Description

  The present invention relates to a handle for carrying an apparatus main body, and more particularly to a rotatable handle.

  Conventionally, there are handles that are provided to carry the apparatus main body and are fixed to the main body and cannot be stored, and there are handles that are movably supported by the apparatus main body and can be stored. The handle that is movably supported by the apparatus main body and can be accommodated is generally configured to be accommodated by sliding or rotating the handle relative to the apparatus main body.

  The configuration in which the handle is accommodated by sliding requires that a part for accommodating and sliding the handle be formed in a part of the apparatus main body, which has been a factor that hinders downsizing of the main body.

In addition, the handle for rotating storage can be realized with a smaller configuration than the sliding storage, but the handle member also rotates during carrying. Therefore, a mechanism for locking the rotary handle has been developed in consideration of safety so as not to rotate (see Patent Document 1).
JP 2003-46263 A

  However, in the above conventional example, a mechanism for switching between lock and release for fixing the handle is provided. Therefore, when the handle is rotated from the stowed state to the carrying position and locked, the lock state is released when the handle is grounded after being carried, and the lock switching mechanism is operated when the handle is rotated and stowed. Become. That is, it is necessary to operate the switching mechanism every time the lock and release are performed, which is inconvenient because the number of operations for carrying is increased. In addition, this switching mechanism increases the number of parts constituting the handle, which increases the cost.

  In order to solve such a problem, an object of the present invention is to provide a handle with good operability that does not require a lock and release operation by a switching mechanism each time the handle is locked and released.

  In order to solve the above problems, the present invention has the following configuration.

A handle provided with a rotating shaft and rotatably supported by the apparatus body;
A handle locking mechanism having a bearing portion for a rotating shaft portion provided in the apparatus for supporting the handle,
The rotation of the rotation shaft portion is locked by the movement of the rotation shaft portion.

  According to the present invention, in the rotatable handle, the rotation of the rotating shaft is locked by the movement of the rotating shaft. Therefore, the rotation of the handle can be easily controlled by simply moving the handle without performing a special switching operation for locking or unlocking. In addition, the rotation lock of the handle can be realized with a small number of components.

  In addition, it is possible to realize a handle for carrying the device body safely and easily without being aware of the operation of the lock.

(Example 1)
1 and 2 are schematic views of an apparatus having a handle according to the present invention. FIG. 1 is a perspective view of the handle in the storage position. When no force is applied to the handle as shown in FIG. 1, the handle is urged downward by its own weight and rotates to the handle retracted position as shown in FIG. FIG. 2 shows a state where the handle is rotated in the direction of the arrow in FIG. 1 from FIG. 1 and the handle is rotated to the first position for carrying. From this state, the apparatus body is lifted in the direction of arrow A to carry the apparatus, so that the handle and the rotating shaft portion move in the direction of arrow A, and the handle is fixed. An arrow A is a direction in which the apparatus main body is lifted, and a direction in which the user applies a force to the handle to lift the apparatus main body.

  FIG. 3 is a cross-sectional view of the vicinity of the handle rotation shaft portion 33 in a state in which the handle is in the storage position, and reference numeral 31 denotes a housing exterior component of the apparatus main body. Reference numeral 32 denotes a handle, 33 denotes a rotating shaft portion formed integrally with the handle, 33a denotes a fitting shape formed integrally with the rotating shaft portion, and 34 denotes a bearing portion formed integrally with the apparatus main body 31. . There are two rotation shaft portions and two bearing portions, respectively, and these two rotation shaft portions form a rotation shaft when the handle rotates. In addition, the handle is formed symmetrically, and the two rotating shafts and bearings are also surfaces perpendicular to the direction of the rotating shaft of the handle and are arranged in a plane-symmetrical shape with respect to the surface passing through the center of the handle. Has been.

  4 and 5 show a state in the middle of rotating the handle from the housed position to the first position for carrying, and the handle 32, the rotary shaft 33, and the fitting shape 33a rotate integrally. From the stowed state of the handle 32 to the first position for carrying, the fitting shape 33a provided on the rotating shaft part and the bearing part 34 interfere with each other, and the rotating shaft part restricts movements other than rotational movement. ing.

  In the position of FIG. 4, 33 a and 33 b interfere with the bearing portion 34, so that the handle cannot move in the lifting direction A of the apparatus main body in the upper part of the figure. Even when the handle is in the position of FIG. 5, 33 a and 33 b interfere with the bearing portion 34, and the rotating shaft portion 33 cannot move in the lifting direction A of the upper apparatus body in the drawing. Moreover, as shown in FIG.4 and FIG.5, it is restricted by the axis | shaft and the bearing to the up-down direction of a figure. FIG. 6 shows the handle in the first position for carrying. At this time, the shape 33 a provided on the bearing portion 34 and the rotation shaft portion does not interfere with each other, and the rotation shaft portion 33 can move in the handle lifting direction A with respect to the bearing portion 34. Further, in the case of the illustrated handle, a part of the shape 33b provided on the rotating shaft part and the 34b provided on the bearing part interfere with each other, thereby counterclockwise (B In the direction of). Further, 33a also serves as a lock function for stopping rotation at the first position for carrying during handle operation. This lock function will be described with reference to FIG.

