Printer device, printing method, and program for outputting an exposure start signal without requiring a film detection device

A printing method of a printer device including a loading chamber into which a film cartridge in which a film including a developer pod filled with a developer is housed is to be loaded, an exposure head device that is disposed to face a photosensitive surface of the film discharged from the film cartridge and exposes the film to light, a spreading roller that splits the developer pod of the film to spread the developer to the film, and a transport roller that transports the film, the printing method comprising:

• measuring a change in load occurring in a case where the film enters at least the spreading roller or the transport roller by a load measuring device of the printer device;
• and
• outputting an exposure start signal to the exposure head device on the basis of a measurement result of the load measuring device, to cause the exposure head device to start to perform exposure by a processor of the printer device,
• wherein the processor controls the exposure head device on the basis of a measurement result of the load measuring device,
• wherein the load measuring device includes a rotary encoder device, the rotary encoder device is provided at an end portion of a rotating shaft of the transport roller and outputs a pulse signal according to a rotation of the transport roller, and
• wherein the processor outputs an exposure start signal to the exposure head device on the basis of the measurement result of the load measuring device and causes the exposure head device to start to perform exposure, and the processor outputs the exposure start signal on the basis of a pulse time.

A non-transitory, computer readable tangible recording medium which records thereon a program causing, when read by a computer, the computer to perform a printing method with a printer device including a loading chamber into which a film cartridge in which a film including a developer pod filled with a developer is housed is to be loaded, an exposure head device that is disposed to face a photosensitive surface of the film discharged from the film cartridge and exposes the film to light, a spreading roller that splits the developer pod of the film to spread the developer to the film, and a transport roller that transports the film, the method comprising:

• measuring a change in load occurring in a case where the film enters at least the spreading roller or the transport roller, using a load measuring device of the printer device, and
• outputting an exposure start signal to the exposure head device on the basis of a measurement result of the load measuring device, to cause the exposure head device to start to perform exposure by a processor of the printer device,
• wherein the processor controls the exposure head device on the basis of a measurement result of the load measuring device,
• wherein the load measuring device includes a rotary encoder device, the rotary encoder device is provided at an end portion of a rotating shaft of the transport roller and outputs a pulse signal according to a rotation of the transport roller, and
• wherein the processor outputs an exposure start signal to the exposure head device on the basis of the measurement result of the load measuring device and causes the exposure head device to start to perform exposure, and the processor outputs the exposure start signal on the basis of a pulse time.
