A device includes a sound source, an electric board, an exterior member, an electric board container box, and a sound absorber. The sound source generates a sound at a time of operation. The electric board has a circuit mounting an electrical component. The exterior member surrounds the sound source and the electric board. The electric board container box houses the electric board. The sound absorber is at least partially disposed inside a virtual space corresponding to a thickness of the electric board container box in an interior space of the device.

A fuel filler system for use in a vehicle is provided. The system includes a fuel filler tube, a locking bracket coupled to an inner surface of the fuel filler tube, and a closure device coupleable within the tube end and including an outer wall and a radially movable tab extending from the outer wall. The tab engages the locking bracket after rotation of the closure device from a first rotational position to a second rotational position to prevent rotation of the closure device relative to the locking bracket. The closure device further includes a web flexibly connecting the tab to the outer wall and a region of weakness defined in the web, such that upon forcible rotation of the closure device from the second rotational position to the first rotational position, the region of weakness facilitates separation of the web from the outer wall.

An image forming apparatus includes an image bearing member, a plurality of developing devices, a transfer device, a moving device, a color drift detector, a test pattern forming device, and a color drift correction device. The test pattern forming device forms a test pattern on the image bearing member. The color drift correction device corrects the color drift in a separating state in which the image bearing member and the transfer device are separated from each other. The test pattern forming device forms the test pattern again in an area on the image bearing member contacting the transfer device but not pressed by the transfer device after the color drift correction device corrects the color drift in the separating state, and the color drift correction device corrects the color drift in the contact state in which the image bearing member and the transfer device are in contact with each other.

In a sheet creaser, a sheet set is pushed between a pair of folding rollers to fold the sheet set. Then, a re-pressing roller re-presses the sheet set, which has been folded by the folding rollers, by rolling along the crease. Pressure applied on the sheet set by the folding rollers is released when the re-pressing roller re-presses the sheet set.

A state determining device includes a current detecting unit, a state determining unit, and a notifying unit. The current detecting unit detects a current value of a drive current which flows into a drive motor that rotary-drives a driven unit with a drive force according to the drive current. Based on the drive current value detected by the current detecting unit, the state determining unit determines a state of a driving system including the driven unit. The notifying unit notifies a user of a determination result of the state determining unit.

The danger of a jib falling off a boom due to an erroneous operation during movement of the jib between a stowage position and an extended position is eliminated. The jib is provided with a pivot pin insertion state detector, pivot pin retraction blocking element, a coupling pin insertion state detector, first and second cables, wherein movement of a coupling pin to a retracted position is restricted by a coupling pin retraction blocking element via the first cable when the pivot pin insertion state detector has detected that the pivot pin is retracted, and movement of the pivot pin to the retracted is restricted by the pivot pin retraction blocking element via the second cable when the coupling pin insertion state detector has detected that the coupling pin is retracted, so that simultaneous removal of both of the pivot pin and the coupling pin is prevented.

A conveying device that conveys a sheet bundle with a flattened back-face portion includes a first conveying unit, a driving unit, and a second conveying unit. The first conveying unit retracts to a position where no driving force is exerted on the sheet bundle before a leading end of the sheet bundle formed in a flat spine shape enters, and abuts on the sheet bundle to exert conveying force after the leading end of the sheet bundle passes a conveying position. The driving unit moves the first conveying unit to retract to the position and to abut on the sheet bundle. The second conveying unit is positioned on an upstream side of the first conveying unit in a sheet bundle conveying direction and conveys the sheet bundle towards the first conveying unit.
