Embodiments of the present invention will be described below with reference to the drawings. <Basic Configuration of Embodiment> FIG. 1 is a block diagram showing an example of a card type scanner according to the present invention. An image reading unit 1 for optically reading an image on a medium to be read such as paper and converting the image into an analog electric signal;
A moving amount measuring unit 2 for measuring a moving amount on the reading medium of
An image signal processing unit 3 for processing an analog image signal output from the image reading unit 1, and a reading control unit 4 for controlling the driving of the image reading unit 1 based on the movement amount of the movement amount measuring unit 2.
And a PC card unit 5 for outputting read data to an external information processing device.

FIG. 2 is a perspective view of a card type scanner according to the present invention. FIG. 3 is a perspective view in which the card-type scanner device according to the present invention is connected to the information processing device 10. The PC card section 5 has a card shape and includes the image signal processing section 3, the reading control section 4, and the PC card interface section 6, and can be inserted into a PC card slot 12 provided in the information processing apparatus 10. ing.

The image reading section 1 and the movement amount measuring section 2 are provided in the end of the PC card section 5 on the opposite side to the insertion side of the PC card section 5 into the information processing apparatus 10 and housed in a housing. When the unit 5 is mounted on the information processing device 10, it protrudes outside the information processing device 10.

FIG. 4 shows a state in which the information processing apparatus 10 and the card-type scanner are integrated to read a document to be read. The information processing apparatus 10 is portable, and has a liquid crystal display as a display unit 11 on one surface thereof. Then, the information processing apparatus 10 is brought into close contact with the document to be read while being integrated with the scanner apparatus, and the entire apparatus is manually moved to scan over the medium to be read. As a result of the scanning, the read images are sequentially displayed on the display unit 11, so that the image data is read while the read image is confirmed on the display unit 11 of the information processing apparatus 10. FIG. 5 shows the control and data flow during reading of the card type scanner according to the present invention. This example is an example of reading data for four lines. The control and data flow will be described while describing the block diagram of FIG. 1 in detail.

The image reading section 1 has a line sensor and a light source (L
An image is read with a reading medium in close contact with the reading medium using an ED or a cold cathode tube) and a lens. Turn on the light source during reading,
By causing the line sensor to start reading in response to a start signal, the amount of reflected light at each position on the sensor is converted into an electric signal and output as an analog signal.

The moving amount measuring unit 2 converts the moving amount on the reading medium into a pulse signal by an encoder and outputs the pulse signal. The image signal processing section 3 digitizes the image signal from the image reading section by an A / D conversion circuit, and further performs image processing such as binarization as necessary.

The reading control unit 4 controls the entire reading and transfers data to the information processing apparatus 10. A start signal to the line sensor is always generated during the reading period, and the line data after the image processing is stored in an internal buffer. When the movement pulse from the movement amount measuring unit 2 is detected, the image-processed line data stored in the buffer of the target line is raised by interruption to the information processing apparatus 10 and data transfer is performed. If the movement pulse is detected twice or more within one drive cycle of the line sensor, the data is transferred only once since the movement of the scanner has occurred beyond the reading performance of the scanner. If the movement pulse is not detected within one driving cycle of the line sensor, the scanner has not moved, so the image-processed line data stored in the buffer is discarded and the data of the next line is held. .

The PC card I / F unit 6 includes an information processing device 10
It performs an electrical interface to the server and performs interrupts and data access. The data transferred to the information processing device 10 is displayed on the display unit 11 of the information processing device 10 so that the image data being read can be confirmed.

