Description

  The present invention relates to an electronic device.

Conventionally, a recording apparatus having a wireless communication function is known. In order to perform wireless communication, it is necessary to provide the recording apparatus with an antenna for wireless transmission and reception at an appropriate position. For example, in the recording apparatus described in Patent Document 1, a part of the exterior is a cover that can be opened and closed, and a part of the cover includes an antenna.
JP2002-120430A

  However, radio waves transmitted and received based on the conventionally used Bluetooth (registered trademark) standard have a narrow reception angle when received by a chip antenna. As for radio wave reception, if an object that reflects radio waves such as metal exists close to the antenna, the reception state becomes very bad due to interference of reflected waves and the like. For this reason, there was a problem that the user had to install it at a position suitable for receiving radio waves.

  The present invention has been made in view of such an invention, and an object of the present invention is to provide an electronic device in which a chip antenna is positioned at a position suitable for reception of radio waves without bothering a user during use. To do.

  The present invention adopts the following means in order to achieve the above-mentioned object.

The electronic device of the present invention is
An electronic device that is pivotally attached to a support shaft provided in the electronic device main body and that rotates around the support shaft from a closed position that covers the upper surface of the electronic device main body exposes the upper surface of the electronic device to the outside. A cover reaching an open position where the angle with the installation surface exceeds 90 °;
A chip antenna used when the receiving device receives data based on a Bluetooth standard with an external device;
The chip antenna is provided, and when the cover is in the closed position, the cover is pressed by the cover and positioned at an unused position in contact with the lower surface of the cover, and when the cover rotates from the closed position to the open position, An antenna case positioned at a use position standing up to approximately 90 ° from the unused position with respect to the electronic device installation surface;
It is equipped with.

  In this electronic apparatus, a receiving device receives data based on the Bluetooth standard with an external device via a chip antenna provided in the antenna case. Here, when the cover is in the closed position, the antenna case is pressed by the cover and positioned at an unused position in contact with the lower surface of the cover. On the other hand, when the user opens the cover from the closed position to the open position, the antenna case moves from the unused position to a use position that stands at approximately 90 ° with respect to the electronic device installation surface. According to the experiments of the present inventors, when receiving data based on the Bluetooth standard using a chip antenna, when the chip antenna is erected so as to be approximately 90 ° with respect to the electronic device installation surface, from all directions I know I can receive data. Therefore, the chip antenna can be positioned at a position suitable for receiving radio waves without bothering the user.

  In the electronic device of the present invention, the antenna case is rotatably attached to a case shaft provided in the electronic device main body, and the angle of the cover from the closed position to the electronic device installation surface is approximately 90 °. It rotates from the unused position to the used position in conjunction with the cover up to the vertical position, and then stays in the used position without interlocking with the cover until the cover reaches the open position from the vertical position. It may be a thing. In this way, the chip antenna can be positioned at a use position suitable for receiving a radio wave in accordance with an operation performed when the cover is opened. At this time, the case shaft may be shared with the support shaft. If it carries out like this, the same effect can be acquired with fewer members.

  An electronic device according to the present invention includes a biasing member that biases the antenna case from the unused position toward the use position, and a rotation prevention member that prevents the antenna case from rotating beyond the use position. The antenna case rotates from the unused position to the used position in conjunction with the cover by being biased by the biasing member until the cover reaches the vertical position from the closed position. Then, the cover may be positioned at the use position without being interlocked with the cover by being prevented from rotating by the rotation preventing member until the cover reaches the open position from the vertical position. If it carries out like this, since the antenna case is positioned in a use position in the state pressed against the rotation prevention member by the biasing member, the antenna position in use can be fixed.

  In the electronic device of the present invention, when the cover is in the closed position, the antenna case is pressed into a state of being immersed in the main body by the cover, and the cover rotates from the closed position to the open position. Along with this, it may protrude to the upper side of the electronic device main body and move to the use position where the angle with the electronic device installation surface is approximately 90 °. In this way, the antenna case can be positioned at the use position with a simpler configuration.

  In the electronic device of the present invention, the antenna case may be housed in a housing space formed between the electronic device body and the cover when the antenna case is in the unused position. This can prevent the antenna case from being damaged when not in use.

