Abstract

PURPOSE:To reduce cost and to improve operability by operating and displaying selectively plural modes through less operational buttons. CONSTITUTION:When a recordable cassette tape is loaded at the cassette holder part 29 of a video tape recorder main body 28, the operational button 12 which acts as a mode group switching button and switches video-recording and reproducing modes is depressed to cause the operation in the video recording temporary stop state, which is displayed on a crystal liquid display board 18. When said button 12 is pressed in such the state, the operation is made in the still picture reproduction state, which is displayed on the crystal liquid display board 18. If one operational button 12 is operated in such a way, the functions and display contents of other five operational buttons 13-17 can be switched. Thus the space for five operational buttons and the number of parts can be reduced. Moreover a board having an arbitrary size can be used as a crystal liquid display board, and the size of the operational button and its disposing interval have the comparative degree of freedom, thereby improving the display ability and the operability.