In the example of FIG. 5, the information processing device 1
Although the data transfer is performed to 0, it is also possible to configure so that a plurality of line data are collectively transferred to the information processing apparatus 10 by increasing the buffer capacity in the read control unit 4. The above configuration is the basic configuration of the present embodiment. <First Embodiment> Three examples based on this basic configuration are shown in FIGS. 6 (1), 6 (2) and 6 (3). Here, the image reading unit 1 protruding outside the information processing apparatus 10
And the movement amount measuring unit 2 can be rotated with respect to the PC card unit 5. In FIG. 6A, the central axis of rotation is in the extension direction of the PC card unit 5. In FIG. 6 (2), the central axis of rotation is in the vertical direction of the extension direction of the PC card unit 5. In this case, the rotating mechanism constituting the rotating shaft is the PC card unit 5
And the image reading unit 1. In FIG. 6 (3), the center axis of rotation is in the vertical direction of the extension direction of the PC card unit 5 as in FIG. 6 (2).
The central axis of the PC card portion extension direction and the central axis of rotation are in a twisted positional relationship. That is, a rotation mechanism is provided at an end in the length direction of the image reading unit 1. With the above configuration, the display unit 11 of the information processing apparatus 10 can be always turned to the direction of the user regardless of the scanning direction, and the input image can be easily confirmed at the time of reading. <Second Embodiment> FIGS. 7 (1), 7 (2), 7
(3) shows a second embodiment of the present invention. These components are configured such that the image reading unit 1, the movement amount measuring unit 2, and the PC card unit 5 protruding outside the information processing apparatus 10 are separate bodies and have a connecting unit 21 for connecting each other.

The connecting portion 21 is a flexible cable 2
2 and a connector 23. In FIG. 7A, cable 2
2 is directly connected to the image reading unit 1 and is connected to the PC card unit 5 via a connector 23. FIG. 7 (2)
The cable 22 is directly connected to the PC card unit 5, and is connected to the image reading unit 1 via the connector 23. In FIG. 7C, the cable 22 is connected to the image reading unit 1 via a first connector 23, and is connected to the PC card unit 5 via a second connector 23.

As described above, since the connection is made using the connecting portion 21 such as the cable 22, there is no restriction on the scanning direction at a place distant from the apparatus. Further, since the housing housing the image reading unit 1 and the movement amount measuring unit 2 can be stored separately from the PC card unit 5 when not in use, there is an advantage that these can be easily stored. Note that the connection unit 2 that carries the image data is
As 1, the cableless connection may be performed using a wireless transmission unit or an optical transmission unit (not shown). <Third Embodiment> FIG. 8 shows a third embodiment of the present invention. In this drawing, the configuration is such that an analog image signal amplifying unit 25 that amplifies an analog image signal output from the image reading unit 1 that is a separate housing is provided in the housing that houses the image reading unit 1.

Since the read image signal is generally weak, if the distance between the image reading unit 1 and the image signal processing unit 3 is increased by connecting means such as a cable 22, the signal is read as being attenuated or affected by noise. Deteriorate the image signal. Then, by amplifying and transmitting the image signal in the housing, it is possible to read an image on the medium to be read, which is at a position distant from the information processing apparatus, in a free direction.

Therefore, in this example, it can be said that it is suitable when combined with the second embodiment. <Fourth Embodiment> FIGS. 9 (1), 9 (2), 9
(3) shows a fourth embodiment of the present invention. In this figure, P
Image reading unit 1 provided in a housing separate from C card unit 5
The driving condition setting unit 31 for setting the driving conditions is provided in the PC card unit 5. The line sensor included in the image reading unit 1 can sequentially read out the image signal based on the start signal indicating the head of the line and the clock for the effective pixels. By setting the effective reading pixels of the image reading unit 1 formed as a separate housing from the driving condition setting unit 31 and driving them,
Reading with freely changing the size of the sensor in another housing becomes possible. FIG. 9B is a diagram when the reading size of the line sensor is set for A4 width paper, and FIG.
FIG. 6 is a diagram when a reading size of a line sensor is set for a 6-width sheet. <Fifth Embodiment> FIG. 10 shows a fifth embodiment of the present invention. In the second embodiment, the configuration is such that the connection unit 21 can be housed inside the housing for the image reading unit 1 and the movement amount measurement unit 2 that protrudes outside the information processing apparatus 10. When the PC card unit 5 and the image reading unit 1 are connected to each other by the connection unit 21 and housed inside the housing, the reading in which the image reading unit 1 and the information processing apparatus 10 are integrated is not performed. It is possible to perform reading without restriction in the scanning direction at a place remote from the apparatus. <Sixth Embodiment> FIGS. 11A and 11B show a sixth embodiment of the present invention. This scanner uses a line sensor, and the order of the read data is limited to one direction. The example (A) of FIG. 11 shows the scanning of the read original and the scanner, and the result of the image read as a result. The line sensor of the scanner reads one line of data from the top in FIG. In the example of (A), the read image is as shown in the right figure and can be displayed as a normal image.