  In the electronic apparatus according to the present invention, the electronic apparatus may be a printing apparatus including a printing mechanism capable of printing based on print data received by the chip antenna. In this way, printing can be performed based on the data received by the chip antenna.

  The electronic device of the present invention may include a battery capable of supplying power to each unit. Since such an electronic device includes a battery, it can be carried. For example, when receiving data from an external device fixed at a certain location with the chip antenna of the electronic device, the positional relationship between the chip antenna and the external electronic device changes depending on the carrying of the electronic device. Since the posture is such that data from the device can be received, that is, the device is positioned at approximately 90 ° with respect to the electronic device installation surface, the electronic device can receive the data satisfactorily.

  Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 3 is a perspective view of the photo printer 10 with the front door 14 and the cover 30 closed, and FIG. 4 is an explanatory view for explaining the connection between the antenna case 41 and the case support 44.

  As shown in FIG. 1, the photo printer 10 according to the present embodiment includes an operation panel 20 provided on the upper surface of the printer body 12, a front door 14 that can open and close the front surface of the printer body 12, and an upper surface of the printer body 12. The cover 30 is attached to one side of the back so as to be openable and closable and covers the operation panel 20 in the closed state, and is connected to a case support 44 (see FIG. 4) that is pivotally attached to one side of the top of the printer main body 12. Antenna case 41, a battery 60 for supplying power to each part of the photo printer 10, a printing mechanism 50 (see FIG. 2) built in the printer main body 12, and a controller 70 (see FIG. 2) that controls the entire photo printer 10. 2). In this embodiment, the printing medium is described as “recording paper”, but it is not intended to specify the material, but includes other materials such as a film other than paper.

  The operation panel 20 includes a display 22 that displays characters, graphics, symbols, and the like, and a button group 24 arranged around the display 22. As shown in FIG. 2, the button group 24 switches the power button 24a for turning on / off the power, the display size of an image or the like displayed on the display 22 to 6-split display, 15-split display, full-screen display, or the like. A display switch button 24b for displaying, a menu button 24c for calling a main menu screen on which a plurality of options relating to the printing function are arranged, and a cancel for canceling the operation or interrupting printing on the recording paper S. A button 24d, a print button 24e for instructing execution of printing on the recording paper S, a save button 24f for saving an edited image or the like in the memory card M inserted in the memory card slot 18, and a plurality of items displayed on the display 22 Up, down, left, and right operated when selecting a desired option or moving the cursor Tan 24g, and it is configured by a the up, down, right and left buttons OK button for being disposed in the center to indicate that it has determined choices selected by the up, down, left, and right buttons 24g of 24g 24h. As shown in FIG. 1, a paper feed port 58 of the printing mechanism 50 is provided at the back of the operation panel 20, and the paper feed port 58 has left and right guide widths that match the width of the recording paper S. A pair of paper guides 59a and 59b that are slid in the direction are provided.

  The front door 14 is a lid for opening and closing the front surface of the printer main body 12. As shown in FIG. 1, when the front door 14 is in an open state, the front door 14 is discharged to receive the recording paper S discharged from the front surface of the printer main body 12. In addition to functioning as a tray, various memory card slots 18 provided on the front surface of the printer main body 12 can be used by the user.

  As shown in FIG. 1, the cover 30 is a resin plate formed in a size that can cover the upper surface of the printer main body 12, and has the same size as the antenna case storage space 47 for storing the antenna case 41 and the display 22. And is attached to the cover support shaft 32 so as to be openable and closable. When the cover 30 is in the open position, the lower side of the cover 30 is locked to one side of the upper surface of the printer main body 12 so that the surface of the operation panel 20 is exposed to the outside (see FIG. 1). At this time, the cover 30 is held at a position where the angle with the installation surface of the photo printer 10 exceeds 90 ° (for example, 120 to 140 °). For this reason, the back surface of the cover 30 in the open position can be used as a tray for supplying the recording paper S to the printing mechanism 50. On the other hand, when the cover 30 is in the closed position, the antenna case 41 is stored in the antenna case storage space 47 and covers the operation panel 20 (see FIG. 3). At this time, the window 34 provided in the cover 30 allows the user to check the display content of the display 22 through the window 34 when the cover 30 is in the closed position.

