Hereinafter, the POS terminal as the example of the electronic device according to the embodiment is illustrated with reference to FIGS. 1-6.
FIGS. 1 and 2 are the front perspective view and the back perspective view showing a schematic brief configuration of the POS terminal according to the embodiment.
POS terminal 1 is an electronic device which is installed at a paying area of a shop and used for conducting registration processing and account processing of customer purchased commodity. As shown in FIGS. 1 and 2, the POS terminal 1 includes a main body 2, a keyboard 3, a display section for salesclerk (first display section) 4, a display section for customer (second display section) 5, a connecting member 8, a receipt printer 6, and a journal printer 7.
In the interior of the main body 2, an information processing section (not shown) which conducts various information processing or a storage section (not shown) which stores various information are arranged.
At one end of the upper side of the main body 2, the keyboard 3 as the input section which has various function keys such as a numerical keypad etc. for the salesclerk conducting various operations is arranged.
At one side of the upper side of the main body 2 and at the position adjacent to the keyboard 3 and the receipt printer 6 and the journal printer 7, a connecting member 8 is arranged. The connecting member 8 is connected to the main body 2 via a first shaft 81 (referring to FIGS. 4 to 6) in a manner of being able to rotate in a front-back direction (a direction in which the keyboard 3 is connected with the receipt printer 6 or the journal printer 7) meanwhile the connecting member 8 is connected via the second shaft 82 (referring to FIGS. 4 to 6) to the display section for salesclerk 4 in a manner of being able rotate in the front-back direction.
At the upper side of the main body 2 and at the position adjacent to the keyboard 3 and the receipt printer 6 and the journal printer 7, the display section for salesclerk 4 which displays various information such as processing details etc. to the salesclerk is installed via two connecting member 8 in a manner of being able to rotate in a front-back direction. Then, the power supply or various display data are provided from the main body 2 via the connecting member 8 to the display section for salesclerk 4. In addition, a given resistance force is applied against the rotation motion of the second shaft 82. By the resistance force, the display section for salesclerk 4 can adjust the angle relative to the connecting section 8 and can maintain a given angle.
The display section for customer 5 is connected to the end of the opposite side to the side which is connected to the connecting member 8 of the display section for salesclerk 4 via a shaft 52 in a manner of being able to rotate in the front-back direction. In usual usage state of the POS terminal 1, the display section for customer 5 is located above the receipt printer 6 and the journal printer 7 described below.
The display section for customer 5 displays various information such as purchased goods or billing amount etc. to the customer. The power supply or various display data are provided from the main body 2 via the connecting member 8 and the display section for salesclerk 4 to the display section for customer 5. Because of this, even if the display section for customer 5 is directly arranged above the main body 2, the power supply or various display data can be provided. In addition, a given resistance force is applied against the rotation motion of the shaft 52. By the resistance force, the display section for customer 5 can adjust the angle relative to the display section for salesclerk 4 and can maintain a given angle.
The display section for customer 5 is continuously arranged in the display section for salesclerk 4, thereby it is unnecessary to ensure a space for arranging the display section for customer 5 in the upper side of the main body 2, and the POS terminal 1 can be downsized with respect to the planar direction.
In usual usage state of the POS terminal 1, the display section for customer 5 is located above the receipt printer 6 and the journal printer 7 described below and does not project from the main body 2 in the planar direction. Therefore, the POS terminal 1 can be downsized with respect to the planar direction.
As shown in FIGS. 1 to 3, at lower part of the display section for salesclerk 4 and at the position adjacent to the keyboard 3, the receipt printer 6 and the journal printer 7 are arranged side by side in the planar direction.
The receipt printer 6 prints purchased commodity items or their total amount etc. onto the continuous-feed paper and sends it out as the receipt. The receipt printer 6 includes a storage section (not shown) which stores the roll shaped continuous-feed paper in its interior; a printing section (not shown) which prints onto the continuous-feed paper; a paper feed section (not shown) which transports the continuous-feed paper from the storage section through the printing section to the exterior of the receipt printer 6; a cover 62 which covers these components. The receipt made by printing onto the continuous-feed paper is ejected from the receipt outlet 61 arranged in the cover 62.
