Description

[Detailed Description of the Invention] The present invention relates to a punch card display device for displaying a specific card from a group of punch cards arranged in a predetermined order.

Sources used in computer systems
Punch cards for programs, job control, etc. consist of a plurality of boards each containing a string of specific information, arranged in a predetermined order, stored in that order, and used when needed. are also supplied to the input device in that order. The so-called apatya card with a microfilm attached,
Similarly, it consists of a group of punched cards arranged in a predetermined order, and is stored in that order and machined as needed. In such a group of punch cards, those that are mis-punched,
Alternatively, if something needs to be replaced for correction, the card must be removed and replaced with another correct card in its designated position.

In such cases, the following measures have conventionally been taken.

1 Turn over the cards one by one, catch up on the text printed on the top edge of the card, and dig out the corresponding card.

2 Place a group of cards through a card reader, have a line printer print out the character print portions of each card in a predetermined order, and determine the correct position of the card from the list, or the approximate position if there are a large number of cards. Then, the corresponding card is searched among the card group.

The former work is completely manual work, and in general cases where there are a large number of cards, it takes up a lot of man-hours, and cards may be dropped during the work, or the order of the cards may be thrown out of order, so it does not pose a problem in terms of work efficiency.

Although the latter method requires less man-hours than the former method, it requires expensive peripheral equipment such as a card reader and line printer, and a computer system that requires a high amount of usage, and furthermore, the card must be removed at the end.

The present invention provides a novel punch card display device that eliminates these drawbacks.

In this invention, this purpose is approximately the thickness of the card (approximately
This is achieved by using an endless drive band with 0.6 mm) ridges at regular intervals across its width.

Punch cards in which protrusions provided at regular intervals on the surface of the driving band are stacked are arranged with the spacing between the protrusions being adjusted to expose and display the character printed portion at the upper end of each card.

When the stacked punch cards are placed on this drive band, the protrusions on the surface will be drawn out to the bottom edge of the bottom card as the drive band advances, and the appropriate inclination will be achieved.
By advancing the drive band with an inclination,
One by one, the cards at the bottom are pulled out one by one for each successive protrusion. Conversely, the same purpose can be achieved by pushing a single card into each protrusion position as the drive band advances, thereby exposing the character print portion at the upper end. A group of cards stacked in a specified order maintains that order with the character print section at the top exposed only on the drive band, and is stored in the storage position as it is, so that the specified order does not go out of order until the end. There is no fear. By recognizing the drive speed of the drive belt while the character print section is exposed and controlling the card so that the corresponding card can be replaced with a new card, the drive belt can be driven without stopping until the work is completed.

The gist of the present invention will be specifically explained below with reference to embodiments shown in the drawings.

FIG. 1 shows a perspective view of a group of punch cards 1 arranged in a prescribed order, and a character print section 3 indicating punch information of each card is printed on the upper end of each card 2.

FIG. 2A shows a part of the endless drive band 4 used in the present invention in a perspective view. It is made of a thin plate of rubber or flexible band resin material, and the surface has step-like protrusions 5 in the width direction. are formed at regular intervals, and a rough surface 6 is formed on the back surface if necessary to prevent slipping during driving. As shown in the side view in Figure 2B,
The height h of the protrusion 5 is the thickness of the card (usually about 0.6 mm)
The distance W between the protrusions 5, which is slightly smaller (for example, 0.5 mm), is formed to be slightly larger than the height of the character print portion at the upper end of the card.

FIG. 3 shows a partially sectional side view of the essential parts of an embodiment of the punch card display device according to the present invention. A group of cards 1 inserted in a predetermined order into a card box 10 arranged above.
As the drive band moves, the cards at the bottom are pulled upward one by one by the protrusion 5 on the drive band. Pressure spring 11 provided at the lower front of the card box
has one protrusion 5 for friction resistance between cards.
This helps prevent one or more cards from being drawn out in a pile.

In this way, each card rises on the slope of the drive band 4 while displaying only its character print part, moves down between the guide wheels 8 and 9, and falls due to its own weight, leaving the original card in the card storage box 12. They are stacked in the specified order. A thin plate 13 made of aluminum, for example, which is pushed up to a fixed position by a bullet on the upper side of the storage box 12, is useful for controlling the correct falling posture of a card falling under its own weight into the storage box 12.

FIG. 4 is a side view of a main part of another embodiment of the present invention, partially in cross section. At this time, the stacked card group moves from above to below on the drive band while exposing the display printed portions of the individual cards.

The card group 15 stacked in a predetermined order in the upper card box 14 is pushed by a leaf spring 16, and the step
A stopper/pressing plate 18 that moves up and down in synchronization with the drive of the drive band 17, which advances bi-step in the direction of the arrow, allows each sheet to be pushed out onto the slope of the drive band. For intermittent advancement of this drive band, a drive wheel 19 and guide wheels 20, 21, 22 are provided around the back side of the drive band.
Advantageously, a ridge is provided which meshes with the gear ring.
For example, the transparent strip-shaped holding plate 23 serves to prevent the card row from falling forward as it moves downward on the slope of the drive band 17, and if a card that should be replaced is found during visual inspection, it can be removed from the side and replaced. Can be done. The cards that have reached the lower part while remaining in a predetermined arrangement are detached from the holding plate 23 and are fallen forward and stored in the card storage case 24.

As explained above, the present invention has a simple configuration in which an endless driving band with protrusions is used, and a predetermined card can be easily exchanged from a group of punched cards stacked in a regular arrangement order, and the order can be changed. It can be stored while being retained, and its practical effects are great.
