Abstract
A mechanical apparatus having a plurality of mechanisms each independently operable and a system for controlling the mechanisms by a program. For at least one of the mechanisms, the controlling system is caused by the program to produce an operation start signal with a timing earlier than the proper operation timing. The signal is fed to a time-adjustable delay mechanism, which in turn initiates the operation of the mechanism.
Claims5
In a mechanical apparatus having a plurality of mechanisms each of which is independently operable, means for driving the respective mechanisms, and mechanism starting means for starting the operation of at least one of the mechanisms in the midst of an operation of the mechanical apparatus, a means for controlling the timing of operation of said one of said mechanisms, said controlling means comprising:
- a program controlling device for said mechanical apparatus having a timer means set for a predetermined time which is set in the program of said program controlling device as a numerical data and which is such as to end at a time earlier than the time for the proper operation of said mechanism starting means;
- apparatus starting means for starting the operation of the mechanical apparatus;
- timer starting means connected between said apparatus starting means and said timer means for starting the operation of said timer means at the time of the start of operation of the mechanical apparatus;
- starting signal generating means forming part of said program controlling device and operated by said timer for generating a starting signal for said one of the mechanisms when said predetermined time has elapsed;
- and
- delay means connected between said starting signal generating means and said mechanism starting means for receiving said starting signal for starting the operation of said mechanism starting means and supplying it to said mechanism starting means after a time delay, said delay means including an adjusting means for adjusting the delay time.
A copying apparatus having a movable photoconductive member, means for forming an image on a surface of the photoconductive member, means for transferring the image on the surface of the photoconductive member to a sheet of copying paper which is fed past said transferring member by a paper feeding means, means for temporarily stoping the copying paper at a position upstream of the transferring means, and restarting means for restarting the operation of feeding the copying paper from the stopped position thereof toward the transferring means, means for controlling the timing of the operation of at least the restarting means, said controlling means comprising:
- a program controlling device for said copying apparatus having a timer means set for a predetermined time which is set in the program of said program controlling device as a numerical data and which is such as to end at a time earlier than the time for the proper operation of said restarting means;
- copying apparatus starting means for starting the operation of the copying apparatus;
- timer starting means connected between said copying apparatus starting means and said timer means for starting the operation of said timer means at the time of the start of operation of the copying apparatus;
- restarting signal generating means forming part of said program controlling device and operated by said timer for generating a restarting signal for said restarting means when said predetermined time has elapsed;
- and
- delay means connected between said restarting signal generating means and said restarting means for receiving said restarting signal and supplying it to said restarting means after a time delay, said delay means including an adjusting means for adjusting the delay time.
