PURPOSE:To easily inform the number of necessary jackets, by decoding a counting value of a counter for counting stepwise whenever a counting output at every photographing attains to a prescribed value, generating a pulse, and displaying a counting value of this pulse. CONSTITUTION:The number of films strips S stored in a pocket 200 of a jacket 100 to be used is set to a storage circuit 2 through a keyboard 1. When this set value coincides with a counting value of a photographing signal by the first counter 3, a pulse is generated from a pulse generator 5 through a comparing circuit 4, a counting value of the speed counter 6 is forwarded stepwise, and also the counter 3 is reset. Subsequently, when the counting contents of the counter 6 coincide with the number of pockets 200 of the jacket 100, a pulse is outputted through a decoder 7 and a pulse generator 8, and the third counter 9 counts the number of necessary jackets. Its result is displayed on a display device 10, and the number of necessary jackets is informed easily at the time of photographing. |
