Description

The present invention relates to a terminal device system, a cradle, and a terminal device, and acquires information from the terminal device and charges the terminal device via the cradle.

  Conventionally, there are a cradle and a terminal device that extract power from a terminal device and supply power for charging a battery built in the terminal device. Although the cradle has a signal terminal and a charging terminal that are always exposed, the terminal protrudes when the terminal device is inserted into the cradle to prevent short-circuiting between terminals and threading between the terminal and the terminal device. There are some (see, for example, Patent Document 1).

  However, in the conventional device, as a mechanism that the terminal pops out from the cradle, the lever pushed by the terminal device and the terminal part are configured like a seesaw, and the terminal is turned to the contact point of the terminal device by rotating around the fulcrum. I was holding it.

  However, in the structure in which the terminal is projected by the rotation operation, the pushing force of the lever that contacts the terminal device increases in proportion to the rotation of the seesaw member even if it is initially small in contact with the terminal device. When the terminal is held in the cradle, the terminal device is easily lifted by the force of the lever, and there is a possibility that the terminal and the contact may come off due to vibration or slight contact, or the terminal device may “float” and cause a contact failure. It was. This phenomenon is further promoted by increasing the springiness of the terminal in consideration of the contact between the terminal and the contact.

  The present invention has been made to solve the above-described conventional problems, and suppresses the force for pushing up the terminal device when the terminal of the cradle and the contact of the terminal device come into contact with each other, and the terminal and the contact are pressed with sufficient force. And a terminal device system, a cradle, and a terminal device that provide a smooth operation feeling.

  The terminal device system of the present invention is a terminal device system comprising a terminal device having a display unit and an operation unit on the front surface and a contact for performing charging and data communication on the lower portion of the back surface, and a cradle on which the terminal device is placed The cradle includes a rail and a slider provided with a lever and a terminal facing each other, and the slider moves on the rail with a force that the terminal device contacts the lever, and a stopper provided on the rail. A part of the slider is engaged to maintain the terminal in contact with the contact.

  With this configuration, it is possible to obtain a smooth operation feeling while suppressing the force by which the lever pushes up the terminal device while the terminal is in contact with the contact.

  Further, the cradle of the present invention has a rail, a lever and a terminal provided facing each other and a slider, and the slider moves on the rail, and the slider contacts the lever with the terminal device. And the stopper is provided on the rail and a part of the slider is engaged so that the terminal contacts the contact provided on the terminal device and maintains the other state.

  Even with this configuration, it is possible to obtain a smooth operation feeling while suppressing the force by which the lever pushes up the terminal device while the terminal is in contact with the contact.

  The terminal device according to the present invention further includes a rail, a slider provided with a lever and a terminal facing each other, and the slider moves on the rail by a force abutting on the lever by its own weight. A terminal device inserted into a cradle where a stopper provided on the rail engages with a part of the slider, wherein the contact is pressed against a terminal protruding from the cradle by pushing the lever with its own weight. Is provided on the back surface of the member in contact with the lever.

  Even with this configuration, it is possible to obtain a smooth operation feeling while suppressing the force by which the lever pushes up the terminal device while the terminal is in contact with the contact.

  Hereinafter, a terminal device according to an embodiment of the present invention will be described with reference to the drawings. In the present embodiment, a case of a terminal device and a cradle used for processing related to delivery of a package by a courier company is illustrated.

  The appearance and usage state of the cradle and the terminal device according to the embodiment of the present invention will be described with reference to FIGS. In the following, the configuration (main configuration) characteristic of the present invention will be mainly described.

  FIG. 1 shows the appearance of the cradle 1, FIGS. 2A and 2B show the usage state of the cradle 1 and the terminal device 4, and FIG. The cradle 1 has a recess 3 that receives the terminal device upward, and a terminal guide 2 that guides the terminal 32 that protrudes to the side surface near the bottom surface of the recess.

  The terminal device 4 shown in FIGS. 2A, 2B, and 3 has a display unit configured with an LCD on the front surface, an input unit configured with numeric keys and function keys, and is attached to a package on the back surface. There are an optical head unit 21 for reading a barcode, a grip 22 for holding a terminal device, and a contact 23 for charging and data communication.

  The cradle 1 includes a slider 31 and a slide rail base 40 inside as shown in FIG. 6 and FIG. 7 which is a sectional view.

  As shown in FIG. 4, the slider 31 has a lever 33 at a position facing the terminal 32. The terminal 32 is made of phosphor bronze or piano wire, which has good conductivity and high spring property, and is gold-plated. The terminal 32 does not come out in the recess 3 in the state shown in FIG. 2A, and prevents a short circuit even if a foreign object such as a metal clip rolls in. Even if a metal foreign object falls into the concave portion, the terminal guide is formed on the side surface, so that the terminal 32 falls to the bottom by the protruding operation and seriously affects operations such as charging from the terminal 32 and data extraction. Is not given.

