Conventionally, as an optical information reading device that optically reads an information code such as a bar code or a two-dimensional code, it is a mounting type reading device that reads by holding the information code over a reading port while being mounted on a mounting table. Alternatively, there is a portable reading device that reads by pointing the reading port toward the information code while gripping the grip portion or the like. For example, in a reading device for a POS cash register installed in a counter or the like in a store, it is assumed that the information code is read with the reading device mounted or the information code is read with the reading device held. Therefore, it may be required that one reading device has both a function as a mounted type and a function as a portable type.

As a technique related to a reading device having both a function as a stationary type and a function as a portable type, for example, an optical reading device disclosed in Patent Document 1 below is known. This optical reader is provided with a head portion in which the main body of the reader has a light source and a light receiving means and a handle that can be grasped by the user, and can be used as a stationary reader by setting the main body of the reader on a stand. It is configured. A first reading window and a second reading window are provided on the front surface of the head portion, and the first scanning pattern through the first reading window is suitable for stationary reading (stationary reading). The second scanning pattern through the second reading window is set to be suitable for handheld reading (portable reading).

[First Embodiment]
Hereinafter, the first embodiment embodying the optical information reading device according to the present invention will be described with reference to the drawings.
The optical information reading device 10 shown in FIGS. 1 to 6 is configured as a code reader that optically reads one or two or more information codes (one-dimensional code, two-dimensional code, etc.), and is configured in different directions. It is a reading device for making the located information code easier to read. The optical information reading device 10 according to the present embodiment is placed on a cash register counter in a store, for example, and not only reads a barcode or the like attached to a purchased product held over a reading port, but also an operator can read it. It is configured to read a bar code or the like that is gripped and pointed at the reading port.

The outer shell of the optical information reading device 10 is composed of a housing 11 made of a synthetic resin such as ABS resin. The housing 11 is configured to include a reading unit 20, a gripping unit 30, and a mounting unit 40 in order to serve as both a mounting type and a portable type.

The reading unit 20 is configured to accommodate electronic components such as light receiving sensors 63a and 63b, which will be described later, inside the reading unit 20, and is provided with a reading port 23a on the front surface 21 and reads on the rear surface 22 opposite to the front surface 21. It is formed so that the mouth 23b is provided. The reading port 23a is formed so that the light receiving range Sa of the light receiving sensor 63a via the reading port 23a is larger than the light receiving range Sb of the light receiving sensor 63b via the reading port 23b.

The front surface 21 is provided with an extending portion 24 extending forward so as to face the information code from the upper side except for a portion of the periphery of the reading port 23a on the grip portion 30 side. The extension portion 24 is formed so that the extension end portion 25 covers the outer edge of the light receiving range Sa by the light receiving sensor 63a via the reading port 23a. More specifically, as shown in FIG. 3, in the extension portion 24, the grip portion side (lower side) of the extension end portion 25 is the farthest from the grip portion 30 of the outer edge of the light receiving range Sa of the light receiving sensor 63a. It is formed along the vertical edge (upper edge). The front surface 21 may correspond to an example of the "first surface", and the reading port 23a may correspond to an example of the "first reading port". Further, the rear surface 22 may correspond to an example of the "second surface", and the reading port 23b may correspond to an example of the "second reading port".

The gripping portion 30 is formed in a substantially columnar shape so as to be easily gripped, and is between the reading portion 20 and the mounting portion 40 so as to integrally connect the lower surface of the reading portion 20 and the upper surface of the mounting portion 40. Have been placed. The grip portion 30 is formed so as to be inclined with respect to the mounting portion 40 so that the reading portion 20 is displaced toward the back side (right side in FIG. 4) in order to improve gripability from an obliquely upward direction or the like (FIG. 4). See 4th grade). A trigger button 54a, which will be described later, is arranged near the reading unit 20 on the back surface side of the grip unit 30.

The mounting portion 40 is arranged so as to be integrally connected to the lower end of the grip portion 30 at the center of the upper surface thereof. In order to ensure stability when the optical information reading device 10 is mounted on a mounting surface such as a cash register counter, the mounting portion 40 has a range in which the bottom portion 41 vertically projects the reading unit 20 at the time of mounting. It is formed to be wider than. On the back side of the mounting portion 40, a fixing portion (not shown) for fixing a communication cable (not shown) drawn out to the outside is provided.

