A visual presentation apparatus which applies an illuminating light to an object placed on a stand, obtains an image of the illuminated object using a pick-up camera, transmits the image to a display whereat the image is displayed; wherein the front, back, left and right sides of the stand are open by using a flat plate as the stand, and by mounting the light source on an arm which also supports the pick-up camera and placing the arm outside the stand; and wherein the pick-up camera comprises a mechanism rotatable around the horizontal and vertical axes; and wherein sample clocks which are synchronized with color burst signals are generated by the apparatus and frame memories in which the images are stored are switched at the time of the sample clocks.

Visual presentation equipment

A motor drive system used with industrial robots, processing machines, and the like comprising an external interface part ready for connecting a plurality of kinds of host controllers generating a command signal; a sensor interface part to which a motor rotation detecting sensor is connected; a main control part operating for feedback control of a motor according to signals provided by way of the interfaces; and a power amplification part for feeding a current to motor coils according to a control signal from the main control part and wherein the external interface part, the sensor interface part, the main control part, and the power amplification part are separate and modularized as cards. Advantageously, the various controllers, sensors and power systems are changeable to flexibly meet different user requirements.
