It is arranged in a region between the feed roller tangent line L that is in contact with the feed roller 14 at a position spaced apart from the path T.

The circuit board 41 is a part that occupies a large area in the scanner 1, and causes an increase in the size of the apparatus. Since it is arranged in the region between the two, the size of the device in the direction intersecting with the document transport path T, more specifically in the direction orthogonal to the document transport path T can be suppressed.

In particular, when the apparatus body 2 is in the first posture shown in FIGS. 3 and 4, the document transport path T is closest to the vertical (document transport path T1). By arranging it in the region between T and the feed roller tangent line L, the size of the device in the Y-axis direction when not in use can be effectively suppressed, and the space occupied by the device in the Y-axis direction when not in use can be reduced. can be effectively suppressed.
It should be noted that the circuit board 41 is not limited to being completely within the area between the document transport path T and the feed roller tangent L when viewed in the width direction. They may intersect, or they may intersect only one of them.
Further, since the circuit board 41 is provided along the document transport path T when viewed in the width direction, the size of the apparatus in the direction intersecting the document transport path T can be suppressed more effectively.

Further, in the present embodiment, the second housing 25 (see FIG. 4) constituting the outer shell of the lower unit 3 is provided with an arch portion 25a along the rotation trajectory of the lower unit 3 at a position facing the support base 5, and the circuit The substrate 41 is arranged in a space 25d formed inside the arch portion 25a. As a result, the space inside the housing can be effectively used, and an increase in the size of the apparatus can be suppressed.

Next, the first cover 30 and the second cover 31 provided on the lower unit 3 will be described.
As shown in FIGS. 4, 6, and 8 to 12, a first cover 30 and a second cover 31 are provided on the rear surface of the lower unit 3 forming the apparatus body 2. As shown in FIGS. In each figure, reference numeral 30a indicates the outer surface of the first cover 30, and reference numeral 31a indicates the outer surface of the second cover 31. As shown in FIG.
Connection portions 33a and 33b (see FIGS. 8, 11 and 12) for connecting external cables 37 and 38 (see FIG. 10) are provided inside the first cover 30 and the second cover 31. . The connection portions 33 a and 33 b are provided on the circuit board 41 .
The external cable 37 is, for example, a cable for supplying power from an AC adapter (not shown), and the external cable 38 is, for example, a cable for communication with an external computer (not shown). A plug (not shown) is provided at the end of the external cable 37, and this plug is connected to the connection portion 33a. A connector (not shown) is provided at the end of the external cable 38, and this connector is connected to the connecting portion 33b. In the present embodiment, the plug insertion/extraction direction to the connection portion 33a and the connector insertion/extraction direction to the connection portion 33b are both directions along the V-axis direction.

The first cover 30 and the second cover 31 are provided to be openable and closable. FIG. 12 shows a state in which both the first cover 30 and the second cover 31 are open.
When the first cover 30 and the second cover 31 are opened, access ports 32a and 32b for accessing the connecting portions 33a and 33b are exposed as shown in FIG. Reference numeral 32a denotes an access port to the connection portion 33a, and reference numeral 32b denotes an access port to the connection portion 33b.

The access openings 32a and 32b are provided in the frame member 29, and the access opening 32a is surrounded by a projecting portion 29a projecting in the -V direction, which is the direction opposite to the area where the circuit board 41 is arranged. Similarly, the access port 32a is surrounded by a projecting portion 29b projecting in the -V direction, which is the direction opposite to the area where the circuit board 41 is arranged.

As shown in FIGS. 11 and 12, the first cover 30 is opened and closed by rotating about a rotating shaft 30a, and the second cover 31 is opened and closed by rotating about a rotating shaft 31a. In this embodiment, the rotating shaft 30a and the rotating shaft 31a are parallel, and both are parallel to the X-axis direction.
The first cover 30 is urged clockwise in FIGS. 11 and 12 by the coil spring 35, that is, in the closing direction, and is closed as shown in FIG. 11 unless the user keeps the open state.

A protrusion 30c is provided on the first cover 30 at a position facing the free end of the second cover 31. The protrusion 30c enters a recess 31g formed in the free end of the second cover 31, thereby The closed state of the second cover 31 is maintained.
Therefore, when the first cover 30 is opened, the protrusion 30c is pulled out of the recess 31g, and the second cover 31 is rotatable and can be opened. In the present embodiment, the second cover 31 is not applied with an external force by a spring or the like, and when it is opened to some extent, it can transition to the fully open state shown in FIG. 12 by its own weight.

