JPS5912791Y2 - Sheet-removal device for sheet-type recording and playback machines - Google Patents

Description

[Detailed description of the invention] In this invention, when the sheet presser of the sheet-type recording/reproducing machine is released, the sheet push-up plate provided on the underside of the sheet moves in conjunction with the release, thereby lifting the sheet away from the guide pin. This relates to a sheet removal device for a sheet-type recording and reproducing machine that can be removed and shifted laterally, and its purpose is to extremely easily replace the sheet.

Conventional sheet-type recording/playback machines do not have a device to automatically remove the sheet, as shown in Fig.
Since the sheet was removed, there was a drawback that the hole 3 for position alignment of the sheet was damaged and became unusable to the extent that it could no longer be aligned.

This invention works in conjunction with the release operation of the sheet presser to remove the sheet from the guide pin, move it sideways and keep it lifted, and then the sheet push-up plate automatically returns to its original position, making it extremely easy to replace the sheet. It was designed to eliminate the drawbacks of the conventional method.

Next, one embodiment shown in the attached FIGS. 2 to 6 will be described in detail.

Reference numeral 5 designates a base plate on which a support column 6 is fixed, and a plate 8 having a seat position alignment pin 7 implanted thereon is fixed to the upper end of the base plate 5, and the seat position alignment pin 7 protrudes from the cover 9.

A sheet 2 has a position alignment hole 3 fitted into the sheet position alignment pin 7, and a sheet presser 1 presses the sheet.

The sheet presser foot 1 can freely rotate outward.

In the present invention, the lever 10 is pivotally connected to the holding plate 22 fixed to the support column 6 with a pin 11 in such a conventionally well-known structure, and when the sheet presser 1 rotates outward, the outer end of the lever 10 is rotated. The lever 10 is arranged so that when pressed, the lever 10 can be rotated counterclockwise about the pin 11.

A lever 13 whose upper end surface 12 is inclined diagonally upward to the right is pivotally attached to the right end of the lever 10 by a pin 14.

Reference numeral 15 denotes a sheet push-up plate, and its upper horizontal portion is provided with a hole 16 that fits into the sheet position alignment pin 7. Its lower end is integrated with a plate 17, and the right edge of the plate 17 has a hole 16 that is perpendicular to the plane of the paper. An engaging piece 18 is formed which is bent to
is placed on the right edge step 19 of the lever 13.

20 is a guide pin, and 21 is a return spring for the lever 13.

Next, the effect will be explained.

In the state shown in FIG.
The sheet push-up plate 15 is placed on the substrate 5 while being guided by the sheet 2 .

Next, when the sheet presser 1 is rotated outward by about 90 degrees as shown in FIG. 3, the sheet presser 1 presses the outer end of the lever 10 downward, so the lever 10 rotates counterclockwise and the lever 13 also moves upward. The stepped portion 19 engages with the bent piece 18 and pushes the plate 17 upward along the guide pin 20, so the sheet push-up plate 15 pushes the sheet 2 upward, but the sheet position alignment pin 7 does not I can't get out.

When the sheet presser 1 is further rotated as shown in Fig. 4, the lever 13
Since the upper end surface 12 of the lever 13 is in contact with the plate 8, the lever 13 is
4 in the clockwise direction, and the plate 17 also rotates together, so the sheet push-up plate 15 pushes the sheet 2 to the right and upwards, so that it comes out of the sheet position alignment pin 7. Seat 2 is pushed slightly to the right.

Next, when the sheet presser 1 is further rotated as shown in FIG. 5, the rotation of the plate 17 is stopped by the plate 8, and only the lever 13 is further rotated, so that the stepped portion 19 comes off from the bent piece 18, and the plate 17 and The integrally constructed sheet pushing up plate 15 returns to its original position due to its own weight.

At this time, since the position alignment hole 3 of the sheet 2 is shifted from the sheet position alignment pin 7, the sheet 2 remains placed on the sheet position alignment pin 7.

When the hand is released from the sheet presser 1, the lever 10 and the lever 14 are restored to their original states by the elasticity of the return spring 21, and the sheet presser 1 also settles into a predetermined open position as shown in FIG.

Therefore, the seat 2 can be easily replaced.

The present invention operates the sheet push-up plate in conjunction with the sheet presser release operation, raises the seat, then shifts it to the side, removes it from the alignment pin, and automatically returns the seat push-up plate to its original position. Therefore, the sheet can be replaced extremely easily.

In addition, if you raise the seat push-up plate or move it to the side,
Of course, the means for automatically returning to the original position may be a means other than the above-mentioned embodiments.
