Provided is a printing apparatus, including a sensor unit which optically detects, at a measurement position, a surface of a sheet, for measuring a moving state of the sheet. The sensor unit measures the moving state of the sheet when the sheet is located at the measurement position, and measures a moving state of a surface of the rotary member when the sheet is not located at the measurement position.

A printing apparatus includes a plurality of image sensors imaging a sheet to be conveyed, and a direct sensor unit performing the signal processing of the outputs of the image sensors to detect the movement of the sheet. Here, the plurality of image sensors are provided on the carriage at least at two positions with at least the recording element array diagonally put between the two positions. The plurality of image sensors can image the sheet at two positions separated in a main scan direction and a sub-scan direction.

An original stacking plate for supporting and stacking an original is rotatably attached to an ASF base. A fulcrum position of the original stacking plate is provided with a rotational center on the upstream side in the sheet feeding direction from a fulcrum position of a pressing plate while keeping a predetermined distance from a base surface of the ASF base. Therefore, a rotational angle of the original stacking plate in association with the vertical motion of the pressing plate when the original and recording paper have been set is smaller than that of the pressing plate.

The present invention provides a taphole cooling structure allowing prevention of wear and deformation of peripheral bricks of the taphole and maintaining stable operation of the furnace in high copper matte grade operations and high load operations. The taphole cooling structure is provided with a hollow jacket body to be inserted into an opening penetrated on a furnace wall, wherein a water passage is installed in the internal of the jacket body for circulating cooling water while a flange made of the same material as the furnace wall is provided on the periphery of said jacket body to be weldingly connected to the said furnace wall, wherein a refractory material is filled within a hollow of the said hollow jacket body and perforated with a taphole for draining solutions from the furnace body.

An image reading and recording apparatus has: a carriage for mounting a recording head; a reading unit which reads an original document; a conveying roller arranged on a conveying path which is used in common for recording paper and the original; and a platen arranged so as to face the recording head. The reading unit is movable between a reading position on an upper side of the conveying path and a retracting position on a lower side of the conveying path. The platen can relatively and independently move for the reading unit.

A disk recording and/or reproducing apparatus in which a disk-shaped recording medium such as an optical disk is able to be transported between a disk loading portion for recording and/or reproducing information and a disk entrance and exit slot into and from which the disk-shaped recording medium is inserted and ejected. The disk recording and/or reproducing apparatus includes a pair of transport rollers which can hold the disk-shaped recording medium in the diametrical direction and a drive means for rotating a first transport roller of the pair of transport rollers and wherein a second transport roller of the pair of transport rollers is fixed and the drive means rotates the first transport roller to rotate the disk-shaped recording medium by rotation force so that the disk-shaped recording medium is transported between a disk loading portion for recording and/or reproducing information and a disk entrance and exit slot.
摘要:
A production method of an acoustic diaphragm including the steps of: forming an acoustic diaphragm-shaped workpiece with a flange portion added to at least a portion of an outer periphery of the workpiece by using a natural material including an organic matter which can be carbonized by burning; impregnating a solution including phenol resin into the workpiece obtained at the above step, and then heating the workpiece to a predetermined temperature to bring the phenol resin into a high polymer state; and burning the workpiece processed at the above step under a substantially anoxic atmosphere to carbonize the organic matter.

An original stacking plate for supporting and stacking an original is rotatably attached to an ASF base. A fulcrum position of the original stacking plate is provided with a rotational center on the upstream side in the sheet feeding direction from a fulcrum position of a pressing plate while keeping a predetermined distance from a base surface of the ASF base. Therefore, a rotational angle of the original stacking plate in association with the vertical motion of the pressing plate when the original and recording paper have been set is smaller than that of the pressing plate.
