Patent number: 6564013Abstract: First and second driving systems are driven by a first motor via first and second planetary mechanisms through motor rotation in first and second directions, respectively. A third driving system is driven by the second planetary mechanism through motor rotation in the first direction. A switching mechanism switches a transmission path for the motor driving force by inhibiting one of the first and second planetary mechanisms from revolving, and causes the other of the first and second planetary mechanisms to transmit the driving force through a transmission path selected by the switching. First and second restraint members of the first and second planetary mechanisms, respectively, restrain the respective mechanisms from revolving simultaneously by inhibiting engagement of the first and second planetary mechanisms with the second and third driving systems, respectively.Type: GrantFiled: October 15, 2001Date of Patent: May 13, 2003Assignee: Canon Kabushiki KaishaInventor: Shoji Kaihara

Patent number: 6529688Abstract: There is provided a camera which is compact in size and inexpensive even with the use of two motors, which allows relevant mechanisms to be laid out freely to thereby simplify motor controlling sequences, and which allows the user to quickly perform preliminary winding of a newly loaded film after film rewinding to thereby minimize the effects of film replacement during photographing. A first motor is used to drive a film winding driving system and a film rewinding driving system. A switching mechanism selectively switches between a winding state in which a driving force of the first motor can be transmitted to the film winding driving system, and a rewinding state in which the driving force of the first motor can be transmitted to the film rewinding driving system. A second motor is used to drive the switching mechanism for selective switching between the winding state and the rewinding state.Type: GrantFiled: July 31, 2001Date of Patent: March 4, 2003Assignee: Canon Kabushiki KaishaInventors: Shoji Kaihara, Shigeru Yamagami
