Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an image reading apparatus having a reading section for reading an image on a document and a recording section for printing an image on a sheet material.
The present invention relates to a technology that can be used for an image reading and recording apparatus such as a scanner printer.

[0002]

2. Description of the Related Art Facsimile has almost completely spread to general companies, and in recent years has spread widely to general households. A
Companies that need to read a large number of fixed-size sheet-like originals such as four sizes at a time require a facsimile having a large-capacity and high-speed automatic document feeder (ADF). Was big. However, since it is not necessary to read a large number of documents at a time in ordinary households, the ADF does not need to have such a large capacity. Rather, there is a strong demand for a facsimile capable of reading various originals as needed, such as large-format originals such as newspapers, irregular-type originals, and originals such as books and magazines in which the ADF cannot be used.

In order to meet these demands, a reading unit is configured to be detachable from a facsimile apparatus main body.
A so-called hand scanner type facsimile is widely used. According to this method, an apparatus has been put to practical use in which the above various originals that cannot pass through the ADF are manually sub-scanned by a hand scanner detached from the main body, and the image of the original is read by a built-in image sensor.

In recent years, there has been an increasing demand for reading image information at a location far from the installation location of the apparatus main body, so that a hand scanner can be carried to read an image at a remote location. For this purpose, cordless hand scanners, which do not have a data communication code required to connect the apparatus main body and the hand scanner, have become widely used.

[0005] With the development of the cordless system, the configuration of an electric circuit in a facsimile apparatus is greatly different from that of the conventional one. In other words, since the hand scanner unit and the apparatus main body have always been connected by a cable, a control unit for controlling the reading unit / recording unit / communication unit and the like and a gate array for performing image processing of the read image are required. It should have been provided on the main unit side, but with the cordless system, the hand scanner side also has a control unit for controlling the reading unit consisting of the image sensor, a gate array, and a memory unit for storing image data. While a power supply unit for driving them is provided, a control unit for controlling a recording unit and a communication unit is provided on the apparatus main body side. As described above, the facsimile reading unit has been made cordless as a hand scanner as described above, and the reading unit / recording unit has also been colorized at the same time, so that color copying as well as color copying is becoming possible in ordinary households.

[0006] On the other hand, devices that are rapidly spreading in recent years include digital cameras and digital devices for photographing and reproducing digital images typified by digital video. These devices take captured portrait and landscape images into a personal computer, display them on the screen, and output them to a printer.With the spread of these devices, users who do not own a personal computer do not need to use a personal computer. There is a growing demand for easily outputting digital images.

Therefore, image data can be directly taken in without using a personal computer and output to a recording sheet by using an easily removable storage medium represented by a memory card such as a "compact flash" or "smart media". Various output devices have also been proposed.

In such a background, with the facsimile colorization, the facsimile can be utilized as the above digital image output device, and the above-described cordless hand scanner is used for the facsimile device. It is conceivable to attach the storage medium (hereinafter, also referred to as a memory card) such as the above-mentioned “compact flash” or “smart media” to the hand scanner in a detachable manner.

The provision of the slot for making the memory card detachable from the hand scanner as described above connects the read image processing unit and the read control unit to the memory card from the viewpoint of preventing deterioration of the image signal and protection from noise. This is because the shorter the signal line, the better, and it is reasonable to provide a slot on the hand scanner side.

[0010]

However, as described above, if an attempt is made to provide a slot for a memory card in a hand scanner, an operation for inserting and removing a memory card from a conventional cordless hand scanner is further added. Operation becomes complicated. Further, from the layout point of view, a large space for the memory card and a large number of signal lines are required, which results in an increase in the substrate area and an increase in the size of the hand scanner body.

In general, if a memory card is inserted or removed while power is being supplied (during access to the card), the memory may be destroyed. For this reason, when the slot of the memory card is provided in the hand scanner, a cover is provided in the slot portion of the memory card, and when the user inserts and removes the memory card, the cover is opened and closed to detect the opening and closing of the cover. The memory card is protected by restricting the operation of the read control unit such as not supplying power or accessing the memory card when the memory card is opened.

However, in such a configuration in which the opening / closing cover is provided, it is necessary to prevent the operator from accidentally touching the cover and opening the cover during manual scanning with the hand scanner. Therefore, it is necessary to provide a complicated configuration for preventing the lock of the cover from being easily opened or a configuration that can be opened only by a special tool, which causes a complication and an increase in cost.

Accordingly, the present invention has been made in view of the above-mentioned problems, and is provided in a main body of a hand scanner which is detachable from the apparatus main body, detached from the apparatus main body, and reads an original by manual scanning. It is an object of the present invention to provide an image reading apparatus having an optimal layout that can maintain excellent operability with a simple configuration when providing a slot for inserting and removing a memory card as a second storage unit and further providing an opening / closing cover. .

