摘要： PROBLEM TO BE SOLVED: To provide a mounting structure for inserting a conductive band bar that has an improved working efficiency and is long without dividing it. SOLUTION: A plurality of conductive band bars are inserted into an enclosure 2 outside the enclosure for tentative assembly, and are clamped and fixed by a conductive band bar clamping tool 8 such as a binding band. The tentatively assembled conductive band bar 1 is inserted into the enclosure 2 through an opening 9 of an enclosure longer direction edge part plate 3 and an opening 10 of the screening plates 4a and 4b of the inside of the enclosure 2. After the insertion, the conductive band bar 1 is holded by a conductive band bar support tool and then is connected to, for example, a control equipment and a terminal block in the enclosure 2.

摘要： PURPOSE:To easily mount and disassemble an endless belt by slight force by providing a unit wherein a compression spring is clamped and fixed to a spring receiving bracket formed into a horizontal U-shape in a compressed state by a screw. CONSTITUTION:A compression spring 2' is received in a spring receiving bracket 12 in a compressed state by the spring killing screw 13 fitted in the thread cut in a screw plate 14. When an endless belt tensile apparatus is mounted on a main body frame 8, an endless belt 1, a tension pulley 6 and tension pulley shaft 11, since the compression spring 2' is compressed by the spring killing screw 13, said apparatus can be easily set with allowance. The tension pulley shaft is hooked with the hood part of the spring receiving bracket 12 and, thereafter, the spring killing screw 13 is slowly loosened to put the killed com pression spring 2' to practical use and tension force is applied to the endless belt 1. As a result, since the spring force giving tensile force to the endless belt is killed by the spring killing screw when the endless belt is mounted and detached, the endless belt can be easily assembled and disassembled.

摘要： PURPOSE:To miniaturize the display of a computer terminal equipment, to integrally form it and to reduce the twist and the rub of a cable between a display having a swivel and a tilt mechanism, and a controller. CONSTITUTION:A signal cable 4 and a power cable 5 are made to pass through the rotation center part of a slider 2 connecting the display 1 and the controller 3 through the notch part of a freely turnable cable guide 7, and they are guided to the internal cable storage guide 8 of the controller 3. Thus, the twist and the rub of the cable connecting the display and the controller at the time of operating the swivel and the tilt of the display are reduced.

摘要： PURPOSE:To prevent shading of a printing character from being generated by varying preparation of a gap between a print head and a platen linearly in one direction without rotating a support rail by a method wherein rotation of an eccentric cam fitted to the support rail and a moving direction of the support rail are forced with a fitting hole of a frame. CONSTITUTION:A print head 1 moves in the same way as movement of a support rail 6, and the support rail 6 is varied forcively in one direction in an oval hole of a frame 5 supporting a constant support rail 6 by rotation of eccentric cams at both end parts. The cam 7 is pushed against a roller 8 with a spring 9, and only the cams are simultaneously rotated with gear parts of left and right cams 7. Since the print head 1 can move in a straight line to a paper surface, each dot composing a character, i.e., a gap between each wire of the print head 1 and the paper surface can be kept at a specific value according to thickness of paper, and both high speed printing and high printing quality can be realized without generating shading of the character.

摘要： PURPOSE:To cut paper easily on a printer by using a simplified structure in which a cutter and paper bail roller are formed into an integrated unit and fixed to a frame. CONSTITUTION:A paper bail roller 5 is placed at a cutter 8, both roller and cutter are integrated as cutter unit, and the paper bail roller is fixed to a platen 2 so as to be always in contact with the platen. When paper is initialized in a printer constituted in this manner, the correction of slackening of the paper is performed by a control system, where the dimension of the tip of the paper is set to a dimension (H-B) somewhat shorter than the dimension H from the center of a print head 1 to the tip of the edge of the cutter and thereafter the B-dimension is let out.

摘要： PURPOSE:To widen the between the nose of a printing head and a platen even in such a state that a power supply is cut off by providing a guide part to a part of the guide rail supporting the carrier loaded with a printing head so as to widen the gap between the nose of the printing head and the platen. CONSTITUTION:Continuous paper passes through a gap G from the front of a printer to be set to a tractor 9. When single continuous paper is set to be printed, the thickness of the paper is detected and the gap G is set to proper quantity by rotating an eccentric guide rail 3 by a motor. When a power supply is cut off after printing, since the gap G is set to the quantity proper to the single paper, when multilayer continuous paper, for example, five-layer continuous paper is ready to set, the paper can not pass through the gap G because the gap G is smaller than the thickness of the five-layer paper and the paper becomes impossible to set. When a guide part 4a is provided outside the printing moving range of the carrier of a guide rail 4, the bearing 5 present within a printing range moves like a bearing 5' outside the printing range and the carrier 2 is rotated around the guide rail 3 in the counterclockwise direction and, therefore, printing head 1 rises to widen the gap G.
