摘要:
Disclosed are an apparatus and a method for bonding electronic components, a circuit board, and an electronic component mounting apparatus, whereby various kinds of circuit boards can be manufactured, each by a small amount, with high productivity as compared with the conventional art. There are provided a stage member and a heating device, so that a circuit board is heated by the heating device while held in contact with the stage member, which stage member has a size almost equal to that of one circuit board. Generation of losses can be reduced for compact circuit boards, and heating can be performed individually, correspondingly, for each kind of circuit board. Manufacturing various kinds of circuit boards, each by a small amount, with high productivity as compared with the conventional art is enabled accordingly.

A video game machine has a mechanism extracting balls, a display unit having a display area which displays a matrix composed of boxes, and a CPU. The CPU implements a function enabling the player to appoint a ball type in terms of color and number to boxes of a second line of the matrix. A function is provided for automatically displaying, in the first and third lines of the matrix, ball marks correlated to the ball marks displayed in the second line, such that the color sequences of the ball marks in the first and third lines are the same as that in the second line and such that numerals greater and smaller by one than a numeral in a box of the second line appear in the third and the first lines in each column of the matrix. Further provided is a function for determining whether or not the numeral of the extracted ball coincides with the numeral of any ball mark on the display and a function for changing the mode of display of the box having the coincident numeral. Also provided is a function for determining whether any line, column or oblique diagonal line of the matrix is completed by boxes displayed in the changed display mode. Finally, a function is implemented for instructing the machine to pay medals when any line is completed.

A system for cleaning a magnetic head provided inside a rotary drum installed on a chassis in cooperation with a mechanism for guiding a tape. The system has a cleaning device including a cleaning lever capable of pivoting freely, supported by a pivot secured to the chassis, a cleaning member, a spring for urging the cleaning lever so that the cleaning member may contact with the rotary drum and a pin fixed on the cleaning lever. The system also has a tape guiding mechanism including tape guiding members and a drive member for shifting the tape guiding members, capable of pivoting freely. The arrangement permits cleaning of the magnetic head by making the cleaning member contact with the rotary drum, and also permits separation of the cleaning member from the rotary drum by making the drive member contact with the pin. The cleaning member is supported by a shaft inclining from an axis perpendicular to a reference surface of the rotary drum and having a length sufficient to reach a position corresponding to the top portion of the drum, and adapted to be shifted upward along the shaft while rotating a cleaning operation.
