Abstract:
1. A mounting apparatus comprising: an electronic component feeding unit for feeding a electronic components; a board holding section for holding a circuit board, onto which the electronic components are to be mounted, and being capable of moving the circuit board in two orthogonal directions along a mounting surface; a mounting section for mounting the electronic components, fed from said electronic component feeding unit, onto the circuit board when held by said board holding section; drive units for driving said electronic component feeding unit, said board holding section, and said mounting section, respectively; an effective torque detecting section for detecting an effective torque required by at least one of said drive units at an effective-torque detection cycle; an effective torque deciding section for deciding whether or not the effective torque as detected by said effective torque detecting section has exceeded an upper-limit value, or whether or not the effective torque as detected by said effective torque detecting section has been restored from an excess value to a safety value; a detection error eliminating means for deciding whether or not the effective torque as detected by said effective torque detecting section is a detection error, before a decision is made by said effective torque deciding section to assign the effective torque, after having been decided by said error eliminating means to be a non-detection error, to an object for a decision to be made by said effective torque deciding section; and a control section for performing control of said electronic component feeding unit, said board holding section, said mounting section, said drive units, said effective torque detecting section, said effective torque deciding section, and said detection error eliminating means, such that