Here, the role of the extension unit 24 of the reading unit 20 and the like will be described below.
The extending portion 24 is formed so that the grip portion side of the extending end portion 25 is along the upper edge (the edge of the outer edge farthest from the grip portion) of the light receiving range of the light receiving sensor 63a. As a result, the information code is reliably positioned within the light receiving range Sa by the light receiving sensor 63a simply by aligning the gripping portion side (lower side) of the extending end portion 25 with the upper edge of the information code. The reading port 23a can be more easily oriented with respect to the reference.

In particular, since the extending portion 24 is formed so as to extend around the reading port 23a except for the portion on the grip portion side, the optical information reading device 10 can be miniaturized.
That is, if the extension portion 101 is formed so as to surround the entire periphery of the reading port as in the optical information reading device 100 shown in FIG. 10, the extension portion 101 becomes an obstacle and a short grip portion. Since it becomes difficult to grip the grip portion 102, it is necessary to provide the grip portion 102 longer in the longitudinal direction. Therefore, the height of the optical information reading device 100 from the mounting surface becomes high, and the optical information reading device 100 becomes large.

On the other hand, in the optical information reading device 10 according to the present embodiment, the extending portion 24 is formed so as to extend around the reading port 23a except for the portion on the grip portion side. As shown in 9, the gripping portion 30 can be easily gripped without the extending portion 24 getting in the way. As a result, since the grip portion is difficult to grip due to the portion of the extension portion on the grip portion side, it is not necessary to lengthen the grip portion in the longitudinal direction, so that the grip portion 30 can be miniaturized, that is, optically. The size of the information reading device 10 can be reduced.

Next, the electrical configuration of the optical information reading device 10 will be described with reference to the drawings.
The optical information reading device 10 includes a control unit 51 that controls the entire device. The control unit 51 is mainly composed of a microcomputer, has a CPU, a system bus, an input / output interface, and the like, and constitutes an information processing device together with a memory 52. Further, as shown in FIG. 7, the control unit 51 is connected to a light emitting unit 53, an operation unit 54, a vibrator 55, a speaker 56, an external interface 57, an optical unit 60, and the like.

The operation unit 54 is provided with a trigger button 54a or the like and is configured to give an operation signal corresponding to the operation to the control unit 51, and the control unit 51 receives the operation signal and responds to the content of the operation signal. Perform the operation. The light emitting unit 53 is, for example, an LED, and is configured to light up and blink according to control by the control unit 51. The vibrator 55 is composed of a known vibrator mounted on a mobile device, and is configured to generate vibration in response to control by the control unit 51. The speaker 56 is composed of known speakers, and is configured to emit (pronounce) a predetermined sound such as a preset sound or an alarm sound according to the control by the control unit 51. The external interface 57 is configured as an interface for performing data communication with an external device or the like via a communication cable or the like, and is configured to perform communication processing in cooperation with the control unit 51.

The optical unit 60 functions in cooperation with the control unit 51 to optically read optical information such as an information code, and as shown in FIG. 8, the illumination light source 61a arranged on the reading port 23a side. An imaging lens 62a and a light receiving sensor 63a, an illumination light source 61b arranged on the reading port 23b side, an imaging lens 62b, and a light receiving sensor 63b are provided.

The illumination light source 61a functions as an illumination light source capable of emitting the illumination light Lfa. For example, the illumination light source 61a is composed of a red LED and a lens provided on the exit side of the LED, and the illumination light is emitted through the reading port 23a. It is arranged to irradiate Lfa. The light receiving sensor 63a is, for example, an area sensor in which light receiving elements are arranged two-dimensionally, and the reflected light Lra from an information code or the like incident on the housing 11 via the reading port 23a is transmitted through the imaging lens 62a or the like. It is mounted on a printed wiring board (not shown) so that it can receive light. The imaging lens 62a arranged between the reading port 23a and the light receiving sensor 63a is configured to form an image of the information code C on the light receiving sensor 63a. Note that FIG. 8 illustrates a state in which the illumination light Lfa is applied to the reading target R to which the information code C is attached on the reading port 23a side.

