Moreover, in each figure, the same reference number is attached | subjected to the same member or the same element, and description is abbreviate | omitted about the overlapping content hereafter.

  FIG. 1 is a perspective view for explaining the structure of the line sensor device 1 according to the embodiment. In order to facilitate understanding of the structure, the X axis, the Y axis, and the Z axis that are orthogonal to each other are shown in the drawing (the same applies to other drawings). The XY plane corresponds to a plane parallel to the detection surface of the line sensor device 1 and will be described in detail later, but the line sensor device 1 has a structure extending in the Y direction. The Z direction corresponds to a direction perpendicular to the detection surface.

  In the present specification, the expression indicating the direction is used to indicate a relative positional relationship. For example, expressions such as “right” and “right side” correspond to the + X direction, and expressions such as “left” and “left side” correspond to the −X direction. For example, expressions such as “upper” and “upper” correspond to the + Z direction, and expressions such as “lower” and “lower” correspond to the −Z direction.

  In the present embodiment, the line sensor device 1 includes a rod lens array 11, a pair of inner support members 12L and 12R, a line sensor substrate 13, a pair of outer support members 14L and 14R, a light source unit 15, mounting substrates 16 and 17, A plate 18 and a plate material 19 are provided. The rod lens array 11 extends in the Y direction, and includes a plurality of rod lenses arranged in the Y direction (the Y direction in the figure corresponds to the arrangement direction of the rod lenses). Each rod lens collects incident light from above, and the Z direction in the figure corresponds to the optical axis direction.

  The inner support members 12L and 12R are two elongated members that both extend in the Y direction. These are respectively arranged on the left side and the right side of the rod lens array 11, that is, arranged so as to be separated from each other and opposed to each other in the X direction, and sandwich the rod lens array 11 from both sides. An adhesive (not shown) may be provided between the rod lens array 11 and the inner support member 12L and / or between the rod lens array 11 and the inner support member 12R. That is, the sandwiching of the rod lens array 11 by the inner support members 12L and 12R means that the rod lens array 11 is fixed by being positioned on a straight line between the inner support members 12L and 12R. Use or non-use. Alternatively / additionally, the surface of the inner support member 12L (or 12R) that sandwiches the rod lens array 11 may be subjected to anti-slip surface processing. As another embodiment, the inner support members 12L and 12R may be integrally formed. For example, the inner support members 12L and 12R are integrally connected by a connecting member extending in the X direction at a part (for example, both end portions) in the Y direction. May be. In this embodiment, the inner support members 12L and 12R are made of aluminum. However, as another embodiment, the inner support members 12L and 12R may be made of other metals or may be made of an organic material such as a resin. .

  The line sensor substrate 13 is mounted with a line sensor composed of a CCD / CMOS image sensor, and a plurality of photoelectric conversion elements (here, photodiodes) are arranged in the Y direction on the substrate. The line sensor substrate 13 is supported by the inner support members 12L and 12R and is fixed on the optical path of the light collected by the rod lens array 11. In the present embodiment, the line sensor substrate 13 is fixed to the lower ends of the inner support members 12L and 12R. With such a configuration, the light collected by the rod lens array 11 is received and detected by the line sensor substrate 13.

  Each of the outer support members 14L and 14R constitutes a part of the housing in the line sensor device 1, and specifically forms a side surface portion extending in the Y direction. Each member thru | or each element demonstrated by this specification are directly or indirectly supported and fixed with respect to the outer side support members 14L and 14R. In this respect, the outer support members 14L and 14R may be expressed as a fixing member or the like. In the present embodiment, in the XZ plane, the outer support members 14L and 14R both have shapes extending in the Z direction. The outer support members 14L and 14R support and fix the inner support members 12L and 12R between them (fix them on the side portions of the inner support members 12L and 12R). In the present embodiment, the outer support members 14L and 14R are members independent of each other, and are connected to each other by a plate material 19 described later at an end portion in the Y direction. As another embodiment, the outer support members 14L and 14R may be integrally formed, for example, by connecting members extending in the X direction at least at a part in the Y direction (for example, both end portions, the central portion, etc.). They may be connected together. The outer support members 14L and 14R are made of aluminum in the present embodiment, like the inner support members 12L and 12R. However, as another embodiment, the outer support members 14L and 14R may be made of other metals, such as resin. You may be comprised with an organic material.

