Title: Current control method for solenoid, device and light transmission module
Inventor: HARADA ISAMU
IPC: H04B10/038
Filed: 1998-12-08
Abstract: PROBLEM TO BE SOLVED: To provide a current control method, which is favorable to miniaturization of a solenoid, a power saving of the solenoid and reduction in heat generated in the solenoid, and a device. SOLUTION: In a current control circuit 100 of a solenoid, when switch SW to a coil 85 is turned on, the output of a comparator 102 is kept at a high- logical level until to a capacitor 103 reaches a charged state, whereby a current limit circuit 105 is not actuated and a full current is fed to the coil 85. As this result, a strong magnetic attraction force is generated in the coil 85 and a movable core, which is located at a position apart from the coil 85, can be reliably attracted to the coil 85. After the attraction of the movable core, the output of the comparator is changed to a low logical level and the current to the coil 85 is kept small by the circuit 105. As this result, the heat generation in the coil can be inhibited and an 'on' time can be also lengthened.

When the feed roller 21 feeds sheets and the roller section 29 slides the sheets by the pressure contact of a friction pad, the groove stripes 33a, 35a, 37a of the roller section 29 slide the sheets in turn. The groove stripes 33a, 35a, 37a are displaced from each other, thus noise can be reduced when the sheets are conveyed.

Abstract: PROBLEM TO BE SOLVED: To raise operability substantially by permitting a plurality of image forming conditions incapable of being set concurrently by image forming condition setting means to be set; simultaneously, permitting the setting image plane of other image forming conditions incapable of being set to be indicated automatically. SOLUTION: A CPU operates to determine whether a function A and a function B incapable of being carried out simultaneously are selected at the same time or not, viz., a copying function to both surfaces and a copying function to an OHP sheet (S102), and when the function A and function B are selected concurrently, CPU calls a setting image plane to select the both surface copying function of the function B set previously either in function A or function B (S103). As user selects one-side surface copying button correctly (S104, 105) and selects a stop button, the CPU works to return the image plane to a popup image plane so that the OHP button can be selected (S106). Thus, user can take one-side surface copy on the OHP sheet through the selection of the OHP button.
