Claims

[Claims for Utility Model Registration] 1. A head equipped with an electric motor M□ that drives vertical and horizontal sides and both sides guided by a column erected on a base having a vise mechanism for fixing a workpiece. Department,
Electric motor M2 that drives a screw shaft installed parallel to the column
Accordingly, in a tenon removing machine that can be automatically raised and lowered, a run switch and a stop switch are provided to start and stop the electric motor M A detector and an upper limit detector are provided, and electric signals from these switches and detectors cause the motor M1? A tenon removal machine characterized by being equipped with a control circuit for controlling the operation and stopping of the pigeon. 2. The tenon removal machine according to claim 1, which is a registered utility model and is equipped with a control circuit having a delay circuit that operates the electric motor M1 when the operation switch is operated, and operates the electric motor pigeon after a preset time. . 3. If the stop switch is operated while the head section is lowering, the power to the motor M□9M2 is cut off, and then the power is turned on to reverse the motor M2 for a short time, and the stop switch is operated while the head section is rising. Utility model registration claim 1, which is equipped with a control circuit having a timer circuit and a rotation direction switching circuit that cuts off the power to the electric motor pigeon when operated, and then turns on the electric motor M2 so as to reverse it for a short time. Mortising machine. 4 Receive an electrical signal when the lower limit detector operates,
Detecting that the head has reached the lower limit position, the electric motor M