  The outer support member 14L includes an upper end portion 141L (one end portion) extending in a direction away from the inner support member 12L on the upper side thereof. Similarly, the outer side support member 14R includes an upper side end portion 141R extending in a direction away from the inner side support member 12R on the upper side thereof.

  The light source unit 15 extends in the Y direction, and irradiates light on a reading object or a subject (not shown) that can be disposed above the rod lens array 11. The light source unit 15 includes a plurality of light sources 152 arranged in the Y direction on a substrate 151. In the present embodiment, the light source unit 15 is an LED array in which LEDs (light emitting diodes) are arranged as light sources. The light source unit 15 is fixed to inclined surfaces formed on the upper side end portions 141L and 141R (in the drawing, the light source unit 15 fixed to the upper side end portion 141L is shown. The light source unit 15 is similarly fixed to the unit 141R.) With such a configuration, the light source unit 15 irradiates the reading object with light.

  The mounting boards 16 and 17 both extend in the Y direction, and are printed circuit boards on which elements such as semiconductor ICs and connectors can be mounted. In the present embodiment, elements for realizing functions other than light detection (functions of the line sensor substrate 13), that is, signal reading based on the detection results of the line sensor substrate 13 are performed on the mounting substrates 16 and 17. An element is implemented. The concept of this element generates the power required to realize signal reading, in addition to the processing unit that processes the signal to be read, the conversion unit that converts the signal into data of a predetermined standard, and the connector for signal communication. A power supply circuit (power supply IC), a power supply connector, and the like are also included.

  Although details will be described later, the mounting boards 16 and 17 are both fixed to the outer support members 14L and 14R, respectively. In the present embodiment, the mounting board 16 is located below the outer support members 14L and 14R (the other end). The mounting substrate 17 is further fixed below the mounting substrate 17. In addition, although the two mounting substrates 16 and 17 are illustrated here, the number of mounting substrates is not restricted to this example, One may be sufficient and three or more may be sufficient.

  The top plate 18 extends in the Y direction and is a light-transmitting plate material that forms the detection surface of the line sensor device 1. The top plate 18 is fixed to each of the upper end portion 141L of the outer support member 14L and the upper end portion 141R of the outer support member 14R. An adhesive or the like is used for this fixing. The upper ends of the upper side end portions 141L and 141R form a flat surface, and the flat surface acts as a contact surface with the top plate 18, so that the fixing of the top plate 18 is stabilized. The top plate 18 is a glass plate in this embodiment, but other light transmissive materials may be used.

  The plate material 19 constitutes a part of the housing in the line sensor device 1 and specifically seals the inside of the device 1 together with the outer support members 14L and 14R at the end in the Y direction. More specifically, the plate member 19 together with the outer support members 14L and 14R prevents intrusion of foreign matters (dust etc.) into the apparatus 1 such as a space above the line sensor substrate 13, for example. Here, the plate member 19 is fixed to each of the outer support members 14L and 14R with screws (not shown), an adhesive, or the like, and is also fixed to the support members 12L and 12R incidentally.

  With the configuration described above, the line sensor device 1 can read an image recorded on a recording medium (for example, paper) as an example of a reading object. Specifically, the light source unit 15 irradiates the recording medium with light while scanning the recording medium relative to the top plate 18 of the line sensor device 1. Then, the reflected light from the recording medium is collected by the rod lens array 11, and the collected light is detected by the line sensor substrate 13. Thereafter, the line sensor device 1 reads out a signal based on the detection result on the line sensor substrate 13 by the mounting substrates 16 and 17, thereby acquiring image data indicating an image on the recording medium. The concept of the image includes, for example, a blank (substantially the same area as the background color of the paper) in addition to visually recognizable information such as characters, symbols, patterns, figures, pictures, and photographs. .