Only the lowermost sheet is separated and transported to the document reading section 5. The document separated by the ADF unit 4 in this manner is
The sheet is guided to the nip portion between the feed roller 51 and the feed roller 52, and is nipped and conveyed. When the leading end of the document is detected by a sensor (not shown) provided in the vicinity of the feeding roller 51, the reading motor rotates a predetermined number of steps and then stops, and stops the document at a predetermined position before the CIS 61. Then, C
The IS 61 reads the shading data of the white reference plate 54 and corrects the output level of the read signal. And
After the reading motor is again rotated to convey the original document by a predetermined number of steps to reach the reading line of the CIS 61, the lower surface of the original document is sequentially read line by line. The document that has been read is guided to the nip portion between the discharge rollers 53 and the rollers 62, is nipped and conveyed, and is discharged out of the apparatus through the opening 16 provided on the front surface of the apparatus. When a plurality of originals are set, the reading motor is rotated until the sensor 57 detects that there is no original, the ADF unit 4 separates and transports the originals one by one, and the CIS 61 sequentially reads the image data. repeat.

Next, the overall configuration of the apparatus will be described. 3 and 4 are a perspective view and a sectional view, respectively, showing a state when the operation panel unit 7 is opened. 5 and 6 are a perspective view and a cross-sectional view, respectively, showing how the hand scanner is taken out.

In both figures, the CIS 61 and the roller 62 are supported by a housing 63 and are configured as a hand scanner unit 6 so as to be integrally detachable from the apparatus main body 1. Case 6
Reference numeral 3 functions as a guide member for guiding the lower surface of the document, and also functions as a guide member for guiding the upper surface of the recording paper. Guide members 58 and 59 are provided to guide the upper and lower surfaces of the original, respectively. The above-mentioned ADF unit 4, feed roller 52, paper discharge roller 53, white reference plate 54, and sensors 56 and 57 It is supported by a member 58. The guide member 59 is also supported by the guide member 58, and forms the above-described opening. The guide member 58 is fixed to the operation panel section 7, and the operation panel section 7
Is configured to be vertically rotatable integrally with the guide member 58 about the fulcrum 71. A release lever 73 for releasing a lock (not shown) that the operation panel unit 7 holds and fixes at a predetermined position of the apparatus main body 1 is provided. The operation panel unit 7 is unlocked by pushing up the release lever 73. Then, it is configured to be rotatable around the fulcrum 71.

By pushing up the operation panel unit 7 in this manner, the document conveying path is exposed, and the document jam can be cleared, and the hand scanner 6 can be taken out of the machine. At this time, the replacement opening 17 of the ink cartridge 31 is exposed, and the opening 1 is opened.
7, the ink cartridge can be accessed, and the ink cartridge 31 can be replaced, for example, when the ink runs out. Further, when the hand scanner 6 is detached from the apparatus main body 1, the upper portion of the opening 13 forming the recording paper discharge port is opened, so that the jam of the recording paper is easily performed. As a result, the recording paper is discharged in the front direction of the apparatus, and problems such as difficulty in removing the recording paper are eliminated.

Further, a holder 8 for receiving a hand scanner provided to be swingable with respect to a fulcrum (not shown) of the apparatus main body.
Is biased upward by a spring, and when the hand scanner 6 is taken out, the holder 8 jumps upward, so that the hand scanner 6 can be easily received.
A pair of guide rails 81 provided opposite to each other are provided inside the left and right side walls of the holder 8. The guide rails 81 are fitted to each other to guide the hand scanner 6 until the hand scanner 6 fits in a predetermined position of the holder 8.

An interface connector 82 is provided on the back wall of the holder 8. When the hand scanner 6 is mounted at a predetermined position in the holder 8, an interface connector 82 provided on the hand scanner 6 is provided. 6
5, the connector 82 is connected, and the hand scanner 6 and the apparatus main body 1 are electrically connected.

The spring force of the spring pushing up the holder 8 is set to be smaller than the pushing force of the hand scanner 6 due to its own weight.
When the hand scanner 6 is completely mounted on the holder 8, the hand scanner 6 is lowered by its own weight together with the holder 8 until the hand scanner 6 hits an abutting position (not shown) provided on the apparatus main body 1. The installation is completed.

On the other hand, when removing the hand scanner 6 from the apparatus main body 1, the lower hand scanner 6 is grasped by its own weight and pulled out in parallel with the guide rail 81 (in the direction of the arrow X in the figure), and the guide rail 81 and the groove 64 are drawn. It is configured to be pulled out until the fitting is released.

