摘要： PURPOSE:To easily obtain a synthetic image with simple constitution by providing a switching means to switch and output a signal from an image memory means and the signal from a still image input processing means in accordance with a synthetic control signal. CONSTITUTION:A memory control means 30 stores a first image signal based on a first synchronizing signal in an image memory means 9. A synthetic control signal generating means 24 generates the synthetic control signal to select and set area where both images are synthesized, and supplies the signal for the switching means 15. Then a third image signal is supplied to the still image input processing means and simultaneously supplied to a synchronous signal dividing means 28. Based on the divided synchronous signal, the control means 30 controls the signal so as to read out the first image signal from the image memory means 9. Thus, the switching means 15 is activated in accordance with the synthetic control signal and allows the first image signal from the image memory means 9 to be synchronized with the third image signal from the still image input means. Consequently, the synthetic image print is obtained with simple constitution.

摘要： PURPOSE:To greatly shorten the time required for recording of one sheet including the time for delivery of the same by a method wherein fixing of the recording sheet by a chuck is released immediately before starting of the recording for the third color, and sheet delivery is made at same time as the execution of recording for the third color. CONSTITUTION:Immediately before starting of the printing for the third color, a platen roller 1 is rotated under a recording sheet-carrying mode, then a motor 9 stops by operation of a sensor 80 and a second motor 44 starts operation. Thereby shifting is made from the recording sheet-carrying mode to a recording sheet delivery mode. At this time, a slider 54 moves, and a stand 25 for unwinding reel is fixed with a lock arm 26 under the recording sheet delivery mode, while a platen locking arm 58 is released together with the release of the recording sheet-carrying mode, and a slide gear 25 is engaged with a platen gear 8 in a state the same as that of a printing mode. A K-arm 60 swings along a slit 54f for the swing of the slider 54, and as a chuck arm 5 and one end 60b of the K-arm make contact each other, the chuck arm 5 comes up, separating from the circumference of the platen roller 1, and thereby fixing applied to a recording sheet 3 is released.