  As shown in FIG. 4, the antenna case 41 includes a USB male connector 41c for exchanging data between the chip antenna 41a and the transmitter / receiver 41b for transmitting and receiving radio waves based on the Bluetooth standard and the controller 70 via the USB. And. The antenna case 41 is integrated with the case support 44 by inserting the USB male connector 41 c into the USB female connector 44 a provided on the case support 44. The case support 44 is rotatable around the cover support shaft 32 by a cylindrical portion 44 b inserted through the cover support shaft 32. That is, the case shaft of the antenna case 41 is shared with the cover support shaft 32. The case support 44 has a protrusion 44c on the opposite side of the cylindrical portion 44b from the side where the USB female connector 44a is provided. For this reason, from the state in which the case support 44 is pressed by the cover 30 and stored in the antenna case storage space 47, the USB female connector 44 a is rotated around the cover support shaft 32 and the USB female connector 44 a is installed on the printer main body 12. When the angle reaches approximately 90 °, the protrusion 44c comes into contact with the stopper 46 integrated with the printer main body 12 to prevent the case support 44 from rotating further. Further, a torsion coil spring 42 is inserted into the cover support shaft 32, and one leg of the torsion coil spring 42 is fixed to the case support 44 and the other leg is fixed to the stopper 46. The torsion coil spring 42 urges the case support 44 in the direction in which it rises from the state pressed against the cover 30.

  The printing mechanism 50 is disposed inside the printer main body 12 and is driven by a timing belt 51 that is looped in the left-right direction as shown in FIG. The ink cartridge 54 mounted on the carriage 53 and individually containing inks of each color such as cyan, magenta, yellow, and black, and the ink supplied from each ink cartridge 54 is pressurized to be applied to the recording paper S from the nozzles. A print head 55 that ejects ink toward the head, and a conveyance roller 56 that feeds the recording paper S supplied from a paper feed port 58 formed on the operation panel 20 to the front door 14 in an open state as a paper discharge tray. Yes. Here, the print head 55 employs a method in which a voltage is applied to the piezoelectric element to deform the piezoelectric element and pressurize the ink. However, a voltage is applied to a heating resistor (for example, a heater) to heat the ink. A method of pressurizing the ink with the generated bubbles may be employed. The carriage 53 includes a paper edge detection sensor 57 that detects left and right edges and upper and lower edges of the recording paper S. The paper edge detection sensor 57 detects the left and right edges of the recording paper S when the carriage 53 scans in the horizontal direction before printing on the recording paper S set in the paper supply port 58 and recognizes the paper width. Or the trailing end of the recording sheet S is detected during printing, and the length of the sheet can be recognized.

  The battery 60 is a secondary battery represented by a chargeable / dischargeable lithium hydrogen battery, a nickel hydrogen battery, or the like. A power supply unit (not shown) is connected to the battery 60, and a voltage converted into a necessary voltage level is supplied to various circuits and devices through the power supply unit.

  As shown in FIG. 2, the controller 70 is configured as a microprocessor centered on the CPU 71, and includes a ROM 72 that stores various processing programs, various data, various tables, a RAM 73 that temporarily stores data, Communication is possible with the flash memory 74 that is electrically rewritable and retains data even when the power is turned off, and the memory card M, the chip antenna 41a, the printing mechanism 50, and the operation panel 20 inserted in the memory card slot 18. An interface 75 (I / F) is provided, and these are connected via a bus 77 so that signals can be exchanged with each other. The controller 70 inputs an image file of the memory card M inserted into the memory card slot 18 and an image file received by the chip antenna 41a, and also detects a detection signal from the paper edge detection sensor 57 of the printing mechanism 50 and an operation panel. Command signals from the 20 button groups 24 are input. The controller 70 stores an edited image or the like in the memory card M, and outputs a control signal to the print head 55 of the printing mechanism 50 and a control signal to the display 22 of the operation panel. A radio wave is transmitted via 41b.

