         2 . The printer according to  claim 1 , wherein the feed tray stores a recording medium and is capable of sliding between a first position corresponding to a drawn-out position from the device body and a second position corresponding to an accommodated position within the device body. 
     
     
         3 . The printer according to  claim 2 , wherein the regulation unit is pivotable between the first posture not regulating sliding of the feed tray and the second posture regulating sliding of the feed tray. 
     
     
         4 . The printer according to  claim 3 , wherein the pressing portion presses a portion of the regulation unit in a first direction from the first position toward the second position to pivot the regulation unit from the first posture to the second posture when the feed tray slides from the first position and reaches the second position. 
     
     
         5 . The printer according to  claim 4 , wherein the regulated portion is pressed in the first direction by another portion of the regulation unit moved to the second posture by the pressing portion at a time of arrival of the feed tray at the second position. 
     
     
         6 . The printer according to  claim 1 , wherein the regulation unit pivots between the first posture and the second posture, and maintains each of the first posture and the second posture until a force having a strength equal to or larger than a predetermined strength is applied to the regulation unit. 
     
     
         7 . The printer according to  claim 6 , wherein
 the regulation unit includes:
 a pivoting portion pivotable between the first posture and the second posture around a pivot axis extending parallel or substantially parallel to a second direction crossing the first direction; 
 a first portion connected with the pivoting portion, and extending in a direction crossing the pivot axis; 
 a second portion connected with the pivoting portion, and extending in a direction crossing the pivot axis and different from an extension direction of the first portion; and 
 a maintaining portion that maintains the pivoting portion in each of the first posture and the second posture until a force having a strength equal to or larger than the predetermined strength is applied to the pivoting portion. 
   
     
     
         8 . The printer according to  claim 7 , wherein
 the maintaining portion includes:
 a first spring that includes one of a first projection and a first recess, and urges the one of the first projection and the first recess toward the pivoting portion; and 
 the other of the first projection and the first recess provided at two positions on an outer circumference of the pivoting portion, and fitted to the one of the first projection and the first recess of the first spring at one and the other of the two positions of the pivoting portion in the first posture and the second posture of the pivoting portion, respectively; and 
   the maintaining portion maintains the pivoting portion in each of the first posture and the second posture by fitting between the one of the first projection and the first recess of the first spring and the other of the first projection and the first recess provided at one of the two positions of the pivoting portion until a force having a strength equal to or larger than the predetermined strength is applied to the pivoting portion.   
     
     
         9 . The printer according to  claim 7 , wherein
 the second portion includes a first protrusion protruding in a moving direction of the second portion at a time of pivoting from the first posture to the second posture; and   the regulation unit retains the feed tray at the second position by bringing the first protrusion of the second portion into contact with the regulated portion when the feed tray reaches the second position.   
     
     
         10 . The printer according to  claim 1 , wherein
 the feed tray includes an inclined surface inclined relative to the first direction and a third direction crossing the first direction and the vertical direction; and   the body includes:
 a first contact portion that comes into contact with the inclined surface in the third direction when the feed tray reaches the second position; and 
 a second contact portion that is disposed at a position different from the position of the first contact portion in the first direction, and comes into contact with the feed tray in the third direction. 
   
     
     
         11 . The printer according to  claim 10 , wherein
 the second contact portion includes a second projection, and a second spring that urges the second projection toward one side in the third direction; and   the feed tray includes a second recess fitted to the second projection of the second contact portion when the feed tray is located at the second position.   
     
     
         12 . The printer according to  claim 10 , wherein
 the pressing portion is a second protrusion that projects in the first direction from a portion of the feed tray on a side in the third direction;   the second protrusion includes the inclined surface;   a portion of the body on the side in the third direction further includes a through hole through which the second protrusion penetrates; and   the first contact portion is a portion of an inner circumference of the through hole.   
     
     
         13 . The printer according to  claim 1 , further comprising a re-storage unit that re-stores the paper subjected to printing on one surface of the paper by the printing unit in the feed tray in a storage state such that the surface of the paper on the side opposite to the surface set prior to printing by the printing unit faces upward. 
     
     
         14 . The printer according to  claim 1 , wherein the regulated portion includes a through hole in the feed tray. 
     
     
         15 . The printer according to  claim 14 , wherein the through hole and the pressing portion define a second regulation unit.
