JPS5840420Y2 - sliding keyboard mask - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sliding keyboard mask used in terminal devices such as keyboard printers having a horizontal inserter section.

For example, a keyboard printer is provided with a group of keyboard keys (first group of keys) for typing numbers and a group of function keys (second group of keys) for determining functions.

In this case, a keyboard mask is used that covers a group of keyboard keys or a group of function keys in order to prevent erroneous operations such as accidentally hitting a function key when only numeric keys are to be pressed.

However, since conventional keyboard masks are simply placed on the keyboard section or function section, there have been problems such as loss or damage due to falling.

The present invention is intended to solve the above-mentioned problems especially in terminal equipment having a horizontal inserter section, and is designed to eliminate the risk of loss or falling, and also to serve as a guide when inserting a medium into the inserter section. The purpose is to provide a sliding keyboard mask that can be used.

Embodiments of the invention will now be described with reference to the drawings.

Fig. 1 is a side view showing a sliding keyboard mask according to the present invention used in a keyboard print having an inserter section, Fig. 2 is a perspective view showing details of this sliding keyboard mask, and Fig. 3 is the same plane. In the figure, 1 is the operation unit housing, 2 is the keyboard section with one key group 3, 4 is the function section with keys 5, 6 is the horizontal inserter section, and 7 is the sliding keyboard mask. be.

The sliding keyboard mask 7 has a pair of guide plackets 8.
and a keyboard mask 9.

As shown in detail in FIG. 4, the guide bracket 8 has a guide groove 13 formed by continuously forming concave grooves 11 and 12 at both ends of a linear groove 100, and has grooves 13 on both sides of the key group 5 of the function section 4. The operation unit housing IK is fixed.

The keyboard mask 9 is shaped to cover the key group 3 of the keyboard section 2 or the key group 5 of the function section 4, and shafts 14 that fit into the grooves 13 are attached to both sides thereof.

FIG. 1 shows a state in which the shaft 14 of the keyboard mask 9 is engaged with the concave groove 11 of the guide groove 13 and positioned, and in this state, the keyboard mask 9 covers the key group 3.

In this case, the first group of keys 5 of the function section 4 can be operated, and furthermore, the erroneous operation of the first group of keys 3 of the keyboard section 2 can be prevented during this operation.

When it becomes necessary to operate the key group 3, the key group 3 can be operated by opening the keyboard mask 9 using the concave groove 11 as a fulcrum, as shown in FIG.

When you want to cover the key group 5 of the function section 4,
The keyboard mask 9 is lifted to separate the shaft 14 from the concave groove 11, the shaft 14 is guided to the linear groove 10, the keyboard mask 9 is pushed in, and the shaft 14 is engaged with the concave groove 12.

FIG. 6 shows this state, in which the keyboard mask 9 covers the key group 5.

In this case, the first group of keys 3 of the keyboard section 2 can be operated, and at the same time, erroneous operation of the first group of keys 5 of the function section 4 can be prevented during this operation.

When it becomes necessary to operate the key group 5, the key group 5 can be operated by opening the keyboard mask 9 using the concave groove 12 as a fulcrum, as shown by the dotted line in the figure.

In this state, the upper surface of the keyboard mask 9 forms a road surface with the medium guide surface 15 of the inserter section 6, and serves as a table for guiding the medium when inserting the medium into the inserter section 6.

In any of the above cases, the keyboard mask 9 can be used as a work place for stamping, writing, etc.

Note that if a protrusion 16 is provided on the front upper surface of the keyboard mask 9, a ballpoint pen or the like placed on the keyboard mask 9 can be prevented from falling.

As described above, according to the present invention, it is possible to selectively easily and reliably cover a group of keys in the keyboard section or a group of keys in the function section to prevent erroneous operations, and the keyboard mask is fixed to the operation section housing. It was lost because it was supported by a guide bracket that was removed.

In addition to solving the problem of falling, the keyboard mask positioned to cover the group of keys in the function section has various excellent effects such as playing the role of guiding the medium when inserting it into the horizontal inserter section. It is possible to play.
