Title: Image forming device
Inventor: NIWA MINORU
IPC: G03G15/16
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain high image quality and to facilitate maintenance by suppressing the occurrence of paper powder in a transfer-paper carrying path by abutting each of carrying means on a transfer paper just after the passage of the front end of the transfer paper passing through the position where the carrying means are set, and releasing the abutting just before the passage of its rear end. SOLUTION: When a paper-front-end detector 7 detects the front end of the transfer paper 4 after an image forming process is started and the paper is started to be carried, a carrying control means 9 makes the time required for carrying rolls to form a nip longer only by the time required for the front end of the transfer paper 4 passes between the pair of rotary rolls as the carrying rolls 6. Thereafter, a retraction control means 10 makes a retreating means 8 form the nip between the pair of rotary rolls, composing the carrying rolls, and then the carrying of the transfer paper 4 is executed. When the paper- front-end detector 7 detects the rear end of the transfer paper 4, the carrying control means 9 commands the retraction control means 10 to carry out the retraction of the retracting means 8, so that the carrying rolls 6 are released from the paper nip.

Filed: 1984-03-09
Abstract: PURPOSE:To attain the clear reproduction by applying an output with the inverse characteristic to a reproduction input to a preamplifier as an automatic level adjusting voltage so as to decrease sound recorded surrounding noise. CONSTITUTION:A sound recorded sound input is AC-amplified by an AC amplifier circuit 30 at the reproduction, rectified at a rectifier circuit 32, converted into a DC voltage having the inverse characteristic to the input and inputted to a differential amplifier 34.

Then, when information indicating transition to a synchronizing code detection mode is communicated from the mode judging part 22, the power source of the RF part is turned ON during the maximum 576 bits from the point of time as start. When a synchronizing code is detected, transition to the synchronizing mode is realized, and when any condition of pull-out is not established, and its own address is not present, the power source of the RF part is turned OFF.

Abstract: PURPOSE:To indicate the warning which meets actual conditions more than before by inhibiting the warning from being indicated, regardless of the result discriminated by an inappropriate original size discriminating means, when an original having half the size of a maximum original is selected. CONSTITUTION:When the original having an inappropriate size might be selected by an original size selecting means 21 because of its relationship with a copying sheet size, contraction ratio or the like, the inappropriate original size discriminating means 22 discriminates it; and a warning indicating means 23 indicates the warning by using a display, buzzer, etc. A warning indicating inhibiting means 24 inhibits the warning from being indicated, regardless of the result discriminated by the inappropriate original size discriminating means 22, when the original having half the size of the maximum original capable of copying is selected by means of the original size selecting means 21. That is, when the original having half the size of the maximum original capable of copying is selected by means of the original size selecting means 21, the warning is not indicated. Thus, the indication of the warning on handling such as original meets the actual handling conditions more than before.

Title: Nozzle cleaning method of ink jet printer
Inventor: RI SAIKAN
IPC: B41J2/18
Filed: 1996-03-01
Abstract: PROBLEM TO BE SOLVED: To provide a method for cleaning nozzles which wastes ink less in an ink jet printer of a multi-nozzle head. SOLUTION: A counter starts counting at a printing start (step E). A less frequently used nozzle group is cleaned when a count value (t) corresponds to a cleaning cycle T1 (steps G and H). A frequently used nozzle group is cleaned when the count value (t) corresponds to a cleaning cycle T2 (steps I and J). The cycle T1 is set to be shorter than the cycle T2. In other words, the cleaning cycle for nozzles is set in accordance with the frequency of use of the nozzles and, the number of cleaning times is restricted for nozzles that require less cleaning. In comparison with the conventional case where all nozzles are simultaneously cleaned at one time, a consumption amount of ink can be reduced and a life of an ink cartridge is increased. Moreover, a discharge amount of ink is also reduced, whereby a waste ink cartridge can be made small and a life can be extended.
