PURPOSE:To form a slide plate guiding device of low cost and of high reliability, in a mechanism wherein, by providing a motion transmitting device between the first and the second guide plates, the second guide plate makes reciprocal movements in accordance with the movement of the first guide plate. CONSTITUTION:Internal gear 29 is installed concentrically with the bearing 27 which rockably supports the guide plate 1 of the first slide plate, and the pinion 30 being supported by the guide plate 1 is geared with the internal gear 29. Then, the driving force is transmitted to the sprocket 33 of the intermediate shaft 32 from the sprocket 31 which is concentric with the pinion 30, followed by the driving of the chain 39 being disposed between the sprocket 31 of the shaft 32 and the sprocket 38 of the shaft 37. The second guide plate 7A being connected with the chain 39 starts reciprocal motion by the movement of the guide plate 1. This is; the circular movement of the first guide plate 1 with bearing 27 as its concentric center as shown by the arrow in full line makes the second guide plate 7A being housed within the first guide plate proceed forward as shown by the arrow in full line, sliding thru the strip. In the case of the reverse motion, movement of each piece concerned is as shown in arrows in dotted line. |
