Description

[Detailed description of the invention] This invention relates to a structure for easily attaching and removing a lid to a device body and supporting it. This makes it easy to attach and remove the cover, making maintenance and inspection of the printer section or removing paper jams inside the device convenient.

Conventionally, this type of device has a structure in which the lid member is fixed to the device body with screws, or a structure in which one end of the lid member is pivotably attached to the device body and the lid member is attached to the device body so that it can be opened and closed. Are known.

However, in the former structure, each time the lid member is attached or removed, it is necessary to remove and tighten the screws, which requires additional handling.

On the other hand, with the latter structure, the inside of the device can be inspected easily because it can be opened and closed. Therefore, it takes time and effort to remove or attach the lid member from the device body.

The present invention was made to eliminate the above-mentioned drawbacks, and in particular, the lid member itself can be attached to the device body with just 77 touches, and it can also be removed without the need for special equipment or complicated work. The present invention provides a support structure for a lid member as described above.

The structure and the like will be described below using an example in which a lid member with a cutter is used, in which a paper cutter is integrally formed with the lid member.

In the figure, reference numeral 1 indicates the main body of the apparatus, and roll paper A is fed into part B of the printer (5) and printed (1), after which it is fed out to the outside of the apparatus 1.

Reference numeral 4 denotes a lid member with a cutter, a blade portion 3 is provided approximately at the center thereof, and a window 14 is provided in front of this blade portion 3.

Further, a stepped locking portion 5 is formed on the front edge of the cutter-equipped lid member 4.

An elastic extension 8 is formed by connecting the stepped locking portion 5 and the connecting portion T at substantially the center thereof, and extends in parallel to the stepped locking portion 5 .

Further, two locking pieces 9 are integrally formed on the rear edge of the cutter-equipped lid member 4, that is, on the opposite side of the side where the elastic extension portion 3 is provided.

Reference numeral 10 denotes an opening opened in the upper part of the printer B. At the inner edge of this opening 10, as shown in FIG. 4, holding side parts 12 having a curved part 11 at one end are provided facing each other.

Further, on the inner surface of the front device of this opening 10, two protruding pieces 13 are provided that lock the elastic extension portion 8 when the lid member 4 is attached.
is installed protrudingly.

Next, the operation of attaching and detaching the cutter-equipped lid member 4 to and from the device will be explained.

By forcibly inserting the cutter-equipped lid member 4 into the opening 10 of the device 1 with the elastic extension portion 8 downward and the entire body inclined, the cutter-equipped lid member 4 is inserted as shown in FIGS. 1 and 2. It is fixed to the device 1 in the fitted state shown in the figure.

To be more specific, the cover member 4 with a cutter is placed in a posture with the elastic extension part 8 facing down and the entire body inclined by approximately 30 to 45 degrees, and the extension part 8 is placed first in the direction of the dotted line arrow shown in FIG. 4. After the stepped locking part 5 is forcibly inserted into the space above the curved part 11, the rear part 15 of the cutter member 4 is pushed down to move the cutter member 4 into the second position. It fits within the opening 10 as shown.

In this fitted state, the cutter-equipped lid member 4 is supported by the pair of holding sides 12 on both sides of its lower surface.

In addition, in the front-rear direction, the elastic extension part 8 is pressed and locked to the projection piece 13, and the rear part 15 is locked to the frame part 1a of the device 1.

Further, the step-like locking portion 5 and the locking piece 9 are configured so that the locking member does not easily come off upward.

Next, when removing the cutter-equipped lid member 4 from the device 1,
The member 4 is pushed and moved rightward in FIGS. 1 and 2 until the locking piece 9 is disengaged from the frame 1a.

At this time, the elastic extension part 8 and the projection piece 13 are in a locked state, but since the elastic extension part 8 is elastically deformed, the above operation is not hindered.

Therefore, with the locking piece 9 disengaged from the frame 1a, it is lifted from the rear portion 15 and the cutter-equipped lid member 4 is pulled out from the opening 4.

As explained above, according to the present invention, the lid member can be attached to and detached from the attachment part with one touch without screwing or pivoting, so that attachment and detachment work is easy and the number of parts can be reduced.

Therefore, there is a practical effect that maintenance and inspection of the internal mechanism, removal of paper jams, and replacement of the lid body itself for replacing the cutter can be easily performed.
