Conveyance control device and image forming apparatus

Abstract

Provided is a conveyance control device including a driving unit that conveys an object to be conveyed along a predetermined conveyance path, a detection unit that detects a periodic signal for every integer cycle of a cycling member that cycles with following the object to be conveyed which is conveyed along the conveyance path, an acquisition unit that acquires conveyance speed information of the object to be conveyed based on the periodic signal detected by the detection unit and a length of predetermined integer cycles, and a correction unit that corrects an operation timing at which an operation is performed while conveying the object to be conveyed, based on the conveyance speed information acquired by the acquisition unit.

What is claimed is: 
     
         1 . A conveyance control device comprising:
 a driving unit that conveys an object to be conveyed along a predetermined conveyance path;   a detection unit that detects a periodic signal for every integer cycle of a cycling member that cycles with following the object to be conveyed which is conveyed along the conveyance path;   an acquisition unit that acquires conveyance speed information of the object to be conveyed based on the periodic signal detected by the detection unit and a length of predetermined integer cycles; and   a correction unit that corrects an operation timing at which an operation is performed while conveying the object to be conveyed, based on the conveyance speed information acquired by the acquisition unit.   
     
     
         2 . An image forming apparatus comprising:
 a driving unit that conveys a recording medium along a predetermined conveyance path;   a detection unit that detects a periodic signal for every integer cycle of a cycling member that cycles with following the recording medium which is conveyed along the conveyance path;   an acquisition unit that acquires conveyance speed information of the recording medium based on the periodic signal detected by the detection unit and a length of predetermined integer cycles;   an image forming unit that is provided so as to confront the conveyance path and forms an image on the recording medium;   an estimation unit that estimates a conveyance speed of the recording medium conveyed through an image formation region in the image forming unit, based on the conveyance speed information of the recording medium which is acquired by the acquisition unit; and   an image formation timing correction unit that corrects a timing when an image is formed by the image forming unit, based on the conveyance speed of the recording medium in the image formation region which is estimated by the estimation unit.   
     
     
         3 . The image forming apparatus according to  claim 2 , wherein
 the image forming unit forms one image formed as two or more images are superimposed on each other at a location shifted in a conveyance direction in the image formation region, and   the image formation timing correction unit corrects a timing when an image is formed by the image forming unit so as to perform registration of images formed at respective locations.   
     
     
         4 . The conveyance control device according to  claim 1 , wherein
 the detection unit has a plurality or opportunities for performing detection while the cycling member rotates one turn.   
     
     
         5  The image forming apparatus according to  claim 2 , wherein
 the detection unit has a plurality of opportunities for performing detection while the cycling member rotates one turn.
