結を外すことが必要になるなどの問題がある。(Problems to be solved by the invention) The conventional protective cover opening / closing device shortens the air cylinder and lowers the protective cover when the printing unit is closed.
If a finger or the like is sandwiched between the frame and the protective cover, the operating force of the air cylinder may be directly applied to the finger or the like, resulting in injury, and the protective cover may be raised further than the position shown by the chain line in Fig. 7. In order to increase the opening range by increasing the stroke of the air cylinder, the size of the device becomes large, and it becomes necessary to remove the pin connection of the protective cover of the air cylinder.

にしている。(Means for Solving the Problems) According to the present invention, an opening / closing arm whose base end is pivotally attached to a frame of a printing unit to rotate and a tip end of the opening / closing arm are pivotally attached to each other. A flip-up protection cover that opens and closes the printing unit, and a biasing force that is connected between the tip of the first link pivotally attached to the frame and swingable and the tip of the actuating protrusion of the opening and closing arm. A damper and a tip end portion of a second link that is pivotally attached to the frame and is capable of swinging, and engages with an operating piece provided at the tip end portion of the first link to return to the frame together with the first link. And a fluid pressure cylinder connected in parallel with the opening biasing damper between the tip ends of the actuating projections. The opening and closing arm for opening and closing the opening and closing damper is provided. The first link and each of the base end parts of the fluid pressure cylinder By swinging the second link and the second link, it is possible to temporarily stop the protective cover when it is closed, and to excessively open the protective cover.

て、開閉用アーム（13）を回動する。The opening / closing arm (13) is pivotally attached (13a) to the frame (12) by pin connection so as to be rotatable about the pivotal attachment (13a), and is connected to the frame (12) by pin connection. The first link (21) pivotally attached (21a) is pivotally attached (18a) (18b) by pin connection between the tip end of the protrusion (13c) protruding from the opening / closing arm (13). The opening urging damper (18) connected to each other always outputs in the extension direction to urge the opening / closing arm (13) clockwise in the drawing, that is, urges in the opening direction.
On the other hand, the second link (22) pivotally attached (21a) to the frame (12) by pin connection is pivotally attached (19a) (19b) by pin connection between the tip end of the protrusion (13). The fluid pressure cylinder (19) connected by the above is controlled to expand and contract by an operation control mechanism (not shown) including a drive source, a pipe, a control valve, etc., and rotates the opening / closing arm (13).

能である。When the fluid pressure cylinder (19) is extended as shown in FIG. 2, the opening / closing arm (13) is rotated rightward in the figure around the pivotal attachment (13a) portion of the base end, and the protective cover (11) is raised. When the protective cover (11) is further raised, the first link (21) and the second link (21) are released as shown in FIG.
The link (22) is rotated rightward in the figure around the pivot (21a) part, and the opening / closing cover (13) is further rotated rightward in the figure more than the stroke of the fluid pressure cylinder (19) to rotate the protective cover (1
It is possible to raise 1) further, ie to an excessively open position.

出すことができる。When the fluid pressure cylinder (19) is shortened, the opening / closing arm (13) is rotated counterclockwise and the protective cover (11) is lowered to the closed position of the printing unit (b) (see FIG. 3).
When a finger or the like is caught between the frame (12) and the protective cover (11) during the closing operation, the first link (21) and the second link (22) are caused by the downward resistance of the protective cover (11). Second
By rotating in the direction (Y) shown in the figure, that is, rotating right in the figure, the lowering of the protective cover (11) is easily stopped, and the finger or the like can be easily extracted.

させて作動を円滑にしている。Since the opening biasing damper (18) always outputs in the extension direction to cancel the weight of the opening / closing arm (13), the protective cover (11), etc., the fluid pressure cylinder (19) expands and contracts to open and close the arm. Rotation of (13), raising and lowering of protective cover (11),
That is, when the protective cover (11) is smoothly opened and closed, and when the resistance of the protective cover (11) is lowered due to a pinch of a finger or the like, the first link (21), due to the relatively small downward resistance, The second link (22) is easily rotated to effectively prevent injuries such as fingers. An operating piece (21b) is provided at the tip of the first link (21), and the operating piece (21b) is
The second link (22) is returned onto the frame (12), and the rotation of the first link (21) and the second link (22) are interlocked with each other to facilitate the operation.

バーの開閉性能を著しく向上する等の効果を有する。(Effect of the Invention) As described above, the present invention is opened between the tip of the first link pivotally attached to the frame of the printing unit and the tip of the actuating protrusion of the opening / closing arm pivotally attached to the frame. The tip of the second link and the tip of the actuating projection of the opening / closing arm that connects the biasing damper and engages with the actuating piece provided at the tip of the first link to return to the frame together with the first link. It has a structure in which a fluid pressure cylinder is connected between the parts, so that the opening biasing damper cancels the weight of the opening / closing arm and the flip-up protection cover, and the fluid pressure cylinder has a protection cover via the opening / closing arm. The second link, which can be opened and closed easily and smoothly, and which can be returned together with the first link, can easily stop the closing operation of the protective cover, effectively prevent the injury of fingers and the like, and also open the protective cover excessively. Easy to protect cover It has the effect of significantly improving the opening and closing performance of the door.
