    • An optical sensor, which can be included in an image forming apparatus, includes a detecting portion disposed facing a detection target and configured to detect the detection target by emitting light to the detection target, a dust-proofing member having a surface disposed facing the detection target and configured to cover the detecting portion, a vibration member configured to vibrate the surface of the dust-proofing member, and a collecting member configured to collect dust in the vicinity of the dust-proofing member. On the surface of the dust-proofing member facing the detection target, at least a portion that intersects a pathway of light emitted from the detection portion is formed as a thru-beam part by a material through which the light transmits.
    • 可以包括在图像形成装置中的光学传感器包括:检测部,其被配置为面向检测对象物,并且被配置为通过向检测对象发射光来检测检测对象;防尘部件,其具有面向检测体的表面 目标并且构造成覆盖检测部分,被配置为使防尘构件的表面振动的振动构件和被构造成在防尘构件附近收集灰尘的收集构件。 在面向检测对象物的防尘构件的表面上,与从检测部发出的光的路径相交的至少一部分通过光透过的材料形成为贯通梁部。

    • A reflective optical sensor includes a light emitting element to irradiate a target object with a light beam, a light receiving element to receive the light beam reflected by the surface of the target object, a circuit board on which the light emitting element and light receiving element are mounted, a cover element supported on the circuit board to surround the light emitting element and light receiving element, and a light shielding wall provided in the cover element to be a partition between the light emitting element and light receiving element to prevent a part of the light beam from the light emitting element from leaking to the light receiving element. A layer in a certain thickness is formed on the surface of the circuit board along either or both sides of the light shielding wall.
    • 反射光学传感器包括用光束照射目标物体的发光元件,用于接收被目标物体表面反射的光束的光接收元件,发光元件和光接收元件 安装在电路板上以覆盖发光元件和光接收元件的覆盖元件和设置在盖元件中的遮光壁,作为发光元件和光接收元件之间的隔板,以防止部分 来自发光元件的光束泄漏到光接收元件。 沿着遮光壁的一侧或两侧,在电路板的表面上形成一定厚度的层。
