The display unit housing 1A is slidably attached to the operation unit housing 1B.

  That is, the display unit casing 1A and the operation unit casing 1B are arranged so as to overlap in the vertical direction (in the drawing, the direction perpendicular to the paper surface). One body of the body 1B, that is, the operation unit housing 1B is fixed to the wrist mounting unit 2. As shown in FIG. 2, the other casing superimposed on the operation section casing 1 </ b> B, that is, the display section casing 1 </ b> A has the casing 1 mounted on the wrist via the wrist mounting section 2. In this state, it is slidable (reciprocally movable) in the length direction (straight direction) of the forearm from the wrist to the elbow with respect to the operation unit casing 1B.

  FIG. 3 shows a state in which the display unit housing 1A and the operation unit housing 1B overlap each other (a state in which the operation unit housing 1B is closed). In this case, the key operation unit 4 on the operation unit casing 1B is completely covered with the display unit casing 1A. FIG. 1A shows a state in which the display unit housing 1A is slid in a linear direction from the wrist to the elbow from a state in which the operation unit housing 1B is closed (a state in which the operation unit housing 1B is opened). . In this case, the key operation unit 4 on the operation unit housing 1B is exposed. FIG. 1B is a diagram showing an arrangement state of keys on the key operation unit 4, and various keys are arranged in a 3 × 4 matrix. That is, various keys such as a numeric keypad for inputting numerical values, an alphabet key for inputting alphabetic characters, and a kana key for inputting kana characters are arranged on the key operation unit 4 as shown in the illustrated example. The touch display unit 3 has display screens having different aspect ratios, and is arranged such that the longitudinal direction of the screen is along the longitudinal direction of the display unit housing 1A.

  The wrist mounting portion 2 supports (cantilever) the housing 1 and has a bridge plate 2A, a connecting piece 2B, a fastener 2C, and a flexible band 2D as shown in FIG. . That is, the bridge plate 2A is fixed to one end portion in the longitudinal direction of the operation unit casing 1B along a direction orthogonal to the longitudinal direction. This bridge plate 2A is formed by bending both end portions of a belt-like flat plate obliquely downward, and one end portion of the corresponding connecting piece 2B, 2B is rotatable in each bent portion (extending portion). Screwed. Corresponding fasteners 2C and 2C are rotatably attached to the other ends of the connecting pieces 2B and 2B.

The wrist mounting portion 2 configured as described above is placed with the scanner device standing up when the scanner device is placed on a desk or the like. That is, when the casing 1 is removed from the wrist and placed with the wrist mounting portion 2 facing down, the flexible band 2D is bent so as to be crushed by the weight of the scanner device. By opening 2B and 2B in a divergent shape (opening in an eight-letter shape), the scanner device is supported and supported by the wrist mounting portion 2.

  The optical component 5 is an optical element that constitutes a scanner unit that optically scans a reading target (code information such as a bar coat and a two-dimensional code). If a laser scanner, a light emitting element that emits laser light; The light receiving element receives the reflected light. Note that the optical component 5 is an optical system (such as a photographic lens) that constitutes an image capturing unit that captures an image of a subject in the case of an image scanner including an image sensor as well as a laser scanner unit. As shown in FIG. 2, such an optical component 5 has the wrist mounting portion 2 positioned on the side surface of the wrist on the little finger side when the housing 1 is mounted on the wrist via the wrist mounting portion 2. It is provided on one side. That is, the optical component 5 is arranged in a state where the tip of the optical component 5 is exposed from one bent portion (extending portion) of the bridge plate 2A, that is, the bent portion (extending portion) on the little finger side of the wrist. It is installed.