  Next, the operation of the thus configured photo printer 10 of the present embodiment, particularly the operation of the antenna case 41 will be described. 5-7 is explanatory drawing for demonstrating operation | movement of the antenna case 41. FIG. As shown in FIG. 5, when the photo printer 10 is not used, the antenna case 41 is pressed against the cover 30 and urged to the antenna case storage space 47 by the torsion coil spring 42 via the case support 44. By accommodating the antenna case 41 in the antenna case storage space 47 when not in use, the antenna case 41 can be prevented from being damaged. When the photo printer 10 is used, the cover 30 is moved from the closed position to the open position. At this time, the antenna case 41 was urged to the antenna case storage space 47 by the torsion coil spring 42 via the case support 44 while the cover 30 moved to a position of approximately 90 ° with respect to the installation surface of the photo printer 10. The cover 30 moves as the cover 30 moves (see FIG. 6). When the cover 30 further moves from the position shown in FIG. 6 toward the open position, the protrusion 44c is prevented from rotating by the stopper 46, so that the case support 44 cannot rotate to a position of approximately 90 ° or more. . At this time, since the torsion coil spring 42 is urged, the antenna case 41 is positioned at a position of approximately 90 ° via the case support 44. Therefore, as shown in FIG. 7, when the cover 30 is moved to the open position, the antenna case 41 is urged to the use position. Thereby, the chip antenna 41a is positioned at a position of approximately 90 ° suitable for reception of radio waves as the cover 30 is moved to the open position.

  Here, the standing position suitable for data reception when receiving data based on the Bluetooth standard will be described. In order to determine a suitable standing position, as a chip antenna, a Billionton dongle model number GUBTCR42 was installed on a printer cover having a cover capable of adjusting an angle with respect to the printer installation surface. Next, a radio wave transmission PC is prepared at a position 10 m away from the printer. The angle of the radio wave transmission PC with respect to the front of the printer (hereinafter referred to as “PC installation angle”) is set to a predetermined angle of 0 ° to 360 °, and HCRP ( (Hardcopy Cable Replacement Profile) printing was performed, and the time until printing was completed was measured. At this time, the cover to which the chip antenna was attached was fixed at 125 ° and 90 ° with respect to the installation surface of the printer, and the printer and the radio wave transmission PC were installed at a height of 100 cm.

  Table 1 below shows the time required for HCRP printing at each angle as a result of measurement under the conditions described above. In Table 1, “x” represents that the recording paper was discharged during printing and printing could not be performed, and “−” represents that measurement was not performed. From this result, when the chip antenna is at a position perpendicular to the printer installation surface, printing is possible regardless of the PC installation angle, and the printing time is also shorter than when the chip antenna angle is 125 °. For this reason, it can be said that the most suitable angle for printing is that the chip antenna that transmits and receives data based on the Bluetooth standard is erected at an angle of 90 ° with respect to the printer installation surface.

  Here, the correspondence between the components of the present embodiment and the components of the present invention will be described. The photo printer 10 of the present embodiment corresponds to the electronic device of the present invention, the transmission / reception device 41b corresponds to the transmission / reception device, the printer main body 12 corresponds to the electronic device main body, the cover support shaft 32 corresponds to the support shaft, and the cover 30 corresponds to the cover, the chip antenna 41a corresponds to the chip antenna, the antenna case 41 corresponds to the antenna case, the torsion coil spring 42 corresponds to the biasing member, the stopper 46 corresponds to the rotation prevention member, and the antenna case The storage space 47 corresponds to a storage space, the printing mechanism 50 corresponds to a printing mechanism, and the battery 60 corresponds to a battery.

  According to the photo printer 10 of this embodiment described in detail above, the transmission / reception device 41b transmits / receives data to / from the external device based on the Bluetooth standard via the chip antenna 41a provided in the antenna case 41. Here, when the cover 30 is in the closed position, the antenna case 41 is pressed by the cover 30 and positioned at an unused position in contact with the lower surface of the cover 30. On the other hand, when the user opens the cover 30 from the closed position to the open position, the antenna case 41 moves from the unused position to a use position that stands up to approximately 90 ° with respect to the photo printer 10 installation surface. . By doing so, the chip antenna 41a can be positioned at a position suitable for receiving radio waves without bothering the user.

  In addition, the chip antenna 41a can be positioned at a use position suitable for receiving radio waves by an operation performed when the cover 30 is opened. At this time, since the case shaft is shared with the cover support shaft 32, the same effect can be obtained with a smaller configuration.

