Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item input device that is provided with a plurality of item sheets that define a large number of item keys, and that makes it possible to input a large number of item names by changing the vertical position of the item sheet. , more specifically,
The present invention relates to a sheet file attaching/detaching mechanism for attaching or removing a sheet file to or from a drum.

A multi-item input device has an item sheet that defines each item key located below a keyboard panel in which many item keys are arranged in a matrix, and by operating a desired item key, the item key is selected. The coded information corresponding to the coded information is applied to the data processing device, and the data corresponding to the coded information is read out from the item name table corresponding to the item sheet led directly under the item key.

Therefore, not only can different data be read by operating different item keys, but also different data can be read by changing the item sheet even if the same item key is operated. It is possible to input a large number of items determined by the product of the number and the number of item sheets.

In such a multi-item input device, it is necessary to be able to easily change the vertical position of the item sheet, so an item sheet file consisting of multiple item sheets is attached to a drum that can be rotated in forward and reverse directions. It is said that Furthermore, if the multi-item input device is used for a different purpose, it is necessary to replace the item sheet, so the item sheet file can be removed from the drum.

Conventionally, in order to satisfy these requirements, the seat file attachment/detachment mechanism shown in FIGS. 8 and 9 has been adopted. That is, a cut-out recess 23 is provided at a predetermined position on the circumferential side of the drum 6 around which the item sheet file 5 is wound, and a hook-shaped hook 24 is provided in the center of the cut-out recess 23. An engaging portion 25 that engages with the claw 24 is provided at the base end.

Therefore, by inserting the item sheet file 5, the engaging portion 25 is brought into contact with the notch recess 23, and in this state, the drum 6 is driven to rotate in the item sheet file winding direction (counterclockwise direction in the figure). Then, the claw 24 engages with the engaging portion 25 and the item sheet file 5 can be wound up. In addition, when removing the item sheet file 5, the drum 6 is reversed, the drum 6 is stopped when the claw 24 is disengaged from the engaging portion 25, and the item sheet file 5 is pulled outward. The item sheet file 5 can be removed by.

The item sheet file 5 can be installed and removed in the manner described above.
At the time of inserting the item sheet file 5,
Since the claw 24 and the engaging portion 25 are spaced apart, the engaging portion 2
This method requires a member such as a magnet to hold the sheet file in a predetermined position, which has drawbacks such as not only complicating the sheet file attachment/detachment mechanism but also making it expensive. Furthermore, since the item sheet file 5 is removed when the claw 24 and the engaging portion 25 are completely disengaged, the amount of the item sheet file 5 pushed out due to the reverse rotation of the drum 6 increases, and the item sheet file 5 is Not only is there a risk that the free edge may be damaged if it hits the gap between the housing of the multi-item input device and the keyboard panel, but the shape of the claw 24 must be bent to ensure reliable engagement. Moreover, since the item sheet file itself has flexure, it has the disadvantage that it is difficult to remove the item sheet file 5 by holding it by hand.

In the present invention, an engaging part guide surface is formed next to the engaging surface of the claw with the engaging part, and the angle between the item sheet file insertion surface and the engaging surface is 90 degrees or less.
By setting the angle to 110 degrees, the item sheet file can be attached and detached with a simple operation of inserting the item sheet file and pulling it, thereby solving the above-mentioned drawbacks. This will be explained in detail with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional side view showing a multi-item input device equipped with a sheet file attachment/detachment mechanism of the present invention, in which a transparent keyboard panel 1 with a large number of item keys arranged in a matrix is attached to a housing 2 of the multi-item input device. A guide plate 3 is provided below the keyboard panel 1, and the space between the keyboard panel 1 and the guide plate 3 is used as a guide space 4 for guiding the item sheet file. , a drum 6 around which an item sheet file 5 consisting of a plurality of opaque item sheets 13, 13, . . . is wound is provided, and rollers 7,
8, 9, 10, 11 are provided, and rollers 7, 8, 9,
Of the endless belt 12 made of an elastic material such as rubber stretched between 10 and 11, the portion located between the rollers 7 and 11 closest to the guide space 4 is pressed against the side of the drum 6 that is separated from the guide space 4. I'm letting you do it.

By connecting the drum 6 to a permanent magnet type pulse motor (not shown), it can be rotated in forward and reverse directions, and the rollers 7, 8, 9, 10, 11
is connected to the pulse motor to form an endless belt 12.
However, at the pressure contact portion with the drum 6, it runs in the same direction and at the same speed as the circumferential surface of the drum 6.

The keyboard panel 1 is made of a transparent substrate such as a glass plate, and item keys such as touch keys formed by vapor-depositing contacts are arranged on the top surface of the keyboard panel 1.

The configuration of the sheet file attaching/detaching mechanism, which is the most important feature of the present invention, is as follows.

FIG. 2 is an enlarged longitudinal sectional side view showing the item sheet file attachment/detachment mechanism, showing the claw 14 provided at a predetermined position on the drum 6, the engaging portion 15 provided at the base end of the item sheet file 5, and the item sheet file attaching/detaching mechanism. Item sheet file guide 16 that guides 5 to the outside of the housing 2
It is composed of.

The pawl 14 has a substantially rectangular groove formed in a predetermined position on the outer peripheral surface of the drum 6, and has one inner surface formed as an abutting surface 17 for abutting the engaging portion, and the other inner surface. A lower half of the groove is formed as a hanging surface 18 that engages with the engaging portion 15, and a notch that communicates with the groove is provided in the upper half of the other inner surface, and the bottom surface of the notch is formed as a hanging surface 18. It is formed on a continuous guide surface 19 for guiding the engaging portion. and,
Item Insertion direction of sheet file 5 and hanging surface 1
The angle θ with respect to 8 is set within the range of about 90 degrees to 110 degrees.

