PURPOSE:To increase frame speed and to always maintain the optimum operating time of a stopping means by computing data for the optimum exposure of a film and the data of winding up of the film with the aid of a data inputting and computing means and a system controlling means in parallel with the operation of the stopping means of winding the film. CONSTITUTION:When the specified amount of a wound file is detected by winding detecting means 11-13, a driving means 19 is made inoperative, the stopping means 20 is operated for a prescribed time, and whole part or a part of process is operated by the data inputting and computing means and the system controlling means in parallel with the operation of the stopping means 20, I.e., process during the operating time of driving and braking circuits is carried out at the same time as far as possible. Thus, the operating time of the brake is effectively used and the time of photographing action can be abbreviated, i.e., the frame speed can be increased. |