  The lever 33 and the terminal 32 are formed on an integral slider 31. Further, since the terminal is formed by a wire spring and the protruding portion is long, the base is positioned by the terminal holder 36 and is electrically connected to the slider substrate 37 by soldering. The slider substrate 37 fixes the terminal 32 together with the terminal holder 36 and is connected to an external connector (not shown) provided on the body 51 by a flexible flexible substrate (not shown).

  Further, the slider 31 slides and is guided by a slide rail A41 and a slide rail B42 provided on the slide rail base 40 shown in FIG. The slide rail base 40 is provided with a stopper B45 that is pressed and stopped by the slide pin B35 of the slider 31 and a spring 43 that biases the slider. The spring 43 has a target shape and is engaged with a spring hook 38 provided with a spring detachment prevention flange provided on both sides of the slider 31 to push the slider 31.

  When the terminal device is not inserted by the spring 43, the slider 31 stops in a state where the slide pin A34 rides on the slide rail A41, rides on the slide pin B35 slide rail B42, and is pressed against the stopper B45. This position is a fixed position in a state where the terminal device is not inserted.

  In this fixed position, the terminal 32 does not protrude into the recess of the cradle, and the lever 33 protrudes into the recess 3. As shown in the cross-sectional view of FIG. 7, the recess 3 is angled so that the display unit of the terminal device is inserted upward toward the lever. The slider 31 is easy to move due to increased force. Further, by providing this angle, there is also an effect of making the display of the terminal device easier to see when it is set in the cradle as shown in FIG.

  When the terminal device 4 is inserted into the recess 3 shown in FIG. 1, the lower front corner of the terminal device comes into contact with the slope of the lever 33, and a horizontal component is generated on the slider 31 by the slope to move the slider. Since a vertical component force is simultaneously generated in the slider, when the slide pin B35 provided on the slider reaches the stopper A44 provided at one end of the slide rail, it enters the stopper A44 and stops. On the contrary, when the terminal device 4 is taken out from the cradle 1, the vertical component force is lost, so that the slide pin B 35 is disengaged from the stopper A 44 and returned to a fixed position by the spring 43.

  Thus, while the slider 31 slide pin B is engaged with the stopper A, the return force by the spring 43 is suppressed, so that the contact 23 and the terminal 32 come into stable contact.

  Furthermore, since the engagement between the slide pin B35 and the stopper A44 also cancels out the pressure contact force with which the terminal 32 pushes the contact 23 of the terminal device, the contact force is further stabilized, and safe data reading and power supply are possible. Can be done.

  8 and 9 show the positional relationship between the slider 31, the slide rail A41, and the slide rail base 40 that is integral with the slide rail B42. FIG. 9 shows how the slide pin B35 engages with the stopper A44. FIG. 8 shows a state where the slider 31 is in a fixed position.

  In order to maintain the state of FIG. 9, a vertical component force from the lever 33 due to the weight of the terminal device is required as shown in FIG. When there is no vertical component force of the terminal device, the engagement between the slide pin B35 and the stopper A44 is shallow, and the vertical component force by the spring 43 is superior to the vertical component force due to the weight of the slider 31. Accordingly, the slider 31 is pushed back to a fixed position by the spring 43. The slider 31, the rail, and the like are preferably made of a resin (for example, a fluororesin) that has a low friction coefficient and is not easily worn down.

  Further, since the terminal 32 has a spring property, vibration is likely to occur when the spring constant is lowered. However, if a high spring constant is given, the contact of the terminal device may be damaged. For this reason, it is easier to stabilize the operation by increasing the displacement with a low spring constant and configuring the contact, but there is a problem that the contact point is not stable because the movable range is large.

  In order to solve this contradiction, the terminal 32 is guided by a terminal holder near the portion fixed to the slider substrate 37, and the terminal 32 near the contact passes between the slits provided in the terminal guide 2 in the lateral direction of the tip of the terminal 32. Suppresses displacement and vibration.

  The terminal device 4 shown in FIG. 3 is provided with a contact 23 for charging or data communication under the grip 22 on the back side of the device (opposite side of the operation unit). A lower part of the surface of the terminal device, in particular, an end part thereof is curved gently so as to contact the lever 33, and is preferably made of hard plastic, metal or the like. Providing a curve here and using a hard material also has the effect of improving the anti-drop performance of the terminal device.

  The embodiments of the present invention have been described above by way of example, but the scope of the present invention is not limited to these embodiments, and can be changed or modified according to the purpose within the scope of the claims. is there.

  As described above, the terminal device according to the present invention relates to a terminal device and a cradle that charges and communicates with the terminal device.
