Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet clamping device.

[0002]

2. Description of the Related Art A structure in which an elastic body is interposed between a main body plate and a holding piece, and a paper sheet is held between the main body plate and the holding piece by urging of the elastic body without giving specific examples. There are things.

[0003]

In the prior art, the holding state of the paper sheet is maintained by the urging of the elastic body, but when the paper sheet is held, the holding operation is performed against the elastic body. The holding gap between the main body plate and the holding piece must be maintained with the fingertip.

The present invention has been devised with the object of providing a paper sheet holding device having a novel structure which does not require the fingertip to maintain the open state between the main plate and the holding piece.

[0005]

Means for Solving the Problems On one surface of the main plate, a pair of outer support pieces are interposed between the outer support pieces, and a pair of inner support pieces arranged in front of the outer support pieces are respectively provided. A holding piece for holding the paper sheet with the main body plate at the tip thereof is rotatably mounted on the outer supporting portion piece by a first rotation shaft, and a paper sheet is provided between the holding piece and the main body plate. A spring is provided for urging the holding piece in the holding direction, and an operating piece whose rear end comes into contact with and separates from the main plate is protrudingly engaged with a window provided at an intermediate portion of the holding piece. A pressing pin is provided laterally on one of the side pieces so as to slide against the lower surface of the holding piece against the bias of the spring body and keep the holding piece standing upright.

1 is a plan view, FIG. 2 is a cross-sectional view taken along the line aa of FIG. 1, and FIG. 3 is a cross-sectional view taken along the line bb of the paper sheet according to the present invention. FIG. 4 is a sectional view taken along the line cc of FIG. 4, and FIG. 5 is a front view showing an open state.

In the drawing, reference numeral 1 denotes a main plate, and a pair of outer support portions 2 and 2 and the outer support portions 2 are provided on the rear end of one surface of the main plate 1.
A pair of inner support pieces 3, 3 interposed between the two, and arranged in front of the outer support piece 2, are provided upright.

Reference numeral 4 denotes an operation piece, which is provided on the outer surfaces of a pair of side pieces 4a, 4a provided on the operation piece 4 on the second rotation shafts 5, 5 and on the front side of the second rotation shafts 5, 5. The operating pins 4 are engaged with the engaging holes 7 provided on the inner surface of the inner supporting portion 3 to engage the second rotating shaft 5 with the inner supporting portion 3. The pressing pin 6 is rotatably assembled, and is disposed at a position where the pressing pin 6 is displaced to a position rearward of the second rotation shaft 5 with rotation of the operation piece 4, that is, the side piece 4 a.

When the operating piece 4 is rotated in the direction of the rear end of the main plate 1 (counterclockwise in FIG. 2), the rear end 4 'is located on the one surface of the main plate 1 as shown in FIG. They are arranged so that they are in contact with each other and their rotation is regulated.

FIG. 8 shows a holding piece. The holding piece 8 has a pair of side pieces 9 and 9 provided on the rear side and a window 10 at the center in the left-right direction.
The operation piece 4 rotatably supported by the inner support portion 3 is movably engaged with the operation piece 4 such that the tip 4 ″ projects from the window 10. The lower surface 18 of the holding piece 8 is disposed on the rotation locus of the pressing pin 6 provided on the operation piece 4.

A first rotating shaft 11 protrudes from the inner surface of the side piece 9 of the holding piece 8, and the first rotating shaft 11 is provided on the upper end of the outer supporting piece 2 in an arc shape. The upper end of the rising portion 13 provided on the auxiliary frame 19 fitted and locked to the rear end of the main plate 1 while being engaged with the lower side of the guide portion 12 of FIG. The main plate 1 is rotatably assembled so as to be arranged.

In the figure, reference numeral 23 denotes a winding part 2 on both sides of the operation piece 4.
The spring body 23 is provided with elasticity provided with 3a, 23a. The spring body 23 engages the notch 14 provided in the holding piece 8 with the intermediate portion 23 ', and the engaging holes 15 provided in the main plate 1 at both left and right ends. The holding piece 8 is always urged in the holding direction of the paper sheet by the urging of the spring body 23 to hold the paper sheet with the main plate 1.

In the drawing, reference numeral 16 denotes a writing instrument holder fitted and locked to the holding piece 8, and 17 denotes a recess provided on the front edge of the window 10 of the holding piece 8, and the operation piece is provided by the presence of the recess 17. The tip 4 ″ of the 4 is easily picked.

The lower surface 18 of the holding piece 8 is arranged to have a length (width) in a range positioned on the trace of the rotation axis of the pressing pin 6 about the second rotation shaft 5.

FIG. 2 shows, for example, a state in which the holding piece 8 holds the paper sheet with the main body plate 1 by the rotational bias of the spring body 23.

In this state, when the fingertip is inserted into the recess 17 and the tip 4 ″ of the operation piece 4 is picked up and rotated counterclockwise in the figure, the operation piece 4 is rotated about the second rotation shaft 5. With the rotation, the pressing pin 6 is moved to the lower surface 18 of the holding piece 8.
, And pushes up the holding piece 8 against the bias of the spring body 23, and the holding piece 8 rotates about the first rotation shaft 11 to release the holding state of the paper sheet.

When the rotating operation of the operating piece 4 is further continued, the pressing pin 6 moves beyond the vertical position passing through the center of the pressing pin 6 and the center of the second rotating shaft 5 with respect to the lower surface of the holding piece 8. Move along the lower surface 18 of the holding piece, the rear end 4 'of the operating piece 4 comes into contact with the main body plate 1 and the rotation thereof is restricted, and as shown in FIG. The released state of the sheet is maintained.

[0018]

[Effect of the Invention] Since the present invention has the configuration as described above,
By rotating the operation piece, the holding piece rotates and stands up, and the upright state is maintained, and it is not necessary to keep the open state between the main body plate and the holding piece with a fingertip. Can be provided.