  Here, when the user reads the reading target with the scanner device, when the elbow is bent so that the wrist on the side on which the scanner device is mounted is in front of the chest in front of the position of the reading target, It becomes a readable state. In this state, when the scanner start key ST is operated, the scanner device starts a scanning operation for scanning a barcode on the condition that the scanner device is in a specific posture, which will be described later. The scanner start key ST is provided at or near the wrist attachment portion 2, and in the example shown in the figure, the case where the scanner start key ST is provided at substantially the center of the upper surface of the bridge plate 2A is shown. In the vicinity of the scanner start key ST, there is provided an identification display portion (light emitting diode) LD for identifying and displaying in which direction the optical component 5 is directed when the scanner start key ST is operated. Yes. In the illustrated example, a case where a bar-shaped identification display portion (light emitting diode) LD is provided on the optical component 5 side on the upper surface of the bridge plate 2A is shown.

FIG. 5 is a block diagram illustrating basic components of an arm-mounted scanner device.
The scanner device includes a power source unit 12, a storage unit 13, a memory 14, a touch display unit 3, a key operation unit 4, a scanner unit 15, a communication unit 16, a contact sensor unit 17, and an acceleration sensor unit 18 with the CPU 11 as a core. It has become. The CPU 11 operates by supplying power from the power supply unit (secondary battery) 12 and controls the overall operation of the scanner device according to various programs in the storage unit 13.

  The storage unit 13 includes a ROM, a flash memory, and the like, for example. In addition to an operation system (OS), a program and various applications for realizing the present embodiment according to an operation procedure illustrated in FIG. Etc. are stored. The storage unit 13 may be configured to include a removable portable memory (recording medium) such as an SD card or an IC card, and is connected to a network via a communication function (not shown). May include a storage area on a predetermined external server side. The memory 14 is a work area for temporarily storing various types of information necessary for the operation of the scanner device, such as timing information and flag information.

  The touch display unit 3 constitutes touch input means (touch screen) for detecting a position touched with a finger or a pen and inputting coordinate data thereof, and includes a display panel 3A and a touch panel 3B. . The display panel 3A is, for example, a high-definition liquid crystal display or an organic EL (Electro Luminescence) display that displays function names as software keys, and displays objects (icons, links, etc.). Display of 240 × 360 dots is possible. The touch panel 3B may be any one of a capacitance method, a resistance film method, an electromagnetic induction method, a piezoelectric method, and the like.

  The key operation unit 4 includes the various keys described above, and the CPU 11 performs processing according to input operation signals from the touch display unit 3 and the key operation unit 4. The scanner unit 15 optically reads code information such as a bar code (one-dimensional code) and a QR code (two-dimensional code). Although not shown, the light-emitting element that emits laser light and its reflected light are received. The CPU 11 recognizes the code information by analyzing (decoding) the code information (image information) read by the scanner unit 15. The communication unit 16 is connected to a host device (not shown) via a wireless LAN (local communication network), and transmits / receives data to / from the scanner device.

  The contact sensor unit 17 detects a state in which the scanner device is attached to the hand (human body contact state) by means of, for example, electrostatic capacity, optical, resistance, or mechanical means. When the wrist mounting part 2 is mounted on the hand, it is provided on the back surface side (contact surface side in contact with the vicinity of the wrist) of the operation unit housing 1B. The acceleration sensor 18 is a three-axis type configuration that detects the posture of the scanner device, detects whether the posture of the scanner device (housing 1) is substantially horizontal with respect to the direction of gravity, or detects how to receive an impact. Detect whether it is in a state of sudden stop.

  The CPU 11 determines whether the scanner device (housing 1) is in a substantially horizontal state as a user operation for reading code information in a state where the housing 1 is attached to the wrist via the wrist attaching portion 2. Whether or not the vehicle is suddenly stopped is determined based on the detection result of the acceleration sensor 18. For example, based on the detection result of the acceleration sensor 18, whether or not the operation of bending the elbow and making the forearm substantially horizontal so that the wrist wearing the scanner device is near the front of the chest has been performed. I try to distinguish. Note that the position of the wrist is not limited to the case where the wrist is in front of the chest but the wrist is in front of the abdomen or diagonally in front of the chest, and the scanner device may be positioned in front of the reading target. .

  Next, the operation concept of the scanner device in the first embodiment will be described with reference to the flowchart shown in FIG. Here, each function described in this flowchart is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via a transmission medium such as a network can be sequentially executed. In other words, in addition to the recording medium, an operation unique to the present embodiment can be executed using a program / data supplied externally via a transmission medium.

