Claims (1)

[Claims for Utility Model Registration] A window in which the raising and lowering operations of the window are directed in opposite directions, and by a two-stage operation in which the first stage is manual operation and the second stage is automatic operation. It has two non-locking switching contacts that can be switched to the power side or the ground side and are normally connected to the ground side, in order to switch the lifting operation of the operation unit and the drive motor for automatically lifting the window glass, and only one of them is connected to the power side. a switching contact that enables operation in one direction, either upward or downward, when the window operating section is in the opposite direction; and a switching contact that switches the switching contact on the corresponding side to the power supply side based on one-step or two-step operation of the window operating section in both directions. and a holding means that controls the switching contact driving section and maintains the connection state of the switching contact to the power supply side, and detects the two-step operation of the window operating section to put the holding means into an operating state and performs a predetermined operation. The switching contact on the operation side remains connected to the power supply side until the activation release signal is input, and the switching contact is held on the power supply side when the fully closed or fully open state due to the rising or falling of the window glass is detected. an auto control circuit having an opening/closing detection circuit that switches the window to the ground side, and an operation detection means that detects the operation state of the window operation section, and when the window operation section is operated to the other side while the window operation section is being operated automatically to the other side. The switching contact is switched to the power supply side, and one switching contact that is on the auto operation side is held on the power supply side for a first predetermined time while the operation continues, and the holding state is released after the first predetermined time has elapsed. , when the operation on the other side is stopped during the first predetermined time period, both switching contacts are set to a non-holding state, and the operation of the window operation section on the other side is stopped during the second predetermined time period after the holding is released. An automatic release control circuit that sends an activation release signal to the automatic control circuit so that the other switching contact is in a non-holding state when the power window is stopped.
