PURPOSE:To enable simultaneous indication of current time and residual time in a sleeve on the same display by indicating the residual time on a second indicating section of the current time. CONSTITUTION:When a sleeve switch 4 is closed, a switch 4a is turned on to reset an RS type FF35 and a low level output Q allows an AND gate 36 to be opened thereby leading an AND gate 39 connected to an inverter to open. Consequently, current second time fails to be applied to a second indicating section 13b of the current time from a second counter 17a and in stead, the residual time in the sleeve such as minute and the like is applied thereto based on a down-counting of a sleeve counter 38. This enables the current time and the residual time in the sleeve to be indicated simultaneously on the same time display, i.e. the current time on the hour/minute indicating section, and the sleeve residual time on the second indicating section. |
