<p>PURPOSE:To make a driven part operatable in a direction different from the direction of motion in a driving gear as well as to aim at simplification and miniaturization in a device, by installing a pin in a connecting part of the driving gear, while installing a long hole in this connecting part of the driven part in the direction crossed with its direction of motion. CONSTITUTION:An arm 3 is rotatably attached to a driving gear 1 via a gearbox 2, and a pin 4 is installed in a tip end of the arm 3 vertically with a rotational surface of the arm 3. And, at a driven part 6 having a direction indicating surface 5, there is provided with a connecting part 8 installing a long hole 7 formed long in a vertical direction to the direction indicating surface 5, while the pin 4 is inserted into the long hole 7, and the driving gear 1 and the driven part 6 are combined together. With this constitution, rotational motion of the driving gear 1 is convertible to rectilinear interlocking motion of the driven part 6 without using the intermediation of a special link rod, therefore the number of parts items is well reducible, thus its structure becomes simplified and miniaturization in the device attainable.</p> |
