Description

[Detailed description of the invention] The present invention provides an operation cover that can be opened/closed, attached/detached, and locked, which is used when setting or replacing an ink phone, printing paper, etc. in a printer device used in a terminal device, for example. Regarding improvements to the mechanism.

In printer devices conventionally used for terminal devices,
As shown in FIG. 1A, the main body 1 is composed of a paper holder 2, a platen 3, a front cover 4, etc., and an operation cover 6 is attached to the front cover 4 using a butterfly plate 5 or the like.

In such a printer device, when setting or replacing an ink phone or printing paper (not shown), the operation cover 6 is opened in the direction of the arrow to the dotted line position as shown in FIG.

However, when setting or replacing ink ribbons, printing paper, etc., each time the operation cover 6 is opened as shown in Figure 1, one end of the butterfly plate 5 hits the front cover 4, making it difficult to operate. If the cover 6 is opened forcefully, the front cover 4 will be damaged, and such a butterfly plate 5 requires a special shape due to the structure of the printer device, and general commercially available products cannot be used. There are problems such as it takes a lot of man-hours, hinders the workability, and increases costs.

The object of the present invention is to solve the above-mentioned problems, and the object is to provide an opening/closing mechanism for an operation cover in which the operation cover is attached to the main body so that it can be opened and closed, and the operation cover is in contact with the main body. a stopper metal fitting that is supported and protrudes toward the main body at an end of the operating cover on the opening/closing fulcrum side with respect to the main body; and an L provided on a surface of the operating cover on the main body side so as to protrude near the opening/closing fulcrum. The main body includes a stopper that engages with the stopper fitting to hold the operation cover in the open state when the operation cover is opened, and a stopper that engages with the stopper metal fitting when the operation cover is opened, and a This is achieved by an operating cover opening/closing mechanism characterized by comprising a locking leaf spring that holds the operating cover in an open state by engaging with an L-shaped hook fitting.

The actual state-of-the-art illustration of the operating cover opening/closing mechanism according to the present invention is shown in Fig. 2, a perspective view of the main parts, Fig. 3, a cross-sectional side view of the main parts of the operating cover and main body, and a cross-sectional view of the main parts with the operating cover closed. When viewed from the side, open its operation cover (.

This will be explained using a cross-sectional side view C of a main part.

As shown in the figure, the operating cover opening/closing structure of the present invention has a second
As shown in the figure, a transparent operation cover 6 made of acrylic etc.
On the left and right sides of the main body 1, there is formed a hooking metal fitting 7 and a stopper metal fitting 8, and on both left and right sides of the front cover of the main body 1, there are plate springs A' for locking.

A locking leaf spring 9 and a stopper 10, which are integrally provided with B', are provided.

In the operation cover opening/closing mechanism configured in this way,
As shown in Fig. 3a, the tip of the operation cover 6 is inserted in the direction of the arrow with one end of the front cover 4 as a fulcrum and hooked onto the locking leaf springs 9 provided on both left and right sides of the front cover 4 of the main body 1. A', B' of the locking plate spring 9 is inserted by inserting the metal fitting 7 into the spring 9 via A', B' of the locking plate spring 9, and then closing the fitting 7 as shown in FIG. 3. ', the operation cover 6 is locked by the hooking metal fitting 7.

That is, when the operating cover is in the closed state with respect to the main body, the operating cover is held in the closed state by the hooking metal fitting of the operating cover engaging with the locking leaf spring 9 provided on the main body.

Next, as shown in FIG. 3C, when the tip of the operation cover 6 is lifted upward using one end of the front cover 4 as a fulcrum, the hooking metal fitting 7 is attached to the spring 9 via the locking leaf spring 9 AZ Bj.
When the operation cover 6 is further rotated, the stopper fitting 8 hits the stopper 10 and the operation cover 6 is held in an open state.

Furthermore, since the operation cover 6 is simply provided in contact with the front cover 4 of the main body 1, when removing the operation cover 6 for maintenance or inspection, the stopper fitting 8 must be attached to the stopper 1.
The operation cover 6 can be easily removed by separating it from 0 and lifting the operation cover 6 upward.

Therefore, when setting or replacing an ink ribbon or printing paper, etc., in such an operation cover opening/closing mechanism, the operation cover 6 is opened toward you via the locking leaf spring 9, and the stopper fitting 8 is used to open the operation cover 6 toward the front. held at 10 and opened l,
Then you can do this.

As explained above with reference to the embodiments, according to the operating cover opening/closing mechanism according to the present invention, the operating cover can be opened/closed, attached/detached, and locked with a simple structure that is engaged with a locking plate spring and a hook fitting. This is advantageous for maintenance and inspection, and the parts can be easily machined, resulting in cost reduction.

Furthermore, the opening/closing/attachment/detaching and locking mechanisms for the operation cover are all provided on the opening/closing fulcrum side of the operation cover's main body and inside the main body, so when the operation cover is opened, clothes cannot be caught on the engaging protrusion. There is no damage to the appearance (no hinges or the like protrude from the surface of the main body, and if the operation cover is a transparent cover, only the opening/closing fulcrum side is made opaque).
