(vol%) value of exhaust gas obtained on the basis of the concn. signal from the detector 4 by operating the changeover valve 3 and the value calculated from a correction formula to a display device 6 to display them thereon. When the calculation gas (usually, a gaseous mixture of nitrogen gas N2 and oxygen gas O2) is measured, a means controllable by the CPU 5 is used as the changeover valve 3 to avoid this correcting operation. When gas clearly containing no CO2 is measured, correction processing may be omitted.

Title: Camera
Inventor: ARIFUKU KIYOSHI
IPC: G03B17/18
Filed: 1984-12-28
Abstract: PURPOSE:To exactly grasp the operating condition of a camera, by displaying the success of initial feeding of a film without taking photographs by sending a signal to an indicator irrespectively of the state of a barrier switch when the initial feeding is successful. CONSTITUTION:When a barrier is closed and a barrier switch 4 is turned off and, as a result, a photographing-able condition is not set, an indicator 36 does not make any indication. When the initial feeding operation of a film without taking photographs is started and a counter 20 counts the operation of a sprocket switch 5 for the four frames of the film, the count value is displayed by the indicator 36 by means of the signal of a control circuit 36 irrespectively of the barrier. The display is erased after a prescribed time has passed from the termination of the initial feeding operation and displayed only when the barrier is opened. Since the display of the indicator 36 is automatically erased when the success of the initial feed operation is confirmed in such a way, useless consumption of a battery can be prevented while the operating condition of a camera is exactly grasped.