On the other hand, when the driving of the sensors is the same,
(B) When scanning is performed in the direction of the example, when the image is displayed as the result of the example (A), the read image becomes a mirror image. Therefore, a data order conversion means (not shown) for converting the data order of the read image data in accordance with the image reading direction given in advance by the reading control unit 4 is realized on the information processing apparatus side by a program. Then, the information processing apparatus issues an order conversion order to the reading control unit 4 of the card type scanner. The read controller 4 changes the read data of one line stored in the buffer to 1
A reverse process of the order corresponding to the Nth pixel is performed,
The data is transferred to the information processing apparatus 10 according to the read result of the example (B). This processing can prevent the mirror image from being read in the reading direction. <Seventh Embodiment> FIG. 12 shows a seventh embodiment of the present invention. When the card type scanner and the information processing apparatus 10 are integrated, the usability is improved by instructing the reading start / end from the command input of the information processing apparatus 10 or the operation button of the information processing apparatus from the operability.

That is, a read start / end instructing unit (not shown) for giving a read start / end instruction to the read control unit 4 is provided on the information processing apparatus side. The operation flow will be described with reference to the flowchart of FIG.

S1: The number of read lines is instructed from the information processing apparatus to the read control unit of the card type scanner. S2: A reading start instruction is given to the reading control unit by a command input of the information processing apparatus or an operation button of the apparatus.

S3: The reading control unit starts line input,
Transfer data to the information processing device. S4: If there is a command to interrupt the operation of the information processing apparatus or an operation button of the apparatus, the process ends even if the number of read lines has not been reached.

S5: When the specified number of read lines has been reached, the processing is terminated. According to the above flow, a reading operation instruction can be made from the information processing apparatus. <Eighth Embodiment> FIG. 13 shows an eighth embodiment of the present invention. This is an example in which a reading start / end instruction unit 41 for instructing the reading control unit 4 to start / end reading is provided on the image reading unit 1 and the moving amount measuring unit 2 which are separate from the PC card unit 5. is there.

When the image reading unit 1 is separated from the information processing apparatus by a cable 22 or the like as in the second embodiment, the image reading unit 1 is operated more than the operation on the information processing apparatus side as in the seventh embodiment. The usability is improved when the operation instruction can be made directly on the separate housing provided with the reading unit 1.

Therefore, as shown in FIG. 13, the operation of the scanner unit can be operated by providing an operation button on the housing and giving an operation instruction. The operation flow is the same as in FIG. 12, and the instruction from the device unit corresponds to the instruction from the instruction unit 41 provided on the housing. <Ninth Embodiment> FIG. 14 shows a ninth embodiment of the present invention. This is an example in which a reading auxiliary unit 51 that allows a sheet to be read to move on the front surface of the image reading unit 1 is detachably provided on the front surface of the image reading unit 1. Reading is performed by moving a sheet in front of the image reading unit 1 by the reading auxiliary unit 51. The reading auxiliary unit 51 has a pair of rollers disposed in a housing, and can be moved on the front surface of the image reading unit 1 by holding a sheet to be read between the rollers.

By manually moving the sheet between the reading auxiliary unit 51 and the image reading unit 1, it is possible to easily read a small-sized sheet which is difficult to read when integrated with the apparatus. .

The roller section is configured to rotate without a load. With the roller pressed against the scanner, insert the paper through the gap on the case. The roller section rotates with the movement of the inserted sheet. On the other hand, the roller unit is configured to contact the roller of the movement amount detection unit, and propagates the movement amount of the sheet to the movement amount detection unit. By inserting and moving the paper, it is assumed that the original is moved and scanned.
