IPC: B41J33/16
Filed: 1989-06-30
Abstract: PURPOSE:To prevent the loosening of a printing ribbon by meshing a drive gear with a bevel gear only when a motor is rotated forwardly to rotate the bevel gear in the reverse direction when the printing ribbon is drawn out and engaging a lock pawl with an intermediate gear only when a printing head is subjected to printing driving. CONSTITUTION:In the printing driving of a printing head 51, a motor 20 is reversely rotated so that a cam plate 33 rotates by about 200 deg.. This reverse rotation is stopped when a sensor plate 33b is detected by a sensor 35. When the cam plate 33 is rotated, a cam part revolves a lock pawl 29 to bring the same into engagement with an intermediate gear 13. Further, at the time of the reverse rotation of the motor 20, a cam gear 46 rotates by about 200 deg. by a rotary shaft 31 and, therefore, the first cam 46b detaches the locking of a lock roller 42 and the second cam 46a allows the printing head 51 to fall toward a platen 2. The motor 20 is again rotated forwardly to start printing and, at this time, the lock pawl 29 is engaged with the intermediate gear 13 and both of the delivery and taking-up of a printing ribbon R are not performed and the loosening of the printing ribbon R can be prevented.

IPC: A63F7/02
Filed: 1994-07-21
Abstract: PURPOSE:To prevent an erroneous operation by electromagnetic wave or exter nal light, and precisely detect the passing of game ball by making an operating piece pushed into a switch housing part when the ball passes the through-hole of a switch case, thereby a switch is brought into non-conductine stake and the passing of the ball is detected. CONSTITUTION:When no game ball passes a through-hole 30, one end of an operating piece 70 supported in the inner part of a switch housing part 40 is in the state capable of protruding into the through-hole 30, and the energizing force of a torsion spring 60 acts on the free end part on the other end to energize the operating piece 70 in the protruding direction. Both ends of the torsion spring 60 come into contact with a fixed pin 54 and a contact pin 53 in this state to hold the conductive state between the connecting terminals 51, 52 of a base 50. When a game ball passes the through-hole 30, the operating piece 70 is pushed against the energizing force of the torsion spring 60. Thus, one end of the torsion spring 60 is pushed in and separated from the contact pin 53 to bring the connecting terminals 51, 52 into the non-conductive state, thereby the passing of the game ball can be detected.
