摘要： PURPOSE:To prevent generation of margin wherein priming is impossible in a rolled recording sheet by providing winding rollers for bringing a recording sheet and an ink sheet into close contact with a platen roller and winding it in a predetermined angle range on the platen roller. CONSTITUTION:A recording sheet 1 is guided by a first recording sheet guide 27, introduced into a transfer passage in contact with the outer surface of a platen roller 2 from between a first winding roller 25 and the roller 2, guided to a second recording sheet guide 28 from between a second winding roller 26 and the roller 2, and introduced to second recording sheet conveying means 1. An ink sheet 22 is introduced from a supply shaft 23 between the roller 26 and the roller 2, to the transfer passage in contact on the sheet 1, and introduced to a winding shaft 24 between the roller 25 and the roller 2. In this case, the sheet 22 is wound by the roller 25 from the position of a heat generator C on the outer surface of the roller 2 in a range of 30-80 deg. at a central angle.

摘要： PROBLEM TO BE SOLVED: To shorten the axial length of a speed reduction unit which is coaxially arranged at a motor. SOLUTION: This speed reduction unit comprises: a first shaft 1 connected to the motor M; a first gear 2 arranged at the external periphery of the first shaft 1; a second gear 3 engaged with the first gear 2; a second shaft 4 which supports the second gear 3; a third gear 5 which is rotatably supported by the second shaft 4, and arranged at the motor M side with respect to the second gear 3; a clutch 6 which switches the transmission and the disconnection of rotation between the second shaft 4 and the third gear 5; and a differential device 7 which distributes the rotation of the third gear 5 to right and left wheels. The speed reduction gear also reduces the rotation of the motor M in speed in a connection with the clutch 6, and transmits the reduced rotation to the right and left wheels. An outer ring 30 of at least one bearing among bearings 37, 39 which rotatably support the end of the first shaft 1, and bearings 29, 40 which rotatably support the end of the second shaft 4 is constituted of a large-diameter part 31 and a small-diameter part 32 which is smaller than the large-diameter part 31 in outside diameter, and the outer ring 30 is fixed by pressing down the end face of the large-diameter part 31 by using a plate 35.

摘要： PROBLEM TO BE SOLVED: To provide a data processing system that is a foundation to construct an information system capable of flexibly corresponding to a change of access object data and further to provide a mechanism which improves the performance of the data processing system needing distributed inquiry processing. SOLUTION: The data processing system which receives an inquiry from an application is provided internally with a virtual table capable of multiple mapping to a plurality of databases (1). A partial replica being the copy of a part of data on the virtual table is prepared, and all or a part of the inquiry is processed by using the partial replica (2). Also, about an inquiry unit in which the partial replica can not be used, appropriate distributed join system selection and optimization that pushes down processing to a real database as much as possible are used.

摘要： PROBLEM TO BE SOLVED: To provide a drive device having a simple structure for an automatic paper supply device in a thermal transfer recorder. SOLUTION: A D cut roller which comes into contact with recording paper in a paper supply tray to transfer paper is provided in a case body 3b of an automatic paper supply device of a thermal transfer recorder, and the roller is driven by a drive device 350. A drive gear 352 which meshes with a transmission source of power meshes with a pinion 353 attached to an arm 351. A slider 360 of which position is regulated by a cam of a controller operates this arm 351 to connect and disconnect the mesh between the pinion 353 and a gear 355. When paper is supplied, the drive gear 352 is driven in the direction of arrow W1, and the pinion 353 meshes with the gear 355 to drive a paper supply roller.