  FIG. 7 shows a state where the handle is lifted in the direction A by the operation of carrying the apparatus main body from the first carrying position shown in FIG. In this state, the fitting shape 33a provided on the rotating shaft portion is fitted with the 34a provided on the bearing portion to restrict the rotation of the handle 32 and the rotating shaft portion 33.

  Further, when the carrying of the apparatus main body is finished and the force in the direction A applied to the handle is lost, the rotating shaft portion 33 moves downward (opposite to the direction A) by the weight of the handle. At this time, the urging member 35 collides with the rotating shaft portion 33, and a moment is applied to the rotating shaft portion 33. Therefore, the handle 32 rotates in the direction of arrow C in FIG. 7 and rotates to the handle storage position in FIG. Therefore, the user moves the handle to the original storage position simply by placing the apparatus main body that has been lifted at a desired position and releasing the hand from the handle. Further, the urging member 35 may be easily pushed downward so as not to affect the rotation of the rotating shaft during the rotation of the handle shown in FIGS. Further, the urging member 35 is not limited to the shape shown in FIG. 7 because it is sufficient to apply a moment to the rotating shaft portion. A force may be applied to the rotating shaft with a spring or the like.

  As described above, according to the present invention, the user can restrict the rotation of the handle when carrying the apparatus main body by only a series of moving operations of the apparatus main body without being aware of the mechanism with a small number of components.

  In the first embodiment, the rotating shaft portion has a convex shape and the bearing portion has a concave shape, and the handle is locked by fitting the concave and convex shapes. The shape is not limited to this. Any shape may be used as long as the rotary shaft moves and the handle is locked. Therefore, you may provide a concave shape in a rotating shaft part, and a convex shape in a bearing part. Other examples of the shapes of the rotating shaft portion and the bearing portion will be described in the third embodiment. Further, in this embodiment, by providing a convex shape on the rotating shaft side and a concave shape on the bearing portion side, the handle rotating operation is smoothly performed without obstructing the rotation by these shapes when the handle is rotated. It is like that.

(Example 2)
FIG. 8 is a perspective view of the entire portable printer device having a handle lock function as in the first embodiment. A display unit 91 displays image information, a print setting screen, and the like, and is a retractable type. The user can rotate the display unit to a desired position and fix the display device at an easily viewable position. Reference numeral 92 denotes printing paper. 9 is a cross-sectional view of the printer shown in FIG. 8, in which 93 is a paper case and 94 is a printing mechanism.

  The handle 32 of the second embodiment has a lock function similar to that of the first embodiment. Furthermore, the handle according to the second embodiment has a shape that does not collide with the movable range of the display unit 95 or the paper case when the handle is locked. Therefore, even if image selection, print settings, printing operations, etc. are performed using the display unit while the handle is locked, each operation can be performed smoothly without interfering with these operations. Can do the operation.

  In the above embodiment, the shape of the handle is such that the movable area of the paper case 93 and the display unit 95 is avoided. However, in addition to this, when the paper transport path, the paper storage unit, and the like are arranged in the vicinity of the position when the handle is locked, it is better to make the handle shape so as not to affect these. Thus, even if the shape of the handle becomes complicated, the handle lock of the present invention makes it possible to stabilize and easily carry the printer device.

  Further, in the printer device of the second embodiment, the axis that is the axis of the actual rotation of the handle is not arranged on the vertical direction of the center of gravity of the printer device. For this reason, when the printer device is lifted with this handle, the printer device is lifted obliquely, and the state becomes very unstable. Therefore, by applying the handle lock function as in the present invention, the printer device can be stably carried regardless of the handle center of gravity regardless of the center of gravity of the handle, and the degree of freedom of layout of the handle with respect to the device is increased. .

(Example 3)
The apparatus shown in FIGS. 10 and 11 and the apparatus shown in FIGS. 12 and 13 are schematic views of an apparatus including a handle having a handle lock function similar to that of the first embodiment. These are different from the first embodiment in the shapes of the rotating shaft portion and the bearing portion. Other than that, the configuration is the same as that of the first embodiment. In the first embodiment, the rotating shaft portion has a convex shape and the bearing portion has a concave shape. However, even in the case of the rotating shaft portion and the bearing portion as in the third embodiment, the same as in the first embodiment. Can be expected.

  A handle 103 is rotatably supported on the apparatus main body 104 of FIGS. The rotating shaft portion 102 provided on the handle has a shape in which a cylindrical curved surface is cut off at two places and corners are provided on the cylindrical curved surface. Reference numeral 101 denotes a bearing unit 101 provided in the apparatus main body 104. FIG. 10 shows a state in which the handle is locked, and FIG. 11 shows a state in which the handle 103 is rotating. During rotation of the handle, when the rotary shaft portion 102 rotates at the bearing portion 101 and the handle is rotated to the carrying position, the rotary shaft portion 102 can move to the concave portion 101a of the bearing portion. When the rotating shaft part 102 moves in the lifting direction and engages with 101a, the rotating operation of the handle is restricted and the handle is locked.