  The line sensor device 1 is not limited to the configuration exemplified above, and other configurations may be adopted as necessary. For example, as another embodiment, an area sensor substrate in which a plurality of photoelectric conversion elements are arranged in a matrix or a staggered pattern may be used instead of the line sensor substrate 13 (in this respect, the concept of the line sensor). Can also include area sensors.) Alternatively, other photodetecting elements or light receiving elements such as a PIN sensor and a MIS sensor may be used as the photoelectric conversion element instead of the photodiode. Further, for example, in the present embodiment, the light source unit 15 is an LED array, but as another embodiment, other light emitting elements may be used as the light source 152 instead of the LEDs. Alternatively, a light guide that extends in the Y direction and is configured to irradiate an upper reading object may be used as the light source unit 15.

  FIG. 2 shows a side view of the line sensor device 1 from the right side. On the outer support member 14R (and 14L), the top plate 18 and the plate material 19 shown in the figure are fixed by screws, adhesives, etc., and each element inside the apparatus 1 described with reference to FIG. Or indirectly fixed.

  3 is a cross-sectional view for explaining a cross-sectional structure (cross-sectional structure in the XZ plane) passing through the cutting line AA of FIG. The inner support members 12L and 12R are configured symmetrically and face each other so as to sandwich the rod lens array 11 as described above. In this embodiment, each rod lens has a so-called clad core structure, that is, the central portion (the portion illustrated in white, the core) forms a light propagation path, and the peripheral portion (in dots). The illustrated portion (cladding) has a structure configured so that light does not leak from the central portion. Thereby, the irregular reflection of light that can occur between the inner support members 12L and 12R of the rod lens array 11 is suppressed (the loss of light is reduced), and the light condensing performance by the rod lens array 11 is improved. it can.

  The outer support members 14L and 14R are configured symmetrically, and as described above, the inner support members 12L and 12R are fixed therebetween. The two light source units 15 arranged on the inclined surfaces of the upper end portions 141L and 141R are illustrated as the light source units 15L and 15R, respectively. In the present embodiment, the light source units 15L and 15R are located above the rod lens array 11. This prevents the light sources 15L and 15R from being shaded when irradiating the reading object (recording medium) with light.

  In the present embodiment, the outer support member 14L and the inner support member 12L are fastened using screws SC1 with the spacers SP1 disposed therebetween, and the screws SC1 are provided so as to penetrate the spacers SP1. . Although details will be described later, with such a configuration, the outer support member 14L and the inner support member 12L are fixed apart by a predetermined distance, and a space or gap is formed between them. Note that a bolt may be used in place of the screw SC1 for fastening the outer support member 14L and the inner support member 12L. Further, as the spacer SP1, a member having a thickness sufficient to secure a desired distance between the outer support member 14L and the inner support member 12L may be used, and a spacer provided with a screw hole is used. Alternatively, a washer may be used. The same applies to the outer support member 14R and the support member 12R.

  The line sensor substrate 13 includes a substrate 131 and a plurality of photoelectric conversion elements 132 forming a line sensor. The substrate 131 is fixed to the lower ends of the inner support members 12L and 12R using screws SC2. Here, the lower ends of the inner support members 12 </ b> L and 12 </ b> R form a flat surface, and the flat surface acts as a contact surface with the upper surface of the substrate 131, so that the fixing of the substrate 131 is stabilized.

  The mounting substrate 16 is fixed to the recessed portion on the inside of the lower end portions of the outer support members 14L and 14R by using screws SC3. The mounting substrate 17 is fixed below the mounting substrate 16 to the outer portions of the lower end portions of the outer support members 14L and 14R using screws SC4. In order to realize such a structure, the width in the X direction of the mounting substrate 17 is set larger than the width in the X direction of the mounting substrate 16.

