Abstract: A picture reader is provided with a read unit (2) equipped with a contacting member (21) which comes into contact with an original placing table (11) of a flat bed unit (1) and a pressing element (30) which presses the unit (2) against the table (11). Another picture reader is composed of a reader main body (50) having a read unit (102) and an original placing table (51), and an original cover (42) which has a light source (43) and a diffusing plate (45) and is attached to the main body (50) is an openable state, the distance to the light source (43) from a transparent original (41) placed on the table (51) being variable correspondingly to the thickness of the original (41). A still another picture reader reads in advance the accumulated difference between the movement of the optical unit (102) and a light source unit (43) and, when read scanning is started, shifts the relative position of the optical unit (102) to the light source unit (44) in the direction in which the accumulated difference is produced.

Abstract: PROBLEM TO BE SOLVED: To provide a read mechanism of an image reader that prevents uneven reading of an image caused by a difference of a moving speed between a read section and a light source for a transmission original and to provide its control method, in the image reader that is provided with the read section moved in the subscanning direction and with the light source for the transmission document that is moved in the subscanning direction synchronously with the read section to emit a light to the transmission original and that provides the read light transmitted through the transmission document to the read section and in its control method. SOLUTION: A shading main plate having an edge line tilted with respect to a read line formed to the read section is provided at an end of a light source for the transmission original and detects an offset caused by a difference of the moving speed between the light source for the transmission document and the moving speed of the read section while the reading is progressed so as to correct the moving speed of the light source for the transmission document.

Abstract: PROBLEM TO BE SOLVED: To provide a feeder whose service life can be extended by designating, out of a plurality of transportation rollers, only specified transportation rollers as ones to be replaced.
SOLUTION: In the feeder 1, a first drive system 15, a control device 18, and a pressure application system 19 operate such that the transportation force of the specified transportation rollers 121 is greater than the transportation force of other transportation rollers 122, whereby, when transporting a medium P, a load applied on the specified transportation rollers 121 is increased and a load applied on the other transportation rollers 122 is reduced. Thus, when a plurality of media P are transported by transportation rollers 12, the wear of the specified transportation rollers 121 accelerated, thereby the specified transportation rollers 121 reach their wear limit early as they wear quickly, whereas wear in the other transportation rollers 122 is suppressed. Accordingly, duration in which the other transportation rollers 122 reach their wear limit can be extended. Therefore, the service life of the feeder 1 can be extended by replacing only the specified transportation rollers 121.

Abstract translation: 要解决的问题：为了提供一种通过从多个输送辊中指定只有指定的输送辊作为替换的输送辊来延长其使用寿命的进料器。

解决方案：在进料器1中，第一驱动系统15，控制装置18和压力施加系统19的操作使得指定输送辊121的输送力大于其它输送辊122的输送力 由此，当传送介质P时，施加在指定的输送辊121上的负载增加，并且施加在另一个输送辊122上的负载减小。 因此，当传送辊12传送多个介质P时，指定的输送辊121的磨损加速，因此指定的输送辊121在磨损迅速时达到其磨损极限，而其他输送辊122的磨损为 抑制。 因此，可以延长其他输送辊122达到其磨损极限的持续时间。 因此，可以仅通过更换指定的输送辊121来延长进给器1的使用寿命。版权所有：（C）2010，JPO＆INPIT

Abstract: PROBLEM TO BE SOLVED: To provide a control method for a carrier driving mechanism which suppresses the speed fluctuation by pulsation at constant speed traveling, while executing the quick start up by shortening the start up region, in a control method for a carrier driving mechanism. SOLUTION: In the above control method for a carrier driving mechanism, it is shifted to constant speed traveling, when the acceleration generated in the pulsating carrier in its start up region becomes, minimum. A control program for prescribing the procedure of the control of the above carrier driving mechanism is stored in a computer-readable recording medium.
