Description

[Detailed description of the invention] The present invention relates to a multi-item information input device for inputting multi-item information to an information processing device by key operation, and in particular, it involves rolling up a plurality of page sheets with input information in a roll. The present invention relates to a multi-item information input device which can be miniaturized and which can be rotated in forward and reverse directions to select and switch desired page sheets.

As a conventional device of this type, there is a multi-item information input device disclosed in Japanese Patent Application Laid-open No. 159126/1983 published on December 15, 1974.

This is composed of a page sheet storage section, a page sheet switching mechanism section, and a keyboard section for input operations. The page sheet storage section has a roll-shaped page sheet member in which a plurality of flexible page sheets with function indications of input keys are fixed at regular intervals on the circumference of the rotation axis, and this is replaced with the main body of the device. It consists of a lever structure that accommodates it so that it can be attached and detached as much as possible. Then, when the operator presses a desired page selection key on the keyboard section, the stepping motor of the page sheet switching mechanism section is activated, and the rotating shaft connected thereto is rotated at a predetermined angle in the opposite direction to the page sheet winding direction. After the desired page sheet is rotated and the other end surface of the desired page sheet is positioned at the page sheet output port to be in the set state, the rotating shaft is then rotated in the page sheet winding direction to input the desired page sheet into the keyboard section. A function display is automatically displayed on the bottom surface of the key to provide a function display for the input key. In this state, when the operator looks at the function display and presses a desired input key, the key signal from the input key is transmitted along with the page sheet identification signal from the page selection key and the page sheet member identification signal generated when the page sheet storage section is accommodated. It is encoded and input to the information processing device as human information. By the way, in this conventional device, in consideration of the replaceability of the page sheet members, the entire page sheet storage section is constructed as a cartridge, which can be attached and removed from the main body of the device. In reality, it includes four rotating shafts for spanning the endless belt that holds the page sheet in the winding direction, and a side plate that forms the storage casing, which is heavy and large, so it must be replaced. This was troublesome and required a large amount of storage space.

Furthermore, in the past, since the page sheet storage section was located below the keyboard section, the keyboard section had to be removed before replacement, which made handling cumbersome.
The present invention aims to solve the above-mentioned conventional drawbacks and to simplify the replacement of page sheet members. The purpose of this is to fix a plurality of flexible page sheets of the same shape with input information attached to one side of a flexible base sheet with one end spaced apart from each other by a certain distance. It has a plurality of page sheet members, and a winding shaft for detachably attaching the page sheet members, which is rotated in the winding direction and the reverse winding direction of the page sheet members using an electric motor as a driving source, is provided in the main body of the device. and at least an endless belt for holding the page sheet member wound around the winding shaft in its wrapped state, and the device main body further includes an input key group consisting of a plurality of switches, a page selection key group, and a page sheet member. a keyboard portion having at least a switch exclusively for member exchange; a desired page sheet member among the plurality of page sheet members is engaged with the winding shaft from outside the apparatus main body through a page sheet member exchange port of the apparatus main body; The page sheet member is supplied so that the base sheet is wound around the winding shaft and is wound around the winding shaft by the rotation of the winding shaft, and the page sheet member is wound up so that the base sheet is wound around the winding shaft and each of the page sheets is wound on the winding shaft. The base sheet is wound in one direction with the other end exposed and overlapped with each other, and the winding diameter of the base sheet is set so that the exposed length of the other end of each page sheet is at the end of the winding where the exposed length of the other end of each page sheet is covered with the beginning page sheet. The page sheets have a constant length other than the page sheets, and only the end page sheet of the volume is set to have a longer exposure length than the other page sheets,
When the winding shaft rotates in the winding direction and the reverse winding direction in accordance with the switch operation of the page selection key group, the page sheet member in the wound state is unwound from the winding shaft and returned to the selected position. derives only the desired page sheet set in the input key group to correspond to the input key group of the keyboard section, and provides a function display to the switch of the manual key group;
When a page sheet other than the desired page sheet is guided to the guide path below the keyboard and the exchange exclusive switch is operated, the winding shaft first rotates in the winding direction to remove the first page sheet. The other end of the sheet passes through the selection position and is located in the guide path, and the other end of the end page sheet is held by the belt, and from this state the winding shaft is rotated. Rotating in the reverse winding direction, each of the page sheets is led out into the guide path, and the page sheet member is removed from the winding shaft, so that the page sheet member cannot be taken out of the main body of the apparatus. This can be achieved using a multi-item information input device characterized by being set in a possible state.

Next, the page selection operation of the above-mentioned Honda item information input device will be explained with reference to FIGS. 8 to 17.

In this figure, the same reference numerals as those mentioned above represent the same contents. First, regarding the winding operation of the page sheet member 14, the desired page sheet member 14 is first inserted into the guide passage 13 from the exchange port 4, and the base sheet 1 is rolled up.
The rear end of the winding shaft 41 is brought into contact with the winding shaft 91, and the winding is possible as shown in FIG.

Next, when the predetermined push button switch 5 of the page selection key group A corresponding to the selected page sheet 140 is pressed and switched, the stepping motor 100 is automatically driven as shown in FIG. 9, and the gear 101 is rotated in the direction of the arrow c. Then, the drive shaft 92 is rotated by a predetermined angle in the direction of arrow d via the gear 102.

