[0010]
The driving wheel 11 is intermittently hollowed in the center of a thin cylindrical peripheral wall in the circumferential direction, and the circular belt-shaped end portions 12 and 12 existing on both sides in the axial direction (bandwidth direction) are hollowed out. The remaining plurality of stays 13 are connected to each other in a cage shape. A power transmission portion 14 is provided on the outer peripheral surface side of the end portion 12. The recess 15 of the power transmission unit 14 is recessed from the outer peripheral surface of the end 12 to the inside, and the outer side in the axial direction of the recess 15 is open. The convex part 16 of the power transmission part 14 is formed by the slopes of the two concave parts 15 adjacent to each other in the circumferential direction and the outer peripheral surface of the end part 12 between the two concave parts 15. A hub 17 is coupled to the plurality of stays 13 by the support member 3 at a position that is offset to one side from the center between the end portions 12 and 12. A central portion of the hub 17 is provided with a motor output shaft mounting portion 18 formed in an oval shaped irregular hole.
A plurality of convex portions 16 as driving wheel side engaging portions that engage with the concave portions 6 as the symbol display body side engaging portions are provided on both axial ends of the driving wheel 11, that is, on the outer peripheral surfaces of the end portions 12 and 12. The recesses 15 are provided at equal intervals in the circumferential direction, and the interval between the adjacent protrusions 16 and 16 is made wider than the interval between the adjacent recesses 6 and 6. That is, each convex part 16 as a plurality of driving wheel side engaging parts is intermittently engaged with each concave part 6 as a plurality of symbol display body side engaging parts provided at equal intervals. Therefore, the number of concave and convex engagements between the driving wheel 11 and the symbol display body 2 can be reduced, and the engagement friction between the concave and convex portions can be reduced, so that the rotational load of the motor can be reduced and output as a motor for driving the driving wheel 11. A small motor can be used.

The driven wheel 21 is intermittently hollowed in the center of a thin cylindrical peripheral wall in the circumferential direction and has circular band-shaped end portions 22, 22 existing on both sides in the axial direction (band width direction). A plurality of remaining stays 23 are connected to each other to form a cage. However, the driven wheel 21 has a configuration in which the outer peripheral surface of each of the end portions 22 and 22 does not include the convex portion and the concave portion that engage with the concave portion 6 and the convex portion 7 as the symbol display body side engaging portion. That is, each end 22 has a large ring portion 24 on the inner side in the axial direction, and on the outer side in the axial direction of the large ring portion 24, the inner surfaces on both sides in the width direction of the symbol display body 2 having a slightly smaller diameter than the large ring portion 24. The symbol display body side engaging part formed on 2a has a corresponding small ring part 25, and the outer peripheral surface of the round-shaped small ring part 25 centered on the rotation center of the driven wheel 21 is a flat circumferential surface. Is formed. Therefore, when the symbol display body 2 is rotated by the driving force of the driving wheel 11, the contact between the inner side surface 2a of the symbol display body 2 and the outer peripheral surface of the large ring portion 24 of the driven wheel 21 or the convexity of the inner side surface 2a of the symbol display body 2 is achieved. The driven wheel 21 is also rotated by the contact between the portion 7 and the outer peripheral surface of the small wheel portion 25. At this time, however, the engagement friction due to the uneven engagement does not occur, so the rotational load of the motor can be reduced and the driving wheel 11 is driven. As a motor to be used, a motor with a small output can be used. The bearing portion 27 of the driven wheel 21 to which the support shaft 82 is attached is supported by a support member 3B connected to the stay 23.

The step motor 31 is a double-axis type in which motor shafts 32 and 33 protrude from both ends of the motor body 34 in the axial direction. One motor shaft 32 (motor output shaft) has an outer peripheral surface with two flat and parallel notched surfaces 32a, and the motor output shaft is mounted from the direction of the end 12 away from the hub 17 of the drive wheel 11. Inserted into the portion 18 and mounted on the hub 17 so as to rotate together, the drive wheel 11 is coupled to one motor shaft 32 so as to rotate together.
[0013]
When the drive wheel 11 and the one motor shaft 32 are coupled in this way, most of the motor body 34 is taken into the drive wheel 11 in a non-contact state. The other motor shaft 33 protruding toward the bracket 37 provided at the end of the motor body 34 is inserted into an escape hole 42 formed in the motor attachment piece 41, and the bracket 37 is attached to the motor attachment piece 41 around the escape hole 42. The motor body 34 and the motor mounting piece 41 are coupled to each other by the bracket 37 and the motor mounting piece 41 being fastened to each other by a set screw (not shown).
[0014]
The other motor shaft 33 is an irregular shape having one flat notch surface on the outer peripheral surface, and the other motor shaft 33 is inserted into a semicircular irregular mounting hole 52 formed at the center of the small-diameter gear 51. A small gear 51 is mounted on the other motor shaft 33 so as to rotate together. A shaft 43 fixedly mounted around the escape hole 42 of the motor mounting piece 41 is rotatably mounted with a large-diameter gear 61 that meshes with the small-diameter gear 51 and protrudes outward from the large-diameter gear 61. A retaining ring (not shown) is attached to the shaft 43 so that the large-diameter gear 61 is prevented from coming off the shaft 43.
[0015]
A detected object 62 for detecting the origin position of the step motor 31 is attached to the large-diameter gear 61 so as to rotate together with a set screw (not shown). A substrate 64 provided with a detector 63 for detecting the origin position of the step motor 31 is attached to a motor mounting piece 41 around a notch 44 formed below the shaft 43 with a set screw (not shown). Thus, the detector 63 is disposed in a non-contact manner on the notch 44. Each time the detected object 62 passes through the detector 63 in a non-contact manner through the small-diameter gear 51 and the large-diameter gear 61 as the other motor shaft 33 rotates, the detector 63 performs a step. A detection signal as the origin position of the motor 31 is output to a control device (not shown).
