摘要:
An image forming apparatus that can satisfy productivity at the time of double-sided image formation without jamming due to a collision of a succeeding sheet with a preceding sheet, and without upsizing of the apparatus. The image forming apparatus performs a sheet circulation transport for circulating and transporting a sheet to an image forming unit to perform image formation on both a first side and a second side of the sheet. The sheet is fed to the image forming unit at a predetermined image formation start timing for the first side image formation. The first side image-formed sheet is reversed, and re-fed to the image forming unit for the second side image formation while causing the first side image-formed sheet to wait at least one of sheet waiting positions. A full state where all the sheet waiting positions are full of the first side image-formed sheets is detected. The sheet feeding unit is controlled so that the number of sheets on which the sheet circulation transport is performed is greater than the number of the sheet waiting positions. When the full state detecting unit detects the full state, the sheet re-feeding unit is controlled so that a head sheet among the first side image-formed sheets waiting at the sheet waiting positions is fed in advance of the predetermined image formation start timing.

An image forming system which is capable of causing a clear coating apparatus to discharge processed sheets in proper page order, and improving usability and operability of the system by users. An mage forming apparatus is set to perform single-sided image formation or double-sided image formation. A clear coating apparatus is set to perform single-sided clearing coating or double-sided clear coating. Whether to perform inverted discharge of sheets is controlled according to the settings of the image forming apparatus and the clear coating apparatus.

A printer system capable of reducing wasteful power consumption by apparatuses forming the printer system and preventing the service lives of the apparatuses from being shortened and capable of optimizing the capacity of power source. When power of the apparatuses of the printer system is on, a slave controller of each apparatus calculates a preparatory operation time of the apparatus, and transmits the calculated preparatory operation time to a master controller. Based on preparatory operation times indicated by data received from the slave controllers, the master controller determines start-up commencement times (start-up timings) of the slave controllers, and requests (instructs) the slave controllers to start operations upon elapsed of the determined start-up commencement times. In response to received operation start requests, the slave controllers start preparatory operations.

A true/false determining apparatus that can determine the genuineness of a material with high accuracy. Coherent light is radiated onto a surface of an object. Reflected light of the coherent light reflected by the object detecting unit is detected. A part to be used as a pattern sample from intensity distribution of the reflected light detected by the detecting unit is selected. Pattern data is generated from the intensity distribution of the reflected light in selected the part. The generated pattern data is matched against reference pattern data.

In an ADPLL composed of a digital circuit, a technique improving phase difference detection in a vicinity of a phase difference of 0 (zero) is provided. A feedback loop comprises a PFD comparing phases and frequencies of a reference signal and a feedback signal, a TDC converting an output of the PFD into a digital value, a DLF removing a high frequency noise component from an output of the TDC, a DCO controlled based on an output of the DLF and a DIV frequency-dividing an output the DCO and outputting the feedback signal. An offset value is added at any portion of the feedback loop, a phase of the feedback signal is controlled and a value other than 0 is inputted to the TDC even when the ADPLL is locked.