  Compared with the shape shown in the first embodiment, the shape of the rotary shaft portion 102 is engaged with the concave portion 101a of the bearing portion, so that the position of the handle is more firmly controlled. Can do. Further, when the rotation angle of the handle 102 is less than 180 degrees, the rotation shaft portion can be moved only at one position, and when it is 180 degrees or more, the shaft can be moved at two positions.

  A handle 203 is rotatably supported on the apparatus main body 204 of FIGS. The rotating shaft 202 provided on the handle is a regular hexagon. Reference numeral 201 denotes a bearing unit 201 provided in the apparatus main body 204. FIG. 12 shows a state in which the handle is locked, and FIG. 13 shows a state in which the handle 203 is rotating.

  FIG. 12 shows a state where the handle 203 is rotating. During rotation of the handle, when the rotary shaft 202 is rotated by the bearing 201 and the handle is rotated to the carrying position, the rotary shaft 202 can move to the concave portion 201a of the bearing. When the rotation shaft portion 202 moves in the lifting direction and engages with 201a, the rotation operation of the handle is restricted and the handle is locked.

  Since the shape of the rotation shaft portion 202 is a regular polygon, the rotation shaft portion can be moved at a certain angular position. For example, FIG. 13 is a diagram showing a state in which the handle is being rotated. In this case as well, the handle is movable in the direction A. For this reason, it is good when the shaft is moved at a plurality of positions and the handle can be locked.

Example 4
In the fourth embodiment, a printer having the handle lock function described in the first to third embodiments will be described. In the printer of this embodiment, various operations of the printer are controlled according to the position of the handle, and control for restricting the rotation of the handle and the movement of the rotating shaft portion is performed according to the operation status of the printer.

Assume that the printer of this embodiment has a handle lock function similar to that of the first embodiment.
First, the printer 400 of this embodiment will be described.

  FIG. 14 is a block diagram of the printer 400.

  A CPU 401 is a control unit that controls the entire printer 400. The control unit reads a program from a memory (not shown) and performs control of each block, arithmetic processing, and the like based on the read program. .

  Reference numeral 402 denotes an IO control unit that performs control to read data recorded in a memory card 403 mounted on the printer.

  Reference numeral 404 denotes a handle position detection unit that detects a handle position by a handle position detection sensor (not shown) provided in the rotary shaft unit 33 or the bearing unit 34.

  Reference numeral 405 denotes a handle control unit for preventing the handle from rotating from the storage position.

  A printing unit 406 prints an image stored in the memory card 403 read by the IO control unit 402. The printing unit converts the image data sent from the IO control unit into print data, and prints the image by transferring ink to recording paper by a thermal head (not shown). It also feeds and discharges recording paper during printing.

  Reference numeral 407 denotes a display unit such as an LCD, which displays an image stored in the memory card 403 read by the IO control unit 402, a print setting screen, and the like.

  Reference numeral 408 denotes an operation unit that analyzes an instruction input to an operation button (not shown) by the user and transmits the instruction to the control unit. The control unit 401 controls each block by issuing a command to each block in response to an instruction input from the operation unit 408.

  In this printer, the user operates the operation unit 408 while viewing the image displayed on the display unit 407 to instruct image printing. When a print instruction is input, the image data to be printed is read and the print image is printed by the printing unit. If the handle is lifted and the printer 400 is carried during execution of this printing, vibration during lifting or carrying will affect the paper feed process, paper discharge process, and print process, resulting in a decrease in print image quality, There is a risk of jamming of the recording paper. Therefore, in this embodiment, when these processes are started, the handle control unit 405 regulates the rotation of the handle so that the handle does not rotate from the storage position. As a rotation restricting method, for example, as shown in FIG. 15, a rotation preventing member 305 is provided. The anti-rotation member 305 is retracted to the position D in FIG. 15 during normal handle rotation. However, when the printing process or the like is started, the rotation prevention member 305 is disposed at the position shown in FIG. The rotation of the provided rotation shaft portion 302 is restricted. Further, the concave portion of the bearing portion may be closed so that the rotating shaft portion is not locked.

  In addition, when the handle position detection unit 404 detects the position of the handle 303 and detects that the handle is in the lifted position, the printer 400 performs a printing operation (even if a print instruction is input from the user to the operation unit 408). Paper feed processing, paper discharge processing, printing processing, etc.) are not started. Similarly, when the handle is in the lifted position and the handle is locked, the printing operation is not started. Further, the display unit 407 displays that the handle is in the lifted position and the printing operation is not started, and notifies the user. Later, when the handle is returned to the storage position, the handle detection unit 404 detects this and starts the print instruction automatically, or starts printing when the user confirms the print and inputs the print instruction. .

  With such a configuration, the handle is lifted during the printing operation, and the printer can be prevented from being carried, so that it is possible to prevent the recording paper from being jammed and the printing image quality from being lowered due to the carrying.
