    • PURPOSE:To attain a frequency division without using a preset dividing frequency when the frequency dividing number is used fixedly, by constituting a shift register so that a serial input and a parallel input of dividing frequency data can be inputted by switching. CONSTITUTION:An output of NAND circuits 12a, 12b go to a high potential when a switching signal PT is at a low potential, a required dividing frequency is inputted to the shift register circuit 10 with an input of serial dividing frequency data DS and a dividing frequency data transfer clock signal PCK, and the frequency is latched 2 with a strobe signal S and a counter circuit 1 performs the frequency division as conventional. When the signal PT is at a high potential, the input of parallel frequency division data DP is set to an FF11 via an inverter 13 and the circuits 12a, 12b, and the input of the data DP becomes an output of the circuit 10 as it is independently of the data DS and the signal PCK. Further, the output of the circuit 10 is outputted to the circuit 1 as it is with an OR circuit 6, because the circuit 2 is independent of the signal S and the signal PT is at a high potential.

    • PURPOSE:To correctly know the used amount of recording media even when a plural number of recording media are removed or reloaded, by making an arrangement so that counting of used amount of media may be made continuously even when the recording medium is switched to another one. CONSTITUTION:The signal generated from recording media becomes one input of an AND gate 104 and the signal is input into counters 105-108. The content is always output from a Q-terminal and is input into comparators 109-112, a decoder for displaying, and multiplexers 117-120. This output is switched by a channel select switch 152 and input and stored in any one of memories 125-128, 129-132, and 133-136. When the content of the counters completely coincide with the content of digital switches 121-124, the counts are stopped by a coincidence signal from an NAND gate 142. When the recording medium is removed, a switch 103 is turned on and an AND gate 147 outputs an H-level, and then, the content of counters 105-108 is cleared. When another switch 102 is switched, the content of the memories is selected and loaded on the counters.