  A processing unit 161 for performing signal processing based on the detection result of the line sensor substrate 13 and a transmitter for performing transfer or communication of the signal processed data are mounted on the top surface of the mounting substrate 16. The processing unit 161 is an ASIC (application-specific integrated circuit) in this embodiment, but as another embodiment, other integrated circuits such as a PLD (programmable logic device) may be used, and signal processing may be performed. Other feasible configurations may be employed. The transmitter can transfer the data by a predetermined transfer method, and in this embodiment, the transmitter is configured to be able to transfer data compliant with the camera link (Camera Link (registered trademark)) standard.

  On the lower surface of the mounting board 16, a connector CN1 for external connection is mounted. The connector CN1 is disposed so as to pass through an opening provided in the mounting board 17, so that the mounting board 16 can be directly connected to an external device. In the present embodiment, the connector CN1 is a connector for receiving external power, and this external power is converted into desired power by AC / DC conversion or the like in a power supply circuit (not shown) mounted on the mounting board 16, for example. Is done. Thereafter, the converted electric power is supplied to each element such as the line sensor substrate 13 and the processing unit 161.

  The connector CN2 is mounted on the lower surface of the mounting substrate 16. In the present embodiment, the connector CN2 is a connector for outputting the power for the light source unit 15 generated based on the external power. In the present embodiment, the connector CN2 functions as a power supply unit for supplying power to the light source unit 15 or a part thereof, and the wiring WR1 is connected thereto. In the present embodiment, the connector CN2 is a connector that can output the power generated by the power supply circuit as the power for the light source unit 15, but as another embodiment, the external power is directly used as the power for the light source unit 15. In the case of a configuration to be used, the power supply circuit may not be used. Therefore, the concept of the power supply unit includes a connector for receiving external power (connector CN1 in the example in the figure), a power supply circuit that converts the external power into desired power, and / or the converted power. Is included (in the example shown, connector CN2).

  Although details will be described later, the wiring WR1 is a flexible cable having a predetermined thickness (for example, a diameter), and in this embodiment, from the connector CN2 side to the light source unit 15L side, the outer support member 14L and the inner side It extends so that it may pass between the support members 12L. Although not shown here, the light source unit 15R is similarly provided with a wiring unit for supplying power from the connector CN2 to the light source unit 15R.

  On the lower surface of the mounting substrate 17, a connector CN3 for external connection is mounted. The upper surface of the mounting substrate 17 and the lower surface of the mounting substrate 16 are connected by a connector CN4. Further, the upper surface of the mounting substrate 16 and the lower surface of the substrate 131 are connected by the connector CN5. In the present embodiment, the line sensor substrate 13 and the mounting substrates 16 and 17 are electrically connected by such a configuration. As another embodiment, a flexible wiring such as a flexible printed wiring board (FPC) or a chip on film (COF) may be used instead of the connectors CN4 and / or CN5.

  With the above structure, for example, the detection result on the line sensor board 13 is output to the connector CN5, subjected to signal processing by the processing unit 161, and then transmitted to the external device as image data via the connector CN4 and the connector CN3. Is output.

  In this structure, the line sensor substrate 13 is fixed to the inner support members 12L and 12R, while the mounting substrate 16 on which the processing unit 161 is mounted is fixed to the outer support members 14L and 14R. The inner support member 12L and the outer support member 14L are separated by a predetermined distance by the spacer SP1, and similarly, the inner support member 12R and the outer support member 14R are separated by a predetermined distance by the spacer SP1. Therefore, when acquiring image data, the mounting board 16 can generate a considerable amount of heat due to the signal processing of the processing unit 161. However, according to this structure, this heat hardly propagates to the line sensor board 13. . The heat that can be generated by driving the light source unit 15 is also difficult to propagate to the line sensor substrate 13 for the same reason. Therefore, according to this embodiment, it is advantageous to suppress the fluctuation of the characteristics of the line sensor substrate 13 due to these heats and stabilize the characteristics.