The second cover 31 is positioned vertically below the first cover 30 irrespective of the posture of the apparatus main body 2, and the second cover 31 has cables through it as shown in FIGS. Portions 31c and 31d are formed. The cable threading portion 31c is a cable threading portion corresponding to the access port 32a, and the cable threading portion 31d is a cable threading portion corresponding to the access port 32b.
The cable passing portions 31c and 31d are composed of slits extending in the V-axis direction, and as shown in FIG. formed. Similarly, the inlet portion 31f of the cable passing portion 31d is also formed at a position slightly displaced from the position where the slit extends in the X-axis direction. As a result, when the external cables 37 and 38 are respectively passed through the cable passing portions 31c and 31d, the respective external cables are held in the respective cable passing portions.

As described above, in this embodiment, as shown in FIGS. 4, 8, and 10, the cable passing portion for covering the connection portions 33a and 33b for connecting the external cables 37 and 38 and passing the external cables 37 and 38 is provided. Since the second cover 31 provided with 31c and 31d is positioned below the first cover 30, if a foreign object falls from above the connecting portions 33a and 33b, it will be connected via the cable passing portions 31c and 31d. A structure that makes it difficult for foreign matter to enter the portions 33a and 33b can be provided.

Further, since the first cover 30 is provided so as to be openable and closable, opening it facilitates the work of connecting the external cables 37 and 38 to the connecting portions 33a and 33b, respectively. In addition, since the first cover 30 is pressed in the closing direction by the coil spring 35 (see FIGS. 11 and 12), which is an example of the pressing means, it is possible to prevent the first cover 30 from being left unclosed. entry of foreign matter can be more reliably suppressed.
Although the first cover 30 is openable and closable in this embodiment, it may be fixed.

Further, in the present embodiment, the second cover 31 is held in the closed state by being caught by the projection 30c that is a part of the first cover 30 in the closed state (see FIG. 11). It is possible to reduce the cost of the device as compared with the case of separately providing a dedicated configuration for holding the state.

The circuit board 41 provided with the connection portions 33a and 33b and the frame member 29 forming the periphery of the connection portions 33a and 33b are provided. The liquid that has entered from one of the peripheral edges is guided away from the circuit board 41 .
More specifically, as shown in FIG. 11, the frame member 29 has a shape that separates an arrangement area 42 for the circuit board 41 from an inner area 43 of the first cover 30 and the second cover 31. For example, when a liquid enters from the peripheral edge of at least one of the cover 30 and the second cover 31 and falls on the upper surface 29c of the frame member 29 (see also FIG. 8), the liquid will flow through the frame member as indicated by the arrow a in FIG. 29 leads away from the circuit board 41 . As a result, adhesion of liquid to the circuit board 41 can be suppressed.

As shown in FIG. 8, the periphery of the access openings 32a and 32b formed in the frame member 29 are protruding portions protruding in opposite directions to the arrangement area 42 (see FIG. 11) of the circuit board 41 (see FIG. 11). 29a and 29b, even if liquid falls on the upper surface 29c of the frame member 29, the liquid is prevented from adhering to the connecting portions 33a and 33b.

Further, the device main body 2 can be switched between a first posture, which is a posture when not in use, and a second posture, which is a posture when in use and in which the projected area with respect to the mounting surface G is larger than that in the first posture. 11, the connecting portions 33a and 33b are oriented vertically higher than in the second posture (see FIG. 12), and the first cover 30 is positioned vertically above the connecting portions 33a and 33b. For this reason, in the first posture of the apparatus main body 2, when a foreign object or the like drops from vertically above the connection portions 33a and 33b, the foreign matter is likely to enter the connection portions. Since the first cover 30, which is a cover in which the cable passage portions 31c and 31d are not formed, is positioned above 33b, entry of foreign matter into the connection portions 33a and 33b is effectively suppressed.

Further, when the device body 2 is in the second posture as shown in FIG. 6, and when the device body 2 is in the third posture as shown in FIG. Therefore, it is possible to suitably suppress entry of foreign matter into the cable passing portions 31c and 31d.