The engaging part 15 consists of a frame having a through hole into which the claw 14 can be inserted, and by bending the central part at a predetermined angle, the distal edge protrudes toward the claw 14.
This facilitates engagement with the claw 14.

The item sheet file guide 16 is located in the guide space 4.
It is made up of a plate that is movable up and down at the upper end near the drum.By rotating upward, the guide space 4 is opened, and by rotating downward, the guide space 4 is closed, and at the same time, it is placed at a predetermined position on the upper surface of the casing 2. The item sheet file inlet/outlet 20 provided in the is opened.

The operation of the multi-item input device configured as described above is as follows.

When installing the item sheet file 5, first energize a permanent magnet type pulse motor (not shown) to rotate the drum 6, stop the drum 6 at a position where the pawl 14 is close to the roller 11, and then The sheet file guide 16 is rotated downward to open the item sheet file loading/unloading port 20.

Thereafter, it is only necessary to hold the item sheet file 5 and insert it toward the drum 6 from the item sheet file inlet/outlet opening 20, and the tip edge of the engaging portion 15 slides toward the abutting surface 17 while keeping it in contact with the guide surface 19. (See Figure 3). Then, when it is sensed that the engaging portion 15 has come into contact with the abutment surface 17 and the hand is released from the item sheet file 5, the item sheet file 5 is supported using the edge of the item sheet file inlet/outlet 20 as the fulcrum 21. The claw 14 and the engaging portion 1 are rotated upward by the balance around the fulcrum 21 of the item sheet file 5 and the elasticity of the item sheet file 5.
5 can be reliably engaged (see FIG. 4).

Next, by rotating the drum 6 in the item sheet file winding direction (counterclockwise in the figure) by energizing the permanent magnet type pulse motor, the item sheet file 5 can be wound onto the drum 6 (fifth (see figure). Finally, the item sheet file guide 16 is rotated upward to close the item sheet file inlet/outlet 20 and open the guide space 4, thereby completing the item sheet file mounting operation.

When selecting a desired item sheet 13, the item sheet file 5 is completely wound up,
It is only necessary to further rotate the drum 6 in the counterclockwise direction, and the free edge of each item sheet 13, 13, . . . can be sequentially released from the pressure by the endless belt 12 near the roller 7.

Then, by detecting that the free edge of the desired item sheet 13 is released, the drum 6 is stopped, and then reversed, all the item sheets are removed with the desired item sheet 13 at the top. 13,13
... can be guided to the guide space 4.

When removing the item sheet file 5, first rotate the item sheet file guide 16 downward to open the item sheet file inlet/outlet 20,
All you have to do is rotate the drum 6 in the clockwise direction.
The item sheet file 5 released from the pressure by the endless belt 12 in the vicinity of the roller 11 is guided upward by the item sheet file guide 16, and can be sent out from the item sheet file inlet/outlet 20 to the outside of the multi-item input device. Then, when the amount of wrapping of the item sheet file 5 around the drum 6 becomes approximately equal to one turn, the permanent magnet type pulse motor is stopped. Therefore, at this point, the free ends of the item sheets 13, 13... do not reach the gap 22 between the housing 2 and the keyboard panel 1,
There is no risk of damage to the item sheets 13, 13, etc. (see Figure 6).

Thereafter, the item sheet file 5 may be pulled by hand, and the drum 6 rotates approximately one rotation in the clockwise direction depending on the amount of pulling of the item sheet file 5 (see FIG. 7).

Then, if the item sheet file 5 is further pulled, the angle θ between the hooking surface 18 of the claw 14 and the insertion direction of the item sheet file 5 is set to about 90 degrees to 110 degrees, and the item sheet file 5
Due to its elasticity, the engaging portion 15 and the claw 14 can be disengaged without requiring extra pulling force or extra operations, and after that, the item The sheet file can be taken out to the outside of the multi-item input device through the sheet file inlet/outlet 20.

Note that the drum 6 is driven to rotate clockwise while the tensile force of the item sheet file 5 is applied, but since it is connected to a permanent magnet type pulse motor, the engaging portion 15 and the claw As soon as the engagement with 14 is released, the rotation is stopped and no rotation occurs due to inertial force. Therefore, the drum 6 has the engaging portion 1
5 and the claw 14 are disengaged, and the sheet file 5 is stopped in preparation for the next attachment of the item sheet file 5.

The embodiment described above uses a permanent magnet type pulse motor to prevent rotation of the drum 6 due to inertial force, but the present invention is not limited to this embodiment at all, and for example, braking means may be provided as appropriate. In particular, it may be configured to prevent rotation of the drum 6 due to inertial force, and other design changes may be made as appropriate.

As described above, in the present invention, the claw provided at a predetermined position on the peripheral side wall of the drum is configured with a flat engaging part guide surface and a flat hooking surface. The claw can be engaged with the engaging part of the item sheet file by simply removing your hand from the file, and the angle between the hanging surface and the insertion direction of the item sheet file is approximately 90 degrees to 110 degrees. Therefore, not only can the engagement between the engaging portion and the claw be reliably maintained when the item sheet file is attached, but also the engagement between the engaging portion and the claw can be released by simply pulling the item sheet file. Furthermore, since the drum can be prevented from rotating due to inertial force, the drum will stop at the position where the engaging part and the claw are disengaged, and the next sheet file installation operation can be started immediately. It has unique effects such as being able to perform.
