Window covering cutting apparatus

A window covering cutting apparatus for cutting a window covering, the window covering cutting apparatus comprising:

• a supporting base, for placing the window covering;
• a mounting base, neighboring to the supporting base;
• a cutting device, disposed on the mounting base for cutting the window covering;
• a size positioning device, comprising:
• a manual operating member;
• a limit assembly, configured to be connected to the manual operating member and drivable by the manual operating member to move with respect to the mounting base, the limit assembly being provided to be abutted against by at least a first end of the window covering;
• and
• a position detecting device, configured to detect a position of the limit assembly and generate a position detecting value corresponding to the position of the limit assembly;
• and
• a portable device, comprising:
• an input device, configured to capture information comprising a mounting mode for mounting the window covering, cutting size information, and identification information of the window covering;
• an output device;
• a storage device, configured to store product information of the window covering;
• and
• a signal processing circuit, electrically coupled to the input device, the output device, the storage device and the size positioning device;
• wherein after the input device captures the identification information of the window covering, the signal processing circuit obtains the product information of the window covering from the storage device according to the identification information of the window covering, and then generates adjusted position information and target position information according to the product information, the mounting mode, the cutting size information and the position detecting value, after which the signal processing circuit configures the output device to graphically display at least the adjusted position information;
• the target position information corresponds to a correct cutting size to which the window covering will be cut;
• the adjusted position information comprises at least one of current position information of the limit assembly and a comparison result of the current position information and the target position information;
• the manual operating member is manually adjusted according to the adjusted position information to move the limit assembly until the adjusted position information substantially equals the target position information, wherein whether the adjusted position information substantially equals the target position information is visually recognizable from the output device;
• after-which the manual operating member has been manually adjusted to move the limit assembly until the adjusted position information substantially equals the target position information, the signal processing circuit configures the cutting device to cut the first end of the window covering.
