Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a pattern reading device for paper sheets, which is used for inputting information into, for example, an electronic computer.

BACKGROUND OF THE INVENTION In recent years, electronic computers are efficiently and automatically processing a wide variety of documents (hereinafter referred to as paper sheets) that have increased in volume.

This electronic computer requires an input device that converts the numbers and characters written on paper sheets into electrical signals and inputs them. Input devices include card readers or tape readers that use a key puncher to punch a card or paper tape and convert it into electrical signals, and optical readers that use light to convert numbers and characters on paper sheets into electrical signals that are read by a recognition circuit. There is a type pattern reading device. However, card readers or tape readers require a specialist such as a key puncher, and have the disadvantage that it takes time to input information. On the other hand, optical pattern reading devices tend to be used frequently because they are easy to operate and have a short processing time.
By the way, in this type of pattern reading device, paper sheets are sent one by one onto a conveyance path, and a reading unit installed opposite to this conveyance path reads the information written on the sheets moving along the conveyance path. I'm trying to read the patterns that have been created.

However, with such a configuration, a conveyance path having a length several times the length of the paper sheets is required, and the length of this conveyance path increases the size of the device. Furthermore, the transport path requires a complicated mechanism for correcting the skew of the paper sheets and detecting the leading edge of the moving paper sheets. Furthermore, when paper sheets are moved along a long conveyance path, jams are likely to occur, leading to accidents such as equipment failure and damage to the paper sheets. This invention was made based on the above-mentioned circumstances, and its purpose is to read the pattern written on the stopped paper sheet by moving the reading section, thereby eliminating the need for a long conveyance path or a complicated mechanism. To provide a paper leaf pattern reading device capable of reading paper leaf patterns without using paper sheets.
It is in.

J Hereinafter, one embodiment of the present invention will be described based on the drawings.

In the figure, 1 is the main body of the reading device. An insertion/removal port 3 is formed in one of a pair of opposing side plates 2d and 2b of the main body 1,
A discharge port 4 is formed on the other side. A stacker 5 is inserted into the inner bottom of the main body 1 so as to be freely inserted and removed from the insertion/removal port 53. This stacker 5 includes a casing 6 formed in a substantially box shape with an open top surface and one side, and a mounting plate 8 provided on a bottom plate 6a of the casing 6 by a soft mechanism 7 so as to be movable up and down. On this mounting plate 8, many plates of paper sheets p are accumulated. The lift mechanism 7 operates in conjunction with a detector (not shown), and when this detector detects the height position of the uppermost sheet p placed on the placement plate 8, the lift mechanism 7 performs a lifting operation. is starting to stop. Further, a feed roller 9 is arranged opposite to the top surface of one end of the paper sheet p placed on the placement plate 8. The feed roller 9 is rotatably supported by the main body 1 with shafts 9a and 9b protruding from both end faces thereof, and one shaft 9a extends into a drive chamber 10 provided adjacent to the main body 1. I'm letting it come out. A driven pulley 11 is attached to the shaft 9a facing the drive chamber 10.
A drive pulley 13 is fitted onto the driven pulley 1 and the shaft 12a of the motor 12 disposed in the drive chamber 10.
A belt 14 is stretched between the two. The feed roller 9 is driven to rotate in the direction of arrow a by the motor 12, and feeds out the paper sheets p on the mounting plate 8 one by one. Further, a guide plate 15 is provided in the main body 1 to guide the paper sheets p sent out from the mounting plate 8 to the discharge port 4. 15 and is adapted to be accumulated on a pedestal 16 provided outside the main body 1 facing the discharge port 4. Also,
In the upper part of the main body 1, two rails 17, 17 are provided between a pair of side plates 2d, 2b facing each other along the longitudinal direction of the main body 1.
is constructed, and an optical reading unit 20 is mounted on the rails 17, 17, each having a drive wheel 18 and a plurality of support wheels 19 on both end faces. The rails 17, 17 are built in by a built-in drive source that drives the drive wheels 18, 18.
It is now possible to travel back and forth along the route. Next, the operation of the above configuration will be explained. First, when the stacker 5 is pulled out from the main body 1 and paper sheets p are placed on its placement plate 8, the stacker 5 is inserted into the main body 1, the software mechanism 7 is activated, and a detector (not shown) is activated. This mounting plate 8 is raised until it detects the paper sheet p on the uppermost surface of the mounting plate 8.
Next, when a reading start signal is input, the reading unit 20 is driven, and the reading unit 20 moves from one end of the paper sheets p stacked on the stacker 5 to a position facing the other end of the rail 17, 17 and reads the pattern written on the paper sheet p. Then, at the same time as the reading unit 20 finishes reading the pattern written on the paper sheet p, the feed roller 9 is rotationally driven and the paper sheet p is ejected to the receiving table 16. During this time, the reading unit 20 runs on the rails 17, 17 in the opposite direction to the previous position and returns to the initial position, and the read paper sheet p
After completion of ejection, the paper travels again and repeats the operation of reading the pattern written on the topmost paper sheet p accumulated in the stacker 5. Therefore, according to such a configuration, since the reading section 20 moves and reads the pattern written on the paper sheet p, the reading can be performed without transporting the paper sheet p. Note that the present invention is not limited to the above-mentioned embodiment; for example, the mechanism for discharging paper sheets from the stacker is not limited to a feed roller, but may be a means that sucks paper sheets and sends them out. Good too.

Further, the reading section may be moved back and forth by a driving source such as a cylinder. Furthermore, a guide plate provided within the main body is not necessarily required. As described above, the present invention moves the reading section to read the pattern of paper sheets placed on the placement plate, and then ejects the paper sheets from the placement plate. There is no need to transport paper sheets through a long transport path.

Therefore, there is no need for a mechanism to correct the skew of paper sheets or detect the leading edge of moving paper sheets.
The device can be made smaller and simpler. Furthermore, since there is no possibility of accidents such as paper sheets being conveyed becoming jammed in the conveyance path as in the past, this system has great practical effects such as improving the reliability of the apparatus.
