An assembling device for supplying and assembling a part on an object has a table and a first moving portion disposed above the table, where the first moving portion includes a guide and a movable body. The guide extends in a first direction parallel to a surface of the table out of a range in which the table is positioned. The movable body is movable to a position out of the range in which the table is positioned. The assembling device also has a second moving portion disposed on the table and movable in a second direction transverse to the first direction, the object being mounted on the second moving portion.

A position control system for controlling a motor-driven mechanism capable of occupying a plurality of specified positions comprises a plurality of switches for specifying a position to be occupied by the mechanism and an encoder for generating a specified position signal representative of the specified position and a loading circuit for providing a present position signal representative of the position presently occupied by the mechanism. A read-only memory circuit uses the specified and present position signals to provide a control signal for controlling the motor to move the mechanism to a particular position and a comparison signal and a particular position signal indicative of that particular position. A position detector responsive to the position of the mechanism provides a detection signal representative of the particular position when the mechanism reaches it. A comparator compares the comparison signal from the memory circuit with the detection signal and provides a match signal to the loading circuit when they coincide. In response to the match signal the loading circuit loads the particular position signal into the memory circuit as the present position signal. If the particular position signal matches the specified position signal, the memory circuit provides a control signal that stops the motor. If the particular position does not match the specified position signal, the memory circuit provides a control signal to actuate the motor again. The illustrated embodiment of the system provides a tape recording and reproducing apparatus with four different operating modes.
