By adopting a configuration in which the projecting piece 22B1 and the lock member main body 22A are integrated from the back surface 16R side, the operation location can be exposed to the outside of the insert 10. Moreover, since the vertical direction (arrow A direction in FIG. 4) length of hook part 22B2 and protrusion piece 22B1 is formed shorter than the vertical direction (arrow A direction in FIG. 4) length of through-hole 20, The lock member 22 can be moved in the vertical direction (vertical direction) on the groove 16S.

  Further, as shown in FIGS. 5 and 6, a rotating shaft 24 extending along the horizontal direction (the direction of arrow C in FIG. 1) is attached to the distal end portion of the column member 16. A lid member 26 is attached to the rotary shaft 24 so as to be rotatable about the axis of the rotary shaft 24. The lid member 26 includes a lid member body 26A that has a rectangular shape in plan view (see FIG. 3). An attachment portion 26B that is attached to the rotary shaft 24 is formed on the lower surface of the lid member main body 26A. When the mounting portion 26 </ b> B rotates about the rotation shaft 24, the lid member 26 can rotate about the rotation shaft 24. Further, a contact piece 26C that contacts the push-up portion 22C when the lock member 22 moves upward is formed at a position on the lower surface of the lid member main body 26A and in the vicinity of the attachment portion 26B. Further, a cover portion 26D that covers the distal end portion of the insertion member 14 is formed on the lower surface of the lid member main body 26A and in the vicinity of the distal end portion. In a state where the lid member main body 26A and the distal end portion of the insertion member 14 are in contact with each other, the cover portion 26D covers the distal end portion of the insertion member 14 and the vicinity thereof. Further, in the state where the lid member 26 is pushed up to the maximum (the state shown by the solid line in FIG. 5), the position of the center of gravity of the lid member 26 is located closer to the insertion member 14 (front side) than the column member 16. Is set to

Next, the action of the shape insertion according to the present embodiment will be described.
The state where the lid member 26 of the insert 10 covers the tip of the insert member 14 will be described below as an initial position.

  First, as shown in FIGS. 1 and 4, when the lid member 26 is substantially parallel to the base member 12, the distal end portion of the insertion member 14 and its vicinity enter the inside of the cover portion 26 </ b> D of the lid member 26. The tip portion is in contact with the lid member main body 26A. As described above, when the shape insert 10 is not used, the lid member 26 and the tip end portion of the shape insert member 14 are always in contact with each other, so that the tip end portion of the shape insert member 14 can be easily protected.

  On the other hand, as shown in FIG. 5, when the recording medium is inserted into the insertion member 14, the lid member 26 is rotated around the rotation shaft 24 to open the distal end portion of the insertion member 14. In a state where the lid member 26 is pushed upward as much as possible (a state indicated by a solid line in FIG. 5), the lock member 22 is slid upward. At this time, since the plurality of protruding portions 22D are formed on the lock member 22, even when the lock member main body 22A is operated with a finger, the finger does not slide relative to the lock member main body 22A. Thereby, the operativity of the lock member 22 can be improved.

  When the lock member 22 is slid upward, the push-up portion 22C formed on the lock member 22 comes into contact with the contact piece 26C formed on the lid member 26. At this time, as shown in FIG. 6, the convex portion 22 </ b> E formed on the lock member 22 engages with the concave portion 16 </ b> T formed on the column member 16 in a state where the push-up portion 22 </ b> C is in contact with the contact piece 26 </ b> C. Thereby, the locking member 22 stops at the uppermost position without unexpectedly sliding down. As a result, the state where the lid member 26 is lifted upward can be maintained, and the non-contact state between the lid member 26 and the distal end portion of the insertion member 14 can be easily maintained with a simple configuration. Further, in this non-contact state, a recording medium such as paper can be continuously inserted and removed from the tip of the insertion member 14. As described above, according to the shape insert 10 of the present embodiment, the operation of inserting the recording medium into the shape insert member 14 can be performed simply and easily.

