Title: Cutting device of running circular saw machine
Inventor: SUGIYAMA KYOICHI
IPC: B27B5/20
Filed: 1990-04-13
Abstract: PURPOSE:To enable the projection degree corresponding to the thickness to be set automatically without measuring the thickness of a working material and the projection degree of the circular saw each time by detecting the blade tip of the circular saw by means of detecting switches provided on a pressing board side, and setting the projecting position of the circular saw by the detected signal. CONSTITUTION:After a working material W is supplied onto a table 1, a pneumatic cylinder 21 is actuated for extension-operating a piston rod, so that a pressing board 20 comes down so as to press-fix the working material W. At this time, detecting switches S (a, b) provided on attaching stays 23 also operate in the same direction and thus the position is specified in accordance with the thickness of the working material W. Subsequently, a pneumatic cylinder 11 acts to extend the piston rod 12 and, in consequence, a circular saw 9 is operated in the projecting direction. The operation degree of the circular saw 9 is set by means of a stopper lever 17 corresponding to an attaching table 7. In the projecting condition of the circular saw 9, when the detecting switch S is in the condition of non detection, the stopper lever 17 operates upward by the rotation of an electric motor 18, so that the attaching table 7 rotates and thus the circular saw 9 is forwarded in the projecting direction. And, the projection degree is corrected thereby and, therefore, the circular saw 9 can be set at an appropriate position.

Filed: 1991-04-30
Abstract: PURPOSE:To prevent a photosensitive drum from being adversely affected by external light and dust, etc., and to enhance the degree of freedom in the case of setting the height of a boundary part by separating the boundary part which forms a paper feeding port and a paper ejection port from the rotary shaft line of the photosensitive drum by a specified distance. CONSTITUTION:It is desirable to combine the abutting part of an upper casing 24 and a lower casing 25 in a shiplap state. This is because light is prevented from getting into a device main body 2 from the abutting part of both casings. Then, the paper feeding port 26 and the paper ejection port 21 are formed at the boundary part between both casings by the notch 24a of the upper casing 24 and the notch 25g of the lower casing 25. Since the boundary part between both casings is positioned lower than a water surface including the rotatry shaft line R of the photosensitive drum 42, the external light and the dust, etc., from the aperture parts of the paper supply port 26 and the paper ejection port 21 are difficult to reach the photosensitive drum 42.
