Title: Image forming device
Inventor: MAKINO MASAHIRO
IPC: G03G21/14
Filed: 2017-10-23
Abstract: To suppress occurrence of an image defect attributable to a change of toner charge amount due to toner supply when executing a full-color mode after a drum-stuck monochrome mode.SOLUTION: According to the present invention, a control unit detects a toner concentration in accordance with a detection result of an inductance sensor for each sheet of a recording medium (S2) and computes am amount of deviation (S4) that is a difference between the detected toner concentration and a read-out target toner concentration (S3). The control unit finds a supply amount of toner to be supplied by a toner supply device in accordance with the amount of deviation (S5) and supplies toner in according with the supply amount (S6). At this time, toner is supplied at a smaller change rate than a toner concentration change per unit time when a full-color mode is executed with a first threshold or higher until the toner concentration becomes the first threshold or higher. Thus, it is possible to suppress occurrence of a change of toner charge amount by having the toner concentration restored to an appropriate range slowly, and therefore to suppress occurrence of an image defect attributable to a change of toner charge amount due to toner supply.SELECTED DRAWING: Figure 6

Title: Imaging apparatus
Inventor: ONODERA HIROAKI
IPC: H04N5/225
Filed: 2017-10-27
Abstract: To solve the following problem: Lateral streak noise occurs in an image due to an influence of power supply noise superposed during read-out of a noise signal of an image pickup device and read-out of an optical signal component.SOLUTION: A drive frequency of a switching power supply in an imaging apparatus is generated to synchronize with an inverse number of a time difference between read-out of an optical signal and read-out of a noise signal, thereby equalizing potential levels during read-out of an optical signal and read-out of a noise signal with each other. Further, by executing phase control, a generation region of sudden power supply fluctuations in the switching power supply is avoided and an influence of power supply noise from the switching power supply on a picked-up image is suppressed, thereby suppressing generation of lateral streak noise appearing on the picked-up image.SELECTED DRAWING: Figure 6A

IPC: A63F7/02
Filed: 2017-11-07
Abstract: PROBLEM TO BE SOLVED: To provide a game machine capable of simplifying drive control of a movable accessory and reducing a burden of linked control with variation performance control.SOLUTION: Regardless of whether a rotating shaft 141a of a motor is driven in a forward direction or in a backward direction, a first movable accessory 71 (small turtle) starts moving in the same direction (for example, a neck lowering direction) from its initial posture, so that only one of a forward drive signal and a backward drive signal may be outputted when driving the first movable accessory 71 (small turtle), thus simplifying drive control of the first movable accessory 71 (small turtle). Even during a drive period of the first movable accessory 71 (small turtle) in a variable display performance, only one of the forward drive signal and the backward drive signal may be outputted, thus dispensing with control for alternately outputting the forward drive signal and the backward drive signal, and reducing a burden of linked control with the variable display performance.SELECTED DRAWING: Figure 15
