Description

[Detailed Description of the Invention] The present invention relates to a keyboard arrangement structure for an office processing machine incorporating a small electronic computer.

FIG. 1 is a side view showing an example of the arrangement structure of a conventional keyboard of this type, and FIG. 2 is a plan view of the keyboard shown in FIG. 1.

In these figures, 1 is a main body of an office processing machine, and inside this main body 1, a small-sized electronic computer and a display device connected to this small-sized electronic computer are housed. 2 is a cathode ray tube constituting the display device. Reference numeral 3 denotes a keyboard disposed in front of the main body 1, whose tip 4 is formed into a protruding shape including a tapered portion 5, and is opposed to a lower portion 6 located below the cathode ray tube 2 of the main body 1. ing. For example, as shown in FIG.
It also has a book-style mat section 14 in which a plurality of data keys 13 are arranged. As shown by arrow 15, this mat portion 14 is
It's starting to look like a two-page spread. Further, the date key 8, numeric keypad 9, send key 10, reset key 11, specific key 12, and data key 13 of the keyboard 3 can output command signals to, for example, a small computer built in the main body 1. It's becoming like that. In addition, 16 is keyboard 3
The heat dissipation hole formed in the tip 4 of the keyboard 3
The heated air inside is discharged to the outside from this heat radiation hole 16. Further, 17 shown in FIG. 1 is a table on which, for example, the main body 1 and the keyboard 3 are placed.

By the way, the conventional arrangement structure in which the keyboard 3 is arranged in this manner has the following disadvantages. In other words, arrow 1 in Fig. 1 is displayed on keyboard 3.
When the pressing force indicated by 8 is applied, the keyboard 3 may slide on the table 17.
If the pressing force is large, for example, if the operator of this office processing machine inadvertently pushes the keyboard 3 strongly in the direction of the main body 1, the keyboard 3
The tip 4 of the keyboard 3 tends to collide with the lower part 6 of the main body 1, and as a result, the lower part 6 of the main body 1 or the tip 4 of the keyboard 3 may be damaged.
Generally, heat is generated in the main body 1 as a result of the operation of devices such as an electronic computer and a display device built into the main body 1, and this heat has a negative effect on the performance of the devices. In the past, this heat tended to accumulate particularly in the lower part 6 of the main body 1, but since the heat radiation area of this lower part 6 was small, a sufficient heat radiation effect could not necessarily be obtained.

The present invention was developed in view of the actual state of the prior art, and its purpose is to minimize the collision between the tip of the keyboard and the lower part of the main body, and to reduce the accumulated heat in the lower part of the main body. It is an object of the present invention to provide a keyboard arrangement structure that can provide good release.

Hereinafter, the present invention will be explained based on the drawings. FIG. 3 is a side view showing an embodiment of the keyboard arrangement structure of the present invention. In this figure, the same components as those shown in FIGS. 1 and 2 are designated by the same reference numerals.

In FIG. 3, reference numeral 19 denotes a recess formed in the lower portion 6 of the cathode ray tube 2 provided on the front surface of the main body 1, and has a tapered portion 20 that fits into the tapered portion 5 of the tip portion 4 of the keyboard 3. Then, the tip portion 4 of the keyboard 3 is attached to the tapered portion 20 of this recessed portion 19.
The keyboard 3 is arranged so that the tapered portion 5 of the keyboard 3 contacts the keyboard 3. Note that the configuration of the keyboard 3 is the same as that described above.

With the keyboard arrangement structure configured in this way, it is possible to inadvertently put arrow 2 on keyboard 3.
When a pressing force indicated by 1 is applied in the direction of the main body 1, the tapered portion 5 of the tip 4 slides on the tapered portion 20 of the recess 19 of the main body 1, thereby causing the tip 4 of the keyboard 3 to slide. is lifted as illustrated by the arrow 22, the leg 23 located at the front of the keyboard 3 is moved upwardly away from the table 17, while the leg 24 located at the rear of the keyboard 3 is lifted as indicated by the arrow 25. , it is pressed in the direction of the table 17. Therefore, the pressing force applied to the keyboard 3 as shown by the arrow 21 is the frictional force caused by the sliding between the tapered part 5 of the tip 4 of the keyboard 3 and the tapered part 20 of the recess 19 of the main body 1. and,
This is absorbed by the frictional force between the legs 24 of the keyboard 3 and the table 17. As a result, movement of the keyboard 3 in the direction of the main body 1 is suppressed to a minimum,
This prevents a collision between the keyboard 3 and the main body 1.

Further, since the tapered portion 20 of the recess 19 of the main body 1 and the tapered portion 5 of the tip portion 4 of the keyboard 3 are brought into contact with each other, the accumulated heat generated in the lower portion 6 of the main body 1 is absorbed by the tapered portion 20, 5 to the keyboard 3. Therefore, this keyboard 3
Heat can also be radiated from the surface.

In addition, if there is a step on the table 17 and the main body 1
If there is a slight difference between the installation height position of the keyboard 3 and the installation height position of the
It is sufficient to move it slightly toward or away from the main body 1 from the state shown in the figure. By doing so, the keyboard 3 can be placed while the tapered portion 20 of the main body 1 and the tapered portion 5 of the keyboard 3 are kept in contact with each other.

As described above, the keyboard arrangement structure of the present invention has a structure in which a concave portion having a tapered portion that fits the tapered portion of the tip of the keyboard is formed in the main body of the processing machine equipped with the keyboard. Therefore, if an inadvertent pressing force is applied to the keyboard in the direction of the main body, the tapered part of the keyboard will move on the tapered part of the concave part of the main body, thereby preventing the keyboard from colliding with the main body. Therefore, it is possible to prevent damage to the keyboard or main body due to such pressing force. In addition, since the tapered part at the tip of the keyboard is in contact with the tapered part in the concave part of the main body, the heat generated in the lower part of the main body can be transferred to the keyboard, and the heat can be transferred to the keyboard through the keyboard. It is also possible to dissipate heat, thereby eliminating the negative effects of accumulated heat in the equipment built into the main body, and also having the effect of ensuring stable performance.
