An engine (10) electronically controlled by a control device (33), a hydraulic motor (24) for traveling which is driven by a pressurized oil delivered from a hydraulic pump (13), and a traveling speed switching member (29) which switches a traveling speed by the hydraulic motor (24) at least in two stages of a low speed and a high speed. The control device (33) includes an output lowering determination unit for determining whether or not a fuel injection amount to be supplied to the engine (10) is limited and an engine output is in a lowered state and a low-speed control unit in which, when the engine (10) output is in a lowered state, a traveling speed is controlled to a low speed state kept lower than a high speed even if the traveling speed switching member (29) has been switched to the high speed side.

A regeneration apparatus for executing a regeneration process to an exhaust gas purifying apparatus and an engine control device that controls a rotational speed of an engine according to an instruction value by a rotational speed instruction apparatus are provided. When a directional control valve is in a neutral position, the engine control device controls the rotational speed of the engine to an automatic idle rotational speed (Nai) by an automatic idle selection unit regardless of the instruction value. However, when it is determined that the regeneration process of the exhaust gas purifying apparatus is executed in a state of controlling the rotational speed of the engine at the automatic idle rotational speed (Nai), the engine control device increases the rotational speed of the engine to a regeneration processing rotational speed (N1) higher than the automatic idle rotational speed (Nai).

An image processing apparatus, a terminal, a printer apparatus and an image processing method for restoring, when document image obtained from an original image is read and turned to electronic data, the image data in the form of electronic data to the state of original image, are provided. An image processing apparatus reading a document image formed from an original image includes a print condition recognizing unit recognizing a mark on the read image and confirming contents represented by the mark; and an image restoring unit restoring, if the print condition recognizing unit confirms that conditions for forming a document are included in the mark, the read image to the state of original image based on the conditions for forming the document represented by the mark.

An image forming system that realizes a point system more appropriately corresponding to a degree of effects on environment is provided. The image forming system includes an image forming apparatus for giving a deduction point depending on use of resources and an addition point that is given to an energy-saving operation for the apparatus by the user, and a point management server for performing authentication processing of a user and also accumulating deduction points and addition points calculated by the image forming apparatus and managing for each user, in which an addition point calculated depending on the lapse of time passed since a user used the image forming apparatus last time and a point giving rate per unit time assigned to the user is added to the point, the point is managed for each user, and the point of a predetermined period is reported to each user.
摘要:
In a link system in which a plurality of MFPs and a server apparatus is connected so as to enable data communication over a network, a remote connection driver of the MFP starts an application on the server apparatus by remote control and at the time, on the basis of an operation start signal transmitted from the MFP, a device setting manager of the server apparatus identifies as a remote operation host apparatus the MFP having transmitted the operation start signal, and automatically sets the MFP as the MFP by which the application is used.

A front side of a floor panel (15) is pivotally supported on a floor panel support mechanism (21), permitting tilting of the floor panel in a forward direction with respect to a revolving frame (5) by way of a tilting mechanism (30). The tilting mechanism (30) has a guide rail assembly (33) which is pivotally supported on the side of the revolving frame (5), a screw rod (34) which is rotatably supported on the guide rail assembly (33), and a displacement member (35) which is attached to the floor panel (15) and held in threaded engagement with the screw rod (34). The floor panel (15) and a cab (29) are tilted up in the forward direction upon rotationally driving the screw rod (34) to translate the displacement member (35) constituting the tilting mechanism (30).
摘要:
A recording apparatus, which is provided with a carriage supporting a recording head or reciprocating along a platen, includes a magnetized scale of a magnetic linear encoder positioned along a moving direction of the carriage, and a magnetic head of the magnetic linear encoder, mounted on the carriage and adapted for reading the magnetized pattern of the scale. The scale is provided with at least two magnetized lines of mutually different pitches of magnetization, for recording position information relating to the recording operation, and position information relating to other functions.
