7. a kind of piano turns over spectral apparatus, it is characterised in that: its working principle are as follows: by No.1 motor (6-1) and suction pump (6-3)
It is connected with the power supply in electric cabinet (4), player passes through floor push (5) control No.1 motor (6-1) and suction pump (6-3)；
When needing page turning, No.1 motor (6-1) to be opened, No.1 motor (6-1) driving No.1 shaft (6-2) starts turning, thus
So that No. two bevel gear (6-5) driving No.1 bevel gear (6-4) rotations, No.1 bevel gear (6-4) drive suction tube (6-7) in pleasure
It is rotated in spectrum (3), suction tube (6-7) opens suction pump (6-3) at the right side of music score (3), by sucker (6-8) by page
Face attracts on the lateral wall of suction tube (6-7), then controls No.1 motor (6-1) and rotates backward, so that suction tube (6-7) is suitable
Hour hands rotation, the page are opened on left side from right side, at this point, No. two motors (8-1) are opened, No. two motors (8-1) are by drawstring
(8-8) is wound around on spool (8-3), so that music score (3) are opened in lift-off on elastic steel sheet (8-6), the page opened is allowed to fit to a left side
On the page of side；It closes suction pump (6-3), the page is fallen under the effect of gravity, is then driven No. two motor (8-1) reversions, is made
Elastic steel sheet (8-6) is obtained to be pressed on the surface of music score (3).
