In addition, under the adsorbed state shown in Figure 11, in locking part 75 and the structure for constituting the main cover 43 of movable body 6 Between retainer 51 at the secondary portion of matrix 5, be formed with the stroke s1 of the sucker valve 9 and stroke s2 of the clearance amount it The comparable clearance of size of sum.Under the intermediate state shown in Figure 12, between the locking part 75 and the retainer 51, It is formed with the clearance with the comparable sizes of stroke s1 of the sucker valve 9.It is adsorbed under releasing state shown in Figure 13, the card Determine part 75 with the retainer 51 to connect, the clearance between the locking part 75 and the retainer 51 is 0.

Here, in the above-described embodiment, in order to be released with shirtsleeve operation and by few job step Adsorbed state, more specifically in order to by for make with cutter T it is mobile by the operation lifted upward makes the access 3 It opens so as to desorb state, opening/closing unit 4 is made to have 10 and of the lower silicon rubber piece functioned as valve seat It can be from being tightly attached to the lower silicon rubber piece 10 and the closed position (C) that blocks the access 3 is to from the lower silicon rubber piece 10 Leave and so that the access 3 is opened open position (O) until between the sucker valve 9 retreated, and be configured to, it is described can In the case that kinetoplast 6 is operated upward, in response to this, the sucker valve 9 is from closed position (C) to open position (O) It is mobile.But the composition of opening/closing unit is not limited to the such composition of above-mentioned embodiment, can also use will be used for into enforcement The operation portion for the operation that the sucker valve of composition opening/closing unit is separate relative to valve seat is set in such as band cutter main body Sucker near position etc., other forms.

In addition, as described above, in the above-described embodiment, in order to enable even if being pulled out with band under adsorbed state Operation etc. and the band cutter main body 1 is applied be difficult to expect vibration etc. in the case of the adsorbed state will not be solved It removes, the initial stage fine motion for absorbing the movable body 6 is provided between the movable body 6 and the sucker valve 9 to prevent the initial stage The clearance part that fine motion is transmitted to the sucker valve 9.It may, however, also be passing through other units so that even if to institute State band cutter main body 1 be applied be difficult to expect vibration etc. in the case of the adsorbed state will not be released from.

Also, in order to prevent or inhibit the center of gravity with cutter T in the cut-out with t single as band cut-out to being configured with The generation thus with the cutter T unfavorable conditions toppled over is moved in the side of the cutter 11 of member, in the above-described embodiment, described The axle center 2c of the ora terminalis of the side for being configured with cutter 11 in bottom surface with cutter main body 1 i.e. front-end edge 1a and the sucker 2 The distance between d, be set to bigger than the radius r of the sucker 2.However, can certainly make the bottom surface with cutter main body In the ora terminalis for being configured with the side with cutting unit and sucker the distance between axle center for sucker radius hereinafter, separately setting It sets for anti-down unit.

Moreover, in the above-described embodiment, by the lower silicon rubber piece 10 functioned as valve seat and as spool and The upper silicon rubber piece 101 functioned using elastomer made of same material (silicon rubber) being constituted, but spool and valve seat are certain It can also be by utilizing the material such as elastomer resin (English other than silicon rubber：Elastomer resin) formed elastomer It constitutes, naturally it is also possible to be made of spool and valve seat different materials.But if by spool and valve seat by utilizing same material Elastomer made of material is constituted, then is easy to be close to spool in closed position (C) valve seat, is in other words difficult between spool and valve seat To generate gap, therefore it can more effectively inhibit air from sucker 2 and be revealed by the space S P between adsorption plane S.

In addition, foregoing describe embodiment in, for sucker to be fixed on to the bottom surface of the principal part as matrix The case where be illustrated, but sucker can also be enable relative to matrix horizontal rotation.In other words, can also be configured to make band Cutter main body can be turned round relative to the sucker around the axle center of the sucker.

In addition, the shape with cutter main body can also arbitrarily be set.In which case it is preferable that in order to pass through Sucker steadily adsorbs band cutter main body, is arranged for making the center of gravity position with cutter main body with cutter main body described In the counterweight of the center of gravity setting on the axle center of the sucker.

Also, above explanation is related to as the band cutter main body for being used as stationery main body can be made to be adsorbed in by sucker By the band cutter of the stationery of adsorption plane, but the present invention can also be suitable for the stationery other than cutter certainly.As in this way Stationery example, can enumerate can be such that the penholder main body for being used as stationery main body is adsorbed in by the penholder of adsorption plane by sucker Deng.

Furthermore, it is possible to make various changes without departing from the spirit of the present invention.
