摘要： An image recording apparatus which records an image of an original document on an image receiving sheet with the use of a photosensitive recording medium, the image receiving sheet having front and rear faces differing in reflection ratio. To detect error in sheet face orientation, a sheet face sensor unit is provided upstream of a pressure developing unit which discriminates a face of the image receiving sheet. The sensor unit includes a light emitting element for emitting light toward the face of the image receiving sheet and a light receiving element for receiving light emitted from the light emitting element and reflected on the face of the image receiving sheet. A central processing unit is supplied with data representative of amounts of light emitted from the light emitting element and light received at the light receiving element, wherein the central processing unit computes a reflection ratio based on the data supplied thereto and produces a discrimination signal indicative of an error in sheet face orientation of the image receiving sheet based on the reflection ratio being computed.

摘要： The invention particularly relates to a solenoid valve used in a control fluid, and one end of a center pole on the side opposite from a plunger is covered with theend face of a housing, and a communication passage is formed in the housing to communicate a through hole of the center pole with an opening formed on the housing on the side of the plunger. The communication passage has an end face groove and at least one side face groove on the end face and the side face of the housing. A volume of the side face groove is larger than a variation in volume of a space between the plunger and the center pole due to the movement of the plunger, and it is 2.5 times or more of the variation in volume of the space between the plunger and the center pole due to the movement of the plunger. Thus, the control fluid of the plunger on the opposite side from the center pole is reduced to enter along the outer periphery of the plunger into the space between the plunger and the center pole, and impurities can be easily and reliably prevented from being accumulated between the center pole and the plunger.
摘要翻译：本发明特别涉及一种在控制流体中使用的电磁阀，并且与柱塞相反一侧的中心极的一端被壳体的表面覆盖，并且在壳体中形成连通通道，中心极的孔具有形成在柱塞的侧面上的壳体上的开口。连通通道具有端面槽和在壳体的端面和侧面上的至少一个侧面凹槽。侧面凹槽的体积大于由于柱塞的移动而导致的柱塞与中心柱之间的空间的体积变化，并且是柱塞之间的空间的体积变化的2.5倍以上并且由于柱塞的运动引起的中心杆。因此，与中心极相反一侧的柱塞的控制流体被减少以沿着柱塞的外周进入到柱塞和中心极之间的空间中，并且可以容易且可靠地防止杂质累积在中心杆和柱塞。
