Abstract

PURPOSE:To improve the convenience of use by displaying only the ISO data in the stage of setting the ISO data and displaying the photographing data changing with exposing time data in the stage of setting the exposing time data to be selectively set according to the individual photographing. CONSTITUTION:The space in a display part is reduced by displaying ISO data and exposing time control data APC with a display part DPC which is used commonly to display both data. The other data for photographing is displayed on the other display part while the data APC is under display. The other data for photographing changing in individual shots is thus displayed in combination, by which display information is increased and the convenience in using the camera is improved. Only the ISO data is displayed in the stage of setting the ISO and the change at every individual shot is obviated during use of one film. The equivocality in the display of the data is prevented by displaying only the ISO data.

If the output is not normal and the ISO data is not read based on the data from the film container and fixed ISO data is set, this data will be displayed blankly for 10 seconds. A warning will be given. Furthermore, if it is determined by bit 2 of register MOR that the film counter switch (CFS) is open, the terminal (
02) and (04) are set to Low. Therefore, the terminal (iLA) is set only when the ISO switch (IsS) is closed.
Since an interrupt signal is input to the camera, even if the release button is operated, the exposure control operation is not started and the release is locked. To get out of this state, use the ISO switch/
You can either operate the key or wait 100 seconds. Also, if it is determined that the film counter switch (CFS) is closed, there is a low possibility that film is being loaded.
