Publication number: 20120205861Abstract: When a sheet cassette (10a) is pulled out of the body of an image forming apparatus (100), winding pulleys (40a and 40b) are rotated by the weight of a lift plate. An idle gear (47) also is rotated by a predetermined amount, so that the engagement portion (47b) thereof engages with a second arm portion (50c) of a torsion spring (50). Since a force exerted by the torsion spring (50) is set greater than the force that rotates the idle gear (47) by downward movement of lift plate (30), rotation of the idle gear (47) and winding pulley (40a) is regulated, and thus the upper surface of lift plate (30) stops in a substantially constant position with respect to sheet supply opening portions (31a and 31b).Type: ApplicationFiled: December 16, 2011Publication date: August 16, 2012Applicant: KYOCERA MITA CORPORATIONInventor: Yoshihiro YAMAGUCHI

Patent number: 8161855Abstract: A cutting machine secures safety of a worker during movement of a head without lowering production efficiency. When moving a cutting head without cutting material to be cut upon a table, a moving truck and the cutting head are moved at a higher speed as compared with when cutting the material to be cut. If, when the moving truck and the cutting head are moving at high speed, a worker who is present upon the table intercepts either of light beams which are located in front of and behind a horizontal beam, then this movement speed is decelerated to a safe low speed, but the task of cutting the material is not interrupted. Subsequently, when the worker approaches the horizontal beam closer, and contacts a wire or a bar in the vicinity of the horizontal beam, movement of the moving truck and the cutting head is forcibly stopped.Type: GrantFiled: February 14, 2007Date of Patent: April 24, 2012Assignee: Komatsu Industries CorporationInventors: Yoshihiro Yamaguchi, Takahiro Iriyama, Satoshi Ohnishi
