    • A printing apparatus having shorter length in the longitudinal direction and a dust-protecting feature is disclosed. The printer includes a main frame, a subframe assembly, first and second pulse motors each have a reduction gear drive mechanism, a thermal head, a platen roller, a rotary blade, and a stationary blade. The first motor for driving the platen roller and the second motor for driving the rotary blade are disposed between two side plates provided one on each end of the main frame. The reduction gear drive mechanisms are substantially sealed and disposed inside the corresponding side plates. Two pulleys and a timing belt are provided outside each of the side plates.

    • A printer apparatus is disclosed that includes a printer unit, a first chassis, and a second chassis that is arranged to open/close through rotation. The printer unit includes a thermal head, a first module having a motor, and a second module having a platen roller and a rotating body. The first chassis includes a heat sensitive paper roll accommodating portion and a mount portion to which the first module is mounted. The second chassis includes mount portions to which the second module and a printed paper roll shaft are mounted, a printed paper roll accommodating portion, and a rotation transmitting mechanism. When the second chassis is closed, the heat sensitive paper roll accommodating portion is closed, the second module is coupled to the first module, the rotating body is rotated by the motor, and the shaft is rotated by the motor via the rotating body and the rotation transmitting mechanism.

    • A hydraulic tensioner 10 includes a piston rod 12 slidably fitted in a cylinder 14 with a small gap or clearance therebetween, and a housing 16 containing the cylinder 14. A ball seat 20 is press-fitted in an end of the cylinder 14 opposite to the piston rod 12 so as to define within the cylinder 14 a high pressure oil chamber 21. The housing 16 has a partition wall 26 at a substantially central portion thereof. The cylinder 14 is loosely fitted in the housing 16 with its longitudinal portion extending forwardly from the partition wall 26. The partition wall 26 has an oil passage 32 having an inside diameter smaller than the outside diameter of the ball seat 20, so that the cylinder 14 and the ball seat 20 are in abutment with the partition wall 26 of the housing 16. A force tending to retract the piston rod 12 generates a pressure which acts on the partition wall 26 either directly via a spring 24 and the cylinder 14 or via the high pressure oil chamber 21 and the ball seat 20.
    • 液压张紧器10包括可滑动地装配在气缸14中的活塞杆12,其间具有小的间隙或间隙,以及容纳圆筒14的壳体16.球座20压配合在气缸14的与 活塞杆12,以在气缸14内限定高压油室21.壳体16在其基本中心部分具有分隔壁26。 气缸14松动地装配在壳体16中,其纵向部分从分隔壁26向前延伸。分隔壁26具有内径小于球座20的外径的油通道32,使得气缸 14和球座20与壳体16的分隔壁26邻接。趋向于缩回活塞杆12的力产生直接经由弹簧24和气缸14或通孔的作用在分隔壁26上的压力 高压油室21和球座20。