When the hand scanner 6 is removed, the apparatus main body 1 enters a mode in which only functions other than the reading function (telephone, reception, recording...) Can be operated, while the hand scanner 6 is in a state capable of manual scanning. .

Next, the configuration of the hand scanner 6 will be described. FIG. 7 is a perspective view showing a state in which the hand scanner 6 alone is viewed from the front with the document reading surface facing down (hereinafter, the vertical relationship of the hand scanner 6 alone is based on this state). FIG. 8 is a rear perspective view for explaining insertion and removal of a memory card.

In both figures, on the upper surface of the hand scanner 6, there are provided a reading operation key 66, a switching key 67 for designating image quality and a document size at the time of manual scanning, and an LED 68 for indicating the operating state of the hand scanner 6 by lighting or blinking. ing. A cover 9 configured to be openable and closable by the hand scanner 6.
The cover 91 has a slot 9 in which a memory card can be attached and detached. The slot 9 of the memory card is disposed on the opposite side near the connector 65. A hinge 91b is provided at one end of the cover 91, and the cover 91 is configured to be openable and closable about the hinge 91b. At the time of opening, the knob 91a provided on the cover 91 is pinched and lifted upward, thereby exposing the slot 9 of the memory card.

In this embodiment, a compact flash is used as a memory card. This cover 91
Is provided with a projection 91c.
The open / closed state of the cover 91 is detected by a detection member 94 that engages with the cover 91. When the cover 91 is opened, the protrusion 91c separates from the detection member 94, detects that the cover 91 is opened, stops the power supply to the memory card slot 9, and restricts the operation of the control unit of the hand scanner 6. In addition, destruction of the memory due to insertion and removal of the memory card while power is supplied to the memory card is prevented. Since the cover 91 is pivotally supported by the hinge portion 91b with respect to the hand scanner 6 and cannot be easily removed simply by moving the cover 91 in the rotating direction, the cover 91 may be lost or forgotten to operate due to forgetting to attach the cover 91. No problems occur.

The eject button 92 and the memory card 9
The eject button 92 is engaged with a link mechanism (not shown), and when the eject button 92 is pushed in, the link mechanism pushes out the memory card mounted in the slot. Has become.
The eject button 92 is provided at the end of the hand scanner 6. When the eject button 92 is pressed by a finger, the eject button 92 secures a space where the finger can be easily moved, and simultaneously accesses the memory card and controls the eject button 92. Care is taken to ensure that access does not cross with fingers.

A grip 63a is provided at the center of the hand scanner housing 63, and the operator grips the grip 63a to perform manual scanning. The grip portion 63a has a width dimension L, and is set to a width of about 100 mm as a dimension that can be reliably gripped by an operator. The cover 91, the memory card slot 9 and the connector 65 are on the right side of the grip 63a and have the width L
The operation key 66 and the switching key 6
7 and an LED 68.

With the above configuration, when the operator grips the hand scanner 6, carelessly touches the keys (the operation keys 66 and the switching keys 67) and the cover 91 to cause a scanning error,
Care is taken to prevent the electronic component from being broken by touching the connector 65 to short-circuit the terminals.

FIG. 9 shows a hand scanner 6 according to this embodiment.
FIG. 2 is a block diagram illustrating a configuration of a device main body 1.

In this figure, a hand scanner section 6 is a reading section (B) comprising a CIS 61 for optically reading the original surface.
3), an encoder (B4) for measuring the movement amount of the hand scanner 6 from the rotation amount of the roller 62, an image processing unit (B2) for digitizing the output voltage from the reading unit (B3), and storing the digitized image data Image memory (B7), an interface (B9) including a connector 65 electrically connected to the apparatus main body 1, an operation key 66, a switching key 67, and an LED
68, a memory card (B8) that can be inserted into and removed from the hand scanner 6, a control unit (B1) that controls the operation of the hand scanner 6 by receiving inputs from the operating unit (B6) or the interface (B9). ) And a battery (B5) for supplying power to the hand scanner 6.

On the other hand, the main body side is an interface (B9)
(B) consisting of a connector 82 connected to the
15), an operation unit (B12) including the operation panel 7, a modem (B13) connected to a telephone line and communicating with another communication terminal such as a facsimile, and a memory unit (B1) for storing image data.
4) a recording unit (B1) for outputting image data to recording paper
1) and a control unit (B10) for controlling the operation of the apparatus main body 1.

