DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a multi-item input device that is provided by stacking a plurality of item sheets that define a large number of item keys, and allows the item sheets to smoothly run directly under a keyboard panel. Another object of the present invention is to easily lead out the item sheet to the outside of the multi-item input device when exchanging the item sheet.

In the multi-item input device, a large number of item keys are arranged in a matrix, and each item key is defined by guiding a desired item sheet directly under the item key. Then, by operating a desired item key, coded information corresponding to the item key is applied to the data processing device, and the coded information is input from the item name table corresponding to the item sheet led directly under the item key. Read the corresponding data.

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

Conventionally, as such a multi-item input device, the third
I had the configuration shown in the figure. That is, an upper guide plate 1 is placed below a transparent keyboard panel 1 in which a large number of item keys are arranged in a matrix.
5 to connect the keyboard panel 1 and upper guide plate 1.
5 is used as an upper space 16 for guiding selected item sheets, and a lower guide plate 17 is provided below the upper guide plate 15, and the space between both guide plates is used as a lower space for guiding the remaining item sheets. 18, and further provided in close proximity to the upper space 16 and the lower space 18, a drum 5 on which a plurality of transparent or translucent item sheets 4, 4... are wound in a stacked state, and is provided so as to surround the drum 5. An endless belt 10 made of an elastic material such as rubber and stretched between rollers 6, 7, 8, and 9 is brought into pressure contact with the side surface of the drum 5 that is separated from the spaces 16 and 18. The drum 5 is connected to a motor (not shown) to enable forward and reverse rotation, and the rollers 6, 7, 8, and 9 are connected to the motor. Furthermore, one side edges of a plurality of item sheets 4, 4, . . . are provided on the drum 5 directly or indirectly at equal intervals. Also, drum 5,
Both spaces 16,
The side surface facing directly 18 does not come into contact with the endless belt 10 and serves as an item sheet feeding section.

Note that 14 is an item sheet guide.

Therefore, when a desired item sheet 4 is to be sorted and sent to the upper space 16, the motor (not shown) is first rotated in the normal direction to rotate the drum 5 in the item sheet winding direction (counterclockwise direction in the figure). do. If the rotation of the drum 5 is continued even after all the item sheets 4, 4, . . . have been wound up, the free edges of the item sheets 4, 4, .

Here, if it is detected that the free end edge of the desired item sheet 4 is released from the pressure by the endless belt 10, the drum 5 is stopped, and then the drum 5 is reversed, only the desired item sheet 4 is removed. Upper space 16
, and the remaining item sheets 4, 4, .

By operating the item keys after selecting the desired item sheet 4 as described above, data determined by the item sheet 4 and the item keys can be read out, making it possible to select input of multiple items.

However, in the conventional device, the keyboard panel is mounted at a fairly high position, and the top surface of the keyboard panel 1 and the top surface of the drum 5 are almost on the same plane, so when guiding the item sheet 4 to the upper space, The item sheet 4 has to be curled significantly in the opposite direction to the direction when the item sheet is wound up on the drum, which gives an unreasonable deformation to the item sheet, hinders smooth movement of the item sheet, and shortens the durability of the item sheet. There are drawbacks.

Further, there are other drawbacks, such as not only is it difficult to take the item sheet in and out of the multi-item input device housing when replacing the item sheet, but also the position of the keyboard panel 1 is raised, making key operations difficult.

The present invention solves the above-mentioned drawbacks by positioning the keyboard panel at a lower level than the top surface of the item sheet winding drum, and will be described in detail below with reference to the accompanying drawings showing embodiments.

FIG. 1 is a longitudinal side view showing an embodiment of the multi-item input device of the present invention.

A guide plate 2 is provided below a transparent keyboard panel 1 in which a large number of item keys are arranged in a matrix, and the space between the keyboard panel 1 and the guide plate 2 is used as a guide space 3 for guiding item sheets. A drum 5 is provided in close proximity to a drum 5 on which a plurality of opaque item sheets 4, 4... are wound in a stacked state, and rollers 6, 7, 8, 9 are provided to surround the drum 5. , 8 and 9, the part of the endless belt 10 made of an elastic material such as rubber stretched between the rollers 6 and 9, which is closest to the guide space 3, is attached to the side of the drum 5 that is separated from the guide space 3. It is pressed into contact.

