper and lower ends of the divided dials 3, 4, and 5 are formed by a case. It is pivotally supported on the 60 side. That is, the dial 6 is formed in a long plate shape, and has a first divided dial 3 in which the clock shaft 10 is positioned at the center, and left and right sides of the first divided dial 3 are narrower than the first divided dial 3. It is composed of a second divided dial plate 4 and a third divided dial plate 5 set to the same left and right width as the first divided dial plate 3.
[0020]
As shown in FIG. 5, a stage for mounting a decorative body 7a such as a doll of the mechanism device 7 is provided on the back surface of the first, second, and third divided dials 3, 4, and 5 thus divided. The decorative body 7a is provided to perform a predetermined mechanism operation by a built-in motor, and the operation of the motor is controlled by a control circuit.
[0021]
As shown in FIG. 6, rotating shafts 3a, 4a, 5a extending in the vertical direction are fixed to upper and lower ends of the middle of these divided dials 3, 4, 5, respectively. The rotation shafts 4a and 5a are rotatably supported on the case side, and the upper rotation shafts 3a, 4a and 5a are connected to the reversing gear mechanism 8. The reversing gear mechanism 8 includes driving gears 13, 14, 15 fixed to the rotating shafts 3a, 4a, 5a of the divided dials 3, 4, 5 for driving the divided dials 3, 4, 5 in reverse. And an intermediate gear 8a provided therebetween. The same gears are used as these gears, and each of the divided dials 3, 4, and 5 is driven to rotate in the same direction and at the same rotational speed when the dial is inverted. The reversing gear mechanism 8 is connected to a drive motor 8b that can rotate forward and reverse, and the drive motor 8b is connected to a control circuit, and the control circuit controls the forward and reverse rotation of the drive motor 8b as required. I have. Reference numeral 18 denotes a stopper member for preventing the third divided dial 5 on the right side in the figure from over-rotating, and is formed in a square rod shape and fixed to the edge of the concave portion of the case.
[0022]
Further, as shown in FIG. 7, the pivotal positions of the divided dials 3, 4, and 5 are set eccentrically on the rear side of the mechanical timepiece 100. That is, as shown in FIG. 8, the rotating shaft 3a holding the first divided dial 3 is moved to the rear side by the distance L, and the outer edge of the first divided dial 3 drawn around the rotating shaft 3a. The trajectory A1 has moved toward the back of the watch as indicated by the dashed line, compared to the outer edge trajectory B1 when the rotation axis 3c is provided at the center of the first divided dial 3 indicated by a virtual line in the figure. It becomes a trajectory. As a result, when the first divided dial 3 is inverted, the amount of projection from the dial surface in the normal time display state toward the front of the watch decreases from B2 to A2 in FIG. By eccentricizing the rotation axis of the dial in this way, even when the outer edge trajectories of the adjacent divided dials overlap each other, they are inverted at the same rotational speed in the same direction without interfering with each other. An inversion operation can be performed.
[0023]
The clock shaft 9 is composed of an hour hand shaft, not shown, and a cylindrical minute hand shaft surrounding the outer periphery of the hour hand shaft. The clock shaft 9 is located at the center of the index of the dial 6, that is, It is disposed substantially at the center of the one-piece dial 3. The hour hand axis / minute hand axis of the clock shaft 9 penetrates through the dial 3 from the liac movement 11 fixed to the back of the first divided dial, and projects forward from the front. The minute hand 10a and the hour hand 10b of the clock hand 10 are mounted. The timepiece shaft 9 is driven to rotate in a predetermined manner by the liac movement 11, and drives the hour hand 10b and the minute hand 10a to display the current time.
[0024]
The liak movement 11 houses an hour hand driving pulse motor and a minute hand driving pulse motor that individually drive the hour hand 10b and the minute hand 10a, not shown. These pulse motors are controlled by a control circuit. Driving is controlled by a pulse signal. That is, the pulse motor for driving the minute hand of the liac movement 11 is decelerated by a train of wheels configured to rotate the minute hand shaft by one degree when the pulse is rotated 180 degrees by inputting one pulse. The pulse motor for use is decelerated by a train of wheels such that the hour hand shaft rotates only once when it is rotated 180 degrees by input of one pulse. Therefore, by counting the number of pulses output to each pulse motor, it is possible to perform drive control while reliably grasping the display position of each hand, and control each pulse motor by the control circuit to control each time during the mechanism operation. When the divided dials 3, 4, and 5 are inverted, the hour hand 10b and the minute hand 10a are temporarily moved on the third divided dial 5, retracted, and returned.
[0025]
In addition, the liac movement 11 can be moved from the retracted state to the current time display position to return to the normal time display.
The specific configuration of such a liac movement 11 is disclosed in Japanese Patent Application Laid-Open No. 5-93784 or Japanese Patent Application Laid-Open No. 8-129907, and will not be described.
[0026]
Next, a control (not shown) for controlling the operation of the mechanism 7a of the decorative body 7a, the dial 6 (divided dials 3, 4, 5), and the pair of divided doors 1 and 2 in accordance with a predetermined procedure. The circuit will be described with reference to FIG.
