Title: Picture reader and picture reading method
Inventor: MIYAKE MIHO
IPC: H04N1/04
Filed: 1998-03-19
Abstract: PROBLEM TO BE SOLVED: To provide a picture reader which can avoid such an inconvenience that an optical system cannot be stopped within a stop range through the use of a previously calculated correction value when a scanning length changes too much. SOLUTION: For executing a correction processing for subtracting or adding time until a first brake is operated from the detection of a prescribed position based on a difference in distance between a target distance where an original reader is moved to a read start position after the read operation of an original terminates and a real moving distance, it is discriminated whether or not a scanning length is the same as the last scanning length of the copy job of previous time (S703). When the scanning length is discriminated to be different, the value of a correction value table, which corresponds to the calculated scanning length, is read and a correction processing is executed by a correction value which is set by reading (S704).

The water pressurre in the discharge side water passage on the downstream side from the governor valve 19 decreases and is controlled to 1kg/cm 2 . When the pressure governor valve 19 shifts upward, the opening 26 of a jet feedback water passage is opened, and a portion of the water which flows in the discarge side passage 18 returns to the jet nozzle of a turbine jet pump 12, and the pump operates a jet pump. Therefore, the discharge side pressure does not rise above necessary, and the apparatus can be used suitably for the water feeding apparatus to a boiler in which pressure is limited.

Abstract: PURPOSE:To simplify constitution by inputting code information, etc., all at once as the activating means of a utility program with an existing operating part. CONSTITUTION:The period from an (a) point to a (b) point is the one of one code input, and during the period, a TM (timer) is cleared with a bit signal SW becomes '0 1' or '1 0,' respective types of the time are measured. For example, after the bit signal SW is changed to '0 1,' when a switch 2 is released before the condition of SW='1' passes for more than 2 seconds, the said input bit data are discriminated to be '0.' After the bit signal SW is changed to '0 1,' when the condition of SW=1 passes for more than 2 seconds, the said input bit data are discriminated to be '1.' Consequently, the correct input of bit data '0' is executed by releasing the switch 2 within two seconds, and the correct input of bit data '1' is executed by releasing a switch more than 2 seconds less than 5 seconds. By such an input means, the code for the activation of the utility program is inputted.
