Abstract

PURPOSE:To transfer various warnings to fingers tactually, by the constitution where the operation material of a camera is vibrated electrically, magnetically and mechanically by the output of a warning signal generating means incorporated in the camera. CONSTITUTION:This device indicates the time near the end of the loaded film and the end time with tactual indication; and when approximately 30 pictures are taken, for example, in case of the film for 36 photographs, switch 13 interlocking with the rotation of the film counter is turned on, and the signal of a constant frequency is applied to coil 12, and release button 1' made of the permanent magnet material is vibrated. When 36 pictures are taken, switch 13' is turned on to connect resistances 9 and 9' of the multivibrator in parallel, and the oscillation frequency of the multivibrator is changed to the high frequency side, and the oscillation frequency of release button 1' of the permanent magnet is changed also.
