Title:
METHOD FOR ADJUSTING SENSOR
Document Type and Number:
Japanese Patent JP2000057399
Kind Code:
A
Abstract:

To remove a manual working process and to shorten adjusting time by preparing a sheet of adjusting reference paper by printing or sticking a material having a different reflection factor to a part of a sheet of paper having a reference reflection factor setting up the reference paper on the upstream of a carrying means and detecting the printed or stuck part of the reference paper moved by the carrying means by a reflection sensor.

The reference paper 21 has a band-like black printing part 21b on a part of a sheet of paper having the reference reflection factor. It is not always required that the printing part 21b is black but it is required that the printing part has a reflection factor sharply different from that of the paper sheet and it is also available to stick a sheet member having a different reflection factor e.g. to the paper sheet. The reference paper 21 is set up on the upstream of the carrying means, the printed or stuck part of the reference paper 21 moved by the carrying means is detected by a transmission sensor, and after moving the reference paper 21 from the detection position by a prescribed distance, the carrying means is stopped and the transmission sensor is adjusted by the reference paper 21. After completing the adjustment, the reference paper 21 is carried to the downstream of the carrying means.