A stepped portion 12 is provided at a predetermined position of the housing 11 of the multi-item input device, so that the drum storage portion is taller.
The height of the remaining portion is made low, and the keyboard panel 1 is fixed to the short portion, and an item sheet insertion/removal opening 13 is provided at the lower edge of the stepped portion 12.

Further, by connecting the drum 5 to a motor (not shown), it can be rotated in forward and reverse directions, and by connecting the rollers 6, 7, 8, and 9 to the motor, the endless belt 10 can rotate the drum at the pressure contact portion with the drum 5. It runs in the same direction and at the same speed as the circumferential surface of No.5.

Further, one side edges of a plurality of item sheets 4, 4, . . . are provided on the drum 5 directly or indirectly at equal intervals.

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.

Reference numeral 14 denotes an item sheet guide provided directly below the item sheet loading/unloading port 13, and the item sheet guide 14 can be rotated upward to open the item sheet loading/unloading port 1.
By closing the item sheet guide 14, the item sheets 4, 4... are led to the guide space 3, and by rotating the item sheet guide 14 downward and closing the guide space 3, the item sheets 4, 4... are multi-item input. I try to lead it out of the device.

The operation of the multi-item input device configured as described above is as follows. Select the desired item sheet 4,
Position the item sheet 4 so that it is at the top,
When stacking all the item sheets 4, 4, etc. and sending them out to the guide space 3, first rotate the motor (not shown) in the normal direction to move the drum 5 in the item sheet winding direction (counterclockwise in the figure). Drive rotation. If the rotation of the drum 5 is continued even after all the item sheets 4, 4... have been wound up, the free edges of the item sheets 4, 4... can be sequentially released from the pressure by the endless belt 10. can.

Therefore, the detection means (not shown) detects that the free edge of the desired item sheet 4 is released from the pressure of the endless belt 10, and the drum 5 is stopped.
Subsequently, by reversing the drum 5, all the item sheets 4, 4, . . . can be guided into the guide space with the desired item sheet 4 positioned at the top.
Here, since the keyboard panel 1 is provided considerably below the top surface of the drum 5, the guide space 3 is located close to the bottom surface of the drum 5, and when the item sheets 4, 4... are wound up on the drum. There is no need to make the curl in the opposite direction too large, and the item sheets 4, 4, . . . can be smoothly guided into the guide space.

In addition, in the above case, item sheet guide 14
By rotating the item sheet opening 13 upward, the item sheet loading/unloading port 13 is held in a closed state.

After selecting the desired item sheet 4 as described above, by operating an item key, coded information corresponding to the item key encoded by a key circuit (not shown) is sent to a data processing device (not shown). The data corresponding to the coded information can be read from the item name table corresponding to the item sheet 4 located at the top.

In addition, when replacing the item sheets 4, 4..., the drum 5 is driven to rotate in the same manner as described above, and it is detected that the free edge of the first item sheet 4 is released from the pressure by the endless belt 10. to stop the drum 5. Then, the item sheet guide 14 is rotated downward to open the item sheet loading/unloading port 13, and the drum 5 is rotated in the opposite direction.
It can be derived externally from

Therefore, the item sheets 4, 4, . . . can be easily exchanged outside the multi-item input device.

FIG. 2 is a longitudinal cross-sectional view showing another embodiment, which differs from the embodiment shown in FIG. The only difference is that it is extended toward the drum 5, and the configuration of other parts is the same.

Therefore, compared to the embodiment shown in FIG. 1, this embodiment is able to smoothly guide the item sheets 4, 4, . It has excellent effects.

As described above, in the present invention, the keyboard panel is mounted at a predetermined position that is considerably lower than the top surface of the drum, so that the item sheet can be guided into the guide space without significantly curling in the opposite direction to the direction when the item sheet is taken up on the drum. This not only makes it possible to run the item sheet smoothly and improve item sheet sorting efficiency, but also improves the durability of the item sheet, and the key position is low and easy to operate. Furthermore, the multi-item input device has unique effects such as being able to be easily removed from the outside and replaced.
