Embodiment
With reference to Fig. 2 a and Fig. 2 b, Fig. 2 a is the three-dimensional exploded view of the bogey of the utility model first embodiment contact image sensor scan module, and Fig. 2 b is the diagrammatic cross-section of the bogey of the utility model first embodiment contact image sensor scan module.The load bearing seat 1400 of one flute profile is in the bottom of its open slot, dispose comprehensively one with big magnetite 1510 such as bottom surface, the bottom of contact image sensor scan module 1100 also disposes a magnetite 1500, and with respect to the magnetite 1510 of the open slot of load bearing seat 1400 bottom, and be positioned at position above the open slot of load bearing seat 1400.Aforementioned two magnetites relatively to polarity identical, therefore produce the super of a mutual exclusion and contact image sensor scan module 1100 upwards pushed away, with the weight of carrying contact image sensor scan module 1100 apart from power.The open slot size of load bearing seat 1400 is slightly larger than the size of contact image sensor scan module 1100, only moves up and down in open slot so that the open slot of load bearing seat 1400 can limit contact image sensor scan module 1100.The inboard, scanning plane 1110 edge of contact image sensor scan module 1100 tops disposes a plurality of buffer substrate tablets 1300, and contact image sensor scan module 1100 is upwards contacted smooth in document platform 1200 again by these buffer substrate tablets 1300.
Wherein, aforementioned magnetite produces superly acts on the bottom surface of contact image sensor scan module 1100 apart from power comprehensively and fifty-fifty, makes contact image sensor scan module 1100 can be close to the document platform face at any time comprehensively.
With reference to Fig. 3, be the diagrammatic cross-section of the bogey of the utility model second embodiment contact image sensor scan module.Contact image sensor scan module 1100 is positioned at the open slot of the load bearing seat 1400 of a flute profile, and utilize a seal ring 1700, connect airtight the gap between four vertical sidewalls of 1,100 four vertical sidewalls of contact image sensor scan module and open slot, make and form a confined space between contact image sensor scan module 1100 bottom surfaces and the open slot bottom surface, this confined space is full of a fluid 1600, and contact image sensor scan module 1100 is carried by the pressure of this fluid 1600.Wherein, load bearing seat 1400 is connected to a pump 1800 by a pipeline 1810 with aforesaid confined space, and controls the pressure of confined space inner fluids 1600 with this pump 1800.The inboard, scanning plane 1110 edge of contact image sensor scan module 1100 tops disposes a plurality of buffer substrate tablets 1300, and contact image sensor scan module 1100 is upwards contacted smooth in document platform 1200 again by these buffer substrate tablets 1300.
Wherein, the pressure of aforesaid fluid 1600 is the bottom surfaces that comprehensively and fifty-fifty act on contact image sensor scan module 1100, makes contact image sensor scan module 1100 can be close to the document platform face at any time comprehensively.Fluid wherein can be hydraulic fluid or gases at high pressure.
According to above-mentioned embodiment of the present utility model as can be known, the utility model has following advantage at least:
(1) uses a pair of magnetite and produce repel each other comprehensive and average super, make the contact image sensor scan module be close to the document platform face at any time comprehensively, improve known uneven local support strength, to reach best scanning effect apart from power.
(2) the comprehensive and average pressure that utilizes hydraulic fluid or gases at high pressure to produce makes the contact image sensor scan module be close to the document platform face at any time comprehensively, improves known uneven local support strength, to reach best scanning effect.
Though the utility model with the embodiment explanation as above; right its is not that any person skilled in the art is not in breaking away from spirit and scope of the present utility model in order to qualification the utility model; when doing a little change and retouching, therefore protection domain of the present utility model is to be as the criterion.