  Further, the case support 44 is biased to the use position by the torsion coil spring 42 in a state where the projection 44c is in contact with the stopper 46, so that the position of the chip antenna 41a in use can be fixed.

  Furthermore, since the antenna case 41 is stored in the antenna case storage space 47 formed between the printer main body 12 and the cover 30 when in the unused position, the antenna case 41 is damaged when not in use. Can be prevented.

  Further, since the photo printer 10 is a printing apparatus including the printing mechanism 50 that can print based on the print data received by the chip antenna 41a, the photo printer 10 can perform printing based on the data received by the chip antenna 41a.

  Furthermore, since the photo printer 10 includes a battery 60 that can supply power to each unit, the photo printer 10 can be freely carried. For example, when data is received from an external device fixed at a certain location by the chip antenna 41a of the photo printer 10, the positional relationship between the chip antenna 41a and the external electronic device changes by carrying the photo printer 10, but the chip antenna Since 41a is continuously positioned to receive data from an external electronic device, that is, positioned at approximately 90 ° with respect to the installation surface of the photo printer 10, the photo printer 10 can receive data satisfactorily.

  It should be noted that the present invention is not limited to the above-described embodiment, and it goes without saying that the present invention can be implemented in various modes as long as it belongs to the technical scope of the present invention.

  For example, in the above-described embodiment, the inkjet photo printer 10 is exemplified as the image processing apparatus. However, the present invention may be applied to a printer such as an electrophotographic method or a dot impact method, or a scanner or the like in addition to the printer. The present invention may be applied to a multifunction machine having the above functions.

  In the above-described embodiment, the case support 44 is biased to the use position with the projection 44c in contact with the stopper 46 by the torsion coil spring 42, whereby the chip antenna 41a is positioned at the use position. However, instead of the stopper 46, a thread 86 for connecting the printer main body 12 and the case support 44 may be provided. Specifically, as shown in FIG. 8, when the cover 30 is opened, the case support 44 rotates from the state pressed by the cover 30 in the direction of rising by the torsion coil spring 42. Then, when the case support 44 becomes approximately 90 ° with respect to the installation surface of the printer main body 12, the thread 86 may be tightly pinched to prevent the case support 44 from rotating further.

  In the embodiment described above, the case axis of the antenna case 41 is shared with the cover support axis 32, but may be provided separately. If it carries out like this, the freedom degree of arrangement | positioning of the antenna case 41 can be raised.

  In the embodiment described above, the cover 30 is attached to the cover support shaft 32 and is rotatable. However, the cover 30 may be removable.

  In the embodiment described above, as shown in FIG. 1, the antenna case 41 is connected to the case support 44 provided on one side of the upper surface, and as the cover 30 rotates from the closed position to the open position, Although the cover 30 is rotated from the storage position to the use position, when the cover 30 is in the closed position, the cover 30 is pressed into a state of being immersed in the printer main body 12 (see FIG. 9A), and the cover 30 is As it rotates from the closed position to the open position, it protrudes to the upper side of the printer main body 12 and moves to a use position (see FIG. 9B) where the angle with the photo printer 10 installation surface is approximately 90 °. Also good.

  The operation at this time will be described in more detail with reference to FIG. FIG. 9 is an explanatory diagram for explaining the operation of the antenna case 41 of another embodiment. At this time, the lower surface of the antenna case connection port 80 is connected to the lower portion of the antenna case storage space 84 via the spring 82. When the photo printer 10 is not in use, as shown in FIG. 9A, it is pressed by the cover 30 and the antenna case 41 is stored in an antenna case storage space 84 provided on the upper surface of the printer main body 12. For this reason, damage to the antenna case 41 can be prevented. On the other hand, when the photo printer 10 is used, as shown in FIG. 9B, the cover 30 moves to the open position, so that the antenna case 41 is not pressed by the cover 30. Therefore, the antenna case 41 is pushed up to the upper surface of the printer main body 12 by the spring 82. At this time, since the antenna case storage space 47 is provided so as to be approximately 90 ° with respect to the installation surface of the printer main body 12, the antenna case 41 is positioned on the upper surface of the printer main body 12 at a position of approximately 90 °. Is done. Thereby, the chip antenna 41a can be positioned at a position suitable for receiving radio waves.
