The upper document guide 105 and the operation unit A can be opened using the shaft 105a in FIG. 1 as a rotation axis. Note that the upper document guide is opened in advance when the hand scanner 201 is attached or detached.

In FIGS. 2 and 3, the hand scanner holder 301 is rotatably pivoted to the transport roller 120 by passing the shaft of the transport roller 120 through holes 301a provided at opposing positions of both side plates 301b. Has been stopped. The hole 301 of the hand scanner holder 301
a is loosely fitted with a certain play to the transport roller 120 serving as a shaft. In the present invention, the diameter of the hole 301a of the hand scanner holder is 0.8 mm larger than the shaft diameter of the transport roller. The torsion coil spring 302 is supported by the transport roller 120, and has one end fixed to the side plate and the other end fixed to the side surface of the hand scanner holder.

A projection 304 is formed on a surface 303a of the cover 303 surrounding the hand scanner holder 301, which faces both side walls of the hand scanner holder 301. The protrusion 304 is formed such that a surface 304a at the tip thereof has a predetermined gap with the side wall 301b of the hand scanner holder, thereby forming the protrusion 304 in the width direction of the hand scanner 201 (arrow 3).
05) is roughly regulated. Also, a stopper rib 30 formed on the side wall of the hand scanner holder is provided.
1c and the side surface 304b of the projection regulate the hand scanner holder 301 to rotate within a predetermined range.

In the above configuration, the torsion coil spring 30
2 is designed so that a spring force acts to rotate the hand scanner holder 301 in the direction of the arrow 306.
The spring constant of the torsion coil spring 302 is such that when the hand scanner 201 is detached, the hand scanner holder 301 is lifted up and abuts against a stopper (not shown) to be held at a detachable position (FIG. 2). In the mounted state, the hand scanner holder 30
1 is the weight of the hand scanner 201 and the weight of the spring 30
Hand scanner 201
Is held at the reading position of the sheet document.

Rails 307 are formed inside the side walls on both sides of the hand scanner holder 301, and grooves 308 are formed on both side walls of the hand scanner. When the hand scanner 201 is inserted into the hand scanner holder 301 along the rail, first, the rail 3 is used in both the vertical direction and the width direction.
07 and the groove 308, there is no play at least after contact between the connector 206 and a connector 311 described later, and the shape of the rail and the groove is adjusted so that the relative positions of the connector 206 and the connector 311 are surely matched. Is determined. The direction of the rail 307 is determined by the connectors 311 and 206.
And the height is substantially the same as the outer peripheral surface of the transport roller 120 and the glass surface of the color contact sensor 202 disposed on the hand scanner 201 when the hand scanner 201 is mounted. The height has been adjusted.

A guide surface 309 is formed integrally with the cover 303 at the front of the main body. Guide surface 30
Reference numeral 9 functions as a document conveyance guide when reading a sheet document, and serves as a guide for engaging the groove 308 of the hand scanner 201 with the rail 307 of the hand scanner holder 301 held at the detachable position when the hand scanner is attached. When the hand scanner 201 is removed, the hand scanner holder 301 is held at a detachable position (the state shown in FIG. 2) by the torsion coil spring 302.
Low holding power. For this reason, when aligning the groove 308 with the rail 307, the holder 301 escapes downward, making it difficult to set the hand scanner. Therefore, the guide surface 309
Is provided. The position of the guide surface 309 is adjusted such that the groove 307 and the rail 308 are engaged simply by placing the hand scanner 201 on the guide surface 309 and sliding the hand scanner 201 in the direction of mounting the hand scanner holder 301 as it is (FIG. 4, FIG. 5).

The lower surface 201 of the hand scanner 201
When a completely exceeds the guide surface (FIG. 7), a connector to be described later is connected, and the hand scanner 201 is designed to be completely housed in the hand scanner holder 301. It cannot be lowered. This prevents the user from mounting errors. In addition, the guide surface 309 is arranged in front of the hand scanner and shared with the document transport guide, thereby reducing the size of the apparatus in the width direction.

A large notch 301d is formed in the center of the bottom of the hand scanner holder. this is,
This is because when the operator grips the hand scanner 201 and inserts or removes it from the hand scanner holder 301, the hand may hit if the bottom surface 301f of the hand scanner holder is over the entire surface. In addition, when the user leaves, it is hidden behind the hand scanner and cannot be seen at all.

As described above, the recording paper of the present apparatus is discharged from a lower portion hidden by the hand scanner. Therefore, when a short recording paper is ejected, or when the recording paper has a paper jam or the like and its leading end slightly comes out of the pair of ejection rollers 108, the operation unit is opened and the hand scanner is removed. The processing is performed after making the recording paper discharge port 129 easy to access. At this time, a notch 301d is also provided so that the bottom surface 301f of the hand scanner holder does not get in the way. Further, the notch 301d increases the space 128 (see FIG. 1) below the hand scanner 201 accommodated in the hand scanner holder 301, and improves the stacking performance of the recording paper and the discharge performance when the recording paper is curled. it can.