Further, the illumination light source 61b functions as an illumination light source capable of emitting the illumination light Lfb, and is composed of a red LED and a lens or the like provided on the exit side of the LED like the illumination light source 61a. It is arranged so as to irradiate the illumination light Lfb via 23b. The light receiving sensor 63b is, for example, a line sensor in which light receiving elements are arranged one-dimensionally, and the reflected light Lrb from an information code or the like incident on the housing 11 via the reading port 23b is transmitted through the imaging lens 62b or the like. It is mounted on a printed wiring board so that it can receive light. The imaging lens 62b arranged between the reading port 23b and the light receiving sensor 63b is configured to form an image of the information code C on the light receiving sensor 63b. Note that FIG. 8 illustrates a state in which the illumination light Lfb is applied to the reading target R to which the information code C is attached on the reading port 23b side. Further, the optical unit 60 is provided with an amplifier circuit that amplifies the signal from the light receiving sensor 63a and the light receiving sensor 63b, an AD conversion circuit that converts the amplified signal into a digital signal, and the like. Is omitted. The light receiving sensor 63a and the light receiving sensor 63b can correspond to an example of the "light receiving means".

In the optical information reading device 10 configured in this way, reading using the reading port 23a and reading using the reading port 23b are possible. In particular, when the trigger button 54a is not operated, reading using the reading port 23a is possible, and when the trigger button 54a is operated, reading using the reading port 23b is possible. That is, the trigger button 54a functions as an operation unit that is operated when switching between a state in which light is received through the reading port 23a and a state in which light is received via the reading port 23b.

For example, when reading is performed using the reading port 23a because the trigger button 54a is not operated, first, the illumination light Lfa is emitted from the illumination light source 61a commanded by the control unit 51, and the illumination light Lfa is emitted. It is irradiated through the reading port 23a. Then, when the illumination light Lfa is reflected by the information code C, the reflected light Lra is taken into the housing 11 through the reading port 23a and received by the light receiving sensor 63a through the imaging lens 62a. The light receiving sensor 63a outputs a light receiving signal corresponding to the image of the information code C. The control unit 51 performs decoding processing for decoding the information code C in response to the light receiving signal output from the light receiving sensor 63a.

Therefore, for example, in the mounted type reading state in which the optical information reading device 10 is placed on the cash register counter to read the information code C attached to the product, the upper edge of the information code C is extended end portion 25. The reflected light Lra from the information code C is received by the light receiving sensor 63a by holding it over the reading port 23a along the grip portion side of the above. As a result, the information code C can be smoothly read even when the optical information reading device 10 is used as a mounted type.

Further, when reading is performed using the reading port 23b because the trigger button 54a is operated, first, the illumination light Lfb is emitted from the illumination light source 61b commanded by the control unit 51, and the illumination light Lfb is emitted. It is irradiated through the reading port 23b. Then, when the illumination light Lfb is reflected by the information code C, the reflected light Lrb is taken into the housing 11 through the reading port 23b, and is received by the light receiving sensor 63b through the imaging lens 62b. The light receiving sensor 63b outputs a light receiving signal corresponding to the image of the information code C. The control unit 51 performs decoding processing for decoding the information code C according to the light receiving signal output from the light receiving sensor 63b.

Therefore, for example, in a portable reading state in which the grip portion 30 of the optical information reading device 10 is gripped and the information code C attached to a large product that is difficult to lift on the cashier counter is read, the grip portion 30 is gripped. By operating the trigger button 54a, reading using the reading port 23b becomes possible. At this time, since the reading port 23b with the grip portion 30 gripped is facing forward with respect to the operator, the reading port 23b is directed toward the information code in the gripped state as it is gripping the grip portion 30. It will be easier. Then, by pointing the reading port 23b toward the information code C, the reflected light Lrb from the information code C is received by the light receiving sensor 63b. As a result, the information code C can be smoothly read even when the optical information reading device 10 is used as a portable type.

As described above, in the optical information reading device 10 according to the present embodiment, a reading port 23a is formed as a first reading port on the front surface 21 of the reading unit 20 of the housing 11, which is opposite to the front surface 21. A reading port 23b is formed as a second reading port on the rear surface 22 of the housing 11 on the side. Then, the reflected light from the information code (optical information) is received by the light receiving sensor 63a via the reading port 23a, or is received by the light receiving sensor 63b via the reading port 23b.

As a result, when the grip portion 30 is gripped and used as a portable type from the state where the reading port 23a is used as a mounted type so as to face the operator as described above, the grip portion 30 is gripped. The reading port 23b of the above is directed forward with respect to the operator, and the reading port 23b can be easily directed to the information code in the gripped state as it is gripping the grip portion 30. Therefore, it is possible to reduce the troublesome operation for gripping even when both the stationary type and the portable type are used.