FIG. 6 is a flowchart showing an outline of the overall operation of the scanner apparatus that is started in response to power-on.
First, the CPU 11 acquires the detection result of the contact sensor unit 17 (step S1), and based on the detection result, is the CPU 11 in contact with the human body, that is, the contact sensor unit 17 is placed on the back surface of the operation unit housing 1B. Therefore, based on the detection result, it is checked whether the scanner device is attached to the hand (step S2). If the scanner device is not attached to the hand (NO in step S2), the presence / absence of key operation from the touch display unit 3 or the key operation unit 4 is checked (step S3). If no key is operated (NO in step S3), the process returns to the first step S1 described above. However, when any key operation is performed (YES in step S3), processing corresponding to the operation is performed. For example, after performing various setting processes (step S4), the process returns to the first step S1.

  If the scanner device is worn on the hand (YES in step S2), the detection result of the acceleration sensor unit 18 is acquired (step S5), and the posture of the scanner device is based on the detection result with respect to the direction of gravity. It is checked whether the vehicle is in a substantially horizontal state and is in a sudden stop state (step S6). That is, as a user's action, in order to read the code information, for example, the forearm is bent almost horizontally so that the wrist wearing the scanner device comes to the front of the chest, and the forearm is substantially horizontal and is stopped suddenly. Find out if an action has taken place. The substantially horizontal state is, for example, in the range of about plus / minus 20 ° with respect to the horizontal, but is not limited thereto, and may be in the range of about plus / minus 45 °.

  Here, if the scanner device is in a substantially horizontal state and is not in a sudden stop state (NO in step S6), it is determined that the user operation is not an operation for reading the code information, and the key The process proceeds to the above-described step S3 in order to check whether or not there is an operation. If the scanner device is in a substantially horizontal state and is in a state of sudden stop (YES in step S6), the user operation for reading the code information Is determined to have been performed, and the operation of the scanner start key ST is awaited (step S7). In this state, when the scanner start key ST is operated (YES in step S7), the identification display section LD is turned on (step S8), and the scanner section 15 is activated (step S9). The code information read by is acquired and decoded (step S10). Then, after processing for storing and displaying the decoded result and displaying (step S11), the process returns to the above-mentioned first step S1, and the above-described operation is repeated thereafter.

  As described above, in the scanner device according to the first embodiment, the wrist provided on the one end side so that the one end side in the longitudinal direction of the plate-like housing 1 is a fixed end and the other end side is a free end. Provided so as to be located on the side of the wrist on the little finger side when the mounting unit 2, the touch display unit 3 provided on the casing 1, and the casing 1 is mounted on the wrist through the wrist mounting unit 2 Even if the casing 1 is lengthened along the longitudinal direction of the forearm in a state where the casing 1 is mounted on the wrist, the casing becomes an obstacle when the wrist is bent. In addition, the improvement in operability can be expected, and the touch display unit 3 can be increased in size by lengthening the housing 1, and the practicality of the reading work is improved. Become.

  The housing 1 is a rectangular plate-like member having different vertical and horizontal lengths, and the touch display unit 3 has display screens having different aspect ratios, and the longitudinal direction of the display screen is along the longitudinal direction of the housing 1. Since the touch display unit 3 is arranged on the housing 1 as described above, the display screen can be enlarged.

  In the state where the casing 1 is mounted on the wrist via the wrist mounting portion 2, the casing 1 is provided so that its longitudinal direction is along the direction from the wrist to the elbow. In addition to the display unit 3, the key operation unit 4 can be provided.

