摘要： PURPOSE:To easily mount a protecting cover in a simple structure by forming an outer peripheral surface of said protecting cover of a member having low thermal conductivity and fixing said protecting cover by an elastic force generated through elastic deformation of a part of said protecting cover. CONSTITUTION:A radiator 1 of a head is covered with a net-like protecting cover 2 having low thermal conductivity. Therefore, it can be prevented, without deteriorating the radiating property, that a user inadvertently touches the surface of the head at high temperatures. An end of a fixed hook 3 of the protecting cover 1 is inserted in a grooved portion between a first fin 4 and a second fin 5 of the radiator 1. The protecting cover 2 is guided to slide downward along the grooved portion, so that the fixed hook 3 is engaged with an engaging portion 6 of the radiator 1. The grooved portion of the radiator 1 is formed tapered, having a different depth between upper and lower portions thereof. Since the groove at the upper portion is deep, the protecting cover 2 is readily guided by the tapered groove only by being pressed downward, and the fixed hook 3 expands right and left to be smoothly engaged with the engaging portion 6. When the fixed hook 3 is engaged with the engaging portion 6 of the radiator 1, the fixed hook 3 is pressed to the radiator 1 by the elastic force, whereby a positive fixing force is obtained.

摘要： PURPOSE:To miniaturize not only a printed circuit board but also an impact dot head main body by arranging one connector or a plurality of connectors corresponding to the number of needles for connecting the relay cable from a head driving circuit board and a printed circuit board on the printed circuit board. CONSTITUTION:Connector pin insertion passages 3b are provided to the printed circuit board 3, which is fixed to the terminal of the electromagnetic coil wound around a coil core 1a through a frame 1 by soldering, at the positions corresponding to the connection pins (4a', 4b'...) of connectors (4a, 4b...) for connecting the relay cable 9 from a head driving circuit board (not shown in a drawing) and the printed circuit board 3 while conductor patterns 3d are formed up to the connector pin insertion passages 3b corresponding to drive coil terminal parts 2a and one or a plurality of the connectors (4a, 4b...) are arranged on the printed circuit board 3 corresponding to the number of needles. Therefore, the printed circuit board 3 can be miniaturized and, as a result, an impact dod head can be miniaturized and assembling properties are also enhanced.

摘要： PURPOSE:To realize a magnetic loop from three surfaces forming a first yoke cutout part to a printing lever fulcrum part as well as from the side surfaces of a second yoke leg part to printing lever side surfaces to improve an energy conversion efficiency to a great extent by using a first and second yoke structure. CONSTITUTION:A first yoke plate 13 integrally made of a magnetic material is disposed on a wear-resistant member 12 and provided with a plurality of U-shaped cutout parts 13a on the peripheral part thereof. A second yoke 14 is provided with a plurality of leg parts 14a which are integrally made of a magnetic material so as to be integral at a base part 14b. Magnetic fluxes generated by the excitation of drive coils 8 are transmitted to the first yoke through frame cores 7, a peripheral wall 5, and the wear-resistant member 12. Parts of the magnetic fluxes from the first yoke are transmitted from the U-shaped cutout forming surfaces 13a on the peripheral part to printing lever fulcrum parts 11a, and the remaining fluxes are transmitted from cutout-free surfaces to the second yoke leg parts to be transmitted from the side surfaces of the leg parts to the printing lever side surfaces. In this manner, the magnetic fluxes converge on an armature part to realize a magnetic circuit of high efficiency.

摘要： PROBLEM TO BE SOLVED: To attain cost reduction of a paper sheet carriage device provided with an automatic reversal function of a paper sheet.
SOLUTION: Rotation of a drive pulley MP of a motor is transmitted to a carriage roller 51 when a first planetary gear 13 is engaged with a gear 16, or a secondary planetary gear 14 is engaged with the gear 16 through an idle gear 15. The carriage roller 51 constantly rotates in a normal rotation direction C in accordance with rotation of the motor independent from the rotation direction of the motor. A locking member 17 keeps such a state that a first planetary rocking body 12 is locked at a rocking position in which the second planetary gear 14 is engaged with the gear 16 through the idle gear 15 with the locking member 17 fitted on a projection 122 of the first planetary rocking body 12. A paper sheet carried to a carriage path EC presses a lever 171 to rock the locking member 17, thus releasing locking of the first planetary rocking body 12 by the locking member 17.

摘要： PROBLEM TO BE SOLVED: To improve in power efficiency by suppressing idling as much as possible of reverse rollers in a double-sided printer in which the drive power of a paper transport roller is utilized to drive the reverse rollers.
SOLUTION: In a printing apparatus, a front-surface printing is performed by joining a paper-feed transport path 71 and a reverse transport path 81 having reverse rollers 82 and 83, in front of a print head 40 and sending a sheet S forward to pass, by means of the paper transport roller 20 from the paper-feed transport path 71 to a print head part of a common transport path 72, following the joint juncture, and then after the sheet S is sent backward and reversed at the reverse transport path 81, the back surface is printed. The double-sided printer is equipped with a power transmission mechanism to drive the reverse rollers 82 and 83 by utilizing the drive power of the paper transport roller 20. The reverse rollers 82 and 83 are driven by means of the power transmission mechanism after the start of the reversal operation when the front-surface printing is completed.
