Claims (2)

[Scope of utility model registration request] (1) A driving device that drives a driven member, a data generating means that generates moving distance data representing a distance to move the driven member, and supplying a high-speed drive signal to the driving device based on the moving distance data. and drive signal generating means for supplying a low-speed drive signal immediately before the driven member stops, and moving the driven member to a positioning location separated by a distance represented by the movement distance data. The control device includes a movement distance detection means for detecting an actual movement position of the driven member, and a deceleration distance in which a first deceleration distance and a second deceleration distance shorter than the first deceleration distance are respectively stored in advance. a storage means; prior to driving the driven member, the moving distance represented by the moving distance data is compared with a predetermined fixed moving distance, and the moving distance represented by the moving distance data is determined to be the fixed moving distance. mode determining means for determining a long-distance deceleration mode when the value is larger than , and determining a short-distance deceleration mode when the value is smaller than the above-described mode; , when the moving position of the driven member reaches a position before the positioning location by the first deceleration distance, the content of the high-speed drive signal is a low-speed drive that makes the speed of the driven member slower than before. On the other hand, if the mode determining means determines that the mode is short-distance deceleration mode, when the moving position of the driven member reaches a position before the positioning location by the second deceleration distance, A drive control device for a positioning device, comprising: deceleration control means for switching the content of a drive signal to the low-speed drive signal. (2) Utility model registration according to claim 1, wherein the predetermined travel distance is the first deceleration distance, and the second deceleration distance is 172 of the travel distance represented by the travel distance data. Drive control device for positioning device.