  The optical component 5 is an optical element that constitutes a scanner unit that optically scans an object to be read. When the housing 1 is mounted on the wrist via the wrist mounting unit 2, the optical component 5 is provided on the side surface of the wrist on the little finger side. Since it is provided on one side of the wrist mounting part 2 so as to be positioned, the sleeve part of the user's clothes does not get in the way, and the optical component 5 faces the reading object positioned in front of the user. Can be directed to the reading target. Therefore, for the user, the optical component 5 is directed to the reading target located in front of the user by simply bending the elbow at a substantially right angle so that the wrist to which the housing 1 is attached is in front of the chest. In addition, it is possible to easily adjust the directivity direction of the optical component 5 by simply rotating the forearm so as to twist it, so that improvement in operability can be expected and the scanning operation can be performed efficiently. It becomes possible and it becomes rich in practicality. Furthermore, since reading is performed with the elbow bent at a substantially right angle, the scanner device is stably prevented from blurring, and the reading can be performed appropriately.

  The housing 1 has a configuration in which a display unit housing 1A including a touch display unit 3 and an operation unit housing 1B including a key operation unit 4 are slidably mounted. The housing 1 is interposed via a wrist mounting unit 2. The display unit housing 1A and the operation unit housing 1B are slidably attached to the other housing in the direction from the wrist to the elbow. Therefore, even if the touch display unit 3 and the key operation unit 4 are enlarged, the entire housing 1 can be made compact, and a significant improvement in usability can be expected.

  Since the scanner device is provided with the scanner start key ST for instructing the start of processing using the optical component 5 on the upper surface of the wrist mounting portion 2, the sleeve portion of the user's clothes is not obstructed, and the operability is improved. Improvement can be expected.

  Since the CPU 11 lights the identification display portion (light emitting diode) LD when the scanner start key ST is operated, the CPU 11 can clearly indicate whether or not the optical component 5 is facing. 5 can be accurately directed to the reading target.

  In the scanner device, the contact sensor unit 17 that detects a state in which the housing 1 is attached to the wrist via the wrist attaching portion 2, the forearm to which the housing 1 is attached is in a substantially horizontal state, and the forearm And the acceleration sensor unit 18 for detecting the sudden stop state as an operation of the scanner, and the operation of the scanner start key ST is validated based on the detection results of the contact sensor unit 17 and the acceleration sensor unit 18. The scanner starts a pose for reading the subject (code information) for the user (posture with the elbow bent approximately at a right angle so that the wrist on which the housing 1 is attached is in front of the chest) It can be a precondition for enabling the operation of the key ST, and erroneous operation of the key can be prevented.

  When the scanner device 1 is removed from the wrist and placed with the wrist mounting portion 2 facing down, the scanner device is bent so that the flexible band 2D is crushed by its own weight. Since the connecting pieces 2B and 2B are opened in a divergent shape (opened in an eight-letter shape), the scanner device is supported by the wrist mounting portion 2 so that it stands up. When placing on a surface, etc., the scanner device can be placed upright, reducing the contact surface with the desk surface, etc. It can be mounted without change, and the handling of the scanner device is also convenient.

  In the first embodiment described above, the scanner start key ST is provided on the upper surface of the wrist mounting portion 2, but the arrangement position is not limited to the upper surface of the wrist mounting portion 2, and is arbitrary. That is, in a state where the housing 1 is mounted on the wrist via the wrist mounting portion 2, for example, the housing 1 may be disposed on one side of the wrist mounting portion 2 on the thumb side. The position is not limited, and any position may be used as long as it can be expected to improve operability.

  In the first embodiment described above, the detection results by the contact sensor unit 17 and the acceleration sensor unit 18 are used as the preconditions for validating the operation of the scanner start key ST, but the contact sensor unit 17 and the acceleration sensor are used. The scanner unit 15 may be automatically activated based on the detection result by the unit 18. That is, it is detected by the contact sensor unit 17 that the housing 1 is mounted on the wrist via the wrist mounting unit 2, and the forearm on which the housing 1 is mounted by the acceleration sensor unit 18 is substantially the same. The scanner unit 15 may be activated when it is detected that the state is a horizontal state and the state of the forearm being suddenly stopped. As a result, the user can start the scanner operation only by taking a posture in which the elbow is bent at a substantially right angle so that the wrist on which the housing 1 is mounted is in front of the chest. The work can be performed more efficiently. In this case, if the step S7 waiting for the operation of the scanner start key ST is deleted in the flowchart of FIG. 6, the above-described automatic start can be realized. For example, the reading operation of the scanner unit 15 may be terminated by performing an operation of lowering the forearm.