[0016]
The motor mounting piece 41 in which the drive wheel 11, the step motor 31, the small diameter gear 51, the large diameter gear 61, the shaft 43, the substrate 64, the detector 63, and the detected body 62 are combined is a plate-like shape as a vertically long base. The motor attachment piece 41 closes the opening 72 formed in the upper part of the mechanism main body 71 by being attached to the upper part of the mechanism main body 71 with a set screw (not shown). The motor mounting piece 41 is formed with a wiring hole 73 for passing the wiring extending from the detector 63 so as to be positioned around the opening 72.
The bearing portion 27 of the driven wheel 21 is inserted into a support shaft 82 fixedly provided on the driven wheel mounting base 81, and a retaining ring (not shown) is attached to the end of the support shaft 82 protruding from the bearing portion 27. The driven wheel 21 is prevented from coming off from the support shaft 82.
[0018]
The driven wheel mounting base 81 includes a shaft 83, a reference shaft portion 84A (swing center shaft), two sliders 84 and 84 (swing guide shaft), and a spring mooring portion 85 (base side spring mooring portion). The shaft 83 is inserted into an arc-shaped escape hole 76 formed in a driven-wheel mounting portion 70 formed so as to bulge in the direction of the driven wheel 21 at the lower part of the mechanism body 71 and can move in the arc-shaped escape hole 76. It has become. After the reference shaft portion 84A is inserted into the bearing hole 74A formed in the driven wheel attachment portion 70, a stopper 86A is attached to the reference shaft portion 84A to prevent the reference shaft portion 84A from passing through the bearing hole 74A. It is mounted rotatably. After the sliders 84 and 84 are inserted into the arc-shaped escape holes 74 (swing guide holes) formed in the driven wheel mounting portion 70, a stopper 86 is attached to the slider 84 to prevent the sliders 84 and 84 from being removed. Sliding movement is possible in the arc-shaped escape hole 74. The spring mooring portion 85 is inserted into an arc-shaped escape hole 75 (swing guide hole) formed in the driven wheel mounting portion 70 and can move in the arc-shaped escape hole 75. The arc-shaped escape holes 74 , 75, 76 are formed in an arc shape centered on the bearing hole 74A of the reference shaft portion 84A. Thus, the driven wheel mounting base 81 and the driven wheel mounting portion 70 that rotatably support the driven wheel 21 are assembled to each other.
[0019]
A spring 78 such as a coil spring is latched to a spring mooring portion 85 of the driven wheel mounting base 81 and a spring mooring portion 77 (mechanism main body side spring mooring portion) provided in the driven wheel mounting portion 70. The spring 78 pulls the driven wheel mounting base 81 in the direction of increasing the axial distance from the driving wheel 11 mounted on the upper part of the mechanism main body 71, so that the symbol display body 2 is wound around the driving wheel 11 and the driven wheel 21. It is done. That is, a spring force in a direction in which the driven wheel 21 stretches the symbol display body 2 is applied to the driven wheel mounting base 81 by the spring 78.
[0020]
When the step motor 31 is driven to rotate by power supply, the symbol display body 2 is engaged with the power transmission portion 5 of the symbol display body 2 and the power transmission portion 14 of the drive wheel 11 while receiving tension from the spring force of the spring 78. Rotate properly. During rotation, even if an excessive force is applied to the driven wheel 21, the sliders 84, 84, the spring mooring portion 85, and the shaft 83 move about the reference shaft portion 84 </ b> A through the arc-shaped escape holes 74, 75, 76. Since the driven wheel mounting base 81 can swing in the vertical direction, the symbol display body 2 can be rotated while always applying an appropriate tension to the symbol display body 2 by the spring 78, so that the symbol display body 2 can be stabilized. Can be rotated.
[0021]
If a person operates to move the spring mooring portion 85 upward against the spring 78, the driven wheel mounting base 81 moves upward and the distance between the drive wheel 11 and the driven wheel 21 becomes narrower. The body 2 can be easily removed from the driving wheel 11 and the driven wheel 21. That is, the symbol display body 2 is easily attached to and detached from the drive wheel 11 and the driven wheel 21 by operating the spring mooring portion 85 in the direction of narrowing the distance between the driven wheel 21 and the driving wheel 11. it can. Therefore, when the symbol display body 2 is attached, the work at the time of replacement becomes easy.
[0022]
The driven wheel mounting base 81 is formed in a triangular shape, and a reference shaft portion 84A is provided at one corner of the triangle, and sliders 84 and 84 are provided separately at two other corners of the triangle. It has been. That is, the two sliders 84 and 84 are provided apart from each other in the vertical direction. As described above, since the two sliders 84 and 84 are provided apart from each other in the vertical direction, the vertical movement of the driven wheel mounting base 81 with respect to the mechanism main body 71 by the sliders 84 and 84 is ensured, and the sliders 84 and 84 are the stoppers. Since it is stopped at 86, the rattling of the driven wheel mounting base 81 in the left-right direction can be reduced, and the symbol display body 2 can be rotated stably. Further, since the driven wheel mounting base 81 is formed in a triangular shape, the weight can be reduced as compared with a circular shape or a rectangular shape, and the symbol display body 2 can be stably rotated. Further, since the two sliders 84 and 84 are individually provided at the two corners of the triangular shape, the distance between the two sliders 84 and 84 is maximized, and the reliability of the vertical movement and the right and left of the driven wheel mounting base 81 are increased. The effect of preventing the backlash of the direction can be further improved, and the symbol display body 2 can be rotated more stably.
