摘要： PURPOSE: To uniformly correct the deviation in terms of dimensions of the respective spoke pieces of a cup wheel type body generated by spring back to respective prescribed angles and to perform printing without an influence on the rotary operation of the type body and the dispersion of gradation in printing density. CONSTITUTION: The entire cup wheel type body 12 is constituted by punching a metallic thin plate and many spoke pieces 12b for constituting the type body 12 are bent over to an inside slightly more than 90 deg.. By fitting a correction cup body 13 inside a housing 12H surrounded by the spoke pieces 12b, the respective spoke pieces 12b are slightly pressed and widened to an outer part and the positions and angles of type elements 12a attached at a tip are made uniform.

摘要： PURPOSE:To remarkably reduce the wear of an engaging part by transmitting the rotation of a shaft of a rotation-direction drive motor to a type holding sleeve through two studs. CONSTITUTION:Two studs 14 are fixed to a shaft 13 of a rotation direction drive motor 12 in parallel to each other. A type holding sleeve 16 is provided with through holes 16a into which linear ball bearings 18 are inserted with an appropriate clearance for allowing the vertical movement of the bearings 18 and a groove 16b into which a ball bearing 19 is inserted from outside for vertical type-selection driving with an appropriate clearance for allowing rotation. In a type-selection vertical direction, the type holding sleeve 16 moves up and down on the studs 14 by the liner ball bearings 18 in accordance with the vertical movement of the ball bearing 19. The rotation of the shaft 13 is transmitted from the studs 14 to the through holes 16a in a type-selection rotation direction. At this time, the ball bearing 19 rotates to perform a type selection in the vertical and rotation directions.

摘要： PURPOSE:To make it possible to perform high speed printing without moving a type simple up and down by an up-and-down driving motor, by setting the type simple so as to incline the same with respect to a platen printing line. CONSTITUTION:A left printing hammer 12 and a right printing hammer 13 are arranged in parallel to the center axis of a platen 4, that is, in a character printing direction and the left printing hammer 12 impacts on the lower stage type engraved to the circumferential outer surface of a simple 3 and the right printing hammer 13 impacts on the upper stage type of said simple 3. A colum nar pre-load roller 14, of which the rotary shaft is parallel to the rotary shaft of the platen 4, is provided so as to be contacted with the outer peripheral surface of the type simple 3 so as to be pressed to the outer peripheral surface of the type simple 3 by a pre-load spring 15. Therefore, the printing line on the platen 4 becomes parallel to the impact positions on the type simple by the right and left hammers 12, 13 and, therefore, the type and the printing line are kept always vertical.

摘要： PURPOSE:To enable the easy and accurate selection of an aimed type face, by forming an indented portion of discrimination by the combination of a projection and a concavity corresponding to the kind of types, the sizes thereof, etc. in an appropriate place on the flat surface of the type face. CONSTITUTION:The whole of a type face 1 is formed in the shape of a bowl with types 3 arranged in a circle. An indented portion 2 for discrimination formed on the top surface of the bottom part of the type face 1 is composed of two projections 2a disposed at an arbitrary interval on the radius which is concentric with the center of rotation of the type face 1. Since the indented portion 2 for discrimination corresponding to the kind of the types, the sizes thereof, etc. is formed in an appropriate place of the type face, many kinds of type faces can be discriminated from one another easily and speedily, and therefore, the type face can be replaced efficiently and accurately.

摘要： PURPOSE:To obtain a type selection mechanism having a high type selection accuracy, a high wear resistance, and light weight by using a system in which all the coupling movement of a sliding part is rolling coupling. CONSTITUTION:A radial ball bearing 14 is fixed in the direction of right angle to the shaft 13 of a motor 12 for driving toward turning direction. Type 15 is attached to the upside of a disc 17 fixed to a sleeve 16. A linear ball bearing 18 is set in an axially rolling manner between the shaft 13 and the sleeve 16. On the periphery of the sleeve 16, a groove 16a having a proper clearance permitting the insertion of the radial ball bearing 14 and also the rotation of the bearing 14, and also a groove 16b having a proper clearance permitting the insertion and rotation of the ball bearing 19 are provided. Since all the moving coupling of the sliding part is rolling coupling, a smoothly operating type selection mechanism which can operate only by supplying oil to the ball bearing in the early period can be obtained.

摘要： PURPOSE:To enable to securely drive a matter to be driven with a simple and compact structure by a method wherein the matter to be driven is rotatably supported and then so constructed as to be moved and displaced directly in the longitudinal direction of a supporting member. CONSTITUTION:A shaft 61 is fixed on a fixed table 60, and a rotor 62 and an armature 54 a movable iron core are supported to the shaft 61 with the relation of up and down positions. The rotor 62 is made of magnetic substance and is so formed as to freely rotate on the shaft 61. The armature 54 is also made of magnetic substance and is enabled to freely rotate on the shaft 61 and to move in the longitudinal direction of the axis. When a coil 69 is put in conduction, a magnetic flux generates in a magnetic path composed of yokes 68 and 67, the rotor 62 and the armature 54, and then the armature 54 is attracted to the rotor 62 by magnetic force. When the conductive of the coil 69 is stopped, the armature 54 moved downward under its own weight and by the action of a spring 64.

摘要： PURPOSE:To form the printer, structure thereof is simple and a type body thereof is exchanged easily, by setting up a member to be detected for a position detecting means to the shaft of a driving motor turning the type body and a member to be detected for an origin detecting means to the type body. CONSTITUTION:The type body 30 rotatable centering around a support shaft 51 is driven by the motor 60 through a gear 37 for the type body and a gear 62 fixed to the motor shaft 61 (a symbol 43 is a printing hammer). In said device, the origin detecting means 75 is constituted by an origin detector (a magnetic sensor) 76 fixed on the support body 44 side and the member to be detected (a permanent magnet) 79 fitted to the type body 30 while the position detecting means 70 is constituted by a position detector (a magnetic sensor) 71 fixed on the support body 44 side and the member to be detected (a permanent magnet) 72 fitted to the gear 62 (that is, the motor shaft 61). When the type body 30 is exchanged and the motor 60 is turned, a position signal A and an origin signal B are each transmitted from both detecting means, and a driving control circuit turns the type body 30 up to a predetermined position by the signals and stops it.

摘要： PURPOSE:To quickly damp the amplitude and vibration of a type wheel within an allowable hunting with after selection thereof by a method in which a conductive disc is provided to the drive shaft of the type wheel, and an electromagnet is provided to the disc. CONSTITUTION:A conductive disc 6 is integrally attached to the drive shaft 2 between a type wheel 1 and a motor 5, and an electromagnet 7 is provided to the disc 6 so that the magnetic flux is directed to right angle to the disc 6. When the disc 6 turns, eddy current is generated in the opposite direction to the electromagnetic direction of the electromagnet 7 to serve as a braking action, whereby quickly damping the hunting action of the type wheel 1. Therefore, the time lag in the selection of type on the type wheel 1 and the stop position of type selected can be shortened. The speed-up of the printing performance of printer and the enhancement of printing alignment can thus be realized.