  In addition, when it is detected that the forearm is in a substantially horizontal state and is in a sudden stop state, the laser beam is emitted by key operation after informing the reading position of where the laser beam is irradiated with a spot beam. You may make it irradiate. Alternatively, after the reading position is illuminated by spot light irradiation, the reading position may be irradiated with laser light on condition that a certain time (for example, 2 seconds) elapses.

  Further, the scanner unit 15 may be automatically activated not only when the scanner unit 15 is automatically activated on the condition that the forearm is suddenly stopped, but only when the forearm is in a substantially horizontal state. That is, the contact sensor unit 17 detects that the case 1 is attached to the wrist via the wrist attachment unit 2, and the forearm to which the case 1 is attached by the acceleration sensor unit 18 is substantially the same. The scanner unit 15 may be activated when the horizontal state is detected. Accordingly, the user can start the scanner operation only by taking the posture in which the forearm on the side on which the housing 1 is mounted is in a substantially horizontal state, and the work can be performed more efficiently.

  In addition, the acceleration sensor unit 18 may detect that the forearm is in a substantially horizontal state and a state where the forearm is rotated in a substantially horizontal state. For example, rotation for twisting the forearm in a substantially horizontal state may be detected. In this case, it is detected by the contact sensor unit 17 that the case 1 is attached to the wrist via the wrist attachment unit 2 and the forearm on which the case 1 is attached by the acceleration sensor unit 18 The scanner unit 15 may be activated when a substantially horizontal state is detected and a rotated state is detected.

  Thus, the user twists the forearm in order to point the optical component 5 toward the reading target located on the lower side of the forearm, with the forearm on the side on which the housing 1 is mounted being substantially horizontal. Thus, the scanner operation can be started simply by rotating, and the work can be performed more efficiently. In this case, while maintaining the state where the forearm is twisted (the state in which the optical component 5 is directed toward the reading target), a plurality of reading targets can be read continuously by keeping the scanner operating. It becomes possible.

In the first embodiment described above, the optical component 5 is provided on one side surface of the wrist mounting portion 2, but the optical component 5 may be disposed on both side surfaces of the wrist mounting portion 2.
FIG. 7 is an external view (top view) of the scanner device in this case as viewed from above. That is, one optical component 5 is disposed on one side surface of the wrist mounting portion 2 so as to be positioned on the side surface of the wrist on the little finger side when the housing 1 is mounted on the wrist via the wrist mounting portion 2. Furthermore, the other optical component 5 may be disposed on the other side surface of the wrist mounting portion 2 so as to be positioned on the side surface of the wrist on the thumb side. In this manner, by arranging the optical components 5 on both side surfaces of the wrist mounting portion 2, it is possible to cope with both right-handed users and left-handed users.

  In the above-described first embodiment, the display unit housing 1A including the touch display unit 3 and the operation unit housing 1B including the key operation unit 4 are slidably attached. Is not divided into the display unit housing 1A and the operation unit housing 1B, and the touch display unit 3 and the key operation unit 4 may be provided side by side on one housing 1.

(Second Embodiment)
Hereinafter, a second embodiment of the present invention will be described with reference to FIGS.
In the first embodiment described above, the display unit casing 1A overlaid on the operation unit casing 1B is configured to be slidable along the longitudinal direction of the forearm. In the embodiment, the display unit casing 1A superimposed on the operation unit casing 1B is rotatably attached. Here, in both the embodiments, the same or the same names are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

8 to 10 are external views of an arm-mounted type scanner device. 8 and 9 are external views (top views) of the arm-mounted scanner device viewed from above, and FIG. 9 shows a state where the scanner device is mounted on the wrist. FIG. FIG. 10 is an external view (one side view) of the scanner device viewed from the side.
The scanner device optically scans a reading target (code information such as a barcode), and includes a plate-shaped casing 1, a wrist mounting unit 2, a touch display unit 3, a key operation unit 4, and an optical component 5. It has a configuration. In other words, the scanner device has a plate-like housing 1 and one end side (right side in the figure in the figure: right and left direction in the example shown in the drawing) as a fixed end and the other end side (in the figure). , The left side) to be a free end, a wrist attachment part 2 provided on the one end side, a touch display part 3 and a key operation part 4 provided on the case 1, and the case 1 the wrist attachment part 2 And an optical component 5 provided so as to be positioned on the side surface of the wrist on the little finger side in a state of being mounted on the wrist.

