A roller device includes a motor and a speed reducer inside a cylindrical roller or arranged coaxially, and an electronic apparatus includes a printer using the roller device. This roller device comprises a motor ( ) disposed on a cylindrical roller ( ), a sun gear ( ), planet gears ( ), a first inner tooth gear ( ) provided inside of the cylindrical roller ( ), and a second inner tooth gear ( ) provided inside of a bearing element ( ). The rotation of the bearing element ( ) is suppressed by a predetermined force. Thus the rotation of the motor ( ) is decelerated, and the cylindrical roller is rotated at a reduced speed. By rotating the bearing element with a force greater than a predetermined force, the cylindrical roller can be rotated manually.

A boom body comprises a boom front member, a boom intermediate member and a boom rear member. An arm-connection bracket is jointed to the boom front member and a vehicle body-mounting bracket is jointed to the boom rear member, thereby forming a boom. With this structure, a cross section of the boom body is less prone to be deformed and therefore, the plate thickness can be reduced, the rigidity of the boom body can be increased without mounting a cross section restraint material and the cross section of the boom is not deformed. Therefore, it is possible to reduce the boom in weight.

Method for making a boom of an excavator

An arm body of a working machine has a hollow and triangular cross-section. A bucket-connection bracket is jointed to one longitudinal end of an arm body, and an arm cylinder bracket is jointed to another longitudinal end of the arm body, thereby forming an arm. With the triangular cross-sectional structure, the arm body is less prone to deformation under the stress of a load. The improved triangular cross-sectional structure permits the plate thickness of the arm body to be reduced, and the rigidity of the arm body to be increased without mounting a cross-section restraint material in the arm body. The cross-section of the boom will not deform even though the plate thickness is reduced. Therefore, it is possible to reduce the weight of the boom and still prevent deformation of the boom under heavy load. A method of producing an arm body is efficient and simplified since a single sheet of metal may be formed into a triangular shape, with a single welded seem being formed at the seem between abutting edges of the metal material. The various corners of the triangular cross-section may be arc shaped or flat as is desired.

A printing apparatus has a small size that facilitates replacement of rolled paper, removal of jammed paper, etc., and alleviates the likelihood of a paper jam with a considerably simple structure. The printing apparatus comprises a rolled-paper holder (,), which is provided with a first holder (,) for use in carrying out printing on rolled paper (,), and a second holder (,) for use in setting the rolled paper (,). The rolled paper (,) is moved from the second holder (,) to the first holder (,) as a main body of the apparatus is shifted from a paper setting position to a printing work position, thereby facilitating the setting of the rolled paper (,) and removal of jammed paper, since the rolled paper (,) can be temporarily supported by the second holder (,) in order to provide sufficient work space when replacing the rolled paper (,) or removing jammed paper.

Printer

Printing device with cutter

A thermal line printer usable as a small output terminal. A printer body has a platen roller rotatably supported by a casing having side plates on either side thereof. A line-printing type thermal head is swingably supported by the printer body while being resiliently urged toward the platen roller. This arrangement allows the thermal head to be easily mounted on and dismounted from the printer body.
