Abstract: PURPOSE:To enable use of an auto-calendar beyond a year setting range by providing a year limit detecting circuit, a day-of-the-week counter, a day-of- the-week switching circuit, etc. CONSTITUTION:A year counter 601 receives a one-year signal Py from a month counter 62 as an input through an AND gate 603 and outputs year information Dy. Counting thereof is 90 to 00 and 00 expresses that a range wherein a year can be set is exceeded. A year limit detecting circuit 602 detects 00 from the information Dy and outputs a day-of-the-week switching signal Pw. A gate 603 outputs the signal Py when the input of the signal Pw is absent, while it stops the output when this input is present. A day-of-the-week counter 605 receives a one-day signal Pd as an input, counts a day of the week and generates day-of-the-week counter information Dcw, while it stops counting and fixes the information Dcw at 6 when the signal Pw is not inputted. A day-of-the-week switching circuit 606, which outputs day-of-the-week calculation information Dmw from a day-of-the-week calculating circuit 64, makes switching over to the information Dcw sent from the counter 605 and outputs it when the signal Pw is inputted. In this way, display of a month, a day and the day- of-the week can be used even when a year setting range is exceeded.

IPC: G03D13/00
Filed: 1988-04-19
Abstract: PURPOSE:To uniform the temperature distribution of a sheet for image formation and to eliminate an irregularity in density after development by controlling the temperature of the center part of the outer periphery of the heat drum to temperature higher than the temperature of both end parts before the start of heat development processing. CONSTITUTION:The temperature of the heat drum 34 before the start of processing is controlled into a specific temperature distribution so that heat conducted actually to a photosensitive material becomes uniform. This specific temperature distribution is found from an experiment result and the center part and both end parts are given the same temperature characteristics by generating a temperature difference equal to the mean temperature distribution difference between both characteristics so that the center of the heat drum 34 is a specific quantity larger than both end parts. For example, both end parts of the heat drum 34 are heated by subordinate halogen lamps 46 to limit the quantity of heat radiation. Consequently, the irregularity in image density generated at the time of heat development processing is eliminated and the density distribution becomes uniform over the entire area of a photosensitive material.
