ABSTRACT:
A program-selecting device is used for a reproducing apparatus for reproducing at fast-forward speed or normal speed a recording medium on which a plurality of programs are respectively and distinctively recorded. The program-selecting device comprises a switch for program number selection which is manipulatively operated a number of times corresponding to the number of programs to be skipped over to reach the desired program, a memory circuit for storing the number of times the switch is thus operated, a counting circuit for detecting the parts between adjacent programs from the signal reproduced at fast-forward speed from the recording medium thereby to count the number of programs skipped over at fast-forward speed, a comparison circuit for producing as output a coincidence signal when the output of the memory circuit and the output of the counting circuit coincide, a mechanism for operating in response to said coincidence signal to change the fast-forward reproducing mode of the recording medium of the reproducing apparatus over to the normal reproducing mode, a display part comprising a set of display elements provided in a plural number corresponding respectively to the number of program numbers which can be selected, the display element corresponding to the program number of the selected program being lit, and a lighting circuit activating the display elements corresponding to the counted skipped over program to lite such in a mode different from the mode in which the display element corresponding to the selected program number is lit.