The journal printer 7 prints data such as one-day sales result etc. stored in the storage section arranged in the interior of the main body 2 of the POS terminal 1 onto the continuous-feed paper and sends it out as the journal. The journal printer 7 includes a storage section (not shown) which holds the roll shaped continuous-feed paper in its interior; a printing section (not shown) which prints onto the continuous-feed paper; a winding section (not shown) which rewinds the print finished continuous-feed paper to a roll shape; and a cover 72 which covers these sections.
The receipt printer 6 and the journal printer 7 are arranged adjacent to the keyboard 3. Therefore, the POS terminal can be downsized in the planar direction.
In order to downsize the POS terminal 1 in the planar direction, the components are arranged adjacent to each other in the planar direction meanwhile it is preferred that the components are arranged in a manner of being within the superior surface of the main body 2 in the planar direction, that is, not projecting from the main body 2 in the planar direction. On the other hand, in order to ensure the operability of the keyboard 3, it is be necessary to leave a given interval between the display section for salesclerk 4 and the keyboard 3.
Therefore, in case that the display section for salesclerk 4 is parted from the keyboard 3 and the display section for salesclerk 4 rotates in a direction covering the upper sides of the receipt printer 6 and the journal printer 7, the POS terminal 1 according to the present embodiment is configured in a manner that the display section for customer 5 abuts the main body 2 or the cover 62, 72 (referring to FIGS. 1, 2, and 4). That is, the rotation of the display section for salesclerk 4 towards the direction seceding from the keyboard 3 is conducted only to a position (first position) where the display section for customer 5 abuts the main body 2 or the cover 62, 72, and the rotation is controlled not to surpass the position.
Because of this, the rotation of the display section for salesclerk 4 can be controlled such that it is within the range in which the display content is easy to be seen by the salesclerk. In addition, in the case that the display section for customer 5 moves with the rotation of the display section for salesclerk 4, the display section for customer 5 is constantly within the superior surface of the main body 2 in the planar direction, and does not project from the main body 2. Therefore, the increase in size of the POS terminal 1 in the planar direction is effectively prevented, and a configuration with excellent space-saving property is obtained.
The display section for salesclerk 4 is arranged at the upper part of the main body 2 via the connecting member 8 arranged adjacent to the keyboard 3. That is, at the upper part of the main body 2, only the keyboard 3, the connecting member 8, the receipt printer 6 and the journal printer 7 are arranged adjacent to each other, and a configuration with excellent space-saving property in the planar direction is obtained.
The display section for salesclerk 4 is arranged in the main body 2 via the connecting member 8, accordingly in the usual usage state (referring to FIG. 1), in the display section for salesclerk 4 only the connecting member 8 offsets with respect to the keyboard 3, accordingly the operability of the keyboard 3 can be insured.
The rotation of the display section for salesclerk 4 of the POS terminal 1 according to above-described embodiment is illustrated with reference to FIGS. 4-6.
FIG. 4 is a side view of the usual usage state of the POS terminal 1. At this time, the display section for salesclerk 4 of the POS terminal 1 faces to the salesclerk side meanwhile the display section for customer 5 faces to the customer side. In addition, in this state, passing through the space formed by the main body 2 and the connecting section 8 and the display section for salesclerk 4, a state in which the receipt outlet 61 is exposed to the salesclerk side is obtained (referring to FIG. 1).
Because of this, the salesclerk can take out with hand the receipt ejected from the receipt outlet 61 which is below the display section for salesclerk 4 through a space formed by the main body 2 and the connecting member 8 and the display section for salesclerk 4.
However, in the state of FIG. 4, the display section for salesclerk 4 covers the upper side of the receipt printer 6 and the journal printer 7, and the display section for salesclerk 4 is at the position within the motion range D of the cover 62 of the receipt printer 6 and the cover 72 of the journal printer 7. Therefore, in this state, if the cover 62, 72 are opened they will contact with the lower hem of the display section for salesclerk 4, accordingly the cover 62, 72 cannot be opened and closed, and the roll paper cannot be transported into and from the receipt printer 6 or the journal printer 7.
Therefore, in the case that when the roll paper is transported into and from the receipt printer 6 or the journal printer 7 the cover 62, 72 must be opened and closed, the display section for salesclerk 4 must be evacuated out of the motion range D of the cover 62, 72.
