Title: Recorder
Inventor: MIURA MAKOTO
IPC: G03G21/02
Filed: 1982-09-16
Abstract: PURPOSE:To improve the operability by operating a stepwise increasing or reducing key of planned copy number starting from a nearest initial value. CONSTITUTION:The copy operation is started by a copy key 10 and the number of copies is set by a stepwise increasing or a stepwise reducing key 9 or 8 and is displayed on a display device 11. The numerical value displayed on the display device is set to a prescribed initial value by a clear key 7. In an operating part 2, if the key 8 is operated after the numerical value on the display device 11 is cleared by the operation of the key 7 and a minimum number of copies, for example, ''1'' is set, a preliminarily set and stored maximum initial value is displayed on the display device 11 because the number of copies to be a positive integer cannot be set by subtraction from minimum value ''1''. Consequently, the maximum initial value is set to a value nearer to the number of copies which is set frequently, and this maximum initial value is increased or reduced, thus attaining a prescribed set value with a small number of operations.

The contents of the counter 5 are added to the contents of the memory circuit 103 by an adding circuit 102 and the sum is transmitted to a dividing circuit 104. The counter 101 counts the output of the comparator 4 to generate and output frequency information to the circuit 104. A mean value generated by the circuit 104 is transferred to the memory of an exposure control circuit 8 on every integrating operation to control exposure control by using the light measurement output in which the influence of a flicker is eliminated.

Abstract: PURPOSE:To reduce number of times of relay and to decrease the transmission time by selecting a unit so as to closest to a final arrival unit when a data is exchanged with a unit at a location which no radio wave is directly reached. CONSTITUTION:In the case of sending a data from a controller 11 to, e.g. a controller 15, the controller 11 transfers the data with information representing the final destination to be a unit 5a to the radio communication unit 1a.
