Abstract

PURPOSE:To facilitate reading with a miniature reading device by setting this reading device consisting of an image sensor, etc. on a shift stage and reading an original at an original reading part by means of a printer and with operations of a lamp, etc. CONSTITUTION:A cassette 7 is set on a moving table 10, and an original 20 is inserted through its feed slit 19 and set to a platen 15. When a read switch (not shown in the figure) is operated, the table 10 moves to the left position with its head set up. Therefore a rack gear 11 is not connected to a hub 9 via a gear mechanism. Then the reading parts on the original which are illuminated successively by a lamp 3 according to the shift of the table 10 are read by a photodetecting part of an image sensor 1. When the reading is through with a line, the table 10 is reset to the left edge to feed paper. Then the reading is carried out in the same way. Thus the characters, graphics, etc. on the original 20 are read.

Description

[Detailed Description of the Invention] [Technical Field] +Sex 111. The present invention relates to a reading device for reading 1 copper 1 A storage value 9 solid, etc.

[Technical background of the invention and its shortcomings]

Recently, technological advances in personal computers have been remarkable, and products with high performance and relatively low prices have become available, so not only some enthusiasts but also general consumers are purchasing them, and it has become a kind of trendy phenomenon. It shows.

However, even if you have purchased a computer, you cannot fully use it unless you master a programming language such as BASIO, and the reality is that many computers are left unused.

On the other hand, in proportion to the increase in sales of personal computers, the sales of printers connected to personal computers are also increasing, and it is expected that a large percentage of computer users will own printers.

Under such current circumstances, this printer is used to install an image sensor, etc. on the movable table on which the thermal head is installed, and to detect the +-lightning and M shadow of the original set on the platen. A proposal has been made to make the personal computer easier to use by making it possible to display characters on the τcomputer 110R1', thereby eliminating the need to operate the computer's keys to draw characters, etc. on the CRT.

However, in this proposal, when printing (when used as a printer), a thermal head is installed on a moving table, a cassette containing an ink tape for thermal paper is set on the moving table, and printing is performed. On the other hand, when reading a document, the thermal head and cassette are removed from the moving table, and an image sensor, etc. is installed on the moving table. The drawback was that it became difficult to use.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a reading device that solves these drawbacks and can read a document with simple operations without attaching or removing a print head such as a thermal head.

[Key points of the invention]

The present invention installs a reading means on the movable base so that the printing gutter fixed on the movable base does not interfere with reading the document on the platen, and illuminates the document reading section to operate the printer. This was used to read manuscripts.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to FIGS. 1 to 3. First, Figure 1 shows an overall perspective view, and the frame indicated by the broken line in the center of the drawing has almost the same shape as the cassette in which the thermal transfer ink tape of a thermal transfer printer is loaded, and the frame includes the image sensor 11 lens barrel 2, and the original. It shows the outer shape of a cassette 7 in which a lamp 3 for illumination and the like are arranged. 8 is moving platform 1
0 is a thermal head fixed with screws etc. 9 is a knob for feeding the thermal transfer ink tape, and when an ink tape cassette (not shown) without thermal paper is set on the moving table 10, the ink tape is wound. There is a gear mechanism (not shown) that connects with the rolling hub 9 (underneath the moving base 10, which is designed to fit with the reel shaft), and when printing, the moving base 10 moves its head down, As the moving table 10 moves on the guide shaft 12 by engaging the gear mechanism with the rack gear 11, the hub 9 also rotates, and the reel shaft (not shown) around which the thermal transfer ink tape is wound rotates. It is designed to send out ink tape. Further, 13 is a feeding wire for the moving table 10, 14.14
1 is a pulley that supports the feeding wire 3; 15 is a buzzer ten; 1
6 is a motor shaft, 17 is a paper feed gear, 18 is a manual paper feed knob, and 19 is a paper supply port.

Next, in the 21st ffl, the image sensor etc. are placed on the moving platform 10.
It is an enlarged perspective view of the cassette 7 installed on the top with the cassette 7 interposed therebetween, and the outer shape of the cassette 7 is shown with a broken line.
The cassette 7 has an escape hole 7α, and a drive circuit component (not shown) for driving the image sensor is mounted in the cassette 7. A printed wiring board 4 having a connector 5 is inserted into the lens barrel 2. A lamp 3 for illuminating a document having a lens portion is provided in front of the image sensor 1, and a connector 5
One end contacts the 7 lexiple connector (not shown) provided on the moving table 10 when the 17" part d-1 puller cassette 7 is set. The cassette 7 is connected to a reading control circuit (not shown).The cassette 7 also has a document reading window 7b opened therein.

FIG. 3 is a partially sectional plan view showing the arrangement relationship of the image sensor 1, lamp 3, thermal head 8, document 20, etc., and the lens barrel 2 into which the image sensor 1 is inserted is mounted on a movable table during reading. The reading unit 20α on the original 20 is placed in a position where it is not obstructed by the thermal head 8 fixed to the image sensor 1. The image is formed on the light receiving section 1h. Further, the lamp 3 is arranged to illuminate the reading section 201Z.

A 16-bit MO8 type line sensor is used as the image sensor l, and an f
=s inn, F 1. A bright single lens with a wide angle of o is used. By using such an optical lens, the lens barrel 2 can be made smaller and lighter, and can be formed to have a length of about 30 mm and an outer diameter of IQxi. Therefore, it could be accommodated sufficiently in the cassette 7 of 40 x 60 x 15 mm.

Next, the operation will be explained. If there is a thermal ink tape cassette for use as a printer on the movable table 10, first remove it and set the cassette 7 on the movable table 10. Then, the original 20 is inserted through the paper supply port 19 and set on the platen 15.

When a reading switch (not shown) is operated, the movable table 10 moves to the Baum position (left end in FIG. 1) and heads up. Therefore, the rack gear 11 and the knob 9 are not coupled via a gear mechanism. In this way, as the movable valley 10 moves, the light receiving section 1h of the image sensor 1 reads the reading section 201Z on the document 20 that is illuminated by the lamp 3 one after another. When one line is completed, the movable table 10 returns to the left end, feeds the paper, and reads the paper again in the same manner. By repeating this process, we are using a device that can feed a 20-inch document (n is the number of pulses that move the motor), and the paper is fed at a speed of 7 inches with n = 2. Since the image is read by the light receiving section 1b (in the direction perpendicular to the direction), the resolution in the vertical direction is 5.67 lines per line, and since the head is moved in increments with n = 1, the image sensor is 0.17
It moves 6w1 at a time and reads one line. When one line is read, the paper is advanced one inch and the next line is read in the same way. Note that if a printer capable of reciprocating printing is used, reciprocating reading becomes possible and reading can be performed at higher speed.

Further, in this embodiment, an image sensor is installed in the cassette 7.
Although it is of course not necessary to use a cassette, the use of a cassette has the advantage of being easier to handle and allowing a quick transition from printing to reading.

In this embodiment, a thermal transfer printer using a thermal head is used as a print head, but other printers such as an optical printer using an LIJD array may be used.

〔Effect of the invention〕

As explained above, the present invention, when reading a manuscript,
A reading means such as an image sensor is installed on the movable base so that the print head fixed on the movable base does not get in the way, and the document reading section is illuminated with a light emitting means such as a lamp, making operation easy. It was possible to provide a small and inexpensive reading device that can read documents using a printer.
