An encoder signal processing device, a printer, a printer-equipped imaging apparatus, and an encoder signal processing method that can remove the effect of a noise signal mixed with an encoder signal and favorably deal with a case where an original pulse signal is lost from the encoder signal are provided. An effective detection period setting unit 523 sets an effective detection period for detecting a subsequent pulse signal, each time a pulse signal detection unit 522 detects a pulse signal from an encoder signal. The pulse signal detection unit 522 detects the pulse signal only within the set effective detection period. In a case where the pulse signal detection unit 522 does not detect the pulse signal within the effective detection period, a pulse signal generation unit 524 generates the pulse signal after the effective detection period.

In a case that accommodates an instant film, an exposure opening portion, a discharge port, and a claw opening portion are provided. The exposure opening portion is light-shielded by a film cover that is disposed to overlap the instant film. The film cover includes a notched portion connected to the claw opening portion. In a case where the film cover is not removed in use, a claw inserted through the claw opening portion is moved within a range of the notched portion. In a case where the film cover is removed in use, the claw is moved within a range that exceeds the range of the notched portion.

In a case that accommodates an instant film, a first claw opening portion and a second claw opening portion for inserting a claw into the case are provided. In a film cover that light-shields an exposure opening portion of the case, a notched portion continuous to the first claw opening portion is provided. In a case where the film cover is not removed in use, the first claw opening portion is used, and in a case where the film cover is removed in use, the second claw opening portion is used. By using the first claw opening portion, it is possible to avoid contact of the claw and the film cover, and to discharge only an instant film in a state where the film cover is mounted.

A protective means has a pouch-like structure, comprising an orifice for inserting X-ray imaging media in the protective means. In connection with the protective means there is also a closing means, which is arranged to close the orifice. Also in connection with the protective means there is a fastening means for fastening a closing means to the pouch-like structure of the protective means so that upon fastening the closing means the fastening means is arranged to be located on both sides of the orifice.

A printer unit has a film pack room into which any one of a first instant film pack or a second instant film pack is loaded, an exposure head, and a controller. The second instant film pack is aligned in the film pack room so as to be shifted to the one side.
