Abstract

PURPOSE: To facilitate an easy handling of the cards by inserting the card in the row direction of the projection and presetting the receiving frequency, and then to increase the number of the card without increasing the installation space.
CONSTITUTION: Card 11 featuring the bit constitution through which the desired receiving frequency is designated is put into card insertion slit 15, and then shifted flexibly in the row direction of projection 13. In this instant, switch 18 is turned on, and the illumination light given from each light emitter 16 is supplied to light receiver 17 via the projection part. Then logic value 0 and 1 are delivered from each receiver 17 by the presence or absence of projection 13. This output is then supplied to the memory and the like for preset use to read out the desired value. Thus, the division ratio of PLL is designated, and the preset is given to the receiving frequency