  The casing 1 is a rectangular plate-like member having different vertical and horizontal lengths, and has a cantilever structure in which the other end side in the longitudinal direction of the casing 1 is fixed to the wrist mounting portion 2. In a state in which the housing 1 is mounted on the wrist via the wrist mounting portion 2, the casing 1 is arranged so that the longitudinal direction of the housing 1 is along the straight direction from the wrist to the elbow. As shown in FIG. 9, the housing 1 is divided into two housings, and a display unit housing 1 </ b> A having a touch display unit 3 and an operation unit housing 1 </ b> B having a key operation unit 4. The display unit casing 1A is attached to the operation unit casing 1B so as to be capable of rotating by 90 ° in the clockwise direction and the counterclockwise direction, respectively.

  That is, the rotation support unit 6 is configured to rotatably attach the housing 1 to the wrist mounting unit 2, and the housing 1 can be rotated with the rotation support unit 6 as a fulcrum. In this case, the display unit casing 1A and the operation unit casing 1B are arranged so as to overlap in the vertical direction (in the drawing, the direction perpendicular to the paper surface). One body of the body 1B, that is, the operation unit housing 1B is fixed to the wrist mounting unit 2. The other casings overlaid on the operation unit casing 1B, that is, the display unit casing 1A can be rotated 90 ° clockwise and counterclockwise with respect to the operation unit casing 1B. It becomes.

  In other words, as shown in FIG. 9, in the state where the housing 1 is attached to the wrist via the wrist attachment portion 2, the longitudinal direction of the display portion housing 1A is arranged along the direction from the wrist toward the elbow. It is possible to change from the state where the key is operable (a state where keys can be operated) to a state where the longitudinal direction of the display unit housing 1A is arranged along a direction substantially orthogonal to the direction from the wrist to the elbow (scannable state) It has become. Here, although not shown in the drawing, the rotation support portion 6 can rotate a mounting hole formed in one end portion of the display portion housing 1A to a protruding portion (support shaft portion) from one end portion of the operation portion housing 1B. Although the structure is fitted, the method of attachment is not limited to this and is arbitrary.

  In addition, the display unit casing 1A and the operation unit casing 1B overlap each other vertically (key operation possible state: see FIG. 8), and the display unit casing 1A rotates 90 ° with respect to the operation unit casing 1B. In this state (scanning enabled state: see FIG. 9), the display unit housing 1A and the operation unit housing 1B are elastically locked. That is, although not shown in the drawing, the locking projection formed on the display unit housing 1A (elastic body) is locked in the locking hole formed on the operation unit housing 1B side. The casing 1A and the operation unit casing 1B are elastically locked to maintain the key operable state shown in FIG. 8 and the scanning enabled state shown in FIG. In either state, the locking projection and the locking hole are unlocked by rotating the display housing 1A clockwise or counterclockwise against the elastic force. It is like that.

  An optical component 5 is disposed at the distal end portion (left end portion in the case of FIG. 8) of the display unit housing 1A. In this case, as shown in FIG. 10, the front end portion of the display unit housing 1A is slightly bent toward the diagonally lower side in the figure, and the optical component 5 is placed in the front end portion (folded portion). It is stored with its tip exposed. In other words, the optical component 5 is disposed on the free end side of the display unit housing 1A that is rotatably supported via the rotation support unit 6, and the optical component 5 is in a state where the housing 1 is horizontal. The tip portion is stored so as to be directed obliquely downward.

