PURPOSE:To put a solenoid in random operation, by previously storing a group of random numbers in a storage element, outputting the whole or part of the random number group as data in response to an output indication to the storage element, and applying values obtained through arithmetic processing to the solenoid at need. CONSTITUTION:A bottom roller 3 turns at an invariably constant number of revolution, and a top roller 3' is associated with an arm 10 oscillated on a fulcrum 11 through a solenoid 9 to be pressed against the bottom roller 3 intermittently. Therefore, the operation of the solenoid 9 is controlled by a random signal generator 12, and the top roller 3' is pressed against the bottom roller 3 repeatedly in accordance with various random pulse waves generated by the random signal generator 12. In the random signal generator 12, numbers of random numbers are stored in a group previously and once an output indication is received, data are outputted, one by one, from the random number group in sequence. In this case, a necessary random pattern is obtaned by a program for selectively extracting only data necessary for the generation of the desired random pattern. |
