Abstract: A method for transferring an image from a color photograph onto an object having multiple curved surfaces utilizes a backing sheet to protect the object from the heat required for thermal transfer. The object is disposed in a press assembly near the backing sheet so that the image attached to the backing sheet may be aligned with the target surface on the object. Then, the backing sheet is moved toward the target surface so that the image contacts the target surface at a desired position. The backing sheet is further pressed against the object to deform the target surface until it is substantially flat. Heat applied to the backing sheet and the image then causes the pigment contained in the image to be transferred onto the target surface to create a mirror image without damaging the object. When the backing plate is removed, the object will substantially regain its original curvature.

Abstract: The present invention discloses a data switch for a Bi-Tronics printer that keeps the Bi-Tronics printer in the use of data switch by adding a controller circuit which provides simulating responding signals to a disconnected computer. When the data switch is turned to different position, that is, the Bi-Tronics printer is in fact disconnected with the computer, a pseudo signal will be provided by the controller circuit to deceive the computer that the printer is still connected. Therefore, the driver of the Bi-Tronics printer in computer could not detect the abnormal condition of the Bi-Tronics printer, so that, the error massage will not appear on the screen and the data switch could still function properly between the computer and the Bi-Tronics printer without interrupting the user.

Abstract: The printing apparatus has a holding cylinder in which communication holes for communicating an external portion and an internal portion are made and a transfer pad which covers the outer surface of the holding cylinder at ordinary times in a detachable manner, expands upon pressure being applied via the above communication holes when the interior of the holding cylinder is pressurized, and contracts and returns to its original state when the pressure is released. Ink is adhered to the outer surface of the expandable/contractable transfer pad. The transfer pad is inserted in the contracted state into a cylindrical hole of an object to be printed. Pressure is applied from the inside of the transfer pad to cause it to expand and cause the outer surface of the transfer pad to press against the inner surface of the cylindrical hole and thereby transfer the ink adhered to the outer surface of the pad to the inner surface of the cylindrical hole.

Abstract: To prevent effective print speed from being lowered, a counter is provided for each of a plurality of print hammers. A number of times a print hammer is driven during one print phase having a predetermined period of time is counted by the counter. The counted value is compared with a reference value, and when the counted value has reached the reference value during the print phase, driving of the print hammer is halted until the end of the print phase. A reference value is changed based on the number of times the print hammer is driven during a previous print phase immediately before the present print phase. The reference value represents an allowable number the print hammer can be driven during each of successive print phases.