  In the wiring WR1 connected to the light source unit 15L, the outer support member 14L and the inner support member 12L are appropriately directed downward so as not to interfere with the irradiation light to the reading object or the reflected light from the subject. It is required to extend through to the connector CN2. Therefore, a guide portion for guiding the wiring WR1 downward may be provided at the upper end portion 141L to which the light source portion 15L is fixed.

  FIG. 4A shows a top view of a corner portion of the line sensor device 1 as a first example. In the drawing, the upper end portion 141L of the outer support member 14L, the inner support member 12L, the spacer SP1 that forms the space G1 therebetween, the light source portion 15L fixed to the upper end portion 141L, the wiring WR1, and A plate material 19 is shown. The light source unit 15L includes a connector 153 that receives power for driving the plurality of light sources 152 arranged in the Y direction at the end thereof. The wiring WR1 is connected to the connector 153. As another embodiment, when the light source unit 15 does not include the connector 153, the wiring WR1 may be directly connected to the terminal of each light source 152.

  Here, on the surface of the outer support member 14L, in this example, the inclined surface (upper surface) of the upper end portion 141L and the inner wall of the outer support member 14L, a groove TR1 is provided as an example of the guide portion. The wiring WR1 is disposed so as to pass through the trench TR1. Accordingly, since the wiring WR1 is appropriately fixed and guided downward, it is possible to prevent a situation in which the wiring WR1 is positioned above the light source 152 and obstructs the irradiation light and the reflected light.

  Here, the structure has been described focusing on the corner portion corresponding to the light source portion 15L, but the other corner portions corresponding to the light source portion 15R may be similarly configured. For example, this structure may be configured to have symmetry in plan view in the Z direction, and may be line symmetric (the axis of symmetry is parallel to the Y direction) or point symmetric.

  FIG. 4B shows a top view of the corner portion of the line sensor device 1 as a second example, as in the first example (see FIG. 4A). In the present example, as an example of the guide portion, the upper end portion 141L is provided with an opening OP1 that communicates with the inner wall of the outer support member 14L below the upper end portion 141L. The wiring WR1 is arranged to pass through the opening OP1. Accordingly, since the wiring WR1 is appropriately fixed and guided downward, it is possible to prevent a situation in which the wiring WR1 is positioned above the light source 152 and obstructs the irradiation light and the reflected light.

  FIG. 4C shows a top view of the corner portion of the line sensor device 1 as a third example, similarly to the first to second examples (see FIGS. 4A to 4B). In this example, as an example of the guide part, a notch is provided in the end part in the Y direction of the upper end part 141L, and a space G2 is formed between the plate member 19 and the outer support member 14L. As a result, the wiring WR1 can be positioned so that the wiring WR1 appropriately passes through the space G2, and the occurrence of a situation in which the wiring WR1 is positioned above the light source 152 and obstructs the irradiation light or the reflected light can be prevented. it can.

  According to the present embodiment, the wiring WR1 that connects the light source unit 15L and the connector CN2 can be provided at a relatively short distance by passing between the outer support member 14L and the inner support member 12L. In order to reduce the length of the wiring WR1, the wiring WR1 passes between the outer support member 14L and the inner support member 12L in the X direction, in other words, a path that overlaps both the outer support member 14L and the inner support member 12L in the X direction. Pass through. For example, in the YZ plane, the wiring WR1 can be extended substantially in a straight line from the connector 153 side of the light source unit 15L, that is, from one end in the Y direction toward the connector CN2 that can be disposed inside the one end. . In the present embodiment, a spacer SC1 is disposed between the outer support member 14L and the inner support member 12L, and the outer support member 14L and the inner support member 12L are fastened by screws SC1 that penetrate the spacer SC1. The wiring WR1 passes through the space G1 (see FIG. 4A, etc.) formed by the spacer SC1 between the outer support member 14L and the inner support member 12L. Therefore, according to the present embodiment, it is possible to shorten the wiring WR1 with a relatively simple configuration. For example, it is possible to reduce costs and prevent handling errors during manufacturing and maintenance.