Next, FIG. 10 is a perspective view showing a state in which the original surface is manually scanned using the hand scanner 6.
In general, facsimile machines are often arranged so that the handset is held with the left hand, and this is because many people have the dominant hand on the right hand, so that complicated operations such as key input and document setting can be easily performed. This is the result of considerations for Japan. Therefore, when the handset is held in the left hand, operations such as manual scanning of a document using the hand scanner 6 can be easily performed by using the right hand without having to switch between left and right. In order to stabilize the straightness of the hand scanner 6 when the hand scanner 6 is manually scanned, the hand scanner 6 may be used.
It is good to operate it by holding the approximate center. This is because the sliding resistance acting between the hand scanner 6 and the surface of the document or the surface on which the document is placed works equally to the left and right with respect to the operation force by hand, and the hand scanner 6 is unlikely to skew.

As described above, when the hand scanner 6 is gripped by the right hand, the operation key 66, the switching key 67, the LED
The operation unit such as 68 is easy to operate if it is arranged on the left side of the gripping unit. Also, if the memory card slot cover 91 and the connector 65 are arranged on the right side, the probability of touching by mistake can be reduced. It is possible to improve the operability of the hand scanner 6 and stabilize the operation by natural operation without forcing.

FIG. 11 is a perspective view illustrating the structure of the substrate inside the hand scanner 6. In the figure, the interface connector 65, the memory card slot 9, the control section (B1) and the image processing section (B2) have a large amount of signals to be communicated, and the number of poles of the signal lines inevitably increases to several tens. However, these signals are susceptible to noise and may lead to deterioration of image quality. In order to avoid the influence of such noise, it is desirable to make the path as short as possible. Therefore, in this embodiment, the memory card slot 9, the interface connector 65, the control unit (B1), and the image processing unit (B2) are configured on the same substrate 95, and the memory card slot 9 and the interface connector 65 are located on the right side of the substrate. It is designed to combine the improvement of the operability and the prevention of the deterioration of the image quality.

On the other hand, the board 96 on which the operation section is integrated is constituted by a single-sided board in which relatively inexpensive switches are arranged on the board 95 with a reduced number of mounted components, thereby achieving a cost reduction effect.

FIG. 12 is a view showing a state in which the cover 91 is opened, and FIGS. 13 and 14 are views for explaining a state before and after the hand scanner 6 is mounted on the holder 8.

In these figures, as described above, the cover 91 is configured to rotate about the hinge 91b, and when the cover 91 is opened, a space for pushing the eject button 92 and for inserting and removing the memory card 93 is provided. Can be secured. Therefore, the opening angle θ of the cover 91 is, for example, 5
It is set to 5 °.

When the hand scanner 6 is mounted on the holder 8, the guide rail 81 and the groove portion 64 are fitted and pushed in the direction of the arrow Y until the holder is completely mounted. Is the front side in the mounting direction, and the open movable side is the rear side. A cover restricting member 83 is provided at a position where the cover restricting member 83 comes into contact with the cover 91 when the hand scanner 6 is mounted. If the operator forgets to close the cover 91, the cover restricting member 83 contacts the cover 91. ,
The cover 91 is rotated in the closing direction in accordance with the pushing operation of the hand scanner 6, so that when the hand scanner 6 is completely mounted on the holder 8, the cover 91 is also completely closed.

Further, while the hand scanner 6 is held by the holder 8, the cover regulating member 83 is always in contact with the cover 91 so that the cover 91 is not opened. In the present embodiment, the opening angle θ of the cover 91 is set to 55 °, and according to experiments, if the opening angle of the cover 91 is an acute angle of 90 ° or less, the cover restricting member with respect to the mounting direction of the hand scanner 6. It has been confirmed that the ease with which the cover 83 closes the cover 91 and the ease of operations such as insertion and removal of a memory card can be achieved.

The cover restricting member 83 is provided on the holder 8 near the guide rail 81. B4
In the case of a hand scanner that can read a document with a width, the length is close to 300 mm, and the holder 8 is inevitably also a horizontally long part. Management becomes difficult.

As a result, when the positional dimensions of the guide rail 81 and the cover restricting member 83 are out of order, the cover 91 cannot be completely closed, and the cover 91 and the cover restricting member 83 interfere with each other and the hand scanner 6 cannot be mounted. appear. Therefore, the guide rail 81 and the cover restricting member 83 are arranged in the vicinity and at the end of the component which is hardly affected by the warp, thereby avoiding the above-mentioned problem.

In the above embodiment, the ink jet system for recording an image by ejecting ink on the recording paper is employed for the recording unit.
The same effect can be obtained by applying the thermal transfer method or the LBP method.

The same effect can be obtained by applying the present invention to an image reading / recording apparatus having a reading section and a recording section such as a copying machine or a scanner printer other than the facsimile apparatus.