The hand scanner holder 301 has
An interface board 312 and a connector 311 that engages with the connector 206 are attached. When the hand scanner 201 is housed in the hand scanner holder 301, the control board 1 in the main body is connected via a cable (not shown) attached to the interface board 312.
12 is connected.

The interface board 312 is attached from the hand scanner side to the surface 301e of the hand scanner holder 301 which is the boundary with the recording unit. Also,
There is a hole in the surface 301e where the interface board 312 is attached, through which a cable passes. In this state, only the hole is exposed to the recording unit side. Further, the interface substrate 312 is formed on a single-sided substrate, and the surface 31 facing the hand scanner 102 is formed.
2a is attached to the hand scanner holder 301 so that the solder surface and the surface 312b facing the recording section C become the mounting surface. For this reason, the conductive ink mist flying from the ink jet recording unit is supplied to the substrate 31 from the hole.
Even if it adheres to 2, the pattern is short-circuited and does not emit smoke or fire because it is a mounting surface and has no pattern.

<Mounting Method of Hand Scanner> Next, a mounting method of the hand scanner and positioning of the hand scanner will be described.

FIGS. 4 to 8 show the steps of mounting the hand scanner in a step-by-step manner, and show only those parts necessary for making the mechanism easy to understand. The hand scanner is mounted and positioned on the main body in three steps.

First, the operator operates the upper document guide 105.
Open until it is secured with the stopper. Then, the hand scanner holder 301 stops in a state where it has been raised to the detachable position as described above (FIG. 4). Next, the hand scanner 201 is slid toward the inner side of the holder with the hand scanner 201 placed on the guide surface 309, and then slid along the rail 307 to be attached to the hand scanner holder 301 (FIGS. 5 to 7). As described above, the hand scanner 201 uses the rail 307 and the groove 308 to hold the hand scanner holder 3.

Is securely connected.

In this state, the hand scanner 201 is integrated with the hand scanner holder 301 and
It freely moves in the rotational direction 401 shown in FIG. Next, the hand scanner holder 30
1. The hand scanner 201 integrated with the transfer roller 1
Rotate about 20 and lower it to the reading position (FIG. 8). Here, the position of the hand scanner 201 in the downward direction is determined by abutting the surface 201a on the rib 402 formed on the main body frame, and the position in the front-rear direction is determined by sandwiching the hand scanner 201 between the surface 403 and the rib 404.
The surface 403 is formed obliquely so as not to interfere with the rotation of the hand scanner. In other words, hand scanner 2
When 01 is lowered, the hand scanner 201 comes into contact with the surface 403 and the position is inevitably determined. The hand scanner holder 301 is rotatable in the upward direction. However, when the upper document guide 105 is closed, the hand scanner holder 301 is urged by the paper discharge roller 116 to completely determine the position.

With the above configuration, the hand scanner 2
01 is in contact with the main body frame when it is stored, that is, in the state of reading a sheet document, and its relative position is directly determined with respect to the main body frame. For this reason, the positional deviation between the paper feed roller 120 and the document end detection sensor 127 attached to the main body frame 111 can be minimized. As a result, image quality such as a reading position and skew is improved. If the connector 206 and the connector 311 are not connected, the hand scanner 201 is moved to the hand scanner holder 301.
Therefore, the connector 206 and the connector 311 are securely connected at the time of reading a sheet document.

Further, since the hand scanner holder 301 and the main body are axially fixed with a certain play, the position of the hand scanner 201 in the housed state is set at the position of the transport roller which is the rotation axis of the hand scanner holder 301. You will not be bound. The position of the hand scanner 201 is the same as that of the hand scanner 201 and the surfaces 403 and 4 in the front-back direction.
The horizontal direction is determined by the hand scanner 201, the side wall of the holder 301, and the projection 304 of the main body. The vertical direction is determined by the rail 307 of the hand scanner, the groove 308 of the holder, the surface 402 of the main body, and the upper document guide. 105. That is, the hand scanner 201 is not positioned twice. For this reason, since no extra external force acts on the connector or the like, troubles such as defective contacts are eliminated.

<Method of Removing Hand Scanner> Next, the removal of the hand scanner 201 will be described. First,
Open the upper document guide 105 until it is fixed by the stopper. In this state, the operator holds the hand scanner 201,
Lift the hand scanner holder 301 until it catches on the stopper. When the hand scanner holder 301 is hooked on the stopper, the hand scanner holder 301 is in a state where the hand scanner can be attached and detached, as shown in FIG. Then, the hand scanner 201 is pulled out while being lifted.

As described above, in the facsimile apparatus of the present embodiment, when the hand scanner is attached / detached, the upper original guide at the top can be opened, and the access to the hand scanner becomes easy.

Further, by providing a notch on the bottom surface of the holder for accommodating the hand scanner, the body of the hand scanner can be easily held, the handle for taking out can be eliminated, and the hand scanner can be detached and used. Operability has been improved.

Further, by arranging the hand scanner holder and the recording portion discharge port so that the cutout portion of the hand scanner holder is located above the recording paper discharge port, the upper document guide is opened and the hand scanner is removed.
