In addition, be formed as hook-shaped by the shape of the front end by rodmeter 111, near jut 601, between rodmeter 111 and the bottom surface of transport path 301, be formed with gap 604 than jut 601 backrest surface side.This gap 604 is formed as reducing along with close to jut 601, increases along with being separated from jut 601.Thereby, it is possible to the front end of the recording medium carried from rear side towards front face side in transport path 301 is guided to detection position effectively.
The rodmeter 111a of one side is arranged to the position that jut 601 is positioned at jut 601 side on the front than the rodmeter 111b of the opposing party.That is, the detection position of the rodmeter 111a of a side leans on the upstream side of the throughput direction of recording medium to arrange than the detection position of the rodmeter 111b of the opposing party.
In each rodmeter 111, be greater than part than jut 601 side on the front relative to throughput direction (horizontal direction) angulation (hereinafter referred to as " angle Y ") than the part of jut 601 backrest surface side relative to throughput direction (horizontal direction) angulation (hereinafter referred to as " angle X ").By making angle X be greater than angle Y, the front end that can make the recording medium inserted from the rear side of printer 100 thus reliably with rodmeter 111 to touching.
The axle core of rodmeter 111 around axle 501 together with axle 501 rotates along the clockwise direction in Fig. 6, therefore, by the front end that makes the recording medium inserted from the rear side of printer 100 reliably with rodmeter 111 to touching, thus axle 501 can be made reliably to rotate.Thereby, it is possible to reliably detect the recording medium inserted from the rear side of printer 100.
By making angle X be greater than angle Y, that is, by making angle Y be less than angle X, the front end of the recording medium that the front face side from printer 100 can be inserted guides to detection position swimmingly.Thereby, it is possible to make axle 501 reliably rotate.Thus, even if when recording medium inserts from the front face side of printer 100, also can reliably detect this recording medium.
As described above, projection arranges two to 402 in the mode corresponding respectively to each rodmeter 111 (the rodmeter 111a of a side and the rodmeter 111b of the opposing party).Therefore, projection is in 402, and the projection of a side opposed with the rodmeter 111a of the side projection to the position ratio of 402a the opposing party opposed with the rodmeter 111b of the opposing party is arranged the upstream side of the position of 402b by the throughput direction of recording medium.
Fig. 7, Fig. 8 and Fig. 9 are the key diagrams of the detection action representing recording medium.In Fig. 7, Fig. 8 and Fig. 9, illustrate respectively rodmeter 111 and the projection corresponding with this rodmeter 111 to 402 the state observed from side (right side from the state faced by front face side and printer 100).
As shown in Fig. 7, Fig. 8 and Fig. 9, when observing rodmeter 111 from side, the state that each rodmeter 111 staggers in front and back along throughput direction with the jut 601 of the rodmeter 111b of the jut 601 of the rodmeter 111a of a side and the opposing party is arranged.Specifically, each rodmeter 111 is arranged in jut 601 mode that side is located on the front of the jut 601 of the rodmeter 111a of a side than the rodmeter 111b of the opposing party.
Thus, time in transport path 301 from front face side towards rear side conveying recording medium, the jut 601 of the rodmeter 111a of a side is positioned at the upstream side of the throughput direction of this recording medium.And, by the jut 601 of the jut 601 of rodmeter 111a than the rodmeter 111b of the opposing party is located side on the front, thus in transport path 301 from rear side towards front face side conveying recording medium time, the jut 601 of the rodmeter 111b of the opposing party is positioned at the upstream side of the throughput direction of this recording medium.
Like this, in printer 100, no matter being from front face side towards rear side conveying recording medium, or from rear side towards front face side conveying recording medium, be all positioned at the upstream side of the throughput direction of recording medium at the jut 601 being positioned at left side under the state faced by throughput direction and printer 100.
As shown in Figure 7, when recording medium is not in detection position, jut 601 abuts with the bottom surface 602 of transport path 301.In this case, jut 601 be in projection on the width of transport path 301 between 402 by the state of this projection to 402 clampings.The recording medium carried from upstream side to downstream (from side direction rear side above) in transport path 301, before the jut 601 of rodmeter 111b arriving the opposing party and the abutted position of the bottom surface 602 of transport path 301, first arrives the jut 601 of the rodmeter 111a of a side and the abutted position of the bottom surface 602 of transport path 301.
