In addition, in the present embodiment, optical pickocff 16 also can be arranged at guide member 33(Fig. 2) or demarcation strip 35(Fig. 2) on.Figure 21 means the stereogram that optical pickocff 16 is arranged to the embodiment of demarcation strip 35, and Figure 22 means the stereogram that optical pickocff is arranged to the embodiment of guide member 33.
In Figure 21, optical pickocff 16 demarcation strip 35 be arranged at can with upper layer side pallet 45 and the opposed position of lower layer side pallet 40 (upper surface side of the demarcation strip 35 of Figure 21).Similarly, in Figure 22, optical pickocff 16 guide member 33 be arranged at can with upper layer side pallet 45 and the opposed position of lower layer side pallet 40 (lower face side of the guide member 33 of Figure 22).
In any of the example shown in Figure 21, Figure 22, be preferably the luminous intensity that can adjust the illuminating part 16a of optical pickocff 16 as illustrated in the above-described 2nd embodiment.Particularly, be preferably in the situation that having or not paper to detect to lower layer side pallet 40 than make luminous intensity grow in the situation that having or not paper to detect to upper layer side pallet 45.
In addition, in the above-described embodiments, in a plurality of media storing portion, be in lower layer side pallet 40 and upper layer side pallet 45, to have or not paper to detect as prerequisite to recording the pallet of a side (sending paper side), but be not limited to this, also can detect the pallet that does not carry out the side that paper feeds and have or not paper.; the invention is characterized in, utilize an optical pickocff 16 to detect a plurality of pallets and have or not paper, in other words; an optical pickocff 16 is total at a plurality of pallets, can suitably set which pallet of detection and have or not paper, also has it to detect when the moment is.In addition, can only have or not separately the detection of paper and to feed action irrelevant with operation of recording, paper.
In addition, above-mentioned embodiment is illustrated as the example of the ink-jet printer of an example of tape deck that the recording paper of an example as medium is recorded applying the present invention to, but be not limited to this, also feeder unit that can be applied to other, that feed medium.Can be applied to such feeder unit for example take the image read-out that scanner is representative, original copy is sent to the feeder unit that reads position (device that is called as automatic sheet feeder (ADF)).
