传感装置以及图像形成装置
摘要：
本发明涉及传感装置以及图像形成装置，其目的在于以良好的精度简单地判断对象体的类型。本发明的传感装置(100)包含光学系统、处理装置、支持部件、框架、以及多个弹簧部件等，框架中在对象体插入方向上规定深度之处设有窄缝。当用双手拿着作为对象体的记录纸(M)，一边在记录纸(M)上施加朝插入的左右两侧方向的拉力，一边插入窄缝时，即便是非常薄的记录纸，也十分容易插入，不会弯曲或打褶。记录纸(M)插入而被光学系统和支持部件夹持后，支持部件受到多个弹簧部件向其施加+Z方向的压力，使记录纸(M)紧贴在光学系统上，入射记录纸(M)的光的照射位置以及入射角度保持一定，从而获得稳定的反射光量。
摘要（英）：

A sensor device and an image forming apparatus incorporating the sensor device are provided. The sensor device includes a light source, a photo-detection system configured to receive light emitted from the light source and reflected at a sheet-like object, a housing accommodating the light source and the photo-detection system, the housing having a slit into which the object is inserted, and a holding member configured to hold the object such that relative positions of a surface of the object inserted into the slit and the photo-detection system are fixed. The image forming apparatus includes an image forming unit configured to form an image on a recording medium, the sensor device, and an adjustment unit configured to adjust a condition for image formation, based on an output from the sensor device.