Furthermore, when the drive shaft 92 rotates, the belt 93 rotates in the directions of arrows E and f, and the winding shaft 91 rotates by a predetermined angle in the direction of arrow g.

Furthermore, as the winding shaft 91 rotates, the page sheet member in the state shown in FIG. 8 is wound onto the winding shaft 91 as shown in FIG. It will be done. When the rotation of the winding shaft 91 by a predetermined angle in the g direction is completed, as shown in FIGS. 9 and 13, only the other end of the desired page sheet 140 is attached to the guide plate
It is set to a locked state at 1. Subsequently, from this state, the stepping motor 100 is automatically driven in reverse rotation 1 and the first
As shown in Figure 0, a gear 101, a drive shaft 92, a belt 93
, the winding shaft 91 rotates in the opposite direction to FIG. 9 as indicated by arrows H, i, j, k, and l.

The winding shaft 91 is in the winding direction of the page sheet member 14 (g direction)
When the desired page sheet 140 is rotated in one direction, which is the opposite direction, as shown in FIGS. 10 and 14, the desired page sheet 140 is guided in the direction of arrow m, and the other page sheet 140'''1 is guided in the direction of arrow n. When the rotation of the winding shaft 91 by a predetermined angle in one direction is completed, the desired page sheet 1 is rotated as shown in FIG.

When the other push button switch 5 of the page selection key group A is pressed from the state shown in FIG. 11, the winding shaft 91 is moved to the ninth
After automatically rotating the desired page sheet 140 by a predetermined angle as shown in the figure and winding up the desired page sheet 140 on the guide plate 75 (state in FIG. 12), the specified desired page sheet 140 of this time is in the state shown in FIGS. 9 and 13. is set.

Thereafter, the winding shaft 91 is driven to rotate in reverse as shown in FIGS. 10 and 14, and when the rotation by a predetermined angle is completed, the page of the desired page sheet 140 is selected as shown in FIG. 11. Next, the operation of exchanging the page sheet member 14 wound around the winding shaft 91 will be explained.

When replacing the page sheet member 14 in the state shown in FIG. 11, first the push button switch 5 dedicated to page sheet member replacement in the page selection key group A is switched.

Then, similarly to the above, the winding shaft 91 is automatically rotated by a predetermined angle as shown in FIG. 9, passes through the winding state (the state shown in FIG. 12), and then is set to the state shown in FIG. 15. FIG. 15 shows a state in which the other end of the first page sheet 140' has passed through the guide plate 11 and is located in the guide passage 13, and the other end of the last page sheet 140'' is locked to the shaft 94. This is because, as explained in FIG.
This can be obtained from the fact that the interval 0'' is the state in which one page sheet has been removed.Then, from the state shown in Fig. 15, the winding shaft 9.1
is reversely rotated as shown in FIG. 16, and when the rotation by a predetermined angle is completed, the page sheet member 14 is discharged into the guide passage 13 and returns to the initial winding operation state. In this state, one end of the page sheet member 14 can be led out from the exchange port 4 and removed by the operator. Next, electrical control of the Honda item information input device will be schematically explained. First,
The stepping motor 100 is controlled and driven by a motor control circuit (not shown) mounted on the printed board 73.

That is, when the push button switch 5 of the page selection key group A is switched, the motor control circuit correspondingly generates a preset positive pulse (pulse for rotating the winding shaft 91 in the winding direction g) and a negative pulse. (pulses for rotating the winding shaft 91 in the reverse winding direction 1) are continuously transmitted to the stepping motor 1.
Apply to 00. In conjunction with this, the stepping motor 100 rotates a predetermined number of steps in the forward and reverse directions to select a page or discharge a page sheet member.

On the other hand, multi-item information is output to an external device by a keyboard encoder circuit mounted on the printed board 73.

That is, when the page sheet member 14 is rolled up, the end of the base sheet 141 is introduced between the support stands 151 and 153 of the sheet detection section 15, but at this time, one set of light emitting elements 152
The identification hole 143 is detected by the light receiving element 154 and a predetermined page sheet member identification signal is generated. In addition, the other set of the generating element 152 and the light receiving element 154 detect the detection hole 144 within the range in which the winding shaft 91 rotates by a predetermined angle when the push button switch of the page selection key group A is pressed, thereby generating a predetermined page sheet identification signal. occurs. The page sheet member identification signal and page sheet identification signal are input to the keyboard encoder circuit together with the input key signal generated when the push button switch of input key group B is pressed, and the corresponding code registered in the memory in the encoder circuit is thereby inputted. The configuration is such that the specified code signal is output to an external device. As described above, the present invention has a structure in which only the page sheet member is replaced, unlike the conventional method, so that the handling property is extremely good, and an inexpensive and highly versatile multi-item information input device can be provided. Further, since the page sheet member of the present invention uses flexible page sheets of the same shape, the number of parts is small and it is advantageous in manufacturing.

Furthermore, flexible page sheets of the same shape are attached to the base sheet at regular intervals, and the exposed length of the other end of each page sheet is set depending on the winding diameter of the base sheet. The exposed length of the other end of the page sheet can be formed with high accuracy, and stable page selection and page sheet member replacement operations can be achieved.

Furthermore, in the present invention, since the keyboard section is provided with a dedicated switch for replacing the page sheet member, the operator can replace the page sheet whenever necessary, thereby providing a multi-item information input device with good operability.
