Problems solved by technology

However, in the process of putting the contact image sensor module into the electrostatic protection bag, even careful workers will inevitably cause a little friction between the contact image sensor module and the electrostatic protection bag, which may scratch the contact image sensor module. The image sensor module may generate dust (Particle), and even cause problems such as mirror scratches

Embodiment Construction

[0011] FIG. 1 shows a contact image sensor module 10 , a removable protective film 20 and an electrostatic protection bag 30 used in the method of the present invention. The contact image sensor module 10 includes a light source 12 , a plurality of lenses 14 , and a base frame 16 . The contact image sensor module 10 can be applied to optical devices such as a multi-function printer, a fax machine, a scanner or a copier.

[0012] When performing a scanning task, the light source 12 emits light onto the object to be scanned and is reflected, and the reflected light is focused on the optical sensor with the same width as the scanning format through the optical lens 14 (the optical sensor is located inside the optical lens 14, so FIG. 1 The optical sensor is not shown), the light intensity sensed by the optical sensor is converted into an analog signal, and after being converted into a digital signal by an analog-to-digital converter (A / D converter) for output, After processing, ...

Abstract

Disclosed is a method for protecting a contactable image sensor module from scratching, static and dust pollution. The contactable image sensor module comprises a light source, lenses, a base frame and a photoelectrical converter. The light source is used to emit light to an object; those lenses are used for receiving reflected light from the objects; the base frame is used for fixing the light source, lens and the photoelectrical converter; and the photoelectrical converter is used for transforming the incident light of the lens into electric signals. The method includes adhering protective films on the lens, the light source and the base frame of this contactable image sensor module.

Description

technical field [0001] The invention relates to a method for protecting a contact image sensor module, in particular to a method for protecting a contact image sensor module from scratches, static electricity and dust pollution. Background technique [0002] With the rapid development of optical technology, a contact image sensor module (Contact Image Sensor Module, CISM) has become a common image sensor in optoelectronic products. The existing contact image sensor module is mainly composed of a light emitting diode (Lightemitting diode, LED) array, an optical lens, and an optical sensor. When performing the scanning task, the light beam generated by the light-emitting diode is irradiated on the object to be scanned and is reflected. The reflected light is focused on the optical sensor with the same width as the scanning format through the optical lens, and the optical sensor converts the sensed light intensity into The analog electrical signal is converted into a digital s...
