摘要:
The invention provides an electronic component mounting apparatus in which a mounting time per electronic component can be reduced by starting a vertical movement motor and so on as early as possible. When a CPU judges that an interlock canceling condition where the movement of a suction nozzle in X and Y directions is to be completed is satisfied and judges that an interlock canceling condition where an electronic component is to be fed on an electronic component feeding unit is satisfied, the CPU outputs a signal indicating the satisfaction of the canceling conditions to a second motor controller. A CPU of the second motor controller that receives the signal indicating the satisfaction of the interlock canceling conditions about the movement of the suction nozzle in the X and Y directions and the feeding of the electronic component on the electronic component feeding unit immediately outputs a start signal to a nozzle vertical movement motor.

In the color image transmission system between a pair of computer image processing systems A & B, a common basic color such as R.G.B. basic color is firstly decided, then this common basic color is transmitted from the system A to the system B so that a digital image (X) is indicated on the monitor of the system B, the color matching operation is applied to the digital image (X) to substantially match the displayed color thereof and decide a correction value a from color data indicated on the monitor of the system B. This correction value α is used in a color calibration process applied to a digital image (Y) indicated on the monitor of the system B which is created by transmitting an original color image (Y0) from the system A so that a color modified digital image (Z) having a color substantially matched to the color of the original color image (Y0) is indicated on the monitor of the system B.

The invention is directed to quick adjustment of a positional relationship between two axes when an error occurs in the positional relationship between the axes when a beam is moved by two drive sources. According to movement of the beam for component picking and mounting operations, linear scale signals (outputs relating to positions of one drive axis and another drive axes) from linear scale reading heads are inputted to a Y2 driver and a Y1 driver respectively. Since each of the Y2 driver and the Y1 driver has a calculation means and a control means, when inputted with both the linear scale signals, each of the Y2 driver and the Y1 driver calculates a difference between positions of the drive axes of the beam by the calculation means, and controls a moving member of a linear motor by the control means based on the difference so as to increase thrust of one drive axis in a case where the one drive axis is in a more backward position than another drive axis and reduces the thrust of one drive axis in a case where the one drive axis in a more forward position than another drive axis.

Bearing pieces are formed on both sides of the rear end of a clincher arm which includes a clincher table for bending a staple at the front end thereof. A magazine member to which staples are loaded and a driver arm for driving out a staple fed from the magazine member are pivotally mounted on an axle, which is provided at the rear ends of the bearing pieces. A handle member is rotatably disposed above the driver arm. A rotation supporting shaft of the handle member is provided at a position somewhat closer to the front than the axle of the bearing pieces. A pin, which is provided at a position closer to the front than the rotation supporting shaft of the handle member, is inserted into an elongated hole formed in each side plate of the driver arm.

The image surface of an original photograph is covered with a transparent plastic film and the image is corrected by painting on the transparent film so that a combined image material is made. Then this combined image material is digitized with scanning equipment and the resulting digital data is stored in a computer. Thereafter, conventional computer image processing technology is applied to modify the digital image displayed on the monitor of the computer.

A frequency multiplier circuit device having a delay circuit including a plurality of delay elements, and a selector circuit for selecting the number of delay elements for every output stage of the delay circuit. A reference input signal and an output from the selector circuit for determining the period of the reference input signal are input to a phase comparator. The selector circuit is controlled on the basis of an output from the phase comparator to select the number of delay elements of the delay circuit, so as to generate a signal for multiplying a frequency by N, so that the signal is supplied to an exclusive NOR circuit to output a signal having a frequency an N-number of times that of the reference input signal.

An electronic still camera includes a picture signal processing circuit and a compression processing circuit. A photographed picture signal is subject to compression processing in the compressing processing circuit after being processed in the picture signal processing circuit. Electric power supply from a power source circuit is controlled by a control circuit. Electric power is supplied only to the picture signal processing circuit at the time of picture processing, while electric power is supplied only to the compression processing circuit at the time of compression processing. In this way, electric power supply is controlled, resulting in savings of electric consumption and improving the picture quality.

An image distortion correcting apparatus for a television camera. In addition to an analogue correcting waveform, four corner independent distortion correcting waveforms are employed for rough adjustment together with a digital distortion correcting signal serving for fine adjustment. These waveforms are combined to be utilized for correcting image distortion from which the television camera suffers. A high-accuracy correction of image distortion can be accomplished with a circuit configuration of a small scale.
