Abstract
An apparatus for controlling the transmission of power from a motor to a number of devices at selected times utilizes a single trigger mechanism which is operated at predetermined times in an operating cycle. The trigger mechanism controls a plurality of clutch mechanisms which transmit the power to the devices. The clutch mechanisms are locked against operation at times when they are not selected for operation.
Claims22
An apparatus for controlling the transmission of power from a continuously operating motor to at least a first device and a second device during an operating cycle, the apparatus comprising:
- means for providing at least one first trigger signal and at least one second trigger signal during the operating cycle;
- trigger means responsive to each first trigger signal at first predetermined periods of time in the operating cycle and to each second trigger signal at second predetermined periods of time in the operating cycle;
- first control means coupled to the motor and responsive to the trigger means for transmitting said power to the first device at the first predetermined periods of time;
- second control means coupled to the motor and responsive to the trigger means for transmitting said power to the second device at the second predetermined periods of time and including cam means and lever means;
- said lever means operable in response to the cam means at one of the first predetermined periods of time for preventing the transmission of said power to said second device and at one of the second predetermined periods of time for permitting the transmission of said power to said second device.
A printer having at least a first device and a second device and an apparatus for controlling the transmission of power from a continuously operating motor to at least the first device and second device during an operating cycle, the apparatus comprising:
- means for providing a first trigger signal and a second trigger signal during the operating cycle;
- trigger means responsive to each first trigger signal at first predetermiend periods of time in the operating cycle and to each second trigger signal at second predetermined periods of time in the operating cycle;
- first control means coupled to the motor and responsive to the trigger means for transmitting said power to the first device at the first predetermined periods of time;
- second control means coupled to the motor and responsive to the trigger means for transmitting said power to the second device at the second predetermined periods of time and including cam means and lever means;
- said lever means operable in response to the cam means at one of the first predetermined periods of time for preventing the transmission of said power to said second device and at one of the second predetermined periods of time for permitting the transmission of said power to said second device.
