Claims

[Scope of utility model registration request]

(1) A conveyance device in which a thrust applying means is arranged along a conveyance path on which a conveyed object travels, and the thrust applying means applies a reverse propulsive force to the conveyed object traveling due to inertia to decelerate it, the thrust applying means 1. A conveyance device comprising: a control means for controlling the supply of drive energy for driving to generate a propulsive force so that it gradually decreases from the start of deceleration to the end of deceleration.

(2) The conveyance device according to claim 1, wherein the control means controls supply so that the frequency of current change supplied to the thrust applying means is gradually lowered.

(3) The conveyance device according to claim 1, wherein the control means controls the current supplied to the thrust applying means so as to gradually decrease the current value.

(4) The conveyance device according to claim 1, wherein the control means gradually decreases the voltage value supplied to the thrust applying means.