Further, the grip portion 30 is arranged between the reading portion 20 having the reading port 23a and the reading port 23b and the mounting portion 40, and is formed so as to be inclined with respect to the mounting portion 40. Normally, the grip portion 30 in the mounted state is located diagonally downward when viewed from the operator, so that when gripping the grip portion 30 from an obliquely upward direction, the grip portion is perpendicular to the mounting portion. As compared with the case where the grip portion 30 is formed, the grip portion 30 can be easily gripped, and the troublesome operation for gripping can be further reduced.

Further, the grip portion 30 is provided with a trigger button 54a that is operated when switching between a state in which light is received via the reading port 23a and a state in which light is received via the reading port 23b. As a result, the trigger button 54a can be easily operated when the grip portion 30 is gripped, so that the light receiving state for mounting can be smoothly switched to the light receiving state for carrying in the gripped state.

In particular, the extending portion 24 is formed so as to extend around the reading port 23a except for the portion on the grip portion side. As a result, since the grip portion is difficult to grip due to the portion of the extension portion on the grip portion side, it is not necessary to lengthen the grip portion in the longitudinal direction. Therefore, the reading port 23a is provided for the desired information code. The grip portion 30 can be miniaturized, that is, the optical information reading device 10 can be miniaturized while making it easy to turn.

Further, the extending portion 24 is formed so that the grip portion side of the extending end portion 25 is along the outer edge (upper edge) of the outer edge of the light receiving range Sa of the light receiving sensor 63a, which is farthest from the grip portion. As a result, the information code C is reliably positioned within the light receiving range Sa by the light receiving sensor 63a simply by aligning the gripping portion side of the extending end portion 25 with the upper edge of the information code C. It is possible to make it easier to point the reading port 23a with respect to the desired information code.

The extension portion 24 is not limited to being formed so that the grip portion side of the extension end portion 25 is formed along the upper edge of the light receiving range Sa of the light receiving sensor 63a, and the extension portion 24 is located on the grip portion side of the periphery of the reading port 23a. It may be formed so as to extend except for the site. For example, as in the extension portion 24a illustrated in FIGS. 11 and 12, the extension end portion 25a is the upper edge and the left and right side edges of the light receiving range Sa except for the grip portion side portion around the reading port 23a. It may be formed so as to surround at least a part of the above. Even in this case, since the grip portion is difficult to grip due to the portion of the extension portion on the grip portion side, it is not necessary to lengthen the grip portion in the longitudinal direction, so that the desired information code can be read. The grip portion 30 can be miniaturized, that is, the optical information reading device 10 can be miniaturized while making it easy to direct the mouth 23a.

Further, when the reading workability is more important than the miniaturization of the grip portion 30, the extending portion 24 reads at least a part around the reading port 23a, for example, the extending portion 101 of FIG. It may be formed so as to extend from all around the mouth 23a and the extending end portion 25 covers the outer edge of the light receiving range Sa by the light receiving sensor 63a via the reading port 23a. As a result, by positioning the information code so as to be surrounded by the extension end portion 25 of the extension portion 24, the information code is reliably positioned within the light receiving range Sa by the light receiving sensor 63a via the reading port 23a. Therefore, it is possible to easily point the reading port 23a at the desired information code.

FIG. 13 is a graph showing the relationship between the opening size X of the reading port and the reading work time. The reading work time indicates the work time until the reading is completed when the work of reading the information code is performed using the reading port having the opening size X. Further, reference numerals F1, F2, and F3 in FIG. 13 indicate cases where the shutter speeds are 1/250, 1/500, and 1/1000, respectively, and reference numeral Fb indicates a case where the grip portion is gripped and read. There is.

As can be seen from FIG. 13, the reading work time becomes shorter as the opening size X is increased up to a predetermined opening size Xa (for example, 70 × 70 mm), while the reading work time changes when the opening size Xa is exceeded. It becomes smaller. As described above, there is an opening size that can shorten the reading work time even if it is small depending on the reading work environment and the like. By adopting such an opening size, the optical information reading device 10 can be miniaturized and the reading work can be performed. It is possible to improve both sex.

Therefore, when the extending portion 24 is formed so as to extend so as to surround the reading port 23a, the opening size formed by being surrounded by the extending end portion 25 is the reading working environment as described above. By setting the size so that the reading work time can be shortened even if the size is small, the workability of the reading work using the reading port 23a can be improved.

