1. A manual operation system for a machine having a plurality of operating sections, comprising:
- selection switch means, including selection switches each associated with a corresponding one of the plurality of operating sections, for providing output signals corresponding to actuation states of said selection switches; and
a numerical control apparatus for controlling the machine, said numerical control apparatus including;
switch discriminating means for monitoring said output signals and for discriminating an actuation state of individual ones of said selection switches;
memory means for storing a plurality of manual operation programs;
controlling means for controlling an associated one of the plurality of operating sections in accordance with an operating position of said associated one operating section and a manual operation program corresponding to said operating position and in the same manner as a corresponding automatic operation program;
initiating means for initiating operation of said controling means and for specifying said corresponding manual operation program on the basis of an operating position of said associated one operating section and in accordance with said discrimination of said switch discriminating means.

Abstract
Disclosed is a manual operation system for a machine controlled by a numerical control apparatus (1). The same operation pattern as in an automatic operation mode can be manually performed according to the manual operation system.
When a programmable controller central processing unit (6) determines that a manual instruction from selection switches (33a-33g, 34a, 34b) is kept enabled, the machine is controlled according to the manual operation program including a predetermined portion of the automatic operation program, thereby executing the same operation as in the automatic mode from the current position.

5. A manual operation system for an injection molding machine having a plurality of servomotors for driving a plurality of axes of the machine, at least one of the plurality of servomotors associated with at least one of the plurality of axes being operable in plural operating directions, comprising:
-
a main operation panel means mounted on the injection molding machine, including selection switches each corresponding to an associated one of the plurality of axes and including at least one direction selection switch for selecting an operating direction to which the at least one servomotor is to be operated along the at least one axis, for providing output signals corresponding to actuation states of said selection and direction switches; and a numerical control apparatus for controlling the servomotors, said numerical control apparatus including; switch discriminating means for monitoring said output signals and for discriminating an actuation state of said selection and direction switches of said main operation panel means; memory means for storing a plurality of manual operation programs; controlling means for performing multi-stage control of the at least one axis in the corresponding one of the plural operating directions, in accordance with an operating position in the at least one axis and in accordance with a series of instructions respectively stored in a plurality of addresses of said memory means corresponding to one of said manual operation programs; initiating means for initiating operation of said controlling means and for specifying said series of instructions on the basis of an operating position in the at least one axis and in response to said discrimination of said switch discriminating means.
