IPC: B41J3/36
Filed: 1989-04-24
Abstract: PURPOSE:To obtain a mechanism occupying a small space and to realize a low cost by a method wherein a tape feeding and a tape cutting are performed with one motor by switching the rotating direction of the motor. CONSTITUTION:When a motor 1 is actuated to be rotated in a direction of an arrow A, this rotation is transmitted to a sun gear 6 through gears 3, 4. Then, the sun gear 6 rotates in a direction of an arrow C, whereby a planet gear 8 engages with a gear 14 to transmit the drive force of the motor to a tape feed mechanism 20. The rotation of a drive roller 11 in the tape feed mechanism causes a tape 50 to be fed in a direction of an arrow E. When the printed tape 50 is further fed to a predetermined cut position, the motor 1 is rotated reverse. This rotation causes the sun gear 7 to rotate in a direction of an arrow D, whereby the planet gear 8 engages with a gear 28 to rotate a gear 21 integrally formed with a cutter lever in a direction of an arrow F, and a cutter edge comes into collision with a pad 26 to cut the tape 50. In this manner, a low-cost tape feeding and cutting device is made available.

Title: Apparatus for detecting position of body
Inventor: SUZUKI SUSUMU
IPC: G06F3/03
Filed: 1987-04-27
Abstract: PURPOSE:To detect the position of a body, by operationally processing the light blocking phenomenon, which is generated by scanning one laser beam by a rotary mirror to reflect the same from the reflecting part provided to the peripheral surface of a detection area and projecting the reflected beam on the body, and the light blocking phenomenon detected by a beam receiving means. CONSTITUTION:The beam path of the laser beam L of a beam emitting element LD changes by the angle of rotation of a mirror 3. Beam L1 is reflected by the reflecting mirror 4 provided to the peripheral surface of an area 1 to reach a beam receiving element group PD 3 and beam L2 reaches a beam receiving group PD 4 and beam L3 directly goes to a beam receiving element group PD 4 but it is blocked by a body 5 and groups PD 3, 4 are arranged at the predetermined positions on the peripheral surface of the area 1 at arbitrary angles in an arbitrary number so as to continuously output the sum signal of the groups during the projection of the beams L1-L3. The laser beam L1 is blocked by the body 5 in the area 1 and the sum signal of a terminal 6 reduces (first beam blocking phenomenon). The laser beam L3 is blocked so as to provide time difference from the laser beam L1 and the sum signal of the terminal 6 reduces (second beam blocking phenomenon). The position of the body can be calculated by performing operational processing using both output signals corresponding to each other and, by this constitution, the number of beam emitting and receiving elements are reduced to make it possible to detect the position of the body.

Thereby, both the meat cylinders (2A) and (2B) alternately repeat the above-mentioned suction and discharge operations. Since a scraping member 42 in a hopper 4 intermittently rotates along the inner surface of the hopper body 41 by operation of an air cylinder 46 during operation of the cylinders (2A) and (2B), the raw material sticking to the inner surface so that air may be prevented from being sucked into the meat cylinders in preparation for suction of the raw material into the meat cylinders (2A) and (2B).