  As shown in FIG. 9, when the optical component 5 is disposed at the tip of the display unit casing 1A in this manner and the display unit casing 1A is rotated 90 ° with respect to the operation unit casing 1B. In addition, the optical component 5 is positioned on the side surface of the wrist on the little finger side. In FIG. 8, an arrow A indicates a clockwise direction, an arrow B indicates a counterclockwise direction, and for a right-handed user, the display unit housing 1A is rotated in the clockwise direction A, and left-handed. For example, the display unit housing 1A may be rotated in the counterclockwise direction B. FIG. 9 is an example of use by a right-handed user, in which the display unit housing 1A is rotated in the clockwise direction A. The wrist mounting portion 2 is a flexible band made of metal or synthetic resin, and the operation unit housing 1B is fixed to the central portion of the band.

  As described above, in the second embodiment, the rotation support portion 6 that rotatably attaches the housing 1 to the wrist mounting portion 2 is provided, and the housing 1 can be rotated using the rotation support portion 6 as a fulcrum. Therefore, in a state where the housing 1 is attached to the wrist via the wrist attaching portion 2, the case 1 is arranged so that the longitudinal direction of the housing 1 is along the direction from the wrist to the elbow, and from the wrist to the elbow. By changing to a state of being arranged along a direction substantially orthogonal to the direction of heading, the optical component 5 provided at the tip of the display unit housing 1A is positioned on the side surface of the wrist on the little finger side. . Thus, even when the housing 1 is rotatably attached to the wrist mounting portion 2, the same effects as those of the first embodiment described above are obtained. That is, even if the casing 1 is elongated along the length direction of the forearm in a state where the casing 1 is attached to the wrist, the casing 1 does not get in the way when the wrist is bent and the operability is improved. In addition, it is possible to increase the size of the touch display unit 3 by making the housing 1 longer, and the practicality of the reading operation becomes high.

  The housing 1 includes a display unit housing 1A having a touch display unit 3 and an operation unit housing 1B having a key operation unit 4, and either the display unit housing 1A or the operation unit housing 1B. Since the housing is rotatably attached with the rotation support portion 6 as a fulcrum, even if the touch display portion 3 and the key operation portion 4 are enlarged, the entire housing 1 can be made compact and easy to use. Significant improvement can be expected.

  Since the rotation support unit 6 is attached to the wrist mounting unit 2 so as to be rotatable in both the clockwise direction and the counterclockwise direction, the rotation support unit 6 can accommodate both right-handed users and left-handed users. It becomes.

  In the second embodiment described above, the display unit casing 1A is rotatably attached to the operation unit casing 1B using the rotation support unit 6 as a fulcrum. The body 1B may be rotatably attached to the display unit housing 1A. In this case, the optical component 5 may be provided on the distal end (free end) side of the operation unit casing 1B. Furthermore, the touch display unit 3 and the key operation unit 4 may be arranged side by side on one case 1 without dividing the case 1 into the display unit case 1A and the operation unit case 1B.

  In each of the above-described embodiments, the optical component 5 is shown as an optical element that constitutes a scanner unit that optically scans a bar coat or the like. However, the optical component 5 is not limited to the optical element that constitutes the scanner unit, and the subject is imaged. It may be an optical system (such as a photographing lens or a prism) that constitutes an imaging unit (camera unit). Thus, by using the optical component 5 as an optical system of the imaging unit (camera unit), an arm-mounted imaging device (camera device) can be provided as a portable terminal device that can be worn on the wrist. In this case, the optical component 5 can be accurately directed to the position of the subject by the movement of the forearm (rotational motion that twists the forearm, etc.), and it is also possible to perform shooting efficiently without being noticed by the subject.

  In each of the above-described embodiments, the case where the present invention is applied to the scanner device has been described. However, the present invention is not limited to the scanner device and the imaging device, and may be a portable terminal device such as a PDA / music player with a camera function.

  Further, the “apparatus” and “unit” shown in each of the above-described embodiments may be separated into a plurality of cases by function, and are not limited to a single case. Further, each step S described in the above-described flowchart is not limited to time series processing, and a plurality of steps S may be processed in parallel or separately.