  In the above operation, the cover member 26 is first pushed upward with a finger and then the lock member 22 is slid upward. However, the order is not limited to this. For example, the contact piece 26C is pushed up by the push-up portion 22C by sliding the lock member 22 upward as it is in a state where the lid member 26 and the tip of the insertion member 14 are in contact with each other. Thereby, the lid member 26 rotates around the axis of the rotation shaft 24, and the lid member 26 is pushed upward. Thus, the non-contact state between the lid member 26 and the tip of the insertion member 14 can be realized only by sliding the lock member 22 upward without pushing the lid member 26 upward with a finger.

  Next, when the insertion of the recording medium into the insertion member 14 is completed and the lid member 26 and the tip of the insertion member 14 are brought into contact with each other, the lock member 22 is slid downward. That is, the lock member main body 22A is pushed downward with a finger. At this time, since the plurality of protruding portions 22D are formed on the lock member 22, even when the lock member main body 22A is operated with a finger, the finger does not slide relative to the lock member main body 22A. When the lock member 22 is slid downward, the engagement between the convex portion 22E formed on the lock member 22 and the concave portion 16T formed on the column member 16 is released, and the lock member 22 slides downward. . When the lock member 22 slides downward, the push-up portion 22C also moves downward, so that pressure from below does not act on the contact piece 26C. Here, since the center of gravity of the lid member 26 is located closer to the insertion member 14 than the column member 16 at the uppermost position, the lid member 26 is directed downward around the axis of the rotary shaft 24 by its own weight. Rotate. When the lid member 26 is rotated downward about the axis of the rotary shaft 24, the distal end portion of the insertion member 14 and its vicinity enter into the cover portion 26D formed on the lid member 26, and the lid 26 A of member main bodies and the front-end | tip part of the shape insertion member 14 contact. Thereby, as shown in FIG. 1 thru | or FIG. 4, the contact state of the skull member 26 and the front-end | tip part of the shape insertion member 14 is realizable. Thus, in the shape insert 10 of this embodiment, the lid member 26 and the shape insert member 14 can be automatically brought into contact with each other only by sliding the lock member 22 downward.

  In the above operation, the order in which the lock member 22 is slid downward with the finger and the lid member 26 is automatically rotated downward has been described. However, the present invention is not limited to this order. For example, the convex portion 22E formed on the lock member 22 engages with the concave portion 16T formed on the support member 16, and the lid member 26 is rotated downward as it is with the lid member 26 in the uppermost position. The distal end portion of the insertion member 14 may be covered with the lid member 26 by rotating around the axis of the shaft 24. At this time, the engagement between the convex portion 22E formed on the lock member 22 and the concave portion 16T formed on the support member 16 is released, and the lock member 22 slides downward.

  Moreover, although the said embodiment demonstrated the structure which formed the convex part (stopper part, engaging part) 22E in the lock member 22, and formed the recessed part (stopper part, engaged part) 16T in the support | pillar member 16. However, the present invention is not limited to this. For example, a concave portion (stopper portion, engaging portion) is formed in the lock member 22, and a convex portion (stopper portion, engaged portion) is formed in the column member 16, You may make it engage. In particular, the stopper portion can be configured simply by configuring the stopper portion with a convex portion and a concave portion.

  Moreover, in the said embodiment, since the contact piece 26C which contacts the pushing-up part 22C of the lock member 22 was formed in a part of the cover member 26, in order to make the cover member 26 and the lock member 22 contact, the cover member 26 whole There is no need to increase the size. As a result, the insert 10 can be reduced in size.

Further, an operation piece (not shown, operation portion) is attached to or integrally formed with the lock member main body 22A or the claw portion 22B of the lock member 22, and the operation piece passes through the through hole 20 and protrudes to the back surface side of the column member 16. You may comprise. Thereby, the lock member 22 can be easily slid up and down by operating the operation piece up and down with a finger. As a result, even when a plurality of recording media are inserted into the insertion member 14 and stacked, the lock member 22 can be easily operated by the operation piece.
The operation piece is not limited to the configuration in which the operation piece protrudes to the back surface side of the support member 16 through the through-hole 20, and is stacked on the surface of the support member 16 and the recording medium is inserted into the insertion member 14. If the recording medium is provided in a portion other than the portion facing the laminated region, the lock member 22 can be easily operated by the operation piece even in a state where the recording medium is inserted into the insertion member 14 and laminated.