In order to evacuate the display section for salesclerk 4 out of the motion range D of the cover 62, 72, first, as shown in FIG. 5, the display section for salesclerk 4 is made to rotate and stand up via the second shaft 82 towards the keyboard 3. At this time, the lower hem 41 of the rotated display section for salesclerk 4 abuts against the connecting member 8, thereby the rotation of the display section for salesclerk 4 is controlled to a given angle meanwhile this state is maintained by the resistance force against the rotation of the second shaft 82. In addition, the display section for customer 5 which is connected to the display section for salesclerk 4 also moves with the movement of the display section for salesclerk 4, and the display section for customer 5 evacuates out of the motion range D of the cover 62, 72.
As shown in FIG. 6, the connecting member 8 is made to rotate and stand up via a first shaft 81 towards the keyboard 3. At this time, because the end face 83 of the connecting member 8 abuts against the superior surface of the main body 2, the rotation of the connecting member 8 via the first shaft 81 is controlled in a state to the given angle, accordingly the rotation of the display section for salesclerk 4 is also controlled. That is, the rotation of the display section for salesclerk 4 towards the keyboard 3 is controlled at a given position (second position). Then, the display section for salesclerk 4 is configured in a manner of being able to rotate between the above-described first position and the above-described second position.
Thus, the display section for salesclerk 4 further moves from the state of FIG. 5 towards the keyboard 3 side thereby evacuates out of the motion range D of the cover 62, 72, and the upper sides of the receipt printer 6 and the journal printer 7 are opened. In addition, following the display section for salesclerk 4, the display section for customer 5 also further moves from the state of FIG. 5 towards the keyboard 3 side, but in the case the display section for salesclerk 4 is at the second position, the display section for customer 5 is constantly within the superior surface of the main body 2 and dose not project from the main body 2 in the planar direction. Therefore, increase in size of the POS terminal 1 in the planar direction is effectively prevented, and a configuration with excellent space-saving property is obtained.
Then, the display section for salesclerk 4 and the display section for customer 5 both evacuate out of the motion range D of the cover 62, 72, accordingly the cover 62, 72 can be opened and closed, and a state in which the roll paper can be transported into and from the receipt printer 6 or the journal printer 7 is obtained. In addition, in this state, a given interval is formed between the display section for salesclerk 4 and the keyboard 3 by the connecting member 8, accordingly an incorrect operation of the keyboard 3 due to contact of the display section for salesclerk 4 can be prevented.
In accordance with the POS terminal 1 according to the above-described embodiment, the display section for salesclerk 4 rotates and stands up towards the keyboard 3 via the second shaft 82, and the connecting member 8 further rotates and stands up towards the keyboard 3 via the first shaft 81. Thus, in the usual usage state, the display section for salesclerk 4 and the display section for customer 5 connected therewith which are located within the motion range D of the cover 62, 72 can evacuate out of the motion range of the cover 62, 72.
Because of this, in the usual usage state, the display section for salesclerk 4 and the display section for customer 5 can be arranged in a manner of being located within the motion range D of the cover 62, 72. That is, previously, the display section for salesclerk 4 and the display section for customer 5 are arranged out of the motion range D, accordingly the given space required between the display section for salesclerk 4 and the display section for customer 5 and the cover 62, 72 can be omitted, and the POS terminal 1 can be downsized in the planar direction.
When the display section for salesclerk 4 and the display section for customer 5 evacuate out of the motion range D of the cover 62, 72, first, the display section for salesclerk 4 and the connecting member 8 are folded around the second shaft 82 as the center, accordingly a compact state in which the display section for salesclerk 4 are adjacent to connecting member 8 is obtained. Then, the display section for salesclerk 4 and the connecting member 8 which have become to the compact state are moved by the rotation movement in which the first shaft 81 is the center, accordingly the motion range when the display section for salesclerk 4 and the display section for customer 5 evacuate out of the motion range D of the cover 62, 72 can be reduced. In this way, the motion range between the display section for salesclerk 4 and the display section for customer 5 becomes smaller, accordingly the space required for installation of the POS terminal 1 can be reduced.