  In the present embodiment, the screw SC1 is used to fix the outer support member 14L (or 14R) and the inner support member 12L (or 12R), but a space or gap is formed between them for the wiring WR1 to pass therethrough. What is necessary is just to fix those aspects, and is not restricted to the above-mentioned example. For example, as another embodiment, the spacer SP1 through which the screw SC1 passes may be integrally formed with one of the outer support member 14L and the inner support member 12L, that is, one of the outer support member 14L and the inner support member 12L. May have a protruding portion with respect to the other. As another embodiment, a groove for allowing the wiring WR1 to pass between them may be provided in one or both of the outer support member 14L and the inner support member 12L without using the spacer SP1. Further, as a modification of the above-described second example (see FIG. 4B), the wiring WR1 passing through the opening OP1 is also connected to the outer support member 14L and the opening OP1 by providing the opening OP1 below the inner support member 12L. The shape passes between the inner support members 12L.

  Referring again to FIG. 2, a space surrounded by the rod lens array 11, the inner support members 12 </ b> L and 12 </ b> R, and the line sensor substrate 13 is formed in the line sensor device 1. In order to prevent irregular reflection of light in this space, the surfaces of the inner support members 12L and 12R made of aluminum in this embodiment may be colored black by, for example, alumite treatment. Similarly, for each of the light source units 15L and 15R, the upper surface of the substrate 151 may be black-finished so as to prevent reflection of light, so that the space between the top plate 18 and the rod lens array 11 can be reduced. It is also possible to prevent irregular reflection of light in space. In addition, although black was illustrated here as an example of the color for preventing reflection of light, this color should just be selected so that a visible light absorptance may be 70% or more (preferably 90% or more). .

  Moreover, the outer side support member 14 equivalent to the housing | casing of the line sensor apparatus 1 is comprised with aluminum similarly to the inner side support members 12L and 12R in this embodiment. The surface of the outer support member 14 may be colored white by, for example, anodizing for improving the design.

  The inner support members 12L and 12R are required to have a predetermined accuracy in order to directly fix the rod lens array 11 and the line sensor substrate 13, and as described above, are created by cutting in this embodiment. On the other hand, as for the outer support members 14L and 14R, it is only necessary to suppress the influence of distortion or the like on the rod lens array 11 and the line sensor substrate 13 that are indirectly fixed via the inner support members 12L and 12R. Can be created.

  FIG. 5 shows a configuration of a system SY of a printer (may also be called a recording device, a printing device, an image forming device, etc.) as an example of a recording system to which the line sensor device 1 is applied. For the printer, a known recording method such as an inkjet method or an electrophotographic method can be adopted.

  The system SY includes the line sensor device 1 as a reading device, and also includes a recording head 2, a processor 3, and a plurality of transport rollers 4. The recording head 2 is driven by an electrical signal based on printing data, and records an image on the recording medium P by ejecting a liquid such as ink onto the recording medium P. The processor 3 outputs an electrical signal based on the printing data to the recording head 2 to drive the recording head 2. The transport roller 4 transports the recording medium P based on the drive signal from the processor 3. In the present embodiment, the transport roller 4 transports the recording medium P on which an image has been recorded by the recording head 2 toward the line sensor device 1 in the direction indicated by the one-dot chain line in the drawing.

  The line sensor device 1 is detachably accommodated in the printer, and reads an image on the recording medium P recorded by the recording head 2. The processor 3 receives the reading result by the line sensor device 1 and can correct the driving force (for example, the liquid ejection amount) of the recording head 2 based on the reading result, and the recording needs to be performed again. It is also possible to notify the user that this is the case.

  The present invention is not limited to the embodiments exemplified above, and modifications can be made without departing from the spirit of the present invention. In addition, it is needless to say that each term described in this specification is merely used for the purpose of describing the present invention, and the present invention is not limited to the strict meaning of the term.