[0027]
At a time other than the hour or when the monitor switch is not pressed, as shown in FIG. 1, the mechanism clock 100 has the door 6 open, and the divided doors 1 and 2 of the door 6 are stored inside the case 60. The divided dials 3, 4, and 5 disposed behind the door 6 face the dial face toward the front of the watch. That is, in a normal state (when the time zone or the monitor switch is not pressed), the current time can be recognized from the front side of the watch.
[0028]
When a normal time signal or a monitor switch signal is input by pressing the monitor switch from a normal state to a control circuit (not shown), the divided dials 3, 4, and 5 become invisible from the front side of the timepiece as shown in FIG. Thus, the door 6 is closed so as to cover the recess 2a. Therefore, since the divided doors 1 and 2 housed in the case appear on the front side of the watch, the picture drawn on the surface of the divided doors 1 and 2 can be seen (procedure 1).
[0029]
After the divided doors 1 and 2 have finished appearing on the front side of the timepiece, the hour hand driving pulse motor and the minute hand driving pulse motor are driven to temporarily move the hour hand 10b and the minute hand 10a onto the first divided dial 3. Move and retreat (procedure 2). At this time, since the divided doors 1 and 2 are closed, the evacuation state cannot be seen from the front of the watch.
[0030]
After the hour hand 10b and the minute hand 10a are temporarily moved and retracted on the first divided dial 3, as shown in FIG. 7, the reversing gear mechanism 8 is driven to move the divided dials 3, 4, 5 The decorative body 7a is turned upside down to appear on the front side of the watch (step 3). Since the divided doors 1 and 2 are closed at this time, the appearance of the decorative body 7a cannot be seen from the front of the watch.
[0031]
After the decorative body 7a appears, the door 6 is opened and the divided doors 1 and 2 are stored in the case 60 (procedure 4). At this time, the decorative body 7a can be seen from the front side of the timepiece. In addition, since the viewer does not show the movement of the divided dial, the scene is greatly changed when the door 6 is opened, and it is possible to give surprise and surprise as if watching the stage. .
[0032]
After the door 6 is opened, the built-in motor (not shown) of the mechanism 7 is driven to perform the mechanism operation on the decorative body 7a (step 5).
[0033]
After finishing the mechanism, the door 6 is closed again (procedure 6).
[0034]
After closing the door 6 again, as shown in FIG. 7, the reversing gear mechanism 8 is driven to reverse the divided dials 3, 4, and 5, so that the dial face appears on the front side of the timepiece (step 7). At this time, since the division doors 1 and 2 are closed, the appearance of the dial surface cannot be seen from the front side of the watch.
[0035]
After the dial surface appears, the hour hand driving pulse motor and minute hand driving pulse motor are driven to return the hour hand 10b and the minute hand 10a to the current time. (Procedure 8). At this time, since the divided doors 1 and 2 are closed, the state of returning cannot be seen from the front of the watch.
[0036]
After returning the hour hand 10b and the minute hand 10a, the division doors 1 and 2 are opened again (procedure 9). At this time, the dial faces of the divided dials 3, 4, and 5 can be seen from the front side of the timepiece. In addition, since the person who is watching does not show the movement of the divided dial, it is not possible to realize what kind of mechanism caused the divided dial to appear, and it is possible to provide scene change, surprise and unexpectedness Can be given. In the state shown in FIG. 1, the operation waits until the next hour signal is input or the monitor switch signal is input. Since the door 6 is open while waiting, the time can be recognized.
[0037]
In this specific example, the clock hand 10 is retracted / returned by a motor that can rotate forward and backward so that the operation can be performed more quickly. However, the clock hand 10 has a clock counter that stores the time and a pointer position counter that stores the position of the clock hand. With the configuration, the evacuation / return is possible without using a separate motor and a motor that can rotate forward and backward.
[0038]
According to this specific example, when the divided dial is inverted, the door disposed in front of the divided dial is closed, so that when the divided dial is inverted, a driving device or the like on the back of the dial is used. Cannot be seen from the front of the watch. Therefore, this door makes it impossible to both visually recognize the reversing operation of the divided dial and to visually recognize the driving device and the like located behind the dial accompanying the operation.
[0039]
According to this specific example, the door 6 is divided doors 1 and 2 that slide left and right. However, instead of a structure that slides right and left, for example, using an opening and closing door mechanism disclosed in Japanese Patent Application Laid-Open No. 4-259889, When the opening and closing door is open, a state where flowers are blooming may be expressed, and when the opening and closing door is closed, a state where the flowers are closed may be expressed. In addition, the door 6 does not need to be a divided door, and the door 6 may be a single plate. Furthermore, in this specific example, the decorative body 7a appears on the front side of the timepiece by inverting the divided dials 3, 4, and 5 as the moving dial, but this is disclosed in JP-A-8-68870. A structure may be used in which a decorative body arranged on the back side of the divided dial appears by moving the divided dial up and down or left and right. It is not necessary to divide the divided dials 3, 4, and 5, and the dials may be made movable as one dial.
[0040]