Further, the reading port 23a is formed so that the light receiving range Sa of the light receiving sensor 63a via the reading port 23a is larger than the light receiving range Sb of the light receiving sensor 63b via the reading port 23b. As a result, the near information code is read through the reading port 23a, and the distant information code is read through the reading port 23b. This not only distinguishes between the time of mounting and the time of carrying, but also the reading port according to the reading environment. Since the 23a and the reading port 23b can be used properly, the convenience of the reading work can be improved.

[Second Embodiment]
Next, the optical information reading device according to the second embodiment of the present invention will be described with reference to FIG.
The second embodiment is mainly different from the first embodiment in that it automatically switches between a state in which light is received through the reading port 23a and a state in which light is received via the reading port 23b. Therefore, the same reference numerals are given to the components substantially the same as those in the first embodiment, and the description thereof will be omitted.

As shown in FIG. 14, a switch 70 is provided on the bottom 41 of the mounting portion 40 as a detecting means for detecting that the mounting portion 40 is separated from the mounting surface. The switch 70 is configured to output a predetermined signal to the control unit 51 when the bottom portion 41 is separated from the mounting surface. The control unit 51 receives light from the light receiving sensor 63a via the reading port 23a and receives light from the light receiving sensor 63b via the reading port 23b according to the signal (detection result) from the switch 70. To switch. In this embodiment, the trigger button 54a can be abolished.

As a result, the light receiving state for mounting can be switched to the light receiving state for carrying by simply grasping and lifting the grip portion 30 without operating the trigger button 54a or the like, or the mounting portion 40 can be mounted on the mounting surface. It is possible to switch from the light receiving state for carrying to the light receiving state for mounting just by doing so.

The switch 70 provided on the bottom 41 is not limited to the detection means for detecting that the mounting portion 40 is separated from the mounting surface. For example, an acceleration sensor, a capacitance sensor, a geomagnetic sensor, etc. May be adopted. Even in this way, the control unit 51 receives light from the light receiving sensor 63a via the reading port 23a and a light receiving state from the light receiving sensor 63b via the reading port 23b, depending on the detection result of the detection means. And can be switched.

The present invention is not limited to the above embodiments and modifications, and may be embodied as follows, for example.
(1) The optical unit 60 has a light receiving sensor 63a that receives the reflected light from the information code via the reading port 23a and a light receiving sensor 63b that receives the reflected light from the information code through the reading port 23b, respectively. It may be configured to have one light receiving sensor (light receiving means) capable of receiving both reflected light by using a reflecting mirror or the like.

(2) Further, even if the trigger button 54a and the switch 70 are abolished and the light receiving sensor 63a and the light receiving sensor 63b are constantly controlled to receive the reflected light from the information code via the reading port 23a and the reading port 23b. Good. Further, in the above (1), one light receiving sensor capable of receiving both reflected light may be controlled so that the reflected light from the information code can always be received via the reading port 23a and the reading port 23b. As a result, the reflected light from the desired information code can be received by the light receiving sensor regardless of which reading port is used at any time without performing any special operation or the like.

(3) The light receiving sensor 63a may be set so that the light receiving range Sa is longer in the vertical direction than the length in the horizontal direction when mounted on the mounting portion 40. When an article or the like with an information code is held over the reading port 23a, the article or the like is often held over the reading port 23a from the left-right direction, so that the article or the like is held up and down with respect to the reading port 23a. It often shifts. Even in such a case, since the length of the light receiving range Sa in the vertical direction is set to be longer than the length in the horizontal direction, the influence of the vertical deviation on the reading port 23a of the information code can be suppressed. , The reflected light from the information code can be reliably received through the reading port 23a.

(4) The light receiving sensor 63b is not limited to being configured as a line sensor as described above, but may be configured as an area sensor like the light receiving sensor 63a.

(5) The housing 11 is not limited to the reading unit 20 having the extending portion 24, and the reading unit 20 is provided with the first reading port on the first surface and with respect to the first surface. It may be formed so that the second reading port is provided on the second surface on the opposite side. For example, the reading unit 20 may be formed so that the first reading port is provided on the flat front surface and the second reading port is provided on the flat rear surface.

(6) The information read by the optical information reading device 10 is not limited to the information code, and may be optically readable optical information such as character information.
